Abstract

The utility model relates to a chalk holder which comprises a holder cover (1) and a holder body (3) fixed with the holder cover (1), and further comprises a spring (2) and a buckle (4) which are sleeved on the holder body (3) tightly, wherein the spring (2) is fixed on the holder cover (1), the buckle (4) can move forwards and backwards on the outer wall of the holder body (3), and the holder body (3) is sectional. Due to adoption of the chalk holder with the structure, not only are hands kept clean, but also the length of chalks in the holder body can be adjusted, and a chalk cut off in the holder body is quickly taken out, so that the use function and practicality of the chalk holder are improved, and the chalk holder is suitable for various chalks.

Description

A kind of chalk sleeve

Technical field

The utility model relates to a kind of chalk sleeve, belongs to the realia field.

Background technology

Chalk, it is the indispensable instrument that coordinates blackboard writing, it has multiple color, use by different colours makes emphasis be distinguished, but because chalk is to consist of granular structure, make chalk easily occur that when writing dust or dust stick at finger, make the dirty and inconvenient touch of hand other places.In order to address this problem, people work out a kind of chalk sleeve with upper shield, can be by chalk sleeve in body, holding body just can avoid hand to contact with the direct of chalk, thereby kept the clean of hand, but this chalk sleeve is appointed some problems of right existence, while using this chalk sleeve, because body is the structure of sealing, when chalk sleeve needs to stretch out therein, be not easy to regulate the length of chalk in body, and because chalk is more fragile, when chalk breaks in body, the chalk broken can easily not taken out, thereby the continuation that affects chalk sleeve is used, make the practicality of chalk sleeve reduce.

Summary of the invention

Technical problem to be solved in the utility model is the defect for background technology, a kind of chalk sleeve is provided, by adopting the segmented body, and by spring and body outer wall close fit, latch closure moves forward and backward realizes opening or closure of body, thereby can regulate easily the length of chalk in body, and can take out efficiently card and break at the chalk of body inside.

The utility model is in order to solve the problems of the technologies described above by the following technical solutions:.

The utility model provides a kind of chalk sleeve, comprise upper shield and with the fixing body of upper shield, also comprise the spring and the latch closure that are tightly placed in the body outer wall, its medi-spring is fixed on cover and covers, latch closure moves forward and backward at the body outer wall, described body is the segmented body.

As a kind of optimal technical scheme of the present utility model: described body adopts the cylindrical structural that is divided into two sections.

As a kind of optimal technical scheme of the present utility model: the diameter of described upper shield is greater than the diameter of body.

As a kind of optimal technical scheme of the present utility model: described chalk sleeve adopts plastic material to make, and its length is in the 4-7 cm range.

The utility model adopts above technical scheme compared with prior art, has following technique effect:

(1) by adopting the segmented body, make body there is tension force, but and improve Zhang Du and tight ness rating by spring and body outer wall close fit, latch closure move forward and backward has realized body open or closed, strengthened the fastness of chalk in body simultaneously, thus can keep hands clean, can regulate again the length of chalk in body, take out efficiently card and break at the chalk of body inside, make the use function of chalk sleeve improve, strengthen practicality;

(2) body adopts the cylindrical structural that is divided into two sections, adopts this structure, makes cover physical efficiency and spring close fit, and the stationarity that makes body be connected to upper shield is stablized, and conveniently holds, and improves the comfort level of holding;

(3) diameter of upper shield is greater than the diameter of body, adopts this structure, can prevent that spring from skidding off body, increases the area that hand touches upper shield;

(4) chalk sleeve adopts plastic material to make, and its length, in the 4-7 cm range, adopts this structure, can alleviate the weight of chalk sleeve, make simultaneously chalk sleeve can by hand all or major part hold, be more suitable for using in the chalk of different length.

The accompanying drawing explanation

Fig. 1 is the structural representation of a kind of chalk sleeve closure of the utility model design.

Fig. 2 is the structural representation that a kind of chalk sleeve of the utility model design opens.

Fig. 3 is the structural representation that a kind of chalk sleeve of the utility model design is placed chalk.

Wherein label is explained: 1-upper shield, 2-spring, 3-body, 4-latch closure, 5-chalk.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As Fig. 1, shown in Fig. 2 and Fig. 3, the utility model has designed a kind of chalk sleeve, comprise upper shield 1 and with the fixing body 3 of upper shield 1, it is characterized in that: also comprise the spring 2 and the latch closure 4 that are tightly placed in body 3 outer walls, its medi-spring 2 is fixed on upper shield 1, and latch closure 4 moves forward and backward at body 3 outer walls, and described body 3 is the segmented body.

A kind of chalk sleeve of the utility model design, by adopting segmented body 3, make body 3 there is tension force, but and improve Zhang Du and tight ness rating by spring 2 and body 1 outer wall close fit, latch closure 4 moves forward and backward has realized opening or closure of body 1, strengthened the fastness of chalk in body 1 simultaneously, thereby can keep hands clean, can regulate again the length of chalk in body 1, taking out efficiently card breaks at the chalk of body 1 inside, make the use function of chalk sleeve improve, strengthen practicality.

As a kind of preferred embodiment of the present utility model: body 3 adopts the cylindrical structural that is divided into two sections, adopt this structure, make body 3 can with spring 2 close fit, the stationarity that makes body 3 be connected to upper shield 1 is stablized, and conveniently hold, improve the comfort level of holding.The diameter of upper shield 1 is greater than the diameter of body 3, adopts this structure, can prevent that spring 2 from skidding off body, increases the area that hand touches upper shield 1.Chalk sleeve adopts plastic material to make, and its length, in the 4-7 cm range, adopts this structure, can alleviate the weight of chalk sleeve, make simultaneously chalk sleeve can by hand all or major part hold, be more suitable for using in the chalk of different length.

A kind of chalk sleeve of the utility model design, in the middle of actual application, first moves latch closure 4 to upper shield 1 direction, Compress Spring 2, make body 3 open, by chalk 5 put into body 3 interior after, mobile latch closure 4 until chalk 5 firmly be fixed in body 3.When needs are regulated the length of chalk 5, mobile latch closure 4 slowly, by body 3, open in various degree, control chalk 5 to exposing, when chalk 5 cards break in body 3, latch closure 4 is moved to the beeline place of spring 2 compression, from the gap medium wave dynamic circuit breaker of the body 3 of segmented chalk 5, can realize adjusting and the taking-up process of the interior chalk 5 of body 3.Adopt the chalk sleeve of this structure, can keep hands clean, can regulate again the length of chalk in body, taking out efficiently card breaks at the chalk of body inside, make the use function of chalk sleeve improve, strengthen practicality, and can be matched with the use of various chalks.

The above is explained in detail embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken possessed those of ordinary skills, can also under the prerequisite that does not break away from the utility model aim, make a variety of changes.
