Description

Small space union fastener

Technical field

The present invention is applied to the installation and fastening of pipeline connecting parts union in small space, is that a kind of pipe union is tight It is fixedly mounted with and sets.

Background technique

Currently, China's industry and civilian pipe union fastening tool are mainly pipe vice and spanner etc., these tradition are tight Gu tool length is longer, using handle as lever, to do circular-rotation as fulcrum with union nut contact point, handle is longer, Required space is bigger, and by taking main fastening tool pipe vice as an example, handle is longer, and tool part fit clearance is larger, required space At least twice or more distance of union diameter；These conventional tools there are certain requirements space locating for pipe union, right In the installation and fastening of union in some small spaces, existing conventional tool is unable to satisfy requirement, and union is widely used in The connection of industry and life pipeline, locating special case is complicated, needs one kind to adapt to union in small space and fastens work Tool.

Summary of the invention:

A kind of loose joint is provided in order to solve installation and fastening difficult problem, the utility model of union in small space Head fastener, the fastener can fasten union in small space, and convenient for operation, provide to install and fastening union Reliable tool reduces pipeline caused by loosening because of union convenient for the Fast Installation and fastening of the union in small space Sewing for interior gas or liquid, prevents the generation of accident and problem.

Technical solution:

Small space union fastener mainly includes clamp, gear, gear shaft, shell, ratchet spanner, bearing, fastener It is rectangle body structure, gear shaft crosses shell, and two sides shaft end stretches out in hull outside, and gear shaft is fixed on shell by bearing Internal middle front part, ratchet spanner are mounted on gear shaft shaft end, and gear is fixed on gear shaft, clamp be stuck in left and right shell it Between, clamp one end and engaged gears, the other end closely can mutually block with union, can move along clamp round slide；Press ratchet After spanner, one-way clearance movement is passed into clamp by gear shaft and gear, clamp rotation drives union nut mobile, real Fasten to existing union；The first end of U-shaped card be straight-tooth, other end bayonet be it is U-shaped, union nut outer surface, U can be directly clamped among The model of type clamp can be divided into 1/2 inch, 3/4 inch, 1 inch, 1.2 inches, 1.5 inches.

For the difference of small space size locating for union, two kinds of modes of operation are determined, when down space is distinguished in loose joint When greater than 10mm, when using U-shaped card head, clamp is directly stuck in union nut surface, since U-shaped card head will wrap up loose joint Five faces in eight contact surfaces of head nut, are stuck in nut closely in U-shaped card head, press ratchet spanner, passed by gear Dynamic, U-shaped card head drives nut, achievees the purpose that fasten union, for convenient for operation, fastener rear end is equipped with handle；It is this Fastening means is convenient and efficient, and U-shaped card head can be divided into the models such as 1/2 inch, 3/4 inch, 1 inch, 1.2 inches, 1.5 inches, It can be fastened according to loose joint area of bed by replacing different model U-shaped card head.

When down space is respectively smaller than 10mm in loose joint, when using V-type clamp, fastening will be used in shell two sides fastening hook Bar or rocking bar are fastened to union cloud cluster and flush, and drive V-type clamp to be pressed to union nut outer surface, press ratchet wrench Hand is fastened, and achievees the purpose that union fastens；V-type clamp opening angle is 135 degree, with loose joint nut octagon interior angle Angle is consistent, and when fastening is closely connected with loose joint, and to increase frictional force, V-type clamp contact surface vehicle has screw die.

Both mode of operation shell, gear, ratchet spanneres etc. have versatility, the space size according to locating for union Replace U-shaped or V-type clamp and installation V-type clamp clamp device；To meet gear shaft rotation flexibly, axis both ends are equipped with zanjon 608-2Z ball bearing；To meet intensity requirement, gear, gear shaft and clamp carry out modifier treatment to it, and surface is quenched.

Since ratchet spanner can be mobile in small space, ratchet straps moving gear, gear is harmonious with clamp to be engaged, and clamp exists Under the positioning of shell circular arc, power and movement are conveyed and are delivered on union nut by clamp, achieve the purpose that union fastens, real The fastening of union in existing small space.

Detailed description of the invention:

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

Fig. 1 is the small space union fastener scheme of erection using U-shaped card head, and specific name is 1 ratchet spanner, and 2 is left Shell, 3 right shell bodies, 4 gears, 5 bearings, 6 hubcaps, 7U type clamp, 8 positioning pins, 9 handle bases, 10 gear shafts, hexagonal in 11 Fixed link, 12 handle base fixing bolts, 13 handles.

Fig. 2 is the small space union fastener scheme of erection using V-type clamp, and specific name is 1 ratchet spanner, and 2 is tight Gu hook, 3 clamp handles, 4 left shells, 5V type clamp, 6 right shell bodies, 7 gears, 8 bearings, 9 hubcaps, 10 positioning pins, 11 whirlpool rulers, 12 fastening seats, 13 anchorage bars, 14 worm screws, 15 gear shafts, hexagonal fixed link in 16,17 backing plates.
