Description

Technical Field

[0001] The utility model provides a centrally mounted extension-arm type window opener, belonging to the technical field of auxiliary window opening and closing equipment. Background Art

[0002] The machine used to open and close windows is called a window opener. Among them, the hand-operated window opener is generally suitable for opening and closing the middle-hung or top-hung skylights and side windows of industrial plants, warehouses, station waiting rooms, terminal buildings, theaters, auditoriums, canteens and other buildings. They are connected to each other by linkage transmission rods. When opening and closing multiple rows of side sashes, the upper window opener is mainly used to open and close the highest row of sashes, while the opening and closing of the middle rows of sashes is completed by the middle window opener. The output shaft of the middle or upper window opener is equipped with a transmission rod and a window opener, which is connected to the window sash to realize the opening and closing of the window sash.

[0003] The existing window opener can basically meet the needs of matching with the window opener, but there are still certain defects. When in use, the window opener is often only installed on the lower side of the side wall of the window sash, resulting in poor stability in opening and closing of the window sash, and the window sash cannot be locked in the window frame when closed; and it is difficult to achieve self-locking of the window sash during use, resulting in the window sash opening and closing when the wind or other external forces push the window sash, and the use effect needs to be improved. Based on this, the utility model provides a centrally mounted arm-type window opener. Utility Model Content

[0004] The technical problem solved by the utility model is that the window opener is often only installed on the lower side of the side wall of the window sash, resulting in poor stability in opening and closing of the window sash. There is a situation where the window sash cannot be closed in the window frame when closed, and it is difficult to achieve self-locking of the window sash during use, resulting in the window sash opening and closing when pushed by wind or other external forces. The use effect needs to be improved.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a centrally mounted arm-type window opener, comprising a window frame, one side wall of the window frame being rotatably connected to a matching window sash, the window frame side walls being symmetrically provided with window openers on the upper and lower sides, and the window sash side walls being symmetrically provided with slide grooves matching the window openers on the upper and lower sides, the window opener comprising an upper shell and a lower shell, a worm being rotatably connected between the upper shell and the lower shell, one side of the inner bottom wall of the lower shell being rotatably connected to a main gear, the top of the main gear being provided with a worm wheel meshing with the worm, the center of the inner bottom wall of the lower shell being rotatably connected to a slave gear meshing with the main gear, the top of the slave gear being provided with a supporting column, the top of the supporting column being provided with a limiting square plate, the top of the supporting column being provided with a rocker arm placed on the top of the upper shell and being clamped and connected with the limiting square plate, the end of the rocker arm being rotatably connected to a pulley slidably connected to the slide groove

[0006] Furthermore, the upper shell and the lower shell are fixedly connected by four sets of screws symmetrically arranged, and one end of the two side walls of the upper shell and the lower shell is symmetrically provided with mounting seats installed on the side walls of the window frame.

[0007] Furthermore, a through hole through which the worm passes is formed between the upper shell and the lower shell, and the worm and the through hole are rotatably connected via a bearing.

[0008] Furthermore, two ends of the worm are symmetrically provided with hexagonal positioning rods placed outside the upper shell and the lower shell.

[0009] Furthermore, a through hole is provided in the center of the top of the upper shell, a threaded hole is provided in the center of the limiting square plate that penetrates into the support column, a limiting square hole is provided at the end of the rocker arm away from the pulley that matches the limiting square plate, and a screw 2 matching the threaded hole is provided on the top of the rocker arm.

[0010] Furthermore, the bottom of the main gear and the bottom wall of the lower shell, as well as the top of the worm gear and the top wall of the upper shell are rotatably connected via two bearings.

[0011] Furthermore, the bottom of the gear and the bottom wall of the lower shell, and the support column and the top wall of the upper shell are rotatably connected by bearings.

[0012] Beneficial effects of the utility model:

[0013] The worm is driven to rotate by an external transmission rod, and the meshing connection between the worm and the worm wheel drives the worm wheel to rotate, which in turn drives the main gear to rotate. Under the meshing connection between the main gear and the slave gear, the slave gear is driven to rotate, which drives the support column to rotate, and then drives the limit square plate and the rocker arm to rotate. The rotation of the rocker arm drives the pulley to move in the slide groove, thereby realizing the opening and closing of the window sash, and can realize the opening and closing of multiple window sashes at the same time, saving time and effort, and reducing the fatigue intensity of the staff. By arranging the window opener in the center of the upper and lower sides of the window frame side walls, the stability of the opening and closing of the window sash is enhanced to prevent the window sash from being unable to be closed in the window frame when closed, and self-locking is achieved under the worm and worm gear structure. When the window sash is pushed by wind or other external forces, it will not cause the window sash to open and close, and the use effect is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS
