Description

Technical Field

[0001] The invention relates to the technical field of suspended ceiling installation, in particular to an indoor suspended ceiling fixing device for building decoration and furnishing engineering. Background Art

[0002] Building decoration and decoration engineering refers to engineering activities that beautify, protect and improve the interior and exterior of a building, involving the transformation and decoration of the interior space of the building, including the treatment of walls, floors, ceilings, and the installation of partitions, doors and windows. The purpose of building decoration and decoration engineering is to enhance the function, aesthetics and comfort of the building, while also reflecting the nature of use and cultural characteristics of the building. This work requires comprehensive consideration of knowledge in multiple fields such as architecture, aesthetics, materials science, and ergonomics. The suspended ceiling is an integral part of building decoration and decoration engineering. The suspended ceiling, also called the ceiling or ceiling, refers to the covering on the top of the indoor space of a building, which is usually located under the floor or roof structure.

[0003] After searching, it is found that there are problems with the existing hangers during use. Since the hangers are installed on the ceiling by drilling holes on the ceiling using expansion bolts, the holes may not fit the upper end of the hangers during the drilling process, which may cause the hangers to tilt when the nuts on the expansion bolts are turned to fix the hangers, which may cause the keels to tilt when the keels are installed later. After the ceiling is fixed with the hangers, water vapor will be generated during the life of the people in the room. The water vapor increases the weight of the ceiling, which increases the burden of the expansion bolts. At the same time, the residents upstairs may make grooves on the ground to lay water and electricity pipes during the decoration process. The grooves on the ground may cause the expansion bolts installed in the ceiling to vibrate. The above two may cause the expansion bolts and the hangers to move downward, resulting in a poor effect of the hangers on the ceiling fixing effect, affecting the staff's use of the hangers to fix the ceiling. Therefore, based on the above search and combined with the existing technology, an indoor ceiling fixing device for building decoration and decoration projects is proposed to solve the above problems.

[0033] The support plate 4 is arranged on the top surface of the base plate 1 to support the height of the expansion bolt 5. The ceiling fixing mechanism 6 is arranged on the top surface of the base plate 1 to fix the ceiling. The ceiling fixing mechanism 6 includes a connecting tube 15, which is installed on the top surface of the base plate 1. A spring three 57 is fixedly installed inside the connecting tube 15. One end of the spring three 57 is fixedly connected to the top surface of the base plate 1. The weight of the structure on the base plate 1 is not enough to pull the spring three 57. A ball head 25 is fixedly installed on the upper end of the connecting tube 15. A connecting sleeve 21 is fixedly installed on the bottom surface of the suction cup 7. The ball head 25 is rotatably connected to the connecting sleeve 21. A level 16 for detecting whether the base plate 1 and the suspension rod 2 are level is fixedly installed on one side of the base plate 1. A plurality of notches are provided on the outer circumferential wall surface of the connecting sleeve 21. The lower end of the connecting sleeve 21 is bent inward to wrap part of the ball head 25. A thread is provided on the outer circumferential wall surface of the connecting sleeve 21. A nut two 22 for locking the angle of the ball head 25 is fixedly installed on the outer circumferential wall surface of the connecting sleeve 21.

[0034] In the process of installing the suspension rod 2, the staff firstly adsorbs the suction cup 1 7 on the ceiling, and then continuously rotates the base plate 1 and the suspension rod 2 to drive the ball head 25 to rotate inside the connecting sleeve 21, and adjusts the base plate 1 and the suspension rod 2 with the cooperation of the level 15 to keep the base plate 1 and the suspension rod 2 level, and then rotates the nut 22 to lock the ball head 25 with the connecting sleeve 21, thereby locking the position of the base plate 1 and the suspension rod 2, and preventing the suspension rod 2 from tilting due to the mismatch between the hole and the suspension rod 2 during installation;

[0035] The ceiling fixing mechanism 6 also includes a support box 23, which is fixedly installed on one side of the base plate 1. The inner bottom surface of the support box 23 is rotatably connected to the bevel gear 46. A support hole 48 is provided on the bottom surface of the support box 23. A fixing ring 51 is fixedly installed on the bottom surface of the bevel gear 46. A bearing seat 44 is fixedly installed on one side of the inner part of the support box 23. The inner part of the bearing seat 44 is rotatably connected to the support rod 42 through the bearing. The lower end of the support rod 42 passes through the bevel gear 46 and extends to the inside of the fixing ring 51. A ratchet 52 is fixedly installed on the bottom surface of the support rod 42. The inner circumferential wall surface of the fixing ring 51 is fixed. A plurality of movable frames 54 are installed, and the outer circumferential wall surface of the ratchet 52 is movably engaged with a latching tooth 53, and two movable rods 55 are fixedly installed on one side of the latching tooth 53. The movable rods 55 penetrate the movable frame 54, and the outer circumferential wall surface of the movable rods 55 is sleeved with a spring 56 for resetting. A knob 26 is fixedly installed on the bottom surface of the ratchet 52, and one end of the spring 56 is fixedly connected to one side of the latching tooth 53, and the other end of the spring 56 is fixedly connected to one side of the inner side of the movable frame 54. The outer circumferential wall surface of the support rod 42 is sleeved with a spring 45, and the support rod 42 is driven to rotate by tightening and releasing the spring 45;

[0036] The staff member rotates the knob 26 to drive the ratchet 52 to rotate. The rotation of the ratchet 52 causes the latching teeth 53 and the movable rod 2 55 to move backward inside the movable frame 54 and compress the spring 2 56. The rotation of the ratchet 52 also drives the support rod 42 to rotate and tightens the spring 45 to store power. At this time, the bevel gear 1 46 does not rotate.

[0037] One side of the mainspring 45 is fixedly connected to one side of the inner part of the support box 23, a mounting frame 38 is fixedly installed inside the support box 23, a support roller 39 is rotatably connected inside the mounting frame 38, one end of the support roller 39 is rotatably connected to a second bevel gear 47 via a one-way bearing, and the second bevel gear 47 and the first bevel gear 46 can only rotate in one direction via the one-way bearing, that is, the rotation direction of the first bevel gear 46 is opposite to the direction when the mainspring 45 is tightened and stored;

[0038] The bevel gear 2 47 is meshed with the bevel gear 1 46. A plurality of support columns 40 are fixedly mounted on the outer circumferential wall of the support roller 39. A positioning block 36 is fixedly mounted on the top surface of the base plate 1. A pronunciation tooth 37 is mounted on the top surface of the positioning block 36 by bolts. The pronunciation tooth 37 penetrates the support box 23 and extends to the inside of the support box 23. The comb teeth on the pronunciation tooth 37 have different lengths and different sounds after being plucked.

[0039] A clamping groove 43 is provided on the top surface of the support rod 42, and the outer side of the clamping groove 43 is wavy. A clamping column 41 is movably clamped inside the clamping groove 43, and the outer wall of the clamping column 41 is also wavy. The two clamp each other to limit the support rod 42. A fixing rod 24 is fixedly installed on the top surface of the clamping column 41. The fixing rod 24 penetrates the top surface of the support box 23 and extends to the outside of the support box 23. A suction cup 27 for adsorbing the wall is fixedly installed on the top surface of the fixing rod 24. The suction cup 27 is at the same height as the suction cup 1 7.

[0040] When the suction cup 1 7 is adsorbed on the ceiling, the suction cup 2 27 will also be adsorbed on the ceiling. After adjusting the level of the base plate 1 and the suspension rod 2, the base plate 1 and the suspension rod 2 are installed on the ceiling using the expansion bolts 5. The dampness of the ceiling increases and the vibration caused by the decoration of the upper residents may cause multiple expansion bolts 5 to move downward from the ceiling. The downward movement of the expansion bolts 5 causes the base plate 1 and the suspension rod 2 to move downward. At this time, the suction cup 1 7 and the suction cup 2 27 are adsorbed on the ceiling and will not move, but the spring 3 57 is stretched, and the base plate 1 and the suspension rod 2 move so that the clamping column 41 The spring 45 drives the support rod 42 to rotate, and the rotation of the support rod 42 causes the ratchet 52 to rotate. At this time, the direction of the ratchet 52 is opposite to the direction of the latching tooth 53, so that when the ratchet 52 rotates, it drives the bevel gear 1 46 to rotate through the latching tooth 53, and the rotation of the bevel gear 1 46 drives the bevel gear 2 47 to rotate, and the rotation of the bevel gear 2 47 drives the support roller 39 to rotate, and the rotation of the support roller 39 causes the support column 40 to move the sound-generating tooth 37 to produce a sound, and this sound is used to warn personnel that there are potential safety hazards in the suspended ceiling and that maintenance is required;

[0041] A mounting block 28 is fixedly installed on the outer circumferential wall surface of the fixed rod 24, and two connecting blocks 29 are fixedly installed on both sides of the mounting block 28. A movable block 30 is rotatably connected between the two connecting blocks 29 through a rotating shaft. A clamping claw 31 is provided on the bottom surface of the movable block 30, and the clamping claw 31 is a U-shaped structure. Two supporting frames 35 are fixedly installed on the top surface of the supporting box 23. The clamping claw 31 is movably engaged with the supporting frame 35. Two movable rods 33 are fixedly installed on the top surface of the clamping claw 31. The upper end of the movable rod 33 passes through the movable block 30 and extends to the outside of the movable block 30. A cover plate 32 is fixedly installed on the top surface of the two movable rods 33. The movable rod 33 is elastically connected to the movable block 30 through a spring 34. The spring 34 is movably sleeved on the outer circumferential wall surface of the movable rod 33. One end of the spring 34 is fixedly connected to the bottom surface of the cover plate 32, and the other end of the spring 34 is fixedly connected to the top surface of the movable block 30.

[0042] After the suction cup 27 is attached to the ceiling, the staff moves the cover plate 32 downward so that the movable rod 1 33 drives the claw 31 to move downward and separate from the support frame 35, and then rotates the movable block 30 outward to drive the claw 31 to rotate outward to a position outside the support frame 35, without the restriction of the claw 31 and the support frame 35, the base plate 1 and the suspension rod 2 move downward to trigger the clamping column 41 and the clamping groove 43;

[0043] With the above technical features, by setting the base plate 1, the workers drill holes on the ceiling according to the positions of the multiple expansion bolts 5 before using the base plate 1 and the suspension rod 2 to fix the main keel.

[0044] The staff attaches the suction cup 1 7 and the suction cup 2 27 to the ceiling. The suction cup 1 7 and the suction cup 2 27 cooperate to preliminarily position the substrate 1 and the suspension rod 2. The staff observes the level 16 on the side of the substrate 1 to determine whether the substrate 1 and the suspension rod 2 are level. If the substrate 1 and the suspension rod 2 are level, no adjustment is required.

[0045] If the base plate 1 and the suspension rod 2 are tilted during the installation of the expansion bolts 5 due to the mismatch between the holes and the expansion bolts 5, the staff adjusts the base plate 1 and the suspension rod 2. The adjustment of the base plate 1 and the suspension rod 2 allows the connecting tube 15 to drive the ball head 25 to rotate inside the connecting sleeve 21. After the base plate 1 and the suspension rod 2 are adjusted to be horizontal, the staff rotates the nut 22. The nut 22 rotates on the outer wall of the connecting sleeve 21 so that the connecting sleeve 21 shrinks inwards to fit the ball head 25, limiting the rotation of the ball head 25, thereby locking the position of the base plate 1 and the suspension rod 2. Next, the staff uses multiple expansion bolts 5 to further fix the base plate 1 and the suspension rod 2 to prevent the base plate 1 and the suspension rod 2 from tilting during the installation process, ensuring that the base plate 1 and the suspension rod 2 are always horizontal during the subsequent process of fixing the ceiling, thereby reducing the difficulty of installing the base plate 1 and the suspension rod 2.

[0046] Secondly, the staff moves the cover plate 32 downward, and the downward movement of the cover plate 32 drives the movable rod 1 33 to move downward on the movable block 30, and at the same time, the spring 1 34 is compressed. The downward movement of the movable rod 1 33 also drives the claw 31 to move downward and separate from the support frame 35. The staff rotates the movable block 30 outward to rotate the claw 31 to a position outside the support frame 35. At this time, the cover plate 32 is released, and the force of the spring 1 34 causes the claw 31 to move upward to prevent the claw 31 and the support frame 35 from being clamped again;

[0047] During the use of the suspended ceiling, water vapor is generated due to indoor life, which increases the overall weight of the suspended ceiling. The increase in the weight of the suspended ceiling also increases the burden of the multiple expansion bolts 5. The decoration of the upper residents may hit the ground, which may further cause the expansion bolts 5 to loosen. The loosening of the expansion bolts 5 causes the entire suspended ceiling, together with the base plate 1 and the suspension rod 2, to move downward. The moving distance is short and difficult to judge with the naked eye. However, during the downward movement, the suction cup 27 is adsorbed on the ceiling. At this time, the spring 3 57 inside the connecting tube 15 is stretched, and the downward movement of the base plate 1 and the suspension rod 2 causes the support rod 42 to move along the clamping column 41 on the fixing rod 24. When the clamping column 41 and the support rod 42 When the clamping groove 43 on the upper part is separated, the clamping column 41 and the clamping groove 43 are lost, and the clockwork 45 drives the support rod 42 to rotate, and the rotation of the support rod 42 drives the ratchet 52 to rotate. At this time, the rotation direction of the ratchet 52 is opposite to the bending direction of the clamping tooth 53. Therefore, the rotation of the ratchet 52 will drive the fixing ring 51 and the bevel gear 1 46 to rotate through the multiple clamping teeth 53, and the rotation of the bevel gear 1 46 drives the bevel gear 2 47 to rotate, and the rotation of the bevel gear 2 47 drives the support roller 39 to rotate. The rotation of the support roller 39 makes the multiple support columns 40 on the outer wall of the support roller 39 to move the pronunciation teeth 37. The pronunciation teeth 37 are moved to make a sound to warn the people in the room that the ceiling needs to be inspected, thereby improving the safety of the ceiling.

[0048] In addition, after the inspection, the staff removes the fixed rod 24 with the clamping column 41 from the support rod 42, and drives the ratchet 52 to rotate by rotating the rotation 57. The rotation of the ratchet 52 causes the clamping tooth 53 to drive the movable rod 2 55 to move backward on the movable frame 54 and compress the spring 2 56. The rotation of the ratchet 52 also drives the support rod 42 to rotate and tightens the spring 45. Then, the fixed rod 24 with the clamping column 41 is inserted into the clamping groove 43 on the support rod 42, so as to apply force to the spring 45 again, so that it can be used repeatedly.

[0049] During this process, the base plate 1 and the suspension rod 2 can be preliminarily positioned by adsorbing the suction cup 7 on the ceiling to facilitate installation. The angles of the base plate 1 and the suspension rod 2 can be adjusted by using the level 16 in coordination with the rotation of the base plate 1 and the suspension rod 2 to prevent the base plate 1 and the suspension rod 2 from tilting during installation, thereby improving the accuracy of subsequent suspended ceilings and improving the aesthetics of the suspended ceiling. Secondly, the support rollers 39, support columns 40 and pronunciation teeth 37 can be used in coordination to provide an early warning when the overall suspended ceiling moves downward due to loosening of the expansion bolts 5, thereby helping to eliminate safety hazards. At the same time, the base plate 1 and the suspension rod 2 can be used again after the hazards are eliminated, thereby achieving a fixing effect on the suspended ceiling and facilitating the installation of the suspended ceiling during building decoration.

[0050] As a preferred implementation in this embodiment, please refer to Figures 1 to 9The top surface of the base plate 1 is threadedly connected with two threaded rods 14, and a bearing is installed on the bottom surface of the support plate 4. The upper end of the threaded rod 14 is fixedly sleeved with the inner circumferential wall surface of the inner ring of the bearing, and the rotation and rise of the threaded rod 14 is converted into the upward movement of the support plate 4 through the bearing. A limiting rod 17 for limiting the movement of the support plate 4 is fixedly installed on the bottom surface of the support plate 4, and the limiting rod 17 passes through the base plate 1 and extends to the outside of the base plate 1;

[0051] The base plate 1 and the suspension rod 2 are initially positioned by adsorbing the suction cup 1 7 and the suction cup 2 27 on the ceiling, and then a hole is punched on the ceiling. The support plate 4 drives the expansion bolt 5 to move upward into the hole by rotating the threaded rod 14. At this time, the limiting rod 17 can limit the movement of the support plate 4.

[0052] Specifically, by setting the suction cup 17, after using the suction cup 17 to absorb the base plate 1 and the suspension rod 2 to the ceiling, the staff marks and punches holes on the ceiling according to the positions of the expansion bolts 5. After punching, the staff rotates the threaded rod 14. The rotation of the threaded rod 14 drives the inner ring of the bearing to rotate. The rotation of the threaded rod 14 also makes the support plate 4 and the expansion bolt 5 move upward until the expansion bolt 5 is moved to the hole in the ceiling. At the same time, the movement of the support plate 4 will also drive the movement of the limiting rod 17. The limiting rod 17 can limit the movement of the support plate 4. Then the staff uses the expansion bolts 5 to further fix the base plate 1 and the suspension rod 2, so as to achieve the fixing effect of the base plate 1 and the suspension rod 2;

[0053] A plurality of elastic sheets 20 are fixedly mounted on one side of the limiting rod 17. The elastic sheets 20 have a certain elasticity and can bend inwards. A support frame 18 is fixedly mounted on the bottom surface of the substrate 1. A clamping block 19 for squeezing the elastic sheets 20 is fixedly mounted on one side of the inner side of the support frame 18. The clamping block 19 is trapezoidal. The support plate 4 drives the limiting rod 17 to move upward so that the elastic sheets 20 will bend inwards due to the squeezing of the clamping block 19. However, if the limiting rod 17 moves downward, the wider upper part of the clamping block 19 will block the elastic sheets 20, thereby limiting the moving direction of the support plate 4.

[0054] Specifically, by setting the limiting rod 17, when the limiting rod 17 moves upward, the elastic sheet 20 thereon will be squeezed and bent inward by the internal clamping block 19 of the support frame 18, but when the limiting rod 17 moves downward, the wider upper end of the clamping block 19 can block the elastic sheet 20, preventing the limiting rod 17 from moving downward with the support plate 4 and the expansion bolt 5, so as to achieve the unidirectional movement of the limiting rod 17, and prevent the support plate 4 and the expansion bolt 5 from moving downward due to the loosening of the threaded rod 14;

[0055] The inner circumferential wall surface of the support hole 48 is provided with an annular groove 49 for supporting the rotation of the bevel gear 1 46. The outer circumferential wall surface of the fixing ring 51 is fixedly sleeved with a support ring 50. The outer circumferential wall surface of the support ring 50 is rotatably connected with the inner circumferential wall surface of the annular groove 49. The rotation of the bevel gear 1 46 drives the support ring 50 to rotate inside the annular groove 49 through the fixing ring 51. The annular groove 49 and the support ring 50 cooperate to support the rotation of the bevel gear 2 47.

[0056] Specifically, by setting the bevel gear 46, the rotation of the bevel gear 46 will drive the fixed ring 51 to rotate, and the rotation of the fixed ring 51 will drive the support ring 50 to rotate inside the annular groove 49 in the inner wall of the support hole 48. The support ring 50 and the annular groove 49 cooperate to limit the rotation of the bevel gear 46, thereby improving the stability of the bevel gear 46 when rotating;

[0057] The bottom surface of the suspension rod 2 is provided with a mounting groove 10, and a top block 11 is slidably sleeved inside the mounting groove 10. The lower end width of the top block 11 is greater than the upper end. In the process of ceiling hanging, the suspension rod 2 passes through the hole on the main keel and fixes the main keel with two movable rods 33. The top block 11 moves inside the mounting groove 10 so that the bottom end of the mounting groove 10 expands outward, thereby restricting the nut 3.

[0058] Specifically, after the main keel is fixed by using the base plate 1 and the suspension rod 2, the staff puts the top block 11 into the installation groove 10 on the bottom surface of the suspension rod 2, and the bottom end of the suspension rod 2 is expanded outward by the top block 11. After the bottom end of the suspension rod 2 is expanded outward, the nut 3 on it can be restricted to prevent the nut 3 from being separated from the suspension rod 2, thereby further improving the stability of the ceiling;

[0059] The top surface of the base plate 1 is provided with two support grooves 9, and a plurality of test papers 8 for detecting water are fixedly installed inside the support grooves 9. The test papers 8 are specifically water-changing test papers. If the water pipes of the upper residents are broken and water is leaking, the water will first drip onto the test papers 8;

[0060] Specifically, by setting the base plate 1 and the suspension rod 2, after the ceiling is completed using the base plate 1 and the suspension rod 2, if the water pipe of the upper resident is broken and water is leaking, the water will first drip onto the test paper 8, and the test paper 8 will change color when it comes into contact with water. Later, the test paper 8 on the base plate 1 may be checked through the central air conditioning inspection port to determine whether water is leaking in the upper resident;

[0061] A positioning rod 12 is fixedly installed on the inner bottom surface of the installation groove 10, and a guide hole 13 is opened on the top surface of the top block 11. The outer circular wall surface of the positioning rod 12 is movably sleeved with the inner circular wall surface of the guide hole 13. When the top block 11 moves downward, it moves along the positioning rod 12, and the positioning rod 12 can guide the movement of the top block 11;

[0062] Specifically, by setting the top block 11, when the top block 11 moves inside the installation groove 10, the positioning rod 12 will enter the inside of the guide hole 13 on the top block 11. The positioning rod 12 and the guide hole 13 can guide the movement of the top block 11 to achieve a guiding effect on the top block 11.

[0063] Working principle: Through the provided suspension rod 2, during the process of installing the suspension rod 2, the staff firstly adsorbs the suction cup 1 7 on the ceiling, and then continuously rotates the base plate 1 and the suspension rod 2 to drive the ball head 25 to rotate inside the connecting sleeve 21, and adjusts the base plate 1 and the suspension rod 2 with the cooperation of the level 15 to keep the base plate 1 and the suspension rod 2 level, and then rotates the nut 22 to lock the ball head 25 with the connecting sleeve 21, thereby locking the position of the base plate 1 and the suspension rod 2 to prevent the suspension rod 2 from tilting;

[0064] Secondly, the base plate 1 and the suspension rod 2 are initially positioned by adsorbing the suction cup 1 7 and the suction cup 2 27 on the ceiling, and then holes are punched on the ceiling, and the support plate 4 drives the expansion bolt 5 to move upward into the hole by rotating the threaded rod 14, so as to facilitate the fixing of the base plate 1;

[0065] Afterwards, after the suction cup 27 is attached to the ceiling, the staff moves the cover plate 32 downward so that the movable rod 1 33 drives the claw 31 to move downward and separate from the support frame 35, and then rotates the movable block 30 outward to drive the claw 31 to rotate outward to a position outside the support frame 35, without the restriction of the claw 31 and the support frame 35, the base plate 1 and the suspension rod 2 move downward to trigger the clamping column 41 and the clamping groove 43;

[0066] In addition, when the suction cup 1 7 is adsorbed on the ceiling, the suction cup 2 27 will also be adsorbed on the ceiling. After adjusting the level of the base plate 1 and the suspension rod 2, the base plate 1 and the suspension rod 2 are installed on the ceiling using the expansion bolts 5. The dampness of the ceiling increases and the vibration caused by the decoration of the upper residents may cause multiple expansion bolts 5 to move downward from the ceiling. The downward movement of the expansion bolts 5 causes the base plate 1 and the suspension rod 2 to move downward. At this time, the suction cup 1 7 and the suction cup 2 27 are adsorbed on the ceiling and will not move, but the spring 3 57 is stretched, and the base plate 1 and the suspension rod 2 move so that the clamping column 41 The spring 45 drives the support rod 42 to rotate, and the rotation of the support rod 42 causes the ratchet 52 to rotate. At this time, the direction of the ratchet 52 is opposite to the direction of the latching tooth 53, so that when the ratchet 52 rotates, it drives the bevel gear 1 46 to rotate through the latching tooth 53, and the rotation of the bevel gear 1 46 drives the bevel gear 2 47 to rotate, and the rotation of the bevel gear 2 47 drives the support roller 39 to rotate, and the rotation of the support roller 39 causes the support column 40 to move the sound-generating tooth 37 to produce a sound, and this sound is used to warn personnel that there are potential safety hazards in the suspended ceiling and that maintenance is required;

[0067] At the same time, the staff turns the knob 26 to drive the ratchet 52 to rotate. The rotation of the ratchet 52 causes the latch 53 and the movable rod 2 55 to move backward inside the movable frame 54 and compress the spring 2 56. The rotation of the ratchet 52 will also drive the support rod 42 to rotate and tighten the spring 45 to store power, which is convenient for multiple uses.

[0068] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
