Abstract
The invention discloses a chalk cover with a laser lamp. The chalk cover is mainly composed of an outer cover shell (1) and an inner cover shell (2). An inner thread is arranged on the inner side wall of the outer cover shell (1), and an outer thread is arranged on the outer side wall of the inner cover shell (2). The outer cover shell (1) and the inner cover shell (2) are in threaded connection, and the inner cover shell (2) rotates to ascend and descend in the outer cover shell (1), and the lifting distance is 10 cm. An arc inverted-T-shaped elastic sheet (3) is arranged on the inner side wall of the inner cover shell (2). A laser assembly is further arranged at the bottom of the outer cover shell (1) and comprises a lithium battery (5), the laser lamp (6) and a switch button (7), wherein the switch button (7) is connected to an electrification loop of the lithium battery (5) and the laser lamp (6) in series and is arranged on the outer surface of the outer cover shell (1) in a protruding manner. The chalk cover is simple in structure and convenient to use, the finger does not need to make direct contact with chalk when the chalk is used for writing, the chalk is not prone to fracture in the writing process, and the laser irradiation and indication functions are achieved.
Description
Technical field
The invention belongs to culture and education fixture fields, be specifically related to the chalk of a kind of band laser lamp for encapsulation chalk
Set.
Background technology
Chalk in use there is problems in that one is directly to pinch chalk to use with hands, and chalk can stick to your hands,
Need to clean and more bother；Two is that when in use exerting oneself excessive, chalk also frangibility causes waste, and three is that chalk uses
After a period of time shortens, remaining chalk end often due to bad pinching and be thrown away, cause waste.
It is, thus, sought for one is in use, it is not necessary to directly pinch chalk, chalk is not easy to fracture and energy
Enough ways effectively shortening the chalk end length being thrown away.
It addition, teacher is saying class hour, in order to improve teaching efficiency, often go down dais, go in student and explain
Knowledge.When explanation on needs comparison blackboard, if the knowledge content on blackboard is too much, student can not the most just find sometimes
Relevant knowledge point, have impact on the learning efficiency.
Summary of the invention
Present invention aims to the problem that prior art exists, it is provided that a kind of simple in construction, easy to use, energy
Enough need not when using chalk-writing that finger directly contacts chalk, chalk is not easy to fracture and has radium in writing process
Shot-light irradiates the chalk sleeve of function.
To achieve these goals, present invention employs techniques below scheme:
The chalk sleeve of a kind of band laser lamp, is mainly made up of outer shell and interior sheath body；The medial wall of described outer shell sets
Female thread, the lateral wall of interior sheath body is had to be provided with external screw thread；Described outer shell and interior sheath body is threaded and interior sheath body outside
Sheath body internal rotating lifts, and lifting distance is 10cm；The medial wall of described interior sheath body is provided with curved convex shell fragment；Outside
The bottom of sheath body is additionally provided with laser module；Described laser module includes lithium battery, laser lamp and shift knob；Described
Shift knob is connected on the power circuit of lithium battery and laser lamp, and the prominent outer surface being arranged on outer shell.
In the present invention, in embedding the one of chalk in sheath body, the convex shell fragment in interior sheath body can clamp chalk, then
Rotate chalk, make interior sheath body decline, reserve the chalk of appropriate length.The adjustable height of 10cm, goes for current city
Most of chalk length on field.
The present invention further illustrates, and the outer surface of described outer shell is provided with cushion course.Set up cushion course, mainly allow and hold
The finger holding outer shell is more comfortable.
The present invention further illustrates, described convex shell fragment be provided with more than 2 and on interior sheath body medial wall circumferentially
Well-balanced layout.
The present invention further illustrates, and described outer shell and interior sheath body are aluminum matter pipe or irony pipe.Use metal material
The chalk sleeve made is more durable, and screw thread is not easy to abrasion.
Advantages of the present invention:
Simple in construction, reasonable in design, easy to use, will insert in interior sheath body respectively, the length that then regulation chalk reserves,
In use, finger gripping, on chalk sleeve, will not directly contact with chalk, hands of will not making dirty, and chalk is contained in chalk sleeve,
The most just it is not likely to produce and fractures.It addition, be additionally arranged at the bottom of laser module at chalk sleeve, facilitate teacher from blackboard farther out time, also can
Give student instruction, allow student quickly find corresponding knowledge point.
