Description

Technical Field

[0001] This application relates to the field of stent technology, and in particular to an adjustable stent. Background Technology

[0002] Currently, a support is a structural device used to support, fix or bear objects. It is widely used in many fields such as industrial production, daily life, and scientific research experiments. Its core function is to provide stable force support for the supported object through its own structural design, to ensure that the object remains stable in a specific position, or to adjust parameters such as position and angle.

[0003] Regarding the aforementioned technologies, existing methods of welding or fixing the metal rods of the support frame through small holes result in extremely poor flexibility. When the spacing between the metal rods needs to be adjusted according to the size of the object to be magnetized, the welded metal rods must be destructively removed and re-welded, which not only consumes a lot of time and manpower but may also damage the lower plate. At the same time, without incorporating more convenient and precise structures to maintain consistent height for the four corner fixation points, relying solely on screw and nut connections makes it difficult to ensure that the height of the four supports is completely uniform due to factors such as processing errors and uneven installation force. This can cause the upper and lower plates to tilt, making the supported object unstable and potentially leading to slippage and damage. Furthermore, the uneven force on the support frame in the tilted state will accelerate component wear over long-term use, shorten the lifespan of the support frame, and may also affect the accuracy of magnetization and other related operations, reducing the overall reliability of the equipment. Utility Model Content

[0004] The purpose of this application is to provide an adjustable bracket that has the advantages of flexible adjustment of the metal rod and high precision of electric lifting adjustment, thus solving the problems mentioned in the background art.

[0005] The adjustable bracket provided in this application adopts the following technical solution: it includes a lower plate, an upper plate, a height adjustment mechanism, and a flexible adjustment mechanism. The height adjustment mechanism includes an electric push rod fixedly installed on the top of the lower plate. Three fixed cylinders are fixedly connected to the top of the lower plate. A support rod is slidably connected inside the fixed cylinder. A magnetic block is fixedly connected to the top of the electric push rod and the top of the support rod. Four grooves are opened at the bottom of the upper plate, and the magnetic blocks are adapted to the grooves.

[0006] The flexible adjustment mechanism includes several circular holes on the top of the lower plate, with a metal rod inserted into the inside of each hole. Adsorption holes are provided on both sides of each hole, and several sets of magnetic balls are fixedly connected to the surface of the metal rod.

[0007] By adopting the above technical solution and setting up a height adjustment mechanism, when it is necessary to adjust the height between the upper and lower plates, the electric push rod is activated. The electric push rod extends or retracts, causing the connected support rod to slide within the fixed cylinder. Since both the top of the electric push rod and the top of the support rod are fixed with magnetic blocks, and the groove at the bottom of the upper plate matches the magnetic blocks, the magnetic blocks move with the movement of the electric push rod and the support rod, thereby causing the upper plate to rise or fall. When the desired height is reached, the electric push rod is deactivated, and the magnetic blocks and the groove are tightly attracted, achieving a stable fixation of the upper plate. The activation of the electric push rod achieves electric height adjustment, which is convenient and labor-saving, eliminating the need for laborious manual adjustment. The cooperation between the fixed cylinder and the support rod ensures stability during height adjustment, preventing the upper plate from wobbling. The attraction between the magnetic blocks and the groove enhances the firmness of the upper plate fixation. The purpose of this system is to provide a flexible adjustment mechanism. By selecting a suitable circular hole based on the size of the object to be supported, a metal rod is inserted. The magnetic balls on the surface of the metal rod attract the magnetic holes on both sides of the circular hole, initially fixing the metal rod within the hole. If the position of the metal rod needs adjustment, simply apply a certain force to pull it out and insert it into another circular hole. The attraction between the magnetic balls and the magnetic holes ensures that the metal rod is not easily dislodged during adjustment and remains stable after insertion. The cooperation between the circular holes and the metal rod allows for flexible adjustment of its position, adapting to support objects of different sizes. The attraction between the magnetic balls and the magnetic holes ensures the stability of the metal rod during use and facilitates its disassembly and reinstallation, improving the flexibility and versatility of the support. The metal rod position can be quickly adjusted without complicated operations.

[0008] Preferably, two V-shaped steel plates are inserted into the interior of the lower plate, and two silicone pads are fixedly connected to the bottom of the V-shaped steel plates.

[0009] By adopting the above technical solution and setting a V-shaped steel plate, the contact area between the lower plate and the external load-bearing surface is effectively reduced, which is conducive to heat dissipation. By setting a silicone pad, the anti-slip purpose is achieved, ensuring the stability of the bracket placement.

[0010] Preferably, the V-shaped steel plate is internally fixedly connected with two reinforcing rods.

[0011] By adopting the above technical solution and setting up reinforcing rods, the strength and rigidity of the V-shaped steel plate are enhanced.

[0012] Preferably, the interior of the lower plate and the interior of the V-shaped steel plate are provided with threaded holes, and a support screw is threaded into the interior of the threaded hole. One end of the support screw is fixedly connected to a retaining ring.

[0013] By adopting the above technical solution, and by setting threaded holes, support screws and fixing rings, it is possible to facilitate the replacement of V-shaped steel plates after they are damaged.

[0014] Preferably, handles are fixedly connected to both sides of the lower plate and both sides of the upper plate, and the surface of the handles is provided with an anti-slip layer.

[0015] By adopting the above technical solution and setting handles, the movement of the support can be made more convenient and labor-saving, facilitating the transfer of the support between different working positions. By setting anti-slip layers, safety during the movement is improved, preventing damage to the support or injury to personnel due to slipping.

[0016] Preferably, a storage box is fixedly connected to the side of the lower plate, and a level is snapped into the inside of the storage box.

[0017] By adopting the above technical solution and setting up a storage box, a dedicated storage space can be provided to facilitate the management and retrieval of the level. By setting up the level, users can quickly determine whether the support is level, avoiding instability of objects or affecting work accuracy due to the tilt of the support, thus improving the accuracy and reliability of the support.

[0018] Preferably, a measuring ruler is fixedly connected to the side of the lower plate.

[0019] By adopting the above technical solution and setting a measuring ruler, it is possible to facilitate users to measure dimensions during use, improve the accuracy of metal rod position adjustment, ensure that objects can be placed accurately and stably on the support, and reduce problems such as unstable support caused by size misjudgment.

[0020] Preferably, both the surface of the lower plate and the surface of the upper plate are covered with rubber sleeves.

[0021] By adopting the above technical solution and setting rubber sleeves, the purpose of preventing the sharp parts of the upper and lower plates from causing injury to personnel's hands can be achieved.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This adjustable bracket features a height adjustment mechanism. When the height between the upper and lower plates needs adjustment, an electric actuator is activated. The actuator extends or retracts, causing a connected support rod to slide within a fixed cylinder. Since both the top of the electric actuator and the top of the support rod are fixed with magnetic blocks, and the groove on the bottom of the upper plate matches the magnetic blocks, the magnetic blocks move with the actuator and support rod, thus raising or lowering the upper plate. Once the desired height is reached, the electric actuator is deactivated, and the magnetic blocks adhere tightly to the groove, achieving a stable fixation of the upper plate. The electric actuator enables electric height adjustment, offering convenient and effortless operation without the need for manual adjustment. The cooperation between the fixed cylinder and the support rod ensures stability during height adjustment, preventing the upper plate from wobbling. The magnetic blocks' adhesion to the groove further enhances the stability of the upper plate. The purpose is to create a flexible adjustment mechanism that allows for the selection of appropriate circular holes based on the size of the object to be supported. A metal rod is inserted into the hole, and the magnetic balls on the surface of the rod attract the magnetic holes on both sides, initially fixing the rod within the hole. If the position of the rod needs adjustment, simply apply force to pull it out and insert it into another hole. The attraction between the magnetic balls and the magnetic holes ensures the rod is not easily dislodged during adjustment and remains stable after insertion. The cooperation between the circular holes and the metal rod allows for flexible adjustment of its position, adapting to support objects of different sizes. The attraction between the magnetic balls and the magnetic holes ensures the stability of the metal rod during use and facilitates its disassembly and reinstallation, improving the flexibility and versatility of the support. The rod's position can be quickly adjusted without complex operations. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: An adjustable support, as shown in the figure. Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a lower plate 1, an upper plate 2, a height adjustment mechanism 3, and a flexible adjustment mechanism 4. The height adjustment mechanism 3 includes an electric push rod 301 fixedly installed on the top of the lower plate 1. Three fixed cylinders 302 are fixedly connected to the top of the lower plate 1. A support rod 303 is slidably connected inside the fixed cylinders 302. A magnetic block 304 is fixedly connected to the top of the electric push rod 301 and the top of the support rod 303. Four grooves 305 are opened at the bottom of the upper plate 2. The magnetic block 304 is adapted to the grooves 305.

[0033] The flexible adjustment mechanism 4 includes several circular holes 401 on the top of the lower plate 1. A metal rod 402 is inserted into the inside of each circular hole 401. Adsorption holes 404 are provided on both sides of each circular hole 401. Several sets of magnetic balls 403 are fixedly connected to the surface of the metal rod 402. By setting the height adjustment mechanism 3, when it is necessary to adjust the height between the upper plate 2 and the lower plate 1, the electric push rod 301 is activated. The electric push rod 301 extends or retracts, causing the support rod 303 connected to it to slide within the fixed cylinder 302. Since magnetic blocks are fixed to the top of both the electric push rod 301 and the support rod 303, the mechanism is effective. 304, and the groove 305 at the bottom of the upper plate 2 is compatible with the magnetic block 304. The magnetic block 304 moves with the movement of the electric push rod 301 and the support rod 303, thereby driving the upper plate 2 to rise or fall. When the desired height is reached, the electric push rod 301 is turned off, and the magnetic block 304 and the groove 305 are tightly attracted, achieving a stable fixing effect for the upper plate 2. The start of the electric push rod 301 achieves electric height adjustment, which is convenient and labor-saving, eliminating the need for manual adjustment. The cooperation between the fixing cylinder 302 and the support rod 303 ensures stability during the height adjustment process and prevents the upper plate 2 from rising. The shaking effect of the plate 2 and the attraction between the magnetic block 304 and the groove 305 enhance the stability of the upper plate 2. By setting a flexible adjustment mechanism 4, a suitable circular hole 401 is selected according to the size of the object to be supported, and the metal rod 402 is inserted into it. The magnetic ball 403 on the surface of the metal rod 402 will attract each other to the attraction holes 404 on both sides of the circular hole 401, thus initially fixing the metal rod 402 within the circular hole 401. If the position of the metal rod 402 needs to be adjusted, simply apply a certain force to pull out the metal rod 402 and then insert it into another circular hole 401. The adsorption force between the magnetic ball 403 and the adsorption hole 404 ensures that the metal rod 402 is not easily dislodged during adjustment and remains stable after insertion. Due to the cooperation between the round hole 401 and the metal rod 402, the position of the metal rod 402 can be flexibly adjusted to support objects of different sizes. The adsorption effect between the magnetic ball 403 and the adsorption hole 404 ensures the stability of the metal rod 402 during use and facilitates the disassembly and reinstallation of the metal rod 402, improving the flexibility and versatility of the bracket. The position adjustment of the metal rod 402 can be quickly completed without complicated operations.

[0034] Please see Figure 1 The lower plate 1 has two V-shaped steel plates 5 inserted inside. The bottom of the V-shaped steel plates 5 is fixedly connected to two silicone pads 6. By setting the V-shaped steel plates 5, the contact area between the lower plate 1 and the external load-bearing surface is effectively reduced, which is conducive to heat dissipation. By setting the silicone pads 6, the anti-slip purpose is achieved, ensuring the stability of the bracket placement. The V-shaped steel plates 5 are fixedly connected to two reinforcing rods 7 inside. By setting the reinforcing rods 7, the strength and rigidity of the V-shaped steel plates 5 are enhanced.

[0035] Please see Figure 1 and Figure 5 The lower plate 1 and the V-shaped steel plate 5 have threaded holes 14 inside. The threaded holes 14 are threaded with support screws 15. One end of the support screws 15 is fixedly connected to a fixing ring 16. By setting the threaded holes 14, support screws 15 and fixing rings 16, it is possible to facilitate the replacement of the V-shaped steel plate 5 after it is damaged. The lower plate 1 and the upper plate 2 are fixedly connected with handles 8 on both sides. The surface of the handles 8 is provided with an anti-slip layer 9. By setting the handles 8, it is possible to make the movement of the bracket more convenient and labor-saving, and to facilitate the transfer of the bracket between different working positions. By setting the anti-slip layer 9, the safety during the movement is improved, and the bracket is prevented from being damaged or people injured due to slipping.

[0036] Please see Figure 1 A storage box 10 is fixedly connected to the side of the lower plate 1. A level 11 is snapped into the inside of the storage box 10. By setting up the storage box 10, a dedicated storage space can be provided to facilitate the management and retrieval of the level 11. By setting up the level 11, users can quickly determine whether the support is level, avoiding instability of objects or affecting work accuracy due to the tilt of the support, thus improving the accuracy and reliability of the support. A measuring ruler 12 is fixedly connected to the side of the lower plate 1. By setting up the measuring ruler 12, users can conveniently measure dimensions during use, improving the accuracy of the metal rod 402 position adjustment, ensuring that objects can be accurately and stably placed on the support, and reducing problems such as unstable support due to dimensional judgment errors. Rubber sleeves 13 are provided on the surface of the lower plate 1 and the surface of the upper plate 2. By setting up the rubber sleeves 13, the sharp parts of the upper plate 2 and the lower plate 1 can be used to prevent injury to the hands of personnel.

[0037] The implementation principle of this application embodiment is as follows: First, the upper plate 2 and the lower plate 1 are placed on a suitable external load-bearing surface with the help of the handle 8. The silicone pads 6 at the bottom of the two V-shaped steel plates 5 inserted inside the lower plate 1 are in contact with the load-bearing surface. The anti-slip properties of the silicone pads 6 are used to initially ensure the stability of the bracket placement. At the same time, the structure of the V-shaped steel plates 5 reduces the contact area between the lower plate 1 and the load-bearing surface, which prepares for heat dissipation during subsequent use.

[0038] Then, the magnetized object is placed on the lower plate 1, and the electric push rod 301 in the height adjustment mechanism 3 is activated. The electric push rod 301 extends or retracts, causing the support rod 303 connected to it to slide in the fixed cylinder 302. Since the magnetic block 304 at the top of the electric push rod 301 and the support rod 303 is adapted to the groove 305 at the bottom of the upper plate 2, the magnetic block 304 moves together, thereby causing the upper plate 2 to rise or fall until the desired height is reached. Then the electric push rod 301 is turned off, and the magnetic block 304 is tightly attracted to the groove 305, thus completing the height fixation of the upper plate 2.

[0039] Then, referring to the measuring ruler 12 on the side of the lower plate 1, select the appropriate position of the round hole 401 according to the size of the object, insert the metal rod 402 into the round hole 401, and the magnetic ball 403 on the surface of the metal rod 402 and the adsorption holes 404 on both sides of the round hole 401 attract each other to achieve the initial fixation of the metal rod 402. By adjusting the position and number of the metal rods 402, it can stably magnetize the object.

[0040] Next, take out the level 11 from the storage box 10 fixed to the side of the lower plate 1, place it on the surface of the upper plate 2 or the lower plate 1, and observe the position of the bubble in the level 11. If the bubble is not in the center, use the fixing ring 16 to rotate the V-shaped steel plate 5 and the support screw 15 in the threaded hole 14 inside the lower plate 1 to adjust the support state of the V-shaped steel plate 5 until the bubble in the level 11 is centered, ensuring that the bracket is in a horizontal state. Then put the level 11 back into the storage box 10.

[0041] Finally, personnel can perform processing operations on the magnetized object, and their hands can be protected with rubber sleeves 13 during the process.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
