Description

Technical Field

[0001] This utility model relates to the field of gun head structure technology, specifically a replaceable gun head structure. Background Technology

[0002] With the improvement of people's living standards and the current trend of advocating environmental protection, energy conservation, and a green ecological earth, electric vehicles are developing and growing stronger with the strong support of the country, and their applications are becoming more and more widespread. The charging guns that are matched with electric vehicles are also developing rapidly. Electric vehicles are charged through the charging gun cable.

[0003] Application number CN202322212947.6 discloses a charging gun with a quick-change nozzle, relating to the field of new energy vehicles, including an insulating shell and auxiliary components. When the nozzle body needs replacement after prolonged use, the quick-change nozzle locking assembly uses locking rods one and two to engage with a groove, causing a locking block to push along the mounting base from the outside in. During this pushing process, the insulating shell and the nozzle body are locked together. Simultaneously, a compression spring is compressed along with the locking block, and after compression, the threaded rod and clamping plate securely hold the locking block in place.

[0004] In practical use, this application relies on a threaded rod clamping method to fix the gun head body. Although this method is simple and easy to operate, the threaded connection is not secure. After long-term use, the threaded rod is prone to rusting and loosening, affecting the long-term reliability of the equipment. Utility Model Content

[0011] In a preferred embodiment, the present invention can be further configured such that: a sealing assembly is provided on the gun body, the sealing assembly includes a plug that is slidably sleeved on the outside of the gun head body and inserted into the gun body, and a retaining plate connected to the top of the gun body, the plug being engaged with the inside of the retaining plate.

[0012] In a preferred embodiment, the present invention can be further configured such that: both the top and bottom of the plug cavity are provided with slots, which are suitable for insertion of the outer buckle plate.

[0013] In a preferred embodiment, the present invention can be further configured such that: an annular groove is provided inside the plug, the annular groove is located outside the slot, and is movably engaged with the gun head body.

[0014] In a preferred embodiment, the present invention can be further configured such that: a plate sleeve is sleeved on the outer side of the card plate, and the inner side of the plate sleeve is fixedly connected to the outer wall of the gun body.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, the gun head body is connected to the gun body. At this time, the inner strip is engaged with the outer buckle plate, and the outer strip is engaged with the inner buckle plate. The spring presses against the gun head body outward to ensure that it is installed firmly. The engagement method ensures stable mechanical interlocking and guarantees that the device can operate reliably for a long time.

[0017] 2. In this utility model, when replacing the gun head body, first separate the plug from the gun body, then rotate the gun head body to separate the outer buckle plate from the inner strip, and at the same time separate the inner buckle plate from the outer strip. At this time, the gun head body loses its limit, and the spring pushes it out of the gun body, thereby completing the replacement operation. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0031] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0032] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a replaceable gun head structure.

[0033] Example 1:

[0034] Combination Figure 1-7 As shown, the present invention provides a replaceable gun head structure, including a charging mechanism 100 and a locking mechanism 200. The charging mechanism 100 includes a gun body 110 and a gun head body 120 that is movably connected to the gun body 110.

[0035] The locking mechanism 200 includes two inner strips 210 fixed to the top and bottom of the inner cavity of the gun body 110, two outer buckles 220 fixed to the top and bottom of the gun head body 120, two outer strips 230 fixed to the side walls of the gun head body 120, and two inner buckles 240 fixed to the side walls of the inner cavity of the gun body 110. The two outer buckles 220 are respectively engaged with the inner side of the two inner strips 210, and the two inner buckles 240 are respectively engaged with the outer side of the two outer strips 230.

[0036] Furthermore, the locking mechanism 200 also includes a spring 250, which is embedded inside the gun body 110 and fits against the inner end of the gun head body 120. The spring 250 can make the gun head body 120 more securely installed, and also facilitates the removal of the damaged gun head body 120 from the gun body 110.

[0037] Furthermore, the two outer buckle plates 220 and the two inner buckle plates 240 are equally spaced and arranged in a ring-shaped staggered pattern. The outer buckle plates 220 and the inner buckle plates 240 are both L-shaped and fit against the inner wall of the gun body 110. The shape and layout design of the outer buckle plates 220 and the inner buckle plates 240 enable the gun head body 120 to be stably inserted into the gun body 110.

[0038] Example 2:

[0039] Combination Figure 1 , 2 6 and Figure 7 As shown, based on Embodiment 1, the gun body 110 is provided with a sealing assembly 300. The sealing assembly 300 includes a plug 310 that is slidably sleeved on the outside of the gun head body 120 and inserted into the gun body 110, and a retaining plate 320 that is connected to the top of the gun body 110. The plug 310 is engaged with the inside of the retaining plate 320. The retaining plate 320 and the plug 310 cooperate to make the plug 310 firmly seal the port of the gun body 110.

[0040] Furthermore, the top and bottom of the inner cavity of the plug 310 are provided with slots 311, which are suitable for the outer buckle plate 220 to be inserted. The slots 311 provide conditions for the plug 310 to be fully inserted into the gun body 110.

[0041] Furthermore, the plug 310 has an annular groove 312 inside. The annular groove 312 is located outside the slot 311 and is movably engaged with the gun head body 120. By providing the annular groove 312, the plug 310 can be engaged with the gun head body 120, thereby improving the stability of the gun head body 120 during installation.

[0042] Example 3:

[0043] Combination Figure 1 , 2and Figure 6 As shown, in the above embodiment, a sleeve 400 is sleeved on the outer side of the card plate 320, and the inner side of the sleeve 400 is fixedly connected to the outer wall of the gun body 110. The sleeve 400 makes the card plate 320 more securely installed.

[0044] The working principle and usage process of this utility model are as follows: In the initial state, the gun head body 120 is connected to the gun body 110. At this time, the inner strip 210 is engaged with the outer buckle plate 220, and the outer strip 230 is engaged with the inner buckle plate 240. The spring 250 presses against the gun head body 120 outward to ensure its stable installation. When replacing, first separate the plug 310 from the gun body 110, then rotate the gun head body 120 to separate the outer buckle plate 220 from the inner strip 210, and at the same time separate the inner buckle plate 240 from the outer strip 230. At this time, the gun head body 120 loses its limit, and the spring 250 pushes it out of the gun body 110, thereby completing the replacement operation.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
