Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Example 1:

as shown in figure 1, the novel ceramic composite plunger comprises a plunger body 1, wherein a rubber layer 2 is wrapped on the plunger body 1. One side of the plug body 1 is provided with a connecting rod 3. One end of the connecting rod 3 is provided with a connecting end 4. The connecting end 4 is used for connecting other power components and providing power for the connecting rod 3, so that the plug body 1 can reciprocate.

Example 2:

as shown in fig. 2 to 5, the difference from embodiment 1 is that two fixed shafts one 5 are provided on the plug body 1. The length of the first fixed shaft 5 is the same as that of the plug body 1. Three sealing grooves 6 are formed in the first fixing shaft 5. A sealing ring 7 is arranged in the sealing groove 6. The fixed shaft is sleeved with a first plunger 8. The first plunger 8 is provided with a fixing hole 9 matched with the fixing shaft. The first plunger 8 moves to the bottom along the fixed shaft, so that one end of the first plunger 8 is flush with the plug body 1.

Above-mentioned setting makes when need be suitable for 1 size of cock body under the different work condition, need not to change new cock body 1, only need establish new plunger 8 at cock body 1 overcoat, carries out whole thickening to cock body 1 for 1 size of cock body that new cock body 1 can the adaptation required under the various different work conditions.

Furthermore, one end of the first fixed shaft 5 is provided with a clamping groove 10. The two sides of the clamping groove 10 are respectively provided with a first circular groove 11 and a second circular groove 12. A spring 13 is arranged in the first circular groove 11, one end of the spring 13 is fixedly connected with a locking rod 14, and the other end of the spring 13 is a free end. When the size of the plug body 1 needs to be further increased, a plurality of plungers 8 with different sizes do not need to be prepared, and the locking rod 14 is pulled to enable the locking rod 14 to be separated from the clamping groove 10. A clamping block 15 is clamped in the clamping groove 10. The latch 15 is provided with a locking hole 16 which is matched with the circular groove. And (3) inserting the clamping block 15 into the clamping groove 10, loosening the locking rod 14, enabling the locking rod 14 to sequentially pass through the first circular groove 11 and the locking hole 16 under the action of the spring 13, and finally entering the second circular groove 12 to complete clamping. The fixture block 15 is fixedly connected with a second fixing shaft 17 which is the same as the first fixing shaft. The structure of the second fixed shaft 17 is the same as that of the first fixed shaft 5, and three sealing grooves 6 are also arranged. Finally, a sealing ring 7 is installed in the sealing groove 6, a new plunger I8 is sleeved on the plug body 1 through a second fixing shaft 17, and the size of the plug body 1 is further improved, so that the plug body 1 can adapt to various working conditions with different requirements.
