The positioning cylinder at the side end of the locking button is positioned, and a concave hole is provided on the bottom surface of the horizontal end of the L-shaped bracket, and a spring and a locking button are accommodated, and the sliding passage is set in a bracket seat; the bracket seat is a rectangle Hollow seat body, with fixed ears on the periphery, integrally screwed on the bottom of a cushion, a guide groove structure composed of symmetrical clamping round holes and slide grooves is pierced in the center of the bottom surface; The guide groove structure passing through the bracket seat is screwed to the positioning cylinder at the bottom of the lower clamping button, so that the positioning cylinder of the lower clamping button is embedded and fixed in the clamping round hole, and the convex column of the lower adjusting button slides in the horizontal adjustment In the guide groove structure of the bracket seat, the L-shaped bracket and the handrail are shifted left and right.

The above-mentioned design mainly utilizes the L-shaped bracket to be slidably assembled between the armrest seat and the bracket seat, and the vertical and lateral positions of the armrest can be adjusted in multiple stages by pressing an up and down adjustment button respectively to achieve the effect of adjusting the armrest of the seat.

Further description will be given below by accompanying drawings and embodiments.

As shown in Figures 1-6: the utility model is composed of an armrest seat 10, an upper adjustment button 20, an L-shaped bracket 30, a bracket seat 40 and a lower adjustment button 50; A handrail 11 is screwed on the top surface, and two circular holes 13, 16 are correspondingly pierced in the center of both sides respectively, and two retaining edges 14, 17 are respectively arranged around the bottom edges of the corresponding circular holes 13, 16, and the positioning one upper adjustment button 20 is passed through. ; The side end of the upper adjustment button 20 is connected with a protruding post 21, and a spring 22 is slidably positioned in the corresponding round holes 13 and 16. One end of the spring 22 is pushed against the retaining edge 14 in the round hole 13, and the other round hole 16 is provided with an upper clamping button 26, and the upper clamping button 26 and the upper adjustment button 20 pass through an L-shaped bracket 30 oppositely, so as to be screwed into a sliding positioning adjustment structure; the vertical end of the L-shaped bracket 30 slides through and is positioned on the In the armrest seat 10, the center of the vertical end is a guide groove structure composed of a symmetrical clamping round hole 32 and a chute 31. The circular hole 32 is clamped to position the positioning cylinder 27 at the side end of the clamping button 26, and the bottom surface of the horizontal end of the L-shaped bracket 30 A concave hole 38 is recessed, and accommodates a spring 58 and a fastening button 56, and slides through and is located in a bracket seat 40; the bracket seat 40 is a rectangular hollow seat body, and the periphery has fixed ears 46 integrally screwed. At the bottom of the seat pad 60, a guide groove structure consisting of a symmetrical clamping hole 42 and a chute 41 is formed in the center of the bottom surface; The guide groove structure is screwed to the positioning cylinder 57 at the bottom of the lower clamping button 56, so that the positioning cylinder 57 of the lower clamping button 56 is embedded in the clamping round hole 42, and the protrusion 51 of the lower adjusting button 50 is horizontally adjusted. Sliding in the guide groove structure of the bracket seat 40, the L-shaped bracket 30 and the armrest 11 are shifted left and right. Wherein, the diameter of the positioning cylinder 27 connected to the side end of the upper clamping button 26 is larger than the diameter of the protrusion 21 of the upper adjustment button 20, so that the end edge of the upper clamping button 26 can be subjected to elastic force to push against the stopper positioned in the circular hole 16. edge17. Wherein, the diameter of the positioning cylinder 57 at the bottom of the lower clamping button 56 is larger than the diameter of the protrusion 51 of the lower adjusting button 50 . And the protruding post 51 can slide in the guide groove structure of the bracket seat 40 under the pressing action.

As shown in Figures 7 and 8: the armrest adjustment structure can make the armrest 11 adjust its position up and down and left and right, so that the user's body shape meets the requirements of ergonomic design, making the seat comfortable, helping to eliminate fatigue, and truly achieving rest or improving office work. efficiency effect.
