Abstract
The invention discloses an anti-disengaging thread fastening device. The device comprises a fastener (1) and a first fixing piece (2). The fastener (1) comprises a fastener cap (11), a middle rod (12) and an end portion (13). The end portion (13) is provided with an outer thread. The diameter of the middle rod (12) is smaller than that of the end portion. A through hole (21) is formed in the middle of the first fixing piece (2) and internally provided with an inner thread matched with the outer thread. The anti-disengaging thread fastening device is simple in structure, convenient to install and capable of effectively preventing losing of the fastener.
Description
Technical field
The invention belongs to equipment technique for fixing field, in particular it relates to a kind of anticreep threaded fastening device.
Background technology
Existing screw threads for fastening mode many employings screw is directly connected to, and during dismounting, screw is easily lost, refitting
Time waste time and energy.
Summary of the invention
It is an object of the invention to, it is provided that a kind of anticreep threaded fastening device, this device is designed by rational structure,
After securing member is installed on fixture, securing member will not Automatic-falling, then by securing member by different fixing
Part fastens, and dismantles and installs the most very convenient again.
For reaching above-mentioned purpose, present invention employs following technical scheme:
A kind of anticreep threaded fastening device, described device includes securing member the 1, first fixture 2, described securing member 1
Including part cap 11, intermediate bar 12 and end 13, described end 13 arranges external screw thread, described intermediate bar 12 straight
Footpath is less than the diameter of end；In the middle of described first fixture 2, through hole 21 is set, sets and external screw thread in described through hole 21
The female thread matched.
Further, described device also includes that the second fixture 3, described second fixture 3 arrange installing hole 31,
Set, in described installing hole 31, the female thread matched with external screw thread.
Preferably, described through hole 21 is stepped hole.
Diameter due to intermediate bar 12 is less than the diameter of end, and the end external screw thread of heretofore described securing member 1 is screwed into
The through hole female thread of the first fixture 2, when external screw thread is fully threaded into, intermediate bar 12 is in through hole in free activity
State.
After the end of the securing member 1 of the present invention passes the first fixture 2, continue to be screwed into the installing hole 31 of the second fixture 3,
First fixture and the second fixture can be fixed together.
Present configuration is simple, easy for installation.
When the present invention dismantles, securing member and the second fixture are turned on, and such securing member cannot come off the first fixture,
Prevent securing member from losing.
Accompanying drawing explanation
Fig. 1 is the structural representation of apparatus of the present invention；
Reference: 1, securing member；11, part cap；12, intermediate bar；13, end；2, the first fixture；
21, through hole；3, the second fixture；31, installing hole.
Detailed description of the invention
With the drawings and specific embodiments, the present invention is further detailed explanation below.
As it is shown in figure 1, a kind of anticreep threaded fastening device, described device includes securing member the 1, first fixture 2 and
Second fixture 3, described securing member 1 includes that part cap 11, intermediate bar 12 and end 13, described end 13 are arranged
External screw thread, the diameter of described intermediate bar 12 is less than the diameter of end；In the middle of described first fixture 2, through hole 21 is set,
Setting the female thread matched with external screw thread in described through hole 21, described second fixture 3 arranges installing hole 31, described
The female thread matched with external screw thread is set in installing hole 31.
Described through hole 21 is stepped hole.
It should be noted last that, above example is only in order to illustrate technical scheme and unrestricted.Although
With reference to embodiment, the present invention is described in detail, it will be apparent to an ordinarily skilled person in the art that the present invention
Technical scheme modify or equivalent, without departure from the spirit and scope of technical solution of the present invention, it is equal
Should contain in the middle of scope of the presently claimed invention.
