Abstract

The utility model relates to a rivet structure which comprises a rivet body, a rivet rod and a gasket, wherein a small cylinder is arranged at the upper part of the rivet body; a large cylinder is arranged in the middle of the rivet body; a round plate is arranged at the bottom of the rivet body; a step is formed between the small cylinder and the large cylinder; a through hole is formed in the rivet body; and the rivet rod has a spherical head. The rivet structure is used for single-side mounting in a relatively narrower space, and has the advantages that after riveting, riveted parts can rotate freely and can move with a certain displacement in the axial direction, which facilitates adjusting of the parts.

Description

The staking structure

Technical field

The utility model relates to a kind of riveted structure, especially relates to the riveted structure that a kind of staking is used.

Background technique

Need under part rotation or the axially movable occasion of short distance at some; The capital adopt a bolt, nut, sleeve pipe and pad or a double-screw bolt, two nuts and two pads etc. similarly structure come union piece; But in some narrow spaces and the place that can only adopt single face to install; Owing to being difficult to stretch into, people's hand cause to adopt said structure to connect; And when adopting said structure to connect, owing to need the quantity of combiner more, very inconvenient when in use.In the occasion of some riveted joints, rivet usually is riveted together two plates, axially can not voluntary activity, need part can movable occasion under, just inapplicable.

Summary of the invention

The utility model technical problem to be solved is narrow very, can not the occasion of two-sided fixed connection under, provide a kind of and can connect the staking structure that single face that several parts and part can move therein connects usefulness fast.

The technological scheme that its technical problem of the utility model solution is taked is: a kind of staking structure; Comprise rivet body, staking bar and pad, individual small column is arranged at described rivet body top, and there is individual big column at the middle part; Individual disk is arranged at the bottom; Between small column and big column, step is arranged, there is individual through hole the inside of rivet body, and described staking bar has ball head.

Can smoothly the staking bar be broken in order to make in riveted joint, there is the hole groove that falls in inwards the ball head of described staking bar and the joint of bar.

For in riveted joint, ball head can get in the rivet body hole smoothly, and there is chamfering at the small column interior bone place of described rivet body.

The beneficial effect of the utility model is: this kind staking structure can be used for the narrower and small occasion of installing with single face in space, and after riveted joint, can rotate freely, and on axial direction, has certain displacement to move, and conveniently part is adjusted.

Embodiment

Like Fig. 1, Fig. 2 and a kind of staking structure 1 shown in Figure 3; Comprise rivet body 1, staking bar 10 and pad 3, individual small column 2 is arranged at described rivet body 1 top, and there is individual big column 4 at the middle part; Individual disk 5 is arranged at the bottom; Between small column 2 and big column 4, step 11 is arranged, there is individual through hole 12 inside of rivet body 1, and described staking bar 10 has ball head 7; The ball head 7 of described staking bar 10 has the hole groove 8 that falls in inwards with the joint of bar 9; There is chamfering 6 at small column 2 interior bone 12 places of described rivet body 1.

As shown in Figure 4 on the big column 4 of rivet body 1, put into the part that will rivet; Pad 3 is placed on the step 11 on the rivet body 1, the bar 9 on the pulling staking bar 10, the chamfering 6 of the ball head 7 of staking bar 10 on through hole 12 drawn in the small column 2; Ball head 7 swells small column 2; Pad 3 is stuck on the step 11, ruptures in hole groove 8 places of bar 9 this moment on staking bar 10, and staking finishes.

Owing on rivet body 1, adopt step 11, after staking finished, the distance between pad 3 and disk 5 did not change, and the part between them just can move axially, and can put into a plurality of parts and connect.

Claims
