DETAILED DESCRIPTION

[0028] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0029] like Figure 1 , Figure 2 As shown, a specific embodiment of the utility model discloses an elastic module, including a first support shaft 300, a coil spring 400 is wound around the outer side of the first support shaft 300, an outer cover of the coil spring 400 is provided with a shell 500, and the first support shaft 300 is rotatably installed on the shell 500; the shell 500 is provided with a first bayonet 510 for clamping with a rolling curtain rod, and the coil spring 400 provides rotational elastic force for the first support shaft 300.

[0030] The above-mentioned elastic module, during assembly, the outer shell and the rolling curtain rod are clamped and matched synchronously; the first support shaft and the outer shell are connected and matched through a coil spring, and the coil spring will be retracted during the rotation of the rolling curtain rod, thereby providing corresponding elastic force; as an independent module, it can be installed in the rolling curtain to provide the required elastic force to meet the corresponding retraction action.

[0031] Furthermore, if Figure 3As shown, a first clamping groove 310 is provided on the outer side of the first support shaft 300, a clamping head 320 is fixedly provided at the bottom of the first clamping groove 310, and one end of the coil spring 400 is sleeved on the outer side of the clamping head 320; the clamping head includes a convex column and a convex head fixedly provided at the end of the convex column, and a strip opening is provided at one end of the coil spring, and the coil spring is sleeved at the clamping head through the strip opening; during installation, the strip opening can be sleeved from the convex head, and then the direction of the coil spring can be adjusted so that the strip opening is clamped under the convex head to achieve effective connection and matching;

[0032] A second bayonet 520 is provided on one side of the first bayonet 510, and a card is fixedly provided on the other end of the coil spring. The card can be extended from the second bayonet 520 and clamped on the outer side of the second opening 520, thereby limiting the other end of the coil spring, so that the two ends of the coil spring are respectively connected and cooperated with the first support shaft and the outer shell; the coil spring 400 is rolled up inside the outer shell 500, and the outer shell is used to limit the outside of the coil spring so that it maintains a rolled-up state, so as to provide the required elastic force later.

[0033] Furthermore, if Figure 4 , Figure 5 As shown, the shell 500 includes a shell 530 with one side open, and a shell cover 540 is provided on the outer side cover of the open mouth of the shell 530, a first bayonet 510 is provided on the side wall of the shell 530, and the shell cover 540 is provided with a notch 541 corresponding to the first bayonet; the centers of the shell 530 and the shell cover 540 are correspondingly provided with a through hole 550, the first support shaft 300 movably passes through the shell 530 and the shell cover 540 through the through hole 550, and the first support shaft is rotatably installed on the shell through a retaining spring; the shell is a detachable structure, and the first support shaft and the coil spring are also separable structures, which can facilitate the processing and production of various components, and the overall assembly method is also relatively simple, which is convenient for assembly and production.

[0034] Furthermore, if Figure 6 As shown, the interior of the shell gradually narrows toward the first bayonet, forming a downward pressure surface biased toward the inner side, which can limit the coil spring so that the coil spring can be better rolled up inside the shell, thereby providing a stronger winding elastic force.

[0035] Furthermore, a plug post 531 is fixedly provided on the outer side of the open mouth of the shell 530, and a corresponding plug hole is provided on the shell cover 540; the shell cover is arranged on the outer side of the open mouth of the shell, and the plug post is correspondingly inserted into the plug hole; the alignment and installation between the shell cover and the shell can be facilitated, so that the notch corresponds to the position of the first bayonet, so as to be snap-fitted with the inside of the rolling shutter rod.

[0036] Furthermore, a second card slot 543 is provided at the edge of the shell cover 540; a second card block 532 is fixed on the wall of the shell 530 away from the opening, and the second card block is adapted to the shape of the second card slot and has a corresponding position; this structural design is mainly used for the structure of the elastic module of multiple coil springs, such as Figure 7 , Figure 8 As shown, when the length of the first support shaft is long enough to cover more than two coil springs, it means that there are two shells, and the two shells can be matched through the second clamping block and the second clamping slot to move synchronously and provide greater winding force;

[0037] It should be noted that if Figure 7 , Figure 8 As shown, the length of the first support shaft can be preset in advance to several commonly used specifications, including but not limited to being able to be wound with one / two / three coil springs, and can be selected and combined accordingly according to actual needs to meet different elastic force requirements.

[0039] It should be pointed out that in addition to the above-mentioned method of connecting and cooperating through the first sleeve and the first support shaft, it is also possible to further combine the length of the first support shaft with a method of sleeved with different numbers of coil springs to achieve more combinations, thereby meeting different elastic force requirements; more specifically, initially, an elastic module with multiple coil springs can be selected, and then other elastic modules can be added according to actual use, so as to better adjust according to actual needs.
