[0043] The following will describe in detail some embodiments of the present utility model with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0044] See Figures 1 to 8, the box interface connector provided by the embodiment of the present utility model includes a connection box 100 and a plurality of connectors 200; the connection box 100 includes an upper cover 110 and a box body 120, the upper cover 110 covers the box body 120, and the bottom wall of the box body 120 is provided with conical shafts 121 equal in number to the connectors 200, and the sizes of each of the conical shafts 121 are different. The upper cover 110 is provided with locking holes 111 corresponding to the conical shafts 121 one by one, and the inner wall of the locking holes 111 is provided with a first locking structure, and the sizes of the first locking structures in each of the locking holes 111 are different; the connectors 200 are provided with conical holes 210, and the outer walls are provided with a second locking structure, and the sizes of the second locking structures of each of the connectors 200 are different, and the sizes of the conical holes 210 of each of the connectors 200 are different; the connectors 200 pass through the corresponding locking holes 111, the conical shafts 121 are inserted into the corresponding conical holes 210, and the first locking structure is clamped with the corresponding second locking structure.

[0045] Specifically, referring to Figure 1 , Figure 2 and Figure 8 , the box body 120 is provided with a cavity, and the upper cover 110 covers the opening end of the cavity. Referring to Figure 8 , the outer diameter of the conical shaft 121 gradually decreases from the end close to the bottom wall of the box body 120 to the end close to the upper cover 110; referring to Figure 7 , the outer diameter of the conical hole 210 gradually decreases from the end close to the bottom wall of the box body 120 to the end close to the upper cover 110. The different sizes of each conical shaft 121 may mean that the maximum outer diameters of each conical shaft 121 are different; or, the slopes of the outer walls of each conical shaft 121 are different; or, the maximum outer diameters and the slopes of the outer walls of each conical shaft 121 are different. Correspondingly, the sizes of the conical holes 210 are designed according to the sizes of the conical shafts 121, and since the designed sizes of each conical shaft 121 are different, the designed sizes of each conical hole 210 are also different. Further, the height of the conical shaft 121 is less than or equal to the height of the side wall of the box body 120. The conical shaft 121 and the conical hole 210 cooperate to achieve a sealed connection; wherein, the seal between the conical shaft 121 and the conical hole 210 is a conical surface seal, and the sealing effect is achieved through the contact between the two conical surfaces; when the two conical surfaces are fitted, due to the relatively small contact area, the pressure per unit area is large, thus generating a sealing effect.

[0046] The connection box 100 includes a box body 120 and an upper cover 110, which plays a supporting role for the conical shaft 121, and the connection box 100 is provided with a locking hole 111. When using this box interface connector, the connection box 100 communicates with the external pipeline. After the joint 200 passes through the locking hole 111, the conical shaft 121 is inserted into the conical hole 210 to achieve conical surface sealing. The cooperation between the conical shaft 121 and the conical hole 210 realizes the sealed connection between the joint 200 and the connection box 100; moreover, because the sizes of each conical shaft 121 are different and the sizes of each conical hole 210 are also different, each conical shaft 121 can only be inserted and matched with the conical hole 210 adapted to its size, so the anti-fooling function is realized, and the problem of incorrect pipeline connection is avoided. Rotating the joint 200 makes the first locking structure of the locking hole 111 engage with the second locking structure of the joint 200, realizing the positioning of the joint 200 and the connection box 100 and avoiding the joint 200 from falling off; moreover, because the first locking structure engages with the second locking structure, there is no need to rotate the pipeline multiple times, avoiding the problem of pipeline distortion; in addition, because the sizes of each first locking structure are different and the sizes of each second locking structure are also different, each second locking structure can only be locked with the first locking structure adapted to its size, so the anti-fooling function is further realized, and the problem of incorrect pipeline connection is avoided.

[0047] The shape and structure of the box interface connector will be described in detail as follows:

[0048] In an alternative embodiment of the present invention, the first locking structure includes a buckle 112, and the widths of the buckles 112 of each locking hole 111 are different; the second locking structure includes a card slot 220, and the widths of the card slots 220 of each joint 200 are different, and the buckle 112 is engaged with the corresponding card slot 220.

[0049] Specifically, referring to Figure 3 and Figure 4 , the buckle 112 protrudes from the inner wall of the locking hole 111, and a guiding structure extends outward from the side wall of the buckle 112, facilitating the sliding of the buckle 112 into the card slot 220 to engage with the card slot 220.

[0050] The different widths of each buckle 112 result in different sizes of each first locking structure; the different widths of each card slot 220 result in different sizes of each second locking structure. By the way of engaging the buckle 112 with the card slot 220, the installation and disassembly methods are simple, and there is no need to rotate the pipeline multiple times when locking, avoiding the problem of pipeline distortion.

[0051] In an alternative embodiment of the present invention, the card slot 220 includes a guiding section 221 and a locking section 222, and one end of the guiding section 221 communicates with the locking section 222 at an angle; the buckle 112 is engaged with the locking section 222.

[0052] Specifically, in this embodiment, the guide section 221 is perpendicular to the locking section 222, and the end of the guide section 221 away from the locking section 222 is open. After the buckle 112 slides into place from the opening of the guide section 221, the user rotates the joint 200 to slide the buckle 112 into the locking section 222, so that the two are engaged with each other.

[0053] The guiding section 221 enables the buckle 112 to enter the slot 220 , and the locking section 222 enables the buckle 112 to be engaged with the slot 220 .

[0054] In an optional solution of the embodiment of the utility model, two slots 220 and two buckles 112 are provided, and the locking sections 222 of the two slots 220 extend along the locking direction of the connector 200; the two buckles 112 are respectively engaged with the locking sections 222 of the corresponding two slots 220.

[0055] Specifically, the directions of the two locking sections 222 are consistent.

[0056] Two of the slots 220 and the buckles 112 are provided to enhance the locking effect and reduce the rotation angle of the connector 200 .

[0057] In an optional solution of the embodiment of the utility model, the locking section 222 and the guiding section 221 have a smooth transition.

[0058] Specifically, see Figure 6 The locking section 222 and the guiding section 221 are connected via an arc surface transition.

[0059] The locking section 222 and the guiding section 221 have a smooth transition, which improves the user experience.

[0060] In the optional scheme of the embodiment of the utility model, see Figure 6 and Figure 7 The connector 200 is further provided with a hose connector 230 , one end of the tapered hole 210 is connected to the tapered shaft 121 , and the other end is communicated with the hose connector 230 .

[0061] Specifically, in this embodiment, there are five connectors 200, locking holes 111 and tapered shafts 121, and the five tapered shafts 121 are spaced apart along the length and width directions of the box body 120. The five locking holes 111 are arranged in a one-to-one correspondence with the five tapered shafts 121; the five connectors 200 pass through the five locking holes 111 in a one-to-one correspondence.

[0062] The hose connector 230 is used to connect with a pipeline.

[0063] In an alternative embodiment of the present utility model, the connector 200 includes a first connecting portion 240 and a second connecting portion 250. The first connecting portion 240 is connected to the second connecting portion 250. The outer wall of the first connecting portion 240 is provided with a second locking structure. The second connecting portion 250 is provided with a hose connector 230. The tapered hole 210 penetrates through the first connecting portion 240 and the second connecting portion 250, and the tapered hole 210 communicates with the hose connector 230.

[0064] Specifically, the diameter of the second connecting portion 250 is greater than the diameter of the first connecting portion 240.

[0065] The first connecting portion 240 is connected to the tapered shaft 121 and is snap-fitted with the locking hole 111. The second connecting portion 250 is used for installing the hose connector 230.

[0066] In an alternative embodiment of the present utility model, the connector 200 includes two wrench ears 260. The two wrench ears 260 are symmetrically arranged at the top of the connector 200.

[0067] Specifically, the two wrench ears 260 are arranged opposite to each other, and the hose connector 230 is located between the two wrench ears 260.

[0068] The wrench ears 260 facilitate the user to rotate the connector 200, thereby facilitating the disassembly and assembly of the connector 200.

[0069] In an alternative embodiment of the present utility model, the wrench ears 260 are provided with anti-slip patterns.

[0070] Specifically, the anti-slip patterns are arranged as grooves recessed from the surface of the wrench ears 260; or, the anti-slip patterns are arranged as protrusions protruding from the surface of the wrench ears 260.

[0071] The anti-slip patterns increase the surface roughness of the wrench ears 260, which is beneficial for the user to rotate the connector 200.

[0072] In an alternative embodiment of the present utility model, the locking hole 111 is provided with a first marking structure, and the first marking structures of each locking hole 111 are different; the connector 200 is provided with a second marking structure, and the second marking structures of each connector 200 are different.

Alternatively, both the first identification structure and the second identification structure are set as digital labels, and each locking hole 111 is pasted with a digital label of a different number; correspondingly, each connector 200 is pasted with a digital label of a different number, and the digital labels of the matching locking holes 111 and connectors 200 are the same.

[0074] The setting of the first identification structure and the second identification structure further avoids the problem of incorrect pipeline connection.

[0076] The box interface connector includes a connector 200 and a connection box 100. The connection box 100 includes an upper cover 110 and a box body 120. The connector 200 realizes conical surface sealing with the conical shaft 121 on the bottom wall of the box body 120 through the conical hole 210, and at the same time, the cooperation between the two realizes the first anti-fooling operation of the connector 200 and the connection box 100. The connector 200 is snap-connected with the buckle 112 through the card slot 220 to realize the cooperation between the connector 200 and the connection box 100, and further realize the positioning of the connector 200 and the connection box 100 and the second anti-fooling.

[0077] The interface connector provides a stable and reliable pipeline connection method; prevents misconnection between multiple connectors 200 and connection boxes 100; improves the connection sealing performance between the connector 200 and the connection box 100, and reduces the rotation angle of the connector 200.
