Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a quick-release fixing buckle structure for automotive air filters. Background Technology

[0002] The car air filter is an important component of the car engine intake system. Its main function is to filter dust, particles and other impurities in the air, providing clean air to the engine and ensuring its normal operation and service life. The fixing clip structure plays a key role in the installation and maintenance of the car air filter.

[0003] Currently, most common automotive air filter fixing clip structures on the market adopt traditional and simple clip-on methods. Although this simplifies the installation process to some extent, the connection stability of the clips is poor. During vehicle operation, due to factors such as vibration, the clips are prone to loosening or even falling off, leading to a decrease in the sealing performance of the air filter. Unfiltered air from the outside can easily enter the engine intake system, affecting the normal operation of the engine and reducing its performance and lifespan. Therefore, this utility model proposes a quick-release fixing clip structure for automotive air filters to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a quick-release fixing buckle structure for an automotive air filter, including a fixing box 1, which is composed of a bottom protective box 2 and a top sealing cover 3; a filter plate 5 is placed inside the bottom protective box 2, and the top sealing cover 3 is connected to the air pipe 4; a limiting ring 22 is fitted around the bottom protective box 2, with notches at both ends of the limiting ring 22, and limiting latches 23 at both ends of the notches; a positioning ring 31 is fitted around the top sealing cover 3, with cavities 32 at both ends of the positioning ring 31 of the same size as the notches in the limiting ring 22, and two sets of locking blocks 33 are provided in the cavities 32, with the locking blocks 33 extending at both ends. At the upper and lower ends of the cavity 32, the lower end of the locking block 33 is provided with abutment block 34. The two locking blocks 33 are installed in the cavity 32 through guide post 37. At the same time, the guide post 37 passes through the spring 35 connected to the two locking blocks 33. Through the cooperation of the limiting ring 22 and the positioning ring 31, as well as the design of the locking block 33, spring 35 and other components, the quick installation and disassembly of the car air filter fixing box 1 can be realized. Compared with the traditional bolt connection method, no tools are needed, which greatly shortens the installation and disassembly time, improves the efficiency of maintenance, reduces labor costs, and makes it convenient for users to quickly replace and maintain the filter plate 5.

[0023] Please see Figures 1 to 4 One end of the guide post 37 extends to the outside of the cavity 32, and one end of the guide post 37 is threaded. The guide post 37 is installed in the cavity 32 in a spiral manner. The two ends of the spring 35 are connected to the positioning blocks 36. The positioning blocks 36 at both ends are provided with screw holes. The spring 35 is installed on the locking blocks 33 at the left and right ends through the positioning blocks 36. In use, the guide post 37 is installed in the cavity 32 in a spiral manner. This detachable connection method makes it easy to install the guide post 37 into or remove it from the cavity 32 during manufacturing or maintenance. At the same time, the spring 35 is connected to the locking blocks 33 through the screw holes on the positioning blocks 36, which also facilitates the installation and removal of the spring 35. When the spring 35 is fatigued or damaged, the spring 35 can be replaced separately without replacing the entire component, which reduces maintenance costs and difficulty.

[0024] Please see Figures 1 to 4The upper end of the locking block 33 is provided with anti-slip textures 331 on both sides. When the air filter needs to be disassembled or maintained, the operator needs to push the locking block 33 by hand. The anti-slip textures 331 increase the friction between the fingers and the locking block 33, making it easier and more accurate for the operator to pinch the locking block 33 and apply pushing force, which facilitates the operation.

[0025] Please see Figures 1 to 4 The bottom protective box 2 is provided with a groove 24, and the bottom of the top sealing cover 3 is provided with a partition 38. The partition 38 can be completely inserted into the groove 24 provided on the bottom protective box 2. When the top sealing cover 3 is installed to the bottom protective box 2, the partition 38 inserted into the groove 24 can play a role in precise positioning, ensuring that the top sealing cover 3 and the bottom protective box 2 are accurately connected, so that the relative position between the two is fixed.

[0026] Please see Figures 1 to 4 The bottom protective box 2 has fixing blocks 21 welded to the four corners of the bottom. The fixing blocks 21 welded to the four corners of the bottom protective box 2 can be used to securely install the air filter fixing box 1 on the car.

[0027] During installation, the filter plate 5 is placed inside the bottom protective box 2. The fixing blocks 21 welded to the four corners of the bottom of the bottom protective box 2 are used to fix it to the corresponding installation position on the car, completing the initial positioning of the bottom protective box 2 on the car. Then, the positioning ring 31 of the top sealing cover 3 is aligned with the limiting ring 22 of the bottom protective box 2, so that the notch of the limiting ring 22 is aligned with the cavity 32 of the positioning ring 31. At this time, the partition 38 at the lower end of the top sealing cover 3 is inserted into the groove 24 provided on the bottom protective box 2, further playing a positioning and sealing role. At the same time, press the two ends of the locking block 33 to bring them together. When the abutment 34 at the lower end of the locking block 33 is flush with the limiting slot 23 of the limiting ring 22, then... After releasing the locking blocks 33 at both ends, the abutments 34 at both ends, through the elastic force of the springs 35, are inserted into the limiting slots 23, realizing the quick locking of the top sealing cover 3 and the bottom protective box 2, thus completing the installation of the fixed box 1. When it is necessary to replace the filter plate 5 or maintain the air filter, pinch the upper end of the locking block 33 with your hand, and use the anti-slip texture 331 to increase the friction, and push the locking block 33 to both sides. During the pushing process, the spring 35 is compressed, and the abutments 34 gradually disengage from the limiting slots 23. When the abutments 34 are completely disengaged from the limiting slots 23, the top sealing cover 3 and the bottom protective box 2 can be easily separated, completing the disassembly operation, which facilitates the inspection, replacement and maintenance of internal components such as the filter plate 5.

[0028] 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.
