New description: [New technical field] [0001] The present invention relates to a seat, in particular to a seat that can adjust the angle of the seat back. [Prior Art] [0002] The seat is a kind of furniture that is always kept at home. People can sit and relax on the top to relieve fatigue. In addition, in order to enhance their leisure function, the seat back is generally designed as an angle-adjustable structure. People can adjust the inclination of the back of the chair according to their own needs, and then fix the seat back position by the fixed structure, and use it to lean back when sitting on the rest chair. The current adjustable back angle of the market' The seat is solid; the fixed structure is mostly the elastic method of the bolt or the knob. It is necessary to rotate the pine to move slightly; the back can be adjusted in angle, and after adjusting to the required position, it is necessary to tighten and fix the seat back' It is more glazed and requires a lot of effort and is not easy to use. In addition, the seat with only the backrest adjustment function also has a single function, and the effect of rest is insufficient, which makes it difficult to bring people a better enjoyment. [New Content] [0003] The purpose of this creation is to provide a seat that is simple and reasonable in structure and that is easy to use and that can adjust the angle of the seat back. The creation includes a seat, a seat back and a handrail seat, and a base, wherein the seat back and the seat are pivotally connected together, and the two sides of the back of the chair are connected to the side of the armrest or the base of the base, and the armrest is engaged with the base. The seat is provided with a sliding rod that is coupled with the seat, and a guide seat for arranging the sliding rod is disposed on the armrest seat or the base. The guiding seat includes a control rod, a housing, and an actuating rod at least-squeezing Piece, at least - spring 'and the shell and the armrest seat or base fixed on page 3 / a total of 12 pages form number A0101 M393233, and can be inserted into the slide bar, and the actuating rod is vertically assembled on the housing, and corresponding The housing rotates 'the end of the actuating rod is connected with the control rod at one end, and a large diameter abutting portion is arranged at different angular positions on the outer edge; and the pressing member is provided with an aperture slightly larger than the diameter of the sliding rod and can be inserted and slipped. The perforation of the rod; the spring system provides the displacement of the pressing member to actuate the elastic force' and rotates the actuating rod by the control rod, and the abutting portion can abut or not abut against the pressing member, and the perforating hole of the pressing member The wall may not engage or snap with the slider to adjust the angle of the seat back. [Embodiment] [0004] Referring to the first and second figures, the present invention includes a seat 1, a seat back 2, and a handrail seat 3, wherein the armrest seat 3 is mounted on the base 10 at the lower portion of the seat to form an integral supporting and fixing structure. The seat back 2 is pivotally connected with the reading seat 1 and the two sides of the seat back 2 are pivotally connected to the rear sides of the armrest seat 3 so that the seat back 2 passes through the pivot of the armrest seat 3 itself. The joint rotates for the shaft so that the lower forward or backward movement 'allows the connected seat 1 to also move forward or backward by a certain distance. Further, the seat 1 is provided with a slide bar 12 that is interlocked with the seat 1, and the guide seat 4 is provided with a guide seat 4 for arranging the slide bar 12. Referring to the first to fourth figures, the guide seat 4 includes a control rod 41, a housing 42, an actuating rod 43, two dust members 44, two springs 45, and the housing 42 is fixed to the armrest base 3, and has a chamber 421, a through hole 422, two engaging grooves 423, and a shaft hole 424, and the through hole 422 is inserted into the sliding rod 12'. The end of the actuating rod 43 is vertically assembled on the shaft hole 424, and can rotate corresponding to the housing 42. The actuating lever 43 - the end joint portion 431 is coupled with the control rod 41 and has a larger diameter abutting portion 432 at a different angle (relative 180 °) from the outer edge; and the fourth page / total 12 page form number A0101 The two extrusion members 44 are high-hardness sheets and are disposed in the chamber 421' and the bottom portion is embedded in the joint groove 423, and the actuating rod 43 is disposed between the two extrusion members 44, and the aperture is slightly larger than the slide rod. The diameter of the 12 can be inserted into the through hole 441 of the sliding bar 12, and the corresponding actuating rod 43 is disposed at a position corresponding to the abutting portion 442; the second spring 45 is sleeved with the sliding bar 12 disposed in the chamber 421, and the two ends are respectively corresponding to the chamber 421 The inner wall and the extrusion 44 abut. Referring to the third figure, when the lock is in the locked state, the actuating lever 43 is rotated by the lever 41 and the abutting portion 432 does not abut against the abutting portion 442 of the two pressing members 44, so that the two pressing The member 44 can be offset by the elastic force of the spring 45 and the hole wall of the through hole 441 is engaged with the slide bar 12, so that the slide bar 12 cannot be displaced corresponding to the guide seat 4 and can reach the locked state. Referring to the fourth figure, in the loosened state, the actuating lever 43 is rotated by the lever 41 and the abutting portion 432 abuts against the abutting portion 442 of the two pressing members 44, so that the two pressing members 44 are formed. The hole wall of the hole 441 can be offset and not engaged with the slide bar 12, so the slide bar 2 can be displaced corresponding to the guide seat 4, and the angle of the seat back 2 can be adjusted, and can be adjusted as shown in the fifth figure. . Therefore, according to the above, the creation can have better adjustment stability and reliability, and the guide seat 4 of the creation can also be set on the base (not shown) or other seats. The foregoing examples are illustrative of the present invention and are not intended to be limiting of the present invention. Any equivalent changes in accordance with the spirit of the present invention should also fall within the scope of the present invention.
