Description

Technical Field

[0001] The utility model relates to the technical field of automobile part processing, in particular to a sound-absorbing cotton fixing frame. Background Art

[0002] In modern automobile manufacturing, noise control has become an important link in improving vehicle comfort and performance. Among them, the application of automobile sound-absorbing cotton is particularly common. The sound-absorbing cotton absorbs and reduces the noise generated by the engine, tires and the road surface, etc., effectively reducing the noise level during vehicle operation, thereby providing a quieter riding environment for drivers and passengers. In order to enable the sound-absorbing cotton to exert its best performance, it is particularly important to design a reasonable fixing frame.

[0003] In the prior art, the sound-absorbing cotton needs to be fixed on the automobile through a fixing frame to reduce the transmission of noise during vehicle operation. However, most of the sound-absorbing cotton fixing frames are fixed by welding, resulting in inconvenient quick disassembly and installation of the sound-absorbing cotton when it is wet or damaged, thus seriously affecting the maintenance or replacement efficiency of the sound-absorbing cotton and increasing the labor intensity of the staff. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem of low efficiency in maintaining or replacing the sound-absorbing cotton due to the inability to quickly disassemble and install the sound-absorbing cotton when the above equipment is in use, and thus a sound-absorbing cotton fixing frame is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a sound-absorbing cotton fixing frame, including a fixing frame, an installation frame is movably embedded on the inner surface wall of the fixing frame, four square grooves are opened at the top of the installation frame, limiting springs are arranged on the inner surface walls of the four square grooves, limiting shafts are movably embedded on the inner surface walls of the four square grooves, and one side of the outer wall of the limiting shaft is fixedly connected with one side of the outer wall of the limiting spring. Two installation grooves are opened at the top of the installation frame, compression springs are arranged on the inner surface walls of the two installation grooves, limiting blocks are movably embedded on the inner surface walls of the two installation grooves, and one side of the outer wall of the limiting block is fixedly connected with one side of the outer wall of the compression spring. Two limiting grooves are opened on the outer surface wall of the fixing frame.

[0006] Preferably, installation blocks are fixedly installed at the bottom of the inner walls of the two limiting grooves, and wedge-shaped blocks are movably sleeved on the outer surface walls of the two installation blocks.

[0007] Preferably, return springs are arranged on the outer surface walls of the two installation blocks, and the return springs are arranged inside the wedge-shaped blocks.

[0008] Preferably, a sound-absorbing cotton main body is fixedly installed on the inner surface wall of the installation frame.

[0009] Preferably, an installation frame is movably sleeved on the outer surface wall of the fixing frame. Four buffer springs are fixedly installed at the bottom of the inner wall of the installation frame, and the top of the buffer spring is fixedly connected to the top of the fixing frame.

[0010] Preferably, dampers are arranged on the inner surface walls of the four buffer springs.

[0011] Preferably, a fixing bolt is movably inserted into the inner surface wall of the installation frame, and a dust-proof net is fixedly installed on the inner surface wall of the installation frame.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] During the use of the present utility model, through the interaction of a series of components, when the automotive sound-absorbing cotton is damaged after long-term use and needs to be disassembled and replaced, first, under the operation of the staff, the wedge-shaped block is pressed to rotate a certain angle around the round shaft of the installation block, and it no longer plays a role in fixing and limiting the limiting block. Then, the limiting block is pressed to move towards the middle inside the installation groove, and at the same time, the limiting shaft is pressed to move towards the middle inside the square groove, so that neither the limiting block nor the limiting shaft plays a role in fixing and limiting the installation frame and the fixing frame, thereby completing the rapid disassembly of the sound-absorbing cotton, facilitating the staff to repair and replace it, improving the maintenance or replacement efficiency, and reducing the labor intensity of the staff.

[0014] During the use of the present utility model, through the interaction of a series of components, during the use of the automotive sound-absorbing cotton, since the vehicle will generate vibrations during movement, at this time, under the action of the buffer springs and dampers, it can play a buffering role for the sound-absorbing cotton and the sound-absorbing cotton frame, avoiding damage to it due to long-term vibrations, thereby playing a protective role for the sound-absorbing cotton frame and extending its service life. And under the action of the dust-proof net, it can prevent a large amount of external dust from adhering to the sound-absorbing cotton, thereby improving the use effect of the sound-absorbing cotton.

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As Figures 1 - 5 shown, the present utility model provides a sound-absorbing cotton fixing frame, including a fixing frame 1. The inner wall of the fixing frame 1 is movably embedded with a mounting frame 6. Four square grooves 7 are opened at the top of the mounting frame 6. Limiting springs 8 are arranged on the inner walls of the four square grooves 7. Limiting shafts 9 are movably embedded in the inner walls of the four square grooves 7. One side of the outer wall of the limiting shaft 9 is fixedly connected to one side of the outer wall of the limiting spring 8. Two mounting grooves 10 are opened at the top of the mounting frame 6. Compression springs 11 are arranged on the inner walls of the two mounting grooves 10. Limiting blocks 12 are movably embedded in the inner walls of the two mounting grooves 10. One side of the outer wall of the limiting block 12 is fixedly connected to one side of the outer wall of the compression spring 11. Two limiting grooves 13 are opened on the outer wall of the fixing frame 1. Mounting blocks 14 are fixedly installed at the bottom of the inner walls of the two limiting grooves 13. Wedge blocks 15 are movably sleeved on the outer walls of the two mounting blocks 14. Return springs 16 are arranged on the outer walls of the two mounting blocks 14. The return spring 16 is arranged inside the wedge block 15. The sound-absorbing cotton body 17 is fixedly installed on the inner wall of the mounting frame 6.

[0025] The effect achieved by the entire Embodiment 1 is that when the sound-absorbing cotton needs to be disassembled, replaced or maintained, first, under the operation of the staff, the limiting shaft 9 is pressed to move towards the middle inside the square groove 7 and compress the limiting spring 8, so that the limiting shaft 9 no longer plays a role in fixing and limiting the mounting frame 6 and the fixing frame 1. Then, the wedge-shaped block 15 is pressed to rotate a certain angle around the round shaft between the inner surfaces of the mounting block 14 and compress the reset spring 16, so that the wedge-shaped block 15 no longer plays a role in fixing and limiting the limiting block 12. Subsequently, the mounting frame 6 is moved upward, and at the same time, the limiting block 12 is pressed to move towards the middle inside the mounting groove 10 and compress the compression spring 11, so that the limiting block 12 is taken out from the inside of the limiting groove 13, so that the mounting frame 6 can be easily taken out from the inside of the fixing frame 1, and then the rapid disassembly of the sound-absorbing cotton is completed, making it more convenient for the staff to maintain or replace the sound-absorbing cotton and improving the work efficiency.

[0026] Embodiment 2: As Figures 2 - 5 shown, an installation frame 2 is movably sleeved on the outer surface of the fixing frame 1. Four buffer springs 3 are fixedly installed at the bottom of the inner wall of the installation frame 2, and the top of the buffer spring 3 is fixedly connected to the top of the fixing frame 1. A damper 4 is arranged on the inner surface of the four buffer springs 3. A fixing bolt 5 is movably inserted into the inner wall of the installation frame 2. A dust-proof net 18 is fixedly installed on the inner wall of the mounting frame 6.

[0027] The effect achieved by the entire Embodiment 2 is that when the sound-absorbing cotton is in use, due to the vibration generated by the movement of the car, the vibration will be transmitted to the fixing frame 1, causing the fixing frame 1 to vibrate and move inside the installation frame 2. The buffer spring 3 is compressed by the movement of the fixing frame 1. When the buffer spring 3 is compressed to a certain extent, a large restoring force will be generated. At this time, under the action of the damper 4, part of the restoring force generated by the buffer spring 3 can be absorbed, avoiding all the restoring force acting on the fixing frame 1, so as to buffer and damp the vibration of the fixing frame 1, avoid damage to the sound-absorbing cotton frame due to long-term vibration, extend its service life, and under the action of the dust-proof net 18, a large amount of dust or impurities can be prevented from adhering to the outer surface of the sound-absorbing cotton, thereby improving the use effect of the sound-absorbing cotton.

[0028] Working principle: During use, when the automotive sound insulation cotton is damaged after long-term use and needs to be disassembled and replaced, first, under the operation of the staff, the limiting shaft 9 is pressed to move towards the middle inside the square groove 7 and compress the limiting spring 8, so that the limiting shaft 9 no longer plays a role in fixing and limiting the mounting frame 6 and the fixing frame 1. Then, the wedge-shaped block 15 is pressed to rotate a certain angle around the round shaft between the inner surfaces of the mounting block 14 and compress the return spring 16, so that the wedge-shaped block 15 no longer plays a role in fixing and limiting the limiting block 12. Subsequently, the mounting frame 6 is moved upward, and at the same time, the limiting block 12 is pressed to move towards the middle inside the mounting groove 10 and compress the compression spring 11, so that the limiting block 12 is taken out from the inside of the limiting groove 13, and thus the mounting frame 6 can be easily taken out from the inside of the fixing frame 1, thereby completing the rapid disassembly of the sound insulation cotton. When the sound insulation cotton is completed with maintenance or replacement, the sound insulation cotton can be installed and fixed again through the above structure and method for normal use. During the use of the sound insulation cotton, due to the vibration generated by the movement of the vehicle, and the vibration will be transmitted to the fixing frame 1, causing the fixing frame 1 to vibrate and move inside the mounting frame 2. By the movement of the fixing frame 1, the buffer spring 3 is compressed. When the buffer spring 3 is compressed to a certain extent, a large rebound force will be generated. At this time, under the action of the damper 4, part of the rebound force generated by the buffer spring 3 can be absorbed, avoiding all the rebound force acting on the fixing frame 1, thereby buffering and damping the vibration of the fixing frame 1 and preventing the sound insulation cotton frame from being damaged due to long-term vibration. And under the action of the dust-proof net 18, a large amount of dust or impurities can be prevented from adhering to the outer wall of the sound insulation cotton, improving the use effect of the sound insulation cotton.

[0029] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
