Detailed Description
As shown in fig. 1-5, the utility model discloses:
a vertical lifting mechanism of an electric shifting machine comprises a base, an inner upright post 1 and an outer upright post 2 sleeved outside the inner upright post 1, wherein the lower end of the inner upright post 1 is fixed on the base, the outer upright post 2 can slide up and down relative to the inner upright post 1, a sliding block group is arranged in a gap between the inner upright post 1 and the outer upright post 2, the sliding block group consists of a fixed sliding block 31 and an adjusting sliding block, the adjusting sliding block consists of a wear-resistant gasket 32, a fixed flange 33 and an adjusting bolt 34, the fixed sliding block 31 and the fixed flange 33 of the adjusting sliding block are fixed on the column wall of the inner upright post 1 or the fixed flange 33 of the fixed sliding block 31 and the adjusting sliding block is fixed on the column wall of the outer upright post 2, the fixed flange 33 penetrates through and is fixed on the column wall of the inner upright post 1 or the outer upright post 2, a threaded hole 331 communicated with two sides of the column wall of the inner upright post 1 or the outer upright post 2 is arranged in the middle part of the fixed flange 33, and the external thread of a screw rod 342 of the adjusting bolt is matched with the internal thread of the threaded hole 331, the head 341 of the adjusting bolt is located on one side of the threaded hole 331, the wear-resistant gasket 32 is located on the other side of the threaded hole 331, and one end of the adjusting bolt 34 away from the head 341 of the adjusting bolt is rotatably connected with the wear-resistant gasket 32 in the circumferential direction of the threaded hole 331 and is fixedly connected with the threaded hole 331 in the axial direction.
Between the adjusting bolt 34 and the wear-resistant pad 32, the adjusting bolt 34 and the wear-resistant pad 32 can only rotate relatively in the circumferential direction of the adjusting bolt 34, but in the axial direction of the adjusting bolt 34, the positional relationship between the adjusting bolt 34 and the wear-resistant pad 32 is relatively fixed, and through the relative rotation between the adjusting bolt 34 and the threaded hole 331, the depth of the adjusting bolt 34 inserted into the threaded hole 331 can be adjusted, and further the distance between the wear-resistant pad 32 and the column wall where the threaded hole 331 is located can be adjusted. Taking the threaded hole 331 located on the column wall of the inner column 1 as an example, the head 341 of the adjusting bolt is located on the inner side of the inner column 1, the wear-resistant gasket 32 is located on the outer side of the inner column 1, the side surface of the wear-resistant gasket 32 far away from the inner column 1 contacts with the inner side of the outer column 2, the threaded hole 331 penetrates through the inner column 1, when the gap between the inner column and the outer column is too large, the side surface of the wear-resistant gasket 32 far away from the inner column 1 does not contact with the inner side of the outer column 2, the inner column and the outer column can shake, at this time, the adjusting bolt 34 is screwed in towards the direction of the outer column 2, and the adjusting bolt 34 pushes the wear-resistant gasket 32 towards the outer column 2, so that the wear-resistant gasket 32 contacts with the inner side of the outer column 2; when the gap between the inner and outer columns is small, the pressure between the side surface of the wear-resistant gasket 32 far away from the inner column 1 and the inner side of the outer column 2 is large, the friction force is increased, the sliding between the inner and outer columns is not smooth, and only the adjusting bolt 34 needs to be screwed out in the direction far away from the outer column 2. Conversely, the threaded hole 331 is located on the column wall of the outer column 2, and the adjusting slide block can also play the same role.
As shown in figure 2 of the drawings, in which,
the fixed slide block 31 and the wear-resistant slide block of the same slide block group are positioned at two ends of the inner upright post 1 or the outer upright post 2 in the diameter direction.
As shown in figure 1 of the drawings, in which,
the clearance between interior stand 1 and the outer stand 2 is equipped with two sets of slider groups of first slider group 3a and second slider group 3b, and first slider group 3a is fixed in the upper end outside of interior stand 1, and the second slider group 3b is fixed in the lower extreme inboard of outer stand 2.
Two-point support is formed by the two sets of sliding block groups in the axial direction of the inner and outer upright posts, so that the support between the inner and outer upright posts of the sliding block groups is more stable, and the length of the sliding blocks in the axial direction of the upright posts is not required to be too large. When the lifting mechanism rises, the lower end of the outer upright post 2 slides upwards, and slides towards the upper end of the inner upright post 1, the first sliding block group is fixed at the outer side of the upper end of the inner upright post, the second sliding block group is fixed at the inner side of the lower end of the outer upright post, so that the inner upright post and the outer upright post can be lifted, and the two sliding block groups can be located between the outer upright posts.
As shown in figures 6 and 7 of the drawings,
specifically, the middle part of wear-resisting gasket 32 is equipped with the step hole, the one end that the head was kept away from to adjusting bolt 34 is equipped with spliced pole 343, in wear-resisting gasket 32 to adjusting bolt 34's direction, the step hole includes first hole section 3211 and second hole section 3212 in proper order, and the spliced pole includes first post section 3431 and second post section 3432, and the internal diameter of first hole section 3211 is greater than the internal diameter of second hole section 3212, and the external diameter of first post section 3431 cooperatees with the internal diameter of first hole section 3211, and the external diameter of second post section 3432 cooperatees with the internal diameter of second hole section 3212.
During use, the connecting column 343 is inserted into the stepped hole, the first column section 3431 is located in the first hole section 3211, the second column section 3432 is located in the second hole section 3212, the connecting column 343 can rotate in the stepped hole, and the end face of the adjusting bolt 34 far away from the head is abutted against the wear-resistant gasket 32. The above arrangement achieves the function that the adjusting bolt 34 and the wear-resistant shim 32 can only be rotated relative to each other in the circumferential direction of the adjusting bolt 34 and fixed in the axial direction.
The side face, close to the adjusting bolt, of the wear-resistant gasket 32 is provided with a cylindrical protrusion 321, the stepped hole is formed in the protrusion 321, and the outer diameter of the protrusion 321 is smaller than the inner diameter of the threaded hole 331.
The end surface of the adjusting bolt far away from the head part is abutted against the end surface of the protrusion 321. The protrusion 321 can extend into the threaded hole 331, the inner diameter of the threaded hole 331 is slightly larger than the outer diameter of the protrusion 321, and in the diameter direction of the threaded hole 331, the shaking between the connecting column 343 and the stepped hole can be reduced, so that the connection stability between the wear-resistant gasket 32 and the fixed flange 33 is improved.
The fixed sliding block 31 and the wear-resistant gasket 32 of the adjusting sliding block are made of POM plastic.
