Abstract
This practicality is related to lifting technology field, more specifically to a kind of detent mechanism of screw mandrel.In the desk class platform, kitchen tools and household electrical appliance of existing lowering or hoisting gear, in process of rising or falling, screw mandrel easily rocks, and wears screw mandrel and related fittings, shortens the life-span.This practicality is a kind of detent mechanism, including platform, screw mandrel, gear-box and motor, screw mandrel, gear-box and motor are connected respectively on platform, connected between gear-box and motor by connecting rod, gearbox drive is driven by connecting rod, drive screw mandrel to rotate again, fixed block, the external screw thread of upper fixed block up and down are also threaded with described screw mandrel and is connected with the screw-internal thread fit of lower fixed block；The thin nut being threaded on fixed block is additionally provided between described fixed block up and down, thin nut is resisted against on lower fixed block, carries out the Distance positioning between fixed block up and down.Problem is rocked using what this practicality solved screw mandrel, reduces noise, extends the life-span of screw mandrel, reduce production cost.
Description
Technical field
This practicality is related to lifting technology field, more specifically to a kind of detent mechanism of screw mandrel.
Background technology
In the desk class platform, kitchen tools and household electrical appliance of existing lowering or hoisting gear, generally single motor driven gear case turns
It is dynamic, then two screw rod transmissions are driven, risen or fallen by screw mandrel band moving platform, because screw mandrel length is longer, in process of rising or falling
In, screw mandrel easily rocks, and wears screw mandrel and related fittings, shortens the life-span.
Utility model content
A kind of deficiency of this practical purpose aiming at prior art, there is provided detent mechanism that can prevent screw mandrel from rocking.
A kind of detent mechanism, including platform, screw mandrel, gear-box and motor, screw mandrel, gear-box and motor are connected respectively to flat
On platform, connected between gear-box and motor by connecting rod, gearbox drive is driven by connecting rod, then drive screw mandrel to rotate, it is described
Screw mandrel on be also threaded with the screw-internal thread fit of fixed block and lower fixed block, the external screw thread of upper fixed block and lower fixed block
Connection；Be additionally provided with the thin nut being threaded on fixed block between described upper fixed block and lower fixed block, thin nut against
On lower fixed block, the Distance positioning between fixed block and lower fixed block is carried out.
As further improving and supplementing to such scheme, this practicality also includes following additional technical feature：
Described screw mandrel, upper fixed block and lower fixed block coaxial inner conductor.
The tank material of described gear-box is the aluminum or aluminum alloy class material of lighter in weight.
At least provided with one group of relative plane on described upper fixed block and the external surface of lower fixed block.
It can reach following beneficial effect using the utility model：Efficiently solve screw mandrel rocks problem, reduces and makes an uproar
Sound, extends the life-span of screw mandrel, while reduces production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As Fig. 1 shows, the utility model is a kind of detent mechanism.
Detent mechanism described in the present embodiment, including platform 1, screw mandrel 2, gear-box 3 and motor 4, screw mandrel 2, the and of gear-box 3
Motor 4 is connected respectively on platform 1, is connected between gear-box 3 and motor 4 by connecting rod 8, drives gear-box 3 to pass by connecting rod 8
It is dynamic, then drive screw mandrel 2 to rotate, fixed block 5 and lower fixed block 7 are also threaded with described screw mandrel 2, upper fixed block 5
External screw thread connects with the screw-internal thread fit of lower fixed block 7；Threaded connection is additionally provided between described upper fixed block 5 and lower fixed block 7
Thin nut 6 on upper fixed block 5, thin nut 6 are resisted against on lower fixed block 7, are carried out between fixed block 5 and lower fixed block 7
Distance positioning, as needed, thin nut 6 is adjusted, fixed block 5 and lower fixed block 7, effectively prevent screw mandrel 2 in locking
Rock, extend service life.
Further, described screw mandrel 2, upper fixed block 5 and the lower coaxial inner conductor of fixed block 7, ensure that precision.
Further, the tank material of described gear-box 3 is the aluminum or aluminum alloy class material of lighter in weight, and load is light,
And it will not get rusty.
Further, described upper fixed block 5 is relative flat at least provided with one group with the external surface of lower fixed block 7
Face, it is convenient during for installing and change, without specific purpose tool, only need common spanner.
When this detent mechanism in use, upper fixed block 5, thin nut 6 and lower fixed block 7 to be fixed to the corresponding positions of screw mandrel 2
Put, and adjusted the distance between upper fixed block 5 and lower fixed block 7 with thin nut 6, and thin nut 6 is tightened against in lower fixation
On block 7, you can.
It is above preferred embodiment of the present utility model, the scope of protection of the utility model is not limited, for ability
The deformation and improvement that field technique personnel make according to mentality of designing of the present utility model, should all be considered as protection of the present utility model
Within the scope of.
