[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0017] Reference Figure 1-4This utility model embodiment proposes a device for measuring the gap between the landing doors of a double-leaf horizontal sliding elevator. It includes a base 1, a mounting platform 2 and a battery compartment 3 mounted on one outer wall of the base 1. The mounting platform 2 is located to one side of the battery compartment 3, and an electric push rod 4 is mounted on one outer wall of the mounting platform 2. The electric push rod 4 is a miniature electric push rod with a thrust of 150N, a self-locking force of 150N, and a stroke of 10-200mm. A sliding block 7 is fixedly connected to the output end of the electric push rod 4. A measuring scale 5 is mounted on one outer wall of the base 1 near the horizontal side of the mounting platform 2. The measuring scale 5 uses a 0-1... A portion of a 50mm digital vernier caliper retains the caliper body structure and digital measurement structure. The measuring scale 5 has a sliding groove 6 inside, and the sliding block 7 is located inside the sliding groove 6 and slides against each other. The sliding connection ensures the stability of the linear movement of the sliding block 7 inside the measuring scale 5. A fixed measuring claw 9 is provided on one outer wall of the measuring scale 5, and a movable measuring claw 8 is provided on one outer wall of the sliding block 7 near the fixed measuring claw 9. A scale line 10 is provided on the outer wall of the measuring scale 5 adjacent to the fixed measuring claw 9, and the outer wall of the fixed measuring claw 9 is aligned with the 0 mark on the scale line 10. A guide cover 11 is provided on the outer wall of the sliding block 7 away from the output end of the electric push rod 4. The guide cover 11 is sleeved on the outside of the measuring ruler 5. A digital display LED screen 12 is provided on one outer wall of the guide cover 11. The electric push rod 4 and the digital display LED screen 12 are both electrically connected to the battery compartment 3. Since the elevator inspection regulations require that "for center-parting doors, the total value should not exceed 45mm", this inspection item is used as a measurement value judgment item. If it exceeds this value range, it can be judged as unqualified. Therefore, the measuring range of this device only needs to be greater than 45mm. To verify the clearance of elevator doors, in this embodiment, the elevator inspection regulations require that "a force of 150N be applied at the most unfavorable point in the fastest opening direction of horizontal sliding and folding landing doors." The device is placed at the desired measurement point, and the electric push rod 4 is controlled to drive the sliding block 7 and the moving measuring claw 8 linearly through its output end. Guided by the sliding groove 6, the moving measuring claw 8 is brought into contact with the fixed measuring claw 9. After initial setup, the tightly fitted moving measuring claw 8 and fixed measuring claw 9 are inserted into the clearance of the elevator door. As the moving measuring claw 8 and fixed measuring claw... Insert 9 until base 1 is attached to one side of the outer wall of the elevator door. Then, control the electric push rod 4 to pull the moving measuring claw 8 through its output end on one side, so that the preset thrust value of the electric push rod 4 is 150N. The moving measuring claw 8 and the fixed measuring claw 9 move in opposite directions. Under the push of the moving measuring claw 8, the elevator landing door is driven to create a gap. When the door pushing resistance and the thrust of the electric push rod 4 are balanced, the electric push rod 4 self-locks and holds at 150N. At this time, the value displayed on the digital display LED screen 12 is the door gap distance of the horizontal double-opening landing door under the action of 150N external force. Example

[0018] Reference Figure 1-4 In the above embodiment, the present invention includes a movable measuring claw 8 and a fixed measuring claw 9. Both the movable measuring claw 8 and the fixed measuring claw 9 are perpendicular to the base 1 and are horizontal to each other. This allows the base 1 to be in contact with one side wall of the elevator door, while the fixed measuring claw 9 contacts the other side wall of the elevator door, thus ensuring that the device fully fits the elevator door and can measure the gap of the elevator door. A first inclined groove 13 is provided on one outer wall of both the movable measuring claw 8 and the fixed measuring claw 9, and a second inclined groove 14 is provided on the other outer wall of both the movable measuring claw 8 and the fixed measuring claw 9. One end of the movable measuring claw 8 and the fixed measuring claw 9 is tapered under the action of inclined groove 13 and inclined groove 14. The tapered movable measuring claw 8 and the fixed measuring claw 9 can make one end of them pointed, which makes it easier to insert into the gap of the elevator door and facilitates the use of the device. A receiving cavity 15 is provided on one side of the outer wall of the fixed measuring claw 9 near the outer side of the movable measuring claw 8. The movable measuring claw 8 can be stored in the receiving cavity 15, and the movable measuring claw 8 and the fixed measuring claw 9 are in a mutually embedded state. This makes the two measuring claws mutually embedded at the 0 mark. The amount of movement of the movable measuring claw 8 is the gap distance of the elevator door. Before measurement, control the moving measuring claw 8 to move toward the fixed measuring claw 9, so that the moving measuring claw 8 is embedded in the receiving cavity 15. At this time, the moving measuring claw 8 and the fixed measuring claw 9 are embedded and overlapped with each other. One side wall of the moving measuring claw 8 and the fixed measuring claw 9 are both located at the 0 mark of the scale line 10. The two measuring claws are aligned and zeroed. The moving measuring claw 8 and the fixed measuring claw 9 are inserted into the measuring point of the elevator horizontal sliding landing door. The thrust generated after starting the electric push rod 4 drives the elevator landing door to create a gap. The preset thrust value of the electric push rod 4 is 150N. When the door pushing resistance and the thrust reach a balance, the electric push rod 4 self-locks and holds at 150N.
