Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Example 1

[0039] See also Figure 1-Figure 2 The utility model provides the following technical solutions: a charging gun, including a charging gun body 1, a charging head 2 fixed to the head of the charging gun body 1 and a charging cable 3, the charging cable 3 is plugged into the charging gun body 1 from the rear, and also includes a fixing mechanism 4, and the fixing mechanism 4 includes: a fixing cover 41 and a clamping block 42.

[0040] Further, by Figure 1 and Figure 2 As shown, the fixing cover 41 is detachably fixed to the tail of the charging gun body 1, and a wire outlet hole 411 for the charging cable 3 to pass through is opened on the fixing cover 41, and at least two clamping blocks 42 are installed in the fixing cover 41 at equal intervals along the circumferential direction for clamping the charging cable 3. Therefore, when in use, the charging cable 3 is passed through the wire outlet hole 411 and the inner space of multiple clamping blocks 42 and then inserted into the charging gun body 1 from the tail, and the charging cable 3 is clamped by multiple clamping blocks 42 to ensure the stability of the charging cable 3.

[0041] Preferably, by Figure 1 and Figure 2 As shown, in the present embodiment, arc-shaped clamping grooves 421 are provided on opposite surfaces of the plurality of clamping blocks 42. The plurality of clamping blocks 42 clamp the charging cable 3 by means of the arc-shaped clamping grooves 421. The arc-shaped clamping grooves 421 can match the outer arc surface of the charging cable 3, and can better clamp the charging cable 3, thereby ensuring the stability of the charging cable 3.

[0042] Preferably, by Figure 1 and Figure 2As shown, in this embodiment, the fixing mechanism 4 also includes: a wire ring 43, a first flip connecting arm 44 and a second flip connecting arm 45. The wire ring 43 is located in the fixing cover 41, and the charging cable 3 passes through the wire ring 43 and is tightly fitted with the inner wall of the wire ring 43. One end of the first flip connecting arm 44 is hinged to the fixing cover 41, and the other end is hinged to the clamping block 42. One end of the second flip connecting arm 45 is hinged to the wire ring 43, and the other end is hinged to the first flip connecting arm 44. When an external force pulls the charging cable 3, the charging cable 3 will drive the wire ring 43 to move through friction, and the wire ring 43 drives the second flip connecting arm 45 to flip and move. The second flip connecting arm 45 pulls the first flip connecting arm 44 to flip inward, so that the multiple clamping blocks 42 further clamp the charging cable 3 to prevent the charging cable 3 and the charging gun body 1 from loosening, thereby greatly improving the safety of use.

[0043] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the fixing mechanism 4 also includes: a fixing block 46, a mounting rod 47 and a reset spring 49. A plurality of fixing blocks 46 are fixed on the wire loop 43 at equal intervals along the circumferential direction. The mounting rod 47 is fixed in the fixing cover 41 and passes through the fixing block 46. A limiting disk 48 is fixed on the protruding end of the mounting rod 47. The reset spring 49 is sleeved on the mounting rod 47 and is located between the limiting disk 48 and the fixing block 46. In the initial state, due to the presence of the reset spring 49, the wire loop 43 is located in an inner position, and sufficient moving space is reserved for the wire loop 43. When an external force pulls the charging cable 3, the charging cable 3 will drive the wire loop 43 to move through friction, and further clamp the charging cable 3 through a plurality of clamping blocks 42. The mounting rod 47 is used to realize the installation of the wire loop 43, and is also used to guide the wire loop 43 to ensure the stability of the wire loop 43.

[0044] Optionally, by Figure 1 and Figure 2 As shown, in the present embodiment, the tail end of the charging gun body 1 has an external thread, and the fixing cover 41 has an internal thread. The fixing cover 41 is installed at the tail end of the charging gun body 1 by screwing, which is convenient for the installation and removal of the fixing cover 41. In theory, the fixing cover 41 can be fixed by other conventional fixing methods, such as bolts, clamping, etc., and installed by screwing, which not only has the effect of stable installation, but also facilitates the removal of the fixing cover 41.

[0045] Example 2

[0046] Preferably, by Figure 1 and Figure 2As shown, in this embodiment, the fixing mechanism 4 also includes: a rubber sealing ring 413, which is fixed to the inner wall of the fixing cover 41. When the fixing cover 41 is fixed to the tail of the charging gun body 1, the tail end of the charging gun body 1 squeezes the rubber sealing ring 413 to improve the sealing of the fixing cover 41 and prevent rainwater from entering the fixing cover 41 or the charging gun body 1.

[0047] Example 3

[0048] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the circumferential surface of the fixed cover 41 has anti-skid patterns, which can increase the friction between the hand and the outer wall of the fixed cover 41, making it more convenient and stable to rotate the fixed cover 41.

[0049] Example 4

[0050] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: a flexible lining 422, which is bonded and fixed to the inner wall of the arc-shaped clamping groove 421. In addition, anti-slip ridges 423 are evenly distributed on the inner wall of the flexible lining 422. When multiple clamping blocks 42 clamp the charging cable 3, the flexible lining 422 will shrink. The flexible lining 422 has flexibility and anti-slip effects, thereby ensuring the stability and safety of the charging cable 3. The flexible lining 422 can be made of a material with better flexibility, such as rubber, silicone, etc., preferably silicone, because silicone not only has better flexibility, but also has the characteristic of high temperature resistance.

[0051] Example 5

[0052] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, it also includes: a rubber guide ring 412, the rubber guide ring 412 is fixed in the wire outlet hole 411, and the rubber guide ring 412 has a truncated cone-shaped through hole 4121, the larger end of the through hole 4121 faces the charging gun body 1, and the structural form of the through hole 4121 makes it easy for the charging cable 3 to pass through the through hole 4121, and after the charging cable 3 passes through the through hole 4121, the through hole 4121 will expand, and the inner wall of the through hole 4121 is tightly fitted to the outer wall of the charging cable 3, further improving the sealing performance and preventing rainwater from entering the fixed cover 41 from the through hole 4121.

[0054] Working principle and use process of the utility model: When the charging gun body 1 of the utility model is used, the charging cable 3 is passed through the outlet hole 411 of the fixing cover 41 and the wire ring 43 and then plugged into the charging gun body 1 from the tail, and the charging cable 3 is clamped by multiple clamping blocks 42 to ensure the stability of the charging cable 3;

[0055] When an external force pulls the charging cable 3, the charging cable 3 will drive the wire ring 43 to move through friction, and the wire ring 43 drives the second flip connecting arm 45 to flip and move, and the second flip connecting arm 45 pulls the first flip connecting arm 44 to flip inward, so that the multiple clamping blocks 42 further clamp the charging cable 3, avoiding the loosening of the charging cable 3 and the charging gun body 1, which greatly improves the safety of use;

[0056] In addition, when the fixing cover 41 is fixed to the tail of the charging gun body 1, the tail end of the charging gun body 1 squeezes the rubber sealing ring 413, which cooperates with the rubber guide ring 412 to improve the sealing of the installation of the fixing mechanism 4 and prevent rainwater from entering the fixing cover 41 or the charging gun body 1.
