Description

Technical Field

[0001] The present application relates to the field of fireworks production, and more specifically, to a safety protection device for fireworks production. Background Art

[0002] Fireworks, also known as fireworks, fireworks, and firecrackers, are made from pyrotechnic powder and are used to produce sound, light, and color entertainment products. They are often used in grand ceremonies or performances.

[0003] Patent document CN216815201U discloses a safety device for fireworks production, comprising a housing, a lid, a support plate, a connecting strap, a pressure plate, a hinged seat, a first switch, a locking plate, a lock hole, a vertical plate, and a locking rod. To use the safety device, the housing is first moved to the fireworks production area. The lid is then hinged so that its rear surface rests against the top surface of the support plate, thereby raising the lid and tightening the connecting strap. When fireworks are added to the housing, they land on the pressure plate, which presses against a spring, causing it to descend around the hinged seat. This, in turn, drives the lid around the hinge via the connecting strap, allowing it to rest on the top surface of the housing. The lid then contacts the first switch, and the locking plate of the lid is positioned between the vertical plates. The first switch then controls the retraction of an electric cylinder, which in turn drives the locking rod through the connecting plate into the lock.

[0004] The mechanical components of the electric cylinder and locking mechanism in the above-mentioned application documents may fail during long-term use, affecting the reliability of the equipment. Utility Model Content

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Example 1

[0024] See also Figures 1-4 The present embodiment provides a safety protection device for fireworks production, including a production box 1, which serves as the main container for fireworks production and provides a safe and isolated environment to prevent accidents during the fireworks production process. A through opening 2 is opened on the front of the production box 1 to facilitate the placement of materials and the removal of products. A placement table 3 is fixedly connected to the bottom end of the interior of the production box 1. A main protection device is provided inside the production box 1, and the main protection device includes a transverse slide 41. The interior of the transverse slide 41 is opened on the inner wall of the production box 1. A motor 42 is fixedly connected to the outer wall of the production box 1. The inner wall of the transverse slide 41 is rotatably connected to a threaded rod 43. The outer wall of the threaded rod 43 is threadedly connected to a connecting block A44, which serves as an intermediary connecting the threaded rod 43 and the protective door 47 to transmit motion. The side of the connecting block A44 is rotatably connected to the protective door 47 via a pin.

[0025] A longitudinal slide groove 45 is provided on the inner wall of the production box 1 , and a slider 46 is slidably connected inside the longitudinal slide groove 45 , and the side surface of the slider 46 is rotatably connected to the protective door 47 via a pin shaft.

[0026] The connecting block A44 is slidably connected inside the transverse sliding groove 41 .

[0027] When the above-mentioned equipment is used, when it is necessary to produce fireworks inside the production box 1, the motor 42 is started to drive the threaded rod 43 to rotate, and the connecting block A44 threadedly connected to its outer wall will slide inward inside the horizontal slide groove 41, driving the upper end of the protective door 47 to move toward the interior of the production box 1. At the same time, the sliders 46 on both sides of the lower end of the protective door 47 will also slide upward inside the longitudinal slide groove 45. When the sliders 46 slide to be parallel to the horizontal slide groove 41, the protective door 47 will be transformed from a vertical state to a state parallel to the production box 1. At this time, the fireworks production raw materials can be placed on the upper end of the placement table 3 for processing. Before starting processing, the reverse operation is performed to restore the protective door 47 to a vertical state, thereby achieving a protective effect.

[0028] Example 2

[0029] See also Figures 1-4 On the basis of Example 1, the interior of the production box 1 is further provided with a secondary protective device to provide additional safety protection to prevent accidents. The secondary protective device includes a connecting block B51, which is threadedly connected to the outer wall of the threaded rod 43. The outer wall of the connecting block B51 is fixedly connected to a connecting rod 52, and the other end of the connecting rod 52 is fixedly connected to a moving rod 53. One end of the moving rod 53 is movable through the production box 1, and the other end of the moving rod 53 is fixedly connected to a protective plate 54, which is located in the upper end gap of the protective door 47 to provide an additional protective barrier.

[0030] The connecting block B51 is slidably connected inside the transverse sliding groove 41 .

[0031] The protection plate 54 is located at the rear side of the upper end gap of the protection door 47 .

[0032] When the above-mentioned equipment is in actual use, since the protective door 47 in the main protective device needs to be moved, there will be some gap between its upper end and the upper end of the production box 1. Therefore, when the protective door 47 is closed, when the threaded rod 43 therein rotates, the connecting block B51 threadedly connected to its outer wall will move in the same direction as the connecting block A44 inside the horizontal slide groove 41, and drive the moving rod 53 to move through the connecting rod 52, then the protective plate 54 will move at the same time. When the protective door 47 is closed, the protective plate 54 is located at the rear end of the gap at the upper end of the protective door 47, thereby completing the protective effect.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
