Referring to fig. 1, a locking device 100 according to the present invention is shown. The locking device 100 includes: a base 110, a locking member 120, a positioning member 130, and a trigger 140. The locking member 120 is mounted to the base 110 and is movable between a locking position and a non-locking position. The positioning member 130 is movably mounted to the locking member 120 and is movable between two positions, in one of which the positioning member 130 is blocked by a stop member 112 (see below) on the base 110 when the locking member 120 moves toward the locking position; and in another position, the locking member 120 can be moved toward the locked position. The trigger 140 is capable of moving the positioning member 130 from one position to another.

Specifically, the base 110 is provided with a stopper 112. In the particular embodiment shown, the base 110 has a generally rectangular base plate portion 111, with a stop 112 extending downwardly from a lower surface of the base plate portion 111. However, it should be understood that the shape of the substrate portion 111 may be arbitrarily set as required, and is not limited to the above shape. In the illustrated embodiment, the stopper 112 is a hanging table extending downward from the base plate portion 111 in the vicinity of the front end of the base plate portion 111 (see fig. 5). An opening 1111 is provided in the substrate portion 111, and the lock member 120 located below the base 110 is accessible through the opening 1111. A groove portion 1112 is also provided around the opening 1111 on the upper surface of the substrate portion 111 for guiding the corresponding portion of the locking member 120 to move relative to the base 110. In the illustrated embodiment, groove portion 1112 is provided at a front side of opening 1111, but it should be understood that the present invention is not limited thereto.

Referring to fig. 6-8, the locking member 120 is mounted to the base 110 and moves between a locked position and an unlocked position relative to the base 110. Fig. 6 shows the locking member 120 in the unlocked position, while fig. 7 shows the locking member 120 in the locked position. In the illustrated embodiment, the locking member 120 is disposed adjacent to the base 110 below the base 110. The locking member 120 includes a body portion 121. In the illustrated embodiment, the body portion 121 has a substantially rectangular parallelepiped shape. It should be understood that the shape of the body portion 121 may be arbitrarily set as required and is not limited to the above-described shape. A base engaging portion 124 extending upward and forward is provided at an upper surface of the main body portion 121. In the illustrated embodiment, base engagement portion 124 is in the shape of a thin plate and smaller than the size of opening 1111 and is engageable with groove portion 1112 around opening 1111 through opening 1111 in base 110, whereby lock member 120 can slide in and out relative to base 110 due to the guidance of base engagement portion 124 by groove portion 1112 to switch between the lock position and the unlock position. Further, it is also conceivable that the base engagement portion 124 is provided at the upper surface of the main body portion 121 with an upward and rearward extension, and accordingly, the groove portion 1112 is located at the rear side of the opening 1111.

When the locking member 120 moves forward to the locking position, the base engagement portion 124 moves to the front position within the groove portion 1112. More preferably, in order to facilitate the determination that the locking member 120 has been moved to the locking position relative to the base 110, complementary concave-convex structures are provided on the surfaces of the base engaging portion 124 and the groove portion 1112 that are opposite to each other, and when the locking member 120 is moved to the locking position, the complementary concave-convex structures on the base engaging portion 124 and the groove portion 1112 are engaged with each other and generate a click sound, whereby the operator can determine that the locking member 120 has been completely moved to the locking position. In addition, a cavity 123 is preferably provided in the upper surface of the base engaging portion 124 to facilitate the operator's finger operation of the locking member 120 to serve as a pull handle for moving from the locked position to the unlocked position, for example.

The body part 121 is further provided with a latch bolt 122 extending forward from the lower end of the body part 121. When the lock 120 is in the locked position, the locking tongue 122 extends into a corresponding locking hole 240 in the catch box enclosure 220 (see fig. 11). Further, a first biasing device 150 is provided between the body portion 121 and the base 110 to bias the locking member 120 toward the locking position. In the illustrated embodiment, two blind holes 125 are also provided on the rear side surface of the body portion 121 (see fig. 2 a). Accordingly, an end wall 113 extending downward from the base plate portion 111 is provided near the rear end of the base 110, and two bosses 114 are provided on the front side surface of the end wall 113 (see fig. 7). Both ends of the first biasing means 150, such as a compression spring, are confined within the blind hole 125 and outside the boss 114, respectively, to apply a forward pushing force to the locking member 120. It should be understood, however, that the number of blind holes 125 and bosses 114 is not limited to two, but may be provided in any suitable number as desired. Instead of the blind hole, a boss may be provided on the rear side surface of the body portion 121. Likewise, instead of the boss, a blind hole may be provided on the front side surface of the end wall 113. Further, the first biasing means 150 may also be provided, for example, between the end wall 113 and the rear end face of the base engaging portion 124 to apply a forward urging force to the locking member 120. Further, it is also conceivable to provide, for example, an elastic rib between the front end of the base 110 and the front end of the body portion 121 to apply a forward pulling force to the locking piece 120, thereby achieving biasing toward the locking position.

As shown in fig. 2a and 2b, a cavity 126 is also provided on the bottom surface of the body portion 121. The cavity 126 extends in the front-to-rear direction. A retainer 130 is mounted within the pocket 126. The positioning member 130 is rotatably coupled to the locking member 120. In the illustrated embodiment, the positioning member 130 is a rod-like structure that is positioned within the cavity 126 and pivotally connected to the locking member 120. The front end surface of the positioning member 130 is a positioning plane 132. Specifically, the positioning member 130 is pivotally connected by a pivot pin 131. The pivot pin 131 accomplishes this pivotal connection through a transversely extending through pin hole in the retainer 130 and a blind pin hole in the longitudinally opposite wall of the cavity 126.

The positioning member 130 is provided with a second biasing means 160 located between the positioning member 130 and the top wall of the cavity 126 at a location rearward (i.e., rearward, or first end) of the pivot pin 131. Specifically, as shown in fig. 6,

grooves

1261 and 134 are provided at corresponding positions on the top wall of the cavity 126 and the upper surface of the positioning member 130, respectively, to restrict both ends of the second biasing means 160, such as a tower spring, respectively. The second biasing device 160 applies a biasing force to the positioning member 130 to deflect the front end (i.e., the second end) of the positioning member 130 upward. It should be understood that other resilient means may be provided so long as a biasing force can be applied to the positioning member 130 to bias it toward the stop position. The position of the second biasing device 160 is not limited to the above embodiments, but can be disposed at any suitable position between the positioning member 130 and the locking member 120. In addition, in order to ensure that the front end of the positioning member 130 can move to the stopping position abutting against the stopper 112 by the second biasing device 160 and can smoothly move to the locking position after the stopper 112 is separated, the positioning member 130 has a bent rod shape, and a section of the positioning member 130 between the locking shaft and the front end is bent upward with respect to a section between the locking shaft and the rear end.

In the above embodiment, the positioning member 130 is made of a rigid material. In another embodiment, at least a portion of the positioning member 130 is made of an elastic material, such as an elastic rubber; or for example, the positioning member 130 is made of metal, and a portion of the positioning member 130 is a leaf spring structure, such that when the locking member 120 is in the unlocked state, the front end of the positioning member 130 is deflected upward to the stopping position. In this case, a separate biasing means such as a separate tower spring may not be provided.

When the locking member 120 is held in the unlocked position against the force of the first biasing means 150, the positioning member 130 can be rotated by the biasing force of the second biasing means 160 to a stop position in which the positioning member 130 engages the stop member 112 to prevent the locking member 120 from moving toward the locked position, thereby positioning the locking member 120 in the unlocked position. When the forward end of the positioning member 130 is deflected downwardly against the second biasing means, the positioning member 130 is in a free position, in which the positioning member 130 is disengaged from the stopper 112, so that the locking member 120 can move freely relative to the base 110. When the positioning member 130 is in the stop position, the positioning member 130 abuts against the stop member 112, such as a hanging stand, thereby preventing the locking member 120 from moving toward the locking position due to the first biasing means 150. In the illustrated embodiment, the second biasing device 160 is a tower spring disposed between the positioning member 130 and the locking member 120.

The locking device 100 also includes a trigger 140. The trigger 140 is movably coupled to the base 110 and is movable relative to the base 110 to urge the positioning member 130 away from engagement with the stop 112. Specifically, in the illustrated embodiment, as shown in fig. 5-7, the trigger 140 is pivotally coupled to the base 110, and specifically to the lower surface of the base 110 on the front side of the stop 112. Both sides of the trigger 140 are pivotally connected to the base 110 by pivot pins 142. The trigger 140 is also provided with a guide slope 115 at one end.

Preferably, a third biasing device 170 is also provided between the trigger 140 and the base 110 to bias the trigger 140 toward the initial position. In this embodiment, a torsion spring 170 is sleeved on one or both of the pivot pins. The rear end portion of the trigger 140 at the pivot pin 142 is referred to as a trigger block 143. In addition, in order to enable the trigger base 143 of the trigger 140 to move away from the stop 112 during rotation, a through hole 141 is provided in the trigger 140, and the through hole 141 may be fitted over the stop 112, for example, of a hanging base, so as not to be blocked by the stop 112 during rotation of the trigger 140. It should be understood that the avoidance between the trigger 140 and the hangar can be accomplished by other avoidance configurations. For example, the central portion of the hanging table may be provided with a through-passage in the front-rear direction, through which the triggering table 143 of the triggering member 140 may extend and be able to rotate therein, thereby avoiding the hanging table.

In the initial position, the trigger base 143 of the trigger 140 abuts the lower surface of the base 110. And when an upward force is applied to the front end of the trigger 140, the trigger stage 143 of the trigger 140 moves downward, thereby pushing the front end of the positioning member 130 away from the stopper 112. Thereby, the locking member 120 can move toward the locking position. At this time, the locking of the locking device 100 is achieved.

Further, it is also contemplated that the trigger 140 may also be slidably connected to the locking member 120 back and forth. In this case, the trigger 140 may be provided at both sides with coupling pins, and the lower surface of the base 110 is provided with bosses extending in the front-rear direction, and opposite surfaces of the bosses are provided with sliding grooves to receive the coupling pins of the trigger 140, thereby achieving the sliding coupling of the trigger 140. The front and rear ends of the trigger 140 are tapered. Wherein the middle part of the hanging table is provided with a through channel in the front-back direction for the trigger 140 to pass through. Thus, when the trigger 140 moves backward, the positioning plane 132 of the positioning member 130 can be pushed away from the hanging table and thus from the stopping position.

As shown in fig. 9-11, the locking device 100 according to the present invention is installed in the corresponding opening 211 of the cover 210 when the locking device 100 is applied to the card cage 200. The card cage 200 further includes a base 230 and a shroud 220 extending upwardly from the base 230 and connected to one another in series. A locking hole 240 is provided near the upper edge 2201 of the enclosure 220. When the cover 210 is mounted to the enclosure 220, the locking tabs 122 of the locking members 120 of the locking device 100 can extend into the locking apertures 240 in the locked position, thereby locking the cover 210 to the enclosure 220.

The installation of the lock device 100 in the cover 210 is shown in detail a in figure 11, in an enlarged view. The cover 210 includes a top panel 212 and a peripheral edge 213 extending downwardly from the periphery of the top panel 212. When the cover 210 is in place on the enclosure 220, the perimeter 213 fits over the enclosure 220. After the locking device 100 is installed in place within the lid 210, the front side of the locking device 100 faces the periphery of the lid 210 and the back side faces the center of the lid 210, and the trigger 140 is positioned proximate the perimeter 213 so that the upper edge of the perimeter 220 can act on the front end of the trigger 140 during placement of the lid 210 on the perimeter 220.

As shown in fig. 11, before the cover 210 is placed on the enclosure 220 to close the enclosure box 200, an operator operates, for example, the groove portion 1112 of the base engaging portion 124 through the opening 1111 of the base 110 to overcome the biasing force of the first biasing device 150 to move the locking member 120 to the unlocking position relative to the base 110, at which the trigger 140 is in the initial position, and the positioning member 130 is in the stopping position under the action of the second biasing device 160, i.e., the positioning plane 132 thereof abuts against the stopper 112, preventing the locking member 120 from moving toward the locking position.

As shown in fig. 12, in the process of placing the cover 210 on the enclosure 220, the upper edge of the enclosure 220 pushes up the front end of the trigger 140, so that the trigger 140 rotates, and the trigger stage 143 of the trigger 140 pushes down the front end of the positioning member 130. As shown in fig. 13, when the cover 210 is in place on the enclosure 220, the front end of the retainer 130 disengages from the stop 112. At this time, since the front end of the positioning member 130 can avoid the stopper 112, the locking member 120 moves forward under the action of the first biasing device 150, so that the locking tongue 122 is inserted into the locking hole 240, thereby locking the box cover 210 and the enclosure 220.

As shown in fig. 14, when it is desired to remove the cover 210 from the enclosure 220, an operator operates, for example, the recessed portion 1112 of the base engaging portion 124 through the opening 1111 of the base 110 to overcome the biasing force of the first biasing device 150 to move the locking member 120 to the unlocked position relative to the base 110, at which time the positioning member 130 enters the stop position under the action of the second biasing device 160 due to the trigger 140 being in the trigger position, such that the positioning plane 132 thereof abuts the trigger table 143 of the trigger 140 to prevent the locking member 120 from moving toward the locked position, thereby fixing the locking device 100 in the unlocked position. In practice, a single operator may sequentially secure each locking device 100 on the cover 210 in the unlocked position to remove the cover 210. In fig. 14, the locking device 100 on one side of the cover 210 is shown secured in an unlocked position while the locking device 100 on the other side of the cover 210 is shown in a locked position. In fig. 15, the locking devices 100 on both sides of the cover 210 are positioned in the unlocked position.

As shown in fig. 16, after the cover 210 is removed, the trigger 140 is reset to the initial position by the third biasing device 170, and the locking member 120 and the positioning member 130 are correspondingly moved forward until the positioning plane 132 of the positioning member 130 abuts against the stop member 112.

Use according to the utility model discloses a locking device can conveniently be carried out the unblock in proper order by a plurality of locking device of single operating personnel on to the cardboard case lid to the price case lid is removed.

The preferred embodiments of the present invention have been described in detail, but it should be understood that various changes and modifications of the invention can be made by those skilled in the art after reading the above teaching of the present invention.
