Abstract
The invention relates to a shackle with a pin shaft thread anti-rotation structure. The shackle comprises a shackle body and a pin shaft, wherein the shackle body is a U-shaped ring; spherical heads are arranged at the two ends of the shackle body; pin holes are formed in the spherical heads; a thread is formed in the inner wall of one pin hole; the inner wall of the other pin hole is smooth; the pin shaft is inserted in the pin hole with the smooth inner wall and is in threaded connection with the pin hole with the thread. The shackle is characterized in that an arc groove is formed in the outer side surface of the spherical head on which the pin hole with the smooth inner wall is formed; a detachable clamping buckle is mounted at the head end of the pin shaft; when the pin shaft is mounted in the pin holes in the shackle body, the clamping buckle is mounted at the head end of the pin shaft, and a clamp of the clamping buckle is correspondingly clamped in the arc groove in the outer side surface of the spherical head to limit the rotation of the pin shaft. The shackle is ingenious in structure, reasonable in design, convenient to assemble and firm to connect, can be used for preventing the loosening of the thread caused by the rotation of the pin shaft and avoiding the falling of the pin shaft, and is improved in safety.
Description
Technical field
The present invention relates to a kind of link, specifically a kind of shackle with pin shaft thread anti-rotation structure, belongs to hoisting and handling equipment technical field.
Background technology
Shackle is instrument common on hanging device, usually and hanging belt, rope rig, chain etc. with the use of.Shackle of the prior art arranges pin-and-hole by clevis eye two ends usually, and pin-and-hole connects a bearing pin and forms.The top of clevis eye and pin respectively as a coupling end, for connecting miscellaneous part.Such shackle often occurs that bearing pin rotates, and causes thread looseness in actual use, thus shackle bearing pin may be caused to come off, and causes safety misadventure.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of shackle with pin shaft thread anti-rotation structure, its structure is ingenious, reasonable in design, easy to assembly, be connected firmly, can prevent bearing pin from rotating and the thread looseness that causes, avoid bearing pin to come off, improve shackle safety.
According to technical scheme provided by the invention: the shackle with pin shaft thread anti-rotation structure, comprise shackle body and bearing pin, described shackle body is a clevis eye, the two ends of shackle body are provided with bulb, pin-and-hole is processed with in bulb, one of them pin-and-hole inwall is processed with screw thread, another pin-and-hole inner wall smooth; Described bearing pin inserts rear thread by inner wall smooth pin-and-hole and is connected in threaded pin-and-hole; It is characterized in that: the bulb lateral surface at described inner wall smooth pin-and-hole place is processed with arc groove, described bearing pin head end is provided with detouchable buckle, when bearing pin loads in the pin-and-hole on shackle body, buckle is arranged on bearing pin head end, the clamp correspondence of buckle snaps in the arc groove on bulb lateral surface, and restriction bearing pin rotates.
As a further improvement on the present invention, the arc groove on the bulb lateral surface at described inner wall smooth pin-and-hole place has two, these two arc grooves be 180 ° symmetrical; Clamp on described buckle also has two, and two clamps are also symmetrical in 180 °.
As a further improvement on the present invention, described bearing pin head end end face is provided with a radial through groove, and described buckle is provided with a fixed strip, and described fixed strip is used for correspondence and is installed in radial through groove and is bolted fixing.
compared with prior art, advantage is in the present invention:structure of the present invention is ingenious, reasonable in design, easy to assembly, is connected firmly, and can prevent bearing pin from rotating and the thread looseness that causes, avoid bearing pin to come off, improve shackle safety.

Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Fig. 1 ~ Fig. 4: the shackle with pin shaft thread anti-rotation structure in embodiment mainly comprises shackle body 1 and bearing pin 2, described shackle body 1 is a clevis eye, the two ends of shackle body 1 are provided with bulb 3, pin-and-hole is processed with in bulb 3, one of them pin-and-hole inwall is processed with screw thread, another pin-and-hole inner wall smooth; Described bearing pin 2 inserts rear thread by inner wall smooth pin-and-hole and is connected in threaded pin-and-hole; Bulb 3 lateral surface at described inner wall smooth pin-and-hole place is processed with arc groove 5, described bearing pin 2 head end is provided with detouchable buckle 4, when bearing pin 2 loads in the pin-and-hole on shackle body 1, buckle 4 is arranged on bearing pin 2 head end, clamp 6 correspondence of buckle 4 snaps in the arc groove 5 on bulb 3 lateral surface, and restriction bearing pin 2 rotates.
As shown in Fig. 1 ~ Fig. 4, in the embodiment of the present invention, the arc groove 5 on bulb 3 lateral surface at described inner wall smooth pin-and-hole place has two, and these two arc grooves 5 are symmetrical in 180 °; Clamp 6 on described buckle 4 also has two, and two clamps 6 are also symmetrical in 180 °.
As shown in Fig. 1 ~ Fig. 4, in the embodiment of the present invention, described bearing pin 2 head end end face is provided with a radial through groove, and described buckle 4 is provided with a fixed strip, and described fixed strip is used for correspondence and is installed in radial through groove and is connected and fixed by bolt 7.
During embody rule, first bearing pin 2 is threaded with the pin-and-hole on shackle body 1 and tightens, then fix in corresponding for the fixed strip on the buckle 4 through groove of radial direction being installed on bearing pin 2 head end with socket bolt 7, clamp 6 correspondence of buckle 4 snaps in the arc groove 5 on bulb 3 lateral surface, prevents the screw thread caused because bearing pin 2 rotates from getting loose.The present invention, compared with common negative thread shackle, can prevent from unloading the thread looseness being buckled in and causing because of various factors in routine use process, and prevent bearing pin 2 from getting loose, safety factor is high, and make simple, cost is relatively not high, and client is more acceptant.
