DETAILED DESCRIPTION

[0030] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0031] The present application provides an ultra-thin elevator lock, which is used to solve the problems of traditional elevator locks having a complex structure, a large size, and a single function.

[0032] like Figures 1 to 6 As shown, in one embodiment of the present application;

[0033] Overall Figure 1 As shown: an ultra-thin elevator lock, including a shell 1, a lock shell 2, a lock core 3 and a lock body 6. The overall length, the lock core 3 and the lock body 6 adopt a common mechanical lock core. The length of the entire ultra-thin elevator lock is slightly greater than the length of the entire lock core 3. Its internal mechanical control devices are all in the shell 1, which simplifies the middle control structure and greatly reduces the overall size.

[0034] Specifically, Figure 2 As shown in the overall exploded schematic diagram: the housing 1 includes a lower housing 11 and an upper housing 12, wherein the lower housing 11 and the upper housing 12 are detachably connected and fixed mainly by a plurality of circumferential screws.

[0035] A lock cavity 10 is formed between the lower shell 11 and the upper shell 12. A rotation control device 4 is arranged in the lock cavity 10. The rotation control device 4 includes a rotation protrusion 41 and a trigger member 42. The rotation of the rotation protrusion 41 drives the trigger member 42 to change its position state. The trigger member 42 is connected to the cable assembly 7. The cable assembly 7 is connected to an external control system. The control system is connected to different devices, such as a fan or a lighting system, or runs different operating modes, such as ATTVIP, TUG, and BL. The circuit of the cable assembly 7 is turned on and off by rotating the rotation protrusion 41, and a switch signal is sent. The entire ultra-thin elevator lock can be arranged in multiple arrangements to control multiple devices.

[0036] A connecting block 31 is provided at the end of the lock core 3, and a rotating hole 410 that matches the shape of the connecting block 31 is provided at the center of the rotating protrusion 41. The connecting block 31 drives the rotating protrusion 41 to rotate. The cross-section of the connecting block 31 is square. The connecting block 31 is clamped in the rotating hole 410. The connecting block 31 and the rotating hole 410 are key-connected, and the whole is firm and stable, maintaining synchronous rotation.

[0037] A receiving groove 121 and a connecting hole 120 are provided on the upper shell body 12, and the lock shell 2 is snap-fitted and fixed in the receiving groove 121. The lock shell 2 and the receiving groove 121 on the upper shell body 12 remain stationary, and the lock core 3 passes through the lock shell 2 and the connecting hole 120 in sequence. The bottom end of the lock core 3 and the rotating protrusion 41 are coaxially rotated together, and the lock core 3 can only complete the rotation after it is correctly matched with the lock body 6, thereby driving the rotating protrusion 41 to rotate.

[0038] like Figure 3-5 As shown, the utility model relates to a rotation control device 4, which includes a rotation protrusion 41 and a trigger member 42. The rotation protrusion 41 is provided with an opening groove 411 and a closing groove 412 on its circumference. The trigger member 42 includes a trigger rod 421, a connecting body 422 and a connecting rod 423. One end of the connecting body 422 is connected to the trigger rod 421, and a spring 424 is provided at one end of the connecting body 422 away from the trigger rod 421.

[0039] The depth of the opening groove 411 is greater than the depth of the closing groove 412. The opening groove 411 and the closing groove 412 are arranged at 90 degrees in sequence. By adjusting the opening groove 411 or the closing groove 412 to be clamped on the trigger rod 421, the connection between the connecting rod 423 and the two cable connectors 73 can be achieved, and the cable output end 71 outputs a switching signal, thereby realizing the switching device or mode of the external control system.

[0040] like Figure 2 and Figure 5 As shown, the cable assembly 7 includes a cable output end 71, two cable lines 72 and two cable connectors 73. The cable output end 71 is connected to an external control system, one end of the two cable lines 72 are connected to the cable output end 71, and the other ends of the two cable lines 72 are respectively connected to the cable connectors 73. The two cable connectors 73 are in a disconnected state and can be connected through a connecting rod 423 made of a metal conductive material. The two ends of the connecting rod 423 are used to connect the two cable connectors 73.

[0041] like Figure 5 As shown, in another embodiment of the utility model patent, two trigger members 42 are provided, which are 180 degrees apart and symmetrically arranged on both sides of the rotating protrusion 41. The rotating protrusion 41 is provided with an opening groove 411 and a plurality of closing grooves 412 on the circumference. One trigger member 42 controls one device or mode. The utility model can be provided with one or two trigger members 42 according to needs.

[0042] The upper shell 12 is provided with a rotation limit seat 122 and a trigger limit seat 123, the rotation protrusion 41 is located in the rotation limit seat 122, the trigger member 42 is located in the trigger limit seat 123, the rotation limit seat 122 includes two arc plates 1221, the two arc plates 1221 surround a rotation limit groove 1220 with the same diameter as the rotation protrusion 41, and the rotation protrusion 41 is rotatably engaged in the rotation limit groove 1220. By providing two arc plates 1221 to surround a rotation limit groove 1220 with the same diameter as the rotation protrusion 41, the rotation position of the rotation protrusion 41 can be limited.

[0043] like Figure 6 As shown, a nameplate 5 is provided on the surface of the lock housing 2, and a plurality of status indication marks 51 are provided on the surface of the nameplate 5. The marks may be fan or lighting system marks, or different operating modes, such as ATT VIP, TUG, and BL. The operator may quickly identify the main functions and on / off states of the elevator lock according to the marks.

[0044] Working principle: When the elevator operator inserts the lock body 6 and rotates the lock core 3, the rotating protrusion 41 is driven to rotate, and the opening groove 411 is turned to one of the trigger rods 421. At this time, under the compression of the spring 424, the trigger rod 421, the connecting body 422 and the connecting rod 423 are pushed to move, and the corresponding trigger rod 421 is against the opening groove 411, and the two ends of the connecting rod 423 are respectively against the two ends of the corresponding cable connector 73, so that the cable output end 71 is connected, and an electrical signal is sent to the external control system to control the corresponding device or mode to start.

[0045] When the elevator operator completes maintenance or the mode needs to be closed, the lock body 6 is inserted again, and the lock core 3 is rotated to drive the rotating protrusion 41 to rotate, so that the opening groove 411 turns to neutral, and the closing groove 412 and the trigger rod 421 begin to cooperate. At this time, the spring 424 is squeezed by the trigger rod 421 and the connecting body 422 and is in a compressed state, and the two ends of the connecting rod 423 are away from the two cable connectors 73, so that the cable output end 71 is disconnected, and the corresponding equipment is stopped or the mode is closed.

[0046] By directly connecting the lock core and the rotary control device, they rotate synchronously while unlocking, reducing the number of intermediate connecting parts, which is beneficial to reducing the size, and realizing the replacement of various functions by rotating the rotary control device; the control of various working states of the elevator is realized by the lock core and multiple cables. The elevator lock provided by the present invention is accurate in positioning, shortened in length and greatly improved in sensitivity, realizes multiple functions through one lock, reduces production costs, has a reasonable design and a simple structure, and is easy to install.

[0047] The technical features of the above embodiments may be combined arbitrarily, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
