Description

Technical Field

[0001] The invention relates to an anti-theft panel device for a door. Background Art

[0002] For door locks installed on door panels, the handles are almost always exposed outside the door panels, that is, exposed to the external space accessible to criminals. The handle is exposed to the outside as a whole and is easily damaged by violence such as hammering.

[0003] Currently, the transmission rod of door locks on the market is usually integrated with the handle. Once the handle is damaged, criminals can use the transmission rod to open the lock body, thereby making the door lock lose its anti-theft function. Summary of the invention

[0004] The technical problem solved by the present invention is to provide an anti-theft panel device for a door, which is suitable for anti-theft of door locks.

[0005] In order to achieve the above-mentioned object, the present invention discloses an anti-theft panel device for a door, characterized in that: an anti-theft panel device for a door, characterized in that: it comprises a panel provided with a through hole, a handle passing through the through hole on the panel, and a rotating mechanism connected to the portion of the handle passing through the through hole of the panel;

[0006] The portion of the handle passing through the panel is a handle cavity, and a handle slot is provided on the top of the handle cavity;

[0007] The rotating mechanism comprises a transmission block; a rotating frame which is clamped with the transmission block or fixed by screws, the rotating frame is provided with a rotating frame clamping step, and the rotating frame clamping step is just clamped in the handle clamping groove; and a transmission rod which is clamped in the transmission block, passes through the transmission block, the rotating frame and passes into the handle cavity; a clamping ring which is clamped with the handle is also provided between the rotating frame and the transmission block; the setting of the clamping ring can ensure that the handle is not pulled out from the panel;

[0008] The handle can drive the rotating frame to rotate, and under the action of external force, the locking step of the rotating frame can be sheared from the rotating frame, and the transmission rod does not contact the inner wall of the handle cavity.

[0009] With the above solution, when the handle is normally operated to open and close the door, the rotating frame locking step will not be sheared, but under the action of violence, the rotating frame locking step can be sheared from the rotating frame. The setting of the rotating frame locking step and the feature that the transmission rod does not contact the inner wall of the handle cavity make the handle only rotate idly when violently damaged.

[0010] Preferably, the rotating mechanism further comprises a return torsion spring, and the return torsion spring is sleeved on the outside of the handle cavity, so as to facilitate the return of the handle.

[0011] Preferably, the panel is also provided with two positioning bosses located on the left and right sides above the rotating mechanism; the rotating mechanism also includes a positioning plate, the positioning plate includes a positioning plate boss, and the positioning plate boss is located between the two positioning bosses to ensure that the handle does not rotate 360 ​​degrees.

[0012] Preferably, the positioning plate is located between the rotating frame and the panel.

[0013] Preferably, the portion of the transmission rod passing through the transmission block is a transmission rod through hole, and the transmission rod is clamped in the transmission rod through hole; the transmission rod through hole is a square hole, and the transmission rod is a square rod. The matching arrangement of the square rod and the square hole ensures that the transmission block can drive the transmission rod to rotate.

[0014] Preferably, a spring is provided at the bottom of the handle cavity, and the bottom of the transmission rod rests on the spring.

[0015] Preferably, the through hole is a circular hole, and the handle cavity is a cylindrical cavity.

[0016] The beneficial effect of the present invention is that when an illegal element violently destroys the handle, the locking step of the rotating frame will be sheared off the rotating frame due to the action of violence. Since the transmission rod does not contact the inner wall of the handle cavity, the handle can only rotate idly. No matter how the illegal element rotates the handle, the handle will not drive the rotating mechanism to rotate, thereby ensuring that the lock cannot be illegally opened.

[0023] In the description of the present invention, the terms "upper", "lower", "front" and "back" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0024] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] like Figure 1-6 The figure shows an embodiment of a door anti-theft panel device of the present invention. The door anti-theft panel device includes the following structure:

[0026] 1-handle, 11-handle cavity, 12-handle slot, 13-spring;

[0027] 2-panel, 21-positioning boss, 22-through hole;

[0028] 3-rotation mechanism, 31-transmission rod, 32-transmission block, 321-transmission rod through hole, 33-clamping ring, 34-rotation frame, 341-rotation frame positioning step, 35-positioning plate, 351-positioning plate boss, 36-reset torsion spring.

[0029] In combination with the above, the present invention provides an anti-theft panel device for a door, comprising a handle 1 , a panel 2 and a rotating mechanism 3 .

[0030] The handle 1 and the rotating mechanism are respectively arranged on the outer and inner sides of the panel 2. The panel 2 is provided with a through hole 22. The handle 1 passes through the through hole 22 on the panel 2 and is connected to the rotating mechanism, so that the rotation of the rotating mechanism can be controlled when the handle 1 is pressed down or lifted up. The part of the handle 1 passing through the through hole 22 is the handle 11, and the top of the handle 11 is provided with a handle slot 12.

[0031] In this embodiment, two positioning bosses 21 are further provided on the panel 2, which are respectively located on the left and right sides above the rotating mechanism.

[0032] like Figure 1 As shown, the rotating mechanism includes from top to bottom: a transmission rod 31, a transmission rod 32, a clamping ring 33, a rotating frame 34, a positioning plate 35 and a reset torsion spring 36. The transmission rod 31 is clamped in the transmission block 32. Specifically, the transmission block 32 is provided with a transmission rod through hole 321, and the transmission rod 31 is clamped in the transmission rod through hole 321.

[0033] Further, if Figure 4As shown, after the transmission rod 31 passes through the rotating mechanism 3 and the through hole 22, it passes into the interior of the handle cavity 11, and the transmission rod 31 does not contact the inner wall of the handle cavity 11, and is in an air-avoiding state. A spring 13 is provided at the bottom of the handle cavity 11, and the bottom of the transmission rod 31 abuts against the spring 13. The purpose of setting the spring 13 is to make the panel device adapt to doors of different thicknesses. When the installed door panel is thicker, the elastic deformation of the spring 13 is smaller, so that the part of the transmission rod 31 outside the transmission block 32 is longer to adapt to the thicker door panel. The opposite is true when the door panel is thinner.

[0034] Further, if Figure 4 As shown, the transmission block 32 is connected to the rotating frame 34. In this embodiment, the transmission block 32 and the rotating frame 34 are fixedly connected by screws. When the panel device is in the installation state, the rotating frame 34 is provided with a rotating frame locking step 341, and the rotating frame locking step 341 is just locked in the handle locking groove 12 of the handle 1.

[0035] Furthermore, the collar 33 is disposed between the transmission block 32 and the rotating frame 34. When the panel device is in the installed state, the collar 33 is engaged with the handle 1, stabilizing the connection between the handle 1 and the rotating frame 34, and preventing the handle 1 from being pulled out of the panel 2.

[0036] Furthermore, the positioning plate 35 is disposed between the rotating frame 34 and the panel 2. In this embodiment, the positioning plate 35 is disposed between the rotating frame 34 and the return torsion spring 36, and is sleeved on the outside of the handle cavity 11. The positioning plate 35 includes a positioning plate boss 351, and the positioning plate boss 351 is located between the two positioning bosses 21. When the handle 1 is pressed down or lifted up, the positioning plate 35 will be blocked by the positioning bosses 21 on the panel 2, so that the handle 1 can only rotate between the positioning bosses 21, thereby preventing the handle 1 from rotating 360 degrees.

[0037] Furthermore, the through hole 22 is a circular hole, and the handle cavity is a cylindrical cavity.

[0038] The function of the transmission rod 311 is to connect the lock body door opening device to control the opening and closing of the door lock.

[0039] As a more preferred solution, the rotating frame 34 and the transmission block 32 are connected by snap-fitting.

[0040] When opening the door, the handle 1 is pressed down. Since the handle 1 is connected to the rotating frame locking step 341, the handle 1 can drive the rotating frame 34 to rotate; and since the rotating frame 34 is connected to the rotating block 32, the rotating block 32 is driven to rotate; and then the rotating block 32 drives the transmission rod 31 connected thereto to rotate, and the lock body is opened, thereby achieving door opening. When closing the door, the force on the handle 1 disappears, and the handle 1 returns to its original position under the force of the reset torsion spring 36. In the process of returning to its original position, it drives the rotating mechanism 3 to rotate, thereby achieving door closing.

[0041] When an illegal element violently destroys the handle 1, Figure 6 As shown, the rotating frame locking step 341 will be sheared off from the rotating frame 34 due to the force, and since the transmission rod 31 does not contact the inner wall of the handle 11, no matter how the criminals rotate the handle 1, the handle 1 will not drive the rotating mechanism 3 to rotate, thereby ensuring that the lock cannot be opened illegally.

[0042] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
