Abstract
This utility model provides a kind of screw, including: screw rod, described screw rod is provided with screw thread；Nut, described nut is connected with one end of described screw rod；Anti-riveting portion, described anti-riveting portion is connected with the other end of described screw rod.This utility model, by improving the structure of screw, increases anti-riveting portion on screw, makes screw be mounted so as to more firm, durable in use；It addition, by the position and the length that adjust screw thread, it is to avoid screw thread produces stripped thread phenomenon, further enhances the fastness that screw is installed.
Description
Technical field
This utility model relates to a kind of screw.
Background technology
In repair procedures, the handle spoilage of each adnexa in integrated navigation apparatus system is higher, through analyzing, is due to the too short stripped thread phenomenon caused of screw thread when design of the screw in handle, thus causes handle cannot normally lock and unclamp.
Utility model content
The purpose of this utility model is to provide a kind of screw, it is possible to make screw be mounted so as to more firm.
For solving the problems referred to above, this utility model provides a kind of screw, including:
Screw rod, described screw rod is provided with screw thread；
Nut, described nut is connected with one end of described screw rod；
Anti-riveting portion, described anti-riveting portion is connected with the other end of described screw rod.
Further, in above-mentioned screw, described anti-riveting portion is cylindrical.
Further, in above-mentioned screw, described anti-riveting portion is the cylindrical of hollow.
Further, in above-mentioned screw, described screw rod is divided into the part near nut and the part near anti-riveting portion, wherein, is only being threaded in the part of described nut.
Further, in above-mentioned screw, the length of the screw thread arranged in the part of described nut accounts for 2nd/1 to three/2nds of whole spiro rod length.
Further, in above-mentioned screw, described nut is provided with spiral shell cutter groove.
Further, in above-mentioned screw, described spiral shell cutter groove is in-line.
Compared with prior art, this utility model, by improving the structure of screw, increases anti-riveting portion on screw, makes screw be mounted so as to more firm, durable in use；It addition, by the position and the length that adjust screw thread, it is to avoid screw thread produces stripped thread phenomenon, further enhances the fastness that screw is installed.
Accompanying drawing explanation
Fig. 1 is the structure chart of the screw of this utility model one embodiment.
Detailed description of the invention
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, with detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, this utility model provides a kind of screw, including:
Screw rod 1, described screw rod 1 is provided with screw thread 4；
Nut 2, described nut 2 is connected with one end of described screw rod 1；
Anti-riveting portion 3, described anti-riveting portion 3 is connected with the other end of described screw rod 1.Concrete, after described screw is screwed in fixed position, by tapping anti-riveting portion, make the deformation of anti-riveting portion generate the plane of flattening turned up, with fixed position riveted so that screw is mounted so as to more firm, durable in use.
Preferably, described anti-riveting portion 3 is cylindrical.
Preferably, described anti-riveting portion 3 is the cylindrical of hollow, thus tap time, anti-riveting portion be easier to deformation turn up generation extend.
Preferably, described screw rod 1 is divided into the part near nut 2 and the part near anti-riveting portion 3, wherein, only in the part of described nut 1, it is being threaded 4, thus avoid screw thread to produce stripped thread phenomenon, further enhance the fastness that screw is installed, and in the part in the close anti-riveting portion that need not screw thread, it is not provided with screw thread, thus reduces production cost.
Preferably, the length of the screw thread 4 arranged in the part of described nut 2 accounts for 2nd/1 to three/2nds of whole spiro rod length.
Preferably, described nut 2 is provided with spiral shell cutter groove 5.
Preferably, described spiral shell cutter groove 5 is in-line.
In sum, this utility model, by improving the structure of screw, increases anti-riveting portion on screw, makes screw be mounted so as to more firm, durable in use；It addition, by the position and the length that adjust screw thread, it is to avoid screw thread produces stripped thread phenomenon, further enhances the fastness that screw is installed.
In this specification, each embodiment uses the mode gone forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, and between each embodiment, identical similar portion sees mutually.
Obviously, those skilled in the art can carry out various change and modification without deviating from spirit and scope of the present utility model to utility model.So, if these amendments of the present utility model and modification belong within the scope of this utility model claim and equivalent technologies thereof, then this utility model is also intended to change and including modification include these.
