Description
Technical field
The utility model is related to a kind of New type rubber eraser head mechanical pencils, belong to study article technical field.
Background technology
In our study, mechanical pencil can be all used, and after the rubber of mechanical pencil upper end has substantially been used several times, etc.
It can not just be used again after the rubber exposed is finished, and in fact it is known that there is one section of rubber in hollow bush
Skin is not efficiently used, furthermore, want that replacing rubber also seems pretty troublesome.Based on the above reason, it is necessary to be carried out to mechanical pencil
Certain improvement.
Invention content
The technical problems to be solved in the utility model is：The utility model provides a kind of New type rubber eraser head mechanical pencil, is used for
Solve the problems, such as that the rubber in the pipe sleeve of mechanical pencil top cannot make full use of and replace inconvenience.
Technical solutions of the utility model are：A kind of New type rubber eraser head mechanical pencil, including rubber 1, pen cap 2, hollow sleeve 3,
Draw core pipe 4, crust 5；Hollow sleeve 3 is managed interior all equipped with internal thread, is drawn 4 upper end of core pipe and is equipped with external screw thread；
The internal thread of 3 lower part of the hollow sleeve is connected with the external screw thread for drawing 4 upper end of core pipe；
The external thread length for drawing 4 upper end of core pipe should be less than the length of hollow sleeve 3；
The rubber 1 is embedded into the upper part of hollow sleeve 3；
The core pipe 4 of drawing is placed in crust 5, and pen cap 2 is stamped in 1 outside of rubber；
When 1 length of rubber length can be in use, crust 5 and pen cap 2 remove, rubber 1 is embedded into part on hollow sleeve 3, rubber
The length that skin 1 is embedded into hollow sleeve 3 is the half of total length, and 3 spiral of hollow sleeve is assembled into one on the top for drawing core pipe 4
A complete mechanical pencil uses, and when the rubber 1 exposed will be finished, crust 5 and pen cap 2 remove, 3 downward spiral shell of hollow sleeve
Rotation, makes rubber 1 expose and is continuing with.
The operation principle of the utility model is：
First mechanical pencil crust 5 and pen cap 2 are removed when in use, sizeable rubber 1 is embedded into hollow sleeve
The upper part of pipe 3, the lower half portion of hollow sleeve 3 by screw thread with draw 4 top of core pipe and coincide together with, be then then assembled into one
A entirety uses.After the rubber 1 of top half is finished, crust 5 and pen cap 2 are removed, it can be by downward by hollow sleeve 3
The mode of spiral will be exposed embedded in 1 part of rubber for hollow sleeve 3, is continuing with, waits having used up again one, spiral down
Point, until the rubber on mechanical pencil top can be fully utilized.
The utility model has the beneficial effects that：The rubber on the utility model mechanical pencil top can obtain profit to greatest extent
With, and it is simple and convenient, rubber is replaceable.
Description of the drawings

When Fig. 2 is that the utility model rubber is longer, the inside half-section diagram of rubber tip mechanical pencil top half；
When Fig. 3 is that the utility model rubber is shorter, the inside half-section diagram of rubber tip mechanical pencil top half；
When Fig. 4 is that the utility model rubber is shorter, the half-section diagram of rubber tip mechanical pencil top half.
Each label in Fig. 1-4：1- rubbers, 2- pen caps, 3- hollow sleeves, 4- draw core pipe, 5- crusts.
Specific implementation mode
Utility model will be further explained below with reference to the attached drawings and specific embodiments.
Embodiment 1：As shown in Figs 1-4, a kind of New type rubber eraser head mechanical pencil, including rubber 1, pen cap 2, hollow sleeve 3, draw
Core pipe 4, crust 5；Hollow sleeve 3 is managed interior all equipped with internal thread, is drawn 4 upper end of core pipe and is equipped with external screw thread；
The internal thread of 3 lower part of the hollow sleeve is connected with the external screw thread for drawing 4 upper end of core pipe；
The external thread length for drawing 4 upper end of core pipe should be less than the length of hollow sleeve 3；
The rubber 1 is embedded into the upper part of hollow sleeve 3；
The core pipe 4 of drawing is placed in crust 5, and pen cap 2 is stamped in 1 outside of rubber；
When 1 length of rubber length can be in use, crust 5 and pen cap 2 remove, rubber 1 is embedded into part on hollow sleeve 3, rubber
The length that skin 1 is embedded into hollow sleeve 3 is the half of total length, and 3 spiral of hollow sleeve is assembled into one on the top for drawing core pipe 4
A complete mechanical pencil uses, and when the rubber 1 exposed will be finished, crust 5 and pen cap 2 remove, 3 downward spiral shell of hollow sleeve
Rotation, makes rubber 1 expose and is continuing with.
The course of work of the utility model is：Most start, when rubber 1 is longer, the top semi-cutaway of rubber tip mechanical pencil
As shown in Figure 1, first removing crust 5 and pen cap 2, when rubber 1 is embedded into hollow sleeve 3, rubber 1 is embedded into hollow sleeve
3 length about should be the half of 1 total length of rubber, as shown in Fig. 2, then again by 3 spiral of hollow sleeve on the top for drawing core pipe 4
End is then assembled into a complete mechanical pencil and uses.It, will be outer when the rubber 1 that mechanical pencil is exposed will use up top half
Skin 5 and pen cap 2 remove, then by 3 downward spiral of hollow sleeve, the rubber exposed 1 are made to account for about the half of total length, such as Fig. 3 institutes
Show, then group loads onto crust 5 and pen cap 2 as shown in figure 4, then mechanical pencil can be continuing with rubber 1 again.Repeatedly, until
It is finished, then replaces rubber 1 again, repeat the above steps.
Specific embodiment of the utility model is explained in detail above in conjunction with attached drawing, but the utility model and unlimited
