Description

A kind of yoke configurations

Technical field

The present invention relates to a kind of instrument, more particularly to a kind of yoke configurations.

Background technology

, it is necessary to be connected both by pipe sleeve two pipe junctions, the thick pipe in part can for electric wire sleeve pipe, downcomer etc. Adapter is realized in a manner of using thermoplastic softening, part material is relatively thin, or said material is not suitable for the adapter of thermoplastic, it is necessary to pass through After gluing, the mode got into takes over, and is limited by construction environment and construction site, and manpower difficulty of construction is larger, and holds Adapter breakage or deformation are easily caused, butt tube effect, aesthetics, watertightness and security have harmful effect.

Particularly in downcomer adapter operation process, adapter includes two and treats that adapter and an adapter cover, adapter set Both ends are respectively provided with stress step, because upper end water pipe and lower end water pipe are in stationary state, and are typically at corner, by ring The limitation in border, it can not be taken over by the way of the propulsion of other pressure.

Clip is particularly important for casing bit, and it needs, and installation is simple, is connected firmly.

The content of the invention

The purpose of the present invention is to be directed to above mentioned problem existing for existing technology, there is provided a kind of yoke configurations, institute of the present invention Technical problems to be solved are how to improve the precision and stationarity of sleeve pipe.

The purpose of the present invention can be realized by following technical proposal：A kind of yoke configurations, it is characterised in that including two Semicircular body, there is the chute of rectangular in cross-section in the body, slidably connect a slide bar in the chute, described The escape groove of connection chute is offered on the lateral wall of body, the push rod being plugged in escape groove is fixedly installed on the slide bar, Several catch are hinged with the slide bar, a stage clip is connected between the catch and slide bar, is set on the inwall of the chute It is equipped with the pawl for making catch unidirectionally be swung around pin joint.

Slide bar can unidirectionally slide in chute, can make any slide bar by pulling push rod while be plugged in same cunning In groove, it is fixed together so as to measure two bodies, can continues unidirectionally to slide slide bar, an intrinsic slide bar moves to another In chute in individual slide bar, another slide bar similarly, just can realize separation to two body joining places, two bodies, this Be not in release in operation process when two bodies are fixed together since sample.

In a kind of above-mentioned precisely casing bit, the body includes interlude made of metal material and two sections are located at The stretch section of interlude both sides, the stretch section are made up of plastic material.

Interlude on body can be used for the fixation with miscellaneous part, provided by elastic tip and wrap up pressure to be taken over Clamp force.

In a kind of above-mentioned precisely casing bit, there is skid resistant course made of quality of rubber materials on the inwall of the body.

In a kind of above-mentioned precisely casing bit, the chute inwall limits catch outer end, makes the hard-over of catch Less than 30 °.

In a kind of above-mentioned precisely casing bit, the non-return direction of the catch limitation slide bar is identical.

In a kind of above-mentioned precisely casing bit, the pawl is arranged on two vertical walls of chute inwall, institute The both ends for stating slide bar have two catch respectively, are connected between two catch of the slide bar with end by same root stage clip, institute The through hole for being offered on slide bar and allowing stage clip to pass through is stated, stage clip is in compressive state.

Two catch of same stage clip connection can have more preferable stability and synchronism, so as to prevent one-way non-return from losing Effect.

Embodiment

It is the specific embodiment of the present invention and with reference to accompanying drawing below, technical scheme is further described, But the present invention is not limited to these embodiments.

As depicted in figs. 1 and 2, including two semicircular bodies 11, there is the chute 12 of rectangular in cross-section in body 11, A slide bar 13 is slidably connected in chute 12, the escape groove 14 of connection chute 12, slide bar 13 are offered on the lateral wall of body 11 On be fixedly installed the push rod 15 being plugged in escape groove 14, several catch 16, catch 16 and slide bar are hinged with slide bar 13 A stage clip 17 is connected between 13, the pawl for making catch 16 unidirectionally be swung around pin joint is provided with the inwall of chute 12.

Slide bar 13 can unidirectionally slide in chute 12, can make any slide bar 13 by pulling push rod 15 while plug In same chute 12, it is fixed together so as to measure two bodies 11, can continues unidirectionally to slide slide bar 13, in a body 11 Slide bar 13 move in the chute 12 in another slide bar 13, another slide bar 13 similarly, is just connected to two bodies 11 Place, two bodies 11 can realize separation, so since, when two bodies 11 are fixed together, be not in operation process Release.

Body 11 includes interlude 21 made of metal material and two sections of stretch sections 22 for being located at the both sides of interlude 21, elasticity Section 22 is made up of plastic material；Interlude 21 on body 11 can be used to fix with other accessories, provided by elastic tip Wrap up a to be taken over thrust.

There is skid resistant course 23 made of quality of rubber materials on the inwall of body 11；The inwall of chute 12 limitation catch 16 outer end, makes The hard-over of catch 16 is less than 30 °.

The non-return direction that catch 16 limits slide bar 13 is identical；Pawl is arranged on two vertical walls of the inwall of chute 12, The both ends of slide bar 13 have two catch 16 respectively, pass through same root stage clip 17 between two catch 16 of the slide bar 13 with end It is connected, the through hole for allowing stage clip 17 to pass through is offered on slide bar 13, stage clip 17 is in compressive state.

Two catch 16 that same stage clip 17 connects can have more preferable stability and synchronism, so as to prevent unidirectional stop Return failure.

Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
