Description

Technical Field

[0001] The utility model belongs to the technical field of elevator equipment and relates to a double-folded car door with an anti-collision protection function. Background Technique

[0002] A double-folded car door refers to two folding doors arranged at the entrance of an elevator car. Compared with the single-folded door of a traditional elevator, the double-folded door needs to be folded twice during the opening and closing process. This design makes the elevator door occupy less space during opening and closing, especially suitable for places with limited space.

[0003] The Chinese utility model patent with the application number 2020225051395 discloses an elevator double-folded landing door opening safety protection device, including a sill. Two parallel chutes are opened on the upper outer surface of the sill. Anti-detachment components are fixedly connected to both sides inside the two chutes. A side-opening fast door and a side-opening slow door are respectively arranged at the upper ends of the two chutes. Inverted T-shaped sliders are welded on the lower outer surfaces of the side-opening fast door and the side-opening slow door. The inverted T-shaped sliders are slidably matched with the chutes. Through the limiting and buffering effects of the limiting baffle and the limiting spring, the derailment of the inverted T-shaped slider is effectively prevented, so as to solve the problem that when the fast door and the slow door have a large opening size and are collided by an external force, it is easy to cause the slider to derail or even break, affecting the safety of passengers taking the elevator.

[0004] In the above-mentioned prior art, due to the long opening stroke of the fast door and the slow door, compared with the single-folded door of a traditional elevator, foreign objects are more likely to fall into the two parallel chutes. It is necessary to eliminate potential safety hazards in time, and the chutes need to be regularly maintained, cleaned and lubricated. Moreover, the anti-detachment component not only reduces the efficiency of eliminating potential safety hazards, but also increases the difficulty of regular maintenance and cleaning. Therefore, it is necessary to make improvements and enhancements. Content of the Utility Model

DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 , Figure 2 As shown, a double-folding car door with anti-collision protection function includes a sill 1, and the upper end surface of the sill 1 is provided with two mutually parallel slide grooves 11, and the upper ends of the two slide grooves 11 are respectively slidably provided with a shutter 2 and a slow door 3, and the lower ends of the shutter 2 and the slow door 3 are fixedly connected with an inverted T-shaped slider 4 that slides with the slide groove 11, and both sides of the two slide grooves 11 are provided with an anti-slip component 5, and the anti-slip component 5 includes a hinge 51, a limit baffle 52, a buffer spring 53 and an adjustment support plate 54, the hinge 51 is fixedly connected to the inner side wall of the slide groove 11, and the limit baffle 52 is hinged to the inner side wall of the slide groove 11 through the hinge 51, and the lower end of the sill 1 The surface is fixedly connected with a plurality of vertically arranged adjusting columns 6, and an adjusting nut 61 is threadedly connected to the adjusting column 6. The adjusting support plate 54 is slidably connected to the outer side wall of the slide groove 11 and abuts against the adjusting nut 61. There are multiple buffer springs 53. The side wall of the slide groove 11 is provided with a strip sliding hole 12 corresponding to the buffer spring 53 for passing through. The adjusting support plate 54 is provided with a threaded hole 541 corresponding to the buffer spring 53. The aperture of the threaded hole 541 is larger than the diameter of the buffer spring 53. The threaded hole 541 is threadedly connected to the support stud 7. One end of the buffer spring 53 is fixedly connected to the inner side surface of the limit baffle 52, and the other end is sleeved outside the support stud 7.

[0018] In this embodiment, the support studs 7 are rotated to disengage the threaded engagement with the threaded holes 541 and withdrawn from the buffer spring 53, and then the adjustment support plate 54 is pushed to slide upward along the outer wall of the slide slot 11 for a distance, and the adjustment nut 61 is rotated to make it contact with the adjustment support plate 54 again. Since the buffer spring 53 loses the support effect of the support studs 7 and the diameter of the threaded hole 541 is larger than the diameter of the buffer spring 53, the buffer spring 53 can pass through the threaded hole 541. Due to the gravity of the limit baffle 52 and the buffer spring 53, the limit baffle 52 automatically droops and fits the inner wall of the slide slot 11. When foreign matter falls into the slide slot 11, the efficiency of eliminating safety hazards can be effectively improved, and the difficulty of regular maintenance and cleaning can be effectively reduced.

[0019] In this embodiment, the anti - detachment component 5 is also extremely convenient to reinstall. Rotate the adjusting nut 61 again to reset it, and thread several of the support studs 7 back into the threaded holes 541 and make them pass through the buffer springs 53 again to form an elastic support for the limit baffle 52.

[0020] Furthermore, a limit platform 8 that can abut against the outer side surface of the limit baffle 52 is provided on the inner side wall of the sliding groove 11. The limit platform 8 limits the rotation range of the limit baffle 52 to prevent the limit baffle 52 from colliding with the slider 4.

[0021] The cross - section of the adjusting support plate 54 is Z - shaped, and the threaded hole 541 is arranged in the middle of the adjusting support plate 54. When the outer side surface of the limit baffle 52 abuts against the limit platform 8, the limit baffle 52 is parallel to the middle of the adjusting support plate 54, making the elastic support structure between the limit baffle 52 and the adjusting support plate 54 more stable, and thus playing a better buffering role.

[0022] Furthermore, a limiting portion 542 that can abut against the support stud 7 is provided on the adjusting support plate 54. The limiting portion 542 limits the movement range of the support stud 7 in the threaded hole 541 to prevent the support stud 7 from accidentally coming out and entering the space between the outer side wall of the sliding groove 11 and the adjusting support plate 54.

[0023] Furthermore, the center - to - center distance between the two sliding grooves 11 is greater than or equal to 45 mm. When the center - to - center distance between the two sliding grooves 11 is too small, the installation space of the anti - detachment component 5 between the two sliding grooves 11 will be too restrictive, making it more difficult for the maintenance personnel to adjust the support stud 7 and the adjusting nut 61 at this position.

[0024] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
