Abstract

Disclosed is a clamp spring which comprises a C-shaped clamp spring body and is characterized in that a conical surface is arranged on the lateral side of the clamp spring body, and an outer water flume is arranged on the outer conical surface; inner teeth are arranged on the inner side of the clamp spring body. The cone angle of the outer conical surface is 2-5 degrees. The outer water flume is a straight water flume or an inclined water flume with spiral angle less than 45 degrees; the depth of the outer water flume is 1.5-10mm; the inner teeth adopts annular teeth or spirally-continuous teeth; the tooth shape of the inner teeth includes conical, triangle, rectangle, trapezoid, circular arc-shaped or irregular shapes. The clamp spring has the technical effects that when rock core enters the clamp spring and enables the clamp spring to move upwards, the flushing liquid channel is completely opened through the outer water flume to ensure the flushing liquid to flow smoothly. The friction between rock core and clamp spring is increased when inner teeth are adopted for drilling, so the clamp spring is clamped with the rock core tightly, and the clamp core safety of the clamp spring is improved.

Description

A kind of jump ring

Technical field

The utility model relates to a kind of jump ring, and especially geological drilling single tube drill bit is cored with the structure of jump ring.

Background technology

What known geological drilling usually adopted with jump ring is that jump ring internal diameter position is provided with the bar groove, and the external diameter position is provided with the structure of tapering, and the single tube drill bit does not have the special use jump ring of coring, and all adopts the jump ring of said structure.Because single tube drill bit jump ring is installed on reamer or the drill bit, rock core will block passage of irrigation fluid when creeping into, and influence the unimpeded of flushing liquor, may cause that pump load increases the weight of, and perhaps flushing liquor is not smooth and cause the boring accident.

Summary of the invention

The purpose of this utility model just provides and a kind ofly can guarantee the jump ring structure that flushing liquor is unimpeded can allow single tube creep into the time, to solve the obstruction of rock core in the core-drilling of the single tube drill bit passage of irrigation fluid that prior art exists, influence the unimpeded of flushing liquor, may cause that pump load increases the weight of, perhaps flushing liquor is not smooth and cause the problem of boring accident.

Technical scheme of the present invention is: comprise the jump ring body of C shape, it is characterized in that: the outside at this jump ring body is provided with the conical surface, is provided with external flume on this male cone (strobilus masculinus); Be provided with interior tooth in the inboard of this jump ring body.

The cone angle of described male cone (strobilus masculinus) is 2-5 °.

Described external flume is straight tank or helical angle less than 45 ° oblique tank, and the degree of depth of this external flume is 1.5-10mm.

Tooth adopts annular tooth or the continuous tooth of spirality in described, and tooth form of tooth comprises taper, stage body shape, triangle, rectangle, trapezoidal, circular arc or irregularly shaped in this.

The tooth of tooth is apart from being 4-20mm in described, and depth of threat is 0.3-2mm, and tooth is wide to be 2-15mm.

The obtained technique effect of the utility model is:

1. enter jump ring and make when moving on the jump ring when rock core, fully open passage of irrigation fluid, guarantee the unimpeded of flushing liquor by external flume.

2. get the friction that increases when boring between rock core and the jump ring by interior tooth, guarantee jump ring chucking rock core, strengthen the card heart safety of jump ring.

The specific embodiment

Below in conjunction with accompanying drawing 1～Fig. 4, jump ring structure of the present utility model is illustrated:

The utility model comprises the jump ring body 1 of C shape, is provided with the conical surface 4 in the outside of this jump ring body 1, and the cone angle of this male cone (strobilus masculinus) 4 is 2-5 °, is provided with external flume 3 on this male cone (strobilus masculinus) 4.Described external flume 3 is straight tank (as Fig. 1～shown in Figure 3) or helical angle f less than 45 ° oblique tank (referring to dotted line among Fig. 1), and the degree of depth a of this external flume 3 is 1.5-10mm.

Tooth 7 in the inboard of this jump ring body 1 is provided with.Tooth 7 adopts annular tooth (as Fig. 1～shown in Figure 3) or the continuous tooth of spirality (not shown) in described, and tooth form of tooth 7 comprises taper, stage body shape, triangle, rectangle, trapezoidal, circular arc or irregularly shaped (referring to Fig. 4-1～Fig. 4-5) in this.

The depth of threat d of tooth 7 is 0.3-2mm in described, and tooth is 4-20mm apart from c, and the wide e of tooth is 2-15mm.

Describe the concrete structure and the effect of each several part below in detail:

Male cone (strobilus masculinus) 1: its effect be jump ring when gliding with rock core and drill bit or the reamer endoporus conical surface with matching produce relative motion, make jump ring hold rock core tightly, the cone angle of male cone (strobilus masculinus) is 2-5 °.

External flume 3: external flume 3 is a straight tank or less than the oblique tank of 45 ° of helical angles, normally used is straight tank, 15 °, 30 ° or 45 ° of oblique tanks.Wherein straight tank is convenient to processing, and the water flowing effect is better, and is the most general.The degree of depth a of external flume 3 typically refers to the degree of depth that the big end of jump ring (being the upper end of Fig. 1 and Fig. 2) is located, different and different according to the jump ring diameter, the thickness b of inner tooth part position, the depth d of tooth 7 and tank processing back in the numerical value of its degree of depth a is decided by, the thickness b of general inner tooth part position is 0.5-1.5mm.And the b value of regular size drill bit (75-110mm) is 0.8-1mm, then requires the b value greater than 1.5mm for diameter greater than the used jump ring of the drill bit of 150mm.According to the different size requirement, the big end tank of jump ring degree of depth a is generally 1.5-10mm, and the big end tank degree of depth a of the used jump ring of bit diameter (75-110mm) commonly used is 2-3mm.

Interior tooth 7: the effect of interior tooth 7 is the power of holding tightly that strengthens between jump ring and the rock core, interior tooth 7 is annular tooth or the continuous tooth of spiral, tooth form can be according to easy to process and the producer's hobby design, and tooth form commonly used has taper (Fig. 1), stage body shape (Fig. 4-1), triangle (Fig. 4-2), rectangle (Fig. 4-3), trapezoidal (Fig. 4-4), circular arc (Fig. 4-5) or other irregular thread forms.The depth d of interior tooth 7 is generally 0.3-2mm, and the d value of regular size (75-110mm) drill bit is 0.3-1mm; The width of interior tooth 7 is generally 2-15mm, and regular size (75-110mm) drill bit is 2-5mm; The interior sound of baby talk is generally 4-20mm apart from c, and regular size (75-110mm) drill bit is 5-8mm.
