Description

Technical Field

[0001] This utility model relates to a sealing mechanism for the door of a low-temperature refrigerator, belonging to the technical field of sealing mechanisms. Background Technology

[0002] A freezer is another name for a refrigerated display case. High-quality freezers use premium copper coils for all evaporator tubes, shaped into wide, irregular sections. The stainless steel plates have a smooth surface and uniform thickness, ensuring a long service life and a sturdy, flat appearance. Copper tubes offer better heat transfer and corrosion resistance than aluminum or composite tubes. High-quality copper coils have the advantages of high internal cleanliness and fewer joints, effectively preventing leaks or blockages in the refrigeration system. Transforming round tubes into rectangles changes the contact between the evaporator tubes and the inner liner from point contact to surface contact, increasing the heat transfer area and accelerating cooling.

[0003] Chinese Patent Publication No. CN 209840509 U discloses a sealing mechanism for a low-temperature refrigerator door, relating to the field of refrigerators. The mechanism includes a cabinet body and a door. The door is rotatably connected to one side of the cabinet body via a pivot. A first sealing strip and two fixing blocks are fixed to the inner side of one end of the door. The two fixing blocks are located on the upper and lower sides of the first sealing strip, respectively. In this invention, by providing a first and second sealing strip, fixing blocks, and fixing grooves at the connection point between the cabinet body and the door, and by providing protruding blocks and recessed grooves on the first and second sealing strips, the mechanism achieves a wider contact area and better sealing performance. Furthermore, the engagement of the fixing blocks with the fixing grooves enhances stability.

[0004] The aforementioned device only seals the left side of the refrigerator door, while the top, bottom, and left sides may experience cold air leakage. Furthermore, the device primarily relies on elastic blocks to secure the door, but these blocks are typically made of rubber and other materials. Over time, these blocks may age and deform, potentially preventing them from securing the door properly. This could lead to the sealing strips failing to adhere properly, resulting in cold air leakage from the refrigerator.

[0005] To address this, a sealing mechanism for the door of a low-temperature refrigerator is proposed. Utility Model Content

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-6As shown, this utility model embodiment provides a low-temperature refrigerator door sealing mechanism, including a refrigerator cabinet 1, a cabinet door 3 movably connected to the front side of the refrigerator cabinet 1, a handle 4 fixedly installed on the front side of the cabinet door 3, and a sealing component 2 provided on the surface of the refrigerator cabinet 1 and the cabinet door 3. The sealing component 2 includes a box body 201, and a box body 201 is provided on both the upper and lower sides of the refrigerator cabinet 1. Four rigid springs 202 are fixedly connected to the outer sides of the inner cavities of the four box bodies 201. The other end of each of the four movable blocks 203 is fixedly connected to a movable block 203. An installation rod 204 is fixedly installed on the inner side of each of the four movable blocks 203. A limit block 205 is fixedly installed on the inner side of each of the four installation rods 204. Connecting rods 206 are fixedly installed on the upper and lower sides of the cabinet door 3. A limit block 207 is fixedly installed on the other end of each of the two connecting rods 206. A first sealing strip 208 is fixedly installed on the rear side of the cabinet door 3. A second sealing strip 209 is fixedly installed on the front side of the refrigerated cabinet 1. The four limit blocks 205... The inner sides of the four limiting blocks 205 are all at a 45-degree angle. The front and rear sides of the two limiting blocks 207 are also at a 45-degree angle. The surfaces of the two limiting blocks 207 are all in contact with the surfaces of the four limiting blocks 205. The first sealing strip 208 is convex in shape, and the second sealing strip 209 is concave in shape. The front and rear sides of the four boxes 201 are all provided with sliding grooves 210. The front and rear sides of the four moving blocks 203 are all slidably connected to the inner cavities of the eight sliding grooves 210. The inner sides of the surfaces of the four boxes 201 are all provided with sliding grooves 210. The refrigerator is provided with slots 211. Four mounting rods 204 pass through the inner cavity of the four slots 211 and extend to the inner side of the four boxes 201. The outer side and rear side of the four boxes 201 are threaded with first mounting bolts 212. The inner side of the eight first mounting bolts 212 is threaded to the inner surface of the refrigerator cabinet 1. The left and right sides of the two connecting rods 206 are threaded with second mounting bolts 213. The inner side of the four second mounting bolts 213 is threaded to the inner surface of the cabinet door 3.

[0031] By setting the sealing component 2, under the influence of the tension of the rigid spring 202, the limiting block 205 can be engaged with the position of the limiting block 207. This ensures that the first sealing strip 208 and the second sealing strip 209 are stably fitted together when the cabinet door 3 is closed, without affecting the opening and closing of the cabinet door 3. Furthermore, the second sealing strip 209 and the first sealing strip 208 are set around the front side of the refrigerated cabinet 1 and the rear side of the cabinet door 3, effectively sealing the area where the cabinet door 3 and the refrigerated cabinet 1 are fitted together. This effectively prevents cold air leakage and improves the stability of the refrigerated cabinet 1 during operation. For ease of use by operators, the sliding groove 210 can limit the movement of the moving block 203, preventing it from shifting and affecting the limiting operation of the cabinet door 3. The slot 211 can limit the movement of the mounting rod 204, preventing the mounting rod 204 from changing direction and affecting the limiting operation of the cabinet door 3. The first mounting bolt 212 and the second mounting bolt 213 can facilitate the disassembly and assembly of the box body 201 and the connecting rod 206, making it convenient to repair and replace the parts connected to the box body 201 and the connecting rod 206.

[0032] Example 2

[0033] In one embodiment, a temperature sensor 5 is fixedly installed on the top of the inner cavity of the refrigerator cabinet 1, a temperature display panel 6 is fixedly installed on the left side of the refrigerator cabinet 1, and U-shaped plates 7 are movably connected to the left and right sides of the bottom of the refrigerator cabinet 1, with movable wheels 8 movably connected to the inner sides of the four U-shaped plates 7.

[0034] By setting temperature sensor 5 and temperature display panel 6, the temperature inside the refrigerator cabinet 1 can be easily detected and displayed, making it convenient for users to understand the temperature inside the refrigerator cabinet 1. By setting U-shaped plate 7 and casters 8, the refrigerator cabinet 1 can be easily moved, making it easy to push and pull according to usage needs.

[0035] In operation, when the cabinet door 3 is closed, the connecting rod 206 drives the limiting block 207 to insert into the inner side of the two limiting blocks 205. Due to the shape characteristics of the limiting blocks 205 and 207, the limiting block 207 can push the limiting block 205 to move outward. At this time, the limiting block 205 simultaneously drives the mounting rod 204 and the moving block 203 to move outward. The rigid spring 202 deforms due to the compression of the moving block 203 during movement, and then releases the limiting block 207. When the device moves to the rear of the limiting block 205, the rigid spring 202 loses the effect of the compressive force and deforms again. It then pushes the moving block 203 to move inward through its own tension. This causes the mounting rod 204 and the limiting block 205 to move inward synchronously and limit the position of the limiting block 207. At the same time, since the refrigerator cabinet 1 and the cabinet door 3 are in contact with each other, the first sealing strip 208 is engaged with the second sealing strip 209, thereby completing the sealing work of the refrigerator cabinet 1 and the cabinet door 3.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
