Detailed implementation manners

[0021] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the specific implementation manners of this application will be clearly and completely described below in conjunction with the accompanying drawings in the implementation manners of this application.

[0022] As Figure 1 shown, a crucible fixing device 100 is shown. This crucible fixing device 100 is used to fix a graphite crucible. Specifically, the graphite crucible is basically cylindrical. The graphite crucible is placed on the crucible fixing device 100, and the crucible fixing device 100 at least partially surrounds the circumference of the graphite crucible and fixes the graphite crucible to improve the connection stability between the crucible fixing device 100 and the graphite crucible, and can be applicable to graphite crucibles of different sizes, thereby improving the versatility of the crucible fixing device 100. The crucible fixing device 100 provided in this application can protect the graphite crucible to prevent the graphite crucible from being damaged by bumping during the fixing process, and thus is beneficial to improving the safety performance of the graphite crucible. To clearly illustrate the technical solution of the application, the front, rear, left, right, up, and down as Figure 1 shown are also defined. In this application, the length direction of the crucible fixing device 100 refers to the above-mentioned front-rear direction, the width direction of the crucible fixing device 100 refers to the above-mentioned left-right direction, and the vertical direction refers to the above-mentioned up-down direction.

[0023] As Figures 1 to 3As shown, as an implementation manner, the crucible fixing device 100 includes a support base 11 and an adjustment assembly 12. The support base 11 is the main structure of the crucible fixing device 100. A support area 101 for carrying a graphite crucible is formed on the support base 11. The graphite crucible is arranged within the support area 101. The adjustment assembly 12 is used to fix the graphite crucible. The adjustment assembly 12 is fixed on the support base 11. There are multiple adjustment assemblies 12, and the multiple adjustment assemblies 12 are all arranged around the support area 101. Thus, when the graphite crucible is arranged within the support area 101, the adjustment assembly 12 can be in contact with the graphite crucible to form a limit for the graphite crucible, avoiding relative movement between the graphite crucible and the support base 11, and further realizing the fixation of the graphite crucible. Specifically, the adjustment assembly 12 includes an adjustment plate 121, an adjustment rod 122, and an adjustment block 123. The adjustment plate 121 is fixedly connected to the support base 11. The adjustment block 123 is connected to the adjustment rod 122. The adjustment rod 122 has a degree of freedom of movement relative to the adjustment plate 121. The adjustment block 123 is located within the support area 101, and the adjustment rod 122 can drive the adjustment block 123 to move within the support area 101. In the above setting, the adjustment rod 122 is mainly used to control the movement of the adjustment block 123. Thus, when the graphite crucible is arranged within the support area 101, the adjustment block 123 moves to be in contact with the graphite crucible. After the adjustment blocks 123 of the multiple adjustment assemblies 12 are in contact with the graphite crucible, the multiple adjustment blocks 123 can apply pressure to the graphite crucible from different angles, thereby restricting the change in the relative position between the graphite crucible and the support base 11, and further being able to fix the graphite crucible on the support base 11 through the adjustment block 123, thereby being able to improve the connection stability between the graphite crucible and the crucible fixing device 100.

[0024] Furthermore, the adjustment rod 122 is threadedly connected to the adjustment plate 121, and the adjustment block 123 is rotatably connected to the adjustment rod 122. The adjustment rod 122 also has a degree of freedom of rotation relative to the adjustment block 123. In this application, the adjustment plate 121 has internal threads, and the adjustment rod 122 has external threads. When the adjustment rod 122 is threadedly connected to the adjustment plate 121, the adjustment rod 122 and the adjustment plate 121 can form a structure of a lead screw and nut, thereby being able to convert the rotary motion of the adjustment rod 122 into the linear motion of the adjustment block 123. And because there is a degree of freedom of rotation between the adjustment rod 122 and the adjustment block 123, the movement of the adjustment block 123 will not be affected by the rotation of the adjustment rod 122. Thus, it can not only reduce the frictional resistance between the adjustment rod 122 and the adjustment plate 121, but also realize the refined control of the movement of the adjustment block 123, be able to adjust the distance of the adjustment block 123 from the center of the support area 101, thereby being able to improve the movement precision of the adjustment block 123 and avoid damaging the graphite crucible due to the adjustment block 123 applying too much pressure on the graphite crucible.

[0025] In this embodiment, the adjusting assembly 12 further includes a limiting collar 124. The limiting collar 124 is rotatably connected to the adjusting rod 122. The adjusting rod 122 can pass through the limiting collar 124 and the adjusting plate 121, and the limiting collar 124 is threadedly connected to the adjusting rod 122. Specifically, the limiting collar 124 is located on the side of the adjusting plate 121 away from the adjusting block 123. During the rotation of the adjusting rod 122, the adjusting block 123 and the limiting collar 124 move along the axis of the adjusting rod 122. When the limiting collar 124 moves to abut against the adjusting plate 121, the limiting collar 124 can cooperate with the adjusting plate 121 to limit the continuous rotation of the adjusting rod 122, thereby restricting the movement of the adjusting block 123. This can not only prevent the pressure exerted by the adjusting block 123 on the graphite crucible from being too large, but also avoid the loosening of the adjusting block 123 resulting in relative displacement between the graphite crucible and the support seat 11. It can be understood that by changing the position of the limiting collar 124 on the adjusting rod 122, the maximum moving distance of the adjusting block 123 can be changed, so as to be applicable to graphite crucibles of different sizes and improve the versatility of the crucible fixing device 100.

[0026] In this embodiment, the adjusting assembly 12 further includes an adjusting handwheel 125. The adjusting handwheel 125 is connected to the end of the adjusting rod 122 away from the adjusting block 123. The adjusting handwheel 125 can drive the adjusting rod 122 to rotate so that the adjusting hole can move within the support area 101 along the axis direction of the adjusting rod 122. The adjusting handwheel 125 includes a wheel disc 1251 and a hand rod 1252. The wheel disc 1251 is fixedly connected to the end of the adjusting rod 122 away from the adjusting block 123; the hand rod 1252 is fixedly connected to the side of the wheel disc 1251 away from the adjusting rod 122. The hand rod 1252 is in a cylindrical shape, and the axis of the hand rod 1252 is parallel to the axis of the adjusting rod 122, and the axis of the hand rod 1252 does not coincide with the axis of the adjusting rod 122. Through the above settings, the adjusting handwheel 125 can facilitate the operator to control the rotation of the adjusting rod 122 and improve the convenience of adjusting the adjusting assembly 12.

[0027] As an embodiment, the adjusting assembly 12 further includes a connecting member 126. The adjusting block 123 is made of rubber material. The connecting member 126 is fixedly connected to the adjusting block 123. One end of the adjusting rod 122 close to the adjusting block 123 is fixedly connected to the connecting member 126. An abutting arc surface 1231 is formed at the end of the adjusting block 123 away from the connecting member 126, and the abutting arc surface 1231 is used to abut against the graphite crucible. Through the above settings, the abutting arc surface 1231 can increase the contact area between the adjusting block 123 and the graphite crucible, improve the stability of fixing the graphite crucible, and the rubber material of the adjusting block 123 has a certain elasticity, so that while the adjusting block 123 exerts pressure on the graphite crucible, it can also avoid damaging the outer wall of the graphite crucible.

[0028] As an implementation manner, the support base 11 includes a support body 111 and a support plate 112. The adjustment plate 121 is connected to the support body 111. The support plate 112 is located above the support body 111 and is fixedly connected to the support body 111. A clamping groove 1121 is formed on the support plate 112, and the adjustment plate 121 is clamped in the clamping groove 1121.

[0029] Specifically, along the vertical direction, at least part of the support plate 112 is recessed downward to form a sliding groove 1122, and at least part of the adjustment block 123 extends downward to form a sliding portion 1232. The sliding portion 1232 is clamped in the sliding groove 1122. The adjustment rod 122 can drive the sliding portion 1232 to move in the sliding groove 1122. Thus, the sliding groove 1122 can limit the moving direction of the adjustment block 123, so that the adjustment block 123 can only move along the sliding groove 1122, and further facilitate the abutment of the adjustment block 123 against the graphite crucible. Further, a reinforcing groove 1123 is also formed on the support plate 112. The clamping groove 1121 and the sliding groove 1122 communicate through the reinforcing groove 1123. The adjustment assembly 12 further includes a reinforcing plate 127. The reinforcing plate 127 is fixedly connected to the support body 111 and the adjustment plate 121, and the reinforcing plate 127 is also clamped in the reinforcing groove 1123. Through the above settings, the reinforcing plate 127 can improve the connection stability between the adjustment plate 121 and the support plate 112, avoid the deformation and damage of the adjustment plate 121 due to the pressure of the limiting collar 124, and further improve the structural stability of the crucible fixing device 100.

[0030] As an implementation manner, the crucible fixing device 100 further includes a traveling wheel 13. The traveling wheel 13 is located below the support body 111 and is fixedly connected to the support body 111. The traveling wheel 13 can drive the support body 111 to move. Through the above settings, it is convenient for the operator to move the crucible fixing device 100, thereby improving the convenience of the operator to operate the crucible fixing device 100.

[0031] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of this application.
