Drawings

The present invention will be further described with reference to the accompanying drawings.

Fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is an enlarged schematic view of a point a in fig. 1.

The figures in the drawings represent:

1. the anti-spraying pipe comprises a blowout prevention pipe 2, a paraffin removal valve 3, a clamp 4, a pressure gauge 5, a nozzle sleeve 6, a left production valve 7, a sleeve flange 8, a Christmas tree bottom flange 9, a variable thread short section 10, an oil pipe four-way head 11, a box body 12, a box cover 13, a stop lever 14, a closing stop 15, an oil production pipe 16, an engaging wheel 17, a chain plate 18, an engaging wheel box 19, a limiting stop 20, a double-hole valve 21, a right production valve 22 and a variable diameter oil rod.

Detailed Description

The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

In the description of the present invention, it should be understood that the terms "front", "back", "left", "right", "up", "down", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 and 2, the utility model comprises an outer box body, a Christmas tree component arranged inside the outer box body and an anti-theft component arranged on the Christmas tree component, the outer box body is of an upper opening type and comprises a box cover 12, a box body 11 for containing and stop levers 13 arranged on the inner walls of two sides of the box body 11, the production tree subassembly include lubricator 1, with adopt flange joint's paraffin removal valve 2 between the lubricator 1, locate paraffin removal valve 2 below the clamp, locate the oil recovery pipe 15 of clamp 3 below, with the left production valve 6 that oil recovery pipe 15 connects, with the right production valve 21 that the left side production valve 6 symmetry set up, locate the diplopore valve 20 of oil recovery pipe 15 below, locate the production tree bottom flange 8 of diplopore valve 20 below, be used for the casing flange 7 of oil recovery pipe 15 protection and be fixed in reducing pipe device on the casing flange 7.

The reducer pipe device comprises a reducer oil rod 22, two oil pipe four-way heads 10 arranged on the reducer oil rod 22 and pressure gauge assemblies arranged on the oil pipe four-way heads, wherein the two oil pipe four-way heads 10 are respectively arranged at two ends of the reducer oil rod 22. The pressure gauge assembly comprises a variable thread nipple 9 and a pressure gauge 4 arranged on the variable diameter oil rod 22. The anti-theft component comprises a meshing wheel box 18, a meshing wheel 16 arranged in the meshing wheel box 18, a chain plate 17 matched with the meshing wheel 16 and a combined block 14 fixed on the chain plate 17.

The locking type is performed to activate the motor controlling the engaging wheel 16 since the engaging wheel 16 is fixed to the engaging wheel housing 18.
