Embodiment Construction

[0031] In the following, the test fixture will be further described in detail mainly in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as Figure 1 ~ Figure 3 As shown, the test fixture 100 of this preferred embodiment is mainly used to fix the impact test piece (hereinafter referred to as the test piece) of the lamp during the impact test of the lamp, such as the lamp housing, the transparent piece, etc., so as to facilitate different angles of the impact test piece. Multi-point impact testing to find the weak point of the test piece. The test fixture 100 includes a base 110 , a first limiting component 120 , a fixing post 130 , a movable rod 140 and a second limiting component 150 . After being placed on the base 112 , the test piece can abut against between the first limiting member 120 and the second limiting member 150 to be fixed.

[0033] Wherein, the base 110 of this embodiment is preferably made of a square steel plate, such as a ...

Abstract

The invention relates to a fixing device used in testing. The fixing device is used for fixing a lamp testing member and comprises a base, a first limiting member movably arranged on the base, a fixed pillar fixed on the base, a movable rod movably arranged on the fixed pillar and a second limiting member connected with one end of the movable rod, wherein the movable rod can swing axially around the fixed pillar. When the fixing device is used, an impact testing member can be placed in the middle of the fixing device, then users can adjust the first limiting member and the movable rod and fix the impact testing member among the base, the first limiting member and the second limiting member, and in terms of an irregular testing member, the users can adjust the angle between the first limiting member and the base by adjusting the movable rod and then perform impact testing. The fixing device used in testing is convenient to adjust and simple and practicable in the testing process, can perform different-angle and different-point impact testing on the irregular testing member, can enable the users to find out weak points of the testing member conveniently and is firm to fix and high in reliability.

Description

【Technical field】 [0001] The invention relates to a fixing device, in particular to a test fixing device capable of fixing an impact test piece of a lamp. 【Background technique】 [0002] In the field of professional lighting, explosion-proof lamps must be subjected to impact tests. The transparent part of the luminaire is the key test part and the weakest part of the electrical equipment enclosure. The rupture of the transparent part will directly invalidate the explosion-proof lamp. The purpose of the impact test is to verify whether the transparent parts of the lamp can effectively withstand the impact. Shock test means that electrical equipment should withstand the impact of a test object with a mass of 1Kg falling vertically from a certain height. Generally speaking, the impact test pieces of different lamps have different shapes, such as spherical, hemispherical, rectangular, etc. Various special-shaped test pieces correspond to different weak points. Because there ...
