Embodiment 1

[0026] Such as Figure 1-2 As shown, a plug-in assembly of a car seat headrest includes an insertion tube 2 and an insertion rod 4 inserted in the insertion tube 2 and whose shape matches the inner shape of the insertion tube 2 . The insertion rod 4 is used to be connected with the headrest, and the insertion tube 2 is used to be fixed on the interior floor of the automobile.

[0027] The intubation tube 2 is a round tube, hollow and open at one end. The opening end of the intubation tube 2 is provided with two circumferentially distributed grooves 22 , and the insertion rod 4 is provided with two protrusions 42 respectively matched with the two grooves 22 . Specifically, the two ends of the insertion rod 4 are respectively a head 44 and a tail 46 , and the protrusion 42 is arranged on the head 44 . The two grooves 22 form an angle of 90° at the circumferential position of the cannula 2 . More specifically, the groove walls on both sides of the opening end of the groove 22 a...

Embodiment 2

[0031] Such as image 3 As shown, a plug-in assembly of a car seat headrest differs from Embodiment 1 in that the rib 6 is arranged on the outer wall of the plug-in rod 4 . When the insertion rod 4 is inserted into the intubation tube 2 , the rib 6 of the insertion rod 4 just abuts against the inner wall of the intubation tube 2 .

Embodiment 3

[0033] Such as Figure 4-5 As shown, a plug-in assembly of a car seat headrest differs from Embodiment 1 in that: the insertion tube 2 is also provided with a number of adjustment holes 8 distributed axially discretely, and the insertion tube 2 can be fixed to the insertion tube by clamping. Any adjustment hole 8 position of the pipe 2. In addition, two ribs 6 are circumferentially distributed on the inner wall of the cannula 2 . The protrusion 42 is arranged on the tail 46 of the insertion rod 4 , and the depth of the groove 22 covers all the adjusting holes 8 distributed in the axial direction.

[0034] Specifically, the intubation tube 2 is provided with two groups of adjustment holes facing each other in the circumferential direction, and each group is composed of a single adjustment hole 8 arranged in the axial direction, that is, the two groups of adjustment holes 8 correspond one-to-one, and the corresponding two adjustment holes 8 are circumferentially aligned. Relat...

Abstract

The invention discloses an inserting-connection assembly for an automobile seat headrest. The inserting-connection assembly comprises an inserting tube and an inserting link arranged in the inserting tube in an inserting manner, and is characterized in that the inserting tube is hollow and provided with an open end, the open end of the inserting tube is provided with at least two grooves distributed circumferentially, and the inserting link is provided with a plurality of bumps matched with the grooves. According to the inserting-connection assembly for the automobile seat headrest, the inserting tubes are provided with the grooves matched with the bumps on the inserting link, so that the inserting link can be more stably locked and prevented from circumferentially rotating relating to the inserting tube. Meanwhile, the inserting-connection assembly is good in structural stability, thus being capable of being produced by plastic material with light weight, and saving in cost.

Description

technical field [0001] The invention relates to a plug-in assembly, which belongs to the technical field of mechanical structures. Background technique [0002] With the development of modern society, automobiles have become more and more popular as a means of transportation. As an important component of the car interior, car seats provide drivers and passengers with a comfortable and safe driving and riding environment. In particular, the headrest provided on the seat can protect the head and neck of the driver and passengers. Common head restraint has plunger, is connected with the inserting tube that is fixed on the car body. However, the existing insertion rod is directly inserted into the cannula and is easy to rotate in the circumferential direction. Contents of the invention [0003] A plug-in assembly for a car seat headrest, comprising an insertion tube and an insertion rod inserted in the insertion tube, characterized in that the insertion tube is hollow and h...
