DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A leisure chair reinforcement structure includes a chair seat 1 and a mounting groove, a driving button 2 is provided on the side wall of the chair seat 1, a chair base 4 and a first connecting groove 8 are provided on the top of the chair seat 1, a tilting mechanism is provided in the mounting groove 5, the tilting mechanism includes a rotating shaft 6 rotatably connected in the mounting groove 5, a chair back 7 is fixedly installed on the top of the rotating shaft 6, a mounting block 12 is fixedly connected to the side wall of the chair back 7, and a limited position slide groove 13 is provided in the mounting block 12;

[0022] An adjusting mechanism is provided in the first connecting groove 8, and the end of the adjusting mechanism extends into the tilting mechanism and is slidably connected therewith. The adjusting mechanism comprises an electric push rod 9 fixedly installed at the bottom of the first connecting groove 8, and the telescopic end of the electric push rod 9 is fixedly connected to a connecting rod 10, and the side wall of the connecting rod 10 is fixedly connected to a limited sliding rod 11, and the end of the limited sliding rod 11 extends into the mounting block 12 and is slidably connected to the limiting sliding groove 13. The adjusting mechanism comprises an electric push rod 9 fixedly installed at the bottom of the first connecting groove 8, and the telescopic end of the electric push rod 9 is fixedly connected to a connecting rod 10, and the side wall of the connecting rod 10 is fixedly connected to a limited sliding rod 11, and the end of the limited sliding rod 11 extends into the mounting block 12 and is slidably connected to the limiting sliding groove 13. Through the arrangement of the tilting mechanism and the adjusting mechanism, the limiting sliding rod 11 can be displaced by the driving of the electric push rod 9, and the limiting sliding rod 11 can be horizontally limited by the mounting block 12, thereby driving the chair back 7 to be tilted forward and backward, abandoning the traditional handle adjustment method, and the adjustment is convenient;

[0023] Two placement plates 3 are fixedly installed at the bottom of the chair seat 1. Both placement plates 3 are provided with disassembly and assembly mechanisms. The disassembly and assembly mechanisms include dovetail grooves provided in the placement plates 3. Dovetail blocks 14 are slidably connected in the dovetail grooves. The bottom of the dovetail blocks 14 is fixedly connected to the chair base 4.

[0024] A second connecting groove 15 is provided in each of the two placement plates 3, and a clamping mechanism is provided in each of the two second connecting grooves 15. The ends of the two clamping mechanisms extend into the relative disassembly and assembly mechanisms and are tightly pressed against the inner side walls thereof. The clamping mechanism comprises a pull plate 16 slidably connected in the second connecting groove 15, a first spring 17 is fixedly connected between the side wall of the pull plate 16 and the inner side wall of the second connecting groove 15, a clamping rod 18 is fixedly connected to the side wall of the pull plate 16, and an end of the clamping rod 18 extends into the dovetail groove and is tightly pressed against the inner side wall thereof. By setting the disassembly and assembly mechanism and the clamping mechanism, after the dovetail block 14 is inserted into the dovetail groove, it can be limited and reinforced by the blocking of the clamping rod 18, so as to prevent the chair base 4 from falling off due to excessive shaking of the chair.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] In the present invention, when the staff uses the present invention, the staff pulls the pull plate 16 and slides the chair base 4 outward to complete the disassembly of the chair base 4. When the staff needs to install the chair base 4, the staff pulls the pull plate 16, and the pull plate 16 drives the clamping rod 18 to move, so that the clamping rod 18 no longer blocks the dovetail groove in the placement plate 3, and the staff slides the dovetail block 14 and the chair base 4 into the dovetail groove. When the dovetail block 14 is installed to a suitable position, the pull on the pull plate 16 is released, and the pull plate 16 drives the clamping rod 18 to reset under the pulling force of the first spring 17, and the end of the clamping rod 18 enters the dovetail groove again, thereby blocking and limiting the dovetail block 14 to prevent the chair from shaking excessively and causing the chair to The sub-base 4 falls off; when the staff needs to adjust the front and rear tilt of the chair back 7, the staff can drive the electric push rod 9 to operate by pressing the drive button 2. The driving of the electric push rod 9 will drive the connecting rod 10 to move, and the displacement of the connecting rod 10 will drive the limit slide 11 to move up and down. When the upper limit slide 11 moves upward, the displacement of the limit slide 11 will be limited by the mounting block 12. Therefore, the mounting block 12 will be squeezed by the limit slide 11 and tilted forward, thereby driving the chair back 7 to tilt forward, and vice versa, driving the chair back 7 to tilt backward. Through the setting of the electric push rod 9 and the limiting of the mounting block 12 and the limit slide 11, the stability of the tilt angle of the chair back 7 can be guaranteed, thereby playing a role in strengthening support.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
