Abstract

A delay element used for a millisecond detonator and a 1/4-second delay electric detonator consist of a delay element frame, delay composition and a delay electrode. The utility model is characterized in that the delay element frame is cylinder shape, a through hole is arranged at the center of the delay element frame, a conical hole serves as the left segment of the through hole and a column-shaped hole serves as the right segment of the through hole; the delay composition is filled in the hole of the right segment, and the electrode is placed in the hole of the left segment. The utility model has the advantages of simple structure, low cost and convenient use and the plastics are adopted as the materials of the delay element frame, thereby lowering the production cost and preventing the environmental contamination.

Description

Millisecond detonator and 1/4 second delay electric detonator extension body

One, technical field

The utility model relates to a kind of device in the detonator, and particularly a kind of millisecond detonator and 1/4 second delay electric detonator are used " extension body ".

Two, background technology

Lead system extension body in present millisecond detonator or 1/4 second delay electric detonator, complex manufacturing, contaminated environment, weight is big, the cost height, this is the deficiencies in the prior art.

Three, summary of the invention

The purpose of this utility model is a kind of millisecond detonator of invention and 1/4 second delay electric detonator extension body, and this extension body structure is simple, and production technology is simple, adopt common plastics or flame retardant plastics to make, thereby cost is low, and is free from environmental pollution, in order to overcome existing deficiency with plumbous system extension body.

The purpose of this utility model can reach by following embodiment: this extension body is made up of extension body frame, delay powder and extension electrode, extension body frame profile is a cylinder, there is through hole at its center, the left side section of through hole is a bellmouth, right section is a cylindrical hole, put delay powder in the right sector hole, discharge electrode in the left sector hole.

Section is bellmouth about the through hole of extension body frame of the present utility model, and the position that delay powder is placed can be left side section or right section.

The material of extension body frame of the present utility model is that common plastics or flame retardant plastics are made.

Advantage of the present utility model is simple in structure, cheap, easy to use, adopts common plastics or flame retardant plastics to reduce production costs, and prevents the pollution of the environment, and can produce allowed for use in coal mines millisecond detonator or 1/4 second delay electric detonator.
