Description

Pressure rivet with inhibiting effect

Technical Field

The utility model relates to a rivet technical field, concretely relates to suppression adds pressure rivet.

Background

The rivet is a nail-shaped object used for connecting two parts (or components) with through holes and caps at one ends, the riveted parts are connected by self deformation or interference in riveting, the rivet is of various types and is in a common use regardless of form, such as R-shaped rivet, fan rivet, self-plugging rivet (core-driving rivet), tree-shaped rivet, half-round head, flat head, half-hollow rivet, solid rivet, countersunk head rivet, self-plugging rivet and hollow rivet, and the rivet is usually connected by self deformation to be riveted.

The existing rivet has poor durability, and particularly can loosen after being used outdoors for a long time, so that the connection reliability is reduced.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a firm structure can improve the suppression effect to the riveting piece locking force and add the pressure rivet.

The utility model discloses a following technical scheme realizes: suppression pressure rivet, including end cap, rivet cover and rivet body, be equipped with the fracture ring channel on the rivet body, the upper portion of rivet cover is equipped with at least a pair of vertical holding chamber, the airtight setting in holding chamber, the holding intracavity is equipped with a plurality of triangular pyramids, the bottom of triangular pyramid is fixed in on the holding chamber is close to one side inner wall of rivet cover inner wall, the pointed portion of triangular pyramid is contradicted on the holding chamber is close to one side inner wall of rivet cover outer wall the holding intracavity, be located the outside storage of triangular pyramid has the bonding agent.

The bottom of end cap is equipped with the recess, the recess is located the junction of end cap and rivet cover.

The outer diameters of the upper portion and the lower portion of the rivet body are the same as the inner diameter of the rivet sleeve, and the outer diameter of the middle portion of the rivet body, which is located below the breaking annular groove, is larger than the inner diameter of the rivet sleeve.

The lower part of the rivet body is provided with an external thread.

Compared with the prior art, the utility model discloses at work, upwards take out the rivet body, make the rivet cover take place deformation, it is concrete, the upper portion and the pilot hole of rivet cover closely laminate, and simultaneously, because the upper portion of rivet cover is equipped with the extrusion, the one side inner wall that the holding chamber is close to the rivet cover outer wall is destroyed to the triangular cone, the adhesive flows out, and overflow along the clearance between rivet cover and the pilot hole, and is further, take out of rivet body, make the lower part of rivet cover produce and buckle, and laminate the bottom of riveting piece, the adhesive that spills over can be full of between the lower part of rivet cover and the bottom of riveting piece, and thus, between rivet cover and the pilot hole, joint strength between rivet cover and the riveting piece, and firm in structure can improve the locking force of riveting piece.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged schematic view of the structure at A in FIG. 1;

in the figure: 1. an end cap; 10. a groove; 2. a rivet sleeve; 3. a rivet body; 31. breaking the annular groove; 32. an accommodating cavity; 33. a triangular cone; 34. an adhesive; 35. and (4) external threads.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the suppression effect adds pressure rivet, including end cap 1, rivet cover 2 and rivet body 3, rivet body 3 is last to be equipped with fracture ring channel 31, the upper portion of rivet cover 2 is equipped with at least a pair of vertical holding chamber 32, holding chamber 32 is airtight to be set up, be equipped with a plurality of triangular cones 33 in the holding chamber 32, the bottom of triangular cones 33 is fixed in on holding chamber 32 is close to one side inner wall of rivet cover 2 inner wall, the pointed portion of triangular cones 33 is contradicted holding chamber 32 is close to on one side inner wall of rivet cover 2 outer wall the holding chamber 32 in, be located the outside storage of triangular cones 33 has adhesive 34. Upwards take out rivet body 3 for rivet cover 2 takes place deformation, it is concrete, the upper portion and the pilot hole of rivet cover 2 closely laminate, and simultaneously, because the upper portion of rivet cover 2 is equipped with the extrusion, the triangle cone 33 destroys one side inner wall that holding chamber 32 is close to rivet cover 2 outer wall, adhesive 34 flows out, and overflow along the clearance between rivet cover 2 and the pilot hole, furthermore, rivet body 3 takes out, make the lower part of rivet cover 2 produce and buckle, and laminate the bottom of riveting piece, adhesive 34 that overflows can be full of between the lower part of rivet cover 2 and the bottom of riveting piece, thus, between rivet cover 2 and the pilot hole, joint strength between rivet cover 2 and the riveting piece, the sound construction, can improve the locking force of riveting piece.

The bottom of the end cap 1 is provided with a groove 10, and the groove 10 is positioned at the joint of the end cap 1 and the rivet sleeve 2. Set up recess 10, leave the surplus for the deformation of end cap 1 for the bottom structure of end cap 1 can adapt to different riveting piece top shapes, has just also improved the locking force of rivet to the riveting piece more firm.

The outer diameters of the upper part and the lower part of the rivet body 3 are the same as the inner diameter of the rivet sleeve 2, and the outer diameter of the middle part of the rivet body 3 below the fracture annular groove 31 is larger than the inner diameter of the rivet sleeve 2. Thus, the rivet sleeve 2 is deformed by the withdrawal of the rivet body 3, the overflow of the adhesive 34 is promoted, and the strength and durability after the riveting are improved.

The lower part of the rivet body 3 is provided with an external thread 35. Set up external screw thread 35, can be after rivet body 3 breaks, establish the sleeve pipe of adaptation soon in rivet body 3's lower part for the exposed rivet body 3 of shroud improves aesthetic property and security.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
