Furthermore, manual measurement requires inspectors to possess high levels of professional skills and experience, increasing the operational difficulty and cost.

[0028] To solve this technical problem, this utility model provides a portable elevator car leveling accuracy measuring tool, which is used for measuring the leveling accuracy of elevator cars.

[0029] For details, please refer to Figures 1-2 Portable elevator car leveling accuracy measuring tools specifically include:

[0030] Support block 1, a ruler 2 is vertically inserted and connected to one end of support block 1, a limit knob 3 for limiting the movement of ruler 2 is provided on the front of support block 1, and a level bubble 5 is provided at the upper end of support block 1 and away from ruler 2.

[0031] A connecting rope 4 is provided between the ruler 2 and the limit knob 3, and the two ends of the connecting rope 4 are fixedly connected to the ruler 2 and the limit knob 3 respectively.

[0032] The right end of the support block 1 has a vertically opening guide slot 6. The ruler 2 is vertically connected to the support block 1 through the guide slot 6. The right end of the front of the support block 1 has a longitudinally opening limit hole 7. The limit hole 7 is connected to the inside of the guide slot 6. The limit knob 3 is threadedly connected to the limit hole 7. One end of the limit knob 3 located inside the limit hole 7 can extend into the inside of the guide slot 6.

[0033] The portable elevator car leveling accuracy measuring tool provided by this utility model, through the structural design of support block 1, ruler 2, limit knob 3, and spirit level 5, allows the device to support the ruler 2 through support block 1, measure the leveling accuracy of the elevator car by sliding the ruler 2, limit the ruler 2 by limit knob 3 to prevent accidental sliding of the ruler 2 from affecting the measurement results, and ensure that the device is in a horizontal state by spirit level 5.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Please refer to Figures 1-2 A portable elevator car leveling accuracy measuring tool, comprising:

[0037] Support block 1 has a ruler 2 vertically connected to one end. The front of support block 1 has a limiting knob 3 for limiting the movement of the ruler 2. A level bubble 5 is located at the top of support block 1, away from the ruler 2. The level bubble 5 is used to determine whether the bottom surface of support block 1 is level. The ruler 2 can slide freely up and down. When the level bubble 5 is level, the length of the ruler 2 extending beyond the bottom surface of support block 1 is the leveling accuracy. The ruler 2 can be shortened to the same height as support block 1. When not in use, it can be fixed by tightening the limiting knob 3, which further enhances portability.

[0038] Specifically, a connecting rope 4 is provided between the ruler 2 and the limit knob 3. The two ends of the connecting rope 4 are fixedly connected to the ruler 2 and the limit knob 3 respectively. The connecting rope 4 is used to fasten the ruler 2 and the limit knob 3 to prevent the ruler 2 from slipping and falling into the gap between the sills during measurement.

[0039] Specifically, a guide slot 6 is vertically provided on the right end of the support block 1. The ruler 2 is vertically connected to the support block 1 through the guide slot 6. A limit hole 7 is vertically provided on the right end of the front of the support block 1. The limit hole 7 is connected to the inside of the guide slot 6. The limit knob 3 is threadedly connected to the limit hole 7. One end of the limit knob 3 located inside the limit hole 7 can extend into the inside of the guide slot 6.

[0040] When in use, the bottom surface of the level bubble 5 on the left end of the support block 1 contacts the surface of the higher sill of the car sill or landing sill. When the level bubble 5 is horizontal, the right ruler 2 extends out and contacts the surface of the lower sill. Tighten the limit knob 3 to fix the position of the ruler 2. At this time, you can pick up the device to read the value.

[0041] Example 2:

[0042] The portable elevator car leveling accuracy measurement tool provided in Example 1 has been further optimized, specifically, as follows: Figure 2 As shown, the middle part of the connecting rope 4 is arranged in a straight spiral. One end of the connecting rope 4 is rotatably connected to the limit knob 3, and the other end of the connecting rope 4 is detachably connected to the ruler 2 through a connecting ring.

[0043] Through the above structural design, when the ruler 2 is taken out of the limiting hole 7 for independent use, the connecting rope 4, which is set in a straight spiral, can be stretched. Through the connection method of the connecting ring, the connecting rope 4 can be separated from the ruler 2, thus facilitating the replacement of the ruler 2.

[0044] Example 3:

[0045] The portable elevator car leveling accuracy measurement tool provided in Example 1 has been further optimized, specifically, as follows: Figure 3As shown, the support block 1 includes a block body 8 and a block sub-body 9. The block body 8 has a placement cavity 12 inside. The opening of the placement cavity 12 faces the side of the block body 8 closer to the block sub-body 9. The block body 8 and the block sub-body 9 are detachably connected by a connecting structure.

[0046] Furthermore, in order to improve the stability of the center of gravity after the device is placed, the placement cavity 12 is located in the middle and upper part of the block body 8, and the lower part of the block body 8 is a solid structure.

[0047] Through the above structural design, the storage cavity 12 facilitates the storage of other small tools / accessories, and the connecting structure allows for the detachable connection between the main block 8 and the sub-block 9, giving the device a storage function.

[0048] Example 4:

[0049] The portable elevator car leveling accuracy measurement tool provided in Example 3 has been further optimized, specifically, as follows: Figures 3-4 As shown, the connection structure includes a connecting insert plate 10 and a connecting slot 11. The right end of the block 9 near the block body 8 has a protrusion, and the right end of the block body 8 near the block 9 has a recess. The connecting insert plate 10 is fixed to the side of the block 9 and located at the protrusion. The connecting slot 11 is fixed to the side of the block body 8 and located at the recess. The block body 8 and the block 9 are connected laterally by the structural cooperation of the connecting insert plate 10 and the connecting slot 11.

[0050] Furthermore, the connection structure also includes an adsorption block 13 and an adsorption component 2 14. The adsorption block 13 is embedded and fixed on the side of the block body 8 and away from the recessed end. The adsorption component 2 14 is embedded and fixed on the side of the block body 9 and away from the protruding end. The adsorption block 13 and the adsorption component 2 14 are magnetically connected.

[0051] Furthermore, the guide slot 6 is located at the protrusion of the block 9, and the limiting hole 7 corresponds to the position of the guide slot 6.

[0052] Through the above structural design, the sliding connection of the block body 8 and the block sub-body 9 can be realized by the cooperation of the connecting insert plate 10 and the connecting slot 11, and the connection limit of the block body 8 and the block sub-body 9 can be realized by the cooperation of the adsorption block one 13 and the adsorption component two 14.
