Abstract
The utility model relates to a crow bar with an adjustable supporting point; the front end of the crow bar is provided with a flat plate head part; a changeable crutch is arranged between the front end of the crow bar and the flat plate head part; the flat plate head part is lower than the crow bar; a supporting sleeve is sheathed on the crow bar; the lower side of the supporting sleeve is fixed with the upper end of an adjusting screw rod to form integrity; the external screw thread of the adjusting screw rod is connected with internal screw thread of an adjusting nut; the lower end of the adjusting nut is fixed on a base; the flat plate head part is provided with an open slot; the tail part of the crow bar is sheathed with a stress application cylinder; the supporting point formed by the supporting sleeve, the adjusting screw rod, the adjusting nut and the base is integrated with the crow bar to form integrity; the adjusting screw rod and the adjusting nut can be adjusted, so that the height of the supporting point can be adjusted, and the position of the supporting sleeve on the crow bar also can be adjusted; therefore, the crow bar with the adjustable supporting point is convenient to use, applicable to disassembling and installing oil field equipment, convenient and rapid in operation and has high working efficiency, and the supporting point does not fall off the crow bar, so that no potential safety hazard exists, and the crow bar is remarkable in economic benefit and social benefit.
Description
Technical field
The utility model is the instrument that the mounting or dismounting oil field equipment is used, and is a kind of band adjustable fulcrum formula crowbar.
Background technology
The oil field equipment that has need move it with crowbar when dismounting and installation, though existing crowbar is simple, but it does not have the strong point, need seek the strong point during use at the scene could use, sometimes be not easy to search out the proper supporting point at the scene, it is wasted time and energy when prizing equipment, also strong point landing can appear, produce potential safety hazard, particularly when aloft work, the easier personal injury accident that causes, therefore, existing crowbar uses inconvenience when dismounting and installation oil field equipment, inefficiency uses dangerous.
Summary of the invention
The purpose of this utility model is a kind of band adjustable fulcrum formula crowbar of design, and is easy to operate, quick when the dismounting oil field equipment, and safety misadventure does not take place.
The purpose of this utility model is achieved in that the crowbar front end has dull and stereotyped head, there is a change to turn between crowbar front end and the dull and stereotyped head, dull and stereotyped head is lower than crowbar, supporting sleeve is sleeved on the crowbar, supporting sleeve downside and adjusting screw(rod) upper end are fixed into one, the outside thread of adjusting screw(rod) is connected with the negative thread of setting nut, and the setting nut lower end is fixed on the base, on the dull and stereotyped head open slot is arranged.
The afterburning tube of crowbar afterbody suit.
The beneficial effects of the utility model are: the strong point and crowbar that supporting sleeve, adjusting screw(rod), setting nut, base are formed are formed one, can regulate between adjusting screw(rod), the setting nut, the height of the strong point can be regulated, the position of supporting sleeve on crowbar also can be regulated, therefore, the utility model is easy to use, be suitable for oil field equipment dismounting and installation, and it is easy to operate, quick, high efficiency, can not come off between the strong point and the crowbar, not have potential safety hazard, have remarkable economic efficiency and social benefit.
Description of drawings
Fig. 1 is the assembly drowing of the utility model embodiment.
Fig. 2 is the birds-eye view of part 2 among Fig. 1.
Specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
As seen from the figure, crowbar 2 front ends have dull and stereotyped head 7, there is a change to turn between crowbar 2 front ends and the dull and stereotyped head 7, make dull and stereotyped head 7 be lower than crowbar 2, be convenient to install and use, supporting sleeve 1 is sleeved on the crowbar 2, supporting sleeve 1 can slide on crowbar 2, so that regulate the distance between the strong point and the dull and stereotyped head 7, make it produce the different power that prizes, supporting sleeve 1 downside and adjusting screw(rod) 4 upper ends are fixed into one, the outside thread of adjusting screw(rod) 4 is connected with the negative thread of setting nut 5, by rotating wherein one, can regulate strong point height, so that adapt to the requirement of different installation sites, setting nut 5 lower ends are fixed on the base 6, on the dull and stereotyped head 7 open slot 8 is arranged, can inject the bolt of attaching parts, be convenient to prize nut.The afterburning tube 3 of crowbar 2 afterbody suits can stretch its afterburning tube 3, increases to prize the power arm of force, crosses the labour-saving purpose.
Can add drag devices between supporting sleeve 1 and the crowbar 2, so that can the relative fixed position.Can add drag devices between crowbar 2 and the afterburning tube 3, so that can the relative fixed position.
