The limiting device can be applied to various occasions needing to realize the limiting function, for example, the limiting device can be applied to a hinge assembly but not limited, and the application occasions of the limiting device are not particularly limited.
The hinge assembly of the second aspect of the present invention is exemplified by the limiting device, and the limiting device can be applied to other structures needing to realize the limiting function, such as a sliding assembly, a telescopic assembly, etc., without loss of generality.
It should be noted that the specific definitions and explanations given below for the position-limiting device and its internal structure (including the position-limiting member 3 and the mounting seat) are not influenced by the specific application scenario (e.g., application to a hinge assembly), i.e., the embodiments listed below for the position-limiting device and its internal structure may exist independently of the hinge assembly, and the following descriptions related to the position-limiting device and its internal structure may be regarded as descriptions of the position-limiting device of the first aspect of the present invention.
Before describing the hinge assembly according to the second aspect of the present invention, first briefly described is an application scenario of the hinge assembly according to the present invention, which may be applied to a locker, for example, to opening and closing a door of the locker; the hinge assembly can also be applied to doors and windows, such as the change of the opening and closing angle of the doors and windows; the hinge assembly may also be applied to other variations in the opening and closing angle between two rotatable members, such as between two relatively rotatable arms. The application of the hinge assembly is not particularly limited, and the hinge assembly can be applied between any two relatively rotatable parts.
As shown in fig. 1 to 3, a hinge assembly according to an embodiment of the second aspect of the present invention includes a hinge base 1, a mount base, and a stopper 3.
The hinge base 1 has a stop surface 11, and the hinge base 1 and the mounting base are rotatably connected. The limiting piece 3 is provided with a limiting part 31, and the limiting piece 3 and the hinge base 1 can rotate relatively to switch between a limiting state and a free state; in the limit state, the stopper portion 31 abuts against the stopper surface 11.
The limiting member 3 is detachably mounted to the mount to be switched between a detached state and a fixed state. In the disassembled state, the limiting member 3 is suitable for moving relative to the mounting seat so as to adjust the relative position between the limiting portion 31 and the stop surface 11; in the fixed state, the limiting member 3 is fixed to the mounting base.
According to the hinge assembly of the embodiment of the utility model, the limiting piece 3 can move relative to the mounting base in a disassembly state, so that a user can adjust the relative position between the limiting part 31 and the stop surface 11, after the adjustment operation is completed, the user can fix the limiting piece 3 to the mounting base again, so that the limiting piece 3 is locked relative to the mounting base, and after the adjustment operation and the fixing operation are completed, the limit opening and closing angle of the hinge assembly is changed, namely the limit opening and closing angle of the hinge assembly can be adjusted. Use the hinge subassembly to be applied to the locker as an example, the regulation of the biggest angle of opening the door of locker can be realized to the hinge subassembly to adapt to different locker locating positions, avoid the locker to lead to the door body to collide with the wall body easily because of the biggest angle of opening the door is too big, solved the collision problem of opening the door, and simple structure, cost are lower.
According to the embodiment of the present invention, the above-mentioned "free state" refers to a state when the hinge base 1 and the mounting base can rotate freely, that is, the opening and closing angle of the hinge assembly can be changed freely without reaching the limit opening and closing angle. The "limit state" refers to a state in which the hinge base 1 and the mounting base cannot rotate continuously in a certain direction, that is, the opening and closing angle of the hinge assembly reaches a limit opening and closing angle.
As shown in fig. 1, the hinge assembly switches between the limit member 3 and the free state by the engagement between the stop surface 11 and the limit portion 31, and the engagement between the stop surface 11 and the limit portion 31 is determined by the relative rotation between the limit member 3 and the hinge base 1. Specifically, if the mounting base rotates along a certain direction relative to the hinge base 1, in a fixed state, the mounting base drives the limiting member 3 fixed to the mounting base to rotate, so that the limiting member 3 rotates along the direction relative to the hinge base 1, when the limiting member 3 rotates to a limit state, because the limiting portion 31 is stopped by the stop surface 11, the limiting member 3 cannot rotate continuously along the same direction, and at this time, the hinge assembly reaches a limit opening and closing angle; when the limiting member 3 rotates to the free state, since the limiting portion 31 is not stopped by the stopping surface 11, the limiting member 3 can continue to rotate in the same direction and in the opposite direction, and at this time, the hinge assembly does not reach the limit opening and closing angle.
The limiting part 31 may be a limiting protrusion, a limiting rod, etc., and the utility model is not limited herein as long as the limiting part 31 can perform a limiting function.
According to an embodiment of the present invention, the "detached state" refers to a state in which the limiting member 3 can move relative to the mounting base, and at this time, the limiting member 3 can be partially detached relative to the mounting base (i.e., the limiting member 3 and the mounting base still have a movable connection relationship therebetween), or can be completely detached relative to the mounting base (i.e., the limiting member 3 and the mounting base are completely separated), and the present invention is not limited herein. The "fixed state" refers to a state in which the stopper 3 is fixed to the mount base.
The switch between the fixing state and the disassembling state of the limiting member 3 can be realized by a thread structure, an adhesive structure, a clamping structure and the like, and the connection structure between the limiting member 3 and the mounting base is not particularly limited as long as the limiting member 3 can be detachably mounted on the mounting base.
It should be noted that the free state and the limit state of the limiting member 3 are relative to whether the limiting member 3 and the hinge base 1 can rotate freely, and the detachable state and the fixed state of the limiting member 3 are relative to whether the limiting member 3 and the mounting base can move relatively.
The specific operation of the hinge assembly is described below: in the hinge assembly of the present invention, when a user needs to adjust the limit opening and closing angle of the hinge assembly, the user may release the fixed connection relationship between the limiting member 3 and the mounting base to make the limiting member 3 in the detached state, at this time, the limiting member 3 may move relative to the mounting base, and the user may move the limiting member 3 manually or electrically to drive the limiting portion 31 to move. The limiting member 3 may slide linearly relative to the mounting base or rotate relative to the mounting base, and the utility model is not limited in this respect. It is understood that when the limiting member 3 is linearly slidable relative to the mounting seat, the above-mentioned "relative position between the limiting portion 31 and the stop surface 11" refers to a distance between the limiting portion 31 and the stop surface 11; when the limiting member 3 is rotatable relative to the mounting seat, the above-mentioned "relative position between the limiting portion 31 and the stop surface 11" refers to an included angle between the limiting portion 31 and the stop surface 11.
As shown in fig. 1, taking the limiting member 3 as an example of being rotatable relative to the mounting seat and the hinge assembly applied to the storage cabinet as an example for explanation, in order to realize the adjustment of the maximum door opening angle of the storage cabinet, firstly, the user needs to remove the fixed connection between the limiting member 3 and the mounting seat (i.e. switch the limiting member 3 to the detached state), and then, the user can rotate the limiting member 3 relative to the mounting seat in a manual or electric manner, so as to change the included angle between the limiting portion 31 and the stop surface 11, and since the included angle between the limiting portion 31 and the stop surface 11 changes, the maximum door opening angle of the storage cabinet also changes accordingly. Specifically, when the included angle between the limiting part 31 and the stop surface 11 is reduced, the maximum door opening angle of the storage cabinet is reduced; when the included angle between the limiting part 31 and the stop surface 11 is increased, the maximum door opening angle of the storage cabinet is increased.
For the situation that the limiting member 3 can slide linearly relative to the mounting base, similar to the situation that the limiting member 3 can rotate relative to the mounting base, the present invention is not described herein again.
As shown in fig. 1, according to an embodiment of the present invention, the limiting member 3 is fixed to the mounting base by the fastening bolt 4, the limiting member 3 is provided with a first threaded hole 32, the mounting base is provided with a second threaded hole 21, and in the fixed state, the fastening bolt 4 is respectively fitted in the first threaded hole 32 and the second threaded hole 21.
Like this, can realize the fixed of locating part 3 and dismantle through fastening bolt 4, simple structure, installation and dismantlement are all comparatively convenient to convenience of customers' operation. For example, the user may rotate the fastening bolt 4 to disengage the fastening bolt 4 from the first threaded hole 32 and/or the second threaded hole 21, so that the limiting member 3 is switched to the detached state, wherein the user may disengage the fastening bolt 4 from the first threaded hole 32, may disengage the fastening bolt 4 from the second threaded hole 21, and may also disengage the fastening bolt 4 from both the first threaded hole 32 and the second threaded hole 21; the user can tighten the fastening bolt 4 so that the fastening bolt 4 fits in the first threaded hole 32 and the second threaded hole 21, whereby the stopper 3 is switched to the fixed state.
According to some embodiments of the present invention, in the hinge assembly, the adjustment of different gears of the limit opening and closing angle may be realized by changing the number of the first screw holes 32 and/or the second screw holes 21. Specifically, one or more first threaded holes 32 may be provided, and one or more second threaded holes 21 may be provided. Under the condition that first screw hole 32 and/or second screw hole 21 set up a plurality ofly, the user can cooperate fastening bolt 4 in different first screw hole 32 and second screw hole 21 to the realization is to the regulation of the different gears of limit opening and shutting angle.
In an embodiment of the utility model, the second threaded holes 21 are plural, and the plural second threaded holes 21 are arranged at intervals along the moving direction of the limiting member 3, and/or the plural first threaded holes 32 are arranged at intervals along the moving direction of the limiting member 3.
In this way, if there are a plurality of second threaded holes 21, the user can adjust the limit opening and closing angle by fitting the fastening bolt 4 into different second threaded holes 21; similarly, if the first threaded holes 32 are plural, the user can fit the fastening bolt 4 into different first threaded holes 32 to adjust the limit opening and closing angle.
As shown in fig. 1 and fig. 2, in another embodiment of the present invention, the mounting seat is provided with a plurality of sets of second threaded holes 21 at intervals, the plurality of second threaded holes 21 in the same set are respectively provided at intervals along the moving direction of the limiting member 3, and the plurality of second threaded holes 21 in different sets are provided in a staggered manner.
The limiting member 3 is provided with a plurality of first threaded holes 32 at intervals, and the plurality of first threaded holes 32 correspond to the plurality of groups of second threaded holes 21 one to one.
In this way, it is possible to provide the second threaded hole 21 as much as possible in a limited space, thereby increasing the adjustable gear of the limit opening and closing angle as much as possible. As shown in fig. 2, the mounting seat is provided with two sets of second threaded holes 21, and correspondingly, the limiting member 3 is provided with two first threaded holes 32, wherein one of the first threaded holes 32 corresponds to the position of one set of the second threaded holes 21, and the other one of the first threaded holes 32 corresponds to the position of the other set of the second threaded holes 21.
According to other embodiments of the present invention, in the hinge assembly, the adjustment of different gears of the limit opening and closing angle can also be realized by changing the shape of the first threaded hole 32 and/or the second threaded hole 21. Specifically, at least one of the first threaded hole 32 and the second threaded hole 21 is a long hole extending in the moving direction of the limiting member 3, and the user can fix the fastening bolt 4 at different positions in the long hole to adjust different gears of the limit opening and closing angle.
Of course, the above-mentioned embodiments are only some of the embodiments of the hinge assembly according to the present invention, and the present invention is not particularly limited with respect to the number and specific shape of the first and second screw holes 32 and 21. Note that, the movement direction of the stopper 3 in the above-described "provided at intervals in the movement direction of the stopper 3" means the movement direction of the stopper 3 with respect to the mounting base in the detached state.

Furthermore, the first matching surface and the second matching surface are arc surfaces with corresponding shapes respectively. In this way, the first mating surface and the second mating surface are designed to be arc surfaces adapted to the rotational movement mode, so that the stability of the stopper portion 31 when rotating with respect to the hinge base 1 can be further improved.
Of course, the first mating surface and the second mating surface may also be plane surfaces or curved surfaces with other shapes, and the utility model is not limited thereto.
