Abstract
The utility model discloses a sand-blasting thread protector of a drilling tool connector, which is applied to protecting a screw thread of a drilling tool in the sand blasting process. The sand-blasting thread protector comprises a lining pipe, and the key technique thereof also comprises a rubber screw thread, and the rubber screw thread and the lining pipe are integrated. The sand-blasting thread protector of the drilling tool connector has convenient processing and manufacture, low manufacturing cost, good protecting performance and good popularization and use value.
Description
Technical field
The utility model relates to a kind of sandblast thread protector, and especially a kind of tool joint sandblast thread protector is used for the screw thread at sandblast process protection oil drilling tools joint, prevents that screw thread is damaged.
Background technology
To the oil drilling tools sandblast time, the screw thread at tool joint place is caused damage, must use the thread protector frock that it is protected in order to prevent.At present, the general thread protector frock that adopts is the iron thread protector, and iron thread protector protective value is relatively poor, damage than being easier to, and the processing and manufacturing of iron thread protector is cumbersome, need carry out machine and just can put in place, and need carry out modifier treatment to it, and cost of manufacture is higher; Reason owing to machining accuracy in the use of iron thread protector causes damage to the screw thread of tool joint easily, and protective value is bad.
The utility model content
The technical problems to be solved in the utility model provides a kind of improved tool joint sandblast thread protector, and its processing and fabricating is convenient, and protective value is good.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of tool joint sandblast thread protector, and it comprises internal lining pipe, and its key is also to comprise in the structure rubber screw thread, and rubber screw thread and internal lining pipe adopt integrative-structure.
Adopt the beneficial effect that technique scheme produced to be: this tool joint sandblast thread protector is put into internal lining pipe in the special mould, rubber is poured into the mould one-time cast-forming again, forms integrative-structure, and processing and fabricating is convenient, and cost of manufacture is low; The rubber screw thread is used for being connected with tool joint, owing to adopt the rubber material can reduce the damage of butt joint screw thread when these sandblast thread protector loading and unloading, has improved protective value, and internal lining pipe plays a protective role to rubber sheath, can improve its application life.
Description of drawings
Fig. 1 is the structural representation of this tool joint sandblast thread protector;
Fig. 2 is that this thread protector uses schematic diagram.
Wherein, 1, rubber screw thread; 2, internal lining pipe; 3, tool joint.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1, it is a kind of tool joint sandblast thread protector, comprises internal lining pipe 2, and its key is also to comprise in the structure rubber screw thread 1, and rubber screw thread 1 and internal lining pipe 2 adopt integrative-structure.This internal lining pipe adopts the steel internal lining pipe in the practice, and rubber adopts natural rubber, earlier the steel neck bush is put into moulding form during making, then natural rubber is poured into the moulding form one-time cast-forming, makes them form integral structure like this.This sandblast thread protector processing and fabricating is convenient, and cost of manufacture is low; The rubber screw thread is used for being connected with tool joint, owing to adopt the rubber material can reduce the damage of butt joint screw thread when these sandblast thread protector loading and unloading, has improved protective value, and internal lining pipe plays a protective role to rubber sheath, can improve its application life.
Flanged, the peripheral hardware screw thread of above-mentioned rubber screw thread one end.
Also can process screw thread on the steel internal lining pipe in the use, more durable with the integral structure that forms after the castable rubber moulding like this, effect is relatively good in the use.
Referring to accompanying drawing 2, during use this sandblast thread protector is threaded with tool joint, both can carry out blasting treatment.
Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Claims (2)
1. tool joint sandblast thread protector, it comprises internal lining pipe (2), it is characterized in that: also comprise a rubber screw thread (1), rubber screw thread (1) and internal lining pipe (2) adopt integrative-structure.
2. tool joint sandblast thread protector according to claim 1 is characterized in that flanged, the peripheral hardware screw thread of described rubber screw thread one end.
