Technical Field

[0001] The utility model belongs to the technical field of cold storage, and particularly relates to a sealing structure of a cold storage door which is easy to operate. Background Art

[0002] A cold storage refers to a device that creates an environment with a temperature or humidity different from that outdoors by artificial means, and is also a constant temperature and humidity storage device for items such as food, liquid, chemical industry, medicine, vaccines, and scientific experiments. In order to isolate the internal and external environments of the cold storage when goods and people enter and exit the cold storage, a cold storage door needs to be installed at the entrance and exit of the cold storage.

[0003] In the Chinese patent with the publication number CN219589260U, a sealing structure of a cold storage door for hotel factory canteens is disclosed. Through the provided buffer assembly, when using this cold storage door, it is possible to prevent the staff from vigorously pushing the cold storage door, resulting in the cold storage not closing tightly, reducing the generation of gaps between the cold storage doors, making the cold storage more airtight. At the same time, through the provided buffer assembly, the cold storage door can only be slowly pushed to close, reducing the probability of damage to the cold storage door, making the cold storage more airtight and having a longer service life.

[0004] However, in the above comparative document, only the clamping and fixing between two silica gel blocks are achieved through a long rod and an arc-shaped rod, without a multi-lock structure, and the sealing strength is weak. Moreover, the setting of the buffer assembly requires a greater force to close the cold storage door, which is time-consuming and laborious and not easy to operate. Therefore, it is urgent to improve the existing sealing structure of the cold storage door and provide a sealing structure of the cold storage door that is easy to operate. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a cold storage door sealing structure with reasonable design, simple structure, higher sealing performance and easy to operate, aiming to solve the problems existing in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The mounting rod rotates within the inner cavity structure of the closing door. One end of the mounting rod is connected to the closing door by a bearing. The front end of the mounting rod is fixedly connected with a mounting disc. Two guide grooves that are symmetrically centered about its center are formed inside the mounting disc. The two movable rods are respectively slidably located in the middle of the upper and lower ends of the closing door. Fixed columns are fixedly connected to the front of the ends of the two movable rods that are close to each other.

[0010] As a preferred embodiment, the end of the mounting rod away from the mounting disc is snap-fitted inside the second positioning groove. The sliding directions of the two movable rods are always opposite. The end of the fixed column away from the movable rod is slidably guided inside the guide groove.

[0011] As a preferred embodiment, one end of the movable rod is snap-fitted inside the first positioning groove. Inclined surfaces are provided on both the end of the movable rod and the inner wall of the first positioning groove.

[0012] As a preferred embodiment, the locking mechanism includes a first limiting sleeve, a limiting rod, an L-shaped rod, a spring and a second limiting sleeve.

The L-shaped rod passes through and is slidably connected inside the first limiting sleeve. The left end of the L-shaped rod is slidably sleeved outside the limiting rod. The spring is sleeved outside the right end of the limiting rod. The left and right ends of the spring are respectively fixedly connected to the L-shaped rod and the first limiting sleeve. The second limiting sleeve is fixedly installed in the middle of the right side of the wall body. The right end of the L-shaped rod is snap-fitted inside the second limiting sleeve.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the solution of the present utility model:

[0015] Manually controlling the synchronous clockwise rotation of the mounting disc and the mounting rod can make the end of the mounting rod snap into the second positioning groove to achieve the preliminary positioning of the closing door. And when the mounting disc rotates, through the two guide grooves formed inside it, the two fixed columns can be respectively squeezed and the two movable rods can be pushed to move in the direction away from each other until the ends of the movable rods are inserted into the first positioning groove, so as to achieve the double positioning effect of the closing door. The locking effect of the closing door is better and more stable;

[0016] Since the end of the movable rod and the inner wall of the first positioning groove are both provided with inclined surfaces, during the process of the movable rod sliding and inserting into the first positioning groove, the movable rod can be subjected to a backward extrusion force, so as to press the closing door towards the wall, and the rubber sealing gasket can be extruded, which is convenient for using the rubber sealing gasket to fully seal between the closing door and the wall, with better sealing effect. And compared with the comparative document, the control of this sealing structure is more convenient and easier to operate. Moreover, by inserting one end of the L-shaped rod into the second limiting sleeve, the mounting disc can be limited, and the sealing state of the closing door can be ensured to be stable.

Detailed Embodiment

[0028] The embodiments described below are only a part of the embodiments of the present utility model and do not represent all embodiments consistent with the present utility model. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:

[0029] As Figure 1-8 shown, the easy-to-operate cold storage door sealing structure of the present utility model includes a wall body 1. An installation groove 2 is provided inside the wall body 1. First positioning grooves 3 are provided in the middle inner walls at the upper and lower ends of the installation groove 2. A second positioning groove 4 is provided in the middle position of the right inner wall of the installation groove 2. A rubber sealing pad 5 is pasted on the rear inner wall of the installation groove 2. A closing door 6 is rotatably connected inside the installation groove 2. A sealing mechanism 7 is installed in the middle of the closing door 6. A locking mechanism 8 is installed at the front end of the sealing mechanism 7.

[0030] Based on the above structure, a cavity structure is provided inside the closing door 6, and the longitudinal section of the cavity structure is fan-shaped.

[0031] Based on the above structure, the sealing mechanism 7 includes an installation rod 71, an installation disc 72, a guiding groove 73, a movable rod 74 and a fixing column 75. The installation rod 71 rotates in the internal cavity structure of the closing door 6. One end of the installation rod 71 is connected to the closing door 6 by a bearing. The front end of the installation rod 71 is fixedly connected with the installation disc 72. Two guiding grooves 73 that are centrosymmetric about its center are provided inside the installation disc 72. The two movable rods 74 slide respectively in the middle of the upper and lower ends of the closing door 6. Fixing columns 75 are fixedly connected to the front sides of the mutually approaching ends of the two movable rods 74.

[0032] In this embodiment, by rotating the installation disc 72 to drive the installation rod 71 to rotate synchronously, the end of the installation rod 71 can be rotated and inserted into the second positioning groove 4, so as to realize the preliminary positioning of the closing door 6. The fan-shaped cavity structure provided inside the closing door 6 facilitates the rotational adjustment of the installation rod 71.

[0033] Based on the above structure, the end of the installation rod 71 away from the installation disc 72 is clamped inside the second positioning groove 4. The sliding directions of the two movable rods 74 are always opposite. The end of the fixing column 75 away from the movable rod 74 is guided and slides inside the guiding groove 73.

[0034] In this embodiment, when the installation disc 72 rotates, by using the two guiding grooves 73 provided inside it, the two fixing columns 75 can be respectively squeezed and the two movable rods 74 can be pushed to move in the mutually separating direction until the end of the movable rod 74 is inserted into the first positioning groove 3, so as to realize the double positioning effect of the closing door 6.

[0035] Based on the above structure, one end of the movable rod 74 is clamped inside the first positioning groove 3. Inclined surfaces are provided on the end of the movable rod 74 and the inner wall of the first positioning groove 3.

[0036] In this embodiment, since inclined surfaces are provided on the end of the movable rod 74 and the inner wall of the first positioning groove 3, during the process of the movable rod 74 sliding and inserting into the first positioning groove 3, the movable rod 74 can be subjected to a backward extrusion force, so that the closing door 6 can be pressed towards the wall 1, and the rubber gasket 5 can be used to fully seal between the closing door 6 and the wall 1, and the sealing effect is better.

[0037] On the basis of the above structure, the locking mechanism 8 includes a first limiting sleeve 81, a limiting rod 82, an L-shaped rod 83, a spring 84 and a second limiting sleeve 85. The first limiting sleeve 81 is fixed at the outer edge of the front end of the mounting plate 72. A limiting rod 82 is fixed on the left side wall of the front end of the first limiting sleeve 81. An L-shaped rod 83 is penetrated and slidably connected inside the first limiting sleeve 81. The left end of the L-shaped rod 83 is slidably sleeved outside the limiting rod 82. A spring 84 is sleeved outside the right end of the limiting rod 82. The left and right ends of the spring 84 are respectively fixedly connected to the L-shaped rod 83 and the first limiting sleeve 81. The second limiting sleeve 85 is fixedly installed in the middle of the right side of the wall 1, and the right end of the L-shaped rod 83 is clamped inside the second limiting sleeve 85.

[0038] In this embodiment, the spring 84 can push the L-shaped rod 83 to move rightward along the limiting rod 82. After one end of the L-shaped rod 83 is inserted into the second limiting sleeve 85, the mounting plate 72 can be limited, and the sealing state of the closing door 6 can be ensured to be stable.

[0039] The working principle of the present utility model is as follows:

[0040] When it is necessary to seal the cold storage entrance and exit, first push the L-shaped rod 83 to the left to make the spring 84 in a stretched state, then turn the closing door 6 into the installation groove 2 correspondingly opened in the wall 1, and then manually control the mounting plate 72 and the mounting rod 71 to rotate synchronously in the clockwise direction, so that the end of the mounting rod 71 can be clamped into the second positioning groove 4 to realize the preliminary positioning of the closing door 6. At the same time, when the mounting plate 72 rotates clockwise, it can respectively squeeze the two fixing columns 75 through the two guiding grooves 73 opened inside it and push the two movable rods 74 to move in the direction away from each other until the end of the movable rod 74 is inserted into the first positioning groove 3, and the double positioning effect of the closing door 6 can be realized, and the locking effect of the closing door is better and more stable;

[0041] Such as Figure 2 and Figure 5As shown in the figure, since the end of the movable rod 74 and the inner wall of the first positioning groove 3 are both provided with inclined surfaces, during the process of the movable rod 74 sliding and inserting into the first positioning groove 3, the movable rod 74 can be subjected to a backward extrusion force, so as to press the closing door 6 towards the wall 1, and the rubber gasket 5 can be extruded, which is convenient to make full use of the rubber gasket 5 to seal between the closing door 6 and the wall 1. The sealing effect is better. Compared with the comparative document, the control of this sealing structure is more convenient and easier to operate;

[0042] After the sealing door 6 is closed, the L-shaped rod 83 can be released, so that it can stably move rightward and reset along the limiting rod 82 through the spring 84, and the right end of the L-shaped rod 83 is inserted into the second limiting sleeve 85, then the mounting disc 72 can be limited, and the sealing state of the closing door 6 can be ensured to be stable.

[0043] The above are only the preferred specific embodiments of the present invention, and are not intended to limit the protection scope of the present invention; any equivalent changes, modifications, substitutions and variations made by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments shall be within the protection scope determined by the claims.
