Description

Technical Field

[0001] This utility model relates to the field of outdoor folding chairs, specifically to an outdoor folding chair with an adjustable backrest angle. Background Technology

[0002] In modern society, more and more people enjoy outdoor activities during their leisure time to get closer to nature, such as camping, picnicking, and fishing. Portable and practical outdoor chairs are indispensable for these activities. Many types of outdoor chairs have emerged, such as simple folding benches and folding canvas chairs, which have captured the market due to their compact size and convenience.

[0003] However, most outdoor folding chairs currently available do not have the functions of adjusting seat height, adjusting backrest angle, or convenient handling. Therefore, this utility model proposes an outdoor folding chair with adjustable backrest angle to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides an outdoor folding chair with an adjustable backrest angle. Through the hinged relationship of the backrest and the setting of the adjustment locking rod, the angle of the backrest can be easily adjusted. By setting locking bolts and retractable support legs, the height of the folding chair can be adjusted. At the same time, the setting of the locking rod can not only fix the hollow support legs when unfolded for use, but also lock and limit the hollow support legs when stored. After the whole structure is stored, it is fixed and can be quickly carried by lifting it with the handle.

[0005] Technical solution

[0006] An outdoor folding chair with an adjustable backrest angle includes a seat cushion. A backrest is hinged to one side of the seat cushion. First threaded posts are provided on the front and rear sides of the backrest, and second threaded posts are provided on the front and rear sides of the seat cushion. An adjustment locking rod for locking the backrest angle is provided between the first threaded posts and the second threaded posts. Four fixing blocks are provided on the lower surface of the seat cushion. Hollow support legs are hinged to the fixing blocks. Support legs are slidably fitted into the hollow support legs. Several locking holes are passed through the support legs. Locking bolts that can engage with the locking holes are passed through and threaded onto the hollow support legs. A handle for easy handling and carrying is also provided on the seat cushion.

[0007] Furthermore, a third threaded post is fixed on the hollow support leg, and a locking rod is inserted between the two third threaded posts.

[0008] Furthermore, the third threaded post passes through both ends of the locking rod and is fixed by mounting bolts.

[0009] Furthermore, the first threaded post and the second threaded post respectively pass through both ends of the adjusting locking rod and are fixed by the mounting bolts.

[0010] Furthermore, a fourth threaded post is provided on the lower surface of the fixing block. The two ends of the locking rod are fitted into the fourth threaded post and fixed by the mounting bolt. After being fixed, the locking rod locks and limits the hollow support leg after it is folded.

[0011] Furthermore, a cushion is provided on the upper side of the backrest.

[0012] Beneficial effects

[0013] Compared with the prior art, this utility model has the following advantages: the hinged backrest and the adjustable locking rod allow for convenient adjustment of the backrest angle; the locking bolt and retractable support legs enable height adjustment of the folding chair; the locking rod not only secures the hollow support legs when unfolded but also locks and limits their movement when folded; the overall structure is fixed when folded, allowing for quick transport by lifting it with the handle; and the fully locked structure provides greater stability during use.

[0020] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:

[0021] have Figures 1-4As shown, this utility model discloses an outdoor folding chair with an adjustable backrest angle, including a seat cushion 1. A backrest 9 is hinged to one side of the seat cushion 1. First threaded posts 10 are provided on the front and rear sides of the backrest 9, and second threaded posts 12 are provided on the front and rear sides of the seat cushion 1. An adjusting locking rod 8 for locking the angle of the backrest 9 is provided between the first threaded posts 10 and the second threaded posts 12. Four fixing blocks 6 are provided on the lower surface of the seat cushion 1. Hollow support legs 5 are hinged to the fixing blocks 6. Support legs 2 are slidably fitted into the hollow support legs 5. Several locking holes 3 are passed through the support legs 2. Locking bolts 15 that can be locked into the locking holes 3 are passed through and threaded on the hollow support legs 5. The seat cushion 1 is also provided with a handle 7 for easy handling and carrying.

[0022] Furthermore, a third threaded post 4 is fixed on the hollow support leg 5, and a locking rod 14 is inserted between the two third threaded posts 4.

[0023] Furthermore, the third threaded post 4 passes through both ends of the locking rod 14 and is fixed by the mounting bolt 13.

[0024] Furthermore, the first threaded post 10 and the second threaded post 12 respectively pass through both ends of the adjusting locking rod 8 and are fixed by the mounting bolt 13.

[0025] Furthermore, a fourth threaded post 16 is provided on the lower surface of the fixing block 6. The two ends of the locking rod 14 are fitted into the fourth threaded post 16 and fixed by the mounting bolt 13. After being fixed, the locking rod 14 locks and limits the hollow support leg 5 after it is folded.

[0026] Furthermore, a cushion 11 is provided on the upper side of the backrest 9.

[0027] Specifically, when using a folding chair, rotate the hollow support leg 5 to a vertical position, then insert the two end holes of the locking rod 14 into the third threaded post 4, and then tighten the mounting bolts to fix it, thus fixing the hollow support leg 5.

[0028] Then, as needed, first unscrew the locking bolt 15, then pull out the support leg 2 to the required length, and then screw in the locking bolt 15 to fix the support leg 2, thereby adjusting the height of the folding chair;

[0029] Then, insert one end of the adjusting locking rod 8 into the appropriate second threaded post 12, then rotate the backrest 9 to the desired angle, then insert the hole at the other end of the adjusting locking rod 8 into the first threaded post 10, and then fix it with the mounting bolt 13 to achieve the angle adjustment and locking of the backrest 9;

[0030] When it is necessary to store and fold, remove the locking rod 14, then retract the support leg 2 into the hollow support leg 5, and fix the support leg 2 with the locking bolt 15;

[0031] Next, rotate the hollow support leg 5 until it is parallel to the seat cushion 1. Then, insert both ends of the removed locking rod 14 onto the fourth threaded post 16 and lock it with the mounting bolt 13. At this point, the hollow support leg 5 is locked in place by the two ends of the locking rod 14, which also achieves the storage and fixation of the locking rod 14 itself (e.g., Figure 3 );

[0032] Next, remove the adjusting lock lever 8, fold the backrest 9 until it is roughly parallel to the seat cushion 1, then reinstall the adjusting lock lever 8 and lock the backrest 9 in this position. This will allow the folding chair to be stored (e.g., Figure 2 );

[0033] Since the entire folding chair is now completely fixed and stored, it can be lifted up using handle 7 for easy handling and transport.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the technical solutions of this utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
