Specific embodiments

[0038] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0039] Reference Figures 1-4 , the utility model provides an embodiment: a kind of measuring device of elevator door lock engagement depth, including support rod 1, support rod 1 as the basic structure of entire measuring device, provide stable support effect, support rod 1 side fixedly connected with dog one 2, for with the engagement part of the connection of elevator door lock, support rod 1 outer wall is slidably connected with slide frame 3, and slide frame 3 side is fixedly connected with dog two 4, and the function of dog two 4 is to cooperate with another part of elevator door lock, ensure the engagement accuracy in measurement process, support rod 1 inside is provided with multiple limit holes 5, and slide frame 3 outer wall is slidably connected with display module 9, including screen and operation interface for real-time display measurement result, sensor 10 is arranged in display module 9, for capturing the engagement depth information of elevator door lock, and it is transmitted to display module 9 and is handled, and slide frame 3 inside is provided with adjusting assembly, and display module 9 inside is provided with assembly assembly;

[0040] The adjusting assembly includes a positioning pin 6 that is slidingly connected inside the sliding frame 3 and the limiting hole 5. One end of the positioning pin 6 is shaped as an inclined surface, which helps to stably guide the positioning pin 6 during movement. The other end of the positioning pin 6 is fixedly connected with a fixed block 7. A spring 1 8 is sleeved on the outer wall of the positioning pin 6, and the two ends of the spring 1 8 are fixedly connected inside the fixed block 7 and the sliding frame 3, respectively. The spring 1 8 provides additional elastic force to ensure that the positioning pin 6 can smoothly enter or exit the limiting hole 5 when needed, achieving precise limiting control. A connection block 1 1 is fixedly connected to one side of the display module 9. A pulley 1 2 is rotatably connected to the outer wall of the connection block 1 1. A sliding groove 1 3 is formed in the inner part of the supporting rod 1. The pulley 1 2 is slidingly connected to one side of the supporting rod 1, which can effectively reduce the friction of the push-pull rod 1 4 during sliding, ensuring smooth and stable sliding.

[0041] Specifically, when using the measuring device, first, the claw 1 and the claw 2 need to be accurately inserted into the engagement part of the elevator door lock to start the measurement process. Next, by pulling the push-pull rod 1 4 connected with the sliding frame 3, the sliding frame 3 is driven to slide along the outer wall of the supporting rod 1. The sliding of the sliding frame 3 makes the claw 2 further cooperate with the engagement part of the elevator door lock, and the positioning pin 6 inside the sliding frame 3 also moves. During the movement of the positioning pin 6, it is limited by the inner wall of the supporting rod 1 to prevent excessive sliding or deviation, thereby ensuring the accurate position of the sliding frame 3 and the claw 2. The movement of the positioning pin 6 in the sliding frame 3 drives the fixed block 7 connected with the spring 1 8. When the fixed block 7 is stressed, the spring 1 8 will be stretched, which ensures the precision and stability of the system. It is worth noting that when the claw 2 moves to the predetermined position, the spring 1 8 will unload the load, and through the rebound effect, it will push the positioning pin 6 to slide into another corresponding limiting hole 5, thereby completing the fixation and further controlling the position of the claw 2. By adjusting the relative position of the sliding frame 3 and the claw 2, the display module 9 and the sensor 1 0 can be accurately adjusted, so that they can measure the engagement depth of the elevator door lock, ensuring the accuracy and reliability of the measurement data. During the measurement process, the display module 9 is responsible for displaying the real-time measurement results, while the sensor 1 0 is used to capture the engagement depth information of the elevator door lock and transmit it to the display module 9 for processing.

[0042] Reference Figure 2 , Figure 5 and Figure 6The assembling assembly comprises the hollow column 16 and the catch pin 17. The hollow column 16 is arranged at one side of the display module 9. The catch pin 17 is slidably connected in the hollow column 16. The catch pin 17 is slidably connected in the display module 9. The sliding frame 3 is provided with the positioning hole 15. The catch pin 17 is slidably connected in the positioning hole 15. The catch pin 17 is fixedly connected with the sliding column 18 at one end. The sliding column 18 is rotatably connected with the wrench 19 on the outer wall. The wrench 19 facilitates the manual adjustment of the operator. The sliding column 18 is sleeved with the spring 20 on the outer wall. The spring 20 is fixedly connected in the hollow column 16 and the catch pin 17 at two ends respectively. The spring 20 ensures that the catch pin 17 can quickly rebound during the adjustment process, maintains the flexibility of the device, and is fixedly connected with the fixed column 21 in the catch pin 17. The fixed column 21 is fixedly connected with the support column 22 on the outer wall. The support column 22 is slidably connected with the clamping ball 23 on the outer wall. The clamping ball 23 is slidably connected in the catch pin 17. The support column 22 is sleeved with the spring 24 on the outer wall. The spring 24 is fixedly connected in the fixed column 21 and the clamping ball 23 at two ends respectively.

[0043] Specifically, when the display module 9 and the sensor 10 need to be disassembled, the wrench 19 is first rotated. The rotation of the wrench 19 drives the sliding column 18 to slide in the hollow column 16. The sliding column 18 is connected with the catch pin 17. When the sliding column 18 continues to slide, the catch pin 17 slides into the hollow column 16. At this time, the catch pin 17 exerts pressure on the spring 20, causing the spring 20 to contract. With the contraction of the spring 20, the clamping ball 23 in the catch pin 17 is pressed by the inner wall of the hollow column 16. The clamping ball 23 immediately slides into the catch pin 17, thereby compressing the spring 24. Through the rebounding action of the spring 24, it is ensured that the catch pin 17 can smoothly separate from the positioning hole 15 in the sliding frame 3 during the disassembly process. When the catch pin 17 is separated, the display module 9 and the sensor 10 can be removed from the outer wall of the sliding frame 3, completing the disassembly. During the installation process, the display module 9 is only needed to be correctly buckled on the outer wall of the sliding frame 3, and the hollow column 16 is needed to be closely fitted at the installation position of the sliding frame 3 and the display module 9. Next, by rotating the wrench 19, the catch pin 17 reenters the positioning hole 15, completing the fixation. This process is accompanied by the rebounding action of the spring 20 and the spring 24, so that the catch pin 17 can be firmly inserted into the positioning hole 15. The clamping ball 23 is reset and firmly clamped into the positioning hole 15, thereby completing the installation of the display module 9 and the sensor 10.

[0044] Working principle: when using the measuring device, first insert the clamping jaw 2 and the clamping jaw 4 into the meshing part of the elevator door lock, then pull the push-pull rod 14 to drive the sliding frame 3 to slide on the outer wall of the supporting rod 1, the sliding frame 3 drives the clamping jaw 4 on one side to move, and the sliding frame 3 also drives the positioning pin 6 inside to move, the positioning pin 6 is limited by the inner wall of the supporting rod 1 during movement, so that the positioning pin 6 slides inside the sliding frame 3, and the positioning pin 6 drives the fixed block 7 at one end to move, the fixed block 7 drives the spring 8 at one end to stretch under force, and when the clamping jaw 4 moves to a certain position, the spring 8 will unload and rebound, thereby driving the positioning pin 6 to slide into the corresponding limiting hole 5 inside to be fixed, so that the position of the clamping jaw 4 is more easily controlled, by adjusting the position of the sliding frame 3 and the clamping jaw 4, the sliding frame 3 drives the display module 9 and the sensor 10 on the outer wall to move, so as to measure the meshing depth of the door lock, when it is necessary to disassemble the display module 9 and the sensor 10 from the outer wall of the sliding frame 3, first rotate the wrench 19 to drive the sliding column 18 to slide inside the hollow column 16, the sliding column 18 drives the cotter pin 17 to slide into the hollow column 16, the cotter pin 17 is pressed against the spring 20 under force, so that the spring 20 is contracted, in this process, the clamping ball 23 inside the cotter pin 17 is pressed against the inner wall of the hollow column 16, so that the clamping ball 23 slides into the cotter pin 17, and the spring 24 is compressed, thereby making the cotter pin 17 separate from the positioning hole 15 inside the sliding frame 3, then the display module 9 and the sensor 10 are taken off from the outer wall of the sliding frame 3 to complete disassembly, when installing, only need to buckle the display module 9 on the outer wall of the sliding frame 3, then fit the hollow column 16 on the installation part of the sliding frame 3 and the display module 9, then rotate the wrench 19 back to the original position, at this time, the spring 20 unloads and rebounds, thereby driving the cotter pin 17 to reset, so that it is inserted into the positioning hole 15, and the spring 24 unloads and rebounds to drive the clamping ball 23 to reset, so that it is clamped in the positioning hole 15 to complete fixation, thereby achieving the effect that the display module 9 is convenient to assemble and replace.

[0045] Finally, it should be pointed out that: the above only describes preferred embodiments of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
