Detailed Description

Example 1:

referring to fig. 1 to 6, the novel armrest comprises an armrest body 1, a shell 2 and a fixing component.

The handrail body 1 is the handrail surface position, and the handrail body 1 is connected with the casing 2 for the handrail body 1 is the vertical lift adjustment relative to fixed subassembly. Here, the armrest body 1 and the housing 2 may slide back and forth relatively, or the armrest body 1 and the housing 2 may rotate left and right relatively, and the specific structure here is the prior art, so the description in this embodiment is omitted.

Casing 2 is upper end and handrail main part 1 and is connected fixedly promptly, and casing 2 is hollow structure, and the gear piece stretches into in casing 2, and slides from top to bottom for casing 2.

The fixing component comprises a gear piece 3, a buffer sheet 4 and a button 5.

The shift member 3 is L-shaped as a whole, and has a longitudinal position extending into the housing 2, and a fixing groove 31 and a shift groove 32 are formed in the longitudinal position.

The number of the fixing grooves 31 on the gear member 3 can be selected according to actual requirements, in this embodiment, the fixing grooves 31 form two buffer areas, one buffer area is located at the top end of the gear member 3, and the other buffer area is located at the middle end of the gear member 3. The provision of two buffer areas further improves the sliding stability of the member 3 within the housing 2. Two buffer areas are parallel arrangement, and the fixed slot 31 that is located same buffer area all is located same horizontal plane, and a plurality of buffer plates 4 make up for the slip of gear piece 3 in casing 2 is more stable, and is smooth and easy. Each fixing groove 31 is correspondingly fixed with a buffer sheet 4. It should also be noted here that the fixing groove 31 does not penetrate through the side wall of the stop element 3.

The fixing groove 31 is internally provided with a through hole 311, and the through hole 311 is used for being matched with the buffer sheet 4 to realize the fixing effect.

The gear groove 32 is used for adjusting the gear, and here the gear groove 32 is a side wall penetrating the gear 3 and communicating with the inside of the gear 3, and the inside of the gear 3 is also hollow.

The interior of the gear member 3 is hollow, and a sliding groove 33 and a reinforcing rib 34 are provided therein, the sliding groove 33 being located on the inner side of the side wall corresponding to the gear groove 32. The setting of spout 33 forms the spacing effect of direction, prevents that the elastic component from taking place the skew at the slip in-process. The reinforcing ribs 34 are connected to both sides of the inner wall of the gear member 3. The arrangement of the reinforcing ribs 34 improves the strength inside the gear piece 3.

The transverse position of the gear piece 3 is used for being connected with a chair support, and the fixing effect between the whole armrest and the chair is achieved. In this embodiment, the gear 3 is integrally formed and may be made of plastic.

The buffer sheet 4 is positioned in the fixing groove 31 and fixed. The buffer sheet 4 is provided with a fixing column 41 and an outward convex bulge 42.

Here, a fixing post 41 is provided on one of the buffer sheets 4, and the fixing post 41 is located at the center of the buffer sheet 4. The position of the fixing column 41 is limited, so that a three-point positioning effect is achieved, and the fixing strength of the buffer sheet 4 is further improved. The front end of the fixing post 41 is provided with two elastic buckling parts 411 and a through groove 412, where the number of the elastic buckling parts 411 is two, and the two elastic buckling parts 411 are located on two sides of the through groove 412, so that the elastic effect of the elastic buckling parts 411 is better and the buckling effect is better achieved through the arrangement of the through groove 412.

In this embodiment, the elastic fastening portion 411 extends into the through hole 311, and then abuts against the side wall of the through hole 311 through the elastic fastening portion 411, so as to achieve the fixing effect between the buffer sheet 4 and the gear member 3, and meanwhile, the two ends of the buffer sheet 4 abut against the side wall of the fixing groove 31, thereby forming a further fixing effect.

The bump 42 is a protrusion facing the fixing groove 31, and when the shift position member 3 is engaged with the housing 2, the bump 42 abuts against the inner wall of the housing 2 to form a buffering effect.

Further, in this embodiment, the fixing column 41 may be directly in interference fit with the through hole 311 to form a fixing effect. However, the interference fit is different from the snap-fit fixation in terms of the installation difficulty, so the snap-fit is taken as an example in the embodiment for description.

Be equipped with on the button 5 and press splenium 51 and elastic component 52, be equipped with joint arch 511 on pressing splenium 51, joint arch 511 offsets with gear groove 32, presses splenium 51 part to pass the shell and stretches out outside the shell, and elastic component 52 stretches into to the gear 3 in, the elastic component slides in spout 33.

The setting of button 5 forms the effect that the gear was adjusted, through pressing button 5 for elastic component 52 deformation, then slide button 5, when loosening button 5, joint arch 511 offsets with gear groove 32, thereby realizes the regulation effect of gear.
