DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a retractable explosion-proof safety box, including a box body 1, a slide rail mechanism 2 is arranged on the inner surface of the box body 1, and a clamping mechanism 3 is arranged on the inner surface of the box body 1;

[0021] The slide rail mechanism 2 includes an outer fixed rail 201, a fixing bracket 202, a first limiting block 203, precision steel balls 204, an intermaxillary fixed rail 205, a retainer 206, a second limiting block 207 and an inner fixed rail 208. The outer fixed rails 201 are installed on both sides of the inner surface of the box body 1. A first limiting block 203 is fixedly connected to one side surface of the outer fixed rail 201. A fixing bracket 202 is fixedly connected to the inner side surface of the outer fixed rail 201. Precision steel balls 204 penetrate through the upper and lower surfaces of the fixing bracket 202. The outer wall of the precision steel ball 204 is in contact connection with the intermaxillary fixed rail 205. A retainer 206 is installed on one side surface of the intermaxillary fixed rail 205. A second limiting block 207 is fixedly connected to one side surface of the retainer 206 in a tight manner. An inner fixed rail 208 is in contact connection with one side surface of the second limiting block 207. Through the settings of the outer fixed rail 201, the fixing bracket 202, the first limiting block 203, the precision steel balls 204, the intermaxillary fixed rail 205, the retainer 206, the second limiting block 207 and the inner fixed rail 208, when in use, first, the inner fixed rail 208 undergoes a horizontal displacement under the action of a tensile force. At the same time, the precision steel balls 204 penetrating through the retainer 206 rotate, which reduces the frictional force generated during the displacement of the inner fixed rail 208. When the tail of the inner fixed rail 208 moves to the second limiting block 207 and is squeezed by it, the intermaxillary fixed rail 205 begins to undergo a horizontal displacement together with the inner fixed rail 208. The surface of the precision steel balls 204 penetrating through the fixing bracket 202 is in close contact with the outer wall of the intermaxillary fixed rail 205. The precision steel balls 204 penetrating through the fixing bracket 202 start to rotate while the intermaxillary fixed rail 205 undergoes a displacement, reducing the moving frictional force received by the intermaxillary fixed rail 205 until the tail of the intermaxillary fixed rail 205 is squeezed by the first limiting block 203. At this time, the intermaxillary fixed rail 205 and the inner fixed rail 208 stop displacement under the action of the first limiting block 203, and the box body 1 is in an open state. The above process solves the problems that most explosion-proof boxes in the current market have a single structure, limited storage space, cannot be deformed to improve the storage capacity and storage space, resulting in a large space occupied by the box body, a high space requirement, and cannot temporarily store and organize various flammable and explosive items, leading to low use efficiency of the explosion-proof box.

[0022] Furthermore, the clamping mechanism 3 includes a drawer 301, a fixing plate 302, a first telescopic rod 303, a spring 304, and a second telescopic rod 305. The inner surface of the box body 1 is provided with a drawer 301. The inner surface of the drawer 301 is closely attached to a fixing plate 302. One end of the fixing plate 302 is fixedly connected to a first telescopic rod 303. One side surface of the fixing plate 302 is fixedly connected to a spring 304 at the top. The inner wall of the spring 304 is closely attached to a second telescopic rod 305. Through the arrangement of the drawer 301, the fixing plate 302, the first telescopic rod 303, the spring 304, and the second telescopic rod 305, when storing flammable and explosive items, first push the fixing plate 302 to make it displace. At this time, the fixing plate 302 squeezes the spring 304 to cause it to undergo a compressive deformation. At the same time, the first telescopic rod 303 fixedly connected to one side surface of the fixing plate 302 displaces and begins to contract into the second telescopic rod 305. When the space between the two fixing plates 302 can accommodate flammable and explosive items, place the items and then remove the thrust. The spring 304 undergoes a recovery deformation, pushing the fixing plate 302 to displace in the direction of returning to the initial position until the fixing plate 302 squeezes the surface of the item and fixes its position, thereby achieving the position fixation of the stored items, and the clamping mechanism 3 can fix the positions of items of different sizes.

[0023] Furthermore, the intermaxillary fixed rail 205 and the outer fixed rail 201 form a telescopic structure, and the intermaxillary fixed rail 205 and the inner fixed rail 208 form a telescopic structure. Through the arrangement of the intermaxillary fixed rail 205, the connection between the outer fixed rail 201 and the inner fixed rail 208 is realized, so that the inner fixed rail 208 maintains stability during movement.

[0024] Furthermore, the outer wall size of the inner fixed rail 208 matches the size of the precision steel ball 204, and the inner wall size of the outer fixed rail 201 matches the size of the precision steel ball 204. Through the arrangement of the precision steel ball 204, when the inner fixed rail 208 and the intermaxillary fixed rail 205 displace, the friction force that hinders the displacement is reduced, thereby ensuring the stability of the operation of the slide rail mechanism 2.

[0025] Furthermore, the first limit block 203 can squeeze the bottom of the outer wall of the intermaxillary fixed rail 205, and the second limit block 207 squeezes the bottom of the inner wall of the inner fixed rail 208. Through the arrangement of the first limit block 203, the position limit of the maximum displacement of the movement of the intermaxillary fixed rail 205 can be ensured, and the intermaxillary fixed rail 205 will not derail, ensuring the stability of the operation of the slide rail mechanism 2.

[0026] Further, the second telescopic rod 305 and the first telescopic rod 303 form a telescopic structure. The inner diameter dimension of the second telescopic rod 305 matches the outer wall dimension of the first telescopic rod 303. Through the arrangement of the second telescopic rod 305 and the first telescopic rod 303, the direction of the spring 304 during deformation and recovery can be fixed, ensuring the stability of the spring 304 during use.

[0027] Further, the inner wall dimension of the spring 304 matches the outer wall dimension of the second telescopic rod 305. Both ends of the spring 304 are fixedly connected to the drawer 301 and the fixed plate 302 respectively. Through the arrangement of the spring 304, when the spring 304 recovers from deformation, the fixed plate 302 can squeeze the item, realizing the reinforcement of the item's position.

[0028] Working principle: When the retractable explosion-proof safety box is in use, first, the inner fixed rail 208 is subjected to a tensile force and undergoes a horizontal displacement. At the same time, the hardened steel balls 204 passing through the retainer 206 rotate, reducing the frictional force generated during the displacement of the inner fixed rail 208. When the tail of the inner fixed rail 208 moves to the second limit block 207 and presses against it, the intermaxillary fixed rail 205 begins to follow the inner fixed rail 208 and undergoes a horizontal displacement. The surface of the hardened steel balls 204 passing through the fixed frame 202 is in close contact with the outer wall of the intermaxillary fixed rail 205. The hardened steel balls 204 passing through the fixed frame 202 start to rotate while the intermaxillary fixed rail 205 is displaced, reducing the moving frictional force on the intermaxillary fixed rail 205 until the tail of the intermaxillary fixed rail 205 presses against the first limit block 203. At this time, the intermaxillary fixed rail 205 and the inner fixed rail 208 stop displacement under the action of the first limit block 203, and the box body 1 is in an open state. The above process solves the problems that most explosion-proof boxes on the market today have a single structure, limited storage space, cannot be deformed to improve storage capacity and storage space, resulting in a large occupied space of the box body, high space requirements, and cannot temporarily store and organize various flammable and explosive items, leading to low use efficiency of the explosion-proof box. When storing flammable and explosive items, first push the fixed plate 302 to make it displace. At this time, the fixed plate 302 squeezes the spring 304, causing it to undergo compressive deformation. At the same time, the first telescopic rod 303 fixedly connected to one side surface of the fixed plate 302 undergoes displacement and begins to contract into the second telescopic rod 305. When the space between the two fixed plates 302 can accommodate flammable and explosive items, place the items and then remove the thrust. The spring 304 undergoes recovery deformation, pushing the fixed plate 302 to displace in the direction of returning to the initial position until the fixed plate 302 presses against the surface of the item and is in a state of reinforcing its position, thereby achieving the position fixation of the stored items, and the clamping mechanism 3 can reinforce the positions of items of different sizes.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
