[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Such as Figures 1-3As shown in the figure, an elevator car door quality detection device includes a detection device main body 1. Before detecting the car door 5, the car door 5 is pulled to slide within the fixed track 8 to adjust the position of the car door 5 within the fixed track 8 until one side of the car door 5 abuts against the rubber block 23. The rubber block 23 can effectively protect the car door 5 and prevent the car door 5 from colliding with the fixed plate 9, which may affect the subsequent detection results. After the car door 5 is pulled in place, the pressure plate 11 is driven to press against the outer side of the car door 5 by tightening the first fastening bolt 10 to fix the position of the car door 5 within the fixed track 8. The fixed track 8 and the fixed frame 4 cooperate to simulate the exposed area of the car door 5 during actual use, facilitating the subsequent comprehensive detection of the exposed part of the car door 5. The detection is closer to the actual use situation, and the detection results are more reliable.

[0023] When detecting the left and right different car doors 5, by sliding the car door 5 within the fixed track 8 and the fixed frame 4, the car door 5 can be freely pushed into any fixed track 8 on both sides of the detection device main body 1. The device can detect the left and right different car doors 5 without flipping, and the operation method is simpler, facilitating the operation of the staff.

[0024] As Figure 2 and Figure 4 shown in the figure, after the car door 5 is fixed, the fixed rod 12 is pulled to drive the sliding plate 20 to drive the ball 21 to roll within the circular chute of the detection device main body 1. The sliding plate 20 strengthens the contact area between the fixed rod 12 and the detection device main body 1, making the fixed rod 12 more stable when moving. Then, the position of the fixed rod 12 on the detection device main body 1 is adjusted. The fixed rod 12 drives the movable sleeve 13 to move. The movable sleeve 13 can slide up and down on the fixed rod 12. The movable sleeve 13 drives the movable ring 15, and the movable ring 15 drives the fixed cylinder 16 to drive the connecting cylinder 17 to drive the lead screw 18 to drive the hammer 19. The hammering detection range of the hammer 19 is more extensive, eliminating the detection dead angle and making the detection more comprehensive.

[0025] When using the hammer 19, the distance between the hammer 19 and the surface of the car door 5 can be adjusted by extending the connecting cylinder 17 and the lead screw 18, enhancing the movable range of the hammer 19. The extension of the connecting cylinder 17 and the lead screw 18 also increases the operable space of the hammer 19, making it more convenient for the staff to use.

[0026] Working principle

[0027] It should be noted that the present utility model is an elevator car door quality detection device. When in use, first pull the car door 5, and the car door 5 slides within the fixed track 8 until one side of the car door 5 abuts against the rubber block 23. At this time, tighten the first fastening bolt 10 to drive the pressing plate 11, and the pressing plate 11 abuts against the outer side of the car door 5. The first fastening bolt 10 drives the pressing plate 11 to press tightly against the outer side of the car door 5, thereby fixing the position of the car door 5 between the fixed tracks 8. At this time, the car door 5 is limited and fixed on one side of the detection device main body 1 by the fixed frame 4 and the fixed track 8. At this time, one side edge of the car door 5 can be detected. When it is necessary to detect the other side edge of the car door 5, loosen the first fastening bolt 10, push the car door 5 to slide within the fixed track 8 until the car door 5 reaches the inside of the car door 5 on the other side of the detection device main body 1, and then repeat the above steps to fix the car door 5 to achieve the purpose of detecting both side edges of the car door 5.

[0028] After the car door 5 is fixed, loosen the limit bolt 22, and the limit bolt 22 no longer abuts against the circular chute of the detection device main body 1. At this time, pull the fixed rod 12 to drive the slide plate 20 to drive the ball 21 to roll within the circular chute of the detection device main body 1, adjust the position of the fixed rod 12 on the detection device main body 1, pull the fixed rod 12 to one side of the position where the car door 5 is placed at this time, and then tighten the limit bolt 22 to fix the position of the fixed rod 12. Then, according to the position of the hammer 19 from the surface of the car door 5 at this time, rotate the lead screw 18 and the connecting cylinder 17. The lead screw 18 and the connecting cylinder 17 extend out of the connecting cylinder 17 and the fixed cylinder 16 respectively through threads, and adjust the distance between the hammer 19 and the surface of the car door 5 by extending the connecting cylinder 17 and the lead screw 18. After the adjustment is completed, pull the fixed cylinder 16, and the fixed cylinder 16 drives the connecting cylinder 17 to drive the lead screw 18 to drive the hammer 19 to strike the surface of the car door 5, thereby detecting the surface of the car door 5. When detecting the side edge of the car door 5, repeat the above operation. After adjusting the distance between the hammer 19 and the side edge of the car door 5, use the hammer 19 to strike the side edge of the car door 5 again to achieve the purpose of comprehensively detecting the car door 5.

[0029] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
