Abstract
The utility model relates to an anti-theft clamp device comprising a clamp body and fixing screws, wherein the clamp body is divided into an upper part and the lower part. The anti-theft clamp device is characterized in that the clamp body is in a thickened structure, both ends of the upper half part are thickened and drilled into step holes, both ends of the lower half part are provided with inner threads, and the fixing screws are engaged with the inner threads, are in an inner pentagonal countersunk type structure and are all sunk in the clamp body. The anti-theft clamp device is provided with the inner pentagonal screws formed by carrying out cemented quenching to No.45 steel, the surface hardness can reach about HRC60, and the anti-sawing capacity of the screws is improved; and the anti-theft clamp device has the characteristics of simple structure, convenient manufacturing, theft and tamper prevention, sawing and destroy prevention and the like and is mainly applied to the valve and pipeline connection of oil extraction well mouths and similar occasions.
Description
One, technical field:
The utility model is a kind of anti-theft device, specifically is a kind of antitheft device of five side's screws in the countersunk head that utilizes.
Two, background technique:
Traditional clip is conventional mode of structure, is tightened up and down by screw bolt and nut, for contribution has been made in the connection of valve and pipeline, but it exists following shortcoming or deficiency simultaneously: 1, do not have anti-theft measure effectively, often lose dress, adorned and lost, make troubles to production; Though steal 2 employing electric welding are firmly still often cut by stealer stud weld with hacksaw after, influenced normally carrying out of crude oil production, cause tremendous loss for country and enterprise.
Three, summary of the invention:
The purpose of this utility model is exactly the problem that exists at prior art, designs a kind of simple in structurely, is convenient to make clip device that can be effectively antitheft.
A kind of Theft-proof collar clamp device described in the utility model, comprise clip body and set screw, clip is divided into two-part up and down, it is characterized in that described clip body is the thickening type structure, the thickening of upper half part two ends also is drilled to step hole, and lower half portion two ends are provided with internal thread, and set screw is meshed with this internal thread, set screw is interior five side's countersunk structures, and set screw all sinks in the clip body.
Wherein, described clip body is the member that No. 45 steel carburizing and quenchings are made, and its hardness is HRC56～60.Described set screw is interior five side's countersunk screw member that No. 45 steel carburizing and quenchings are made, and its hardness is HRC56～60.
The utility model has the advantages that: simple in structure, be convenient to make, effectively prevent to steal to unload and destroy with sawing, improve the anti-theft capability of clip greatly.Can prevent to steal and tear open, can prevent that again sawing from destroying.
Four, description of drawings:
Accompanying drawing is a kind of structural representation of the present utility model:
Five, embodiment:
With reference to accompanying drawing, a kind of Theft-proof collar clamp device comprises clip body 1 and set screw 2, and clip is divided into two-part up and down.Clip body 1 is the thickening type structure, and the thickening of upper half part two ends also is drilled to step hole, and lower half portion two ends are provided with internal thread, and set screw 2 is meshed with this internal thread, and set screw 2 is interior five side's countersunk structures, and set screw 2 all sinks in the clip body.
