Description

Technical Field

[0001] This utility model relates to the field of cable fixing technology, and in particular to a concealed cable fixing structure. Background Technology

[0002] To ensure a secure connection between the cable and the charging gun, a fixing component for securing the cable is usually installed at the tail of the charging gun. Traditional fixing components are installed on the outside of the tail of the charging gun, making the charging gun look bulky and affecting its appearance. Furthermore, the exposed connectors increase the possibility of damage to the connectors. Therefore, an internal cable fixing structure is used.

[0003] Traditional cable fixing structures are not secure enough and are inconvenient to hide inside the device, resulting in a bulky charging gun that affects its appearance. They also make it difficult to avoid the possibility of damage, thus limiting their applicability in use. Utility Model Content

[0004] The purpose of this invention is to provide a concealed cable fixing structure to solve the problem that existing concealed cable fixing structures are not secure enough.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a built-in cable fixing structure, including a housing and a head;

[0006] One end of the housing is fixed with a head, and the other end of the housing has a cable body passing through it. A connection structure is provided on the outside of the cable body at one end of the housing.

[0007] The connecting structure has a fixing mechanism inside the housing at one end, and a limit structure is provided on one side of the fixing mechanism.

[0008] The outer side of the machine head is equipped with a protective structure.

[0009] When using this device, the inclusion of a fixing mechanism facilitates its secure mounting, thereby improving its applicability; the inclusion of a connecting structure facilitates its assembly and disassembly, enhancing its ease of use; the inclusion of a limiting structure facilitates its positioning, improving its stability; and the inclusion of a protective structure provides protection, enhancing its safety.

[0010] Preferably, the connection structure includes a plug, an inlet, a connecting bolt, and a mating platform. The plug is fitted onto the outside of the cable body at one end of the housing. An inlet is evenly distributed along one side of the inside of the plug, and a connecting bolt passes through the interior of each inlet. The mating platform is threaded onto the outside of one end of each connecting bolt. By fitting the plug onto the outside of the cable body and moving it to a suitable position, when the plug is inserted into the housing, it moves the connecting bolt into the mating platform.

[0011] Preferably, the plug and the cable body form a sliding structure, and one side of the mating platform is fixedly connected to the inner wall of the housing. With the cooperation of the connecting bolts and the mating platform, the plug and the housing are fixed together, and the risk of damage to the connecting bolts is reduced under the influence of the burial inlet.

[0012] Preferably, the fixing mechanism includes a first arc-shaped piece, a fixing bolt, and a second arc-shaped piece. The first arc-shaped piece is disposed at one end of the plug, and the second arc-shaped piece is hinged to one end of the first arc-shaped piece. A fixing bolt passes through the interior of both the first and second arc-shaped pieces at one end. The interiors of the first and second arc-shaped pieces are semi-circular, and protrusions are evenly distributed on their inner walls. When the first and second arc-shaped pieces rotate to align, the protrusions sink into the outer sheath of the cable body, allowing the first and second arc-shaped pieces to be firmly clamped to the outside of the cable body.

[0013] Preferably, the inner walls of the first and second arc-shaped pieces abut against the outer wall of the cable body. The first and second arc-shaped pieces are fixedly connected by fixing bolts. The side view cross-section of the first and second arc-shaped pieces is semi-circular. Protrusions are evenly distributed on the inner walls of the first and second arc-shaped pieces. Under the action of the fixing bolts, the first and second arc-shaped pieces are fixed to each other, keeping them in a closed state. Because the first and second arc-shaped pieces are located inside the housing, the possibility of damage is avoided.

[0014] Preferably, the limiting structure includes a first washer, a rod, a second washer, a third washer, a first through hole, and a second through hole. The first washer is disposed on one side of the first arc-shaped piece and the second arc-shaped piece. The second washer is disposed on one side of the first washer, and the third washer is disposed on one side of the second washer. The first through hole is uniformly penetrated through the interior of the third washer, and the second through hole is uniformly penetrated through the interior of the second washer. The rod passes through both the first through hole and the second through hole. When the first washer is moved to one side of the second washer, the first washer causes the rod to pass through the interior of the second through hole. At this time, when the third washer is moved to one side of the second washer and pressed, the rod passes through the interior of the first through hole.

[0015] Preferably, one end of the insertion rod is fixedly connected to one side of the first washer, and the first, second, and third washers form a sliding structure with the cable body. Under the action of the first, second, and third washers, a blocking effect can be effectively achieved to limit the position of the first and second arc-shaped pieces, thereby fixing the position of the cable body and preventing the cable body from extending too far into the housing or being pulled too far out of the housing.

[0016] Preferably, the protective structure includes a protective shell, a movable groove, a reset plate, a snap-fit ​​groove, a snap-fit ​​plate, a reset spring, and an elastic rope. The protective shell is disposed on the outside of the machine head. Movable grooves are formed on both sides of the interior of the protective shell. A reset plate is disposed inside each movable groove. A reset spring is evenly distributed at one end of each reset plate, and a snap-fit ​​plate is fixed to the other end of each reset plate. A snap-fit ​​groove is formed inside each end of the snap-fit ​​plate inside the machine head. An elastic rope is fixed to the bottom end of the protective shell. Moving the protective shell to the outside of the machine head and pushing it causes the snap-fit ​​plate to move into the movable groove. Under the elastic force of the reset spring, the reset plate pushes the snap-fit ​​plate into the snap-fit ​​groove, thereby fixing the protective shell to the outside of the machine head and preventing collisions.

[0017] Preferably, the snap-fit ​​plate and the machine head form an engaging structure through snap-fit ​​grooves, and the end of the elastic rope away from the protective shell is fixedly connected to the outer wall of the machine shell. Under the action of the elastic rope, the protective shell is prevented from being lost. Pulling the protective shell, under the squeezing action of the machine head, causes the snap-fit ​​plate to move to the outside of the snap-fit ​​groove, thereby separating the protective shell and the machine head from each other.

[0018] The advantages of the concealed cable fixing structure provided by this utility model are as follows:

[0019] By incorporating a fixing mechanism, the first and second arc-shaped plates are semi-circular inside, and their inner walls are uniformly provided with protrusions. When the first and second arc-shaped plates rotate to align, the protrusions sink into the outer sheath of the cable body, allowing the first and second arc-shaped plates to be firmly clamped to the outside of the cable body. Under the action of fixing bolts, the first and second arc-shaped plates are fixed to each other, keeping them in a closed state. Because the first and second arc-shaped plates are located inside the housing, the possibility of damage is avoided, thus realizing the function of easy fixing of the device and improving the applicability of the concealed cable fixing structure in use.

[0020] By incorporating a connecting structure, the plug is placed on the outside of the cable body, allowing it to move to the appropriate position. When the plug is inserted into the housing, it moves the connecting bolt to the inside of the docking platform. With the cooperation of the connecting bolt and the docking platform, the plug and the housing are fixed together. The embedded inlet reduces the risk of damage to the connecting bolt, enabling the device to be easily disassembled and assembled, thereby improving the convenience of using the concealed cable fixing structure.

[0021] By setting a limiting structure, the first pad is moved to one side of the second pad, and the first pad drives the insertion rod through the inside of the second through hole. At this time, the third pad is moved to one side of the second pad, and the third pad is pressed to make the insertion rod pass through the inside of the first through hole. Under the action of the first pad, the second pad and the third pad, the blocking effect can be well played to limit the position of the first arc-shaped piece and the second arc-shaped piece, thereby fixing the position of the cable body and avoiding the problem of the cable body extending too much into the machine housing or being pulled out too much from the machine housing. This realizes the function of easy limiting of the device, thereby improving the stability of the built-in cable fixing structure during use.

[0022] By incorporating a protective structure, the protective shell is moved to the outside of the machine head. Pushing the protective shell causes the snap-fit ​​plate to move into the movable slot. Under the elastic force of the return spring, the return plate pushes the snap-fit ​​plate into the snap-fit ​​slot, thus fixing the protective shell to the outside of the machine head and preventing collisions. The elastic rope also prevents the protective shell from being lost. Pulling the protective shell causes the snap-fit ​​plate to move to the outside of the snap-fit ​​slot under the squeezing action of the machine head, thereby separating the protective shell from the machine head. This device achieves its protective function and improves the safety of the concealed cable fixing structure during use. Attached Figure Description
