Abstract
The utility model relates to a kind of device utilizing screw rod to realize lifting, comprise and be shaped with externally threaded screw rod, the female nut of spinning system on screw rod, the female screw sleeve of spinning system on screw rod square under the nut, and, the screw thread of described screw rod, nut and screw sleeve matches, and the spacing of screw thread is identical with the amount of movement precision being lifting object.The utility model just can implement device flexible only by handmade rotary screw rod or screw sleeve, and the lower surface of screw sleeve or the upper surface of screw rod are fixed on somewhere, just can reach the object that less load is elevated, the utility model apparatus structure is simple, cost is low, safe and reliable to operation.
Description
Technical field
The utility model belongs to machine applications equipment technical field, particularly a kind of device utilizing screw rod to realize lifting.
Background technology
The jacking system of current use generally all adopts hydraulic pressure, the means such as pneumatic, electronic, for fast very convenient main equipment, but is not that very economical is convenient relative to then becoming less load; Also have some jacking systems to adopt latch to fix the position of load, fixing reliably insecure like this for load, and there will be the phenomenon of wearing and tearing.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of device utilizing screw rod to realize lifting.
The utility model solves its technical matters and takes following technical scheme to realize:
Utilize screw rod to realize a device for lifting, comprise and be shaped with externally threaded screw rod, the female nut of spinning system on screw rod, the female screw sleeve of spinning system on screw rod square under the nut.
And the screw thread of described screw rod, nut and screw sleeve matches, the spacing of screw thread is identical with the amount of movement precision being lifting object.
Advantage of the present utility model and good effect are:
1, the utility model just can implement device flexible only by handmade rotary screw rod or screw sleeve, and the lower surface of screw sleeve or the upper surface of screw rod are fixed on somewhere, just can reach the object that less load is elevated.
2, the utility model apparatus structure is simple, cost is low, safe and reliable to operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
Utilize screw rod to realize a device for lifting, as shown in Figure 1, comprise and be shaped with externally threaded screw rod 1, the female nut 2 of spinning system on screw rod, the female screw sleeve 3 of spinning system on screw rod square under the nut.
In concrete enforcement of the present utility model, described screw rod, the screw thread of nut and screw sleeve matches, the spacing of screw thread is according to being lifting the amount of movement of object and being decided to be precision and determining, if flight pitch is too close, the time of rotary screw or screw sleeve will be very long, inconvenient, if flight pitch is too large, be far longer than the amount of movement precision being lifting object, then determine that the accurate location being lifting object is very difficult again by rotary screw or screw sleeve, drawn by repetition test, when the spacing of screw thread is identical with the amount of movement precision being lifting object, adjustment is lifting the amount of movement of object and accurately location is the most convenient, reliably.
Principle of work:
The lower surface of screw sleeve or the upper surface of screw rod are fixed on somewhere, the upper surface of screw rod or the lower surface of screw sleeve connect load, when needing the height changing load, after manual rotation screw rod or screw sleeve make it reach the position of anticipation, the upper surface of screw sleeve is screwed onto again with nut, screw rod is locked.
Claims (1)
1. the device utilizing screw rod to realize lifting, it is characterized in that: comprise and be shaped with externally threaded screw rod, the female nut of spinning system on screw rod, the female screw sleeve of spinning system on screw rod square under the nut, wherein, the screw thread of described screw rod, nut and screw sleeve matches, and the spacing of screw thread is identical with the amount of movement precision being lifting object.
