[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] like Figure 1-Figure 2 As shown, the present application provides an instrument fastener, including an instrument panel 1, which is arranged in the vehicle and is used to provide the driver with various information about the vehicle. At the same time, a cover assembly 2 is arranged on the instrument panel 1, and the cover assembly 2 is used to cover the instrument panel 1, which helps to improve the driver's browsing experience of the vehicle information and protect the life of the instrument panel 1.

[0024] The housing assembly 2 includes a dustproof frame 21, which is made of a transparent material and is used to prevent dust or impurities from entering the interior of the instrument panel 1. At the same time, a mounting cavity 3 is provided on the inner side of the instrument panel 1, and the size of the dustproof frame 21 is adapted to the size of the mounting cavity 3.

[0025] The bottom and top of the inner side of the installation cavity 3 are both provided with guide blocks 31, and a plurality of slide grooves 211 are provided on the dustproof frame 21 corresponding to the positions of the guide blocks 31. The slide grooves 211 are adapted to the sizes of the guide blocks 31, and the slide grooves 211 and the guide blocks 31 are used to guide the dustproof frame 21 into the installation cavity 3.

[0026] At the same time, a bottom plate 22 is arranged on one side of the dustproof frame 21. When the cover shell assembly 2 is placed in the installation cavity 3, the bottom of the bottom plate 22 contacts the bottom of the installation cavity 3. At the same time, multiple groups of springs 23 are arranged between the dustproof frame 21 and the bottom plate 22. One end of the spring 23 is fixed on the dustproof frame 21, and the other end is fixedly installed on the bottom plate 22.

[0027] like Figure 3 As shown, a connecting assembly 4 is provided between the dustproof frame 21 and the mounting cavity 3, and the connecting assembly 4 includes two groups of ratchet plates 41, and the two groups of ratchet plates 41 are respectively provided on both sides of the dustproof frame 21, and a mounting groove 42 is provided at the side of the mounting cavity 3 corresponding to the position of the dustproof frame 21, and a ratchet 43 is provided inside the mounting groove 42, and the ratchet 43 is rotatably connected to the inside of the mounting groove 42 through a rotating shaft, and a torsion spring is provided inside the ratchet 43, and the torsion spring is used to restore the ratchet 43 to the initial position;

[0028] The size of the pawl 43 is adapted to that of the ratchet plate 41. When the dustproof frame 21 is installed in the installation cavity 3, the bottom plate 22 contacts the bottom of the installation cavity 3. As the dustproof frame 21 gradually goes deeper, the spring 23 is squeezed by the dustproof frame 21 and elastically deforms, and its reaction force is applied to the dustproof frame 21, so that the dustproof frame 21 moves in a direction away from the installation cavity 3. At this time, the pawl 43 and the ratchet plate 41 are meshed with each other, so that the pop-up of the dustproof frame 21 is blocked by the pawl 43, and the dustproof frame 21 is firmly fixed in the installation cavity 3, thereby completing the installation of the dustproof frame 21.

[0029] When the dustproof frame 21 needs to be removed from the installation cavity 3, the rear end of the pawl 43 is pressed so that the pawl 43 tilts upward. At this time, the pawl 43 can be disengaged from the ratchet plate 41, and the dustproof frame 21 pops out of the installation cavity 3 under the action of the spring 23. At this time, the dustproof frame 21 can be quickly taken out to achieve rapid disassembly of the cover shell assembly 2.

[0030] In summary, the device makes it easier to load and unload the dustproof frame 21 and the mounting cavity 3 by providing a cover assembly 2 that can be quickly loaded and unloaded, which facilitates the loading and unloading of the instrument panel 1 by the staff, helps to save time and improve the convenience of operation, provides a better solution for the maintenance and care of the instrument panel 1, and increases the practicality of the device.

[0031] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
