Description

The multifunctional chalk cover

Technical field:

The utility model is to belong to teaching aid, relates to the improvement of chalk sleeve structure.

Background technology:

When instructors was write writing on the blackboard on class, because hand closely contacts with chalk, the time had been grown and can the skin of hand have been caused damage; In order to solve such problem, people have designed chalk sleeve, and the application of chalk sleeve brings very big help for teachers, and the skin to protection teachers hand has played extraordinary effect; But existing chalk sleeve function singleness can not satisfy the use needs of instructors; For example: when using the chalk writing board book, chalk can not be good in chalk sleeve flexible, and the teacher gives a lesson to students at school the time diligently, the time of forgetting does not sometimes have prompting function, can not well be teacher's service, make troubles for the use of instructors.

The utility model content:

The utility model is exactly at the problems referred to above, provide a kind of capable of expansion and contraction, have timing function, a multifunctional chalk cover simple in structure.

In order to realize above-mentioned purpose, the utility model adopts following technical scheme, the utility model comprises that body is connected with base, body is the hollow circuit cylinder body structure, and the cylindrical body of its structural feature top is provided with the resistance support, and the resistance support is provided with spring clip, the body inner upper end is provided with supporting plate and is connected with spring, spring and strut fixation are provided with timer in the body bottom in the lower end of body, and cover external surface lower end is provided with timer key and vibrator are set.

The beneficial effects of the utility model:

1, capable of expansion and contraction:

Because bottom of the present utility model is provided with expansion link, be provided with the elastic force function at the two ends of a flexible intralamellar part, so along with the resistance support is touched in the use of chalk, chalk ejects the more effective instructors service that is very easily.

2, timing function:

Because cylindrical shroud body side surface of the present utility model is provided with timer, timer also has 0-99 minute timing function, can satisfy the course time set of primary school fully to university, so instructors can be regulated timing according to the time of a class, and timing prompting function of the present utility model timer also different from the past, timer on the contrary can be that the prompting of the timing means that adopted of music tip sound the utility model is that vibration prompt can not influence the notice that students is listened to the teacher between countdown in the past.

3, simple in structure:

The utility model member is few, and simple and convenient, is easy to make, and is easy to popularize.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

1 body, 2 supporting plates, 3 springs, 4 bases, 5 poles, 6 resistance supports, 7 timers, 8 spring clips, 9 vibrators, 10 timers are provided with key.

The specific embodiment:

The utility model comprises that body 1 is connected with base 4, body 1 is the hollow circuit cylinder body structure, body 1 top is provided with resistance support 6, resistance support 6 is provided with spring clip 8, body 1 inner upper end is provided with supporting plate 2 and is connected with spring 3, spring 3 is fixed on body 1 bottom with pole 5, is provided with timer 7 in the lower end of body 1, and body 1 outer surface lower end is provided with timer key 10 and vibrator 9 are set.

The middle part is provided with base 4 in the body 1, and the two ends of base 4 respectively are provided with two fixing points, are respectively applied for to fix two poles 5.

Be provided with timer 7 in the bottom of body 1, timer 7 has 0-99 minute countdown timing function.

Be provided with two timers below the timer 7 the time adjustment that 10, one on key is used for timer 7 is set, another is used for the adjustment of branch.

Inside, body 1 lower end is provided with vibrator 11, and vibrator 11 mainly is to be main element by an off-centre operation is arranged.

Below in conjunction with a description of drawings course of action of the present utility model:

The rigid body of rod of spring clip 8 usefulness is strutted, chalk is put on the supporting plate 2 of body 1, select to put into length according to the length of chalk, supporting plate 2 lower ends are connected with spring 3, and supporting plate 2 is pressed in the body 1 under the elastic force of spring 3, decontrol the spring clip 8 at top then, chalk just is fixed in the body 1.Can 10 pairs of timers 7 of key be set by timer is provided with, by timer be provided with key 10 the time adjust key to hour regulating, by timer the branch setting of the branch adjustment of key 10 to timer 7 is set again, just can carries out countdown behind timer 7 time sets.

Be with being appreciated that, more than about specific descriptions of the present utility model, only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
