Description
Technical field
This utility model is related to a kind of inertia experiment demonstration trolley, belongs to experiment appliance technical field.
Background technology
In existing physics educational apparatus, the fundamental property of inertia when only demonstration object is static, and lack demonstration object fortune
The teaching aid of inertia performance when dynamic, teacher can only draw in blackboard in explanation and explain, waste time and energy, and the not readily understood palm of student
Hold.
The measurement data in demonstration of inertia experiment demonstration trolley disclosed in Authorization Notice No. cn202887539u is inaccurate, and
And complex operation, lose time, inefficiency.
Utility model content
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of inertia experiment demonstration trolley.
A kind of inertia experiment demonstration trolley of the present utility model, it comprise dolly, draw ring, bracing frame, sleeve pipe, hitching frame,
Drawstring, experiment ball, ball-catching disc, absorption layer, horizontal scale, longitudinal scale；The installed in front of dolly has draw ring, the upper end peace of dolly
Equipped with bracing frame, the middle part of bracing frame upper end is provided with sleeve pipe, sleeve pipe be internally provided with experiment ball, experiment ball pass through drawstring with
Hitching frame connects, and hitching frame is arranged on bracing frame, and the inner side of bracing frame is provided with ball-catching disc, and the inner side of ball-catching disc is provided with suction
Attached pad, the rear side of ball-catching disc and left side are separately installed with horizontal scale, longitudinal scale.
Preferably, the upper surface of described absorption layer is provided with adhesive linkage.
Preferably, the outer surface socket wear-resistant sleeve of described draw ring.
The beneficial effects of the utility model are: the horizontal scale from ball-catching disc, longitudinal scale can read size, thus
Measurement data, simultaneously facilitates and does acceleration test, and measurement data is also accurate simultaneously, easy to use, easy and simple to handle.
Facilitate implementation quick demonstration and operation, and measurement data is accurately, easy and simple to handle, high working efficiency.
Brief description
For ease of explanation, this utility model is embodied as and accompanying drawing is described in detail by following.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of ball-catching disc in this utility model.
In figure: 1- dolly；2- draw ring；3- bracing frame；4- sleeve pipe；5- hitching frame；6- drawstring；7- tests ball；8- ball-catching disc；
9- absorption layer；The horizontal scale of 10-；11- longitudinal direction scale.
Specific embodiment
For making the purpose of this utility model, technical scheme and advantage of greater clarity, shown in accompanying drawing
Specific embodiment is describing this utility model.However, it should be understood that these descriptions are simply exemplary, and it is not intended to limit this reality
With new scope.Additionally, in the following description, eliminate the description to known features and technology, to avoid unnecessarily mixing
Confuse concept of the present utility model.
As shown in Figure 1-2, this specific embodiment employs the following technical solutions: it comprise dolly 1, draw ring 2, bracing frame 3,
Sleeve pipe 4, hitching frame 5, drawstring 6, experiment ball 7, ball-catching disc 8, absorption layer 9, horizontal scale 10, longitudinal scale 11；The front side of dolly 1
Draw ring 2 is installed, the upper end of dolly 1 is provided with bracing frame 3, and the middle part of bracing frame 3 upper end is provided with sleeve pipe 4, the inside of sleeve pipe 4
It is provided with experiment ball 7, experiment ball 7 is connected with hitching frame 5 by drawstring 6, and hitching frame 5 is arranged on bracing frame 3, bracing frame 3
Inner side is provided with ball-catching disc 8, and the inner side of ball-catching disc 8 is provided with absorption layer 9, and the rear side of ball-catching disc 8 and left side are separately installed with horizontal stroke
To scale 10, longitudinal scale 11.
Further, the upper surface of described absorption layer 9 is provided with adhesive linkage.
Further, the outer surface socket wear-resistant sleeve of described draw ring 2.
The operation principle of this specific embodiment is: by draw ring 2 connection stay cord, drawstring drives dolly 1 at the uniform velocity to be transported
Dynamic, when carrying out uniform motion, quick shearing drawstring, experiment ball 7 drops on the absorption layer 9 on ball-catching disc 8, from ball-catching disc 8
On horizontal scale 10, longitudinal scale 11 read size, thus measurement data, simultaneously facilitate and do acceleration test, measure simultaneously
Data is also accurate, easy to use, easy and simple to handle.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also
Have various changes and modifications, these changes and improvements both fall within the range of claimed this utility model.This utility model
Claimed scope is by appending claims and its equivalent thereof.
