[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: a high-strength steel strip quenching equipment, including a quenching box body 1, an external protective frame 2, a fixed base plate 3, support legs 4, a baffle plate component 5, a box plate component 6, a mounting groove 7, and a temperature detection screen 8. The quenching box body 1 is surrounded by an external protective frame 2, and the bottom of the external protective frame 2 is connected to the fixed base plate 3. Multiple support legs 4 are provided on the left and right sides of the fixed base plate 3. The box plate component 6 is installed on both the left and right sides of the external protective frame 2, and the box plate component 6 is connected to the mounting groove 7 on both sides of the quenching box body 1. A baffle plate component 5 is also provided around the right side of the box plate component 6. The baffle plate component 5 is installed on the external protective frame 2 and includes a baffle plate 51, a first connecting rod 52, a first movable buckle 53, a second movable buckle 54, and a third connecting rod 55. Two connecting rods 55, and the shielding plate 51 is provided with a first connecting rod 52 and a second connecting rod 55 on both sides. The first connecting rod 52 is connected to the inside of the shielding plate 51, and the second connecting rod 55 is connected to the outside of the shielding plate 51. The first movable buckle 53 and the second movable buckle 54 are both fixedly installed on the surface of the external protective frame 2. The first movable buckle 53 is connected to the first connecting rod 52, and the second movable buckle 54 is connected to the second connecting rod 55. The box panel component 6 includes a box door panel 61, a positioning plate 62, a telescopic rod 63, a small telescopic motor 64, and a fixing bolt 65. The top position of the box door panel 61 is fixedly connected to the positioning plate 62 by the fixing bolt 65, and the bottom end of the positioning plate 62 is also provided with a telescopic rod 63. The small telescopic motor 64 connected to the bottom of the telescopic rod 63 is installed on the top right side of the external protective frame 2.

[0020] As the first embodiment of this utility model: the temperature detection screen 8 is installed on the external protective frame 2 on both sides of the back of the quenching box body 1. This design, with the temperature detection screen 8 installed on the quenching box body 1, helps to monitor the quenching temperature inside the quenching box body 1 in real time and control the final quenching effect. The overall size of the shielding plate 51 meets the width of the right side of the external protective frame 2, and a heat-insulating material coating is added to the inner side of the shielding plate 51. This design, by adding a heat-insulating shielding plate 51, helps to prevent the heat waves inside the box from directly impacting the workers. The lengths of the first connecting rod 52 and the second connecting rod 55 meet the requirements of the external protective frame 2. The height of the quenching box body 1 on the protective frame 2 is such that the length of the second movable buckle 54 is greater than that of the first movable buckle 53, and the second connecting rod 55 is installed in the outer area of ​​the second movable buckle 54. This design, by installing different connecting rods on the shielding plate 51, helps to facilitate the placement and adjustment of the shielding plate 51. The structure is simple and practical. The size of the box door panel 61 matches the size of the mounting groove 7 on the right side of the quenching box body 1. This design uses a small telescopic motor 64 to drive the box door panel 61 to lift and open, and the addition of the mounting groove 7 ensures the positioning accuracy of the box door panel 61 when it is lifted and lowered.

[0021] As a second embodiment of this utility model: When quenching high-strength steel strip, the quenching box body 1 is used directly for quenching. The telescopic rod 63 is raised by a small telescopic motor 64, allowing the steel strip to enter the quenching box 1 through the box door panel 61 on the left side of the external protective frame 2. During the quenching process, the staff monitors the internal temperature of the quenching box body 1 with the help of the temperature detection screen 8 for easy control. After the steel strip is quenched, the shielding plate 51 is lowered. Driven by the connecting rods on the first movable buckle 53 and the second movable buckle 54 on both sides of the external protective frame 2, the shielding plate 51 will be fastened to the right side of the box door of the quenching box body 1. Then, the telescopic rod 63 is raised by the small telescopic motor 64, so that the box door panel 61 connected to it can slide up from the mounting groove 7. As the box door panel 61 is opened, the heat wave or splashing debris that rushes out of the quenching box body 1 at the moment of opening is blocked by the shielding plate 51 for protection, preventing the safety hazard of accidental injury from splashing.
