Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted refrigerator equipment, in particular to a vehicle-mounted refrigerator door that is easy to assemble. Background Art

[0002] In the field of car refrigerators, the fixing method of the door assembly is crucial to the performance and appearance of the refrigerator. Currently, the fixing method of the door assembly of car refrigerators on the market mostly adopts the screw method, that is, the door outer shell and the door inner shell are fixed by a circle of screws under the door sealing strip, and the edge position can only be fixed by snap-on method because the screw holes cannot be hidden. However, this snap-on fixing method has obvious disadvantages. On the one hand, the tensioning force of the snap-on method is insufficient. When there is a covering on the edge of the door body, it is easy to cause the gap to be too large, affecting the overall aesthetics of the refrigerator. On the other hand, since the door sealing strip needs to be installed after the screws are driven into the door outer shell and the door inner shell, the installation process is more difficult, which increases the difficulty and cost of production and maintenance.

[0003] In summary, the existing method for fixing the door assembly of a vehicle-mounted refrigerator has many deficiencies and urgently needs improvement and innovation. Utility Model Content

[0004] The purpose of the utility model is to provide a vehicle-mounted refrigerator door that is easy to assemble, so as to solve the problems raised in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution, which includes a door body inner shell, a door body outer shell is arranged on the top of the door body inner shell, several plug-in columns are arranged at the bottom of the door body outer shell, a screw is arranged at the bottom of each plug-in column, and an anti-retreat serrated gasket is arranged between the screw and the plug-in column, and several mounting shells corresponding to the plug-in columns are arranged on the top of the door body inner shell, and the plug-in columns are inserted in the mounting shells.

[0006] As a preferred solution, the anti-retraction serrated gasket is in the shape of a disc with a concave center, and a circle of serrations is provided on the outer edge.

[0007] As a preferred solution, the serrations of the anti-retraction serrated gasket are clamped on the inner wall of the mounting shell.

[0008] As a preferred solution, a sealing ring is provided at the bottom of the inner shell of the door body.

[0009] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0010] 1. The utility model adopts a combination of plug-in columns, screws and anti-backward serrated gaskets to connect and fix the door outer shell and the door inner shell. Compared with the traditional snap-on fixing method, this connection method has stronger tensioning force, especially when the door outer shell is subjected to external pulling force, the serrations of the anti-backward serrated gasket will be stuck on the inner wall of the installation shell, playing the role of inverted fixing, effectively avoiding the problem of excessive gaps caused by insufficient tensioning force, and making the door appearance more beautiful.

[0011] 2. In the traditional method of fixing the door assembly of a car refrigerator, the door sealing strip needs to be installed after the screws are screwed into the door outer shell and the door inner shell. The installation process is relatively complicated. When installing this device, first put the anti-retraction serrated gasket on the screw, then fix the screw to the bottom of the plug post, and then align the plug post with the installation shell of the door inner shell and insert it. This installation method does not require complicated operations after installing the sealing strip, which greatly improves the installation efficiency and reduces the installation difficulty.

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0023] like Figures 1-9 As shown, the utility model proposes a car refrigerator door that is easy to assemble. The utility model includes a door inner shell 4, a sealing ring 41 is provided at the bottom of the door inner shell 4, which plays a sealing role, and a door outer shell 1 is provided on the top of the door inner shell 4. Several plug posts 10 are provided at the bottom of the door outer shell 1, and a screw 2 is provided at the bottom of each plug post 10. An anti-retreat serrated gasket 3 is provided between the screw 2 and the plug post 10. The anti-retreat serrated gasket 3 is a circular disc with a concave middle and a circle of serrations is provided on the outer side of the edge. Several mounting shells 40 corresponding to the plug posts 10 are provided on the top of the door inner shell 4, and the plug posts 10 can be inserted in the mounting shell 40. At this time, the anti-retreat serrated gasket 3 is stuck on the inner wall of the mounting shell 40 to prevent the plug posts 10 from withdrawing. This connection structure is cleverly designed to ensure that the connection between the door outer shell 1 and the door inner shell 4 is firm and reliable.

[0024] When in use, first put several anti-retreat serrated gaskets 3 on several screws 2 in turn, then fix these screws 2 to the bottom of several plug posts 10 respectively, and then align the bottom of several plug posts 10 with several mounting shells 40 in the inner shell 4 of the door body and slowly insert them. During the insertion process, when the anti-retreat serrated gasket 3 is pressed down, its serrations will be subjected to the force of the top edge of the mounting shell 40, thereby being deformed and squeezed inward. In this way, the anti-retreat serrated gasket 3 can be smoothly inserted into the mounting shell 40. When the door body outer shell 1 is subjected to external pulling force, the serrations of the anti-retreat serrated gasket 3 will be tightly stuck on the inner wall of the mounting shell 40, playing the role of inverted fixing. At this point, the assembly of the car refrigerator door body is completed and can be put into normal use. This assembly method is easy to operate and can ensure that the door body remains firm and stable during use.

[0025] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents of such scope and metes and bounds.
