The model utility content
Wood model utility purpose is to provide a kind of structure of novel fractionation seam mating parts, easily part is caused damage to solve the existing fractionation mode of knocking, and affects the technical problem of usability.
For achieving the above object, the utility model provides a kind of structure that splits the seam mating parts, comprises first component, the second component coordinated with the first component seam, jackscrew nut and jackscrew screw; Wherein, the jackscrew nut is installed in second component, and the jackscrew screw enters in the jackscrew nut in second component one sidespin, and pushes first component extremely away from second component.
Further, the end face of second component is provided with the shoulder hole of perforation vertically, and the large aperture of shoulder hole is near the end face joint place of first component and second component; The jackscrew nut is T-shaped tube-in-tube structure, and the large footpath periphery of jackscrew nut is arranged in the macropore of shoulder hole, and the backward end face away from first component of the path periphery of jackscrew nut and the aperture interference fit of shoulder hole extends.
Further, the overhanging end of jackscrew nut is provided with and is beneficial to the breach that clamping is installed, and breach is symmetrical arranged.
Further, the end face of first component is provided with the jackscrew groove, and the jackscrew groove is over against the endoporus of jackscrew nut.
Further, the jackscrew groove is circle or U-shaped.
Further, the jackscrew nut is along circumferentially evenly being arranged at the end face of second component.
The utlity model has following beneficial effect: its jackscrew nut is installed in second component, the jackscrew screw is with after the jackscrew nut thread coordinates, push first component and make it the end face away from second component, thereby make the seam cooperating structure of first component and second component be split.This is simple in structure, easy to operate and not fragile component.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.Below with reference to figure, the utility model is described in further detail.
The accompanying drawing explanation
The accompanying drawing that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural profile schematic diagram of the fractionation seam mating parts of the utility model preferred embodiment;
Fig. 2 is the second component of the utility model preferred embodiment and the assembling schematic diagram of jackscrew nut;
Fig. 3 is the schematic top plan view of structure of the fractionation seam mating parts of the utility model preferred embodiment; And
Fig. 4 is the structural representation of jackscrew groove of the first component of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1, the utility model provides a kind of structure that splits the seam mating parts, and it comprises first component 1, the second component 2, jackscrew nut 3 and the jackscrew screw 4 that with first component 1 seam, coordinate.Wherein, first component 1 is provided with the inner stopper structure, and second component 2 is provided with the outer stopper structure, and first component 1 and second component 2 are tight by the laminating of the end face of two parts after by inside and outside fixing structure, coordinating; Jackscrew nut 3 is installed in second component 2, and jackscrew screw 4 enters in jackscrew nut 3 in second component 2 one sidespins, and pushes first component 1 to away from second component 2.This is simple in structure, easy to operate and not fragile component.
Preferably, jackscrew nut 3, along circumferentially evenly being arranged at the end face of second component 2, can evenly arrange a plurality of according to the size of accessory size.
Referring to Fig. 2, the end face of second component 2 is provided with the shoulder hole 22 of perforation vertically, and the large aperture of shoulder hole 22 is near the end face joint place of first component 1 and second component 2; Jackscrew nut 3 is T-shaped tube-in-tube structure, and the large footpath periphery of jackscrew nut 3 is arranged in the macropore of shoulder hole 22, and the backward end face away from first component 1 of the path periphery of jackscrew nut 3 and the aperture interference fit of shoulder hole 22 extends.
In conjunction with Fig. 3, the overhanging end of jackscrew nut 3 is provided with and is beneficial to the breach 30 that clamping is installed, and breach 30 is symmetrical arranged.
Referring to Fig. 4, the end face of first component 1 is provided with jackscrew groove 12, and jackscrew groove 12 is over against the endoporus of jackscrew nut 3, and jackscrew screw 4 turn-knobs fall in jackscrew groove 12 to first component 1, avoid the end face of first component 1 to be scratched.Jackscrew groove 12 is circle or U-shaped, is convenient to processing.
During use, the instruments such as employing spanner split circumferential uniform a plurality of fastening pieces, end face along first component screws in jackscrew screw 4 in jackscrew nut 3 again, jackscrew screw 4 pushes to the jackscrew grain 12 of first component 1 and continues to screw jackscrew screw 4 again, and the seam cooperating structure of first component 1 and second component 2 is split.
