Description

Easily adjust the light fixture of length

[technical field]

The utility model relates to a kind of light fixture of easy adjustment length, is meant that especially a kind of suspention of light fixture highly can adjust and have the mechanism of aesthetic property.

[background technology]

The light fixture of known major part all is a regular length, as shown in Figure 1, is a kind of light fixture of suspension type, does not have height arm control on its structure, can not reach the function of suspention height-adjustable; Lie in ceiling 1 top and be positioned with a transformer 11, meet an electric wire 12 to one lamp bodies 13 places by transformer 11, and electric wire 12 is one of to pass on the ceiling 1 hole 10, more be fixed with a location-plate 14 in the bottom surface of ceiling 1, location-plate 14 also has a perforation 15 with respect to hole 10, so the weight of lamp body 13 is born by electric wire, but how long just electric wire 12 has how long to hang, but the length of electric wire 12 is fixing immutable, if will adjust, can only on electric wire, tie a knot, and this knotting place need be positioned at ceiling 1 top; This shows that known person does not have length adjusting mechanism; For more realistic demand article are provided, the creator researches and develops, and can't adjust the problem of length to solve known light fixture.

Because known is directly to quote electric wire with the suspention light fixture, this moment, known problem promptly was to adjust overhang length only can carry out through electric wire knotting mode, adjust each time and all need to open ceiling, if still opening, the light steelframe type asbestos slate of office adjusts, if generally adorning the ceiling of spring type then can't open, can only partly adjust with knotting mode or similar mode in the electric wire that exposes, all be to be subjected to ceiling structure system, can't optionally adjust at any time; Hence one can see that, known shortcoming arranged structurally, shortcoming is also arranged in assembling, bigger shortcoming is arranged in the use, shortcoming especially on overall appearance; For the article of more realistic demand are provided, the creator researches and develops, the various shortcomings that can produce during with the adjustment that solves known light fixture.

[summary of the invention]

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part and light fixture that easy adjustment length is provided, the overhang length of light fixture can be adjusted, so the user can carry out the adjustment of electric wire overhang length at any time according to need, mainly utilize in one pair, the action that the inclined-plane of package assembly slides, and carry out the action of blocking by at least one limited part, allow and regulate rope yarn slippage and location in internal member, as long as the user pushes away the action that internal member can be adjusted, it is a beautiful appearance with the known characteristic of comparing, no unnecessary outstanding electric wire and lines, and each part is easy to processing and manufacturing, cost is low, can assemble easily, and each assembly is all in package assembly, in manipulating, have more security, the situation of falling in the time of can not adjusting, and limited part is better with the polarization of regulating rope yarn to internal member, limited part is pressed on fully regulates on the rope yarn, and internal member is smooth and easy to the slip of package assembly, and the protruded length one of regulating rope yarn is adjusted to set and finishes, and just can promote the action that internal member restores naturally with elastic component, make the polarization of regulating rope yarn better, in addition, be provided with fixture also convenient with the engaging of ceiling, allow this creation be easier to assemble.

The purpose of this utility model can reach by following measure:

The light fixture of this easy adjustment length, its special character is: comprising: a lamp body; Reach one and regulate rope yarn, one is terminated at lamp body;

One control agent, it is connected to the other end of regulating rope yarn, regulates rope yarn and passes control agent, and control agent has a package assembly, an internal member, at least one limited part, an elastic component, a location ring plate and a fixture; Package assembly is for being positioned a fixture, fixture is for being positioned the ceiling place, one hole is arranged in the fixture, package assembly lower end inner face has tapering in, internal member have one outstanding outside the tapering, heart channel allows the adjusting rope yarn pass through among the outer tapering, and make the adjusting rope yarn pass the hole of fixture, and outer tapering is for being posted by interior tapering, outer tapering is provided with the number redial perforation, each radial perforation and central channel connect, and in each radial perforation a limited part are arranged respectively, contact with adjusting rope yarn appearance with limited part, the elastic component lower end joins with outer tapering, the elastic component upper end joins with fixed aunular sheet, fixed aunular sheet is positioned in the package assembly, and internal member is in package assembly, and distal process stretches out package assembly under the internal member.

The purpose of this utility model can also reach by following measure:

Its limited part is a ball.

Its elastic component is a spring.

It between its fixture and package assembly interlocking.

Its fixture is provided with at least one fastener, and a torque spring is contained at the two ends of fastener respectively, is buckled in the end face of ceiling with fastener.

The utility model has following advantage compared to existing technology:

Package assembly 41 appearances need not to combine with other assembly, outward appearance is neatly beautiful, can form the tapering shape of lower end on making naturally, more convenient processing, during assembling, as long as internal member 42 is penetrated package assembly 41 interior location naturally together with limited part 44, insert elastic component 45 back interlocking Location resilient pieces 46 again, allow Location resilient piece 46 be hidden in the package assembly 2, penetrate this adjusting rope yarn 3 at last, connect the operation of electric wire, then indivedual handling eases of each assembly, most particularly, 44 pairs of power of tightening of regulating rope yarn 3 of limited part, can reach maximum, be subjected to holding of inner conical surface fully, also therefore show different with known maximum, the moving process of limited part does not leave the conical surface partly, reach best controlled with this, another characteristic makes the assembling of the utility model and ceiling easier for having fixture 43, also make the durability of integral body better, so the utility model can provide fine usability, be one fully with known different mechanism.
