Description

Technical Field

[0001] This utility model relates to the field of cabinet lock technology, specifically to a side latch locking structure for a grounding wire management cabinet. Background Technology

[0002] In power systems, grounding wires are critical safety tools for ensuring personal safety and stable equipment operation. Grounding wires must be stored in designated locations, numbered, and managed, and the operation process must meet the "five preventions" requirements (preventing accidental opening and closing of circuit breakers, opening and closing disconnecting switches under load, hanging grounding wires while energized, energizing with grounding wires connected, and accidentally entering energized compartments). However, the locking structure of traditional grounding wire management cabinets has some problems. During the installation of the lock body, operator errors may result in the gap between the installed lock and the lock body being too large or too small, affecting the normal engagement between the lock and the lock body. Since most existing lock bodies are directly installed on the management cabinet by drilling holes, re-drilling holes would increase the risk of moisture in the management cabinet, affecting its normal operation. Therefore, a side-latch locking structure for grounding wire management cabinets is proposed to solve the above problems. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] The purpose of this utility model is to solve the problem that during the installation of the lock body, operator errors may lead to an excessively large or small gap between the installed lock buckle and the lock body, affecting the normal engagement between the lock buckle and the lock body. However, since most existing lock bodies are directly installed on the management cabinet by drilling holes, re-drilling holes would increase the risk of moisture damage to the management cabinet and affect its normal operation. Therefore, a grounded wire management cabinet side latch locking structure is proposed.

A rotating handle is rotatably connected to the inner side of the fixing plate via a hinge shaft. A rotating shaft is rotatably connected to the inner side of the rotating handle. A U-shaped latch is provided on the rotating shaft. A locking seat is provided at the front end of the base plate. Two limiting plates are fixedly connected to the top of the locking seat. The U-shaped latch is engaged with the two limiting plates. An adjustment mechanism is provided on the U-shaped latch for adjusting the distance between the U-shaped latch and the two limiting plates.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Preferably, the adjusting mechanism includes a U-shaped smooth section, two threaded sections, and four limiting nuts. The inner side of the rotating shaft is threadedly connected to two threaded sections, and the outer sides of the two threaded sections are threadedly connected to the U-shaped smooth section.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the embodiments, by Figure 1 and Figure 2A side latch locking structure for a grounding wire management cabinet is provided, comprising a base plate 1, a fixing plate 2 fixedly connected to the top of the base plate 1, a rotating handle 3 connected to the inner side of the fixing plate 2 via a hinge shaft, a rotating shaft 4 rotatably connected to the inner side of the rotating handle 3, a U-shaped latch 5 provided on the rotating shaft 4, a locking seat 6 provided at the front end of the base plate 1, two limiting plates 7 fixedly connected to the top of the locking seat 6, the U-shaped latch 5 engaging with the two limiting plates 7, and an adjustment mechanism provided on the U-shaped latch 5 for adjusting the distance between the U-shaped latch 5 and the two limiting plates 7.

[0021] With the above setup, the operator manually lifts the handle 3 upwards around the hinge axis on the fixed plate 2. This process requires overcoming the damping effect of the hinge axis connection. The lifted handle 3, through the rotating shaft 4 connected to its inner side, drives the U-shaped latch 5 fixed on the rotating shaft 4 to rotate upwards together. Its movement trajectory is such that the bottom of the U-shaped latch 5 is lifted and passes the top height of the two limiting plates 7 at the top of the lock seat 6. The U-shaped latch 5 falls precisely downwards into the inner side of the two limiting plates 7 of the lock seat 6. The U-shaped latch 5 and the two limiting plates 7 form a tight snap-fit ​​relationship, and the cabinet door is firmly locked. Due to the damping effect, the handle 3 will not rotate without external force. It should be noted that if the distance between the base plate 1 and the lock seat 6 is too large or too small when the operator first installs the base plate 1 and the lock seat 6, the relative distance between the U-shaped latch 5 and the two limiting plates 7 can be adjusted through the adjustment mechanism to ensure that the U-shaped latch 5 can be snapped into the inner side of the two limiting plates 7.

[0022] Reference Figure 1 and Figure 2 The adjusting mechanism includes a U-shaped smooth section 51, two threaded sections 52 and four limiting nuts 53. The inner side of the rotating shaft 4 is threaded with two threaded sections 52, and the outer sides of the two threaded sections 52 are threaded with the U-shaped smooth section 51. The U-shaped smooth section 51 is snapped into the inner side of the two limiting plates 7. The outer sides of the two threaded sections 52 are threaded with two limiting nuts 53, and the two adjacent limiting nuts 53 are in contact with the front and rear ends of the rotating shaft 4 respectively.

[0023] With the above structural setup, the U-shaped smooth section 51 and the two threaded sections 52 form a U-shaped latch 5. When the relative distance between the U-shaped latch 5 and the two limiting plates 7 is too large during installation, rotating the two threaded sections 52 is equivalent to lengthening the U-shaped latch 5, thereby ensuring that the U-shaped latch 5 can be fastened to the inside of the two limiting plates 7. When the relative distance between the U-shaped latch 5 and the two limiting plates 7 is too small during installation, rotating the two threaded sections 52 in the opposite direction is equivalent to shortening the U-shaped latch 5. Finally, the limiting nut 53 is used to clamp the rotating shaft 4 between the two limiting nuts 53 to complete the limiting.

[0024] Reference Figure 1 and Figure 2Among them, both limiting plates 7 are provided with buckle grooves 8, and the U-shaped smooth section 51 is engaged with the inner side of the two buckle grooves 8;

[0025] With the above structural design, the snap-fit ​​groove 8 allows the U-shaped smooth section 51 to snap into the inner side of the snap-fit ​​groove 8, thereby completing the locking.

[0026] Reference Figure 1 and Figure 2 The handle 3 is fixedly connected to the rear end of the handle 9;

[0027] Through the above structural design, the grip 9 can improve operating comfort, effort-saving, controllability and reliability.

[0028] Reference Figure 1 and Figure 2 Both the base plate 1 and the lock seat 6 are provided with several threaded holes 10;

[0029] With the above structural setup, the base plate 1 is firmly installed on the cabinet frame by bolts passing through the threaded holes 10, while the lock seat 6 is rigidly connected to the base plate 1 or moving parts (doors / drawers), ensuring the stability and strength of the entire locking mechanism on the cabinet.
