[0035] Referring to Figures 1-7The reclining seat with an angle adjusting mechanism is shown, which comprises a seat 1 and a backrest 2 connected in rotation, a mounting seat 3 fixedly connected with the seat 1, a connecting piece 4 arranged on the backrest 2, a mounting groove 5 arranged on the connecting piece 4, the mounting seat 3 and the mounting groove 5 being connected in rotation, a sliding groove 6 arranged on the mounting seat 3, a sliding piece 7 slidably connected in the sliding groove 6, the sliding piece 7 and the mounting seat 3 jointly abutting against an elastic piece 8, a limiting protrusion 9 arranged on the sliding piece 7, a pushing block 10 rotatably connected on the mounting seat 3, a positioning surface 11 arranged on the pushing block 10 for driving the limiting protrusion 9, a positioning protrusion 12 arranged on the sliding piece 7, the positioning protrusion 12 being capable of extending along the extension direction of the sliding groove 6, and a first positioning groove 13 and a second positioning groove 14 correspondingly arranged on the mounting groove 5; when the positioning protrusion 12 is clamped in the first positioning groove 13 or the second positioning groove 14, the backrest 2 is in a locked state; the positioning protrusion 12 and the elastic piece 8 are respectively located on both sides of the sliding piece 7, and the rebound direction of the elastic piece 8 is consistent with the extending direction of the positioning protrusion 12.

[0036] When the elastic piece 8 rebounds, the positioning protrusion 12 extends in the extension direction of the sliding groove 6 under the rebound force, so as to be clamped in the first positioning groove 13 or the second positioning groove 14, and the rebound direction of the elastic piece 8 and the extending direction of the positioning protrusion 12 are both the extension direction of the sliding groove 6.

[0037] Preferably, the number of the connecting pieces 4 on the backrest 2 is two, and the two connecting pieces 4 are respectively located at two ends of the mounting seat 3; the number of the sliding grooves 6 on the mounting seat 3 is two, and the number of the sliding pieces 7, the elastic pieces 8 and the pushing blocks 10 is two.

[0038] Referring to Figures 3-5 It is shown that the mounting groove 5 is further provided with a limiting notch 15, and the mounting seat 3 is correspondingly provided with a mounting protrusion 16, and the mounting protrusion 16 and the limiting notch 15 are movably connected; when the end of the mounting protrusion 16 and the limiting notch 15 abuts, the positioning protrusion 12 can be clamped in the first positioning groove 13 or the second positioning groove 14. After the user releases the locking state of the backrest 2, the user can determine whether the backrest 2 is rotated to the limit angle by whether the mounting protrusion 16 abuts the end of the limiting notch 15, so as to help the user quickly understand the rotation of the backrest 2, and quickly position the position of the backrest 2, greatly improving the user experience.

[0039] Preferably, the number of the mounting protrusions 16 on the mounting seat 3 is two.

[0040] Referring to Figure 3 , 4 , 6, 7, it is shown that the limiting protrusion 9 is respectively provided with a first inclined surface 17 and a second inclined surface 18 on both sides; when the pushing block 10 rotates to one side, the first inclined surface 17 can abut the positioning surface 11; when the pushing block 10 is reversed, the second inclined surface 18 can abut the positioning surface 11. Whether the user rotates the pushing block 10 to one side or reverses the pushing block 10, the backrest 2 can be unlocked, so that the pushing block 10 can be attached to the different use habits of the user, the man-machine efficiency is better, and the user uses it more conveniently.

[0041] Referring to Figures 2-7 It is shown that it further comprises a poking rod 19, the poking rod 19 comprises a rotating shaft 20, the rotating shaft 20 penetrates the mounting seat 3, the pushing block 10 is correspondingly provided with a special-shaped hole 22, and the special-shaped hole 22 and the rotating shaft 20 are clamped. The clamping of the special-shaped hole 22 and the rotating shaft 20 makes the user not produce the phenomenon of slipping between the rotating shaft 20 and the pushing block 10 when driving the rotating shaft 20, and the setting of the special-shaped hole 22 guarantees the overall stability of the rotating shaft 20 and the pushing block 10 in use.

[0042] Referring to Figures 2-7As shown, the lever 19 also includes a grip block 21, which is located at the end of the rotating shaft 20. The grip block 21 has horizontal stripes 23 along its edge to increase friction. The rotating shaft 20 passes through the mounting base 3 and has the grip block 21 at its end, allowing the user to rotate and unlock the seat 1 from both sides, facilitating adjustment of the backrest 2 angle. The horizontal stripes 23 on the grip block 21 allow the user to easily grip and rotate it, preventing slippage and making it more convenient to use.

[0043] Preferably, there are two gripping blocks 21, with the two gripping blocks 21 located at the two ends of the rotating shaft 20 respectively.

[0044] See Figure 4 , 6 As shown, the sliding plate 7 is provided with a clearance opening 24 for mounting the push block 10. The clearance opening 24 allows the push block 10 to be mounted on the sliding plate 7, effectively reducing the lever arm from the rotating shaft 20 to the limiting protrusion 9, making it easier and more convenient to rotate the push block 10.

[0045] See Figures 3-5 As shown, the inner wall of the slide groove 6 is provided with a positioning recess 25 for accommodating the push block 10, and the push block 10 is located inside the slide groove 6. The positioning recess 25 and the push block 10 are adapted to each other so that the push block 10 can be installed in the slide groove 6. When the push block 10 rotates, it can be restricted by the slide groove 6 to avoid the push block 10 from shifting or shaking during use, thus ensuring the normal use of the push block 10.

[0046] See Figures 3-6 As shown, the mounting protrusion 16 has a positioning notch 26, which communicates with the slide groove 6. The sliding piece 7 has a mounting post 27, and the limiting protrusion 9 is located above the mounting post 27. The elastic element 8 is a spring, with one end abutting against the positioning notch 26 and the other end inserted into the mounting post 27. This secure connection between the spring and the sliding piece 7 and the positioning notch 26 prevents the spring from dislodging when the sliding piece 7 slides within the slide groove 6, effectively extending the spring's service life.

[0047] The utility model discloses a backrest 2 is provided with the first positioning groove 13 and the second positioning groove 14, and the first positioning groove 13 and the second positioning groove 14 are arranged on the slide piece 7, and the slide piece 7 is arranged on the push block 10, and the push block 10 is arranged on the rotating shaft 20, and the rotating shaft 20 is arranged on the holding block 21, and the holding block 21 is arranged on the base 1, and the base 1 is arranged on the elastic piece 8, and the elastic piece 8 is arranged on the slide groove 6, and the slide groove 6 is arranged on the limiting notch 15, and the limiting notch 15 is arranged on the mounting protrusion 16, and the mounting protrusion 16 is arranged on the backrest 2.

[0048] The above only is the preferred embodiment of the utility model, and does not therefore limit the patent range of the utility model, and all equivalent structural transformations made in the utility model specification and the attached drawing contents, or direct / indirect application in other related technical fields under the utility model concept of the utility model are included in the patent protection range of the utility model.
