Description

Technical Field

[0001] This utility model relates to the field of architectural decoration engineering technology, and in particular to a point support device for building curtain walls. Background Technology

[0002] With the acceleration of urbanization and the continuous improvement of architectural aesthetics, building curtain walls, as an important part of building appearance, must not only meet the requirements of building mechanical performance, but also have good light transmission and visual appeal. At present, most building curtain wall support devices on the market adopt frame structure. Although this structure is stable and reliable, it limits the creative expression of architects to a certain extent and makes it difficult to achieve a light, thin and transparent visual effect. In recent years, point support devices have gradually become one of the hot spots in the market due to their unique advantages. They can not only meet the basic functional requirements of buildings, but also greatly enhance the artistic value of buildings.

[0003] A search revealed Chinese Patent Publication No. CN215519389U, which discloses a building curtain wall support structure, relating to the field of architectural engineering technology. The structure includes a curtain wall support frame. Short rotating shafts are provided on the front surface of the support frame near both ends in the front-rear direction. Each of the two short rotating shafts has a curtain wall suction cup at one end. The front surfaces of the two suction cups have friction surfaces near their four edges, and elastic pressure rings are provided on the circumferential edges of the friction surfaces on the front surfaces of the two suction cups. This invention, by removing air from the glass curtain wall and its contact points, allows the glass curtain wall to be firmly adhered to the device under atmospheric pressure. This eliminates the need for any modifications to the glass curtain wall's perimeter without compromising its stability and safety, increasing the practicality and overall aesthetics of the installation. However, in actual use, the device connects the curtain wall via four fixed suction cups, resulting in a relatively concentrated fixing position. This fails to effectively distribute the negative pressure, thus reducing stability during fixing. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a point support device for building curtain walls, which aims to improve the problem that the fixed positions are relatively concentrated in the existing technology, which cannot effectively distribute the negative pressure position and thus reduce the stability during fixing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a point support device for building curtain walls, comprising a frame, wherein limiting shells are fixedly connected to the left and right ends of the rear side of the inner wall of the frame, a threaded rod is rotatably connected to the inner wall of the limiting shell, a knob is fixedly connected to one end of the threaded rod, a displacement plate is threadedly connected to the outer wall of the threaded rod, a positioning plate is fixedly connected to the front side of the displacement plate, a fixing plate is fixedly connected to the top of the positioning plate, an electric push rod is rotatably connected to the front side of the fixing plate, a negative pressure fan is rotatably connected to the front side of the electric push rod, an exhaust valve is connected to the top wall of the negative pressure fan, a rubber ring is fixedly connected to the front side of the negative pressure fan, the bottom wall of the negative pressure fan is rotatably connected to the front side of the positioning plate, and a fixing mechanism is provided at the bottom front side of the positioning plate.

[0006] The above technical solution allows the displacement plate to slide on the front side of the limiting shell under the rotation of the threaded rod, thereby driving the negative pressure fan to adjust the horizontal position. At the same time, under the drive of the electric push rod, the deflection angle of the connected curtain wall is changed, which improves the flexibility of the curtain wall connection and ensures the stability of the connection.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes two connecting plates, the rear sides of which are fixedly connected to the front side of the bottom wall of the positioning plate. A swing cylinder is fixedly connected to one side of the connecting plate, a rotating shell is fixedly connected to one end of the swing cylinder, a connecting rod is fixedly connected to the bottom wall of the rotating shell, and a fixing shell is fixedly connected to the bottom end of the connecting rod. Multiple locking slots are fixedly connected at equal intervals to the bottom wall of the frame, and the top rear side of the fixing shell engages with the corresponding locking slot.

[0009] The above technical solution enables the rotating shell to rotate when the swing cylinder is activated, causing the connecting rod to rotate and the fixed shell to swing upward, thereby achieving the effect of engaging and fixing with the corresponding locking groove, thus completing the purpose of fixing the position of the positioning plate and reducing the possibility of slippage between the displacement plate and the positioning plate during use.

[0010] As a further description of the above technical solution:

[0011] The fixing mechanism also includes two rubber pads, the bottoms of which are fixedly connected to the front side of the top wall of the fixing shell.

[0012] The above technical solution reduces damage to the bottom of the frame caused by the fixed shell, thanks to the connection of the rubber pad.

[0013] As a further description of the above technical solution:

[0014] A control switch is fixedly connected to the rear left end of the inner wall of the frame. The control switch is electrically connected to the electric push rod, the negative pressure fan and the swing cylinder respectively.

[0015] The above technical solution enables the control switch to open and close the equipment by being electrically connected to the electric push rod, the negative pressure fan, and the swing cylinder respectively.

[0016] As a further description of the above technical solution:

[0017] A sealing ring is fixedly installed at the bottom of the outer wall of the exhaust valve, and the outer wall of the sealing ring is fixedly connected to the top wall of the negative pressure fan.

[0018] The above technical solution improves the sealing performance between the exhaust valve and the top of the negative pressure fan by connecting the sealing ring.

[0019] As a further description of the above technical solution:

[0020] Multiple rubber strips are fixedly connected to the outer walls of both knobs, and the multiple rubber strips are arranged in an equidistant ring.

[0021] The above technical solution increases the anti-slip effect on the knob by connecting multiple rubber strips.

[0022] As a further description of the above technical solution:

[0023] A square groove is provided on the rear side of the inner wall of the frame, and a slide rail is fixedly connected to the middle of the front side of the frame.

[0024] The above technical solution reduces damage to the frame when the positioning plate slides, thanks to the connection of the slide rail.

[0025] As a further description of the above technical solution:

[0026] The frame is fixedly connected to four corners on the rear side, and the front side of the connecting seat is provided with an installation groove.

[0027] The above technical solution facilitates the installation and fixation of the device by connecting the connector and the mounting slot.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the rotation of the threaded rod causes the displacement plate to slide on the front side of the limiting shell, thereby driving the positioning plate to move and changing the horizontal position of the negative pressure fan. At the same time, under the drive of the electric push rod, the negative pressure fan rotates around the positioning plate connected to the bottom as an axis, thereby changing the connection angle and avoiding the situation where the negative pressure position cannot be well dispersed, thus improving the stability when fixed.

[0030] 2. In this utility model, by starting the swing cylinder, one end of it drives the rotating shell to rotate, and then, under the connection of the connecting rod, the fixed shell swings upward, so as to complete the locking and fixing of the corresponding locking groove, thereby achieving the purpose of fixing the position of the positioning plate and reducing the possibility of the displacement plate sliding during use.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a point support device for building curtain walls, comprising a frame 1. Limiting shells 3 are fixedly connected to the left and right ends of the rear side of the inner wall of the frame 1. A threaded rod 4 is rotatably connected to the inner wall of the limiting shell 3. A knob 5 is fixedly connected to one end of the threaded rod 4, so that rotating the knob 5 drives the threaded rod 4 to rotate, thereby driving a displacement plate 6. The displacement plate 6 is threadedly connected to the outer wall of the threaded rod 4. A positioning plate 7 is fixedly connected to the front side of the displacement plate 6. A fixing plate 8 is fixedly connected to the top of the positioning plate 7, so that the positioning plate 7 drives the positioning plate 8 into position. The horizontal displacement changes the horizontal position of the negative pressure fan 10, which facilitates the dispersion of negative pressure stress and improves the fixing effect. The front side of the fixing plate 8 is rotatably connected to the electric push rod 9, and the front side of the electric push rod 9 is rotatably connected to the negative pressure fan 10. The top wall of the negative pressure fan 10 is connected to the exhaust valve 11, and the front side of the negative pressure fan 10 is fixedly connected to the rubber ring 13. With the connection of the electric push rod 9, the angle of the negative pressure fan 10 can be adjusted. The bottom wall of the negative pressure fan 10 is rotatably connected to the front side of the positioning plate 7, and the bottom front side of the positioning plate 7 is provided with a fixing mechanism 2.

[0040] Specifically, by rotating the threaded rod 4, the displacement plate 6 will move as the threaded rod 4 rotates under the constraint of the limiting shell 3. This causes the displacement plate 6 to slide on the front side of the limiting shell 3, thereby moving the positioning plate 7 together. This allows the horizontal position of the negative pressure fan 10 to be adjusted. By activating the electric push rod 9, the negative pressure fan 10 can rotate around the positioning plate 7 connected at the bottom, thereby changing the connection angle between the negative pressure fan 10 and the curtain wall. In this way, a negative pressure connection is formed between the negative pressure fan 10 and the curtain wall, effectively avoiding the problem of uneven distribution of negative pressure. This improves the stability of the negative pressure fan 10 when it is fixed and ensures its high efficiency during operation.

[0041] Reference Figure 1 , Figure 3 and Figure 5The fixing mechanism 2 includes two connecting plates 201. The rear sides of the two connecting plates 201 are fixedly connected to the front side of the bottom wall of the positioning plate 7. A swing cylinder 202 is fixedly connected to one side of the connecting plate 201, so that when the swing cylinder 202 is activated, the rotating shell 203 fixed at one end of it completes the rotation. The rotating shell 203 is fixedly connected to one end of the swing cylinder 202. A connecting rod 204 is fixedly connected to the bottom wall of the rotating shell 203. Then, under the connection of the connecting rod 204, the fixing shell 205 rotates synchronously. The bottom end of the connecting rod 204 is fixedly connected to the fixing shell 205. Multiple locking grooves 206 are fixedly connected at equal intervals on the bottom wall of the frame 1. Under the swing of the fixing shell 205, it completes the locking with the locking groove 206, thereby fixing the position of the positioning plate 7. The top rear side of the fixing shell 205 engages with the corresponding locking groove 206.

[0042] Specifically, by activating the swing cylinder 202, the drive housing 203 is rotated. Driven by the swing cylinder 202, the housing 203 drives the connecting rod 204 to rotate. As the connecting rod 204 rotates, the fixed housing 205 fixed on the connecting rod 204 swings upward, eventually allowing the fixed housing 205 to engage and lock with the corresponding locking groove 206, thus fixing the position of the positioning plate 7. During use, the slippage between the displacement plate 6 and the positioning plate 7 is effectively reduced, thereby improving the stability of the device.

[0043] Reference Figure 1 , Figure 4 and Figure 5 The fixing mechanism 2 also includes two rubber pads 207, the bottoms of which are fixedly connected to the front side of the top wall of the fixing shell 205; a control switch 15 is fixedly connected to the left end of the rear side of the inner wall of the frame 1, and the control switch 15 is electrically connected to the electric push rod 9, the negative pressure fan 10 and the swing cylinder 202 respectively; a square groove 18 is opened on the rear side of the inner wall of the frame 1, and a slide rail 19 is fixedly connected to the middle of the front side of the frame 1;

[0044] Specifically, the rubber pad 207 reduces wear on the bottom of the frame 1 caused by the fixed shell 205. The control switch 15, which is electrically connected to the electric push rod 9, the negative pressure fan 10 and the swing cylinder 202 respectively, enables the device to be turned on and off. The slide rail 19 provides sliding support for the positioning plate 7, thereby reducing damage to the frame 1 caused by the positioning plate 7.

[0045] Reference Figure 1 and Figure 3A sealing ring 12 is fixedly installed on the bottom of the outer wall of the exhaust valve 11, and the outer wall of the sealing ring 12 is fixedly connected to the top wall of the negative pressure fan 10; multiple rubber strips 14 are fixedly connected to the outer walls of the two knobs 5, and the multiple rubber strips 14 are arranged in an equidistant ring; a connecting seat 16 is fixedly connected to the four corners of the rear side of the frame 1, and an installation groove 17 is opened on the front side of the connecting seat 16.

[0046] Specifically, the sealing ring 12 improves the sealing effect between the exhaust valve 11 and the top of the negative pressure fan 10, the fixing of multiple rubber strips 14 improves the anti-slip effect of the knob 5 during use, and the connecting seat 16 and the mounting groove 17 facilitate the fixing and installation of the device.

[0047] Working principle: When the curtain wall is initially fixed, the threaded rod 4 is rotated, causing the displacement plate 6 to move under the restriction of the limiting shell 3. This allows the displacement plate 6 to slide in front of the limiting shell 3, thereby moving the positioning plate 7 and changing the horizontal position of the negative pressure fan 10. Simultaneously, the electric push rod 9 is activated, causing the negative pressure fan 10 to rotate around the positioning plate 7 at its bottom, thus changing the angle at which the negative pressure fan 10 connects to the curtain wall. This establishes a negative pressure connection between the negative pressure fan 10 and the curtain wall, preventing the inability to effectively distribute the negative pressure and improving the stability during fixing. Furthermore, the swing cylinder 202 is activated, causing one end to drive the rotating shell 203 to rotate. This rotates the connecting rod 204, causing the fixing shell 205, which is fixed by the connecting rod 204, to swing upwards, thus engaging and locking with the corresponding locking groove 206. This fixes the position of the positioning plate 7 and reduces the possibility of slippage between the displacement plate 6 and the positioning plate 7 during use.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
