DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Mechanical seal is a shaft sealing device used in rotating fluid machinery. It is a device that prevents fluid leakage by keeping at least one pair of end faces perpendicular to the rotating axis in contact and sliding relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism. As an important industrial component, the design and application of mechanical seals cover a wide range of needs in rotating equipment.

[0022] See also Figure 1-Figure 5 As shown, the present embodiment provides a mechanical connection sealing device, including a mechanical connection device base 1 and a connecting plate 11. The outer wall of the mechanical connection device base 1 and the outer wall of the connecting plate 11 are jointly provided with an insertion component 2, and the insertion component 2 is used for quickly sealing and connecting the mechanical connection device base 1 and the connecting plate 11. The insertion component 2 includes a plug-in plate 21 and an insertion plate 22. When the mechanical connection sealing device is urgently needed, it is not convenient to quickly perform a sealing connection, and when the machine fails, it takes a lot of time to disassemble the mechanical connection sealing device, which is not convenient for immediate maintenance of the machine, delaying the working time and having low practicality. Therefore, the specific steps are as follows: inserting the insertion plate 22 into the plug-in plate 21 facilitates the quick connection of the mechanical connection device base 1 and the connecting plate 11, so that they are in a sealed connection state.

[0023] The improvement of this embodiment is that:

[0024] Insert the insertion plate 22 into the inner wall of the slot 211, and the sealing gasket of the insertion plate 22 and the inner wall of the plug-in plate 21 fits tightly to achieve a sealed connection effect. At the same time, the rotating threaded shaft 28 drives the circular shaft 26 to move, and the circular shaft 26 drives the rotating blocks 25 on both sides to rotate, and the clamping block 27 is clamped inside the two rotating blocks 25, thereby increasing the connection stability between the mechanical connection device base 1 and the connecting plate 11, facilitating and quickly installing or disassembling the connection between the mechanical connection device base 1 and the connecting plate 11, and improving practicality.

[0025] In order to enable the mechanical connecting device base 1 and the connecting plate 11 to be quickly connected, two plug-in boards 21 are symmetrically fixedly connected to the outer wall of the mechanical connecting device base 1, and slots 21 are provided on the inner walls of the two plug-in boards 21. A circle of sealing gaskets are provided on the inner wall of the slots 211, and two insertion boards 22 are symmetrically fixedly connected to the outer wall of the connecting plate 11. The outer walls of the two insertion boards 22 are plugged and adapted with the sealing gaskets on the inner walls of the slots 211. The two insertion boards 22 are aligned with the slots 211 on the inner walls of the plug-in boards 21 and slowly inserted. The insertion boards 22 are inserted into the plug-in boards 21, and the sealing gaskets around the inner wall of the slots 211 tightly wrap the outer walls of the insertion boards 22 to make them in a sealed state, so as to facilitate the quick installation of the mechanical connecting device base 1 and the connecting plate 11.

[0026] Considering that the above-mentioned method of connecting the mechanical connecting device base 1 and the connecting plate 11 is not stable enough, a fixed plate 23 is fixedly connected to the outer wall of the mechanical connecting device base 1, and a fixed block 24 is fixedly connected to the outer wall of the fixed plate 23. The inner wall of the fixed block 24 is symmetrically rotatably connected to two rotating blocks 25. The rotating blocks 25 are in a "U" shape, and a circular shaft 26 is rotatably connected between the two rotating blocks 25. A clamping block 27 is fixedly connected to the outer side of the connecting plate 11. The outer wall of the clamping block 27 is clamped and adapted with the inner walls of the two rotating blocks 25. The circular shaft 26 drives the rotating blocks 25 on both sides to rotate on the inner wall of the fixed block 24. The two rotating blocks 25 clamp the clamping block 27 on the inner walls of the two rotating blocks 25, thereby further strengthening the connection between the mechanical connecting device base 1 and the connecting plate 11 and improving stability.

[0027] Considering that the circular shaft 26 needs to be displaced to drive the rotating block 25 to rotate, the inner wall of the circular shaft 26 is threadedly connected with a threaded shaft 28, and the end of the threaded shaft 28 extending into the inner wall of the fixed plate 23 is fixedly connected with a first bevel gear 281, and the outer wall of the first bevel gear 281 is meshed with a second bevel gear 29, and the lower end of the second bevel gear 29 rotates on the inner wall of the fixed plate 23, and the upper end of the second bevel gear 29 is fixedly connected with a rotating rod 291, and the second bevel gear 29 drives the first bevel gear 281 of the outer wall to mesh and rotate, and the end of the first bevel gear 281 rotates on the inner wall of the fixed plate 23, and the first bevel gear 281 drives the threaded shaft 28 at the end to rotate, and the threaded shaft 28 rotates on the inner wall of the circular shaft 26, driving the circular shaft 26 to move.

[0028] Taking into account that it is inconvenient for users to rotate the second bevel gear 29, the end of the rotating rod 291 extending out of the upper surface of the fixed plate 23 is fixedly connected to a rotating cap 292, and a plurality of protrusions are evenly arranged around the outer wall of the rotating cap 292. The rotating cap 292 drives the rotating rod 291 to rotate inside the fixed plate 23, and the rotating rod 291 drives the end of the second bevel gear 29 at the lower end to rotate on the inner wall of the fixed plate 23, so that users can rotate the second bevel gear 29 conveniently.

[0029] In summary, the working principle of this scheme is as follows:

[0030] When the mechanical connection sealing device of the utility model is used, the mechanical connection device base 1 and the connecting plate 11 are fixed on the machine to be connected, and the two insertion plates 22 are aligned with the slots 211 on the inner wall of the plug-in plate 21 and slowly inserted, and the insertion plate 22 is inserted into the plug-in plate 21, and the sealing gasket around the inner wall of the slot 211 tightly wraps the outer wall of the insertion plate 22 to make it in a sealed state, and the rotating cap 292 is rotated, and the rotating cap 292 drives the rotating rod 291 to rotate inside the fixed plate 23, and the rotating rod 291 drives the end of the second bevel gear 29 at the lower end to rotate on the inner wall of the fixed plate 23, and the second bevel gear 29 drives the first bevel gear 281 on the outer wall to mesh and rotate, and the end of the first bevel gear 281 rotates on the inner wall of the fixed plate 23, and the first bevel gear 281 rotates on the inner wall of the fixed plate 23. 1 drives the threaded shaft 28 at the end to rotate, and the threaded shaft 28 rotates on the inner wall of the round shaft 26, driving the round shaft 26 to move, and the round shaft 26 drives the rotating blocks 25 on both sides to rotate on the inner wall of the fixed block 24, and the two rotating blocks 25 clamp the clamping blocks 27 on the inner walls of the two rotating blocks 25, further strengthening the connection between the mechanical connecting device base 1 and the connecting plate 11. When it is necessary to disassemble the connection between the mechanical connecting device base 1 and the connecting plate 11, the rotating cap 292 is rotated in the opposite direction to loosen the fixation of the clamping blocks 27 by the two rotating blocks 25, and the connecting plate 11 is slid horizontally to pull the insert plate 22 out of the inner wall of the plug-in plate 21 until the plug-in plate 21 is completely separated from the insert plate 22, so that the user can quickly install and disassemble the connection between the mechanical connecting device base 1 and the connecting plate 11.
