Technical Field

The invention belongs to the technical field of sun-shading hollow glass products, and particularly relates to an automatic tensioning bottom inserting angle structure of a turnover traction rope used in built-in shutter hollow glass.

Background

The hollow glass with built-in shutter is substantially a hollow glass built-in shutter. The hollow glass built-in shutter has the following advantages: the heat insulation performance is good, so that the energy conservation of the building can be embodied; excellent sound insulation performance to avoid the disturbance of external noise; the condensation and frost prevention can ensure sufficient indoor light and show expected bright effect; the required indoor lighting requirement is obtained and the privacy is protected by adjusting the deflection angle of the curtain sheet of the blind; the shutter curtain sheet (the habit is called as the 'curtain sheet' for short) is prevented from being polluted by dust, so that the excellent cleaning-free effect is embodied; the decorative board has ideal decorative property for buildings so as to improve the grade of the buildings; the high-rise building has strong impact resistance, good safety and long service life, so that the installation requirement of a high-rise building can be met, and the extremely long-term use maintenance-free requirement can be met; the operation is simple, light and labor-saving, and can be suitable for people of different ages and physical abilities, and the like.

Technical information on the hollow glass with built-in blinds, that is, the hollow glass built-in blind described above, is not known in the published chinese patent documents, such as CN2564720Y (hollow glass with built-in blinds), CN2767624Y (blind in hollow glass), CN2767625Y (blind in hollow glass with improved structure), CN2756796Y (blind in hollow glass), CN2232968Y (integral door and window sash with transverse blind in double glass), CN2297952Y (magnetically driven laminated retractable curtain), CN2326718Y (fully enclosed blind), CN100535378C (blind in hollow glass with improved structure), CN102444372A (a built-in sun-shading hollow blind), CN105064896B (single-control double-glazing built-in blind), CN105041168B (energy-saving multilayer hollow glass blind with simplified structure), CN105041170B (non-magnet double-drive double-glazing built-in blind), CN105041172B (bead chain drive double-glazing built-in blind), CN109538096A (double-control hollow glass built-in shutter with shutter cavity balanced with external pressure), CN109538097A (shutter anti-slipping device for hollow glass built-in shutter), CN109441323A (single-control hollow glass built-in shutter capable of preventing shutter from slipping down), CN109488189A (single-control hollow glass built-in shutter capable of preventing absorption in glass), and so on.

It will no doubt be determined by a reading of the patent literature that is not limited to the above list and in combination with general knowledge: the blind arranged in the double-layer hollow glass must meet the requirements of lifting according to requirements and turning over the blind sheets. The process of the curtain piece overturning is as follows: because the outer manipulator, that is, the outer control mechanism, is magnetically attracted with the inner manipulator, that is, the inner control mechanism, which is located between the front glass (the glass facing the room in the use state) and the front glass and the rear glass (the inner glass and the outer glass, the same applies hereinafter) and is in sliding fit with the longitudinal frame cavity of the longitudinal frame of the inner frame, when a user stirs the outer manipulator, the outer manipulator drives the inner manipulator, the inner manipulator drives the curtain sheet turnover traction rope, the curtain sheet turnover traction rope drives the turnover wheel, the turnover wheel drives the curtain sheet turnover shaft inserted and fixed with the turnover wheel, the curtain sheet turnover shaft drives the turnover roller (also called turnover drum) inserted and fixed with the turnover roller and rotatably supported at the two ends on the turnover roller seat (also called turnover drum seat "), the turnover roller seat and the turnover roller are arranged on the upper transverse frame strip of the inner frame, and the upper end of the ladder rope of the blind is fixed with the turnover roller, thus, when the curtain sheet turning shaft rotates clockwise or anticlockwise by a required angle, the turning roller (namely the turning drum) is driven by the curtain sheet turning shaft to rotate correspondingly by the required angle, so that the curtain sheet is turned inwards or outwards by the required angle through the ladder rope by the turning roller. As for the lifting of the blind, the lifting is realized by driving the inner manipulator to move through the operation of the outer manipulator, specifically, the inner manipulator drives the retractable rope of the blind lifting traction rope, one end of which is connected with the bottom strip of the blind, the middle part of which is sleeved on the rope sleeving wheel at the upper part of the inner manipulator, and the other end of which is fixed on the window body corner seat. For example, the outer manipulator drives the inner manipulator to move downwards, then the blind lifting traction rope is retracted, and the blind is lifted upwards, and vice versa.

The known connection mode of the curtain turning traction rope is as follows: the two ends of the curtain turning traction rope are fixed with the side part of the inner manipulator in a manual knotting mode, namely, the inner manipulator is connected in series on the curtain turning traction rope, the middle part of the curtain turning traction rope is sleeved on a curtain turning traction rope wheel and a curtain turning traction rope tension wheel (also called a curtain turning traction rope transition wheel, the same applies hereinafter), the curtain turning traction rope wheel is usually fixed on a turning shaft at a position corresponding to the upper part of the inner control mechanism, the curtain turning traction rope tension wheel is rotatably arranged on a bottom inserting angle connecting seat at the lower part of the window body at a position corresponding to the lower part of the inner manipulator, and the bottom inserting angle connecting seat has the function of connecting the end part of a lower transverse frame pipe of a structural system of the window body with the end part of a longitudinal frame pipe of the window body, for example, the lower end of a left longitudinal frame pipe and the left end of the lower transverse frame pipe are inserted and embedded. According to the professional knowledge, the window body comprises two transverse frame tubes, namely an upper transverse frame tube, a lower transverse frame tube and two longitudinal frame tubes, namely a left longitudinal frame tube and a right longitudinal frame tube, so that the number of the corner connecting seats is four, two of the corner connecting seats are top inserting angle connecting seats, and the other two of the corner connecting seats are bottom inserting angle connecting seats, so that the two transverse frame tubes and the two longitudinal frame tubes are connected into a square structure.

Generally speaking, the positions of the inner and outer control devices at the side of the window body cannot be selected at will, otherwise, the reasonable tensioning effect of the curtain sheet overturning traction rope can be influenced, so that in the actual use process, for different users, due to the difference of the heights of human bodies, if the positions of the inner and outer control mechanisms are selected to be far away from the lower edge of the window body, the operation is difficult for the short users, and even the short users can not touch the outer control device. In addition, because the two ends of the curtain sheet overturning hauling rope need to be connected with the inner controller in a manual knotting mode, the loosening allowance after knotting inevitably appears after knotting is finished, so that the length of the curtain sheet overturning hauling rope between two knotting points is more or less beyond the actual length required by the process, and finally the tensioning effect of the curtain sheet overturning hauling rope is reduced. On the other hand, after a period of use, the curtain turning traction cords also produce a subtle phenomenon of elongation which also affects the turning effect on the curtain.

The curtain turning and pulling rope tensioning device for the hollow glass built-in shutter recommended by the chinese patent publication No. CN209523684U can make up for the above-mentioned deficiencies and objectively embody the technical effects thereof recorded in the technical effect column of the specification, but still has the following disadvantages: firstly, because the tensioning spring of the structure system of the sliding frame adjusting mechanism and the curtain sheet overturning traction rope transition wheel of the structure system of the curtain sheet overturning traction rope tensioning device are in a left-right arranged position relationship, the two mechanisms are not in a desired longitudinal concentricity relationship, and finally the stability of a moving part is not ideal; secondly, because the curtain piece upset haulage rope ferryboat tends to the interior concealed state setting on the carriage, therefore can influence the effect that rises to a certain extent on the one hand, on the other hand has the both sides friction of curtain piece upset haulage rope and the entablature of carriage (corresponding to the crossbeam that the curtain piece upset haulage rope crossed the ferryboat top), and the time is for a long time and easily makes the curtain piece upset haulage rope fracture, can influence the smooth and easy operation effect of interior outer control ware on the other hand again.
