Description
Technical field
The utility model belongs to fastener for connection technical field, refers in particular to a kind of simple ring-pressing tool.
Background technology
In existing market, ring-pressing tool mainly consists of two parts, and a part is the pedestal for fixing tube,
Another part is the annular wedge being rotatably installed on pedestal, is pressed pipe by way of being pressed downward annular wedge
It connects, but it is two semicircle shape structures that the shortcomings that this tool, which is two wedges, when pedestal crimps pipe in pipe
The distance of surface sliding is longer, is easy to be that pipe generates fold, causes pipeline to leak, in order to avoid the hair of such case
Raw, current way is to subtract the shrinkage of wedge seldom, in this way and the bonding strength of pipeline is caused to reduce, under reliability
Drop, the service life of pipeline are short.
Invention content
Defect present in for the above-mentioned prior art, the purpose of this utility model are to provide a kind of briquetting for pipe crimping
Slippage is small, the simple ring-pressing tool that service life is long and crimp quality reliability is high.
What the purpose of this utility model was realized in：
A kind of simple ring-pressing tool, including the two pressure pipe main bodys being oppositely arranged in left and right, described two pressure pipe main bodys pass through
Back-shaped connector links together, and the top of each pressure pipe main body is opposite to offer semi-circular jaw, each semi-ring
Guide groove is offered inside clamp mouth, several active modules are slidably fitted in the guide groove, each movable mold
It is connected by spring between block.
In the present invention, column-shaped projection is formed on the active module of a pressure pipe main body, corresponded
Active module on offer cylindrical groove compatible with column-shaped projection.
In the present invention, the pressure pipe main body and back-shaped connector offer mutual compatible mounting hole, described
Fixed pin is installed in mounting hole, offers annular groove respectively at the both ends of fixed pin, fixed pin is by annular groove
Snap ring pressure pipe main body and back-shaped connector are fixed.
In the present invention, it is the regular hexagon that a middle part is circular hole after described two pressure pipe main bodys are closed up.
In the present invention, the spring is volute spring.
In the present invention, the upper side and lower side of each active module offers movable convenient for active module
Sliding recess forms fixed lobe compatible with sliding recess on the madial wall of semi-circular jaw.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
1, it is crimped using multiple crimping modules in the utility model, when working condition, each module is slided with respect to steel pipe
The distance of shifting is all very short, greatly improves the quality and reliability of crimping, and the service life of pipe is made to greatly improve.
2, the utility model is crimped using multiple crimping modules, an external shape of the guarantee steel pipe of energy high degree
Violent deformation will not occur for shape.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the partial structurtes schematic diagram of the utility model；
Fig. 3 is another structure diagram of the utility model.
Meaning represented by figure label：1- pressure pipe main bodys；The back-shaped connectors of 2-；
3- semi-circular jaws；4- guide grooves；5- active modules；6- springs；7- column-shaped projections；
8- cylindrical grooves；9- sliding recess；10- fixed pins.
Specific implementation mode
The utility model is described further with specific embodiment below, as shown in Figs. 1-2.
A kind of simple ring-pressing tool, including the two pressure pipe main bodys 1 in left and right, two pressure pipe main bodys 1 are opposite to be configured, and two
A pressure pipe main body 1 is linked together by back-shaped connector 2, and described two pressure pipe main bodys 1 and back-shaped connector 2 offer mutually
Compatible mounting hole is equipped with fixed pin 10 in mounting hole, annular groove is offered on fixed pin 10, fixed pin 10 is by ring
Snap ring in connected in star is fixed, and the top of each pressure pipe main body 1 is opposite to offer semi-circular jaw 3, is conveniently applicable in
Guide groove 4 is offered inside round steel pipe, each semi-circular jaw 3, several work are slidably fitted in the guide groove 4
Dynamic model block 5 is each connected between the active module 5 by spring 6, a connection structure in this way, each movable mold
Block 5 is all very short with respect to the distance of steel pipe sliding, greatly improves the quality and reliability of crimping, keeps the service life of pipe big
It is big to improve.
Preferably, column-shaped projection 7 is formed on the active module 5 of one of them pressure pipe main body 1, it is corresponding
Cylindrical groove 8 compatible with column-shaped projection 7, the guarantor of the structure energy high degree of such design are offered on active module 5
An outer shape for demonstrate,proving steel pipe, will not occur violent deformation.
Preferably, it is the regular hexagon that a middle part is circular hole after described two pressure pipe main bodys 1 are closed up.
Preferably, the spring 6 is volute spring, and volute spring has the advantages that compressing area is small, and taper compression spring is minimum
Compressing area can rest in, size as spring wire line footpath；Its size can also be set according to the requirement of product；Also have
The characteristics of long lifespan, the year-on-year cylindrical pressure spring of taper compression spring, the service life, relatively lower meeting was longer, because volute spring is each
A pitch diameters are all different, there is the sky enough to telescopic spring, so the service life of volute spring can one in the spring
A bit.
In the present invention, the upper side and lower side of each active module 5 offers convenient for 5 activity of active module
Sliding recess 9, fixed lobe compatible with sliding recess 9 is formed on the madial wall of semi-circular jaw 3, works as movable mold
When block 5 slides in and out stretching, sliding recess 9 with active module 5 move outside, when reaching the edge of 9 side of sliding recess,
Fixed lobe is defined the position of active module 5, i.e., the jaw of ring-pressing tool is to utmostly.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
