Description

Technical Field

[0001] The utility model relates to the technical field of tank containers, in particular to a novel bottom discharge protection box and a tank container with the same. Background Art

[0002] A tank container is an ideal transportation container for loading and transporting a large amount of liquid or gas. Usually, in most cases, it is used to load toxic, harmful, flammable or corrosive liquids, which is extremely dangerous.

[0003] The tank container is provided with a bottom discharge port, and a valve member is installed at the bottom discharge port. Generally, a bottom discharge protection box needs to be installed around the bottom discharge port to protect the valve member. After the box cover is opened, it will fall due to gravity, which causes inconvenience in operation. The prior art, such as the Chinese utility model patent CN203094857U, discloses an operation box of a tank container, which uses a combination of a box door positioning member and an elastic positioning member to keep the box cover in an open state. However, the above technical solutions have the following disadvantages: 1) The elastic positioning member and the box door positioning member are pressed against each other. As the number of openings and closings increases, the elastic positioning member and the box door positioning member are severely worn. When any one of them is damaged, it is easy to get stuck when opening the box door; 2) In actual application of the box door positioning member, a certain angle needs to be formed between the positioning plate and the box door, which is relatively cumbersome to manufacture; 3) The elastic positioning member generally uses a spring to achieve reset. The spring is prone to failure when repeatedly opening and closing the box door. If the spring fails, the spring needs to be replaced, and the maintenance is inconvenient. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the Invention

Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0035] Please refer to Figures 1-6 , a new type of bottom discharge protection box provided by an embodiment of the present utility model includes a bottom box 1, a box cover 2, a main hinge assembly 3, and a stop member 4 slidably disposed on the box cover 2. The hinged end of the bottom box 1 is hinged to the hinged end of the box cover 2 through the main hinge assembly 3. The main hinge assembly 3 or the bottom box 1 defines a limit hole 3011. When the box cover 2 is in the open position, the stop member 4 is inserted into the limit hole 3011 to limit the rotation of the box cover 2. During the opening process of the box cover 2, the stop member 4 moves with the box cover 2. When the box cover 2 is opened, the stop member 4 will slide into the limit hole 3011 to limit the rotation of the box cover 2. In this way, the box cover 2 will not close due to gravity. The structure is simple and practical, with small wear, long service life, and convenient maintenance operation.

[0036] When the bottom box 1 defines the limit hole 3011, the stop member 4 passes through the hinged end of the box cover 2 and is inserted into the limit hole 3011. When the main hinge assembly 3 defines the limit hole 3011, the stop member 4 passes through the hinged end of the box cover 2 and is inserted into the limit hole 3011 on the main hinge assembly 3 to limit the rotation of the box cover 2 after it is opened.

[0037] Such as Figure 1 ,Figure 2 and Figure 5 As shown in Figure 5 , the main hinge assembly 3 includes a hinge bracket 301 fixedly arranged at the hinge end of the bottom box 1, and two symmetrically arranged main hinge ear plates 302 fixedly arranged at the hinge end of the lid 2. The hinge bracket 301 is located between the two main hinge ear plates 302. The hinge bracket 301 and the main hinge ear plates 302 are rotationally connected by bolts or pins. The hinge bracket 301 is provided with a limit hole 3011. A relief hole 201 is provided through the hinge end of the lid 2. The relief hole 201 corresponds to the limit hole 3011. The structure of the main hinge assembly 3 is simple, easy to install and disassemble. The limit hole 3011 is opened on the hinge bracket 301. The stopper 4 passes through the relief hole 201 and is inserted into the limit hole 3011, which has a good effect of restricting the rotation of the lid 2.

[0038] As Figure 1 and Figure 4 As shown in Figure 1 and Figure 4 , the stopper 4 includes a stop portion 401 and a limit portion 402 arranged at one end of the stop portion 401. The limit portion 402 and the stop portion 401 are integrally connected to form an L-shaped structure. When the lid 2 is in the open position, the stop portion 401 is inserted into the limit hole 3011. The stopper 4 can slide as the lid 2 is opened and enter the limit hole 3011 to restrict the rotation of the lid 2. The staff can also manually push the stopper 4 into the limit hole 3011. When the lid 2 needs to be closed, the staff pulls out the stopper 4 and then closes the lid 2. The structure is simple and practical.

[0039] Furthermore, as Figure 1 and Figure 2 As shown in Figure 1 and Figure 2 , a support seat 5 is fixedly arranged on the inner surface of the lid 2. The stopper 4 is slidably inserted into the support seat 5. The support seat 5 has a U-shaped groove 501. The stop portion 401 slides in the U-shaped groove 501. When the lid 2 is opened, the limit portion 402 cooperates with the support seat 5 to prevent the stopper 4 from falling off the lid 2.

[0040] As Figure 1 and Figure 2 As shown in Figure 1 and Figure 2 , a limit plate 6 is arranged above the stopper 4. The limit plate 6 is perpendicular to the lid 2 and fixedly connected to the lid 2. When the lid 2 is closed, the limit plate 6 cooperates with the limit portion 402 to prevent the stopper 4 from falling off the lid 2 when the lid 2 is closed.

[0041] As Figure 3 and Figure 4As shown in the figure, the straight-line distance from the side of the limiting plate 6 facing the avoidance hole 201 to the avoidance hole 201 is h. In the fully opened state of the box cover 2, the straight-line distance from the side of the limiting plate 6 facing the avoidance hole 201 to the limiting hole 3011 is H, and the length of the stopper 4 is L, where h ≤ L ≤ H. If the stopper 4 is less than h, it is likely to fall off during the opening and closing process of the box cover 2. If the stopper 4 is greater than H, when opening the box cover 2, one end of the stopper 4 will abut against the bottom box 1, resulting in limited opening of the box cover 2.

The secondary hinge assembly 7 includes a hinge plate 701 fixedly provided at the hinged end of the bottom box 1 and a secondary hinge ear plate 702 fixedly provided at the hinged end of the box cover 2. The hinge plate 701 and the secondary hinge ear plate 702 are rotatably connected. The cooperation of the secondary hinge assembly 7 and the main hinge assembly 3 makes the opening and closing of the box cover 2 more stable, and the connection between the box cover 2 and the bottom box 1 is also more firm.

[0043] As Figure 1 and Figure 2 shown, one elastic locking assembly 8 is provided on each side of the bottom box 1, and one locking plate 9 is provided on each side of the box cover 2. A locking hole 901 is provided through the locking plate 9. When the box cover 2 is in the closed position, the elastic locking assembly 8 is inserted into the locking hole 901, which is convenient to operate and has a good locking effect.

[0044] As Figure 1 and Figure 2 shown, the elastic locking assembly 8 includes a support 801, a locking rod 802 detachably inserted into the support 801, and a spring 803 sleeved on the locking rod 802. The locking rod 802 is of an L-shaped structure, which is convenient for the staff to continue the operation. A pressure rod 804 is vertically inserted into the locking rod 802. One end of the spring 803 abuts against the pressure rod 804, and the other end abuts against the support 801. The cooperation of the secondary hinge assembly 7 and the main hinge assembly 3 makes the opening and closing of the box cover 2 more stable. Further, an installation hole 8021 is provided at one end of the locking rod 802 to penetrate it radially, and a pin is provided in the installation hole 8021 for locking.

[0045] Please refer to Figures 1-6, the present utility model further provides a tank container, including a tank body 10, a frame, and a protection box.
