Abstract
The invention discloses a blind hole bushing structure which comprises an annular main body part (1) formed in a wrapping circle mode, wherein a riveting groove (11) is formed in one end of the annular main body part (1), a protruding part (12) which is integrally connected is arranged at the other end of the annular main body part (1), the protruding part (12) is clamped into the riveting groove (11) in a seamless mode, and a plurality of round blind holes (13) are formed in the outer surface of the annular main body part (1) along the circumferential direction of the annular main body part. The blind hole bushing structure provided by the invention is simple in structure, easy to produce, and capable of preventing glue overflow during injection molding and increasing the retention force after injection molding.
Description
Technical Field
The invention relates to a blind hole bushing structure, and belongs to the technical field of bushing structure design.
Background
The lining is a matching part used outside mechanical parts to achieve the functions of sealing, wear protection and the like, and is a ring sleeve playing the role of a gasket. In the prior art, the structure of bush is comparatively single, generally is simple ring structure, can have following technical defect like this: firstly, glue is easy to overflow in the injection molding production process; secondly, the retention force is insufficient after injection molding.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a blind hole bushing structure which is simple in structure, easy to produce, capable of preventing glue overflow during injection molding and increasing the retention force after injection molding.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the utility model provides a blind hole bush structure, includes the fashioned annular main part of peridium, riveting groove has been seted up to annular main part one end, the annular main part other end is provided with the bellying of body coupling, the seamless card of bellying goes into rivet in the groove, the circular blind hole of a plurality of has been seted up along its border direction on the annular main part surface.
The width of the riveting groove is 1/3 of the height of the annular main body part.
The height of the annular main body part is 4-15 mm.
The thickness of the annular main body part is 0.8-1.2 mm.
The inner diameter of the annular main body part is 4-10 mm.
The diameter of the round blind hole is 1.5-2.0 mm, and the depth of the round blind hole is 1/3-1/2 of the thickness of the annular main body part (1).
The number of the round blind holes is 3 to 5.
The riveting groove and the bulge are rectangular.
The invention has the beneficial effects that: the blind hole bushing structure provided by the invention has the advantages that the main body structure is an annular main body part formed by rounding, a riveting groove is formed in one end of the annular main body part, the other end of the annular main body part is provided with a protruding part which is integrally connected, the protruding part is seamlessly clamped into the riveting groove, and the occurrence of injection molding glue overflow can be prevented by arranging the riveting groove; a plurality of round blind holes are formed in the annular main body part along the circumferential direction of the annular main body part, and the mode of increasing the through holes in the side face can increase the holding force of the injection molded bushing.
Drawings
Fig. 1 is a schematic structural diagram of a blind hole bushing structure according to the present invention.
The reference numbers in the figures are as follows: 1-an annular body portion; 11-riveting and pressing a groove; 12-a boss; 13-round blind hole.
Detailed Description
The present invention is further described with reference to the accompanying drawings, and the following examples are only for clearly illustrating the technical solutions of the present invention, and should not be taken as limiting the scope of the present invention.
As shown in FIG. 1, the invention provides a blind hole bushing structure, which comprises an annular main body part 1 formed by rounding, wherein the height of the annular main body part 1 is 4-15 mm, the inner diameter of the annular main body part 1 is 4-10 mm, and the thickness of the annular main body part 1 is 0.8-1.2 mm.
Compared with the prior art, the difference of the annular main body part 1 in the bushing main body is that a riveting groove 11 is formed in one end of the annular main body part 1, and the width of the riveting groove 11 is 1/3 of the height of the annular main body part 1. The other end of the annular main body part 1 is provided with an integrally connected bulge part 12, and the bulge part 12 is seamlessly clamped into the riveting groove 11. According to the invention, the riveting groove structure is arranged, so that the condition of glue overflow during injection molding can be prevented. In the present embodiment, the caulking groove 11 and the boss 12 are rectangular in shape.
A plurality of round blind holes 13 are formed in the outer surface of the annular main body part 1 along the circumferential direction of the annular main body part, and the number of the round blind holes 13 is 3-5. In the present embodiment, the number of the circular blind holes 13 is preferably 4. In the present embodiment, the diameter of the circular blind hole 13 is 1.5 to 2.0mm, and the depth is 1/3 to 1/2 of the thickness of the annular main body 1. According to the invention, the circular blind hole is formed in the annular main body part, the retention force of the bush after injection molding can be increased by increasing the through hole on the side surface, and the retention force of the through hole bush after injection molding is 50-300N through experimental determination.
The above is only a preferred embodiment of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention, and such modifications and adaptations are intended to be within the scope of the invention.
