Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention, in particular to a dust-proof mask for car audio. Background Art

[0002] Car audio is a sound receiving and playback device designed to reduce the boredom of drivers and passengers during travel. The earliest car audio system was the AM radio, followed by AM / FM radios and tape players, and later developed into CD players and compatible DCC and DAT digital audio systems.

[0003] In order to increase the service life and not affect the sound quality, existing car audio is equipped with a dust mask. However, most of the existing dust masks are fixed to the outside of the car audio box by bolts, which makes it inconvenient to replace the internal parts of the speaker, resulting in cumbersome disassembly and inconvenient to clean the dust adsorbed on the mesh. Therefore, a dust mask for car audio is needed to solve the above problems. Utility Model Content

[0008] Preferably, the buffer mechanism comprises a connecting plate, the connecting plate is fixedly mounted on the top end of the limiting groove, and a top plate is fixedly mounted on the top end of the connecting plate via a spring.

[0009] Furthermore, a plurality of anti-sliding blocks are fixedly mounted on the outer side wall of the top seat.

[0010] Furthermore, the inner side wall of each slide groove is coated with anti-slip paint.

[0011] Based on the above solution, the top and bottom ends of the dust cover are coated with anti-slip paint.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a dust mask for car audio, which has the following beneficial effects:

[0014] The dust mask for the car audio system effectively protects the top of the audio system from dust through the dust mask, and the dust mask is stably fixed between the support and the top seat by clamping the fixing column and the fixing rod at the bottom of the top seat with the sliding groove on the fixing bin, so that the dust mask can be quickly replaced and the dust adsorbed on the dust mask can be cleaned, thereby ensuring the normal operation of the dust mask and improving practicality.

[0020] 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.

[0021] Example

[0022] See also Figure 1-4A dust mask for a car audio system comprises an audio system body 1 and a top seat 3. A support 2 is fixedly installed on the top of the audio system body 1. A dust cover 4 is tightly fitted on the bottom of the top seat 3. A limiting groove 5 is provided on the top of the support 2. A plurality of fixed bins 6 are fixedly installed on the top of the limiting groove 5. A slide groove 7 is provided at one end of each fixed bin 6. A plurality of fixed columns 8 are fixedly installed on the bottom end of the top seat 3. A fixing rod 9 is fixedly installed on the outer wall of each fixing column 8. Each fixing rod 9 is slidably mounted with the slide groove 7 provided on each fixed bin 6. A buffer mechanism is provided on the top of each limiting groove 5. The buffer mechanism comprises a connecting plate 10. The connecting plate 10 is fixedly installed on the top of the limiting groove 5. A top plate 12 is fixedly installed on the top of the plate 10 by a spring 11. Through the expansion and contraction of the spring 11, the top plate 12 is synchronously driven to fit closely with the bottom end of the top seat 3, thereby improving the stability effect when the support 2 and the top seat 3 are in contact. The dust mask for the car audio effectively prevents dust from the top of the audio body 1 through the dust cover 4. The fixed column 8 and the fixed rod 9 at the bottom of the top seat 3 are clamped with the slide groove 7 on the fixed bin 6, so that the dust cover 4 is stably fixed between the support 2 and the top seat 3, thereby facilitating the rapid replacement of the dust cover 4 and the cleaning of the dust adsorbed on the dust cover 4, thereby ensuring the normal operation of the dust cover 4 and improving practicality.

[0023] See also Figure 1 A plurality of anti-sliding blocks 13 are fixedly mounted on the outer wall of the top seat 3 . By installing the anti-sliding blocks 13 , it is convenient for the user to rotate the top seat 3 .

[0024] See also Figure 3 It should also be noted that the inner wall of each slide groove 7 is coated with an anti-skid coating 14. By coating the anti-skid coating 14, the stability of the fixing rod 9 when it is fixed inside the slide groove 7 is improved.

[0025] The top and bottom ends of the dust cover 4 are coated with anti-skid paint, and the anti-skid paint is applied to improve the stability of the dust cover 4 when it is attached to the top seat 3 and the support seat 2.

[0026] In summary, when the dust mask for car audio is used, the top of the audio body 1 is filtered through the dust cover 4. When the dust cover 4 needs to be replaced, the top seat 3 is rotated through the anti-sliding block 13, so that the fixing rod 9 and the slide groove 7 on the fixing bin 6 are disengaged, and the spring 11 is extended, so that the disengaged fixing rod 9, the fixing column 8 and the top seat 3 are quickly disengaged from the support 2, and the dust cover 4 is disengaged from the bottom of the top seat 3, so that the dust cover 4 is cleaned. After cleaning, the dust cover 4 reverses the above-mentioned operation process, so that the dust cover 4 can be reinstalled between the top seat 3 and the support 2.

[0027] 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.
