in the figure: a base 1; a boss 101; a threaded hole 102; an adjusting nut 2; polygonal shaft 201; an internal thread 202; a circular shaft 203; a screw 3; a threaded shaft 301; a groove 302; a top block 303; and a screw 4.

Detailed Description

Example 1

As shown in fig. 1 to 4, the height-adjustable cushion block comprises a base 1, a rotating adjusting nut 2 is arranged on the base 1, a screw rod 3 in threaded connection is arranged on the adjusting nut 2, a groove 302 is arranged on one side of the screw rod 3, a screw 4 is arranged on one side of the base 1, and the end of the screw 4 abuts against the groove 302. From this structure, place the cushion and need support regional below, rotate adjusting nut 2 through the spanner to make screw rod 3 lift adjustment, thereby support and lean on the object bottom that needs to support, after the altitude mixture control targets in place, through screw 4 locking in recess 302, lock this height, prevent that the back of the silk from sliding. According to the principle that 3 points which are not on the same straight line determine a plane, when the cushion block is used, 3 blocks are in a group, the stability of the supporting plane is guaranteed, and fine adjustment of the supporting plane is facilitated.

In the preferred scheme, the top of the base 1 is provided with a boss 101, one side of the boss 101 is provided with a threaded hole 102, the screw 4 is in threaded connection with the threaded hole 102, and the adjusting nut 2 abuts against the boss 101 to rotate. With the structure, the end part of the screw 4 abuts against the groove 302 to limit the rotation of the screw rod 3, when the adjusting nut 2 is rotated, the screw rod 3 can move up and down, and after the height is adjusted in place, the screw 4 is further screwed to abut against the groove 302, so that the movement of the screw rod 3 is fixed.

In a preferable scheme, one end of the adjusting nut 2 is provided with a polygonal shaft 201, the other end of the adjusting nut 2 is provided with a round shaft 203, internal threads 202 are arranged in the adjusting nut 2, the round shaft 203 abuts against the boss 101, and the screw rod 3 is in threaded connection with the internal threads 202. By the structure, the wrench is clamped on the polygonal shaft 201 to rotate, so that rotation and adjustment are facilitated, the adjusting nut 2 abuts against the boss 101 through the circular shaft 203 to be positioned, and when the adjusting nut 2 is driven to rotate, the screw rod 3 can be driven to carry out lifting adjustment.

In a preferred scheme, one end of the screw rod 3 is provided with a threaded shaft 301, the other end of the screw rod is provided with a top block 303, and the threaded shaft 301 is in threaded connection with the internal thread 202. With the structure, the top surface of the top block 303 is flat and abuts against the lower part of the object, the contact area is large, the support device can be used for supporting objects with different sizes, and extrusion marks generated due to small contact area can be reduced.

In a preferred scheme, a bearing is arranged between the adjusting nut 2 and the boss 101, and the adjusting nut 2 abuts against the boss 101 through the bearing to rotate. With the structure, the adjusting nut 2 abuts against the boss 101 through the bearing and rotates more smoothly.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and should not be considered as limitations of the present invention, and the protection scope of the present invention should be defined by the technical solutions described in the claims, and includes equivalent alternatives of technical features in the technical solutions described in the claims. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
