Description

Technical Field

[0001] This utility model relates to the field of comb plate technology, specifically to a telescopic device for an anti-tooth-lifting comb plate. Background Technology

[0002] The comb plate is a component located at both ends of the entrance / exit, designed to facilitate passenger transition and engage with steps, treads, or moving walkway belts. Its ends are rounded, and its shape should minimize the risk of foot pinching between the comb plate and the steps, treads, or belts. The support structure should be adjustable to ensure proper engagement and appropriate rigidity. However, in the event of a malfunction, the comb plate may experience tooth warping, which can easily damage other important components. Therefore, an anti-warping comb plate telescopic device is proposed.

[0003] Existing anti-warping comb plate telescopic devices have certain drawbacks. When the device malfunctions, there is no shock absorption treatment. A Chinese patent discloses an "anti-warping comb plate telescopic device" (application number CN202022469695.1), which includes a left fixed tooth plate, a middle movable tooth plate, a right fixed tooth plate, a waterproof strip, a first anchor bolt, a second anchor bolt, and a stainless steel sliding plate. The left fixed tooth plate has a first comb tooth, the middle movable tooth plate has a second and third comb tooth, and the right fixed tooth plate has a fourth comb tooth. A connecting shaft is located below the first comb tooth, and a connecting plate is located below the second comb tooth. The connecting plate has a groove and a third anchor bolt. A connecting hole is opened on the second comb tooth, and a butterfly spring and nut matching the third anchor bolt are installed in the connecting hole. A rubber plate is placed between the second comb tooth and the connecting plate. This multi-directional corner comb plate telescopic device prevents the middle movable tooth plate from warping when the beam plate rotates vertically under gravity, extending the service life of the telescopic device. However, it lacks shock absorption treatment when the device malfunctions.

[0004] Chinese Utility Model Publication No. CN220467268U discloses a telescopic device for an anti-warping comb plate, which includes: two comb plates, a skirt plate fixedly connected to the sides of the two comb plates, a rotating shaft movably connected between the skirt plates, a spring fixedly connected between the comb plates and the skirt plates, a sliding plate slidably connected to the bottom of the comb plates, a baffle plate fixedly connected to one end of the comb plates, and a rubber interlayer fixedly connected to one end of the skirt plates; a front edge plate, a groove formed on the side of the front edge plate near the comb plates, an mounting block fixedly connected to the top of the comb plates, and a safety switch fixedly connected to the side of the front edge plate.

[0005] The device uses springs to cushion the comb plate and skirt plate. However, the springs are fixedly mounted on the comb plate and skirt plate. As springs are precision devices, their elasticity decreases after a period of use, thus reducing their cushioning effect. They need to be replaced regularly by staff. Since they are fixed, they are not easy to disassemble and install, so their practicality is not very good. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the prior art, an anti-warping comb plate telescopic device includes several comb plates 1 and skirt plates 2. The skirt plates 2 are movably connected by a rotating shaft. A sliding plate 3 is slidably connected to the bottom of the comb plate 1. A rubber interlayer 4 is fixedly connected to one end of the skirt plate 2. The rubber interlayer 4 can play a certain buffering role, thereby protecting the skirt plate 2 and the comb plate 1. A light strip is fixedly connected between the skirt plates 2. A pressure sensor is fixedly connected inside the comb plate 1. The pressure sensor is linearly connected to the light strip, which is conducive to the device transmitting information to the light strip according to gravity, so that it lights up and provides illumination for the user. A mounting block is fixedly connected to the side of the comb plate 1. A front edge plate 13 is provided on the other side of the mounting block. A safety switch is fixedly connected to the side of the front edge plate 13, which is conducive to the timely shutdown of the device in case of failure. This is the prior art and will not be elaborated on here.

[0025] Please see Figure 1-3 The present invention provides a telescopic device for preventing tooth warping of a comb plate. The side wall of the comb plate 1 is provided with a mounting seat 5. A gap is provided between the lower part of the mounting seat 5 and the sliding plate 3 to prevent friction between the mounting seat 5 and the sliding plate 3 when the comb plate 1 moves.

[0026] The mounting base 5 has a mounting groove that extends through the top of the mounting base 5. A connecting base 6 is inserted into the mounting groove. The connecting base 6 is inserted into the mounting groove of the mounting base 5 by plugging it in, which facilitates disassembly and installation. A shock-absorbing component is provided at the end of the connecting base 6. The two can be installed together by welding, bonding or integral molding. The other end of the shock-absorbing component abuts against the side wall of the rubber interlayer 4 at the end of the skirt plate 2 on the other side. When the two comb plates 1 move, they drive the skirt plate 2 to move. The skirt plate 2 presses on the shock-absorbing component, compressing the shock-absorbing component and buffering the comb plate 1 and the skirt plate 2.

[0027] The shock absorption assembly includes an outer tube 7 mounted on a connecting base 6. There is a gap between the outer tube 7 and the light strip. A cavity is provided in the middle of the outer tube 7, and one end of the cavity passes through one end of the outer tube 7 to form an installation port.

[0028] A rod 8 is slidably installed inside the cavity of the outer tube 7. One end of the rod 8 is inserted into the cavity through the installation port on one side of the outer tube 7. A spring 9 is installed at the end of the rod 8 inside the cavity, and the other end of the spring 9 is installed on the inner wall of the outer tube 7. When the rod 8 is compressed, it continues to penetrate deeper into the cavity of the outer tube 7, and then compresses the spring 9. The spring 9 pushes the rod 8 to provide a reaction force, which buffers the impact force transmitted from the skirt 2, thereby playing a certain protective role.

[0029] The upper part of the connecting base 6 is provided with a through hole 10, and a bolt 11 is installed through the through hole 10. There is a gap between the bolt 11 and the outer tube 7 to facilitate the installation of the bolt 11 by the staff.

[0030] The side wall of the comb plate 1 is provided with a threaded hole 12, and the threaded hole 12 and the bolt 11 are threaded together. By screwing the bolt 11 into the threaded hole 12 of the comb plate 1, the connecting base 6 can be further fixed on the comb plate 1.

[0031] In summary, when using this anti-warping comb plate telescopic device, the connecting base 6 is inserted into the mounting slot at the top of the mounting base 5 to complete the plug-in installation. Ensure that the shock-absorbing component at the end of the connecting base 6 faces the sidewall of the rubber interlayer 4 at the end of the skirt plate 2. Pass the bolt 11 through the through hole 10 at the top of the connecting base 6, align it with the threaded hole 12 on the sidewall of the comb plate 1, and rotate the bolt 11 clockwise until it is tightly threaded into the threaded hole 12, further securing the connecting base 6. After starting the equipment, the comb plate 1 can slide along the sliding plate 3, driving the skirt plate... When the skirt plate 2 moves, it presses down on the rod 8 of the shock absorber assembly. The rod 8 extends into the cavity of the outer tube 7 and compresses the spring 9. The spring 9 generates a reaction force to buffer the impact force. The rubber interlayer 4 assists in buffering and protects the comb plate 1 and the skirt plate 2. After a period of use, the elasticity of the spring 9 weakens and needs to be replaced. To remove the spring 9, turn the bolt 11 counterclockwise and remove the bolt 11. Then, the connecting base 6 can be pulled off the mounting base 5. After replacing the new connecting base 6 and the shock absorber assembly, the removed shock absorber assembly can be taken to a repair shop for repair.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
