Description
Technical field
The utility model relates to a kind of rivet, specifically, relates to a kind of internal lock peel type blind rivet.
Background technique
At present, the rivet kind being used for being riveted together by two or more workpiece has a lot, general rivet is made up of the shaft of rivet and rivet core, its main shortcoming is firm not after being riveted joint, rivet core can send the situation of moving displacement in the shaft of rivet, and the garland formed after staking is also even not, cannot clamp by riveted joint thing.
Model utility content
In order to solve above-mentioned the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of internal lock peel type blind rivet, to overcome defect of the prior art.
To achieve these goals, the utility model provides a kind of internal lock peel type blind rivet, described internal lock peel type blind rivet is provided with rivet nut and blind rivet, the center of described rivet nut offers central through bore, the bottom of described rivet nut is provided with the head of a nail, described blind rivet is inserted in described central through bore, and the inwall of the described central through bore with described head of a nail jointing place is equipped with inner ring body; Described blind rivet is disposed with interconnective ailhead, locking cylinder, cell body, connecting body, breaking groove and the body that comes off from top to bottom, wherein, the bottom surface of described ailhead is evenly equipped with four fin edges of a knife downward in wedge angle, and the diameter dimension of described locking cylinder is greater than the diameter dimension of described inner ring body and is less than the diameter dimension of ailhead (B1).
As further illustrating described internal lock peel type blind rivet of the present utility model, preferably, the diameter dimension of described locking cylinder is greater than the diameter dimension of described inner ring body.
As further illustrating described internal lock peel type blind rivet of the present utility model, preferably, come off described in the diameter dimension < of described breaking groove body diameter dimension < described in cell body diameter dimension < described in connecting body diameter dimension < described in lock cylinder diameter dimension < described in the diameter dimension of ailhead.
As further illustrating described internal lock peel type blind rivet of the present utility model, preferably, the internal diameter size of the head of a nail described in the diameter dimension < of connecting body described in the diameter dimension < of described inner ring body.
As further illustrating described internal lock peel type blind rivet of the present utility model, preferably, the internal diameter size of described central through bore and the diameter dimension of described locking cylinder match.
As can be seen here, internal lock peel type blind rivet of the present utility model is after staking, and the petal of garland can be made balanced, and highly unanimously, blind rivet can not produce displacement and loosen in rivet nut, and blind rivet can not expose the bottom plane of the head of a nail simultaneously.
Accompanying drawing explanation
Fig. 1 is the assembling schematic diagram of internal lock peel type blind rivet of the present utility model;
Fig. 2 is the structural representation of rivet nut of the present utility model;
Fig. 3 is the structural representation of blind rivet of the present utility model;
Fig. 4 is the structural representation after the empty riveting of internal lock peel type blind rivet of the present utility model.
Description of reference numerals is as follows:
Rivet nut A, central through bore A1, head of a nail A2, inner ring body A3, outer wall A4, blind rivet B, ailhead B1, fin edge of a knife B11, locking cylinder B2, cell body B3, connecting body B4, breaking groove B5, come off body B6.
Embodiment
Structure of the present utility model, feature and other objects is understood further in order to enable auditor, preferred embodiment appended by now combining is accompanied by accompanying drawing and is described in detail as follows, embodiment illustrated by this accompanying drawing is only for illustration of the technical solution of the utility model, and non-limiting the utility model.
First, please refer to Fig. 1, Fig. 1 is the assembling schematic diagram of internal lock peel type blind rivet of the present utility model.As shown in Figure 1, internal lock peel type blind rivet of the present utility model is provided with rivet nut A and blind rivet B.As shown in Figure 2, the center of rivet nut A offers central through bore A1, and the bottom of rivet nut A is provided with head of a nail A2, and blind rivet B is inserted in central through bore A1, and the inwall of the central through bore A1 with head of a nail A2 jointing place is equipped with inner ring body A3.
As shown in Figure 3, blind rivet B is disposed with interconnective ailhead B1, locking cylinder B2, cell body B3, connecting body B4, breaking groove B5 and the body B6 that comes off from top to bottom, wherein, the bottom surface of ailhead B1 is evenly equipped with four fin edge of a knife B11s downward in wedge angle, and the diameter dimension of locking cylinder B2 is greater than the diameter dimension of inner ring body A3 and is less than the diameter dimension of ailhead B1.
Thus, as shown in Figure 4, the internal diameter size of central through bore A1 matches with the diameter dimension of locking cylinder B2, thus locking cylinder B2 can be nested with in central through bore A1.When blind rivet B to be inserted in rivet nut A and to be drop-down, four fin edge of a knife B11 can cut brokenly the outer wall A4 of rivet nut A, make outer wall A4 form four freely balanced circular garland petals, clamp by riveted joint thing with this.When blind rivet B continues drop-down, diameter dimension due to locking cylinder B2 is greater than the diameter dimension of inner ring body A3, when the bottom of locking cylinder B2 touches inner ring body A3, inner ring body A3 can be extruded distortion, the material of distortion can flow in cell body B3, due in lock core B, the come off diameter dimension < of diameter dimension < connecting body B4 of diameter dimension < cell body B3 of body B6 of the diameter dimension < of breaking groove B5 locks the diameter dimension of the diameter dimension < ailhead B1 of cylinder B2, simultaneously, the internal diameter size of the diameter dimension < head of a nail A2 of the diameter dimension < connecting body B4 of inner ring body A3, thus, connecting body B4 can by locked in cell body B3 for the inner ring body A3 of distortion, make lock core B can not upward displacement.When continuation is drop-down and pulling force is greater than the breakpoint power of breaking groove B5, the body B6 that comes off, from breaking groove B5 breaking releasing, completes whole staking process.
It is to be understood that, above-mentioned model utility content and embodiment be intended to prove the utility model the practical application of technological scheme is provided, should not be construed as the restriction to the utility model protection domain.Those skilled in the art in spirit of the present utility model and principle, when doing various amendment, equivalent replace or improve.Protection domain of the present utility model is as the criterion with appended claims.
