Description

Lifting and curtain piece overturning device for single-side control of built-in blind curtain of hollow glass

Technical Field

The utility model belongs to the technical field of sun-shading hollow glass products, and particularly relates to a lifting and curtain sheet overturning device for a unilaterally controlled hollow glass built-in blind.

Background

As known in the art, the hollow glass built-in blind is a built-in hollow glass window. The hollow glass window with the 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 a hollow glass built-in blind, that is, the aforementioned built-in blind hollow glass window, is not known in the published chinese patent documents, such as CN2564720Y (hollow glass with built-in blind), 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 a lateral 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-layer hollow glass built-in blind), CN105041168B (energy-saving multilayer hollow glass blind with simplified structure), CN105041170B (non-magnet driven double-layer hollow glass built-in blind), CN105041172B (bead chain double-layer hollow glass built-in blind), and others, 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, namely between the inner glass and the outer 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 is magnetically attracted with the inner manipulator through the inner glass (the glass facing the indoor in the use state), when a user dials the outer manipulator, the outer manipulator drives the inner manipulator, the inner manipulator drives the curtain sheet overturning traction rope, the curtain sheet overturning traction rope drives the overturning wheel, the overturning wheel drives the curtain sheet overturning shaft fixedly inserted with the overturning wheel, the curtain sheet overturning shaft drives the overturning roller (also called 'overturning drum') fixedly inserted with the overturning roller and two ends of which are rotatably supported on the overturning roller seat (also called 'overturning drum seat'), because the turnover roller seat and the turnover roller are arranged on the upper cross frame strip of the inner frame body 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. Correspondingly, the lifting of the blind is realized by the rope retracting and releasing action of the lifting and pulling rope of the blind, that is, the outer controller drives the inner controller to move downwards, the inner controller drives the lifting and pulling rope of the blind to retract, and the blind is lifted upwards, or vice versa, and the above-mentioned patent documents are specifically referred to, and thus the description is omitted.

Then, it is also known from reading the above-mentioned patent documents that: the hollow glass built-in blind, i.e. the built-in blind hollow glass window, is divided into two-sided operation and one-sided operation, the so-called two-sided operation is to arrange a blind turning operation mechanism (blind turning inner and outer manipulators) on one side of the window body, e.g. on the left side of the window body, and to arrange a blind lifting operation mechanism (blind lifting inner and outer manipulators) on the other side of the window body, e.g. on the right side of the window body, for a typical example, see CN104912469B (double-layer hollow glass built-in blind); the so-called single-side operation is to arrange the blind slat turnover operation mechanism (blind slat turnover inner and outer manipulators) and the blind lifting operation mechanism (blind lifting inner and outer manipulators) on one side of the window (or on the left and right sides of the window, respectively) and the typical examples thereof are CN105064896B (single-control double-layer hollow glass built-in shutter) and CN108678637A (single-control double-layer hollow glass built-in shutter), etc. In general terms, a double-sided handle has two inner and two outer handles and the window requires one track (conventionally called "inner frame strip") on each of the left and right for the inner handle to slide; the single-sided operation has one or two inner manipulators and one or two outer manipulators and the window only needs one (i.e. one) rail for sliding one or two inner manipulators in up-and-down positional relationship. From the perspective of structural simplicity and economy, the single-side operation has certain advantages over the double-side operation, and is therefore well accepted by the industry and users.

From the above patents and in combination with the general knowledge in the art it is known that: the left end of an upper transverse frame tube of a structural system of the window body is connected with the upper end of a left longitudinal frame tube through a left upper corner connecting piece of the window body frame tube; the left end of the lower transverse frame pipe is connected with the lower end of the left longitudinal frame pipe through a left lower corner connecting piece of the window frame pipe; the right end of the upper transverse frame pipe is connected with the upper end of the right longitudinal frame pipe through a window frame pipe right upper corner connecting piece; the right end of the lower transverse frame pipe is connected with the lower end of the right longitudinal frame pipe through a window body frame pipe right lower corner connecting piece, so that the outer frame of the window body is formed into a square structure through four corner connecting pieces.

In a single-sided operating system, the inner operator is usually arranged in the right longitudinal frame groove of the right frame; matching the corner seat with the right upper corner connecting piece in an assembling mode; and the curtain sheet overturning and pulling rope tensioning mechanism is arranged on the lower right corner connecting piece of the window frame tube. This structure mainly exposes the following technical problems during the actual use: firstly, because the corner seat and the right upper corner connecting piece of the window frame pipe are in a split type assembling relationship, the manufacturing and assembling are troublesome, the cost is high, and the compact effect of the structure is influenced due to the loss of integrity; secondly, taking CN209523684U (blind turning traction rope tensioning device of hollow glass built-in shutter) as an example, since one side of the sliding frame of the structural system of the blind turning traction rope floating tensioning mechanism is in sliding fit with the longitudinal insertion arm of the insertion angle connecting seat, and the other side of the sliding frame is in sliding fit with the sliding frame guide post of the structural system of the sliding frame adjusting mechanism, and the adjusting screw penetrates the tensioning spring in the sliding guide post and is connected with the limiting member which is arranged on the upper part of the tensioning spring and is served as an external hexagon nut, it is difficult to avoid that the tensioning spring generates lateral deformation in the sliding guide post cavity of the sliding guide post, and especially the spring cannot generate the same balance acting force on the two sides of the sliding frame, so that the up-and-down sliding effect of the sliding frame is not enough to achieve the effect expected in the industry, that is, namely, the kinematic balance or smoothness of the sliding frame is poor; and thirdly, because the tensioning wheel (also known as the curtain sheet overturning traction rope transition wheel) of the curtain sheet overturning traction rope is sleeved and arranged on the sliding frame directly (pivoted) and moves up and down along with the sliding frame, and because the forces borne by the two sides of the sliding frame can not obtain the expected balance effect, the up-down unbalance of the tensioning wheel can directly influence the reasonable tensioning effect of the curtain sheet overturning traction rope, for example, the situation of neglecting looseness and looseness occurs, the smooth motion of an inner manipulator and an outer manipulator is influenced, and the curtain sheet overturning effect of the blind curtain is finally influenced. In view of the foregoing, there is a need for further improvement, and the solutions described below are made in this context.
