DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0018] As Figures 1-3 collectively shown, this embodiment relates to a fitting mechanism for a filter membrane end cap and a sealing ring, including a seat plate 1, on which a first cylinder 2 is installed. The output end of the first cylinder 2 drives a cylinder mounting plate 3 on which a second cylinder 4 is installed. Therefore, it can be understood that the second cylinder 4 moves with the cylinder mounting plate 3. Above the second cylinder 4, there is a middle plate 6. The output end of the second cylinder 4 passes through the middle plate 6 and is linked with a connecting plate 12. The connecting plate 12 is dynamically linked with corresponding expansion blocks 18 through several groups of connecting rod units and slides along a slide rail 16 through a slider 17. Several expansion blocks 18 jointly tension a sealing ring 22. On the middle plate 6, there is a first connecting shaft 10 connected to a top plate 21 at the top. The number of the first connecting shafts 10 is multiple, and the distances from each of the multiple first connecting shafts 10 to the center of the mechanism are the same, so as to ensure the consistency during the operation of this embodiment.

[0019] As Figure 1 shown, this embodiment is designed vertically. The seat plate 1 is connected to the middle plate 6 through a connecting rod 5, which further strengthens the stability of the overall structure. On the basis of the stable structure, the vertical design saves more floor space.

[0020] A plurality of guide shafts 7 are also provided on the cylinder mounting plate 3 and are located outside the second cylinder 4. Each guide shaft 7 passes through the middle plate 6 through a linear bearing 8, and the top end of the guide shaft 7 is connected to the slide rail mounting plate 9. It can be understood that the linear bearing 8 is assembled in the middle plate 6 as Figure 1 shown; the slide rail mounting plate 9 and the connecting plate 12 are at the same horizontal height and are located on the outer side of the connecting plate 12.

[0021] As Figure 2 shown, the slide rail 16 is mounted on the slide rail mounting plate 9. A fixing block 15 is also provided below the slide rail mounting plate 9, and the fixing block 15 is implemented in a manner of connecting one joint of the connecting rod unit. Correspondingly, the connecting rod unit includes a plurality of connecting rods 13, and adjacent two connecting rods 13 are rotatably connected by a rotating shaft 14. The free ends of the connecting rods 13 at both end sides of the connecting rod unit are rotatably connected to the connecting plate 12 and the expansion block 18 respectively through the rotating shaft 14;

[0022] In this embodiment, the number of connecting rods 13 of each group of connecting rod units is set to three. The connecting rod 13 on the inner side of the mechanism is rotatably connected to the connecting plate 12 through the rotating shaft 14. Thus, when the connecting plate 12 is displaced, the connecting rod unit can move accordingly. The connecting rod 13 on the outer side of the mechanism is rotatably connected to the expansion block 18 through the rotating shaft 14. Therefore, when the connecting rod unit moves accordingly, the connecting rod 13 on the outer side drives the expansion block 18 to move, and then the expansion block 18 slides along the slide rail 16 through the slider 17 to achieve the expansion effect. For the smooth movement, the through hole for mounting the rotating shaft 14 on the connecting rod 13 on the outer side is set as a waist-shaped hole to increase the movement range of the connecting rod 13; also as Figure 2 shown, the rotating shaft 14 connecting the middle connecting rod 13 and the connecting rod 13 on the outer side is connected to the fixing block 15, and the fixing block 15 provides a fulcrum for this joint of the connecting rod unit.

[0023] A second connecting shaft 11 with its top end connected to the top block mounting plate 19 is also provided on the middle plate 6. The top edge of the top surface of the top block mounting plate 19 is provided with a top block 20, and the top block 20 is implemented in a manner of supporting the top plate 21. As Figure 3 shown, the top plate 21 is set as a circle, and a plurality of expansion blocks 18 are equally spaced and surrounded in a circle to adapt to the assembly shape of the sealing ring 22.

[0024] As Figure 1 shown, this embodiment further includes an end cover 23 to be assembled with the sealing ring 22.

[0025] The working principle of this embodiment is as follows:

[0026] In the initial state, prepare the sealing ring 22 and the end cap 23 corresponding to the size model. The piston at the output end of the first cylinder 2 is in the extended state, and the piston at the output end of the second cylinder 4 is in the retracted state;

[0027] At the position corresponding to the expansion block 18 of the sealing ring 22, the second cylinder 4 is activated. Its piston extends to drive the connecting plate 12 to move upward, thereby driving the connecting rod unit to move. Then, the expansion block 18 is driven by the connecting rod unit to slide outward along its respective slide rails 16 to expand and deform the sealing ring 22;

[0028] Place the end cap 23 at the corresponding position in the center of the mechanism. The first cylinder 2 is activated. Its piston retracts to drive the cylinder mounting plate 3 to move downward, thereby driving the slide rail mounting plate 9 to move downward, and then driving the expansion block 18 to move downward;

[0029] At this time, the sealing ring 22 is ejected from the expansion block 18 by the top block 20 and the top plate 21 under the reaction force. Then, the sealing ring 22 is sleeved on the end cap 23 under the action of the elastic force, and the working process ends. Just remove the end cap 23 sleeved with the sealing ring 22;

[0030] Finally, the first cylinder 2 and the second cylinder 4 are reset respectively.

[0031] In this way, the filter membrane end cap and sealing ring sleeving mechanism disclosed by the present utility model replaces manual sleeving of the sealing ring, realizes the mechanization and automation of sealing ring sleeving, effectively improves the sleeving efficiency and the qualified product rate, greatly saves manpower and material resources, lays a foundation for subsequent production, and comprehensively improves the production efficiency of the enterprise.

[0032] The above embodiments are not limitations on the present utility model. The present utility model is not limited to the above examples either. Changes, modifications, additions, or substitutions made by those skilled in the art within the technical scope of the present utility model also fall within the protection scope of the present utility model.
