[0001] The utility model relates to the technical field of elevator door hanging plates, in particular to an elevator door hanging plate with a noise reduction function. Background Art

[0002] The elevator door hanging plate is a component on the elevator. It is mainly used to control the opening and closing of the elevator door. It plays a guiding and transmission role. By driving the hanging plate through the moving parts, the elevator door can be opened and closed stably, and it can also effectively prevent the elevator waiting personnel from falling off the ladder or shearing accidents.

[0003] The elevator door hanging plate with noise reduction function provided by publication number "CN217458396U" includes a middle frame and an outer frame. The middle frame is movably connected to the elevator door by rolling. Sound insulation layers are arranged inside the middle frame and the outer frame. The outer frame is fixedly connected to the outside of the middle frame. The lower edges of the two side walls of the middle frame are bent inward to form a horizontal part, and the horizontal part is bent upward to form a vertical part. The vertical part is provided with a rotating hole, and the middle frame is movably connected to a roller through the rotating hole. The device converts the relative movement between the elevator door and the hanging plate from sliding to rolling, thereby reducing the friction between the moving parts, thereby reducing the generation of noise, and at the same time reducing the consumption of lubricating oil and extending the maintenance circumference; by arranging a sound insulation layer inside the elevator door hanging plate, the propagation of noise is further hindered, so that the elevator door hanging plate can achieve a better low-noise working state;

[0004] However, the above device still has the following problems during implementation:

[0005] However, considering that there will be a lot of noise during the opening and closing process of the elevator, the main reason is the contact between the hanging plate roller and the guide rail on the elevator door hanging plate, which will affect the feeling of people riding the elevator and reduce the comfort of riding the elevator. Utility Model Content

[0006] The purpose of the utility model is to provide an elevator door hanging plate with noise reduction function to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An elevator door hanging plate with a noise reduction function comprises an elevator door hanging plate and two hanging plate rollers, wherein the hanging plate roller is rotatably connected to one side of the elevator door hanging plate through a rotating shaft, and a noise reduction mechanism is arranged on one side of the elevator door hanging plate to absorb the noise generated by the hanging plate roller contacting with a guide rail;

[0009] The noise reduction mechanism comprises two shields movably arranged on one side of the elevator door hanging plate, a sound insulation cotton block is arranged inside the shield, a sliding block is fixedly connected to one side of the shield, and a sliding groove used in conjunction with the sliding block is opened on one side of the elevator door hanging plate;

[0011] By setting up a noise reduction mechanism, the guide rail and the hanging plate roller can be wrapped by two isolation covers. When the hanging plate roller rolls and contacts the guide rail to generate noise diffusion, the noise waves will enter the sound insulation cotton block to achieve the noise reduction effect. At the same time, the noise reduction grooves opened on the sound insulation cotton block can also increase the area for absorbing noise. At the same time, the sound insulation cotton strips will repeatedly refract the noise waves, making the noise waves transmit farther, thereby achieving the noise reduction effect.

[0012] Preferably, the opening and closing mechanism includes a linkage block fixedly connected to one side of the sliding block, one side of the linkage block is threadedly connected to two threaded rods, one side of the threaded rod is fixedly connected to a clamping block, and one side of the linkage block is provided with a threaded hole for use with the threaded rod.

[0013] By setting up an opening and closing mechanism, when it is necessary to install the hanging plate roller on the elevator door hanging plate on the guide rail, by rotating the twisting block, the two partitions can be unfolded in cooperation with the opening and closing mechanism to leave space for installing the guide rail. After the installation is completed, the position of the partition can be moved to be close to the guide rail without affecting the operation between the hanging plate roller and the guide rail. Then the twisting block is twisted in the reverse direction, and the twisting block drives the threaded rod to rotate in the threaded hole, which will cause the threaded rod to drive the clamping block and the anti-skid pad to move, so that the anti-skid pad fits tightly to the surface of the elevator door hanging plate, thereby completing the restriction on the structure such as the partition, thereby achieving the effect of facilitating installation.

[0014] Preferably, a pressing mechanism is provided at the bottom of the hanging plate roller for improving the matching accuracy between the hanging plate roller and the guide rail;

[0015] The pressing mechanism includes a pressing roller movably arranged at the bottom of the hanging plate roller, one side of the pressing roller is rotatably connected with a bolt through a rotating shaft, one side of the elevator door hanging plate is provided with a moving groove used in conjunction with the bolt, and the surface of the bolt is threadedly connected with a screw sleeve.

[0016] By setting up the pressing mechanism, after the guide rail and the hanging plate roller are installed, the position of the pressing roller can be adjusted so that the pressing roller and the bottom of the guide rail are fitted together, so that the hanging plate roller and the pressing roller clamp the guide rail therebetween, thereby improving the fitting accuracy and effectively reducing the generation of noise.

[0017] Preferably, a twisting block is fixedly connected to one side of the threaded rod, and protrusions are fixedly connected to both sides of the twisting block.

[0018] By providing the twisting block and the protrusion, a lever point can be provided for the user to twist the threaded rod, so that the user can conveniently rotate the threaded rod to move it.

[0019] Preferably, a non-slip pad is fixedly connected to one side of the pressing block, and the material of the non-slip pad is rubber.

[0020] By providing an anti-slip pad, the friction force when the clamping block contacts the elevator door hanging plate can be increased, thereby improving the stability of the partition cover positioning.

[0021] Preferably, two dovetail blocks are fixedly connected to one side of the partition cover, and a dovetail groove used in conjunction with the dovetail blocks is provided on one side of the elevator door hanging plate.

[0022] By arranging the dovetail block and the dovetail groove, the partition cover can be supported, and at the same time the partition cover is restricted to move only along the tracks of the dovetail block and the dovetail groove.

[0023] Preferably, a plurality of noise reduction grooves are provided on one side of the sound insulation cotton block, and a plurality of sound insulation cotton strips are fixedly connected to the inner wall of the noise reduction groove.

[0024] By setting up noise reduction grooves and sound insulation strips, the noise absorption area can be increased. At the same time, the sound insulation strips can also refract sound waves repeatedly, making the noise sound waves transmit farther and improving the noise reduction effect.

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] 1. The utility model is provided with a noise reduction mechanism, which can wrap the guide rail and the hanging plate roller through two isolation covers. When the hanging plate roller rolls and contacts the guide rail to generate noise diffusion, the noise sound waves will enter the interior of the sound insulation cotton block to achieve the effect of noise reduction. At the same time, the noise reduction grooves 20 provided on the sound insulation cotton block can also increase the area for absorbing noise. At the same time, the sound insulation cotton strips will repeatedly refract the noise sound waves, making the noise sound waves transmit farther, thereby achieving the effect of noise reduction.

[0027] 2. The utility model is provided with an opening and closing mechanism. When it is necessary to install the hanging plate roller on the elevator door hanging plate on the guide rail, the two partitions can be unfolded by rotating the twisting block in cooperation with the opening and closing mechanism to leave space for installing the guide rail. After the installation is completed, the position of the partition can be moved to be close to the guide rail without affecting the operation between the hanging plate roller and the guide rail. Then the twisting block is twisted in the reverse direction. The twisting block drives the threaded rod to rotate in the threaded hole, which will cause the threaded rod to drive the clamping block and the anti-skid pad to move, so that the anti-skid pad fits tightly to the surface of the elevator door hanging plate, thereby restricting the structure of the partition and so on, thereby achieving the effect of facilitating installation.

[0028] 3. The utility model is provided with a pressing mechanism, which can adjust the position of the pressing roller after the guide rail and the hanging plate roller are installed, so that the pressing roller and the bottom of the guide rail are fitted together, and the hanging plate roller and the pressing roller clamp the guide rail therebetween, thereby improving the fitting accuracy and effectively reducing the generation of noise.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0039] Embodiment 1:

[0040] An elevator door hanging plate with a noise reduction function comprises an elevator door hanging plate 1 and two hanging plate rollers 2, wherein the hanging plate rollers 2 are rotatably connected to one side of the elevator door hanging plate 1 through a rotating shaft, and a noise reduction mechanism is arranged on one side of the elevator door hanging plate 1 to absorb the noise generated by the hanging plate rollers 2 contacting with the guide rails;

[0041] The noise reduction mechanism includes two shields 3 movably arranged on one side of the elevator door hanging plate 1, a sound insulation cotton block 4 is arranged inside the shield 3, a sliding block 5 is fixedly connected to one side of the shield 3, and a sliding groove 6 used in conjunction with the sliding block 5 is opened on one side of the elevator door hanging plate 1;

[0042] The opening and closing mechanism is fixedly arranged on one side of the sliding block 5 and can control the opening and closing of the two partition covers 3.

[0043] In this embodiment, it is taken into consideration that there will be relatively large noise during the opening and closing process of the elevator. The main reason is that the hanging plate roller 2 on the elevator door hanging plate 1 is in contact with the guide rail, which will affect the feeling of the people riding the elevator and reduce the comfort of riding the elevator. Therefore, by setting a noise reduction mechanism, the guide rail and the hanging plate roller 2 can be wrapped by two partition covers 3. When the hanging plate roller 2 rolls and contacts the guide rail to generate noise diffusion, the noise sound waves will enter the sound insulation cotton block 4 to achieve the effect of noise reduction. At the same time, the noise reduction grooves 20 opened on the sound insulation cotton block 4 can also increase the area of ​​noise absorption. At the same time, the sound insulation cotton strips 21 will also repeatedly refract the noise sound waves, so that the noise sound waves are transmitted over a longer distance, thereby achieving the effect of noise reduction.

[0044] Preferably, a plurality of noise reduction grooves 20 are opened on one side of the sound insulation cotton block 4, and a plurality of sound insulation cotton strips 21 are fixedly connected to the inner wall of the noise reduction groove 20.

[0045] In this embodiment, by providing the noise reduction groove 20 and the sound insulation cotton strip 21, the noise absorption area can be increased by providing the noise reduction groove 20. At the same time, the sound insulation cotton strip 21 can also refract the sound waves repeatedly, so that the noise sound waves are transmitted farther, thereby improving the noise reduction effect.

[0046] Embodiment 2:

[0047] On the basis of Example 1, the sound insulation mechanism in this embodiment can achieve the sound insulation effect by wrapping the hanging plate roller 2 with the sound insulation cotton block 4, but when the sound insulation cotton block 4 wraps the hanging plate roller 2, it is difficult to install the hanging plate roller 2 on the guide rail. The opening and closing mechanism in this application includes a linkage block 7 fixedly connected to one side of the sliding block 5, one side of the linkage block 7 is threadedly connected to two threaded rods 8, one side of the threaded rod 8 is fixedly connected to a clamping block 9, and one side of the linkage block 7 is provided with a threaded hole 10 used in conjunction with the threaded rod 8.

[0048] In this embodiment, it is considered that the sound insulation cotton block 4 wraps the hanging plate roller 2, which makes it difficult to install the hanging plate roller 2 on the guide rail. Therefore, by setting an opening and closing mechanism, when it is necessary to install the hanging plate roller 2 on the elevator door hanging plate 1 on the guide rail, by rotating the twisting block 15, the twisting block 15 drives the threaded rod 8 to rotate in the threaded hole 10, which will cause the threaded rod 8 to drive the pressing block 9 and the anti-slip pad 17 to leave the surface of the elevator door hanging plate 1, thereby releasing the restriction on the sliding block 5 and the partition cover 3. Figure 4 As shown, the position of the partition 3 is then adjusted along the trajectory of the dovetail block 18 and the dovetail groove 19 to unfold the two partitions 3 and leave space for installing the guide rail. After the installation is completed, the position of the partition 3 is moved again to make it close to the guide rail without affecting the operation between the hanging plate roller 2 and the guide rail. The twisting block 15 is then reversed, and the twisting block 15 drives the threaded rod 8 to rotate in the threaded hole 10, which will cause the threaded rod 8 to drive the clamping block 9 and the anti-skid pad 17 to move, so that the anti-skid pad 17 is tightly attached to the surface of the elevator door hanging plate 1, completing the restriction on the structure of the partition 3, thereby achieving the effect of facilitating installation.

[0049] Preferably, a twisting block 15 is fixedly connected to one side of the threaded rod 8 , and protrusions 16 are fixedly connected to both sides of the twisting block 15 .

[0050] In this embodiment, the twisting block 15 and the protrusion 16 are provided to provide a lever point for the user to twist the threaded rod 8, so that the user can easily rotate the threaded rod 8 to move it.

[0051] Preferably, one side of the pressing block 9 is fixedly connected with an anti-skid pad 17 , and the material of the anti-skid pad 17 is rubber.

[0052] In this embodiment, the anti-slip pad 17 is provided to increase the friction force when the pressing block 9 contacts the elevator door hanging plate 1, thereby improving the stability of the positioning of the partition cover 3.

[0053] Preferably, two dovetail blocks 18 are fixedly connected to one side of the partition cover 3 , and a dovetail groove 19 for use with the dovetail blocks 18 is provided on one side of the elevator door hanging plate 1 .

[0054] In this embodiment, the dovetail block 18 and the dovetail groove 19 are provided to support the partition cover 3 , and at the same time, the partition cover 3 is restricted to move only along the track of the dovetail block 18 and the dovetail groove 19 .

[0055] Embodiment three:

[0056] On the basis of the first embodiment, the sound insulation mechanism in this embodiment can achieve the effect of sound insulation by wrapping the hanging plate roller 2 with the sound insulation cotton block 4, but if the installation accuracy of the guide rail and the hanging plate roller 2 is low, it will also cause a large noise. In this application, the bottom of the hanging plate roller 2 is provided with an upward pressure mechanism for improving the matching accuracy between the hanging plate roller 2 and the guide rail;

[0057] The pressing mechanism includes a pressing roller 11 movably arranged at the bottom of the hanging plate roller 2, one side of the pressing roller 11 is rotatably connected to a bolt 12 through a rotating shaft, one side of the elevator door hanging plate 1 is provided with a moving groove 13 used in conjunction with the bolt 12, and the surface of the bolt 12 is threadedly connected with a screw sleeve 14.

[0058] In this embodiment, it is considered that if the guide rail and the hanging plate roller 2 are installed with low accuracy, it will also cause a large noise. Therefore, by setting the upper pressing mechanism, after the guide rail and the hanging plate roller 2 are installed, the position of the upper pressing roller 11 can be adjusted to make the upper pressing roller 11 fit with the bottom of the guide rail, so that the hanging plate roller 2 and the upper pressing roller 11 clamp the guide rail therein, thereby improving the fitting accuracy and effectively reducing the noise.

[0059] The solution is to consider that if the guide rail and the hanging plate roller 2 are installed with low accuracy, it will also cause the problem of generating large noise.

[0060] Working principle: When the elevator door hanging plate 1 needs to be installed on the guide rail, by rotating the twisting block 15, the twisting block 15 drives the threaded rod 8 to rotate in the threaded hole 10, which will cause the threaded rod 8 to drive the pressing block 9 and the anti-slip pad 17 to leave the surface of the elevator door hanging plate 1, thereby releasing the restriction on the sliding block 5 and the partition cover 3. Figure 4 As shown, the position of the partition 3 is then adjusted along the track of the dovetail block 18 and the dovetail groove 19, so that the two partitions 3 are unfolded, leaving space for installing the guide rail. After the installation is completed, the position of the partition 3 is moved again to make it close to the guide rail without affecting the operation between the hanging plate roller 2 and the guide rail. Then the twisting block 15 is reversely twisted, and the twisting block 15 drives the threaded rod 8 to rotate in the threaded hole 10, which will cause the threaded rod 8 to drive the pressing block 9 and the anti-skid pad 17 to move, so that the anti-skid pad 17 is tightly attached to the surface of the elevator door hanging plate 1, completing the restriction of the partition 3 and other structures, thereby achieving the effect of facilitating installation;

[0061] After the guide rail and the hanging plate roller 2 are installed, the upper pressing roller 11 is adjusted in position to fit the upper pressing roller 11 with the bottom of the guide rail, so that the hanging plate roller 2 and the upper pressing roller 11 clamp the guide rail therebetween, thereby improving the fitting accuracy and effectively reducing the noise generation;

[0062] When the hanging plate roller 2 rolls and contacts the guide rail to generate noise diffusion, the noise waves will enter the sound insulation cotton block 4 to achieve the effect of noise reduction. At the same time, the noise reduction grooves 20 opened on the sound insulation cotton block 4 can also increase the area of ​​noise absorption. At the same time, the sound insulation cotton strips 21 will also repeatedly refract the noise waves, making the noise waves transmit farther, thereby achieving the effect of noise reduction.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
