Abstract
The invention discloses a plug-in back-locking type shackle, which comprises a hanging ring and a locking bar; a passing hole is arranged on a front arm of the hanging ring, and a locking hole is arranged on a rear arm of the hanging ring; a through groove and a clamping groove are arranged on the inner wall of the locking hole and are staggered on the circuferential direction of the locking holes; the locking bar comprises a clamping head and a counter-force member, wherein the clamping head is capable of passing through the through hole and plugging in the clamping groove. According to the plug-in back-locking type shackle, By using the staggering arrangement of the through groove and the clamping groove and the assistance of the counter-force member, the plug-in back-locking type shackle can reliably lock the locking bar and the hanging ring of the shackle together by plugging and rotating; the plug-in back-locking type shackle has simple structure, convenience in operation and good connecting reliability; moreover, the working efficiency is improved, and the safety of working is ensured.
Description
Technical field
The present invention relates to ground exploration technology field, relate in particular to a kind of insertion and lock the formula shackle.
Background technique
At present in the ground exploratory works, the operation that lifts the exploration drilling rod is through realizing being connected wire rope between drilling rod and the power plant.The bared end of drilling rod is steel cable fixedly, and the movable end of power plant is fixedly connected another root wire rope, and two wire rope connect through shackle, realizes the purpose of power transmission.
Like Fig. 1, shown in Figure 2, existing shackle mainly comprises suspension ring 1 and locking bar 2, offers aperture of door 13 on the forearm 11 of suspension ring 1, and tapped hole 14 (tapped hole 14 can be a through hole, also can be to close aperture of door) is set on the postbrachium 12, and the end of locking bar 2 is provided with outside thread 21.Suspension ring 1 are fixed through the screwed mode with locking bar 2, and the screw-in time is longer.In the practice of construction operation, the operator is in order to practice thrift the engineering time, often only screws to get under several.This mode of operation can not guarantee the reliability of connection between suspension ring 1 and the locking bar 2, exists great potential safety hazard.In the exploration process, the phenomenon that causes drilling rod in the process of lifting, to come off owing to the upset operation of shackle often has generation, not only has influence on construction period and quality, this obscission entail dangers to operator's life safety also when serious.
Therefore, those skilled in the art be devoted to develop a kind of simple in structure, operate shackle easily.
Summary of the invention
Because the above-mentioned defective of existing technology, technical problem to be solved by this invention provides a kind of simple in structure, operation and inserts easily and lock the formula shackle.
For realizing above-mentioned purpose, the invention provides a kind of insertion and lock the formula shackle, comprise suspension ring and locking bar, offered aperture of door on the forearm of said suspension ring, offer lockhole on the postbrachium of said suspension ring; Offer a groove, a draw-in groove on the inwall of said lockhole; Said groove and said draw-in groove shift to install on the circumferencial direction of said lockhole; Said locking bar comprises and can pass through said groove and be plugged in the dop in the said draw-in groove, and counter-force parts.
Preferably, said counter-force parts comprise elastic component at least.
Preferably, said counter-force parts also comprise fixed dam and sideboard.
Preferably, said groove and the said draw-in groove 90 ° of settings that on the circumferencial direction of said lockhole, misplace.
Preferably, said groove and the said draw-in groove 180 ° of settings that on the circumferencial direction of said lockhole, misplace.
The invention has the beneficial effects as follows:
The formula shackle is locked in insertion of the present invention, utilizes shifting to install of groove and draw-in groove, and is aided with the counter-force parts; Only need one slotting one to revolve two actions, just can the locking bar and the suspension ring of shackle be locked together reliably, simple in structure; Operation is convenient; Connection reliability is good, has both improved working efficiency, has guaranteed the Security of operation again.
Below will combine accompanying drawing that the technique effect of design of the present invention, concrete structure and generation is described further, to understand the object of the invention, characteristic and effect fully.
Description of drawings
Fig. 1 is the decomposition texture schematic representation of a kind of shackle in the existing technology.
Fig. 2 is the composite structure schematic representation of shackle shown in Figure 1.
Fig. 3 is the decomposition texture schematic representation of the present invention's one specific embodiment.
Fig. 4 is that the A of suspension ring part among Fig. 3 is to structural representation.
Fig. 5 is the composite structure schematic representation of shackle shown in Figure 3.
Embodiment
Like Fig. 3, shown in Figure 4, formula shackle one specific embodiment is locked in insertion of the present invention, comprises suspension ring 1 and locking bar 2.Offer aperture of door 13 on the forearm 11 of suspension ring 1, offered lockhole 14 on the postbrachium 12 of suspension ring 1.
Offer a groove 15, a draw-in groove 16 on the inwall of lockhole 14.Groove 15 shifts to install on the circumferencial direction of lockhole 14 with draw-in groove 16, and particularly as in the present embodiment, 90 ° of settings misplace.
Groove 15 extends on the inwall of whole lockhole 14, supplies the dop 22 on the locking bar 2 to pass.Draw-in groove 16 only extends on the part of lockhole 14 inwalls.
Above-mentioned counter-force parts comprise an elastic component 23 (for example spring) at least, also comprise fixed dam 24 and sideboard 25.
Structural design between locking bar 2, fixed dam 24 and the sideboard 25 is mainly considered the convenience of processing technology and assembling.
In other embodiments, groove 15 also can misplace 180 ° on the circumferencial direction of lockhole 14 with draw-in groove 16 and be provided with, or misplaces other angles, does not influence enforcement of the present invention.
In some other embodiment, draw-in groove 16 also can be on the groove 15, along one on lockhole 15 circumferencial directions groove, does not illustrate among the present invention.
During use, as shown in Figure 5, dop 22 1 ends with locking bar 2 inserted aperture of door 13 earlier, and passed lockhole 14 through groove 16.Under this state, what the sideboard 25 on the locking bar 2 received forearm 11 pushes compression elastic piece 23.Then, with the locking bar half-twist, make dop 22 aim at draw-in groove 16.After this, because the opposition of elastic component 23, as long as the operator looses one's grip, the dop 22 of locking bar 2 promptly falls into draw-in groove 16 automatically, between suspension ring 1 and the locking bar 2 promptly by locked.
When opening shackle, only need reverse operating, postpone earlier to revolve again and draw, can suspension ring be separated with locking bar.
The formula shackle is locked in insertion of the present invention, utilizes shifting to install of groove and draw-in groove, and is aided with the counter-force parts; Only need one slotting one to revolve two actions, just can the locking bar and the suspension ring of shackle be locked together reliably, simple in structure; Operation is convenient; Connection reliability is good, has both improved working efficiency, has guaranteed the Security of operation again.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variation.Therefore, all technician in the art all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology through the available technological scheme of logical analysis, reasoning, or a limited experiment.
