In figure: casing 6, standpipe 34, interior dental structure 38, lock screw 39, first wire nut 35, our department 351, alar part 352, recessed
Fall into area 353, the first screw rod 27, screw 28, spline housing 29, the second screw rod 31, the second screw 32, limited block 33, bearing 40.
Specific embodiment
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model.
Shown in please referring to Fig.1 to Fig.3, a kind of screw body is present embodiments provided, comprising: the first screw component is arranged
31 component of the second screw rod on the outside of the first screw component, and it is set in the casing 6 on the outside of 31 component of the second screw rod；Casing 6
The accommodating space for the first screw component and the second screw component is formd, which is specifically being assemblied in lifting pipe structure
It, can be directly by casing 6 and the first screw component and the second screw component structure and lifting pipe other structures as a whole when middle
Assembly, it is not only easy to use, but also maintenance easy to disassemble.
Specifically, it screw rod 27 and the first wire nut 35 that is set on the first screw rod 27 that first order screw component, which includes first,；
First wire nut 35 is connected by the one end fastening axial with casing 6 of lock screw 39；Second and screw component include be set in
The second of the outside of first screw rod 27 screw rod 31 and the second screw 32 for being set on the second screw rod 31；The one of second screw rod, 31 axial direction
End is rotatedly connected with first wire nut 35.
The second screw rod 31 in the present embodiment be with 27 synchronous rotary of the first screw rod, specifically, remote in the first screw rod 27
End from first wire nut 35 passes through the spline housing 29 that screw 28 is fixed with；And second screw rod 31 inner sidewall be equipped be suitable for
Nested interior dental structure 38 is adapted to spline housing 29.Since dental structure 38 agrees in 31 inner sidewall of spline housing 29 and the second screw rod
Matching effect, allows the second screw rod 31 with 27 synchronous rotary of the first screw rod.
First wire nut 35 includes our department 351 with the socket of the first screw rod 27, and is integrally provided on a ring in 351 outside of our department
The alar part 352 of shape structure；The depressed area 353 of ring structure is formed between our department 351 and alar part 352；Second screw rod 31
End is connected in insertion depressed area 353 with alar part 352；In the end of the second screw rod 31 by bearing 40 and alar part 352 towards originally
The side in portion 351 is connected.That is for the second screw rod 31 during rotating with the first screw rod 27, the second screw rod 31 can be relative to the
The smooth rotation of one screw 35, allows the second screw rod 31 to do the axis direction relative to the second screw 32 with first wire nut 35
Elevating movement.Mode that the first screw rod 27 and 31 synergistic combination of the second screw rod used be connected compared with the existing technology in individually
For one screw rod, the first screw rod 27 extends the axial length of the second screw rod 31, and the first screw rod 27 can also make second
The rotation of the second screw rod 31 can be effectively ensured by the opposite supporting role power of the first screw rod 27 in the radial direction in the rotation of screw rod 31
Stability during turning, even if such structure to be not provided with bearing far from the end of first wire nut for the second screw rod 31
Also it can guarantee the stability of the second screw rod 31 rotation.
In order to limit casing 6 with first wire nut 35 is moved up and down relative to the first screw rod 27 when track, improve set
The stability that pipe 6 is gone up and down is equipped with a limited block 33 in the separate end outer sheath being connected with first wire nut 35 of the second screw rod 31；
Second screw rod 31 is adapted to the rotation of limited block 33；Limited block 33 and the second screw 32 are uniform connected with standpipe 34；It is vertical
Pipe 34 and casing 6 are coaxially disposed.Limited block 33 and the second screw 32 and standpipe 34 at this time defines that the second screw rod 31 exists
Relative to the track that the second screw 32 is axially moved, prevent the second screw rod 31 and first wire nut 35 from driving in 6 moving process of casing
It shakes.
In order to reduce casing 6 during doing the elevating movement relative to standpipe 34 with first wire nut 35 with second
Rubbing to improve the smooth degree of the lifting of casing 6 between mother 32, second screw 32 of the present embodiment is away from the outer of the second screw rod 31
There is gap between side wall and the inner tubal wall of casing 6.
The present embodiment is to realize lifting of the lifting of casing 6 relative to standpipe 34 by the rotation of the first screw rod 27 of driving
Movement, first screw rod 27 of the present embodiment is connected to realize that Power Component drives the rotation of the first screw rod 27 with Power Component, this
The Power Component at place is using such as, but not limited to driving motor.
