For reaching above-mentioned purpose, technical scheme is as follows:
A kind of perforation unit push rod loose joint, it is characterized in that: include the screw rod of the conical surface of front end, middle pedestal, rear end, extend back in the middle of the front end face of the described conical surface and be provided with blind hole, the axle of equilateral triangle it is provided with in blind hole, the width at equilateral triangle angle is 3-6mm, the side of the conical surface is uniformly provided with 3 guidees, lock pin it is provided with in guide, the wall thickness height 1-3mm of the aspect ratio conical surface of described lock pin, pedestal side is provided with T-slot, being provided with the mounting hole of strip in T-slot, driving lever stretches in mounting hole and is connected with axle, and the front end face of the conical surface is bolted end cap.
As a modification of the present invention, the number of described lock pin is identical with the limit number of axle.
As a modification of the present invention, being provided with horizontal groove in described mounting hole, locking plate is enclosed within driving lever, is stuck in described groove.
As a modification of the present invention, described driving lever is provided with aperture, and split pin is inserted in aperture.
As a modification of the present invention, described split pin is safety pin type split pin.
As a modification of the present invention, the head of described lock pin is semicircle.
As a modification of the present invention, the height of head of described driving lever is lower than pedestal cylindrical, higher than mounting hole outer surface.
The invention has the beneficial effects as follows:
A kind of perforation unit push rod loose joint of the present invention, owing to realizing top and the push rod loose joint locking more than 2, it is possible to better ensure the axiality of top and push rod loose joint, thus better ensureing the wall thickness accuracy of steel pipe；Burr is produced between top and loose joint, it is to avoid the situation of the dismounting difficulty that top is likely to occur owing to avoiding；When top produces, caudal peduncle need not be installed again, the substantial amounts of material consumption decreased, simplify top manufacturing procedure；Top manufacturing cost can be substantially reduced；Decrease the consumption as consumable accessory setting circle pin and split pin；The locking to top and release can be realized owing to a driving lever only need to be stirred, simplify the execute-in-place action of workman, improve the raising of production efficiency and alleviate the labor intensity of workman.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, it is further elucidated with the present invention, it should be understood that following detailed description of the invention is merely to illustrate the present invention rather than restriction the scope of the present invention.It should be noted that the word "front", "rear" of middle use is described below, direction that "left", "right", "up" and "down" refer in accompanying drawing, word " interior " and " outward " refer respectively to the direction towards or away from particular elements geometric center.
As shown in the figure, a kind of perforation unit push rod loose joint of the present invention, the conical surface 11 including front end, middle pedestal 8, the screw rod 10 of rear end, extend back in the middle of the front end face of the described conical surface 11 and be provided with blind hole, the axle 7 of equilateral triangle it is provided with in blind hole, the width at equilateral triangle angle is 3-6mm, the side of the conical surface 11 is uniformly provided with 3 guidees 4, lock pin 3 it is provided with in guide 4, the wall thickness height 1-3mm of the aspect ratio conical surface 11 of described lock pin 3, pedestal 8 side is provided with T-slot 13, the mounting hole 14 of strip it is provided with in T-slot 13, driving lever 5 stretches in mounting hole 14 and is connected with axle 7, the front end face of the conical surface 11 connects end cap 2 by bolt 1.
During use, top endoporus and push rod loose joint of the present invention adopt cone to be connected, and are arranged symmetrically with the lock pin 3 that three (or more) can be movable on the conical surface 11 of push rod loose joint, lock pin 3 is when locking position, lock pin 3 is stuck in the cannelure on the inner conical surface of top, it is ensured that top is fixing with loose joint relative position, it is achieved the locking of top, wherein the number of lock pin 3 is identical with the limit number of axle 7, axle 7 is triangle, and lock pin 3 is 3, and axle 7 is pentagon, lock pin 3 is 5, by that analogy.
Stir driving lever 5 band moving axis 7 and can rotate to an angle (60 ° is best angle), the cross section that axle 7 contacts with bearing pin 3 is approximate equilateral triangle (or approximate regular polygon), there is one fixed width at equilateral triangle angle, when bearing pin 3 contacts with the angle (one section of circular arc) of the equilateral triangle (or regular polygon) on the cross section of axle 7, bearing pin 3 is biased toward outer movement, is in locking position；When the limit of bearing pin 3 with the equilateral triangle (or regular polygon) on the cross section of axle 7 contacts, bearing pin 3 can move inward, and its end face can lower than the loose joint conical surface, it is achieved the release to top locking.
For preventing because impact causes driving lever 5 to rotate, cause bearing pin 3 to move, lose locking effect, when driving lever 5 is in locking position, it is provided with horizontal groove 15 in mounting hole 14, centre is bored foraminate locking plate 6 and is enclosed within driving lever 5 by aperture, it is stuck in the groove 15 of loose joint, it is ensured that driving lever 5 will not rotate；It is inserted into safety pin type split pin 9 at the aperture of driving lever 5, it is prevented that locking plate 6 gets loose simultaneously.
During due to top work, there are violent impact and motion, for ensureing stablizing of structure, reaching anti-loosing effect, what adopt between driving lever 5 with axle 7 is the structure of a kind of similar Tenon, the head of wherein said lock pin 3 is semicircle, being easy to clamping, the height of head of driving lever 5 is lower than pedestal 8 cylindrical, higher than mounting hole 14 outer surface, can either freely stir, pedestal 8 surface will not be protruded again and hurt sb.'s feelings.
Perforation unit push rod loose joint of the present invention, owing to realizing top and the push rod loose joint locking more than 2, it is possible to better ensure the axiality of top and push rod loose joint, thus better ensureing the wall thickness accuracy of steel pipe；Burr is produced between top and loose joint, it is to avoid the situation of the dismounting difficulty that top is likely to occur owing to avoiding；When top produces, caudal peduncle need not be installed again, the substantial amounts of material consumption decreased, simplify top manufacturing procedure；Top manufacturing cost can be substantially reduced；Decrease the consumption as consumable accessory setting circle pin and split pin；The locking to top and release can be realized owing to a driving lever only need to be stirred, simplify the execute-in-place action of workman, improve the raising of production efficiency and alleviate the labor intensity of workman.
