Embodiment Construction
[0011] exist figure 1 , figure 2 , image 3 Among them, the concealed hand crank machine includes a hand crank plate 14 and a gear reduction box 13. One side of the hand crank plate 14 is connected with a crank handle, and the other side is connected with a gear reducer box 13 through a cylindrical head cap screw 12. The output shaft of the gear reduction box 13 is connected with a sprocket 5, and the sprocket 5 cooperates with the chain 3. The front end of the chain 3 is connected with a fixed code 8, and the rear end of the chain 3 is connected with a chain tail limit block 4. Chain 3 is equipped with guide rail 7. The guide rail 7, the sprocket 5, the chain 3 and the chain tail limit block 4 are located in the chain case 11.
[0012] The output shaft of the gear reduction box 13 penetrates the sprocket 5, drives the sprocket 5 to rotate, and the sprocket 5 drives the chain 3. The chain 3 is a one-way bending structure and moves along the track of the guide rail 7, and...

The invention discloses a hidden type hand press. The hidden type hand press comprises an hand operated disc and a gear reducer, one side of the hand operated disc is connected with a crank and the other side of the hand operated disc is connected with a gear reducer, the output shaft of the gear reducer is connected with a chain wheel which is matched with a chain, the front end of the chain is connected with a fixed code, the rear end of the chain is connected with a chain tail limiting block, the chain is provided with a guide rail, and the guide rail, the chain wheel, the chain and the chain tail limiting block are arranged in a chain box. All the construction members are of a hidden type and hidden in a window frame and integrated with a window. The hidden type hand press has small size and very small occupied area. An execution part is of a chain type and operates very stably. The chain can be bent at the part of a machine, and therefore the internal structure space can be saved. The gear reducer has high transmission and reduction ratios and also has a self-locking function. The hidden type hand press has the advantages of simple structure, convenience for installation and high transmission efficiency and can be applied to a sliding widow and a pivot window.
Description
technical field [0001] The invention relates to a hand-operated window opening machine for opening and closing a sliding window or a swing window. Background technique [0002] The known manual window opener includes a base, a handle, a worm, a gear arm with a worm gear at the end, and a gear arm fixed shaft. The manual window opener is installed outside the window, which affects the appearance of the window; the structure is complex, and the switching force is small; the transmission efficiency is low, there are component forces in the transmission, and there is a lot of power loss during the transmission process (reference: Chinese patent Application number 200610030378.1 manual window opener). Contents of the invention [0003] In order to overcome the defects of inconvenient installation, complex structure and low transmission efficiency of the known manual window opener, the present invention provides a concealed manual drive, which is easy to install, simple...
