It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] The utility model provides a cold storage insulation door drive auxiliary device, including a door frame 1, the door frame 1 is fixedly connected to the open part of the cold storage, the door frame 1 is symmetrically provided with a closed structure 2, the top of the door frame 1 is installed with a receiving groove 101, the upper part of the receiving groove 101 is hinged with a cover plate 3, the cover plate 3 is movably connected to the upper part of the door frame 1, the closed structure 2 includes a door panel 201, a protective door 202 is slidably provided in the door panel 201, the door frame 1 is arranged on the outside of the cold storage entrance 4, a rectangular plate 203 is fixedly connected to the protective door 202, ... A hydraulic cylinder 204 is fixedly connected, and a telescopic rod 205 is movably connected to the hydraulic cylinder 204. The telescopic rod 205 is fixedly connected to the rectangular plate 203. The hydraulic cylinder 204 is operated and controlled by a staff member. The hydraulic cylinder can work continuously at low temperatures. A slide groove 206 is provided on the door panel 201, and the rectangular plate 203 can be slidably set in the slide groove 206. The rectangular plate 203 slides in the slide groove 206 to complete the sliding of the protective door 202 in the door frame 1. A thermal insulation plate 6 is embedded on the inner wall of the cover plate 3. The thermal insulation plate 6 is made of a low thermal conductivity material.

[0018] When the cold storage insulation door driving auxiliary device is actually used, the cold storage entrance 4 position needs to be closed and the staff operates the hydraulic cylinder 204 to start driving work, and the telescopic rod 205 in the hydraulic cylinder 204 drives the rectangular plate 203 fixedly connected to the protective door 202 to slide on the door frame 1, and the rectangular plate 203 slides in the slide groove 206 to complete the sealing work at the cold storage entrance 4 position. Since the door frame 1 is fixedly installed with a sealing ring 5, the sealing performance of the abutment position of the protective door 202 and the door frame 1 is greatly improved. The hydraulic cylinder 204 for driving the protective doors 202 on both sides from the two sides to the middle position is installed and limited in the prefabricated receiving groove 101 on the top of the door frame 1 to prevent external debris or low temperature and harsh environment from affecting the normal use of the hydraulic cylinder 204. A cover plate 3 is hinged at the open position of the receiving groove 101. In actual use, a cover plate 3 is hinged and rotatable, and an insulation plate 6 structure is installed at the bottom position of the cover plate 3. The insulation plate 6 is made of low thermal conductivity material as a whole, which ensures that the temperature at the position of the cover plate 3 is reduced. The protection of the internal working environment of the receiving groove 101 is completed. The receiving groove 101 is prefabricated on the door frame 1, and a sealing structure for driving the protective door 202 to slide in the door panel 201 is installed in the receiving groove 101. Compared with the conventional hinged and rotatable protective door 202 plate 201 structure, the technical solution adopted by the utility model prefabricates the driving structure in the door frame 1, and then the protective door 202 is slidably set in the door frame 1 as a whole, thereby improving the maneuverability and flexibility of the overall structure. The overall structure is compact and easy for staff to install and maintain. The structure is stable and not prone to failure, thereby reducing the maintenance cost of the overall structure.

[0019] like Figure 1-2 As shown, the protective doors 202 on both sides abut against each other, a sealing ring 5 is fixedly connected to the door frame 1, a handle 302 is fixedly connected to the cover plate 3, a protrusion 301 is fixedly connected to the cover plate 3, and the protrusion 301 is clamped with the door frame 1.

[0020] The effect achieved by the entire embodiment 1 is that, during use, the sealing ring 5 is fixedly installed on the door frame 1, so that the sealing performance at the abutment position between the protective door 202 and the door frame 1 is greatly improved, and a handle 302 is installed on the cover plate 3 to facilitate the staff to operate the cover plate 3 to flip it as a whole, and then the protrusion 301 is embedded in the door frame 1.

[0021] Working principle: The entrance of the cold storage needs to be closed and the staff operates the hydraulic cylinder to start driving. The telescopic rod in the hydraulic cylinder drives the rectangular plate fixedly connected to the protective door to slide on the door frame. The rectangular plate slides in the slide groove to complete the sealing work at the entrance of the cold storage. Since a sealing ring is installed and fixed on the door frame, the sealing at the abutment position of the protective door and the door frame is greatly improved. The hydraulic cylinder used to drive the protective doors on both sides from both sides to the middle position is installed and limited in the prefabricated receiving groove on the top of the door frame to avoid external debris or low temperature and harsh environment affecting the normal use of the hydraulic cylinder. A cover plate is hinged at the open position of the receiving groove. In actual use, the cover plate is rotatable by hinge. An insulation board structure is installed at the bottom wall of the cover plate. The insulation board is made of low thermal conductivity material as a whole to ensure that the temperature at the cover plate position is reduced and the speed of temperature reduction is reduced, thereby completing the protection of the working environment inside the receiving groove.
