Description

Technical Field

[0001] The present invention relates to the field of resin handicrafts, and particularly relates to a magnetic levitation resin handicraft and its preparation process. Background Art

[0002] Resin handicrafts are made of resin and cast into the desired shape through a mold. They are characterized by vivid images and beautiful shapes. In the production process, first, a silicone rubber mold is made according to the required shape. Then, resin is added with fillers and stirred evenly, and then formed through the mold. After the resin is cured, it is demolded to obtain the handicraft. Subsequently, repairs, coloring, etc. are carried out.

[0003] Most resin handicrafts are in a static state under normal conditions. Currently, there are also decorative structures using magnetic levitation technology to form a levitation state on the market. For example, Chinese Patent CN201620258359.3 discloses a magnetic levitation decorative set, including a base and a levitation bottom plate arranged above the base. The levitation bottom plate consists of a permanent magnet arranged in the center and a rubber mold arranged on the surface layer. At least one bonsai is arranged on the levitation bottom plate; the base includes an annular permanent magnet ring, at least three coils located at the center of the annular permanent magnet ring, and at least one power supply for supplying power to the coils to generate a magnetic field. The base is in a frustum shape.

[0004] However, most products need to be connected to a power supply and use the repulsive force between an electromagnet and a permanent magnet to make it in a levitation state. After accidental power failure, the permanent magnet will fall under the action of gravity, hitting the handicraft area below it, resulting in wear or damage to the appearance of the handicraft. Summary of the Invention

[0005] Therefore, the present invention provides a magnetic levitation resin handicraft and its preparation process, which solves the problem that the existing magnetic levitation handicrafts are prone to damage after sudden power failure.

[0006] To achieve the above object, the present invention is realized through the following technical solutions:

[0007] A magnetic levitation resin handicraft includes a handicraft main body made of resin. A magnetic levitation device is embedded at the end of the handicraft main body. The magnetic levitation device includes a base, an electromagnet embedded in the base, and a levitation body adapted to the electromagnet. A permanent magnet attracted by the electromagnet is embedded inside the levitation body. A telescopic rope assembly is arranged in the base. The telescopic rope assembly includes a rope reel, a winding spring installed in the rope reel, and a traction rope wound around the rope reel and connected to the winding spring. The free end of the traction rope is connected to the levitation body. The levitation body is located below the base under the combined action of the traction rope and the electromagnet.

[0008] The electromagnet is fixed on a rotating seat inside the base. A rotating mechanism for driving the rotating seat to revolve around the center of the base inside the base is connected to the rotating seat. The rotating mechanism includes a rotating motor, a driving gear mounted on the output shaft of the rotating motor, and a driven gear ring in transmission connection with the driving gear. The telescopic rope assembly and the rotating seat are fixed on the driven gear ring. The towing rope passes through the rotating seat and is connected to the floating body so that it is suspended at the center of the floating body.

[0009] Preferably, at least one L-shaped installation groove for installing the base is provided on the inner wall of the end of the handicraft main body, and a clamping block adapted to the installation groove is provided on the base.

[0010] Preferably, the floating body is a rotationally symmetric rotating body structure, and the permanent magnet is located at the geometric center of the floating body.

[0011] Preferably, the permanent magnet is eccentrically provided inside the floating body.

[0012] Preferably, a guiding groove is provided at the end of the handicraft main body, and a guiding ball adapted to the guiding groove is installed on the towing rope. When the driven gear ring rotates, the guiding ball slides in the guiding groove.

[0013] A preparation process for a magnetic levitation resin handicraft is characterized by comprising the following steps:

[0014] a. Making a silicone mold according to the shape of the resin handicraft, and an embedding cavity having the same outer shape as the base is formed on the obtained silicone mold;

[0015] b. Pouring unsaturated resin and fillers through the silicone mold, demolding after solidification and forming, to obtain a handicraft blank with the required shape; the fillers include conventional materials for resin casting such as curing agents and accelerators;

[0016] c. Placing a metal reinforcing bar for reinforcement at the lower opening of the corresponding position of the embedding cavity on the handicraft blank;

[0017] d. Supplementing resin materials at the position of the metal reinforcing bar to wrap the metal reinforcing bar and form a clamping end for fixing the base;

[0018] e. Grinding, trimming, coloring, and air-drying the product obtained in step c;

[0019] f. Installing the magnetic levitation device at the corresponding position of the embedding cavity on the product obtained in step d to obtain the magnetic levitation handicraft.

[0020] Preferably, in step d, manual cutting is further included at the wrapping position of the metal reinforcing bar to form an L-shaped installation groove for installing the base.

[0021] Preferably, in step d, manual cutting is further included at the wrapping position of the metal rib to form an annular guide groove structure.

[0022] By adopting the foregoing technical solutions, the beneficial effects of the present invention are as follows:

[0023] In terms of product structure, on the basis of the traditional magnetic levitation structure, a traction rope structure is added to the levitation body. Through the combined action with the electromagnet, the levitation effect of the levitation body is satisfied. The advantage of this dual force is that when the power is off, the traction rope can maintain the basic structure of the levitation body, preventing it from detaching from the entire product and avoiding the situation of falling and damage after power failure; and in cooperation with the traction rope, the optional range of the electromagnet model size is increased. When the levitation body is heavier, a model with a smaller magnetic force can also be selected. Firstly, since the electromagnet is buried in the handicraft, choosing a smaller size can reduce its overall heat generation, ensure the service life, and at the same time reduce the material cost; secondly, when the size of the entire handicraft is larger, the combined use of the electromagnet and the traction rope can also increase the design diversity of the levitation body. Its design includes the size and shape of the levitation body and the actions adapted to the traction rope, etc. In cooperation with the adjustable magnetic force of the electromagnet, it is different from the traditional structure. The levitation body can be designed to run on the designed track according to the design, realizing preset actions such as floating up and down, and the structure is more novel and diverse.

[0033] The following will combine specific embodiments to elaborate on the implementation manners of the present invention, so as to fully understand how the present invention applies technical means to solve technical problems and the implementation process of achieving technical effects, and implement accordingly. Embodiment 1

[0034] Reference Figure 1 And Figure 2 , a magnetic levitation resin handicraft, including a handicraft main body 100 made of resin. A magnetic levitation device is embedded at the end of the handicraft main body 100. The magnetic levitation device includes a base 1, an electromagnet 2 embedded in the base 1, and a suspension body 3 adapted to the electromagnet 2. A permanent magnet 31 attracted by the electromagnet 2 is embedded inside the suspension body 3. A telescopic rope assembly is provided inside the base 1. The telescopic rope assembly includes a rope reel 4, a winding spring installed inside the rope reel 4, and a traction rope 41 wound around the rope reel 4 and connected to the winding spring. The free end of the traction rope 41 is connected to the suspension body 3. The suspension body 3 is located below the base 1 under the combined action of the traction rope 41 and the electromagnet 2.

[0035] The electromagnet 2 is fixed on a rotating seat 21 inside the base 1. A rotating mechanism for driving it to revolve around the center of the base 1 inside the base 1 is connected to the rotating seat 21. The rotating mechanism includes a rotating motor 5, a driving gear 51 installed on the output shaft of the rotating motor 5, and a driven gear ring 52 in transmission connection with the driving gear 51. The telescopic rope assembly and the rotating seat 21 are fixed on the driven gear ring 52. The traction rope 41 passes through the rotating seat 21 and is connected to the suspension body 3 so as to be suspended at the center of the suspension body 3. Structurally, two L-shaped installation grooves 101 for installing the base 1 are provided on the inner wall of the end of the handicraft main body 100. A clamping block adapted to the installation groove 101 is provided on the base 1. During installation, the clamping block on the base 1 is inserted into the installation groove 101 and then rotated by a certain angle to be clamped inside.

[0036] Meanwhile, in order to ensure the structural strength of this position, metal rib strips 6 for strengthening structures are arranged on the peripheral side position of the clamping groove to avoid deformation due to insufficient strength here, which affects the appearance beauty of the handicraft.

[0037] In terms of product structure, on the basis of the traditional magnetic levitation structure, a traction rope 41 structure is added to the levitation body 3. Through the combined action with the electromagnet 2, the levitation effect of the levitation body 3 is satisfied. The advantage of this dual force is that when the power is off, the traction rope 41 can maintain the basic structure of the levitation body 3 to prevent it from detaching from the entire product, thus avoiding the situation of falling and damage after power-off; and in cooperation with the traction rope 41, the optional range of the model size of the electromagnet 2 is increased. When the levitation body 3 is heavier, a model with a smaller magnetic force can be selected. On the one hand, since the electromagnet 2 is embedded in the handicraft, choosing a smaller size can reduce its overall heat generation, ensure the service life, and at the same time reduce the material cost; on the other hand, when the size of the entire handicraft is larger, the combined use of the electromagnet 2 and the traction rope 41 can also increase the design diversity of the levitation body 3, including the size, shape of the levitation body 3 and its actions adapted to the traction rope 41, etc.; for example, the levitation body 3 shown in this embodiment is a spherical structure, and it can also be a rotation body structure in other forms with central symmetry, but it is necessary to ensure that the permanent magnet 31 is located at the geometric center of the levitation body 3, so that when the levitation body 3 moves along with the rotating seat 21, it can achieve a stable form of revolving around the central axis of the driven gear ring 52;

[0038] Or as Figure 3 shown, the permanent magnet 31 can also be eccentrically arranged in the levitation body 3; in this form, the levitation body 3 can adopt a flat structure, and the levitation of the levitation body 3 can be in a non-horizontal state, and certain angular changes or other irregular rotations can be achieved during revolution, thereby realizing another manifestation state.

[0039] At the same time, in cooperation with the adjustable magnetic force of the electromagnet 2, it is different from the traditional structure, and the levitation body 3 can be designed to run on the designed track according to the design, realizing preset actions such as floating up and down, and the structure is more novel and diverse.

[0040] The overall size of this magnetic levitation device is small and can be applied to resin handicrafts with different shapes to achieve more manifestation forms. The outer surface of the levitation body 3 can be designed according to requirements, such as a sphere floating in a person's hand, a cloud under the feet, a skateboard in rotation, etc.

[0041] And the above magnetic levitation resin handicraft is produced according to the following process: including the following steps:

[0042] a. Make a silicone mold according to the shape of the resin handicraft, and the obtained silicone mold has an embedding cavity with the same shape as the base 1; the production process of the silicone mold is well-known to those skilled in the art and will not be elaborated here.

[0043] b. Pour unsaturated resin and fillers through the silicone mold, demold after solidification and forming to obtain a blank handicraft of the required shape; the fillers include conventional materials for resin pouring such as curing agents and accelerators;

[0044] c. Place a metal reinforcing bar 6 for reinforcement at the lower end opening corresponding to the embedding cavity on the blank handicraft;

[0045] d. Supplement resin material 61 at the metal reinforcing bar 6 to wrap the metal reinforcing bar 6 to form a clamping end for fixing the base 1; the lower edge of the embedding cavity has a toothed stepped structure, which can place the metal reinforcing bar 6 and is also conducive to the supplement of the resin material 61, and the height dimension of the outer side is larger to wrap the later-supplemented resin material 61 inside to ensure the integrity of the outer surface;

[0046] e. Polish, trim, color, and dry the product obtained in step c;

[0047] f. Install the magnetic levitation device at the corresponding position of the embedding cavity on the product obtained in step d to obtain the magnetic levitation handicraft.

[0048] In this embodiment, in step d, it further includes manually cutting at the wrapping position of the metal reinforcing bar 6 to form an L-shaped installation groove 101 for installing the base 1. Manually use tools such as trimming knives to cut at the port of the embedding cavity to form an installation groove 101 structure with an L-shaped cross-section that meets the installation of the base 1. Because it is too fine and inside, it cannot be directly formed by one-time pouring. Therefore, this form can also improve the yield rate and ensure the stability of the installation structure of the magnetic levitation device.

[0049] The electromagnet 2 shown in this technical solution can be connected to a power source in the form of a corresponding storage battery or an external wire according to different designs. This is not the improvement point of this technical solution and is not limited here. Embodiment 2

[0050] On the basis of Embodiment 1, refer to Figure 4 , a guiding groove 102 is provided at the end of the handicraft main body 100, and a guiding ball 411 adapted to the guiding groove 102 is installed on the towing rope 41. When the driven gear ring 52 rotates, the guiding ball 411 slides in the guiding groove 102. The guiding groove 102 in this embodiment is a wavy groove structure surrounding the inner wall of the end of the handicraft main body 100, and the guiding ball 411 is clamped in the guiding groove 102. In this way, under the action of the guiding ball 411, a certain structural support can be formed for the towing rope 41, and the height of the levitation body 3 can be guided under the condition that the magnetic force of the electromagnet 2 remains unchanged, thereby affecting the running track of the levitation body 3 structurally.

[0051] Similarly, during the production process, in step d, manual cutting is further included at the wrapping position of the metal rib 6 to form a circumferentially distributed guide groove 102 structure. The lower edge of the guide groove 102 has a clamping platform to prevent the guide ball 411 from falling out. This structure is applicable to the application of large-sized handicrafts and is conducive to manual processing operations.

[0052] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all such changes are within the protection scope of the present invention.
