Abstract
The invention discloses a pin shaft, which comprises a pin shaft body and a spring positioning post arranged on the pin shaft body, wherein a U-shaped groove is formed in the circumference surface of the pin shaft body; the spring positioning post comprises a compression rod and a clamping jaw; the compression rod is fixed on the end part of the pin shaft body; the clamping jaw is fixed at the bottom of the compression rod and passes through the U-shaped groove corresponding to the clamping claw; and the bottom of the pin shaft body is also provided with conical welding metal. By using the mode, the pin shaft has the advantages that a pin shaft spring positioning post is used; the pin shaft can be firstly clamped into an inner hole of a connecting product, so that the pin shaft is aligned with the center of an installing hole of a connecting part; the operation is simple and convenient; the positioning is accurate; the time and the labor are saved; meanwhile, the wear-resistant performance is high; and the pin shaft is particularly suitable to be used for connecting box cover equipment.
Description
Technical field
The present invention relates to fastening piece, particularly relate to a kind of bearing pin.
Background technique
Bearing pin is the fastening piece of a class standard, both can static state be fixedly connected with, and also can do relative motion with connected piece, be mainly used in the hinged place of two parts, forms chain connection.Bearing pin locks with cotter pin usually, reliable operation, convenient disassembly.
Bearing pin of the prior art, when positioning connection, need the center, hole first being aimed at two union pieces, then, in the press-in that slowly exerts a force, in force process, need its center to align with the center being connected product, otherwise there will be eccentric force, easily cause bearing pin to rupture, its operation is cumbersome, wastes time and energy.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of bearing pin, bearing pin spring retention posts is utilized can first to be sticked into by bearing pin at connection product endoporus, make it to align with the mounting hole center connecting part part, simple to operation, accurate positioning, time saving and energy saving, have higher wear resistance, the connection being particularly suitable for case lid equipment is used simultaneously.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of bearing pin, comprise pin body and be arranged on the spring retention posts in pin body, described pin body circumferential surface is provided with U-type groove, described spring retention posts comprises constrictor and claw, described constrictor is fixed on pin body end, and described claw to be fixed on bottom constrictor and through the U-type groove corresponded, to be also provided with taper weld metal bottom described pin body.
In the present invention's preferred embodiments, described pin body inside is provided with center hole, and the length of described center hole is 2/3rds of bearing pin.
In the present invention's preferred embodiments, described constrictor comprises fixed axle sleeve, Compress Spring and movable axis, described fixed axle sleeve be fixed on end part of pin shaft and with bearing pin concentric, described Compress Spring is sleeved on movable axis.
In the present invention's preferred embodiments, described U-type groove two ends are 15mm from pin body two ends distance.
In the present invention's preferred embodiments, described taper weld metal is Cuprum alloy.
The invention has the beneficial effects as follows: a kind of bearing pin of the present invention, bearing pin spring retention posts is utilized can first to be sticked into by bearing pin at connection product endoporus, make it to align with the mounting hole center connecting part part, simple to operation, accurate positioning, time saving and energy saving, have higher wear resistance, the connection being particularly suitable for case lid equipment is used simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of bearing pin one of the present invention preferred embodiment.
Embodiment
Be clearly and completely described to the technological scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of bearing pin, comprise pin body 1 and be arranged on the spring retention posts 2 in pin body, described pin body 1 circumferential surface is provided with U-type groove 1-1, described spring retention posts 2 comprises constrictor and claw 3, described constrictor is fixed on pin body 1 end, described claw 3 to be fixed on bottom constrictor and through the U-type groove 1-1 corresponded, to be also provided with taper weld metal 8 bottom described pin body.
Further, described pin body 1 inside is provided with center hole 7, and the length of described center hole 7 is 2/3rds of pin body 1.
Enter a cloth, described constrictor comprises fixed axle sleeve 4, Compress Spring 5 and movable axis 6, described fixed axle sleeve 4 be fixed on pin body 1 end and with pin body 1 concentric, described Compress Spring 5 is sleeved on movable axis 6.
In above-mentioned, described pin body 1 is when connecting, pin body is placed in the center hole of the first connected element, then activity compression axle 6, claw 3 bottom movable axis 6 moves up and down along U-type groove 1-1, by claw 3 be connected component hole wall and fix, bearing pin center is corrected with the center, hole being connected component, then applies external force and pin body press-in is connected in component.
Further, described U-type groove 1-1 two ends are 15mm from pin body 1 two ends distance.
Further, described taper weld metal 8 is Cuprum alloy, has the wear resistance of high strength, extends the working life of bearing pin.
The invention has the beneficial effects as follows: a kind of bearing pin of the present invention, bearing pin spring retention posts is utilized can first to be sticked into by bearing pin at connection product endoporus, make it to align with the mounting hole center connecting part part, simple to operation, accurate positioning, time saving and energy saving, have higher wear resistance, the connection being particularly suitable for case lid equipment is used simultaneously.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
