Description

TECHNICAL FIELD

[0001] The utility model relates to electric detonator test tool field, concretely is a general electric detonator insulation resistance test tool. BACKGROUND

[0002] In electric detonator performance test, usually use performance test tool to simulate electric detonator actual use environment, thereby examine whether the performance of product can satisfy the technical requirement. The existing electric detonator insulation resistance test technology has the following shortcomings:

[0003] 1, when using insulation resistance tester to test electric detonator insulation resistance, need to repeatedly clamp electric detonator foot line and electric detonator shell, the shell appearance size of electric detonator is different, and the shell of most electric detonators is not easy to clamp, thereby causing the scratch damage of shell when the test clamp of insulation resistance tester is on the shell of electric detonator, and other problems, resulting in that after the insulation resistance measurement is finished, a lot of electric detonators are judged as unqualified products due to the appearance not meeting the requirements.

[0004] 2, the existing electric detonator insulation resistance test technology cannot achieve complete and effective safety protection. In the electric detonator insulation resistance test process, there is the possibility of accidental firing, and the detonation and explosion fragments caused by accidental firing of electric detonator will splash around, which will cause harm to the inspection personnel if they cannot avoid in time. INVENTION CONTENTS

[0005] The utility model provides a general electric detonator insulation resistance test tool to solve the problem of easy damage and poor safety in the electric detonator insulation resistance test of prior art.

[0006] In order to achieve the above purpose, the technical scheme adopted by the utility model is:

[0007] A general electric detonator insulation resistance test tool, characterized by comprising a box body with a box cover, a base is placed in the box body, the base is a circular arc columnar structure, the central angle of the circular arc of the circular arc columnar structure is greater than or equal to 90 degrees, a measuring clamp is placed in the central circular arc hole of the circular arc columnar structure, the measuring clamp comprises a copper column and a copper rod connected to the axial one end of the copper column, and a central recess is arranged in the copper column axially at the other end of the copper column.

[0008] Further, the base is made of cloth plywood material.

[0009] The utility model discloses, adopt the cloth plywood as the base of fixed measuring fixture, the base of fixed measuring fixture is put into the box, then the measured electric detonator is put into the center recess of measuring fixture, and the two wires of insulation resistance tester are connected with the copper bar of measuring fixture and the short circuit after foot line of measured electric detonator, can measure the insulation resistance of measured electric detonator.

[0010] Compared with the prior art, the utility model has the advantages of:

[0011] 1, the utility model discloses electric detonator insulation resistance test tooling can cover company all kinds of electric detonator insulation resistance measurement, solved the problem of the shell of electric detonator and not easy to clamp thereby leading to the scratch damage of shell when the test line of insulation resistance tester is clamped on the shell of electric detonator.

[0012] 2, the utility model discloses electric detonator insulation resistance test tooling solved the problem of personal injury of the tester in the process of measuring electric detonator insulation resistance because of the accidental firing of electric detonator. BRIEF DESCRIPTION OF DRAWINGS
