Description

Technical Field

[0001] The utility model relates to the technical field of top-opening windows. Background Art

[0002] In the dairy farming industry, top-opening windows are mainly used in large and small milking parlors, delivery pens and other units. They are installed at the top of the unit. They can be closed in winter to keep out the cold, and can resist rain, snow, wind and sand in the rainy and windy seasons. They can be opened when the weather is good, which plays an important role in ensuring the indoor temperature, adjusting the indoor air circulation and improving the indoor comfort.

[0003] The existing top-opening window is composed of a window body, a drive system and a control system. The drive system is the power output unit of the entire top-opening window, which is mainly composed of a reduction motor, a transmission shaft, a gear, a rack, etc. The specific structural form is that the reduction motor drives the transmission shaft, the transmission shaft is connected to the gear rack, the rack is connected to the window, and then the motor and the rotating shaft rotate to drive the gear to rotate, so as to realize the reciprocating motion of the rack up and down. When the rack moves upward, the window opens, and when the rack moves downward, the window closes. However, the existing structural form has some disadvantages. Since the installation of the transmission shaft and the gear is supported by a top screw, the top-opening window that has just been installed often runs relatively smoothly, but after running for a period of time, the top screw will loosen, that is, when the transmission shaft rotates, some gears will not rotate with it, so that some racks will push up, while some racks will not move, which eventually causes the entire window to be deformed by the top. Another situation is that this type of top-opening window is limited by the motor's own travel switch, and it will stop automatically when the travel is adjusted. However, when installing top-opening windows, temporary electricity is often used for debugging. When the formal electricity is finally connected, if you are not careful, the phase sequence will be reversed. In this way, the original positive phase will be reversed during operation, causing overall damage to the top-opening window (this is an extremely rare case, but it has happened). Utility Model Content

[0004] In view of the above situation, it is considered necessary to replace the driving system of the top-opening window with a more stable, reliable and safer system.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model provides a top-opening window, including a rotating mechanism arranged on a rod and a window body rotatably connected to both sides of the rotating mechanism, the rod is provided with a roof, the rod is provided with a push rod base between the roof and the rotating mechanism, and an electric push rod is connected between the push rod base and the window.

[0006] Preferably, the electric push rod is rotatably connected to the push rod base and the window body respectively.

[0007] Preferably, a sealing strip is provided at a free end of the window away from the rotating mechanism, and an edge that can cooperate with the sealing strip is provided at an end of the roof close to the rotating mechanism.

[0008] Preferably, a sealing top cloth is provided on the surface of the connection between the rotating mechanism and the window body.

[0009] Preferably, the sealing top cloth is transparent.

[0010] Preferably, the edge of the sealed top cloth is fixed to the window body via a pressure strip.

[0011] Preferably, the rod is provided with a screw driven by a motor assembly, the screw thread penetrates the push rod base, and the screw can be rotated to move the push rod base.

[0012] Preferably, an angle is formed between the rods located on both sides of the rotating mechanism, and the two rods are connected via a coupling, and the coupling is driven by the motor assembly.

[0013] Preferably, a net frame flipping mechanism is provided at the bottom of the end of the window body close to the rotating mechanism, and the net frame flipping mechanism is rotatably connected to multiple insect-proof net frames. The insect-proof net frame located at the top is arranged on the bottom surface of the window body, and the insect-proof net frame located at the bottom is connected to the roof, and insect-proof nets are provided between adjacent insect-proof net frames.

[0014] In summary, the utility model includes the following beneficial technical effects:

[0015] 1. More stable structure: The top-opening window opened by gear racks may cause some screws to loosen due to installation or long-term use, resulting in a series of problems, such as the window opening is not synchronized and the window is damaged, the rack falls off, etc. The use of electric push rods and synchronizers to open the top-opening window can avoid the above problems and make the overall structure more stable.

[0016] 2. The force on the window is more evenly distributed: The top-opening window opened by the original gear rack is controlled by the transmission shaft driving the rack to rise and fall to control the opening and closing of the window. The power output point is only one point of the motor. When it is opened by an electric push rod, the electric push rod is installed every 2 meters, which means that there is a power output point every 2 meters on the window, making the force on the window more evenly distributed.

[0017] 3. Avoid wrong phase sequence connection: The power supply voltage of the electric push rod is 48V to 220V, so there is no forward and reverse connection error, avoiding the occurrence of safety accidents.

[0018] 4. Stable stroke control: The stroke of the original top-opening window opened by the gear rack is controlled by the motor's own stroke, and there will be no problems in the short term, but it is inevitable that it will malfunction after a long period of use. It will not stop running when it is in place, which will cause irreversible damage to the top-opening window. When using an electric push rod to open it, as long as the push-out stroke distance is calculated, it will stop running when it reaches the position regardless of whether it is opened or closed. There will be no situation where it continues to run without stopping when it reaches the position, because the stroke of the electric push rod is so long, and it is impossible to let it continue to run when it is in place.
