Abstract
The utility model discloses a kind of simple dismounting-proof bolts, including threaded shank and nut portion；The threaded shank and the nut portion are integrally formed；The outer surface of the threaded shank is equipped with external screw thread, and nut portion top is equipped with the deep hole being recessed inwardly, and the inner wall of the deep hole is equipped with internal screw thread, and the external screw thread of the threaded shank and the internal screw thread of the deep hole match, and the nut portion is cylindrical structure.The utility model is not necessarily to specific purpose tool, it is only necessary to can tighten dismounting-proof bolt using another bolt, after dismounting-proof bolt is tightened, i.e., can not be removed again by tool, the dismounting-proof bolt is low in cost, and manufacturing process is simple, convenient and practical.
Description
Technical field
The utility model relates to bolt technical field, especially a kind of simple dismounting-proof bolt.
Background technique
Existing bolt does not have the function of tamper also, can both be fastened with tool, can also use same loosening tool, easily
It is removed.Especially existing dismounting-proof bolt, in use, it is also necessary to dedicated tool, specific purpose tool it is at high cost
It is high and not portable, using being inconvenient.
Number of patent application: 201610374644.6 disclose a kind of unidirectional dismounting-proof bolt, comprising: screw and nut, the spiral shell
The top screw thread of silk is equipped with a notch, and block tongue, flexible component in block tongue are equipped in notch；Screw is used cooperatively with nut,
There is nut card slot on nut.The card house structure of the patent not only needs dedicated tool to be fastened, together in use
When this application nut be traditional hexagonal structure, the bolt can be rotated out of easily using conventional tool, therefore, the bolt is simultaneously
Do not play the role of tamper really.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of simple dismounting-proof bolt, the application system
It makes simply, is easy to make, be not necessarily to specific purpose tool when in use, need to only use another plain bolt that can twist dismounting-proof bolt
Tightly, nut portion is cylindrical structure, prevents traditional hex nut from can screw out using tool.
The purpose of this utility model is achieved through the following technical solutions:
A kind of simple dismounting-proof bolt, including threaded shank and nut portion；
The threaded shank and the nut portion are integrally formed；
The outer surface of the threaded shank is equipped with external screw thread, and nut portion top is equipped with the deep hole being recessed inwardly, the depth
The inner wall in hole is equipped with internal screw thread, and the external screw thread of the threaded shank and the internal screw thread of the deep hole match.
Further, in the utility model preferred embodiment, the midpoint of the deep hole is located in the threaded shank
On axis.
Further, in the utility model preferred embodiment, the depth of the deep hole is less than the height in the nut portion
Degree.
Further, in the utility model preferred embodiment, the nut portion is cylindrical structure.
The beneficial effects of the utility model are:
(1) it is simple to manufacture, is easy to make, be not necessarily to specific purpose tool when in use, need to only use another plain bolt
Dismounting-proof bolt is tightened；
(2) nut portion is cylindrical structure, prevents traditional hex nut from can screw out using tool；
(3) cost of manufacture is cheap, and energy monomer member when in use, just cannot be unscrewed without assembly after tightening, can not
It removes, real anti-dismounting.
Detailed description of the invention

Fig. 2 is the perspective view of the utility model dismounting-proof bolt；
Fig. 3 is the sectional view of the utility model dismounting-proof bolt；
Fig. 4 is the top view of the utility model dismounting-proof bolt；
Fig. 5 is the scheme of installation of the utility model dismounting-proof bolt and workpiece；
In figure, 10- nut portion, 20- threaded shank, 30- deep hole, 40- plain bolt, 50- workpiece.
Specific embodiment
Illustrate the embodiments of the present invention below by way of specific specific example, those skilled in the art can be by this theory
Content disclosed by bright book understands other advantages and effect of the utility model easily.The utility model can also be by addition
Different specific embodiments are embodied or practiced, and the various details in this specification can also be based on different viewpoints and answer
With carrying out various modifications or alterations under the spirit without departing from the utility model.It should be noted that the case where not conflicting
Under, the feature in following embodiment and embodiment can be combined with each other.
It should be noted that diagram provided in following embodiment only illustrates the basic of the utility model in a schematic way
Conception, only shown in schema then with related component in the utility model rather than component count when according to actual implementation, shape
And size is drawn, when actual implementation kenel, quantity and the ratio of each component can arbitrarily change for one kind, and its assembly layout
Kenel may also be increasingly complex.
A kind of simple dismounting-proof bolt please refers to shown in attached drawing 1- attached drawing 4, including threaded shank 20 and nut portion 10；The spiral shell
Bar portion 20 and the nut portion 10 are integrally formed；The outer surface of the threaded shank 20 is equipped with external screw thread, 10 top of nut portion
Equipped with the deep hole 30 being recessed inwardly, the inner wall of the deep hole 30 is equipped with internal screw thread, the external screw thread of the threaded shank 20 with it is described
The internal screw thread of deep hole 30 matches, and the nut portion 10 is cylindrical structure.
Dismounting-proof bolt in the present embodiment please refers to shown in attached drawing 5, when in use, need to only be inserted with a plain bolt 40
The nut portion 10 for entering dismounting-proof bolt drives it to screw into required 50 position of workpiece, then reversely rotates plain bolt 40.This
When, since the contact surface of plain bolt 40 and dismounting-proof bolt is far smaller than the contact surface of dismounting-proof bolt Yu workpiece 50, dismounting-proof bolt
And the combination of workpiece 50 will closely much, so, invert plain bolt 40 at this time and not will drive dismounting-proof bolt and follow and exit, this
Sample is achieved that the tamper function of dismounting-proof bolt.
Further, in the above-described embodiments, the plain bolt 40 can also be replaced with another dismounting-proof bolt, whole
A process does not need specific purpose tool, when in use, just cannot unscrew after tightening, can not remove, real anti-dismounting.
It should be noted that in the present embodiment, the deep hole 30 in the nut portion 10 of dismounting-proof bolt only needs 3mm to 4mm i.e.
Can, less than the height in nut portion 10, the diameter of deep hole 30 is more bigger than the diameter in bolt portion 20, enables the external screw thread in bolt portion 20
Internal screw thread just with deep hole 30 matches.
Specific embodiment of the present utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.
