AI Technical Summary
The existing nested installation method of metal sealing rings cannot effectively connect and fix them, resulting in gaps in the nested installation and affecting the sealing performance.
The nested sealing ring design includes sealing ring one, sealing ring two, sealing ring three, and sealing ring four. The precise positioning and firm connection of multiple sealing rings are achieved through structures such as conical groove, convex ring, L-shaped groove, inverted T-shaped insert, and inclined limiting protrusion.
It enables convenient connection and fixation of multiple sealing rings, avoids nested installation gaps, and improves the stability and reliability of sealing performance.

Abstract
Claims
1. A pump body seal ring nest positioning device comprising a nested seal ring (1) characterised in that: The nested sealing ring (1) is composed of sealing ring one (2), sealing ring two (3), sealing ring three (4) and sealing ring four (5). Sealing ring one (2), sealing ring two (3), sealing ring three (4) and sealing ring four (5) are arranged sequentially from bottom to top. The top of the interior of sealing ring one (2), sealing ring two (3) and sealing ring three (4) is provided with a conical groove (6). The bottom of sealing ring two (3), sealing ring three (4) and sealing ring four (5) is fixedly installed with a convex ring (7). The outer ring surface of the convex ring (7) is provided with a conical structure that matches the conical groove (6).
2. A pump body seal ring nest positioning device as defined in claim 1, wherein: The top of each of the sealing rings 1 (2), 2 (3) and 3 (4) is provided with L-shaped grooves (8) at equal intervals. The L-shaped grooves (8) are all connected to the outer ring surfaces of the sealing rings 1 (2), 2 (3) and 3 (4). The top of each of the sealing rings 1 (2), 2 (3) and 3 (4) is provided with a vertical groove that extends through to the bottom of the L-shaped groove (8).
3. The pump body sealing ring nesting positioning device according to claim 2, characterized in that: The top of the lower part of the L-shaped groove (8) is an extrusion slope (10), and an inclined limiting protrusion (11) is provided at equal intervals on the extrusion slope (10).
4. A pump body seal ring nest positioning device as defined in claim 3 wherein: The bottom of the sealing ring 2 (3), sealing ring 3 (4) and sealing ring 4 (5) are all fixedly installed with inverted T-shaped inserts (9) at equal intervals. The inverted T-shaped inserts (9) are inserted between the L-shaped groove (8) and the vertical groove. A pressure-bearing slope (12) matching the extrusion slope (10) is provided on one side of the top of the lower end of the inverted T-shaped inserts (9). An inclination-limiting protrusion 2 (13) matching the inclination-limiting protrusion 1 (11) is provided at equal intervals on the pressure-bearing slope (12).
