Overturning pulling rope automatic tensioning bottom inserting corner structure used in built-in shutter hollow glass

Abstract

The invention discloses an overturning pulling rope automatic tensioning bottom inserting corner structure used in built-in shutter hollow glass. The structure comprises an inserting corner connecting base which is composed of a longitudinal inserting head and a transverse inserting head, a curtain piece overturning traction rope floating tensioning mechanism and a sliding frame adjusting mechanism, wherein the curtain piece overturning traction rope floating tensioning mechanism comprises a sliding frame and a curtain piece overturning traction rope transition wheel, the sliding frame adjusting mechanism comprises a sliding guide column, a side guide sliding plate, a tensioning spring, a spring force adjusting limiting piece and a tensioning force adjusting bolt. According to the overturning pulling rope automatic tensioning bottom inserting corner structure used in built-in shutter hollow glass, the top of the sliding frame is provided with a pair of transition wheel supporting seats, the curtain piece overturning traction rope transition wheel is arranged between the opposite sides of the pair of transition wheel supporting seats, the sliding frame forms a sliding frame cavity, the spring force adjusting limiting piece and the tensioning spring are arranged in the sliding frame cavity, the tensioning force adjusting bolt stretches into the sliding frame cavity to be connected with the spring force adjusting limiting piece, the left side of the sliding frame is matched with the right side of the longitudinal inserting head, the middle part of the sliding frame is matched with the sliding guide column, and the right side of the sliding frame is matched with the left side of the side guide sliding plate; the up-down floating stability of the sliding frame serving as a moving part can be guaranteed; the tensioning effect is guaranteed; and the applicability is good.

Description

technical field [0001] The invention belongs to the technical field of sun-shading hollow glass products, and in particular relates to a flipping traction rope automatic tensioning bottom inserting angle structure for internal use of built-in louver hollow glass. Background technique [0002] The aforesaid built-in louver hollow glass is actually a built-in louver for hollow glass. The built-in shutters of insulating glass have the following self-evident advantages: good heat insulation can reflect the energy saving of the building; excellent sound insulation performance can avoid the disturbance of external noise; Expected bright effect; through the adjustment of the deflection angle of the blinds, the required indoor lighting requirements can be obtained and the privacy can be protected; the venetian blinds (customarily referred to as "curtains") can be reflected excellently No-cleaning effect; ideal embellishment for buildings to improve the grade of buildings; strong im...

Problems solved by technology

[0006]Generally speaking, the position of the inner and outer manipulators on the side of the window cannot be selected arbitrarily, otherwise it will affect the reasonable tension of the curtain flipping traction rope Therefore, in the actual use process, for different users, due to the difference in human body height, if the position of the inner and outer control mechanisms is selected at a position far from the lower edge of the window, then there is an operation problem for the shorter person. It is difficult or even difficult to touch the external controller

In addition, because the two ends of the curtain flipping traction rope need to be connected with the inner manipulator by manual knotting, there will inevitably be a slack margin after knotting, so that the curtain flipping traction rope The length between the two knotting points more or less exceeds the actual length required by the process, which eventually leads to a decrease in the tensioning effect of the curtain flipping traction rope

On the other hand, after a period of use, the flipping traction rope of the curtain will also produce a slight elongation phenomenon, which will also affect the turning effect of the curtain

[0007] Chinese patent authorization announcement number CN209523684U recommended "insulating glass built-in louver curtain flip traction rope tensioning device" can make up for the aforementioned shortcomings and can be objectively reflected in its The technical effects recorded in the technical effect column of the manual, but still have the following shortcomings: one, due to the tension spring of the structural system of the sliding frame adjustment mechanism and the curtain flipping traction rope of the structural system of the curtain flipping traction rope tensioning device The transition wheel is in the positional relationship set left and right, so it is not enough to make the two form the desired longitudinal concentricity relationship, which eventually leads to the unsatisfactory stability of the moving parts; The state is set on the sliding frame, so on the one hand, it will affect the tension effect to a certain extent; The friction on both sides of the crossbeam) will easily cause the curtain flipping traction rope to break after a long time, and on the other hand, it will affect the smooth operation of the inner and outer controllers
