Abstract
The utility model discloses a connecting device for a seat plate and a leg tube of a folding chair. The connecting device comprise a connecting tube, wherein a leg tube fixing part for fixedly connecting the leg tube is arranged at one end of the connecting tube; a seat plate pivoting part for pivoting the seat plate is arranged at the other end of the connecting tube; the middle part of the connecting tube is provided with an arc-shaped connecting part for connecting the leg tube fixing part with the seat plate pivoting part; and the inner side of the connecting part is provided with an accommodating groove. During folding of the folding chair, the transverse lever on a front leg tube can be accommodated in the accommodating groove, and the front leg tube is fully jointed with a back leg tube, so that the thickness of the folded chair is reduced to the maximum extent. The connecting device for the seat plate and the leg tube has the advantage of capability of fully jointing the front leg tube and the back leg tube.
Description
Technical field
The utility model relates to seat board that a kind of folding seat uses and the jockey of leg pipe.
Background technology
Chair is a kind of furniture commonly used in the daily life, is used for providing rest in family, office, restaurant or other places to people, wherein, is subjected to liking of people most with folding seat again.Folding seat has superimposed and open two states, when needing to use chair fork just open can, can superimposedly pack up when not needing to use, take up room with minimizing, thereby conveniently store, transport, have very strong practicality.
Folding seat generally includes two forelegs, two back legs, a block plate and backup plates.The medium position of the described two forelegs respectively rear positions on edge, both sides relative to described seat board is articulated, and described seat board can be overturn around the pivoting point with described foreleg; The tip position of the described two back legs respectively forward position on edge, both sides relative to described seat board is articulated, and described seat board can be overturn around the pivoting point with described back leg; Midleg is articulated with the middle and lower part of described two forelegs respectively after described two, and described foreleg and described back leg can be relatively rotated; Described backup plate is fixed between the top of described two forelegs.Be fixedly connected with a cross bar between described two front midlegs, when folding seat is opened time-out, described cross bar is connected to the below of described seat board, supports described seat board.
In the time of superimposed folding seat, described seat board is upwards turned up near described backup plate, and described back leg rotates towards the direction near described foreleg, until described back leg and described cross bar connect.
Yet, because the existence of described cross bar, described two back legs can only turn to the state that connects with described cross bar at most, described back leg and described foreleg can't fit together fully, like this, still can have certain angle between described seat board and backup plate and foreleg and the back leg, the thickness after chair is folding is still larger.
The utility model content
The utility model provides seat board that a kind of folding seat that front leg tube and back leg pipe are fitted fully uses and the jockey of leg pipe, and it has overcome the existing deficiency of background technology.The technical scheme that adopts that the utility model solves its technical problem is:
The jockey of the seat board that a kind of folding seat is used and leg pipe, it comprises tube connector, this tube connector one end is provided with the leg pipe fixed part for affixed leg pipe, the other end is provided with for the seat board articulated section that articulates seat board, its middle part is provided with for the arcuation connecting portion that connects this leg pipe fixed part and this seat board articulated section, and the inboard of this connecting portion is provided with accepting groove.
Among one preferred embodiment: this tube connector is one-body molded.
Among one preferred embodiment: this tube connector is made by metal or plastics.
Among one preferred embodiment: comprise that also one end of this adapter sleeve is housed in the leg pipe be used to the adapter sleeve that is fixed between leg pipe and this leg pipe fixed part, this leg pipe fixed part is housed in the other end of this adapter sleeve.
Among one preferred embodiment: the cross sectional shape of this leg pipe fixed part is cylindrical.
Among one preferred embodiment: this tube connector bending is V-shaped, and this accepting groove is bent to form by this tube connector
The technical program is compared with background technology, and it has following advantage:
1. this connecting portion is arcuation, its inboard is provided with accepting groove, in the time of superimposed folding seat, cross bar on the front leg tube can be housed in this accepting groove, front leg tube and back leg pipe fit together fully, just can there be any angle between seat board and backup plate and front leg tube and the back leg pipe, makes the thickness after chair folds reduce to minimum.Therefore, the jockey of seat board of the present utility model and leg pipe has advantages of can make front leg tube and back leg pipe fit fully, and it is quite convenient to deposit and transport.
In addition, because this tube connector and back leg pipe are minute body formed, therefore, this tube connector can be selected the pipe bending forming thinner than this leg pipe, so just can guarantee that the arc shape of this connecting portion is enough large, and namely the size of this accepting groove is large as far as possible.And for back leg pipe of the prior art, because its diameter is larger, can't be bent preferably, therefore can't bend out the accepting groove in the utility model.
2. this tube connector is one-body molded, has well-set advantage.
3. this tube connector is made by metal or plastics, has moulding and is easy to advantage.
4. also comprise be used to the adapter sleeve that is fixed between leg pipe and this leg pipe fixed part, so that jockey of the present utility model can be suitable for multiple chair, highly versatile.
5. the cross sectional shape of this leg pipe fixed part is cylindrical, has advantages of the material of saving.
6. this accepting groove is bent to form by this tube connector, need not other processing, therefore has advantages of convenient for production; In addition, it is larger that the size of this accepting groove can be done, to satisfy the requirement of accommodating cross bar fully.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 has illustrated the overall schematic of the folding seat of the jockey that is assembled with seat board of the present utility model and leg pipe.
The master that Fig. 2 has illustrated folding seat shown in Figure 1 looks schematic diagram.
Fig. 3 has illustrated part amplification and the decomposing schematic representation at A place among Fig. 2.
