[0002] The smoke bomb firing box, as a part of the projectile smoke screen device, usually works together with the launch tube, smoke bomb, launch bracket and other components to achieve the generation and dispersion of smoke screen. Modern smoke screen devices mostly use electric firing, that is, the mechanical or electronic device in the firing box is triggered by an electrical signal, which then ignites the propellant of the smoke bomb and causes the smoke bomb to be fired from the launch tube at high speed.

[0003] The smoke bomb firing box needs to be properly kept when in use to prevent accidental triggering during carrying or storage. The firing method of the conventional smoke bomb firing box is relatively simple, and it does not have a component to prevent accidental triggering, so further improvement can be made.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-Figure 4 As shown, a smoke bomb firing box anti-misfire device comprises a storage box 1 and a box cover 2, the box cover 2 is hinged at the top rear side of the storage box 1, a firing box body 3 is fixedly installed on the bottom wall of the storage box 1, two groups of cross bars 4 are fixedly installed between the front and rear side walls of the storage box 1, the tops of the two groups of cross bars 4 are attached with plastic films 5, the horizontal part of the plastic film 5 is located just above the firing box body 3, and two ends of the plastic film 5 are respectively fixedly installed with vertical rods 6, the two groups of vertical rods 6 are respectively located on the left and right sides of the firing box body 3, and the front and rear sides of the two groups of vertical rods 6 are provided with counterweight components 7, and the counterweight components 7 are used to drive the vertical rods 6 to move downward and tighten the plastic film 5. The cross bar 4 is higher than the top of the firing box body 3, and the weight of the counterweight component 7 makes the two groups of vertical rods 6 have a tendency to move downward, thereby tightening the plastic film 5 and making the plastic film 5 arched. And due to the weight of the counterweight component 7, when pressing the plastic film 5 downward, a large force is required, thereby preventing the firing box body 3 from being accidentally triggered.

[0019] When in use, the counterweight assembly 7 includes two enclosure covers 701 fixedly mounted on the front and rear side walls of the storage box 1, and a receiving cavity is formed between the enclosure covers 701 and the storage box 1. A slot 702 is provided through the top of the enclosure cover 701, and a slide groove 703 is provided through the left and right sides of the enclosure cover 701. A connecting plate 704 is slidably connected in the slide groove 703. Two groups of decorative covers 705 are fixedly mounted on the surface of the connecting plate 704. The two groups of decorative covers 705 are respectively attached to the left and right side walls of the enclosure cover 701 and cover the opening of the slide groove 703. The two ends of the connecting plate 704 are respectively fixedly mounted on the ends of the two groups of vertical rods 6. A counterweight block 706 is fixedly mounted on the top of the connecting plate 704, and the counterweight block 706 is inserted in the slot 702. The counterweight block 706 is made of metal, such as steel. The weight of the counterweight 706 causes the connection plate 704 and the decorative cover 705 to move downward, thereby driving the vertical rod 6 to move downward, tightening the plastic film 5. When the plastic film 5 is tightened, the top of the counterweight 706 is flush with the top of the enclosure cover 701. When the plastic film 5 is pressed downward, the middle of the plastic film 5 is sunken downward, causing the two groups of vertical rods 6 to move upward; correspondingly, the connection plate 704 slides inside the slide groove 703, and during the sliding process of the connection plate 704, the decorative cover 705 always keeps the slide groove 703 sealed.

[0020] In practice, a sealing plate 8 is fixedly installed on the top of the storage box 1. The sealing plate 8 cooperates with the enclosure cover 701 to seal the opening of the storage box 1. The sealing plate 8 is attached to the top of the plastic film 5. A through hole 9 is provided at the center of the sealing plate 8. The through hole 9 is sealed by the plastic film 5. The sealing plate 8 cooperates with the enclosure cover 701 to seal the opening of the storage box 1. In addition, during the sliding process of the connecting plate 704, the decorative cover 705 always seals the slide groove 703 to prevent dust from falling on the firing box body 3. In addition, the plastic film 5 is made of transparent plastic material, and the writing on the surface of the firing box body 3 can be observed through the plastic film 5, and the writing on the top of the firing box body 3 can be prevented from being blurred due to long-term use.

[0021] Specifically, a blocking member is provided on the top of the sealing plate 8, and the blocking member is attached to the top of the counterweight 706. The blocking member includes two sets of fixed shafts 10 fixedly installed on the top of the sealing plate 8, and a blocking piece 11 is rotatably connected to the outer side of the fixed shaft 10, and one end of the blocking piece 11 is V-shaped and the other end is arc-shaped. The V-shaped end of the blocking piece 11 is attached to the top of the counterweight 706, and a fixing piece 13 is fixedly installed on the top of the fixed shaft 10, and the fixing piece 13 is attached to the top of the blocking piece 11. The blocking piece 11 blocks the top of the counterweight 706, preventing the counterweight 706 from moving upward, thereby inhibiting the vertical rod 6 from moving upward. The resistance when the plastic film 5 is pressed downward is enhanced, and the firing box body 3 is further prevented from being triggered by mistake.

[0022] In reality, a V-shaped groove 12 is arranged on the arc-shaped end of the blocking piece 11, a U-shaped plate 14 is fixedly installed between the other end of the fixing piece 13 and the sealing plate 8, a clamping block 15 is slidably connected in the U-shaped plate 14, a spring 16 is fixedly installed between the clamping block 15 and the inner wall of the U-shaped plate 14, and under the elastic action of the spring 16, the clamping block 15 abuts against the V-shaped groove 12. The blocking piece 11 is limited to rotate by the clamping block 15, and after the blocking piece 11 is rotated, the blocking piece 11 is kept in the current position. The blocking piece 11 stably blocks the counterweight 706, and further prevents the firing box body 3 from being triggered by mistake.
