[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Example 1

[0025] Reference Figure 1-6 , an aluminum alloy flange with convenient connection, comprises a main plate 1 and a sub-plate 2, the middle parts of the main plate 1 and the sub-plate 2 away from each other are connected with pipes, the main plate 1 is symmetrically fixed with positioning protrusions 3 on the side facing the sub-plate 2, and the sub-plate 2 is provided with matching positioning grooves 4 corresponding to the positioning protrusions 3, and the edges of the main plate 1 and the sub-plate 2 away from each other are installed with mounting frames 5, and a linkage plate 7 is slidably inserted on the frame body of the mounting frame 5 through an adjusting screw 6, and a top spring 8 is jointly provided between the end of the adjusting screw 6 and the linkage plate 7, and the lower end of the linkage plate 7 extends to the side of the other plate body and is installed with a storage box 9, and the storage box 9 is filled with a color-carrying coating liquid, and the storage box 9 can be made of glass, which is a round or rectangular cylinder, and the coating liquid is filled inside it, and then it is sealed at the opening, which can be easily purchased on the market and will not be described in detail in this scheme.

[0026] Example 2

[0027] Reference Figure 1-6 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0028] The end of the upper end of the linkage plate 7 is rectangular and is slidably mounted on the upper end of the mounting frame 5. A screw 10 is installed on the side of the upper end of the linkage plate 7 through a thread. The end of the screw 10 abuts against the outer wall of the upper end of the mounting frame 5. The upper end of the linkage plate 7 is rectangular, thereby providing a certain degree of guiding effect for the linkage plate 7. Under the action of the screw 10, the linkage plate 7 can be fixed after the position is determined, that is, the linkage plate 7 is prevented from moving by itself during subsequent use, thereby causing the storage box 9 and the disk body to loosen contact; a penetration opening is provided in the middle of the linkage plate 7, and a guide rod 11 is inserted into the penetration opening. The guide rod 11 One end of the guide rod 5 is fixed to the frame of the mounting frame 5, and one side of the guide rod 5 is provided with scale patterns. The setting of the guide rod 11 further improves the stability of the linkage plate 7 when it moves, and under the action of the scale patterns, personnel can easily judge the contact pressure between the storage box 9 and the disk body at this time, so that when the disk body is loose, the storage box 9 can be quickly and sensitively squeezed and finally broken; the storage box 9 is connected to the linkage plate 7 by bonding, and the side of the storage box 9 away from the lower end of the linkage plate 7 is attached to the outer wall of the adjacent disk body. The bonding installation method is convenient for the storage box 9 to be installed between the linkage plate 7.

[0029] A contact ring 12 is rotatably installed at the end of the adjusting screw 6 away from the linkage plate 7. A contact groove is provided on the side of the contact ring 12 facing the top spring 8. The contact ring 12 is connected to the end of the top spring 8 through the contact groove. The setting of the contact ring 12 is convenient for avoiding interference with the top spring 8 when the adjusting screw 6 rotates; a locking bolt 13 is provided at the lower end of the mounting frame 5, and the mounting frame 5 is connected to the main disk 1 and the auxiliary disk 2 through the locking bolt 13. The setting of the locking bolt 13 facilitates the installation and disassembly of the mounting frame 5, and a positioning column is provided at the lower end of the mounting frame 5. Two card grooves are provided on the side where the main disk 1 and the auxiliary disk 2 are in contact with each other, and a sealing ring 14 is commonly clamped in the card groove. The setting of the sealing ring 14 is convenient for sealing between the flanges after installation.

[0030] When the flange connection is needed, the personnel directly moves the sub-disk 2 closer to the main disk 1, and finally the two disk bodies fit together and then are fixed by bolts or other fasteners. At this time, the flange connection effect is achieved. In this process, since there are two connecting protrusions 3, and the end of the connecting protrusion 3 facing the sub-disk 2 is the small end, and the end of the positioning groove 4 on the sub-disk 2 facing the main disk 1 is the large end, when the two are close to each other, the personnel can pre-position them very conveniently, and then as the two disk bodies approach each other, they are gradually rotated under the action of the connecting protrusion 3, and finally complete positioning is achieved, that is, under the joint action of the connecting protrusion 3 and the positioning groove 4, the flange proposed in this scheme is more convenient to connect, that is, it solves the defect that the traditional scheme has a large number of positioning pins and a small diameter, which makes it inconvenient for personnel to position, that is, it improves the convenience of flange connection.

[0031] At the same time, in the above process, the personnel can control the storage box 9 to fit tightly against the surface of another disk body by rotating the adjusting bolt 6, and through the cooperation of the guide rod 11 and the scale pattern, the personnel can accurately judge the pressure between the storage box 9 and the disk body at this time, that is, the personnel can control the pressure to be slightly smaller than the deformation resistance of the storage box 9 itself, that is, when the disk bodies are gradually loosened due to vibration, the disk bodies are separated from each other by a slight distance. At this time, the disk body pushes the storage box 9 to move outward, but the storage box 9 drives the linkage plate 7 to move when it is blocked by the top spring 8, so that the storage box 9 is subjected to a force greater than its own strength at this time, that is, the storage box 9 is squeezed and broken, and then the colored liquid inside the storage box 9 flows out, thereby reminding the personnel.

[0032] It should be further explained that the upper end of the linkage plate 7 is rectangular, which provides a certain degree of guiding effect for the linkage plate 7, and under the action of the screw 10, the linkage plate 7 can be fixed after the position is determined, that is, the linkage plate 7 is prevented from moving on its own during subsequent use, thereby causing the contact between the storage box 9 and the disk body to loosen; the setting of the guide rod 11 further improves the stability of the linkage plate 7 during movement, and under the action of the scale pattern, personnel can easily judge the contact pressure between the storage box 9 and the disk body at this time, so that when the disk body is loose, the storage box 9 can be quickly and sensitively squeezed and finally broken; the contact ring 12 is connected to the end of the top spring 8 through the contact groove, and the setting of the contact ring 12 is convenient for avoiding interference with the top spring 8 when the adjusting screw 6 is rotated; the setting of the sealing ring 14 is convenient for sealing between the installed flanges.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
