Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1 - Figure 5 As shown, a burglarproof reinforced lever handle lock includes a lock cylinder 1, which is installed on the door. Panels 2 are provided on both sides of the door, and the panels 2 are connected to each other by mounting bolts 5.

[0027] It also includes:

[0028] Protective panel assembly 4 is installed on the door;

[0029] Locking plate 6 is slidably mounted on protective plate assembly 4. The locking plate 6 is moved by mounting bolts 5, so that protective plate assembly 4 is connected to panel 2.

[0030] The protective plate assembly 4 includes a protective plate 41, which is installed on both sides of the door. The panel 2 is installed on one side of the protective plate 41. A female sleeve 43 is installed on one of the protective plates 41, and a male sleeve 42 is installed through the other protective plate 41. The male sleeve 42 is threadedly connected to the female sleeve 43. The protective plate 41 is firmly installed on the door, providing additional protection for the key parts of the door and preventing criminals from damaging the panel 2 and directly damaging the door body, thereby damaging the lock cylinder 1.

[0031] The protective plate 41 has a through hole through which the mounting bolt 5 passes. The protective plate 41 has a sliding groove 61 on both sides of the through hole. The locking plate 6 is slidably disposed in the sliding groove 61. A reset plate 62 is disposed on the sliding groove 61. A spring 63 is disposed between the reset plate 62 and the locking plate 6. After the mounting bolt 5 is removed, it can automatically reset, which facilitates subsequent installation and maintenance and makes it easy for the mounting bolt 5 to pass through. At the same time, the sliding groove 61 on both sides of the through hole provides a track for the sliding of the locking plate 6, so that the connection between the protective plate assembly 4 and the panel 2 can be realized.

[0032] The locking plate 6 has an inclined surface facing the mounting bolt 5. The mounting bolt 5 can be pressed against the locking plate 6 by the inclined surface, and can slide along the slide groove 61 of the guard plate 41 under the pressure of the mounting bolt 5, thereby realizing the connection with the limiting platform 21 on the panel 2. This effectively increases the connection points between the door and the panel 2 and greatly strengthens the connection strength between the door and the panel 2. One of the inner surfaces of the panel 2 is provided with a mounting nut 51, which is threadedly connected to the mounting bolt 5.

[0033] A limiting platform 21 is provided on the panel 2, and the locking plate 6 is connected to the panel 2 through the limiting platform 21. A connecting post 22 is provided on the panel 2, and the handle head 3 is rotatably mounted on the panel 2. A torsion spring 8 is connected to the connecting post 22 to realize the normal rotation function of the handle. At the same time, the torsion spring 8 can provide a certain rebound force so that the handle head 3 can automatically reset after operation.

[0034] A slot is provided on the handle head 3, and a limiting plate 7 is fitted on the handle head 3. A locking block 72 is provided on the limiting plate 7. The locking block 72 is embedded in the slot and cooperates with the locking block 72 on the limiting plate 7 to ensure synchronous rotation between the handle head 3 and the limiting plate 7, and to provide a basis for limiting the rotation angle of the handle head 3. A limiting groove 71 is provided on the limiting plate 7, and the connecting post 22 is slidably disposed in the limiting groove 71. A limiting pin 9 is provided on the handle head 3.

[0035] It should be noted that the working principle of this reinforced anti-theft lever lock is as follows: The lock cylinder 1 is installed on the door, and there are panels 2 on both sides of the door. The panels 2 are connected by mounting bolts 5 through the door. The protective plate assembly 4 is also installed on the door. The protective plate assembly 4 includes protective plates 41 on both sides of the door. One side of the protective plate 41 is provided with a female sleeve 43. The male sleeve 42 passes through the other side of the protective plate 41 and is threadedly connected to the female sleeve 43 to fix the protective plate 41 to the door. The protective plate 41 has a through hole through which the mounting bolt 5 passes. The protective plate 41 is provided with a sliding groove 61 on both sides of the through hole. The locking plate 6 is slidably installed in the groove. The sliding groove 61 is provided with a reset plate 62. There is a spring 63 between the plate 62 and the locking plate 6. During installation, the mounting bolt 5 passes through the guard plate 41 and can press the locking plate 6 against the inclined surface on the locking plate 6, causing the locking plate 6 to slide in the slide groove 61. At the same time, the spring 63 is compressed, thereby causing the locking plate 6 to move. By embedding the locking plate 6 into the inner side of the limiting platform 21 on the panel 2, the guard plate 41 and the panel 2 are connected. When the mounting bolt 5 is threaded and tightened with the mounting nut 51 on the inner surface of one of the panels 2, the connection between the two panels 2 is completed. In this way, the locking plate 6 forms a multi-point connection between the panel 2 and the door, strengthening the connection between the door and the panel 2.

[0036] The handle head 3 is rotatably mounted on the panel 2 and connected to the connecting post 22 on the panel 2 via a torsion spring 8. A slot is formed on the handle head 3, and the locking block 72 on the fitted limiting plate 7 is embedded in the slot. When the handle head 3 rotates, the connecting post 22 moves in the limiting groove 71, thereby limiting the rotation angle of the handle head 3. The connection strength of the handle head 3 is reinforced by the connecting post 22 and the limiting groove 71, preventing the limiting plate 7 from breaking or deforming when criminals violently rotate the handle head 3. Once the handle head 3 is rotated excessively, it is very likely to damage the door lock by excessively rotating the square steel, thus comprehensively improving the anti-theft performance of the handle lock.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
