[0002] A vehicle-mounted refrigerator is a portable device that provides food and beverage refrigeration functions during vehicle driving, and it is very popular in occasions such as long-distance travel, outdoor activities, and camping. The design of a vehicle-mounted refrigerator not only needs to consider the refrigeration performance, but also needs to ensure the safe storage of food and beverages during driving. This requires the vehicle-mounted refrigerator to have a reliable door latch mechanism to prevent the refrigerator door from accidentally opening during vehicle bumps and turns.

[0003] The existing installation methods of vehicle-mounted refrigerator door latches are usually pin spring type and pin torsion spring type. However, after long-term use, the pins and door latches will become loose, and the door latch is very easy to directly fall off when the force is too large. This solution provides a structural installation solution for a vehicle-mounted refrigerator door latch structure with convenient installation, improving the durability of the door latch and the force-bearing strength of the door latch.

A door latch housing is arranged on the outer side of the connecting piece. One end of the door latch housing is connected with several buckles. The door latch housing and the connecting piece are rotationally connected through two groups of quick-installation connecting shaft structures symmetrically installed. An elastic component is arranged between the front side of the connecting piece and the door latch housing; the quick-installation connecting shaft structure includes a spring adjusting shaft structure arranged on the connecting piece and a door shaft guiding and limiting installation structure arranged in the door latch housing.

[0006] Preferably, the spring adjusting shaft structure includes a driving part connected to the front end of the bottom of the connecting piece. A hole is opened towards the inner side of the driving part. A door shaft slides in the hole. A door shaft spring is connected between the tail of the door shaft and the root of the hole in the driving part.

[0007] Preferably, the door shaft guiding and limiting installation structure includes a guiding chute arranged in the door latch housing. The front end of the door shaft is movably arranged in the guiding chute. A door shaft hole is opened at the front end position of the guiding chute, and the inner shape of the door shaft hole is the same as that of the hole in the driving part.

[0008] Preferably, several limiting ribs are arranged inside one end of the door shaft hole far from the driving part.

[0009] Preferably, the elastic component includes several first spring seats arranged in the connecting piece, several second spring seats opposite to the first spring seats are arranged in the door buckle housing, and a door buckle spring is arranged between each group of opposite first spring seats and second spring seats.

[0010] After adopting the above structure, the beneficial effects of the present utility model are as follows:

[0011] In this device, the door shaft is elastically arranged in the door shaft hole by means of the door shaft spring, there is no weak point in the side of the door shaft, and the door shaft will not fall off due to force during use, with a long service life and good stability.

[0012] This device can be installed directly by pushing the door buckle housing, and the installation is simple and efficient.

[0013] This device can be disassembled by inserting a tool into the door shaft hole, which is convenient for later maintenance. Description of the Drawings

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Refer to Figures 1 - 8 As shown, it includes a connecting member 4 installed on the refrigerator door 1. A door buckle housing 2 is arranged on the outer side of the connecting member 4. One end of the door buckle housing 2 is connected with several buckles 3. The door buckle housing 2 and the connecting member 4 are rotationally connected through two groups of quick-installation connecting shaft structures symmetrically installed. An elastic component is arranged between the front side of the connecting member 4 and the door buckle housing 2; the quick-installation connecting shaft structure includes a spring adjustment shaft structure arranged on the connecting member 4 and a door shaft guiding and limiting installation structure arranged in the door buckle housing 2;

[0026] The spring adjustment shaft structure includes a driving part 8 connected to the front end of the bottom of the connecting member 4. A hole is opened towards the inner side of the driving part 8. A door shaft 10 slides in the hole. A door shaft spring 9 is connected between the tail of the door shaft 10 and the root of the hole in the driving part 8;

[0027] The door shaft guiding and limiting installation structure includes a guiding chute 13 arranged in the door buckle housing 2. The front end of the door shaft 10 is movably arranged in the guiding chute 13. A door shaft hole 11 is opened at the front end position of the guiding chute 13. The inner shape of the door shaft hole 11 is the same as that of the hole in the driving part 8;

[0028] A number of limiting ribs 12 are arranged at one end of the door shaft hole 11 away from the driving part 8;

[0029] The elastic component includes several first spring seats 5 arranged in the connecting member 4. Several second spring seats 6 opposite to the first spring seats 5 are arranged in the door buckle housing 2. A door buckle spring 7 is arranged between each group of opposite first spring seats 5 and second spring seats 6.

[0030] The principle and usage process of the present invention:

[0031] First, install the connecting member 4 on the refrigerator door 1, and then as Figure 2Place the door buckle housing 2 as shown, so that the door shaft 10 enters the guiding chute 13. At the same time, place several door buckle springs 7 between the first spring seat 5 and the second spring seat 6 respectively. Then, push the connecting member 4 and the door buckle housing 2 relative to each other, so that the door shafts 10 on both sides slide along the guiding chute 13. At the same time, the door shaft springs 9 gradually contract. When the door shaft 10 is opposite to the door shaft hole 11, the door shaft spring 9 pops out the door shaft 10, and the door shaft 10 enters the door shaft hole 11, that is, the connection between the door buckle housing 2 and the connecting member 4 is completed. At this time, the door buckle housing 2 and the connecting member 4 can rotate through the door shaft 10, and the limiting rib 12 prevents the door shaft 10 from popping out to the other side from the door shaft hole 11. When the door buckle housing 2 is pressed, the door buckle spring 7 will be compressed accordingly. After releasing the hand, the door buckle spring 7 can push the door buckle housing 2 back;

[0032] When disassembly and maintenance are required, just insert a tool from the opening on the side of the door shaft hole 11 away from the driving part 8, push the door shaft 10 back, so that the door shaft 10 returns to the driving part 8, so that the door buckle loses the connection locking force, and the door buckle housing 2 and the connecting member 4 can be separated.

[0033] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope 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 boundary of the appended claims, or equivalent forms of such scope and boundary.
