[0039] The buffer and anti-collision assembly 400 is used to protect the bottom of the thermal insulation door body 100. The buffer and anti-collision assembly 400 includes a buffer plate 401 slidably arranged on the inner wall of the U-shaped groove, and two groups of buffer springs 402 symmetrically fixed to the lower surface of the buffer plate 401. The bottom ends of the buffer springs 402 are fixedly connected to the inner bottom wall of the U-shaped groove. A contact switch 403 is fixed to the inner bottom wall of the U-shaped groove, and the contact switch 403 is electrically connected to the two synchronous motors 302 via a wire.
[0040] A buffer pad 404 is fixedly provided on the upper surface of the buffer plate 401 , and the buffer pad 404 is made of elastic rubber, which can effectively protect the contact portion between the bottom of the thermal insulation door body 100 and the buffer plate 401 .
[0041] In this embodiment, the vertically movable cold storage insulated door with an anti-collision structure is equipped with a buffer anti-collision component 400 and a drive component 300, so that during the closing process of the insulated door, the bottom of the insulated door body 100 can be effectively prevented from being hit when closing, thereby achieving the purpose of effectively preventing the bottom of the insulated door body 100 from being hit.
[0042] Example 2
[0043] Based on the first embodiment, and different from the first embodiment,
[0044] A vertically movable cold storage insulation door with an anti-collision structure, further comprising:
[0045] The sealing assembly 500 is used to seal between the thermal insulation door body 100 and the cold storage wall 200.
[0046] The sealing assembly 500 includes a connecting plate 501 arranged at the bottom end of the thermal insulation door body 100, and a plurality of inflatable airbag columns 502 are fixedly arranged at equal intervals on the upper surface of the connecting plate 501, and the top end of the inflatable airbag column 502 is fixedly connected to the bottom end of the thermal insulation door body 100.
[0047] An annular mounting groove is provided on the back of the thermal insulation door body 100 , and a sealing airbag ring 503 is fixed to the inner wall of the annular mounting groove. The surfaces of the several inflatable airbag columns 502 are provided with connecting tubes for connecting the several inflatable airbag columns 502 with the sealing airbag ring 503 .
[0048] Two symmetrical limiting columns 504 are fixedly provided on the upper surface of the connecting plate 501, and a cylindrical groove 505 is provided at the bottom end of the thermal insulation door body 100, which is slidably connected to the outer surfaces of the two limiting columns 504. A reset spring 506 is sleeved on the outer surface of the limiting column 504, and the two ends of the reset spring 506 are respectively fixedly connected to the upper surface of the connecting plate 501 and the bottom end of the thermal insulation door body 100. The setting of the reset spring 506 facilitates the resetting of the connecting plate 501.
[0049] In this embodiment, the vertically movable cold storage insulated door with an anti-collision structure can achieve effective sealing of the insulation door body 100 during the downward movement of the insulation door body 100 by setting a sealing component 500, and can also play a certain buffering role, thereby further achieving effective protection of the bottom of the insulation door body 100.
[0050] During operation, the thermal insulation door, in the process of closing, can drive the two synchronous motors 302 to drive the two threaded columns 303 to rotate at the same time. The simultaneous rotation of the two threaded columns 303 drives the four sliders 304 to move downward at the same time, thereby driving the thermal insulation door body 100 to automatically move downward, realizing the automatic closing of the cold storage thermal insulation door. When the bottom of the thermal insulation door body 100 contacts the buffer pad 404 on the buffer plate 401, the thermal insulation door body 100 continues to move downward. Under the action of the buffer spring 402, the downward force of the thermal insulation door body 100 can be effectively buffered. At the same time, when the buffer plate 401 contacts the contact switch 403, the contact switch 403 automatically controls the two synchronous motors 302 to close, thereby effectively This avoids the situation where the bottom of the thermal insulation door body 100 encounters an impact when the thermal insulation door body 100 is closed, thereby achieving the purpose of effectively preventing the bottom of the thermal insulation door body 100 from being hit. In addition, in the process of the thermal insulation door body 100 moving downward, when the thermal insulation door body 100 is pressed against the buffer plate 401, the inflatable airbag column 502 can be squeezed, so that the gas in the inflatable airbag column 502 can enter the sealing airbag ring 503, causing the sealing airbag ring 503 to expand, so that the sealing airbag ring 503 is effectively pressed against the surface of the cold storage wall 200, thereby achieving effective sealing of the thermal insulation door body 100, and also playing a certain buffering role, further achieving effective protection of the bottom of the thermal insulation door body 100.
