Description
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.

Specific embodiment
When down space is respectively greater than 10mm on union, according to loose joint area of bed, 7U type card in required Fig. 1 is selected
Head is installed on fastener, and clamp is stuck in union nut surface, continuous to press 1 ratchet spanner in Fig. 1, ratchet wrench up and down
10 gear shafts in hand-motion Fig. 1, gear shaft rotate 4 gears in band Fig. 1,7U type clamp in engaged gears Fig. 1, and U-shaped card head drives
Union nut along the circumferential direction moves, when clamp is run to can not mutually be engaged with gear or clamp connects with surrounding objects and touches
When, it can not continue to move to, fastener is removed from union, adjust U-shaped card head position, be stuck on union nut again,
Ratchet spanner is pressed, is fastened repeatedly again, fastening purpose is reached, after general union loosens, operating 1-2 times can make to live
Connector reaches fastening.
When down space is respectively smaller than 10mm in loose joint, using V-type clamp, 5V type clamp in Fig. 2 is installed to fastener
On, 2 fastening hooks in Fig. 2 are fastened into 14 worm screw in Fig. 2 using 13 anchorage bars or rocking bar in Fig. 2, worm screw drives 11 whirlpool ruler in Fig. 2,
Whirlpool tape moves fastening hook, is fastened to union cloud cluster or flushes, other side fastening hook is also fastened, and drives V type clamp
It is pressed to figure union nut outer surface, presses 1 ratchet spanner in Fig. 2, ratchet spanner drives 15 gear shaft in Fig. 2, gear shaft
7 gears in band Fig. 2,5V type clamp in engaged gears Fig. 2 are rotated, V-type clamp drives union nut along the circumferential direction to move, into
The fastening of row union can not when V-type clamp is run to can not mutually be engaged with 7 gears in Fig. 2 or clamp connects with surrounding objects and touches
When continuing to move to, fastening hook is unclamped into 5mm or so using anchorage bar or rocking bar, moves 3 clamp handle in Fig. 2, by clamp remove to
Lower part again fastens fastening hook, presses ratchet spanner, reaches and fastens purpose repeatedly;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 union nut.
