The technical solution adopted in the present invention is, steel pipe based on wedge shape self-locking pretension to clasp,
Including steel pipe socket part and steel pipe fastening part, steel pipe socket part includes steel cylinder, steel cylinder cylinder
Take on circumferentially arranged with shelves on inner tube wall in the middle part of body, the stack shell surface of steel cylinder is stamped with different thick
The annulus of degree, the stack shell of steel cylinder has opening, opening part joint steel pipe fastening part vertically；
Wherein steel pipe fastening part includes a pair symmetrically arranged pressing sheet, the one of every pressing sheet
The end face that limit is formed with steel cylinder upper shed wherein while being connected, the another side of every pressing sheet with
Butt strip vertically connects, and every pressing sheet has a pair circular hole, circle on two panels pressing sheet
The position in hole is identical, on two panels pressing sheet on two of which circular hole at non-co-located movable even
It is connected to wedge shape geosynclinal block.
The feature of the present invention also resides in,
Wherein wedge shape geosynclinal block is connected with circular hole by rivet, and rivet is by a pair through connection of pressing sheet.
Wherein wedge shape geosynclinal block can rotate around the central axis of circular hole.
Wherein the both sides of circular hole are provided with backing plate.
Its middle-grade shoulder is to be arranged on the arc convex within steel cylinder, and the quantity of shelves shoulder is more than 2.
The invention has the beneficial effects as follows, this fastener devises steel pipe socket part and steel pipe fastening portion
Point, use the auto-lock function constituting wedge shape geosynclinal block that coordinates between wedge shape geosynclinal block and rivet, at general
Docking steel pipe in pipe fitting sleeving part is locked, and completes the docking of steel pipe, easy and simple to handle and high
Effect, safety is higher simultaneously.This fastener is a single unit system simultaneously, is not separately provided
, the most there is not the problem that part is lost, it is simple to use and deposit in parts.Additionally, this dress
Put in the steel pipe of steel pipe socket part, be provided with shelves shoulder, prevent from clasp is moved on steel pipe,
Improve the reliability of device.

Detailed description of the invention
The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
Present invention steel pipe based on wedge shape self-locking pretension is to clasp, as shown in Figure 1, 2, and bag
Include steel pipe socket part and steel pipe fastening part.
Steel pipe socket part includes steel cylinder 7, and the inner tube wall in the middle part of steel cylinder 7 cylinder circumferentially sets
There are some grades of shoulders 6, the stack shell of steel cylinder 7 has opening 11 vertically, connect at opening 11
Steel pipe fastening part.
Shelves shoulder 6 is to be arranged on the arc convex within steel cylinder 7, and the quantity of shoulder block 6 is more than 2,
Can be higher with the pipe fitting reliability of socket in steel cylinder 7.
Steel pipe fastening part includes a pair symmetrically arranged pressing sheet 1, the one of every pressing sheet 1
Limit formed with steel cylinder 7 upper shed 11 section wherein while being connected, every pressing sheet 1 another
It is connected while vertical with butt strip 12, every pressing sheet 1 has a pair circular hole 2,
On two panels pressing sheet 1, the position of circular hole 2 is identical, on two panels pressing sheet 1 at non-co-located
Wedge shape geosynclinal block 4 it is connected with on two of which circular hole 2.
Wedge shape geosynclinal block 4 is connected on circular hole 2 by rivet 3, and rivet 3 is by a pair pressing sheet 1
Through connection, wedge shape geosynclinal block 4 can rotate around the central axis of circular hole 2.
Circular hole 2 be respectively provided on two sides with backing plate 8, wedge shape geosynclinal block 4 can be easy to and lock.
Rectangle chute 5 is had on wedge shape slotware 4.
It is stamped with the annulus of different-thickness on the stack shell of steel cylinder 7, so can strengthen steel cylinder 7
Intensity, prevents stress from concentrating.
The using method of clasp is, such as Fig. 3 by present invention steel pipe based on wedge shape self-locking pretension
Shown in, respectively steel pipe a9 and steel pipe b10 are inserted from two nozzles of steel cylinder 7, the two
The position of shoulder block 6 engages, and the wedge shape slotware 4 being in lax shape is revolved turnback (rivet
It is lax shape and the wedge shape slotware 4 of wedge shape slotware 4 time bottom 3 inclined-planes being positioned at wedge shape slotware 4
Parallel with the plane of pressing sheet 1), enforce wedge shape slotware 4, wedge shape slotware 4 utilizes long
Square chute 5 slides along rivet 3, and now, the distance between two panels butt strip 12 is gradually
Reduce, compaction process steel pipe docking after has been done step-by-step, along with rivet 3 moves to wedge-shaped slot
During the higher position of part 4, two panels butt strip 12 is close to bonding state, finally, steel pipe a9 with
Steel pipe b10 is fastened in steel cylinder 7, completes docking and the locking of steel pipe, additionally, due to
After the inclined-plane that wedge shape slotware 4 is formed and rivet 3 mating reaction, there is good auto-lock function, because of
This is possible to prevent wedge shape slotware 4 to slip, it is to avoid produce danger.
Present invention steel pipe based on wedge shape self-locking pretension, to clasp, uses unique wedge shape self-locking
Structure, easy and simple to handle, can effectively prevent fastener from disengaging with steel pipe, safety is high.Meanwhile, originally
Fastener can by steel plate after punching press, bending one-body molded, manufacturing procedure is few, is simple to manufacture,
Save part material.
