Abstract
The utility model provides a valve hand wheel lock nut disassembly tool. The tool comprises a fixed jaw of an L-shaped strip structure, one end of the fixed jaw is a wedge-shaped hook, the lower side of the other end of the fixed jaw is provided with a rectangular counter bored hole, a movable jaw is arranged in the rectangular counter bored hole of the fixed jaw, one end of the movable jaw is a wedge-shaped hook, the other end of the movable jaw is arranged in an inner cavity of a rectangular hollow box of the fixed jaw, the top end face of the part, stretching into the fixed jaw, of the movable jaw is provided with a trapezoidal threaded hole in threaded connection with a lead screw, a smooth shaft of the lead screw is connected with a through hole of the fixed jaw through a nylon sleeve in a clearance fit mode, the part, stretching out of the fixed jaw, of the lead screw is in threaded connection with two nuts, and the shaft, provided with threads ended and connected with the nuts, of the lead screw is provided with a stress application hole. The tool has the advantages that a hand wheel lock nut can be rapidly disassembled or assembled, the movable jaw can be freely regulated according to the size of the valve hand wheel lock nut, and the tool saves time and labor, is high in disassembling and assembling speed, suitable for occasions with narrow space, high in use safety factor and convenient to carry.
Description
Technical field
The utility model relates to maintenance of valve specific purpose tool field, is specifically related to valve handle lock nut extracting tool.
Background technology
When valve needs repairing, first to open handwheel lock nut, handwheel lock nut is generally a sheet type and has four groove structures, because lock nut does not have the such structure of general hexagon nut, so be all after knocking and make it to become flexible with punching pin and hand hammer when general dismounting, dismantle with pipe vice, because lock nut height is very little, in the process of pipe vice clamping, easily come off, cause personal safety hidden danger, dismantle with said method, often cause lock nut to damage, the lock nut of old valve is toward up becoming rusty and cause dismantling unsuccessfully, place at narrow space is also not suitable for using said method, labour intensity is large and have a potential safety hazard.
Summary of the invention
The not easily detachable problem of lock nut, the utility model proposes valve handle lock nut extracting tool and addresses the above problem when solving maintenance of valve.
The technical solution of the utility model is: valve handle lock nut extracting tool comprises regular jaw, regular jaw is " L " shape list structure, " L " shape one end is wedge shape eave tile, other end below has rectangle counterbore, the rectangle counterbore of regular jaw is built-in with moving jaw, moving jaw is " L " shape list structure, " L " shape one end is wedge shape eave tile, the other end is placed in the rectangle hollow case inner chamber of regular jaw, moving jaw stretches into and on the top end face of regular jaw part, has trapezoidal thread hole and be connected with threads of lead screw, the trapezoidal thread latter end of leading screw is optical axis, between the optical axis of leading screw and the through hole of regular jaw, be connected by nylon jacket matched in clearance, optical axis reaches regular jaw outside through the through hole at regular jaw rectangle counterbore top, the part that leading screw stretches out regular jaw outside two nuts that are threaded, on the axle that leading screw attaching nut's screw thread finishes, have afterburning hole.
The wedge shape eave tile of moving jaw and regular jaw is right-angled trapezium shape, and the right angle extreme direction of two wedge shape eave tiles is contrary, and position is relative.
Described regular jaw has rectangle counterbore, and outer wall one side of counterbore thickness direction is extended a turret head.
The utlity model has following beneficial effect: use this instrument quick release or handwheel lock nut is installed, moving jaw can arbitrarily adjust according to Valve lock bonnet size, time saving and energy saving, dismounting, installation rate are fast, are applicable to the occasion of narrow space, use safety coefficient is high, feature easy to carry.
Brief description of the drawings
Accompanying drawing 1 is assembling schematic diagram of the present utility model;
Accompanying drawing 2 is lower views of accompanying drawing 1.
1-regular jaw in figure, the afterburning hole of 2-, 3-nut, 4-nylon jacket, 5-leading screw, 6-turret head, 7-moving jaw, 8-wedge shape eave tile.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By Fig. 1 in conjunction with shown in Fig. 2, valve handle lock nut extracting tool, comprise regular jaw 1, regular jaw 1 is " L " shape list structure, " L " shape one end is wedge shape eave tile 8, other end below has rectangle counterbore, the rectangle counterbore of regular jaw 1 is built-in with moving jaw 7, moving jaw 7 is " L " shape list structure, " L " shape one end is wedge shape eave tile 8, the other end is placed in the rectangle hollow case inner chamber of regular jaw 1, moving jaw 7 stretches into and on the top end face of regular jaw 1 part, has trapezoidal thread hole and be threaded with leading screw 5, the trapezoidal thread latter end of leading screw 5 is optical axis, between the through hole of optical axis and regular jaw 1, be connected by nylon jacket 4 matched in clearance, nylon jacket 4 plays lubrication, and that leading screw 5 is rotated is more flexible, the optical axis of leading screw 5 reaches regular jaw 1 outside through the through hole at regular jaw 1 rectangle counterbore top, the part that leading screw 5 stretches out regular jaw 1 outside two nuts 3 that are threaded, two mutual leading screws 5 that are tightened in the other direction of nuts 3, on the axle that leading screw 5 attaching nuts' 3 screw thread finishes, have afterburning hole 2, adjust jaw distance by inserting rod-shaped tool torsion leading screw 5.
Described regular jaw 1 has rectangle counterbore, and outer wall one side of counterbore thickness direction is extended a turret head 6, by using general utility tool to be enclosed within changeover valve handwheel lock nut extracting tool on turret head 6.
The wedge shape eave tile 8 of moving jaw 7 and regular jaw 1 is right-angled trapezium shape, and the right angle extreme direction of two wedge shape eave tiles 8 is contrary, and position is relative, in throw, the right angle end of wedge shape eave tile 8 stretches into the opening of lock nut, does not injure lock nut, and use instrument turns over when installation.
Use this instrument quick release or handwheel lock nut is installed, moving jaw can arbitrarily adjust according to Valve lock bonnet size, time saving and energy saving, and dismounting, installation rate are fast, is applicable to the occasion of narrow space, uses safety coefficient high, feature easy to carry.
