Description
Technical field
The utility model relates to a kind of sleeve pipe, is specifically related to a kind of sleeve pipe that is used for automotive headrest.Belong to the vehicular spare parts technical field.
Background technology
At present, generally all be provided with a headrest on the backrest of automotive seat, can play support and protective effect the chaufeur head.For alleviating the driver fatigue degree, existing driver's seat is provided with the headrest at the scalable elevation angle, plays the purpose that alleviates the driver fatigue degree.The patent No. is that 200520065786.1 utility model patent discloses a kind of adjustable automotive headrest frame that automatically resets, it comprise two respectively with the left and right sides intubate and the intermediate pipe of tranverse connecting rod, be clamped in clip on the intermediate pipe, be fixed in the adapter plate on the clip, puller system, two intubate are parallel, tranverse connecting rod is connected with intermediate pipe is scalable respectively, puller system connects two intubate, is provided with some chucking teeth on intubate.This kind automotive headrest adopts the jack on the backrest of intubate and automotive seat to be connected, and regulates distance between two intubate by puller system, can be installed on the different seats, and comformability is strong, good fixing effect.But also there is following shortcoming in the jack bonded assembly automotive headrest on the backrest of this employing intubate or inserted link and automotive seat: 1, because the radius of intubate or inserted link is changeless, in the time of in it being installed to its big jack of radius ratio, be prone to and rock, make the people feel uncomfortable; Simultaneously, it can not be installed in its little jack of radius ratio, has the shortcoming of narrow application range.2, the automotive seat at the different radii jack need to produce respectively the automotive headrest that adapts, and are unfavorable for the production in enormous quantities of product, even the duplication of production of product may occur, and productive costs is raise.
The utility model content
The shortcoming that the purpose of this utility model is the narrow application range that exists of existing automotive headrest, can not produce in enormous quantities, manufacturing cost is high, a kind of sleeve pipe that is used for automotive headrest is provided, the automotive headrest that is used of sleeve pipe has characteristics applied widely, as to be suitable for producing in enormous quantities, having helped reducing manufacturing cost therewith.
The purpose of this utility model can reach by following measure:
A kind of sleeve pipe that is used for automotive headrest comprises union body, and its constructional feature is: union body is made of the hollow cylinder of both ends open, is provided with flange at an end of union body, is provided with an arc notch in the junction of flange and union body; Union body and the flange structure that is formed in one; Perhaps union body and flange are independent moulding, constitute fixed connection structure by welding.
When design is used the internal diameter of union body is designed to corresponding with the external diameter of the intubate/inserted link of automotive headrest, with the external diameter of union body be designed to motor vehicle seat back on the internal diameter of headrest jack corresponding.
The purpose of this utility model can also reach by following measure:
A kind of embodiment of the present utility model is: the internal diameter of union body can be 10mm, and its external diameter H can be 12～16mm.
A kind of embodiment of the present utility model is: the external diameter H of union body can be 12mm, 12.5mm, 12.7mm, 13.8mm, 14mm or 16mm.
A kind of embodiment of the present utility model is: union body and the flange structure that can be formed in one.
A kind of embodiment of the present utility model is: union body 1 can adopt plastics or metallic material to make.
The beneficial effects of the utility model are:
1, the utility model is by inserting sleeve pipe in the jack of automotive seat, by passing the arc notch on the sleeve pipe sidewall under the application force that is buckled in elastic element in the automotive seat jack, stick in the groove on the automotive headrest intubate, make intubate fix, reach the fixed car headrest, be a kind of easy mounted-dismounted type structure, have the beneficial effect simple, easy to use of pegging graft.
2, the utility model can be selected the sleeve pipe that is suitable for mutually for use according to jack internal diameter on the automotive seat, makes the Applicable scope of automotive headrest more extensive; Simultaneously, when making automotive headrest, only need the headrest of the external diameter H minimum of manufacturing intubate/inserted link to get final product, cooperate various sleeve pipes to use the automotive seat that can satisfy various different jacks together, therefore can make in enormous quantities, help lowering manufacturing cost.Has simple in structure, easy to operate beneficial effect simultaneously.

The specific embodiment
Specific embodiment 1:
See figures.1.and.2, present embodiment comprises union body 1, and described union body 1 is the hollow cylinder of both ends open, and a port of described union body 1 is provided with flange 11, has an arc notch 12 near the sidewall of the union body the flange 11 1.The internal diameter L of described union body 1 is 10mm, and its external diameter H is 12mm.Described union body 1 adopts plastics to make.Described union body 1 and flange 11 structure that is formed in one.
In the practical application, earlier union body 1 is inserted in the jack 31 of automotive seat 3, sleeve pipe is fixed on the jack 31 by the flange on the union body 1 11; Then with two intubate/inserted links 21 of automotive headrest 2 from the port of flange 11 ends of union body 1 passes and inserts jack 31 on the automotive seat 3, be provided with a buckle 32 in the jack 31, buckle 32 is fixing with seat 3 by elastic element 33, when intubate/inserted link 21 inserts jack 31, buckle 32 is subjected to the influence of intubate/inserted link 21 application forces and moves backward, make elastic element 33 thereafter be in squeezed state, along with going deep into of intubate/inserted link 21, arc notch 12 in the groove alignment sleeve pipe on intubate/inserted link 21, and because the existence of intubate/inserted link 21 upper grooves, make buckle 32 forefront pressures disappear, application force by elastic element 33, buckle 32 will be stuck in the groove on intubate/inserted link 21 by arc notch 12, thereby the intubate of making/inserted link 21 is fixed in the jack.
