[0021] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. Embodiment

[0022] Refer to Figures 1 to 4 , in the embodiment of the present utility model, a DC charging gun convenient for installation includes a charging gun body 1 and a socket 18. A charging plug 6 is provided at the top end of the charging gun body 1. The setting of the charging plug 6 can facilitate the fast charging process of the DC charging gun.

[0023] A handle 3 is provided at the inclined part of the first connecting block 2. The setting of the handle 3 can facilitate the taking and placing of the charging gun, thereby facilitating the use of the DC charging gun.

[0024] A first connecting block 2 is provided at the top of the charging gun body 1. A display 4 is provided at the left end of the top of the first connecting block 2, and a micro switch 5 is provided at the top of the first connecting block 2 on one side of the handle 3. The setting of the display 4 can facilitate the display of the power supply degree of the DC charging gun, and the setting of the micro switch 5 can facilitate the control of the power supply process of the DC charging gun.

[0025] A power supply tail seat 9 is provided at the tail end of the charging gun body 1. An insertion ring 10 is provided at the end of the power supply tail seat 9. A plurality of connection holes 13 are equidistantly opened inside the insertion ring. Both ends of the connection hole 13 are connected to a second connection block 14 through an elastic connection component. An insertion protrusion 15 is fixedly installed on the second connection block 14. The hemispherical part at the bottom of the insertion protrusion 15 is arranged outside the insertion ring 10. When the insertion seat 18 is inserted into the insertion ring 10, the inner wall of the insertion seat 18 presses the insertion protrusion 15 to move inward into the connection hole 13. The insertion protrusion 15 synchronously drives the second connection block 14 to move downward. The second connection block 14 drives the elastic connection component to move inward and generate an elastic force. The elastic force can realize the reset process of the insertion protrusion 15, so as to facilitate the stable connection between the insertion seat 18 and the insertion ring 10.

[0026] A charging insertion hole 12 is opened inside the power supply tail seat 9 located inside the insertion ring 10.

[0027] A charging insertion post 20 is provided at the center of the insertion seat 18. During the mutual insertion process of the insertion seat 18 and the power supply tail seat 9, the charging insertion post 20 is synchronously inserted into the charging insertion hole 12, so as to realize the power supply between the power supply tail seat 9 and the insertion seat 18.

[0028] A plurality of insertion grooves 19 are equidistantly opened on the inner wall of the insertion seat 18 located outside the charging insertion post 20. When the insertion grooves 19 equidistantly opened on the inner wall of the insertion seat 18 move to the insertion protrusion 15, the elastic force pushes the insertion protrusion 15 into the insertion groove 19, so as to realize the tight connection between the insertion seat 18 and the power supply tail seat 9, and facilitate the disassembly and rapid installation between the insertion seat 18 and the power supply tail seat 9.

[0029] A cable connection tail seat 21 is provided at the tail end of the insertion seat 18. A power supply cable 22 is installed on the cable connection tail seat 21. The setting of the power supply cable 22 can realize the power supply to the insertion seat 18.

[0030] A rubber gasket 11 is provided on the power supply tail seat 9 on one side of the insertion ring 10. When the insertion seat 18 is inserted into the insertion ring 10, the rubber gasket 11 seals the opening between the power supply tail seat 9 and the insertion seat 18, so as to realize the sealing of the connection between the cable and the power supply tail seat 9.

[0031] The elastic connection component includes a connecting rod 16 fixedly connected to both ends of the connection hole 13. The connecting rod 16 is slidably connected to the second connection block 14. A connection spring 17 is sleeved and installed on the connecting rod 16 inside the second connection block 14. During the process of inserting the plug socket 18 into the plugging ring 10, the plugging protrusion 15 moves inward under the extrusion of the plug socket 18. The plugging protrusion 15 synchronously drives the second connection block 14 to move inward, and the connection spring 17 compresses to generate elastic force. When the plugging protrusion 15 moves to the plugging groove 19, the elastic force pushes the plugging protrusion 15 into the interior of the plugging groove 19, so as to realize the quick installation and connection processing between the plug socket 18 and the power supply tail seat 9, and further facilitate the quick installation processing of the DC charging gun. Embodiment

[0032] In another embodiment of the present invention, the difference between this embodiment and the above-mentioned embodiment is that a connecting line 7 is provided at the bottom of the charging gun body 1, and a dust-proof sleeve 8 for sealing the charging plug 6 is provided at the end of the connecting line 7. By manually inserting the dust-proof sleeve 8 outside the charging plug 6, the dust-proof treatment of the charging plug 6 can be realized, which is convenient for the power supply treatment of the charging plug 6.

[0033] The working principle of the present invention is as follows: The present invention inserts the plug socket 18 onto the plugging ring 10 at the end of the power supply tail seat 9. The inner wall of the plug socket 18 squeezes the plugging protrusion 15 into the connection hole 13. The plugging protrusion 15 pushes the second connection block 14 to move inward, and the second connection block 14 squeezes the connection spring 17 to compress and generate elastic force. When the plugging groove 19 opened on the inner wall of the plug socket 18 moves to the plugging protrusion 15, the elastic force pushes the second connection block 14 to move outward, and the second connection block 14 drives the plugging protrusion 15 to insert into the plugging groove 19. The charging plug post 20 provided inside the plug socket 18 inserts into the charging plug hole 12, thus realizing the quick sealing plugging processing between the plug socket 18 and the power supply tail seat 9, further facilitating the installation processing of the DC charging gun and the disassembly and transportation processing of the DC charging gun.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
