Summary of the invention
The purpose of this utility model is to provide a kind of lifting devices of freely adjustable carrier height, can arbitrarily adjust height
Degree, structure is simple, easy to operate.
The technical scheme adopted by the utility model is a kind of lifting device of freely adjustable carrier height, including bottom
, it is provided with a screw rod on the pedestal, tapped lifting platform is arranged on the screw rod, the lifting platform cooperates screw rod
On screw thread can move up and down, the locating part that can only move up and down of limitation lifting platform, the screw rod are additionally provided on the pedestal
Lower part is fixedly connected with first bevel gear, further includes the second bevel gear engaged with the first bevel gear, the second cone tooth
Wheel is fixedly connected with drive shaft.
Wherein, the locating part entangles lifting platform and is equipped with upright guide rail, the lifting platform edge inside the locating part
Upright guide rail moves up and down.
Wherein, the drive shaft other end is connected with motor or handle.
Wherein, the lifting platform is equipped with the top cover part of carrying carrier.
Wherein, the pedestal and the interconnecting piece of first bevel gear and second bevel gear are equipped with bearing.
Wherein, the pedestal is externally provided with base hood, and the base hood covers pedestal and drive shaft.
Compared with the prior art, the utility model has the following advantages: compared to the necessary both hands operation of traditional lifting, height
It is inconvenient to adjust, and operation difficulty is big, defect easy to damage；A kind of lifting of freely adjustable carrier height of the utility model fills
It sets, structure is simple, adds screw rod that elevating function can be realized by two gears, easily adjusts, and it is easy to operate, it goes up and down at any time.
Detailed description of the invention
Fig. 1 is the vertical section structure schematic diagram of the utility model.
Fig. 2 is the inside schematic perspective view of the utility model.
Figure label show 1- pedestal, 2- screw rod, 3- lifting platform, 4- locating part, 5- first bevel gear, 6- second and bores tooth

Specific embodiment:
For the understanding for deepening the utility model, the utility model is made below in conjunction with case study on implementation and attached drawing further detailed
It states.The utility model can be implemented in the following way:
A kind of lifting device of freely adjustable carrier height, including pedestal 1 are provided with a screw rod 2 on the pedestal 1,
Tapped lifting platform 3 is arranged on the screw rod 2, the lifting platform 3 is equipped with the top cover part 8 of carrying carrier.The liter
Drop platform 3 cooperates the screw thread on screw rod 2 can move up and down, and is additionally provided with what limitation lifting platform 3 can only move up and down on the pedestal 1
Locating part 4, the locating part 4 entangle lifting platform 3 and are equipped with upright guide rail 10,3 edge of lifting platform inside the locating part 4
Upright guide rail 10 moves up and down.2 lower part of screw rod is fixedly connected with first bevel gear 5, further includes and the first bevel gear 5
The second bevel gear 6 of engagement, the second bevel gear 6 are fixedly connected with drive shaft 7, the pedestal 1 and first bevel gear 5 and the
The interconnecting piece of two bevel gears 6 is equipped with bearing, and 7 other end of drive shaft is connected with motor or handle, and the pedestal 1 is externally provided with bottom
Seat cover 9, the base hood 9 cover pedestal 1 and drive shaft 7.
When it is implemented, manual turn drive shaft 7 rotates, when 7 one end of drive shaft when 7 other end of drive shaft is handle
When connecting motor, it can be driven by a motor the rotation of drive shaft 7, very convenient, the second bevel gear 6 in drive shaft 7 and then rotates,
And the first bevel gear 5 engaged with second bevel gear 6 is driven to rotate, the screw rod 2 being fixedly connected with first bevel gear 5 and then turns
Dynamic, the locating part 4 that the lifting platform 3 being threadedly engaged at this time with screw rod 2 is provided with upright guide rail 10 is limited in along 2 up and down direction of screw rod
Movement, and the top cover part 8 of carrying carrier is driven to realize lifting, due to being threadedly engaged for screw rod 2 and lifting platform 3, in gravity
Under, cooperation position has certain frictional force, therefore lifting platform 3 can rest within the scope of the arbitrary distance of run on screw rod 2, base hood
9 cover pedestal 1 and drive shaft 7, so that lifting device is not by external interference.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all wrap
Containing being within the protection scope of the utility model.
