Description

Technical Field

[0001] The utility model relates to the technical field of charging cable accessories for charging piles, in particular to a quick-disassembly waterproof protection sleeve for a charging cable of a charging pile. Background Technique

[0002] An electric vehicle charging pile is a device for supplying power to new energy vehicles. It is fixed in a new energy charging place. At present, the charging pile consists of a charging box, a charging cable and a charging gun. The end of the charging cable is located in the charging box and cooperates with other components in the charging box. The starting end of the charging cable passes through a pre-buried hole opened on the charging pile plate and extends to the outside to cooperate with the charging gun. In the prior art, to ensure that external rainwater does not invade the inside of the charging box through the gap between the charging cable and the pre-buried hole, a protection component is installed between the pre-buried hole and the charging cable. The protection component consists of two oppositely arranged valve flaps, a base sleeve, a matching sleeve and a threaded sleeve. The charging cable is clamped by the two valve flaps, and then the base sleeve is sleeved on the charging cable to realize partial limitation of the charging cable and connection with the valve flaps. Then, the connection with the charging pile plate is realized through the cooperation of the matching sleeve and the base sleeve, and the threaded sleeve is used to connect the base sleeve and the matching sleeve. The whole disassembly and assembly process is cumbersome, resulting in low disassembly and assembly efficiency. At the same time, the charging cable is clamped and sealed through the cooperation of the valve flaps. Since the outer shell of the charging cable is made of rubber material, it has certain elastic properties. Therefore, there will still be gaps when clamping and sealing through the valve flaps, resulting in sealing failure or low sealing strength. At the same time, the overall cost of adopting the above structure is high and the cost performance is low. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a quick-disassembly waterproof protection sleeve for a charging cable of a charging pile, so as to solve the problems of inconvenient disassembly and assembly and low waterproof sealing strength caused by too many parts of the charging cable protection sleeve of the charging pile in the prior art.

[0004] To achieve the above purpose, the utility model provides a quick-disassembly waterproof protection sleeve for a charging cable of a charging pile, including a protection sleeve. The protection sleeve consists of a connecting ring and a plurality of deformation plates for passing through a pre-buried hole of an external charging pile. A connecting hole for passing through an external charging cable is opened on the connecting ring. A connecting piece for detachably connecting with an external charging pile plate is arranged on the connecting ring. The plurality of deformation plates are annularly distributed on the inner wall of the connecting ring, and the plurality of deformation plates are combined to form a deformation hole for passing through an external charging cable. The deformation hole is coaxially communicated with the connecting hole. An extrusion piece for synchronously extruding the plurality of deformation plates to synchronously deform and abut against the outer peripheral wall of the external charging cable is sleeved on the protection sleeve.

[0005] The advantages of adopting the above technical solution are as follows: In the above technology, the operator installs the connecting ring on the charging pile plate through the connecting piece, and coaxially aligns the connecting hole with the embedded hole on the plate. At this time, several deformation plates pass through the embedded hole to the outside of the charging pile. Then, the operator passes the starting end of the charging cable through the connecting hole and the deformation hole to the outside and connects it to the charging gun head. When the charging cable passes through, the inner peripheral walls of several deformation plates are in abutting cooperation with the outer peripheral wall of the charging cable. Then, the operator sleeved the extrusion piece on the protective sleeve so that the extrusion piece synchronously extrudes several deformation plates. The several deformation plates deform synchronously and are in tight cooperation with the outer peripheral wall of the external charging cable, thereby realizing the clamping and limiting of the charging cable by the several deformation plates, making the part where the several deformation plates are in tight cooperation with the charging cable sealed, and thus achieving the sealing function. Adopting the above technical solution is convenient for disassembly and assembly, improves the disassembly and assembly efficiency, and at the same time, the setting of the connecting ring and the deformation plates is convenient for processing and production.

[0006] The present utility model is further provided as follows: The extrusion piece includes a fitting sleeve. The fitting sleeve is annularly arranged and has an opening through which the external charging cable passes. The deformation plate is composed of an abutting end and a connecting end. The connecting ends of several deformation plates are combined to form an annular connecting portion. The outer peripheral wall of the connecting portion is threadedly connected with the inner peripheral wall of the opening. An extrusion ring for synchronously extruding the outer peripheral walls of the abutting ends of several deformation plates is annularly provided on the inner peripheral wall of the opening.

[0007] The advantages of adopting the above technical solution are as follows: In the above technology, after several deformation plates pass through the embedded hole, the operator screws in the fitting sleeve. The fitting sleeve is connected to the connecting portion through the threaded cooperation between the inner peripheral wall of the opening and the outer peripheral wall of the connecting portion, which equivalently realizes the connection between several deformation plates and the fitting sleeve. After the fitting sleeve is screwed in to a certain extent, the extrusion ring synchronously extrudes the abutting ends of several deformation plates, that is, applies a force to the deformation plates, causing the deformation plates to deform and conduct the compressive force to the outer peripheral wall of the charging cable, thereby increasing the contact area and sealing strength between the deformation plates and the charging cable, that is, realizing the tight fit between the abutting ends of the deformation plates and the charging cable. And through the extrusion of the inner peripheral wall of the extrusion ring on the outer peripheral wall of the abutting end, the abutting strength between the inner peripheral wall of the abutting end and the outer peripheral wall of the charging cable is further improved, and then the sealing strength is improved, so as to achieve the waterproof purpose, avoid water seepage between the inner peripheral wall of the deformation hole and the outer peripheral wall of the charging cable, and further avoid water seepage between the inner peripheral wall of the connecting hole and the outer peripheral wall of the charging cable; In the above technology, the waterproof seal between the embedded hole of the charging pile plate and the charging cable is realized through the cooperation of the protective sleeve and the fitting sleeve. Adopting this technical solution improves the disassembly and assembly efficiency and the waterproof seal strength. Compared with the expensive waterproof sleeve in the prior art, the cost of this technology is lower and the cost performance is higher, which is suitable for the production and sale of small and medium-sized enterprises.

[0008] The present utility model is further provided that: between the outer peripheral wall and the end face of the abutting end, a smooth curved surface connection is formed to form an abutting surface, and the abutting surface is inclined relative to the connecting end and the inclination direction of the abutting surface is set towards the axis direction of the deformation hole.

[0009] The advantage of adopting the above technical solution is that: through the arrangement of the abutting surface, it is convenient for the fitting sleeve to be screwed in and for the extrusion ring to perform extrusion, thereby realizing the cooperation between the fitting sleeve and the protective sleeve.

[0010] The present utility model is further provided that: between the inner peripheral wall and the inner side wall of the extrusion ring, a smooth curved surface connection is formed to form an inclined surface for contacting the outer peripheral wall of the abutting end, and the inclination direction of the inclined surface is set in the same direction as the inclination direction of the abutting surface.

[0011] The advantage of adopting the above technical solution is that: in the above technology, between the inner peripheral wall and the inner side wall of the extrusion ring, a smooth curved surface connection is formed to form an inclined surface, and the inclination direction of the inclined surface is set in the same direction as the inclination direction of the abutting end. When the fitting sleeve is screwed in, the inclined surface of the extrusion ring can extrude the abutting surface, so that the extrusion ring synchronously extrudes a plurality of abutting surfaces, causing the abutting ends of a plurality of deformation plates to be deformed and inclined towards the charging cable direction under pressure. And the inner peripheral wall of the abutting end of the deformation plate has been in abutting cooperation with the outer peripheral wall of the charging cable, that is, restricted by the charging cable. When the extrusion ring extrudes, a force will be applied to the abutting end, thereby realizing the expansion and tightening cooperation between the abutting ends of a plurality of deformation plates and the outer peripheral wall of the charging cable, improving the connection strength, and thus realizing the clamping and limiting of the charging cable and the sealing at the clamping position.

[0012] The present utility model is further provided that: on the outer peripheral wall of the connecting ring, a retaining edge for abutting and cooperating with the inner wall of the external charging pile plate member is circumferentially arranged.

[0013] The advantage of adopting the above technical solution is that: in the above technology, the arrangement of the retaining edge is used to abut and cooperate with the inner wall of the plate member, thereby eliminating the gap between the inner wall of the retaining edge and the inner wall of the plate member, and thus improving the sealing performance.

[0014] The present utility model is further provided that: a plurality of connecting bolts for threadedly cooperating with the external charging pile plate member are threadedly connected to the retaining edge, and the plurality of connecting bolts are annularly distributed, and the connecting bolts are the connecting members.

[0015] The advantage of adopting the above technical solution is that: in the above technology, the arrangement of the connecting bolts is used to connect the retaining edge and the plate member, which is convenient for disassembly, improves the disassembly and assembly efficiency, and at the same time reduces the cost expenditure; in the above technology, the number of connecting bolts is not limited and can be installed according to actual installation requirements.

[0016] The present utility model is further provided that: on the inner side wall of the fitting sleeve, a fitting groove for accommodating the bolt ends of a plurality of connecting bolts is provided.

[0017] The advantages of adopting the above technical solution are as follows: In the above technology, the cooperation groove is provided to accommodate the bolt ends of the connecting bolts, that is, the bolt ends of several connecting bolts are all located in the cooperation groove to prevent the connecting bolts from being exposed, improving the aesthetics and avoiding the connection failure between the connecting bolts and the outside plate caused by the rotation of the bolt ends of the connecting bolts. At the same time, the inner side wall of the cooperation sleeve abuts and cooperates with the outer wall of the plate, further reducing the gap between the two, thereby improving the sealing strength.

[0018] The present utility model is further provided that: there is a clearance fit between adjacent deformation plates and a deformation groove is formed.

[0019] The advantages of adopting the above technical solution are as follows: In the above technology, the deformation groove is provided to facilitate a certain amount of movement space when the deformation plate deforms, thereby avoiding the deformation plate from being stuck due to deformation.

[0020] The present utility model is further provided that: the radial cross-sections of several deformation plates are arranged in an arc shape.

[0021] The advantages of adopting the above technical solution are as follows: In the above technology, the radial cross-section of the deformation plate being arranged in an arc shape enables the inner peripheral wall of the deformation plate to better fit the outer peripheral wall of the charging cable, thereby reducing the gap between the deformation plate and the charging cable, and further improving the sealing performance.
