Between the descriptions of the locking assembly of the present invention, first, an application scenario of the locking assembly is described, and the locking assembly according to the present invention can be applied to locking and unlocking of a lifting member as well as locking and unlocking of other moving members other than the lifting member, and the locking assembly can be applied to furniture such as a table, a cabinet, etc., and also to electric appliances such as a refrigerator, a retail cabinet, etc. The locking assembly according to the invention can also be applied in other application scenarios, where the invention is not specifically described, as long as the locking assembly can lock and unlock the member to be locked, where and hereinafter the member to be locked refers to a member that is locked in a certain specific position in the locked state of the locking member 2, and that can move freely in a movement path in the unlocked position of the locking member 2, such as a lifting member or a sliding member other than a lifting member, etc.

A lock assembly according to an embodiment of the first aspect of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 12, a locking assembly according to an embodiment of the present invention includes a mount and a locking member 2. The mount is formed with a transition aperture 112 and is adapted to switch between a closed state and an open state. The locking piece 2 is movably arranged on the mounting seat, and the locking piece 2 is provided with an unlocking position suitable for unlocking the piece to be locked and a locking position suitable for locking the piece to be locked. In the open state, the locking member 2 is adapted to pass through the switching hole 112 to switch between the locking position and the unlocking position; in the closed state, the locking member 2 is maintained in the locking position. During the switching of the locking member 2 from the locking position to the unlocking position, at least a portion of the locking member 2 passes through the switching hole 112.

According to the locking assembly provided by the embodiment of the invention, when the mounting seat is in the closed state, the locking piece 2 can be maintained at the locking position so as to lock the piece to be locked, and when the mounting seat is in the open state, the locking piece 2 can be switched between the unlocking position and the locking position through the switching hole 112, so that the piece to be locked can freely move only when the mounting seat is in the open state, and the piece to be locked can be conveniently taken out or continuously moved; under the condition that the mounting seat is in a closed state, the to-be-locked piece is locked, and at the moment, the to-be-locked piece cannot move freely, so that the stability of the structure is guaranteed, and the use safety is guaranteed.

It should be noted that, the above-mentioned closed state and open state of the mounting seat are aimed at whether the locking member 2 can pass through the switching hole 112, that is, in the closed state of the mounting seat, the locking member 2 cannot pass through the switching hole 112, so that the locking member 2 can only be maintained in the locking position; in the open state of the mount, the locking member 2 may pass through the switch aperture 112 (i.e., at least a portion of the locking member 2 may extend into the switch aperture 112), and thus the locking member 2 may be switched between the locked position and the unlocked position.

The switching between the open state and the closed state of the mounting seat can be at least realized by the following modes:

The first way is to control the position of the conversion hole 112 to correspond to the position of the locking piece 2 or not to realize the switching of the state of the mounting seat, namely when the position of the conversion hole 112 corresponds to the position of the locking piece 2, the mounting seat is in an open state, and the locking piece 2 can pass through the conversion hole 112; when the position of the switching hole 112 does not correspond to the position of the locking member 2, the mounting seat is in a closed state, and the locking member 2 cannot pass through the switching hole 112. It should be noted that, in the first mode, when the mounting seat is in the open state, the conversion hole 112 is necessarily in the open state; when the mounting seat is in the closed state, the switching hole 112 may be in an open state or in a closed state.

The second way is to switch the state of the mounting seat by opening or closing the switching hole 112, that is, when the switching hole 112 is in the opened state, the mounting seat is in the opened state, and the locking piece 2 can pass through the switching hole 112; when the switch hole 112 is in the closed state, the mount is in the closed state, and the locking member 2 cannot pass through the switch hole 112. It should be noted that, in the second embodiment, the position of the switching hole 112 corresponds to the position of the locking member 2 regardless of whether the mounting seat is in the open state or the closed state.

A detailed explanation of the two modes will be described below. In addition, the switching between the open state and the closed state of the mounting seat can be achieved in other manners, and the invention is not limited in particular herein.

According to the embodiment of the present invention, the "movable" in which the locking member 2 is movably disposed in the mounting seat "may refer to both being rotatable and slidable, and may refer to other movement types, and the movement type of the locking member 2 is not particularly limited in the present invention, as long as the locking member 2 is movable and the locking member 2 is adapted to pass through the conversion hole 112 in the open state, wherein the movement manner of rotation may be realized by hinging, and the movement manner of sliding may be realized by guiding grooves. Furthermore, "the locking member 2 is adapted to pass through the switching hole 112 to switch between the locking position and the unlocking position" only requires that the locking member 2 can pass through the switching hole 112 at least in part to achieve the switching of the position of the locking member 2.

According to an embodiment of the invention, in the open state, since the switch aperture 112 is in the open state or the position of the switch aperture 112 corresponds to the position of the locking member 2at this time, the locking member 2 has the possibility of moving in the direction towards the switch aperture 112, i.e. the locking member 2 has a certain degree of freedom of movement in the direction towards the switch aperture 112, the switch aperture 112 forms a movement path through which the locking member 2 can move, and the locking member 2 can switch positions when at least a part of the locking member 2 passes the switch aperture 112. For example, the locking member 2 is switched from the locking position to the unlocking position, at least a part of the locking member 2 is retracted into the switching hole 112, so that the locking member 2 is out of the movement path of the member to be locked, at this time, the member to be locked can be prevented from being limited by the locking member 2 and can move, so that a user can conveniently take out the member to be locked or make the member to be locked move continuously; in the closed state, since the switching hole 112 is in the closed state or the position of the switching hole 112 does not correspond to the position of the locking member 2at this time, the locking member 2 is restricted from moving in a direction away from the member to be locked, and the locking member 2 is restricted in the locked position at this time, thereby causing the locking member 2 to be located in the movement path of the member to be locked, and the locking effect is exerted on the member to be locked.

According to some embodiments of the present invention, if the second mode is adopted to switch the state of the mounting seat, a valve or a structure similar to the valve may be disposed on the mounting seat, so that the switching hole 112 on the mounting seat may be opened or closed by other components (such as a valve).

In one embodiment of the invention, the mounting is provided with a valve adapted to open or close the switch aperture 112 such that the switch aperture 112 of the mounting is switched between a closed state and an open state. Thus, the switching hole 112 can be opened or closed by controlling the valve, and the operation is simple and convenient. The valve may be controlled manually or electrically, and the present invention is not limited herein.

According to other embodiments of the present invention, if the above manner is adopted to achieve the switching of the state of the mounting base, the change of the relative position between the switching hole 112 and the locking member 2 may be caused by a change of the internal structure of the mounting base, for example, the mounting base includes two parts which are a first part and a second part, respectively, the switching hole 112 is formed in one of the first part and the second part, the locking member 2 is provided in the other of the first part and the second part, and the relative movement between the first part and the second part occurs such that the relative position between the switching hole 112 and the locking member 2 is changed. The structure of the mounting seat may be other types of structures, and the present invention is not limited thereto.

As shown in fig. 1 and 2, in another embodiment of the present invention, the mounting base includes a mounting housing 11 and a moving member, the mounting housing 11 defines a moving space 111, a conversion hole 112 is provided in an inner wall of the moving space 111, and the locking member 2 is movably provided in the moving member. The moving member is slidably fitted in the moving space 111 to switch the switching hole 112 of the mount between the closed state and the open state. In this way, the mount is changed in the relative position between the switching hole 112 and the locking member 2 by the relative movement between the mount housing 11 and the moving member, so that the mount is switched between the closed state and the open state. For example, when the moving member moves to the position of the corresponding switching hole 112 in the moving space 111, the position of the locking member 2 corresponds to the position of the switching hole 112, so that at least part of the locking member 2 may extend into the switching hole 112, so that the locking member 2 is located outside the movement path of the member to be locked, and at this time, the member to be locked is unlocked; when the moving member does not correspond to the position of the switching hole 112, the locking piece 2 is blocked by the inner wall of the moving space 111, and the inner wall of the moving space 111 restricts the movement of the locking piece 2 in a direction away from the piece to be locked, so that at least part of the locking piece 2 is located in the movement path of the piece to be locked, so that the piece to be locked is locked.

The movement of the moving member in the movement space 111 may be a rotation, a rolling, a sliding, a lifting or a like movement, and is not particularly limited herein, as long as the moving member can move relative to the mounting case 11.

As shown in fig. 1 to 12, the drawer assembly according to the second aspect of the embodiment of the present invention includes a locking assembly having a mounting housing 11 and a moving member in the first aspect of the embodiment of the present invention, and further includes a member to be locked.

The part to be locked is an inner drawer 3, the moving part is provided with a mounting groove 121 for mounting the inner drawer 3, the inner wall of the mounting groove 121 is provided with a through hole which is suitable for passing through the locking part 2, and in the unlocking position, the inner drawer 3 can slide in the mounting groove 121; in the locking position, the inner drawer 3 is locked to the mounting groove 121.

According to the drawer assembly provided by the embodiment of the invention, when the mounting seat is in the closed state, the locking piece 2 can be maintained at the locking position so as to lock the piece to be locked, and when the mounting seat is in the open state, the locking piece 2 can be switched between the unlocking position and the locking position through the switching hole 112, so that the piece to be locked can freely move only when the mounting seat is in the open state, and the piece to be locked can be conveniently taken out or continuously moved; under the condition that the mounting seat is in a closed state, the to-be-locked piece is locked, and at the moment, the to-be-locked piece cannot move freely, so that the stability of the structure and the use safety are guaranteed.

According to an embodiment of the present invention, the installation groove 121 communicates with the outside through the hole, and the above-mentioned "movement path of the to-be-locked member" refers to: the inner wall of the mounting groove 121 defines a space.

As shown in fig. 3 to 6, when the moving member moves to the position corresponding to the conversion hole 112 in the moving space 111, the mounting seat is in an opened state, since the position of the locking member 2 corresponds to the position of the conversion hole 112, when the user needs to take out the inner drawer 3, the inner drawer 3 can be directly drawn out of the mounting groove 121, and during the process of drawing out the inner drawer 3, the inner drawer 3 presses the locking member 2 so that at least part of the locking member 2 extends into the conversion hole 112, thereby pushing the locking member 2 out of the mounting groove 121 via the through hole, and the inner drawer 3 can be smoothly drawn out.

As shown in fig. 1 and 2, when the position of the locking member 2 does not correspond to the position of the switching hole 112, the locking member 2 is blocked by the inner wall of the moving space 111, and the inner wall of the moving space 111 restricts the movement of the locking member 2 in a direction away from the inner drawer 3, so that at least part of the locking member 2 is located in the mounting groove 121, so that the inner drawer 3 is locked in the mounting groove 121.

Therefore, only when the moving part moves to a specific position, the inner drawer 3 can be smoothly taken out, so that the use safety of a user is ensured, foreign matters are prevented from falling into the mechanism, and the normal use of the drawer assembly is ensured. The specific position refers to the position of the corresponding conversion hole 112 in the moving space 111.

According to one embodiment of the invention, the inner drawer 3 is provided with a first projection 31 and the locking member 2 is provided with a locking projection 221; in the locking position, the locking protrusion 221 is adapted to stop the first protrusion 31. In this way, since the locking protrusion 221 is stopped on the moving path of the first protrusion 31 in the locking position, the inner drawer 3 cannot be taken out from the installation groove 121, thereby locking the inner drawer 3, and the structure is simple and stable.

As shown in fig. 1 to 4, according to an embodiment of the present invention, the locking member 2 is rotatably provided to the moving member, and the locking member 2 is formed with a switching portion 22, and in the opened state, the switching portion 22 is adapted to pass through the switching hole 112 to switch between the locking position and the unlocking position. In this way, the locking piece 2 is switched between the unlocking position and the locking position in a rotating manner, and the switching process is more stable.

As shown in fig. 3 to 6, according to one embodiment of the present invention, the inner drawer 3 is provided with a first projection 31, and the converting part 22 includes a locking projection 221 extending toward the inner drawer 3 and a stopping projection 222 extending toward the mounting housing 11.

In the open state of the mounting seat, the position of the stop protrusion 222 corresponds to the position of the switch hole 112, at which time the stop protrusion 222 is adapted to pass through the switch hole 112, so that the locking member 2 can be switched between the unlocking position and the locking position; in the closed state of the mounting seat, the position of the stop protrusion 222 does not correspond to the position of the switch hole 112, and at this time, the stop protrusion 222 cannot pass through the switch hole 112.

As shown in fig. 3 and 4, in the locking position, the locking protrusion 221 is adapted to stop the first protrusion 31, and the stop protrusion 222 is adapted to stop against the inner wall of the moving space 111.

In the locking position, the switching portion is locked between the inner drawer 3 and the mounting housing 11, the locking protrusion 221 is used to lock the inner drawer 3 to prevent the inner drawer 3 from being pulled out, the stopping protrusion 222 is used to stop against the inner wall of the moving space 111 to limit the movement of the locking member 2, the locking protrusion 221 is stopped above the first protrusion 31, that is, the locking protrusion 221 is stopped on the moving path of the inner drawer 3 to prevent the inner drawer 3 from being pulled out.

In the unlocking position, at least part of the stop protrusion 222 extends into the conversion hole 112, so that the locking protrusion 221 is driven to move in a direction away from the first protrusion 31, the locking protrusion 221 is located on a avoiding path of the first protrusion 31, and a user can smoothly take out the inner drawer 3 from the mounting groove 121.

As shown in fig. 4, according to an embodiment of the present invention, the locking protrusion 221 and the stopping protrusion 222 are disposed in a staggered manner. Thus, the locking piece 2 has better effect of locking the inner drawer 3 and more stable structure. For example, the locking protrusion 221 and the stopper protrusion 222 are disposed offset in the up-down direction.

As shown in fig. 2, according to an embodiment of the present invention, the outer side wall of the inner drawer 3 is provided with a first protrusion 31 and a second protrusion 32, and the first protrusion 31 and the second protrusion 32 define a locking groove 33.

In the locking position, the locking protrusion 221 is fitted in the locking groove 33; in the unlocking position, the locking protrusion 221 is disengaged from the locking groove 33.

In this way, while guaranteeing that the inner drawer 3 has the locking groove 33, a certain gap can be reserved between the inner drawer 3 and the inner wall of the mounting groove 121, so that the inner drawer 3 is prevented from being damaged due to friction when being pulled out from the mounting groove 121, the risk of abrasion of the inner drawer 3 and the movable platform 12 is reduced, and the service life of the drawer assembly is prolonged.

As shown in fig. 7 and 8, according to an embodiment of the present invention, the inner wall of the moving space 111 is further provided with a hovering hole 113, the locking member 2 is further formed with a hovering portion 21, and the position of the hovering hole 113 corresponds to the position of the hovering portion 21 at this time corresponding to the opened state of the mount, and the hovering portion 21 is adapted to pass through the hovering hole 113, so that the moving part is switched between the hovering state and the free state. For convenience of description, when the hovering hole 113 is provided, the open state at this time refers to a state in which the position of the switching hole 112 corresponds to the position of the stopper protrusion 222 and the hovering hole 113 corresponds to the position of the hovering portion 21. Likewise, the closed state refers to a state in which the position of the switching hole 112 does not correspond to the position of the stopper protrusion 222 and the position of the hovering hole 113 does not correspond to the position of the hovering portion 21.

In the hovering state, at least part of the hovering portion 21 is located in the hovering aperture 113 to achieve hovering effect by cooperation between the hovering portion 21 and the hovering aperture 113.

According to an embodiment of the invention, an elastic element is arranged between the moving part and the locking element 2, which elastic element is adapted to bring about, in a hovering state, that at least part of the hovering part 21 protrudes into the hovering hole 113. Therefore, the automatic hovering of the moving part can be realized through the elastic piece, and the structure is simple and convenient.

The locking piece 2 is rotatably installed on the fixing piece 13, the fixing piece 13 is fixed on the outer side wall of the movable platform 12, which is close to the bottom, an installation groove 121 is formed in the movable platform 12, and the inner drawer 3 is detachably arranged in the installation groove 121.

The moving platform 12 is provided with a first through hole 122, and the fixing member 13 is provided with a second through hole 131, and the first through hole 122, the second through hole 131 and the mounting groove 121 are communicated with each other, so that the locking member 2 can be extended or retracted into the mounting groove 121 through the first through hole 122 and the second through hole 131.

The upper half of the locking member 2 forms a hovering portion 21, the lower half of the locking member 2 forms a converting portion 22, the middle of the locking member 2 is hinged to the moving member, the hovering hole 113 is located above the converting hole 112, and the hovering hole 113 and the converting hole 112 are both provided at a portion of the mounting housing 11 near the top end. The switching portion 22 includes a locking protrusion 221 extending toward the inner drawer 3 and a stopper protrusion 222 extending toward the mounting housing 11, the locking protrusion 221 and the stopper protrusion 222 being disposed offset in the up-down direction.

The fixing pieces 13 and the locking pieces 2 are two groups corresponding to each other one by one, the two groups of fixing pieces 13 and the locking pieces 2 are respectively arranged on the left side and the right side of the mobile platform 12, correspondingly, the hovering holes 113 and the converting holes 112 are also two groups corresponding to each other one by one, and the two groups of hovering holes 113 and the converting holes 112 are respectively arranged on the left side and the right side of the installation shell 11.

The left side wall and the right side wall of the inner drawer 3 are respectively provided with a locking groove 33 which corresponds to the two groups of locking pieces 2. Taking the left side wall of the inner drawer 3 as an example, a first protrusion 31 and a second protrusion 32 are arranged on the outer side wall of the inner drawer 3 near the bottom, and the first protrusion 31 and the second protrusion 32 jointly define a locking groove 33.

The specific working process of the drawer component is as follows: the movable platform 12 gradually rises from the bottom of the movable space 111, and as shown in fig. 1 and 2, the locking piece 2 is always defined between the inner wall of the movable space 111 and the outer side wall of the inner drawer 3 until the movable platform 12 reaches the limit position, i.e., the highest point, at which time the inner drawer 3 is locked in the installation groove 121 by the locking protrusion 221 because the stop protrusion 222 is stopped against the inner wall of the movable space 111 and the locking protrusion 221 is locked in the locking groove 33, and the user cannot take out the inner drawer 3.

As shown in fig. 3 and 4, when the moving platform 12 reaches the highest point, the position of the conversion part 22 corresponds to the position of the conversion hole 112, the position of the hovering part 21 corresponds to the hovering hole 113, and at this time, the conversion part 22 has a degree of freedom to move in a direction away from the inner drawer 3, so when the user pulls up the inner drawer 3, as shown in fig. 5 to 8, the inner drawer 3 pushes the conversion part 22 to move in a direction away from the inner drawer 3, and the stopper protrusion 222 protrudes into the conversion hole 112, so that the locking protrusion 221 is disengaged from the locking groove 33, and at this time, the inner drawer 3 can be smoothly taken out from the installation groove 121.

As shown in fig. 5 to 8, during the process that the user withdraws the inner drawer 3 from the mounting groove 121, the inner drawer 3 first pushes the conversion part 22, so that at least part of the conversion part 22 extends into the conversion hole 112, and then the locking member 2 is switched from the locking position to the unlocking position, since the elastic member is in the deformed state at this time, after the drawer 3 is withdrawn, the elastic member applies an elastic force to the locking member 2 in order to restore the original state, the elastic member drives the locking member 2 to move, the hovering part 21 of the locking member 2 moves towards the direction approaching the hovering hole 113 under the action of the elastic force applied by the elastic member, and finally at least part of the hovering part 21 extends into the hovering hole 113 and abuts against the hole wall of the hovering hole 113, so that hovering of the moving member is realized, namely, when the moving member is in the hovering state (i.e. as shown in fig. 7 and 8), and at least part of the conversion part 22 moves towards the mounting groove 121 under the driving of the hovering part 21, and at least part of the conversion part 22 is located in the mounting groove 121. In some specific embodiments, the elastic member is a torsion spring disposed on the rotation shaft of the locking member 2, and in addition, may be an elastic member such as a spring or rubber disposed at other positions between the locking member 2 and the moving member, so long as the locking member 2 can be driven to hover the moving member after the drawer 3 is pulled out.

In one embodiment of the invention, the elastic member is a torsion spring, the torsion spring is sleeved on the rotating shaft, one end of the torsion spring is fixed with the rotating shaft, the other end of the torsion spring is fixedly connected with the locking member 2, in the locking state, the torsion spring is in a deformation state, the torsion spring can apply a force to the hovering part 21 towards the direction of the hovering hole 113, so that after the inner drawer 3 is pulled out, the locking member 2 rotates under the force of the torsion spring, the hovering part 21 moves towards the direction close to the hovering hole 113, and the hovering part 21 can extend into the hovering hole 113. For example, in fig. 8, the locking member 2 is rotated clockwise by the torsion spring so that the hovering portion 21 protrudes into the hovering hole 113.

In another embodiment of the present invention, the elastic member is a spring, which is disposed between the hovering portion 21 and the fixing member 13 and fixedly connected to the hovering portion 21 and the fixing member 13, respectively, and in the locked state, the spring is in a stretched state, and the spring can apply a tensile force to the hovering portion 21 in a direction toward the hovering hole 113, so that after the inner drawer 3 is drawn out, the locking member 2 rotates under the tensile force of the spring, so that the hovering portion 21 moves in a direction approaching the hovering hole 113, and the hovering portion 21 can extend into the hovering hole 113.

As shown in fig. 9 to 12, when the inner drawer 3 is replaced, the first protrusion 31 pushes the locking protrusion 221 to rotate in a direction away from the inner drawer 3, thereby driving the hovering part 21 to be disengaged from the hovering hole 113, and at this time, the moving platform 12 can be lifted freely.

In summary, according to the drawer assembly of the embodiment of the invention, through the cooperation of avoiding with the motion position by the automatic reset structure, external power is not needed, safety protection is realized, the inner drawer 3 can be taken out only when the mobile platform 12 rises to the highest point, the inner drawer 3 can shield the mechanism to prevent foreign matters or hands of a user from entering the lifting mechanism when the mobile platform 12 does not rise to the highest point, and even if the inner drawer 3 is taken out when the mobile platform 12 rises to the highest point, the mobile platform 12 is in a hovering state at this time, and foreign matters or hands of a user can be prevented from entering. Therefore, the safety of the structure can be ensured and the personal safety can be protected on the premise of not increasing extra energy consumption.
