[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0032] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for 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. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figure 1-7As shown, the elevator guide rail calibrator proposed in this utility model includes a base block 7. Both ends of the base block 7 are connected to the abutment plate 6 by hinges. The side of the abutment plate 6 away from the base block 7 is connected to the sliding shell 5 by the connecting block 12. A sliding rod 19 is slidably connected inside the sliding shell 5. A concave block 8 is installed at the end of the sliding rod 19 away from the base block 7. A laser vertical instrument body 2 is installed at the bottom of the concave block 8.

[0035] A limiting component 4 is provided at one end of the upper side of the sliding housing 5, and a plurality of equally spaced triangular grooves 3 are provided on the upper side of the sliding rod 19. The limiting end of the limiting component 4 is connected to the insert block 9, and the insert block 9 abuts against the triangular groove 3 that is adapted to it.

[0036] It also includes fixing plates 11, which are symmetrically distributed on both sides of the base block 7;

[0037] A connecting component 13 is installed on the outer side of the fixing plate 11. The connecting end of the connecting component 13 passes through the fixing plate 11 connected thereto and is connected to the connecting block 12.

[0038] The concave block 8 has a clamping component installed inside.

[0039] In this utility model, during use, the position of the sliding rod 19 and the inside of the sliding housing 5 is adjusted by the gap between the elevator guide rails, so as to adapt to elevator guide rails with different gaps. The magnet plates 1 on both sides are installed on the elevator guide rails. Then, the magnet plates 1 are fixed on the elevator guide rails by the clamping assembly. Then, the laser vertical instrument bodies 2 on both sides are started to measure the elevator guide rails. After the measurement is completed, the above steps are reversed to remove the magnet plates 1.

[0040] When folding is required, first cancel the limiting effect of the two side limiting components 4, then move the sliding rod 19 into the sliding shell 5 and activate the limiting function of the two side limiting components 4.

[0041] Then, by removing the connecting components 13 on both sides to limit the movement, the sliding shells 5 on both sides can be folded, further shortening the overall length and making it easier to carry and store. When needed, simply reverse the above steps.

[0042] In an optional embodiment, the clamping assembly includes a rotating handle 15. Second threaded rod 16The concave block 8 is connected to a connecting plate 20 and a guide rod 14. The middle thread of the second threaded rod 16 passes through the side of the concave block 8. One end of the second threaded rod 16 is coaxially connected to the rotating handle 15, and the other end of the second threaded rod 16 is connected to the connecting plate 20. Multiple guide rods 14 slide through the side of the concave block 8 and are connected to the connecting plate 20. The second threaded rod 16 is perpendicular to the concave block 8, and the guide rod 14 is parallel to the second threaded rod 16. Anti-slip plates 10 are symmetrically distributed on one inner wall of the concave block 8 and on the connecting plate 20.

[0043] It should be noted that when it needs to be fixed on the elevator guide rail, the concave block 8 is first installed on the elevator guide rail, and then the rotating handle 15 is rotated. Rotating the handle 15 can drive the second threaded rod 16 to rotate. When the second threaded rod 16 rotates, it can drive the connecting plate 20 to move, so that it can fix and limit the elevator guide rail. When the connecting plate 20 moves, it can drive the multiple guide rods 14 connected to it to move on the concave block 8, ensuring the stability of the movement of the connecting plate 20. Furthermore, the anti-slip plate 10 improves the stability of the concave block 8 fixed on the elevator guide rail.

[0044] In an optional embodiment, magnet plates 1 are symmetrically mounted on the sides of both concave blocks 8.

[0045] It should be noted that during folding, the magnetic plates 1 on the concave blocks 8 on both sides are connected by magnetic force, ensuring the stability of the folding.

[0046] In an optional embodiment, the connecting assembly 13 includes a butterfly throttle 1301, a limiting frame 1302, a first threaded rod 1303, and a second limiting plate 1304. The limiting frame 1302 is disposed on the side of the fixing plate 11. One end of the first threaded rod 1303 passes through the fixing plate 11 connected thereto and extends into the connecting block 12. The other end of the first threaded rod 1303 passes through the limiting frame 1302 connected thereto and is coaxially connected to the butterfly throttle 1301. The first threaded rod 1303 and the connecting block 12 are threadedly connected. The second limiting plate 1304 is installed on the outer end face of the first threaded rod 1303 and is located between the limiting frame 1302 and the fixing plate 11.

[0047] It should be noted that when the sliding housing 5 is extended, the connecting block 12 connected to the sliding housing 5 will come into contact with the fixing plate 11. Then, by rotating the butterfly handle 1301, the butterfly handle 1301 can drive the first threaded rod 1303 to rotate, so that the first threaded rod 1303 is threadedly connected to the connecting block 12, thereby fixing the connecting block 12 to the fixing plate 11 and ensuring the stability of use.

[0048] Furthermore, the second limiting plate 1304 can limit the first threaded rod 1303 inside the limiting frame 1302, preventing the first threaded rod 1303 from being lost when it is not fixed.

[0049] In an optional embodiment, the limiting component 4 includes a lifting handle 401, a limiting housing 402, a first limiting plate 403, a limiting rod 404, and a spring 405. The limiting housing 402 is located on the upper side of the sliding housing 5 away from the base block 7. One end of the limiting rod 404 passes through the upper end face of the limiting housing 402 and is connected to the lifting handle 401. The other end of the limiting rod 404 passes through the upper end of the sliding housing 5 and is connected to the insert block 9. The spring 405 is sleeved on the outer end face of the limiting rod 404. The first limiting plate 403 is installed on the outer end face of the limiting rod 404. The spring 405 and the first limiting plate 403 are located inside the limiting housing 402. The spring 405 is located between the first limiting plate 403 and the inner top wall of the limiting housing 402. The triangular groove 3 is adapted to the shape of the insert block 9.

[0050] It should be noted that when the sliding rod 19 extends outward, it can be pulled outward to adjust its position inside the sliding housing 5. When the sliding rod 19 is pulled outward, the insert 9 can be inserted into different triangular grooves 3 in sequence. When the insert 9 is inserted from one triangular groove 3 into the next, the insert 9 will push upward, thereby driving the limiting rod 404 to move upward. When the limiting rod 404 moves, the spring 405 can be contracted by the first limiting plate 403. When the insert 9 enters the next triangular groove 3, the spring 405 will extend from its contracted state, thereby driving the insert 9 to be inserted into the next triangular groove 3 through the first limiting plate 403 and the limiting rod 404.

[0051] Furthermore, through the triangular groove 3 and the insert 9, the sliding rod 19 can be pulled outward without pulling the lifting handle 401 upward. When the sliding rod 19 moves into the sliding housing 5, the lifting handle 401 needs to be pulled upward so that it can drive the first limiting plate 403 upward through the limiting rod 404. The insert 9 will be pulled out from inside the triangular groove 3, and the spring 405 will be in a contracted state at this time. When the sliding rod 19 is moved into the sliding housing 5 to the designated position, the lifting handle 401 can be released. At this time, the spring 405 will extend, so that it can drive the limiting rod 404 downward through the first limiting plate 403, so that the insert 9 can be inserted into the designated triangular groove 3, thereby achieving the purpose of moving the sliding rod 19 into the sliding housing 5.

[0052] In an optional embodiment, sliding grooves 17 are provided on the inner walls of the upper and lower sides of the sliding housing 5, and limiting sliders 18 adapted to the sliding grooves 17 are installed on the upper and lower ends of the sliding rod 19. The limiting sliders 18 on both sides are slidably connected to the sliding grooves 17 on both sides respectively.

[0053] It should be noted that when the sliding rod 19 slides inside the sliding housing 5, the limiting sliders 18 on both sides of the sliding rod 19 will slide in the sliding groove 17 connected to them, ensuring the stability of the sliding rod 19 inside the sliding housing 5. Furthermore, the sliding groove 17 can limit the sliding rod 19 inside the sliding housing 5, preventing the sliding rod 19 from separating from the sliding housing 5.

[0054] In an optional embodiment, the abutment plate 6 has an L-shaped structure.

[0055] It should be noted that when the sliding outer shells 5 on both sides are folded, the abutment plates 6 on both sides will come into contact with each other, ensuring that the hinge rotation angle of the sliding outer shell 5 is 90° when it is folded.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
