A kind of Chair structure of improvement, comprise a seat support and a support, seat support is fixedly connected on the upside of support, support comprises a crossbeam, axis separately along crossbeam in the two ends end face of crossbeam is provided with a protuberance, any one protuberance is all in cylindricality, a circumferential groove is provided with in the sidewall of any one protuberance, have at least on a protuberance and be arranged with a connector, be provided with a hole in the two ends end face of connector separately, the radial cross-sectional shape in hole coordinates with the radial cross-sectional shape of protuberance.The utility model arranges protuberance at the two ends of the crossbeam of chair, utilize connector to coordinate with protuberance, thus connect the crossbeam of two adjacent chairs of left and right, multiple independently chair is connected in a row, elastic collar coordinates with the circumferential groove of protuberance, can prevent accidental separation between chair.Utilize external force connector can be removed from crossbeam, thus by the adjustment of required seat number.
Description
Technical field:
The utility model relates to mankind life article, particularly relates to furniture, the chair of particularly classroom, Conference Hall use, the Chair structure of particularly a kind of improvement.
Background technology:
The chair set in a row is often used in classroom, Conference Hall.In prior art, this kind of chair set in a row just forms fixing syndeton when producing or install, and is using on-the-spot cannot by required seat number adjustment, thus often causing taking too much space.
Summary of the invention:
The purpose of this utility model is the Chair structure providing a kind of improvement, and the Chair structure of described this improvement will solve the chair set in a row in prior art and use the on-the-spot technical problem that cannot adjust by required seat number.
The Chair structure of this improvement of the present utility model comprises chair, described chair comprises a seat support and a support, described seat support is fixedly connected on the upside of described support, support comprises a crossbeam, wherein, axis separately along crossbeam in the two ends end face of described crossbeam is provided with a protuberance, protuberance described in any one is all in cylindricality, a circumferential groove is provided with in the sidewall of any one protuberance, have at least on a protuberance and be arranged with a connector, a hole is provided with separately in the two ends end face of described connector, the radial cross-sectional shape in described hole coordinates with the radial cross-sectional shape of protuberance.
Further, crossbeam is cylindrical, and the protuberance described in any one is all cylindrical, and connector is cylindrical.
Further, in the inwall of hole, be provided with a groove separately, in groove, be provided with an elastic collar.
Operation principle of the present utility model is: connector connects the crossbeam of two adjacent chairs of left and right, and connected in a row by multiple independently chair, elastic collar coordinates with the circumferential groove of protuberance, can prevent accidental separation between chair.Utilize external force connector can be removed from crossbeam, thus by the adjustment of required seat number.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model arranges protuberance at the two ends of the crossbeam of chair, utilize connector to coordinate with protuberance, thus connect the crossbeam of two adjacent chairs of left and right, multiple independently chair is connected in a row, elastic collar coordinates with the circumferential groove of protuberance, can prevent accidental separation between chair.Utilize external force connector can be removed from crossbeam, thus by the adjustment of required seat number.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the Chair structure of improvement of the present utility model.
Detailed description of the invention:
Embodiment 1:
As shown in Figure 1, the Chair structure of improvement of the present utility model, comprise chair, described chair comprises a seat support 1 and a support 2, described seat support 1 is fixedly connected on the upside of described support 2, support 2 comprises a crossbeam 21, wherein, axis separately along crossbeam 21 in the two ends end face of described crossbeam 21 is provided with a protuberance 22, protuberance 22 described in any one is all in cylindricality, a circumferential groove is provided with in the sidewall of any one protuberance 22, have at least on a protuberance 22 and be arranged with a connector 3, a hole is provided with separately in the two ends end face of described connector 3, the radial cross-sectional shape in described hole coordinates with the radial cross-sectional shape of protuberance 22.
Further, crossbeam 21 is cylindrical, and the protuberance 22 described in any one is all cylindrical, and connector 3 is cylindrical.
Further, in the inwall of hole, be provided with a groove separately, in groove, be provided with an elastic collar.
The operation principle of the present embodiment is: connector 3 connects the crossbeam 21 of two adjacent chairs of left and right, and connected in a row by multiple independently chair, elastic collar coordinates with the circumferential groove of protuberance 22, can prevent accidental separation between chair.Utilize external force connector 3 can be removed from crossbeam 21, thus by the adjustment of required seat number.
