Abstract
The utility model discloses a tool for preventing screw rotation in a process of fastening a double-thread screw. The tool comprises an L-shaped handle, and a fixing nut, wherein the L-shaped handle is fixedly connected with the fixing nut which is a hexagon nut identical to the double-thread screw to be fastened in thread specification; and the thickness of the fixing nut is equal to the length of the end part of the double-thread screw required to extend out of the nut. The tool provided by the utility model can well solve the problems that screw rotation is hard to prevent and extending length of the screw is hard to control in the process of fastening the double-thread screw in product assembly; the tool can prevent rotation of the screw and simultaneously can control the extending length of the double-thread screw to meet the specified requirement in the process of fastening the double-thread screw. In addition, the tool is light, convenient, simple and practical, and can improve the work efficiency while improving the product quality.
Description
Technical field
The utility model relates to a kind of power tool of securing member, relates to specifically a kind of double threaded screw and prevent bolt rotary and the servicing unit that the screw rod extension elongation is controlled in the fastening nuts process, belongs to fastening and the extracting tool field.
Background technology
In various products and device assembles process, usually use the stud conduct with one of interconnective method of a plurality of connected components, in the fastening process of double threaded screw, an end nut is carried out occurring easily when fastening the situation of bolt rotary, so that the time-consuming again effort of fastening process; Simultaneously the product of part and the equipment spiro rod length that stretches out nut after to fastening finishing has proposed requirement, shown in the size L as shown in fig. 1.At present, not having a kind of instrument can prevent from when screw rod from rotating the spiro rod length that stretches out nut being controlled when fastening double threaded screw.Therefore, be necessary to design and develop a kind of new tool and solve above-mentioned technical problem.
The utility model content
The purpose of this utility model is can prevent bolt rotary, the instrument that prevents the fastening process bolt rotary of double threaded screw of simultaneously the double threaded screw tip lengths of stretching out nut being controlled for above-mentioned technical problem proposition is a kind of when double threaded screw is fastening.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of instrument that prevents the fastening process bolt rotary of double threaded screw comprises " L " shape handle, hold-down nut; Described " L " shape handle and hold-down nut are fixed together; Described hold-down nut is hex nut, and the screw thread specification of described hex nut is identical with the screw thread specification of fastened double threaded screw.
Further, the thickness of described hold-down nut is identical with the double threaded screw tip lengths that requires to stretch out nut.
Further, described " L " shape handle and hold-down nut are by being welded together.
When well solving the fastening double threaded screw of Product Assembly process, the utility model is difficult for the screw rod anti-rotation that realizes and the problem that the screw rod extension elongation is controlled, the length that the control double threaded screw stretches out when the fastening process of double threaded screw prevents bolt rotary, make extension elongation requirement up to specification, and light and handy convenient, simple and practical, in Improving The Quality of Products, also improved operating efficiency.
Description of drawings
Fig. 1 is the scheme of installation of studs;
Fig. 2 is the structural representation that prevents the instrument of the fastening process bolt rotary of double threaded screw;
Fig. 3 is the structural scheme of mechanism of embodiment two;
Fig. 4 is the structural representation of embodiment three.
Among the figure: 1. " L " shape handle, 2. hold-down nut, 3. studs, 4. steel pipe.
The specific embodiment
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for the art those of ordinary skill, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
As shown in Figure 2, a kind of instrument that prevents the fastening process bolt rotary of double threaded screw comprises " L " shape handle 1, hold-down nut 2; " L " shape handle 1 is fixedly connected by welding with hold-down nut 2 and is in the same place; Hold-down nut 2 is hex nut, and the screw thread specification of hex nut is identical with the screw thread specification that needs fastening double threaded screw 3; The thickness of hold-down nut 2 is identical with double threaded screw 3 tip lengths that nut is stretched out in requirement.
As shown in Figure 3, embodiment two, with the difference of embodiment one be: the thickness of selected hold-down nut 2 is greater than double threaded screw 3 tip lengths that require to stretch out nut, hold-down nut 2 processed remove part height, the thickness that makes hold-down nut 2 is identical with double threaded screw 3 tip lengths that require to stretch out nut.Further, described " L " shape handle and hold-down nut also can be to tighten together by inside and outside boss structure tight fit by being welded together.
As shown in Figure 4, embodiment three, and with the difference of embodiment one be: the thickness of hold-down nut 2 is L1, require to stretch out double threaded screw 3 tip lengths L2, the wherein L2＞L1 of nut; Weld one section round steel pipe 4 the another side centering of hold-down nut 2, the length of round steel pipe 4 is L2-L1, and the internal diameter of round steel pipe 4 is slightly larger than the Major Diam of double threaded screw 3.
The utility model using method: adjust the extension elongation of double threaded screw 3 one ends greater than double threaded screw 3 tip lengths that require to stretch out nut, rotary handle 1 is threaded into the end that handle 1 withstands double threaded screw 3 with hold-down nut 2, outwards turn clamp nut and withstand hold-down nut 2, tighten the clamp nut of double threaded screw 3 other ends, namely finished the fastening of double threaded screw 3.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
