It can complete to assemble in frame insertion connecting cylinder, assembling is very convenient, and production efficiency is high, and whole sleeve body and connecting cylinder are adopted
Made of plastic, production cost is relatively low, can be mass produced.
Brief description of the drawings
The present invention is further described with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of connecting rod；
Fig. 2 is the structural representation of the present embodiment；
Fig. 3 is the structural representation of sleeve body；
Fig. 4 is the structural representation of connecting cylinder；
Fig. 5 is Fig. 4 upward view.
Embodiment
Referring to figs. 1 to Fig. 5, the present embodiment provided it is a kind of be used to lifting the bracket sleeve tube of headrest, including for sand
The sleeve body 1 of main body connection, the connecting cylinder 2 in insertion sleeve main body 1 are sent out, is provided with the sleeve body 1 and is inserted for connecting cylinder 2
The endoporus entered, the outer surface of the sleeve body 1 are provided with the latch 3 of outwardly convex, when sleeve body 1 inserts the groove of sofa main body
When in hole, latch 3 withstands on the inwall of slotted eye so that and sleeve body 1 is fixed in slotted eye, can not be extracted, here, the latch
3 can be the planforms such as ratchet, salient point, have identical technique effect.The connecting cylinder 2 is provided with and connecting rod of support 4
The connecting hole 5 of connection, is provided with inwardly protruded bulge loop 6 in the connecting hole 5, the bulge loop 6 just can with connecting rod 4
Connection screens is engaged, and connecting rod 4 is moved after inserting, and the outer surface of the connecting cylinder 2 is provided with the ratchet of outwardly convex
7, endoporus inwall is provided with barb tooth corresponding with ratchet 7.
As preferred embodiment, the sleeve body 1 is made of plastics and its underpart is segmented into pintongs, and adjacent two
Gap is left between valve, because sleeve body 1 is made of plastics, therefore when inserting sofa main body, one is may be present between each valve
Fixed deformation, it is convenient to insert in slotted eye, after inserting slotted eye, it is inserted into connecting cylinder 2, connecting cylinder 2 is by each valve distending of sleeve body 1
And it is close to slotted eye inwall, to reach more preferable fixed effect.Similarly, the connecting cylinder 2 is made of plastics and lower part
Two valves are segmented into, gap is left between adjacent two valve, because connecting cylinder 2 is made of plastics, therefore in insertion sleeve main body 1, respectively
Certain deformation may be present between valve, it is convenient to insert in endoporus, after inserting endoporus, connecting rod 4 is inserted into, connecting rod 4 will connect
Each valve distending of cylinder 2 simultaneously makes it be close to endoporus inwall, to reach more preferable fixed effect.
Further, to avoid sleeve body 1 and connecting cylinder 2 exposed, the top of the sleeve body 1 is provided with trim 8, institute
State the mode that trim 8 is connected through a screw thread to be connected with sleeve body 1, certainly, here, the trim 8 can also pass through card
The mode connect is connected with sleeve body 1.Spacing for convenience of carrying out, the top of the connecting cylinder 2, which is provided with, is against the top of sleeve body 1
Limited block 9, the middle part of the sleeve body 1 is provided with position-limited edge 10.
The preferred embodiments of the present invention are the foregoing is only, as long as realizing the skill of the object of the invention with essentially identical means
Art scheme is belonged within protection scope of the present invention.
