Description

Technical Field

[0001] The utility model belongs to the technical field of door and window actuators, and specifically relates to a self-locking door and window actuator. Background Art

[0002] Door and window actuators are widely used. For example, in residential buildings where the elderly and disabled live, ordinary doors and windows are difficult to open and close. In this case, door and window actuators can be installed to open and close the doors automatically, making life more convenient. In commercial buildings such as shopping malls, hotels, hospitals and other public places, door and window actuators can realize automatic control of doors and windows.

[0003] The power source of the door and window actuator is usually an electric motor or a pneumatic device. The electric motor converts electrical energy into mechanical energy and provides power to the transmission device, thereby realizing the opening and closing of the doors and windows. The pneumatic device uses compressed air to generate power and transmits the power to the transmission device through devices such as cylinders. The transmission device is a device used to transmit power from the power source to the doors and windows, usually including gears, chains, belts, etc. Through these transmission devices, the power can be effectively transmitted to the doors and windows, thereby realizing the opening and closing operations of the doors and windows.

[0004] When doors and windows are opened automatically, a development board is often used to control a single or two cylinders to push the window sashes. These cylinders swing at a certain angle relative to the window sashes at the same time, and the connection between the two cylinders is often hinged and can rotate freely. Once the external airflow blows, the connection is difficult to self-lock and easily causes shaking. For this reason, we propose a self-locking door and window actuator. Utility Model Content

[0005] The utility model aims to provide a self-locking door and window actuator, which can automatically lock after the window is opened or closed, has good stability in the self-locking state, and is not easy to shake in the wind.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A self-locking door and window actuator, comprising a column and two cylinders, wherein a rotating yoke is fixed to the output end of one of the cylinders and its end is hinged to one side of the column, and the end of the other cylinder is hinged to the rotating yoke and fixed to a micro-electric cylinder, a brake pad is vertically fixed to the output end of the micro-electric cylinder, the brake pad and the rotating yoke are parallel to each other, two parallel movable plates are arranged above the rotating yoke, and the two movable plates are slidably connected, the upper end of one of the movable plates is hinged to the upper end of the column, and the lower surface of the other movable plate is hinged to the output end of the other cylinder, when the window is opened, the push rod of the micro-electric cylinder extends, driving the brake pad to disengage The yoke is rotated to release the locked state, and then the two cylinder piston rods are extended to push the two movable plates to swing outward around the upper end of the column. While the two slide away from each other, the window sash is flipped outward. There is one degree of freedom of swinging between the two cylinders around the rotating yoke, and there are two degrees of freedom of swinging relative to the column and the movable plate respectively. After the window sash is opened, the two cylinders are stopped and the micro-electric cylinder push rod is shortened to drive the brake pad to fit closely to the rotating yoke, and automatically lock it by friction. When closing the window, the locked state is also released, and the window sash can be driven to close by shortening the two cylinder piston rods. The window sash is in a self-locking state with good stability and is not easily shaken by wind.

[0008] A flange plate fixedly connected to the end of an adjacent cylinder is fixed on the outside of the micro-electric cylinder. One end of the flange plate extends into the opening of the rotating yoke and is rotatably connected to the rotating yoke. The flange plate can be connected between adjacent cylinders, rotating yokes and micro-electric cylinders, leaving space for the micro-electric cylinder to move and prevent interference.

[0009] A frosted sheet is fixed on one side of the rotating yoke close to the brake pad. The frosted sheet and the brake pad are parallel to each other. When the brake pad is close to the rotating yoke, it can press against the frosted sheet. The friction between the frosted sheet and the brake pad can achieve good braking and form a self-locking effect between the two cylinders.

[0010] A hinge seat is fixed at the lower end of a movable plate away from the column and is used to connect one end of the window frame. When the two movable plates swing relative to the column, they swing adaptively around the hinge seat as the window sash opens.

[0011] A mounting plate is fixed at the lower end of the column, and a plurality of pin holes are reserved, through which expansion screws can be passed and nailed into the wall for easy fixing.

[0012] A plurality of threading tubes are fixed on the outside of the column to lay the pipelines required for the cylinder and the micro electric cylinder so as to centrally arrange the wiring.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model discloses a self-locking door and window transmission device. When the window is opened, the micro-electric cylinder push rod extends, driving the brake pad to separate from the rotating yoke and release the locking state. Then, the two cylinder piston rods extend to push the two movable plates to swing outward around the upper end of the column. While the two slide away from each other, the window sash is flipped outward. There is a swinging freedom between the two cylinders around the rotating yoke, and there are two swinging freedoms relative to the column and the movable plate respectively. After the window sash is opened, the two cylinders are stopped, and the micro-electric cylinder push rod is shortened to drive the brake pad to be close to the rotating yoke, and the friction is used for automatic locking. When the window is closed, the locking state is also released. The window sash can be driven to close by shortening the two cylinder piston rods. The stability in the self-locking state is good and it is not easy to shake due to wind. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-4As shown, a self-locking door and window actuator includes a column 1 and two cylinders 2, wherein a rotating yoke 3 is fixed to the output end of one of the cylinders 2 and its end is hinged to one side of the column 1, and the end of the other cylinder 2 is hinged to the rotating yoke 3 and fixed to a micro-electric cylinder 4, and the micro-electric cylinder 4 and the two cylinders 2 are both connected to a Mitsubishi single-chip microcomputer by signal, and a brake pad 5 is vertically fixed to the output end of the micro-electric cylinder 4, and the brake pad 5 is parallel to the rotating yoke 3. Two parallel movable plates 6 are arranged above the rotating yoke 3, and the two movable plates 6 are slidably connected to each other, wherein the upper end of one movable plate 6 is hinged to the upper end of the column 1, and the lower surface of the other movable plate 6 is hinged to the output end of the other cylinder 2, and the column 1 is first vertically fixed to the inner edge of the window, aligned with one side of the window frame, and the lower end of the other movable plate 6 is hinged to one side of the window frame. , the micro-electric cylinder 4 and the two air cylinders 2 are controlled by a preset program. When opening the window, the push rod of the micro-electric cylinder 4 extends, driving the brake pad 5 to disengage from the rotating yoke 3 to release the locked state, and then the piston rods of the two air cylinders 2 extend to push the two movable plates 6 to swing outward around the upper end of the column 1. While the two slide away from each other, the window sash is flipped outward. There is a swinging freedom between the two cylinders 2 around the rotating yoke 3, and there are two swinging freedoms relative to the column 1 and the movable plate 6 respectively. After the window sash is opened, the two cylinders 2 are stopped, and the push rod of the micro-electric cylinder 4 is shortened, driving the brake pad 5 to close to the rotating yoke 3, and automatically locking by friction. When closing the window, the locked state is also released, and the piston rods of the two cylinders 2 are shortened to drive the window sash to close. The stability in the self-locking state is good and it is not easy to shake due to wind.

[0023] There is an angle between the two cylinders 2. After self-locking, they form a triangular stable structure, and the column 1 and the two movable plates 6 also form a triangular stable structure. When supporting each other, the structural strength is sufficient to support and hold the window sash and can withstand a certain degree of wind blowing. The cylinder 2 can use the MWB series locking pneumatic cylinder, and the equipped air path and air control system are existing technologies and are not drawn in the figure. The micro electric cylinder 4 can use the LAS10-023P model micro servo electric cylinder with a stroke of 10mm.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, a flange plate 7 fixedly connected to the end of the adjacent cylinder 2 is fixed on the outside of the micro-electric cylinder 4, one end of the flange plate 7 extends into the opening of the rotating yoke 3 and is rotatably connected to the rotating yoke 3, and the flange plate 7 can be connected between the adjacent cylinder 2, the rotating yoke 3 and the micro-electric cylinder 4, leaving space for the micro-electric cylinder 4 to move and prevent interference.

[0025] like Figure 1 , Figure 2 and Figure 4As shown, a frosting sheet 8 is fixed to one side of the rotating yoke 3 close to the brake pad 5, and the frosting sheet 8 and the brake pad 5 are parallel to each other. When the brake pad 5 is close to the rotating yoke 3, it can press against the frosting sheet 8, and the friction between the frosting sheet 8 and the brake pad 5 can effectively brake, forming a self-locking effect between the two cylinders 2.

[0026] like Figure 1 As shown, a hinge seat 9 is fixed to the lower end of a movable plate 6 away from the column 1 for connecting one end of the window frame. When the two movable plates 6 swing relative to the column 1, they swing adaptively around the hinge seat 9 as the window sash opens.

[0027] like Figure 1 As shown, a mounting plate 10 is fixed at the lower end of the column 1, and a plurality of pin holes are reserved, through which expansion screws can be passed to be nailed into the wall, which is convenient for fixing, has a large lateral supporting area, and is not easy to tilt.

[0028] like Figure 1 As shown, a plurality of threading tubes 11 are fixed on the outside of the column 1 to lay the pipelines required by the cylinder 2 and the micro-electric cylinder 4 so as to centrally arrange the wiring and avoid squeezing the pipelines when the actuator swings.

[0029] The working principle of the utility model is: when opening the window, the push rod of the micro-electric cylinder 4 is extended, driving the brake pad 5 to disengage from the rotating yoke 3 to release the locked state, and then the piston rods of the two cylinders 2 are extended to push the two movable plates 6 to swing outward around the upper end of the column 1. While the two slide away from each other, the window sash is flipped outward. There is a swinging freedom between the two cylinders 2 around the rotating yoke 3, and there are two swinging freedoms relative to the column 1 and the movable plate 6 respectively. After the window sash is opened, the two cylinders 2 are stopped, and the push rod of the micro-electric cylinder 4 is shortened, driving the brake pad 5 to be close to the rotating yoke 3, and automatically locking is performed by friction. When closing the window, the locked state is also released, and the piston rods of the two cylinders 2 are shortened to drive the window sash to be closed. The stability in the self-locking state is good and it is not easy to shake due to wind.

It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
