Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to the field of freezer power cord storage technology, specifically a hinge for storing power cords in freezers. Background Technology

[0002] There are two main types of power cord exit methods for freezers: side exit and rear exit. Side exit means the cord exits from the compressor cover, while rear exit means it exits from the protective cover behind the compressor. Both methods require the power cord to be installed before installing the cover or cover. According to freezer power cord installation specifications, the length of the power cord is usually greater than 1.5 meters. During production, after the power cord is installed, it needs to be coiled up for safekeeping to prevent it from getting caught in the production line, causing damage, or the freezer falling off the line due to entanglement. Since freezers and other refrigeration equipment require frequent power-on checks via the power cord during production, such as electrical checks, high and low pressure leak checks, and temperature checks, the power cord needs to be removed or coiled up for safekeeping before and after each check. This is cumbersome, time-consuming, and labor-intensive, severely impacting work and production efficiency. Furthermore, to protect the power cord plug from damage, when coiling up the power cord for safekeeping, the plug must be placed inside the freezer. The cabinet body of a freezer is usually lined with corrosion-resistant aluminum or steel plates. During the production process, the inner surface of the cabinet body may be damaged due to collisions between the plug and the cabinet body, which will affect the appearance and quality of the cabinet body lining.

[0003] Therefore, there is a need for a storage structure that can prevent power cords from getting tangled in the production line and causing damage to the power cords or refrigerators, while also allowing for quick and convenient storage and retrieval of the power cords. Utility Model Content

[0004] The main purpose of this utility model is to provide a hinge for storing power cords in freezers, so as to solve the problem that storing and retrieving power cords in freezers during the production process is not simple and quick in the existing technology.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1 to 9The hinge shown is for storing power cords in a freezer. It includes a hinge base 11 and a hinge head 12. The hinge head 12 is hinged to the hinge base 11 via a hinge shaft 13. When the freezer lid is opened or closed, the hinge head 12 can rotate relative to the hinge base 11 along the hinge shaft 13. Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the bottom of the hinge base 11 is provided with a hook 41 for storing the power cord, and the bottom of the hinge head 12 is provided with a movable shaft 21, as shown. Figure 2 and Figure 5 As shown, a vertical support rod 31 is positioned at the central axis of the hinge seat 11. The top of the support rod 31 is mounted on the movable shaft 21, and a hinge spring 32 is sleeved on the lower middle part of the support rod 31. The hinge head 12, hinge seat 11, and hook 41 are all made of metal, preferably galvanized steel. Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the hook 41 and the hinge seat 11 are integrally formed, as... Figure 7 , Figure 8 and Figure 9 As shown, a bending groove 42 for folding the hook 41 is provided at the connection between the hook 41 and the hinge seat 11. Both the left and right sides of the hinge seat 11 are provided with wall plates, forming a seat groove between the two wall plates. The opening direction of the bending groove 42 is consistent with the opening direction of the seat groove, as shown. Figure 2 , Figure 3 and Figure 4 As shown, the fully bent hook 41 is located within the seat groove. By providing a bending groove 42 at the connection between the hook 41 and the hinge seat 11, it is convenient to bend the hook 41 and hide it within the seat groove of the hinge seat 11 during hinge cover installation, thus preventing the hook 41 from interfering with the installation of the hinge cover. Figure 5 and Figure 6 As shown, the width b of the hook 41 is 6 mm. The width b of the hook 41 and the thickness of the metal plate at the bending groove 42 affect the strength and load-bearing capacity of the hook 41, as well as the ease of folding the hook 41. Therefore, when setting the hook 41, it is necessary to ensure that the hook 41 can bear the power cord, and also ensure that the hook 41 can be bent smoothly and hidden in the seat groove, ensuring smooth installation of the hinge cover. At the same time, the hook 41 has an appropriate width b, which can reduce or avoid wear on the suspended power cord caused by the hook 41.

[0021] This hinge structure is suitable for freezers that open from top to bottom. The hinge is located at the connection between the rear cover and the cabinet body. The hinge seat 11 is located on the cabinet body, and the hinge head 12 is located on the cover. By setting a hook 41 for storing the power cord on the hinge near the power cord, the power cord is suspended from the freezer body using the hook 41 at the bottom of the hinge seat 11. This allows for the storage of the power cord during the freezer production process, keeping it away from the rolling equipment on the production line to avoid damage to the freezer body and the power cord. It also allows for simple and quick retrieval and storage of the power cord during electrical testing of the freezer, improving production efficiency. After the freezer is finished and enters the packaging process, to prevent the hook 41 from interfering with the installation of the hinge cover, the hook 41 can be bent along the bending groove 42 and folded into the seat groove formed by the two side panels of the hinge seat 11. When the external hinge cover is engaged with the hinge seat 11, the hook 41 is hidden.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, a support plate 33 is provided at the top of the hinge spring 32, and the support plate 33 is sleeved on the support rod 31; a support seat 34 is provided at the bottom of the hinge spring 32, and the support seat 34 is set on the hinge seat 11. A protective pad is provided between the support seat 34 and the hinge spring 32. The support seat 34 is fixedly set on the hinge seat 11, and the support plate 33 is set on the support rod 31 and fixedly connected to the support rod 33. The hinge spring 32 is compressed by the support plate 33 and the support seat 34, providing support force for the opening and closing of the cabinet lid. The protective pad can prevent the spring from shifting position during compression and extension. The protective pad is made of nylon material, which can reduce the noise when the spring is working. The hinge spring 32 has a total of 7 turns, with 1 turn at the end, and rotates clockwise. Always in a compressed state, the compressed hinge spring 32 exerts an upward force on the support plate 33, which can provide a certain support for opening the cabinet lid, so that the cabinet lid can maintain a certain opening and closing angle.

[0023] Specifically, such as Figure 4 and Figure 8 As shown, both the support base 34 and the protective pad have through holes in their middle sections. The lower end of the support rod 31 extends into the through hole and can move up and down within it. When the cabinet cover is fully closed, the movable shaft 21 is located at the bottom of the guide groove 22, and the support rod 31 is in an inclined state. As the cabinet cover is opened, the movable shaft 21 moves along the guide groove 22, and the top of the support rod 31 moves upward as the arc plate rotates. The support rod 31 gradually becomes vertical and / or moves upward within the through hole. Conversely, as the cabinet cover is closed, the support rod 31 gradually becomes inclined and / or moves downward within the through hole.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, an arc-shaped transition plate 24 is sleeved on the movable shaft 21, and the arc-shaped transition plate 24 is rotatably connected to the movable shaft 21. The top of the support rod 31 is connected to the arc-shaped transition plate 24. During the opening and closing of the cabinet cover, the movable shaft 21 rotates along the guide groove 22. By sleeved with the rotatable arc-shaped transition plate 24 on the movable shaft 21, it can be ensured that the top of the support plate 33 can rotate relative to the movable shaft 21 with the arc-shaped transition plate 24 during the opening and closing of the cabinet cover.

[0025] Specifically, such as Figure 3 and Figure 7 As shown, an arc-shaped guide groove 22 is provided on the hinge seat 11 corresponding to the position of the movable shaft 21. The hinge seat 11 is located on the back of the cabinet, and the hinge head 12 is located on the cabinet cover corresponding to the position of the hinge seat 11. When the cabinet cover is closed, the hinge head is in a vertical state, and the movable shaft 21 is located at the bottom of the guide groove 22. As the cabinet cover is opened, the hinge head rotates along the hinge shaft 13 and gradually tends to a horizontal state. The hinge shaft 13 moves backward and upward along the guide groove 22, thereby driving the support rod 31 to move.

[0026] Specifically, such as Figure 2 and Figure 5 As shown, bushings 23 are provided at both ends of the movable shaft 21 and the hinge shaft 13. Lubricant is applied between the shaft and the bushings 23 to reduce friction, decrease noise, and increase the service life of the parts. Lubricants include lubricating oil and environmentally friendly grease.
