Abstract
The utility model relates to a sleeve connecting mechanism for automobile interior decoration, which comprises a cylindrical part and a sleeve part, wherein the middle part of the sleeve part is provided with a jack matched with the diameter of the cylindrical part; the inner wall of the sleeve part is provided with an insertion groove positioned at the edge of the insertion hole, and the inner wall of the sleeve part is also provided with a slope-shaped channel which obliquely extends downwards from the bottom of the insertion groove and a positioning step positioned at the tail part of the slope-shaped channel; the middle part of the cylindrical part is provided with a convex part which is matched with the inserting groove, when the cylindrical part enters the inserting hole, the convex part can enter the sleeve part from the inserting groove and slide to the positioning step through the groove wall of the slope-shaped groove, so that the cylindrical part is stably inserted in the sleeve part; and the upper end of the cylindrical part is provided with a limiting plate with the diameter larger than the inner diameter of the jack.
Description
Technical Field
The utility model relates to a sleeve coupling mechanism for automotive interior.
Background
In the automotive interior, a plug-in type sleeve structure often appears, at present, a plurality of sleeve parts are difficult to match in place after being clamped into other parts, looseness (larger sleeve or thinner clamped part) or incapability of clamping pins (smaller sleeve or thicker clamped part) easily appears, and a process window is smaller.
The design method is mainly used for expanding the process window of the sleeve part, and the sleeve part is clamped in place more easily by optimizing the shape of the clamping surface contacted with the clamping pin on the sleeve part.
Disclosure of Invention
As the background art said, the utility model aims to provide a be convenient for peg graft and fix a position accurate sleeve coupling mechanism for automotive interior, specifically realize by following technical scheme:
a sleeve connecting mechanism for automotive interiors comprises a cylindrical part and a sleeve part, wherein a jack with the diameter matched with that of the cylindrical part is arranged in the middle of the sleeve part; the inner wall of the sleeve part is provided with an insertion groove positioned at the edge of the insertion hole, and the inner wall of the sleeve part is also provided with a slope-shaped channel which obliquely extends downwards from the bottom of the insertion groove and a positioning step positioned at the tail part of the slope-shaped channel; the middle part of the cylindrical part is provided with a convex part which is matched with the inserting groove, when the cylindrical part enters the inserting hole, the convex part can enter the sleeve part from the inserting groove and slide to the positioning step through the groove wall of the slope-shaped groove, so that the cylindrical part is stably inserted in the sleeve part; and the upper end of the cylindrical part is provided with a limiting plate with the diameter larger than the inner diameter of the jack.
The sleeve connecting mechanism for the automotive interior is further designed in that at least two protruding parts are uniformly distributed in the middle of the cylindrical part; the number of the inserting grooves, the sloping channels and the positioning steps is consistent with that of the convex parts.
The sleeve connecting mechanism for the automotive interior is further designed in that a fillet convenient to slide is arranged at the end part of the protruding part.
The sleeve connecting mechanism for the automotive interior is further designed in that a plurality of positioning thorns are arranged on the step surface of the positioning step.
The beneficial effects of the utility model reside in that:
the utility model discloses utilize the slope shape channel that the slope set up, when the cylindricality piece is pegged graft in the cover barrel spare, rotatory cylindricality piece can be so that to peg graft accurately to finally utilize the slight elastic deformation of bellying, make grafting stable in structure.
Drawings
Fig. 1 is a schematic structural view of the column member of the present invention.
Fig. 2 is a schematic cross-sectional structure of the sleeve member of the present invention.
Figure 3 is a schematic view of a partially flat developed configuration of the inner wall of the sleeve member.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
the sleeve connecting mechanism for the automotive interior comprises a cylindrical part 1 and a sleeve part 2, wherein a jack 21 with the diameter matched with that of the cylindrical part is arranged in the middle of the sleeve part; the inner wall of the sleeve part is provided with an inserting groove 22 positioned at the edge of the inserting hole, and the inner wall of the sleeve part is also provided with a slope-shaped groove 23 which extends downwards from the bottom of the inserting groove in an inclined way and a positioning step 24 positioned at the tail part of the slope-shaped groove; the middle part of the cylindrical part is provided with a convex part 11 which is matched with the plug-in groove, when the cylindrical part enters the plug hole, the convex part can enter the sleeve part from the plug-in groove and slide to the positioning step through the groove wall of the slope-shaped groove, so that the cylindrical part is stably plugged in the sleeve part; and the upper end of the cylindrical part is provided with a limiting plate 12 with the diameter larger than the inner diameter of the jack.
When the cylindrical part 1 is inserted into the sleeve part 2, the protruding part enters the insertion groove 22, then the cylindrical part 1 is rotated, the protruding part 22 enters the slope-shaped groove 23 from the insertion groove 22, the upper end of the protruding part 11 abuts against the groove wall of the slope-shaped groove, the cylindrical part enters the positioning step 24 under the limitation of the groove wall, in the process, the cylindrical part 1 stably enters the sleeve part, the tensioning effect is formed between the protruding part and the limiting plate, and the insertion effect is stable.
Specifically, the number of the convex parts is not less than two, and the convex parts are uniformly distributed in the middle of the cylindrical part; the number of the inserting grooves, the sloping channels and the positioning steps is consistent with that of the convex parts.
In order to facilitate rotation and reduce rotation resistance, the end part of the protruding part is provided with a fillet which is convenient for sliding. As a further optimization, a plurality of positioning spines 25 can be arranged on the step surface of the positioning step, so that the structural stability is further enhanced.
