[0048] The valve protection box 20 of the utility model is mainly used in a tank container, such as a tank container 10. The valve protection box 20 is used to protect the valves on the tank body, thereby increasing the safety of the tank container during transportation.

[0049] See also Figure 1 and Figure 2 As shown, the valve protection box 20 of the embodiment of the utility model is used to protect the valves of the tank container 10.

[0050] The tank container 10 generally includes a tank body and a frame supporting the tank body. The valve member is generally arranged on the tank body of the tank container 10. For example, the valve member may be located at one side of the bottom of the tank body.

[0051] See also Figure 1 and Figure 2 The valve protection box 20 according to the embodiment of the utility model comprises a box body 100, a box cover 200 and a hinge component 300. The box body 100 is arranged at the valve of the tank container 10, and the box body 100 is provided with an operation port 110.

[0052] like Figure 2 As shown, the box body 100 may include a top plate and two side plates arranged at both ends of the top plate. The top end of each side plate is fixedly connected to the top plate, and the bottom end may be fixedly connected to the frame at the bottom of the tank container 10.

[0053] The top plate and the side plates may be fixedly connected by welding. Alternatively, the top plate and the side plates may be detachably fixedly connected by fasteners such as bolts.

[0054] The side panels and the frame can be fixedly connected by welding. Alternatively, the side panels and the frame can be detachably fixedly connected by fasteners such as bolts.

[0055] like Figure 2 As shown, the top plate, the two side plates and the frame form a shell structure with two openings, one of which is an operation port 110 and the other is a mounting port. The box body 100 can be mounted outside the valve member through a mounting cover.

[0056] In other embodiments, the box body 100 may further include a bottom plate. The bottom plate may be connected to the bottom ends of the two side plates. The bottom plate may be fixedly connected to a frame at the bottom of the tank container 10.

[0057] like Figure 2 As shown, the box cover 200 is hinged to one side of the box body 100, and is covered at the operation opening 110 so as to open or close the operation opening 110. Specifically, the box cover 200 can be hinged on the side of the top plate. Thereby the operator can flip the box cover 200 upwards to open the operation opening 110 or flip the box cover 200 downwards to close the operation opening 110.

[0058] In other embodiments, the box cover 200 may also be hinged to the side edge of the side plate of the box body 100. Alternatively, the box cover 200 may also be hinged to the side edge of the bottom plate of the box body 100.

[0059] The hinge component 300 is used to connect the box body 100 and the box cover 200 to achieve a hinged connection between the box body 100 and the box cover 200. Figure 1 As shown, there may be two hinge components 300 , and the two hinge components 300 are evenly distributed between the side edge of the top of the box body 100 and the box cover 200 .

[0060] In other embodiments, one or more hinge components 300 may be provided to connect the box body 100 and the box cover 200 according to the size of the valve protection box 20 .

[0061] See also Figure 3 and Figure 4 The hinge component 300 includes two chain bodies 310 of the same structure. Preferably, each chain body 310 is a casting and is integrally formed.

[0062] The two chain bodies 310 are detachably connected to the box body 100 and the box cover 200. The two chain bodies 310 are connected by a hinge shaft 320. The two chain bodies 310 are arranged on the box body 100 and the box cover 200 symmetrically.

[0063] like Figure 3 As shown, the two chains 310 can be rotationally symmetrical to each other. Figure 3 Taking the illustrated position as an example, of the two chain bodies 310 of each hinge component 300 , the left chain body 310 can overlap with the right chain body 310 after being horizontally rotated 180° toward the right side.

[0064] Similarly, Figure 4 Taking the illustrated position as an example, of the two chain bodies 310 of each hinge component 300 , the upper chain body 310 can overlap with the lower chain body 310 after being rotated 180° vertically downward toward the right side.

[0065] In the valve protection box 20 of the embodiment of the present application, the box cover 200 is hinged to the box body 100 through the hinge component 300. Since the hinge component 300 includes two chain bodies 310 with the same structure, the hinge component 300 can be manufactured in a standardized manner, which greatly saves the manufacturing and processing costs.

[0066] The two chain bodies 310 are detachably connected to the box body 100 and the box cover 200, respectively, so that the hinge component 300 is easily installed on the box body 100 and the box cover 200, and the installation efficiency is high. This effectively avoids the problem of large welding amount caused by the rotating shaft in the traditional connection method being integrally welded and fixed on the box body 100 and the box cover 200.

[0067] Since the two chain bodies 310 are arranged symmetrically, the box cover 200 will not be displaced after being opened and closed multiple times, making the hinged connection between the box cover 200 and the box body 100 more reliable. The valve protection box 20 of the present application has a simple structure, is easy to install and process, and has a good connection effect between the box cover 200 and the box body 100.

[0068] See also Figure 5In one embodiment, each chain body 310 includes a fixing plate 311 and a connecting plate 313, and the ends of the fixing plate 311 and the connecting plate 313 are connected. The ends of the fixing plate 311 and the connecting plate 313 are connected, and the two are at an angle to each other.

[0069] like Figure 5 As shown, the fixing plate 311 is provided with an assembly hole 312 for detachably connecting with the box body 100 or the box cover 200. By providing the assembly hole 312, the chain body 310 can be detachably connected with the box body 100 or the box cover 200 by fasteners such as bolts.

[0070] like Figure 5 As shown, the connecting plate 313 is provided with a connecting hole 314 for passing the hinge shaft 320. By providing the connecting hole 314, the hinge shaft 320 can be easily passed through to achieve the hinge connection between the two chain bodies 310.

[0071] See also Figure 6 and Figure 7 As shown, in one embodiment, the fixing plate 311 and the connecting plate 313 are vertically connected. By vertically connecting the fixing plate 311 and the connecting plate 313, the contact surface of the two connecting plates 313 when the two chain bodies 310 are hinged to each other can be larger, thereby improving the connection strength between the two chain bodies 310.

[0072] like Figure 5 As shown, the fixing plate 311 may be substantially in the shape of a strip plate. Each corner of the fixing plate 311 has an arc transition.

[0073] The connecting plate 313 may be substantially in the shape of a strip plate. Each corner of the connecting plate 313 has an arc transition.

[0074] Optionally, the fixing plate 311 and the connecting plate 313 are connected in an arc transition, so that the structure of each chain body 310 is smooth and easy to use.

[0075] See also Figure 5 In one embodiment, the end of the connecting plate 313 away from the fixing plate 311 is inclined toward the side of the fixing plate 311, so that the projection of the connecting plate 313 on the plane where the fixing plate 311 is located at least partially protrudes from the side of the fixing plate 311. Figure 3 As shown, the connecting plate 313 of each chain body 310 is inclined toward the side of the fixing plate 311, so that the chain body 310 on the box body 100 can partially protrude toward the box cover 200, and the chain body 310 on the box cover 200 can partially protrude toward the box body 100, thereby facilitating the hinged connection between the two chain bodies 310.

[0076] See also Figure 1The valve protection box 20 further includes a locking component 400 disposed between the box body 100 and the box cover 200. The locking component 400 is used to limit and fix the box cover 200 relative to the box body 100 when the box cover 200 closes the operation port 110, so that the box cover 200 remains in the position of closing the operation port 110.

[0077] like Figure 1 As shown, specifically, the locking component 400 includes a locking plate 410 and a locking ear plate 420, wherein the locking plate 410 is relatively fixedly connected to the box cover 200, and the locking ear plate 420 is rotatably connected to the box body 100. The locking ear plate 420 can be rotated to a locking position overlapped on the locking plate 410, so that the box cover 200 keeps closing the operation port 110.

[0078] When closing the box cover 200, the lock ear plate 420 is rotated to overlap the locking plate 410. At this time, since the lock ear plate 420 limits the outward and upward movement of the locking plate 410, the box cover 200 cannot be turned upward to open the operating port 110.

[0079] See also Figure 1 and Figure 8 As shown, in one embodiment, the lock ear plate 420 includes a first plate body 421, a second plate body 422 and a third plate body 423 connected to each other, the first plate body 421 is rotatably connected to the box body 100, and the second plate body 422 is perpendicular to the first plate body 421. The third plate body 423 is perpendicular to the second plate body 422 and an L-shaped limiting surface 424 is formed therebetween. When the lock ear plate 420 is in the locked position, the limiting surface 424 and two adjacent surfaces of the locking plate 410 are in contact with each other.

[0080] like Figure 1 As shown, when closing the box cover 200, the lock ear plate 420 is rotated to overlap the locking plate 410. At this time, the limiting surface 424 of the lock ear plate 420 is respectively in contact with the upper surface and the front side of the locking plate 410, preventing the locking plate 410 from moving outward and upward, so that the box cover 200 cannot be turned upward to open the operation opening 110. That is, through the mutual interference of the lock ear plate 420 and the locking plate 410, the box cover 200 can be kept in the position of closing the operation opening 110.

[0081] See also Figure 2In one embodiment, the locking plate 410 is provided with a first locking hole 411, and the locking ear plate 420 is provided with a second locking hole 425 corresponding to the first locking hole 411. When the locking ear plate 420 is in the locking position, the second locking hole 425 is coaxial with the first locking hole 411. When the box cover 200 is closed, the locking ear plate 420 is rotated to overlap the locking plate 410. At this time, the second locking hole 425 is coaxial with the first locking hole 411. By using a locking pin that is sequentially inserted into the first locking hole 411 and the second locking hole 425, the box cover 200 can be locked and fixed to the box body 100 when the box cover 200 is closed.

[0082] In this embodiment, by providing the first locking hole 411 and the second locking hole 425, the box cover 200 and the box body 100 can be locked and fixed, ensuring the reliable closing of the box cover 200. In particular, it effectively avoids the interference between the lock ear plate 420 and the locking plate 410 due to the shaking of the container during the transportation of the container, avoids the box cover 200 from being opened by mistake, and improves the safety of the valve protection box 20.

[0083] See also Figure 1 As shown, an embodiment of the present invention further provides a tank container 10, comprising a tank body and a frame supporting the tank body, and a valve protection box 20 as described in any of the above embodiments. The box body 100 can be fixedly connected to the frame.

[0084] It can be understood that in other embodiments, the box body 100 can also be fixedly connected to both the frame and the tank body.

[0085] It can be seen from the above technical solutions that the tank container 10 and the valve protection box 20 of the embodiment of the utility model have at least the following beneficial effects:

[0086] The valve protection box 20 of the embodiment of the present application, its box cover 200 is hinged to the box body 100 through the hinge component 300. Since the hinge component 300 includes two chain bodies 310 with the same structure, the standardized production of the hinge component 300 can be achieved, which greatly saves the production and processing costs. And the two chain bodies 310 are detachably connected to the box body 100 and the box cover 200, respectively, so as to facilitate the installation of the hinge component 300 with the box body 100 and the box cover 200, and the installation efficiency is high. Since the two chain bodies 310 are arranged symmetrically to each other, the box cover 200 will not be displaced after being opened and closed for many times, so that the hinged connection between the box cover 200 and the box body 100 is more reliable.

[0087] The valve protection box 20 of the present application has a simple structure, is easy to install and process, and has a good connection effect between the box cover 200 and the box body 100.

[0088] In addition, by providing the locking component 400 , the box cover 200 can be effectively prevented from being opened by mistake, thereby further improving the safety of the valve protection box 20 .

[0089] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

[0090] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive.
