Detailed Description

The utility model is described in further detail below with reference to the figures and specific embodiments.

As shown in fig. 1 to 5, a levelling rod assists bed hedgehopping device, including positioning disc 1, positioning disc 1 is close to the fixed first nut 2 that is equipped with in the circumference outside, 3 screw-thread fit of first nut 2 and the first screw rod of vertical setting, 3 bottoms of first screw rod are equipped with pressure disk 4, 1 central point of positioning disc puts the fixed second nut 5 that is equipped with, 6 screw-thread fit of second nut 5 and the second screw rod of vertical setting, 6 tops of second screw rod are equipped with location ball 7, and 1 both sides parallel fixation of positioning disc is equipped with limiting plate 8, be equipped with the tight dish 9 in telescopic top on the limiting plate 8.

Preferably, a first knob 10 is further fixedly arranged at the top of the first screw rod 3. The first screw 3 can be turned more easily by the first knob 10, facilitating its adjustment.

Preferably, a second knob 11 is fixedly arranged on the surface of the second screw rod 6. The second screw 6 can be turned more easily by the second knob 11, facilitating its adjustment.

Preferably, the tight dish 9 tip of top and the 12 one end fixed connection of third screw rod that transversely set up, the 12 other ends of third screw rod pass third nut 13 and rather than screw-thread fit, and third nut 13 one side surface is spacing in limiting plate 8 through bearing 14, and the fixed rotary disk 15 that is equipped with in 13 other side surfaces of third nut, the articulated rotatory handle 16 that is equipped with in 15 avris of rotary disk. The adjusting process of the jacking disc 9 is concretely; firstly holding the third screw 12 to prevent the third screw from rotating, then rotating the rotating handle 16 to drive the rotating disc 15 to rotate and further drive the third nut 13 to rotate, and since the third nut 13 is in threaded fit with the third screw 12 and the third screw 12 is limited to rotate at the moment, the third screw 12 can only axially move, so as to drive the tightening disc 9 to be close to or far away from the leveling rod 17. Because the third screw 12 can move axially without rotating, the tightening disc 9 can not rotate in the process of moving axially, and thus when the tightening disc 9 contacts and presses the surface of the leveling rod 17, relative friction with the surface of the leveling rod 17 due to rotation can not be generated, and damage to the surface of the leveling rod 17 by the tightening disc 9 can be effectively avoided.

Preferably, each limiting plate 8 is provided with two tightening discs 9.

The working principle of the embodiment is as follows:

firstly, placing the whole heightening device at a measuring position, adjusting a first screw rod 3 to rotate in a first nut 2 through a first knob 10 so as to enable a pressure plate 4 to be in contact with the ground, adjusting a second screw rod 6 to rotate in a second nut 5 through a second knob 11 so as to adjust the height of a positioning ball 7 positioned at the top, and after the adjustment process is completed, placing the bottom of a leveling rod 17 on the positioning ball 7 as shown in fig. 5; then hold the third screw 12, prevent its rotation, then rotate the rotating handle 16, thus drive the rotating disc 15 to rotate, and then drive the third nut 13 to rotate, because the third nut 13 cooperates with the third screw 12 whorl, and the third screw 12 is restricted to rotate at this moment, so the third screw 12 can only move axially, thus drive the tightening plate 9 to be close to and compress the levelling rod 17, because the third screw 12 can move axially without rotating, so the tightening plate 9 will not rotate in the course of moving axially, when the tightening plate 9 contacts and compresses the surface of the levelling rod 17, will not produce the relative friction with the surface of the levelling rod 17 because of rotating, in this way, can avoid the damage of the surface of the levelling rod 17 to the tightening plate 9 effectively.
