[0022] Beneficial effects of the present invention:

[0023] 1. The present invention can facilitate the rapid installation of the fixed structure as a whole by providing a first hanging mechanism, and the first hanging mechanism is pressed against the side wall of the wall, which can facilitate the installation of the keel installation mechanism, the hanging keel and the self-retractable installation mechanism. The external medium is injected into the medium cavity through the injection mechanism, and the medium passes through a plurality of pressure reducing mechanisms to push the first sealing piston to slide inside the first tube body. The pressure reducing mechanism buffers the injection impact force of the medium, and the first sealing piston drives the push rod to slide inside the sealing sleeve and compresses the first spring, thereby driving the side wall mounting frame to press against the wall, and the first anti-slip pad increases the friction at the connection between the wall and the side wall mounting frame to prevent the side wall mounting frame from sliding. When the side wall mounting frame is pressed against, the side wall mounting frame is installed on the wall through the first expansion bolt, thereby realizing the secondary reinforcement of the first hanging mechanism.

[0024] 2. The present invention can facilitate the injection of medium into the medium cavity by providing an injection mechanism. The joint is connected to the medium injection tube. Before injecting the medium, the closing rod is rotated by turning the handle to screw the closing rod out of the left threaded sleeve and remove the obstruction in the middle of the injection cavity, so that the medium can smoothly enter the medium injection port through the injection cavity. When the medium injection is completed, the turning handle is reset to the left threaded sleeve to seal the injection cavity to prevent medium leakage.

[0025] 3. The present invention can facilitate buffering of the medium injected into the medium cavity by providing a pressure reducing mechanism. After the medium enters the medium cavity, it flows toward the medium cavity, and the inclined elastic plate and the rubber buffer block contact the medium and deform themselves to absorb the impact force, thereby preventing hydraulic shock and reducing the flow rate of the hydraulic oil, thereby achieving smooth and precise movement of the first sealing piston. The hollow groove inside the rubber buffer block can increase the deformation of the rubber buffer block, so that the rubber buffer block can deform inwardly.

[0026] 4. The present invention provides a second hanging mechanism, which can be easily pressed against the top of the wall to fix the top of the first hanging mechanism. After the first hanging mechanism is fixed on the side wall, the control valve is opened to allow the medium inside the medium cavity to enter the inner cavity of the second tube body through the connecting pipe. After entering the second tube body, the second sealing piston is driven to move upward. The second sealing piston drives the telescopic rod to extend upward out of the second tube body, and drives the top wall mounting frame to move upward and closely contact the wall top, thereby realizing rapid installation of the second hanging mechanism. The second anti-slip pad contacts the wall top to increase the friction between the top wall mounting frame and the wall top. After tightening, the top wall mounting frame is fixed to the wall top by the second expansion bolt, and secondary processing is performed to prevent loose installation.

[0027] 5. The present invention can facilitate the connection between the first hanging mechanism and the suspension keel by providing a keel installation mechanism. The first installation fixture and the second installation fixture are sleeved on the surface of the side wall mounting frame and move with the side wall mounting frame, so that the suspension keel can also move synchronously, and the installation position of the suspension keel is adjusted. The keel body is stuck in the clamp, and the staff holds the hand wheel to pass the threaded rod through the fixing hole and screws it on the clamp to fix the keel body.

[0028] 6. The present invention can facilitate the installation of several self-retractable mounting mechanisms by arranging a hanging keel. The slider is installed in the adjusting slide groove to realize the connection between the mounting plate and the keel body. The position of the slider inside the adjusting slide groove is changed according to the spacing installation requirements of the multi-section aluminum square tube structural parts. After moving to the appropriate position, the limiting bolt is passed through the limiting hole and screwed into the slider to fix the mounting plate. The number of limiting holes is several, and the spacing between the several limiting holes is the same, so that the adjustment of various spacing distances can be realized.

[0029] 7. The present invention can facilitate the fixation of multi-section aluminum square tube structural members by setting up a self-retractable mounting mechanism. The multi-section aluminum square tube structural members are installed on the aluminum square tube mounting members to realize the suspended ceiling installation of the multi-section aluminum square tube structural members, and the overall length of the self-retractable mounting mechanism can be automatically retracted. When the suspension keel moves with the side wall mounting frame, the suspension keel drives the mounting plate to move, and the mounting plate slides at the bottom of the connecting plate, and drives the spring seat to slide inside the sliding groove. The spring seat stretches the second spring, so that the overall length of the self-retractable mounting mechanism can be changed to adapt to the installation of the multi-section aluminum square tube structural members.

[0030] 8. The present invention can connect and support two relatively placed first hanging mechanisms by setting a connecting piece, so that the first hanging mechanism can be smoothly pressed against the side wall, and multiple connecting rods are spliced ​​with each other through the first threaded member and the second threaded member, and are installed on the first tube body through the installation head, so as to realize the installation and fixation of the first hanging mechanism and the connecting piece.

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0047] like Figure 1-13As shown, this embodiment provides a fixing structure of an adjustable aluminum square tube for preventing loose installation, including a first hanging mechanism 100, the first hanging mechanism 100 includes a first tube body 101, an injection mechanism 113 for injecting a medium is installed on the surface of the first tube body 101, a medium cavity 111 connected to the injection mechanism 113 is opened inside the first tube body 101, a plurality of pressure reducing mechanisms 110 are arranged inside the medium cavity 111, a movable first sealing piston 109 is arranged inside the first tube body 101, a push rod 103 is installed at one end of the first sealing piston 109, the push rod 103 extends to the outside of the first tube body 101 and is connected to a side wall mounting frame 108.

[0048] Furthermore, a plurality of first expansion bolts 106 are installed on the side wall mounting frame 108, a first anti-slip pad 107 is fixedly connected to one side of the side wall mounting frame 108, a mounting head 112 is installed at the rear end of the first tube body 101, a sealing sleeve 105 sleeved on the surface of the push rod 103 is installed inside the first tube body 101, a first spring 104 is installed on one side of the sealing sleeve 105, and the other end of the first spring 104 is connected to the first sealing piston 109.

[0049] By providing the first hanging mechanism 100, it is possible to facilitate the rapid installation of the entire fixed structure, and the first hanging mechanism 100 is pressed against the side wall of the wall, which can facilitate the installation of the keel installation mechanism 300, the hanging keel 400 and the self-retractable installation mechanism 500. The external medium is injected into the medium cavity 111 through the injection mechanism 113. The medium passes through a plurality of pressure reducing mechanisms 110 to push the first sealing piston 109 to slide inside the first tube body 101. The pressure reducing mechanism 110 buffers the injection impact of the medium. The first sealing piston 109 drives the push rod 103 to slide inside the sealing sleeve 105 and compresses the first spring 104, thereby driving the side wall mounting frame 108 to press against the wall. The first anti-slip pad 107 increases the friction at the connection between the wall and the side wall mounting frame 108 to prevent the side wall mounting frame 108 from sliding. When the side wall mounting frame 108 is pressed against, the side wall mounting frame 108 is installed on the wall through the first expansion bolt 106, thereby realizing the secondary reinforcement of the first hanging mechanism 100.

[0050] Furthermore, the injection mechanism 113 includes an injector 1131, which is installed on the surface of the first tube body 101. An injection cavity 1135 connected to the medium cavity 111 is opened inside the injector 1131. A joint 1132 is installed on the top of the injector 1131. A threaded sleeve 1133 is installed on the surface of the injector 1131. A closing rod 1134 is threadedly connected to the inner part of the threaded sleeve 1133. The closing rod 1134 is located at the middle end of the inner cavity of the injection cavity 1135 to separate it. A turning handle 1136 is fixedly connected to one end of the closing rod 1134.

[0051] By setting up the injection mechanism 113, it is convenient to inject the medium into the medium cavity 111. The joint 1132 is connected to the medium injection tube. Before injecting the medium, the closing rod 1134 is rotated by the turning handle 1136 to screw the closing rod 1134 out of the left threaded sleeve 1133, and remove the obstruction in the middle of the injection cavity 1135, so that the medium can pass through the injection cavity 1135 and enter the medium injection port 102 smoothly. When the medium injection is completed, the turning handle 1136 is reset to the left threaded sleeve 1133 to seal the injection cavity 1135 to prevent medium leakage.

[0052] Furthermore, the pressure reducing mechanism 110 includes a ring body 1101 installed on the inner wall of the medium cavity 111, a plurality of inclined elastic plates 1102 are installed on one side of the ring body 1101, a rubber buffer block 1104 is installed on the outer side of the inclined elastic plate 1102, the rubber buffer block 1104 is connected to the inner wall of the medium cavity 111, and a hollow groove 1103 is opened inside the rubber buffer block 1104.

[0053] By providing the pressure reducing mechanism 110, it is possible to facilitate buffering of the medium injected into the medium cavity 111. After the medium enters the medium cavity 111, it flows toward the medium cavity 111, and the inclined elastic plate 1102 and the rubber buffer block 1104 come into contact with the medium, and deform themselves to absorb the impact force, thereby preventing hydraulic shock and reducing the flow rate of the hydraulic oil, thereby achieving smooth and precise movement of the first sealing piston 109. The hollow groove 1103 inside the rubber buffer block 1104 can increase the deformation of the rubber buffer block 1104, so that the rubber buffer block 1104 can deform inwardly.

[0054] Furthermore, it also includes a second hanging mechanism 200, which is installed on the surface of the first hanging mechanism 100 and is connected thereto.

[0055] Furthermore, the second hanging mechanism 200 includes a seat body 201 installed on the surface of the first tube body 101, a connecting pipe 213 is installed on the top of the seat body 201, and a control valve 211 is installed on the top of the seat body 201, a medium injection port 102 connected to the connecting pipe 213 is opened on the surface of the first tube body 101, the top of the control valve 211 is connected to the second tube body 210, and a second sealing piston 214 is movably connected inside the second tube body 210, and a telescopic rod 209 is fixedly connected to the top of the second sealing piston 214, the top of the telescopic rod 209 passes through the second tube body 210 and is fixedly connected to a top wall mounting frame 206, a plurality of second expansion bolts 208 are installed on the top wall mounting frame 206, and a second anti-slip pad 207 is fixedly connected to the top of the top wall mounting frame 206.

[0056] Preferably, the inclined elastic plate 1102 is made of elastic material.

[0057] By setting the second hanging mechanism 200, it can be convenient to abut against the top of the wall to fix the top of the first hanging mechanism 100. After the first hanging mechanism 100 is fixed on the side wall, the control valve 211 is opened to allow the medium inside the medium cavity 111 to enter the inner cavity of the second tube body 210 through the connecting pipe 213, and then drive the second sealing piston 214 to move upward after entering the second tube body 210. The second sealing piston 214 drives the telescopic rod 209 to extend upward from the second tube body 210, and drives the top wall mounting frame 206 to move upward and closely contact the wall top, so as to realize the rapid installation of the second hanging mechanism 200. The second anti-slip pad 207 contacts the wall top to increase the friction between the top wall mounting frame 206 and the wall top. After abutting tightly, the top wall mounting frame 206 is fixed to the wall top by the second expansion bolt 208, and secondary processing is performed to prevent the installation from loosening.

[0058] During the extension of the telescopic rod 209, the fixed seat 205 is driven to move synchronously, and the fixed seat 205 drives the supporting slide bar 204 to slide inside the auxiliary supporting tube 203, the auxiliary supporting tube 203 rotates inside the sliding frame 202, and the sliding frame 202 slides inside the limiting frame 212, so that the supporting slide bar 204 and the auxiliary supporting tube 203 can provide side support for the extended telescopic rod 209 to prevent the telescopic rod 209 from breaking and bending.

[0059] Furthermore, the top of the seat body 201 is fixedly connected to a limiting frame 212, the limiting frame 212 is movably connected to a sliding frame 202, the sliding frame 202 is rotatably connected to an auxiliary support tube 203, the auxiliary support tube 203 is movably connected to a retractable supporting slide rod 204, the top of the supporting slide rod 204 is rotatably connected to a fixed seat 205, and the fixed seat 205 is sleeved on the surface of the telescopic rod 209.

[0060] Through the coordinated use of the first hanging mechanism 100 and the second hanging mechanism 200, it is convenient to quickly press against the wall and can adapt to different indoor spaces of buildings. By injecting a driving medium into the first hanging mechanism 100 and the second hanging mechanism 200 to make them press against the side walls and the top wall of the wall, rapid installation can be achieved and loose installation can be prevented. The injected medium is one of hydraulic oil, compressed air, expansive cement and liquid resin. Traditional fixing methods may involve multi-step installation and adjustment, which is time-consuming. The use of a driving medium to drive the structure to expand and contract can achieve rapid, one-step installation. Only the medium needs to be injected to automatically press against the wall, which greatly improves the installation efficiency.

[0061] The existing fixed structure may become loose during long-term use due to factors such as temperature changes, building micro-seismicity, and load changes. The first hanging mechanism 100 and the second hanging mechanism 200 are respectively pressed against the side wall and the top wall to form multiple points of contact and constraint, thereby enhancing the overall stability of the structure and more effectively resisting installation looseness caused by various factors.

[0062] Traditional fixing methods often assume that the wall is rigid, but in actual situations, the wall may have slight deformations, such as thermal expansion and contraction and settlement. The side wall mounting bracket 108 and the top wall mounting bracket 206 can adapt to the wall deformation to a certain extent, and maintain effective contact with the wall by adjusting the medium pressure, thereby avoiding fixation failure caused by wall deformation.

[0063] Furthermore, it also includes a keel installation mechanism 300 , which is sleeved on the surface of the first hanging mechanism 100 .

[0064] Furthermore, it also includes a suspension keel 400 , which is installed inside the keel installation mechanism 300 , and the suspension keel 400 includes a keel body 401 .

[0065] Furthermore, the keel mounting mechanism 300 includes a first mounting fixture 301 and a second mounting fixture 302 which are sleeved on the surface of the side wall mounting frame 108. The second mounting fixture 302 is installed on the top of the first mounting fixture 301. The bottom of the first mounting fixture 301 is fixedly connected with a fixing piece 306, and one end of the fixing piece 306 is fixedly connected with a clamping piece 303. The keel body 401 is installed inside the first mounting fixture 301. The clamping piece 303 is threadedly connected with a threaded rod 304 for limiting the keel body 401. A handwheel 305 is installed at one end of the threaded rod 304. The keel body 401 is provided with a fixing hole 403 used in conjunction with the threaded rod 304.

[0066] By setting up the keel installation mechanism 300, it is convenient to connect the first hanging mechanism 100 and the suspension keel 400. The first installation clamp 301 and the second installation clamp 302 are mounted on the surface of the side wall mounting frame 108 and move with the side wall mounting frame 108, so that the suspension keel 400 can also move synchronously, and the installation position of the suspension keel 400 is adjusted. The keel body 401 is stuck in the clamp 303. The staff holds the hand wheel 305 to pass the threaded rod 304 through the fixing hole 403 and screws it on the clamp 303 to fix the keel body 401.

[0067] By setting up the hanging keel 400, it is convenient to install several self-retractable mounting mechanisms 500, and the slider 507 is installed in the adjusting slide groove 402 to realize the connection between the mounting plate 501 and the keel body 401. According to the spacing installation requirements of the multi-section aluminum square tube structural member 700, the position of the slider 507 inside the adjusting slide groove 402 is changed. When it is moved to the appropriate position, the limiting bolt 508 is passed through the limiting hole 404 and screwed into the slider 507 to fix the mounting plate 501. The number of limiting holes 404 is several, and the spacing between the several limiting holes 404 is the same, so that the adjustment of various spacing distances can be realized.

[0068] Furthermore, it also includes a self-telescopic mounting mechanism 500 , which is in multiple numbers and is installed at the bottom of the suspension keel 400 .

[0069] Furthermore, the self-retractable mounting mechanism 500 includes a mounting plate 501, a bent plate 506 is provided at one end of the mounting plate 501, the bent plate 506 is movably connected to the surface of the keel body 401, a slider 507 is installed at one end of the bent plate 506, an adjustment groove 402 for accommodating the slider 507 is provided in the keel body 401, a limiting bolt 508 is provided on one side of the slider 507, a limiting hole 404 is provided on one side of the keel body 401, the limiting bolt 508 passes through the limiting hole 404 and is threadedly connected to the slider 507 to limit it, and a plurality of aluminum square tube mounting parts 509 for installing the multi-section aluminum square tube structural parts 700 are provided at the bottom of the mounting plate 501.

[0070] Furthermore, a connecting plate 505 is movably connected to the top of the mounting plate 501, a sliding groove 502 is provided on the connecting plate 505, a spring seat 504 located in the inner cavity of the sliding groove 502 is installed on the top of the mounting plate 501, and a second spring 503 is installed on the opposite side of the spring seat 504.

[0071] By setting up a self-retractable mounting mechanism 500, it is possible to facilitate the fixation of the multi-section aluminum square tube structural member 700. The multi-section aluminum square tube structural member 700 is installed on the aluminum square tube mounting member 509 to realize the suspended ceiling installation of the multi-section aluminum square tube structural member 700. Moreover, the overall length of the self-retractable mounting mechanism 500 can be automatically retracted. When the suspension keel 400 moves with the side wall mounting frame 108, the suspension keel 400 drives the mounting plate 501 to move. The mounting plate 501 slides at the bottom of the connecting plate 505 and drives the spring seat 504 to slide inside the sliding groove 502. The spring seat 504 stretches the second spring 503, so that the overall length of the self-retractable mounting mechanism 500 can be changed to adapt to the installation of the multi-section aluminum square tube structural member 700.

[0072] Furthermore, it also includes connecting members 600, which are multiple in number and threadedly connected to each other, and multiple connecting members 600 are installed on the first hanging mechanism 100 to connect them.

[0073] Furthermore, the connecting member 600 includes a connecting rod 601 , a first threaded member 602 is installed at one end of the connecting rod 601 , and a second threaded member 603 is installed at the other end of the connecting rod 601 .

[0074] Furthermore, the mounting head 112 is threadedly connected to one of the first threaded member 602 and the second threaded member 603 .

[0075] By setting up the connecting piece 600, the two relatively placed first hanging mechanisms 100 can be connected and supported, so that the first hanging mechanism 100 can be smoothly pressed against the side wall, and the multiple connecting rods 601 are spliced ​​with each other through the first threaded member 602 and the second threaded member 603, and are installed on the first tube body 101 through the installation head 112, so as to realize the installation and fixation of the first hanging mechanism 100 and the connecting piece 600.

[0076] When installing the fixed structure of the aluminum square tube:

[0077] First, a plurality of connecting members 600 are assembled, and then the two first hanging mechanisms 100 are connected to each other through the connecting members 600 to ensure the stability of the overall structure.

[0078] The first mounting fixture 301 and the second mounting fixture 302 are sleeved on the surface of the side wall mounting frame 108, and the keel body 401 is installed inside the first mounting fixture 301 through the fixing piece 306 and the clamping piece 303, and the hand wheel 305 is turned to screw the threaded rod 304 into the clamping piece 303 to fix the keel body 401.

[0079] The first suspension mechanism 100 is placed at the installation position on the top of the building interior, and the driving medium is injected into the injector 1131. The medium enters the medium cavity 111 through the injection cavity 1135. The medium passes through the pressure reducing mechanism 110 in turn to buffer the impact force and ensure the smooth movement of the first sealing piston 109.

[0080] The driving medium pushes the first sealing piston 109 to slide in the first tube 101, compressing the first spring 104, thereby driving the push rod 103 and the side wall mounting frame 108 to press against the wall. At this time, the first anti-skid pad 107 increases the friction force to prevent the side wall mounting frame 108 from sliding.

[0081] When the side wall mounting frame 108 is completely tightened, it is reinforced for a second time using the first expansion bolt 106. Then the injection channel is closed, and the closing rod 1134 is screwed into the threaded sleeve 1133 to prevent leakage of the medium.

[0082] Then, the control valve 211 is opened to allow the medium inside the first hanging mechanism 100 to flow into the second tube body 210. The medium pushes the second sealing piston 214 to move upward, driving the telescopic rod 209 and the top wall mounting bracket 206 to extend upward until the top wall mounting bracket 206 is pressed against the top of the wall.

[0083] The top wall mounting frame 206 is fixed to the top of the wall using the second expansion bolts 208 for secondary reinforcement. At this time, the second anti-slip pad 207 increases the friction between the top wall mounting frame 206 and the top of the wall to prevent the installation from loosening.

[0084] The slider 507 is installed in the adjusting slide groove 402 , and the position of the slider 507 in the adjusting slide groove 402 is adjusted according to the spacing requirements of the multi-section aluminum square tube structural member 700 .

[0085] When the slider 507 moves to a suitable position, the limiting bolt 508 passes through the limiting hole 404 and is screwed into the slider 507 to fix the mounting plate 501 .

[0086] The multi-section aluminum square tube structural member 700 is installed on the aluminum square tube mounting member 509 to complete the suspended ceiling installation of the aluminum square tube.
