A push-type lamp holder structure

Abstract

The invention discloses a press type lamp cap structure which comprises a lamp cap, a pressing part, electrical connection terminals, and a reset spring, wherein flanges are formed on the periphery of the end face of the lam cap in an encircling manner; a penetrating hole is formed in the center of the lamp cap in a penetrating manner; a position clamping block is arranged on the inner wall of the periphery of the lamp cap; a plurality of run-through position clamping slots are formed in the position clamping block; the pressing part is provided with a penetrating column; the penetrating column is arranged in the penetrating hole in a penetrating manner; a limiting clamping hook is arranged at the bottom of the penetrating column, and can be propped against the wall surface of the bottom of the pressing part in a clamping manner to prevent the pressing part from falling; a position clamping block is arranged on the penetrating column in a protruded manner, and can be embedded into the position clamping slots to enable the lamp cap and the pressing part not to rotate relative to each other; the electrical connection terminals are arranged on the pressing part to be connected with an external power supply for power supply; the reset spring sleeves the penetrating column in a penetrating manner; the two ends of the reset spring are respectively propped against the pressing part and the lamp cap end face, so that reset elastic force can be provided for the pressing part to enable the pressing part to move outwards until the limiting clamping hook is propped against the bottom wall of the penetrating hole. According to the invention, when the pressing part is pressed downwards, the position clamping block is separated from the position clamping slots to allow the lamp cap to rotate by a preset angle relative to the pressing part.

Description

technical field [0001] The present invention relates to the related technical field of LED lamps, and more specifically relates to a fixing mechanism for a lamp head that is both fastening and convenient to twist. Background technique [0002] Light-emitting diodes, hereinafter referred to as LEDs, have been widely used in various fields of people's lives due to their characteristics of power saving, high luminous efficiency, and environmental protection. For example: indoor lighting in homes or offices, outdoor street lighting, and even lighting components inside electronic devices (such as LCD backlight modules), etc., all use LEDs. [0003] Among them, in terms of indoor lighting, in order to achieve better lighting effects, the industry has conducted in-depth research on LED lamp modules and developed various forms of LED lamps. LED light tubes have replaced traditional fluorescent tubes and become household lighting fixtures commonly used by people. [0004] When the ...
