[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-4 This utility model provides an adjustable-width fireproof frame, including a base 1. An outer frame 2 is symmetrically and fixedly connected to the top of the base 1. Adjustment components 3 are provided at the front and rear ends of the outer frame 2. Each adjustment component 3 includes front and rear frames 301 slidably connected to the front and rear ends of the outer frame 2. Moving sliders 305 are symmetrically and fixedly connected to the side of the front and rear frames 301 closest to the base 1. Each moving slider 305 has a limiting groove 306 inside. Moving blocks 307 are fixedly connected between the moving sliders 305. A sliding groove 302 is provided inside the base 1, and limiting guide rails are symmetrically and fixedly connected inside the sliding groove 302. A bidirectional lead screw 304 is rotatably connected between the limiting guide rails 303 and inside the sliding groove 302. A moving block 307 is threadedly connected to the bidirectional lead screw 304. A stepper motor 308 is fixedly installed at the bottom of the placement base 1. The drive end of the stepper motor 308 is connected to the bidirectional lead screw 304 through a drive structure. An extension base plate 309 is fixedly connected inside the front and rear frames 301 and above the placement base 1. The drive structure includes a first transmission disk 3081 fixedly connected to the drive end of the stepper motor 308 and a second transmission disk 3083 fixedly connected to the bidirectional lead screw 304. The second transmission disk 3083 and the first transmission disk 3081 are connected by a transmission belt 3082.

[0023] When the width of the fireproof frame needs to be adjusted, the stepper motor 308 starts, and its drive end drives the transmission disk 3081 to rotate. The transmission disk 3081 transmits power to the transmission disk 3083 through the transmission belt 3082, causing the bidirectional lead screw 304 to rotate in the sliding groove 302. Since the front and rear ends of the side surface of the bidirectional lead screw 304 are respectively provided with threads in opposite directions, and the moving block 307 is threadedly connected to the bidirectional lead screw 304, the rotation of the bidirectional lead screw 304 will drive the moving block 307 to move relative to or towards each other. The moving block 307 drives the moving slider 305 to slide on the limiting guide rail 303. At the same time, the limiting groove 306 cooperates with the limiting guide rail 303 to guide and limit, so that the front and rear frames 301 can slide smoothly along the front and rear ends of the outer frame 2, realizing the adjustment of the width of the fireproof frame. The extension base plate 309 moves with the front and rear frames 301, providing a stable support surface for placing items. This utility model achieves automated adjustment of the width of the fireproof frame through the adjustment component 3 composed of a stepper motor 308 and a bidirectional lead screw 304, which is convenient and labor-saving to operate; the cooperation between the moving slider 305 and the limit guide rail 303 ensures the stability and accuracy of the adjustment process and improves the adjustment precision; the overall structure is compact and the components work together, enabling the fireproof frame to flexibly adapt to different width requirements.

[0024] Specifically, such as Figure 2 and Figure 3 As shown, the cross-section of the front and rear frames 301 is U-shaped, and the inner walls of the left and right sides of the front and rear frames 301 are provided with storage slots 4, which are adapted to the shape of the outer frame 2; the interior of the outer frame 2 is provided with ventilation slots 5, and the interior of the ventilation slots 5 is provided with several fence strips 6 in a linear array, and the cross-section of the fence strips 6 is a parallelogram.

[0025] The cross-section of the front and rear frames 301 is U-shaped, and the storage grooves 4 on the inner walls of their left and right sides are adapted to the shape of the outer frame 2. When adjusting the width of the fireproof frame, the outer frame 2 can be partially inserted into the storage grooves 4, reducing space occupation. The ventilation grooves 5 and the fence strips 6 inside the outer frame 2 allow air to circulate inside and outside the fireproof frame. At the same time, the parallelogram design of the cross-section of the fence strips 6 ensures ventilation effect and enhances the structural strength of the fence strips 6, effectively blocking some foreign objects from entering. The design of the storage grooves 4 in this utility model makes the fireproof frame more compact in structure during width adjustment, saving space. The cooperation between the ventilation grooves 5 and the fence strips 6 achieves good ventilation performance, and the parallelogram fence strips 6 balance strength and ventilation, improving the practicality of the fireproof frame.

[0026] Specifically, such as Figure 2 and Figure 3As shown, the bottom of the base 1 is fixedly connected to several support columns 7 in a circular array. A support platform 8 is fixedly connected to the bottom of each support column 7, and a rubber anti-slip pad is provided on the bottom of the support platform 8. The support columns 7 at the bottom of the base 1 raise the fireproof frame as a whole, maintaining a certain distance between the base 1 and the ground to prevent ground moisture from directly corroding the base 1. The support platform 8 increases the contact area with the ground, improving the stability of the fireproof frame. Furthermore, the rubber anti-slip pad at the bottom of the support platform 8 increases friction with the ground, further preventing the fireproof frame from sliding during use.

[0027] Specifically, such as Figure 2 As shown, the base 1 and the outer frame 2 are integrally formed structures, both made of stainless steel. The front and rear ends of the side surface of the bidirectional lead screw 304 are respectively provided with threads in opposite directions. The integral forming of the base 1 and the outer frame 2 enhances the connection strength between them, making the overall structure more robust and less prone to deformation. The use of stainless steel, with its high temperature resistance, corrosion resistance, and good fire resistance, ensures the stability and safety of the fireproof frame in harsh environments such as fires. The opposite threads at the front and rear ends of the side surface of the bidirectional lead screw 304 are key to realizing the relative or opposite movement of the front and rear frames 301, converting it into linear motion through threaded transmission to precisely adjust the width of the fireproof frame.

[0028] Working principle and usage process of this utility model:

[0029] When adjusting the width of the fireproof frame during actual operation, the stepper motor 308 at the bottom of the base 1 can be activated. Its drive end drives the transmission disk 3081 to rotate, and the power is transmitted to the transmission disk 3083 through the transmission belt 3082, causing the bidirectional lead screw 304 in the sliding groove 302 to rotate. Since the threads at the front and rear ends of the side surface of the bidirectional lead screw 304 are opposite, the moving block 307, which is threaded to the bidirectional lead screw 304, will drive the moving slider 305 to move relative to or towards each other on the limiting guide rail 303. The limiting slide groove 306 cooperates with the limiting guide rail 303 to ensure smooth movement, thereby allowing the front and rear frames 301 to slide along the front and rear ends of the outer frame 2. During the adjustment process, the outer frame 2 can partially enter the storage groove 4 of the front and rear frames 301, and the extended base plate 309 moves synchronously with the front and rear frames 301 to maintain support stability. At the same time, the ventilation groove 5 of the outer frame 2 and the parallelogram fence strip 6 enable air circulation and block foreign objects.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
