[0027] In the present application, the position of the slide rod 6 is fixed and arranged parallel to the I-rail 5. The driving mechanism 3 drives the frame 1 to slide on the I-rail 5, so that the slider 7 and the sleeve 8 can slide correspondingly along the slide rod 6, thereby ensuring the balance of the upper and lower ends of the frame 1 and preventing the frame 1 from tilting.

[0028] Furthermore, the supporting mechanism 2 also includes a lifting screw rod 201 and a guide rod 202. The lifting screw rod 201 is rotatably installed on one side of the side frame 4, and the guide rod 202 is fixedly installed on one side of the side frame 4. A connecting rod 203 is slidably sleeved on the guide rod 202. A screw sleeve 204 is fixedly installed inside the end of the connecting rod 203 away from the guide rod 202. The screw sleeve 204 is threadedly sleeved on the lifting screw rod 201. Both ends of the connecting rod 203 are fixedly connected to connecting seats 205. The two support rods 206 are respectively rotatably installed in the two connecting seats 205. The upper ends of the two support rods 206 are fixedly connected with screws 207. After one end of the screw 207 rotates and passes through the connecting seat 205, a screw sleeve 208 is threadedly sleeved, and the bottoms of the two support rods 206 are fixedly connected with anti-slip pads 209.

[0029] In the present application, after adjusting the position of the frame 1, the support rod 206 can be rotated in the connecting seat 205 by loosening the screw sleeve 208, and then the lifting screw rod 201 is rotated. Through the threaded cooperation between the lifting screw rod 201 and the screw sleeve 204, the screw sleeve 204 drives the connecting rod 203 to move downward, and the connecting rod 203 drives the two support rods 206 to move downward synchronously, and the two support rods 206 are stretched outward at a certain angle. When the anti-slip pad 209 is in contact with the ground, the screw sleeve 208 is tightened to fix the position of the support rod 206. Through this arrangement, the frame 1 can be supported from both sides, thereby improving the stability and safety of the frame 1 during use.

[0030] Furthermore, the driving mechanism 3 includes a handwheel 301, two transmission shafts 302 and a rotating rod 304, the two transmission shafts 302 are coaxially fixedly connected with the handwheel 301 and the rotating rod 304, respectively, the two transmission shafts 302 are sleeved with a transmission belt 303, one end of the handwheel 301 and the rotating rod 304 are rotatably installed in the side frame 4, a mounting frame 9 is fixedly installed at the bottom of the frame body 1, the mounting frame 9 is fixedly installed on the base frame 11, and adjustment grooves 13 are opened on both sides of the base frame 11, the two rollers 10 are rotatably installed in the two U-shaped frames 12, respectively, the upper ends of the two U-shaped frames 12 are fixedly installed on the base frame 11 by fastening bolts 14, and the fastening bolts 14 are adjustably set in the adjusting grooves 13, the rotating rod 304 is located on the rod body inside the mounting frame 9 and is fixedly connected with two symmetrical worms 305, one side of the two worms 305 is respectively meshed with worm wheels 306, and the two worm wheels 306 are respectively coaxially fixedly connected with the two rollers 10.

[0031] In the present application, when adjusting the position of the frame 1, the transmission shaft 302 is driven to rotate by rotating the hand wheel 301, the rotating rod 304 and the worm 305 are driven to rotate synchronously by the transmission belt 303, and the worm gear 306 is driven to rotate by the worm 305, thereby driving the two rollers 10 to move along the two side walls of the I-rail 5 to realize the movement of the frame 1.

[0032] By setting an adjustment groove 13 on the base frame 11, the fastening bolt 14 can move in the adjustment groove 13 to adjust the position of the rollers 10 on both sides, ensure that the rollers 10 are tightly against the I-rail 5, avoid loose connection causing jamming or bumps during movement, and adjust when the surface of the roller 10 is worn to extend the service life of the equipment. After adjusting the position of the roller 10, tighten the fastening bolt 14 to fix the position of the U-frame 12 and the roller 10.

[0033] During specific configuration, a shock absorber may be installed on the roller 10 to reduce vibration and improve stability.

[0034] The working principle of this utility model:

[0035] The hand wheel 301 is turned to drive the transmission shaft 302 to rotate, and the transmission belt 303 drives the rotating rod 304 and the worm 305 to rotate synchronously, and the worm 305 drives the worm wheel 306 to rotate, thereby driving the two rollers 10 to move along the two side walls of the I-rail 5 to realize the movement of the frame 1. The slider 7 and the sliding sleeve 8 slide along the sliding rod 6 accordingly, thereby ensuring the balance of the upper and lower ends of the frame 1 and preventing the frame 1 from tilting. Then, the nut 208 is loosened to allow the support rod 206 to rotate in the connecting seat 205 , and then rotate the lifting screw rod 201, and through the threaded cooperation between the lifting screw rod 201 and the screw rod sleeve 204, the screw rod sleeve 204 drives the connecting rod 203 to move downward, and the connecting rod 203 drives the two support rods 206 to move downward synchronously, and the two support rods 206 are stretched outward at a certain angle. When the anti-slip pad 209 abuts against the ground, tighten the screw sleeve 208 to fix the position of the support rod 206, support the frame 1 from both sides, and improve the stability and safety of the frame 1 during use.

[0036] To sum up, this anti-tipping dense rack, by arranging a sliding bar 6 and a sliding block 7 at the upper end of the frame 1, can make the sliding block 7 slide along the sliding bar 6 accordingly when the frame 1 moves, thereby ensuring the upper and lower balance of the frame 1 and preventing the frame 1 from tipping over, thereby improving the safety of the frame 1; by arranging the supporting mechanism 2, the two supporting bars 206 can be opened outward after the frame 1 is adjusted, thereby supporting the frame 1 on both sides, improving the stability of the frame 1 and the strength of the sliding bar 6, and preventing the sliding bar 6 from deforming or tilting; by arranging an adjusting groove 13 on the base frame 11, the fastening bolt 14 can move in the adjusting groove 13, and the position of the rollers 10 on both sides can be adjusted to ensure that the rollers 10 are tightly against the I-rail 5, avoiding loose connection and causing jamming or bumping during movement; it can also be adjusted when the surface of the roller 10 is worn, thereby extending the service life of the equipment; after adjusting the position of the roller 10, the fastening bolt 14 is tightened to fix the position of the U-shaped frame 12 and the roller 10.
