Situation about losing, has certain potential safety hazard.
Content of the invention
For solving above-mentioned technical problem, the utility model provides a kind of Anti-theft belt flange nut.
The technical solution adopted in the utility model is：Anti-theft belt flange nut, including nut body, flange platform and antitheft envelope
Closed end lid, nut body is the cylindric of hollow, is provided with screw thread, flange platform and theft-proof closed end cap position respectively inside nut body
In the two ends of nut body, theft-proof closed end cap is in the form of a column, and one end of nut body is closed by theft-proof closed end cap.
Preferably, theft-proof closed end cap section is triangle or side number is the polygon of odd number.
Preferably, flange platform interior diameter is identical with nut body interior diameter, and flange platform overall diameter is more than straight outside nut body
Footpath.
Preferably, theft-proof closed end cap circumscribed circle diameter is equal to or less than nut body overall diameter.
Preferably, flange tread has tooth side to be embossed, and the embossing of tooth side is uniformly distributed in flange platform annular table in fan-shaped stupefied shape
Face.
The utility model has the advantages and positive effects that：Nut body is round and smooth, nut afterbody theft-proof closed end cap shape
Shape is special, does not have parallel surface or diagonal, commonly opens button or monkey wrench can not be dismantled to it, have anti-theft feature；That closes is interior
The screw rod of fully wrapped around nut socket is capable of in chamber, and screw rod tail end will not expose, and has antirust function；Mosaic mode installs spiral shell
When female, nut can be hidden in pothole to be installed, is mounted and dismounted by special supporting extracting tool, convenient operation and
Antitheft.
Brief description

In figure：
1st, theft-proof closed end cap 2, nut body 3, flange platform
4th, screw thread
Specific embodiment
Below in conjunction with the accompanying drawings an embodiment of the present utility model is explained.
As shown in Fig. 1 Fig. 2, the utility model Anti-theft belt flange nut, including nut body 2, flange platform 3 and theft-proof closed
End cap 1, nut body 2 is the cylindric of hollow, and surface is round and smooth, is provided with screw thread 4, flange platform 3 and antitheft envelope inside nut body 2
Closed end lid 1 is located at the two ends of nut body 2 respectively, and one end of nut body 2 is closed by theft-proof closed end cap 1, forms inner chamber, protects
Protect screw rod therein not by corrosion, theft-proof closed end cap 1 is in the form of a column, theft-proof closed end cap 1 section is triangle or side number is strange
The polygon of number, such structure makes end cover structure not have parallel surface or diagonal, commonly opens button or monkey wrench can not be to it
Dismounting, only special coupling extracting tool could carry out to it installing or removing work, has anti-theft feature；Nut body 2
The flange platform 3 of opposite side can increase the contact area of nut and vehicle frame, makes locking intensity more firm, flange platform 3 ground has
Tooth side is embossed, and the embossing of tooth side is uniformly distributed in flange platform 3 annular surface, the tooth side embossing tool on flange platform 3 surface in fan-shaped stupefied shape
Have necessarily anti-skidding effect, be conducive to the fastening effect of nut, after anti-nut Long-Time Service produce loosen, flange platform 3 interior diameter with
Nut body 2 interior diameter is identical, and flange platform 3 overall diameter is more than nut body overall diameter, theft-proof closed end cap 1 circumscribed circle diameter etc.
In or be less than nut body 2 overall diameter, when nut is used for inlaying installation, inlays position size and need to be more than flange platform 3 diameter, from
Under tapered upwards structure convenient cooperation coupling extracting tool, so that nut also can conveniently can be pacified in less working space
Assembly and disassembly are unloaded, and the nut inlaying installation can not destroy the attractive in appearance of fixing device, it may have the anti-function of scratching.
