Description

Technical Field

[0001] The utility model belongs to the technical field of sound insulation windows, and particularly relates to a sound insulation window for high-noise areas. Background Art

[0002] An aluminum alloy window is a window body with an aluminum alloy as the window frame. According to its functions, it can be divided into a window body with a hinged opening method and a window body with a push-open method.

[0003] Among them, the window body that is opened in a push-pull manner is a push-pull window, and its internal window sash realizes push-pull opening by means of the cooperation of a track and a rail. Since the push-pull window has a simple opening method and occupies a small space after being opened, it is widely used in actual applications.

[0004] Sound insulation windows mostly use thickened glass plates as the glass of the window body. Since thickened glass plates such as tempered glass plates can isolate noise, they are the most commonly installed in actual life. The push-pull window also uses a relatively thick tempered glass plate as the glass on the window body structure.

[0005] At present, push-pull windows all have a single window body structure. However, it has been found in actual work that for push-pull windows installed in large window openings, the glass plate on the window body structure occupies a relatively large area of the window opening. Therefore, its noise isolation effect is not ideal. The reason is that the window opening is too large, resulting in too little concrete wall structure with strong sound insulation effect, and the penetrability of sound through the glass plate is higher than that of the concrete wall structure. Therefore, in actual work, it has been found that when a large-area push-pull window is installed in a building structure, such as on a balcony, when the external environmental noise is relatively large, the interior can still be disturbed by the noise.

[0006] Therefore, in areas with relatively high noise, such as building structures near railway stations, after installing traditional push-pull windows, sound can still penetrate through the push-pull windows. Especially at night when it is quiet, the noise between the interior and the exterior is very obvious to the human senses.

[0007] Therefore, a single-layer push-pull window is not suitable for installation on building structure systems in high-noise areas with large window openings.

[0008] However, the aesthetics and convenience of use of push-pull windows are not possessed by the traditional flip-open window body structure. Content of the Utility Model

[0009] Based on the above background, the purpose of the utility model is to provide a sound insulation window for high-noise areas.

[0010] To achieve the above purposes, the utility model adopts the following technical solutions:

[0011] A soundproof window for high-noise areas, comprising a sliding window body, the sliding window body including an outer window frame and a sliding window installed within the outer window frame; the soundproof window for high-noise areas further includes a secondary soundproof window mechanism hinged to the inner side of the outer window frame, the secondary soundproof window mechanism including an aluminum alloy secondary window frame, and a soundproof glass plate fixedly connected within the aluminum alloy secondary window frame;

[0012] The upper end of the aluminum alloy secondary window frame is hinged to the upper end of the outer window frame, and a spring return assembly is assembled and connected between the upper end of the aluminum alloy secondary window frame and the top of the outer window frame;

[0013] The spring return assembly includes a plurality of bent springs, and both ends of the bent springs are respectively fixedly connected to the top of the outer window frame and the upper end position of the aluminum alloy secondary window frame;

[0014] The spring return assembly further includes a support rod cooperating with the bent spring, and the support rod is fixedly connected to the top of the outer window frame;

[0015] During the process of flipping and closing the secondary soundproof window mechanism, the bent spring bends and pulls with the support rod as a fulcrum. With the assistance of the elastic restoring force of the bent spring, during the process of opening the secondary soundproof window mechanism, the bent spring pulls back the secondary soundproof window mechanism, achieving labor-saving opening.

[0016] Preferably, supports are respectively fixedly connected to the front and rear ends of the support rod, and the supports are fixedly connected to the right side of the top of the outer window frame.

[0017] Preferably, hinge shafts are fixedly connected to the upper ends of the front and rear side walls of the aluminum alloy secondary window frame, and a hinge seat for hinging the hinge shafts is fixedly connected to the upper end of the right side wall of the outer window frame.

[0018] Preferably, the outer window frame and the aluminum alloy secondary window frame are connected through a plurality of elastic buckle structures. Preferably, the elastic buckle structures are distributed at the front and rear side positions of the outer window frame and the aluminum alloy secondary window frame

[0019] Preferably, the elastic buckle structure includes a strip-shaped lock projection installed on the outer side wall of the outer window frame, and a bayonet matching the strip-shaped lock projection is provided on the aluminum alloy secondary window frame.

[0020] Preferably, a plurality of elastic lock heads are assembled and connected to the front and rear side walls of the strip-shaped lock projection. The elastic lock head includes a curved lock head portion, the lock head portion is integrally formed with a cylindrical sliding portion, a cylindrical groove for slidingly connecting the cylindrical sliding portion is provided on the strip-shaped lock projection, and an inner spring is fixedly connected to the cylindrical sliding portion, and the inner spring is fixedly connected in the cylindrical groove.

[0021] Preferably, a curved groove matching the lock head portion is provided on the inner side wall of the bayonet. When the strip-shaped lock projection is inserted into the bayonet, the lock head portion elastically presses against the curved groove; the lock head portion can slide and fall off along the curved groove.

[0022] Preferably, a sunk groove adapted to the strip lock projection is formed on the outer window frame. At both ends within the sunk groove, there are short columns fixedly connected and slidably connected within the strip lock projection. A small spring is sleeved on the short columns, and both ends of the small spring are fixedly connected to the inner side wall of the strip lock projection and the bottom of the sunk groove respectively;

[0023] Press the strip lock projection, and the strip lock projection disengages from the bayonet and elastically moves towards the sunk groove. During the process of pressing the strip lock projection to disengage from the bayonet, the lock head retracts into the strip lock projection and slides off along the curved groove.

[0024] The utility model has the following beneficial effects:

[0025] 1. During the process of flipping and closing the secondary sound insulation window mechanism (i.e., the downward flipping process), the bent spring bends and pulls with the support rod as the fulcrum (during this process, due to the gravity of the secondary sound insulation window mechanism acting downward, the downward flipping is relatively easy). However, the upward flipping to open overcomes gravity and is relatively strenuous. Therefore, during the downward flipping and closing, the bent spring bends and pulls to form a spring reset force. During the upward flipping and opening process, the restoring force of the bent spring is utilized to achieve labor-saving opening in the auxiliary state.

[0026] Through the above method, the technical defect of poor sound insulation effect of traditional single-sliding windows is solved, and a glass retaining wall formed by the secondary sound insulation window mechanism is used for protection. Moreover, the defects of difficult closing and opening of the heavy secondary sound insulation window mechanism are solved.

[0027] 2. During the opening process, when the hand presses the strip lock projection, the strip lock projection disengages from the bayonet and elastically moves towards the sunk groove. During the process of pressing the strip lock projection to disengage from the bayonet, the lock head retracts into the strip lock projection and slides off along the curved groove.

[0028] Specifically, during the process of the hand pressing the strip lock projection, at this time, the lock head of the curved structure slides relative to the curved groove with a slightly larger relative size until the lock head completely disengages from the curved groove.

[0029] After the pressing operation, due to the upper end of the aluminum alloy secondary window frame being pulled by the reset of the bent spring, the aluminum alloy secondary window frame is slightly flipped to have a certain gap with the outer window frame. This method prevents the strip lock projection from re-locking into the bayonet after the hand releases the pressing.

[0030] Through the above method, the aluminum alloy secondary window frame is locked and unlocked with the outer window frame in a simple and easy-to-operate manner. Moreover, the stability after locking is high, and unlocking is convenient, greatly improving its use flexibility. Description of the Drawings

[0043] Embodiment 1

[0044] As Figures 1-7 shown, a sound-insulating window for a high-noise area includes a sliding window body, which is a conventional aluminum alloy sliding window disclosed in the prior art. Its specific structure is the same as that of the existing aluminum alloy sliding window, including an outer window frame 1 installed in the window opening and a sliding window 2 installed inside the outer window frame 1. The sliding window 2 is slidably connected inside the outer window frame 1 by means of a slide rail and a rail groove.

[0045] To solve the technical defect that after installing a large-area sliding window in a high-noise area, the indoor noise level is high, the above-mentioned sound-insulating window for a high-noise area further includes a secondary sound-insulating window mechanism hinged to the inner side of the outer window frame 1. Specifically, the secondary sound-insulating window mechanism is opened and closed in a flipping manner. When in the closed state, double-layer protection is achieved, thereby further significantly reducing the noise entering the room. That is, the secondary sound-insulating window mechanism is equivalent to a glass retaining wall blocking inside the sliding window, and in this way, after installing a large-area sliding window, the indoor noise level is fully reduced.

[0046] Specifically, the secondary sound-insulating window mechanism includes an aluminum alloy secondary window frame 4, and a sound-insulating glass plate is fixedly connected inside the aluminum alloy secondary window frame 4. The sound-insulating glass plate is a thickened tempered glass plate.

[0047] Specifically, in order not to affect the normal operation of the sliding window body, the aluminum alloy secondary window frame 4 is installed in a flipping manner, that is, after flipping open the aluminum alloy secondary window frame 4, the sliding window body is exposed, which is convenient for the normal operation of the sliding window body. Conversely, after closing the aluminum alloy secondary window frame 4, the glass retaining wall is realized.

[0048] Specifically, the upper end of the aluminum alloy secondary window frame 4 is hinged to the upper end of the outer window frame 1 (the hinging method is: hinge shafts are fixedly connected to the upper positions of the front and rear side walls of the aluminum alloy secondary window frame 4. Correspondingly, a hinge seat for hinging the hinge shafts is fixedly connected to the upper end of the right side wall of the outer window frame 1).

[0049] Since the aluminum alloy auxiliary window frame 4-glass plate structure is matched with the sliding window body with a larger size, the aluminum alloy auxiliary window frame 4-glass plate structure is heavy. In order to save effort when flipping and opening (during the flipping and opening process, the arm pulls the aluminum alloy auxiliary window frame 4 upwards, and in this process, the weight of the heavy aluminum alloy auxiliary window frame 4-glass plate needs to be overcome, so it is very strenuous). A spring pull-back assembly 5 is assembled and connected between the upper end of the aluminum alloy auxiliary window frame 4 and the top of the outer window frame 1. The spring pull-back assembly 5 is used to save effort during the flipping and pulling process.

[0050] Specifically, the spring pull-back assembly 5 includes a plurality of curved springs 51 , and two ends of the curved springs 51 are respectively fixedly connected to the top of the outer window frame 1 and the upper end of the aluminum alloy auxiliary window frame 4 .

[0051] At the same time, the spring pullback assembly also includes a support rod 52 that cooperates with the bending spring 51, and the support rod 52 is fixedly connected to the top of the outer window frame 1 (the front and rear ends of the support rod 52 are respectively fixedly connected with a support 521, and the support 521 is fixedly connected to the top right side of the outer window frame 1).

[0052] During the process of flipping and closing the auxiliary soundproof window mechanism (i.e., during the downward flipping process), the bent spring 51 is bent and pulled with the support rod 52 as a fulcrum (during this process, since the gravity of the auxiliary soundproof window mechanism is downward, it is easier to flip downward). However, flipping upward to open requires overcoming gravity, which is more laborious. Therefore, during the downward flipping and closing process, the bent spring 51 is bent and pulled to form a spring restoring force. During the upward flipping and opening process, the restoring force of the bent spring 51 is used to achieve labor-saving opening in the auxiliary state.

[0053] The above method solves the technical defect of poor sound insulation effect of traditional single sliding windows, realizes protection by the glass retaining wall formed by the auxiliary sound insulation window mechanism, and solves the defect of the bulky auxiliary sound insulation window mechanism being difficult to close and open.

[0054] Example 2

[0055] like Figures 1-7 As shown, in this embodiment, based on the structure of embodiment 1, the outer window frame 1 and the aluminum alloy auxiliary window frame 4 are connected via a plurality of elastic buckle structures 3 .

[0056] The elastic buckle lock structure 3 is used to realize that when the aluminum alloy auxiliary window frame 4 is closed, the aluminum alloy auxiliary window frame 4 is not easily blown open by external forces such as wind under the buckle of the elastic buckle lock structure 3, so as to realize safe use.

[0057] Specifically, the elastic buckle locking structure 3 is distributed at the front and rear side positions of the outer window frame 1 and the aluminum alloy auxiliary window frame 4 to achieve synchronous buckling from the front and rear double-layer positions.

[0058] Specifically, the elastic buckle lock structure 3 includes a strip-shaped lock projection 32 installed on the outer side wall of the outer window frame 1, and a bayonet 41 adapted to the strip-shaped lock projection 32 is provided on the aluminum alloy secondary window frame 4. When the aluminum alloy secondary window frame 4 is closed, the strip-shaped lock projection 32 is snapped into the bayonet 41.

[0059] Meanwhile, in order to realize that the strip-shaped lock projection 32 is clamped tightly in the bayonet 41, a number of elastic lock heads 33 are assembled and connected to the front and rear side walls of the strip-shaped lock projection 32.

[0060] The specific structure of the elastic lock head 33 is as follows: the elastic lock head 33 includes a curved lock head portion, and a cylindrical sliding portion is integrally formed on the lock head portion. Correspondingly, a cylindrical groove for slidably connecting the cylindrical sliding portion is provided on the strip-shaped lock projection 32. An inner spring 331 is fixedly connected to the cylindrical sliding portion, and the inner spring 331 is fixedly connected in the cylindrical groove.

[0061] Corresponding to the elastic lock head 33, a curved groove 411 adapted to the lock head portion is provided on the inner side wall of the bayonet 41. When the strip-shaped lock projection 32 is snapped into the bayonet 41, the lock head portion elastically presses against the curved groove 411 (the shape of the curved groove 411 is hemispherical); the lock head portion can slide and fall off along the curved groove 411. Specifically, in order to prevent the elastic lock head 33 from being completely stuck in the curved groove 411, the size of the curved groove 411 is designed to be slightly larger than the lock head portion, so that the lock head portion can be disengaged from the curved groove 411.

[0062] During the process of closing the aluminum alloy secondary window frame 4, as the aluminum alloy secondary window frame 4 approaches the outer window frame 1, at this time, the strip-shaped lock projection 32 is snapped into the bayonet 41. During this process, the lock head portion is elastically compressed until it is snapped into the curved groove 411.

[0063] Embodiment 3

[0064] As Figures 1-7 shown, on the basis of the structure of Embodiment 1 in this embodiment, in order to facilitate the opening of the aluminum alloy secondary window frame 4, a sunk groove 31 adapted to the strip-shaped lock projection 32 is provided on the outer window frame 1. Two ends in the sunk groove 31 are fixedly connected with short columns 321 slidably connected in the strip-shaped lock projection 32 (specifically, inner sliding column grooves for slidably connecting the short columns 321 are provided on the strip-shaped lock projection 32). A small spring 3211 is sleeved on the short column 321, and two ends of the small spring 3211 are respectively fixedly connected to the inner side wall of the strip-shaped lock projection 32 and the bottom of the sunk groove 31.

[0065] During the opening process, the hand presses the strip-shaped lock projection 32, and the strip-shaped lock projection 32 disengages from the bayonet 41 and elastically moves into the sunk groove 31. During the process of pressing the strip-shaped lock projection 32 to disengage from the bayonet 41, the lock head portion retracts into the strip-shaped lock projection 32 and slides and falls off along the curved groove 411.

[0066] Specifically, during the process of pressing the strip lock projection 32 by hand, at this time, the lock head of the curved structure slides relative to the curved groove 411 with a slightly larger relative size until the lock head completely disengages from the curved groove 411.

[0067] After the pressing operation, due to the reset pulling of the bending spring 51 on the upper end of the aluminum alloy secondary window frame 4, the aluminum alloy secondary window frame 4 is slightly flipped to have a certain gap with the outer window frame 1. This method avoids the strip lock projection 32 being re-locked into the bayonet 41 after the hand releases the pressing.

[0068] Through the above method, the aluminum alloy secondary window frame 4 is locked and unlocked with the outer window frame 1 in a simple and easy-to-operate manner, and has high stability after locking and is convenient to unlock, greatly improving its use flexibility.

[0069] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
