Technical Field

[0001] The present invention relates to the technical field of installation node structures, and particularly to a thermal insulation installation node structure for a cold storage door opening. Background Art

[0002] As an important part of the cold chain logistics, cold storages are mainly used for storing and preserving goods that require a low-temperature environment, such as fresh produce, frozen products, medicines, etc. With the rapid development of the prefabrication industry, prefabricated cold storages are used more and more widely.

[0003] The existing thermal insulation and sealing doors of prefabricated cold storages generally adopt a top-hanging form to reduce resistance, and the rollers roll in the tracks. However, when the thermal insulation and sealing door is subjected to a large force, the moving speed of the thermal insulation and sealing door is too fast. At this time, there is a problem that the thermal insulation and sealing door will collide with the frame, resulting in deformation of the thermal insulation and sealing door, cold air loss, and poor thermal insulation effect; Therefore, we designed a thermal insulation installation node structure for a cold storage door opening to solve the above problems.

[0007] Preferably, the moving mechanism includes two hanging blocks fixedly connected to the top of the thermal insulation and sealing door, a rotating shaft is penetrated through each hanging block and is rotatably connected thereto, rollers are fixedly connected to the front and rear ends of each rotating shaft, rolling grooves are formed on the U-shaped fixing plate, and the four rollers are located in the rolling grooves and are rotatably connected thereto.

[0008] Preferably, the buffer mechanism includes a connecting rod that penetrates through the U-shaped fixing plate and is slidably connected thereto. One end of the connecting rod away from the U-shaped fixing plate is fixedly connected to a buffer plate. One end of the connecting rod away from the buffer plate is fixedly connected to a sealing block. A sealing groove is formed in the U-shaped fixing plate. The sealing block is located in the sealing groove and is slidably sealed therewith. A plurality of damping holes are formed through the sealing block. A spring is fixedly connected between the side wall of the sealing block and the inner wall of the sealing groove. The sealing groove is filled with damping liquid.

[0009] Preferably, the limiting mechanism includes a threaded rod that penetrates through the heat-insulating and sealing door and is rotatably connected thereto. One end of the threaded rod away from the heat-insulating and sealing door is fixedly connected to a handle. A moving plate is sleeved on the outer wall of the threaded rod and is threadedly connected thereto. A sliding cavity is formed in the heat-insulating and sealing door. The moving plate is arranged in the sliding cavity. Two sliding rods are fixedly connected to the inner wall of the heat-insulating and sealing door. Both of the two sliding rods penetrate through the moving plate and are slidably connected thereto. Two positioning rods are fixedly connected to the back end of the moving plate. Both of the two positioning rods penetrate through the heat-insulating and sealing door and are slidably connected thereto. Two positioning holes are formed in the front surface of the wall body. The two positioning rods are respectively inserted into the positioning holes.

[0010] Preferably, a U-shaped rod is fixedly connected to the front surface of the heat-insulating and sealing door. A protective sleeve is sleeved on the outer wall of the U-shaped rod. The protective sleeve is made of silica gel.

[0011] Preferably, a buffer layer is arranged at one end of the buffer plate close to the heat-insulating and sealing door. The buffer layer is made of rubber.

[0017] 2. When the force for moving the heat-insulating and sealing door is large, the inertia is large at this time. The heat-insulating and sealing door will contact and collide with the buffer plate. The sealing block moves in the sealing groove to compress the spring, and the damping liquid in the sealing groove flows through multiple damping holes to generate a damping force. The combination of the deformation of the spring and the resistance of the liquid buffers the inertial collision impact of the heat-insulating and sealing door, avoiding the rigid collision between the heat-insulating and sealing door and the U-shaped fixing plate, which may cause deformation and damage to the heat-insulating and sealing door, and achieving a good heat-insulating effect.

[0018] 3. The staff holds the handle and rotates it to drive the threaded rod to rotate, so that the moving plate moves on the two sliding rods towards the wall. The movement of the moving plate drives the two positioning rods to move until the positioning rods are inserted into the positioning holes, completing the fixation of the heat-insulating and sealing door. The rectangular sealing ring provided at the rear end of the heat-insulating and sealing door abuts against the front surface of the wall to form a seal, which can block the cold storage door opening and prevent the cold air in the cold storage from leaking, playing a role in heat insulation.

[0019] In summary, the present invention can buffer and protect the heat-insulating and sealing door with large inertia through the buffer mechanism, avoiding the deformation of the heat-insulating and sealing door and achieving a good heat-insulating effect; through the limiting mechanism, the heat-insulating and sealing door can be limited, so that the sealing effect on the cold storage door opening is good and the protection effect is good.

Specific implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Refer to Figures 1-7 , a heat preservation installation node structure for a cold storage door opening, including a wall body 1, a cold storage door opening 2 is penetrated and opened on the wall body 1, a U-shaped fixing plate 3 is fixedly connected to the front surface of the wall body 1, a heat preservation and sealing door 4 is arranged on the front surface of the wall body 1, a U-shaped rod 9 is fixedly connected to the front surface of the heat preservation and sealing door 4, a protective sleeve is sleeved on the outer wall of the U-shaped rod 9, and the material of the protective sleeve is silica gel, which can increase comfort. The staff can push the heat preservation and sealing door 4 to move by holding the U-shaped rod 9.

[0030] A moving mechanism is arranged between the heat preservation and sealing door 4 and the U-shaped fixing plate 3. The moving mechanism includes two hanging blocks 5 fixedly connected to the top of the heat preservation and sealing door 4. A rotating shaft 6 is penetrated through each hanging block 5 and is rotatably connected thereto. The front and rear ends of each rotating shaft 6 are fixedly connected with a roller 7. A rolling groove 8 is opened on the U-shaped fixing plate 3. The four rollers 7 are located in the rolling groove 8 and are rotatably connected thereto. By rolling the rollers 7 in the rolling groove 8, the moving resistance of the heat preservation and sealing door 4 can be small, and when the heat preservation and sealing door 4 moves leftward, the cold storage door opening 2 is blocked, and when the heat preservation and sealing door 4 moves rightward, the cold storage door opening 2 is opened.

[0031] Both the left and right ends of the U-shaped fixing plate 3 are provided with symmetrical buffer mechanisms. The buffer mechanism includes a connecting rod 11 that penetrates through the U-shaped fixing plate 3 and is slidably connected thereto. One end of the connecting rod 11 away from the U-shaped fixing plate 3 is fixedly connected with a buffer plate 10. One end of the buffer plate 10 close to the heat preservation and sealing door 4 is provided with a buffer layer, and the material of the buffer layer is rubber. When the heat preservation and sealing door 4 collides with the buffer plate 10, the buffer rubber is provided to protect the heat preservation and sealing door 4. One end of the connecting rod 11 away from the buffer plate 10 is fixedly connected with a sealing block 12. A sealing groove 13 is formed in the U-shaped fixing plate 3. The sealing block 12 is located in the sealing groove 13 and is slidably and sealingly connected thereto. A plurality of damping holes 14 are formed through the sealing block 12. A spring 15 is fixedly connected between the side wall of the sealing block 12 and the inner wall of the sealing groove 13. The sealing groove 13 is filled with damping liquid 16. Through the deformation of the spring 15 and the flow of the damping liquid 16 through the damping holes 14, the heat preservation and sealing door 4 with a large impact force can be buffered and protected. A sliding port is formed through the U-shaped fixing plate 3, and the sliding port is communicated with the sealing groove 13. The connecting rod 11 penetrates through the sliding port and is slidably connected thereto. A sealing member is fixedly connected to the inner wall of the sliding port. The connecting rod 11 and the sealing member are hermetically arranged. By providing the sealing member, sealing can be ensured and the leakage of the damping liquid 16 can be avoided.

[0032] A limiting mechanism is provided on the heat preservation and sealing door 4. The limiting mechanism includes a threaded rod 18 that penetrates through the heat preservation and sealing door 4 and is rotatably connected thereto. One end of the threaded rod 18 away from the heat preservation and sealing door 4 is fixedly connected with a handle 17. A moving plate 19 that is threadedly connected to the outer wall of the threaded rod 18 is sleeved on the outer wall of the threaded rod 18. A through hole is formed through the moving plate 19. External threads and internal threads that are matched with each other are respectively provided on the outer wall of the threaded rod 18 and the inner wall of the through hole. A sliding cavity 20 is formed in the heat preservation and sealing door 4. The moving plate 19 is arranged in the sliding cavity 20. Two sliding rods 21 are fixedly connected to the inner wall of the heat preservation and sealing door 4. Both of the two sliding rods 21 penetrate through the moving plate 19 and are slidably connected thereto. Two positioning rods 22 are fixedly connected to the back end of the moving plate 19. Both of the two positioning rods 22 penetrate through the heat preservation and sealing door 4 and are slidably connected thereto. Two positioning holes 23 are formed in the front surface of the wall body 1. The two positioning rods 22 are respectively inserted into the positioning holes 23. When it is necessary to seal the cold storage door opening 2, the heat preservation and sealing door 4 is fixed by inserting the positioning rods 22 into the positioning holes 23.

[0033] A rectangular sealing ring 24 is fixedly connected to the back surface of the heat preservation and sealing door 4. The rear end of the rectangular sealing ring 24 abuts against the front surface of the wall body 1. The front surface of the rectangular sealing ring 24 and the back surface of the heat preservation and sealing door 4 are fixedly installed by bonding, so that the cold storage door opening 2 can be sealed and the heat preservation function can be realized.

[0034] In the present invention, when used in a cold storage, the staff can hold the U-shaped rod 9 to push the thermal insulation and sealing door 4 to move. When it is necessary to seal the cold storage door opening 2, the staff hold the U-shaped rod 9 and push the thermal insulation and sealing door 4 to move in front of the cold storage door opening 2. During the movement, the movement of the thermal insulation and sealing door 4 drives the two hanging blocks 5, the rotating shaft 6, and the rollers 7 to move. During this process, the rotating shaft 6 and the rollers 7 roll in the rolling grooves 8, making the movement of the thermal insulation and sealing door 4 stable and with little movement resistance; when the thermal insulation and sealing door 4 moves in front of the cold storage door opening 2, if the force for the movement of the thermal insulation and sealing door 4 is large and the inertia is large at this time, the thermal insulation and sealing door 4 will contact and collide with the buffer plate 10. The thermal insulation and sealing door 4 drives the buffer plate 10, the connecting rod 11, and the sealing block 12 to move. The sealing block 12 moves in the sealing groove 13 to compress the spring 15, and the damping liquid 16 in the sealing groove 13 flows through multiple damping holes 14 to generate a damping force. The combination of the deformation of the spring 15 and the resistance of the liquid buffers the inertial collision impact of the thermal insulation and sealing door 4, preventing the thermal insulation and sealing door 4 from rigidly colliding with the U-shaped fixing plate 3 and causing deformation and damage to the thermal insulation and sealing door 4. Moreover, the deformation force of the spring 15 is converted into the internal energy of the damping liquid 16, making the thermal insulation and sealing door 4 and the spring 15 finally tend to be stable; the staff hold the handle 17 and rotate it to drive the threaded rod 18 to rotate, making the moving plate 19 move towards the wall 1 on the two sliding rods 21. The movement of the moving plate 19 drives the two positioning rods 22 to move until the positioning rods 22 are inserted into the positioning holes 23, completing the fixation of the thermal insulation and sealing door 4. Moreover, the rectangular sealing ring 24 provided at the rear end of the thermal insulation and sealing door 4 abuts against the front surface of the wall 1 to form a seal, which can block the cold storage door opening 2 and prevent the cold air in the cold storage from flowing out, playing a role in heat preservation.
