Description
Technical field
This utility model relates to a kind of mechanical type small-size jack, belongs to technical field of jacks.
Background technology
Need the staff of field work currently for some for, ratio is if desired for the machine maintenance repaired facility in the wild
Pincers worker, it is often necessary to lifting, move weight large parts, owing to field lacks crane gear, and large-scale jack is due to structure
Complexity, weight is relatively big, is unfavorable for that field is carried, therefore, in the urgent need to the jack of a kind of simple in construction that is easy to carry to adapt to
Field work.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that a kind of simple in construction is just
In the mechanical type small-size jack carried.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of mechanical type small-size jack, including
Rotational structure and load-carrying members, described rotational structure is threaded connection with load-carrying members, and rotational structure is relative to load-carrying members
Rotating with by weight jack-up, described rotational structure top is provided with the load-bearing ball for jack-up weight.
Further providing for the concrete structure of a kind of rotational structure, described rotational structure includes rotary shaft and handle, handle
Being inserted into the top of rotary shaft, the bottom of described rotary shaft is provided with external screw thread, described load-carrying members be provided with in rotary shaft
The female through hole of tool that external screw thread matches.
Further for being suitable to the use of various height, described mechanical type small-size jack also includes distance spacer,
The middle part of distance spacer is provided with the through hole for accommodating rotary shaft, and the bottom of load-carrying members is provided with step so that by load-carrying members
It is supported on distance spacer.
After have employed technique scheme, turning handle, drive rotary shaft to rotate relative to load-carrying members, so that rotating
Axle moves up, and then promotes weight to rise；This utility model can also be laterally disposed, for moving heavy object；This utility model
Distance spacer for adjusting the distance between load-bearing ball and weight so that the opereating specification of this jack meets actual need
Want；This utility model simple in construction, manufacture method is simple, and lifting capacity is changeable, can be widely used in flight-line maintenance work.
Accompanying drawing explanation
Fig. 1 is front sectional view of the present utility model；
In figure, 1, load-bearing ball, 2, rotary shaft, 3, load-carrying members, 4, distance spacer, 5, handle.
Detailed description of the invention
In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail this utility model.
As it is shown in figure 1, a kind of mechanical type small-size jack, including rotational structure and load-carrying members 3, described rotational structure with
Load-carrying members 3 are threaded connection, and rotational structure rotates relative to load-carrying members 3 with by weight jack-up, described rotational structure top
End is provided with the load-bearing ball 1 for jack-up weight.
Preferably, as it is shown in figure 1, rotational structure includes rotary shaft 2 and handle 5, handle 5 is inserted into the top of rotary shaft 2,
The bottom of rotary shaft 2 is provided with external screw thread, and load-carrying members 3 are provided with has female thread with the external screw thread in rotary shaft 2 matches
Through hole.
Further, in order in the wild from making this jack, selection bolt is as rotary shaft 2, in the top of bolt is bored
Intention, load-bearing ball 1 is installed in rotation in above-mentioned central eye, and a horizontal through hole is bored on the top of bolt, is used for installing
Handle 5；
Selecting nut as load-carrying members 3, the internal thread hole of nut has externally threaded stud and coordinates with bolt, bolt phase
For nut rotation, thus the rotation of bolt is converted into the movement of the in the vertical direction of bolt, makes load-bearing ball 1 by weight
Jack-up.
Rotational structure is connected with load-carrying members 3 by this utility model by screw thread so that rotational structure can rest on and hold
The optional position of weight structure 3, without optional equipment latch-up structure, the mode of this self-locking more can meet the need of field work
Ask.
Preferably, as it is shown in figure 1, mechanical type small-size jack also includes distance spacer 4, the middle part of distance spacer 4
Being provided with the through hole for accommodating rotary shaft 2, the bottom of load-carrying members 3 is provided with step load-carrying members 3 to be supported on distance and adjusting
On joint pad 4.
Further, for the ease of field operation, distance spacer 4 can be chosen with the pipe fitting of appropriate length, at nut
Outside car goes out a step, by nut support on above-mentioned pipe fitting, changes the length of pipe fitting, it is thus possible to easily adjust this jack
And the distance between weight；Load-bearing ball 1 and nut are lubricated, in order to profit lifting.During real work, typically several are very heavy
Top supports the use.
Turning handle 5, drives rotary shaft 2 to rotate relative to load-carrying members 3, so that rotary shaft 2 moves up, and then pushes away
Dynamic weight rises；This utility model can also be laterally disposed, for moving heavy object；Distance spacer 4 of the present utility model is used for
Adjust the distance between load-bearing ball 1 and weight, be actually needed so that the opereating specification of this jack meets；This utility model is tied
Structure is simple, and manufacture method is simple, and lifting capacity is changeable, can be widely used in flight-line maintenance work.
Particular embodiments described above, solves the technical problem that this utility model, technical scheme and beneficial effect enter
Go further description, it should be understood that and the foregoing is only specific embodiment of the utility model, and need not
In limiting this utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement done
Deng, within should be included in protection domain of the present utility model.
