Abstract

The utility model relates to a rail structure for a bead rolling curtain type screen window, comprising a window screen rack, a base and a connector pin. Wherein, an upright rod for the edge of the window screen penetrating is arranged at the inner side of the rack which is in the strip shape; wool strip grooves are respectively arranged at the left side (right side) and the inner side for wool strips being embedded in, playing the sealing function between the window frame and the wall face. The base is provided with at the lower end of the rack, playing head sealing and fixing functions on the upright rod. The utility model has reasonable structure and favorable sealing performance, preventing mosquito from entering into living rooms from slits, and meanwhile, the window screen moves up and down flexibly and conveniently.

Description

The track structure of drawing roll bead curtain type screen window

Technical field

The utility model belongs to the interior decoration technical field, is specifically related to a kind of track structure of drawing roll bead curtain type screen window.

Background technology

In order to prevent mosquito rope invasion and attack room in summer and autumn, people often will install screen window on door and window.Traditional screen window mostly is a unscrewing type or plug-type.Unscrewing type screen window and common door-window kind coloured silk and hinge arrangement rotarily open.Plug-type screen window is at former window mobile chute to be installed up and down, and screen window and door push-and-pull in chute is opened this screen window and often assembled dust stratification dirt, and easy cleaning is not deposited inconvenience winter.In recent years, a kind of spring rolling curtain type screen window has been released in market, and this screen window can be left behind window screening in use; When not using, under the effect of spring, window screening can up be rolled, and can reduce dirt accumulation, also has the problem of collecting winter.But this screen window spring is loose easily, and corrosion takes place easily, makes to open inconvenience.Along with people's growth in the living standard of standing, the improvement of room condition, people require also constantly development to decorateing.A kind of drawing roll bead curtain type screen window arises at the historic moment.This screen window is constituted by track (framework), case, window screening, bead, pulley, spool etc.Its structure as shown in Figure 1.During use, the pulling bead drives pulley and rotates, thereby volume is rotated, and screen window is rolled thereupon and put down.When not using, window screening is rolled by spool and is concealed in the case.This screen window good looking appearance, easy to use, be subjected to people's welcome.But the track of this screen window (being side frame) structure is reasonable inadequately, and sealing property is relatively poor, and mosquito is swarmed into the room from the track slit easily.

Summary of the invention

The purpose of this utility model is to design a kind of rational in infrastructure, the track structure of the drawing roll bead curtain type screen window of good seal performance.

The track structure of the drawing roll bead curtain type screen window of the utility model design is made of its structure such as Fig. 2, Fig. 3 and shown in Figure 4 window screening track, base, vertical rod and latch.Wherein, window screening track (that is frame of screen window) 5 is an elongate in shape, its cross section as shown in Figure 2, its right side is the structure of square frame band semi arch, middle opening 7 for penetrating for window screening 4, the side of window screening 4 is through on the vertical rod 11, and vertical rod 11 places in the square frame of right side, and the left side of track is the structure of square frame 8.

In the track structure of the utility model design, the left side of its track 5 and inboard (being a frame near the window and a side of leaning on wall) also can be respectively equipped with wool top groove 9 and 10.After groove is embedded in felt class wool top, play and window frame and metope between further sealing function, can avoid mosquito to swarm into the room from the slit.

Window screening track among above-mentioned Fig. 2 is the track in left side.If the track on right side sees that the direction of figure is opposite.

In this track structure, base 12 is installed on the bottom of track, mates with the track cross-sectional profile.Its structure as shown in Figure 3.The upper side of base 12 is respectively equipped with

square frame projection

13 and 14, for its bottom of inserting track 6, is provided with pin member 15 in the square frame projection 14 of base, and its structure as shown in Figure 4.These latch 15 front ends are provided with a cylindricality projection 16, are circular hole 17 in the projection 16, insert for the lower end of the vertical rod 11 in the track, and are in the centre bore of the square frame projection 14 of latch 15 embedding bases 12, fixing.

The screen door track of the utility model design, rational in infrastructure, window screening interiorly move up and down flexibly, convenient, and have better with window frame and metope and to be sealed and matched, can thoroughly stop mosquito and enter the room from the slit.
