Description
Technical field
The utility model is related to technical field of jacks, more particularly to a kind of screw-driven formula fine-adjustment jack.
Background technology
Screw jack is widely used in the occasions such as factory, warehouse, harbour, power station, logging headquarter, is that raising carries thing
Product, one of optimal crane gear is by screw pair gear transmission, screw rod or ut socket to be used as top lift part by manpower.Tradition
Screw-driven formula jack dismounting step and its cumbersome, some can not even be dismounted, meanwhile, the most structure of traditional jack
Complicated, size is larger, therefore is not suitable in less space.
Utility model content
In order to solve the above-mentioned technical problem there is provided a kind of convenient disassembly, adaptable screw-driven formula fine-adjustment jack,
The utility model provides following technical scheme：
A kind of screw-driven formula fine-adjustment jack, including nut, screw rod, bearing, adjusting nut and fixing nut；The branch
Seat include substrate and with the integrally formed cylindrical portion of substrate, the round rectangle plate of screwed hole is provided with centered on the substrate,
The cylindrical portion center is also equipped with screwed hole, and the screwed hole surrounding of the substrate is additionally provided with mounting hole；The screw rod and branch
Seat threaded connection, composition transmission；The screw rod is nested in inside nut close to one end of substrate, and can be inside nut freely
Move but nut can not be departed from；The screw rod is threadedly coupled with adjusting nut, fixing nut successively close to one end of cylindrical portion,
The fixing nut is used for fixed adjustment nut, prevents it from releasing closer to screw rod end, described fixing nut；Described spiral shell
Cap on the one hand convenient transmission, on the other hand can also protect carrying body surface, it is to avoid direct friction.
The adjusting process of jack of the present utility model is：Bearing is fixed in equipment by mounting hole nesting first,
Then screw rod, adjusting nut and fixing nut are installed successively, because jacking bracket is nested into equipment, mounting hole is with top
It is regulation space to divide, therefore it is in less space, still with stronger applicability.Jack nut connects with load-carrying
Touch, it is that the displacement that load-carrying can be achieved is adjusted to rotate adjusting nut by spanner.
Further, the adjusting nut and fixing nut are interior chamfering nut, are easy to the screw-in of nut, easy disassembly.
Further, one end that the screw rod is connected with nut is provided with flange, can prevent screw rod from departing from nut.
Further, the screw rod be provided with close to one end of cylindrical portion it is stepped, and with the spiral shell of adjusting nut junction
Shank diameter is more than screw diameter with fixing nut junction, is to distinguish adjustment spiral shell by screw rod one end setting stepped one
Female and fixing nut, prevents operation mistiming from fixing nut is treated as into adjusting nut；Two be reduce spanner rotation when adjusting nut with
Friction before fixing nut, prevents fixing nut from following adjusting nut to rotate together with.
The beneficial effects of the utility model are：Adjustment and fixed form more easy disassembly using double nut, and knot
Structure is simple and reliable；As equipment appurtenance, its improvement for installing logic causes jack still has in less space stronger
Applicability.

Embodiment
A kind of screw-driven formula fine-adjustment jack as shown in Figure 1-2, including nut 1, screw rod 2, bearing 3, adjusting nut 5
And fixing nut 6；The bearing 3 include substrate 31 and with the integrally formed cylindrical portion of substrate 31 32, during the substrate 31 is
The heart is provided with the round rectangle plate of screwed hole 33, and the center of cylindrical portion 32 is also equipped with screwed hole 33, the spiral shell of the substrate 31
The surrounding of pit 33 is additionally provided with mounting hole 4, and mounting hole 4 described in the present embodiment sets 4；The screw rod 2 connects with the screw thread of bearing 3
Connect, constitute transmission；The screw rod 2 is nested in inside nut 1 close to one end of substrate 31, and can freely be transported in the inside of nut 1
Move but nut 1 can not be departed from；The screw rod 2 connects with adjusting nut 5, the screw thread of fixing nut 6 successively close to one end of cylindrical portion 32
Connect, the fixing nut 6 is used for fixed adjustment nut 5, prevents it from releasing closer to the end of screw rod 2, described fixing nut 6；
On the one hand described nut 1 facilitates transmission, on the other hand can also protect carrying body surface, it is to avoid direct friction.It is described to adjust
Whole nut 5 is interior chamfering nut with fixing nut 6, is easy to the screw-in of nut, easy disassembly.
The screw rod 2 is provided with flange with one end that nut 1 is connected, and can prevent screw rod 2 from departing from nut 1.The screw rod 2
It is provided with stepped, and is more than and fixing nut 6 with the diameter of screw rod 2 of the junction of adjusting nut 5 close to one end of cylindrical portion 32
The diameter of screw rod 2 of junction, is in order to distinguish adjusting nut 5 and fixing nut 6, to prevent by the one end of screw rod 2 setting stepped one
Only fixing nut 6 is treated as adjusting nut 5 by operation mistiming；Two be when reducing spanner rotation before adjusting nut 5 and fixing nut 6
Friction, prevent fixing nut 6 from following adjusting nut 5 to rotate together with.
Bearing 3 is fixed in equipment by the nesting of mounting hole 4 first, then screw rod 2, the and of adjusting nut 5 are installed successively
Fixing nut 6, because jacking bracket 3 is nested into equipment, the above section of mounting hole 4 be regulation space, therefore its
In less space, still with stronger applicability.Jack nut 1 is contacted with load-carrying, and adjusting nut 5 is rotated by spanner
The displacement regulation of load-carrying can be achieved.
Using above-mentioned foundation the utility model desirable embodiment as enlightenment, pass through above-mentioned description, relevant staff
Various changes and amendments can be carried out in the range of without departing from this utility model technological thought completely.This practicality
New technical scope is not limited to the content on specification, it is necessary to determine that its is technical according to right
Scope.
