Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Referring to fig. 1 to 3, the utility model discloses a following technical scheme, an elevator anti-pinch device, including sedan-chair door 1:

the car door 1 comprises two door bodies which are linearly arranged from left to right, a plurality of grid grooves 2 are correspondingly arranged on one side close to the two door bodies from top to bottom, two sliding chutes 4 which are arranged in parallel from top to bottom are arranged on the inner wall of the side far away from the grid grooves 2 at the left end and the right end, sliding plates 5 are connected in the sliding chutes 4 in a sliding way, the sliding chutes 4 extend into the interior of the door body, the height of the inner sides of the sliding chutes 4 is larger than that of the outer sides, the sections of the sliding plates 5 are L-shaped, the sliding chutes 4 extend out of the outer ends of the sliding plates 5 to be connected with a fixed frame 3, a central shaft is fixed in the middle of the inner sides of the fixed frame 3, rubber rollers 7 are arranged around the outer sides of the central shaft, ball bearings are communicated and fixed in the middle of the rubber rollers 7, the rubber rollers 7, a spring groove 8 is formed in the lower portion of the front side of the fixing frame 3, which is far away from the sliding plate 5, an inclined block 9 is inserted in the spring groove 8, a spiral spring is fixed between the spring groove 8 and the inclined block 9, the inclined block 9 is elastically connected with the spring groove 8 through the spiral spring, a jack is formed in the front side of the inclined block 9 in a penetrating mode, an infrared detector 10 is embedded and fixed in the jack, an inclined surface is arranged at one end, close to the sliding plate 5, of the inclined block 9, a proximity switch is fixed at the rear end of the infrared detector 10 and is located on the inner wall of the spring groove 8, and the;

when two door bodies of the car door 1 approach to each other in the closing process, two rubber rollers 7 on the same horizontal line are gradually pressed from contact to each other, so that the fixing frame 3 is pushed to compress the pressure spring 6, the fixing frame 3 moves to drive the sliding plate 5 to horizontally slide by taking the sliding groove 4 as a track, the horizontal stability of the moving process of the fixing frame 3 is kept, the sliding groove 4 extends into the door body, the height of the inner side of the sliding groove 4 is larger than that of the outer side, the section of the sliding plate 5 is L-shaped, the sliding plate 5 can be prevented from being separated from the sliding groove 4 when the pressure spring 6 is pulled outwards, the completeness of a keeping device is facilitated, when a person rushing to take an elevator has the situation that hands stretch to block the car door to be closed, fingers are easily clamped in the rubber rollers 7 made of rubber materials, the rubber is easy to deform, the pain feeling of clamping can be relieved, meanwhile, the rubber rollers, the friction resistance generated by the rotation of the rubber roller 7 can be reduced, the resistance when the clamped person directly takes out the fingers is reduced, the clamped person is not easy to be injured, and the clamped objects can be quickly taken out from the rubber roller 7 in the same way, so that accidents are prevented;

further, the fixing frame 3 moves towards the grid groove 2 under the pushing of the rubber roller 7 in the closing process of the car door 1, at the moment, because the fixing frame 3 is equal to the grid groove 2 in height and consistent in width, the outer wall of the front side of the fixing frame 3 is in contact with the inner wall of the grid groove 2, the inclined plane of one end, close to the sliding plate 5, of the inclined block 9 is extruded by the inner wall of the grid groove 2, then the spiral spring is compressed, the inclined block 9 moves towards the inside of the spring groove 8, the infrared detector 10 in the jack moves towards the inner wall of the spring groove 8 along with the movement of the inclined block 9 to generate displacement, the proximity switch is triggered, the infrared detector 10 is controlled to work through signal connection, temperature detection is carried out in a certain range in front of the car door 1, when a person catching up with the elevator does not completely block the infrared detector 10 on the inner wall of the grid groove 2 and stands in the detection range, therefore, the car door 1 is prevented from being closed, and the car door 1 does not need to be prevented from being closed in a mode of shielding by an outsourcing hand, so that the elevator is safer to use.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
