Detailed implementation manners

[0025] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the embodiments of the present utility model, and should not be construed as a limitation to the present utility model.

[0026] Embodiment 1

[0027] Referring to Figure 1 , this embodiment discloses an adjustable folding reclining chair, including an adjustable folding chair frame and a folding chair cloth arranged on the adjustable folding chair frame. The adjustable folding chair frame includes a chair frame body, and the chair frame body includes a support frame, a backrest frame connected to the support frame, and a leg frame. The backrest frame is rotatably connected to the support frame, and an angle adjustment device is arranged between the backrest frame and the support frame.

[0028] The support frame includes two support components. Each support component includes two legs 1 that are rotatably connected, a cross bar 2 that is hinged to the two legs 1, and two fork bars 3. One end of each fork bar 3 is rotatably connected to the cross bar 2, and the other end is rotatably connected to the leg 1. The two fork bars 3 are rotatably connected. The tops of the two legs 1 are rotatably connected by a clamping bar 12. The two fork bars 3 cross each other and are rotatably connected in the middle. By rotating the two fork bars 3, the entire support frame can be folded and stored.

[0029] The leg frame is rotatably connected to the support frame. The leg frame includes two leg support bars 4 that are rotatably connected. The leg support bars 4 are rotatably connected to the legs 1. The two leg support frames also cross each other and are rotatably connected in the middle. Therefore, when the two fork bars 3 are rotated and folded, the two leg support bars 4 can also be rotated and folded for storage. Moreover, since the two leg support bars 4 are rotatable with respect to the legs 1, the two leg support frames can be turned upwards to further complete the folding and storage of the leg frame.

[0030] The backrest frame is rotatably connected to the support frame. The backrest frame includes two backrest bars 5 that are rotatably connected to the cross bar 2 and a link assembly for connecting the two backrest bars 5. The link assembly is hinged to the two backrest bars 5. Since the backrest bars 5 are rotatably connected to the cross bar 2, the entire backrest frame can be rotated and folded for storage. Further, the link assembly includes two connecting rods 6 that are hinged to the backrest bars 5 and a connector 7 for connecting the two connecting rods 6. The connector 7 is hinged to the two connecting rods 6. Therefore, when the two fork bars 3 are rotated and folded, the two connecting rods 6 can also be rotated and folded for storage under the action of the connector 7, realizing the folding and storage of the entire backrest frame.

[0031] Refer to Figure 2 and the angle adjusting device includes a support plate 8 that is rotatably connected to the backrest frame, a clamping plate 9 provided at the bottom of the support plate 8, a clamping groove 10 provided on the clamping plate 9, and a clamping bar 12 provided in the clamping groove 10. The clamping bar 12 is used for connecting the two legs 1, and a plurality of clamping holes 11 into which the clamping bar 12 can be inserted are arranged in the clamping groove 10. The support plate 8 is rotatably connected to the backrest bar 5 of the backrest frame. Refer to Figure 3 When the angle of the backrest frame needs to be adjusted, only need to lift the support plate 8 upwards so that the clamping bar 12 disengages from the clamping hole 11 and enters the clamping groove 10, and then insert it into the corresponding clamping hole 11 to realize the adjustment of the angle of the backrest frame.

[0032] Refer to Figure 4 and Figure 5 When the entire recliner needs to be folded and stored, only need to fold and store the support frame, the backrest frame and the leg frame at the same time, so that the entire recliner can be folded to the maximum extent during storage, thus significantly reducing the space occupied by the recliner after storage and improving the space utilization efficiency.

[0033] Embodiment 2

[0034] Since it is necessary to lie up and then lift the tray 8 upward to adjust the angle of the backrest during the process of adjusting the angle of the backrest backward, in order to further improve the convenience of adjusting the angle of the backrest, referring to Figure 6 、 Figure 7 , an elastic limiting device is provided between two adjacent card holes 11. The elastic limiting device includes a clamping block 13 rotatably arranged in the card slot 10, a storage groove arranged in the clamping plate 9 for the rotation and storage of the clamping block 13, and an elastic component arranged in the storage groove. The elastic component includes an arc-shaped sliding groove 15 arranged in the storage groove, a spring 16 arranged in the arc-shaped sliding groove 15, and a sliding rod 17 connected to the clamping block 13. One end of the sliding rod 17 is connected to the clamping block 13, and the other end is connected to the spring 16.

[0035] When it is necessary to adjust the angle of the backrest backward, the user only needs to take a slight backward swing of the body or ask others for assistance to apply a backward force to the backrest. This acting force will cause the clamping rod 12 to come into contact with the clamping block 13 and apply pressure, causing the clamping block 13 to rotate against the elastic force of the spring 16 (in this embodiment, without a certain acting force provided by the backward swing, the gravity alone cannot drive the clamping block 13 to rotate, and according to the order of the card holes 11 arranged from left to right, the elastic force of the corresponding spring 16 gradually increases), and finally enter the storage cavity 14. Once the clamping block 13 enters the storage cavity 14, it will no longer limit the clamping rod 12, so that the clamping rod 12 can move freely in the card slot 10 and be smoothly clamped into another card hole 11 to realize the adjustment of the angle of the backrest. Compared with lying up and lifting the tray 8 upward for adjustment, it is more convenient to use.

[0036] The above is only a preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, and improvements made on the basis and within the scope of the present invention shall be included in the protection scope of the present invention.
