Abstract
The utility model relates to a kind of rock core and embraces the jump ring of taking, and comprises the jump ring body of tubular construction, and described jump ring body is by coil sheet around forming, and its side is with clearance groove; The sidewall spiral of described jump ring body is with multiple jack, the inclined of the relative jump ring body of described jack is arranged to its lower end, be plugged with respectively in jack to embrace and get screw, the described armful of screw pole getting screw is arranged with head of screw relative tilt, and the end symmetric of screw pole is with armful getting groove.The utility model adopts to embrace and gets screw and be connected with the detachable of jump ring body, conveniently changes separately armful getting screw, and compare traditional jump ring integral replacing, its cost reduces greatly; Embrace and get the groove that jump ring inwall compared by screw, it is large to the frictional force of rock core, improves and embraces power taking and efficiency.
Description
Technical field
The utility model relates to geological prospecting apparatus field, particularly relates to rig.
Background technology
Rig is requisite equipment in geological prospecting, and rig, when drilling through rock core, utilizes jump ring to be embraced from underground by rock core and takes out.Existing jump ring is closed loop configuration and with certain tapering, the inwall of jump ring is provided with many grooves; During work, rock core to be embraced by the frictional force between its inwall and rock core and is got by jump ring, the shortcoming of this jump ring be to comparatively soft rock core to embrace power taking not enough, rock core easily comes off, and needs repeatedly to embrace that get could success, cause inefficiency; Jump ring uses the groove serious wear of its inwall after a period of time, is not easy to repair it, and must change whole jump ring, its replacement cost is higher.
Utility model content
The applicant embraces for existing rock core the above-mentioned shortcoming that the jump ring of taking exists, and carries out studying and improving, provide a kind of operating efficiency high, embrace power taking foot, the rock core being convenient to repair embraces the jump ring of taking.
The technical scheme that the utility model adopts is as follows:
Rock core embraces a jump ring of taking, and comprises the jump ring body of tubular construction, and described jump ring body is by coil sheet around forming, and its side is with clearance groove; The sidewall spiral of described jump ring body is with multiple jack, the inclined of the relative jump ring body of described jack is arranged to its lower end, be plugged with respectively in jack to embrace and get screw, the described armful of screw pole getting screw is arranged with head of screw relative tilt, and the end symmetric of screw pole is with armful getting groove.
Further improvement as technique scheme:
The central axis of described jack relative to jump ring body central axis between angle equal relative to the angle of slope between head of screw with screw pole.
The beneficial effects of the utility model are as follows:
The utility model adopts to embrace and gets screw and be connected with the detachable of jump ring body, conveniently changes separately armful getting screw, and compare traditional jump ring integral replacing, its cost reduces greatly; Embrace and get the groove that jump ring inwall compared by screw, it is large to the frictional force of rock core, improves and embraces power taking and efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figures 1 to 4, the rock core of the present embodiment embraces the jump ring of taking, and comprises the jump ring body 1 of tubular construction, jump ring body 1 by coil sheet around forming, its side is with clearance groove 12, and clearance groove 12, for the elastic deformation of jump ring body 1 when embracing coring, improves armful power taking to rock core; The sidewall spiral of jump ring body 1 is with multiple jack 11, and the inclined of the relative jump ring body 1 of jack 11 is arranged to its lower end, is plugged with respectively to embrace and gets screw 2 in jack 11, embraces and gets between screw 2 with jump ring body 1 by be threaded or spot welding is connected.
As shown in Figure 5, embrace the screw pole 21 getting screw 2 and arrange with head of screw 22 relative tilt, the end symmetric of screw pole 21 gets groove 23 with embracing, and embraces the frictional force of getting between groove 23 and rock core.
The central axis of jack 11 relative to jump ring body 1 central axis between angle head of screw 22 relative to screw pole 21 between angle of slope equal, be typically provided between 30 ° to 45 °.
Get between screw 2 and jump ring body 1 for of the present utility model armful and be easy for installation and removal, be convenient to get screw change separately embracing, thus reduce replacement cost.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to spirit of the present utility model, the utility model can do any type of amendment.
