Abstract
The utility model relates to an elastic elliptical bolt to connect two pipe strings or other tubular components in constructions, for example, to connect inserted spiral drill rod. In prior art, most of the inserted spiral drill rod bolts are U-shaped, which has the disadvantages of loose and unreliable connection and difficulty in making holes on male and female joints for the U-shaped bolt; the elastic elliptical bolt of the utility model comprises a pin head (1), a pin rod (2) and a pin bottom (3); wherein, the cross section of the pin head (1) is round, and the cross section of the pin rod (2) and the pin bottom (3) are elliptical; an elastic notch (4) is arranged on the axial position of the pin rod (2) and the pin bottom (3); the male and the female of the two spiral drill rods are connected through the open/close of the elastic notch (4); the elastic elliptical bolt of the utility model has the advantages of self locking function, no easy rotation or falling, convenience and reliability for connection.
Description
Technical field
The utility model relates to a kind of elastic elliptic bolt that is used for connecting two endowels in engineering construction, is a kind of elastic elliptic bolt that connects the plug-in type auger stem specifically.
Technical background
In the prior art, the connected mode of plug-in type auger stem joint is that latch connects, pull out in order to prevent that this type of connected mode from feeding with rising at drilling tool that the tool joint splicing position separates in the process, adopted " U " shape pin connected mode at the axis direction that hangs down as for the grafting joint, but find in using at the scene that " U " shape pin has obscission, therefore connects not too reliable.Find difficulty of the corresponding pin hole processing on the male and female joint of " U " shape pin simultaneously in process of production.
Summary of the invention
The purpose of this utility model is to provide a kind of auto-lock function that has, reliable elastic elliptic bolt easy to connect.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of elastic elliptic bolt, its special character is: described latch is made of pin top 1, pin rod 2 and the pin ends 3 three part, the cross section on described pin top 1 is circular, and 3 cross section is oval at the bottom of pin rod 2 and the pin, and 3 axial location is provided with elasticity breach 4 at the bottom of pin rod 2 and pin.
Above-mentioned elasticity breach 4 is arranged on the major axis or the short-axis direction of pin rod non-circular cross-section, and major axis is than the big 0～5mm of minor axis.
The body diameter on above-mentioned pin top 1 is than the big 0～10mm of transverse of pin rod 2.
3 transverse is than the big 0～3mm of transverse of pin rod 2 at the bottom of the above-mentioned pin.
3 ellipse short shaft is than the big 0～3mm of ellipse short shaft of pin rod 2 at the bottom of the above-mentioned pin.
The material of above-mentioned elastic elliptic bolt adopts the high-quality spring steel material.
Experimental result shows that the utility model with respect to the beneficial effect of prior art is: have auto-lock function when connecting auger stem, latch is difficult for rotating and coming off, and is easy to connect reliable.

The specific embodiment
Referring to Fig. 1, Fig. 2, it is located at the structural representation of the elastic elliptic bolt of transverse direction for breach; The utility model elastic elliptic bolt, it is divided into pin top 1, pin rod 2 and the pin ends 3 three part, at the bottom of pin rod 2 and pin 3 be axially arranged with the elasticity breach, the cross section on pin top 1 is circular, 3 cross section is oval at the bottom of pin rod 2 and the pin, breach is located at the long axis of ellipse direction, and major axis is than the big 0～5mm of minor axis, and the folding by latch elasticity breach links together the male and female joint of two auger stems.
The body diameter on pin top 1 is than the big 0～10mm of transverse of pin rod 2; The transverse at the pin end 3 is than the big 0～3mm of transverse of pin rod 2; The ellipse short shaft at the pin end 3 is than the big 0～3mm of ellipse short shaft of pin rod 2.3 big end blocks latch at the bottom of pin top 1 and the pin, prevents that it from doing axial float.The elliptic cross-section of pin rod 2 matches with slotted eye on the auger stem joint, prevents that latch from rotating.
The utility model selects for use the high-quality spring steel material to make, and through special heat treatment, improves the bulk strength of elasticity connecting pin.
Referring to Fig. 3, Fig. 4, it is located at the structural representation of the elastic elliptic bolt of ellipse short shaft direction for breach.
Referring to Fig. 5, Fig. 6, it is the sectional view after the male and female joint assembling of elastic elliptic bolt and auger stem.When latch is installed, on the sectional view of pin rod 2 direction of elasticity breach must bear with drilling rod draw, the direction of pressure is consistent, to prevent causing the auger stem connection failure feeding, rise latch when pulling out drilling rod because the folding of elasticity breach is loosening and come off.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
