Description
Technical field:
The present invention relates to the furniture part technical field, refer in particular to a kind of Cloth crossing tube that chair is used of making.
Background technology:
As shown in Figure 1, the Cloth crossing tube (10) that existing system chair is used comprises one section circular arc tube wall (11), connected two parallel straight pipe wall A (12), straight pipe wall B (13) and with straight pipe wall A (12), straight pipe wall B (13) straight pipe wall C connected vertically (14); Straight pipe wall C (14) is provided with breach (14a), and the edge that straight pipe wall C (14) locates at breach (14a) is slick and sly shape; Near breach (14a), between straight pipe wall A (12) and straight pipe wall B (13), be connected a partition wall (15), make partition wall (15), partition wall (15) and the last tube wall A (12) that is connected with straight pipe wall C (14), straight pipe wall B (13) part and straight pipe wall C (14) and go up breach (14a) formation one cavity volume (10a); Be provided with reinforcement wall (16) in the circular arc tube wall (11).
The caliber of one plastic round tube is bigger than breach (14a) width, after a this plastic round tube is respectively wrapped up at cloth two, a cloth that is enclosed with plastic round tube is made, Cloth crossing tube (10) is made the arc that adapts to the chair back and seat cushion, be located in after plastic round tube is tightened together with its cloth of parcel in the cavity volume (10a) of two corresponding Cloth crossing tubes (10), just become the chair back and seat cushion.Two corresponding Cloth crossing tubes (10) are packed on the chair frame, have promptly made chair.The chair of this structure is widely used in family, the office.
This Cloth crossing tube generally adopts uses the aluminium extrusion molding, and the chair frame is higher for intensity, does not generally adopt aluminium, and adopts iron material, and Cloth crossing tube can not adopt welding with the affixed of chair frame, can only adopt to be spirally connected or to rivet.But adopt the welding meeting more convenient sometimes.
Because the aluminum price is higher, causes the cost of making this chair higher.
Breach (14a) is though locate slick and sly shape, and cloth tension intensity herein is still too concentrated, the defective that causes cloth easily to gall.
Summary of the invention:
Purpose of the present invention just provides a kind of novel Cloth crossing tube, to overcome above-mentioned shortcoming.
The present invention is achieved through the following technical solutions: Cloth crossing tube, it comprises one section circular arc tube wall, connected two parallel straight pipe wall A, straight pipe wall B and with straight pipe wall A, straight pipe wall B straight pipe wall C connected vertically; Straight pipe wall C is provided with breach, straight pipe wall C is slick and sly shape at the edge of indentation, there, it is characterized in that: straight pipe wall C vertically extends a convergence part respectively downwards in indentation, there, and two convergence parts are connected with the both sides of arc tube wall opening respectively, and the internal diameter of circular arc tube wall is greater than the width of breach; This Cloth crossing tube adopts iron material to make.
The tension intensity that cloth concentrates on the indentation, there of former Cloth crossing tube is dispersed in the junction of indentation, there, convergence part and convergence part and circular arc tube wall, the defective of having avoided cloth easily to gall in indentation, there.
Because iron material is lower than aluminum price, iron Cloth crossing tube is lower than existing aluminum Cloth crossing tube cost, thereby has reduced the cost of making the said structure chair.
This Cloth crossing tube adopts the iron material roll forming, and the chair frame also adopts iron material, and Cloth crossing tube can adopt welding manner with the affixed of chair frame, is spirally connected or rivets affixed mode and improved production efficiency compared with adopting.

The specific embodiment:
See shown in the accompanying drawing 2, Cloth crossing tube (20), it comprises one section circular arc tube wall (11), connected two parallel straight pipe wall A (12), straight pipe wall B (13) and with straight pipe wall A (12), straight pipe wall B (13) straight pipe wall C connected vertically (14); Straight pipe wall C (14) is provided with breach (14a), the edge that straight pipe wall C (14) locates at breach (14a) is slick and sly shape, it is characterized in that: straight pipe wall C (14) locates vertically to extend respectively a convergence part (14b, 14c) downwards at breach (14a), convergence part (14b, 14c) is connected with the both sides of circular arc tube wall (14d) opening respectively, and the internal diameter of circular arc tube wall (14d) is greater than the width of breach (14a).This Cloth crossing tube adopts iron material to make.
The Cloth crossing tube method of manufacturing technology of this structure is: earlier the coiled strip of iron plate is sent into special-purpose roll extrusion machine, be rolled into type then after, use the crest welder welding forming, at last that weld grinding is smooth.
See shown in the accompanying drawing 3,4, the caliber of plastic round tube (40) is bigger than breach (14a) width, after a this plastic round tube (40) is respectively wrapped up at cloth (30) two, a cloth (30) that is enclosed with plastic round tube is made, Cloth crossing tube (10) is made the arc that adapts to the chair back and seat cushion, be located in after plastic round tube (40) is tightened together with its cloth (30) of parcel in the cavity volume (10a) of two corresponding Cloth crossing tubes (10), just become the chair back and seat cushion.Two corresponding Cloth crossing tubes (10) are packed on the chair frame (50), have promptly made chair, see shown in the accompanying drawing 5.The chair of this structure is widely used in family, the office.
Because the breach (14a) of this Cloth crossing tube (20) locates vertically to extend respectively a convergence part (14b, 14c) downwards, convergence part (14b, 14c) respectively is connected with a circular arc tube wall (14d) more then, cloth (30) concentrates on that tension intensity that the lacking of former Cloth crossing tube (14a) locate is dispersed in that breach (14a) is located, the junction of convergence part (14b, 14c) and convergence part (14b, 14c) and circular arc tube wall (14d), the defective of having avoided cloth easily to gall in indentation, there.
Because iron material is lower than aluminum price, iron Cloth crossing tube is lower than existing aluminum Cloth crossing tube cost, thereby has reduced the cost of making the said structure chair.
This Cloth crossing tube adopts the iron material roll forming, and the chair frame also adopts iron material, and Cloth crossing tube can adopt welding manner with the affixed of chair frame, is spirally connected or rivets affixed mode and improved production efficiency compared with adopting.
Can accept the Cloth crossing tube employing ferroalloy materials of this kind structure or the price that aluminium is made as the client, also can adopt ferroalloy materials or aluminium to make.
Not high as Cloth crossing tube requirement of strength to this kind structure, also can adopt plastics to make.
