Description

A kind of extension type underground lamp

Technical field

The invention belongs to technical field of lamps, especially a kind of extension type underground lamp.

Background technology

In town road and some garden paths, it will usually underground lamp is set, underground lamp due to concordant with ground, Pedestrian passes by or has vehicle by can be rolled by underground lamp, if things go on like this, the lamp body of entire underground lamp can by destruction, Influence the service life of underground lamp.

Currently, in order to cope with the above situation, occur a kind of underground lamp of extension type on the market, underground lamp sliding is arranged In an outer sleeve body, elastic mechanism is set in outer sleeve body to make underground lamp have the trend of upward sliding, when pedestrian walks It crosses or has vehicle by when can all be rolled by underground lamp, underground lamp overcomes the active force slide downward of elastic mechanism, prolongedly The service life of lamp is buried, but elastic mechanism traditionally makes underground lamp be susceptible to stuck problem in upward sliding, Influence the use of underground lamp.

Invention content

The purpose of the present invention is there is the above problem in view of the prior art, it is proposed that a kind of extension type underground lamp, this The technical problems to be solved by the invention are：Reseting precision is improved while the smoothness for how improving underground lamp reset.

Object of the invention can be realized by the following technical scheme：A kind of extension type underground lamp, including staving and edge Slide up and down the lamp body being arranged in staving, which is characterized in that the staving includes ladle body and is detachably connected on ladle body upper end Stop collar, the upper end of the stop collar is formed with in-flanges to varus, and the upper end of the lamp body is resisted against on in-flanges, described There is vertically arranged fixing pipe, the fixing pipe to be arranged through the bottom surface of ladle body on the inner bottom surface of ladle body, the lamp body There is lower end to extend to the guide pipe in fixing pipe at the middle part of lower face, the upper surface of the fixing pipe and the lower face of lamp body it Between have and be set in spring one on guide pipe, there is annular protrusion one, the inside of the ladle body on the peripheral surface of the lamp body There is the annular protrusion two for being located at one lower section of annular protrusion on wall, have between the annular protrusion one and annular protrusion two several A spring two, circumferentially-spaced arrangement of several springs two along ladle body.

In the structure, guide pipe is slidably arranged in fixing pipe, and the assembling structure of guide pipe and fixing pipe is under lamp body Guiding is played the role of in shifting so that entire lamp body is slidably arranged in staving, and spring one and two one side of spring form lamp body Multi-point support, lamp body uniform force and the trend for maintaining upward sliding, for lamp body after by external force, lamp body overcomes one He of spring The active force of spring two moves down, and lamp body moves down stabilization under the guiding of guide pipe, and after external force disappears, lamp body is in spring one It is resetted with upward sliding under the action of spring two, due to the whole uniform force of lamp body, and under the guiding of guide pipe, lamp body begins It moves up and down, will not be slided up and down there is a situation where position offset, lamp body smooth and resets accurately along the axial direction of guide pipe eventually.

In a kind of above-mentioned extension type underground lamp, the upper table of the lower surface and annular protrusion two of the annular protrusion one Face all has pillar, and the upper and lower side of the spring two is set on corresponding pillar.The structure plays positioning to spring two Effect.

In a kind of above-mentioned extension type underground lamp, the lower end of the stop collar has a lower flange, the ladle body it is upper End has upper overturning, is connected by several fasteners between the lower flange and upper overturning, several fasteners are along ladle body It is provided at circumferentially spaced.The structure ensures that stop collar and ladle body are fixed, and lamp body is withstood under the action of spring one and spring two Stop collar is avoided to generate loosening on in-flanges；And after underground lamp installation, upper surface and the ground flush of underground lamp, and ladle body There is certain distance, the connection structure to be embedded under soil for connection structure to the upper surface of underground lamp between stop collar, improve The aesthetics of underground lamp, when needing to lamp body detachable maintaining, it is only necessary to which stop collar can be dismantled by pushing one layer of very thin soil aside, side Just to the repair of lamp body or replacement.

In a kind of above-mentioned extension type underground lamp, the lamp body further includes having power cord, and the power cord is worn successively It crosses guide pipe and fixing pipe and is pierced by from the bottom of ladle body.

In a kind of above-mentioned extension type underground lamp, the upper end outer edge of the lamp body has chamfering, the in-flanges It is upper that there is the taper surface to match with chamfering.

Compared with prior art, extension type underground lamp of the invention has the following advantages：The dress of guide pipe and fixing pipe Distribution structure plays the role of guiding to moving down for lamp body, and spring one and two one side of spring form multi-point support, lamp body to lamp body Whole uniform force, and under the guiding of guide pipe, lamp body is moved up and down along the axial direction of guide pipe always, and position will not occur The case where offset, lamp body are slided up and down smooth and are resetted accurately.
