The sliding frame 2 is provided with a limiting mechanism, which can fix the height of the lifting block 212. The limiting mechanism includes an electromagnet 213 fixedly connected to the inside of the lifting block 212.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] In order to solve the problem that the existing weight lifting machines are mostly simple in structure during actual use, and cannot be adjusted according to actual conditions, which greatly affects the working effect, this embodiment discloses the following technical solutions, specifically as follows: Figure 1-Figure 5As shown, the output end of the driving motor 11 is fixedly connected to the positive and negative screw rods 111, and the left and right ends of the positive and negative screw rods 111 are threadedly connected to the sliding blocks 112, and the sliding blocks 112 are fixedly connected to the sliding frame 2, and the top of the sliding frame 2 is provided with a mounting block 23, and the interior of the mounting block 23 is fixedly connected to the magnet three 231, and the interior of the weight block 212 is slidably connected to the fixing block 232, and the bottom of the fixing block 232 is fixedly connected to the spring two 233, and one end of the spring two 233 is fixedly connected to the interior of the weight block 212, and the bottom of the fixing block 232 is fixedly connected to the magnet four 234, and the magnet four 234 slides with the mounting block 23, and the magnet four 234 magnetically cooperates with the magnet three 231. When the car needs to be lifted, the driving motor 11 can be started at this time, and the driving motor 11 drives the positive and negative screw rods 111 to rotate, thereby making the two groups The sliding block 112 moves, and the sliding block 112 drives the sliding frame 2 to move, thereby making the two groups of sliding frames 2 move inside the placement table 1. At this time, the spacing between the two groups of sliding frames 2 can be adjusted according to actual usage. When the adjustment is completed, the wheel of the car is located on the lifting block 212. At this time, the telescopic cylinder 211 can be started, and the telescopic cylinder 211 drives the lifting block 212 to move. The lifting block 212 rises, thereby making the magnet four 234 detach from the inside of the mounting block 23. At this time, the magnet four 234 loses the adsorption effect of the magnet three 231. Under the action of the spring two 233, the fixing block 232 pops out from the inside of the lifting block 212, thereby fixing the wheel and preventing the wheel from sliding during the rising process. The weight lifting machine can be adjusted according to actual conditions, thereby improving the use effect.

[0034] At the same time, in order to solve the problem that the existing weight lifting machines often lack a limiting structure and cannot fix the height of the vehicle body if a power outage occurs during use, the present embodiment also discloses the following solution: the electromagnet 213 is electrically connected to the telescopic cylinder 211, and the interior of the weight lifting block 212 is also fixedly connected to a spring 1 214, one end of the spring 1 214 is fixedly connected to a magnet 1 215, a limiting groove 22 is provided on the outer side of the fixed column 21, and the limiting groove 22 is provided with multiple groups, and the interior of the limiting groove 22 is fixedly connected to a magnet 221, and the magnet 221 is magnetically matched with the magnet 1 215. When the telescopic cylinder 211 is used, the telescopic cylinder 211 drives the weight lifting block 212 to move. When it moves to a certain position, one end of the weight lifting block 212 is aligned with the Quasi-limit slot 22, when a power outage occurs, the telescopic cylinder 211 loses power and the electromagnet 213 loses power. At this time, under the action of spring 1 214, magnet 1 215 moves to the inside of the limit slot 22. At this time, under the action of magnet 2 221, magnet 2 221 and magnet 1 215 produce an adsorption effect to prevent the movement of magnet 1 215 due to external force. When the telescopic cylinder 211 is started, the electromagnet 213 is energized, and then a magnetic force is generated to have an adsorption effect on magnet 1 215. At this time, magnet 1 215 is disengaged from the inside of the limit slot 22, and the weight block 212 can rise and fall freely, thereby achieving the effect of fixing the height of the weight block 212 in the case of power outage, which is convenient for use.
