Description

Technical Field

[0001] This utility model relates to the assembly of internal groove sealing rings, specifically to a mechanism for assembling internal grooves. Background Technology

[0002] In the past, the assembly of internal groove seals involved manually stuffing the seals into the internal grooves, which was inefficient and easily damaged the seals. Utility Model Content

[0003] In view of the above problems, this utility model proposes a mechanism for assembling internal groove sealing rings.

[0004] The technical solution of this utility model: A mechanism for assembling an internal groove sealing ring includes a main body with an annular groove at its lower end and a notch at the lower half of the main body. The mechanism also includes a push rod installed inside the main body, with a protrusion at its lower end located within the notch. As the push rod moves up and down, the protrusion moves upward within the notch to above the annular groove and downward to below the annular groove.

[0005] To further refine the above technical solution, the mechanism also includes a base block with a groove on it. The groove is wider on one side and narrower on the other, with the wider side matching the sealing ring and the narrower side matching the lower end of the main body.

[0006] The advantages of this utility model are that it has a reasonable design, simple structure, efficient assembly of the inner groove sealing ring, and is not easy to damage the sealing ring. Attached Figure Description

[0010] The diagram shows: 1. Main body; 2. Push rod; 3. Base block; 5. Notch; 6. Protrusion; 7. Groove; 8. Sealing ring. Detailed Implementation

[0011] like Figure 1-3As shown, a mechanism for assembling an internal groove sealing ring includes a main body 1, a push rod 2, and a base block 3. The lower end of the main body 1 is provided with an annular groove 4; the lower half of the main body 1 has a notch 5, the push rod 2 is installed inside the main body 1, and the lower end of the push rod 2 is a protrusion 6, which is located inside the notch 5; the base block 3 has a groove 7, one side of which is larger than the other, the larger side of which matches the sealing ring 8, and the smaller side of which matches the lower end of the main body 1.

[0012] Place the sealing ring 8 in the groove 7, at the larger end of the groove 7. Insert the lower end of the main body 1 into the sealing ring 8, so that the sealing ring 8 fits onto the lower end of the main body. Move the lower end of the main body 1 along the groove 7 to the smaller end of the groove 7. The sealing ring 8 moves along with it and is squeezed and deformed, confined within the annular groove 4. The push rod 2 moves upward, and the protrusion 6 moves upward within the notch 5 to above the annular groove 4. During this process, the sealing ring 8 is tightened, causing the sealing ring 8 to change diameter and fall into the annular groove 4. Move the lower end of the main body 1 to the inner groove. The push rod 2 moves downward, and the protrusion 6 moves downward within the notch 5 to below the annular groove 4. During this process, the sealing ring 8 is released and falls into the inner groove, completing the assembly of the inner groove sealing ring.

[0013] The above embodiments are only for illustrating the technical concept and features of the utility model, and are intended to enable those skilled in the art to understand the content of the utility model and implement it accordingly. They should not be construed as limiting the scope of protection of the utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the utility model should be covered within the scope of protection of the utility model.

Claims

1. A mechanism for assembling an internal groove sealing ring, the mechanism comprising a main body, wherein an annular groove is provided at the lower end of the main body; characterized in that, The main body has a notch on the lower half.
