[0044] It should be noted that, in the embodiment of the present invention, when the gate member 220 is in the first position, the gate member 220 blocks the gate passage 215; when the gate member 220 is in the second position, the gate member 220 releases the blocking of the gate passage 215; the gate spring 230 is used to drive the gate member 220 to move toward the first position; wherein, the gate bracket 210, the gate member 220 and the gate spring 230 are configured as a split structure, and the projection length of the part of the gate spring 230 that cooperates with the gate member 220 on the gate member 220 is greater than the outer side of the gate member 220 The distance from the wall to the center line of the gate member 220 is a split structure of the gate bracket 210, the gate member 220 and the gate spring 230, which simplifies the structure, facilitates manufacturing, reduces costs, and can be easily disassembled, thereby improving the maintainability and replaceability of the spring-type gate components; moreover, the projection length of the partial structure of the gate spring 230 that cooperates with the gate member 220 on the gate member 220 is greater than the center line length of the gate member 220, which can increase the stability and reliability of the closing force, and ensure that the spring-type gate assembly can always maintain good sealing performance and operating efficiency during operation.

[0045] It is understandable that, referring to Figures 3 to 5In the embodiment of the utility model, the gate spring 230 includes a spiral rod segment 231 and a driving rod segment 232 connected to the spiral rod segment 231. The spiral rod segment 231 is detachably fixed to the gate bracket 210 through a first positioning structure, and the driving rod segment 232 is detachably fixed to the gate member 220 through a second positioning structure.

Through the above-mentioned arrangement, by setting the push boss 223 and the corresponding recessed position, especially the first concave curved surface, the refueling gun can be inserted or pushed more easily. For example, when inserting or pushing, the concave curved surface provides additional space to make the insertion and pushing smoother. By increasing the thickness at the push boss 223 corresponding to the first concave curved surface, the durability of the area is enhanced, thereby extending the service life of the gate member 220.

3. The spring gate assembly according to claim 2, characterized in that: The first positioning structure is a first positioning groove (214) provided on the gate bracket (210), a first positioning channel (213) is provided at the bottom of the first positioning groove (214), a spiral region of the spiral rod segment (231) is located in the first positioning groove (214), and one end of the spiral rod segment (231) is inserted into the first positioning channel (213); The bottom of the first positioning groove (214) is used to support the spiral rod segment (231) so as to limit the spiral rod segment (231) from moving in a first direction; the opposite side walls of the first positioning groove (214) are abutted against the opposite sides of the spiral rod segment (231) so as to limit the spiral rod segment (231) from moving relative to the gate bracket (210) in a second direction; and the first positioning channel (213) is used to limit the spiral rod segment (231) from detaching from the gate bracket (210) in the second direction.

4. The spring gate assembly according to claim 3, characterized in that: The rod portion at one end of the spiral rod segment (231) is arranged obliquely to the spiral region of the spiral rod segment (231), and the vertical distance between the two end surfaces on the rod portion at one end of the spiral rod segment (231) is greater than the maximum width of the first positioning channel (213).

5. The spring gate assembly according to claim 3, characterized in that: There are two spiral rod segments (231), and there are two groups of the first positioning structures. The two groups of the first positioning structures are arranged at intervals, and the two groups of the first positioning structures are matched with the two spiral rod segments (231) in a one-to-one correspondence; Wherein, the two opposite ends of the two spiral rod segments (231) are respectively fixedly connected to the opposite two sides of the driving rod segment (232).

6. The spring gate assembly according to claim 2, characterized in that: The second positioning structure comprises two positioning bosses, which are arranged at intervals and cooperate with the inner surface of the gate member (220) to form a second positioning groove (222), the second positioning groove (222) is inserted and cooperated with the driving rod segment (232), and the two positioning bosses cooperate with the opposite sides of the driving rod segment (232) one by one to limit the movement of the driving rod segment (232) in the second direction relative to the gate member (220).

7. The spring gate assembly according to claim 1, characterized in that: The gate spring (230) is a torsion spring.

8. The spring gate assembly according to claim 1, characterized in that: The gate bracket (210) is provided with a plurality of first positioning portions (2192), the plurality of first positioning portions (2192) are arranged at intervals around the outer wall of the gate bracket (210), and the first positioning portions (2192) arrange the gate bracket (210) along a first direction.

9. A secondary gate unit, characterized in that: A spring gate assembly comprising any one of claims 1 to 8.
