Abstract

The utility model relates to a pencil lead box. The utility model is provided with an inner box body 1 and an outer box body 2 which is used for containing the inner box body. The front wall of the inner box body 1 is provided with a dial button which is embedded in a straight flute on the front wall of the outer box body. The utility model is characterized in that the right-side end of a movable box cover is movably connected with the outer box body by a rotary shaft 4. The bottom of the movable box cover 3 is also connected with an elastic clip base 7. Both sides at the upper end of the inner box body are also provided with square convex granules 8. The square convex granules 8 are correspondingly embedded in central-open square holes of the elastic clip base 7 at the bottom of the movable box cover 3. Users can control the dial button to make the inner box body move up and down by hands. The movable box cover completes on-off action through the functions of the square convex granules, the elastic clip base and the rotary shaft. The pencil lead box overcomes the defects of large on-off friction force and easy looseness of the box cover when the pencil lead box is opened.

Description

Pencil lead holder

[technical field]

The utility model relates to a kind of device that stores pencil-lead, is applicable to the storage pencil-lead.

[background technology]

Common a kind of pencil lead holder on the market, its lid structure has adopted incorgruous groove opening ways, that is: and this pencil lead holder has plate after the flute profile, and whole box body is embedded in the inner chamber of plate after the flute profile, only exposes the front panel of box body; The inner chamber of box body is the space that stores pencil-lead, and the block that install at box body upper opening place is the block of single page or pair of pages, controls the switching of pencil lead holder with the location of the vertical groove on plate top after the flute profile and oblique groove.Its shortcoming is, the friction force the during switching of pencil lead holder is bigger.Adopt the draw bail of simple rotating shaft as lid and box body, lid is loosening easily again when opening pencil lead holder.

[summary of the invention]

The purpose of this utility model is to provide a kind of pencil lead holder, and this pencil lead holder has overcome the friction force defective big, that lid becomes flexible easily when opening pencil lead holder when opening and closing.

The technical solution of the utility model is to consider like this: this pencil lead holder includes the inner box that is used to store pencil-lead, the outter box that is used to hold inner box, and movable lid, described inner box and outter box are bearing fit; The antetheca of described inner box is provided with toggle, is embedded in the straight trough of outter box antetheca; It is characterized in that: the right-hand end of the described movable lid of a. connects with the rotating shaft work is movable with outter box; The bottom of movable lid also is connected with the elasticity holder.B. the upper side of described inner box also is provided with square protruding grain, and described square protruding grain correspondence is embedded in the central opening square hole of movable lid bottom elasticity holder.

Pencil lead holder of the present utility model when opening, upwards promotes the toggle that is provided with on the inner box antetheca with hand, inner box moves up thereupon, and the square protruding grain that its side is provided with is by the elasticity holder, and promotion activity lid upwards, thereby open the lid, expose the lead for retractable pencil outlet.Otherwise, promoting toggle downwards with hand, inner box moves down thereupon, and lid closes up closure gradually.When carrying out the closure or openness operation, friction is very little; In addition, because the Clamping force of the protruding grain of elasticity holder square shaped after lid is opened, is not easy to become flexible.The defective that the friction force when thereby the pencil lead holder that has overcome prior art opens and closes is big, skid when opening pencil lead holder easily.

[specific embodiment]

Below in conjunction with accompanying drawing the utility model is narrated.As can be seen from Figure 1, this pencil lead holder contains the inner box 1 that is useful on the storage pencil-lead, the outter box 2 that is used to hold inner box, movable lid 3.Described inner box 1 is a bearing fit with outter box 2; The antetheca of described inner box 1 is provided with toggle 5, is embedded in the straight trough 6 of outter box 2 antethecas.The right-hand end of described movable lid 3 connects with outter box 2 usefulness rotating shafts 4 works are movable; The bottom of movable lid 3 also is connected with elasticity holder 7; The upper side of described inner box 1 also is provided with square protruding grain 8, and described square protruding grain 8 correspondences are embedded in the central opening square hole 9 of movable lid 3 bottom elasticity holders 7.

Structural representation when Fig. 2 is the pencil lead holder unlatching.Upwards promote the toggle 5 that is provided with on inner box 1 antetheca with hand, inner box 1 moves up thereupon, and the square protruding grain 8 that its side is provided with is by elasticity holder 7, promotion activity lid 3 upwards, thereby open the lid, expose the lead for retractable pencil outlet.Otherwise, promoting toggle downwards with hand, it is closed downwards that inner box drives lid.Because the Clamping force of the protruding grain 8 of elasticity holder 7 square shaped after lid 3 is opened, is not easy to become flexible.

Fig. 3 is the signal enlarged drawing that square protruding grain cooperates with the elasticity holder.In order to increase the elasticity of elasticity holder, the lid that has the elasticity holder is used the good plastic production of elastic force.

In order further to increase the reliability that pencil lead holder opens and closes, the two bottom sides of described movable lid 3 can be provided with two elasticity holders 7; Accordingly, the both sides, upper end of described inner box 1 also are provided with two square protruding grains 8, and described two square protruding grains 8 are corresponding respectively to be embedded in the central opening square hole 9 of two elasticity holders 7 of movable lid 3 two bottom sides.
