Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a novel refrigerator door frame structure. Background Art

[0002] A freezer, also known as a freezer, is a device that preserves food and other items at low temperatures. There are two types of freezers: home and commercial. Commercial freezers are used in restaurants, bars, food processing facilities, and supermarkets. A freezer structurally consists of a refrigerator, a refrigeration system, and an electrical system. Its primary function is to keep the interior of the freezer cool, maintaining a suitable low temperature. A refrigeration system generally consists of four basic components: a compressor, a condenser, a capillary tube or thermal expansion valve, and an evaporator. A common example of a freezer is the glass-door sliding freezer commonly found in supermarkets.

[0003] However, when the current glass-door sliding freezers are pushed to the sides to close the door, customers often cannot control the force used to close the door well, causing the door to rebound when it hits the door frame, resulting in a gap and additional increase in power consumption. At the same time, when a collision occurs, the reaction force is transmitted to the glass, which may cause the glass to break. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] When the handle of the utility model pushes the cabinet door along the slide to one side of the door frame, the lock block is inserted into the square hole, and then the arc surface of the lock block presses against one end of the hook-shaped part of the rotating block, so that the rotating block rotates counterclockwise by a certain angle based on the pin shaft. At this time, the spring on the left side is deformed and compressed, and the lock block squeezes the support rod to make the spring at its bottom deformed and compressed, and at the same time plays a buffering role. When the hook-shaped part moves to the lock hole along the lock block, the movable block rotates clockwise under the action of the left spring to insert the hook-shaped part into the lock hole, thereby locking the cabinet door there, preventing the cabinet door from rebounding when it is closed and increasing power consumption. The support rod and the spring cooperate to play a buffering role, avoiding glass breakage to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The cabinet door 2 is arranged in the door frame 3 , and the edge of the cabinet door 2 is slidably installed in the slideway 31 .

[0023] The cabinet door 2 and door frame 3 in this case are refrigerators with sliding glass doors in daily life. The cabinet door 2 itself can slide on the slide 31 on the inner wall of the door frame 3, so it is not described in detail. At the same time, when the cabinet door 2 is closed, one end of the cabinet door 2 can be moved into the inside of the slide 31, and then the locking block 32 can be moved into the square hole 61.

[0024] Slide plate 51 is larger than groove 5 and slidably mounted on groove 5, which is located directly above hollow section 6. The groove 5 and hollow section 6 are interconnected, and a lever 52 on the underside of slide plate 51 passes through the groove 5 and hollow section 6 to connect to right-angle block 7.
