[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] like Figures 1 to 7 As shown, it includes a first lock body 3 and a second lock body 4. The surface of the first lock body 3 is provided with an installation groove 8. The inner side of the installation groove 8 is provided with a limiting groove 10, and the limiting groove 10 is axially symmetrical about the installation groove 8. The installation groove 8 is provided with a reset component 1 for fixing the elevator car door. The two sides of the second lock body 4 are fixed with connecting rods 6. One end of the connecting rod 6 is fixed with an anti-jamming component 2 for cleaning foreign objects on the surface of the cable.

[0030] Specifically, the reset component 1 has a simple structure, which allows the elevator car door to lock automatically after closing, preventing users from prying open the car door and causing danger. The anti-jamming component 2 can clean foreign objects adhering to the surface of the cable, preventing the device from being jammed by foreign objects adsorbed on the surface of the cable. These simple designs not only reduce the production cost of the device, but also improve its practicality.

[0031] The reset assembly 1 includes a locking block 105, which is rotatably connected to the mounting groove 8 and movably connected to the limiting groove 10. A connecting block 102 is fixed on the bottom surface of the locking block 105. A first reset spring 101 is fixed between the connecting block 102 and the limiting groove 10, and both ends of the first reset spring 101 are fixedly connected to the connecting block 102 and the limiting groove 10, respectively. A movable piece 104 is provided on the side of the connecting block 102, and the movable piece 104 is rotatably connected to the connecting block 102. A second reset spring 103 is fixed between the movable piece 104 and the connecting block 102, and both ends of the second reset spring 103 are fixedly connected to the connecting block 102 and the movable piece 104, respectively.

[0032] Specifically, in the reset assembly 1, under the action of the first reset spring 101, the connecting block 102 rotates the locking block 105 out of the mounting groove 8, and then the locking block 105 engages with the bottom surface of the elevator car door to prevent the car door from being forcibly opened after closing. The thickness of the connecting block 102 is greater than the thickness of the locking block 105, which facilitates the application of pressure to the connecting block 102 later. Moreover, the elastic force of the second reset spring 103 is greater than that of the first reset spring 101. When the locking block 105 rotates to the limit groove 10, if the guide block 9 continues to move, the movable piece 104 will press the second reset spring 103 and rotate towards the connecting block 102.

[0033] The anti-jamming component 2 includes a mounting frame 202, which is fixedly connected to the connecting rod 6. Guide wheels 201 are arranged in an array inside the mounting frame 202 and are rotatably connected to the mounting frame 202. The guide wheels 201 are alternately arranged in the mounting frame 202. Cleaning sleeves 203 are provided inside the mounting frame 202 and are rotatably connected to the mounting frame 202.

[0034] Specifically, in the anti-jamming component 2, the guide wheels 201 arranged alternately inside the mounting frame 202 will move along the elevator cable. During the movement, the cleaning sleeve 203 will scrape and remove foreign objects from the surface of the cable from the top and bottom of the mounting frame 202.

[0035] The surface of the second lock body 4 is fixed with a guide block 9. The surface of the guide block 9 is provided with a groove 12, and the groove 12 is axially symmetrical about the guide block 9. The top surface of the second lock body 4 is provided with mounting holes 5. The surface of the first lock body 3 is fixed with a positioning piece 11, and the surface of the second lock body 4 is inlaid with a positioning sensor 7.

[0036] Specifically, the positioning sensor 7 and the positioning piece 11 enable the first lock body 3 and the second lock body 4 to be accurately positioned. After the positioning sensor 7 and the positioning piece 11 are accurately positioned, the guide block 9 will push the locking block 105 completely into the limiting groove 10. The inclined groove 12 on the surface of the guide block 9 will guide the block 9 to move downwards later.

[0037] In summary: In reset assembly 1, under the action of the first reset spring 101, the connecting block 102 rotates the locking block 105 out of the mounting groove 8. Then, the locking block 105 engages with the bottom surface of the elevator car door to prevent the car door from being forcibly opened after closing. The thickness of the connecting block 102 is greater than the thickness of the locking block 105, which facilitates applying pressure to the connecting block 102 later. Moreover, the elastic force of the second reset spring 103 is greater than that of the first reset spring 101. When the locking block 105 rotates to the limit groove 10, if the guide block 9 continues to move, the movable piece 104 will press the second reset spring 103 and rotate towards the connecting block 102. In anti-jamming assembly 2, the guide wheels 201 arranged alternately inside the mounting frame 202 will move along the elevator cable. During the movement, the cleaning sleeve... The cylinder 203 scrapes and removes foreign objects from the surface of the cable from above and below the mounting frame 202. The positioning sensor 7 and the positioning piece 11 enable the first lock body 3 and the second lock body 4 to be accurately positioned. After the positioning sensor 7 and the positioning piece 11 are accurately positioned, the guide block 9 will push the locking block 105 completely into the limiting groove 10. The inclined groove 12 on the surface of the guide block 9 guides the block 9 to move downwards later. The reset component 1 has a simple structure, which enables the elevator car door to be automatically locked after closing, avoiding the danger caused by the user prying open the car door. The anti-jamming component 2 can clean the foreign objects adhering to the surface of the cable, preventing the device from being jammed by foreign objects adsorbed on the surface of the cable. These simple designs not only reduce the production cost of the device, but also improve the practicality of the device.
