Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, it relates to an adjustable positioning device for ceiling joists in interior decoration. Background Technology

[0002] In building decoration projects, the ceiling is an important part of interior decoration. Its construction quality directly affects the aesthetics, flatness and safety of the interior space. The ceiling keel, as the core load-bearing frame supporting the ceiling decorative layer (such as gypsum board and aluminum composite panel), has its installation positioning accuracy and efficiency as one of the key factors determining the quality of ceiling construction.

[0003] Currently, the common construction process for installing clip-on keel is as follows: First, several fixing screws are driven into predetermined positions on the ceiling. Then, the first nut is screwed into each of these fixing screws and tightened. Next, the clip-on keel is inserted into the fixing screws. Finally, a second nut is screwed into the fixing screw on the underside of the clip-on keel. The first and second nuts together limit the position of the clip-on keel, thus fixing it in place. However, this process has the following problem: After screwing the first nut into each of the fixing screws, the height of each of the first nuts needs to be adjusted. To ensure the end faces are level, current methods rely on rough adjustments by construction workers based on their sense of touch. This manual adjustment is prone to errors and difficult to control, easily leading to problems such as height differences and horizontal misalignment of the keel. Furthermore, the installation of clip-on keels involves manual handling, holding the keel by hand and attaching it to the fixing rods. Positioning each keel requires the coordinated efforts of 2-3 construction workers (measuring, holding the keel, and fixing), and repeated measurements and adjustments are necessary. This inefficiency is particularly pronounced in large-area ceiling construction, severely impacting the overall construction progress.

[0004] Based on the above problems, the applicant of this application requests the design of an adjustable positioning device for the ceiling joists in interior decoration. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable positioning device for ceiling joists in interior decoration, so as to solve the technical problems of large horizontal adjustment error of nuts during the installation of clip-type joists, and low efficiency due to the need for multiple people to cooperate in the installation of joists.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an adjustable ceiling joist positioning device for interior decoration, characterized in that it comprises: First frame erection; The second support frame is located on one side of the first support frame; The leveling mechanism is mounted on the first and second uprights; The feeding mechanism is rotatably mounted on the leveling mechanism and is used to place bolts and clip-on keel; The leveling mechanism includes: The first L-shaped sleeve plate is slidably mounted on the first upright frame; The second L-shaped sleeve plate is slidably mounted on the second upright frame; The mating assembly is rotatably mounted on the first L-shaped sleeve plate and the second L-shaped sleeve plate to clamp the fixing screw on the top plate. When the fixing screw is clamped, the mating assembly forms a plane to limit the first screw nut that is screwed in. The lifting column is movably mounted on the first L-shaped sleeve plate and connected to the mating assembly to drive the mating assembly to rotate, so that the mating assembly clamps the fixed lead screw.

[0007] In one possible implementation, based on the above technical solutions, the mating assembly includes a first mating member and a second mating member. One end of both the first and second mating members is rotatably connected to a first upright plate on the first L-shaped sleeve, and the other end of both is rotatably connected to a second upright plate on the second L-shaped sleeve. The first and second mating members are provided with an inner cavity, and an abutment is provided within the inner cavity to adapt to different fixing screws. A first top spring is provided at the bottom end of the abutment and on the bottom wall of the inner cavity. Furthermore, gears are fixedly provided at the ends of the first and second mating members that are connected to the first L-shaped sleeve.

[0008] In one possible implementation, based on the above technical solution, a lifting hole is provided in the middle of the first L-shaped sleeve plate, the lifting column is disposed in the lifting hole and located between the first mating member and the second mating member, and the lifting column is provided with meshing teeth on both sides, the meshing teeth on both sides are respectively hinged to the gear on the first mating member and the gear on the second mating member, so that when the lifting column is raised or lowered, it can simultaneously drive the first mating member and the second mating member to rotate.

[0009] In one possible implementation, based on the above technical solutions, a first lifter is fixedly installed on one side of the first support frame, and a connecting body is fixedly connected to the output end of the first lifter. The interior of the lifting column is hollow, and a through-hole is opened in the bottom wall of the lifting column. The end of the connecting body passes through the through-hole and is connected to a baffle. A second top spring is provided between the baffle and the bottom wall of the lifting column.

[0010] In one possible implementation, in conjunction with the above technical solutions, a limiting plate is also provided on one side of the lifting column. When the output end of the first lifter descends, it drives the lifting column to descend, thereby driving the first mating component and the second mating component to assemble. Subsequently, the limiting plate is assembled by the first L-shaped sleeve plate to achieve the limiting of the lifting column.

[0011] In one possible implementation, based on the above technical solutions, slide rails are provided on the side walls of the first and second uprights, and sliders are provided at corresponding positions of the first and second L-shaped sleeves. The sliders are located inside the slide rails, and motors are provided on both the first and second uprights. A lead screw is fixed to the output end of the motor, and the lead screw passes through and is threaded to the first or second L-shaped sleeve to drive the first or second L-shaped sleeve to rise and fall.

[0012] In one possible implementation, based on the above technical solutions, the feeding mechanism includes a rotating rod, a first storage box hinged to the rotating rod via a first connecting rod, the first storage box having an opening at the top for placing construction supplies; a second storage box hinged to the rotating rod via a second connecting rod for placing a small amount of the card-type keel, the second storage box having a top wall, and a closed cover hinged to the top wall.

[0013] In one possible implementation, based on the above technical solutions, the end of the rotating rod is fitted with the first L-shaped sleeve plate and has a first arc groove. A first positioning plate is connected to the output end of the first lifter. A pull rope is fixed in the first arc groove. After the pull rope wraps around the first arc groove several times, it is fixed to the first positioning plate. When the output end of the first lifter descends, the rotating rod can be rotated by pulling the pull rope. The other end of the rotating rod is fitted with the second L-shaped sleeve plate and has a second arc groove. A second positioning plate is provided on the second L-shaped sleeve plate. An elastic rope is fixed in the second arc groove. After the elastic rope wraps around the second arc groove several times, it is fixed to the second positioning plate to pull the rotating rod to reset.

[0014] In one possible implementation, based on the above technical solutions, the top wall of the second storage box is provided with at least two clamping components. The clamping components include a lifting cylinder, a clamping cylinder, a first clamping plate, and a second clamping plate. The lifting cylinder is fixed to the top wall of the second storage box, and the clamping cylinder is fixed to the end of the lifting cylinder to be inserted into the slot of the clip-on keel. The first clamping plate is fixed to the end of the lifting cylinder, and a clamping groove is opened at the other end of the lifting cylinder. The second clamping plate is disposed in the clamping groove, and a tension spring is fixed between the first clamping plate and the second clamping plate.

[0015] In one possible implementation, based on the above technical solutions, the lifting cylinder includes a first lifting cylinder, a second lifting cylinder, a top block, and a third top spring. The second lifting cylinder is located inside the first lifting cylinder. The outer surface of the first lifting cylinder has a first opening, a second opening, and a third opening. The first opening communicates with the second opening and the third opening. The top block is located on one side of the bottom end of the second lifting cylinder. The third top spring is located between the bottom wall of the top block and the bottom wall of the first lifting cylinder. A locking block is also connected to the top block, and the locking block is locked into the second opening or the third opening. By setting the lifting cylinder, the clip-type keel can be pushed into the fixing screw, and the clip-type keel can be kept horizontally fixed.

[0016] The advantages of the adjustable ceiling keel positioning device provided by this invention are as follows: Compared with the prior art, this invention uses a first and second upright as a support base, coupled with a leveling mechanism that is raised and lowered on the upright. The leveling mechanism's mating component clamps the fixing screws on the ceiling plate and forms a horizontal limiting plane, accurately limiting the height and level of the first screwed-in nut. This completely solves the problem of large horizontal errors when manually adjusting the nuts, ensuring that all nuts on the fixing screws are on the same horizontal plane. Simultaneously, a rotatable feeding mechanism is provided on the leveling mechanism, which can hold construction consumables such as bolts and clip-on keels, and can also fix the clip-on keels through the clamping component and accurately push them into the fixing screws. This allows a single person to complete the keel positioning and installation without the need for multiple people to cooperate, significantly improving construction efficiency. Furthermore, the mating component in the device is flexibly equipped with abutment parts, which can adapt to fixing screws of different specifications. The overall device has strong adaptability and practicality, effectively reducing construction labor costs and improving the overall quality of ceiling construction. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0026] The present invention will now describe an adjustable ceiling joist positioning device for interior decoration.

[0027] like Figures 1 to 9 As shown, the present invention provides an adjustable ceiling joist positioning device for interior decoration, including a first support frame 100, a second support frame 200, a leveling mechanism 300, and a feeding mechanism 400; the second support frame 200 is located on one side of the first support frame 100 and is arranged parallel to the first support frame 100 to form the overall support frame of the device; the leveling mechanism 300 is raised and lowered on the first support frame 100 and the second support frame 200 to realize the clamping of the fixing screw 710 and the horizontal limit leveling of the nut; the feeding mechanism 400 is rotatably mounted on the leveling mechanism 300 to place nuts and construction consumables such as clip-on joists 800, and can rotate with the movement of the leveling mechanism 300 to facilitate construction personnel to pick up materials and install clip-on joists 800.

[0028] like Figure 2 and Figure 3As shown, the leveling mechanism 300 includes a first L-shaped sleeve 310, a second L-shaped sleeve 320, a mating assembly 330, and a lifting column 340. The first L-shaped sleeve 310 is slidably mounted on the first upright 100, and the second L-shaped sleeve 320 is slidably mounted on the second upright 200, and the two rise and fall synchronously. The mating assembly 330 is rotatably mounted on the first L-shaped sleeve 310 and the second L-shaped sleeve 320. Its core function is to clamp the fixing screw 710 on the top plate 700. When the fixing screw 710 is clamped, the lower end face of the mating assembly 330 forms a horizontal limiting plane to limit the height of the first screw-in nut, ensuring that the end face of the nut is at a preset horizontal plane. The lifting column 340 is movably mounted on the first L-shaped sleeve 310 and connected to the mating assembly 330 to drive the mating assembly 330 to open and rotate, so that the mating assembly 330 can clamp the fixing screw 710.

[0029] like Figure 2 and Figure 3 As shown, in a specific embodiment of the adjustable ceiling joist positioning device provided in this invention, the mating component 330 includes a first mating member 331 and a second mating member 332. One end of the first mating member 331 and the second mating member 332 are rotatably connected to the first vertical plate 313 on the first L-shaped sleeve plate 310, and the other end is rotatably connected to the second vertical plate 321 on the second L-shaped sleeve plate 320. The two can open and close synchronously to form a clamping structure. Both the clamping ends of the first mating member 331 and the second mating member 332 are provided with an inner cavity 333. An abutment member 334 is provided within the inner cavity 333 for limiting movement. The abutment member 334 can move slightly within the cavity to adapt to fixing screws 710 of different diameters, improving the versatility of the device. A first top spring (not shown in the attached diagram) is provided at the bottom end of the abutment member 334 and on the bottom wall of the inner cavity 333. The first top spring provides elastic support for the abutment member 334, allowing it to tightly fit against the outer wall of the fixing screw 710, ensuring clamping stability. When the first mating member 331 and the second mating member 332 are joined together, their clamping surfaces can clamp the fixing screw 710 on the top plate 700, while simultaneously providing a horizontal limit to the first screw-in nut, ensuring that the nuts on all fixing screws 710 are on the same horizontal plane. Furthermore, gears 335 are fixedly provided at the ends of the first mating parts 331 and the second mating parts 332 that are connected to the first L-shaped sleeve plate 310, providing a basis for transmission and engagement.

[0030] like Figure 3 and Figure 5As shown, a lifting hole 311 is further provided in the middle of the first L-shaped sleeve plate 310. The lifting column 340 is located in the lifting hole 311 and between the first mating member 331 and the second mating member 332. The lifting column 340 has meshing teeth 341 on both sides, which mesh with the gears 335 on the first mating member 331 and the second mating member 332 respectively, forming a gear and rack transmission structure. When the lifting column 340 moves vertically up and down in the lifting hole 311, the meshing action of the meshing teeth 341 and the gears 335 can simultaneously drive the first mating member 331 and the second mating member 332 to rotate synchronously, realizing the opening and closing of the mating assembly 330. The operation is convenient and the transmission is precise.

[0031] like Figure 1 and Figure 5 As shown in a specific embodiment of the present invention, a first lifter 500 is fixedly installed on one side of the first support frame 100. The first lifter 500 can be a linear drive component such as an electric push rod or a hydraulic cylinder, and its output end is fixedly connected to a connecting body 510. The interior of the lifting column 340 is hollow, and a through-hole is opened in the bottom wall. The end of the connecting body 510 passes through the through-hole and is connected to a baffle 520. A second top spring 530 is provided between the baffle 520 and the bottom wall of the lifting column 340. This structural design allows the second top spring 530 to provide cushioning when the first lifter 500 drives the lifting column 340 to descend, avoiding damage caused by hard contact between the mating assembly 330 and the fixed lead screw 710; at the same time, during resetting, the elastic force of the second top spring 530 can assist the lifting column 340 to rise, ensuring smooth transmission.

[0032] like Figure 5 As shown, in addition, a limit plate 342 is provided on one side of the lifting column 340. When the output end of the first lifter 500 descends, it drives the lifting column 340 to descend, thereby driving the first mating component 331 and the second mating component 332 to assemble into a horizontal plane and clamp the fixing screw 710. The limit plate 342 will then abut against the side wall of the first L-shaped sleeve 310, thereby achieving vertical limitation of the lifting column 340 and preventing it from continuing to descend and causing the mating component 330 to be over-clamped, ensuring that the limiting plane formed by the mating component 330 is always in a horizontal state.

[0033] like Figure 1 and Figure 5As shown, in a specific embodiment of the present invention, slide rails 110 are provided on both side walls of the first support 100 and the second support 200. Slider blocks 312 are provided at corresponding positions of the first L-shaped sleeve plate 310 and the second L-shaped sleeve plate 320. The sliders 312 are slidably disposed within the slide rails 110, forming a sliding guide structure to ensure the verticality and synchronicity of the first L-shaped sleeve plate 310 and the second L-shaped sleeve plate 320 during lifting. Furthermore, motors 120 are provided on both the first support 100 and the second support 200. A lead screw 130 is fixed to the output end of the motor 120. The lead screw 130 passes through and is threadedly connected to the first L-shaped sleeve plate 310 or the second L-shaped sleeve plate 320, forming a transmission structure. When the motors 120 on both sides are started simultaneously, the lead screw 130 rotates, driving the first L-shaped sleeve plate 310 and the second L-shaped sleeve plate 320 to rise and fall vertically synchronously along the slide rails 110, thereby achieving precise adjustment of the overall height of the leveling mechanism 300 to adapt to the construction needs of different ceiling heights.

[0034] like Figure 1 and Figure 8 As shown, in a specific embodiment of the present invention, the feeding mechanism 400 includes a rotating rod 410, which is transversely inserted and rotatably connected to a first L-shaped sleeve plate 310 and a second L-shaped sleeve plate 320. A first storage box 420 is hinged to the rotating rod 410 via a first connecting rod 421. The first storage box 420 has an opening at the top for storing construction supplies such as nuts, bolts, and wrenches, making it convenient for construction personnel to access them at any time. A second storage box 430 is hinged to the rotating rod 410 via a second connecting rod 431 for storing a small number of clip-on keels to be installed. The second storage box 430 has a top wall, on which a sealing cover 432 is hinged to prevent the clip-on keels 800 from falling off during transportation and installation. The sealing cover 432 has a handle for easy opening and closing.

[0035] like Figures 6 to 8As shown, further, the end of the rotating rod 410 is fitted with a first L-shaped sleeve plate 310 and has a first arc groove 411. The output end of the first lifter 500 is connected to a first positioning plate 540. A pull rope 550 is fixed in the first arc groove 411. After the pull rope 550 is wrapped around the first arc groove 411 several times, it is fixed to the first positioning plate 540. When the output end of the first lifter 500 descends, it will pull the rotating rod 410 to rotate through the pull rope 550, thereby driving the second storage box 430 to rotate to a position close to the fixing screw 710, which is convenient for keel installation. The other end of the rotating rod 410 is fitted with a second L-shaped sleeve plate 320 and has a second arc groove 412. A second positioning plate 600 is provided on the second L-shaped sleeve plate 320. An elastic rope 610 is fixed in the second arc groove 412. After the elastic rope 610 is wrapped around the second arc groove 412 several times, it is fixed to the second positioning plate 600. When the output end of the first elevator 500 rises and resets, the rebound force of the elastic rope 610 can pull the rotating rod 410 to rotate in the opposite direction and reset, driving the second storage box 430 back to the initial position, thus realizing the automatic reset of the feeding mechanism 400.

[0036] like Figure 8 and Figure 9 As shown, in a specific embodiment of the present invention, at least two clamping components 440 are provided on the top wall of the second storage box 430. The clamping components 440 are arranged along the keel installation direction to ensure the clamping stability of the card keel 800. The clamping assembly 440 includes a lifting cylinder 441, a clamping cylinder 442, a first clamping plate 443, and a second clamping plate 444. The lifting cylinder 441 is fixed to the top wall of the second storage box 430. The clamping cylinder 442 is fixed to the end of the lifting cylinder 441 and is used to snap into the slot of the clip-on keel 800 to achieve the initial positioning of the clip-on keel 800. The first clamping plate 443 is fixed to the end of the lifting cylinder 441. A clamping groove is opened at the other end of the lifting cylinder 441. The second clamping plate 444 is slidably disposed in the clamping groove. A tension spring 445 is fixed between the first clamping plate 443 and the second clamping plate 444. The tension of the tension spring 445 makes the first clamping plate 443 and the second clamping plate 444 tightly clamp the two sides of the clip-on keel 800 to prevent the clip-on keel 800 from shifting during installation.

[0037] like Figure 9As shown, the lifting cylinder 441 includes a first lifting cylinder 4411, a second lifting cylinder 4412, a top block 4413, and a third top spring 4414. The second lifting cylinder 4412 is slidably disposed within the first lifting cylinder 4411 to achieve length adjustment of the lifting cylinder 441. The outer surface of the first lifting cylinder 4411 is provided with a first opening 44111, a second opening 44112, and a third opening 44113. The first opening 44111 and the second opening 44112 and the third opening 44113 are connected. The top block 4413 is located on one side of the bottom end of the second lifting cylinder 4412, and the third top spring 4414 is located between the bottom wall of the top block 4413 and the bottom wall of the first lifting cylinder 4411, providing elastic support for the lifting of the second lifting cylinder 4412. A locking block 4415 is also connected to the top block 4413. The locking block 4415 can slide along the first opening 44111 and lock into the second opening 44112 or the third opening 44113, thereby fixing the extension length of the second lifting cylinder 4412. By adjusting the length of the lifting cylinder 441, the clip-type keel 800 can be precisely pushed into the fixing screw 710, keeping the clip-type keel 800 horizontally fixed, eliminating the need for manual handling and enabling convenient single-person installation.

[0038] Equipment construction and usage process Device positioning: Place the first upright 100 and the second upright 200 on both sides of the fixing screw 710 of the top plate 700, and adjust the device position so that the mating component 330 of the leveling mechanism 300 is aligned with the fixing screw 710. Height adjustment of leveling mechanism 300: Start the motor 120 on the first upright 100 and the second upright 200, and drive the first L-shaped sleeve 310 and the second L-shaped sleeve 320 to rise and fall through the lead screw 130, so as to adjust the mating component 330 to the preset nut installation height; Fixed screw 710 clamping: The first lifting device 500 is activated, and its output end descends, causing the lifting column 340 to move down. Through the meshing of the meshing teeth 341 and the gear 335, the first mating part 331 and the second mating part 332 are driven to assemble. The abutment part 334 is tightly attached to the outer wall of the fixed screw 710 under the action of the first top spring, thus completing the clamping. At this time, the lower end face of the mating assembly 330 forms a horizontal limiting plane. Nut positioning installation: Screw the first nut into the fixing screw 710 until the upper end face of the nut abuts against the horizontal limiting plane of the mating component 330 to complete the precise horizontal positioning of the nut. Complete the installation of nuts on all fixing screws 710 in sequence.
