DETAILED DESCRIPTION

[0028] See also Figures 1 to 5 As shown, the utility model provides a cold storage panel connection structure for connecting two cold storage panels, including a cold storage panel body 1, a connection frame 21, a connection column 30, a ring 35, an elastic member 34, two rotating rods 32, two connecting rods 36 and two positioning blocks 24.

[0029] One side of the cold storage board body 1 is provided with an insertion block 10. Positioning grooves 11 are arranged on the upper and lower side walls of the insertion block 10. The other side of the cold storage board body 1 is provided with a docking block 20. An installation cavity is arranged in the docking block 20, and the installation cavity is open on the side far from the cold storage board body 1; a connecting frame 21 is fixed in the installation cavity, and the connecting frame 21 is arranged in a "C" shape to form a docking groove 22 at the opening. The docking groove 22 is adapted to the insertion block 10. Fixing holes 23 are arranged on the upper and lower side walls of the connecting frame 21; when two adjacent cold storage board bodies 1 are connected, when the insertion block 10 is inserted into the docking groove 22, the fixing holes 23 are communicated with the positioning grooves 11; a connecting column 30 is arranged in the middle of the installation cavity, and both ends of the connecting column 30 are respectively fixed on the inner wall of the installation cavity and the side wall of the connecting frame 21; a collar 35 is sleeved outside the connecting column 30 and is slidably connected with the connecting column 30; an elastic member 34 is fixed between one side wall of the connecting frame 21 and the collar 35. Preferably, the elastic member 34 is a spring. The spring is sleeved on the connecting column 30, and both ends of the spring 34 are fixed on one side wall of the connecting frame 21 and the collar 35. One ends of two rotating rods 32 are respectively rotatably connected to the upper and lower side walls of the end of the connecting column 30, and the other ends are respectively fixed with support rods 33. The two support rods 33 are arranged at intervals outside the upper and lower side walls of the connecting frame 21; one ends of two connecting rods 36 are respectively rotatably connected to the upper and lower sides of the collar 35, and the other ends are respectively rotatably connected to the two rotating rods 32; two positioning blocks 24 are respectively fixed on the opposite sides of the two support rods 33, so that the other ends of the two positioning blocks 24 extend downward to penetrate through the fixing holes 23.

[0030] When two adjacent cold storage boards are connected, the insertion block 10 on one cold storage board body 1 is inserted into the docking groove 22 on the other cold storage board body 1. During insertion, the upper and lower end faces of the insertion block 10 squeeze the two positioning blocks 24 into the fixing holes 23, causing the two rotating rods 32 to turn away from each other, and at the same time driving the two connecting rods 36 to rotate to a larger included angle, so that the collar 35 moves away from the connecting frame 21, stretching the elastic member 34; when the insertion block 10 is completely inserted into the docking groove 22, the fixing holes 23 are communicated with the positioning grooves 11, so that when the elastic member 34 resets and retracts, it drives the connecting rods 36 and the rotating rods 32 to rotate, so that the positioning blocks 24 penetrate through the fixing holes 23 into the positioning grooves 11, completing the connection of the two cold storage boards. This structure is easy to connect. It only needs to insert the insertion block 10 into the docking groove 22, which saves time and effort.

[0031] Furthermore, a guiding surface is arranged at one end of the positioning block 24 close to the fixing hole 23, and the guiding surface is arranged on the side close to the opening.

[0032] By providing the guide surface, it is convenient for the insertion block 10 to push the positioning block 24 when being inserted, so that the positioning block 24 can be quickly pushed into the fixing hole 23 and further pushed into the docking groove 22 .

[0033] Preferably, the guide surface is an arc-shaped surface.

[0034] Furthermore, a through slot 40 is formed on the top of the docking block 20 , and an operating block 41 is fixedly connected to the support rod 33 outside the upper side wall of the connecting frame 21 , and the operating block 41 extends upward to the inside of the through slot 40 .

[0035] During use, when multiple cold storage panel bodies 1 are connected, if one of the cold storage panel bodies 1 is broken, it is necessary to take out this cold storage panel body 1 for replacement. At this time, by flipping the operating block 41 outward, the operating block 41 drives the rotating rod 32 to rotate, thereby driving the ring 35 to move. When the ring 35 moves, it drives another connecting rod 36 to rotate, so that the two positioning blocks 24 are disengaged from the positioning groove 11, and then the broken cold storage panel body 1 can be taken out for replacement. The structure is quick and convenient to install and disassemble.

[0036] Furthermore, a circle of first sealing strip 50 is fixedly connected to the outer side wall of the docking block 20 , and a circle of second sealing strip 51 is fixedly connected to a side wall of the cold storage panel body 1 close to the insertion block 10 .

[0037] After the two cold storage panels are connected, the first sealing strip 50 and the second sealing strip 51 are in surface contact, thereby reducing the gap at the connection of the cold storage panel body 1.

[0038] Furthermore, a circular arc protrusion 52 is provided on the edge of the second sealing strip 51 , and a corresponding circular arc groove 53 is provided on the opening of the first sealing strip 50 .

[0039] When the first sealing strip 50 is butted against the second sealing strip 51 , the arc protrusion 52 of the second sealing strip 51 is inserted into the arc groove 53 of the first sealing strip 50 , further reducing the gap at the connection of two adjacent cold storage panel bodies 1 .

[0040] Furthermore, a mounting groove 60 is provided on the top of the cold storage panel, and a mounting frame 61 is fixedly connected to the bottom of the cold storage panel, and the mounting groove 60 and the mounting frame 61 are adapted in shape.

[0041] When installing the cold storage panel body 1, not only the left and right sides of the cold storage panel need to be connected, but also the upper and lower parts need to be spliced. When the cold storage panel body 1 needs to be installed above the lower cold storage panel as a whole, first insert the installation frame 61 at the bottom of the upper cold storage panel body 1 into the installation groove 60 of the lower cold storage panel body 1, so as to achieve the positioning of the upper cold storage panel body 1, thereby facilitating the assembly of the upper cold storage panel.

[0042] Specifically, two clamping plates 31 are fixed to the upper and lower sides of the connecting column 30 respectively, the two clamping plates 31 are arranged at an interval, a movable shaft is fixed between the two clamping plates 31, and a through hole is provided at the end of the rotating rod 32, and the through hole is sleeved on the movable shaft.

[0043] The movable shaft is fixed by two clamping plates 31 , and one end of the rotating rod 32 is rotatably connected to the movable shaft.
