Sliding block mechanisms and variable-pitch louver sliding block system with same

Abstract

The invention discloses sliding block mechanisms which are respectively used on a thrice quartered variable-pitch louver and a double dichotomy variable-pitch louver and a variable-pitch louver sliding block system with one of the two sliding block mechanisms. The variable-pitch louver sliding block system comprises gear torsion spring clutch turnover mechanisms, a base and a top cover, wherein the sliding block mechanisms are tightly adjacent to the gear torsion spring clutch turnover mechanisms, the sliding block mechanisms and the gear torsion spring clutch turnover mechanisms are all arranged on a rotating shaft of the sliding block mechanisms, each gear torsion spring clutch turnover mechanism comprises a fixing sleeve, a torsion spring, a torsion spring unlocking gear, a clutch gear and a fixing nut which are sequentially sleeved on the rotating shaft, and the torsion spring unlocking gears are connected with the sliding block mechanisms through a clamping part in a transmission way. According to the sliding block mechanisms and the variable-pitch louver sliding block system, which are disclosed by the invention, an existing sliding block mechanism and an existing variable-pitch louver sliding block system are improved, the problems that a torque transmission piece is not synchronous with a turnover drum, and ladder belts are easily abraded are effectively solved, and the sliding mechanisms are also suitable for the double dichotomy variable-pitch louver.

Description

technical field [0001] The invention relates to a shutter accessory and a shutter working system equipped with the accessory, in particular to a slider mechanism and a variable-pitch shutter slider system with the slider mechanism. Background technique [0002] A fatal flaw of traditional blinds is that the indoor daylight illumination cannot be uniform. If the louvers are turned over to make the light near the windows moderate without glare, then the illuminance in the depth of the room is not enough, and artificial lighting is needed; if the louvers are turned up to make the light in the depths of the room moderate, glare will be generated near the windows. In addition, in summer, people only need moderate light but not heat, and in winter, people need both moderate light and heat. In order to reduce the light and heat near the window, traditional blinds must be closed no matter in summer or winter. The louver blades are flipped to the degree that they are almost closed, ...

Problems solved by technology

[0003]In order to overcome the asynchrony between the torque transmission part and the turning cylinder of the power transmission gear torsion spring clutch turning mechanism in the existing variable pitch shutter slider system, and the slider mechanism The unreasonable way of connecting wires with the ladder belt will easily cause the defect of ladder belt wear. The present invention provides an improved slider mechanism and a variable pitch blinds slider system with the slider mechanism. The torque transmission part and the turning cylinder Integrate into one and remove half of the surface of the turning cylinder, and remove the slide bar connecting the two, which can effectively ensure the synchronous rotation of the turning cylinder and the torque transmission part, and reduce the wear of the ladder belt. A guiding and positioning structure is also introduced between the second slider and the third slider, so that the slider no longer produces eccentricity and cannot return to the initial position. The threaded section of the shaft is improved and the second slider is introduced. The variable-pitch blinds slider system adopting the slider mechanism realizes the possibility of double dichotomous variable-pitch adjustment
