Abstract
The utility model relates to the construction tools of construction project, it is proposed a kind of measurement rope quickly retracting device, its structure is welded by reinforcing bar, it include bull wheel, hand crank and hand-held rod, the bull wheel includes 2 circle wheels, cross-bar in circle wheel, become the mandrel of bull wheel axis across cross-bar, and uniformly distributed 4~8 inner arc support rods between 2 circle wheels, mandrel is connected in the middle part of inner arc support rod, the handled door shape hand-held rod in middle part is movably connected on bull wheel by the close end that the annulus at its both ends is socketed in mandrel, the shape hand crank end L is welded to connect in one end of mandrel.In use, first will the binding of measurement rope rolling end on bull wheel, bull wheel rotation is then driven by rotation hand crank, measurement rope rolling is wound on bull wheel to realize, has the characteristics that structure is simple, easy to carry and can will measurement rope rolling quickly retracting.
Description
Technical field
The utility model relates to the construction tool of construction project, especially a kind of measurement rope draw off gear.
Background technique
Measurement rope is indispensable a kind of using tool in construction site, and conventional use of measurement rope length degree is at tens meters
Within range, because of the frequency that it is used, inventing a kind of easy to carry and winding draw off gear just seems necessary.
Utility model content
The purpose of this utility model is to provide a kind of measurement rope quickly retracting device, users simple with structure
Just, laborsaving, the quick and easy to carry feature of folding and unfolding.
To achieve the above object, the technical solution of the utility model is.
A kind of measurement rope quickly retracting device, it includes bull wheel, hand crank and hand-held rod that structure is welded by reinforcing bar.
The bull wheel includes 2 crosses in 250~300mm, the straight circle wheel through being 100~200mm, circle wheel
4~8 uniformly distributed inner arc support rods, interior bar, the mandrel for becoming bull wheel axis across cross-bar and 2 circle wheels
The both ends and circle wheel welded connecting, middle part of arc support rod are connected to mandrel.
The both ends of the handled door shape hand-held rod in middle part have annulus, and hand-held rod is socketed in the proximal end of mandrel by annulus
Portion is movably connected on bull wheel, and the shape hand crank end L is welded to connect in one end of mandrel.
In use, first binding at measurement rope rolling end on bull wheel, bull wheel rotation is then driven by rotation hand crank,
Measurement rope rolling is wound on bull wheel to realize.
The utility model have the characteristics that structure it is simple, it is easy to carry and can will measure rope rolling quickly retracting.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
With specific embodiment, the utility model is described in further detail below.
With reference to Fig. 1, a kind of measurement rope quickly retracting device, it includes bull wheel 1, hand crank 2 that structure is welded by reinforcing bar
With hand-held rod 3.
The bull wheel 1 includes 2 cross-baves 13 taken turns at a distance of 250mm, straight warp for circle wheel 11, the circle of 100mm in 11, wears
Cross-bar 13 is crossed as 4 inner arc support rods 12 uniformly distributed between the mandrel 14 of bull wheel axis and 2 circle wheels 11；It is interior
11 welded connecting of both ends and circle wheel of arc support rod 12, middle part are connected to mandrel 14, and middle part has the door shape of handle 32 portable
The both ends of bar 3 have annulus 31, and hand-held rod 3 is movably connected on bull wheel 1, L by the close end that annulus 31 is socketed in mandrel 14
2 end of shape hand crank is welded to connect in one end of mandrel 14.
In use, first then it is hand to be passed through rotation on the inner arc support rod 12 of bull wheel for the binding of measurement rope rolling end
Measurement rope rolling is wound on bull wheel 1 by the rotation for driving bull wheel 12 to realize, is had easy to carry and is rolled up measurement
The function of rope quickly retracting.
