Description of drawings
Fig. 1 is the utility model structural representation.
Specific embodiments
The utility model is not subjected to the restriction of following enforcement example, can determine specific embodiment according to the technical solution of the utility model mode of occupation.
Below in conjunction with accompanying drawing the utility model is described in further details.
As shown in Figure 1, the utility model mainly is made up of upper joint sleeve 1, body 2, sliding sleeve 3, shear pin 4, ball seat 5 and lower contact 6, and upper joint sleeve 1 lower end has external screw thread to be connected with body 2 front end internal threads; Body 2 front middle parts leave side opening; Two grooves are arranged in the middle of body 2 inner chambers, sliding sleeve 3 is enclosed within the body 2, its have one with the suitable boss of body 2 grooves, and along boss its excess-three face cut-in groove except that front end, sliding sleeve 3 appearances and the formation of body 2 inner chambers are slidingly matched; Ball seat 5 is fixed in the sliding sleeve 3 by shear pin 4; Lower contact 6 front ends have screw thread to be connected with body 2, and lower contact 6 front inner wall thickness are greater than sliding sleeve 3 lower end inner wall thickness, and the internal diameter of sliding sleeve 3 front portions is more than or equal to lower contact 6 internal diameters.
Can be according to actual needs, to above-mentioned a kind of bypass sliding sleeve further optimization and/or improvements:
Upper joint sleeve 1 external screw thread terminal has dovetail groove, is the inclined-plane of angle less than 45 degree at the bottom of the groove, and general angle is better less than 30 degree, and body 2 front ends and this groove are suitable; Lower contact 6 front end screw thread terminals also have groove identical with upper joint sleeve 1 and that direction is opposite, and body 2 lower ends and this groove are suitable.
For the ease of sliding sleeve 3 descending and location, require body 2 lumen channels to be shaped as the angle of the angle on groove front end inclined-plane greater than its inclined-plane, groove lower end.
Ball seat 5 front end inner chambers are taper seat, can be suitable with steel ball.
Upper joint sleeve 1 front end has internal thread to be convenient to connect.
