Description

Technical Field

[0001] The utility model belongs to the technical field of cold storage buffer doors, in particular to an enhanced anti-collision cold storage buffer door. Background Art

[0002] The cold storage buffer door is a mechanical structure installed on the cold storage buffer room to isolate the space. It is mainly used to protect the interior after isolating the cold storage buffer room to prevent the intrusion of foreign objects or the loss of internal cold air. However, during the closing process, collisions will occur at the contact point of the door. After multiple times, the installation point may become loose or the collision point may deform, resulting in the problem of being unable to seal. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an enhanced anti-collision cold storage buffer door, which realizes the function of buffering and preventing collision after closing, and avoids the problem of loosening or deformation and inability to seal due to multiple collisions.

[0004] The technical solution is as follows: an enhanced anti-collision cold storage buffer door, including a door panel body, a lower sliding rail and an upper sliding rail, the left and right sides between the lower sliding rail and the upper sliding rail are movably embedded and connected to the door panel body; a bidirectional screw is threadedly connected to the upper side of the door panel body; a gear box is embedded in the end of the bidirectional screw; a servo motor is installed on the front bolt of the bidirectional screw; a buffer touch pad structure is installed on the inside of the door panel body; a servo motor is installed on the front bolt of the gear box; the servo motor is electrically connected to the PLC, and is characterized in that the buffer touch pad structure includes a pad strip, a pressure sensor is embedded in the pad strip; a mounting hole is opened on the upper part of the pad strip; a cleaning and processing seat structure is opened on the lower side of the pad strip.

[0005] Preferably, the cushion strip is a rubber strip and is glued to the inner side of the door panel body.

[0006] Preferably, the pressure sensor is provided in plurality and is electrically connected to the PLC, and the front end of the PLC is electrically connected to a button.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] In the utility model, the arrangement of the lower sliding rail and the upper sliding rail enhances the stability of the door panel when it slides.

[0009] In the utility model, the cushion strip is provided to provide buffering and anti-collision during the closing process, thereby avoiding the problem of loosening or deformation and failure to seal due to multiple collisions.

[0010] In the utility model, the pressure sensor is arranged to detect the pressure when the door panel is closed, so as to avoid poor sealing effect caused by too low pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] As attached Figure 2 As shown, in the above embodiment, specifically, the buffer touch pad structure 5 includes a pad strip 51, and a pressure sensor 52 is embedded in the pad strip 51; a mounting hole 53 is opened on the upper part of the pad strip 51; a cleaning processing seat structure 54 is opened on the lower side of the pad strip 51; the door panel body 1 is closed with the cooperation of the lower slide rail 2 and the upper slide rail 3, and the pad strips 51 at the ends contact each other during the closing process, and the pressure is detected by the pressure sensor 52 at the same time.

[0020] As attached Figure 3 As shown, in the above embodiment, specifically, the cleaning treatment seat structure 54 includes a seat body 541, and a mounting cavity 542 is opened inside the seat body 541; cleaning brushes 543 are glued to the left and right sides of the inner wall of the mounting cavity 542; during the movement of the door panel body 1, the seat body 541 and the cleaning brush 543 at the bottom will clean the dust on the lower rail 2

[0024] How it works

[0025] The working principle of the utility model is as follows: in the process of isolating the cold storage buffer room, the servo motor 7 is driven to rotate the bidirectional screw 4 with the cooperation of the gear box 6, so that the door panel body 1 is closed with the cooperation of the lower slide rail 2 and the upper slide rail 3. During the closing process, the pads 51 at the ends contact each other, and the pressure is detected by the pressure sensor 52. In this way, the cold storage buffer room can be closed and isolated after buffering and at a suitable pressure. During the movement of the door panel body 1, the seat 541 and the cleaning brush 543 at the bottom will clean the dust on the lower slide rail 2.
