Abstract

The utility model discloses an automatic rolling screen curtain which is arranged at a sliding window, wherein, one end of the screen curtain is fixed in the direction of the length of a winding up roller, and both ends of the winding up roller are fixed and supported by brackets. At least one bracket is provided with a spiral spring which drives the winding up roller to rotate around the central axis of the fulcrum, and can make the screen curtain wound around the winding up roller. The other end of the screen curtain is connected with a pull rod. When the pull rod moves along the window plane, the screen curtain is pulled and deployed smoothly, so as to realize the goal of ventilation and prevent flies and mosquitoes from coming indoors. The utility model has simple and reliable structure, convenient installation and operation.

Description

Plug-type from rolling up the yarn curtain

The utility model relates to a kind of yarn of volume certainly curtain by clockwork spring driving winding up roller that is installed on the sliding window.

The accessories for windows and doors of screen window or title yarn curtain is used for ventilating and blocking mosquitos and flies by people at large, existing screen door window normally is fixed on gauze on the wooden frame, member with hinge one class links to each other with window frame again, along with improving constantly of human living standard, the aluminum alloy push-pull window is popularized day by day and on the aluminum alloy push-pull door and window yarn curtain is installed then is a difficult problem.

The purpose of this utility model is to design a kind of push-and-pull extended flat, rolls up reliable yarn curtain certainly.

For achieving the above object, the technical solution adopted in the utility model is: plug-type from rolling up the yarn curtain, the length direction of one end edge winding up roller of yarn curtain is fixed, the two ends of winding up roller are by the support fixed bearing, at least one end support is provided with clockwork spring and drives winding up roller and rotates and the yarn curtain can be wrapped on the winding up roller around its fulcrum central axis, the other end limit of yarn curtain links to each other with pull bar, and pull bar is torn expansion with the yarn curtain is smooth when move on the forms plane.

In the utility model, the winding up roller that twines the yarn curtain is fixed on the window frame together with bearing support under normal conditions, the window frame that pull bar is movably being inlayed glass during then with push-and-pull links to each other, the latter then adopts dismountable movable connection form, and the smooth expansion of yarn curtain realizes the needs of ventilation, the open air that mosquitos and flies can be refused again thus, when window frame moves when closing, the elastic force of clockwork spring drives winding up roller and rotates and the yarn curtain is furled certainly, and the utility model is simple in structure, and is easy to install.

Embodiment

Referring to Fig. 1, the length direction of one end edge winding up roller (10) of yarn curtain (14) is fixed, the two ends of winding up roller (10) are by the support fixed bearing, clockwork spring (20) drive winding up roller (10) set on the support rotates and yarn curtain (14) can be wrapped on the winding up roller (10) around its fulcrum central axis, the other end limit of yarn curtain (14) links to each other with pull bar (40), pull bar (40) is torn expansion with yarn curtain (14) is smooth when move on the forms plane, simultaneously referring to Fig. 2, in support comprises, outward, middle support plate (30), (31), (32), wherein, outer support plate (30), (31) be provided with driving shaft (21) between, outside driving shaft (21) is positioned at, middle support plate (31), (32) on the axle between clockwork spring (20) is set, driving shaft (21) is positioned at, middle support plate (30), (32) on the axle between driving gear (22) is set, this gear (22) is gone up set driven gear (12) engagement with driven shaft (11), driven shaft (11) links to each other with the end of winding up roller (10), when clockwork spring (20) drives driving shaft (21) and driving gear (22) when together rotating under himself elastic force effect, rotate driving with the driven gear (12) of its engagement and driving winding up roller (10), and yarn curtain (14) is wrapped on the winding up roller (10).Above-mentioned clockwork spring (20) can select for use with alarm clock on walk bar or the similar clockwork spring of noisy bar, its installation should be reliably firm, the gear ratio of the gear of driving and driven gear is 2: 1, can reduce the length of clockwork spring (20) like this, increases the stability of clockwork spring moment.

As seen, the lower end of winding up roller (10) is a simple supporting form in the structural representation of the lower left quarter among Fig. 1, and it also can be by the structure support shown in its upper end, and corresponding clockwork spring (20) and the gear pair of adding in fact.

Referring to Fig. 3, Fig. 4, winding up roller (10) is by two

The rod member of type closes by the emperor himself mutually and constitutes, and yarn curtain (14) is fixed on the joint place of the two, and the termination of winding up roller (10) is provided with contiguous block (13), and an end of described driven shaft (11) is arranged in contiguous block (13) axial holes of opening (13a), simultaneously with reference to figure 2.

In Fig. 2, inside and outside, middle support plate (30), (31), (32) are fixedly connected by pin (33), in, the pin (33) between middle support plate (30), (32) and domestic and abroad support plate (32), (31) is provided with lining (34), this scheme has good processability of product structure.

As seen from Figure 1, comprise inside and outside, middle support plate (30), (31), (32), clockwork spring (20), winding up roller (10) place in the housing (50), and housing (50) is that the cross section is The section bar of shape, its two ends have cover (51) capping, the gap that can supply yarn curtain (14) freely to contract and stretch is arranged between this housing (50) and the forms, in the time of in yarn curtain (14) is involved in housing (50), pull bar (40) is positioned at the side of housing (50), simultaneously referring to Fig. 5, Fig. 6, pull bar (4 0) is to be by two cross sections
