Description

Technical Field

[0001] This utility model relates to the field of cold storage sliding door technology, and in particular to a cold storage sliding door. Background Technology

[0002] Cold storage is a type of refrigeration equipment. It refers to an environment created artificially to differ in temperature and humidity from the outside world. It's a constant-temperature, constant-humidity storage facility for items such as food, liquids, chemicals, pharmaceuticals, vaccines, and scientific research materials. Cold storage facilities are typically located near ports of transport or the point of origin. Compared to refrigerators, cold storage facilities have a larger refrigeration area and share the same refrigeration principle. To facilitate entry and exit, a main entrance is usually provided on one side of the cold storage unit. Furthermore, sliding doors are typically installed for insulation. However, the locking mechanisms of existing cold storage sliding doors are relatively cumbersome to operate.

[0003] For example, the cold storage sliding door disclosed in the authorization announcement number CN 221924180 U, although the buffer plate is made of high carbon steel, the high carbon steel has high strength, which can further improve the impact resistance. By turning on the motor, the two nuts can move in opposite directions, which can easily slide the two sealing doors into the sliding opening, thus making it easy to open the cold storage sliding door. By setting up an insulation board, and setting the insulation board to be a rigid polyurethane foam cold storage board, the rigid polyurethane foam cold storage board has the advantage of good heat insulation, which can prevent the problem of temperature transmission caused by large temperature difference between the inside and outside of the cold storage board.

[0004] However, this does not solve the problem of the cumbersome operation of the existing locking mechanism for cold storage sliding doors. Therefore, we propose a new type of cold storage sliding door. Utility Model Content

[0005] The purpose of this utility model is to provide a cold storage sliding door that solves the problem that the locking structure of existing cold storage sliding doors is relatively cumbersome to operate.

[0006] To achieve the above objectives, this utility model provides a cold storage sliding door.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A cold storage sliding door includes a storage rack 1, with mounting racks 6 fixedly installed on both sides of the storage rack 1. The mounting rack 6 has a sliding guide rail 8 inside. Two sliding door bodies 10 are movably installed above the mounting rack 6. An operating rack 14 is movably installed on the outside of the sliding door bodies 10. A functional compartment 15 is opened inside the sliding door body 10. A fixed lock frame 19 is fixedly installed inside the functional compartment 15. Locking rods 22 are movably installed on both sides of the fixed lock frame 19.

[0025] In this embodiment, preferably, a fixing frame 2 is fixedly installed on the outside of the storage frame 1, a sealing gasket 3 is fixedly installed on one side of the fixing frame 2, a plurality of fixing holes 4 are opened inside the fixing frame 2, and two storage grooves 5 are opened on the inside of the storage frame 1.

[0026] The above scheme uses the storage frame 1, the fixing frame 2, and the storage groove 5 to fix and install the sliding door.

[0027] In this embodiment, the mounting bracket 6 is fixedly installed on both sides of the receiving bracket 1 near the fixed bracket 2. A limit block 7 is fixedly installed above the mounting bracket 6. Sliding guide rails 8 are provided on both sides of the limit block 7 inside the mounting bracket 6. Locking holes 9 are provided inside the sliding guide rails 8.

[0028] The above scheme facilitates the installation of the sliding door body 10 by using the mounting bracket 6, limiting block 7, sliding guide rail 8, and locking hole 9, while also allowing for rapid movement using the sliding guide rail 8.

[0029] In this embodiment, the sliding door body 10 is movably disposed inside the storage frame 1 on the side near the sliding guide rail 8. An inner viewing window 11 is fixedly disposed inside the sliding door body 10. A push-pull handle 12 is fixedly disposed on the outside of the sliding door body 10. A limit lock 13 is fixedly disposed below the push-pull handle 12. An operating frame 14 is movably disposed on the outside of the sliding door body 10 on the side near the push-pull handle 12.

[0030] The above scheme, with the sliding door body 10, inner viewing window 11, push-pull handle 12, limit lock 13 and operating frame 14, facilitates the opening and closing of the sliding door and protects the cold storage.

[0031] In this embodiment, the functional compartment 15 is fixedly installed outside the inner window 11 inside the sliding door body 10. An insulation pad 16 is fixedly installed on the side of the functional compartment 15 away from the inner window 11. Sliding grooves 17 are opened on both sides of the functional compartment 15. A limit frame 18 is fixedly installed on the side of the functional compartment 15 near the sliding groove 17.

[0032] The above solution, through the functional compartment 15, the insulation pad 16 and the limiting frame 18, makes it convenient to use the insulation pad 16 to ensure the heat insulation of the sliding door body 10, thereby reducing the loss of cold storage temperature.

[0033] In this embodiment, the fixed lock frame 19 is fixedly installed on the side of the functional compartment 15 near the operating frame 14. Movable connecting frames 20 are movably installed on both sides of the fixed lock frame 19. Movable hinges 21 are fixedly installed at both ends of the movable connecting frame 20. A locking rod 22 is movably installed on one end of the movable connecting frame 20 near the limiting frame 18.

[0034] The above scheme, through the fixed lock frame 19, movable connecting frame 20, movable hinge 21 and locking rod 22, facilitates the quick locking of the sliding door body 10 using the crank slider mechanism.

[0035] Example 1: The staff can use the fixing frame 2 to fix this type of sliding door to the wall of the cold storage. A sealing gasket 3 is set at the contact point between the fixing frame 2 and the wall to prevent cold air leakage at the installation connection. When using this type of sliding door, the sliding door body 10 can be pushed and pulled by the push-pull handle 12, so that it can move back and forth parallel to both sides on the sliding guide rail 8 in the mounting frame 6, so as to facilitate the staff to open and close the sliding door body 10. At the same time, the limit block 7 and the push-pull handle 12 can limit the movement range of the sliding door. When the sliding door is closed, the position of the sliding door body 10 can be fixed by the limit lock 13. At the same time, the internal viewing window 11 can be used to observe the situation of the objects stored in the cold storage.

[0036] Example 2: This type of sliding door is also equipped with an operating frame 14 and a fixed lock frame 19. The operator can rotate the operating frame 14 clockwise to rotate the fixed lock frame 19, thereby using the fixed lock frame 19 to drive the movable connecting frame 20 to move. At this time, since the horizontal position of the locking rod 22 is restricted by the limiting frame 18, the movement of the movable connecting frame 20 will drive the locking rod 22 to move upward, so that it extends out of the functional compartment 15 and is locked in the locking hole 9, limiting the position of the sliding door body 10, thereby locking the sliding door. When it is necessary to open the sliding door, simply rotate the operating frame 14 in the opposite direction. When the sliding door body 10 is opened and moves to both sides, the operating frame 14 will be stored in the storage slot 5, thereby maximizing the opening range of the sliding door body 10.

[0037] In this embodiment, a sliding door for cold storage is used by workers to fix it to the wall of the cold storage using a mounting bracket 2. A sealing gasket 3 is installed where the mounting bracket 2 contacts the wall to prevent cold air leakage at the installation connection. When in use, the sliding door body 10 can be pushed and pulled using the push-pull handle 12, allowing it to move back and forth parallel to both sides on the sliding guide rail 8 within the mounting bracket 6. This facilitates opening and closing the sliding door body 10. The limiting block 7 and the push-pull handle 12 limit the range of movement of the sliding door. When the sliding door is closed, it can be opened and closed by hand. The position of the sliding door body 10 is fixed by the limit lock 13, and the condition of the cold storage stored objects can be observed through the inner viewing window 11. The advantages of this type of cold storage sliding door are that after the sliding door is installed using the fixing frame 2, the installation frame 6 and the storage frame 1 restrict the installation of the sliding door body 10. The push-pull handle 12 facilitates the operation of the sliding door body 10 by pulling it out and allowing it to slide laterally on the installation frame 6, thus facilitating the opening and closing of the sliding door. Simultaneously, the limit block 7 effectively limits the distance the sliding door body 10 moves to one side, allowing the operator to easily use the limit lock 13. To lock the sliding door, this type of sliding door is also equipped with an operating frame 14 and a fixed lock frame 19. The operator can rotate the operating frame 14 clockwise to rotate the fixed lock frame 19, thereby using the fixed lock frame 19 to drive the movable connecting frame 20. At this time, because the horizontal position of the locking rod 22 is restricted by the limiting frame 18, the movement of the movable connecting frame 20 will cause the locking rod 22 to move upward, thus extending it out of the functional compartment 15 and locking it in the locking hole 9, limiting the position of the sliding door body 10, thereby locking the sliding door. To open the sliding door, simply rotate the operating frame 14 in the opposite direction, and the sliding door body 10 will be locked. When the door is opened and moved to both sides, the operating frame 14 is stored in the receiving slot 5, thereby maximizing the opening range of the sliding door body 10. Another advantage of this type of cold storage sliding door is that the device uses a crank-slider mechanism to adjust the position of the locking rod 22 so that it can cooperate with the locking hole 9 to lock the position of the sliding door body 10. The operator only needs to rotate the operating frame 14 to lock and unlock the door, which is convenient for the operator to quickly lock or open the sliding door. At the same time, the crank-slider mechanism has a simple structure and a low probability of failure, which can effectively ensure the service life of this type of sliding door.
