background technique:
For modern industrial production, equipment and manufacture or inspection part are mutually fast, being tightly connected becomes more and more general, if sealing detection is as an important production technology, in many industries, be widely used, provide fast, being tightly connected reliably becomes a kind of urgent need.
Rapid pipe joint, as the important component part of equipment, not only affects Whole Equipment beat, also affects the stability of equipment.Because numerous parts is to consist of a plurality of individual cavity, and be with the port of equipment connection the straight tube that diameter differs, its inside and outside surface is black skin, and the conformity of size is poor.
Equipment with part connection procedure in, each straight tube of part and rapid pipe joint must seal, and have in the past external clamping joint or internal expansion type to clamp, because some part inside cavity pressurising is up to 5MPa, due to insufficient clamping force, in use often there is joint and rushed.
model utility content:
It is large that the purpose of this utility model is to provide a kind of clamping force, connects fast, and the cylindrical of good seal performance, endoporus clamp straight tube rapid pipe joint simultaneously.
The utility model is achieved in that
Cylindrical, endoporus clamps straight tube rapid pipe joint simultaneously, straight pin 19 in the eccentric opening in handle 15 off-axis left sides, one end coordinates with mandrel 10 is moving, mandrel 10 is fixedly connected with hollow screw 20, hollow screw 20 is communicated with the hole on axle sleeve 11 by the cavity of mandrel 10, axle sleeve 11 is connected with lining 9 is nested, axle sleeve 11 and lining 9 coordinate with mandrel is moving, the first nut 17 is threaded with axle sleeve 11, packing ring 18 is between handle 15 and the first nut 17, lining 9 coordinates with chuck 8 is moving, the inclined-plane that has cooperation at port, between lining 9 and chuck 8, there is the first spring 5, the gap that the outer wall of the inwall of chuck 8 and liner slide block 7 has straight pipe wall to pass through, liner slide block 7 inwalls have the inclined-plane of symmetrical inclined-plane expansion plug 16 outer walls symmetrical with two to coordinate, between two symmetrical expansion plugs, there is the second spring 6, expansion plug 16 is connected with the rectangular seal 13 on hollow screw 20 by the first copper packing 14, rectangular seal 13 is connected with the second nut 4 on screw rod by the second copper packing.
Between handle and the first nut, have spacer 18, the angle that this end of handle rotates with respect to spacer 18 is arc.
Axle sleeve 11 has O RunddichtringO with the nested face of lining 9, between axle sleeve 11 and lining 9 and mandrel, has O RunddichtringO.
The utility model clamping force is large, connects fast good seal performance.The utility model is inserted in the straight tube on part, move rapid pipe joint upper handle 1., by mandrel, straight tube is carried out to internal expanding, outer clip and sealing, guarantee the in the situation that of regulation pressure, stable, realization is reliably tightly connected.
accompanying drawing explanation:
Fig. 1 is the utility model structural drawing.
embodiment:
Straight pin 19 in the eccentric opening in handle 15 off-axis left sides, one end coordinates with mandrel 10 is moving, mandrel 10 is fixedly connected with hollow screw 20, hollow screw is communicated with the hole on axle sleeve 11 by the cavity of mandrel, axle sleeve 11 is connected with lining 9 is nested, axle sleeve 11 and lining 9 coordinate with mandrel 10 is moving, the first nut 17 is threaded with axle sleeve 11, packing ring 18 is between handle 15 and the first nut, lining coordinates with chuck 8 is moving, the inclined-plane that has cooperation at port, between lining and chuck, there is the first spring 5, the gap that the outer wall of the inwall of chuck and liner slide block 7 has straight pipe wall to pass through, liner slide block 7 inwalls have the inclined-plane of symmetrical inclined-plane expansion plug 16 outer walls symmetrical with two to coordinate, between two symmetrical expansion plugs, there is the second spring 6, expansion plug is connected with the rectangular seal 13 on hollow screw 20 by the first copper packing 14, rectangular seal 13 is connected with the second nut 4 on screw rod by the second copper packing.
Between handle and the first nut, have spacer 18, the angle that this end of handle rotates with respect to spacer 18 is arc.
Axle sleeve face nested with lining has O RunddichtringO, has O RunddichtringO between axle sleeve and lining and mandrel.
When handle 15 forwards Vertical direction shown in Fig. 1 to by level, because straight pin 19 is mounted on handle 15 in eccentric opening, under the acting in conjunction of handle 15, straight pin 19 and spacer 18, mandrel 10 is moved to the left, mandrel 10 is welded to connect with screw rod 20, and screw rod 20 is to be threaded with nut 4.Therefore, mandrel 10 is moved to the left simultaneously, by screw rod 20 and nut 4, power is delivered to copper packing 14, copper packing 14 is pressed rectangular seal 13 by copper packing 12, and rectangular seal is opened plug 16 by copper packing 12 compandings of left end, under the effect of expansion plug 16 ramps, the outer garden of liner slipping block 7 expanding, combine closely with inner hole of workpiece, by left end, expand plug 16 transmission of pressures simultaneously outer clip chuck 8 is moved to the left, under the effect on inclined-plane, realize overcoat to Workpiece clamping.
When handle 15 is rotated into horizontal position, spring 5 makes outer clip chuck 8 unclamp under the effect of spring force, and spring 6 makes liner slipping block 7 unclamp inner hole of workpiece under the effect of spring force.
O RunddichtringO 1,2 guarantees that entering gas can not leak.
The first nut 17 is to be threaded with axle sleeve 11, when the relative axle sleeve 11 of rotation the first nut 17 is moved to the left, by packing ring 18, handle 15, straight pin 19Dai moving mandrel 10, be moved to the left, mandrel 10 is moved to the left and drives chuck 8 to be moved to the left, under the acting in conjunction of lining 9 and chuck 8 ramps, dwindle chuck 8 and straight tube cylindrical contact diameter size, adapt to straight tube outside diameter and change in certain limit class.
Packing ring 18 is in order to increase the frictional contact surface of handle 15.
The effect of copper packing 14 is the support stiffness that improve copper packing 12.
Copper packing 12 effect is fixing rectangular seal 13, when rectangular seal 13 compressive deformation, guarantees that rectangular seal 13 cylindricals expand.
