[0029] An embodiment of the present utility model provides an elevator door gap measuring device, as Figure 1-8 shown, the elevator door gap measuring device includes: a support plate 1 and a connecting plate 2 fixedly installed on the support plate 1; a scale 3 provided at the top of the connecting plate 2 for measuring the elevator door gap; a group of pointers 4 slidably arranged on the connecting plate 2, and the group of pointers 4 are all in sliding contact with the scale 3; a rectangular cylinder 5 fixedly installed on one side of the connecting plate 2; a depth gauge 6 slidably arranged in the rectangular cylinder 5 for measuring the flatness of the elevator door plane; and a positioning mechanism provided on the support plate 1 for assisting in positioning the support plate 1.

[0030] In this embodiment, during use, first operate the positioning mechanism to make the L-shaped plate 16 of the positioning mechanism horizontally aligned with one side of the elevator door, so as to ensure that the support plate 1 will not be skewed when fixed on the elevator door. Then, through the suction cup 9, the support plate 1 is adsorbed on the elevator door. After that, in the opening direction of the active fan of the elevator door, a human force of 150 N is applied to a most unfavorable point. This force is applied along the opening direction of the door and remains constant until the door leaf starts to move or meets the test requirements. Then, slide a set of pointers 4 so that the set of pointers 4 slide on one side of a set of elevator doors respectively, thereby measuring the gap between the set of elevator doors, enabling the staff to read the measurement value on the scale 3. After the measurement, slide the depth gauge 6 so that the depth gauge 6 slides along the rectangular cylinder 5, making the bottom end of the depth gauge 6 in close contact with the elevator door. Then, the value on the depth gauge 6 can be read. After the measurement, the device can be removed from the elevator door. Through the settings of the scale 3 and the depth gauge 6, the gap between the elevator doors and the flatness between the two elevator doors can be measured more quickly, and the measurement efficiency is relatively high. At the same time, the positioning mechanism positions the support plate 1 to ensure that it will not be skewed when fixed on the elevator door, which is beneficial to subsequent measurement operations.

[0031] In a further preferred embodiment of the present invention, a fixing plate 7 is provided on the support plate 1. A connecting cylinder 8 is fixedly installed on the fixing plate 7. A suction cup 9 is assembled at the bottom of the connecting cylinder 8. The suction cup 9 is communicated with the connecting cylinder 8. A handle is installed on the support plate 1.

[0032] In this embodiment, when fixing the support plate 1, first hold the handle, and then adsorb the suction cup 9 on the elevator door, so as to ensure the stability of the support plate 1 on the elevator door and facilitate subsequent use. By adsorbing the suction cup 9 on the elevator door, the support plate 1 is further fixed, and the fixing is relatively fast.

[0033] In a further preferred embodiment of the present invention, a sealing plate 10 is slidably provided in the connecting cylinder 8. A sealing ring is sleeved on the sealing plate 10. A screw rod 11 is threadedly installed at the top of the connecting cylinder 8. The bottom end of the screw rod 11 is connected to the sealing plate 10.

[0034] In this embodiment, after adsorbing the suction cup 9 on the elevator door, rotate the screw rod 11 to drive the sealing plate 10 to slide, and make the sealing plate 10 slide along the connecting cylinder 8, so as to make the sealing plate 10 extract the air in the suction cup 9, thereby increasing the suction force of the suction cup 9, which is beneficial to improving the fixing operation of the support plate 1. At the same time, when it is necessary to remove the support plate 1 from the elevator door, rotate the screw rod 11 to drive the sealing plate 10 to slide down, so as to convey the air in the connecting cylinder 8 to the suction cup 9, facilitating the suction cup 9 to disengage from the elevator door. By extracting the air in the suction cup 9 through the sealing plate 10, the suction force of the suction cup 9 can be effectively enhanced, which is further beneficial to the fixing of the support plate 1.

[0035] In a further preferred embodiment of the present invention, a connecting port 12 is provided on the connecting plate 2 , a fixing block 13 is slidably installed in the connecting port 12 , and the fixing block 13 is fixedly connected to the pointer 4 .

[0036] In this embodiment, when moving the pointer 4, the fixed block 13 is first moved so that the fixed block 13 drives the pointer 4 to slide along the connecting port 12, thereby ensuring that the pointer 4 slides smoothly, which is convenient for measuring the gap of the elevator door. The fixed block 13 slides along the connecting port 12, thereby guiding the pointer 4 to ensure its smooth movement, which is convenient for measuring the gap of the elevator door.

[0037] In a further preferred embodiment of the utility model, the positioning mechanism includes: a guide rod 14 fixedly mounted on the top of the support plate 1; a guide block 15 slidably mounted on the guide rod 14, and the guide block 15 is in sliding contact with the support plate 1; an L-shaped plate 16 fixedly mounted on the bottom of the guide block 15, and the L-shaped plate 16 is in sliding contact with one side of the support plate 1; and a screw block 17 threadedly mounted on the guide block 15.

[0038] In this embodiment, before fixing the support plate 1, the support plate 1 is first placed on one side of the elevator door, and then a set of guide blocks 15 are slid to one end of the guide rod 14 to move the L-shaped plate 16, and then the guide block 15 is fixed using the screw block 17. After fixing, the L-shaped plate 16 is set at the same level as one side of the elevator door to ensure that the support plate 1 will not be skewed. After that, the suction cup 9 can be adsorbed on the elevator door, which is beneficial to the subsequent measurement of the elevator door gap. By setting the L-shaped plate 16 horizontally with one side of the elevator door, it is ensured that the support plate 1 will not be skewed, which is beneficial to improve the measurement accuracy of the elevator door gap.

[0040] In this embodiment, when measuring the flatness between two elevator doors, the depth gauge 6 slides along the rectangular tube 5. When the depth gauge 6 slides, the slide bar 18 slides along the slider 19, thereby guiding the depth gauge 6 to slide and ensure that the depth gauge 6 does not separate from the rectangular tube 5. The slide bar 18 slides along the slider 19, thereby guiding the depth gauge 6 to ensure its smooth movement, which is beneficial to the flatness measurement operation of the elevator door by the depth gauge 6, and can also ensure that the depth gauge 6 does not separate from the rectangular tube 5.

[0041] In a further preferred embodiment of the present utility model, a limiting block 20 is fixedly installed on one side of the fixing plate 7. The limiting block 20 is slidably connected to the card slot of the support plate 1. A positioning rod 21 is slidably installed on the support plate 1, and the positioning rod 21 slidably penetrates through the limiting block 20.

[0042] In this embodiment, when the suction cup 9 is damaged after long-term use, first remove the positioning rod 21 from the support plate 1 to make the positioning rod 21 disengage from the limiting block 20. Then, the fixing plate 7 can be removed from the support plate 1 to make the limiting block 20 slide out of the card slot, and the suction cup 9 can be replaced. The limiting plate 20 is limited by the positioning rod 21, so that the fixing plate 7 is stable, which is convenient for quickly loading and unloading the suction cup 9 and also convenient for replacing the suction cup 9 subsequently.

[0043] In a further preferred embodiment of the present utility model, an installation groove is formed on one side of the positioning rod 21. A return spring is fixedly installed in the installation groove. One end of the return spring is fixedly installed with a positioning block 22.
