Description

Technical Field

[0001] The invention belongs to the technical field of building exterior wall decoration, and particularly relates to an aluminum single plate for building exterior walls. Background Art

[0002] Exterior building decoration refers to the decoration and protection of a building's facade, including the application of materials such as paint, tiles, and aluminum veneer. Aluminum veneer is a commonly used exterior wall decoration material, popular for its light weight, high strength, corrosion resistance, and ease of processing and installation. When using aluminum veneer, it is first formed according to the design requirements and then fixed to the building's exterior wall using brackets or fixings, creating an aesthetically pleasing and durable appearance while also providing insulation and sound insulation. Overall, the use of aluminum veneer not only enhances the building's aesthetics but also enhances its functionality and durability.

[0003] The Chinese patent application number 202410955190.6 discloses a brushed aluminum veneer, comprising an aluminum veneer frame, wherein the top of the aluminum veneer frame is provided with a reinforcement component, and the two sides of the aluminum veneer frame are provided with hanging ears, and the tops of the hanging ears are movably installed with a closing component. The present invention uses a reinforcement frame and an elastic airbag so that a certain amount of inert gas is filled in the reinforcement frame and the elastic airbag. The high-pressure environment under the inert filling is utilized, and at the same time, the inert gas with a low thermal conductivity is used to achieve thermal insulation reinforcement inside the aluminum veneer frame. In combination with the polyurethane foam and mineral wool in the filling layer, the brushed aluminum plate is isolated from heat on both the inside and outside during installation and use on the building wall. It has a better thermal insulation effect in cold winter climates and effectively avoids heat loss. At the same time, in hot summer environments, it enhances the insulation against external heat and reduces the impact of external environmental heat on the interior. The comprehensive thermal insulation capacity is greatly improved, and the use effect is good.

[0004] When installing aluminum veneers, the outer fixing frame of the aluminum veneer is usually inserted into the gap and then fixed to the bracket of the outer wall by bolts. Although this method is more beautiful and can make the gap between adjacent aluminum veneers smaller, if a single aluminum veneer is damaged, it is impossible to quickly remove and fix the damaged aluminum veneer, which makes subsequent maintenance inconvenient; at the same time, if a single bolt fixation becomes loose, it will cause the aluminum veneer to fall off, causing safety problems; and for some aluminum veneers that can be installed and removed quickly, it will be too easy to cause accidental touch and unstable installation. Summary of the Invention

[0005] In order to solve the deficiencies of the prior art, the present invention provides an aluminum veneer for building exterior walls. The present invention can not only quickly fix the square shell, but also limit the adjacent limiting fixing mechanisms, thereby preventing the square shell from accidentally falling off. The present invention can not only quickly fix the limiting fixing mechanism with the clamping mechanism, but also quickly release the clamping state, thereby facilitating the rapid installation and disassembly of the aluminum veneer for building exterior walls, thereby facilitating the maintenance of individual aluminum veneers for building exterior walls. Moreover, it can also prevent the control panel from being accidentally touched. The present invention can not only reduce the volume of the aluminum veneer to facilitate transportation, but also facilitate rapid disassembly.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The cam is secured to the rear of the unit and has a plurality of slots for securing the unit to the cam, and the plurality of slots are secured to the rear of the unit and to the rear of the unit.

[0008] Furthermore, the limiting and fixing mechanism includes an L-shaped rod, and the middle part of the L-shaped rod is fixedly connected to the limiting rod; one end of the limiting rod is a threaded end, and four threaded openings are evenly opened around the inner bottom end of the square shell, and the threaded end of the limiting rod is threadedly connected to the corresponding threaded openings; a torsion spring is sleeved on the limiting rod, and the two ends of the torsion spring are respectively fixedly connected to the inner bottom end of the square shell and the L-shaped rod; a mounting frame is provided on one side of the back side of the square shell, and fixing screw holes are opened on the mounting frame, and the fixing screw holes correspond one to one to the threaded openings.

[0009] Furthermore, a straight slot is provided through the side surface of one end of the L-shaped rod, and four abutment rods are evenly fixed on the back side of the control panel in a circumferential direction; the abutment rods correspond to the straight slots one by one, and when the control panel is pressed, the abutment rods can extend into the interior of the corresponding straight slots and approach the middle end of the L-shaped rod.

[0010] Furthermore, when the torsion spring is in a normal state, the L-shaped rod is located in the limiting slot, and the threaded end of the limiting rod does not extend out of the corresponding threaded opening; when the threaded end of the limiting rod extends out of the corresponding threaded opening and the threaded end is screwed to the fixing screw hole, one end of the L-shaped rod extends out of the limiting slot.

[0011] Furthermore, a rotation groove is fixedly provided at the inner bottom end of the square shell, and the threaded opening is located outside the rotation groove; a second limiting ring is rotatably connected in the rotation groove, and the sliding rod is located in the middle of the second limiting ring; four through tubes are evenly fixed on the second limiting ring in an annular direction, and the through tubes correspond to the straight slot openings one by one; one end of the through tube is located in the corresponding straight slot opening and is slidably connected to the straight slot opening; the abutment rod can extend into the interior of the corresponding through tube.

[0012] Furthermore, four circular grooves are evenly arranged in an annular manner on the inner bottom end of the rotating groove, and a clamping mechanism is provided in the circular groove. The clamping mechanism includes a clamping cylinder, and the clamping cylinder is slidingly connected to the circular groove; a second return spring is provided in the circular groove, and the two ends of the second return spring are respectively fixedly connected to the clamping cylinder and the circular groove; the end of the clamping cylinder movably abuts against the second limiting ring.

[0013] Furthermore, the through tube corresponds to the clamping cylinder one by one; when the second limiting ring rotates to slide the through tube from one end of the straight slot close to the middle of the L-shaped rod to one end away from the middle of the L-shaped rod, the through tube is connected to the circular groove.

[0014] Furthermore, the ends of the clamping cylinder and the abutting rod are both configured as rounded corners.

[0015] Furthermore, when the limiting ring abuts against the limiting plate, the control surface plate and the front surface of the square shell are in the same horizontal plane.

[0016] A method for loading and unloading the above-mentioned building exterior wall aluminum single plate comprises the following steps:

[0017] S1. Align the threaded opening of the square housing with the fixing screw hole on the corresponding mounting frame, then rotate the control panel to align the abutment rod of the control panel with the through pipe on the corresponding straight slot;

[0018] S2. Press the control dial to insert the abutment rod into the interior of the through tube. Then, rotate the control dial to drive the second limiting ring to rotate, so that the through tube slides from the end of the straight slot close to the middle of the L-shaped rod to the end away from the middle of the L-shaped rod. At this time, the through tube is connected to the circular slot, the threaded end of the limiting rod extends out of the corresponding threaded opening and is screwed into the fixing screw hole, and one end of the L-shaped rod extends out of the limiting slot.

[0019] S3. Loosen the control panel. Under the reset action of the reset spring, the abutment rod leaves the through-tube and the straight slot. At this time, the clamping cylinder in the circular slot extends into the through-tube under the reset action of the second reset spring to clamp and limit the L-shaped rod to complete the installation.

[0020] S4. When disassembly is required, rotate the control dial to align the abutment rod with the through-tube on the corresponding straight slot, then press the control dial to insert the abutment rod into the inside of the through-tube. At this time, the abutment rod squeezes the engaging cylinder into the inside of the circular slot to release the engaging limit. Finally, rotate the control dial to release the threaded end of the limiting rod from the fixing screw hole. At this time, one end of the L-shaped rod simultaneously extends into the inside of the limiting slot to complete the disassembly.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The cooperation between the control panel of the present invention and the limiting fixing mechanism can not only quickly fix the square shell, but also limit the adjacent limiting fixing mechanisms, thereby preventing the square shell from accidentally falling off. Specifically, by threading the limiting rod of the L-shaped rod with the corresponding threaded opening, the threaded end of the limiting rod can extend out of the corresponding threaded opening when the L-shaped rod is rotated and be screwed and fixed with the fixing screw hole on the mounting frame. On the basis of this fixing method, by pressing the control panel, the abutting rod can be extended into the interior of the corresponding straight slot and close to the middle end of the L-shaped rod, so that The L-shaped rod is controlled to rotate by subsequently rotating the control dial, so that the threaded end of the limit rod extends out of the corresponding threaded opening and is screwed into the fixing screw hole, and one end of the L-shaped rod extends out of the limit slot; in this way, the L-shaped rods in the four limit slots of the square shell can be extended to limit the surrounding limit slots, and at the same time, the threaded ends of the limit rods can be extended out of the corresponding threaded opening and screwed into the fixing screw holes on the mounting frame; even if the square shell becomes loose, it will be limited by the L-shaped rods of the surrounding square shells, thereby preventing the square shell from accidentally falling off.

[0023] (2) The present invention can realize the fast clamping and fixing of the clamping mechanism to the limiting fixing mechanism through the cooperation of the second limiting ring, the clamping mechanism and the limiting fixing mechanism, and can also quickly release the clamping state, which is convenient for the fast installation and disassembly of the building exterior wall aluminum veneer, thereby facilitating the maintenance of a single building exterior wall aluminum veneer; and it can also prevent the control panel from being accidentally touched; specifically, when the control panel is rotated to make the threaded end of the limiting rod extend out of the corresponding threaded opening and the threaded end is screwed to the fixing screw hole, the rotating control panel drives the second limiting ring to rotate, and when the through pipe slides from the end of the straight groove close to the middle of the L-shaped rod to the end away from the middle of the L-shaped rod, the through pipe is connected to the circular groove, and at this time, the circular groove is opened after the control panel is released. The clamping cylinder can automatically extend into the through-tube under the reset action of the second reset spring to clamp and limit the L-shaped rod, thereby realizing rapid clamping and fixing of the limit fixing mechanism. When disassembly is required, the control panel is rotated to align the abutment rod with the through-tube on the corresponding straight slot, and then the control panel is pressed to insert the abutment rod into the inside of the through-tube. At this time, the abutment rod squeezes the clamping cylinder into the inside of the circular groove to release the clamping limit. Finally, the control panel is rotated to release the threaded end of the limit rod from the fixing screw hole, thereby realizing rapid disassembly, thereby facilitating the maintenance of a single aluminum single panel for the exterior wall of a building. Moreover, after the square shell is installed, the aluminum single panel cannot be disassembled by simply rotating or pressing the control panel, thereby preventing the control panel from being accidentally touched.

[0024] (3) The present invention adopts a torsion spring structure design, which can not only position the L-shaped rod in the limiting slot when the square shell is not fixed, thereby reducing the volume of the aluminum plate and facilitating transportation, but also assist in disassembling the square shell so that the threaded end of the limiting rod is unthreaded from the fixing screw hole, thereby facilitating quick disassembly.

[0040] The cooperation between the control panel 300 and the limiting fixing mechanism 400 of the present invention can not only quickly fix the square shell 100, but also limit the adjacent limiting fixing mechanisms 400, thereby preventing the square shell 100 from accidentally falling off; the limiting fixing mechanism 400 will be described in detail later.

[0041] It is worth noting that the square housing 100 and the control panel 300 of the present invention are made of aluminum to improve the aesthetics, and the material of the internal structure can be conventionally selected according to actual conditions.

[0042] Furthermore, the limiting and fixing mechanism 400 includes an L-shaped rod 410, the middle part of which is fixedly connected to the limiting rod 420; one end of the limiting rod 420 is a threaded end 421, and four threaded openings 130 are evenly opened around the inner bottom end of the square shell 100, and the threaded end 421 of the limiting rod 420 is threadedly connected to the corresponding threaded openings 130; a torsion spring 430 is sleeved on the limiting rod 420, and the two ends of the torsion spring 430 are respectively fixedly connected to the inner bottom end of the square shell 100 and the L-shaped rod 410; a mounting frame 200 is provided on one side of the back side of the square shell 100, and a fixing screw hole 210 is opened on the mounting frame 200, and the fixing screw hole 210 corresponds one-to-one to the threaded opening 130.

[0043] It is worth noting that the mounting frame 200 is fixed on the exterior wall of the building. As for the specific fixing method, conventional methods can be selected, such as pre-embedded or bolted, etc., which will not be described in detail here.

[0044] Furthermore, a straight slot 411 is provided through the side surface of one end of the L-shaped rod 410, and four abutment rods 310 are evenly fixed in a circumferential direction on the back of the control panel 300; the abutment rods 310 correspond one-to-one to the straight slots 411, and when the control panel 300 is pressed, the abutment rods 310 can extend into the interior of the corresponding straight slots 411 and approach the middle end of the L-shaped rod 410.

[0045] It is worth noting that, in the normal state, the abutment rod 310 is not in contact with the straight slot 411, and the random rotation of the control panel 300 will not act on the L-shaped rod 410; at the same time, since the control panel 300 is made of an opaque material, if the control panel 300 needs to be pressed to accurately allow the abutment rod 310 to extend into the corresponding straight slot 411, it is also necessary to determine the position through identification marks. This is a conventional setting and will not be described in detail here.

[0046] Furthermore, when the torsion spring 430 is in a normal state, the L-shaped rod 410 is located in the limiting slot 110, and the threaded end 421 of the limiting rod 420 does not extend out of the corresponding threaded opening 130; when the threaded end 421 of the limiting rod 420 extends out of the corresponding threaded opening 130 and the threaded end 421 is threadedly connected to the fixing screw hole 210, one end of the L-shaped rod 410 extends out of the limiting slot 110.

[0047] The present invention uses a method of threaded connection between the limiting rod 420 of the L-shaped rod 410 and the corresponding threaded opening 130, so that when the L-shaped rod 410 is rotated, the threaded end 421 of the limiting rod 420 can extend out of the corresponding threaded opening 130 and be threadedly fixed to the fixing screw hole 210 on the mounting frame 200; based on this fixing method, by pressing the control panel 300, the abutting rod 310 can be extended into the interior of the corresponding straight slot 411 and close to the middle end of the L-shaped rod 410, so that the L-shaped rod 410 can be controlled to rotate by subsequently rotating the control panel 300, so that the threaded end 421 of the limiting rod 420 can extend out of the corresponding threaded opening 130 When the groove 130 and the threaded end 421 are screwed into the fixing screw hole 210, one end of the L-shaped rod 410 extends out of the limiting slot 110; in this way, the L-shaped rod 410 in the four limiting slots 110 of the square shell 100 can be extended to limit the surrounding limiting slots 110, and at the same time, the threaded end 421 of the limiting rod 420 can extend out of the corresponding threaded opening 130 and be screwed and fixed with the fixing screw hole 210 on the mounting frame 200; even if the square shell 100 becomes loose, it will be limited by the L-shaped rods 410 of the surrounding square shells 100, thereby preventing the square shell 100 from accidentally falling off.

[0048] Furthermore, a rotating groove 170 is fixedly provided at the inner bottom end of the square shell 100, and the threaded opening 130 is located outside the rotating groove 170; a second limiting ring 500 is rotatably connected in the rotating groove 170, and the sliding rod 140 is located in the middle of the second limiting ring 500; four through tubes 510 are evenly fixed in an annular direction on the second limiting ring 500, and the through tubes 510 correspond one-to-one to the straight slot openings 411; one end of the through tube 510 is located in the corresponding straight slot opening 411 and is slidably connected to the straight slot opening 411; the abutment rod 310 can extend into the interior of the corresponding through tube 510.

[0049] When the abutment rod 310 extends into the interior of the corresponding through tube 510, by rotating the control panel 300, the second limiting ring 500 rotates synchronously. At the same time, the through tube 510 will also slide in the straight slot 411, thereby driving the L-shaped rod 410 and the limiting rod 420 to rotate.

[0050] Furthermore, four circular grooves 160 are evenly arranged in an annular manner at the inner bottom end of the rotating groove 170, and a clamping mechanism 600 is provided in the circular groove 160. The clamping mechanism 600 includes a clamping cylinder 610, and the clamping cylinder 610 is slidingly connected to the circular groove 160; a second return spring 620 is provided in the circular groove 160, and the two ends of the second return spring 620 are respectively fixedly connected to the clamping cylinder 610 and the circular groove 160; the end of the clamping cylinder 610 movably abuts against the second limiting ring 500.

[0051] Furthermore, the through tube 510 corresponds one-to-one to the clamping cylinder 610; when the second limiting ring 500 rotates to make the through tube 510 slide from one end of the straight slot 411 close to the middle of the L-shaped rod 410 to one end away from the middle of the L-shaped rod 410, the through tube 510 is connected to the circular groove 160.

[0052] The second limiting ring 500, the clamping mechanism 600 and the limiting fixing mechanism 400 are matched, the clamping mechanism 600 can be quickly clamped and fixed to the limiting fixing mechanism 400, the clamping state can be quickly released, the quick installation and disassembly of the building outer wall aluminum veneer are facilitated, the single building outer wall aluminum veneer is maintained and maintained, the control face disc 300 is prevented from being touched by mistake, the clamping cylinder 610 in the circular groove 160 can be automatically inserted into the through pipe 510 to clamp and limit the L-shaped rod 410 under the reset action of the second reset spring 620 when the through pipe 510 is slid from the straight slot 411 to the end away from the middle of the L-shaped rod 410, the quick clamping and fixing of the limiting fixing mechanism 400 are realized, the clamping cylinder 610 is extruded into the interior of the circular groove 160 to release the clamping and limiting when the abutting rod 310 is inserted into the interior of the through pipe 510, the quick disassembly is realized by rotating the control face disc 300 to make the threaded end 421 of the limiting rod 420 and the fixed screw hole 210 unscrewed, the single building outer wall aluminum veneer is maintained and maintained, the control face disc 300 cannot be disassembled after the square shell 100 is installed, and the problem that the control face disc 300 is touched by mistake is prevented.

[0053] Further, the end of the clamping cylinder 610 and the abutting rod 310 is provided with a round corner. The round corner facilitates the movement of the clamping cylinder 610 and the abutting rod 310.

[0054] Further, when the limiting ring 321 abuts against the limiting disc 141, the control face disc 300 and the front surface of the square shell 100 are in the same horizontal plane. The design improves the overall appearance of the aluminum veneer.

[0055] The L-shaped rod 410 is located in the limiting slot 110 when the square shell 100 is not fixed and installed, thereby reducing the volume of the aluminum veneer and facilitating transportation, and the threaded end 421 of the limiting rod 420 and the fixed screw hole 210 are unscrewed to facilitate quick disassembly when the square shell 100 is disassembled.

[0056] A method for assembling and disassembling the building outer wall aluminum veneer, comprising the following steps:

[0057] S1. Align the threaded opening 130 of the square housing 100 with the fixing screw hole 210 on the corresponding mounting frame 200, then rotate the control panel 300 to align the abutting rod 310 of the control panel 300 with the through pipe 510 on the corresponding straight slot 411;

[0058] S2. Press the control panel 300 to insert the abutting rod 310 into the interior of the through tube 510. Then, rotate the control panel 300 to drive the second limiting ring 500 to rotate, so that the through tube 510 slides from the end of the straight slot 411 close to the middle of the L-shaped rod 410 to the end away from the middle of the L-shaped rod 410. At this time, the through tube 510 is connected to the circular groove 160, and the threaded end 421 of the limiting rod 420 extends out of the corresponding threaded opening 130 and is screwed into the fixing screw hole 210. At the same time, one end of the L-shaped rod 410 extends out of the limiting slot 110.

[0059] S3. Loosen the control panel 300. Under the reset action of the reset spring 150, the abutting rod 310 leaves the through tube 510 and the straight slot 411.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several improvements and modifications can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
