Abstract

The utility model relates to a chalk sleeve. The purpose is to solve the problem that a chalk damages hands, and has the advantages of hand protection and hand massage. The utility model is composed of a chalk, a locking nail, a handle, a massage pellet and a massage ball. The utility model is characterized in that the lower end of the chalk is directly arranged on the middle end of the handle, both sides of the upper end of the handle is screw connected with the front part of the locking nail, the root part of the massage pellet is pasted and arranged above the massage ball, and the root part of the massage ball is pasted and arranged above the handle. The utility model uses equipment of the daily service processing factory to produce in bulk so as to satisfy the requirement of the educational circles.

Description

Chalk sleeve

(1) technical field:

The utility model relates to chalk sleeve, divides the technical field of the clamper group that belongs to pencil or chalk by International Patent Classification (IPC) (IPC).

(2) background technology:

At present, the technology about the clamper group of pencil or chalk existing and that once had was all done very fruitful effort to the needs of chalk sleeve, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Li Guobin, Granted publication is that CN2222067Y China Patent No. (ZL) is: ZL95242994.2 number utility model patent title is the utility model patent of " locating chalk sleeve automatically ", the technical scheme that is adopted, technical elements in the clamper group of pencil or chalk is a routine of great value invention, and it has solved the technical problem that chalk sleeve can be located automatically effectively.But still have some deficits, it also is difficult to solve the chalk adversary injury, and the protection hand can be to the technical problem of hand massage.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of chalk sleeve.To solve the chalk adversary injury is arranged, the protection hand can be to the technical problem of hand massage.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: chalk sleeve of the present utility model mainly is made of chalk, locking nail, handle, massage grain, massage ball.

In shape, structure and combination thereof, the total essential features of chalk sleeve of the present utility model and immediate prior art is: chalk is installed in the upper end of handle, is combined into the bascule of the rectangular shape of projection, and function has been the effect of chalk sleeve.In shape, structure and combination thereof; the chalk sleeve of the present utility model technical characterictic different with immediate prior art is: the lower end of chalk is directly installed on the intermediate ends of handle; the both sides, upper end of handle are threaded in the front portion of locking nail; be combined into the removable structure of the rectangular shape of band projection, function has been the effect that can directly not take chalk hygienic protection hand.The root of massage grain paste be installed in massage ball above, the root of massage ball paste be installed in handle above, be combined into the fixed structure of the rectangular shape of band projection, function has been that the adversary plays massage.The chalk adversary who has so just reached chalk sleeve of the present utility model has injury, and the protection hand can be to the purpose of hand massage.

The beneficial effect of the chalk sleeve of utility model is that the utility model is to solve the chalk adversary injury is arranged; the protection hand, can compare two place's advantage and improvement with existing with the technology that once had to the technical scheme that technical problem adopted of hand massage about the clamper group of pencil or chalk:

First; because the lower end of having designed chalk in the technical scheme of chalk sleeve of the present utility model is directly installed on the intermediate ends of handle; the both sides, upper end of handle are threaded in the front portion of locking nail; be combined into the removable structure of the rectangular shape of band projection, so the technical problem of chalk hygienic protection hand can not directly be taken in easier solution.

Second, since designed in the technical scheme of chalk sleeve of the present utility model the root of massage grain paste be installed in massage ball above, the root of massage ball paste be installed in handle above, be combined into the fixed structure of the rectangular shape of band projection, so easier solution adversary plays the technical problem of massage.

(4) description of drawings:

Accompanying drawing provides the structural representation of chalk sleeve of the present utility model:

Fig. 1: the overall structure schematic diagram that is chalk sleeve of the present utility model;

The label declaration at each position in the schematic diagram:

1 chalk, 2 locking nails, 3 handles, 4 massage grains, 5 massage balls

(5) specific embodiment:

Below in conjunction with accompanying drawing, chalk sleeve of the present utility model there is injury for realize solving the chalk adversary, the protection hand, the optimal way of the technical scheme that can take to the technical problem of hand massage is described further:

Its static structure: see also accompanying drawing: as shown in the figure, chalk sleeve of the present utility model mainly is made of chalk 1, locking nail 2, handle 3, massage grain 4, massage ball 5.Its major part chalk 1, locking nail 2 are selected for use by market.Its handle 3 is rectangle like shapes, is material with plastics, through the thermoforming processing and manufacturing.Its massage grain 4 is semi-spherical shape, is material with the elastic caoutchouc, through the Mould Machining manufacturing.Its massage ball 5 is semi-spherical shape, is material with the elastic caoutchouc, through the Mould Machining manufacturing.

In shape, structure and combination thereof, the total essential features of chalk sleeve of the present utility model and immediate prior art is: chalk 1 is installed in the upper end of handle 3, is combined into the bascule of the rectangular shape of projection, and function has been the effect of chalk sleeve.In shape, structure and combination thereof; this the novel chalk sleeve technical characterictic different with immediate prior art of usefulness is: the lower end of chalk 1 is directly installed on the intermediate ends of handle 3; the both sides, upper end of handle 3 are threaded in the front portion of locking nail 2; be combined into the removable structure of the rectangular shape of band projection, function has been the effect that can directly not take chalk hygienic protection hand.The root of massage grain 4 paste be installed in massage ball 5 above, the root of massage ball 5 paste be installed in handle 3 above, be combined into the fixed structure of the rectangular shape of band projection, function has been that the adversary plays massage.

Below by using method, further set forth chalk sleeve dynamic structure relation of the present utility model: in use, when needs use chalk, according to theory of mechanics, at first hold handle 3, then pen is put on the blackboard, write then again, thereby finish the task of using chalk.

In use, when needs are installed chalk,, at first locking nail 2 is turned on, put into chalk 1 then, tighten locking nail 2 more then and make chalk 1 fixing, thereby finish the task that chalk is installed according to theory of mechanics.The chalk adversary who has so just realized chalk sleeve of the present utility model has injury, and the protection hand can be to the technical scheme of the technical problem of hand massage.

Realize that preferred plan of the present utility model is is material with plastics etc., utilize the basic equipment of daily processing factory, take small serial production,, so just can realize the practical value and the economic worth of chalk sleeve of the present utility model better with the demand of supply educational circles.
