[0013] Beneficial Effects

[0014] The utility model provides a cold storage door. Compared with the prior art, it has the following beneficial effects:

[0015] 1. The cold storage door is automatically closed after being opened under the drive of the automatic door closer, so there will be a collision between the cold storage door and the door frame. When the two cold storage doors are closed, the buffer structure on both sides of the baffle block has a buffering effect on the cold storage door, which plays a protective role for the cold storage door. When the cold storage door contacts the buffer structure, it first contacts the arc-shaped buffer block at one end thereof. Since it is made of rubber material, it plays a buffering role. At the same time, when the vibration force is generated, the damper on the rear end face of the arc-shaped buffer block also strengthens the damping and buffering effect. At the same time, the connecting rods connected by the movable shaft on both sides of the connecting block on the rear end face thereof will also be stretched to both sides, and at the same time, the guide block A connected by the movable shaft and sleeved on the outside of the guide rod A connected by the connecting rod will slide, so that the buffer spring B at one end of which is sleeved on the outside of the guide rod A is compressed, so as to buffer and reduce the vibration force. At the same time, the buffer rubber block on the lower end face of the connecting block contacts the inner wall of the buffer structure, and plays a buffering role at the same time.

[0016] 2. After the cold storage door is closed, the short shaft rotates to drive the gear to engage with the tooth groove of the inner wall and move to one side, while driving the plug block to move until it is inserted into the slot inside the fixed block on the front end of the cold storage door for fixation, thereby strengthening the closure of the two cold storage doors.

The cold storage doors 2 are first opened and then automatically closed under the drive of the automatic door closer 3, so there will be a collision between the cold storage doors 2 and the door frame 1. When the two cold storage doors 2 are closed, the buffer structures 11 on both sides of the blocking block 12 have a buffering effect on the cold storage doors 2, thereby protecting the cold storage doors 2;

[0025] A buffer spring B22 is provided below the two guide blocks A21 and is sleeved on the outside of the two guide rods A20. A plurality of evenly arranged dampers 14 are provided on the rear end face of the arc buffer block 13. A buffer spring A15 is sleeved on the outside of the damper 14. A connecting block 16 is provided on the rear end face of the damper 14. An arc block A17 is fixedly provided on both sides of the connecting block 16. A connecting rod 19 is provided between the arc block A17 and the arc block B23.

The front end face of the cold storage door 2 on one side is fixedly provided with a door locker 5, and the front end face of the cold storage door 2 on the other side is fixedly provided with fixing blocks 9 at both upper and lower ends. When the cold storage door 2 contacts the buffer structure 11, it first contacts the arc-shaped buffer block 13 at one end thereof. Since the arc-shaped buffer block 13 is made of rubber, it plays a buffering role. At the same time, when the vibration force is generated, the damper 14 at the rear end face of the arc-shaped buffer block 13 also strengthens the damping and buffering role;

[0026] A buffer rubber block 24 is fixedly provided on the rear end face of the connecting block 16, protrusions 29 are fixedly provided on both sides of the interior of the buffer structure 11, guide rods B27 are provided inside the two protrusions 29, a guide plate 25 is fixedly provided outside the buffer rubber block 24, a buffer spring C26 is sleeved on the outside of the buffer rubber block 24, guide blocks B28 slidably sleeved on the outside of the two guide rods B27 are provided on both sides of the guide plate 25, slots 10 are provided inside the two fixed blocks 9, and slide grooves 7 are provided at both ends of the front end face of the door lock 5.

[0027] During operation, the cold storage door 2 is first opened and then automatically closed under the drive of the automatic door closer 3, so there will be a collision between the cold storage door 2 and the door frame 1. When the two cold storage doors 2 are closed, the buffer structure 11 on both sides of the blocking block 12 has a buffering effect on the cold storage door 2, which plays a protective role for the cold storage door 2. When the cold storage door 2 contacts the buffer structure 11, it first contacts the arc-shaped buffer block 13 at one end thereof. Since it is made of rubber, it plays a buffering role. At the same time, when the vibration force is generated, the damper 14 on the rear end surface of the arc-shaped buffer block 13 also strengthens the damping and buffering effect. At the same time, the connecting rod 19 connected by the movable shaft 18 on both sides of the connecting block 16 of the rear end surface will also be pulled to both sides. The guide block A21 connected to the guide rod A20 and sleeved on the outside of the guide rod A20 connected by the movable shaft 18 is extended, and the connecting rod 19 is driven to slide, so that the buffer spring B22 with one end sleeved on the outside of the guide rod A20 is compressed, and the vibration force is buffered and reduced. At the same time, the buffer rubber block 24 on the lower end face of the connecting block 16 contacts the inner wall of the buffer structure 11 and plays a buffering role. After closing, the cold storage door 2 is rotated by the short shaft 31 to drive the gear 32 to engage with the tooth groove 30 of the inner wall and move to one side, and at the same time drive the plug block 8 to move until it is inserted into the slot 10 inside the fixed block 9 on the front end face of the cold storage door 2 for fixation, thereby strengthening the closure of the two cold storage doors 2.
