Example 1

Referring to fig. 1, an embodiment of the present application provides a carrier structure 010. Such a load bearing structure 010 includes a frame 100 and a platform assembly 200. The frame 100 includes a base plate 170 and four posts 190. Four posts 190 are spaced apart from the mounting surface of base plate 170. The post 190 extends in an adjustment direction X that is generally perpendicular to the mounting surface of the base plate 170. Four struts 190 are located approximately at the four corners of a rectangle. Within each strut 190 is provided a float channel 101, the float channel 101 extending in the adjustment direction X. A main channel is provided in the bottom plate 170, and four floating channels 101 communicate through the main channel. The floating channels 101 are filled with filling liquid 110, the filling liquid 110 flows through the four floating channels 101 through the main channel, and when the frame body 100 is inclined, the filling liquid 110 in the four floating channels 101 flows, so that the liquid surfaces in the four floating channels 101 are at the same level 010a.

The platform assembly 200 includes a carrier 230 and four floats 210. Each float 210 is fixedly connected to the carrier 230. The float member 210 extends into the float channel 101, the float member 210 floats on the level of the fill fluid 110, and the float member 210 also follows the level of the fill fluid 110 as the level of the fill fluid 110 changes. The center of gravity of the carrier 230 is located approximately at the center of the four floats 210 such that the weight transferred by the carrier 230 to the four floats 210 is approximately equal. As the frame body 100 tilts, the filling liquid 110 flows through the four floating channels 101, and the liquid level of the filling liquid 110 in the four floating channels 101 is kept at the same horizontal plane 010a, so that the four floating pieces 210 in the four floating channels 101 are located at the same horizontal plane 010a, and the bearing platform 230 is kept horizontal, and then the material 030 borne on the bearing platform 230 is kept horizontal.

It will be appreciated that the number of floating channels 101 may be other than four, and may be three, five, six, or other numbers. The number of the floating pieces 210 corresponds to the number of the floating channels 101, each floating piece 210 is arranged in one floating channel 101, and the bearing platform 230 is supported by a plurality of floating pieces 210, so that the bearing platform 230 can stably bear the material 030.

Fig. 2 shows a transparent view of a form of the frame 100 to show the primary channel 103 and the floating channel 101. As shown in fig. 2, the main flow channel 103 in such a frame 100 includes a first flow dividing channel 1031 and a second flow dividing channel 1033, the first flow dividing channel 1031 connects two floating channels 101 diagonally, and the second flow dividing channel 1033 connects the other two floating channels 101. The first and

second flow dividers

1031 and 1033 are crossed such that the first and

second flow dividers

1031 and 1033 communicate, and the four floating channels 101 communicate through the first and

second flow dividers

1031 and 1033.

Fig. 3 shows a transparent view of another form of the frame body 100 to show the primary channels 103 and the floating channels 101. As shown in fig. 3, the main flow channel 103 in such a housing 100 includes an annular flow channel. The annular flow passage flows through the four floating passages 101 so that the four floating passages 101 communicate.

It will be appreciated that the main flow channel 103 may take other forms as long as the main flow channel 103 enables the filling liquid 110 to flow between the floating channels 101.

The float member 210 may be a solid structure having a density less than the fill fluid 110 such that the float member 210 floats on the surface of the fill fluid 110 and supports the carrier member. The float 210 may also be a hollow structure, with the hollow structure of the float 210 having a smaller weight but still having a larger drain volume, thereby creating a greater buoyancy to hold the carrier. Alternatively, the floating member 210 may be a porous structure to reduce the weight, and the pores of the porous structure may also allow the floating member 210 to have a larger liquid discharge volume when the pores cannot be completely filled with the filling liquid 110. The drain volume refers to the volume of the fill fluid 110 displaced by the portion of the float member 210 immersed into the fill fluid 110.

The inner wall of the floating channel 101 is provided with an anti-wetting layer 150. The anti-wetting layer 150 is used to place the filling liquid 110 wetting the inner wall of the floating channel 101. The material of the anti-wetting layer 150 may be selected according to the filling liquid 110 that is required to fill the floating channel 101. It is understood that when the filler liquid 110 is gallium indium tin alloy, the anti-wetting layer 150 may be a gallium oxide layer. The four pillars 190 of the frame 100 may be made of glass material, and a gallium oxide layer is formed on the inner wall of the floating channel 101, so as to prevent the gallium indium tin alloy from infiltrating into the glass pillars 190. So that the gallium indium tin alloy can smoothly flow in the floating channel 101. When the frame 100 is tilted, the gallium indium tin alloy flows instantly to respond to the tilting of the frame 100, and the liquid surfaces of the gallium indium tin alloy in the four floating channels 101 are kept at the same horizontal plane 010a.

As shown in fig. 1, in this bearing structure 010, a first communication hole 1011 extending in the adjustment direction X is provided at a side surface of the floating passage 101. The platform assembly 200 further includes a first connecting rod 251, one end of the first connecting rod 251 is connected to the carrier 230, and the other end passes through the first connecting hole 1011 and is connected to the floating member 210. The first connecting rod 251 extends substantially perpendicular to the adjustment direction X. The size of the first communication hole 1011 is larger than the size of the first connection rod 251 in the adjustment direction X. The first connecting rod 251 can move along the adjusting direction X relative to the frame 100, so that the entire platform assembly 200 can move along the adjusting direction X relative to the frame 100. It will be appreciated that the first connecting member may be connected to the upper half of the floating member 210, so that the first through hole 1011 is also located as above the floating member 210 as possible, so as to reduce the leakage rate of the filling liquid 110 from the first through hole 1011. On a projection plane perpendicular to the adjustment direction X, the projections of the carrier 230 are located between the projections of the four floats 210. In this carrying structure 010, the center of gravity of the carrying platform 230 is more easily located near the center of the four floating members 210, so that the carrying platform 230 can be stably supported by the four floating members 210. Optionally, the first connecting rod 251 is detachably connected to the carrying platform 230, so that the floating member 210 is located in the floating channel 101, and after the first connecting rod 251 extends out of the floating channel 101, the first connecting rod 251 is connected to the carrying platform 230. The connection between the first connecting rod 251 and the carrying platform 230 may be a threaded connection. For example, a screw thread is provided at the outer circumference of the first connecting rod 251, and a screw hole is provided at the sidewall of the loading stage 230 such that the first connecting rod 251 can be screw-fitted with the screw hole.

Fig. 4 shows a cross-sectional view of one form of load bearing structure 010 to illustrate the form of connection of the load bearing platform 230 and the float 210. As shown in fig. 4, in this bearing structure 010, a second communicating hole 1013 is provided at one end of the floating channel 101 in the adjustment direction X. The platform assembly 200 further includes a second connection rod 253, one end of the second connection rod 253 is connected to the bearing stage 230, and the other end passes through the second communication hole 1013 and is connected to the floating member 210. The second connection rod 253 may extend parallel to the adjustment direction X. The second connection rod 253 passes through the second communication hole 1013 in the adjustment direction X such that the second connection rod 253 can move in the adjustment direction X with respect to the frame body 100. When the float 210 moves in the adjustment direction X within the float channel 101, the second connecting rod 253 passing through the second communicating hole 1013 can also move in the adjustment direction X. On a projection plane perpendicular to the adjustment direction X, the projection of the partial position of the carrying table 230 coincides with the projection of the four floats 210.

It is understood that the second connecting rod 253 may not be a straight rod, and the second connecting rod 253 may include a first portion extending parallel to the adjustment direction X to pass through the second communicating hole 1013 and a second portion extending perpendicular to the adjustment direction X to connect the carrying stage 230. On a projection plane perpendicular to the adjustment direction X, the projections of the carrier 230 are located between the projections of the four floats 210.

The platform assembly 200 also includes a securing portion (not shown). The fixed portion is connected to the platform assembly 200. The fixing portion is detachably connected to the frame body 100. When the fixing portion is connected to the frame body 100, the relative position of the floating member 210 and the frame body 100 in the adjustment direction X is restricted. Alternatively, the fixing portion may include a bolt screwed to the float member 210, and the length of the bolt inserted into the float member 210 may be controlled by rotating the bolt. The bolt includes a head portion that extends out of the housing 100. When the control head does not contact the frame 100, the float 210 can move freely with respect to the frame 100 in the adjustment direction X. When the length of the control bolt inserted into the floating member 210 is increased such that the head of the bolt and the floating member 210 clamp together the side wall forming the floating passage 101, the floating member 210 is relatively fixed to the frame body 100 in the adjustment direction X.

It will be appreciated that the fixing portion may be connected to the frame 100. The fixing portion can move on the frame 100 along the adjustment direction X, and is connected to the platform assembly 200 after aligning to the platform assembly 200, so that the platform assembly 200 and the frame 100 are relatively fixed along the adjustment direction X.

The carrying platform 230 further has a carrying groove 231, and the carrying groove 231 is used for containing the material 030, especially the liquid material 030 can be stably contained in the carrying groove 231. The carrying tank 231 is disposed in the middle area of the carrying platform 230, and when the liquid material 030 is contained in the carrying tank 231, the center of gravity of the material 030 can be coincident with the center of gravity of the carrying platform 230, so that the whole center of gravity of the carrying platform 230 and the material 030 is located approximately in the middle position of the four floating members 210.

Such a carrying structure 010 may not be used to adjust the level of the frame 100 when in use. Even if the frame body 100 is inclined to some extent, the filling liquid 110 can flow through the four floating channels 101, so that the four floating members 210 are kept at the same level 010a. So that the carrier 230 remains horizontal. When the carrier 230 is held horizontally, the material 030 on the carrier 230 may be held horizontally. The level is automatically adjusted by the four float members 210 to maintain the material 030 on the level 010a.

Example two

Referring to fig. 5, an embodiment of the present application provides an oven 001. Such an oven 001 comprises a housing 050 and a carrying structure 010 provided in embodiment one.

The case 050 has a drying chamber 050a. The oven 001 may further include a heater provided in the drying chamber 050a. When the heater heats, the air temperature in the drying cavity 050a is raised, so that the water of the material 030 placed in the drying cavity 050a is evaporated rapidly. It can be appreciated that the drying chamber 050a may also be provided with a communication port, where the communication port is connected to an air flow conveyor, and the air flow conveyor conveys heated air into the drying chamber 050a, so that the air temperature in the drying chamber 050a is raised.

The bearing structure 010 is arranged in the drying chamber 050a. The frame 100 is connected to the box 050, and the carrier 230 carries the material 030 thereon. The material 030 is dried in a drying chamber 050a.

The filler liquid 110 filled in the floating channel 101 is gallium indium tin alloy. The gallium indium tin alloy is in a liquid state at the normal temperature of 20 ℃, and the gallium indium tin alloy is kept in the liquid state after the temperature in the drying cavity 050a is increased. The gallium indium tin alloy can circulate in the four floating channels 101, so that the liquid levels in the four floating channels 101 are at the same level 010a.

The boiling point of the gallium indium tin alloy is higher than 1300 ℃, and the temperature in the drying cavity 050a can not reach such high temperature, so that the gallium indium tin alloy is not easy to evaporate in the drying cavity 050a.

The density of the gallium indium tin alloy reaches 6.44g/cm ³ The buoyancy generated by the same float member 210 immersed in the gallium indium tin alloy is 6.44 times that generated by immersing in water. The gallium indium tin alloy may create a greater buoyancy force on the platform assembly 200 to support the platform assembly 200.

The oven 001 shown in fig. 5 includes two load bearing structures 010. The two carrying structures 010 are arranged at intervals along the adjustment direction X. The carrying structure 010 is mounted in the drying chamber 050a by a support table 090. As shown in fig. 5, due to the dislocation of the support table 090, the frame bodies 100 in both the bearing structures 010 are inclined with respect to the horizontal plane 010a. But by keeping the filling liquid 110 in the four floating channels 101 in the same carrier structure 010 at the same level 010a, the carrier 230 of each carrier structure 010 can be kept horizontal.

Fig. 6 shows a cross-sectional view of a carrier 230 containing a liquid material 030, wherein the carrier 230 is not held horizontally. Fig. 7 shows a cross-sectional view of a carrier 230 containing a liquid material 030, wherein the carrier 230 is kept horizontal. As shown in fig. 6 and 7, if the stage 230 is kept horizontal, the thickness of the liquid material 030 can be kept uniform. If the stage 230 is tilted, the liquid material 030 will have a shape with a large thickness on one side and a small thickness on the other side. The liquid material 030 is dried in the drying chamber 050a to form a solid state. If the loading stand 230 is kept horizontal during the drying process, the dried material 030 can be kept to have a uniform thickness. If the carrying platform 230 is not kept horizontal during the drying process, the dried material 030 will have a shape with a large thickness on one side and a small thickness on the other side. The thickness refers to the dimension of the material 030 in the adjustment direction X.

The application provides a using method of the oven 001, which comprises the following steps:

s101, a carrying structure 010 is placed in the drying chamber 050a.

S102, the bearing structure 010 is kept stationary, so that the filling liquid 110 flows through each floating channel 101, and finally the liquid surfaces of the filling liquid 110 in all the floating channels 101 are kept at the same level 010a. If the bearing structure 010 further includes a fixing portion, after the bearing structure 010 is placed still, the fixing portion is controlled to connect the frame body 100 and the platform assembly 200, so as to fix the frame body 100 and the platform assembly 200.

S103, carrying the material 030 on the carrying platform 230.

And S104, closing a door 070 of the oven 001, and lifting the temperature in the drying cavity 050a to dry the material 030.

Such an oven 001 may be used without adjusting the level of the frame 100 in the load-bearing structure 010. Even if the frame body 100 is inclined to some extent, the filling liquid 110 can flow through the four floating channels 101, so that the four floating members 210 are kept at the same level 010a. Which in turn keeps the carrier 230 horizontal. When the carrier 230 is held horizontally, the material 030 on the carrier 230 may be held horizontally. The level is automatically adjusted by the four float members 210 to maintain the material 030 on the level 010a.

In addition, other variations within the spirit of the present application will occur to those skilled in the art, and of course, such variations as may be made in light of the spirit of the present application are intended to be included within the scope of the present disclosure.
