Abstract
The utility model relates to the technical field of furniture, in particular to a chair back connector, which is a hollow tube-shaped connecting part for connecting two sections of frames of a chair back together, and the surface of the connector is provided with threaded holes which are respectively close to the upper and the lower ends and are connected with the screw threads of the frames of the chair back through screws. When the connector needs to be used, connecting holes which correspond to the threaded holes are prearranged on the frames of the chair back, both ends of the connector are respectively inserted in the metal tubes of the two neighboring sections of frames of the chair back at the same sides, the threaded ends of the screws pass through the connecting holes and are screwed in the threaded holes, and thereby the frames of the chair back and the connector are locked together. The two sections of frames of the chair back can be conveniently assembled and disassembled, and the utility model has the advantages of convenient use, simple structure, convenient processing and low cost.
Description
Technical field:
The utility model relates to the furniture technical field, relates in particular to a kind of chair back connector.
Background technology:
Metallic chair is flexible and changeable with its moulding, environmental protection, good looking appearance and robust advantage more and more are subjected to people's favor, in the making of metallic chair, seat back frame is surrounded by metal tube, it typically is the metal tube welding fabrication, in most metallic chair, backing cushion is installed on seat back frame, backing cushion is made of cloth, skin or elastic webbing.In the design of existing metallic chair seat back frame, seat back frame is an integral structure, can not split, and can only pack with the maximum length of seat back frame when packing, Package size is bigger, so people are in the structure of seeking conveniently seat back frame to be split and to install.
The utility model content:
The purpose of this utility model be exactly the deficiency that exists at prior art and provide a kind of can be conveniently with seat back frame fractionation and installation, chair back connector easy to use, simple in structure, easy to process, lower-cost.
To achieve these goals, the technical solution adopted in the utility model is:
Chair back connector, its open circles tubulose connector for two joint chair back frameworks are linked together, connector near the upper end be used for the screwed hole of fixedlying connected with chair back framework screw thread near offering respectively on the surface of lower end by screw.
Offer the strip hole that extends to the centre respectively by two ends up and down on the surface of described connector.
Described connector is the hollow thin-wall tubular construction.
The utility model beneficial effect is:
The open circles tubulose connector of the utility model for two joint chair back frameworks are linked together, connector near the upper end be used for the screwed hole of fixedlying connected with chair back framework screw thread near offering respectively on the surface of lower end by screw, during use, on chair back framework, offer the connecting hole corresponding in advance with screwed hole, the two ends of connector are located in respectively in the metal tube of adjacent two joint chair back framework the same sides, then the end of thread of screw being passed connecting hole is threaded with screwed hole, and with chair back framework and connector fixing and locking, can easily two joint chair back frameworks be installed and split, easy to use, and simple in structure, easy to process, cost is lower.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation at another visual angle of the utility model;
Fig. 3 is the structural representation that the utility model is connected with chair back framework.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1～3, chair back connector, its open circles tubulose connector 1 for two joint chair back frameworks 3 are linked together, connector 1 near the upper end be used for the screwed hole 11 of fixedlying connected with chair back framework 3 screw threads near offering respectively on the surface of lower end by screw 2.Connector 1 is the hollow thin-wall tubular construction, and screwed hole 11 in the above is tapping directly, and directly punch forming of strip hole 12 is easy to process, saves cost.
Because existing backing cushion much all is made of many elastic webbings that vertically are evenly arranged in 3 of chair back frameworks, the anchor tip 5 at elastic webbing two ends is fixed on the both sides of chair back framework 3 by fixed screw 4, fixed screw 4 can pierce in the metal tube of chair back framework 3 and connector 1 is caused interference, therefore the utility model offers on the surface of connector 1 by two ends are respectively to the strip hole 12 of centre extension up and down, and strip hole 12 can be avoided fixed screw 4 during installation.
The utility model in use, on chair back framework 3, offer the connecting hole corresponding in advance with screwed hole 11, the two ends of connector 1 are located in respectively in the metal tube of adjacent two joint chair back frameworks 3 the same sides, then the end of thread of screw 2 is passed connecting hole and be threaded, and, can easily two joint chair back frameworks 3 be installed and split chair back framework 3 and connector 1 fixing and locking with screwed hole 11, easy to use, and simple in structure, easy to process, cost is lower.
Use the chair back mounting or dismounting of the utility model connector convenient, when packing, can easily seat back frame be split into more piece framework 3 and pack, reduce Package size, save packaging space, convenient transportation reduces cost of transportation.
Certainly, the above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
