Abstract
The utility model relates to a combined detachable jack screw, which comprises at least one adjusting screw stem. Supporting nuts are arranged at two ends of each adjusting screw stem, and the adjusting screw stems and the supporting nuts are connected in series and screwed to form a sectional jack structure including at least three sections. The combined detachable jack screw avoids damages of sealing parts, guaranteeing assembling quality, and meets requirements of assembling various pipeline valves.
Description
Technical field
The utility model relates to a kind of screw-jack, relates in particular to be used for a kind of knockdown detachable screw-jack that the pipeline valve body is installed.
Background technology
In the punching production workshop, the press noodle preparation machine is covered with various pipelines in the hole, rely on valve body to be connected between pipeline and the pipeline, because the press tonnage is huge, various pipeline valve body individualities are huge, and indivedual monolithic valve body are near 100 kilograms, when assembling various pipeline valve body once more, because the elastic deformation of pipeline self, usually behind the pipeline valve body of dismantling, the pitch smaller between two pipelines is when assembling valve body once more, very waste time and energy, and the valve body two ends are added with sealing member, and are very easily damaged in fitting process repeatedly, use in the near future, the valve body seepage will occur, influence assembly quality.
Summary of the invention
The utility model has solved the existing in prior technology problem that the pipeline spacing is dwindled when the various valve body of assembling, a kind of knockdown detachable screw-jack is provided, avoid the sealing member breakage, guaranteed the quality of assembling, satisfied the demand of assembling various pipeline valve bodies.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: it comprises at least one adjusting screw(rod), described adjusting screw(rod) two ends are provided with support thing nut, and described adjusting screw(rod) is connected in series the segmentation jack structure that screws at least three sections with support thing nut.Can select the screw rod and the nut of different size during use according to actual conditions for use, by cooperating of screw rod and nut, swivel nut is adjusted the actual length of screw-jack, thereby the spacing between two pipelines is backed down, reduce two elastic deformation amounts between the pipeline, increase distance between the two, thereby realize valve body light in working order packing into.
As preferably, described adjusting screw(rod) cross section is cylinder, and periphery is provided with screw thread, has the keyway that is used for fixing spanner at the cylinder middle part.Keyway is used for fixing coes wrench, cooperates with nut by screw thread, makes it to reach the effect of regulating length.
As preferably, described support thing nut is the regular hexagon cylinder, and the centre is provided with screw hole, is shaped on the screw thread that matches with screw rod in the described screw hole.Support thing nut has the length plurality of specifications, and in use, support thing nut can screw in the adjusting screw(rod).
As preferably, the material of described adjusting screw(rod) and support thing nut is the steel that surface hardening was handled.
The beneficial effect that the utility model brings is, and is simple in structure, mainly is made up of screw rod, nut, is easy to make; Use simple to operately, only need screw rod and joint nut to be combined together and get final product; According to the actual requirements, use the screw rod and the nut of different size, time saving and energy saving.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: a kind of knockdown detachable screw-jack such as Fig. 1,2,5 of present embodiment, integral body is made for steel material, comprise an adjusting screw(rod) 2 and two support thing nuts 1, adjusting screw(rod) 2 cross sections are cylinder, periphery is provided with screw thread, has the keyway 3 that is used for fixing spanner at the cylinder middle part, and support thing nut 1 is the regular hexagon cylinder, the centre is provided with the adjusting screw(rod) hole, is shaped on the screw thread that matches with adjusting screw(rod) 2 in the adjusting screw(rod) hole.The support thing nut 1 at adjusting screw(rod) 2 and two ends matches and screws, and realizes the adjusting of length by the screw thread fit that rotation is adjusted between the two, thereby reaches application target.
Embodiment 2: shown in Fig. 3,4,6, the detachable knockdown adjusting screw(rod) jack of present embodiment comprises two adjusting screw(rod)s 2 and three support thing nuts 1, adjusting screw(rod) 2 and support thing nut 1 be the serial connection section of fitting in successively, wherein Zhong Bu support thing nut 1 is selected long support thing nut 1 for use, and short support thing nut 1 is selected at two for use.
During use, according to the actual requirements, select the adjusting screw(rod) 2 and support thing nut 1 of different size, two support thing nuts 1 are got final product by screw thread fit with adjusting screw(rod) 2 respectively.Realize the adjusting of length by the screw thread fit that rotation is adjusted between the two, thereby reach application target.
