[0005] The advantages of adopting the above technical solution are as follows: in the above technology, the operator first sets the sealing sleeve on the external charging cable, and then sets the fixing sleeve on the sealing sleeve, and then installs the assembly plate on the external charging pile board surface, and the assembly plate and the assembly ring are coaxially provided with through holes at the opening positions on the charging pile board surface corresponding to the charging cable passing through, and the operator moves the fixing sleeve and the sealing sleeve so that the fixing sleeve is fixedly connected to the assembly ring through the connecting piece, and when the fixing sleeve and the assembly ring are gradually fixedly connected, the first step surface and the second step surface gradually abut against each other until the two are tightly fitted, that is, when the fixing sleeve and the assembly ring move relative to each other, the sealing portion is always between the fixing sleeve and the assembly ring, so that the assembly ring gradually squeezes the sealing portion so that the inner side wall of the sealing portion abuts against the rear end face of the fixing sleeve , thereby realizing the sealing of the assembly ring and the fixed sleeve by the sealing part, thereby improving the sealing strength between the assembly ring and the fixed sleeve, thereby improving the sealing between the fixed sleeve and the sealing sleeve. After the assembly ring and the fixed sleeve are fixedly connected, the operator clamps the sealing sleeve through the clamping assembly, thereby further improving the sealing between the sealing sleeve and the fixed sleeve; the waterproof seal between the sealing sleeve and the fixed sleeve and the waterproof seal between the fixed sleeve and the assembly ring are realized through the setting of the above technology, thereby improving the waterproof sealing at the opening of the charging pile board surface, thereby preventing external water or impurities from invading the charging pile and affecting the electronic components, thereby improving the service life of the charging pile. In the above technology, the sealing sleeve is made of a waterproof sealing material, thereby improving the sealing strength of the sealing sleeve.

[0006] The utility model is further configured as follows: a slot for inserting an assembly ring is provided at the rear end of the fixing sleeve, the connecting piece includes a first thread groove provided on the inner peripheral wall of the slot and a second thread groove provided on the outer peripheral wall of the assembly ring, the first thread groove and the second thread groove are threadedly connected, and the inner side wall of the assembly ring is abutted and matched with the bottom wall of the slot.

[0007] The benefits of adopting the above technical solution are: in the above technology, when it is necessary to achieve a fixed connection between the assembly ring and the fixed sleeve, it is only necessary to screw in the fixed sleeve so that the fixed sleeve moves relative to the assembly ring. At this time, the assembly ring is gradually inserted into the slot and the first thread groove and the second thread groove are gradually threadedly matched, so as to achieve a fixed connection between the fixing ring and the assembly ring. At the same time, the sealing between the fixing ring and the assembly ring is improved by the cooperation of the first thread groove and the second thread groove, and the above connection method is adopted to improve the efficiency of disassembly and assembly, reduce cost expenditure, and facilitate the subsequent replacement of parts; at the same time, when the assembly ring is matched with the slot, the inner side wall of the assembly ring will gradually squeeze the sealing part, so that the first step surface and the second step surface gradually abut and match until the two are tight and fit, thereby improving the sealing strength between the assembly ring and the fixed sleeve.

[0008] The utility model is further provided with: an annular groove is opened on the assembly ring, a sealing gasket is arranged in the annular groove, the outer peripheral wall of the sealing gasket is abutted and matched with the inner peripheral wall of the annular groove, the outer side wall of the sealing gasket is abutted and matched with the bottom wall of the annular groove, the inner side wall of the sealing gasket is abutted and matched with the bottom wall of the slot, and the sealing gasket is made of waterproof sealing material.

[0009] The benefit of adopting the above technical solution is that the annular groove and the sealing gasket in the above technology are arranged so that when the assembly ring and the fixed sleeve thread are matched, the assembly ring will drive the sealing gasket to move until the inner wall of the sealing gasket abuts and matches with the bottom wall of the slot, and at the same time, the outer wall of the sealing gasket abuts and matches with the bottom wall of the annular groove, so as to achieve the sealing of the annular groove by the sealing gasket, thereby improving the sealing strength between the slot and the assembly ring. At the same time, the sealing gasket is made of waterproof sealing material, which further improves the sealing strength between the slot and the assembly ring.

[0010] The utility model is further provided with: the clamping assembly includes a clamping ring, the clamping ring is composed of a left clamping plate and a right clamping plate, the left clamping plate and the right clamping plate are arranged opposite to each other and are both arranged in a semi-lunar ring shape, the two ends of the left clamping plate are respectively arranged opposite to the two ends of the right clamping plate, the front end surface of the fixing sleeve is provided with connecting plates at positions corresponding to the two ends of the left clamping plate, the connecting plate is located between the left clamping plate and the right clamping plate, the two ends of the left clamping plate are respectively threadedly connected with adjusting bolts with the corresponding ends of the right clamping plate, and the two adjusting bolts are respectively arranged to cooperate with the threads of the adjacent connecting plates.

[0011] The benefits of adopting the above technical solution are: when the sealing sleeve needs to be clamped and limited, the operator moves the left clamping plate and the right clamping plate so that the left clamping plate and the right clamping plate are relatively close to each other. At this time, the inner circumferential wall of the left clamping plate and the inner circumferential wall of the right clamping plate are partially abutted and matched with the outer circumferential wall of the sealing sleeve, so as to achieve the initial clamping and limiting of the sealing sleeve. After that, the operator screws in the adjusting bolts so that the two adjusting bolts respectively connect the two ends of the left clamping plate with the two ends of the right clamping plate, and the adjusting bolts are threadedly matched with the connecting plate, so as to achieve the abutment and matching of the two ends of the left clamping plate with their respective adjacent connecting plates, and at the same time, the two ends of the right clamping plate are respectively abutted and matched with their respective adjacent connecting plates, so as to achieve the connection and combination of the left clamping plate and the right clamping plate with the fixed sleeve, so as to avoid the displacement of the left clamping plate and the right clamping plate; the clamping and limiting of the sealing sleeve is achieved through the setting of the above technology, and then the clamping and limiting of the charging cable is achieved.
