[0002] A double-support chain is a chain with a double support structure, which is used to support and transmit force or movement. The original single chain support is changed to two chains that interlock with each other to improve the support strength and operation stability of the chain. However, when the chain is used to support windows outdoors and drive the windows to be recovered and pushed out, the chain is exposed to the outdoors for too long, and dust and impurities will accumulate on the surface of the chain. As a result, the chain drives dust and impurities into the storage bin during the recovery process, causing jamming when the window is subsequently pushed to move. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-3 A double support chain shown includes a base a1 and a base b9 installed on the rear side of the base a1;

[0026] A driving shaft 8 is disposed between the base a1 and the base b9 and close to the left and right sides respectively;

[0027] A top plate 4 is fixedly connected at the center of the upper outer wall of the base a1 and the base b9;

[0028] A chain a6 is arranged between the base a1 and the base b9, and a chain b7 is arranged on the outer wall of the left end of the chain a6. One end of the chain a6 and the chain b7 are connected to the window, and the drive shaft 8 is rotated to drive the chain a6 and the chain b7 to be pushed outward at the same time, so as to drive the window to be opened. When the window needs to be closed, the drive shaft 8 is rotated counterclockwise to drive the chain a6 and the chain b7 to be recovered at the same time, so as to drive the window to be closed.

[0029] A rear plate 12 is provided at the center of the upper outer wall of the base a1 and the base b9, and a brush a10 is provided on one side of the opposite surfaces of the two rear plates 12 to clean the front and rear sides of the chain a6 and the chain b7. Brushes b14 are provided on the lower side of the two brushes a10 and on the left and right sides respectively to clean the left and right sides of the chain a6 and the chain b7. Brushes c15 are provided on the opposite sides of the two brushes b14 near the front side. During the recycling process of the chain a6 and the chain b7, the brush a10 will be used to brush off the dust and impurities accumulated on the front and rear surfaces of the chain a6 and the chain b7. At the same time, the brushes b14 and c15 will be used to clean the left and right sides and the dust and impurities inside the chain a6 and the chain b7, and the dust and impurities will be brushed off to avoid dust accumulation.

[0030] like Figure 3 and Figure 4 As shown, a fixing plate 11 is fixedly connected between the two brushes a10 and the rear plate 12 to limit the position of the brush a10, and a limiting rod 13 is fixedly connected to the front outer wall of the rear plate 12 and close to the left and right sides to limit the position of the brush b14 and the brush c15.

[0031] The positions of the brushes a10, b14 and c15 are limited respectively by the fixing plate 11 and the limiting rod 13, so as to prevent the chains a6 and b7 from moving with the brushes a10, b14 and c15.

[0032] like Figure 5 As shown, a slot 19 opening upward is provided at the center of the upper outer wall of the two top plates 4, and a connecting block 17 is fixedly connected to the inside of the two slots 19, and a block 18 penetrating downwardly into the slot 19 is fixedly connected to the lower outer wall of the two rear plates 12, and a fixing screw 16 penetrating downwardly into the inside of the connecting block 17 is provided on the upper outer wall of the two blocks 18 to limit the position of the rear plate 12.

[0033] When it is necessary to replace the brush a10, the brush b14 and the brush c15, the fixing screw 16 can be unscrewed counterclockwise, the two rear plates 12 can be taken out, the rear plate 12 with the new brushes a10, the brush b14 and the brush c15 can be taken out, the block 18 at the lower end of the rear plate 12 can be inserted into the slot 19 and abutted against the connecting block 17, and then the block 18 and the connecting block 17 can be tightened and fixed by the fixing screw 16.

[0034] like Figure 3 and Figure 5 As shown, the two connecting blocks 17 and the clamping block 18 are provided with upwardly open threaded holes for screwing the fixing screws 16, and the two brushes a10 are both inclined.

[0035] The brush a10 is inclined, and can guide the dust accumulated on the surfaces of the chains a6 and b7 to the left and right sides during cleaning, thereby increasing the cleaning speed of the dust.

[0036] like Figure 1 and Figure 2 As shown, the front end outer wall of the driving shaft 8 is fixedly connected to the fixing rod 2, the front end outer wall of the fixing rod 2 is fixedly connected to the handle 3 near the right side, a plurality of connecting rods 5 are equidistantly arranged between the base a1 and the base b9, and the two driving shafts 8 are respectively engaged with the chain a6 and the chain b7.

[0037] When controlling the drive shaft 8 to rotate, the drive shaft 8 can be driven to rotate synchronously by grasping the handle 3 and rotating it clockwise. At the same time, the rotation directions of the drive shafts 8 on the left and right sides are opposite, which can drive the chain a6 and the chain b7 to be recovered. Rotating the handle 3 counterclockwise can drive the drive shaft 8 to rotate so that the chain a6 and the chain b7 extend outward.

[0038] like Figure 1 and Figure 2 As shown, a stopper is fixedly connected between the base a1 and the base b9 near the lower side, and the drive shaft 8 can rotate clockwise and counterclockwise to drive the chain a6 and the chain b7 to extend and retract.

[0039] The block can be used to lift and limit the position of chain a6 and chain b7 during the recovery process of chain a6 and chain b7.

[0040] The implementation principle of this embodiment is: connect one end of chain a6 and chain b7 to the window, and rotate the drive shaft 8 to drive chain a6 and chain b7 to be pushed outward at the same time, so as to drive the window to open. When the window needs to be closed, the drive shaft 8 can be rotated counterclockwise to drive chain a6 and chain b7 to be recovered at the same time, so as to drive the window to close. In the process of recovering chain a6 and chain b7, the brush a10 will be used to brush off the dust and impurities accumulated on the front and rear surfaces of chain a6 and chain b7. At the same time, the brush b14 and brush c15 will be used to clean the dust and impurities on the left and right sides and inside of chain a6 and chain b7, and the dust and impurities will be brushed off to avoid dust accumulation.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
