Description

Technical Field

[0001] This invention relates to the field of curtain wall technology, specifically to a curtain wall adapter. Background Technology

[0002] A curtain wall is a type of exterior wall covering a building. Curtain walls are generally non-load-bearing and resemble a hanging curtain, also known as a suspended curtain. They are lightweight walls suspended outside the main structure. Curtain walls are characterized by good decorative effect, light weight, and fast installation speed. They are an ideal type of lightweight and prefabricated exterior wall, and are therefore widely used in modern large and high-rise buildings. When connecting them, adapters are required.

[0003] However, existing adapters still have the following technical drawbacks: 1. When using it, it is inconvenient to adjust the angle of the interconnection, which affects the effect of the material. 2. When in use, the two adjacent curtain walls are fixed with traditional bolts, which makes them susceptible to corrosion from rainwater during installation, causing the connection to loosen.

[0004] Based on this, this solution proposes a curtain wall adapter. Summary of the Invention

[0005] The purpose of this invention is to provide a curtain wall adapter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a curtain wall adapter, comprising a first curtain wall and a second curtain wall. The first curtain wall and the second curtain wall are respectively provided with a first mounting groove and a second mounting groove on the side that are close to each other. A round rod and a screw rod are rotatably installed in the second mounting groove. A linkage gear and two connecting rods are fixedly sleeved on the round rod. The same connecting block located in the first mounting groove is fixedly installed on the two connecting rods. Both sides of the connecting block have through holes, and two central rods are rotatably installed on the bottom inner wall of the connecting block. Metal rods are movably installed in the two through holes. Movable plates and limiting blocks are fixedly installed at both ends of the two metal rods, respectively. Worm gears and extrusion discs are fixedly sleeved on the two central rods. A worm gear that meshes with the two worm gears is rotatably installed inside the connecting block. The inner walls on both sides of the first mounting groove are provided with limiting grooves that are adapted to the limiting block; The lead screw is threaded with a lead screw guide sleeve, and a knob is fixedly sleeved on the top of the lead screw. A linkage rack that meshes with the linkage gear is fixedly installed on the lead screw guide sleeve.

[0007] Preferably, a knob is fixedly sleeved at one end of the worm gear.

[0008] Using the above technical solution, the worm gear can be easily rotated via a knob.

[0009] Preferably, a limiting gear is fixedly sleeved on the lead screw, and two fixing blocks are fixedly installed on the top of the second curtain wall. Each fixing block has a movable hole, and a movable rod is movably installed in each of the two movable holes. A limiting rack is fixedly installed at the end of each of the two movable rods that is close to each other. A toggle block is fixedly installed on the top of each of the two limiting racks. A first spring is sleeved on each of the two movable rods. One end of each of the two first springs is fixed to the inner wall of the corresponding movable hole, and the other end of each of the two first springs is fixed to the corresponding movable rod.

[0010] By adopting the above technical solution, by first moving the two actuating blocks outward to move the two limiting racks apart, the two limiting racks are no longer engaged with the limiting gear, thus ceasing to limit the rotation of the limiting gear and the lead screw. Then, by releasing the two actuating blocks, the two limiting racks are reset by the action of the first spring, allowing the two limiting racks to re-engage with the limiting gear, thereby re-limiting the rotation of the limiting gear and the lead screw, and thus fixing the rotation angle of the first curtain wall.

[0011] Preferably, a slide rail is fixedly installed in the second mounting groove, and a slider is slidably installed on the slide rail, with the slider being fixedly connected to the lead screw guide sleeve.

[0012] The above technical solution facilitates the movement of the lead screw guide sleeve through the slide rail and slider.

[0013] Preferably, the two center rods are located at the eccentricity of the corresponding extrusion discs.

[0014] Preferably, a second spring is fitted onto each of the two metal rods, with one end of the two second springs fixed to the corresponding metal rod and the other end fixed to the inner wall of the corresponding through hole.

[0015] By adopting the above technical solution, the second spring facilitates the reset of the metal rod.

[0016] A curtain wall adapter includes the following usage steps: Step S1: In use, first insert the connecting block into the first mounting slot, then rotate the knob to drive the worm gear to rotate. The worm gear drives the two worm wheels to rotate, which in turn drives the two center rods to rotate, which in turn drives the two extrusion discs to rotate. The two extrusion discs extrude the corresponding movable plates, which causes the two movable plates to move apart, which in turn causes the two limit blocks to move apart, so that the two limit blocks are inserted into the corresponding limit slots. This indirectly fixes the connecting block to the first curtain wall and indirectly fixes the second curtain wall to the first curtain wall. Step S2: In order to adjust the angle between the first curtain wall and the second curtain wall, the two toggle blocks can be moved outward to move the two limiting racks apart, so that the two limiting racks are no longer engaged with the limiting gears, and the limiting gears and lead screws are no longer limited to rotation. Step S3: Then, turn the knob to drive the lead screw to rotate. The lead screw drives the lead screw guide sleeve to move vertically, which in turn drives the linkage rack to move vertically. The linkage rack drives the linkage gear and the round rod to rotate, which in turn drives the two connecting rods to rotate, which in turn drives the connecting block and the first curtain wall to rotate, thus adjusting the angle between the first curtain wall and the second curtain wall. Step S4: Then, by releasing the two actuating blocks, the two limiting racks are reset by the action of the first spring, so that the two limiting racks re-engage with the limiting gear, thereby re-rotating and limiting the limiting gear and the lead screw, thus fixing the rotation angle of the first curtain wall.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In use, the connecting block is first inserted into the first mounting groove, and then the worm gear is rotated by rotating the knob. The worm gear drives the two worm wheels to rotate, which in turn drives the two central rods to rotate, which in turn drives the two extrusion discs to rotate. The two extrusion discs respectively extrude the corresponding movable plates, which causes the two movable plates to move apart, which in turn causes the two limiting blocks to move apart, so that the two limiting blocks are respectively inserted into the corresponding limiting grooves. This indirectly fixes the connecting block to the first curtain wall. In order to adjust the angle between the first curtain wall and the second curtain wall, the two actuating blocks can be moved outward to drive the two limiting racks. The separation and movement of the two limiting racks prevents them from meshing with the limiting gear, thus ceasing the rotational limitation on the limiting gear and the lead screw. Turning the knob then rotates the lead screw, which in turn moves the lead screw guide sleeve vertically, causing the linkage rack to move vertically. The linkage rack then rotates the linkage gear and the round rod, which in turn rotates the two connecting rods, thus rotating the connecting block and the first curtain wall. This allows adjustment of the angle between the first and second curtain walls. Releasing the two toggle blocks resets the two limiting racks under the action of the first spring, causing them to re-mesh with the limiting gear. This re-limits the rotation of the limiting gear and the lead screw, fixing the rotation angle of the first curtain wall. This invention has a simple structure and is easy to use. The curtain wall adapter described herein facilitates adjustment according to the angle of connection between the two curtain walls, and the rotating locking structure facilitates quick installation and connection between the two curtain walls, saving time and effort.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-5This invention provides a technical solution: a curtain wall adapter, comprising a first curtain wall 1 and a second curtain wall 4. A first mounting groove 2 and a second mounting groove 19 are respectively provided on the sides of the first curtain wall 1 and the second curtain wall 4 that are close to each other. A round rod 16 and a lead screw 13 are rotatably mounted in the second mounting groove 19. A linkage gear 18 and two connecting rods 17 are fixedly sleeved on the round rod 16. A connecting block 3 located in the first mounting groove 2 is fixedly mounted on the two connecting rods 17. Through holes are provided on both sides of the connecting block 3, and two central rods 25 are rotatably mounted on the bottom inner wall of the connecting block 3. Metal rods 28 are movably mounted in both through holes. Movable plates 23 and limiting blocks 22 are fixedly mounted at both ends of the two metal rods 28, respectively. Second springs 11 are sleeved on both metal rods 28, with one end of each second spring 11 fixed to the corresponding metal rod 28 and the other end fixed to the inner wall of the corresponding through hole. Worm gears 26 and extrusion discs 27 are fixedly sleeved on both central rods 25. Two central rods 25 are located eccentrically on the corresponding extrusion discs 27. A worm 24, meshing with two worm gears 26, is rotatably installed inside the connecting block 3. Limiting grooves 21, adapted to the limiting blocks 22, are provided on the inner walls of both sides of the first mounting groove 2. A knob 20 is fixedly sleeved on one end of the worm 24. With the above structure, the connecting block 3 is first inserted into the first mounting groove 2. Then, by rotating the knob 20, the worm 24 is rotated. The worm 24 drives the two worm gears 26 to rotate, which in turn drives the two central rods 25 to rotate, which in turn drives the two extrusion discs 27 to rotate. The two extrusion discs 27 respectively extrude the corresponding movable plates 23, which causes the two movable plates 23 to move apart, which in turn causes the two limiting blocks 22 to move apart, so that the two limiting blocks 22 are respectively inserted into the corresponding limiting grooves 21. This indirectly fixes the connecting block 3 to the first curtain wall 1, and indirectly fixes the 4 to the first curtain wall 1.

[0022] Combination Figure 1-5As shown, a screw guide sleeve 14 is threaded onto the screw 13, and a knob 5 is fixedly fitted onto the top of the screw 13. A linkage rack 15 that meshes with the linkage gear 18 is fixedly installed on the screw guide sleeve 14. A slide rail is fixedly installed in the second mounting groove 19, and a slider is slidably installed on the slide rail. The slider is fixedly connected to the screw guide sleeve 14. Two fixing blocks 8 are fixedly installed on the top of the second curtain wall 4. Each fixing block 8 has a movable hole, and a movable rod 9 is movably installed in each of the two movable holes. A limit rack 10 is fixedly installed at the end of each of the two movable rods 9 that is close to each other. A toggle block 7 is fixedly installed on the top of each of the two limit racks 10. A first spring 12 is fitted onto each of the two movable rods 9. One end of each of the two first springs 12 is fixed to the inner wall of the corresponding movable hole, and the other end of each of the two first springs 12 is fixed to the corresponding movable rod 9. With the above structure, in order to adjust the angle between the first curtain wall 1 and the second curtain wall 4, it is possible to first... The two toggle blocks 7 are moved apart, causing the two limiting racks 10 to move separately. This prevents the two limiting racks 10 from meshing with the limiting gear 6, thus ceasing to limit the rotation of the limiting gear 6 and the lead screw 13. Then, turning the knob 5 causes the lead screw 13 to rotate, which in turn causes the lead screw guide sleeve 14 to move vertically. This causes the linkage rack 15 to move vertically, which in turn causes the linkage gear 18 and the round rod 16 to rotate. This causes the two connecting rods 17 to rotate, which in turn causes the connecting block 3 and the first curtain wall 1 to rotate. This allows the angle between the first curtain wall 1 and the second curtain wall 4 to be adjusted. Then, by releasing the two toggle blocks 7, the two limiting racks 10 are reset by the action of the first spring 12, causing the two limiting racks 10 to mesh with the limiting gear 6 again. This re-limits the rotation of the limiting gear 6 and the lead screw 13, thus fixing the rotation angle of the first curtain wall 1.

[0023] In this invention, during use, the connecting block 3 is first inserted into the first mounting groove 2. Then, by rotating the knob 20, the worm gear 24 is rotated. The worm gear 24 drives the two worm wheels 26 to rotate, which in turn drives the two center rods 25 to rotate, and thus drives the two extrusion discs 27 to rotate. The two extrusion discs 27 respectively extrude the corresponding movable plates 23, which causes the two movable plates 23 to move apart, thereby causing the two limiting blocks 22 to move apart, so that the two limiting blocks 22 are respectively inserted into the corresponding limiting grooves 21. This indirectly fixes the connecting block 3 to the first curtain wall 1 and indirectly fixes the second curtain wall 4 to the first curtain wall 1. To adjust the angle between the first curtain wall 1 and the second curtain wall 4, the two actuating blocks 7 can be moved outward to move the two limiting racks 10 apart. This allows the two limiting racks 10 to no longer mesh with the limiting gear 6, thus ceasing the rotational limitation of the limiting gear 6 and the lead screw 13. Then, rotating the knob 5 drives the lead screw 13 to rotate, which in turn drives the vertical movement of the lead screw guide sleeve 14, thereby driving the vertical movement of the linkage rack 15. The linkage rack 15 drives the rotation of the linkage gear 18 and the round rod 16, which in turn drives the rotation of the two connecting rods 17, and thus the rotation of the connecting block 3 and the first curtain wall 1. This allows the angle between the first curtain wall 1 and the second curtain wall 4 to be adjusted. Then, by releasing the two toggle blocks 7, the two limiting racks 10 are reset by the action of the first spring 12, causing the two limiting racks 10 to re-mesh with the limiting gear 6, thus re-limiting the rotation of the limiting gear 6 and the lead screw 13, and fixing the rotation angle of the first curtain wall 1. The present invention has a simple structure and is easy to use. The curtain wall adapter is easy to adjust according to the angle of mutual connection, and the rotating locking structure facilitates quick installation and connection between two curtain walls, saving time and effort.
