[0021] Please refer to Figures 1 to 3 As shown, this utility model embodiment provides a plug for sealing the outlet of a water channel cavity. The plug includes a plug body 100, a sealing ring 200, and a handle 300; the plug body 100 is provided with an annular groove 110; the sealing ring 200 is installed in the annular groove 110 and is adapted to make sealing contact with the inner wall of the water channel cavity; the handle 300 is detachably connected to the plug body 100, and when the handle 300 is connected to the plug body 100 and the plug body 100 is placed in the water channel cavity, the handle 300 at least partially protrudes from the outlet of the water channel cavity.

[0022] According to the plug of this utility model embodiment, the worker takes the handle 300 of the plug and inserts the plug body 100 into the water channel cavity of the product to be processed. The sealing ring 200 on the plug body 100 makes a sealing contact with the water channel cavity to isolate the water channel cavity from the external environment. After the plug body 100 is fixed, the worker removes the handle 300. At this time, the plug body 100 is completely located in the water channel cavity and does not affect the external processing of the product to be processed. After processing is completed, the handle 300 is reassembled to the plug body 100 to remove the plug body 100 and the sealing ring 200 from the water channel cavity.

[0023] According to the embodiment of this utility model, the plug body 100 is easily disassembled and assembled from the water channel cavity by the provision of a handle 300. After sealing the water channel cavity, the handle 300 is removed so that the plug body 100 and the sealing ring 200 remain in the water channel cavity. While sealing the water channel cavity, there is no protruding part on the surface of the product to be processed that interferes with the tool path during processing. This reduces the difficulty of programming the tool path for the operator and improves the processing efficiency of the product to be processed. In addition, the sealing ring 200 effectively prevents the chips and waste generated during processing from falling into the water channel cavity, ensuring the surface quality of the water channel cavity and reducing the difficulty of cleaning the product to be processed.

[0024] In this embodiment, the sealing ring 200 is circular. Of course, the shape of the sealing ring 200 and the plug body 100 can be adapted to the outlet of the water channel cavity with different shapes, such as using a rectangular sealing ring 200 and a plug body 100.

[0025] In some embodiments, combined with Figures 1 to 3 As shown, the handle 300 includes a handle portion 310 and a connecting portion 320, with the connecting portion 320 located at one end of the handle portion 310. The plug body 100 is provided with a connecting groove 131 and a clearance hole 121. The connecting groove 131 communicates with the outside through the clearance hole 121. The connecting portion 320 is adapted to pass through the clearance hole 121 and connect with the connecting groove 131. Along the insertion direction of the handle 300, the cross-sectional area of ​​the clearance hole 121 is smaller than the cross-sectional area of ​​the connecting groove 131. The connecting portion 320 can rotate in the connecting groove 131 so that the upper surface of the connecting portion 320 is limited and abuts against the inner wall of the connecting groove 131.

[0026] In this embodiment, the operator takes the handle 310 of the handle 300 to move the connecting part 320, passes through the clearance hole 121 along the connecting part 320 and enters the connecting groove 131. The connecting part 320 rotates a certain angle around the axis of the handle 300. At this time, when the connecting part 320 retracts in the opposite direction of the insertion direction, the upper surface of the connecting part 320 abuts against the inner wall of the connecting groove 131 and cannot leave the connecting groove 131, thereby realizing that the handle 300 drives the plug body 100 to move.

[0027] In this embodiment, the handle 300 and the plug body 100 can be disassembled and assembled by simply rotating the connecting part 320, which is more efficient than traditional detachable connection methods (such as threaded connection, bolt connection, etc.).

[0028] In other embodiments, the detachable connection between the handle 300 and the plug body 100 can also be a threaded connection, a bolted connection, a snap-fit ​​connection, etc.

[0029] In some embodiments, combined with Figures 1 to 3 As shown, the connecting part 320 is strip-shaped and symmetrical about the rotation axis of the handle 300; the clearance hole 121 is strip-shaped and has a clearance fit with the connecting part 320; the connecting groove 131 is a cylindrical groove, and the axis of the cylindrical groove is parallel to the insertion direction of the handle 300. Thanks to the cylindrical groove 131, the connecting part 320 of the handle 300 can rotate 360 ​​degrees freely in the cylindrical groove, which is convenient to adapt to the operating habits of different operators.

[0030] In other embodiments, the connecting part 320 may be fan-shaped or a long strip extending from one side of the rotation axis of the handle 300. The clearance hole 121 is adapted to the shape of the connecting part 320 so that the connecting part 320 can pass through. The connecting groove 131 may also be fan-shaped to ensure that after the connecting part 320 is rotated, it at least partially abuts against the inner wall of the connecting groove 131 in the opposite direction of the insertion direction of the handle 300.

[0031] In some embodiments, combined with Figures 1 to 3 As shown, the plug body 100 includes a plug connecting block 120 and a plug guide block 130. The plug connecting block 120 and the plug guide block 130 are detachably connected. The plug connecting block 120 is provided with a clearance hole 121, and the plug guide block 130 is provided with a connecting groove 131. Separating the plug body 100 facilitates the independent machining of the clearance hole 121 and the connecting groove 131, reducing manufacturing difficulty.

[0032] In some embodiments, combined with Figures 1 to 3 As shown, the plug connecting block 120 and the plug guide block 130 are connected by a threaded portion. By rotating the mating distance of the threaded portion, the distance between the plug connecting block 120 and the plug guide block 130 can be adjusted to adjust the length of the plug body 100 to meet the usage requirements of different products to be processed.

[0033] In other embodiments, the plug connecting block 120 and the plug guide block 130 can also be connected by means of adhesive, snap-fit, bolt connection, etc.

[0034] In some embodiments, combined with Figures 1 to 3As shown, an annular groove 110 is formed between the plug connecting block 120 and the plug guide block 130. When installing the sealing ring 200, it can first be fitted onto one end of the threaded portion. As the plug connecting block 120 and the plug guide block 130 rotate and engage, the annular groove 110 gradually shrinks and compresses the sealing ring 200, ensuring a seal between the sealing ring 200 and the annular groove 110, thus improving the sealing effect of the sealing ring 200 on the water channel cavity. Furthermore, the gradually shrinking groove spacing of the annular groove 110 allows it to accommodate sealing rings 200 with different cross-sectional thicknesses, improving the plug's adaptability. Moreover, compared to directly fitting the sealing ring into the annular groove 110, the clamped annular groove 110 eliminates the need to expand the sealing ring 200 during installation, effectively extending the service life of the sealing ring 200.

[0035] In some embodiments, combined with Figures 1 to 3 As shown, the plug guide block 130 is provided with a guide cone surface 132. Along the direction from the plug guide block 130 to the plug connecting block 120, the guide cone surface 132 gradually extends away from the axis of the plug guide block 130. The guide cone surface 132 facilitates the insertion process of the plug body 100, improving the sealing efficiency.

[0036] In some embodiments, the surface of the handle 310 is provided with an anti-slip portion (not shown in the figure) to improve the stability of the operator rotating and moving the handle 300. The anti-slip portion may be silicone, a towel, or an anti-slip texture etched on the surface of the handle 310, which may be provided at least partially on the surface of the handle 310.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
