[0023] In the specific implementation process, refer to Figure 4As shown, this utility model provides a charging gun. The anti-pull-out component includes a first mounting block 15. The first mounting block 15 is fixedly connected to the bottom outer wall of the charging head 3. A second mounting block 21 is disposed on one side of the first mounting block 15. A first mounting groove is opened on one side of the first mounting block 15. Two No. 3 springs 16 are fixedly installed inside one side of the first mounting groove.

Several connecting posts 19 are fixedly installed on one side of the sliding plate 23. A sealing plate 20 is fixedly sleeved on the inner circular wall of the first mounting groove. Several connecting posts 19 are opened on one side of the sealing plate 20. A positioning hole, the inner circular wall of the positioning hole is movably sleeved with the connecting column 19, one end of the connecting column 19 is fixedly installed with the second mounting block 21, a second mounting groove is opened on one side of the second mounting block 21, an electromagnet 22 is fixedly sleeved on the inner circular wall of the second mounting groove, the electromagnet 22 is electrically connected to the control system of the charging gun body 1, two guide rods 17 are fixedly installed on one side of the first mounting groove, the outer circular wall of the guide rod 17 is movably sleeved with the No. 3 spring 16, two guide holes are opened on one side of the slide plate 23, the guide holes are movably sleeved with the outer circular wall of the guide rod 17, and a limit piece 18 is fixedly installed on one end of the guide rod 17;

[0024] It should be noted that the above-mentioned charging gun body (first mounting block 15, third spring 16, guide rod 17, limiting plate 18, connecting post 19, sealing plate 20, second mounting block 21, electromagnet 22, and sliding plate 23) is a car charging gun disclosed in the existing publication number CN221366596U (first mounting block, third spring, guide rod, limiting plate, connecting post, sealing plate, second mounting block, electromagnet, and pressure plate). In this device, through the provided second mounting block, when in use, the operator inserts the charging gun body into the charging port of the electric vehicle. During this process, the second mounting block and the electromagnet will contact the surface of the electric vehicle, and then the first mounting block will move as the charging gun body moves. During this process, the pressure plate will compress the spring, and then the spring's rebound force will push the pressure plate and the connecting post to move. Then the connecting post pushes the second mounting block and the electromagnet to move, and keeps the electromagnet in contact with the electric vehicle. When the charging gun body is in use, the control system of the charging gun body energizes the electromagnet, which generates a magnetic force. The magnetic force of the electromagnet then attracts the charging gun body to the surface of the electric vehicle. At this time, the attraction force of the electromagnet keeps the charging gun body inserted into the charging port of the electric vehicle. If someone maliciously tries to pull out the charging gun body, the magnetic force of the electromagnet prevents the charging gun body from being easily pulled out. When the electric vehicle is fully charged, the control system of the charging gun body de-energizes the electromagnet. At this time, the electromagnet loses its magnetic force, and the operator can then pull the charging gun body out of the charging port of the electric vehicle. This achieves the effect of preventing the charging gun body from being maliciously pulled out during use. The various mechanisms in this device are the same as the working principle and operation mode of a previously disclosed car charging gun, which enables this device to effectively prevent the charging gun body from being maliciously pulled out during use through the electromagnet.

[0025] The working principle of this utility model is as follows: Press button 5, button 5 pushes one end of pressure plate 6 to lift, overcoming the elastic force of spring 7. Pressure plate 6 rotates through shaft 8, and the other end falls, acting on connecting block 9 and locking assembly, causing dust cover 4 to rise. Dust cover 4 is in the open state to expose charging head 3. Hold the charging gun body 1 and grip it through finger groove 2. The anti-slip pad on the inner wall of finger groove 2 increases friction to ensure stable grip. Align charging head 3 with the charging interface of electric vehicle or charging pile and insert it. After insertion, release button 5. Spring rises and causes dust cover 4 to press down to protect charging head during charging. If dust cover 4 needs to be replaced, simply press down on pressing post 11. Pressing post 11 falls and drives rotating plate 13 to retract around rotating rod 12 into fixed groove. Pull out locking post 10 to separate connecting block 9 and dust cover 4 from pressure plate 6. Conversely, dust cover 4 can be installed.

[0026] This charging gun has the following advantages: pressing button 5 controls the dust cover 4 to open or close automatically without manual operation, improving efficiency. After releasing button 5, spring 7 pushes the pressure plate 6 back, causing the dust cover 4 to press down, covering the charging head 3 and preventing foreign objects from entering or being accidentally touched, ensuring safety during the charging process. During charging, the locking component effectively prevents the charging head 3 from being accidentally pulled out, improving electrical safety. Simply pressing the pressing post 11 allows the dust cover 4 to be disassembled together with the connecting block 9 without the need for any tools, making it convenient for cleaning, maintenance, or replacement of dust covers of different specifications.

[0027] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
