Description

Technical Field

[0001] This application relates to the field of aluminum square tube installation technology, and in particular to a multi-angle adjustment combination device for an aluminum square tube spiral shape. Background Technology

[0002] Aluminum square tubes are a type of aluminum ceiling material used for interior decoration. They have a distinctive ceiling effect, smooth lines, and neat arrangement. Larger span aluminum square tubes are often used in venues such as airports and stadiums. Many venues often adopt irregular curved surface designs for aesthetic reasons. Large span aluminum square tubes cannot be processed in one go and are often processed in sections. This requires adjusting the angles when combining adjacent aluminum square tubes.

[0003] The invention patent with announcement number CN120331447B proposes an installation structure for U-shaped hyperboloid aluminum square tubes and the U-shaped hyperboloid aluminum square tubes themselves. It adopts an axisymmetrically arranged head-to-head installation structure to adjust or correct the tilt of the aluminum square tubes, thereby adapting to the needs of angle adjustment of the aluminum square tubes.

[0004] While the above-mentioned technical solutions can be used to connect and combine aluminum square tubes, they require slotting in the aluminum square tubes and modifying and customizing the structure of the aluminum square tubes. They also have requirements on the specifications and shapes of the aluminum square tubes, and different projects need to be customized separately, which makes production and processing relatively inconvenient. Therefore, this application proposes a new technical solution. Summary of the Invention

A locking nut is threaded to one end of the bolt three near the base. The base has an adjustment port in the transverse direction. The bolt three passes through the adjustment port, and the locking nut is located in the adjustment port.

[0011] Optionally, the inner ring body is a hollow structure and has a feed nozzle that communicates with the inner cavity. The feed nozzle is fitted with a suitable cap and is used for injecting cement slurry or glue. The inner ring body is provided with a piston rod in the radial direction. The piston of the piston rod is slidably connected to the inner wall of the inner ring body, and the movement channel of the piston rod communicates with the inner cavity of the inner ring body. There are multiple piston rods, and the multiple piston rods are distributed around the inner ring body.

[0012] Optionally, the feed nozzle is fixed with an elastic soft membrane and a sealing membrane. A crack is formed in the center of the soft membrane. The side wall of the feed nozzle is provided with a liquid outlet channel for releasing overflowing slurry.

[0026] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0027] This application discloses a multi-angle adjustment combination device for an aluminum square tube spiral shape.

[0028] Reference Figure 1 and Figure 2 The multi-angle adjustment combination device for aluminum square tube spiral shape includes an angle adjustment mechanism 1, which includes a base 11, an outer ring 12 and an inner ring 13.

[0029] In this embodiment, the base 11 is a vertically arranged plate structure, which can be fixed to the keel or the building's support column by welding or bolting. The outer ring 12 and inner ring 13 are metal rings in this embodiment; for example, the outer ring 12 can be made of curved aluminum alloy, and the inner ring 13 can be made of curved brushed stainless steel.

[0030] The two rings are each divided into two parts radially. One half of the outer ring 12 is fixed (e.g., welded) to the base 11 with the opening of the half facing upwards. The other half of the outer ring 12 is fastened to the lower half with the opening facing downwards. The outer ring 12 is provided with fasteners for connecting the two halves of the outer ring 12. In this embodiment, the fasteners can be screws.

[0031] The inner ring 13 is located inside the outer ring 12. The two parts are the same as the outer ring 12, with one upper and one lower part interlocking. The inner ring 13 is provided with bolts 14 for connecting the two halves of the inner ring 13.

[0032] In this embodiment, the ends of the aluminum square tubes are cylindrical. Two aluminum square tubes that need to be joined are inserted into the same set of inner ring 13 and outer ring 12 for joining. Then, the two parts of the inner ring 13 and the two parts of the outer ring 12 are locked to achieve the combination connection of the aluminum square tubes. At the same time, since the angle adjustment mechanism 1 can be adjusted arbitrarily, adjusting the angle adjustment mechanism 1 to the preset angle can adapt to the needs of angle changes of large-span aluminum square tubes. There is no need to make additional slots in the aluminum square tubes or customize special aluminum square tubes according to project requirements, which improves the convenience of production and processing of large-span aluminum square tubes and meets the needs of connection and combination between irregular aluminum square tubes.

[0033] The inner ring 13 mentioned above can be made of curved brushed stainless steel. Its function is to improve the corrosion resistance of the inner ring 13, and the brushed treatment enhances the friction of the contact surface of the inner ring 13, allowing the aluminum square tube to be fixed more firmly. The outer ring 12 covers the inner ring 13, providing protection and ensuring a more secure fastening.

[0034] Since the aluminum square tube is directly inserted into the inner ring 13 for connection, the end of the aluminum square tube needs to be made into a cylindrical shape, which is still somewhat inconvenient. Therefore, the following design is made:

[0035] A transition tube 15 is provided inside the inner ring body 13. The transition tube 15 is designed according to the end shape of the aluminum square tube to be connected, and can be matched. For example, the transition tube 15 is inserted into the inner ring body 13, and its two ends can be stainless steel round tubes with curved angles, respectively adapting to the ends of two pre-set interconnected aluminum square tubes.

[0036] Based on the above settings, it is no longer necessary to make the ends of the aluminum square tube into a cylindrical shape, thus making processing and use relatively convenient.

[0037] One issue arises when using the structure described in the above embodiment: the installation angle of the base 11 is determined by referring to the orientation of the aluminum square tube end. However, the position of the other aluminum square tube that needs to be connected is often not yet determined, which can easily lead to deviations in the position adjustment of the base 11 due to a lack of reference. Therefore, the following settings are made:

[0038] In another embodiment of this application:

[0039] Reference Figure 3The outer ring 12 is a flexible structure, and each half of the outer ring 12 includes a reference block 121 and flexible pieces 122 connected to the two symmetrical sides of the reference block 121. The reference blocks 121 are symmetrically distributed vertically. The lower reference block 121 is fixed to the base 11. The inner ring 13 is rotatably connected to the reference block 121. The fasteners include a hard plate and two bolts for passing through the hard plate. The hard plate is used to be embedded in the edge of the flexible piece 122 or pressed on the flexible piece 122. Then, the two flexible pieces 122 are fixed by passing through the hard plate with the bolts.

[0040] With the above settings, after the transition tube 15 passes through the inner ring 13, the angle of the inner ring 13 can be adjusted. Since the outer ring 12 is a flexible structure, it will not hinder the rotation of the inner ring 13. After the two flexible pieces 122 are overlapped and fixed, the flexible pieces 122 can still cover the inner ring 13, playing a certain protective role. At the same time, the angle can be finely adjusted, improving the accuracy of angle adjustment when installing aluminum square tubes.

[0041] Since the inner ring 13 and the fastener are rotatably connected, they are prone to movement during installation if not locked, resulting in angular displacement after installation. Therefore, the following settings are made:

[0042] This application also includes a locking assembly 2 for locking the reference block 121 and the inner ring 13. The locking assembly 2 includes a bolt 21 rotatably connected to the base. One end of the bolt 21 near the base 11 is threaded with a locking nut 22. The base 11 has an adjustment port in the transverse direction. The bolt 21 passes through the adjustment port, and the locking nut 22 is located in the adjustment port.

[0043] When in use, by moving the locking nut 22 to expose the adjustment port, the locking nut 22 can be rotated to lock the bolt 3 21. The part of the bolt 3 21 away from the base 11 passes through the reference block 121 and the inner ring 13, and the end is embedded in the inner ring 13, so as not to obstruct the transition tube 15 from passing through the inner ring 13. After the transition tube 15 passes through the inner ring 13, the bolt 3 21 is pressed against the transition tube 15 and locked, thereby locking the inner ring 13 and the transition tube 15 so that they no longer move.

[0044] Since the aforementioned method requires the use of a transition tube 15 to fix the aluminum square tube, and the transition tube 15 is needed every time the aluminum square tube is installed, the convenience is not very high. Therefore, a method is proposed that allows for the secure installation of the aluminum square tube without the need for a transition tube 15. In another embodiment of this application:

[0045] Reference Figure 4 and Figure 5Each half of the inner ring 13 is a hollow structure and is provided with a feed nozzle 131 that connects to the inner cavity. The feed nozzle 131 is equipped with a suitable cap 132. The feed nozzle 131 is used to inject cement slurry or glue, which can be injected through a syringe. The inner ring 13 is provided with a piston rod 133 in the radial direction. The piston of the piston rod 133 is located in the middle section of the rod and is slidably connected to the inner wall of the inner ring 13. The moving channel of the piston rod 133 connects to the inner cavity of the inner ring 13. That is, one end of the piston rod 133 is located inside the inner ring 13 and the other end extends out of the inner wall of the inner ring 13. There are multiple piston rods 133 and multiple piston rods 133 are distributed around the inner ring 13.

[0046] With the above setup, the aluminum square tube is first inserted through the inner ring 13, and cement slurry or glue is injected into the feed nozzle 131. As more and more cement slurry or glue enters the inner ring 13, it will gradually push out the piston rod 133. Thus, the end of the piston rod 133 extending out of the inner ring 13 slowly abuts against the aluminum square tube until multiple piston rods 133 are completely attached to the surface of the aluminum square tube, fixing the aluminum square tube. After that, the cement slurry or glue will solidify, locking the angle and position of the aluminum square tube.

[0047] When cement slurry or glue is injected into the inner ring 13, as the amount of cement slurry or glue inside the inner ring 13 gradually increases, after the injection stops, some cement slurry or glue may overflow through the inlet 131 through the gap in the sealing cap 132, resulting in a decrease in the pressure on the piston rod 133 and affecting the firmness of the aluminum square tube. Therefore, the following settings are made:

[0048] Reference Figure 6 The feed nozzle 131 is fixed with an elastic soft membrane 134 and a sealing membrane 135. The soft membrane 134 and the sealing membrane 135 can be made of rubber. A crack is formed in the center of the soft membrane 134 to facilitate the insertion of the discharge end of the injection device. The side wall of the feed nozzle 131 is provided with a liquid outlet channel 136 for releasing the overflowing slurry. One end of the liquid outlet channel 136 is located inside the soft membrane 134, and the other end is located outside the soft membrane 134. The sealing membrane 135 is fixed inside the feed nozzle 131 and blocks the external end of the liquid outlet channel 136, so as to facilitate the gradual overflow of cement slurry, glue, etc. into the sealing membrane 135 through the liquid outlet channel 136.

[0049] With the above configuration, when injecting cement slurry or glue, the discharge end of the injection device will abut against the end of the liquid outlet channel 136 located outside the soft membrane 134. After the cement slurry or glue is filled, during the process of pulling out the injection device, the blockage of the liquid outlet channel 136 is gradually released, so that the cement slurry or glue will overflow along the liquid outlet channel 136 and then gradually flow into the sealing membrane 135. The sealing membrane 135 gradually expands and finally seals the inlet 131. According to this method, the characteristic that the cement slurry and glue will overflow after being filled can be used to seal the inlet 131, thereby reducing the impact on the pushing pressure of the piston rod 133, while eliminating the need for complicated operations and making it more convenient to use.

[0050] Since the cement slurry or adhesive takes a certain amount of time to solidify, if the aluminum square tube moves due to accidental contact or other reasons during the solidification process, it may change the fixed angle. Workers cannot stay in place for an extended period to wait for the cement slurry or adhesive to solidify and completely lock the piston rod 133 and the aluminum square tube. Therefore, the following settings are implemented:

[0051] In another embodiment of this application:

[0052] Reference Figure 4 and Figure 7 A detection sleeve 137 is fixed to the outer wall of the inner ring 13. The piston 133 is inserted into the detection sleeve 137 at one end away from the center of the inner ring 13 and is slidably connected. The inner wall of the detection sleeve 137 is a conductive structure, such as metal. The outer wall of the detection sleeve 137 can be made of insulating material. The section of the piston rod 133 that extends into the inner cavity of the inner ring 13 is a conductive structure and its surface is insulated. A sealing ring is set between the detection sleeve 137 and the piston rod 133 to effectively prevent leakage or slurry from entering the detection sleeve 137. Wires are connected to the outer end of the detection sleeve 137 and the end of the piston rod 133 near the piston, respectively.

[0053] In use, connect the detection sleeve 137 and piston rod 133 of the same group to the positive and negative terminals respectively. When the piston rod 133 slides relative to the detection sleeve 137, the resistance between the two wires will change due to the connection position of the wires on them, that is, the current will change.

[0054] Therefore, after fixing the aluminum square tube using the inner ring body 13, each set of detection sleeves 137 and piston rods 133 on each inner ring body 13 will have a corresponding current parameter, which, together with the position of the set of detection sleeves 137 and piston rods 133, forms an identification code—current value + position.

[0055] Therefore, by simply observing and comparing the identification code information of each inner ring 13 at different times, it is possible to determine whether the aluminum square tube has shifted.

[0056] Therefore, by intermittently detecting the current on the conductor and comparing the current records at different times before and after, it can be determined whether the installation angle of the aluminum square tube has shifted after installation.

[0057] Reference Figure 7 and Figure 8 This application also includes a signal acquisition module 3 and a remote terminal. The signal acquisition module 3 includes a housing 31 and a current sampling unit 32, a controller and a wireless communication unit installed on the housing 31. The housing 31 can be a box-shaped structure, and the controller can be an MCU controller. It is electrically connected to the wireless communication unit and the current sampling unit 32, and is integrated on the corresponding circuit board. The circuit board is built into the box-shaped structure.

[0058] The box-shaped structure has multiple conductive posts fixed for docking, which are used for the wires of the docking detection sleeve 137 and the piston rod 133 respectively; the current sampling unit 32 can collect the current parameters on the conductive posts, and the current sampling unit 32 can be a DC current sensor.

[0059] Understandably, the wires of each inner ring 13 are bundled together and the ends form plugs 34 for insertion.

[0060] With the above settings, the current sampling unit 32 can autonomously collect the current data on the wires of the detection sleeve 137 and piston rod 133, and transmit it to the controller through the wireless communication unit. The controller is connected to a remote terminal, which can be a worker's mobile phone or handheld device with a display. Through the remote terminal, the current data of multiple piston rods 133 and whether the data has changed can be obtained, thereby determining whether the angle of the installed aluminum square tube has changed. It is convenient to use and easy to understand.

[0061] In another embodiment of this application, considering that the above-mentioned setup requires an inner ring body 13 to be equipped with a current sampling unit 32, which is inconvenient to use and increases costs, the following setup is made:

[0062] Multiple busbars 33 are fixed inside the housing 31, and the current sampling unit 32 is configured to detect the current on the busbars 33.

[0063] The number of busbars 33 is the same as the number of detection sleeves 137 in the inner ring body 13;

[0064] The connector 34 of each inner ring 13 has pins fixed in the same number as the detection sleeve 137, with two pins per group.

[0065] An electronic switch unit 35 is provided inside the housing 31. The electronic switch unit 35 is used to electrically connect each plug 34 and bus 33. Assuming that the bus 33 is the positive wire, a negative wire is also provided inside the housing 31. One of the pins in each group is electrically connected to the negative wire after being inserted into the housing 31, and the other is used to electrically connect the electronic switch unit 35 to the bus 33 after being inserted into the housing 31.

[0066] The electronic switching unit 35 is electrically connected to the controller. The electronic switching unit 35 includes a switching circuit composed of a transistor switch and a relay.

[0067] like Figure 8 As shown, it includes a transistor T1 connected to the controller via a resistor R2, the collector of the transistor being connected in series with the coil of a relay K1, and the normally open contact S1 of the relay K1 being connected in series with one of the pins in each group of busbar 33.

[0068] The housing 31 is provided with multiple sockets for the plugs 34 of the wire harness of the inner ring 13 to be inserted.

[0069] In use, the controller is configured to turn on each plug 34 in turn through each electronic switch unit 35. During this process, the controller reads the readings of the current sampling unit 32 on each bus 33. The readings at the same time are a set of data, and a set of data corresponds to a plug 34, that is, a set of data corresponds to a ring body. Thus, one signal acquisition module 3 can be used with multiple inner ring bodies 13, which makes the use of this application more convenient and lower in cost.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
