[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0029] According to Figures 1 to 3As shown in the figure, a buffer for a sunshade of the present utility model includes a pressing plate 1 and a fixing seat 2 installed on the pressing plate 1. The fixing seat 2 is fixed to the pressing plate 1 by screws. A conversion head 3 is provided on the fixing seat 2, and an active rod 4 and a fixed rod 5 are further provided on the conversion head 3. These two active rods 4 respectively pass through an active cavity 6 and a fixed cavity 7 inside the fixing seat 2. In order to achieve the buffering function, an elastic element 8 is installed in the active cavity 6. This elastic element 8 can provide the necessary resilience during the movement of the sunshade, slow down the movement of the active rod 4, and thus achieve the buffering effect. The active cavity 6 is designed as an oblong hole, which helps the active rod 4 to slide more smoothly and flexibly in the cavity. The fixed cavity 7 is a circular hole, so that the fixed rod 5 will not move. A buffer groove 10 is also provided inside the active cavity 6, and the elastic element 8 is installed in this buffer groove 10. A compression nut 9 is provided on one side of the fixing seat 2. A threaded hole 11 matching the elastic element 8 is provided on the fixing seat 2. The compression nut 9 is threadedly connected to this threaded hole 11. One end of the elastic element 8 abuts against the compression nut 9, and the other end abuts against the active rod 4. By rotating the compression nut 9, the compression degree of the elastic element 8 can be adjusted, thereby changing the buffering force of the active rod 4.
[0030] A limiting groove 20 is also provided on one side of the active cavity 6. In order to prevent the active rod 4 from disengaging or moving excessively during movement, the limiting groove 20 and the active cavity 6 are separated by a retaining rib 33. A limiting through hole 12 is provided on the fixing seat 2, and a screw rod 13 is inserted through the limiting through hole 12. An internal nut 14 is installed in the limiting groove 20, and an external nut 15 is provided on the outside of the fixing seat 2. Both the internal nut 14 and the external nut 15 are threadedly connected to the screw rod 13. Since the internal nut 14 is fixed, by adjusting the external nut 15, the entry and exit of the screw rod 13 can be effectively controlled, and thus the movement range of the active rod 4 can be adjusted.
[0031] Upper bushings 16 and lower bushings 17 are respectively sleeved on the active rod 4 and the fixed rod 5. The upper bushings 16 are installed in the active cavity 6, and the lower bushings 17 are installed in the fixed cavity 7. The main function of these bushings is to reduce the friction between the active rod 4, the fixed rod 5 and the fixing seat 2, effectively reduce the direct contact with the cavity wall during movement, thereby reducing wear, reducing noise, and extending their service life.
[0032] According to Figures 4 to 7As shown in the figure, a sunshade of the present utility model includes a first guide rail 22 and a second guide rail 23. The sunshade main body 24 is installed between these two guide rails. In order to ensure the flexible extension of the sunshade, a telescopic assembly 25 is equipped below the sunshade main body 24. A movable seat 26 is installed on the first guide rail 22, and a fixed seat 2 is installed on the second guide rail 23. The telescopic assembly 25 includes a first folding rod 27 and a second folding rod 28. Among them, one end of the first folding rod 27 is fixedly connected to the movable seat 26 through a rotational connection, and one end of the second folding rod 28 is connected to a conversion head 3 through a rotating shaft 32. The conversion head 3 is provided with a shaft hole 31. The rotating shaft 32 passes through the shaft hole 31 and is fixed on the second folding rod 28, enabling the second folding rod 28 to rotate flexibly around the rotating shaft 32. When the sunshade is subjected to external forces, it can effectively disperse stress. With the action of the buffer for the sunshade, the overall device is more stable and durable.
[0033] The upper end of the pressing plate 1 is designed with a convex rib 18 that bends towards the fixed seat 2. An upper mounting groove 19 is formed between the convex rib 18 and the upper end of the fixed seat 2. The lower end of the pressing plate 1 is provided with a lower hook 21. Corresponding to the pressing plate 1, the upper end of the guide rail is provided with an upper hook 29. The upper hook 29 can be accurately inserted into the upper mounting groove 19 of the pressing plate 1. The lower end of the guide rail is also provided with a lower mounting groove 30, and this mounting groove is used to accommodate the lower hook 21 on the pressing plate 1. By inserting the lower hook 21 into the lower mounting groove 30, two fixed points, upper and lower, are formed, achieving a firm fixation and ensuring the use safety of the sunshade in various environments. Especially in strong winds or adverse weather conditions, it can effectively prevent the structure of the sunshade from deforming or being damaged.
[0034] When the present utility model is in use, the width of the sunshade main body 24 is adjusted by moving the position of the first guide rail 22. At this time, the first folding rod 27 and the second folding rod 28 rotate. Since the second folding rod 28 is rotatably connected to the conversion head 3, the second folding rod 28 drives the movable rod 4 to move to buffer the movement of the second folding rod 28. Since the movable cavity 6 is a long waist-shaped hole, the movable rod 4 has a movable space towards the first guide rail 22. The compression and extension of the elastic element 8 will absorb part of the energy to prevent the first movable rod 4 from moving excessively. By adjusting the compression nut 9, the user can adjust the compression degree of the elastic element 8, thereby changing the pressing degree of the movable rod 4. By adjusting the outer nut, the entry and exit of the screw rod 13 can be effectively controlled, and then the movable range of the movable rod 4 can be adjusted.
[0035] The beneficial effects brought by the present utility model are:
[0036] The buffer can effectively absorb and slow down the impact force generated during the movement of the sunshade, prevent structural damage, and extend the service life of the sunshade.
[0037] The compression nut allows users to adjust the compression degree of the elastic element as needed, thereby controlling the buffering effect and adapting to different usage environments and requirements.
[0038] By adjusting the outer nut, the movement of the screw rod can be effectively controlled, and thus the movement range of the movable rod can be adjusted.
[0039] The above are only the preferred embodiments of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features, and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
