Abstract

The utility model provides a chair framework belonging to the field of articles for home life. The chair framework comprises a backrest and handrails, wherein the backrest is provided with connection parts; the handrails are provided with inserting parts matched with the connection parts; the backrest and the handrails are connected in an inserting manner. According to the chair framework, the backrest and the handrails are connected in the inserting manner and a previous structure that the backrest and the handrails are fixedly connected by screws is avoided, so that the screws and an assembling manner cannot be seen from the outer side; the inserting structure is simple and convenient and is firm to assemble.

Description

A kind of Chair frame

Technical field

The utility model relates to furniture daily necessities, is used in particular for the skeleton of chair.

Background technology

The chair that has in the market many types, client is also ever-changing to the requirement of chair.Along with the intensification day by day of the Internet culture, client, to the thing buying oneself assembling, becomes a new difficult problem.The design direction of a lot of chairs is more to simplify in syndeton.Simple syndeton had both meaned simple in structure, assembled simplyr, and that just can reduce production cost, enhances productivity.

Utility model content

The purpose of this utility model, is to solve the problems of the technologies described above, and provides a kind of simple in structure, easy to assembly, and can't see from the outside the Chair frame of screw.

Technical solution of the present utility model is: comprise backrest, handrail, described backrest arranges connecting portion, the Plug Division that described handrail setting and connecting portion are connected, and described backrest is connected by inserting mode with handrail.

The structure patching by backrest and armrest straight, just can make the simpler of whole assembling change, and chair outer surface also be can't see screw, makes product more attractive in appearance.

As preferably, the connecting portion of described backrest comprises contiguous block, offers transverse groove, panel slot, cannelure and bottom surface groove on contiguous block; Described transverse groove is used for preventing that handrail from moving left and right, and cannelure is used for preventing that handrail from moving forward and backward.

As preferably, the Plug Division of described handrail comprises grafting piece, and described grafting piece comprises base plate, lateral projection, armrest surface sheet frame and longitudinal projection; Described lateral projection and transverse groove are connected, and described longitudinal projection and cannelure are connected, and described base plate and bottom surface groove are connected.

As further preferred, described lateral projection one end is connected with base plate, and the other end arranges tip angle.

As further preferred, in described contiguous block, the width of transverse groove and cannelure dwindles from the bottom up.

As preferably, on the base plate of described grafting piece, offer screwed hole, on the contiguous block of described backrest, also offer corresponding hole.

The utility model beneficial effect is: backrest was connected inserting mode with armrest straight and is connected, the structure that has needed screw to be fixedly connected with between that backrest and handrail before having avoided, can't see so from the outside screw and also can't see assembling mode, and this connected structure is simple and convenient, assembling firmly.

The specific embodiment

Below in conjunction with accompanying drawing, with embodiment, the utility model is described in further detail.

Embodiment 1, as Figure 1-4, and a kind of Chair frame, comprise backrest 1 and handrail 2, backrest 1 is connected and is surrounded by four supports, 3 head and the tail, and wherein connecting portion 11 is offered in the bottom of two supports 3 in left and right of backrest 1, and the length of described connecting portion 11 accounts for greatly 1/3rd of support 3 length.Handrail 2 is the corresponding Plug Division 21 of having offered also.The grafting that matches of connecting portion 11 and Plug Division 21, grafting direction is from the bottom up.Handrail 2 grafting that moves up from the bottom of backrest 1.Connecting portion 11 comprises contiguous block 12.Contiguous block 12 is that one is connected with support 3.Contiguous block 12 comprises transverse groove 13, panel slot 14, cannelure 15 and bottom surface groove 16; Described transverse groove 13 moves left and right for preventing handrail 2, and cannelure 15 moves for preventing handrail 2 fore-and-aft directions.The direction that handrail 2 is taken towards user be the place ahead to, otherwise be rear to.

The Plug Division 21 of handrail 2 comprises grafting piece 22, and grafting piece 22 comprises base plate 23, lateral projection 24, armrest surface sheet frame 25 and longitudinal projection 26; Described lateral projection 24 is connected with transverse groove 13, and described longitudinal protruding 26 are connected with cannelure 15, and described base plate 23 is connected with bottom surface groove 16.Between lateral projection 24, armrest surface sheet frame 25 and longitudinal projection 26, be all integrated connection, be then fixed on base plate 23.As seen in Fig. 4, the front end that lateral projection 24 is inserted backrest 1 transverse groove 13 arranges tip angle 241, can conveniently insert like this.

In order to prevent departing between handrail and backrest, it is mainly the disengaging of above-below direction, so the transverse groove 13 in contiguous block 12 and the width of cannelure 15 dwindle from the bottom up, and the width of lateral projection 24 and longitudinally projection 26 is constant, can pass through interference fit between the two like this, what make that backrest 1 is connected with handrail 2 is more firm, can not depart from easily.In order to strengthen the connection between backrest 1 and handrail 2, can also on the base plate 23 of grafting piece 22, offer screwed hole 211, this screwed hole 211 preferably also has an inner groovy in outside, for built-in nut.Outside is just difficult to see the bolt of the inside like this.Corresponding, on contiguous block 12, also to offer corresponding hole 122.
