Description

Technical Field

[0001] The utility model relates to the technical field of window openers, in particular to a window opener with replaceable stroke components. Background Art

[0002] Doors and windows, as an important part of buildings, provide functions such as daylighting, ventilation, and isolation for the indoor space of buildings. In the prior art, doors and windows include door and window frames and door and window sashes. The door and window frames are fixed to the walls of buildings, and the door and window frames and door and window sashes are hinged through a hinge shaft. The door and window sashes can rotate around the axis of the hinge shaft to realize the opening and closing of the doors and windows. Common window sashes are usually opened and closed manually, and later, window sashes that are opened and closed mechanically also appeared.

[0003] A machine used to open and close the sashes of windows is called a "window opening actuator" or "window opener", which belongs to high-tech products in the domestic building doors, windows, and curtain wall industries. Its applications mainly include: windows that are inconvenient to open and close manually due to their high positions; windows with special functions such as fire smoke exhaust, fire linkage, or ventilation requirements; windows in intelligent control scenarios such as building automation control and smart home control. Currently, existing window opening actuators are divided into manual, pneumatic, and electric types. Electric actuators include screw window openers, crank arm window openers, chain window openers, etc. The screw window opener uses a motor to drive a screw to rotate. The screw is connected to a rod body, driving the rod body to reciprocate telescopically. The other end of the rod body is connected to the frame of the window sash. The telescopic movement of the rod body drives the opening or closing of the window sash. The rod body and the frame are connected through a support head. The support head is usually fixed to the frame, and then a rotating shaft structure is used to rotatably connect the support head to the window sash joint of the rod body, so that after the window sash is opened at a certain angle, it can still maintain a normal connection with the window opener.

[0004] Due to different requirements for the size, weight, and opening amplitude of window sashes, window openers with different lengths need to be configured for different window sashes; installation and construction personnel need to customize and purchase different models of window openers to meet the needs of different customers, different windows, and different scenarios, and there are certain inconveniences in carrying, transporting, and installing.

[0005] Therefore, how to optimize and improve based on the existing window openers to meet the requirements of window openers with different stroke lengths is a technical problem that needs to be solved. Summary of the Utility Model

[0006] The utility model aims to provide a technical solution to overcome the above deficiencies.

[0007] The utility model provides a window opener with replaceable stroke components, which includes a power component and a stroke component. One end of the power component is installed on an external window frame; the other end is connected to the stroke component. One end of the stroke component is installed on an external window sash, and the other end is detachably and replaceably connected to the power component and forms a transmission connection with the power component, so that when the power component operates, it can drive the stroke component to operate synchronously, thereby changing the length of the stroke component, and further performing opening and closing operations on the external window sash; the stroke component has various specification models with different stroke lengths, and the stroke components with different stroke lengths are respectively detachably and replaceably connected to the power component, so as to perform opening and closing operations with different stroke lengths on the external window sash.

[0008] As a further scheme of the utility model: The power component and the stroke component are connected by threads, so as to form a fixed connection that is convenient for disassembly and replacement.

[0009] As a further scheme of the utility model: One end of the power component connected to the stroke component is provided with a first internal thread, and one end of the stroke component connected to the power component is provided with a first external thread. The power component and the stroke component form a detachable and replaceable threaded connection through the mutual cooperation of the first internal thread and the first external thread.

[0010] As a further scheme of the utility model: The power component is provided with a first housing, a power motor and a reducer respectively fixed to the first housing. The input shaft of the reducer is drivingly connected to the output shaft of the power motor, and the output shaft of the reducer is drivingly connected to the stroke component.

[0011] As a further scheme of the utility model: The stroke component is provided with a second housing and a transfer column fixedly connected to each other. One end of the transfer column is fixedly connected to the second housing, and the other end is detachably and replaceably connected to the power component.

[0012] As a further scheme of the utility model: The two ends of the transfer column are respectively provided with a first external thread and a second external thread. The inner side of the second housing is provided with a second internal thread, and the second internal thread of the second housing and the second external thread at one end of the transfer column cooperate with each other to form a threaded connection.

[0013] As a further scheme of the utility model: The stroke component is further provided with a screw rod, a nut and a sleeve. One end of the screw rod is rotatably connected to the transfer column and forms a transmission connection with the power component. The other end of the screw rod penetrates into the internal space of the sleeve. The nut is sleeved on the screw rod and forms a transmission connection with the screw rod. One end of the sleeve is fixedly connected to the nut, and the other end extends out of the second housing, so as to be installed on the external window sash.

[0014] As a further solution of the utility model: a counterbore is provided at one end of the screw rod drivingly connected to the power component, and the counterbore is provided with a cross-sectional shape matching the output shaft of the power component. After the stroke component is installed on the power component, the counterbore is sleeved on the output shaft of the power component, so that when the power component operates, the screw rod is driven to rotate synchronously.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. By optimizing and improving the power component and the stroke component that were originally fixed by bolts and not easy to disassemble, the disassembly and replacement between the two are made convenient, so that the power component with a certain size can be disassembled and replaced with a variety of stroke components with different stroke lengths, and then the corresponding stroke length can be replaced according to the window sashes with different sizes, different weights or different opening amplitudes. The installation and construction personnel only need to customize and purchase the power components of the same model and specification, and then match and replace the corresponding stroke components with different stroke lengths, so as to meet the needs of different customers, different windows and different scenarios, and the carrying, handling and installation are all more convenient.

[0017] 2. The connection mode between the power component and the stroke component can also be set as a thread connection that is convenient for disassembly and replacement. When it is necessary to install or use stroke components with different stroke lengths, the stroke component can be conveniently fixed on the power component by rotating, improving the efficiency of replacement and installation.

[0018] 3. A counterbore can also be provided at one end of the screw rod. The output shaft of the reducer can be inserted into the counterbore for a certain distance first, so that the output shaft can form a driving connection with the screw rod through the cooperation of the counterbore. When the stroke component is spirally installed on the power component, the output shaft of the reducer can form a correct driving connection with the screw rod, so that the power component can drive the screw rod to rotate, and then drive the nut to move and drive the sleeve to move synchronously to realize the opening or closing of the window sash.

[0019] Therefore, through the above improvements, the utility model can provide a window opener with replaceable stroke components, so that the power component can replace stroke components with different stroke lengths according to needs, and thus be applied to window sashes with different sizes, different weights or different opening amplitudes, making the carrying, handling and installation of the window opener more convenient.

Specific embodiments

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 5, in the embodiment of the present utility model, a window opener with replaceable stroke components includes a power component 10 and a stroke component 20. One end of the power component 10 is installed on the external window frame; the other end is connected to the stroke component 20. One end of the stroke component 20 is installed on the external window sash, and the other end is detachably connected to the power component 10 and forms a transmission connection with the power component 10, so that when the power component 10 operates, it can drive the stroke component 20 to operate synchronously, thereby changing the length of the stroke component 20, and further performing opening and closing operations on the external window sash; the stroke component 20 has various specifications with different stroke lengths, and the various stroke components 20 with different specifications can be respectively detachably connected to the power component 10, so as to perform opening and closing operations with different stroke lengths on the external window sash.

[0031] Specifically, when the traditional window opener leaves the factory, its power component 10 and stroke component 20 have been assembled and fixedly installed together. Usually, holes are drilled in the housing, and bolts are passed through the holes and fixedly connected to the internal mechanism, making their connection relatively stable, but it is not convenient for disassembly and replacement. Moreover, after the power component 10 and the stroke component 20 are assembled together, their length is relatively long, which is not convenient for handling and storage.

[0032] In particular, due to the different requirements for the size, weight, and opening amplitude of the window sash, window openers with different lengths need to be configured for different window sashes; installation and construction personnel need to customize and purchase different models of window openers to meet the needs of different customers, different windows, and different scenarios, and there are many inconveniences in carrying, handling, and installation.

[0033] Therefore, through research and improvement, the present utility model proposes that the power component 10 and the stroke component 20 can be set to be detachably replaceable, and the power component 10 and the stroke component 20 can be packaged separately when leaving the factory, so as to reduce the length of the window opener, making it convenient for storage, handling, and storage. And during specific installation, according to different conditions such as the specific size, specific weight, or specific opening amplitude of the window sash to be installed currently, a suitable stroke component 20 with a corresponding stroke length can be selected and quickly installed on the power component 10 to form a window opener after assembly.

[0034] Secondly, after using for a relatively long time, the requirements for the opening amplitude of some window sashes may change. Therefore, it is only necessary to directly replace the stroke component 20 with a different stroke length, without the need to replace the entire window opener, which can not only improve the replacement efficiency but also save the replacement cost.

[0035] Such as Figure 1 and Figure 5As shown, preferably, the power component 10 and the stroke component 20 are connected by a threaded connection, thereby forming a detachable and replaceable fixed connection. One end of the power component 10 connected to the stroke component 20 is provided with a first internal thread 12, and one end of the stroke component 20 connected to the power component 10 is provided with a first external thread 24. The power component 10 and the stroke component 20 form a detachable and replaceable threaded connection through the mutual cooperation of the first internal thread 12 and the first external thread 24. The power component 10 is provided with a first housing 11, a power motor 13 and a speed reducer 14 respectively fixed to the first housing 11. The input shaft of the speed reducer 14 is drivingly connected to the output shaft of the power motor 13, and the output shaft of the speed reducer 14 is drivingly connected to the stroke component 20.

[0036] Specifically, in order to quickly replace and assemble the stroke component 20, preferably, the power component 10 and the stroke component 20 are set to be connected by a threaded connection. By using the advantage that the threaded connection can be simply rotated to be removed or assembled, the convenience during replacement or installation can be improved, and the efficiency of replacement and installation can be increased. In addition, for the external aesthetics of the window opener, preferably, the first internal thread 12 is provided inside one end of the first housing 11 connected to the stroke component 20.

[0037] As Figures 3 to 5 As shown, preferably, the stroke component 20 is provided with a second housing 21 and a transfer column 23 fixedly connected to each other. One end of the transfer column 23 is fixedly connected to the second housing 21, and the other end thereof is detachably and replaceably connected to the power component 10. The two ends of the transfer column 23 are respectively provided with a first external thread 24 and a second external thread 25. The second internal thread 22 is provided inside the second housing 21. The second internal thread 22 of the second housing 21 and the second external thread 25 at one end of the transfer column 23 cooperate with each other to form a threaded connection; the first external thread 24 at the other end of the transfer column 23 and the first internal thread 12 of the power component 10 cooperate with each other to form a threaded connection.

[0038] Specifically, the transfer column 23 can play the role of respectively fixedly connecting the power component 10 and the stroke component 20. Therefore, external threads can be respectively provided at both ends thereof, and corresponding detachable fixed connections are formed through the mutual cooperation of the external threads and the internal threads. It can be understood that a sealing ring can also be provided in the middle of the transfer column 23. When the first housing 11 and the second housing 21 are fixed to the transfer column 23 by a threaded connection, the sealing ring can perform corresponding sealing settings on the first housing 11 and the second housing 21. Similarly, for the aesthetics of the window opener, preferably, the second internal thread 22 is provided inside one end of the second housing 21 connected to the power component 10.

[0039] As Figures 3 to 5As shown, preferably, the stroke component 20 is further provided with a screw 31, a nut 33 and a sleeve 34. One end of the screw 31 is rotatably connected to the adapter post 23 and is in transmission connection with the power component 10. The other end thereof penetrates into the inner space of the sleeve 34. The nut 33 is sleeved on the screw 31 and is in transmission connection with the screw 31. One end of the sleeve 34 is fixedly connected to the nut 33 and moves axially along the second housing 21 together with the nut 33. The other end thereof extends out of the second housing 21 so as to be installed on an external window sash. A counterbore 32 is provided at one end of the screw 31 that is in transmission connection with the power component 10. The counterbore 32 has a cross-sectional shape matching the output shaft of the power component 10. After the stroke component 20 is installed on the power component 10, the counterbore 32 is sleeved on the output shaft of the power component 10, so that the power component 10 operates to drive the screw 31 to rotate synchronously.

[0040] Specifically, in order to enable the stroke component 20 to be better assembled on the power component 10, a certain chamfer (not shown in the figure) can also be provided at the entrance of the counterbore 32 to make its entrance in a flared shape, so that the output shaft of the reducer 14 can be conveniently inserted into the counterbore 32, thereby forming a transmission connection with the screw 31. It can be understood that when assembling the stroke component 20 and the power component 10, preferably, the front section of the output shaft of the reducer 14 is first inserted into the counterbore 32 to form a directional insertion. Subsequently, when rotating the stroke component 20 or the power component 10 to form a fixed connection through threaded connection, the counterbore 32 can maintain a transmission connection with the output shaft of the reducer 14.

[0041] Secondly, a window sash joint 35 can also be fixedly connected to the end of the sleeve 34 extending out of the second housing 21. The window sash joint 35 can be used to connect with the support head of the external window sash, usually for shaft connection, so that it can rotate relative to the window sash by a certain angle. In addition, in order to make the sleeve 34 extend out of the housing more smoothly, a stabilizing ring 37 can also be provided at the end of the second housing 21 away from the power component 10. The outside of the stabilizing ring 37 is fixed at the port of the second housing 21, and its inside abuts against the sleeve 34. A material or component facilitating sliding can also be provided on the inside, so that the sleeve 34 can move smoothly along the stabilizing ring 37.

[0042] Thirdly, corresponding sliders 36 can also be provided at the end of the sleeve 34 fixedly connected to the nut 33. The sliders 36 are fixed on the nut 33, so that the nut 33 can drive the sliders 36 to move on the inner wall of the second housing 21, so that the sleeve 34 can stably and smoothly expand and contract on the inner wall of the second housing 21.

[0043] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
