Description

Technical Field

[0001] The utility model belongs to the technical field of sunshade frames, in particular to a sunshade frame which is convenient for replacing sunshade cloth. Background Art

[0002] In the summer, strong sunlight will be reflected into the room in the form of diffuse light, making the room brighter, but too strong sunlight will also increase the indoor temperature and affect the service life of the furniture. Therefore, it is often necessary to use a sunshade frame equipped with a sunshade cloth to block the sunlight.

[0003] Publication No. "CN213509890U" discloses "an outdoor sunshade frame for green buildings". The relative positions of the right turn plate and the left turn plate are changed by adjusting the extension of the hydraulic telescopic column. The left end of the left turn plate is away from the spring frame. At this time, the turntable and the rotating rod are simultaneously pulled away from the spring frame, and the sunshade cloth wrapped on the automatic reel is lengthened. At this time, the range of blocking sunlight is increased. At the same time, the adjustment component can be used to adjust the angle of the device, which can better adjust the shading effect.

[0004] The above technical solution still has the following shortcomings during implementation:

[0005] After repeated use, the elastic properties of the disc spring will decrease, affecting the subsequent stretching and winding of the sunshade cloth. At the same time, there is a lack of corresponding quick disassembly and assembly mechanism. When the sunshade cloth needs to be reinstalled and replaced, the sunshade cloth cannot be quickly disassembled and replaced, resulting in the installation, fixation, disassembly and replacement of the sunshade cloth being more troublesome, increasing the difficulty of maintaining the sunshade cloth.

[0006] In view of the above problems, we propose a sunshade frame which is convenient for replacing sunshade cloth. Utility Model Content

[0034] Example:

[0035] When installing the sunshade cloth 2, first adjust the strip plate 9 at one end of the sunshade cloth 2 to insert it into the corresponding cavity 8 through the strip groove on the rotating rod 4. Under the elastic action of the first spring 11, combined with the hinge action of the clamping plate 10, the clamping plate 10 is pressed outward until the movable end of the clamping plate 10 abuts against the inner wall of the cavity 8, so that one end of the sunshade cloth 2 is fixed on the rotating rod 4;

[0036] According to the same principle, the other end of the sunshade cloth 2 is fixed on the fixed rod 7, and the excess sunshade cloth 2 is rolled up on the rotating rod 4;

[0037] When the shielding range of the sunshade cloth 2 is adjusted, the servo motor 23 is started, and the first bevel gear 17 is driven to rotate by the servo motor 23. Under the meshing action of the first bevel gear 17 and the second bevel gear 18, and the meshing action of the second bevel gear 18 and the third bevel gear 19, the screw rod 5 and the rotating rod 4 are driven to rotate synchronously;

[0038] The sunshade cloth 2 is released by rotating the rotating rod 4, and at the same time, the screw rod 5 is rotated, combined with the sliding cooperation between the guide block 21 and the guide rod 20, to drive the fixed rod 7 to move away from the rotating rod 4, thereby pulling the released sunshade cloth 2 to move away, effectively expanding the shielding range of the sunshade cloth 2;

[0039] When disassembling the sunshade cloth 2, press the movable plate 13 into the movable groove 12 to squeeze the second spring 16 and drive the push plate 15 to move in the direction of the strip groove. As the push plate 15 moves, the clamping plate 10 is squeezed into the groove, thereby facilitating the removal of the strip plate 9 from the corresponding cavity 8, thereby facilitating the disassembly and replacement of the sunshade cloth 2.

[0040] Compared with the prior art, the utility model drives the first bevel gear 17 to rotate through the servo motor 23, combines the meshing action of the first bevel gear 17 and the second bevel gear 18, cooperates with the rotating shaft, drives the screw rod 5 on the front side to rotate, and combines the meshing action of the second bevel gear 18 on the front side and the third bevel gear 19 on the front side, drives the rotating rod 4 to rotate, and releases the sunshade cloth 2. At the same time, under the action of the second bevel gear 18 on the rear side and the third bevel gear 19 on the rear side, it drives the screw rod 5 on the rear side to rotate synchronously, and under the thread cooperation of the screw rod 5 and the threaded tube 6, combined with the sliding cooperation of the guide block 21 and the guide rod 20, the adjustment threaded tube 6 is screwed out to a distance, and then drives the fixed rod 7 to move in the direction away from the rotating rod 4, stretches the released sunshade cloth 2 to a distance, increases the shielding range of the sunshade cloth 2, and solves the problem that after repeated use in the prior art, the elastic performance of the disc spring will be reduced, affecting the subsequent stretching and winding of the sunshade cloth 2.

[0041] At the same time, with the mutual cooperation between the strip plate 9 and the strip groove, it is convenient to adjust the strip plate 9 to be inserted into the cavity 8. Combined with the first spring 11, the card plate 10 is squeezed outward, so that the card plate 10 is stuck in the cavity 8, and then the strip plate 9 is fixed in the cavity 8, which is convenient for the fixation of the two ends of the sunshade cloth 2. Combined with the active cooperation of the movable plate 13 and the positioning rod 14, it is convenient to press the movable plate 13 inward, drive the push plate 15 to move into the cavity 8, and squeeze the card plates 10 on both sides in the direction close to the strip plate 9 until the card plate 10 is separated from the inner wall of the cavity 8, so as to facilitate the removal of the strip plate 9 from the corresponding cavity 8, and then facilitate the rapid disassembly of the two ends of the sunshade cloth 2, which solves the problem of lack of corresponding rapid disassembly and assembly mechanism in the prior art. When the sunshade cloth 2 needs to be reinstalled and replaced, the sunshade cloth 2 cannot be quickly disassembled and replaced, which makes the installation, fixation and disassembly and replacement of the sunshade cloth 2 more troublesome, and increases the difficulty of maintenance of the sunshade cloth 2.

[0042] It should be further explained that the installation structure, connection method or setting method of each component in the utility model are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented. At the same time, the servo motor 23 in the utility model is purchased on the market, and those skilled in the art can install and use it according to the requirements;

[0043] The adjustment component 26 in the present invention is a prior art that has been disclosed in the comparative documents, and its specific structure and use method will not be described in detail here.
