Abstract

The utility model relates to a spring folding lampshade, comprising a lampshade veil made of soft material and a lampshade support frame. The utility model is characterized in that the lampshade support frame comprises an upper support loop, a lower support loop and a spring. At least one support loop has a structure for being connected with the lamp. The spring is a compression spiral spring, the outline of which matches with the three-dimensional outline of the lampshade veil. The upper and the lower ends of the spring are connected with the upper support loop and the lower support loop. The upper diameter and the lower diameter of the spring are respectively equal to the upper end diameter and the lower end diameter of the lampshade veil. The upper end and the lower end of the veil are fixed on the upper support loop and the lower support loop of the spring. The lampshade support frame forms a three dimensional structure by the bounce of the spring to support the veil to a three-dimensional lampshade. When the lampshade is folded and compressed, the lampshade is compressed into plane or close to plane state by the upper and the lower support loop and the compression spring and folded for packing.

Description

A kind of spring folding lampshade

Technical field

The utility model relates to a kind of lampshade, particularly relates to a kind of spring folding lampshade.

Background technology

Existing lampshade mainly is made up of lampshade face shield and Lamp shade holder that the cloth material is made, and the lampshade face shield is fixedlyed connected moulding with Lamp shade holder, forms the three-dimensional shape of upper and lower opening, and is generally not collapsible.Its weak point is that the volume of lampshade is bigger, wires up to use material more, and it is bigger to take up room, and cost of transportation is higher.In order to overcome above-mentioned shortcoming, folding lampshade has appearred, and Chinese utility model patent ZL98210525.8 discloses a kind of spring folding lampshade, and this lampshade is by the spring of compression, bracing ring and soft lampshade decorative cover are formed up and down.Spring connects bracing ring up and down.Its weak point is that (1) whole bulb is enclosed within the interior space of spring, and the distance of spring and bulb is too near, can influence the use of bulb; (2) adopt the identical spring of bore up and down, make the Lamp shade holder structure complicated; In addition, be subjected to the influence of spring self thickness, lampshade can't be compressed into the plane or near the state on plane, compression degree is limited.

The utility model content

The purpose of this utility model provides a kind of simple in structure, folding convenient, is convenient to the collapsible cloth lampshade of spring of packed and transported.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of spring folding lampshade, comprise lampshade face shield and Lamp shade holder that flexible material is made, it is characterized in that: Lamp shade holder is by bracing ring and spring are formed up and down, has the structure that is connected with lamp body at least one bracing ring, described spring is the compression helical spring that outline and lampshade face shield stereo profile match, on the spring, following two ends are respectively with last, the lower support circle connects, spring bore up and down is big or small consistent with the upper and lower side bore of lampshade face shield respectively, on the face shield, lower port is fixed on the bracing ring of top and bottom of spring, Lamp shade holder forms D structure by spring force, and supporting face shield becomes three-dimensional lampshade.In the time will folding lampshade, the compression lampshade, face shield is along with bracing ring and compression spring are compressed into the plane or are folding so that carry out little packing near flat state up and down.

Compression helical spring described in the utility model and upper and lower bracing ring are connected as a single entity, and promptly the upper end of spring surrounds the upper support circle, and the lower end of spring surrounds the lower support circle.

Compression helical spring described in the utility model can adopt the circular cone Spring capable of diameter varying, and the upper support loop diameter is less than the lower support circle, with the three-dimensional lampshade of the hood-shaped one-tenth round platform of supporting surface formula.

Compression helical spring described in the utility model is the middle concave Spring capable of diameter varying, and the diameter of spring interlude reduces gradually to the centre, with the umbilicate dolioform three-dimensional lampshade of the hood-shaped one-tenth of supporting surface.

Compression helical spring described in the utility model is a cylindrical compression spring, and the bracing ring diameter is identical up and down, with the three-dimensional lampshade of the hood-shaped one-tenth straight barrel type of supporting surface.

Compression helical spring described in the utility model be lift angle＞? helical spring, on the one hand help improving its compression degree and reduce compression stress, also can save material on the other hand, reduce cost.

Upper support coil structures described in the utility model is that a circle centre position is provided with the annulus strong point that is connected with lamp body, outwards is provided with several spoke bars by this strong point and connects outer ring, the upper shed plane that is used to open the lampshade cover; The lower support circle is the circular metal circle of an annular, is used to strut the under shed of lampshade cover and makes its setting.

The beneficial effects of the utility model are: (1) Lamp shade holder adopts outline to do the design that skeleton directly is connected upper and lower bracing ring with the compression spring that lampshade face shield stereo profile matches, the compression that not only can realize lampshade is folding, and can also realize the variation of lampshade three-dimensional shape with simple structure; (2) owing to the spring that lampshade adopted is that great-lift angle compression spring is made skeleton, can be after folding to be flat, smaller volume is saved the space, reduces packaging material, is convenient to pack and transportation; (3) simple in structure, easy for installation, easily folding, the convenient purchase at home carried.
