Description

Technical Field

[0001] The present invention relates to a decorative combined structure for interior wall finish construction and an installation method thereof, belonging to the technical field of building construction. Background Art

[0002] When decorating the interior walls of a bathroom, kitchen, etc., it is usually necessary to install a suspended ceiling and decorative panels on the ceiling wall.

[0003] When installing a traditional suspended ceiling, due to the use of an integrated keel, and then placing the decorative panel on the keel for covering, the mobility of the decorative panel is limited, making it unable to freely flip and rotate. In this way, it cannot cooperate with indoor lighting and light for attitude conversion, which is not conducive to the interaction between the decorative panel, the wall, and the light, and is not conducive to the display of indoor lighting effects. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to provide a decorative combined structure for interior wall finish construction and an installation method thereof, which solves the problem that in the prior art, the mobility of the decorative panel is limited, it cannot freely flip and rotate, thus unable to cooperate with indoor lighting and light for attitude conversion, not conducive to the interaction between the decorative panel, the wall, and the light, and not conducive to the display of indoor lighting effects.

[0005] The technical problem to be solved by the present invention is achieved by the following technical solutions: A decorative combined structure for interior wall finish construction, including

[0006] A decorative panel for covering the ceiling wall. A clamping groove is provided on the largest side surface of the decorative panel, and expansion bolts are embedded in the wall.

[0007] A threaded joint, which is vertically inserted into the wall and threadedly connected to the impact bolt.

[0008] A clamping sleeve, fixed at the end of the threaded joint away from the wall. A clamping component is arranged in the clamping sleeve.

[0009] A connecting sleeve, fixed at the end of the clamping sleeve away from the threaded joint. The connecting sleeve and the clamping sleeve are provided in a hollow shape. The end of the connecting sleeve away from the clamping sleeve is open.

[0010] A clamping pipe, coaxially arranged with the connecting sleeve. The end of the clamping pipe extends from the connecting sleeve into the clamping sleeve and is clamped with the clamping component. The connection end of the clamping pipe and the clamping component is an annular groove surrounding the axial direction of the clamping pipe.

[0011] A clamping disc, hinged to the end of the clamping pipe that does not extend into the connecting sleeve. The end of the clamping disc away from the clamping pipe is connected to the decorative panel. The outer contour of the clamping disc is the same as the inner contour of the clamping groove of the decorative panel.

[0012] Among them, the snap - fit component is snap - fitted with the annular groove, which only restricts the axial movement of the snap - fit pipe.

[0013] By adopting the above - mentioned technical solution, after the snap - fit pipe is snap - fitted with the snap - fit component, since the snap - fit disc is hinged to the end of the snap - fit pipe, and at this time the decorative panel is installed on the snap - fit disc, the decorative panel can be flipped along the hinge between the snap - fit disc and the snap - fit pipe. At the same time, by rotating the snap - fit pipe, the decorative panel can be rotated, so as to achieve arbitrary adjustment of the flipping angle and flipping direction of the decorative panel. At this time, the decorative panel can be adjusted in real time according to the position of the indoor light source, thereby enhancing the indoor lighting effect and being beneficial to improving the linkage between the indoor wall and the lighting effect.

[0014] The present invention is further configured as: the snap - fit component includes

[0015] a snap - fit cavity, radially opened on the inner wall of the snap - fit sleeve,

[0016] a retraction block, arranged in the snap - fit cavity,

[0017] a snap - fit block, arranged at one end of the retraction block close to the threaded joint. The snap - fit block is slidably connected to the retraction block. The snap - fit block slides radially along the snap - fit sleeve and abuts against and is snap - fitted with the snap - fit pipe. One side of the snap - fit block close to the axis of the snap - fit sleeve is an inclined slope, and the slope inclines towards the direction close to the axis of the snap - fit sleeve along the direction from the connecting sleeve to the snap - fit sleeve.

[0018] a compression spring, arranged at the connection between the retraction block and the snap - fit block. The part of the snap - fit block facing the retraction block extends into the retraction block. The compression spring is connected to the snap - fit block, and the compression spring gives the snap - fit block an elastic force towards the direction of the axis of the snap - fit sleeve.

[0019] By adopting the above - mentioned technical solution, when the end of the snap - fit pipe is inserted into the snap - fit sleeve, at this time the end of the snap - fit pipe abuts against the inclined slope of the snap - fit block. Under the pressure, the snap - fit block moves away from the snap - fit pipe, and at this time the compression spring is compressed. When the end of the snap - fit block enters the annular groove of the snap - fit pipe, the snap - fit block moves towards the snap - fit pipe to reset under the elastic force of the compression spring. At this time, the snap - fit block is snap - fitted with the snap - fit pipe, and at this time the snap - fit pipe cannot move axially, thus ensuring the stability of the snap - fit pipe. At this time, the snap - fit pipe can rotate freely, achieving the purpose of both restricting the movement of the snap - fit pipe and ensuring that the snap - fit pipe can rotate.

[0020] The present invention is further configured as: the retraction block is slidably arranged obliquely to the axial direction of the snap - fit sleeve. The sliding direction of the end of the retraction block close to the threaded joint converges towards the axial direction of the snap - fit sleeve. A retraction spring is arranged at the end of the retraction block away from the snap - fit block, and the retraction spring gives the retraction block an elastic force along the sliding direction towards the direction close to the threaded joint.

[0021] By adopting the above technical solution, when the clamping pipe is subjected to a large axial tensile force, at this time, the clamping pipe is axially stressed towards the opening direction of the connecting sleeve. At this time, the clamping block is subjected to pressure. Under the action of the pressure, the clamping block presses the retraction block to slide. At this time, the retraction spring is compressed by the force, so that the clamping block and the retraction block move downward. Since the sliding direction of the retraction block is oblique, at this time, the retraction block and the clamping block are displaced away from the clamping pipe. When the clamping block is disengaged from the clamping of the clamping pipe, at this time, the clamping pipe resumes axial movement, and at this time, the clamping pipe can be pulled out from the opening of the connecting sleeve, improving the disassembly speed of the clamping pipe and facilitating the user to replace the clamping pipe and the clamping disc.

[0022] The present invention is further configured as follows: a connecting component is provided at the connection between the clamping disc and the decorative plate, and the connecting component includes

[0023] a disassembly sliding groove, which is opened on the clamping disc,

[0024] a combined block, which is slidably arranged in the disassembly sliding groove. The combined block is L-shaped. The horizontal end of the combined block passes through the lateral curved surface of the clamping disc, and the vertical end of the combined block is perpendicular to the clamping disc.

[0025] a spring sleeve rod, which is arranged in the disassembly sliding groove. The spring sleeve rod abuts against the vertical end of the combined block and the inner wall of the disassembly sliding groove respectively. The elastic force direction of the spring sleeve rod extends along the horizontal end of the combined block.

[0026] Wherein, the horizontal end of the combined block extends into the decorative plate to form a clamping structure.

[0027] By adopting the above technical solution, by pushing the vertical end of the combined block towards the direction of the spring sleeve rod, at this time, the horizontal end of the combined block is retracted into the clamping disc. At this time, the clamping disc is just inserted into the clamping groove in the middle of the decorative plate. Then, release the vertical end of the combined block. Under the elastic force of the spring sleeve rod, the end of the horizontal end of the combined block is inserted into the inner wall of the clamping groove in the middle of the decorative plate. At this time, the decorative plate and the clamping disc are completed with clamping. When disassembling, only need to make the combined block retract into the clamping disc through the above process to complete the separation of the clamping disc and the decorative plate, thereby reducing the disassembly difficulty of the clamping disc and the decorative plate and being beneficial for the user to quickly replace the decorative plate by himself.

[0028] The present invention is further configured as follows: a

[0029] bending baffle is provided on the outer side of the connecting sleeve. The bending baffle is fixed at the end of the connecting sleeve away from the clamping sleeve. A plurality of bending baffles are arranged in an equidistant circumferential array along the axial direction of the connecting sleeve.

[0030] an inflatable block is arranged around the outer side of the connecting sleeve. An inflatable cavity is arranged in the inflatable block.

[0031] a sealing sliding plate is slidably arranged along the axial direction of the connecting sleeve in the inflatable cavity. The connection between the sealing sliding plate and the inflatable cavity is sealed.

[0032] A vent hole is opened on the side of the inflation cavity away from the clamping sleeve.

[0033] An air duct is fixedly connected to the side surface of the sealing sliding plate away from the vent hole, and the other end of the air duct extends into the connecting sleeve.

[0034] Inside the connecting sleeve, there is

[0035] An expansion ring that slides axially along the connecting sleeve. The expansion ring is hollow, and the side of the expansion ring facing the clamping sleeve is fixedly connected to the air duct. The hollow inside of the expansion ring communicates with the air duct.

[0036] An air inlet hole is arranged at the end of the air duct connected to the sealing sliding plate. The air inlet hole is located on the side surface of the air duct, and the air inlet hole directly communicates the air duct with the inflation cavity.

[0037] By adopting the above technical solution, when the clamping pipe is subjected to a tensile force in the axial direction away from the threaded joint and disengages from the clamping assembly, the clamping pipe will abut against the expansion ring during the process of being pulled out of the connecting sleeve. At this time, the expansion ring slides towards the opening direction of the connecting sleeve. During the sliding process of the expansion ring, it pulls the air duct towards the inside of the connecting sleeve. At this time, the air duct pulls the sealing sliding plate in the direction away from the vent hole. At this time, the air pressure on the side of the inflation cavity away from the vent hole of the sealing sliding plate increases, and the gas enters the air duct through the air inlet hole and finally enters the expansion ring to make the expansion ring expand. The expansion ring fits tightly with the inner wall of the connecting sleeve and the fitting pressure gradually increases, so that the friction force between the expansion ring and the inner wall of the connecting sleeve becomes larger, thereby reducing the movement speed of the clamping pipe when it disengages from the connecting sleeve, reducing the safety risk during the disassembly of the clamping pipe, and avoiding damage to the user and its surrounding environment due to the rapid flying out of the clamping pipe.

[0038] The present invention is further configured as: a limiting block is fixed at one end of the connecting sleeve close to the clamping sleeve, and the end of the clamping pipe extending into the clamping sleeve is chamfered.

[0039] By adopting the above technical solution, the limiting block can limit the one-way movement length of the expansion ring in the connecting sleeve. When the clamping pipe is inserted into the connecting sleeve, the chamfered part of the clamping pipe abuts against the expansion ring, thereby pushing the expansion ring towards the direction close to the limiting block. When the expansion ring abuts against the limiting block, the expansion ring stops moving. At this time, the clamping pipe extrudes the expansion ring under the guidance of the chamfer, and finally the expansion ring is sleeved outside the clamping pipe. The clamping pipe moves into the clamping sleeve and is clamped with the clamping device, improving the convenience during the insertion of the clamping pipe and avoiding the situation where the excessive movement of the expansion ring affects the clamping of the clamping assembly.

[0040] The present invention is further configured as: a pull rope is arranged at the vertical end of the combined block, and the other end of the pull rope is fixedly connected to the inner side of the bent baffle. The bent baffle is made of an elastic material.

[0041] By adopting the above technical scheme, when the expansion ring expands and moves to the bending baffle, the end of the bending baffle away from the connecting sleeve is bent in the direction away from the axis of the connecting sleeve, and at the same time, the clamping tube and the clamping disk move in the direction away from the connecting sleeve. At this time, the pull rope gradually changes from a relaxed state to a tensioned state. When the pull rope is fully tensioned, as the bending baffle continues to bend, the pull rope pulls the combination block toward the direction close to the spring sleeve rod and retracts into the clamping disk, thereby disconnecting the decorative panel from the clamping disk. This can avoid the situation where the decorative panel is subjected to a large load, that is, when the decorative panel is held to drive the clamping disk and the clamping tube to be pulled out of the connecting sleeve, the clamping tube and the clamping disk are damaged due to excessive force causing the clamping disk and the clamping tube to be disengaged too quickly, thereby ensuring the service life of the clamping disk and the clamping tube when the decorative panel is subjected to a large load.

[0042] The present invention is further configured as follows: a collar is sleeved on the outer side of the connecting sleeve, the collar is located at one end of the connecting sleeve away from the clamping sleeve, and a connecting rope is fixedly connected between the collar and the decorative plate.

[0043] By adopting the above technical solution, after the clamping disc is separated from the decorative panel, the decorative panel continues to move away from the connecting sleeve under the action of gravity, but at this time the clamping tube and the clamping disc are not subjected to the additional load tension and are decelerated under the action of friction, but at this time the bending baffle has been bent, and when the decorative panel moves, the connecting rope pulls the ring to make the ring move away from the clamping sleeve. At this time, due to the bending of the bending baffle, the continued movement of the ring is restricted. At this time, the decorative panel can be hung on the bending baffle through the ring, which prevents the decorative panel from falling directly to the ground and being damaged, thereby protecting the decorative panel from damage and directly extending the service life of the decorative panel.

[0044] The present invention is further configured as follows: elastic sealing sheets are symmetrically fixed in the air inlet, opposite ends of the elastic sealing sheets are abutted for sealing, and the inflation cavity is located on one side of the sealing sliding plate away from the air vent and is filled with compressed gas.

[0045] By adopting the above technical solution, by filling the inflation cavity with compressed gas and as the space filled with compressed gas gradually decreases, the internal air pressure is further increased, thereby pushing the elastic sealing sheet open and entering into the air duct, thereby expanding the expansion ring. In this way, the amount of gas entering the expansion ring will increase, and the expansion amount of the expansion ring will increase, making the deceleration of the clamping tube and the bending of the bending baffle more effective, which is beneficial to the action of the above process.

[0046] A method for installing a composite facing structure for indoor wall facing construction, the method comprising:

[0047] S1: Screw the threaded joint into the indoor wall to connect the connecting sleeve and the clamping sleeve to the wall;

[0048] S2: Insert the end of the clamping pipe away from the clamping disc through the opening at the end of the connecting sleeve. Finally, move the end of the clamping pipe into the clamping sleeve and engage it with the clamping component.

[0049] S3: Align the decorative panel with the clamping disc and connect them cooperatively.

[0050] S4: Repeat the steps of S1 - S3 to make multiple decorative panels distributed in a rectangular array.

[0051] By adopting the above technical solution, the decorative panel can be quickly connected to the wall. At the same time, the inclination angle of the decorative panel can be adjusted manually, thereby improving the ability of the decorative panel to adapt to indoor lighting and ensuring the stability of the decorative panel.

[0052] The beneficial effects of the present invention are as follows:

[0053] 1. After the clamping pipe is engaged with the clamping component, since the clamping disc is hinged to the end of the clamping pipe, at this time, the decorative panel is installed on the clamping disc, and the decorative panel can be flipped along the hinge between the clamping disc and the clamping pipe. At the same time, by rotating the clamping pipe, the decorative panel can be rotated, so as to adjust the flipping angle and flipping direction of the decorative panel arbitrarily. At this time, the decorative panel can be adjusted in real time according to the position of the indoor light source, thereby enhancing the indoor lighting effect and being beneficial to improving the linkage between the indoor wall and the lighting effect.

[0054] 2. When the clamping pipe is subjected to a large axial tensile force, at this time, the clamping pipe is axially stressed towards the opening direction of the connecting sleeve. At this time, the clamping block is under pressure. Under the action of the pressure, the clamping block presses the retraction block to slide. At this time, the retraction spring is compressed by the force, so that the clamping block and the retraction block move downward. Since the sliding direction of the retraction block is oblique, at this time, the retraction block and the clamping block displace away from the clamping pipe. When the clamping block is disengaged from the clamping pipe, at this time, the clamping pipe resumes axial movement, and at this time, the clamping pipe can be pulled out from the opening of the connecting sleeve, which improves the disassembly speed of the clamping pipe and is convenient for the user to replace the clamping pipe and the clamping disc.

[0055] 3. When the clamping pipe is subjected to a tensile force in the axial direction away from the threaded joint and disengages from the clamping assembly, the clamping pipe will abut against the expansion ring during the process of being pulled out from the connecting sleeve. At this time, the expansion ring slides towards the opening direction of the connecting sleeve. During the sliding process of the expansion ring, the air duct is pulled towards the inside of the connecting sleeve. At this time, the air duct pulls the sealing sliding plate away from the ventilation hole. At this time, the air pressure on the side of the inflation cavity away from the ventilation hole where the sealing sliding plate is located increases, and the gas enters the air duct through the air inlet hole and finally enters the expansion ring to cause the expansion ring to expand. The expansion ring fits tightly with the inner wall of the connecting sleeve and the fitting pressure gradually increases, so that the friction force between the expansion ring and the inner wall of the connecting sleeve becomes larger, thereby reducing the movement speed of the clamping pipe when it disengages from the connecting sleeve, reducing the safety risk during the disassembly of the clamping pipe, and avoiding damage to the user and the surrounding environment due to the rapid flying out of the clamping pipe.

Detailed Embodiments

[0064] For easy understanding of the technical means, creative features, achieved objectives and effects of the present invention, the present invention will be further described below with reference to specific illustrations.

[0065] As Figure 1-7 shown, a decorative combination structure for indoor wall surface construction includes a decorative board 10, a clamping disc 13, a connecting sleeve 20, a clamping sleeve 22, a threaded joint 23, a clamping pipe 24 and a clamping component. The decorative board 10 is used to cover the ceiling wall. A clamping groove is provided on the largest side surface of the decorative board 10. Expansion bolts are embedded in the wall. The threaded joint 23 is vertically inserted into the wall and is threadedly connected to the impact bolt. The clamping sleeve 22 is fixed at the end of the threaded joint 23 away from the wall, and a clamping component is arranged in the clamping sleeve 22. The connecting sleeve 20 is fixed at the end of the clamping sleeve 22 away from the threaded joint 23. The connecting sleeve 20 and the clamping sleeve 22 are provided in a hollow shape, and the end of the connecting sleeve 20 away from the clamping sleeve 22 is open. The clamping pipe 24 is coaxially arranged with the connecting sleeve 20. The end of the clamping pipe 24 extends from the connecting sleeve 20 into the clamping sleeve 22 and is clamped with the clamping component. The connecting end of the clamping pipe 24 and the clamping component is an annular groove surrounding the axis of the clamping pipe 24. The end of the clamping pipe 24 extending into the clamping sleeve 22 is chamfered. The clamping disc 13 is hinged to the end of the clamping pipe 24 that does not extend into the connecting sleeve 20. The end of the clamping disc 13 away from the clamping pipe 24 is connected to the decorative board 10. The outer contour of the clamping disc 13 is the same as the inner contour of the clamping groove of the decorative board 10. Among them, the clamping of the clamping component and the annular groove only restricts the axial movement of the clamping pipe 24.

[0066] As Figure 3 and Figure 4As shown in the figure, the clamping component includes a clamping cavity 25, a clamping block 26, a compression spring 27, and a retraction block 28. The clamping cavity 25 is radially formed on the inner wall of the clamping sleeve 22. There are two clamping cavities 25, which are symmetrically arranged. The retraction block 28 is arranged in the clamping cavity 25. The clamping block 26 is arranged at one end of the retraction block 28 close to the threaded joint 23. The clamping block 26 is slidably connected to the retraction block 28. The clamping block 26 slides radially along the clamping sleeve 22 and abuts against and clamps the clamping pipe 24. One side of the clamping block 26 close to the axis of the clamping sleeve 22 is an inclined plane, and the inclined plane inclines towards the direction close to the axis of the clamping sleeve 22 along the direction from the connecting sleeve 20 to the clamping sleeve 22. The compression spring 27 is arranged at the connection between the retraction block 28 and the clamping block 26. The part of the clamping block 26 facing the retraction block 28 extends into the retraction block 28. The compression spring 27 is connected to the clamping block 26, and the compression spring 27 gives the clamping block 26 an elastic force towards the axis direction of the clamping sleeve 22. The retraction block 28 is slidably arranged obliquely to the axial direction of the clamping sleeve 22. The sliding direction of one end of the retraction block 28 close to the threaded joint 23 converges towards the axial direction of the clamping sleeve 22. A retraction spring 29 is arranged at one end of the retraction block 28 away from the clamping block 26, and the retraction spring 29 gives the retraction block 28 an elastic force towards the direction close to the threaded joint 23 along the sliding direction.

[0067] As Figure 1 and Figure 2 shown in the figure, a connection component 40 is arranged at the connection between the clamping disc 13 and the decorative board 10. The connection component 40 includes a disassembly sliding groove 14, a spring sleeve rod 15, and a combined block 16. The disassembly sliding groove 14 is formed on the clamping disc 13. The combined block 16 is slidably arranged in the disassembly sliding groove 14. The combined block 16 is arranged in an L shape. The horizontal end of the combined block 16 passes through the lateral curved surface of the clamping disc 13, and the vertical end of the combined block 16 is perpendicular to the clamping disc 13. The spring sleeve rod 15 is arranged in the disassembly sliding groove 14. The spring sleeve rod 15 abuts against the vertical end of the combined block 16 and the inner wall of the disassembly sliding groove 14 respectively. The elastic force direction of the spring sleeve rod 15 extends along the horizontal end of the combined block 16. Among them, the horizontal end of the combined block 16 extends into the decorative board 10 to form a clamping structure. A pull rope 17 is arranged at the vertical end of the combined block 16. When the bending baffle 21 is not deformed, the pull rope 17 is just tensioned when the end of the clamping pipe 24 is pulled out from the bending baffle 21. When the bending baffle 21 is deformed, the pull rope 17 is in a tensioned state when the clamping pipe 24 is not pulled out from the bending baffle 21.

[0068] As Figure 2 , 4 and Figure 5As shown in the figure, a bent baffle 21, an inflatable block 30, an air duct 32, a sealed sliding plate 33 and a ventilation hole 34 are arranged outside the connecting sleeve 20. The bent baffle 21 is fixed at the end of the connecting sleeve 20 away from the clamping sleeve 22. A plurality of bent baffles 21 are arranged in a circumferential array at equal intervals along the axial direction of the connecting sleeve 20. One end of the bent baffle 21 is fixedly connected to the pull rope 17. The bent baffle 21 is made of an elastic material. The inflatable block 30 is arranged around the outside of the connecting sleeve 20, and an inflatable cavity 35 is arranged inside the inflatable block 30. The sealed sliding plate 33 is slidably arranged in the inflatable cavity 35 along the axial direction of the connecting sleeve 20, and the connection between the sealed sliding plate 33 and the inflatable cavity 35 is sealed. The ventilation hole 34 is opened on the side of the inflatable cavity 35 away from the clamping sleeve 22. The air duct 32 is fixedly connected to the side surface of the sealed sliding plate 33 away from the ventilation hole 34, and the other end of the air duct 32 extends into the inside of the connecting sleeve 20. An expansion ring 31 and an air inlet hole 37 are arranged inside the connecting sleeve 20. The expansion ring 31 slides along the axial direction of the connecting sleeve 20. The expansion ring 31 is hollow. The side of the expansion ring 31 facing the clamping sleeve 22 is fixedly connected to the air duct 32. The hollow inside of the expansion ring 31 is communicated with the air duct 32. A limiting block 39 is fixed at one end of the connecting sleeve 20 close to the clamping sleeve 22. The limiting block 39 is used to limit the axial sliding of the expansion ring 31. The air inlet hole 37 is arranged at the end where the air duct 32 is connected to the sealed sliding plate 33. The air inlet hole 37 is located on the side surface of the air duct 32. The air inlet hole 37 directly communicates the air duct 32 with the inflatable cavity 35. Elastic sealing pieces 38 are symmetrically fixed in the air inlet hole 37. The opposite ends of the elastic sealing pieces 38 are abutted and sealed. Compressed gas is filled in the space on the side of the inflatable cavity 35 away from the ventilation hole 34 where the sealed sliding plate 33 is located.

[0069] As Figure 1 shown, a collar 12 is sleeved outside the connecting sleeve 20. The collar 12 is located at the end of the connecting sleeve 20 away from the clamping sleeve 22. A connecting rope 11 is fixedly connected between the collar 12 and the decorative plate 10.

[0070] After the clamping pipe 24 is clamped with the clamping assembly, since the clamping disc 13 is hinged to the end of the clamping pipe 24, at this time, the decorative plate 10 is installed on the clamping disc 13. The decorative plate 10 can be turned along the hinge between the clamping disc 13 and the clamping pipe 24. At the same time, by rotating the clamping pipe 24, the decorative plate 10 can be rotated, so as to arbitrarily adjust the turning angle and turning direction of the decorative plate 10. At this time, the decorative plate 10 can be adjusted in real time according to the position of the indoor light source, thereby enhancing the indoor lighting effect and being beneficial to improving the linkage between the indoor wall and the lighting effect.

[0071] When the end of the clamping pipe 24 is inserted into the clamping sleeve 22, the end of the clamping pipe 24 abuts against the inclined surface of the clamping block 26. Under the action of pressure, the clamping block 26 moves away from the clamping pipe 24, and at this time, the pressure spring 27 is compressed. When the end of the clamping block 26 enters the annular groove of the clamping pipe 24, the clamping block 26 moves back towards the clamping pipe 24 under the elastic force of the pressure spring 27 to reset. At this time, the clamping block 26 is clamped with the clamping pipe 24, and at this time, the clamping pipe 24 cannot move axially, thus ensuring the stability of the clamping pipe 24. At this time, the clamping pipe 24 can rotate freely, achieving the purpose of both restricting the movement of the clamping pipe 24 and ensuring that the clamping pipe 24 can rotate. When the clamping pipe 24 is subjected to a large axial tensile force, at this time, the clamping pipe 24 is axially stressed towards the opening direction of the connecting sleeve 20. At this time, the clamping block 26 is subjected to pressure. Under the action of pressure, the clamping block 26 presses the retraction block 28 to slide, and at this time, the retraction spring 29 is stressed and compressed, so that the clamping block 26 and the retraction block 28 move downward. Since the sliding direction of the retraction block 28 is oblique, at this time, the retraction block 28 and the clamping block 26 displace away from the clamping pipe 24. When the clamping block 26 is disengaged from the clamping pipe 24, at this time, the clamping pipe 24 resumes axial movement, and at this time, the clamping pipe 24 can be pulled out from the opening of the connecting sleeve 20, improving the disassembly speed of the clamping pipe 24 and facilitating the user to replace the clamping pipe 24 and the clamping disc 13.

[0072] By pushing the vertical end of the combined block 16 towards the direction of the spring sleeve rod 15, at this time, the horizontal end of the combined block 16 is retracted into the clamping disc 13. At this time, the clamping disc 13 just inserts into the clamping groove in the middle of the decorative plate 10. Then release the vertical end of the combined block 16. Under the elastic force of the spring sleeve rod 15, the end of the horizontal end of the combined block 16 inserts into the inner wall of the clamping groove in the middle of the decorative plate 10. At this time, the decorative plate 10 and the clamping disc 13 are completed with clamping. When disassembling, only need to make the combined block 16 retract into the clamping disc 13 through the above process to complete the separation of the clamping disc 13 and the decorative plate 10, thus reducing the disassembly difficulty of the clamping disc 13 and the decorative plate 10 and being beneficial for the user to quickly replace the decorative plate 10 by himself.

[0073] When the clamping pipe 24 is subjected to a tensile force in the axial direction away from the threaded joint 23 and disengages from the clamping assembly, the clamping pipe 24 will abut against the expansion ring 31 during the process of being pulled out of the connecting sleeve 20. At this time, the expansion ring 31 slides in the direction of the opening of the connecting sleeve 20. During the sliding process of the expansion ring 31, the air guide pipe 32 is pulled towards the inside of the connecting sleeve 20. At this time, the air guide pipe 32 pulls the sealing sliding plate 33 in the direction away from the ventilation hole 34. At this time, the air pressure on the side of the inflation cavity 35 away from the ventilation hole 34 and on the side of the sealing sliding plate 33 increases, and the gas enters the air guide pipe 32 through the air inlet hole 37 and finally enters the expansion ring 31 to cause the expansion ring 31 to expand. The expansion ring 31 fits tightly against the inner wall of the connecting sleeve 20 and the fitting pressure gradually increases, so that the frictional force between the expansion ring 31 and the inner wall of the connecting sleeve 20 becomes larger, thereby reducing the moving speed of the clamping pipe 24 when it disengages from the connecting sleeve 20, reducing the safety risk during the disassembly of the clamping pipe 24, and avoiding damage to the user and its surrounding environment due to the rapid flying out of the clamping pipe 24.

[0074] The limit block 39 can limit the one-way movement length of the expansion ring 31 in the connecting sleeve 20. When the clamping pipe 24 is inserted into the connecting sleeve 20, the chamfered part of the clamping pipe 24 abuts against the expansion ring 31, thereby pushing the expansion ring 31 in the direction close to the limit block 39. When the expansion ring 31 abuts against the limit block 39, the expansion ring 31 stops moving. At this time, the clamping pipe 24 extrudes the expansion ring 31 under the guidance of the chamfer, and finally the expansion ring 31 is sleeved outside the clamping pipe 24. The clamping pipe 24 moves into the clamping sleeve 22 and is clamped with the clamping device, which improves the convenience during the insertion of the clamping pipe 24 and at the same time avoids the situation where the excessive movement of the expansion ring 31 affects the clamping of the clamping assembly. When the expansion ring 31 expands and moves to the bending baffle 21, the end of the bending baffle 21 away from the connecting sleeve 20 bends in the direction away from the axis of the connecting sleeve 20. At the same time, the clamping pipe 24 and the clamping disc 13 move in the direction away from the connecting sleeve 20. At this time, the pull rope 17 gradually changes from a relaxed state to a tensioned state. After the pull rope 17 is completely tensioned, as the bending baffle 21 continues to bend, the pull rope 17 pulls the combined block 16 to move in the direction close to the spring sleeve rod 15 and retracts into the clamping disc 13, so that the decorative plate 10 is disengaged from the clamping disc 13. This can avoid the situation where when the decorative plate 10 is subjected to a large load, that is, when the decorative plate 10 is held to drive the clamping disc 13 and the clamping pipe 24 to be pulled out of the connecting sleeve 20, the excessive force causes the clamping pipe 24 and the clamping disc 13 to disengage too quickly, resulting in damage to the clamping disc 13 and the clamping pipe 24, thereby ensuring the service life of the clamping disc 13 and the clamping pipe 24 under the condition that the decorative plate 10 bears a large load.

[0075] After the snap - on plate 13 is separated from the decorative plate 10, the decorative plate 10 continues to move away from the connecting sleeve 20 under the action of gravity. At this time, the snap - on pipe 24 and the snap - on plate 13 are not subjected to additional load tension and decelerate under the action of friction. However, the bending baffle 21 has already been bent. At this time, when the decorative plate 10 moves, it pulls the collar 12 through the connecting rope 11, causing the collar 12 to move away from the snap - on sleeve 22. At this time, due to the bending of the bending baffle 21, the continuous movement of the collar 12 is restricted. At this time, the decorative plate 10 can be hung on the bending baffle 21 through the collar 12, preventing the decorative plate 10 from directly falling to the ground and being damaged, protecting the decorative plate 10 from damage and directly extending the service life of the decorative plate 10. By filling compressed gas in the inflation cavity 35, as the space for filling compressed gas gradually decreases, the internal air pressure further increases, thus pushing open the elastic sealing piece 38 and entering the air guide pipe 32, and then causing the expansion ring 31 to expand. In this way, the amount of gas entering the expansion ring 31 will become larger. At this time, the expansion amount of the expansion ring 31 will become larger, making the deceleration of the snap - on pipe 24 and the bending of the bending baffle 21 more effective, which is beneficial to the operation of the above - mentioned process.

Finally, move the end of the snap - on pipe 24 into the snap - on sleeve 22 and engage it with the snap - on component. The snap - on process is the same as the above - mentioned process;

[0079] S3: Align the decorative plate 10 with the snap - on plate 13 and connect them. The user can snap - connect the decorative plate 10 with the snap - on plate 13 through the combination block 16 by the above - mentioned process;

[0080] S4: Repeat the steps of S1 - S3 to make multiple decorative plates 10 distributed in a rectangular array, thereby forming a complete wall finish (as Figure 7 described), and a gap can be left between adjacent decorative plates 10 for the decorative plates 10 to be flipped.

[0081] Through the connecting sleeve 20 and the snap - on sleeve 22, the decorative plate 10 can be quickly connected to the wall. At the same time, the inclination angle of the decorative plate 10 can be manually adjusted, thereby improving the ability of the decorative plate 10 to adapt to indoor lighting and ensuring the stability of the decorative plate 10.
