Telescopic underground lamp

Abstract

The invention provides a telescopic underground lamp, and belongs to the technical field of lamps, which solves the problems of unsmoothness in up-and-down sliding and low reset accuracy of an existing underground lamp. The telescopic underground lamp comprises a barrel and a lamp body, wherein the lamp body is arranged in the barrel in an up-and-down sliding mode, the barrel comprises a barrel body and a limiting sleeve which is removably connected to the upper end of the barrel body, the upper end of the limiting sleeve is turned inwards so as to form inward flanging, the upper end of the lamp body is abutted with the inward flanging, a fixed pipe which is vertically arranged is arranged on the inner bottom surface of the barrel body, the fixed pipe penetrates through the bottom surfaceof the barrel body, a guide pipe of which the lower end extends into the fixed pipe is arranged in the middle of the lower end surface of the lamp body, a spring I which sleeves the guide pipe is arranged between the upper end surface of the fixed pipe and the lower end surface of the lamp body, and a plurality of springs II are arranged between an annular bulge I and an annular bulge II. According to the structure, the lamp body smoothly slides up and down, and the reset is accurate.

Description

technical field [0001] The invention belongs to the technical field of lamps, in particular to a retractable underground lamp. Background technique [0002] In municipal roads and some garden roads, buried lights are usually installed. Because the buried lights are flush with the ground, pedestrians or vehicles will crush the buried lights. If things go on like this, the lamp experience of the entire buried lights Suffering damage will affect the service life of the buried lamp. [0003] At present, in order to deal with the above situation, there is a retractable underground lamp on the market. The underground lamp is slidably sleeved in an outer casing, and an elastic mechanism is arranged in the outer casing to make the underground lamp have a tendency to slide upward. When people walk by or vehicles pass by, they will crush the buried lights, and the buried lights will slide down against the force of the elastic mechanism to prolong the service life of the buried lights...

Problems solved by technology

[0002] In municipal roads and some garden roads, buried lights are usually installed. Because the buried lights are flush with the ground, pedestrians or vehicles will crush the buried lights. If things go on like this, the lamp experience of the entire buried lights Damaged, affecting the service life of buried lights

[0003] At present, in order to deal with the above situation, there is a retractable underground lamp on the market. The underground lamp is slidably sleeved in an outer casing, and an elastic mechanism is arranged in the outer casing to make the underground lamp have a tendency to slide upward. When people walk by or vehicles pass by, they will crush the buried lights, and the buried lights will slide down against the force of the elastic mechanism to prolong the service life of the buried lights. However, the traditional elastic mechanism makes the buried lights slide upwards. It is easy to get stuck, which affects the use of buried lights
