Description

Technical Field

[0001] This utility model relates to the field of locking mechanism technology, and in particular to a tool cabinet lock linkage structure. Background Technology

[0002] As the name suggests, a tool cabinet is a cabinet for storing tools. Tool cabinets usually have drawers for storing tools.

[0003] Most tool cabinets in this field are currently lockless. Although a very small number are lockable, each drawer on them is locked, requiring each drawer to be unlocked individually to access tools. This is cumbersome, and the fact that each drawer has a lock increases costs. Utility Model Content

[0004] This utility model relates to a tool cabinet lock linkage structure, which solves the problem that most tool cabinets in the field do not have locks. Although a very small number of them do have locks, each drawer has its own lock. When opening the drawers to take out tools, each drawer needs to be unlocked one by one, which is cumbersome and increases costs due to the fact that each drawer has its own lock.

[0005] This utility model provides a tool cabinet lock linkage structure, specifically including: a tool cabinet body; a sliding seat is fixed to the left and right end faces of the inner wall of the tool cabinet body by screws, and a slide rail slides in the sliding seat, the slide rail is fixed to the left and right sides of the drawer; a limiting plate is fixed to the left and right end faces of the inner wall of the tool cabinet body by screws, and two locking rod limiting plates slide on each limiting plate. The two locking rod limiting plates on the left are welded to a sliding rail locking rod on the left, and the two locking rod limiting plates on the right are welded to a sliding rail locking rod on the right. The locking rod limiting plates can slide up and down on the limiting plates; seven travel limiting holes are opened on each limiting plate, and seven locking rods are welded to each sliding rail locking rod. The seven locking rods on the left slide in the seven travel limiting holes on the left, and the seven locking rods on the right slide in the seven travel limiting holes on the right. When the sliding rail locking rod moves upward, the locking rod contacts the front end face of the sliding rail. At this time, the sliding rail is in a forward and backward movement limiting state.

[0006] Furthermore, the left and right ends of the tool cabinet body are provided with side tool slots in a linear array.

[0007] Furthermore, two linkage rod limiting components are fixed inside the main body of the tool cabinet. Each linkage rod limiting component has a rotating linkage rod. The outer sides of the two linkage rods are respectively inserted into two slide rail locking rods. The width of the linkage rod insertion hole on the slide rail locking rod is greater than the width of the linkage rod.

[0008] Furthermore, a door lock is installed on the main body of the tool cabinet, and a rotating tongue is mounted on the door lock. The inner ends of the two linkage rods are both sleeved on the rotating tongue, and the sleeve holes of the linkage rods on the rotating tongue are larger than the outer contour of the rotating tongue.

[0009] Furthermore, a rectangular block structure is welded onto one of the linkage rods on the left. When the rotating tongue rotates 90 degrees, the block is in a compressed state. At this time, the inner end of the two linkage rods moves downward and the outer end of the two linkage rods tilts upward.

[0010] Furthermore, the tool cabinet body has a rotating cover plate, and two gas springs also rotate on the tool cabinet body. The two gas springs rotate on the cover plate through connecting pins. A locking plate is fixed on the rotating tongue, and the locking plate matches the locking bolt on the cover plate. The limiting plate, slide rail locking rod, locking rod limiting plate, travel limiting hole, linkage rod limiting component, linkage rod, door lock, rotating tongue, locking plate, locking rod and force block together form the locking assembly.

[0011] This utility model provides a tool cabinet lock linkage structure, which has the following beneficial effects:

[0012] In terms of tool storage, the tool cabinet features linear arrays of tool slots on the left and right sides, which greatly facilitates the placement of various tools, effectively utilizes space, and achieves orderly tool placement.

[0013] In terms of drawer and slide rail design, the sliding base works in conjunction with the slide rail to ensure smooth drawer movement. Meanwhile, a unique locking mechanism plays a crucial role. When the key is turned, the latch rotates 90 degrees, pressing the linkage rod and causing the slide rail locking rod to move upwards. This brings the locking rod into contact with the front surface of the slide rail, limiting its forward and backward movement and effectively preventing the drawer from accidentally sliding out, thus enhancing safety.

[0014] The design of components such as the linkage limiter and the linkage rod itself is ingenious. The linkage limiter ensures that the linkage rod can rotate flexibly, and the design of the insertion hole width on the slide rail lock rod and the sleeve hole design on the rotating tongue of the linkage rod provides ample space for the angular rotation of the linkage rod, ensuring smooth operation of the entire locking action.

[0015] In terms of overall protection, the cover plate of the tool cabinet, which rotates to connect with the main body, works with a gas spring for easy opening and closing. Furthermore, the locking plate on the rotating tongue matches the locking bolt on the cover plate, effectively locking the cover while simultaneously locking the drawer, providing all-around protection for the tools inside the cabinet and preventing loss or damage.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1: Please refer to Figures 1 to 6 :

[0029] This utility model proposes a tool cabinet lock linkage structure, including: a tool cabinet body 1; a sliding seat is fixed to the left and right end faces of the inner wall of the tool cabinet body 1 by screws, and a slide rail 2 slides in the sliding seat, the slide rail 2 being fixed to the left and right sides of the drawer 201; a limiting plate 301 is fixed to the left and right end faces of the inner wall of the tool cabinet body 1 by screws, and two locking rod limiting plates 303 slide on each limiting plate 301, the two locking rod limiting plates 303 on the left are welded to a left slide rail locking rod 302, and the two locking rod limiting plates 303 on the right are welded to the left slide rail locking rod 302. 3 is welded to a slide rail locking rod 302 on the right side. The locking rod limiting plate 303 can slide up and down on the limiting plate 301. Each limiting plate 301 has seven stroke limiting holes 304. Each slide rail locking rod 302 has seven locking rods 310 welded on it. The seven locking rods 310 on the left slide in the seven stroke limiting holes 304 on the left, and the seven locking rods 310 on the right slide in the seven stroke limiting holes 304 on the right. When the slide rail locking rod 302 moves upward, the locking rods 310 contact the front end face of the slide rail 2. At this time, the slide rail 2 is in a forward and backward movement limiting state.

[0030] The tool cabinet body 1 has side tool slots 101 arranged in a linear array on both the left and right ends. When in use, tools can be inserted into the side tool slots 101, which facilitates the placement of tools.

[0031] The tool cabinet body 1 has two linkage rod limiting parts 305 fixed inside. Each linkage rod limiting part 305 has a rotatable linkage rod 306. The outer sides of the two linkage rods 306 are respectively inserted into two slide rail locking rods 302. The width of the insertion hole provided on the slide rail locking rod 302 for the linkage rod 306 is greater than the width of the linkage rod 306, ensuring that the linkage rod 306 has enough space when rotating at an angle.

[0032] The tool cabinet body 1 is equipped with a door lock 307, and a rotating tongue 308 is mounted on the door lock 307. The inner ends of the two linkage rods 306 are sleeved on the rotating tongue 308, and the sleeve holes of the linkage rods 306 on the rotating tongue 308 are larger than the outer contour of the rotating tongue 308.

[0033] One of the linkage rods 306 on the left side has a rectangular block-shaped force-bearing block 311 welded on it. When the rotating tongue 308 rotates 90 degrees, the force-bearing block 311 is in a compressed state. At this time, the inner end of the two linkage rods 306 moves downward and the outer end of the two linkage rods 306 tilts upward. During use, when the key is inserted and rotated 90 degrees, the rotating tongue 308 rotates 90 degrees. Under the compression of the rotating tongue 308, the inner end of the two linkage rods 306 moves downward, and at the same time, the outer end of the two linkage rods 306 tilts upward. The tilting of the outer end of the two linkage rods 306 can drive the two slide rail locking rods 302 to move upward. At this time, the locking rods 310 on the left and right sides can lock the slide rail 2.

[0034] Example 2, based on Example 1, such as Figures 1 to 6 As shown, a cover plate 103 rotates on the main body 1 of the tool cabinet, and two gas springs 102 also rotate on the main body 1 of the tool cabinet. The two gas springs 102 rotate on the cover plate 103 through connecting pins. A locking plate 309 is fixed on the rotating tongue 308, and the locking plate 309 matches the bolt on the cover plate 103. The limiting plate 301, the slide rail locking rod 302, the locking rod limiting plate 303, the travel limiting hole 304, the linkage rod limiting part 305, the linkage rod 306, the door lock 307, the rotating tongue 308, the locking plate 309, the locking rod 310, and the force block 311 together form the locking assembly 3. When the rotating tongue 308 is rotated by the key, the locking plate 309 engages with the bolt on the cover plate 103 to lock the cover plate 103.

[0035] The working principle of this embodiment is as follows: Insert the key and turn it 90 degrees. At this time, the rotating tongue 308 rotates 90 degrees. Under the pressure of the rotating tongue 308, the inner end of the two linkage rods 306 moves downward, while the outer end of the two linkage rods 306 tilts upward. The tilting of the outer end of the two linkage rods 306 can drive the two slide rail locking rods 302 to move upward. At this time, the locking rods 310 on the left and right sides can lock the slide rail 2. At the same time, when the rotating tongue 308 is rotated by the key, the locking plate 309 engages with the bolt on the cover plate 103 to lock the cover plate 103. When placing tools, in addition to placing the tools in the drawer 201, the tools can also be inserted into the side tool slot 101.
