[0024] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model, and the present utility model is not limited to the following embodiments.

[0025] As Figures 1 to 5 shown, this embodiment discloses a chair with an expansion member, including a chair frame 1, a chair seat 2 and a chair back 3. The chair seat 2 is horizontally installed on the top of the chair frame 1. A support frame 11 extends upward from the rear end of the chair frame 1. The chair back 3 is installed on the upper part of the support frame 11. A handrail frame 12 extends horizontally forward from the front side of the support frame 11. The extending end of the handrail frame 12 bends downward and is connected to the front end of the chair frame 1 to form a support. An expansion connector 4 is sleeved at the connection between the support frame 11 and the handrail frame 12. One end of the expansion connector 4 is snap-connected with an expansion joint 5. The expansion joint 5 is provided with a plurality of card slots 50 for snap-connecting an article bracket 6. Preferably, the article bracket 6 can be a cup holder, an umbrella holder or a pen holder, etc., which are components for storing or hanging articles. The expansion joint 5 can snap-connect a plurality of different article brackets 6 to improve functionality and practicality. To improve the stability of the expansion connector 4, the expansion connector 4 includes two relatively cooperating connection seats 41. The inner sides of the two connection seats 41 are provided with clamping grooves 40 corresponding to the outer contour of the support frame 11. After the two groups of clamping grooves 40 cooperate relatively, a through hole for the support frame 11 to pass through is formed. After the two connection seats 41 cooperate, they are clamped and fixed on the support frame 11. On the opposite sides of the two connection seats 41, there is also a snap connection structure 42 that cooperates with each other.

[0026] Further, the clamping structure 42 includes clamping seats 421 disposed on one of the connecting seats 41 and on both sides of the clamping groove 40, and clamping grooves 422 disposed on the other connecting seat 41 and on both sides of the clamping groove 40. Preferably, the clamping seats 421 protrude from the end face of the connecting seat 41, and sliding grooves 423 are further provided on the clamping seats 421. The clamping grooves 422 are recessed from the end face of the connecting seat 41, and protruding strips 424 that cooperate with the sliding grooves 423 are further provided on the clamping grooves 422. One of the connecting seats 41 is slid down from top to bottom through the clamping groove 422 and fitted into the clamping seat 421 of the other connecting seat 41.

[0027] Further, in order to improve the supporting effect of the expansion connector 4 and prevent the hanging items from slipping, a pressing port 43 is provided at the lower part of the connecting seat 41 on the side close to the armrest 12. When the expansion connector 4 is sleeved on the support frame 11, it abuts against the top of the armrest 12 through the pressing port 43. Preferably, in order to improve the aesthetics, the contour of the pressing port 43 corresponds to the contour of the top of the armrest 12, and a lip structure 431 is provided at the edge of the pressing port 43. Preferably, the clamping seat 421 is disposed on the connecting seat 41 provided with the pressing port 43, which facilitates the downward pressing of the other connecting seat 41 when the connecting seat 41 abuts against the armrest 12 so as to be clamped onto the clamping seat 421, and the structure is more reasonable.

[0028] Further, a clamping block 411 for clamping the expansion joint 5 is provided on the connecting seat 41 on the side far from the armrest 12. The clamping block 411 protrudes from the connecting seat 41, and the width of the clamping block 411 gradually extends to both sides from the inside to the outside to form a dovetail structure. Preferably, the clamping block 411 and the connecting seat 41 are integrally formed. A connecting groove 51 for fitting on the clamping block 411 is provided on the expansion joint 5. In order to cooperate with the clamping block 411, the width of the connecting groove 51 gradually converges from the inside to the outside to form a dovetail groove structure. At the same time, a blocking block 511 for abutting against the top of the clamping block 411 is provided at the top of the connecting groove 51. The blocking block 511 and the expansion joint 5 are integrally formed. The expansion joint 5 is sleeved on the clamping block 411 from top to bottom through the connecting groove 51 and is supported by the blocking block 511.

[0029] Further, in order to prevent the expansion connector 4 from shaking during use, a fixing hole 412 penetrating the connecting seat 41 inward is provided on the clamping block 411. The expansion connector 4 is completely fixed on the support frame 11 by passing a bolt through the fixing hole 412 and fixedly connecting it to the support frame 11.

[0030] In this embodiment, as Figure 6As shown, the extension joint 5 can be selectively provided with at least one pair of clamping grooves 50 as required. When there is one pair of clamping grooves 50, the two clamping grooves 50 are symmetrically arranged on both sides of the extension joint 5. When there are multiple pairs of clamping grooves 50, the extension joint 5 extends a certain length towards one end, and the multiple pairs of clamping grooves 50 are arranged in sequence along the extension direction of the extension joint 5. By replacing the extension joint 5 with different numbers of clamping grooves 50 to clamp various different article brackets 6, the diversity of functions can be achieved.

[0031] The above content described in this specification is only an example of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the specific embodiments described or use similar methods for substitution, as long as they do not deviate from the content of this specification of the present utility model or exceed the scope defined by this claims, they should fall within the protection scope of the present utility model.
