By retrieval, do not have to find relevant patent document.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and freely can be elevated the convenient for maintaining of lamp holder and change the view lamp stand of fluorescent tube.
The object of the invention is to be achieved through the following technical solutions:
The view lamp stand of a kind of convenient for maintaining and replacing fluorescent tube, comprise lamp stand base, lamp stand and lamp holder, lamp stand base upper end is coaxially fixedly mounted with lamp stand, the upper cantilever arm of lamp stand installs lamp holder, it is characterized in that: the lamp holder that described lamp stand upper cantilever is installed is upper and lower lift, when lamp holder is raised to top, the lamp holder plug in lamp stand inserts in the socket that in lamp stand, top is fixedly mounted with.
And, the structure of described lamp holder upper and lower lifting on lamp stand is: in lamp stand, be vertically fixedly mounted with a slide bar, this slide bar is coaxially slidably installed a linear bearing, the upper end of slide bar is packed on the top cover that lamp stand top is fixedly mounted with, and the lower end of slide bar is packed on the fixed head that radial direction in a lamp stand is fixedly mounted with; The lamp stand base of slide bar side installs a leading screw, and the upper end of this leading screw is arranged on the top cover that lamp stand top is fixedly mounted with by upper bearing (metal), and the lower end of leading screw is arranged on the fixed head in lamp stand by lower bearing; The lower end hinge of leading screw fills a universal joint, the lower end of this universal joint is coaxially connected with a umbrella shape pinion, this umbrella shape pinion is meshed with the radial umbrella shape master gear be arranged on lamp stand base, and this umbrella shape master gear is coaxially fixedly connected with by the crank outside lamp stand base; Leading screw in lamp stand engages silk braid in installation one, this interior silk braid is fixedly connected with the connection handle of lamp holder by slideway vertically made on lamp stand, internal thread to be enclosed within lamp stand and to be also fixedly mounted with diametrically with the linear bearing installed on slide bar, a plug is fixedly mounted with straight up at the binding site of linear bearing and interior silk braid, to being fixedly mounted with a socket in the lamp stand top cover of plug, when internal thread cover drives plug to rise to lamp stand top, switch on power in plug insertion socket.
Advantage of the present invention and good effect are:
1, the upper design of this lamp stand has movable fixture, can make lamp holder oscilaltion, is therefore elevated lamp holder when keeping in repair by handle, facilitate maintenance and change light fixture, reducing the danger changed and keep in repair, and when keeping in repair and change light fixture, convenient and swift, improve operating efficiency.
2, this lamp stand adopts leading screw mode to carry out the lifting of lamp holder, and overall structure is ingenious, design science is reasonable, solves the problems of existing lamp stand existence, is specially adapted to river bank, all kinds of scenic spot, the street lamp of residential quarter and Landscape Lamp.
3, this lamp stand is after decline, can disconnect socket switch, can ensure safety thus, avoids maintenance personal to be shocked by electricity, and protection is good.
4, this lamp stand is designed with straight-line guidance bearing, and it is convenient, fast with coordinating of leading screw; Wherein the connection of leading screw and umbrella shape pinion adopts universal joint, is very easy to installation, reduces cost simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are further described; The present embodiment is descriptive, is not determinate, can not limit protection scope of the present invention thus.
The view lamp stand of a kind of convenient for maintaining and replacing fluorescent tube, comprise lamp stand base 7, lamp stand 4 and lamp holder 2, lamp stand base and lamp stand adopt steel pipe manufacturing, and lamp stand base upper end is coaxially fixedly mounted with lamp stand, the upper cantilever arm of lamp stand installs lamp holder, and lamp stand base is designed with hand hole door 6.
Innovative point of the present invention is:
The lamp holder that described lamp stand upper cantilever is installed is upper and lower lift, and when lamp holder is raised to top, the lamp holder plug in lamp stand inserts in the socket that in lamp stand, top is fixedly mounted with.
The structure of described lamp holder upper and lower lifting on lamp stand is:
In lamp stand, be vertically fixedly mounted with a slide bar 10, this slide bar is coaxially slidably installed a linear bearing 11, and the upper end of slide bar is packed on the top cover 1 that lamp stand top is fixedly mounted with, and the lower end of slide bar is packed on the fixed head 15 that radial direction in a lamp stand is fixedly mounted with.
The lamp stand base of slide bar side is installed a leading screw 14, and the upper end of this leading screw is arranged on the top cover that lamp stand top is fixedly mounted with by upper bearing (metal) 9, and the lower end of leading screw is arranged on the fixed head in lamp stand by lower bearing 16; The lower end hinge of leading screw fills a universal joint 17, the lower end of this universal joint is coaxially connected with a umbrella shape pinion 18, this umbrella shape pinion is meshed with the radial umbrella shape master gear 19 be arranged on lamp stand base, this umbrella shape master gear is coaxially fixedly connected with by the crank 5 outside lamp stand base, realize when adopting crank to rotate umbrella shape master gear thus, umbrella shape master gear engagement umbrella shape pinion, umbrella shape pinion drives screw turns by universal joint.
Leading screw in lamp stand engages silk braid 13 in installation one, this interior silk braid is fixedly connected with the connection handle of lamp holder by slideway 3 vertically made on lamp stand, internal thread to be enclosed within lamp stand and to be also fixedly mounted with diametrically with the linear bearing installed on slide bar, realize thus leading screw drive internal thread cover on, bottom offset time, linear bearing play the guiding role, to be elevated lamp holder reposefully.Be fixedly mounted with a plug 12 straight up at the binding site of linear bearing and interior silk braid, to being fixedly mounted with a socket 8 in the lamp stand top cover of plug, when internal thread cover drives plug to rise to lamp stand top, switch on power in plug insertion socket.
