Abstract

The utility model provides an elastic self-locking pin, comprising a lock pin. The elastic self-locking pin is characterized in that two guide plates are arranged in parallel; the upper edge and the lower edge of the guide plate are fixed through two lateral plates, forming a pane; the two lateral plates are vertically fixed with the lateral surface of the sheathed section bar; a section of the fixing end extends outside. A certain space is maintained between the guide plate adjacent to the lateral surface of the sheathed section bar and the lateral surface of the sheathed section bar. A lock pin jack is arranged on the same position in the middle of each of the two guide plate. The jacks of the two guide plates and the through holes of the two locked sheathed section bars have the same axial line. The lock pin is inserted into the jacks of two guide plates. A compressed spring is sheathed with the lock pin between the two guide plates. One end of the compressed spring abuts with one guide plate. The other end of the compressed spring abuts with a clip spring fixed on the lock pin. One end of the lock pin is provided with a semi-circle or a circular pull ring. The other end of the lock pin is the insertion locating end. The lock pin can be automatically pressed in the two sheathed section bar lockout holes under the acting force of the elastic force as the locking function. The utility model has the advantages of convenient operations, accurate and rapid lock pin location and no easy lost.

Description

The elasticity self-lock pin

Technical field

The utility model belongs to the mechanism with the section bar locking mutual alignment of two sockets, is a kind of elasticity self-lock pin specifically.

Background technique

The section bar that often runs into two different bores in practice sets with each other, and uses these two section bars of a horizontal string of pin then, so that with the situation of the mutual alignment of two section bars locking.Present way is that pin bar and section bar itself two separates mostly, and pin is not only lost easily, and also difficulty relatively when sealing in section bar.

Summary of the invention

The purpose of this utility model is the deficiency that exists at prior art, and a kind of elasticity self-lock pin is provided, and can make lock pin be pressed into the section bar locking aperture of two sockets automatically under the elastic force active force, to play the effect of locking, easy to operate, the lock pin accurate positioning is rapid, and is difficult for losing.

The purpose of this utility model is achieved by the following technical solution: a kind of elasticity self-lock pin, comprise lock pin, it is characterized in that having two guide plates to be arranged in parallel, following on two guide plates by the fixing square frame that forms of two blocks of side plates, two blocks of side plates and socket section bar outer side surface vertical fixing end stretch out one section, make guide plate and socket section bar outer side surface keep a determining deviation near socket section bar outer side surface, same area in the middle of two guide plates is respectively opened a lock pin jack, the through hole of the jack of two guide plates and locked two socket section bars is same axis, lock pin inserts the jack of two guide plates, on the lock pin between two guide plates, be with a stage clip, stage clip one end withstands on the guide plate, and the other end withstands on the jump ring fixing on the lock pin.

Described lock pin one end is provided with semicircle or circular draw ring, and the other end is for inserting positioning end.

Have one on the described lock pin and embed mouth, jump ring is stuck in the embedding ingress.

The utility model compared with prior art has many advantages and good effect:

1, the utility model is easy to operate, and the lock pin accurate positioning is rapid, and is difficult for losing.

2, the utility model is simple in structure, and is easy to make, and cost is lower, of many uses.

Embodiment

Referring to Fig. 1-Fig. 4, a kind of elasticity self-lock pin mainly is made up of with parallel symmetrically arranged two guide plates 1,2 lock pin 3.Bottom forms square frame by 7 welding of two blocks of side plates or riveted fixing on two guide plates 1,2, and two blocks of side plates 7 stretch out one section with socket section bar 8 outer side surface vertical fixing ends.Same area in the middle of two guide plates 1,2 is respectively opened a lock pin jack, the jack of two guide plates 1,2 is same axis, lock pin 3 inserts the jack of two guide plates 1,2, on the lock pin 3 between two guide plates 1,2, be with a stage clip 6, have one on the lock pin 3 and embed mouth, have a jump ring 5 to be stuck in the embedding ingress.Stage clip 6 one ends withstand on the guide plate 1, and the other end withstands on the jump ring 5 fixing on the lock pin 3.

When installing and using, two side plate 7 sections of stretching out are vertical with heavy caliber socket section bar 8 outer side surfaces and be fixed as one by welding, make the guide plate 2 near socket section bar 8 outer side surfaces keep a determining deviation with socket section bar 8 outer side surfaces.Be provided with on heavy caliber section bar 8 and through hole 10, the hole periphery is straight; The small-bore section bar 9 that inserts in the heavy caliber section bar 8 is provided with through hole 11, and through hole 11 curves inwardly, to play the effect of lock pin 3 automatic capturing positions.The through hole 10,11 of the jack of two guide plates 1,2 and locked two socket section bars 8,9 is same axis.

The working principle of elasticity self-lock pin:

Entangle finger ring 4 with finger in use and be pulled outwardly lock pin 3, till lock pin 3 breaks away from heavy caliber section bar 8, because guide plate 2 has a gap apart from heavy caliber section bar 8 outer walls, thereby the danger of having avoided lock pin 3 to pull.The small-bore section bar 9 of push-and-pull is to change the relative position of itself and heavy caliber section bar 8, loosen lock pin 3 then, lock pin 3 is under the active force of stage clip 6, lock pin 3 front ends enter a side through hole 10 of heavy caliber section bar 8 and withstand on the outer wall of small-bore section bar 9, continue the small-bore section bar 9 of push-and-pull, automatically fall into the through hole 11 that small-bore section bar 9 caves in until lock pin 3, the relative position of the big small-bore section bar 8,9 of lock pin 3 lockings.Another benefit with the spacing stage clip 5 of jump ring is to change stage clip 5 at any time.

Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
