Description
Technical field
The utility model relates to physics teaching technical field more particularly to a kind of electric spark timing of adjustable paper tape width
Device.
Background technique
In the study required chapter 1 of high school physics, there is the content " with dotted timer degree of testing the speed ", in use process
In, find existing instrument limit hole size be it is fixed (as shown in Figure 4), can only use a kind of specification paper tape, can not
Using wider paper tape, the development of experiment will affect.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of adjustable paper tape proposed is wide
Narrow spark timer.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of spark timer of adjustable paper tape width, including spark timer ontology, the spark timer
Stepped groove is offered at the top of ontology, is equipped with stair-stepping paper tape limiting device baffle, the paper tape limiting device in the stepped groove
The top side of baffle offers the first strip-shaped hole, and the top other side of the paper tape limiting device baffle offers the second bar shaped
Hole, first strip-shaped hole is interior to be equipped with lock-screw, and movable sleeve is connected to gasket on the lock-screw, and the lock-screw passes through
First strip-shaped hole and be connected through a screw thread at the top of spark timer ontology.
Preferably, the width of the gasket is greater than the width of the first strip-shaped hole.
Compared with prior art, the utility model has the beneficial effects that
The utility model is according to paper tape size, and mobile paper tape limiting device baffle, at this moment lock-screw can be fastened on first
Different location on shape hole adjusts very convenient, using flexible consequently facilitating placing different size of paper tape, and production is simple, at
This is low.

Fig. 1 be the utility model proposes a kind of adjustable paper tape width spark timer top view；
Fig. 2 be the utility model proposes a kind of adjustable paper tape width spark timer side view；
Fig. 3 be the utility model proposes a kind of adjustable paper tape width spark timer paper tape limiting device baffle
Structural schematic diagram；
Fig. 4 is the top view of existing spark timer.
In figure: 1 spark timer ontology, 2 paper tape limiting device baffles, 3 lock-screws, 4 first strip-shaped holes, 5 gaskets, 6
Second strip-shaped hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-4, a kind of spark timer of adjustable paper tape width, including spark timer ontology 1, electric spark
The top of timer ontology 1 offers stepped groove, is equipped with stair-stepping paper tape limiting device baffle 2, paper tape limiting device in stepped groove
The top side of baffle 2 offers the first strip-shaped hole 4, and the top other side of paper tape limiting device baffle 2 offers the second strip-shaped hole
6, lock-screw 3 is equipped in the first strip-shaped hole 4, and movable sleeve is connected to gasket 5 on lock-screw 3, and lock-screw 3 passes through the first bar shaped
Hole 4 is simultaneously connected through a screw thread with the top of spark timer ontology 1.
The width of gasket 5 is greater than the width of the first strip-shaped hole 4.
Working principle: when operation, according to paper tape size, mobile paper tape limiting device baffle 2, at this moment lock-screw 3 can be fastened
Different location in the first strip-shaped hole 4 adjusts very convenient, using flexible consequently facilitating placing different size of paper tape, will
Paper tape is placed on paper tape limiting device baffle 2, and paper tape can open power supply after placing and be operated, if paper tape is wider,
It can first beat side, then reverse place into instrument and beat again.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
