Abstract
The utility model relates to a tongue-locking anti-theft horse head pin for an oil pumping unit. A lock cylinder blind hole is arranged at the central position of a horse head pin main body, one side of the lower portion of the horse head pin main body is provided with a lock tongue hole communicated with the lock cylinder blind hole, a lock tongue is mounted into the lock tongue hole, a resetting spring and a lock tongue guiding ring are sleeved on the lock tongue, a lock cylinder with an eccentric head is arranged in the lock cylinder blind hole in a threaded connection mode, and the lower portion of the lock cylinder is cone-shaped. By using the anti-theft horse head pin, the problem that the horse head pin is stolen in the using process in a field is solved, namely burglary prevention is achieved, tipping and turning over of the oil pumping unit caused by the burglary are avoided, the normal operation of the oil pumping unit working in the field is ensured, and accordingly the oil extraction production efficiency and the oil well yield are improved effectively. The tongue-locking anti-theft horse head pin has the advantages of being reasonable in structural design, convenient to use, safe, reliable, strong in anti-theft function and the like.
Description
Technical field
The utility model belongs to pumping unit accessory technical field, particularly is applicable to a kind of pumping unit tongue locking antitheft horse head pin of beam pumping unit.
Background technique
In known exploitation technology, oil producing operation is a large amount of, and what use is beam pumping unit, is to be connected through four horse head pins between its walking beam and the horse head; And the existing used horse head pin of beam pumping unit is the solid cylindrical structure, adopts card edge type to connect during use, has no locking device; Because pumping unit is operation in the open air, therefore, thief is easy to the horse head pin is stolen; A pumping unit is stolen 2-3 horse head pin when serious, causes pumping unit to be drawn and turns over, and not only causes the damage of pumping unit; Pumping unit can't normally be moved, and have potential safety hazard, rate and oil well yield when also having had a strong impact on oil pumping simultaneously.
The model utility content
The purpose of the utility model provides good, the safe and reliable pumping unit tongue locking antitheft horse head pin of a kind of theftproof performance property.
The technological scheme that the purpose of realization the utility model is taked is: this antitheft horse head pin has a horse head pin main body; The center portion of horse head pin main body is provided with the lock core blind hole, and bottom one side of horse head pin main body is provided with the lock-tongue hole that is communicated with the lock core blind hole, and dead bolt is housed in the lock-tongue hole; Be set with Returnning spring and dead bolt lead ring on the dead bolt; In the lock core blind hole, through the lock core of the eccentric head of band that is threaded, the bottom of lock core is cone-shaped.
The front end of said dead bolt is cone-shaped, and its conical surface contacts with the conical surface of lock core bottom cone.
The corresponding side with lock-tongue hole of said horse head pin lower body part is provided with the weep hole that is communicated with the lock core blind hole.
The eccentric head of said lock core is gone up the supporting opener that is provided with eccentric groove.
The pumping unit tongue of processing according to such scheme locks antitheft horse head pin; Can effectively solve in the using process in the open air of horse head pin stolen; Promptly realized antitheft; Avoided the stolen pumping unit that causes to draw again and turned over damage, guaranteed that pumping unit works in the open air normal operation, thereby rate and oil well output when effectively having improved oil recovery.Advantages such as compared with prior art, this horse head pin has reasonable in design, and is easy to use, safe and reliable, that anti-theft feature property is strong.
Description of drawings

Fig. 2 is the structural representation of the utility model opening state.
Embodiment
Referring to Fig. 1, Fig. 2, the pumping unit tongue of the utility model locking antitheft horse head pin, this antitheft horse head pin has a horse head pin main body 1; The center portion of horse head pin main body 1 is provided with lock core blind hole 8, and horse head pin main body 1 bottom one side is provided with the lock-tongue hole 4 that is communicated with lock core blind hole 8, in lock core blind hole 8; Lock core 2 through the eccentric head of band that is threaded; The bottom of lock core 2 is cone-shaped, and dead bolt 6 is housed in the lock-tongue hole 4, is set with Returnning spring 7 and dead bolt lead ring 5 on the dead bolt 6.The front end of said dead bolt 6 is cone-shaped, and its conical surface contacts with the conical surface of lock core 2 bottom cones.Bottom in horse head pin main body 1 is provided with the weep hole 3 that is communicated with lock core blind hole 8 with lock-tongue hole 4 corresponding sides.The eccentric head of said lock core 2 is gone up the supporting opener 9 that is provided with eccentric groove, and label 10 is horse head pin suspension ring holes.
This horse head pin in use; With the endoporus of the opener of being with eccentric opening 9 insertion horse head pin main bodys 1, the more eccentric groove of opener 9 and the eccentric head of precession lock core 2 are aligned dextrorotation opener 9; Then it is descending to promote lock core 2; In lock core 2 descending processes, the cone face of its bottom promotes the cone face of dead bolt 6 along 5 Horizontal displacements of dead bolt lead ring, finally reaches to the lock state (see figure 1).Lock core 2 and horse head pin main body 1 are to realize precession and withdraw from through screw thread, and weep hole 3 is provided with in order to discharge rainwater.Otherwise derotation opener 9 makes lock core 2 reach top dead center then, and Returnning spring 7 discharges through original energy stored dead bolt 6 is pushed into the opening state (see figure 2), can easily the horse head pin be taken down.This horse head pin can overcome the drawback that conventional beam-pumping unit horse head pin exists fully, has promptly realized antitheft, and the pumping unit of having avoided again therefore causing draws and turns over damage.
