Abstract
The utility model relates to a snap spring on a drilling rig. The snap spring is characterized by comprising a main body in an annual structure with certain conicity, wherein a notch is formed in the side wall of the main body; a plurality of axial grooves are formed in the inner wall of the main body; annual teeth are uniformly distributed in the inner wall of the main body in the axial direction. The snap spring is simple in structure; the inner wall of the snap spring is arranged as the tooth structure, so that the clamping effect of a rock core by the snap spring is greatly improved, and the working efficiency is increased.
Description
Technical field
The utility model relates to geological prospecting apparatus field, relates in particular to rig.
Background technology
Rig is requisite equipment in geological prospecting, and rig, when drilling through rock core, utilizes jump ring that rock core is taken out from underground armful.Existing jump ring be sealing loop configuration and with certain tapering, the inwall of jump ring is provided with many grooves; During work, jump ring is embraced rock core to get by the frictional force between its inwall and rock core, and the shortcoming of this jump ring is armful power taking deficiency to comparatively soft rock core, and rock core easily comes off, and therefore needs repeatedly to embrace and gets ability success, causes inefficiency.
Utility model content
The above-mentioned shortcoming that the applicant exists for jump ring on existing rig, studies and improves, and provides that a kind of operating efficiency is high, the jump ring on the rig of embracing power taking foot.
The technical scheme that the utility model adopts is as follows:
A jump ring on rig, is characterized in that: comprise the body with the loop configuration of certain taper, the sidewall of described body has short slot, and the inwall of body has many axial notches; The inwall of described body is axially evenly equipped with annular tooth along body.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, and the inwall of jump ring is arranged to tooth-shape structure, has greatly improved jump ring embracing of rock core got to effect, has improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is main sectional view of the present utility model.
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
Fig. 3 is three-dimensional structure diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
See Fig. 1 to Fig. 3, the utility model comprises the body with the loop configuration of certain taper, and the sidewall of body has short slot 3, short slot 3 make body be not closed structure so that jump ring with certain elasticity; The inwall of body has many axial notches 1, and groove 1 is beneficial to jump ring and inserts in rock core; The inwall of body is axially evenly equipped with annular tooth 2 along body, and annular tooth 2 increases the frictional force between jump ring and rock core, thereby improve jump ring, embracing of rock core is got to effect.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to spirit of the present utility model in the situation that, the utility model can be done any type of modification.
Claims (1)
1. the jump ring on rig, is characterized in that: comprise the body with the loop configuration of certain taper, the sidewall of described body has short slot, and the inwall of body has many axial notches; The inwall of described body is axially evenly equipped with annular tooth along body.
