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 bearing pin screw thread anti-rotation structure, belong to the hoisting and handling equipment technical field.
Background technology
Shackle is instrument common on hanging device, usually and hanging belt, rope rig, chain etc. be used in conjunction with.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 are respectively as a coupling end, for connecting miscellaneous part.Such shackle often occurs that bearing pin rotates in actual use, causes thread looseness, thereby may cause the shackle bearing pin 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, a kind of shackle with bearing pin screw thread anti-rotation structure is provided, its structure is ingenious, reasonable in design, easy to assembly, be connected firmly, the thread looseness that can prevent bearing pin from rotating and cause, avoid bearing pin to come off, and improves the shackle safety.
According to technical scheme provided by the invention: the shackle with bearing pin screw thread anti-rotation structure, comprise shackle body and bearing pin, described shackle body is a clevis eye, two ends at shackle body are provided with bulb, be processed with pin-and-hole 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 the inner wall smooth pin-and-hole and is connected in threaded pin-and-hole; It is characterized in that: on the bulb lateral surface at described inner wall smooth pin-and-hole place, be processed with arc groove, described bearing pin head end is equipped with the detouchable buckle, in the time of in pin-and-hole on bearing pin is packed shackle body into, buckle is arranged on the bearing pin head end, the clamp correspondence of buckle snaps in the arc groove on the bulb lateral surface, and the 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, two clamps also be 180 ° symmetrical.
As a further improvement on the present invention, described bearing pin head end end face is provided with one and radially connects groove, and described buckle is provided with a fixed strip, and described fixed strip is installed on and radially connects in groove and be bolted fixing for correspondence.
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 that bearing pin from rotating and the thread looseness that causes avoids bearing pin to come off, and improves the shackle safety.
The accompanying drawing explanation
Fig. 1 is the structural front view that the embodiment of the present invention has the shackle of bearing pin screw thread anti-rotation structure.
Fig. 2 is the structure left view that the embodiment of the present invention has the shackle of bearing pin screw thread anti-rotation structure.
Fig. 3 is the structure upward view that the embodiment of the present invention has the shackle of bearing pin screw thread anti-rotation structure.
Fig. 4 is the three-dimensional structure diagram that the embodiment of the present invention has the shackle of bearing pin screw thread anti-rotation structure.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Fig. 1 ~ Fig. 4: the shackle with bearing pin screw thread anti-rotation structure in embodiment mainly comprises shackle body 1 and bearing pin 2, described shackle body 1 is a clevis eye, be provided with bulb 3 at the two ends of shackle body 1, be processed with pin-and-hole 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 the inner wall smooth pin-and-hole and is connected in threaded pin-and-hole; Be processed with arc groove 5 on bulb 3 lateral surfaces at described inner wall smooth pin-and-hole place, described bearing pin 2 head ends are equipped with detouchable buckle 4, in the time of in pin-and-hole on bearing pin 2 is packed shackle body 1 into, buckle 4 is arranged on bearing pin 2 head ends, clamp 6 correspondences of buckle 4 snap in the arc groove 5 on bulb 3 lateral surfaces, 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 surfaces at described inner wall smooth pin-and-hole place has two, these two arc grooves 5 be 180 ° symmetrical; Clamp 6 on described buckle 4 also has two, two clamps 6 also be 180 ° symmetrical.
As shown in Fig. 1 ~ Fig. 4, in the embodiment of the present invention, described bearing pin 2 head end end faces are provided with one and radially connect groove, and described buckle 4 is provided with a fixed strip, and described fixed strip is installed on and radially connects in groove and be connected and fixed by bolt 7 for correspondence.
During concrete application, at first bearing pin 2 is threaded and tightens with pin-and-hole on shackle body 1, then the fixed strip correspondence on buckle 4 is installed in the radially perforation groove of bearing pin 2 head ends fixing with socket bolt 7, clamp 6 correspondences of buckle 4 snap in the arc groove 5 on bulb 3 lateral surfaces, prevent from getting loose because bearing pin 2 rotates the screw thread caused.The present invention compares with common negative thread shackle, can prevent from unloading being buckled in the thread looseness caused because of various factors in the routine use process, prevents that bearing pin 2 from getting loose, and safety factor is high, makes simply, and cost is relatively not high, and the client is more acceptant.
