Detailed description of the invention
The utility model provides a kind of blanking plug arbitrarily, to solve the technical problem of the scratch stripper rubber that the diameter that is greater than tubing string due to the diameter of leather cup in prior art causes.
The utility model embodiment general thought is as follows:
Provide a kind of blanking plug arbitrarily, comprising: rope socket; Weighted lever, is connected to below rope socket; Top connection, is fixed on below weighted lever; Shear pin; Connecting rod, is connected to below top connection by shear pin by connecting rod; Upper connecting rod, is fixed on below connecting rod; Inner sleeve, is set in upper connecting rod, and is positioned at below connecting rod; Overcoat, is set in outside inner sleeve; Deck, is fixed on upper connecting rod, and is positioned at below inner sleeve; Slips, is sticked in outside deck; Lower contact, is sheathed on outside upper connecting rod; Adapter sleeve, is connected to lower contact; Jump ring, is arranged at adapter sleeve inwall; Lower link, is fixed on below adapter sleeve; Card tooth, is arranged at lower link outer wall and connects; Conehead, is fixed on bottom lower link; Leather cup, to be fixedly placed on lower link and to be positioned at above conehead; Bushing pipe, is fixed on lower link and is positioned at above leather cup; Sealing shroud, is fixed on outside bushing pipe and lower link.Wherein, bore into leather cup by conehead, and then leather cup is expanded, thus can shutoff tubing string, in this case, the diameter of leather cup can be less than the diameter of tubing string, thus reaches the technique effect preventing scratch stripper rubber, and it is higher that it is withstand voltage, thus can use in the high oil of strata pressure, gas well.
In order to better understand technique scheme, below by accompanying drawing and specific embodiment, technical solutions of the utility model are described in detail, the specific features being to be understood that in the utility model embodiment and embodiment is the detailed description to technical solutions of the utility model, instead of the restriction to technical solutions of the utility model, when not conflicting, the technical characteristic in the utility model embodiment and embodiment can combine mutually.
The utility model provides a kind of blanking plug arbitrarily, please refer to Fig. 1, comprising:
Rope socket 1;
Weighted lever 2, is connected to below rope socket 1;
Top connection 3, is fixed on below weighted lever 2;
Shear pin 4;
Connecting rod 5, is connected to below top connection 3 by shear pin 4 by connecting rod 5;
Upper connecting rod 8, is fixed on below connecting rod 5;
Inner sleeve 6, is set in upper connecting rod 8, and is positioned at below connecting rod 5;
Overcoat 7, is set in outside inner sleeve 6;
Deck 9, is fixed on upper connecting rod 8, and is positioned at below inner sleeve 6;
Slips 10, is sticked in outside deck 9;
Lower contact 11, is sheathed on outside upper connecting rod 8;
Adapter sleeve 12, is connected to lower contact 11;
Jump ring 13, is arranged at adapter sleeve 12 inwall;
Lower link 15, is fixed on below adapter sleeve 12;
