DETAILED DESCRIPTION
[0034] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0035] like Figure 1-Figure 3 As shown, a preferred embodiment of the present invention provides a tool cabinet with an interlocking function. The tool cabinet mainly includes a box body 1, an interlocking mechanism, and a plurality of drawers 2. The space within the box body 1 is divided into multiple layers from top to bottom, and each layer is equipped with a drawer 2. Slideways are provided on both sides of each layer to facilitate the sliding and pulling out of the drawers 2. The interlocking mechanism is installed on the back of the drawers 2. When one drawer 2 is pulled out, the other drawers 2 are locked by the interlocking mechanism and cannot be pulled out, thereby preventing the tool cabinet from collapsing due to the center of gravity shifting to one side.
[0036] like Figure 5-Figure 7 As shown, the interlocking mechanism primarily consists of a lock catch 3, a rotating shaft 10, blocks 5, and a self-locking fixing plate 4. A lock catch 3 is mounted on the back of each drawer 2. The self-locking fixing plate 4 is located on the back of the drawer 2 and is vertically fixed to the inside of the box body 1. The rotating shaft 10 is vertically mounted on the self-locking fixing plate 4 and is rotationally connected to the self-locking fixing plate 4. The number of blocks 5 matches the number of locking hooks 9, with the two corresponding one-to-one. The blocks 5 are mounted on the rotating shaft 10, and all blocks 5 rotate synchronously when the rotating shaft 10 rotates.
[0037] like Figure 10 As shown, the lock buckle 3 is composed of three parts: a connecting plate 32, a baffle 31, and a connector 33. The connecting plate 32 is fixed to the back of the drawer 2 by screws. The baffle 31 is arranged vertically. In this embodiment, two connectors 33 are provided on one side of the baffle 31. The two connectors 33 are arranged parallel to each other. The ends of the connectors 33 are integrally connected to the baffle 31 and the connecting plate 32, making the overall shape of the lock buckle 3 present an "L" shape. A rectangular lock hole 601 is formed between the connecting plate 32, the baffle 31, and the two connectors 33. A portion of the block 5 extends into the lock hole 601, blocking the movement path of the baffle 31. In this way, when the drawer 2 is pulled outward, the drawer 2 cannot be pulled outward due to the obstruction of the block 5.
[0038] like Figure 11 、 Figure 12 As shown, in other technical solutions, a connecting member 33 can also be provided, so that the connecting member 33 and the blocking bar 31 have two combination forms, both of which are L-shaped, as long as it is ensured that the block 5 can block the blocking bar 31.
[0039] like Figure 8 、 Figure 9As shown, the self-locking fixing plate 4 is fixed to the inner wall of the box body 1 by screws. The self-locking fixing plate 4 is formed by three bends on a whole plate, so that one side of the self-locking fixing plate 4 protrudes outward. A plurality of avoidance openings 401 are provided from top to bottom on the side of the self-locking fixing plate 4 that protrudes outward, and each avoidance opening 401 is provided with a connecting portion 41, which corresponds one-to-one with the lock buckle 3. The avoidance opening 401 is formed by cutting, and the cut part of the plate is bent toward each other to form the connecting portion 41. The connecting portion 41 is composed of two parallel plates 411, and the stopper 5 is sandwiched between the two plates 411 to limit the upper and lower positions of the stopper 5. There is a through hole 4111 on each plate 411, and the rotating shaft 10 passes through the through hole 4111 of each connecting portion 41 in turn, and the lower end of the rotating shaft 10 is rotatably connected to the box body 1.
[0040] In this embodiment, the rotating shaft 10 is in the shape of a prism, which can be a quadrangular prism, a pentagonal prism, a hexagonal prism..., and has a mounting hole 501 on the stopper 5. The shape of the mounting hole 501 is adapted to the cross-sectional shape of the rotating shaft 10. The rotating shaft 10 passes through the mounting hole 501, so that when the rotating shaft 10 rotates, it can drive all the stoppers 5 to rotate synchronously.
[0041] In other technical solutions, the rotating shaft 10 may also be cylindrical, so that it is only necessary to fasten the stoppers 5 to the rotating shaft 10 to ensure that all the stoppers 5 rotate synchronously when the rotating shaft 10 rotates.
[0042] like Figure 13 As shown, the block 5 is machined from a single piece of plate and has two blocking portions 51. The relative rotation angle between the two blocking portions 51 is 90°, meaning that a 90° rotation of one blocking portion 51 will bring the other blocking portion 51 into position. However, the two blocking portions 51 have different shapes. The block 5 has a notch 502 and a relief groove 503, which are roughly diagonally arranged. The relief groove 503 is N-shaped, and the portions of both blocking portions 51 near the lower ends of the relief groove 503 are partially cut away.
[0043] like Figure 9 As shown, the connection between the two plates 411 of the connecting portion 41 forms the brake portion 402. The shape of the notch 502 on the stopper 5 matches the shape of the brake portion 402. When the stopper 5 rotates counterclockwise, the relief opening 401 on the self-locking fixing plate 4 provides clearance, allowing the stopper 5 to rotate to the desired position. When the stopper 5 rotates to the desired position, the notch 502 abuts against the brake portion 402, limiting further rotation of the stopper 5.
[0044] The outwardly protruding side of the self-locking fixing plate 4 also serves as a brake to limit the rotation angle of the stopper 5. When the stopper 5 rotates clockwise, one side of the stopper 5 is close to the outwardly protruding side of the self-locking fixing plate 4, thereby the stopper 5 cannot continue to rotate.
[0045] The two special structural designs mentioned above limit the stopper 5 to rotate only between 0° and 90°.
[0046] During the rotation of the stopper 5 , the two blocking portions 51 will switch and move into the lock hole 601 one after another, blocking the moving path of the blocking bar 31 on the lock buckle 3 to play a blocking role.
[0047] In other technical solutions, the blocking portion 51 may also be a rod, or a block protruding outward, as long as it can prevent the blocking bar 31 from moving.
[0048] In actual use, when one of the drawers 2 is pulled out, the blocking bar 31 on the lock catch 3 will contact the blocking portion 51 on the block 5 and pull the block 5 to rotate. When the block 5 rotates, it will drive the rotating shaft 10 to rotate synchronously, and then drive the other blocks 5 to rotate synchronously. During the rotation process, the lock catch 3 on the drawer 2 being pulled out will disengage from the block 5 until the drawer 2 is completely pulled out. Because the blocking portions 51 on the other blocks 5 are switched in position during the rotation process, there will always be a blocking portion 51 blocking the movement path of the blocking bar 31 on the lock catch 3, thereby completing the locking of the other drawers 2 that have not been pulled out, and the other drawers 2 cannot be pulled out. In this way, only one drawer 2 can be opened at the same time, and the other drawers 2 cannot be opened and are self-locked.
[0049] When the open drawer 2 is pushed back to its original position, the stop bar 31 presses against the blocking portion 51 on the block 5, causing the block 5 to rotate counterclockwise. The two blocking portions 51 on the block 5 return to their original positions. The other blocks 5 also rotate back to their original positions. At this point, all drawers 2 are in the closed position.
[0050] like Figure 3 、 Figure 4 As shown, to lock all drawers 2, a master lock is installed inside the box body 1. This master lock consists of a locking rod 7, a locking plate 6, and a lock 8. The locking rod 7 is located above the topmost drawer 2. One end of the locking rod 7 is connected to the lock 8, and the other end is rotatably connected to the inner wall of the box body 1. The lock 8 is mounted on the box body 1. By inserting a key into the lock 8 and turning the lock 8, the locking rod 7 rotates.
[0051] The locking plate 6 is also located on the back of the drawers 2. A locking hook 9 is fixedly mounted on the back of each drawer 2. Multiple locking holes 601 are defined in the locking plate 6 from top to bottom. These locking holes 601 are strip-shaped holes that extend vertically. Each locking hole 601 corresponds to a locking hook 9, which is inserted into each locking hole 601. When the locking plate 6 moves upward, the locking hook 9 engages the locking plate 6, preventing the drawers 2 from opening. When the locking plate 6 moves downward, the locking hook 9 disengages from the locking hole 601, allowing the drawers 2 to open normally.
[0052] refer to Figure 4 To control the vertical movement of the locking plate 6, the end of the locking rod 7, away from the lock 8, is bent to form an outwardly protruding protrusion 701. The upper end of the locking plate 6 also has a through-hole 602, into which the protrusion 701 is located. When the locking rod 7 rotates, the protrusion 701 points upward, pushing the locking plate 6 upward and moving it upward. When the protrusion 701 lies flat or points downward, the locking plate 6 returns to its original position under the action of gravity and relocks with the locking hook 9.
[0053] The above technical solutions only reflect the preferred technical solutions of the present utility model. Any changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present utility model and fall within the scope of protection of the present utility model.
