Description
Technical field
The utility model is related to Physical Experiment equipment technical field, specially a kind of Physical Experiment pulley.
Background technology
Pulley is, through commonly used equipment, necessity to be especially even more in Experiments of Machanics in Physical Experiment, and pulley is in power
Learn in experiment, experimental data can be directly affected if the frictional force between pulley and pulley sleeve is excessive, pulley is by hook
After mounting, hook can pull pulley sleeve so that pulley sleeve middle part is expanded to both sides, can thus produce certain tension force to cause to slide
Frictional force increase between wheel and pulley sleeve, so as to influence experimental data.
Utility model content
The purpose of this utility model is to provide a kind of Physical Experiment pulley, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of Physical Experiment pulley, including cunning
Wheel, the fixed grafting axle two in pulley middle part, the axle two is plugged in the inside of bearing, and extends to outside pulley sleeve, described
Axle cap is welded at the two ends of axle two, and the bearing is embedded in the middle part of pulley sleeve, and the pulley sleeve top and bottom pass through axle one
Connection, is socketed with support bar on the axle one, hook, the pulley sleeve middle part also welding support are welded with the support bar
Plate, the supporting plate lower surface positioned at pulley sleeve top is hinged fixture block.
Preferably, the fixture block rotates 180 degree by hinge around supporting plate, and fixture block bottom is provided with groove, and quantity is
Two pieces.
Preferably, the supporting plate lower surface is arcuate structure.
Preferably, the support bar can automatically be rotated around axle one.
Compared with prior art, the beneficial effects of the utility model are：The utility model simple structure, by axle two and two
The axle cap at end can reduce the tension force in the middle part of pulley sleeve, so that reduce the frictional force of pulley, while supporting plate is combined with, and supporting plate
The tension force between pulley sleeve can also be reduced, it is possible to reduce the frictional force between pulley and pulley sleeve, the setting of fixture block can in case
In only testing, rope comes off from the gap of pulley, plays certain protective action.
Brief description of the drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure right view.
In figure：1 pulley sleeve, the hook of 2 axle one, 3,4 pulleys, 5 axle caps, 6 support bars, 7 supporting plates, 8 fixture blocks, 9 axles two, 10 axles
Hold.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of Physical Experiment pulley, including pulley 4,
The fixed grafting axle 29 in the middle part of the pulley 4, the axle 29 is plugged in the inside of bearing 10, and extends to outside pulley sleeve 1, institute
State the two ends of axle 29 and weld axle cap 5, the bearing 10 is embedded in the middle part of pulley sleeve 1, and the top and bottom of the pulley sleeve 1 are
Connected by axle 1, support bar 6 is socketed with the axle 1, the support bar 6 can automatically be rotated around axle 1, the branch
Hook 3 is welded with strut 6, supporting plate 7 is also welded at the middle part of the pulley sleeve 1, and the lower surface of the supporting plate 7 is arcuate structure,
The lower surface of supporting plate 7 positioned at the top of pulley sleeve 1 is hinged fixture block 8, and the fixture block 8 rotates 180 by hinge around supporting plate 7
Degree, and the bottom of fixture block 8 is provided with groove, quantity is two pieces.
In sum：The supporting plate 7 connected between pulley sleeve 1 can prevent from producing pulley sleeve both sides when suspension is linked up with
Tension force so that pulley coefficient of friction rises, and influences experimental data, while being welded between axle 29 and pulley 4, and two ends of axle 29
It is welded with axle cap 5 and is also possible to prevent the middle part of pulley sleeve 1 to both sides generation tension force, influence coefficient of friction, the two ends of axle 29 is plugged on axle
10 inside is held, the frictional force of pulley 4 can be reduced so that the data of experiment are more accurate.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out various changes in the case where principle of the present utility model and spirit is not departed from, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
