Balance pier block height adjusting device

[0018]In order to facilitate the understanding of those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

[0019]Such asFigure 1-2The shown height adjustment device of a balance pier includes a mounting hole 2 provided on a mold body 1, and a height-adjustable top block 3 is arranged in the mounting hole 2 and the top block 3 is away from the mounting hole A gasket 6 is placed at one end of the mounting hole 2 and the top block 3 is provided with a set connection, the inner bottom surface of the mounting hole 2 is fixedly mounted with a first electromagnet 9, and the top block 3 is close to the One end of the mounting hole 2 is equipped with a second electromagnet 10 that is matched with the first electromagnet 9. The set includes an outer sleeve 4 and an inner sleeve 5, and both the inner sleeve 5 and the outer sleeve 4 are made of non-magnetic materials. After the processing is completed, the outer sleeve 4 and the inner sleeve 5 are screwed together. At the same time, the first electromagnet 9 and the second electromagnet 10 have the same magnetic poles on the side close to each other. Using the same magnetic principle of mutual repulsion, the first The repulsive force generated between the electromagnet 9 and the second electromagnet 10 can effectively neutralize the pressure on the top block 3 during the stamping process, and can effectively reduce the damage of the thread between the inner sleeve 5 and the outer sleeve 4 due to excessive impact. The adsorption of the second electromagnet 10 on the top block 3 can not only prevent the inner sleeve 5 from detaching from the top block 3 under its own gravity, but also magnetize the top block 3 to achieve the purpose of adsorbing the gasket 6, which can effectively prevent the gasket 6 from detaching from the top block 3.

[0020]A number of uniformly distributed screws 7 are fixedly connected between the outer casing 4 and the side wall of the mounting hole 2. The screws 7 are located on the upper end surface of the side wall of the mounting hole 2, and one end of the inner sleeve 5 is provided with a card slot, so The end of the top block 3 away from the mounting hole 2 is provided with a clamping block that cooperates with the clamping slot, and the relative rotation of the inner sleeve 5 and the mounting block is restricted by the cooperation of the clamping slot and the clamping block, so that the The inner sleeve 5 can be detachably installed on the outer side wall of the top block 3; the top block 3 and the gasket 6 are made of magnet absorbable materials, and the attraction between the top block 3 and the second electromagnet 10 The inner sleeve 5 is fixedly installed on the top block 3; the installation hole 2 and the outer sleeve 4 are provided with a through groove 8 communicating with the outside, and the installation hole 2 is connected with the through groove 8 on the outer sleeve 4 Coinciding, the second electromagnet 10 is provided with a limit block that can move freely in the through slot 8, and the second electromagnet 10 is adsorbed on the end of the top block 3 close to the mounting hole 2; wherein The adjustment height of the top block 3 can be determined by evenly distributing 2-4 sets of scale lines on the outer surface of the inner sleeve 5; at the same time, the upper end of the through groove 8 of the inner sleeve 5 is closed, which can effectively avoid the second The electromagnet 10 is separated from the through slot 8 while cooperating with the limiting block can effectively prevent the second electromagnet 10 from reversing in the through slot 8.
