[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: A waterproof mechanism for a cable, such as Figures 1-4 As shown, it includes a connecting cable 1 and a thickened arc 101 installed on the outside of the connecting cable 1. The outside of the thickened arc 101 is screwed with a fastening cylinder 104, and a sealing ring 103 is installed inside the fastening cylinder 104. The sealing ring 103 is sleeved on the outside of the connecting cable 1. A sealing connection ring 108 is provided on one side of the fastening cylinder 104. A connecting cylinder 105 is installed between the sealing connection ring 108 and the fastening cylinder 104. The connecting cylinder 105 is plugged into the fastening cylinder 104 through a connecting ring 106. The connecting cylinder 105 is plugged into the sealing connection ring 108 through an auxiliary ring 107, and a guide block 2 is installed inside the connecting cylinder 105. A snap-on ring groove 202 is provided on the outside of the guide block 2.

[0026] When the device is in use, first put the thickened arc 101 on the outside of the connecting cable 1, and then rotate the fastening cylinder 104. Under the extrusion limit of the thickened arc 101, the sealing ring 103 is limited inside the fastening cylinder 104, so that the connection between the fastening cylinder 104 and the connecting cable 1 is sealed. Then, the connecting ring 106 and the fastening cylinder 104 are rotated and sealed, and the position of the clamping ring groove 202 is limited. The connecting cylinder 105 and the guide block 2 are tightly connected and placed. Before the connecting cable 1 is connected to the device on one side, it is sealed. Then, under the rotation seal of the sealing connecting ring 108 and the auxiliary ring 107, the effect of simultaneously sealing both sides of the connecting cylinder 105 is achieved, thereby ensuring the stable sealing of the connection of the connecting cable 1 when it is connected and used, and improving its sealing performance during connection.

[0027] like Figures 1-4 As shown, the connecting ring 106 and the auxiliary ring 107 are respectively installed at both ends of the connecting tube 105, and the connecting ring 106 is screwed together with the inner wall of the fastening tube 104, and the auxiliary ring 107 is screwed together with the inner wall of the sealing connecting ring 108.

[0028] By setting the connecting ring 106, the auxiliary ring 107 and the two side components to be threaded connections, and then adding existing sealing gaskets between the two side surfaces of the connecting tube 105 and the two side components, the accuracy of the position during connection and the stability of the sealing effect are ensured, thereby improving the waterproof performance of the internal guide block 2 when supported.

[0029] like Figures 1-4 As shown, a connector 203 is installed on one end of the inner wall of the sealing connection ring 108 away from the auxiliary ring 107 , and the connector 203 is threadedly connected to the inner wall of the auxiliary ring 107 .

[0030] A connection auxiliary ring 204 is installed on the outer side of the connector 203 , and the connection auxiliary ring 204 is screwed together with the inner wall of the sealing connection ring 108 by means of a thread.

[0031] While the connector 203 is rotated and tightened inside the auxiliary ring 107, the connection auxiliary ring 204 is rotated and tightened inside the sealing connection ring 108, thereby doubly limiting the position of the connector 203, and forming a two-layer sealing protection effect under the separate rotation of the connector 203 and the connection auxiliary ring 204, thereby improving the waterproof performance of the connector 203 when connected to the connection cable 1.

[0032] Example 2: A waterproof mechanism for a cable, such as Figures 1-4 As shown, the guide block 2 is connected to the outer sealing ring through the clamping ring groove 202, and the outer surface of the guide block 2 is tightly connected to the side of the inner wall of the connecting tube 105.

[0033] By adding a sealing ring inside the clamping ring groove 202 and then tightly squeezing the guide block 2 against the inner wall of the connecting tube 105, the sealing ring is under pressurized state to improve the sealing effect, and, under the tight connection between the guide block 2 and the connecting tube 105, the sealing performance of the guide block 2 during use is further improved.

[0034] like Figures 1-4 As shown, guide holes 201 are provided at both ends of the guide block 2, and the guide holes 201 are used for guiding the inside of the cable.

[0035] The interior of the connector 203 is communicated with the guide hole 201 , and the interior of the guide hole 201 and the interior of the connector 203 are simultaneously used for limiting the interior of the cable.

[0036] By moving the internal harness of the cable under the guidance of the guide hole 201 and the connector 203, the accuracy of the installation angle is improved under the simultaneous limiting guidance of the connector 203, thereby improving the sealing stability during connection and use.

[0037] Working principle: First, the thickening arc 101 is placed on the outside of the connecting cable 1, and then the fastening cylinder 104 is rotated. Under the extrusion limit of the thickening arc 101, the sealing ring 103 is limited inside the fastening cylinder 104, so that the connection between the fastening cylinder 104 and the connecting cable 1 is sealed. Then the connecting ring 106 is rotated and sealed with the fastening cylinder 104, and the position of the clamping ring groove 202 is limited. The connecting cylinder 105 is tightly connected and placed with the guide block 2. Before the connecting cable 1 is connected to the device on one side, it is sealed, and then the connecting ring 1 is sealed. 08 and the auxiliary ring 107 rotate and seal, so as to achieve the effect of simultaneously sealing both sides of the connecting tube 105. While the connector 203 is rotated and tightened inside the auxiliary ring 107, the connecting auxiliary ring 204 is rotated and tightened inside the sealing connecting ring 108, thereby doubly limiting the position of the connector 203, and forming a two-layer sealing protection effect under the separate rotation of the connector 203 and the connecting auxiliary ring 204, thereby ensuring the stable sealing of the connection of the connecting cable 1 when it is connected and used, and improving its sealing performance during connection.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
