In the prior art, a full-circle gear is adopted, a sector gear with a central angle of 90 degrees is adopted in order to increase the stroke of a shifting fork, and in one embodiment, the panel shell 1 of the handle provided by the invention has the following geometric dimensions: the length is 110mm, the width is 42mm, the height is 20.5mm, and the stroke of the shifting fork can be as much as 31 mm. Compared with the prior handle, the length, the width and the height are 115, 35 and 20, and the stroke is only 20 mm. Therefore, the invention can clearly see that the stroke of the shifting fork is greatly increased on the premise of not obviously increasing the overall dimension of the panel shell.
This is not done in the prior art, since modifying the circular gear to a sector gear can have this effect.
The invention uses the sector gear, the rotation center of the gear is eccentric state for the gear part, thus, the handle is unstable and easy to damage in use. In order to solve the problem, the invention designs an elongated gear shaft, namely, a positioning circular truncated cone 33, a cylindrical section 34 and a rectangular conical square platform 35 are integrally formed behind a gear part 31 and a stop plate 32 of the sector gear 1.
The ratio of the axial length of the shaft sections as the cylindrical section 34 and the tapered square table 35 to the entire axial length of the gear is 0.5 to 0.7, and the ratio of the total axial length of the gear portion 31 and the stopper plate 32 to the entire axial length of the gear is 0.2 to 0.25; in addition, the positioning circular platform 33 is different from the handle structure in the prior art, the positioning circular platform, the gear part and the stop plate are separated in the prior handle, and the positioning circular platform is embedded in the grooves of the gear part and the stop plate, but the positioning circular platform, the gear part and the stop plate are made into a whole, and in addition, the ratio of the radius of the positioning circular platform 33 to the radius of the gear part 31 is 0.5-0.6. The ratio of the axial length of the conical square table 34 of the sector gear 3 to the entire axial length of the gear is 0.25-0.35; the taper of the tapered square platform 35 is 3-5 degrees.
In the embodiment shown in fig. 8c, the shaft section has a length of 16mm, wherein the cylindrical section 34 and the conical square platform 35 are both 8mm in length, and the overall axial length is 27.5 mm. The longer gear shaft is inserted in the grip 1, which can improve stability. The large positioning round table 33, which has a diameter of 24.3mm and a radius of 22.5mm in the gear portion 31, can also increase the stability of the sector gear.
In the curtain wall window handle in the prior art, the gear for driving the shifting fork is a full-circle gear, but the working range is 0-90 degrees, the quarter gear is used for replacing the full-circle gear, under the condition that the overall dimension of the panel shell 1 is not increased, the diameter of the quarter gear can be 2 times that of the existing full-circle gear, and the stroke of the shifting fork 4 can be increased in the working range of 0-90 degrees. In practical application, under the same size of the panel shell, the stroke of the handle in the prior art is 20mm, and the stroke of the handle with the quarter-gear provided by the invention can be increased to 31.4 mm.
The stroke of handle has been increased, can also adapt to the bigger error of peripheral parts such as curtain window, in the operation in the big fan that opens, can switch the curtain window smoothly.
The shape of the longer pole section of grab handle 2 is as shown in fig. 4a, and for the rectangular cross section body of rod that a four corners is the fillet, two apex angles size on one side inwards promptly towards panel casing 1 one side equals, and two apex angles size on one side outwards also equals, but the fillet radius of apex angle inwards is greater than one side apex angle radius outwards. The appearance size of the grab handle 2 meets the requirement of human engineering, and the applicability is strong; in a particular embodiment, the apex angle of the inwardly facing side has a radius of 8mm and the apex angle of the outwardly facing side has a radius of 3 mm. In this embodiment, the handle 2 is integrally formed by die casting zinc alloy, and the forming appearance of the handle is good due to the material and the forming mode. The surface of the zinc alloy grab handle can be sprayed with fluorocarbon, and the effects of spraying color, pattern and the like can be adjusted according to the requirements of customers, so that the applicability is enhanced.
The sector gear and the shifting fork with the rack are made of die-cast zinc alloy with the brand number ZZnA14Cu1Y, and the tensile strength of the material is greater than or equal to 270 Mpa. The material has high strength and strong durability.
The panel shell 1 of the handle is integrally formed by die casting of the zinc alloy, and the forming appearance effect is good. The surface of the zinc alloy grab handle can be sprayed with fluorocarbon, and the effects of spraying color, pattern and the like can be adjusted according to the requirements of customers, so that the applicability is strong.
Through detection, the transmission performance and the use hand feeling of the quarter-gear handle are not different from those of a full-circle gear handle, and the balance problem is avoided.
It should be noted that: the handle of the quarter-circle gear determines the direction of rotation of the gear (clockwise or counterclockwise). Two quarter circle gears with different rotation directions cannot be used universally and need to be adjusted to be consistent in direction. The transmission of the full-circle gear can be divided into left and right, namely the working range can be 0-90 degrees or-90-0 degrees, only a quarter circle is used in practical use, the stroke of the full-circle gear handle with the same radius is the same as that of the quarter-circle gear handle, and the whole size of the quarter-circle gear is only half of that of the full-circle gear.
Two quarter circle gears with different rotation directions cannot be used universally and need to be adjusted to be consistent in direction. The adjusting method is to disassemble the fastening screw of the gear, then adjust the direction of the gear, and finally fix the gear again. Adjusting the gear direction requires only flipping the gear over (from fig. 5 to the direction of fig. 12).
In order to prevent the gear from loosening, an anti-loosening structure can be additionally arranged on the fastening screw.
