Description

Technical Field

[0001] The utility model relates to the technical field of building curtain walls, and particularly relates to a folding hinge structure for an electric opening window for fire smoke exhaust. Background Art

[0002] Electric smoke exhaust adopts an electric opening window with an upper smoke exhaust structure, which is automatically opened by detecting a fire signal. According to the specific requirements of the smoke exhaust volume, generally, the opening angle of an electric opening window for fire smoke exhaust is not less than 70°. For an ordinary electric opening window, a sliding support hinge needs to be used as an opening angle control device, so that the setting of this device can only make the opening angle of the electric opening window reach 30° or the opening distance is less than 800 mm, and this angle or opening distance far from meets the requirements of fire smoke exhaust.

[0003] In the prior art, such as the invention patent with the patent number CN 109162550 B, an electric smoke exhaust opening window folding hinge device is disclosed, which effectively increases the hinge opening angle to meet the fire opening requirements. However, in the above prior art, the upper hinge piece is fixedly connected to the installation beam through a first installation piece. In fact, the first installation piece is a window frame. Therefore, the first installation piece can only be located below the installation beam and inside the window opening. If the upper hinge wants to be connected to the window frame, additional bending is required, so that the upper hinge is a Z-shaped with two bends. However, in the actual use process, the direct fixing method of the upper hinge to the window frame has the following disadvantages:

[0004] (1) The window frame is usually a hollow profile, directly used as a fixing base, and the fixing relationship is unreliable, with a risk of falling off.

[0005] (2) The second upper hinge plate of the upper hinge is fixed to the lower surface of the window frame, directly exposed at the window, and is easily affected by the external environment and rusts and loosens, etc. Moreover, the screws are vertically fixed, which easily causes the screws to fall off and the appearance is poor.

[0006] In summary, the above prior art has problems that the fixing base of fixing the upper hinge on the window frame is unreliable and there is a risk of loosening and falling off.

[0007] Based on this, it is necessary to study a folding hinge structure for an electric opening window for fire smoke exhaust. Content of the Utility Model

[0008] In view of this, the purpose of the utility model is to provide a folding hinge structure for an electric opening window for fire smoke exhaust, which can effectively solve the problems that the fixing base of fixing the upper hinge on the window frame in the prior art is unreliable and there is a risk of loosening and falling off.

[0009] To achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A folding hinge structure for an electric opening window for fire smoke exhaust, characterized in that it includes an upper hinge, a lower hinge, a mounting beam, a window frame, a window sash frame and an opening window glass;

[0011] Both the upper hinge and the lower hinge are integrally bent parts;

[0012] The upper hinge is L-shaped and includes an upper fixing plate and an upper hinge plate that are vertically connected. The upper fixing plate is fixedly connected to the outer end face of the mounting beam;

[0013] The lower hinge is Z-shaped and includes a lower fixing plate, a middle connecting plate and a lower hinge plate. The lower fixing plate is fixedly connected to the window sash frame, and an opening window glass is arranged inside the window sash frame;

[0014] Both ends of the middle connecting plate are vertically connected to one end of the lower fixing plate and one end of the lower hinge plate respectively, and the other end of the lower hinge plate is hingedly connected to one end of the upper hinge plate;

[0015] Both the middle of the lower hinge plate and the middle of the middle connecting plate are provided with avoidance areas adapted to the shape of the upper hinge. When the opening window is closed, the lower end faces of the upper hinge plate and the lower fixing plate are on the same plane;

[0016] The window frame is fixed to the lower end face of the mounting beam, and an electric window opener is arranged between the window frame and the window sash frame.

[0017] Further, an attached beam is fixedly connected to the outer end face of the mounting beam. The attached beam is parallel to the mounting beam and extends along the length direction of the mounting beam, and the upper fixing plate is vertically fixed on the outer end face of the attached beam.

[0018] Further, a curtain wall glass is vertically fixedly connected to the outer end face of the mounting beam. The curtain wall glass is located above the attached beam and the upper fixing plate;

[0019] A sealing strip extending in the front-rear direction is installed between the curtain wall glass and the upper hinge plate.

[0020] Further, the sealing strip includes a connecting plate and a sealing plate;

[0021] One end of the connecting plate is fixedly connected to the outer end face of the mounting beam, and the upper surface of the connecting plate is fixedly connected to the lower surface of the curtain wall glass;

[0022] The sealing plate is U-shaped with an inward opening. One end of the sealing plate is fixedly connected to the other end of the connecting plate, and the other end of the sealing plate is fixed on the attached beam.

[0028] The beneficial effects of the above technical solution are as follows:

[0029] The present utility model adopts an L-shaped upper hinge, and directly fixedly connects the upper fixing plate of the upper hinge to the outer end face of the installation beam instead of fixing it on the window frame. The fixing relationship is more reliable; at the same time, it is realized that the upper fixing plate is not located on the lower surface of the window frame, avoiding the fixing node of the upper fixing plate being exposed in the window range. This can not only improve the aesthetic degree of the window frame but also avoid the fixing connection of the upper fixing plate being directly exposed to the external environment and being less likely to be corroded and loosened by the external environment; in addition, the upper fixing plate is fixed from the side by screws instead of from bottom to top, which can further prevent it from falling off after loosening.

[0030] To sum up, on the premise of maintaining the advantage of a large flipping angle range of the existing technology, the present utility model solves the problems in the existing technology that the upper hinge is fixed on the window frame with an unreliable fixing foundation and a risk of loosening and falling off, improves the reliability of the fixing foundation of the upper hinge, and improves the safety.

Detailed Implementation Manner

[0036] The present utility model will be further described in detail below in conjunction with the accompanying drawings and the specific implementation manner:

[0037] This embodiment aims to provide a folding hinge structure for an electric opening window for fire smoke exhaust, which is mainly used for the installation of an electric opening window for fire smoke exhaust, aiming to solve the problems in the prior art that the upper hinge 1 is fixed on the window frame 4 with an unreliable fixing foundation and a risk of loosening and falling off.

[0038] A folding hinge structure for an electric opening window for fire smoke exhaust, as Figure 2 and Figure 3 , includes an upper hinge 1, a lower hinge 2, an installation beam 3, a window frame 4, a window sash frame 5, and an opening window glass 6.

[0039] As Figure 1 , both the upper hinge 1 and the lower hinge 2 are integrally bent parts; the upper hinge 1 is L-shaped, including a vertically connected upper fixing plate 101 and an upper hinge plate 102. The upper fixing plate 101 is fixedly connected to the outer end face of the installation beam 3 by screws, and the screws are inserted and fixed from left to right. Compared with the existing installation method from bottom to top, the risk of screw detachment can be reduced. In this application, referring to Figure 2 , the outward direction is the direction towards the outside of the room, that is, Figure 2 the right direction in

[0040] The lower hinge 2 is Z-shaped and bent twice, including a lower fixing plate 201, a middle connecting plate 202, and a lower hinge plate 203. The lower fixing plate 201 is fixedly connected to the window sash frame 5, and an opening window glass 6 is installed in the window sash frame 5; both ends of the middle connecting plate 202 are vertically connected to one end of the lower fixing plate 201 and one end of the lower hinge plate 203 respectively; the other end of the lower hinge plate 203 is hingedly connected to one end of the upper hinge plate 102 by a rotating shaft, thus forming a hinge structure. Avoidance areas 204 adapted to the shape of the upper hinge 1 are provided in the middle of the lower hinge plate 203 and the middle of the middle connecting plate 202; as Figure 2 , when the opening window is closed, the lower end faces of the upper hinge plate 102 and the lower fixing plate 201 are on the same plane, and the window sash frame 5 is within the range of the window frame 4.

[0041] The window frame 4 is fixed to the lower end face of the installation beam 3, as Figure 4, an electric window opener 13 is provided between the window frame 4 and the sash frame 5. The electric window opener 13 is mainly used to automatically open the opening window when a smoke alarm is triggered. It can be a push rod structure, etc. Its specific structure is prior art. In this embodiment, an electric chain window opener is adopted, which has remarkable features such as large pushing and pulling force and low noise. It can be installed parallel to and closely against the window frame 4, with good concealment and no space occupation. The electric chain window opener is specifically a ZJ-KC02 type fire electric device, mainly composed of a gearbox and a DC motor. The forward and reverse rotation of the motor is realized by changing the polarity of the DC voltage, so that the chain completes the telescopic function. Due to the adoption of an electronic overcurrent protection circuit and a limit switch, the stability of the performance and the smooth operation of the motor are guaranteed to the greatest extent. The specific structure of the electric chain window opener is prior art and will not be elaborated here.

[0042] Considering that the upper fixing plate 101 usually keeps a certain distance from the outer end face of the mounting beam 3, and if the upper fixing plate 101 is too long, it will cause a large moment and be prone to bending, and in this case, it cannot always be ensured that the upper fixing plate 101 can always be just fixed corresponding to the outer end face of the mounting beam 3. For this reason, an auxiliary beam 7 is full-welded and connected to the outer end face of the mounting beam 3. The auxiliary beam 7 is parallel to the mounting beam 3 and extends along the length direction of the mounting beam 3; the upper fixing plate 101 is vertically fixed on the outer end face of the auxiliary beam 7, so as to form a reliable connection with the mounting beam 3 and improve the flexibility of installation.

[0043] Considering that the upper hinge 1 is L-shaped, the vertical upper mounting plate will occupy a certain space on the outer end face of the mounting beam 3, and a curtain wall glass 8 is vertically fixedly connected to the outer end face of the mounting beam 3. The curtain wall glass 8 is located above the auxiliary beam 7 and the upper fixing plate 101. At this time, there is a large gap between the curtain wall glass 8 and the upper hinge plate 102. In order to block this gap and improve the aesthetics, as Figure 2 , a sealing strip 9 extending in the front-rear direction is installed between the curtain wall glass 8 and the upper hinge plate 102.

[0044] The sealing strip 9 includes a connecting plate 901 and a sealing plate 902; the connecting plate 901 is L-shaped, one end of the connecting plate 901 is fixedly connected to the outer end face of the mounting beam 3, and the upper surface of the connecting plate 901 is fixedly connected to the lower surface of the curtain wall glass 8; the sealing plate 902 is U-shaped with an inward opening, one end of the sealing plate 902 is fixedly connected to the other end of the connecting plate 901, and the other end of the sealing plate 902 is fixed on the auxiliary beam 7. The sealing plate 902 is of a through length. Correspondingly, an avoidance hole for the upper fixing plate 101 to pass through is opened on the sealing plate 902 to facilitate the installation of the upper hinge 1. During actual installation, before installing the curtain wall glass 8, first fix the connecting plate 901 on the mounting beam 3, and then install the upper hinge 1; after installing the curtain wall glass 8, install the sealing plate 902 and fix the sealing plate 902 and the curtain wall glass 8 with filling glue.

[0045] To prevent vibration from being transmitted to the opening window glass 6, as Figure 2 and Figure 3 , there is a gap between the upper surface of the opening window glass 6 and the middle connecting plate 202 to avoid direct contact. Specifically, a sash profile 10 is provided on the upper end surface of the sash frame 5; a shock-absorbing strip 12 is provided on the inner end surface of the sash profile 10, and a sash profile edge 11 is provided on the outer end surface of the sash profile 10. The sash profile edge 11 is fixedly connected to the upper surface of the opening window glass 6 and has a gap with the middle connecting plate 202 to prevent vibration from being transmitted to the opening window glass 6. Since both the sash profile 10 and the shock-absorbing strip 12 are of full length, the sash profile 10 and the shock-absorbing strip 12 both extend in the front-rear direction and are provided with avoidance grooves for the middle connecting plate 202 to pass through, so as to facilitate the installation of the lower hinge 2. When the opening window is closed, the shock-absorbing strip 12 is in contact with the outer end surface of the window frame 4 to form a shock-absorbing and buffering effect.
