Abstract
The utility model discloses a self-locking insertion and pull pin suitable for frequent insertion and pull. The self-locking insertion and pull pin comprises a pin body (1), a self-locking spring (2), a cylinder (3), a baffle (4), a baffle pin (5) and a pin pull ring (6). The self-locking spring (2) and the cylinder (3) are arranged in concentric holes of the pin body (1), the baffle (4) is arranged in an open groove in the end portion of the pin body (1), and the baffle (4) is located in a manner that the baffle pin (5) penetrates through the pin body (1) and a baffle groove. Before a pin shaft is inserted into a connecting portion, the baffle (4) is rotated by 90 degrees around the baffle pin (5), and then the pin shaft can be inserted into the connecting portion or pulled out of the connecting portion. After the pin shaft is inserted into the connecting portion, the baffle (4) is reversely rotated by 90 degrees, and the position of the baffle (4) will not change under the effect of pressure of the self-locking spring (2). With the self-locking structure, the self-locking insertion and pull pin suitable for frequent insertion and pull is high in reliability, flexible in design and high in practicality in practical engineering.
Description
Technical field
The utility model relates to a kind of self-locking inserted pin, particularly a kind of self-locking inserted pin that is applicable to frequent plug.
Background technique
Pin is the indispensable part of articulated mechanism, thereby realizes relatively rotating between component.At present, be used in the shank of articulated mechanism mainly a rod jaw pin structural type to be arranged as main, in the nominal diameter end of shank, with cotter pin or back-up ring, carry out spacing.This structural type applies to while needing the dismounting position, and following shortcoming is arranged: at first, dismounting needs instrument, inconvenience, need to pull down cotter pin or back-up ring with needle-nose pliers or circlip pliers, then just can extract bearing pin; Secondly, easily cotter pin or back-up ring are damaged in unloading process, and the component of pulling down are easily lost; Finally, dismantle and install consuming time longer.
The model utility content
The purpose of this utility model is to provide a kind of self-locking inserted pin that is applicable to frequent plug, solves in plug inconvenience, unloading process and easily damages and long problem consuming time.
A kind of self-locking inserted pin that is applicable to frequent plug, comprising: shank also comprises: cylindrical body, self-locking spring, baffle plate, baffle plate pin and pin draw ring.
One end of shank is shaft shoulder structure, and there is circular port radially the end that shank has a shaft shoulder structure; There is concentric hole the center of the shank the other end, and shank has an end of concentric hole that the opening slot of flat is arranged vertically, and respectively there is a column pin hole opening slot both sides of flat.Self-locking spring, cylindrical body all are placed in the shank concentric hole, and an end face of self-locking spring contacts with shank concentric hole bottom surface, another end face of self-locking spring and cylindrical body end contact.One end of baffle plate is arc surface, and baffle plate has the arc-shaped guide rail groove near the middle part of arc surface, and baffle plate is placed in the shank opening slot, a side of baffle plate arc surface and cylindrical body end contact.The baffle plate pin passes baffle plate arc-shaped guide rail groove and with the column pin hole of shank, is fixedly connected with.The column part of pin draw ring is placed in the circular port at shank shaft shoulder place.
While maybe needing to extract from connection part before shank inserts connection part, first baffle plate is moved to an end of close baffle plate arc surface along its arc-shaped guide rail groove, because the guide-track groove of baffle plate is arcuate structure, in the baffle plate moving process, the side of baffle plate compression cylindrical body and self-locking spring move along the shaft axis of shank.Then, pull that end face away from arc shaped surface of baffle plate, make baffle plate rotate 90 degree around the baffle plate pin, length direction and the shank axis parallel of baffle plate, namely catch the pin draw ring that shank is inserted or extract connection part at this moment.After shank inserts connection part, baffle plate is rotated 90 degree, then baffle plate is moved to position away from the baffle plate arc shaped surface along its guide-track groove, this moment, self-locking spring was in stretched condition.If unmanned be operation, under the effect of the pressure of self-locking spring, the position of baffle plate can not change.
This self-locking inserted pin can realize in a short period of time that the pin joint position connects and dismounting, does not need extracting tool, and can be repeatedly used, and has reduced the activity duration, has greatly improved working efficiency.
Description of drawings
A kind of structural representation that is applicable to the self-locking inserted pin of frequent plug of Fig. 1.
1. shank 2. self-locking spring 3. cylindrical body 4. baffle plate 5. baffle plate pins 6. are sold draw rings.
Embodiment
A kind of self-locking inserted pin that is applicable to frequent plug, comprising: shank 1 also comprises: cylindrical body 3, self-locking spring 2, baffle plate 4, baffle plate pin 5 and pin draw ring 6.
One end of shank 1 is shaft shoulder structure, and there is radially circular port the end that shank 1 has shaft shoulder structure; There is concentric hole the center of shank 1 the other end, and shank 1 has an end of concentric hole that the opening slot of flat is arranged vertically, and respectively there is a column pin hole opening slot both sides of flat.Self-locking spring 2, cylindrical body 3 all are placed in shank 1 concentric hole, and an end face of self-locking spring 2 contacts with shank 1 concentric hole bottom surface, another end face of self-locking spring 2 and cylindrical body 3 end contacts.One end of baffle plate 4 is arc surface, and baffle plate 4 has the arc-shaped guide rail groove near the middle part of arc surface, and baffle plate 4 is placed in shank 1 opening slot, a side of baffle plate 4 arc surfaces and cylindrical body 3 end contacts.Baffle plate pin 5 passes baffle plate 4 arc-shaped guide rail grooves and with the column pin hole of shank 1, is fixedly connected with.The column part of pin draw ring 6 is placed in the circular port at shank 1 shaft shoulder place.
While maybe needing to extract from connection part before shank 1 inserts connection part, first baffle plate 4 is moved to an end of close baffle plate 4 arc surfaces along its guide-track groove, because the guide-track groove of baffle plate 4 is arcuate structure, in baffle plate 4 moving process, the side of baffle plate 4 compression cylindrical body 3 and self-locking spring 2 move along the shaft axis of shank 1.Then, pull the end face away from arc shaped surface of baffle plate 4, make baffle plate 4 rotate 90 degree around baffle plate pin 5, length direction and shank 1 axis parallel of baffle plate 4, namely catch pin draw ring 6 that shank 1 is inserted or extract connection part at this moment.After shank 1 inserts connection part, baffle plate 4 is rotated 90 degree, then baffle plate 4 is moved to position away from baffle plate 4 arc shaped surfaces along its guide-track groove, this moment, self-locking spring 2 was in stretched condition.If unmanned be operation, under the effect of the pressure of self-locking spring 2, the position of baffle plate 4 can not change.
