Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation pads, in particular to a high-speed rail door sound insulation pad. Background Art

[0002] Sound insulation pads are used to be installed on high-speed rail doors to reduce the transmission of sound from outside the high-speed rail into the high-speed rail and avoid affecting passengers. Sound insulation pads are usually rubber pads. By installing sound insulation pads on high-speed rail doors, when the high-speed rail door is closed, the sound insulation pads and the door frame are closed, thereby reducing the transmission of sound.

[0003] The inventors have found in their daily work that when the sound insulation pad is used, since the sound insulation pad is installed on the high-speed iron door, the adhesive is generally applied to the sound insulation pad and then installed in the slot on the high-speed iron door to fix the sound insulation pad. However, with the increase of usage time, the viscosity of the adhesive decreases. At the same time, when the high-speed iron door is closed, the sound insulation pad is forced to close with the door frame, further accelerating the separation of the sound insulation pad and the adhesive, so that the sound insulation pad may slip off the high-speed iron door when the high-speed iron door is closed, thereby reducing the service life of the sound insulation pad. Utility Model Content

However, as the use time increases, the viscosity of the adhesive decreases. At the same time, when the high-speed iron door is closed, the sound insulation pad is forced to close with the door frame, which further accelerates the separation of the sound insulation pad and the adhesive. As a result, the sound insulation pad may slip off the high-speed iron door when the high-speed iron door is closed, thereby reducing the service life of the sound insulation pad. A high-speed iron door sound insulation pad is proposed.

[0010] The effect achieved by the above components is that the blocking block can be hooked out by fingers through the operation groove by setting the operation groove.

[0011] Preferably, the four corners of the inner wall of the sound insulation pad are provided with sliding rods, bidirectional threaded cylinders and wind turbines.

[0012] The effect achieved by the above components is: by arranging sliding rods, bidirectional threaded cylinders and wind turbines at the four corners of the inner wall of the sound insulation pad, the sound insulation pad is further squeezed by the extrusion plate.

[0013] Preferably, the threads at both ends of the bidirectional threaded barrel are opposite.

[0014] The effect achieved by the above components is that the bidirectional threaded cylinder rotates, so that the extrusion plate moves on its inner wall under the limitation of the sound insulation pad.

[0015] Preferably, the detection assembly includes a connecting rope fixedly connected to one side of the extrusion plate, the upper end of the connecting rope is fixedly connected to a connecting block, and the upper end of the connecting block is fixedly connected to a measuring rope.

[0016] The effect achieved by the above components is: when detecting the moving distance of the extrusion plate, the extrusion plate moves, causing the connecting rope to move, causing the measuring rope on the connecting block to move downward, and a scale is set on the surface of the measuring rope to detect the moving distance of the extrusion plate.

[0017] Preferably, a spring is fixedly connected to the upper end of the connecting block, and the other end of the spring is fixed to a sound insulation pad.

[0018] The effect achieved by the above components is: the connection block is reset by arranging the spring.

[0019] Preferably, the measuring rope passes through the sound insulation pad.

[0020] The effect achieved by the above components is: by observing the downward movement scale of the measuring rope, the movement distance of the extrusion plate is detected.

[0021] In summary, the beneficial effects of the utility model are:

By setting the extrusion component 2, when installing the sound insulation pad 1 to the high-speed rail door, the sound insulation pad 1 is installed into the installation groove on the high-speed rail door, and the air pump is inserted into the air hole 25, and the air pump is started to inflate the inside of the sound insulation pad 1, so that the wind turbine 24 is blown and rotated by the gas, and the gas emerges from the air hole 25 on the other side, so that the bidirectional threaded cylinder 23 on the sliding rod 22 rotates, so that the extrusion plate 21 moves to both sides, thereby squeezing the sound insulation pad 1 onto the high-speed rail door. On both sides of the inner wall of the installation groove, the sound insulation pad 1 is fixed, and the inner wall of the air hole 25 is provided with a blocking block 26, which is a rubber plug. By setting the blocking block 26, the air hole 25 is blocked, and an operation groove 27 is opened at one end of the blocking block 26. The blocking block 26 is hooked out with a finger with the help of the operation groove 27. By setting the operation groove 27, the blocking block 26 is hooked out with a finger with the help of the operation groove 27. The four corners of the inner wall of the sound insulation pad 1 are provided with sliding rods 22, two-way threaded cylinders 23 and wind turbines 24. By arranging sliding rods 22, two-way threaded cylinders 23 and wind turbines 24 at the four corners of the inner wall of the sound insulation pad 1, the extrusion plate 21 is further squeezed to squeeze the sound insulation pad 1. The threads at both ends of the two-way threaded cylinder 23 are opposite.

[0032] Working principle:

[0033] By installing the sound insulation pad 1 on the high-speed rail door, when the high-speed rail door is closed, the sound insulation pad 1 is closed with the door frame, thereby reducing the sound transmission. When installing the sound insulation pad 1 on the high-speed rail door, the sound insulation pad 1 is installed in the installation groove on the high-speed rail door, and the air pump is inserted into the air hole 25. The air pump is started to inflate the interior of the sound insulation pad 1, so that the wind turbine 24 is blown and rotated by the gas, and the gas emerges from the air hole 25 on the other side, so that the two-way threaded cylinder 23 on the slide rod 22 rotates, so that the extrusion plate 21 moves to both sides, thereby squeezing the sound insulation pad 1 to both sides of the inner wall of the installation groove on the high-speed rail door, thereby fixing the sound insulation pad 1, and the air hole 25 is blocked by setting the blocking block 26, and the operation slot 2 is set 7. The blocking block 26 is hooked out with a finger with the help of the operating groove 27. By setting the sliding rod 22, the bidirectional threaded cylinder 23 and the wind turbine 24 at the four corners of the inner wall of the sound insulation pad 1, the extrusion plate 21 is further squeezed to squeeze the sound insulation pad 1. The bidirectional threaded cylinder 23 rotates, so that the extrusion plate 21 moves on its inner wall under the limit of the sound insulation pad 1. When detecting the moving distance of the extrusion plate 21, the extrusion plate 21 moves, so that the connecting rope 31 moves, and the measuring rope 33 on the connecting block 32 moves downward. The surface of the measuring rope 33 is provided with a scale, so as to detect the moving distance of the extrusion plate 21. By setting the spring 34, the connecting block 32 is reset, and the moving distance of the extrusion plate 21 is detected by observing the downward movement of the measuring rope 33.
