Description

Suspended vibration-damping noise-reducing window

Technical Field

The invention relates to a window, in particular to a hanging type vibration-damping noise-reducing window.

Background

Existing windows, including general building doors and windows, or automobile windows, etc., can be mainly categorized into two types: the window capable of being pushed and pulled to open and close to realize ventilation and the window which is completely fixedly connected on the wall surface and can not realize ventilation. The sliding window generally has the problems of large fit clearance and complex connection relationship, on one hand, the problem of noise transmission from outside and on the other hand, the problem of noise generation caused by the vibration of the window glass due to the transmission of external vibration. The window of complete rigid coupling has realized that external noise cuts off completely, but window glass itself combines closely with the wall and causes the transmission of vibration to window glass more directly, and window glass vibration noise is more obvious, and complete rigid coupling window can not realize ventilation moreover, produces indoor outer pressure differential easily, causes dizzy. In summary, it is important to design a vibration-damping noise-reducing window which can be opened and closed freely, has fewer vibration transmission paths, and has good sealing performance in a closed state.

The invention patent of the patent number 201120300126.2 in China discloses a novel window. The novel window is provided with more than four window frame cavities on the window frame body, so that the window is a circle surrounding the window body, and the strength and the sealing noise reduction effect of the window can be obviously improved. However, this design does not have a transmission path that fundamentally reduces noise, and sealing is still achieved by the sealing strip, which cannot be guaranteed to be in close contact with the glass all the time for long-term use.

Disclosure of Invention

The invention aims to solve the technical problem of providing the suspended vibration-damping noise-reducing window which can realize opening and closing, has fewer external vibration transmission paths to window glass, ensures effective restraint to the window glass in the closed and open states and has better sealing performance in the closed state.

In order to solve the technical problems, the suspended vibration-damping noise-reducing window provided by the invention consists of a window frame, a hinge, window glass and a gas/liquid type sealing loop; the window frame is fixedly connected to the window base; the top of the inner wall of the window frame is provided with a plurality of hollow guide sliding grooves with the same number as that of the window glass; the upper part of the hinge is a cylinder and can be embedded into the hollow guide chute; the window glass is riveted with the lower part of the hinge by rivets, so that the window glass is hung on the window frame; the periphery of two sides of the window glass is provided with a gas/liquid type sealing loop.

The window frame comprises an upper cross beam, a lower cross beam, a front side beam and a rear side beam which are fixedly connected with each other to form a whole, grooves facing to window glass are formed in the cross sections of the upper cross beam, the lower cross beam, the front side beam and the rear side beam, a partition which is one less than the number of the window glass is arranged in the window frame, the partition separates hollow guide sliding grooves on two sides of the window frame, and three middle beams are used for supporting and fixing the middle of the window frame and fixedly connected with the window frame.

Each hollow guide chute penetrates through the upper cross beam along the longitudinal direction, the hinge can longitudinally slide back and forth along the hollow guide chute after the cylinder at the upper part of the hinge is embedded into the hollow guide chute, so that window glass is closed or opened, and meanwhile, the cylinder at the upper part of the hinge can axially rotate along the cylinder at the upper part of the hinge in the hollow guide chute, so that the window glass can swing freely after being disturbed.

The gas/liquid type sealing loop is stuck on the side wall of the groove, the partition side wall and the side wall of the middle beam at the junction of the window glass, the gas/liquid type sealing loop is stuck on the periphery of two sides of the window glass in a closed state, the gas/liquid type sealing loop is a closed loop, gas or liquid is filled in the gas/liquid type sealing loop, and the gas/liquid type sealing loop can flow freely in the window glass under the pressing action of the window glass.

After the structure is adopted, the window glass of the window is hung in the hollow guide chute of the window frame through the hinge, so that the window glass can be freely opened and closed like a common window; meanwhile, the hanging characteristics of the window glass and the window frame are connected only through the hinge, so that the transmission path of external vibration to the window glass is effectively reduced; the air/liquid type sealing loop ensures the tightness of the window in a closed state, and can prevent external noise from being transmitted into the window; meanwhile, the gas/liquid type sealing loop ensures effective restraint on the window glass in the closed and open states, and the elasticity and damping effect generated by the gas in the gas/liquid type sealing loop can reduce the vibration of the window glass, so that the vibration and noise reduction effects on the window in each state are realized.
