DETAILED DESCRIPTION

[0022] In order to further understand the utility model content, characteristics and effects of the utility model, the following examples are given, and the details are described as follows with the help of the drawings.

[0023] As Figures 1 to 7 shown, the utility model embodiment provides a locking mechanism of quick connecting cable for charging pile, including charging pile 1, the back of charging pile 1 is provided with notch 2, the back of charging pile 1 is detachably connected with baffle 3 located on the outside of notch 2, terminal post 4 is fixedly installed in the inside of notch 2, pressing plate 5 is arranged in the inside of notch 2, and pressing plate 5 is connected with charging pile 1 through locking mechanism.

[0024] Further, the locking mechanism includes guide rod 6, guide rod 6 is fixedly installed on the inner wall of notch 2, angle plate 7 is movably sleeved on guide rod 6, pressing plate 5 is fixedly connected on angle plate 7, toothed plate 9 is fixedly installed on both sides of the inner wall of notch 2, bolt 8 is movably inserted on angle plate 7, one end of bolt 8 is fixedly connected with pull handle 10, the other end of bolt 8 is fixedly connected with clamping block 11, and clamping block 11 is movably clamped on toothed plate 9.

[0025] When the staff puts the terminal loop on the cable on terminal post 4, pressing plate 5 can be pushed to press on the top of the terminal loop, and clamping block 11 is clamped on toothed plate 9 at the same time, so that the upward movement of pressing plate 5 and angle plate 7 can be avoided, and the terminal loop can be locked and fixed on terminal post 4, which facilitates the staff to install the terminal.

[0026] Further, the outer surface of bolt 8 movably sleeves spring 12, and both ends of spring 12 are fixedly connected with pull handle 10 and angle plate 7 respectively.

[0027] By setting spring 12 in the stretched state, due to the elastic recovery effect of spring 12, clamping block 11 will have a tendency to move close to toothed plate 9, so that clamping block 11 can stably maintain the clamping effect with toothed plate 9, and then the stable locking state of pressing plate 5 to the terminal loop is realized.

[0028] Further, frame body 13 is fixedly installed on the inner wall of notch 2, screw rod 14 is screw-connected on frame body 13, rotating block 15 is fixedly installed on the top of screw rod 14, and clamping plate 16 is rotatably connected to the bottom of screw rod 14.

[0029] By rotating the rotating block 15, the screw rod 14 can drive the clamping plate 16 to move downward, so that the bus cable can be clamped, and the stable state after the cable is connected is further improved.

[0030] Further, the bottom of the clamping plate 16 is fixedly provided with a rubber pad 17.

[0031] Through the design of the rubber pad 17, the cable skin can be well protected when clamping the cable, so as to avoid damage to the cable skin caused by pressing and clamping, and affect the use safety.

[0032] Further, the baffle 3 is fixedly provided with a sealing pad 18 which is attached to the surface of the charging pile 1.

[0033] Through the design of the sealing pad 18, the sealing effect of the slot 2 can be further improved.

[0034] The working principle and use process of the utility model are as follows:

[0035] Firstly, the staff puts the connecting ring on the cable on the connecting column 4, and then pushes the pressing plate 5 to move close to the connecting ring, so as to drive the angle plate 7 in the locking mechanism to move, thereby enabling the clamping block 11 to move along the surface of the tooth plate 9; when the pressing plate 5 locks the connecting ring, the clamping block 11 will keep the clamping state with the tooth plate 9 due to the elastic recovery of the spring 12, so as to realize the locking of the cable, which is convenient and fast; then the rotating block 15 can be rotated to drive the screw rod 14 to move downward, so as to clamp the bus cable, further improve the stable state after the cable is connected, and after the connection is completed, the baffle 3 is installed on the back of the charging pile 1 to seal the slot 2.

[0036] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
