[0029] Furthermore, a rubber ring is provided on one side of the sealing disk 327; the provision of the rubber ring enhances the sealing performance of the sealing disk 327, effectively prevents leakage of the curing agent or sealant in the hydraulic cylinder 321, improves the sealing and stability of the entire sealing structure, and ensures the smooth progress of the sealing operation and the durability of the sealing effect.

[0030] Working principle: Step 1: During installation, multiple core columns 2 are passed through the bottom of the housing 1. When passing through the housing 1, the trigger block 342 is pushed by the fixed disk 21 provided on the core column 2, so that the trigger block 342 contracts the extrusion spring, and pushes the second rack rod 341 to move in the same direction. The second rack rod 341 is meshed with the gear, and the first rack rod 323 is driven to move in the opposite direction of the second rack rod 341. The movement of the first rack rod 323 drives the push rod 322 and the connecting disk 324 to move synchronously. The connecting disk 324 drives the movable plug 326 to move in the hydraulic cylinder 321, so that the curing agent in the hydraulic cylinder 321 is squeezed and discharged to the output end. The curing agent enters the rubber bag 33 and mixes with the sealing colloid. At this time, the volume of the rubber bag 33 expands; At the same time, when the fixed disk 21 moves to the bottom of the housing 1, the fixed rod 223 simultaneously penetrates the through groove provided on the fixed disk 21 and the plug-in groove provided on the sliding block 221. The bottom of the fixed rod 223 is inclined to move toward the bottom to push the sliding block 221 and the needle 222 to move toward one end of the rubber bag 33. The tip of the needle 222 is set to pierce the rubber bag 33, so that the mixed sealant in the rubber bag 33 overflows and fills the inside of the sealing frame 11, thereby filling the inside of the sealing frame 11, and then filling the connection seam between the bottom of the housing 1 and the stem 2. When the fixed disk 21 moves to a horizontal position with the sealing frame 11, the clamping block is pushed by the elastic force of the spring to engage with the clamping groove on the fixed disk 21 to achieve positioning of the fixed disk 21; The advantages of this filling method are: 1. During the installation process, the curing agent and sealant are mixed and filled simultaneously, with high filling efficiency and fast speed, avoiding the low efficiency of manual filling and curing in sequence; The sealing frame 11 is arranged in an L-shape, and the sealant is squeezed and filled directly into the interior by the extrusion force, so that the gap can be filled more fully and uneven filling can be avoided. Compared with the traditional outer edge filling sealant, the sealing effect is better. The sealant is filled in this linkage mode, which reduces the labor of manual filling and sealing, making the installation more efficient. Step 2: After completion, the resin 4 and the cover shell 6 are sleeved from one end of the core column 2, and the cover shell 6 is threadedly connected to the bottom of the shell 1 by manual rotation; Step 3: inject the heated and melted sealant through the injection port at the top of the main block 71, and the sealant flows into the auxiliary block 73 through the connecting bridge 72 to fill the outer wall of the stem 2. After solidification, the connection end between the top of the shell 1 and the stem 2 is sealed; It should be noted that: when the fixed disk 21 moves toward the top to the top of the trigger block 342, the elastic force of the spring will push the trigger block 342 to reset. The reset trigger block 342 can support the bottom of the fixed disk 21 and play a positioning role. At the same time, when the second rack rod 341 is reset, it will drive the gear and the push rod 322 to reset and move. When the push rod 322 pushes the support rod 325 to move toward the output end of the hydraulic cylinder 321, it can extrude the curing agent. In order to avoid the sealing disk 327 moving and extracting the sealant in the rubber bag 33 during resetting, the sealing disk 327 opens when the push rod 322 pulls the movable plug 326 to reset, and the airflow will enter the hydraulic cylinder 321 through the movable plug 326, thereby avoiding the above-mentioned problem and improving the stability of the sealing construction.

[0031] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
