Abstract
The utility model discloses a kind of car seat headrest pipes, main body is cylindrical tube made of steel plate rolls, and it is welded and fixed together again after being spliced at seaming position using dovetail configuration, outwardly convex plane is rushed around the weld seam of cylindrical tube to be used as by back elbow pipe welding plane, it is described to be centrally positioned in cylindrical tube up and down by back elbow pipe welding plane.Meanwhile the invention also discloses above-mentioned car seat headrest pipe mounting structures.Compared to cylindrical shape seat headrest tube made of steel pipe truncation, it can increase and the bonding area by back bend pipe, it is ensured that with the weld strength for leaning on back bend pipe, reduce welding difficulty；And combine to be centrally positioned in up and down in cylindrical tube and lean on back elbow pipe welding plane, rather than the punching press plane of the outwardly convex of entire height is penetrated through, integral strength is more preferable.
Description
Technical field
The utility model relates to automotive seating art fields, and in particular to a kind of car seat headrest pipe and its installation knot
Structure.
Background technique
Car seat headrest pipe is welded on back bend pipe, for installing chair headrest.Chair headrest pipe is mostly cylinder
Pipe partially uses square tube.It is that steel pipe is truncated for the chair headrest pipe of cylindrical tube structure.It is main existing for the structure
Problem is: bonding area is small, and welding difficulty is high.
Utility model content
The utility model is intended to provide a kind of car seat headrest pipe, increases bonding area, reduces welding difficulty.
For this purpose, the technology employed by the present utility model is a kind of car seat headrest pipe, main body for steel plate rolls and
At cylindrical tube, and at seaming position using dovetail configuration splicing after be welded and fixed together again, around the weld seam of cylindrical tube
Outwardly convex plane is rushed to be used as by back elbow pipe welding plane, it is described to be centrally positioned in up and down by back elbow pipe welding plane
In cylindrical tube.
Anti- misloading notch is provided at the top of the cylindrical tube, as a preferred embodiment of the above solution, to ensure plastic catheter one
It is secondary to be inserted in place, improve the assembly efficiency of plastic catheter.
Further, the dovetail configuration totally two, respectively close to the upper and lower ends of cylindrical tube, further increase splicing can
By property.
Meanwhile the utility model additionally provides a kind of above-mentioned car seat headrest pipe mounting structure, the automotive seat head
Pipe is rested the head on by leaning on back elbow pipe welding plane and leaning on back elbow pipe welding, and two car seat headrest pipes are by back bend pipe
Front is symmetrical set, described that recession plane corresponding with back elbow pipe welding plane is leaned on is provided on back bend pipe.
The utility model has the beneficial effects that can increase and backrest compared to cylindrical shape seat headrest tube made of steel pipe truncation
The bonding area of upper bend pipe, it is ensured that with the weld strength for leaning on back bend pipe, reduce welding difficulty；And it combines and is centrally positioned in up and down
Back elbow pipe welding plane is leaned in cylindrical tube, rather than penetrates through the punching press plane of the outwardly convex of entire height, integral strength
More preferably.
Detailed description of the invention
Fig. 1 is the schematic diagram of the car seat headrest pipe of the utility model.
Fig. 2 is the schematic diagram of the car seat headrest pipe mounting structure of the utility model.
Figure is laterally truncated in the middle part that Fig. 3 is Fig. 2.
Specific embodiment
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail:
In conjunction with shown in Fig. 1-Fig. 3, a kind of car seat headrest pipe and its mounting structure, main body are made of steel plate rolls
Cylindrical tube 1, and be welded and fixed together again after being spliced at seaming position using dovetail configuration 2.Dovetail configuration 2 preferably totally two,
Respectively close to the upper and lower ends of cylindrical tube 1, but two are not limited to, can be set as needed.
Outwardly convex plane is rushed around the weld seam of cylindrical tube to be used as by back elbow pipe welding plane 3, it is curved by back
About 3 pipe welding plane is centrally positioned in cylindrical tube 1.It is not the entire headrest tube of perforation by back elbow pipe welding plane 3
Highly, it but is centrally located up and down, so that the plane for the outwardly convex being stamped to form is also functioned to the effect for increasing integral strength, prevent
Chair headrest pipe stress deformation.
The top of cylindrical tube 1 is provided with anti-misloading notch 4, to ensure that plastic catheter is once inserted in place.
The mounting structure of above-mentioned car seat headrest pipe are as follows: car seat headrest pipe is by leaning on back elbow pipe welding plane 3
It is welded with by back bend pipe 5, and two car seat headrest pipes are symmetrical set in the front by back bend pipe 5, lean on back
Recession plane corresponding with back elbow pipe welding plane 3 is leaned on is provided on bend pipe 5.
