Description
Technical field
The utility model is related to mechanical equipment technical field, specially a kind of nut stretcher.
Background technology
Because in machinery production, nut is the essential fastener of mechanical package, thus the tensile strength of nut into
One device whether the important symbol of safety and stability, the tensile strength to nut is detected when more use nut
Stretcher carries out detecting its intensity, but existing detection device is single nut detection device, does not possess many nuts simultaneously
The demand of tensile strength is detected, the detections of many nut tensile strengths is detected to reach so being badly in need of designing relevant device.
Utility model content
The purpose of this utility model is to provide a kind of nut stretcher, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of nut stretcher, including the first drawing
Boom, the first bearing pin, sleeve and the second stretch rod, one end of first stretch rod are provided with the second connecting plate, described first
The stretch rod of bearing pin insertion first and the second connecting plate are simultaneously fixedly connected with the first clamp nut in upper end, under first bearing pin
End is fixedly connected with the 4th clamp nut, and the sleeve is fixedly connected with the second connecting plate by the first bolt and the second bolt,
One end of second stretch rod is fixedly connected with the first connecting plate, and the side of first connecting plate is provided with screw rod, described
Screw rod is fixedly connected with the inside of bottom plate, the nut by nut and is provided with backing plate, and the side of the sleeve is plugged with second
Bearing pin, the threaded upper ends of second bearing pin are connected with the second clamp nut, and the lower end of second bearing pin is threaded with
Three clamp nuts.
It is preferred that, multigroup nut structure is provided with the bottom plate.
It is preferred that, the bottom plate is square tubular structure.
It is preferred that, the internal diameter of the sleeve is identical with the external diameter of bottom plate.
Compared with prior art, the beneficial effects of the utility model are：The nut stretcher is rational in infrastructure, creates many spiral shells
Female detection device, traditional single nut detection device is replaced, higher operating efficiency is made it have, while by removable
Handler makes it more facilitate during nut is installed, and greatly improves degree easy to use.
Brief description of the drawings
Fig. 1 is the utility model side sectional view.
Fig. 2 is the utility model bottom plate top view.
In figure：It is 1 first stretch rod, 2 first bearing pins, 3 first clamp nuts, 4 first bolts, 5 second bearing pins, 6 second tight
Gu nut, 7 bottom plates, 8 first connecting plates, 9 second stretch rods, 10 backing plates, 11 nuts, 12 screw rods, 13 the 3rd clamp nuts, 14 sets
Cylinder, 15 second bolts, 16 the 4th clamp nuts, 17 second connecting plates.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of nut stretcher, including the first stretching
Bar 1, the first bearing pin 2, the stretch rod 9 of sleeve 14 and second, the internal diameter of the sleeve 14 are identical with the external diameter of bottom plate 7, match somebody with somebody with bottom plate 7
To connection, one end of first stretch rod 1 is provided with the second connecting plate 17, the He of 2 the first stretch rod of insertion of the first bearing pin 1
Second connecting plate 17 is simultaneously fixedly connected with the first clamp nut 3 in upper end, and the lower end of first bearing pin 2 is fixedly connected with the 4th
Clamp nut 16, the sleeve 14 is fixedly connected with the second connecting plate 17, described second by the first bolt 4 and the second bolt 15
One end of stretch rod 9 is fixedly connected with the first connecting plate 8, and the side of first connecting plate 8 is provided with screw rod 12, the screw rod
12 are fixedly connected with bottom plate 7 by nut 11, and the bottom plate 7 is square tubular structure, is connected with the pairing of sleeve 14, the bottom
Multigroup structure of nut 11 is provided with plate 7, the tensile strength of multigroup nut can be detected simultaneously, while also selection carries out list
Nut is detected, is greatly improved it and is flexibly used characteristic, the inner side of the nut 11 is provided with backing plate 10, the one of the sleeve 14
Side is plugged with the second bearing pin 5, and the threaded upper ends of second bearing pin 5 are connected with the second clamp nut 6, second bearing pin 5
Lower end is threaded with the 3rd clamp nut 13.
Operation principle：Bottom plate 7 can be separated with sleeve 14, it is more facilitated in fixing nut 11, when deployed, will
Nut 11 is threaded on screw rod 12, if necessary to be detected to single nut 11, also can only connect one or more, significantly
Add its usability, make its more convenience and high-efficiency, be fixedly connected after nut 11, it is only necessary to just can be quick by the second bearing pin 5
