Handheld detonating pipe achieving surface blasting

Abstract

The invention discloses a handheld detonating pipe achieving surface blasting. The handheld detonating pipe comprises buffer pads, a detonator, a base clamp sleeve and detonating pipe bodies. The buffer pads are fixedly arranged at the upper end and the lower end of the detonator. The lower end of the detonator is sleeved with the base clamp sleeve. The base clamp sleeve is composed of a left baseclamp sleeve body and a right base clamp sleeve body. In the device, the detonating pipe bodies only need to be tucked in from a placement door, the placement door controls a sealing arc plate to beopened by pulling a pull plate, and use is convenient; the detonating pipe bodies are tucked into placement grooves corresponding to the position between an inner-layer rubber moving ring and an outer-layer rubber moving ring in the base clamp sleeve, and the buffer performance around the detonating pipe is good; a hard supporting ring is movably attached to the inner ring of the base clamp sleeve, the base clamp sleeve can be rotated every time one detonating pipe body is mounted, and the next detonating pipe body is mounted in the corresponding adjacent placement groove; and mounting and operation are convenient, and safety is high.

Description

technical field [0001] The invention relates to the technical field of hand-held detonators used for open-air blasting of buildings, in particular to a hand-held detonator for open-air blasting. Background technique [0002] The patent application number is: 201710314710.5, and the patent name is: A detonator network quick wiring device. The gap between the outer wall of the detonator ferrule part and the inner wall of the base ferrule is adapted to the detonator. Multiple detonators can be set in the gap between the outer wall of the ferrule part and the inner wall of the base ferrule, which can quickly fix the detonator around the detonator, and the position between the detonator and the detonator is determined, and the operation is convenient and quick. The following disadvantages still exist in actual use: [0003] 1. The installation of the detonator in the device is inconvenient. It is necessary to fit the detonator wall along the vertical direction of the ferrule of ...

AI Technical Summary

Problems solved by technology

[0003] 1. The installation of the detonator in the device is inconvenient. It is necessary to fit the detonator wall along the vertical direction of the ferrule of the base to insert the detonator. The operation needs to be cautious and inconvenient to use;

[0004] 2. When the detonators in the device are tied together, they are easy to influence each other, and they need to be handled with care when they are put into the hole for blasting buildings, and it is very likely that the detonators will fail or cause safety accidents due to extrusion, scratches and other phenomena. less secure
