Description

Technical Field

[0001] This utility model relates to the field of fireworks, namely, fireworks devices for entertainment, display, lighting or signaling, and in particular to a safety testing device for fireworks leaving the factory. Background Technology

[0002] Fireworks factory safety testing devices are specialized equipment or systems used to test the safety performance of fireworks after production and before they leave the factory. These devices ensure the safety of fireworks products during storage, transportation, and use through a series of tests, reducing the occurrence of accidents such as fires and explosions. Existing fireworks factory safety testing devices mostly use a motor-driven moving plate to raise the fireworks and detect leaks. However, this method only detects leaks in one direction, making it inconvenient to detect leaks in other areas. This can easily lead to leaks in other areas, potentially causing explosions during transportation. Therefore, a new fireworks factory safety testing device is needed to solve these problems. Utility Model Content

[0003] The purpose of this invention is to solve the problem that existing technologies can only detect whether there is a leak in one direction of fireworks, and thus propose a safety detection device for fireworks leaving the factory.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a safety testing device for fireworks leaving the factory, comprising a base plate, with support plates vertically fixed on both sides of the top of the base plate, and a connecting rod fixedly connected between the top centers of the two support plates, and a fixing plate longitudinally fixed at the top center of the base plate, a motor fixedly installed at the top outer end of one of the support plates, and a bidirectional screw fixedly connected laterally at the output end of the motor, and the bidirectional screw rotatably installed between the tops of the two support plates, with threaded blocks threaded at both ends of the bidirectional screw, and the threaded blocks located at the bottom of the connecting rod.

[0005] Furthermore, each of the two threaded blocks has an electric telescopic rod fixedly installed vertically at its bottom, and each of the two electric telescopic rods has a pull ring fixedly installed at its bottom. Each of the two support plates has a groove vertically opened at its center end face, and each of the two grooves has a movable block slidably installed in its groove. Each of the two movable blocks has a slider fixedly installed at both ends, and each of the two grooves has a sliding groove, with the slider slidably installed in the sliding groove.

[0006] Furthermore, a rotating rod is rotatably mounted at the center of each of the two moving blocks. Limiting plates are fixedly mounted on the surfaces of both ends of the rotating rod, and the two limiting plates are located on both sides of the moving block. A rectangular rod is fixedly mounted at the inner end of each of the two rotating rods, and the two rectangular rods are located between the two support plates.

[0007] Furthermore, rectangular tubes are slidably fitted onto the surfaces of both rectangular rods, and concave rings are fixedly installed on the outer end surfaces of both rectangular tubes. Two pull rings are respectively fitted into the center of the two concave rings. A cross is fixedly installed at one end of each of the two concave rings, and a locking plate is horizontally fixed at each of the four ends of the two crosses. The two sets of crosses and locking plates are set correspondingly.

[0008] Furthermore, gears are fixedly installed at the outer ends of both rotating rods, and the gears are located outside the support plates. Racks are vertically fixed on both sides of the outer ends of the two support plates, and the gears are meshed between the two racks.

[0009] The beneficial effects of this utility model are as follows: By driving the two crosses to move closer together, the two sets of clamping plates clamp the fireworks. Then, the two electric telescopic rods are activated to retract, which facilitates the upward movement of the two pull rings. The two concave rings then pull the two rectangular cylinders upward, which in turn drive the two rotating rods upward. This facilitates the upward movement of the two moving blocks within the two grooves. The upward movement of the two rotating rods facilitates the upward movement of the two gears. The upward movement of the two gears between the two sets of racks facilitates their rotation, thereby facilitating the rotation of the fireworks between the two crosses. This allows the fireworks to rotate simultaneously while being lifted, making it easier to detect leaks from all directions and effectively preventing leaks from other parts of the fireworks, thus effectively preventing explosions during transportation.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1 to 6 This embodiment provides a safety testing device for fireworks leaving the factory, including a base plate 1. Support plates 2 are vertically fixed on both sides of the top of the base plate 1, and a connecting rod 3 is fixedly connected between the top centers of the two support plates 2. A fixing plate 4 is longitudinally fixed at the top center of the base plate 1. A motor 5 is fixedly mounted on the outer top end of one of the support plates 2. A bidirectional screw 6 is horizontally fixedly connected to the output end of the motor 5, and the bidirectional screw 6 is rotatably mounted between the tops of the two support plates 2. Threaded blocks 7 are threaded onto both ends of the bidirectional screw 6, and the threaded blocks 7 are located at the bottom of the connecting rod 3. Preferably, by setting... The base plate 1 facilitates the fixed installation of the safety detection device on the ground. The support plate 2 facilitates the installation of the connecting rod 3 above the base plate 1, and the connecting rod 3 facilitates the connection of the two support plates 2. The fixing plate 4 facilitates the placement of fireworks on the base plate 1, which makes it convenient to clamp the fireworks on the base plate 1 later. The motor 5 facilitates the rotation of the bidirectional screw 6 between the tops of the two support plates 2. The rotation of the bidirectional screw 6 facilitates the movement of the two threaded blocks 7 closer or further away at the bottom of the connecting rod 3, which is convenient for the motor 5 to drive the two threaded blocks 7 to move closer or further away.

[0019] Furthermore, each of the two threaded blocks 7 has an electric telescopic rod 8 vertically fixed at its bottom, and each of the two electric telescopic rods 8 has a pull ring 9 fixedly fixed at its bottom. The center end faces of both support plates 2 have vertically formed grooves 10, and each of the two grooves 10 has a sliding block 11 slidably mounted therein. Each of the two sliding blocks 11 has a slider fixedly mounted at both ends, and each of the two grooves 10 has a sliding groove, with the slider slidably mounted within the groove. Preferably, the threaded blocks 7 facilitate the fixed mounting of the electric telescopic rods 8 at their bottoms, and the electric telescopic rods 8 facilitate the up-and-down movement of the two pull rings 9. The movement of the two threaded blocks 7 towards or away facilitates the movement of the two electric telescopic rods 8 towards or away, thereby facilitating the movement of the two pull rings 9 towards or away. The grooves 10 facilitate the vertical sliding of the moving blocks 11 within the center end faces of the two support plates 2. The moving blocks 11 also facilitate the vertical opening of the grooves 10 on the center end faces of the support plates 2. The sliding grooves and sliders facilitate the up-and-down movement of the moving blocks 11 within the grooves 10, thereby preventing the moving blocks 11 from dislodging from the grooves 10 and enhancing the stability of the moving blocks 11's up-and-down movement within the grooves 10.

[0020] Furthermore, a rotating rod 12 is laterally rotatably mounted at the center of each of the two moving blocks 11. Limiting plates 13 are fixedly mounted on the surfaces of both ends of the rotating rod 12, with the two limiting plates 13 located on opposite sides of the moving block 11. A rectangular rod 14 is laterally fixed at the inner end of each of the two rotating rods 12, and the two rectangular rods 14 are located between the two support plates 2. Preferably, the moving blocks 11 facilitate the lateral rotation of the rotating rod 12 at their center, the rectangular rods 14 facilitate rotation and vertical movement between the two support plates 2, and the rotating rods 12 facilitate the placement of limiting plates 13 on both sides of the moving block 11. The limiting plates 13 effectively limit the position of the rotating rod 12 within the moving block 11, preventing left and right movement of the rotating rod 12 within the moving block 11 and thus enhancing the stability of the rotating rod 12 within the moving block 11.

[0021] Furthermore, rectangular tubes 15 are slidably fitted onto the surfaces of both rectangular rods 14. Concave rings 16 are fixedly mounted on the outer surfaces of both rectangular tubes 15. Two pull rings 9 are respectively fitted into the centers of the two concave rings 16. A cross 17 is fixedly mounted on one end of each of the two concave rings 16. A retaining plate 18 is horizontally fixed at each of the four ends of each cross 17, and the two sets of crosses 17 and retaining plates 18 are correspondingly arranged. Preferably, the rectangular rods 14 facilitate the rotation of the rotating rod 12, which in turn drives the rectangular tubes 15 to rotate. The rectangular tube 15 facilitates the rotation of the rectangular rod 14, which in turn drives the concave ring 16 to rotate. The concave ring 16 facilitates the mounting of the pull ring 9 on the rectangular tube 15, allowing the rectangular tube 15 to move up and down and left and right. The cross 17 facilitates the limiting of the fireworks on the base plate 1 and the fixed plate 4. The clamping plate 18 facilitates the clamping of the fireworks between the two crosses 17, thereby facilitating the driving of the two rectangular tubes 15 to move closer together and clamp the fireworks onto the base plate 1.

[0022] Furthermore, gears 19 are fixedly installed at the outer ends of both rotating rods 12, and the gears 19 are located outside the support plate 2. Racks 20 are vertically fixed on both sides of the outer ends of the two support plates 2, and the gears 19 are meshed between the two racks 20. Preferably, the rotating rods 12 facilitate the installation of gears 19 outside the support plate 2, the gears 19 facilitate the rotation of the rotating rods 12 within the moving block 11, and the racks 20 facilitate the rotation of the up-and-down moving gears 19, thereby facilitating the upward and rotation of the fireworks between the two crosses 17 on the base plate 1.

[0023] In this invention, during use, the fireworks are first placed on the base plate 1, so that the center of the bottom of the fireworks contacts the fixed plate 4, thus creating a gap between the two ends of the bottom of the fireworks and the base plate 1. Then, the motor 5 is started, driving the bidirectional screw 6 to rotate between the tops of the two support plates 2. The rotation of the bidirectional screw 6 causes the two threaded blocks 7 to move closer together at the bottom of the connecting rod 3. The movement of the two threaded blocks 7 causes the two electric telescopic rods 8 to move closer together between the two support plates 2. The movement of the two electric telescopic rods 8 causes the two pull rings 9 to move closer together between the two support plates 2. Then, through the two concave rings 16, the two rectangular cylinders 15 move closer together on the base plate 1. The movement of the two rectangular cylinders 15 causes the two crosses 17 to move closer together on the base plate 1, thus causing the four clamping plates 18 on the two crosses 17 to move closer together and clamp the fireworks. Then, the two electric telescopic rods 8 are started to retract, thereby causing the two pull rings 9 to move upward between the two support plates 2. The upward movement of the two pull rings 9 is transmitted through the two... A concave ring 16 pulls two rectangular cylinders 15 upward on the base plate 1. The upward movement of the two rectangular cylinders 15 drives two rectangular rods 14 upward on the base plate 1. The upward movement of the two rectangular rods 14 drives two rotating rods 12 upward within the two support plates 2. The upward movement of the two rotating rods 12 drives two moving blocks 11 upward within the two grooves 10. The upward movement of the two rotating rods 12 drives two gears 19 to rise outside the two support plates 2. When the two gears 19 move upward between the two sets of racks 20, they can easily rotate, thus easily driving the two rotating rods 12 to rotate within the two moving blocks 11. In turn, the rectangular rods 14 and rectangular cylinders 15 drive the two crosses 17 to rotate. The rotation of the two crosses 17 facilitates the rotation of the fireworks, making it convenient to rotate simultaneously when lifting the fireworks. This facilitates the detection of leaks in all directions of the fireworks, effectively preventing leaks in other areas of the fireworks, and thus effectively preventing the fireworks from exploding during transportation.

[0024] Additionally, it should be noted that due to the drive of the electric telescopic rod 8, the gear 19 and rack 20 will not fall due to the weight of the fireworks box after clamping, therefore, no limiting structure is required.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
