Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of outdoor seats, in particular to an outdoor seat with multi-angle adjustment. Background Art
[0002] The backrest of the traditional outdoor seat can be adjusted, but it is adjusted and locked by the clamping block at the hinge joint of the seat backrest and the seat. When people lean back, the pressure of the upper body weight on the seat backrest multiplied by the moment will generate a large torsional force. Due to the short moment of the clamping block at the hinge joint of the seat backrest and the seat caused by the structural reason, the pressure will be very concentrated, which will cause the clamping block at the hinge joint of the seat backrest and the seat to break after bearing a large weight or long-term use. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is: in order to overcome the problems existing above, an outdoor seat with multi-angle adjustment is provided, which solves the above problems.
[0004] The utility model solves its technical problems by adopting the following technical solutions:
[0005] An outdoor seat with multi-angle adjustment includes a seat and a seat backrest whose lower end is hinged to the rear side of the seat. The seat backrest can rotate around the hinge axis. Armrests are fixedly arranged on both sides of the seat, and adjustment rails are fixedly arranged on the armrests. A spring pressing locking block is slidably arranged in the adjustment rails. The outdoor seat also includes two symmetrically arranged pull ropes. One end of each pull rope is fixed to the upper end of the seat backrest, and the other end is fixed to the spring pressing locking block.
[0006] Preferably, an opening groove facing the outer side is arranged in the adjustment rail, and clamping teeth are symmetrically and spacedly fixed on the inner side wall of the adjustment rail.
[0007] Preferably, a spring and a pressing handle pressing on the spring are arranged in the spring pressing locking block. Clamping blocks that can extend out of the spring pressing locking block are fixedly arranged on both sides of the pressing handle. When the pressing handle is not pressed, the spring jacks up the pressing handle so that the clamping blocks are stuck in the bayonet between two adjacent clamping teeth. In this way, the spring pressing locking block is set not to move back and forth. When the pressing handle is pressed, the clamping blocks drop out of the bayonet between the clamping teeth, facilitating the back-and-forth movement of the spring pressing locking block.
[0008] Preferably, outwardly protruding sliders are symmetrically arranged on the outer side wall of the spring pressing locking block, and sliding grooves for the sliders to be stuck in and slide back and forth are arranged in the adjustment rail.
[0009] Preferably, the adjustment rail is fixed to the armrest by screws.
[0010] Preferably, the drawstring has no elasticity.
[0011] The advantages and positive effects of the present utility model are as follows: The upper end of the seat backrest is tractioned by a drawstring to the adjustment rail, and the lower end of the seat backrest is fixed to the seat through a hinge shaft, effectively simplifying the connection position structure between the seat backrest and the seat, and the drawstring is connected to the upper end of the seat backrest with a longer moment arm, which can achieve a better traction stability effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0014] Figure 2 is a schematic structural view of the present utility model;
[0015] Figure 3 is Figure 1 an enlarged schematic structural view of the adjustment rail 14 in
[0016] Figure 4 is Figure 3 an internal schematic structural view of the spring pressing locking block 15 in DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The present utility model will now be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.
[0018] The following further details the embodiments of the present utility model with reference to the drawings:
[0019] As Figures 1-4 shown, an outdoor seat with multi-angle adjustment according to the present utility model includes a seat 10 and a seat backrest 11 hinged at the lower end to the rear side of the seat 10. The seat backrest 11 can rotate with the hinge shaft as the axis of rotation. Armrests 13 are fixedly provided on both sides of the seat 10, and an adjustment rail 14 is fixedly provided on the armrests 13. A spring pressing locking block 15 is slidably provided in the adjustment rail 14. The seat backrest further includes two drawstrings 12 symmetrically arranged on the left and right. One end of each drawstring 12 is fixed to the upper end of the seat backrest 11, and the other end is fixed to the spring pressing locking block 15.
[0020] Preferably, an opening groove facing the outer side is provided in the adjustment rail 14, and teeth 20 are symmetrically and spacedly fixed on the inner side wall of the adjustment rail 14.
[0021] Preferably, a spring 17 and a pressing handle 16 pressing on the spring 17 are provided inside the spring pressing and locking block 15. Clamping blocks 19 that can extend out of the spring pressing and locking block 15 are fixedly provided on both sides of the pressing handle 16. When the pressing handle 16 is not pressed, the spring 17 jacks up the pressing handle 16 so that the clamping blocks 19 are clamped into the bayonet between two adjacent cogs 20, so that the spring pressing and locking block 15 is set to be unable to move back and forth. After the pressing handle 16 is pressed, the clamping blocks 19 descend and disengage from the bayonet between the cogs 20, facilitating the back-and-forth movement of the spring pressing and locking block 15.
[0022] Preferably, sliding blocks 18 protruding outwards are symmetrically provided on the outer side wall of the spring pressing and locking block 15, and a sliding groove for the sliding blocks 18 to be clamped into and slide back and forth is provided in the adjusting rail 14.
[0023] Preferably, the adjusting rail 14 is fixed to the armrest 13 by screws.
[0024] Preferably, the pulling rope 12 has no elasticity.
