Testing device for connecting strength of hanging rope of flashlight

Abstract

The invention discloses a testing device for the connecting strength of a hanging rope of a flashlight. The testing device comprises a bracket, a connector and a clamping mechanism, wherein the bracket comprises a base, a supporting column and a cross beam; the connector is used for connecting the hanging rope, and the connector and the clamping mechanism are respectively arranged on the cross beam; and the clamping mechanism is used for clamping the flashlight and comprises a fixed block, a sliding block and an elastomer. In testing, the hanging rope is connected on the connector and a flashlight body is clamped between the sliding block and the fixed block; the position of the fixed block can be adjusted along the length direction of the cross beam, so that the central axis of the flashlight body and the connector are positioned at the same position in the length direction of the cross beam; when the flashlight body falls to generate swinging, the interference with a supporting column can be avoided; when the fixed block moves, the sliding block also can move under the action of the elastomer, so that the flashlight body can not be loose; and when the sliding block is removed and the flashlight body falls, the dynamic impact of the sliding down of the flashlight on the hanging rope can be accurately simulated, so that the testing is accurate and effective. The whole testing device is simple in structure and convenient in processing and preparation.

Description

technical field [0001] The invention relates to a flashlight reliability test device, in particular to a flashlight lanyard connection strength test device. Background technique [0002] As a necessary electrical appliance, flashlight is indispensable in people's life. As a commonly used tool, it is unavoidable for a tool that is often held in the hand to slip from the hand. If the flashlight falls to the ground, the flashlight will be deformed or even directly damaged and cannot be used again. inconvenient. In order to avoid such incidents, some flashlight manufacturers equip the flashlight with a lanyard, which can be hung on the wrist during use to prevent the flashlight from slipping from the hand and falling to the ground during use. Therefore, the design of the connection strength of the lanyard of the flashlight has become one of the important parameters that must be considered in the design of the flashlight. [0003] At present, the detection of the connection st...

AI Technical Summary

Problems solved by technology

Therefore, the effect of the flashlight slipping on the lanyard is a dynamic impact, and the existing method can only detect the static pulling force of the lanyard, which is inconsistent with actual use. After this test, it cannot be proved that the strength of the lanyard of the flashlight meets the actual situation. Anti-drop requirements in use, and there is no test device that can accurately simulate the flashlight slipping situation in the prior art
