Abstract
The utility model discloses a cam screw mounting structure of adjustable blanking plug, it includes casing (5) of adjustable blanking plug, is equipped with cam (2) in casing (5), is equipped with in casing (5) and hangs a section of thick bamboo (1), and the hole on hanging a section of thick bamboo (1) aligns with the centre bore of cam (2), and screw (3) and screw (4) pass earlier and hang a section of thick bamboo (1) and insert in the centre bore of cam (2) again. The utility model discloses can bear most external force by hanging a section of thick bamboo, reduce the influence of salvaging the impact force to relevant screw thread on screw, cam and the casing, improve the life-span of salvaging of adjustable blanking plug. Therefore, compared with the prior art, the utility model has the advantages of simple structure, less influence by the throwing and dragging operation and longer service life.
Description
Technical field
The utility model relates to a kind of cam screw mounting structure of adjustable blanking plug, belongs to the eccentric water injection well in oil field with adjustable blanking plug technical field.
Background technology
Along with eccentric water injection well is more and more with the kind of adjustable blanking plug, the life problems of blanking plug begins to be subjected to more and more people's concern.In order to realize regulatory function, existing adjustable blanking plug can not resemble and adopt the axis of rotation of an axis as cam traditional blanking plug, and can only be with the screw of two cantilever constructions axis of rotation as cam.Because size restrictions, the connecting thread between screw and the housing is too short.In the pulling process, because cam is stressed, the screw thread distortion very easily takes place, the fault that cam is stuck causes blanking plug to be scrapped.
Summary of the invention
The purpose of this utility model is: provide a kind of pulling operating influence that is subjected to less, improve the cam screw mounting structure of the adjustable blanking plug in pulling life-span, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises the housing of adjustable blanking plug, is provided with cam in housing, is provided with cup in housing, aligns with the centre bore of cam in the hole on the cup, and screw passes earlier in the centre bore that cup is inserted in cam again.
The cam screw mounting structure of above-mentioned adjustable blanking plug is provided with stepped hole in housing, be provided with limited step on cup.
The utility model can bear most of external force by cup, has reduced and has salvaged the influence of impact force to associated threads on screw, cam and the housing, the pulling life-span of having improved adjustable blanking plug.Therefore compare with prior art, the utlity model has simple in structure, be subjected to the pulling operating influence less, improve the advantage in pulling life-span.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is a vertical view of the present utility model.
The specific embodiment
Embodiment of the present utility model: at first in housing 5, process stepped hole 7, in will packing housing 5 together with the torsionspring 6 that is placed on the side into from left end with the cup 1 of limited step 8 then, to the limited step 8 of cup 1 with till the end face of stepped holes 7 in the housing 5 contacts.After manufacturing screwed hole and thread Pilot hole on housing 5 and the cup 1, cam 2 is packed into from the notch of housing 5 sides, be stuck in the gap of cup 1.The hole of screw 3 and screw 4 being passed cup 1 earlier is inserted in the centre bore of cam 2 again, and housing 5, cup 1, cam 2 are fixed together.The breach that arm passes cup 1 side of turning round with torsionspring 6 hangs on the cam 2 again.By the assembly method of existing adjustable blanking plug other parts being installed at last gets final product.
Claims (2)
1. the cam screw mounting structure of an adjustable blanking plug, it comprises the housing (5) of adjustable blanking plug, in housing (5), be provided with cam (2), it is characterized in that: in housing (5), be provided with cup (1), align with the centre bore of cam (2) in hole on the cup (1), screw (3) and screw (4) pass cup (1) earlier and be inserted in the centre bore of cam (2) again.
2. the cam screw mounting structure of adjustable blanking plug according to claim 1 is characterized in that: be provided with stepped hole (7) in housing (5), be provided with limited step (8) on cup (1).
