The radial blind holes of crossover sub main body.
As further improvement of the utility model, the block is bearing pin, crossover sub main body non-circular column structure
Inside be provided with one and intersect the perforation connected with radial blind holes, bearing pin is fixed and is inserted in the perforation, the proper perforated of bearing pin side wall with it is blind
Hole intersects the opening portion that interconnecting part is formed and reached in the concave part in sliding pin side wall.
As further improvement of the utility model, the concave part in the sliding pin side wall is a ring shape in sliding pin side wall
Groove structure.
As further improvement of the utility model, the concave part in the sliding pin side wall is distinguished along sliding pin axial direction two side
Form the arcwall face with bearing pin form fit.
As further improvement of the utility model, radial blind holes intersect with perforated vertical in the crossover sub main body,
And perforation is axially crossover sub main body radial direction.
As further improvement of the utility model, the non-circular column in the crossover sub main body is tetragonal prism, six
One kind in corner post.
As further improvement of the utility model, the sliding pin other end is provided with chamfering structure.
As further improvement of the utility model, the elastic component is spring.
The beneficial effects of the utility model are：The utility model by setting radial blind holes on crossover sub body,
Sliding pin is set in radial blind holes, and realizes that sliding pin slides axially the limitation of distance by bearing pin, the structure radial blind holes are straight hole,
It is easy to fabricate, at the same it is easy to assembly, and space is big in radial blind holes, is easy to use large scale elastic component, avoids it from making for a long time
With failure, and the overall construction intensity of this patent is big, and long-term use is not easy to damage, service life length, and manufacturing cost is low.

Embodiment
Embodiment：A kind of formula crossover sub of sliding pin 2, including crossover sub main body 1, sliding pin 2, block and elastic component 3, it is described
The one end of crossover sub main body 1 is provided with a radial blind holes 4 formed with non-circular column structure, the non-circular column structure side wall,
Elastic component 3 and the order of sliding pin 2 are in the radial blind holes 4 in the radial blind holes 4, the both ends point in the elastic telescopic direction of elastic component 3
Not elasticity tight against the bottom surface of radial blind holes 4 and the end surface of sliding pin 2, the other end of sliding pin 2 can stretch out the setting of the outside of radial blind holes 4 away from
From, the side wall of sliding pin 2 is provided with an axially extending concave part 5, and block is fixedly installed in the radial blind holes 4 of crossover sub main body 1,
The utility model elastic component 3 realizes sliding axially for sliding pin 2, realizes the spacing of the sliding distance of sliding pin 2 by block, passes through sliding pin 2
Stretch out radial blind holes 4 and be connected together with external member and realize that crossover sub is threaded off with external member by the retraction radial blind holes 4 of sliding pin 2 and divide
From the radial blind holes 4 in crossover sub main body 1 are straight hole, and convenient processing and manufacture, block is to the spacing firm, steady of sliding pin 2
Fixed, long-term use is not easy to damage, and the space of the structure radial blind holes 4 is big, can use the elastic component 3 of large-size, elasticity
Part 3 is long-term use of to be also not easy to fail.
The block is bearing pin 6, and the non-circular column structure of crossover sub main body 1 is interior to intersect company provided with one with radial blind holes 4
Logical perforation 7, bearing pin 6 are fixed and are inserted in the perforation 7, and the proper perforated 7 of the side wall of bearing pin 6 intersects opening for interconnecting part formation with blind hole
Oral area is reached in the concave part 5 in the side wall of sliding pin 2, and the utility model is initially charged with elastic component 3, is then placed in cunning in assembling
Pin 2, then bearing pin 6 is located in perforation 7 according to while sliding pin 2 with hand, easy to assembly, overall construction intensity is big,
Long-term use is hardly damaged.
Concave part 5 in the side wall of sliding pin 2 is a ring annular groove structure in the side wall of sliding pin 2, is easy to process and assembles,
It may not be circular groove structure, but an elongate configuration or some elongate configurations such as tooth-shape structure etc..
Concave part 5 in the side wall of sliding pin 2 forms the arc with the form fit of bearing pin 6 along 2 axial two side of sliding pin respectively
Shape face, arcwall face coordinates with bearing pin 6 to be contacted, and avoids that the generation of holding phenomenon occurs, it is ensured that and latch and the relative slip of sliding pin 2 are smooth,
Ensure sliding pin 2 smoothly retraction and stretching radial blind holes 4.
