Abstract
The utility model relates to a locating pin comprising a pin head and a pin column. The pin head is fixedly connected with the pin column together, and the peripheral surface of the pin column is symmetrically provided with a first groove; the first groove extends towards the pin head and extends out of the pin head; the tail end of the first groove is radially provided with a second groove towards the inside of the pin column; an inserting block is inserted in the first groove; the inserting block is longer than the first groove; the second groove is internally provided with a rotary rotation block; a torsional spring is arranged between the rotation block and the sidewall of the second groove; the front end of the rotation block is provided with an anti-skid layer; and the outer end of the inserting block is provided with a pull ring. The locating pin provided by the utility model vibrates when a mechanical device operates normally, or vibrates when other mechanical devices vibrate excessively, and the locating pin is hard to taking off from locating holes of two parts, so that the working performances of the mechanical devices are excellent, and the stability of the work of the mechanical devices is improved.
Description
Technical field
The utility model relates to a kind of locating stud, particularly is a kind of difficult locating stud of from positioning hole, deviating from, and belongs to the device technology field that connection or fixed component or machine parts are used.
Background technique
In machinery, in the positioning hole of locating stud or the part that connects fastening, play the effect of the unrestricted motion degree of restriction object through needs.But, when the machinery normal operation, can produce vibration unavoidably; Also can produce vibration, and existing locating stud is generally straight pin, the design that has nothing spacing because other mechanical equipment vibration is excessive; When vibration was excessive, locating stud will produce loosening phenomenon, from positioning hole, deviates from; Thereby influence the service behaviour of machinery, reduced the stability of the work of machinery.
The model utility content
The utility model purpose is that a kind of difficult locating stud of from positioning hole, deviating from is provided for the deficiency that overcomes existing technology.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of locating stud, comprise pin head and pin, and said pin head and pin are fixed together, and on the outer peripheral surface of said pin this are provided with first groove; Said first groove extends and extends the pin head to pin head direction; The end of said first groove has second groove to the inner radial of pin; Be inserted with inserted block in said first groove; The length of said inserted block is greater than the length of first groove; Be provided with rotatable switch block in said second groove; Be provided with torsion spring between the sidewall of the said switch block and second groove.
Preferably, the front end of said switch block is provided with skid resistant course.
Preferably, the outer end of said inserted block is provided with draw ring.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The locating stud of the utility model is during use, after in the positioning hole of two parts of pin insertion; Inserted block is extracted in first groove, because the effect of torsion spring makes switch block rotate; Near the location hole wall, when the machinery normal operation, produce vibration, or produce when vibrating because other mechanical equipment vibration is excessive; Locating stud also is difficult in the positioning hole of two parts, deviating from, and the favorable working performance of machinery has increased the stability of the work of machinery.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the stereogram of the locating stud of the utility model;
Accompanying drawing 2 is the structural representation of the locating stud of the utility model;
Accompanying drawing 3 is the user mode structural representation of the locating stud of the utility model;
Wherein: 1, pin head; 2, pin; 3, first groove; 4, second groove; 5, inserted block; 6, draw ring; 7, switch block; 8, torsion spring; 9, skid resistant course; 10, two parts; 11, positioning hole.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Like accompanying drawing 1, the described a kind of locating stud of the utility model shown in 2, comprise pin head 1 and pin 2, said pin head 1 is fixed together with pin 2, on the outer peripheral surface of said pin 2 this is provided with first groove 3; Said first groove 3 extends and extends pin head 1 to pin head 1 direction; The end of said first groove 3 has second groove 4 to the inner radial of pin 2; Be inserted with inserted block 5 in said first groove 3; The length of said inserted block 5 is greater than the length of first groove 3; The outer end of said inserted block 5 is provided with draw ring 6; Be provided with rotatable switch block 7 in said second groove 4; Be provided with torsion spring 8 between the sidewall of the said switch block 7 and second groove 4; The front end of said switch block 7 is provided with skid resistant course 9.
The described a kind of locating stud of the utility model shown in accompanying drawing 3 during use, inserts inserted block 5 in first groove earlier; Make switch block 7 compression torsion springs 8 get in second groove 4, go into pin 2 in the positioning hole 11 of two parts 10 after, pull draw ring 6 inserted block 5 extracted in first groove 3; Because the reset response of torsion spring 8 makes switch block 7 rotate, near the wall of positioning hole 11; When the machinery normal operation, produce vibration, or produce when vibrating because other mechanical equipment vibration is excessive, locating stud also is difficult in the positioning hole 11 of two parts 10, deviating from; The favorable working performance of machinery has increased the stability of the work of machinery; Because the front end of switch block 7 is provided with skid resistant course 9, increased the friction of switch block 7 with the wall of positioning hole 11, make locating stud more can in the positioning hole 11 of two parts 10, not deviate from.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
