DETAILED DESCRIPTION OF THE INVENTION

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Referring to Figures 1-7 , a preparation device for high-purity MLCC dielectric materials based on a hydrothermal synthesis and cold sintering collaborative process, including a low-temperature high-pressure sintering press body 1. A control seat 11 is fixedly arranged on the low-temperature high-pressure sintering press body 1. A control panel 13 is fixedly arranged on the control seat 11, and a protective plate 2 is rotatably installed on the control seat 11 through a rotating hinge 12. A movable plate 3 is movably arranged on the protective plate 2. A slot 111 is adaptively opened on the control seat 11 corresponding to the movable plate 3. Limiting members 5 are movably arranged on both sides of the slot 111, and limiting grooves 33 are adaptively opened on both sides of the movable plate 3 corresponding to the limiting members 5.

[0019] Among them, rotating hinges 12 are installed on both sides above the control seat 11, and the protective cover 2 is rotatably opened and closed through the rotating hinges 12. Through the setting of the rotating hinges 12, the opening and closing of the protective cover 2 can be realized.

[0020] Among them, guiding members 21 are fixedly installed on both sides of the top of the protective cover 2, and guiding grooves 32 are adaptively opened on the movable plate 3 corresponding to the guiding members 21. Through the adaptive setting between the guiding members 21 and the guiding grooves 32, the stability of the protective cover 2 during movement can be improved.

[0021] Among them, a handle 31 is fixedly installed on the movable plate 3, and an anti-slip pad is arranged on the handle 31. Through the setting of the handle 31, it is convenient for users to move the movable plate 3. Through the setting of the anti-slip pad, it is convenient for users to grasp the handle 31.

[0022] Among them, side grooves 112 are opened on both sides of the control 11 where the slot 111 is located, and the limiting members 5 are adaptively located and movable in the side grooves 112.

[0023] Among them, sliding blocks 52 are fixedly arranged on both sides of the limiting member 5, and sliding grooves 113 are adaptively opened on the inner wall of the side groove 112 corresponding to the sliding blocks 52. Through the adaptive setting between the sliding blocks 52 and the sliding grooves 113, the stability of the limiting member 5 during movement can be improved.

[0024] Among them, springs 4 are installed outward on the inner walls of the side grooves 112, and the other ends of the springs 4 are connected to the limiting members 5. Through the setting of the springs 4, the limiting members 5 can be pushed outward so that the limiting members 5 can be stably clamped in the limiting grooves 33.

[0025] Wherein, one side of the limiting member 5 facing the slot 111 is provided with an inclined surface 51, and the inclined surfaces 51 are all adapted to the movable plate 3. Through the arrangement of the inclined surface 51, when the user pushes the movable plate 3 inwards, the clamping between the limiting member 5 and the limiting groove 33 can be automatically realized.

[0026] Wherein, the protective covers 2 are all made of transparent materials, and seals are provided at the openings of the protective covers 2. Through the arrangement of the seals, the sealing performance of the protective covers 2 can be improved, so as to improve the protection effect of the protective covers 2 on the control panel 13.

[0027] In this embodiment, the low-temperature and high-pressure sintering press body 1 drives the rearrangement and plastic deformation of powder particles through ultra-high pressure (200–800 MPa), and combines the interfacial dissolution-precipitation effect of the transient liquid-phase solvent (such as Bi-Li-B eutectic) to achieve ceramic densification at low temperature (<400°C). Its core principle is that high pressure forces the particles to be in close contact, and the solvent reduces the diffusion activation energy, enabling atoms to migrate efficiently at low temperature to fill the pores, achieving a theoretical density of >95%, while inhibiting grain growth, avoiding component volatilization and grain coarsening caused by traditional high-temperature sintering, significantly reducing energy consumption and being compatible with base metal electrodes. It should be noted that the specific structure and working mode of the low-temperature and high-pressure sintering press body 1 are prior arts and do not belong to the technical problems of protecting the control panel 13 required in this technical solution, so they will not be elaborated in this invention.

[0028] Furthermore, when the user needs to operate the control panel 13, only need to pull the limiting members 5 on both sides outwards, thereby releasing the mutual clamping between the limiting member 5 and the limiting groove 33. Subsequently, the user only needs to pull the movable plate 3 outwards through the handle 31, and then turn the protective cover 2 upwards to lift it.

[0029] When the user lifts the protective cover 2 upwards by ninety degrees, the protective cover 2 is completely lifted. Subsequently, the user only needs to release the handle 31, and the movable plate 3 can automatically move downwards by gravity. At this time, the movable plate 3 can move to the gap between the control seat 11 and the protective cover 2 by gravity, so as to prevent the opened protective cover 2 from automatically closing. At this time, the user can operate the control panel 13.

[0030] Furthermore, when the user needs to close the protective cover 2, only need to drive the protective plate 3 upwards through the handle 31 to move the movable plate 3 out of the gap between the control seat 11 and the protective cover 2.

[0031] Subsequently, the user can rotate the protective cover 2 downward to close it. At this time, the movable plate 3 is adapted and aligned with the slot 111. Then, the user only needs to push the movable plate 3 towards the slot 111. When the movable plate 3 completely moves into the slot 111, the limiting member 5 can be engaged into the limiting groove 33, thereby fixing the movable plate 3. In this way, the movable plate 3 can be fixedly assembled above the control seat 11, and then the fixing of the protective cover 2 can be achieved. This fixing method of the protective cover 2 is simple and convenient, facilitating the operation of the user.

[0032] In the present invention, the preparation of materials can be realized through the low-temperature and high-pressure sintering press body 1. Through the adapted engagement between the limiting member 5 and the limiting groove 33, the movable plate 3 can be fixed in the slot 111, thereby realizing the fixing of the protective cover 2. Thus, the protection of the control panel 13 can be achieved through the protective cover 2. This protection method of the control panel 13 is simple and convenient, facilitating the operation of the user.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes, should be covered within the protection scope of the present invention.
