[0014] The utility model is further configured as follows: a silicone block is installed on the side wall of the first connecting strip to prevent the first door panel and the second door panel from directly contacting and colliding with each other, and the width of the silicone block is greater than the thickness of the door panel.

[0015] In summary, the utility model has at least the following advantages:

[0016] 1. When the warehouse door needs to be folded, the handle is pulled to the left by hand, and the pulley in the sliding assembly on the first door panel is driven to move on the slide rail while the first door panel is moved. The first door panel is rotated by the first rotating shaft and the second rotating shaft, and the second door panel is folded together with the first door panel by means of a hinged connection between the first rotating shaft and the first door panel. This method makes the resistance during folding smaller, making the warehouse door more convenient and quick to fold;

By setting a fixing component, after the barn door is folded, the clamping block set on the side wall of the second connecting strip is inserted into the fixing seat, and the folded first door panel and the second door panel are fixed under the action of the first spring and the fixing block, so as to avoid the first door panel and the second door panel from sliding after folding. By setting a T-slot and a T-block in the side wall of the fixing block and the fixing seat, the fixing block is more stable when moving, and the fixing block is prevented from shaking left and right. By installing an L-shaped connecting plate on the side wall of the second connecting strip and slidingly connecting it to the guide rail, the connection strength between the pulley, the second connecting strip and the guide rail is strengthened, so that the pulley is more stable when moving.

[0018] 3. By dividing the card-joint block into two parts, namely, a card joint and a connecting block, the card joint is slidably installed in the connecting block, and a second spring is installed between the inner wall of the connecting block and the card joint. Under the action of the card joint, the connecting block and the second spring, the second door panel and the first door panel are prevented from direct collision when being folded. The second spring plays a buffering role, and a trapezoidal groove is provided on the side wall of the fixing seat. A silicone sheet is pasted on the surface of the trapezoidal groove. The silicone sheet allows the card-joint block to be buffered when entering the fixing seat, thereby preventing the card joint from directly colliding with the trapezoidal groove and thus damaging the fixing seat. The setting of the silicone block prevents direct contact and collision between the first door panel and the second door panel. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting bar 302 is divided into a first connecting bar 3021 and a second connecting bar 3022. The first connecting bar 3021 is fixed to the door panel 1, and the pulley 301 is rotatably mounted on the second connecting bar 3022. The second connecting bar 3022 is hoisted on the slide rail 2 through the pulley 301. One sliding assembly 3 is fixed on the guide rail, and the fixing method can be welding, bolting or other methods of fixing;

[0028] The first connecting strip 3021 and the second connecting strip 3022 are connected by a first rotating shaft 4, and the lower surface of the first door panel 101 is rotatably connected to the ground by a second rotating shaft 5. A handle 6 is installed on the outer wall of the second door and close to the hinge of the first door panel 101. A silicone block 13 is installed on the side wall of the first connecting strip 3021 to prevent the first door panel 101 and the second door panel 102 from direct contact and collision. The width of the silicone block 13 is greater than the thickness of the door panel 1, and an L-shaped connecting plate 12 is installed on the side wall of the second connecting rod. The L-shaped connecting plate 12 is slidably connected to the guide rail. The L-shaped connecting plate 12 strengthens the connection strength between the pulley 301, the second connecting strip 3022 and the guide rail, so that the pulley 301 is more stable when moving.

[0029] like Figure 3As shown, a fixing component 7 for fixing the folded first door panel 101 and the second door panel 102 is provided at one end of the guide rail, and the fixing component 7 includes a fixing seat 701 fixedly installed on the side wall of the guide rail and a clamping block 702 installed on the side wall of the second connecting strip 3022, a plurality of first springs are symmetrically arranged on the inner wall of the fixing seat 701, and a fixing block 703 for fixing the clamping block 702 is installed on the surface of the first spring, and T-slots 8 are symmetrically provided on the left and right sides of the fixing block 703, and arc chamfers are provided at the edge positions where the fixing block 703 contacts the clamping block 702, and T-blocks 9 matching the arc grooves are fixed on the two inner side walls of the fixed top seat, and the cross-sectional area of ​​the fixing block 703 is an isosceles triangle, and the T-slots 8 and the T-blocks 9 make the fixing block 703 more stable when moving, thereby preventing the fixing block 703 from shaking left and right.

[0030] like Figure 4 As shown, the clamping block 702 is composed of a clamping joint 7021 and a connecting block 7022. The cross-sectional area of ​​the clamping joint 7021 is hexagonal. One end of the clamping joint 7021 is slidably installed in the connecting block 7022. A second spring 10 is installed between the inner wall of the connecting block 7022 and the clamping joint 7021. A trapezoidal groove is opened on the side wall of the fixing seat 701, and a silicone sheet 11 is pasted on the surface of the trapezoidal groove.

[0031] The working process and beneficial effects of the utility model are as follows:

[0032] When the barn door needs to be folded, the handle 6 is pulled to the left by hand, and the pulley 301 in the sliding assembly 3 on the first door panel 101 is driven to move on the slide rail 2 while moving. While moving, the first door panel 101 rotates through the first rotating shaft 4 and the second rotating shaft 5, and the second door panel 102 is folded together with the first door panel 101 by means of a hinged connection between the first rotating shaft 4 and the first door panel 101. This method makes the resistance during folding smaller, making it more convenient and quick to fold the barn door;

[0033] After the warehouse door is folded, the clamping block 702 set on the side wall of the second connecting strip 3022 is inserted into the fixing seat 701, and the positions of the first door panel 101 and the second door panel 102 after folding are fixed under the action of the first spring, the fixing block 703 and the clamping block 702, so as to avoid the first door panel 101 and the second door panel 102 from sliding after folding. By dividing the clamping block 702 into two parts, namely the clamping joint 7021 and the connecting block 7022, the clamping joint 7021 is slidably installed in the connecting block 7022, and the second spring 10 is installed between the inner wall of the connecting block 7022 and the clamping joint 7021, under the action of the clamping joint 7021, the second door panel 102 and the first door panel 101 are prevented from direct collision when folding, and the second spring 10 plays a buffering role.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
