Description

Technical Field

[0001] This invention relates to the field of tank container technology, and particularly to an overflow box for a tank container. Background Technology

[0002] Traditional tank containers (hereinafter referred to as tank containers) are generally equipped with an overflow box and an overflow box cover on the top to protect the top valves. Currently, the overflow box and cover are usually locked with pins. When tank container operators need to load, unload, clean, or perform other operations, they need to climb onto the top of the tank container to manually operate the overflow box.

[0003] However, due to the limitations of its structure, the existing latch requires the following steps to operate the overflow box: first, manually pull open the latch, then lift the lid, then flip the lid over, and finally fully open the lid. To close the overflow box, first manually rotate the lid, then close it, then insert the latch, and finally lock the latch to close the overflow box. All of these operations require manual operation and are complex and cumbersome. Furthermore, since the operation is performed by workers, there is a possibility that the latch may be forgotten to be locked after closing the lid, leading to the overflow box being opened during transportation and even damage to the valve components. Summary of the Invention

[0004] The purpose of this invention is to provide an overflow box for a tank container, which solves the technical problem of controlling the loosening or locking of the latch while opening or closing the overflow box cover, thereby simplifying the opening or closing of the overflow box.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An overflow box for a tank container includes: a box body disposed on the tank; a box cover having a first side and a second side opposite to each other; the first side of the box cover is hinged to the box body, and the box cover has a pin hole; a pin assembly including a transmission member, a pin disposed on one side of the transmission member, and a drive unit for moving the transmission member; the pin is connected to the transmission member and can move with the transmission member to be inserted into or disengaged from the pin hole; the drive unit is fixed to the box body; and a linkage assembly disposed between the box cover and the transmission member and cooperating with the transmission member; when the transmission member drives the pin to disengage from the pin hole, the transmission member drives the box cover to open via the linkage assembly; when the transmission member drives the pin to insert into the pin hole, the transmission member drives the box cover to close via the linkage assembly.

[0007] In one embodiment of this application, the transmission member is capable of sliding in a straight line relative to the box body; the transmission member has a transmission part and an unloaded part connected in the sliding direction; when the transmission member drives the pin from the insertion position to the disengagement position, the engagement between the transmission member and the linkage component moves from the unloaded part to the transmission part, so that the transmission member can drive the linkage component to open the box lid as it continues to move forward; when the transmission member drives the pin from the disengagement position to the insertion position, the engagement between the transmission member and the linkage component moves from the transmission part to the unloaded part, so that the transmission member can drive the linkage component to close the box lid as it moves.

[0008] In one embodiment of this application, the box body is provided with a slide rail; the slide rail is located on the side where the box body and the box cover are hinged; the transmission component is slidably connected to the slide rail.

[0009] In one embodiment of this application, the linkage component includes an inertial gear and a driven gear; the transmission part is provided with a transmission rack; the driven gear is fixed on the box cover; the inertial gear is rotatably disposed on the box body and meshes between the driven gear and the transmission rack.

[0010] In one embodiment of this application, the pin assembly further includes a connecting rod; one end of the connecting rod is fixed to the transmission member, and the other end is provided with a mounting portion; the pin is slidably connected to the connecting plate through the mounting portion.

[0011] In one embodiment of this application, the mounting portion is a mounting hole; the pin is provided with a first shaft portion and a second shaft portion; the first shaft portion is clearance-fitted with the mounting hole, and the second shaft portion is interference-fitted with the mounting hole, so that the pin and the mounting portion can be detachably connected by adjusting the fit between the first shaft portion and the second shaft portion and the mounting hole.

[0012] In one embodiment of this application, the pin is further provided with a handle, so as to manually adjust the connection between the pin and the mounting part through the handle, and drive the pin to insert into or disengage from the pin hole.

[0013] In one embodiment of this application, the housing is provided with a snap-fit ​​part, which is used to snap the handle part to fix the pin.

[0014] In one embodiment of this application, the pin assembly further includes a pin slide sleeve, the pin slide sleeve being fixed to the housing, and the pin being slidably disposed within the pin slide sleeve.

[0015] In one embodiment of this application, the pin assembly further includes a guide member, which is fixed to the housing, and the connecting rod is slidably disposed on the guide member to guide the connecting rod to translate.

[0016] As can be seen from the above technical solution, the present invention has at least the following advantages and positive effects:

[0017] In this invention, the overflow box body is mounted on the tank body, and the lid is hinged to the body, with a pin hole on the lid. Simultaneously, in the pin assembly of the overflow box, a transmission component engages with the lid via a linkage component, enabling the transmission component to rotate the lid. Furthermore, one end of the transmission component is connected to a pin that engages with the pin hole, so that when the drive unit moves the transmission component, the transmission component can cause the pin to disengage from or insert into the pin hole. Therefore, during the process of the transmission component disengaging the pin from the pin hole, the transmission component opens the lid via the linkage component; during the process of the transmission component inserting the pin into the pin hole, the transmission component closes and locks the lid via the linkage component, thereby simplifying the opening and closing of the overflow box.

These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] The solution is further illustrated by the following examples:

[0030] Please see Figure 1 The overflow box of the tank container in this embodiment includes a box body 10, a box cover 20, a latch assembly 30, and a linkage assembly 40.

[0031] The container body 10 is mounted on the can body 1, and the lid 20 is hinged to the container body 10 so that it can be flipped relative to the container body 10 to open or close. A latch assembly 30 is used to lock the lid 20 onto the container body 10 to prevent the lid 20 from rotating relative to the container body 10. A linkage assembly 40 is used to cause the lid 20 to flip when the latch assembly 30 is moved, thereby opening or closing the lid 20.

[0032] See Figure 1 The box body 10 is provided with a slide rail 11, which is located on the side where the box body 10 is hinged to the box cover 20. In this embodiment, the slide rail 11 is located below the linkage component 40 and is used to slide the pin component 30 so that the pin component 30 can slide relative to the box body 10.

[0033] See Figure 1 , Figure 2 The lid 20 has a first side 21 and a second side 22, with the first side 21 hinged to the box body 10. A pin hole 23 is provided on the lid 20. In this embodiment, the pin hole 23 is located near the second side 22 of the lid 20, so that after the pin assembly 30 is inserted into the pin hole 23, the lid 20 can be more securely locked to the box body 10. It should be noted that in this embodiment, the pin hole 23 is provided on a plate, and the plate is welded to the lid 20. In some other embodiments, the pin hole 23 may also be located between the first side 21 and the second side 22, or it may be located on the side closer to the second side 22, so that the lid 20 can be locked to the box body 10.

[0034] It should be noted that, in this embodiment, the lid 20 also includes a lid handle 24 disposed on the second side 22 to facilitate manual opening of the lid 20.

[0035] Furthermore, the latch assembly 30 includes a transmission member 31, a latch 32, and a drive unit 33. The transmission member 31 is slidably connected to the slide rail 11, allowing it to slide linearly relative to the housing 10. The latch 32 is located on one side of the transmission member 31 and connected to it, enabling it to move with the transmission member 31. The latch 32 is used to insert into or disengage from the pin hole 23 to lock or release the housing cover 20. That is, when the latch 32 is inserted into the pin hole 23, it locks the housing cover 20 onto the housing 10, preventing it from opening automatically; when the latch 32 disengages from the pin hole 23, it releases the housing cover 20 from the housing 10. The drive unit 33 is fixed to the housing 10 and drives the transmission member 31 to move it.

[0036] It should be noted that the drive unit 33 can be configured as a cylinder, motor or other components, so as to drive the transmission component 31 to move under the drive of the cylinder or motor.

[0037] In this embodiment, the transmission member 31 has a transmission part 311 and an unloaded part 312 connected in the sliding direction. The linkage assembly 40 is disposed between the lid 20 and the transmission member 31 and cooperates with the transmission member 31 to drive the lid 20 to flip.

[0038] That is, during the process of the transmission member 31 driving the pin 32 from the insertion position to the disengagement position, the engagement between the transmission member 31 and the linkage assembly 40 moves from the unloaded part 312 to the transmission part 311, such as... Figure 3 As shown, when the unloaded portion 312 of the transmission component 31 engages with the linkage assembly 40, the linkage assembly 40 does not rotate; after the pin 32 disengages from the pin hole 23, as the transmission component 31 continues to move forward, the transmission portion 311 of the transmission component 31 engages with the linkage assembly 40, thereby driving the linkage assembly 40 to rotate and opening the cover 20, as shown. Figure 4 As shown, at this time, the transmission part 311 and the linkage assembly 40 continuously cooperate. When the transmission member 31 drives the pin 32 from the disengaged position to the inserted position, the transmission part 311 of the transmission member 31 first cooperates with the linkage assembly 40, thereby driving the cover 20 to close. After the cover 20 is closed, as the transmission member 31 continues to move forward, the cooperation between the transmission member 31 and the linkage assembly 40 moves from the transmission part 311 to the unloaded part 312, so that the transmission member 31 can continue to drive the pin 32 forward, thereby inserting the pin 32 into the pin hole 23, as shown. Figure 5 As shown.

[0039] See Figure 1 and Figure 6 The pin assembly 30 also includes a connecting rod 34. One end of the connecting rod 34 is fixed to the transmission member 31, and the other end is provided with a mounting part 341. The pin 32 is slidably connected to the connecting plate through the mounting part 341.

[0040] It should be noted that, in this embodiment, the connecting rod 34 is further provided with a connecting plate 342, and the mounting part 341 is disposed on the connecting plate 342, and the connecting plate 342 is disposed on the end of the connecting rod 34. In this embodiment, the mounting part 341 is a mounting hole.

[0041] like Figure 6 As shown, the pin 32 is provided with a first shaft portion 321 and a second shaft portion 322. The first shaft portion 321 is clearance-fitted with the mounting hole, and the second shaft portion 322 is interference-fitted with the mounting hole. By adjusting the fit between the first shaft portion 321 and the second shaft portion 322 and the mounting hole, a detachable connection between the pin 32 and the mounting part 341 can be achieved. That is, when the first shaft portion 321 is fitted with the mounting hole, the first shaft portion 321 is clearance-fitted with the mounting hole, so the pin 32 can move relative to the connecting rod 34. This allows the pin 32 to be operated manually, so that the pin 32 can be inserted into or disengaged from the pin hole 23, thereby manually opening or closing the cover 20. When the second shaft portion 322 is fitted with the mounting hole, the second shaft portion 322 is interference-fitted with the mounting hole, so the pin 32 is fixed on the connecting rod 34 and can move with the connecting rod 34. Thus, driven by the transmission member 31, it can be inserted into or disengaged from the pin hole 23.

[0042] See Figure 6 The pin 32 is also provided with a handle 323, which allows manual adjustment of the connection between the pin 32 and the mounting part 341, and to drive the pin 32 into or out of the pin hole 23. That is, by manually moving the pin 32 with the handle 323, the connection between the first shaft part 321 or the second shaft part 322 of the pin 32 and the mounting part 341 is adjusted, that is, the fit between the first shaft part 321 or the second shaft part 322 and the mounting hole is adjusted, thereby facilitating the disengagement of the pin 32 from the connecting rod 34 or its fixing together.

[0043] In addition, the housing 10 is provided with a snap-fit ​​part 12, which is used to snap the handle part 323 to fix the pin 32 and prevent the pin 32 from shaking when it is manually operated, thereby affecting the work.

[0044] See Figure 6 The pin assembly 30 also includes a pin sleeve 35, which is fixed to the housing 10, and the pin 32 is slidably disposed within the pin sleeve 35. In this embodiment, the pin sleeve 35 is used to limit the degree of freedom of the pin 32 so that the pin 32 can only move in the same direction.

[0045] In addition, the pin assembly 30 also includes a guide 36, which is fixed to the housing 10. The connecting rod 34 is slidably disposed on the guide 36 to guide the translation of the connecting rod 34. In this embodiment, the guide 36 can guide and limit the pin 32, so that the pin 32 can move in the same direction.

[0046] See Figure 1 The linkage component 40 includes an idler gear 41 and a driven gear 42. It should be noted that in this embodiment, the transmission part 311 is provided with a transmission rack that meshes with the idler gear 41, so that the idler gear 41 transmits power to the transmission component 31 via the transmission rack. The unloaded part 312 is a straight section that does not mesh with the idler gear 41; that is, the unloaded part 312 is redundant, so that when the idler gear 41 is on the unloaded part 312, the idler gear 41 does not transmit power to the transmission component 31. In this embodiment, the driven gear 42 is fixed to the lid 20, and the idler gear 41 is rotatably mounted on the box body 10, meshing between the driven gear 42 and the transmission rack, so that the transmission rack can drive the idler gear 41 to rotate, and the idler gear 41 can drive the driven gear 42 and the lid 20 to rotate, thereby opening or closing the lid 20.

[0047] It should be noted that in some other embodiments, the linkage component 40 can also be configured as a roller driven by friction. In this solution, the transmission part 311 is provided with a friction part. Through the frictional engagement between the roller and the transmission part 311, the linkage component 40 and the lid 20 are driven to rotate, thereby opening the lid 20. At the same time, in this solution, the unloaded part 312 is configured as a smooth part that cannot engage with the roller by friction, thereby avoiding transmission between the roller and the unloaded part 312.

[0048] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
