Description

A hinge device applied to a freezer

technical field

The utility model relates to a hinge device applied to a freezer.

Background technique

At present, in the existing technology, the installation hinges of refrigerators are mostly purchased directly from the manufacturer. The main basis for selection is the size and weight of the door body. At present, most hinges for refrigerators are distinguished by the size of the hinge body and the thickness of the spring. Most of the selected matching hinges meet the basic usage principle that the door body can be stopped at a fixed angle. However, with the increasing number of small cabinet glass doors and single-door large cabinet products, most of the existing hinges can only stop the door at a large angle, but because the door is heavy, the user will still feel that the door is heavy at the moment of opening.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a hinge device applied to a freezer to solve the problem that the door of the freezer is heavy and difficult to open.

The utility model is achieved through the following technical solutions:

A hinge device applied to a freezer, comprising an upper hinge body and a lower hinge body, the upper hinge body is fixedly installed on the door body of the freezer, the lower hinge body is fixedly installed on the box body of the freezer, and the upper hinge body The hinge body and the lower hinge body are rotatably connected, the hinge device also includes a support rod, the lower end of the support rod is connected with the lower hinge body through a support rod seat, and a perforation is arranged on the support rod seat, and the lower end of the support rod penetrates downward Through the perforation of the support rod seat, a spring is set on the support rod, the upper and lower ends of the spring are respectively limited by the limit steps on the support rod and the support rod seat, and the upper hinge body is fixed with a The rotating shaft is fitted with a shaft sleeve, the top of the support rod is provided with an arc-shaped groove matching the shaft sleeve, the bottom wall of the arc-shaped groove of the support rod is provided with a protrusion, and the shaft The sleeve is provided with a groove fitted with the protrusion.

Both sides of the top of the lower hinge body are provided with upwardly protruding hanging plates, the hanging plates are provided with hanging holes, the upper hinge body is provided with positioning pins, and the lower hinge body is hung on the upper hinge body through the hanging plates. on the positioning pin of the hinge body.

Compared with the prior art, the utility model has the following advantages:

The utility model provides a hinge device applied to freezers. Under the elastic force of the spring, when the door is opened, the spring will push the support rod to move upward, and the protrusion in the arc-shaped groove at the upper end of the support rod will push the shaft sleeve to rotate. Then, the rotating shaft is driven to rotate to provide assistance for opening the door, which solves the problem that the door body of the freezer is difficult to open due to its heavy weight, and enables the door body to be opened easily. In addition, the utility model has the advantages of simple structure, convenient installation and disassembly, and convenient after-sales maintenance.

detailed description

The following is a detailed description of the embodiments of the present utility model. This embodiment is implemented on the premise of the technical solution of the present utility model, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present utility model is not limited to the following the described embodiment.

Referring to Fig. 1 and Fig. 2, this embodiment discloses a hinge device applied to a freezer, including an upper hinge body 1 and a lower hinge body 2, the upper hinge body 1 is fixedly installed on the door body of the freezer, and the lower hinge body 2 is fixed Installed on the box body of the freezer, the upper hinge body 1 and the lower hinge body 2 are rotatably connected, and the two sides of the top of the lower hinge body 2 are provided with hanging plates 21 protruding upwards. The hanging plates 21 are provided with hanging holes. The upper hinge body 1 A positioning pin 3 is arranged on the top, and the lower hinge body 2 is hung on the positioning pin 3 of the upper hinge body 1 through a hanging plate 21 .

Hinge device also comprises support bar 4, and support bar 4 lower ends are connected with lower hinge body 2 by support bar seat 5, and support bar seat 5 is provided with perforation, and support bar 4 lower ends pass through the perforation of support bar seat 5 downwards, and support bar 4. A spring 6 is set on the top. The upper and lower ends of the spring 6 are respectively limited by the limit step 41 on the support rod 4 and the support rod seat 5. The upper hinge body 1 is fixed with a rotating shaft 7, and the rotating shaft 7 is covered with a shaft sleeve. 8. The top of the support rod 4 is provided with an arc-shaped groove matching the shaft sleeve 8, the bottom wall of the arc-shaped groove of the support rod 4 is provided with a bump 42, and the shaft sleeve 8 is provided with a groove that fits with the bump 42. groove.

The spring 6 on the support rod 4 is in a compressed state when the door is closed. When the user opens the door, under the elastic force of the spring 6, the spring 6 will push the support rod 4 to move upward, and the protrusion 42 in the arc-shaped groove at the upper end of the support rod 4 will drive the shaft sleeve 8 to rotate, and then drive the rotating shaft 7 to rotate , to provide assistance for the user to open the door, so that the user can easily open the door, which solves the problem that the freezer door is difficult to open due to its heavy weight.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model should be included in the utility model. within the scope of protection.
