Description

Technical Field

[0001] This utility model relates to the field of explosion-proof container technology, and more specifically, to a safe double-layer explosion-proof container. Background Technology

[0002] Explosion-proof storage and transportation tanks are important protective devices during the transfer of explosives to different locations. These devices can limit the blast radius of explosives within the tank, preventing and reducing harm to surrounding personnel and objects during an explosion. They can effectively suppress the lethal force of explosions. Therefore, these devices are suitable for use in security checks and bomb disposal at public security bureaus, airports, railway stations, customs, important locations, and large-scale events.

[0003] A search revealed that Chinese utility model patent application number CN202421926834.0 discloses a safe double-layer explosion-proof container, including a base, universal wheels fixedly installed below the base, an outer container fixedly installed above the base, the outer container being positioned in the middle of the base, an inner container inside the outer container, the bottom of the inner container being fixedly connected to the bottom of the outer container, the inner diameter of the inner container being smaller than the inner diameter of the outer container, a shock-absorbing rod fixedly installed on the inner wall of the outer container, a connector fixedly installed on the top of the shock-absorbing rod, the other end of the connector being fixedly connected to the inner container, and an explosion-proof cover being detachably installed on the top of the outer container.

[0004] Its threaded rod penetrates through the explosion-proof cover and is connected to the threaded hole screw. There is a gap between the threaded rod and the explosion-proof cover. Although there is a sealing thread connection between the sealing nut and the threaded rod, the sealing effect between the sealing nut and the explosion-proof cover is poor. It is not convenient to seal the explosion-proof cover on the inner and outer tanks. When disassembling the explosion-proof cover, the sealing nut needs to be rotated to the top, and then the explosion-proof cover needs to be rotated to the top. In order to put the explosive into the inner tank, the explosion-proof cover needs to be moved to a higher position. Therefore, a large number of rotations are required for the sealing nut and the explosion-proof cover. This operation is cumbersome and inconvenient to disassemble the explosion-proof cover. In addition, the shock-absorbing rod is arranged between the connector and the inner wall of the outer tank, which makes it inconvenient to disassemble the shock-absorbing rod. Utility Model Content

A rotating post is rotatably connected to the top seat. A screw is fixedly connected to the bottom of the rotating post. A threaded tube is threadedly connected to the outside of the screw. The threaded tube is fixedly connected to the top of the explosion-proof cover, which facilitates the sealing and pressing of the explosion-proof cover onto the outside of the inner and outer tanks, and also facilitates the disassembly of the explosion-proof cover.

[0009] The present invention is further provided that a first sealing gasket is fixedly connected to the bottom end of the explosion-proof cover to improve the sealing performance between the explosion-proof cover and the sealing cover.

[0010] The present invention is further provided that the explosion-proof cover is uniformly provided with multiple notches on its outer surface, and the multiple notches are respectively slidably engaged with multiple fixed posts to prevent the explosion-proof cover from rotating.

[0011] The present invention is further provided that a throttle is fixedly connected to the top end of the screw to facilitate the rotation of the screw.

[0012] The present invention is further configured such that a second sealing gasket is fixedly connected to the bottom end of the sealing cover, and the sealing cover is fixedly connected to the inner tank and the outer tank by a plurality of second screws. A countersunk groove is provided on the sealing cover at the position corresponding to the plurality of second screws to facilitate the fixing of the top ends of the inner tank and the outer tank.

[0014] The present invention is further configured such that multiple reinforcing ribs are uniformly fixedly connected to the outside of the outer tank, and the bottom ends of the multiple reinforcing ribs are fixedly connected to the base, thereby reinforcing the outer tank.

[0015] The present invention is further configured such that a limiting ring is fixedly connected to the rotating column below the top seat, which serves to limit the rotating column and prevent the rotating column from moving upward relative to the top seat.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a safe double-walled explosion-proof container, which has the following beneficial effects:

[0018] 1. Install multiple fixing posts on multiple fixing seats respectively, and then rotate the rotating post and the screw. The rotation of the screw causes the threaded tube to move relative to the screw. The threaded tube drives the explosion-proof cover to move downward, so that the explosion-proof cover is pressed tightly against the sealing cover. This avoids the screw and the explosion-proof cover being threadedly connected, which improves the sealing effect of the explosion-proof cover on the inner tank. Loosen multiple first screws to separate the locking post from the locking groove, and then the explosion-proof cover can be directly removed. Compared with the existing technology, it is easier to remove the explosion-proof cover and easier to put explosives into the interior of the inner tank.

[0030] Please see Figures 1-5A double-layered explosion-proof container includes a base 1, an outer container 2, and an inner container 3. The top of the base 1 is fixedly connected to the bottom of the outer container 2. The inner container 3 is fixedly installed inside the outer container 2. Multiple shock-absorbing components are detachably and evenly connected between the inner container 3 and the outer container 2. A sealing cover 4 is fixedly and sealed to the top of the inner container 3 and the outer container 2. The sealing cover 4 has an explosion-proof cover 5 at its top. A first sealing gasket 16 is fixedly connected to the bottom of the explosion-proof cover 5 to improve the sealing performance between the explosion-proof cover 5 and the sealing cover 4. Multiple fixing seats 6 are evenly arranged on the outside of the outer container 2. Each fixing seat 6 has a slot 7 at its top. A fixing post 8 is inserted into each slot 7. A slot 9 is provided on the side of each fixing post 8. A first screw 10 is threaded onto each fixing seat 6. The first screw 10 extends into the slot 7 and is fixedly connected to a locking post 11 that is compatible with the slot 9. The top of the multiple fixing posts 8 is fixedly connected to a top seat 12. A rotating post 13 is rotatably connected to the top seat 12. A limit ring 27 is fixedly connected to the rotating post 13 below the top seat 12 to limit the rotating post 13 and prevent it from moving upward relative to the top seat 12. A screw 14 is fixedly connected to the bottom of the rotating post 13. A threaded tube 15 is threadedly connected to the outside of the screw 14. The threaded tube 15 is fixedly connected to the top of the explosion-proof cover 5. A handle 18 is fixedly connected to the top of the screw 14 to facilitate the rotation of the screw 14. Multiple notches 17 are evenly provided on the outside of the explosion-proof cover 5. The multiple notches 17 slide with the multiple fixing posts 8 to prevent the explosion-proof cover 5 from rotating.

[0031] Specifically, multiple fixing posts 8 are installed on multiple fixing seats 6 respectively. Then, rotating the rotating post 13 and the screw 14 causes the threaded tube 15 to move relative to the screw 14. The threaded tube 15 drives the explosion-proof cover 5 to move downward, so that the explosion-proof cover 5 is sealed and pressed tightly on the sealing cover 4. This avoids the screw 14 from being threadedly connected to the explosion-proof cover 5, thus improving the sealing effect of the explosion-proof cover 5 on the inner tank 3. Loosening multiple first screws 10 separates the locking post 11 from the locking groove 9. Then, the explosion-proof cover 5 can be directly removed. Compared with the existing technology, it is easier to remove the explosion-proof cover 5 and easier to put explosives into the interior of the inner tank 3.

[0032] Please see Figure 1 and Figure 2 The bottom end of the sealing cover 4 is fixedly connected to a second sealing gasket 19. The sealing cover 4 is fixedly connected to the inner tank 3 and the outer tank 2 by multiple second screws 20. The sealing cover 4 is provided with countersunk grooves 21 at the positions corresponding to the multiple second screws 20, which facilitates the fixing of the top ends of the inner tank 3 and the outer tank 2. Multiple reinforcing ribs 26 are evenly fixedly connected to the outside of the outer tank 2. The bottom ends of the multiple reinforcing ribs 26 are all fixedly connected to the base 1, which plays a role in reinforcing the outer tank 2.

[0033] Specifically, the sealing cap 4 is fixedly connected to the inner tank 3 and the outer tank 2 by multiple second screws 20. The sealing cap 4 seals the gap between the inner tank 3 and the outer tank 2, and at the same time, it fixes the top of the inner tank 3 and the outer tank 2 to prevent deformation of the top of the inner tank 3 and the outer tank 2. Multiple reinforcing ribs 26 are fixedly connected to the outside of the outer tank 2 to improve the strength of the outer tank 2 and enhance its explosion-proof effect.

[0034] Please see Figure 3 The shock absorber includes two mounting seats 22. Multiple first U-shaped seats 23 are evenly fixedly connected to the inner side wall of the outer tank 2, and multiple second U-shaped seats 24 are evenly fixedly connected to the outer side wall of the inner tank 3. A shock-absorbing rubber pad 25 is fixedly connected between the two mounting seats 22. The two mounting seats 22 are respectively inserted into the corresponding first U-shaped seats 23 and second U-shaped seats 24 to support the outer side wall of the inner tank 3 and improve the explosion-proof effect of the inner tank 3.

[0035] Specifically, the two mounting bases 22 and the shock-absorbing rubber pads 25 are installed between the inner tank 3 and the outer tank 2 by inserting them into the corresponding first U-shaped base 23 and second U-shaped base 24. The two mounting bases 22 and the shock-absorbing rubber pads 25 support the inner tank 3, improve the explosion-proof effect of the inner tank 3, and facilitate the disassembly and replacement of the two mounting bases 22 and the shock-absorbing rubber pads 25.

[0036] In summary, when using the overall equipment:

[0037] The explosive is placed inside the inner container 3, and then the explosion-proof cover 5 is placed on the sealing cover 4. Multiple fixing posts 8 are inserted into multiple slots 7 respectively. Then, the first screw 10 is turned clockwise. The first screw 10 drives the locking post 11 to move and insert the locking post 11 into the slot 9, fixing the fixing post 8 inside the fixing base 6. Then, the handle 18, the rotating post 13 and the screw 14 are turned counterclockwise. The screw 14 rotates and causes the threaded tube 15 to move downward relative to the screw 14. The threaded tube 15 drives the explosion-proof cover 5 to move downward, so that the explosion-proof cover 5 is pressed against the sealing cover 4, sealing the inner container 3 through the explosion-proof cover 5. Then, the explosive is transferred by rolling on the ground through the universal wheels on the base 1.
