[0034] Example 1, reference Figure 1~Figure 2 , which is the first embodiment of the utility model, proposes a water seal pressing tool for pressing the fixed end of the sealing ring into the leather cup, one end of the sealing ring has a positioning convex ring, including a positioning seat 1, a linear drive mechanism 2, a positioning plate 3, and a leather cup outer support plate 4, and an operating hole 5 is opened on the positioning seat 1; the linear drive mechanism 2 is arranged on the positioning seat 1, and the linear drive mechanism 2 has at least two, and all the linear drive mechanisms 2 are arranged around the operating hole 5; the positioning plate 3 is arranged on the linear drive mechanism 2, and all the positioning plates 3 are moved closer to or away from each other by means of the telescopic movement of the linear drive mechanism 2; the leather cup outer support plate 4 is arranged on one side of the positioning plate 3, and the leather cup outer support plate 4 is contracted by means of the linear drive mechanism 2, so that the opening of the leather cup mounted on the periphery of all the leather cup outer support plates 4 is larger than the outer diameter of the positioning convex ring.

[0035] Furthermore, if Figure 1 and Figure 2As shown, all the linear drive mechanisms 2, positioning plates 3 and outer support plates 4 of the leather cups are located on the same side of the operating hole 5, and the positioning plate 3 is located between the outer support plates 4 of the leather cups and the operating hole 5. When in use, the linear drive mechanism 2, positioning plate 3 and outer support plates 4 of the leather cups are located on the left side of the operating hole 5, that is, on the left side of the positioning seat 1, and the outer support plates 4 of the leather cups are located on the left side of the positioning plate 3. When in use, the operator sets the leather cups to the periphery of all the outer support plates 4 of the leather cups with his left hand, and inserts the sealing ring into the outer support plates 4 of the leather cups at the operating hole 5 with his right hand. Compared with setting the outer support plates 4 of the leather cups in the operating hole 5, the requirements for the size of the operating hole 5 can be reduced.

[0036] Furthermore, if Figure 1 and Figure 2 As shown, there are three linear drive mechanisms 2, all of which are evenly arranged in the circumferential direction around the operating hole 5, and the linear drive mechanisms 2, the positioning plates 3 and the leather cup outer support plates 4 are arranged one by one. The three linear drive mechanisms 2 are all provided with positioning plates 3, and the three positioning plates 3 are all provided with leather cup outer support plates 4. The three leather cup outer support plates 4 work together to make the force on the open end of the leather cup more uniform when it is expanded, and it is more convenient to insert the sealing ring.

[0037] Furthermore, if Figure 2 As shown, all the leather cup outer support plates 4 are spliced ​​together to form a circular ring structure, and the outer diameter of the circular ring structure is less than or equal to the opening diameter of the leather cup. When the linear drive mechanism 2 is extended, the outer diameter of all the leather cup outer support plates 4 after splicing together is less than or equal to the opening diameter of the leather cup, so at this time, the leather cup is put on the outer periphery of all the leather cup outer support plates 4, which is more convenient, faster, and saves time and effort.

[0038] Furthermore, the positioning plate 3 and the leather cup outer support plate 4 are an integrally formed structure, and the connection is more firm and reliable.

When the leather cup is put on the outer support plate 4 of the leather cup, the end surface of the open end of the outer support plate 4 of the leather cup contacts the positioning plate 3, and the positioning plate 3 can effectively play a limiting role, which can remind the operator that the leather cup has been installed in place.

[0040] Furthermore, if Figure 1 As shown, the distance d between the outer wall of the positioning plate 3 and the outer wall of the leather cup outer support plate 4 is greater than the wall thickness of the leather cup opening. When the leather cup is mounted on the leather cup outer support plate 4, the end surface of the entire leather cup outer support plate 4 at the opening is in contact with the positioning plate 3, and the limiting effect is better.

[0041] Furthermore, if Figure 1 and Figure 2 As shown, it also includes a mounting plate 6 and a locking bolt 7. The mounting plate 6 is arranged at the bottom of the positioning seat 1, and a mounting hole is opened on the mounting plate 6; the locking bolt 7 is arranged at the mounting hole.

The structure is simple, the connection is firm and reliable, and the disassembly and assembly are convenient and fast, saving time and effort.

[0042] Furthermore, the linear drive mechanism 2 and the positioning plate 3 are detachably connected, so that the positioning plate 3 can be easily disassembled and replaced.

[0043] In this embodiment, an operation hole 5 is provided on the positioning seat 1, three linear drive mechanisms 2 are evenly arranged around the circumferential direction of the operation hole 5 on the positioning seat 1, the positioning plate 3 is arranged on the linear drive mechanism 2, and the cup outer support plate 4 is arranged on one side of the positioning plate 3.

First, the linear drive mechanism 2 is extended to push all the positioning plates 3 toward the center of the operating hole 5. The positioning plates 3 drive the leather cup outer support plates 4 toward the center of the operating hole 5. Then, the operator uses his left hand to put the opening end of the leather cup on the periphery of all the leather cup outer support plates 4. Then, the linear drive mechanism 2 is retracted back to the initial position to expand the opening end of the leather cup. The operator holds the sealing ring in his right hand and inserts the sealing ring into the leather cup at the operating hole 5. Finally, the leather cup is removed from the leather cup outer support plate 4. When the opening end of the leather cup returns to its initial size, the sealing ring can be clamped, and the positioning convex ring of the sealing ring can be clamped into the positioning groove on the inner wall of the leather cup, which saves time and effort and can improve production efficiency.
