Refering to Fig. 1 and Fig. 2, the application provides a kind of detachable blind rivet, including blind rivet body part 1 and core bar 2；Institute
Stating blind rivet body part 1 includes stop part 11, tube 12 and supporting part 13；The stop part 11 is connected to tube 12
One end, for being against the first side of workpiece 3 to be connected；The supporting part 13 is connected to the other end of tube 12；The core bar 2
It is connected by screw thread with blind rivet body part 1, and core bar 2 is contained in tube 12；The first end and supporting part of the core bar 2
13 first end adaptation, when the core bar 2 is moved to first direction in the tube 12, the first end of core bar 2 can act on branch
The first end of support part 13, the second end of supporting part 13 is set to be rotated around the first end of supporting part 13, whole supporting part 13 is opened up laterally
Open the second side for being against workpiece 3 to be connected.
In this embodiment, core bar 2 is to be connected by screw thread with blind rivet body part 1, and certainly, core bar 2 can also pass through
Other modes are connected with blind rivet body part 1.
The detachable blind rivet that the application provides, its operation principle are as follows：
Refering to Fig. 3, Fig. 6 and Fig. 7, blind rivet body part 1 is passed through to the through hole of workpiece 3 to be connected, supports stop part 11
In the first side of workpiece 3 to be connected；Rotation core bar 2 makes core bar 2 be moved in tube 12 to first direction, until core bar 2
First end acts on the first end of supporting part 13, the second end of supporting part 13 is rotated around the first end of supporting part 13, until whole
Individual supporting part 13 deploys to be against the second side of workpiece 3 to be connected laterally, that is, completes connecting moves；
When needing dismounting, rotation core bar 2 makes core bar 2 be moved in tube 12 to second direction, until the first of core bar 2
End no longer acts on the first end of supporting part 13, after the limitation of core bar 2 is lost, be folded up supporting part 13 make supporting part 13 with
Tube 12 is concordant, you can takes out the detachable blind rivet from connecting in workpiece 3 to be connected.
It was found from foregoing description, compared to prior art, the detachable blind rivet of the application offer, by operating core bar 2,
Supporting part 13 is exerted a force, can deploy supporting part 13 to complete the fixation of workpiece 3 to be connected；Make its remote by operating core bar 2
From supporting part 13, supporting part 13 can recover shape when losing limitation, to realize dismounting；Recycling can be realized, is used
Cost is cheap.
In addition, installation and removal process without specific purpose tool, as long as can drive core bar 2 rotate general utility tool it is equal
Can, therefore, dismounting is more flexibly and convenient.
Refering to Fig. 4, specifically, the second end of the core bar 2, which is provided with, to be used to drive core bar 2 around the recessed of own axis
Groove 22, groove 22 are in-line or M shape, it is only necessary to which general screwdriver can be completed to dismount.

Screwed hole adaptation connection.The part of core bar 2 is threadedly coupled with stop part 11, is partly contained in tube 12, tube 12 it is interior
Footpath size is equal to or slightly greater than the outside dimension of core bar 2.
Certainly, this be both the application a specific embodiment, the core bar 2 of the application and the connection of blind rivet body part 1
Mode is not limited thereto, or other connected modes.For example, it is provided with other embodiment, in tube 12 interior
Screw thread, the outside of the core bar 2 are provided with the external screw thread being adapted to the internal thread.
In certain embodiments, the supporting part 13 includes some support bars 131 and the connection sheet that can be deformed upon
132, the connection sheet 132 is fixedly connected with tube 12, and the support bar 131 is fixed on the inner side of connection sheet 132.The core
The first end of bar 2 is the first arc surface 21；The first end of the support bar 131 is provided with inclined-plane, the tip on the inclined-plane be provided with
Second arc surface of the first arc surface 21 adaptation.
Certainly, this be only the application some specific embodiments, the shape and support bar 131 of the first end of core bar 2
The shape of one end is not limited to arc surface, or it can realize the shape of cooperation.
First arc surface 21 of core bar 2 acts on the second arc surface, and driving support bar 131 rotates around contact point, until with
Workpiece 3 to be connected is bonded.
Refering to Fig. 5, in certain embodiments, the support bar 131 includes integrally formed first plate and the second plate,
The section of support is L-shaped；When supporting part 13 deploys to be against the second side of workpiece 3 to be connected laterally, the first of support bar 131
Plate is bonded with the second side of workpiece 3 to be connected, and the second plate, which plays reinforcement effect, makes the second end of support bar 131 be not easy to stick up
Rise.
Certainly, this be only the application some specific embodiments, the shape of the support bar 131 of the application is not limited to
This, if with the preferable plastics of ductility or other materials, can also make other shapes.As long as tip and the core of support
Bar first end can match, and realize the expansion of supporting part.
Refering to Fig. 6, in certain embodiments, the support bar 131 has four, and four support bars 131 are equally
Annular spread, the second side uniform force of workpiece 3 to be connected can be ensured.Certainly, the quantity of support bar 131 is not limited to
This, or other quantity, but be preferred with being equally spaced.
In certain embodiments, the length of the core bar 2 meets following condition：Supporting part 13 deploys to be against the company for the treatment of laterally
When connecing the second side of workpiece 3, the second end of the core bar 2 is concordant with stop part 11 or is embedded in tube 12.It can ensure
The both sides of workpiece 3 to be connected are in concordant state, without significant protuberance, avoid second other portions of end scratch of core bar 2
Part.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, either which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.
