Abstract

The utility model discloses a rolling shutter head structure suitable for different sizes, which comprises a rolling shutter head main body, wherein an inner head cover is arranged on the rolling shutter head main body, an outer head cover is sleeved on the inner head cover, the diameter of the outer head cover is larger than that of the inner head cover, and the outer head cover is sleeved on the inner head cover.

Description

Be suitable for different size's roller shutter system head structure

Technical Field

The utility model relates to the technical field of hardware mounting accessories, in particular to a roller shutter head manufacturing structure applicable to different sizes.

Background

The rolling curtain is one of window decoration products and mainly comprises rolling pipes, fabric, a head, a bead curtain pull rope, a mounting bracket and other accessories. The existing roller shutter head is usually assembled by inserting the head into the end of the roller tube, so that the ribs on the outer side of the head cover of the head are matched with the roller tube, and the aim of simultaneously rotating the head and the roller tube is fulfilled. However, the existing roller shutter head cover can only be matched with the roller pipes with the same pipe diameter, and when the roller pipes with larger or smaller sizes are required in the installation environment, the whole roller shutter head needs to be replaced, so that the installation cost is increased.

Disclosure of Invention

The present utility model is directed to a roller shutter head structure suitable for different sizes, and solves the above-mentioned problems in the prior art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a be suitable for not unidimensional roller shutter system head structure, includes roller shutter system head main part, install interior system skull in the roller shutter system head main part, the cover is established on the interior system skull and is installed outer system skull, the diameter of outer system skull is greater than the diameter of interior system skull.

Preferably, the outer wall surface of the inner head cover is provided with a plurality of raised lines along the circle center, and a positioning groove is formed between the adjacent raised lines, the inner wall surface of the outer head cover is at least provided with 2 positioning strips, and the positioning strips are matched with the positioning groove.

Preferably, the number of the positioning grooves is 18, and the number of the positioning strips is 8.

Preferably, the outer wall surface of the outer head cover is distributed with convex ribs for connecting the roller shutter sleeve.

Compared with the prior art, the utility model has the beneficial effects that: by adopting the outer head cover with the diameter larger than that of the inner head cover and sleeving and installing the outer head cover on the inner head cover, the structure can be suitable for various large-size rolling pipes by replacing the outer head cover without replacing the whole rolling shutter head.

Fig. 3 is a schematic view of another angle of the present utility model.

In the figure: the roller shutter head comprises a roller shutter head main body 1, an inner head cover 2, a convex strip 21, a positioning groove 22, an outer head cover 3, a positioning strip 31 and a convex rib 32.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a roller shutter head structure suitable for different sizes, comprising a roller shutter head main body 1, an inner head cover 2 is installed on the roller shutter head main body 1, an outer head cover 3 is installed on the inner head cover 2 in a sleeved mode, and the diameter of the outer head cover 3 is larger than that of the inner head cover 2.

As a preferred embodiment of the present utility model, the outer wall surface of the inner head cover 2 is provided with a plurality of protruding strips 21 along the center of the circle, and positioning grooves 22 are formed between adjacent protruding strips 21, the inner wall surface of the outer head cover 3 is provided with at least 2 positioning strips 31, and the positioning strips 31 are adapted to the positioning grooves 22.

As a preferred embodiment of the present utility model, there are 18 positioning grooves 22, and 8 positioning bars 31.

As a preferred embodiment of the present utility model, the outer wall surface of the outer cover 3 is provided with ribs 32 for connecting the roller shutter sleeve.

By adopting the outer head cover 3 with the diameter larger than that of the inner head cover 2 and sleeving and installing the outer head cover 3 on the inner head cover 2, the structure can be suitable for various large-size rolling tubes by replacing the outer head cover 3 without replacing the whole rolling shutter head.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the utility model as defined by the appended claims and their equivalents.
