Abstract

The utility model discloses an anti-theft type pipe caliper and the wrench, wherein, the upper case body of the pipe caliper is provided with a concave hole in which a screw nut or a screw bolt head can be embedded; the screw nut connected with a dog screw bolt is a five square screw nut; a screw thread hole can be drilled on the lower case body, and the upper and the lower case body is fastened with the screw bolt with five square heads by the screw thread hole; the sleeve wrench used for anti-theft type pipe caliper is provided with five square holes matched with the external five square of the head of the five square screw nut or the screw bolt with five square heads; because the head of the five square screw nut or the screw bolt with five square heads sinks in the concave hole of the upper case body, an ordinary wrench can not detach, and water supply pipes can be effectively prevented from stealing. The utility model is suitable for the water supply pipes of petroleum and drilling engineering.

Description

Anti-theft pipe clamp and spanner thereof

The utility model relates to a kind of anti-theft pipe clamp and spanner thereof that water supply line connects fastening usefulness that be used for.

Existing common pipe clamp is by upper shell, standard piece six square nuts, and parts such as swing bolt, axle, packing ring, back-up ring, lower shell body are formed; Structurally fastening piece exposes, and general purpose tool is promptly detachable, can not be antitheft; Nut separates with packing ring, and execute-in-place is very inconvenient.

The purpose of this utility model is that to design a kind of nut or screw head be five sides and imbed anti-theft pipe clamp and spanner thereof in the upper shell in order to overcome above-mentioned deficiency, and theftproof performance is fine.

The purpose of this utility model is achieved through the following technical solutions: the anti-theft pipe clamp is made up of upper shell, lower shell body, nut, bearing pin and swing bolt, and upper shell is provided with the shrinkage pool that nut or screw head are imbedded.

The described nut that is connected with swing bolt is outer five square nuts, and this nuts and washers makes and is structure as a whole.

Also can bore the tap out hole on lower shell body, by this tapped hole and bolt that upper and lower casing is fastening, the screw head of described bolt is outer five sides, and the head of outer five square head bolts can be imbedded in the shrinkage pool of upper shell.

The sleeve that is used for the spanner of antitheft pipe clamp is provided with interior five square holes that match with five square nuts or five square bolt heads.

The utility model advantage, because the tightening nut of antitheft pipe clamp or the head of bolt are imbedded in the shrinkage pool of upper shell, the head making and settlement of nut or bolt are square for outer five, general hexagon or adjustable wrench can't be dismantled, must use non-standard interior five square box socket wrench to load and unload, guaranteed that petroleum drilling engineering supplies water and ordinary production, has improved the economic benefit of drilling engineering.
