Description

Technical Field

[0001] The utility model relates to the field of window openers, in particular to a manual clutch mechanism for window openers. Background Art

[0002] As people's living standards improve, their requirements for smart and comfortable living environments are getting higher and higher. Therefore, the degree of home automation is getting higher and higher. People often install window openers on windows to intelligently control the opening or closing of windows. Users can remotely control the windows, which is convenient and simple to use. Even when users are away from home, they can open or close windows at any time according to their needs.

[0003] The existing Chinese utility model patent with publication number CN218509284U discloses a manual and automatic integrated external arm-type window opener. When the clutch adjustment member rotates, it can push the clutch lifting frame in the adjustment rotating groove to slide along the adjustment rotating groove. When the clutch lifting frame enters the high platform from the low platform along the lifting step, since the axial height of the high platform is higher than that of the low platform, the clutch lifting frame will also rise, pushing the input main gear away from the input sub gear to disengage the clutch teeth and the clutch groove, so that the motor will not be affected when the window sash is manually opened and closed. When the clutch lifting frame enters the low platform from the high platform along the lifting step, the clutch lifting frame will also move downward, allowing the clutch teeth to fall into the clutch groove to complete the engagement, thereby realizing electric control, thereby avoiding the influence of the manual motor load, making manual opening and closing of the window sash more convenient, and extending the service life of the motor.

[0004] In the above technical solution, when the window opener needs to be clutch-adjusted, the corresponding clutch adjustment member needs to be taken out, and the clutch adjustment member is provided separately, which makes it easy to lose, and the whole clutch adjustment method is too complicated and inconvenient to use. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a manual clutch mechanism for a window opener in view of the deficiencies of the above-mentioned prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manual clutch mechanism for a window opener, comprising a box body, an input gear shaft and an output gear shaft arranged in the box body, a clutch movable shaft is arranged between the input gear shaft and the output gear shaft, a driving gear and a driven gear that can rotate on the outer circumference of the clutch movable shaft are axially mounted on the clutch movable shaft, the driving gear is meshed with the input gear shaft, the driven gear is meshed with the output gear shaft, a transmission structure that cooperates with each other to achieve linkage or separation is arranged between the driving gear and the driven gear, the One end of the clutch movable shaft corresponding to the driving gear is provided with a limiting ring platform which is linked with the axial lifting of the driving gear and thus approaches or moves away from the driven gear. A clutch control knob is provided after one end of the clutch movable shaft passes through the box body. A plurality of high-position platforms protruding in the direction away from one end of the driving gear are provided at the clutch control knob of the box body. The clutch control knob switches between the surface of the box body and the high-position platform. When the clutch control knob abuts against the surface of the box body, the driving gear and the driven gear are linked with each other. When the clutch control knob abuts against the high-position platform, the driving gear and the driven gear are separated from each other.

[0007] The above technical solution is adopted, wherein the input gear shaft and the output gear shaft are respectively linked with the main drive part and the transmission parts of the window opener. Under normal circumstances, the driving gear is linked with the driven gear through the transmission structure due to its own gravity, and the main drive part (electric or manual) drives the driving gear to rotate through the input gear shaft, and then the driven gear drives the transmission parts of the window opener through the output gear shaft to drive the window sash to open and close. However, if the window opener fails, it is necessary to manually open and close the window sash, pull it to the high platform through the clutch control knob, and then pull the clutch movable shaft upward, and the linkage limit ring platform The linkage driving gear is away from the driven gear, so that the transmission structure between the driving gear and the driven gear is released, and the driving gear and the driven gear are separated. At this time, the main drive part of the switch window sash will not be subjected to load, and the window sash can be opened and closed conveniently, which is convenient for escape in an emergency and improves safety. At the same time, when the clutch control knob returns to the surface of the box body on the high-position platform, the driving gear will also be reset to the linkage state due to its own gravity. Compared with the prior art, the clutch adjustment part is cancelled, and the clutch effect is realized by direct control of the integrally installed clutch control knob, which avoids loss, and the whole structure is simpler and more stable to use.

[0008] The above-mentioned manual clutch mechanism for a window opener can be further configured as follows: the transmission structure includes a plurality of clutch blocks or clutch grooves arranged at one end of the driving gear corresponding to the driven gear, and a clutch groove or clutch block arranged on the driven gear and correspondingly plugged into the clutch blocks or clutch grooves.

[0009] By adopting the above technical solution and the design of the clutch block and the clutch slot, the driven gear and the driving gear can stably achieve linkage and separation states, thereby improving the operating accuracy of the clutch mechanism.

[0010] The above-mentioned manual clutch mechanism for a window opener can be further configured as follows: the box body is provided with an inclined slide that gradually rises from the box body surface along the high platform at the high platform corresponding to the box body, and the clutch control knob is provided with a sliding protrusion at one end of the box body corresponding to the box body.

[0011] By adopting the above technical solution, the inclined slide provides a guide for the movement of the knob, so that the knob does not need to be lifted or pulled when switching the clutch, but can be directly rotated to make the sliding protrusion on the knob slide along the inclined slide, making the clutch switching of the knob smoother and more labor-saving.

[0012] The manual clutch mechanism for a window opener can be further configured as follows: an elastic member is provided between the box body and the driving gear, one end of the elastic member abuts against the box body, and the other end abuts against the driving gear, and causes the driving gear to move toward the driven gear.

[0013] By adopting the above technical solution, the elastic member provides a continuous elastic force to prompt the driving gear to move toward the driven gear and maintain linkage, thereby ensuring that the window opener equipped with the clutch mechanism can ensure the stability of the reset of the driving gear in any installation orientation.

[0014] The above-mentioned manual clutch mechanism for a window opener may be further configured as follows: both ends of the sliding protrusion have arc-shaped sliding surfaces.

[0015] By adopting the above technical solution, the arc-shaped sliding surface reduces the friction and wear of the knob during operation, so that it can slide more smoothly along the inclined slide table.

[0016] The manual clutch mechanism for a window opener may be further configured as follows: the surface of the elastic member corresponding to the box body and the driving gear has a spring positioning groove for installing the elastic member.

[0017] By adopting the above technical solution, the design of the spring positioning groove makes the installation of the elastic member more stable, so that the spring will not deviate during the clutch control process, thereby extending the service life.

[0018] The above-mentioned manual clutch mechanism for a window opener may be further configured as follows: the elastic member is a spring, and a spring gasket is further provided between the driving gear and the spring.

[0019] By adopting the above technical solution, the spring gasket can absorb impact, reduce direct metal contact between the gear and the spring, extend the service life, reduce friction, and make the rotation smoother.

[0020] The manual clutch mechanism for a window opener may be further configured as follows: a lifting groove is provided at one end of the driving gear corresponding to the driven gear, and the limiting ring is arranged in the lifting groove.

[0021] By adopting the above technical solution, the lifting groove allows the limit ring to be installed inside, which is convenient for it to drive the active gear to move up and down axially, making its clutch control more stable and the rotation smoother in the linkage state.

[0022] The manual clutch mechanism for a window opener can be further configured as follows: the driving gear is provided with four clutch blocks equidistantly distributed around the clutch movable shaft, and the driven gear is provided with four clutch grooves correspondingly engaged with the clutch blocks.

[0023] By adopting the above technical solution, the evenly distributed clutch blocks and clutch slots provide stable linkage and separation, so that the driving gear and the driven gear that need to be re-linked after separation can be easily reset and plugged after rotating to different positions, thereby achieving stable linkage.

[0024] The manual clutch mechanism for a window opener may be further configured as follows: shaft sleeves are provided at both ends of the clutch movable shaft corresponding to the box body.

[0025] By adopting the above technical solution, the shaft sleeve reduces the direct contact between the clutch movable shaft and the box body, reduces wear, protects the clutch movable shaft, and prolongs its service life.

[0026] The utility model will be further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
