In order to ensure the air tightness of the whole product, the curtain is generally operated by magnetic force. However, when the size is large, the weight of the curtain vanes and the friction between the vanes and the glass make the curtain difficult to operate only by magnetic force. Therefore, it is common practice to add a weight to the built-in magnetic handle to reduce the required operating force, but since the operating force required by the window covering during the raising process is increased, the weight of the weight cannot be changed, and only part of the weight of the window covering vanes can be balanced. Also, when assembled and transported, the unsecured counterweight can move freely and damage adjacent fittings.
Moreover, when the curtain component of the hollow built-in shutter is stored or transported, the blades are folded to avoid the damage of the blades, and at the moment, if the lower beam, the blade component and the upper beam are assembled and then assembled with the side frame to form an L-shaped unstable structure, the storage or the transportation occupies a large space and is easy to damage; if the lower beams, the blade assemblies and the upper beams are assembled and stored or transported independently without being assembled with the side frames, much space can be saved, but the blade assemblies are easy to scatter, so that the blades are bent and deformed. The existing solution is that the lower beam, the blade assembly and the upper beam are assembled and then the blades are folded, and then the blades are bound and stored or transported, and the binding is removed when the whole curtain assembly is assembled with hollow glass, so that the time and labor are wasted.

This allows easy control of the lifting and turning of the blade assembly 15 with a small force, and also allows a large-sized hollow built-in blind to be implemented.
As shown in fig. 8 and 9, when transporting a counterweight type hollow built-in blind window with self-locking capability, the blind window is generally in a lateral lying state, the side frame 13 is in a horizontal position, the gravity of the counterweight 8 cannot generate a pulling force on the base 71 of the counterweight self-locking device 7, the elastic sheet 73 in the base 71 is not jacked up by the elastic sheet jacking block 72b on the cover plate 72, at this time, the elastic sheet 73 is in a flat state, the free end of the elastic sheet 73 extends out of the vertical edge of the base 71 and is in close contact with the inner surface of the side frame 13 to form self-locking, and the counterweight 8 cannot move towards the counterweight self-locking device 7; the weight 8 cannot move in the opposite direction because of the tension of the weight line 66. Therefore, the counterweight 8 can not impact and damage other parts due to movement. In a similar way, the side frame 13, the gear box 6 and the built-in magnetic handle 9 in the side frame, the balancing weight self-locking device 7, the balancing weight 8, the belt tensioning wheel 11 and the belt can be stored or transported independently after being assembled, and the balancing weight 8 cannot damage products due to free movement.
As shown in fig. 2, 3 and 4, when the upper beam 3 is not assembled with the side frame 13, the fixing seat 51 is fixed in the upper beam 3, the gear box 6 in the side frame 13 is not connected with the rotating rod locking device 5, after the locking ring 53 is pushed out of the fixing seat 51 by the spring 54 for a certain distance, the locking ring 53 still remains partially in the fixing seat 51 and cannot rotate, the internal gear of the locking ring 53 is engaged with the external gear part on the gear shaft 52, the gear shaft 52 is locked and cannot rotate freely, and the rotating rod assembly 4 fixed together with the gear shaft is also unable to rotate freely. Thus, the tightened blade assembly 15 will not be scattered, and the assembled lower beam, blade assembly and upper beam can be stored or transported separately from the side frames, thereby saving space and protecting the blades.
