[0038] In a further embodiment of the utility model, the door and window buffer opening device is preferably installed on the handle opening side of the door and window, that is, one universal joint 1 is installed on the handle side inner frame of the inward opening door and window frame 301, and the other universal joint 1 is installed on the handle side outer surface of the inward opening door and window opening leaf 302.

[0039] In a further embodiment of the utility model, the gas spring is an elastic element using gas and liquid as working medium, and is composed of a pressure tube, a piston, a piston rod and a plurality of connecting parts.

[0040] In a further embodiment of the utility model, a gas spring is an accessory that can perform functions such as support, buffering, braking, height adjustment and angle adjustment. At present, the product has been widely used in the fields of medical equipment, automobiles, furniture, textile equipment, processing industry, etc. According to different characteristics and application fields, gas springs are also called support rods, angle adjusters, gas pressure rods, dampers, etc. The basic principle of the gas spring is to press inert gas or oil-gas mixture into a closed cavity. According to the structure and function of the gas spring, the gas spring mainly includes free-type gas springs, self-locking gas springs, random stop gas springs, traction gas springs, and dampers.

[0041] In a further embodiment of the utility model, the damper is widely used in automobiles and medical equipment, and its characteristic is that the resistance changes with the running speed, and can obviously damp the speed of the connected mechanism.

[0042] In a further embodiment of the utility model, the universal joint is a universal joint, which is a component for realizing variable angle power transmission. Its function is to transmit power from one rotating shaft to another rotating shaft within a certain angle variation range.

[0043] In a further embodiment of the utility model, the structure and use of the universal joint are like the joints on the human limbs, allowing the angle between the connected parts to change within a certain range. In order to meet the power transmission, adapt to the angle changes caused by the up and down bounces generated during the operation of the car, the drive axle of the front-drive car is often connected to the wheel axle by a universal joint.

[0044] In a further embodiment of the utility model, a buffered opening device for doors and windows is provided. This device is designed to solve the problem that the inward-opening doors and windows move toward the indoor side around the hinges at a faster speed due to the large indoor and outdoor air pressure difference. The characteristics of the damping gas spring 2 are utilized to enable the inward-opening doors and windows to achieve buffered opening under any air pressure conditions.

[0045] In a further embodiment of the utility model, the door and window buffer opening device is mainly composed of a damping gas spring 2 and a universal joint connector 102 at both ends. The damping gas spring 2 is tightly connected to the inner window frame and the fan through the universal joint connector base 101 using the inner window hardware installation position. Due to the characteristics of the universal joint 1 and the inherent stroke of the rod of the damping gas spring 2, the movement trajectory of the device can be coupled with the fan opening trajectory of the fan body using different types of hinges. The damping gas spring 2 can automatically adjust the connection angle during operation, thereby eliminating the lateral force during operation. The damping gas spring 2 has the characteristic that the resistance changes with the speed of operation, and can obviously buffer the speed of the connected mechanism. When the point of action of the force guiding the damping gas spring 2 moves faster, its resistance increases significantly. On the contrary, when the point of action moves very slowly, its resistance almost disappears. When the inner opening door and window is opened, regardless of its running speed, it can achieve a more comfortable door and window opening, while avoiding affecting the normal opening and closing of the door and window.

[0046] In a further embodiment of the utility model, when the inward opening door and window is opened, if the outdoor wind speed is high or a narrow channel effect (draft) occurs indoors, according to the Bernoulli principle, the outdoor surface pressure of the inward opening door and window sash will be lower than the indoor surface pressure, and the sash will close quickly when the wind brace is not installed. This process may also cause damage to people passing by or the sash. The device can control the speed of the sash closing, which plays a buffering role of the wind brace to a certain extent.

[0047] In a further embodiment of the utility model, the inwardly opening window sash is opened with buffering; the inwardly opening window sash is closed with buffering; and the device structure is simple and replaceable.

[0048] In a further embodiment of the utility model, a universal joint 1 is installed on the inward-opening door and window frame 301, and another universal joint 1 is installed on the inward-opening door and window opening fan 302. During the rapid opening and closing process of the inward-opening door and window opening fan 302 on the inward-opening door and window frame 301, the damping gas spring 2 acts as a buffer for the inward-opening door and window opening fan 302 to prevent the user from opening the inward-opening door and window. The large indoor and outdoor air pressure difference (outdoor air pressure is greater than indoor air pressure) may cause the inward-opening door and window fan to move toward the indoor side at a faster speed around the hinge, causing damage to the user who is performing the opening operation, the indoor structure or the door and window fan body itself.

[0049] In a further embodiment of the utility model, the door and window buffer opening device can be installed on the upper part, lower part or handle side of the door and window, or the door and window buffer opening device can be installed on the upper part and lower part of the door and window at the same time. The door and window buffer opening device has a simple structure and is installed at the inner window opening hardware installation position. There is no need to process a new assembly position space for the doors and windows, thereby avoiding interference with the opening and closing process of the doors and windows, and ensuring the sealing performance of the doors and windows.

[0050] In a further embodiment of the utility model, one end of the damping gas spring 2 is connected to the inward-opening door and window frame 301 through a universal joint 1, and the other end of the damping gas spring 2 is connected to the inward-opening door and window opening sash 302 through another universal joint 1, thereby realizing the free rotation between the damping gas spring 2 and the inward-opening door and window frame 301 and the free rotation between the damping gas spring 2 and the inward-opening door and window opening sash 302. During the opening and closing process of the inward-opening door and window opening sash 302, due to the characteristics of the universal joint 1 and the inherent stroke of the rod of the damping gas spring 2, the movement trajectory of the device and the opening trajectory of the sash body using different types of hinges can be coupled with each other. During the operation, the damping gas spring 2 can automatically adjust the connection angle with the inward-opening door and window frame 301 or the inward-opening door and window opening sash 302, thereby eliminating lateral forces during operation.

[0051] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
