Abstract

The utility model relates to an angle sheathing type sheathing connection structure for connecting a chair seat and a chair frame of a soft surface folding chair, which has the advantage that the chair seat can be conveniently installed and dismounted. The utility model is characterized in that two connected side edges with a certain angle to each other form a shape with the small upper part and the large lower part, i.e. a chair frame sheathing connection structure is formed by a left bearing connection rod and a right bearing connection rod which are mutually connected, have the certain angle to each other and are connected with the chair frame. The left and right sheathing connection positions with the proper shape and size of the connected chair seat with an opening at one side is sheathed and connected with the chair seat sheathing connection structure with the same included angle as the left bearing connection rod and the right bearing connection rod of the chair frame. After the sheathing connection, the chair seat can not surpass the virtual bottom edge of the included angle of the sheathing connection part of the chair frame, so the chair seat is limited on the chair frame, the chair seat can be easily taken down from the chair frame through the top of the included angle of the chair frame part, and the goal of conveniently installing/dismounting the chair seat on/from the chair frame can be reached.

Description

The socket join structure that a kind of seat of soft folding seat is connected with the chair frame

Affiliated technical field

The utility model relates to two with soft seat and be connected soft folding seat of a class on the chair frame, refer to the socket join structure that seat is connected with the chair frame especially.

Background technology

Soft folding seat of prior art is connected socket join structure on the chair frame with seat, general all is that the position that the chair frame connects seat is made into cross bar, the position that then soft seat is connected the chair frame is sewn into horizontal running-on, is socketed on the cross bar of chair frame, makes seat be fixed on (Fig. 1) on the chair frame.This technical matters complexity, processing are loaded down with trivial details, and seat be difficult for to be changed and clean.In case seat breakage, folding seat are discarded the chair frame together because of seat is difficult for changing, and have the waste of resource.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of soft folding seat is easy for installation and removal cover angie type socket join structure that the seat of seat is connected with the chair frame.

The technology side that its technical problem that solves the utility model adopts is by being: the position that the chair frame is connected seat in the process of making the chair frame is made into the shape that up-small and down-big dual-side is mutually angle, its dual-side that is mutually angle is used as the left and right bearing rod of chair frame socket join structure; Then with the position of seat socket chair frame according to this shape be sewn into the sizeable running-on of an opening, the mutual formed angle angle in its left socket position and right socket position equates with chair frame belled position left side bearing rod and the mutual formed angle angle of right bearing rod, so that make it can snugly be linked in the socket place of chair frame belled position, as mechanical taper fit positioning principle, the belled position of seat can not surmount the virtual base of chair frame belled position angle and seat is limited on the chair frame, be very easy to and seat taken off from the chair frame, reach the purpose that seat is easy for installation and removal on the chair frame from the top of chair frame belled position angle.

The beneficial effects of the utility model are: the seat of soft folding seat is mounted and dismounted on the chair frame become very easy.If standardized production, seat be production and selling separately,, can there be the waste of resource even seat breakage, folding seat also can not be difficult for changing with the chair frame discarded together because of seat.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structure chart of the socket join structure of soft folding seat of prior art.

Fig. 2 is the structure chart of the utility model seat belled position.

Fig. 3 is the structure chart of the utility model chair frame belled position.

Fig. 4 is the structure chart after the belled position socket of the utility model seat and chair frame.

1. chair framves among the figure, 2. seat, 3. the opening of seat socket join structure, the 4. connecting rod of chair frame socket join structure, 4 '. the top of seat socket join structure, 5. the left bearing rod of chair frame socket join structure, 6. the right bearing rod of chair frame socket join structure, 5 '. the left socket position of seat socket join structure, 6 '. the right socket position of seat socket join structure, 7. the angle of chair frame socket join structure, 7 '. the angle of seat socket join structure.

The specific embodiment

At Fig. 2, among Fig. 3 and Fig. 4, angle (7) angle of the left bearing rod (5) of chair frame (1) socket join structure and right bearing rod (6) equates with angle (7 ') angle of the left socket position (5 ') of seat (2) socket join structure and right socket position (6 '), thereby the connecting rod (4) of chair frame (1) socket join structure, left side bearing rod (5), right bearing rod (6) is by the opening (3) of seat (2) socket join structure, after making the socket join structure fit of seat (2) socket join structure and chair frame (1), the left socket position (5 ') of seat socket join structure is linked in (Fig. 4) with what the right socket position (6 ') of the left bearing rod (5) of chair frame socket join structure and seat socket join structure and the right bearing rod (6) of chair frame socket join structure can be fitted.The socket join structure of seat can not surmount the socket join structure of chair frame and seat is limited on the chair frame to (E) direction after the socket, and takes off very convenient from the chair frame seat to the direction of (F).

Claims

1. the cover angie type socket join structure that is connected with the chair frame of the seat of a soft folding seat, it is characterized in that: the position that the chair frame of the chair frame of will ining succession in the process of making the chair frame is connected with seat is made into the shape that up-small and down-big dual-side is mutually angle, its dual-side that is mutually angle is used as the left and right bearing rod of chair frame socket join structure, with its socket join structure as the chair frame; To in succession the then position of seat socket chair frame of seat is sewn into the shape that up-small and down-big dual-side is mutually the sizeable running-on of the opening that the angle angle of angle equates with chair frame belled position left side bearing rod and the mutual formed angle angle of right bearing rod equally, a left side of its dual-side that is mutually angle being used as seat, right socket position, with its socket join structure as seat, because the size to fit of seat socket join structure and chair frame socket join structure, the mutual formed angle angle in the left socket position of seat socket join structure and right socket position equates with the left bearing rod and the mutual formed angle angle of right bearing rod of chair frame socket join structure, just make the seat socket join structure can snugly be linked in the socket place of chair frame socket join structure, as mechanical taper fit positioning principle, the belled position of seat can not surmount the virtual base of chair frame belled position angle and seat is limited on the chair frame, and takes off seat very easy from the chair frame from the top of chair frame belled position angle.
