Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of locking hooks, in particular to a floating locking hook structure and a cabinet electronic lock. Background Art
[0002] At present, when processing cabinets on the market, the frame structure needs to be welded, and welding will cause welding deformation, resulting in problems with the electronic locking hook not fitting properly when fixed to the electronic lock. Only gaskets can be added at the bottom of the locking hook to compensate for the distance caused by the deformation. Moreover, although there is a fitting gap between the door panel and the frame, during the use of the cabinet, due to the processing deformation of the frame that cooperates with the door, the gap between the door panel and the frame will become smaller, which may cause dryness. In addition, deformation of the door panel caused by long-term use or human damage may also lead to the situation where the door panel cannot be opened or closed. Currently, ordinary countersunk head screws are commonly used to fix the locking hook on the market, so that the locking hook is firmly fixed on the door panel. As a result, when the locking hook on the door panel cooperates with the electronic lock, it may not be closed or opened. Currently, there is a lack of a design form that allows the frame to open and close smoothly after a small amount of deformation. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a floating locking hook structure that can solve the above technical problems.
[0004] The utility model provides a floating locking hook structure, including a locking hook. The locking hook is fixed on a bracket on the door panel main body through a stepped screw.

[0029] Embodiment 1
[0030] As Figures 1-4 shown, a floating hook structure includes a hook which is fixed on a bracket 301 on a door panel main body 3 by a stepped screw 2. The hook includes a hook body 101 and a fixing plate 102. The hook body 101 is of a D-shaped structure and is fixedly connected to the fixing plate 102. The fixing plate 102 is provided with a fixing hole 1021, and the bracket 301 is provided with a threaded hole. The stepped screw 2 includes a threaded section 201 and a smooth section 202. The threaded section 201 is in cooperation with the threaded hole on the bracket 301, and the diameter of the fixing hole 1021 is larger than the diameter of the smooth section 202. The diameter of the smooth section 202 of the above stepped screw 2 is equal to the diameter of the threaded section 201, or the diameter of the smooth section 202 is larger than the diameter of the threaded section 201. As Figure 4 shown, in this embodiment, the diameter of the smooth section 202 is larger than the diameter of the threaded section 201. The hook body 101 can move up and down in the Figure 1 direction shown, and can move left and right in the Figure 2 direction shown. In the Figure 4Move back and forth in the directions shown. The length L of the stepped screw 2 consists of two lengths L1 and L2. L1 is the length of the smooth section 202, and L2 is the length of the threaded section 201. L = L1 + L2. When the stepped screw is fixed on the door panel body, that is, the thread of the threaded section 201 cooperates with the thread of the bracket 301 on the door panel body 3, so that the smooth section 202 is exposed outside the bracket 301. The locking hook can move on the smooth section 202 of the stepped screw 2. At this time, relative to the electronic lock, the locking hook has a certain movable stroke in the front and back directions. Since the size of the fixing hole 1021 is larger than the diameter of the smooth section 202, relative to the door panel body 3, there is also a certain movable stroke in the up and down and left and right directions. When there is a small amount of deformation during the processing of the frame or the door panel is deformed after long-term use or being damaged artificially and does not fit well with the frame, because the locking hook has a certain movable stroke in the front, back, up, down, left and right directions, the locking hook installed on the door panel body can still cooperate well with the electronic lock.
[0031] Embodiment 2
[0032] As Figures 6-9 shown, a cabinet electronic lock includes the above-mentioned locking hook structure and also includes a lock box 4. One side of the lock box 4 is provided with an opening 5 for the locking hook body 101 to enter. A clamping groove rod 6 hinged to its inner wall is arranged in the lock box 4. A torsion spring 7 for resetting is arranged at the hinged part of the clamping groove rod 6 (the initial state of the clamping groove rod 6 is that its clamping groove faces the outside of the opening 5, as Figure 6 shown), the clamping groove on the clamping groove rod 6 is located at the opening 5, and a limiting device for restricting its rotation is arranged above the clamping groove rod 6.
[0033] The limiting device includes a box body 8. A moving rod 9 is slidably connected in the box body. A baffle 10 is fixedly connected to the bottom of the moving rod 9. A spring 11 is arranged on the baffle 10. The spring 11 is sleeved outside the moving rod 9. The top end of the spring 11 is connected to the inner wall of the box body 8. A cross bar 12 is hinged to the top of the moving rod 9. A moving groove 13 is arranged in the middle of the cross bar 12. The moving groove 13 is in a capsule-like structure. A cylinder 14 is movably connected in the moving groove 13. The cylinder 14 is fixedly connected to the inner wall of the lock box 4. One end of the cross bar 12 away from the moving rod 9 is hinged to a limiting rod 15. A limiting block 16 is arranged on one side of the limiting rod 15. The limiting block 16 makes the limiting rod 15 can only rotate towards the left.
[0034] The upper part of the moving rod 9 is provided with a lifting rod mechanism that enables it to move upward. The lifting rod mechanism is a switchable electromagnet 17. The moving rod 9 is made of iron material, and the cross bar 12 is made of plastic material. The switchable electromagnet is an existing structure. Its specific working principle can refer to the electromagnetic door closer. When the electromagnet 17 is in the working state, it attracts the moving rod 9 to approach the electromagnet 17. When the electromagnet 17 is in the non-working state, the spring 11 in the compressed state releases the elastic force, and the moving rod 9 moves downward. One end of the cross bar 12 is tilted, driving the limit rod 15 to rise, so that the slot rod 6 will not be limited, and the lock hook body 101 can be taken out at the opening 5 position. When the electromagnet 17 is switched to the non-working state by setting the door opening button (resuming the working state after a few seconds). If the door panel body 3 is not pulled after clicking the door opening button, the electromagnet 17 will suck up the moving rod 9 again, and the moving rod 9 moves upward. One end of the cross bar 12 drops, driving the limit rod 15 to drop, so that the slot rod 6 will be limited again.
[0035] Working and use process:
[0036] When the lock hook body 101 is inserted into the opening 5, it pushes the slot rod 6 to rotate, and the arc-shaped end of the slot rod 6 rotates counterclockwise. Figure 7 As shown, after contacting the limit rod 15 and continuing to rotate, when the lock hook body 101 is fully extended into the opening 5, the arc-shaped end of the slot rod 6 passes over the limit rod 15, and the limit rod 15 points downward again under the action of gravity. At this time, if the door panel body is pulled to make the lock hook body 101 disengage from the opening 5, the slot rod 6 needs to be rotated clockwise. Due to the existence of the limit rod 15, the rotation of the slot rod 6 is restricted, so that the lock hook body 101 is in a locked state.
[0037] After clicking the door opening button, the electromagnet 17 is temporarily in a non-working state, and the spring 11 in a compressed state releases its elastic force, the moving rod 9 moves downward, and one end of the cross bar 12 is tilted, driving the limit rod 15 to rise, so that the slot rod 6 will not be limited, and the door panel body 3 is pulled, and the lock hook body 101 can be taken out at the opening 5 position. If the elastic force of the torsion spring 7 is relatively large, the lock hook body 101 can also be directly popped out. If the door panel body 3 is not continued to be pulled after clicking the door opening button, the electromagnet 17 will resume its working state after a few seconds, and the moving rod 9 will be sucked up again. The moving rod 9 moves upward, and one end of the cross bar 12 drops, driving the limit rod 15 to drop, so that the slot rod 6 will be limited again, and the lock hook body 101 will be locked again.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
