Technical Field

[0001] The utility model relates to the technical field of freezer height adjustment, in particular to a freezer height adjustment mechanism. Background Art

[0002] A freezer, also known as a refrigerator or a freezer cabinet, is a device used to store and display refrigerated food and beverages, aiming to maintain the freshness and taste of these items. When installing a freezer, since the ground may be uneven, it is necessary to adjust the height of the feet of the freezer so that the freezer can be placed stably on the ground.

[0003] Currently, the common height adjustment mechanisms on the market are to first open an opening on a square tube plug, then weld a nut to the square tube plug, and then weld the welded square tube plug to the square tube. Subsequently, a bolt is screwed to the nut on the square tube plug.

[0004] This adjustment mechanism has cumbersome processing steps, many processes, and takes a long time. Since welding is required during the processing, it has high technical requirements for workers and there are also certain safety hazards.

[0005] Therefore, this application provides a freezer height adjustment mechanism to overcome the defects of the prior art. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the problems of the existing adjustment mechanism with cumbersome processing steps, many processes, long time consumption, high technical requirements for workers, and safety hazards.

A light hole is formed inside the four arc plates.

[0009] The inner diameter of the light hole is the same as the minor diameter of the bolt, and the diameter of the internal thread hole is 16 mm.

[0010] The surface roughness of the nylon tube plug is not greater than Ra6.3, and the load-bearing capacity of the nylon tube plug is not less than 0.6 tons.

[0011] The beneficial effects of the present utility model are as follows: A height adjustment mechanism for a freezer provided by the present utility model enables the device to be quickly installed by simply inserting a nylon tube plug into a square tube and then screwing a bolt onto the nylon tube plug through the provision of a bolt and a nylon tube plug connected by a bolt. The installation process is simple, takes a short time, does not require welding, has low requirements for workers' skills, and eliminates potential safety hazards.

[0023] In order to make the technical means, technical features, utility model purpose and technical effects achieved by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative work shall fall within the protection scope of the present utility model.

[0024] Prior art

[0025] As Figure 1 、 Figure 2 shown: A common height adjustment mechanism on the market is given. This adjustment mechanism utilizes selecting a plug of appropriate size, opening a hole of a certain size in the plug, welding a nut on the plug, then welding the plug on a square tube, and then screwing a bolt with the nut. By rotating the bolt, the use height of the bolt is adjusted, so that the freezer can be stably placed on the ground.

[0026] This adjustment method can indeed adjust the height so that the freezer can be stably placed on the ground. However, since this adjustment mechanism requires multiple weldings, the technical requirements for workers are relatively high. The welding level of the workers also affects the service life of the components. At the same time, there are also certain safety hazards, and the process is more, and the time consumed is also longer. Embodiment

[0027] In order to solve the problems of the existing adjustment mechanism, through a large number of experiments, we have developed a new adjustment mechanism to overcome some defects of the original equipment. The specific situation is as follows:

[0028] As shown in the appended Figure 3 to the appended Figure 9 shown: A freezer height adjustment mechanism includes a nylon tube plug 7, a bolt 8 is screwed in the nylon tube plug 7, and the nylon tube plug 7 is inserted into a square tube.

[0029] As shown in the appended Figure 4 to the appended Figure 8As shown in the figure: The nylon pipe plug 7 includes a clamping plate 1 with a thickness of 3.5 mm. A base 2 is fixed on the top of the clamping plate 1 with a height of 9 mm, and both the length and width are 35.7 ± 0.3 mm (the four corners are chamfered). An internal threaded hole 3 is provided at the center of the clamping plate 1 and the base 2, and the diameter of the internal threaded hole 3 is 16 mm. A plug-in part is fixed on the top of the base 2 with a height of 14.5 mm. The plug-in part includes four vertical plates 4. The tops of the vertical plates 4 incline towards the side close to the internal threaded hole 3 to facilitate inserting the pipe plug into the square pipe. A curved plate 5 is connected to the side of each vertical plate 4 close to the internal threaded hole 3. An optical hole 6 is formed inside the four curved plates 5. The diameter of the optical hole 6 is the same as the minor diameter of the bolt 8. After the bolt 8 is installed, it can squeeze the curved plate 5 towards the square pipe wall, effectively preventing the pipe plug from falling off.

[0030] The length and width of the top view of the plug-in part are both 34.5 mm, and its four corners are chamfered, which can be regarded as a square with chamfered corners for better insertion into the square pipe. The chamfer radius is 3 mm. The length of the top of the plug-in part is first subtracted by the diameter of the optical hole 6, and then added with the diameter of the bolt 8. The final result is greater than the length of the base 2. The advantage of doing this is that after the bolt 8 is inserted into the optical hole 6, it will squeeze the vertical plate 4 and the curved plate 5, preventing the nylon pipe plug 7 from detaching from the square pipe.

[0031] The surface roughness of the nylon pipe plug 7 is not greater than Ra6.3. When the load-bearing of a single nylon pipe plug 7 is 0.6 tons, there will be no thread stripping phenomenon for the nylon pipe plug 7. After the pipe plug is installed with the bolt, when a heavy hammer drops and impacts the bolt at a specified height, there should be no problems such as thread stripping or pipe plug damage that affect normal use.

[0032] Working method: Insert the nylon pipe plug 7 into the square pipe until the bottom wall of the square pipe abuts against the top wall of the clamping plate 1. Install the bolt 8 into the internal threaded hole 3 and adjust the length of the bolt 8 in the nylon pipe plug 7 according to specific conditions. When the bolt 8 enters the optical hole 6, it will squeeze the curved plate 5 and the vertical plate 4 towards the square pipe wall, preventing the nylon pipe plug 7 from falling off.

[0033] In summary, the above is only a preferred embodiment of the present invention and is not used to limit the implementation scope of the present invention. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present invention should fall within the technical scope of the present invention.
