Description

Technical Field

[0001] This utility model relates to the field of sealing technology for isolation doors, specifically a sealed isolation door for retrieving goods from a freezer. Background Technology

[0002] Freezers preserve objects by lowering their internal temperature. They consist of a cabinet, door frame, and door, with the door sealing the cabinet in contact with it.

[0003] Traditional freezer doors move up and down, sealing the freezer when they come into contact with the cabinet. However, this movement creates a gap between the door and the cabinet for easy access. Since the freezer operates with cold air, this cold air leaks out through the gap, requiring continuous freezing and resulting in poor freezing performance.

[0004] To address the aforementioned issues, a sealed isolation door for retrieving goods from a freezer is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a sealed isolation door for retrieving goods from a freezer, which solves the problem of cold air leaking out from gaps in traditional freezers, and also solves the problem of insufficient sealing in traditional freezers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealed isolation door for retrieving goods from a freezer, comprising: a frame; a door body located inside the frame and slidably connected to the frame; guide plates are fixedly connected to both sides of the inner side of the frame, and curved guide rails are provided at opposite ends of the guide plates; two sets of guide blocks are fixedly connected to both sides of the door body, the guide blocks are located inside the curved guide rails and slidably connected to the curved guide rails; a transmission mechanism is provided on the outer side wall of the frame, and the transmission mechanism is fixedly connected to the door body through a fixing clamp.

[0007] As a further description of the above technical solution: the transmission mechanism includes a motor, a transmission roller, a rotating roller and a synchronous belt. The motor is fixedly connected to the outer wall of the frame, the output shaft of the motor is fixedly connected to the transmission roller, the transmission roller passes through the frame, and rotating rollers are rotatably connected to the top of both sides of the frame. A synchronous belt is sleeved on the outer side of the transmission roller and the rotating roller on the same side, and a fixing clamp is fixedly connected to the inner wall of the synchronous belt. The fixing clamp has a stepped structure.

[0008] As a further description of the above technical solution: the number of the curved guide rails is two sets, and they are interleaved.

[0009] As a further description of the above technical solution: the two guide blocks located on the same side are respectively located inside the two curved guide rails.

[0010] As a further description of the above technical solution: the inner wall of the frame is fixedly connected to a limiting block, and the limiting block is adapted to the fixing fixture.

[0011] As a further description of the above technical solution: a guide wheel is rotatably connected to the outer side of the guide plate, and the guide wheel is in contact with the door body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model provides a sealed isolation door for retrieving goods from a freezer. Through a design of two sets of interlaced curved guide rails, and with guide blocks for the door body located within each set of curved guide rails, the distance between the door body and the front of the frame is closer when closing upwards, resulting in a tighter contact and ensuring its sealing performance. A transmission mechanism allows the door body to move up and down, and a synchronous belt design ensures synchronized movement on both sides of the door body, preventing tilting. Limit blocks allow it to stop at designated positions, further enhancing the sealing effect. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] Combination Figure 1 , Figure 2 and Figure 3A sealed isolation door for retrieving goods from a freezer includes: a frame 1; a door body 2 located inside the frame 1 and slidably connected to the frame 1; guide plates 3 are fixedly connected to both sides of the inside of the frame 1, and curved guide rails 4 are provided at opposite ends of the guide plates 3; two sets of guide blocks 5 are fixedly connected to both sides of the door body 2, the guide blocks 5 are located inside the curved guide rails 4 and slidably connected to the curved guide rails 4; a transmission mechanism 6 is provided on the outer wall of the frame 1, the transmission mechanism 6 is fixedly connected to the door body 2 through a fixing clamp 7; and guide wheels 9 are rotatably connected to the outer side of the guide plates 3, the guide wheels 9 being in contact with the door body 2.

[0021] The door 2 moves up and down on the frame 1 to achieve opening and closing. The curved guide rail 4 changes the position of the door 2 so that it is in closer contact with the cabinet. The guide block 5 allows it to slide freely in the curved guide rail 4, which plays a guiding role. The guide wheel 9 makes its up and down movement smoother.

[0022] Combination Figure 1 and Figure 3 The transmission mechanism 6 includes a motor 601, a transmission roller 602, a rotating roller 603, and a synchronous belt 604. The motor 601 is fixedly connected to the outer wall of the frame 1. The output shaft of the motor 601 is fixedly connected to the transmission roller 602. The transmission roller 602 passes through the frame 1. The rotating roller 603 is rotatably connected to the top of both sides of the frame 1. The synchronous belt 604 is sleeved on the outer side of the transmission roller 602 and the rotating roller 603 on the same side. The inner wall of the synchronous belt 604 is fixedly connected to a fixing clamp 7. The fixing clamp 7 has a stepped structure. The motor 601 drives the transmission roller 602 to rotate, which in turn causes the synchronous belt 604 to move, causing the rotating roller 603 to rotate synchronously. When the synchronous belt 604 rotates, it drives the fixing clamp 7 to move up and down, which in turn drives the door 2 to move up and down to achieve opening and closing. The fixing clamp 7 has a stepped structure and can be fixedly connected to both the synchronous belt 604 and the door 2.

[0023] Combination Figure 3 There are two sets of curved guide rails 4, which are intertwined. Two guide blocks 5 located on the same side are located inside the two curved guide rails 4 respectively. Limiting blocks 8 are fixedly connected to the inner wall of the frame 1. The limiting blocks 8 are adapted to the fixing clamps 7. The intertwined curved guide rails 4 can change the position distance of the door body 2 to achieve a better sealing effect.

[0024] Working principle: Motor 601 drives transmission roller 602 to rotate, which in turn causes synchronous belt 604 to move, causing rotating roller 603 to rotate synchronously. When synchronous belt 604 rotates, it drives fixed clamp 7 to move up and down, which in turn drives door 2 to move up and down to achieve opening and closing. Fixed clamp 7 has a stepped structure and can be fixedly connected to both synchronous belt 604 and door 2. Then, door 2 is moved upward to close, and door 2 is moved downward to detach from cabinet, achieving a better sealing effect.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
