Abstract

The utility model provides an anti-theft connection device, which comprises a connecting piece, and is characterized in that the end of the connecting piece is clamped with a jacket internally provided with a cavity, and provided with an opened inner end and a blocked outer end. The jacket is clamped on the connecting piece through a spring ring conveniently, so that the jack is only rotated along the periphery of the connecting piece, and cannot axially move, looseness and movement of the connecting piece can be effectively prevented, so that easily-stolen components or parts cannot be stolen, the long-distance frequent reciprocating movement cannot be influenced, a special tool is not provided, and security of multiple detachable structures can be protected.

Description

A kind of antitheft connection set

Technical field

The utility model relates to a kind of anti-theft device, especially a kind ofly is used to prevent that outdoor being prone to from stealing the stolen connection set of parts, belongs to antitheft Component Design and manufacturing technology field.

Background technique

At present, be installed in outdoor easy robber's parts and part connects through anti-theft bolt mostly and fixing, with prevent to be prone to steal parts and part stolen.Known anti-theft bolt has multiple; Wherein a kind of is the helical thread portion fluting at bolt, treat that bolt and nut is fastened to design load after, the metal bar of respective shapes is inserted in the fluting of bolt; To destroy the worm structure of bolt and nut; Increase the dismounting difficulty of bolt, prevent to be prone to steal parts and part stolen, it is inapplicable that this anti-theft bolt comes and goes being threaded of moving to long distance and frequent; Another kind of anti-theft bolt then is that bolt, nut and the supporting special tool by given shape constitutes, and bolt, nut fastening and looseningly have only supporting special tool could accomplish uses the instrument of routine to accomplish; Can reach the purpose of antitheft like this; But this anti-theft bolt is owing to will be equipped with special tool, and not only cost is high, and uses inconvenience; Especially after special tool is obtained by the lawless person, also just lost the effect of antitheft.Therefore, be necessary existing technology is improved.

Summary of the invention

Can not grow frequent round the moving of distance for overcoming existing anti-theft bolt, perhaps increase cost because of being equipped with special tool, and bring problems such as using inconvenience, the utility model provides a kind of antitheft connection set.

The utility model solves the technological scheme that its technical problem adopted: a kind of antitheft connection set; Comprise link; It is characterized in that interior band cavity of link end and its and sheath clamping mutually inner uncovered, the outer end shutoff; Preventing that through sheath link from being become flexible, being moved, thereby prevent that easy-stealing part is stolen.

The outer rim of said link end is provided with groove, and sheath cavity wall face correspondence is provided with matched groove, is provided with spring ring in the groove after connecting, so that after sheath is connected on the link, fix through spring ring.

Said link is a connecting pin, perhaps bolt, perhaps nut, perhaps connecting rod, perhaps screw rod, perhaps plug etc.

The utility model compared with prior art has advantage and effect: adopt such scheme, can through spring ring sheath be connected on the link easily, sheath can only be rotated along the link periphery; And can't move axially; Prevent that effectively link from being become flexible, being moved, so prevent be prone to steal parts or part stolen, and do not influence frequent the coming and going of long distance and move; Need not to be equipped with special tool, and can guard against theft multiple demountable structure.

Fig. 2 is another structural representation of the utility model;

Fig. 3 is a structural representation again of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

The antitheft connection set that the utility model provides comprises link, and this link is a connecting pin 1; Be prone to steal parts 2 through 1 pair of open air of connecting pin and fix, connecting pin 1 end after fixing and band cavity 5 and sheath 4 clamping mutually inner uncovered, the outer end shutoff in it, wherein; The outer rim of connecting pin 1 end is provided with groove 7, and sheath 4 cavitys 5 wall correspondences are provided with matched groove 3, are provided with spring ring 6 in the groove after connecting; So that sheath 4 is fixed through spring ring 6 after being connected on the connecting pin 1, and sheath 4 can only be rotated in connecting pin 1 end; Can not move axially, like Fig. 1.

Said link is a nut 9, is prone to steal parts 2 through bolt 1,

nut

9 and 8 pairs of open airs of packing ring and fixes, nut 9 ends after fixing and band cavity 5 and sheath 4 clamping mutually inner uncovered, the outer end shutoff in it; Sheath 4 can only be rotated in nut 9 ends; Can not move axially, and no matter use which kind of instrument all can't become flexible or travelling nut, thus effectively antitheft; Like Fig. 2, the same Fig. 1 of all the other structures.

Said link is a screw rod 11; Through nut 10 open air being prone to steal parts 2 is fixed on the screw rod 11; Screw rod 11 ends after fixing with its in band cavity and sheath 4 clamping mutually inner uncovered, the outer end shutoff, and sheath 4 can only the rotation in screw rod 11 ends, can not move axially; Like Fig. 3, the same Fig. 1 of all the other structures.

Claims

1. an antitheft connection set comprises link, it is characterized in that interior band cavity of link end and its and sheath clamping mutually inner uncovered, the outer end shutoff.

2. antitheft connection set according to claim 1 is characterized in that the outer rim of said link end is provided with groove, and sheath cavity wall face correspondence is provided with matched groove, is provided with spring ring in the groove after connecting.

3. antitheft connection set according to claim 1 is characterized in that said link is a connecting pin, perhaps bolt, perhaps nut, perhaps connecting rod, perhaps screw rod, perhaps plug.
