Description

A kind of telescopically adjustable desk lamp

Technical field

The utility model relates to desk lamp product technical field, especially a kind of telescopically adjustable desk lamp.

Background technique

Desk lamp is one kind of lamp, and small and exquisite exquisiteness is mainly located on desk or dining table, so that illumination is used.At present Desk lamp on the market includes that pedestal, first body of rod and second body of rod are constituted mostly, and first body of rod is loaded on pedestal by support hinge, And one end of second body of rod and first body of rod are hinged, and lamp cap is equipped on second body of rod, pass through the phase of first body of rod and pedestal To rotation and first body of rod and second body of rod relative rotation with to lamp cap progress telescopic adjustment, so that desk lamp is obtained different irradiations Angle, to meet user to the application demand of different scenes, the desk lamp of this structure needs to turn use before and after adjusting every time In screw hingedly, use so highly inconvenient.

In order to solve deficiency above-mentioned, also occur on the market now it is some can not have to turn screw just and can be carried out it is flexible The desk lamp of adjusting, the desk lamp of this spline structure is mostly such as China Patent Publication No. CN204513077U, entitled " Telescopic adjustable Technical solution described in desk lamp " is such, including pedestal, card slot, telescopic rod, oblique pull spring, universal bearing, lamp cap and bracket, institute It states bracket to be made of two parallelogram frame bodies, parallelogram frame body one is vertically arranged, and parallelogram frame body two is laterally Setting, two parallelogram frame bodies are connected on two radiuses of a fan-shaped attachment device；The parallelogram frame body A hinge joint and telescopic rod for one bottom is hinged；The telescopic rod is threadedly coupled with the card slot being fixed on pedestal；It is described parallel The third end of the hinged triangular supporting frame in the free end of quadrangle frame body two, triangular supporting frame is equipped with universal bearing, institute Lamp cap is stated to connect with universal bearing；Oblique pull spring is separately connected between two long sides of described two parallelogram frame bodies.This Spline structure is cooperated using oblique pull spring and parallelogram frame body, and desk lamp user when being adjusted is made only lamp cap need to be pulled to carry out It adjusts, and parallelogram frame body can realize positioning automatically under the effect of oblique pull spring after lamp cap adjusting in place, and then reach not Needing to lock screw can be to the purpose that lamp cap is adjusted, and there is also following deficiencies for the desk lamp of this spline structure: first is that, oblique pull spring Be it is exposed, aesthetics is poor, and oblique pull spring also be easy hiding dirt, it is difficult to clear up；Second is that using parallelogram frame body Cooperation with oblique pull spring carries out telescopic adjustment, and one side structure is complex, assembling difficulty is big, and on the other hand parallel four Side shape frame body be also it is exposed, mechanical structure intuitive in this way is more raw and cold to the feeling of user, cannot bring to user Warm feeling, is unsatisfactory for the demand of user.

Utility model content

The purpose of this utility model is to provide a kind of telescopically adjustable desk lamp, which has knot Structure is simple, design is reasonable, easy to use, cleans easy, beautiful and can be hidden mechanical part, can build temperature to user The advantages that fragrant atmosphere.

The technical solution of the utility model is achieved in that a kind of telescopically adjustable desk lamp, including pedestal, support, First body of rod, hinged seat, second body of rod, lamp cap；The support is mounted on the base；One end of first body of rod and support phase Hingedly, the hinged seat is fixed in the other end of first body of rod；One end of second body of rod is hinged with hinged seat, should The other end of second body of rod is connect with the lamp cap；It is characterized in that further including the first tension spring, the second tension spring, the first sliding block, Two sliding blocks, the first pull rod, the second pull rod；Slideway is each formed in first body of rod, second body of rod；First sliding block and First tension spring is mounted in the slideway of first body of rod；On one end of first tension spring and first body of rod close to hinged seat that End is connect in relatively fixed setting, the other end of the first tension spring with the first sliding block；Second sliding block and the installation of the second tension spring In the slideway of second body of rod；One end of second tension spring and that one end of lamp cap close on second body of rod are in relatively fixed Setting, the other end of the second tension spring are connect with the second sliding block；Lug boss is each formed on the support, hinged seat；Described Lug boss on one end and support of one pull rod is hinged, and the other end is stretched in the slideway of first body of rod and mutually cut with scissors with the first sliding block It connects；Lug boss on one end and hinged seat of second pull rod is hinged, and the other end stretches in the slideway of second body of rod with Two sliding blocks are hinged.

Further, it is formed with the first gap being connected to its slideway on first body of rod, the one of first pull rod End is hinged across the first gap and the first sliding block.

Still further, the second gap being connected to its slideway is formed on second body of rod, second pull rod One end passes through the second gap and is hinged with the second sliding block.

Again still further, one end of first tension spring is connected with hinged seat.

Again also still further, the lamp cap is connect by a rotation regulating mechanism with second body of rod；The rotation is adjusted Mechanism includes mounting base, rotation seat and 2 lock screws, and the mounting base is fixed on the end of second body of rod, in mounting base Upper formation is fluted；The rotation seat is installed, which is embedded in the groove of mounting base on the lamp cap；2 locks Tight respective one end of screw penetrates into groove from the two sides of mounting base respectively, and the end of 2 lock screws and rotation seat it Between be connected through a screw thread positioned so that rotation seat and mounting base are realized.

The utility model has the beneficial effects that the utility model is by using first body of rod and second for being each formed with slideway The body of rod, and the first sliding block, the first tension spring are hidden in the slideway with first body of rod, the second sliding block, the second tension spring are then hidden in In the slideway of second body of rod, such design order is not easy to hide dirt to the first tension spring, the second tension spring, and the need to be only wiped clean in cleaning One body of rod, second body of rod；In addition, when in use, user is during pulling lamp cap to reach predetermined position, the first pull rod The first sliding block is pulled to move in the slideway of first body of rod, order is positioned to the end of the first tension spring first body of rod of tension, and second Pull rod will pull the second sliding block and move in the slideway of second body of rod, enables to the second tension spring and tenses the end of second body of rod to determine Position does not need the utility model also need to tighten before and after lamp cap is adjusted by first body of rod hingedly on the support Screw and the screw that first body of rod and second body of rod are hinged together make the utility model have simple structure and reasonable design, make It is easy with convenient, cleaning, is beautiful and mechanical part can be hidden, the advantages that warm atmosphere can be built to user.
