[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] The utility model provides a cold storage panel connection structure, wherein an insert is fixed on the convex groove edge of the cold storage panel 1, and a fastener is embedded in the groove. After the insert is inserted into the fastener, there is no gap between the two, thereby preventing cold air from leaking and reducing the refrigeration effect of the cold storage.

[0023] Figure 1-Figure 5 The figure shows the overall structure of a cold storage panel connection structure of the utility model. Figure 1-Figure 5 A cold storage panel connection structure of this embodiment includes a convex groove 102 set on one side of the cold storage panel 1, a groove 103 set on the other side of the cold storage panel 1, and a buckle assembly is fixedly provided on the cold storage panel 1.

[0024] The buckle assembly includes an insert and a buckle. The insert is fixed in the middle of the side wall, and the buckle is fixed in the inner cavity of the groove 103.

[0025] When the lock head 7 slides over the head of the plug 2, the second spring 8 rebounds to make the lock head 7 move inwards, and the straight surface of the lock head 7 fits the straight surface of the head of the plug 2. When the plug 2 is pulled out, the straight surface of the lock head 7 pushes the top ring 3 close to the head of the plug 2. When the straight surface of the top ring 3 contacts the straight surface of the head of the plug 2, the top ring 3 lifts the lock head 7, and the plug 2 is continued to be pulled out. The lock column 6 slides along the top ring 3 and the inclined surface of the top of the plug 2, and finally the plug 2 is pulled out to be separated.

[0026] A locking assembly is fixedly connected to the inner cavity of the cold storage panel 1.

[0027] The locking assembly includes a limit column 9, which is fixed in the cold storage plate 1. The second spring 8 has a limit groove 501, and the limit groove 501 is passed through the limit column 9. The middle of the screw rod 5 is connected to the first helical gear 10 for rotation, and the middle of the surface of the cold storage plate 1 is connected to the rotating column 11 for rotation. One end of the rotating column 11 is fixedly connected to the second helical gear 12, and the second helical gear 12 is engaged with the first helical gear 10. When the rotating column 11 is rotated, the rotating column 11 drives the second helical gear 12 to rotate, and the second helical gear 12 drives the first helical gear 10 to rotate. The limit groove 501 on the screw rod 5 is passed through by the limit column 9, so the screw rod 5 cannot rotate with the first helical gear 10 and can only move toward the convex groove 102 under the action of the thread. The screw rod 5 drives the plug 2 to move, and the plug 2 drives another cold storage plate 1 to approach until the rotating column 11 can no longer be rotated and is installed in place.

[0028] Furthermore, a hexagonal groove is formed on the other end surface of the rotating column 11 to facilitate the use of a hexagonal wrench to rotate the rotating column 11.

[0029] Furthermore, a sealing plug 13 is fixedly connected to the middle of the surface of the cold storage panel 1 to prevent cold air from leaking from the rotating hole opened in the cold storage panel 1.

[0030] Furthermore, a sealing strip 14 is fixedly connected in the groove 103 to further improve the sealing performance of the connection between the two cold storage panels 1 .

[0031] Combine Figure 1-Figure 5 , a cold storage board connection structure of this embodiment, the specific use process is as follows: insert the plug 2 of one cold storage board 1 into the screw rod 5 fixedly connected to the other cold storage board 1, after the inclined surface of the head of the plug 2 is in contact with the inclined surface of the lock head 7, continue to insert the plug 2, the lock head 7 moves outward along the slope, at this time the second spring 8 is compressed, when the lock head 7 slides over the head of the plug 2, the second spring 8 rebounds to make the lock head 7 move inward, and after the straight surface of the lock head 7 is in contact with the straight surface of the head of the plug 2, the plug 2 can no longer be pulled out. At this time, use a hexagonal wrench to turn The rotating column 11 is turned, and the rotating column 11 drives the second helical gear 12 to rotate, and the second helical gear 12 drives the first helical gear 10 to rotate. The limiting groove 501 on the screw rod 5 is passed by the limiting column 9, so the screw rod 5 cannot rotate with the first helical gear 10 and can only move toward the convex groove 102 under the action of the thread. The screw rod 5 drives the plug 2 to move, and the plug 2 drives another cold storage plate 1 to move closer until the rotating column 11 cannot be turned and is installed in place. When it needs to be disassembled, the rotating column 11 is reversed, and the rotating column 11 drives the second helical gear 12 reverses, the second helical gear 12 drives the first helical gear 10 to reverse, and the screw rod 5 moves back under the action of the thread as the first helical gear 10 reverses. When the screw rod 5 moves back, the plug 2 continues to be inserted into the screw rod 5, and the inclined surface of the lock head 7 contacts the top ring 3. The plug 2 continues to be inserted, and the top ring 3 will be moved to the root of the plug 2 by the lock head 7. At this time, the first spring 4 is compressed. When the top ring 3 moves to the root of the plug 2, it continues to be inserted. The top ring 3 pushes the lock head 7 outward along the slope of the lock head 7. At this time, the second spring 4 is compressed. 8 is compressed. When the lock head 7 is fully lifted up, it begins to contact the inclined surface of the top ring 3. At this time, the first spring 4 and the second spring 8 rebound at the same time. The first spring 4 rebounds the top ring 3 to its original position, and the lock head 7 is also rebounded to its original position by the second spring 8. At this time, the plug 2 is pulled out, and the straight surface of the lock head 7 pushes the top ring 3 close to the head of the plug 2. When the straight surface of the top ring 3 contacts the straight surface of the head of the plug 2, the top ring 3 lifts the lock head 7, and the plug 2 continues to be pulled out. The lock column 6 slides along the inclined surface of the top ring 3 and the top of the plug 2. Finally, the plug 2 is pulled out and can be removed.
