Description
Technical field
The present invention relates to physics teaching technical field more particularly to a kind of spark timers of adjustable paper tape width.
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, it is found that the limit hole size of existing instrument is fixed（As shown in Figure 4）, a kind of paper tape of specification can only be used, it can not
Using wider paper tape, the development of experiment will affect.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of adjustable paper tape width proposed
Spark timer.
To achieve the goals above, present invention employs following technical solutions：
A kind of spark timer of adjustable paper tape width, including spark timer ontology, the spark timer ontology
Top offer stepped groove, stair-stepping paper tape limiting device baffle, the paper tape limiting device baffle are equipped in the stepped groove
Top side offer the first strip-shaped hole, the top other side of the paper tape limiting device baffle offers the second strip-shaped hole, institute
It states and is equipped with lock-screw in the first strip-shaped hole, 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 beneficial effects of the invention are as follows：
The present invention is according to paper tape size, and mobile paper tape limiting device baffle, at this moment lock-screw can be fastened in the first strip-shaped hole
Different location adjusts very convenient, using flexible, production is simple, at low cost consequently facilitating placing different size of paper tape.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
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 foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
