[0057] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0058] The embodiment of the utility model relates to a filling port device 100. Figure 1 , Figure 2 , Figure 3 As shown, the filling port device 100 includes: a housing 10 and a cover 20, wherein the housing 10 is provided with a channel 11 extending axially and penetrating the housing 10, and an opening communicating with the channel 11 is provided at the end of the housing 10. The cover 20 is provided with an external thread 201, and the housing 10 is provided with an internal thread 101, and the cover 20 is threadedly connected to the housing 10 and can be operated to open or close the opening. The cover 20 has a cover connecting portion 22 threadedly connected to the housing 10, and an outer flange portion 21 arranged around the outer periphery of the cover connecting portion 22. The filling port device 100 also includes: at least one first check portion 30 and a second check portion 40. The first check portion 30 has a check base 31 arranged on the outer flange portion 21, and a check body 32 arranged on the check base 31. The check base 31 at least partially protrudes axially toward the side where the cover connecting portion 22 is located, and is separated from the cover connecting portion 22. The second check portion 40 is arranged on the housing 10 and cooperates with the check body 32. The second check portion 40 has ratchet teeth 41, which are arranged outside the channel 11. The check body 32 is used to be inserted into the tooth groove 42 of the ratchet teeth 41 after the cover 20 and the housing 10 are screwed together and tightly closed, and the first check portion 30 can be operably removed from the cover 20 connected thereto. Specifically, if Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, when the filling port is initially sealed, the cover 20 is screwed onto the housing 10, the cover connection portion 22 is inserted into the channel 11, and the check body 32 is moved along the direction of the ratchet 41 by the cover 20. After the cover 20 seals the housing 10, the ratchet 41 clamps the check body 32, and the cover 20 cannot be reversely rotated to open the housing 10. When the cover 20 needs to be unscrewed, as shown in FIG. Figure 8 As shown, the first non-return portion 30 is torn off from the outer flange portion 21 , and the cover body 20 can be unscrewed only when the first non-return portion 30 is not stuck.

[0059] As can be seen from the above, since the first check portion 30 and the second check portion 40 are provided, and the second check portion 40 has ratchet teeth 41, after the cover 20 and the housing 10 are screwed together and tightly closed, the check body 32 of the first check portion 30 is stuck in the tooth groove 42 of the ratchet teeth 41, so that the cover 20 cannot be unscrewed from the housing 10. When it is necessary to open the filling port, the first check portion 30 needs to be disassembled, and the check body 32 is no longer stuck by the second check portion 40, and the cover 20 can be unscrewed from the housing 10. Therefore, when the first check portion 30 is disassembled, it can be clearly identified whether the valve cover of the valve used for the first time has been opened by someone.

[0060] Furthermore, if Figure 3 and Figure 4 As shown, the non-return base 31 is connected to the outer flange 21 through the first weakened rib 34. The first non-return portion 30 and the outer flange 21 are an integral part and are processed together. The first non-return portion 30 and the cover body 20 are connected as a whole through the first weakened rib 34. The first weakened rib 34 needs to be torn off to prevent the first non-return portion 30 from being separated from the cover body 20.

[0061] Furthermore, the first non-return portion 30 and the outer flange portion 21 are integrated, and there are a plurality of first non-return portions 30 , which are spaced apart around the outer circumference of the cover connecting portion 22 .

[0062] Alternatively, if Figure 3 As shown, there are two first check portions 30 , which are relatively spaced apart along the axis of the cover body 20 .

[0063] Furthermore, if Figure 3 As shown, the non-return base 31 has an embedding portion 311 embedded in the outer flange portion 21, and a support portion 312 connected to the embedding portion 311. The embedding portion 311 is connected to the outer flange portion 21 through a first weakened rib 34, and the non-return body 32 is arranged on the support portion 312.

[0064] Furthermore, if Figure 3As shown, the check body 32 is arranged on the side of the support portion 312 facing the cover connecting portion 22. The housing 10 has a flange 13, and a housing 10 connecting portion connected to the flange 13 and extending axially, and the housing 10 connecting portion is threadedly connected to the cover 20 connecting portion. The outer periphery of the port of the housing 10 connecting portion away from the flange 13 is provided with a ratchet 41.

[0065] In addition, if Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the check body 32 is a convex block. The check body 32 has a first check surface 321 and a first guide surface 322 that is at a first angle to the first check surface 321, and the ratchet 41 has a second check surface 411 and a second guide surface 412 that is at a second angle to the second check surface 411. When the cover 20 is screwed together with the housing 10, the second guide surface 412 cooperates with the first guide surface 322 to guide the cover 20; when the cover 20 is screwed together with the housing 10 and tightly closed, the first check surface 321 abuts against the second check surface 411. In the process of screwing the cover 20 onto the housing 10 for the first time, since the first check portion 30 is elastic, the check body 32 can be pushed outward when passing the tooth tip of the ratchet 41, thereby passing over the tooth tip of the ratchet 41, so that the cover 20 can continue to be smoothly screwed until it is locked. Specifically, the check body 32 has a first check surface 321 and a first guide surface 322 that is at a first angle to the first check surface 321, and the ratchet 41 has a second check surface 411 and a second guide surface 412 that is at a second angle to the second check surface 411. In the process of initially screwing the cover 20 onto the housing 10, such as screwing the cover in a clockwise direction as shown in the figure, the second guide surface 412 can provide guidance for the first guide surface 322 to allow the check body 32 to slide along the arrangement direction of the ratchet 41, that is, in a clockwise direction as shown in the figure, so that the cover 20 is screwed onto the housing 10. After the cover 20 and the housing 10 are screwed together and tightly closed, the first check surface 321 abuts against the second check surface 411, the second guide surface 412 abuts against the first guide surface 322, and the check body 32 is embedded in the tooth groove 42 of the ratchet 41. In order to allow the non-return body 32 to be driven by the cover body 20 to slide, the first guide surface 322 gradually moves away from the cover body 20 in the direction of the first non-return surface 321 .

[0066] In addition, if Figure 6 As shown, the ratio of the axial height h2 of the first check portion 30 protruding outside the outer flange portion 21 to the axial height h1 of the cover connecting portion 22 protruding outside the outer flange portion 21 is 1:4-1:6. Optionally, the ratio of the axial height h2 of the first check portion 30 protruding outside the outer flange portion 21 to the axial height h1 of the cover connecting portion 22 protruding outside the outer flange portion 21 is 1:5.

[0067] In another embodiment, a filling port device 200 is provided, such as Fig. 9 As shown, the structure of the filling port device 200 is similar to that of the first embodiment, and includes a shell 80 and a cover 90 . Fig.10 , Fig.11 , Fig.12 As shown, the second check portion 70 can be operably removed from the housing 80 to which it is connected. The housing 80 has a flange 82, and a housing 80 connection portion connected to the flange 82 and extending axially, and the housing 80 connection portion is threadedly connected to the cover 90 connection portion. The second check portion 70 is connected to the housing 80 connection portion through a second weakened rib 73, and the second check portion 70 and the housing 80 connection portion are separated by an annular cavity 74 into which the first check portion 60 is inserted. The ratchet 71 is arranged on the side of the second check portion 70 facing the housing 80 connection portion, and the check body 62 is arranged on the side of the check base 61 away from the cover connection portion 92. At this time, the second check portion 70 has a slight elasticity, and the check body 62 can push the first check portion 60 outward when passing the tooth tip of the ratchet 71, thereby passing over the tooth tip of the ratchet 71, so that the cover 90 can continue to be smoothly screwed to lock. Fig.13 , Fig.14 , Fig.15 , Fig.16 As shown, the non-return body 62 has a first non-return surface 621 and a first guide surface 622 which is at a first angle with the first non-return surface 621, and the ratchet 71 has a second non-return surface 711 and a second guide surface 712 which is at a second angle with the second non-return surface 711. In the process of initially screwing the cover 90 onto the housing 80, such as screwing the cover in a clockwise direction as shown in the figure, the second guide surface 712 can provide guidance for the first guide surface 622 to allow the non-return body 62 to slide along the arrangement direction of the ratchet 71, that is, in a clockwise direction as shown in the figure, so that the cover 90 is screwed onto the housing 80. After the cover 90 and the housing 80 are screwed together and tightly covered, the first non-return surface 621 abuts against the second non-return surface 711, the second guide surface 712 abuts against the first guide surface 622, and the non-return body 62 is embedded in the tooth groove 72 of the ratchet 71. In order to allow the non-return body 62 to be driven by the cover 90 to slide, the first guide surface 622 gradually moves away from the cover 90 in the direction of the first non-return surface 621. When the cover 90 needs to be opened, the second non-return portion 70 is removed from the connection portion of the housing 80, and the non-return body 62 is not limited by the second non-return portion 70, and the cover 90 can be rotated to open. In this structure, the first non-return portion 60 and the outer flange portion 91 can be formed as one piece and can be left intact from the outer flange portion 91. The non-return base 61 of the first non-return portion 60 protrudes from the outer flange portion 91 as a whole, rather than being partially embedded in the outer flange portion 91.

[0068] Since the first embodiment and the present embodiment correspond to each other, the present embodiment can be implemented in conjunction with the first embodiment. The relevant technical details mentioned in the first embodiment are still valid in the present embodiment, and the technical effects that can be achieved in the first embodiment can also be achieved in the present embodiment. In order to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in the present embodiment can also be applied in the first embodiment.

[0069] Yet another embodiment of the present embodiment further relates to a valve, which comprises: a filling port device as in any one of the above embodiments, and a valve core arranged in the housing.
