Description
Technical Field
[0001] This invention relates to the field of hanging and placing devices for interior design and planning, and particularly to a multi-purpose hanging and placing device for interior design and planning. Background Technology
[0002] Interior design is based on the building's usage, environment, and relevant standards. It utilizes material and technical means and architectural design principles to create a functional and aesthetically pleasing interior environment that meets people's material and spiritual needs. Hanging designs are commonly seen in modern home decoration styles. Common examples include hanging TV cabinets, hanging bathroom vanities, and hanging toilets. This design is not only aesthetically pleasing and practical but also saves a lot of interior space. It breaks the traditional design principle that all furniture is supported by the ground. Therefore, hanging designs require the use of appropriate hanging devices.
[0003] However, current hanging devices often use expansion bolts to fix brackets to walls or ceilings for suspending items. But because ceilings and walls can withstand different amounts of weight, brackets with heavy loads can easily loosen and detach from the fixed base due to vibration or shallow insertion depth when connected to the wall or ceiling, causing the load to fall and creating a safety hazard.

[0007] Optionally, the guide post is provided in four places, and the four guide posts are fixedly connected to the top surface of the base in a ring array. The guide post has a longitudinal groove inside, and a bracket is slidably connected inside the longitudinal groove. The bracket has an L-shaped structure, and a collar is installed on the side of the bracket away from the guide post. The collar is sleeved on the outer side of the limiting drill.
[0008] Optionally, a projector is installed on the bottom end face of the limiting rod. The projector is used to project downwards at a height of [height] above the ground. A base body is fixedly connected to the bottom end face of the base. The base body is a frame structure. A motor A is installed on the right side of the base body, and a screw A is installed on the left side of the motor A. The motor A is used to drive the screw A to slide.

[0012] Beneficial effects
[0013] According to an embodiment of the present invention, the placement device, compared with the conventional method, drives the drive gear to rotate by starting the motor C mounted on the collar, and through the rotation of the limiting drill, it drives the limiting rod on the tilted side to rotate through the transmission connection between pulley A and belt B, and further through the meshing transmission of transmission gear A and transmission gear B, and indirectly through the friction transmission of pulley B and belt B, thereby automatically performing a further limiting and fixing operation on the base. This achieves the purpose of automatically replenishing and assembling operations according to different tilt conditions of the base, effectively ensuring that the suspended object will not fall due to loose installation during suspension.
[0014] Furthermore, in this invention, as the limiting rod extends deeper to limit the base, four pressure sensors installed on the top surface of the base will also sense pressure as the base approaches the fixed base surface. When the pressure values sensed by the four pressure sensors installed in the base are mismatched, the projector installed on the bottom side of the limiting rod will project the corresponding image downwards onto the ground to indicate to the installer that the current base assembly is not up to standard. This continues until the pressure value detected by the pressure sensor installed on the top of the base is constant, indicating that the current installation degree of the base is perpendicular to the base surface, thus achieving a more practical purpose.
[0015] In this invention, when it is necessary to limit and fix a suspended object, the item or container to be suspended can be placed inside the two movable seats installed in the base. Simultaneously, the motor A installed on the outside of the base is started to drive the screw A to rotate. Through the transmission connection between the screw A and the movable seats, the two movable seats are simultaneously driven to move inward to clamp the item to be limited. Then, the pump installed on the outside of the movable seats is started to inflate the limiting airbag installed on the inside of the movable seats to further flexibly limit the item in the movable seats, so as to achieve the purpose of rapid assembly of items of different specifications.

[0031] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.
[0032] Example: Please refer to Figures 1 to 10 :
[0033] This invention proposes a multi-purpose hanging device for interior design planning, comprising: a base 1, the main body of which is a rectangular box structure, and pressure sensors 2 are installed in a circular array on the top surface of the base 1. The pressure sensors 2 installed on the top surface of the base 1 are used to detect the installation strength of the base 1 from the mounting base surface. Mounting holes are provided at the four corners of the interior of the base 1, and limit rods 3 are installed inside the four mounting holes. A guide ring 29 is installed on the outside of the drive shaft 28, and the guide ring 29 is connected to the bracket 21. An extension shaft 30 is inserted into the drive shaft 28. A drive gear B31 is mounted on the top of the extension shaft 30, and the drive gear B31 meshes with the drive gear A27. Pulleys B32 are sleeved on the outer sides of both the drive shaft 28 and the limiting rod 3. The pulley B32 located outside the limiting rod 3 has a threaded hole inside, and belts B33 are mounted on the outer sides of both pulleys B32. A guide frame 24 is fixedly connected to the outer side of the bracket 21. A groove is formed inside the guide frame 24, and an electric motor is installed inside the groove. The guide frame 24 is internally slidably connected to the push rod 25 and the guide rod 24, and the movable platform 26 is connected to the electric push rod 25 and is moved by the electric push rod 25. The bottom end of the pulley A22 installed at the top of the movable platform 26 is coaxially mounted with a transmission gear A27. The top surface of the base 1 is mounted with a transmission shaft 28. When it is necessary to limit and fix the suspended object, the item or container to be suspended can be placed inside the two movable seats 8 installed in the base 5, and the movable seats 8 installed in the base 1 can be activated simultaneously. 5. The outer motor A6 drives the screw A7 to rotate, and through the transmission connection between the screw A7 and the movable seat 8, it synchronously drives the two movable seats 8 to move inward at the same time to clamp the items that need to be limited. Then, the pump 10 installed on the outer side of the movable seat 8 is started synchronously to inflate the limiting airbag 9 installed on the inner side of the movable seat 8 to further flexibly limit the items in the movable seat 8, so as to achieve the purpose of rapid assembly of items of different specifications.
[0034] Furthermore, according to embodiments of the present invention, such as Figures 1-3As shown, a projector 4 is installed on the bottom surface of the limiting rod 3. The projector 4 is used to project downwards at a height of [height missing] from the ground. A base 5 is fixedly connected to the bottom surface of the base 1. The base 5 is a frame structure, and a motor A6 is installed on the right side of the base 5. A screw A7 is installed on the left side of the motor A6. The motor A6 is used to drive the screw A7 to slide. Two movable seats 8 are slidably connected to each other on the inner side of the base 5. The interior of each movable seat 8 is provided with screw holes that match the screw A7, and the screw holes in the two movable seats 8 have opposite thread directions. Two limiting airbags 9 are installed in a straight array on the outer side of each movable seat 8. A pump 10 is installed on the rear side of the movable seat 8. The pump 10 is used to supply air to the limiting airbags 9. When the limiting drill 13 penetrates into the fixed base surface, the assembly status of the base 1 can be monitored synchronously by the pressure sensor 2 installed on the base 1. After the limiting drill 13 is fixed, the limiting rod 3 installed in the four corner mounting holes of the base 1 can be rotated to make the limiting rod 3 drill into the interior of the base surface to reinforce and fix the base 1. As the limiting rod 3 goes deeper to limit the base 1, the four pressure sensors 2 installed on the top surface of the base 1 will also sense the pressure as the base 1 gets closer to the fixed base surface. When the pressure values sensed by the four pressure sensors 2 installed in the base 1 are mismatched, the projector 4 installed on the bottom side of the limiting rod 3 will project the corresponding image downwards onto the ground to indicate to the installer that the current base 1 is not properly assembled. Until the pressure value detected by the pressure sensor 2 installed on the top of the base 1 is constant, it indicates that the current installation degree of the base 1 is perpendicular to the base surface, thus achieving a more practical purpose.
[0035] Furthermore, according to embodiments of the present invention, such as Figures 1-6As shown, the movable seat 8, the limiting airbag 9, and the pump 10 together form a limiting structure. A motor B11 is installed at the bottom of the movable seat 8, and a rotating shaft is installed at the top of the motor B11. A rubber wheel 12 is installed on the outer side of the rotating shaft at the top of the motor B11. The motor B11 and the rubber wheel 12 together form a driving and conveying structure for materials. A guide post 17 is fixedly connected inside the base 1. There are four guide posts 17, arranged in a circular array and fixedly connected to the top surface of the base 1. A longitudinal groove is opened inside the guide post 17, and a bracket 21 is slidably connected inside the longitudinal groove. The bracket 21 has an L-shaped structure, and a collar 20 is installed on the side of the bracket 21 away from the guide post 17. The limit drill 13 is connected to the outside of the limit drill 13. The motor C14 installed on the collar 20 drives the drive gear 15 to rotate. The rotation of the limit drill 13 synchronously drives the limit rod 3 on the tilted side to rotate through the transmission connection between the pulley A22 and the belt B33, and further through the meshing transmission of the transmission gear A27 and the transmission gear B31, and indirectly through the friction transmission between the pulley B32 and the belt B33. This automatically limits and fixes the base 1, thereby achieving the purpose of automated replenishment and assembly operation according to the different tilt conditions of the base 1. This effectively ensures that the suspended object will not fall due to loose installation when suspended.
[0036] Furthermore, according to embodiments of the present invention, such as Figures 1-10 As shown, a motor C14 is installed at the top of the collar 20, and a drive gear 15 is installed at the top of the motor C14. A driven gear 16 is installed on the outer circumferential surface of the limiting drill 13. The drive gear 15 meshes with the driven gear 16. A motor D18 is installed inside the longitudinal groove opened in the guide post 17. A screw B19 is installed at the top of the motor D18. The motor D18 is used to drive the screw B19 to rotate. The screw B19 is connected to the bracket 21 for transmission. The motor D18 and the screw B19 together form the transmission structure for the bracket 21. A pulley A22 is installed on the outer side of the limiting drill 13. There are three pulleys A22. The other two pulleys A22 are installed on the moving table 26 and the guide frame 24 respectively. A belt A23 is installed on the outer side of the three pulleys A22. The pulleys A22 and the belt A23 together form the transmission structure.
[0037] The specific usage and function of this embodiment: In this invention, when it is necessary to hang and place items during the interior design planning process, the base 1 can be placed on the base surface that needs to be fixed and limited, and the base 1 can be kept perpendicular to the base surface. Then, the motor C14 installed on the collar 20 is started to drive the drive gear 15 to rotate. Simultaneously, the meshing transmission between the drive gear 15 and the driven gear 16 further drives the limit drill 13 installed in the collar 20 to rotate, so as to further enlarge the hole pre-opened on the base surface.
[0038] Simultaneously, the screw B19 can be rotated by starting the motor D18 installed in the guide post 17, and the screw B19 and the bracket 21 can be driven by the limiting ring 20 through the transmission connection between the screw B19 and the bracket 21, so that the limiting drill 13 can be driven by the rotation of the motor C14 to enter the pre-opened hole to perform the initial positioning and fixing operation of the base 1.
[0039] As the limiting drill 13 penetrates into the fixed base surface, the pressure sensor 2 installed on the base 1 can simultaneously monitor the assembly status of the base 1. Simultaneously, after the limiting drill 13 is fixed, the limiting rod 3 installed in the four corner mounting holes of the base 1 can be rotated to drill into the base surface, reinforcing the base 1. As the limiting rod 3 penetrates and limits the base 1, the four pressure sensors 2 installed on the top surface of the base 1 will sense pressure as the base 1 approaches the fixed base surface. When the pressure values sensed by the four pressure sensors 2 in the base 1 are mismatched, the projector 4 installed on the bottom side of the limiting rod 3 will project a corresponding image onto the ground to indicate to the installer that the base 1 assembly is not up to standard. This continues until the pressure value detected by the pressure sensor 2 at the top of the base 1 is constant, indicating that the base 1 is perpendicular to the base surface, thus achieving a more practical purpose.
[0040] When it is necessary to limit and fix the suspended object, the item or container to be suspended can be placed inside the two movable seats 8 installed in the seat body 5. At the same time, the motor A6 installed on the outside of the seat body 5 is started to drive the screw A7 to rotate. Through the transmission connection between the screw A7 and the movable seat 8, the two movable seats 8 are driven to move inward at the same time to clamp the item to be limited. Then, the pump 10 installed on the outside of the movable seat 8 is started to inflate the limiting airbag 9 installed on the inside of the movable seat 8 to further flexibly limit the item in the movable seat 8, so as to achieve the purpose of quick assembly of items of different specifications.
[0041] When the items in the movable seat 8 need to be aligned and moved, the motor B11 installed on the bottom side of the movable seat 8 can be started to drive the rubber wheel 12 installed in the movable seat 8 to rotate. The rubber wheel 12 contacts the items to make further fine adjustments to the items that have been suspended. This allows personnel to quickly correct the items in the movable seat 8 without having to climb up and down, thereby improving assembly efficiency.
[0042] When the pressure sensor 2 installed at the top of the base 1 detects that the assembly of the base 1 is loose or tilted, the motor C14 installed on the collar 20 can be started simultaneously to drive the drive gear 15 to rotate, and the screw B19 can be driven to rotate simultaneously through the motor D18, so that the limiting drill 13 can be further actively inserted into the interior of the base surface to perform further limiting and fixing operations on the base 1, thereby effectively preventing the base 1 from falling.
[0043] Furthermore, when the data from a single pressure sensor 2 installed at the top of the base 1 is inconsistent with the data from other pressure sensors 2, the electric push rod 25 installed in the guide frame 24 can be activated simultaneously to move the moving stage 26 together with the transmission gear A27 toward one side of the transmission gear B31 until the transmission gear A27 and the transmission gear B31 are engaged. Then, the motor C14 installed on the collar 20 is activated to drive the drive gear 15 to rotate. The rotation of the limit drill 13 is synchronized with the transmission connection between the pulley A22 and the belt B33. The transmission gears A27 and B31 are engaged, and the friction transmission between the pulley B32 and the belt B33 is used to drive the limit rod 3 on the tilted side to rotate, so as to automatically perform further limit and fixation operations on the base 1. This achieves the purpose of automated replenishment and assembly operations according to different tilt conditions of the base 1, effectively ensuring that the suspended object will not fall due to loose installation.
[0044] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.
[0045] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention, which is determined by the appended claims.
