Abstract
The utility model relates to an anti-fall pencil, comprising a pencil shell and a pencil lead arranged in the pencil shell, and further comprising an electromagnet, a spring, a button battery, an acceleration sensor and a controller, wherein the pencil lead is in sliding connection in the pencil shell; the upper end of the pencil lead is connected with the spring; the spring, the electromagnet, the controller, the acceleration sensor and the button battery are connected in sequence by wires; and an elastic material sleeve is sheathed at the outer surface of the pencil shell. In the anti-fall pencil, the structure is simple, and the acceleration sensor and the electromagnet are utilized to control the extension of the spring, so that when the pencil falls, the pencil lead can be retracted in the pencil shell in time; since the elastic material sleeve is sheathed outside the pencil shell, the purpose of good vibration reduction is achieved, and a pencil head and the pencil lead are prevented from being broken. The anti-fall pencil is convenient to use, and is especially suitable for being used by students.
Description
One, technical field
The utility model relates to a kind of anti-pencil that falls.
Two, background technology
The situation that pencil tumbles the ground takes place in regular meeting when using pencil, and the pencil-lead that at this moment not only tip of a pencil can be broken but also the pencil shell is interior also can be broken, and the obsolete phenomenon of pencil-lead can occur when therefore sharpening a pencil again, has wasted whole pencil.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, prevents the anti-pencil of breaking that falls.
The utility model solves the technical scheme that the prior art problem is adopted: a kind of resisting fallen pencil, comprises the pencil shell and is located at the interior pencil-lead of pencil shell, and it also comprises electromagnet, spring, button cell, acceleration transducer and controller; Described pencil-lead is slidingly connected in the pencil shell; Described pencil-lead upper end is connected with spring; Described spring, electromagnet, controller, acceleration transducer, button cell connect successively by lead; The outer surface of described pencil shell is with the elastomeric material cover.
Described elastomeric material cover is rubber sleeve.
The beneficial effects of the utility model are: the utility model is simple in structure, utilize the stretching of acceleration transducer and magnet control spring, make pencil pencil-lead when dropping to be retracted in the pencil shell timely thereby reach, because the pencil housing exterior is with the purpose that the elastomeric material cover has reached good damping, prevent the fracture of nib and pencil-lead, the utility model is easy to use, is particularly suitable for the student and uses.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment
Below in conjunction with specific embodiment the utility model is described:
As shown in Figure 1, a kind of resisting fallen pencil, comprises pencil shell 1 and the pencil-lead of being located in the pencil shell 12, and it also comprises electromagnet 3, spring 4, button cell 5, acceleration transducer 6 and controller 7; Pencil-lead 2 is slidingly connected in pencil shell 1; Pencil-lead 2 upper ends are connected with spring 4; Spring 4, electromagnet 3, controller 7, acceleration transducer 6, button cell 5 connect successively by lead; The outer surface of pencil shell 1 is with elastomeric material cover 8.Wherein preferred elastomeric material cover 8 is a rubber sleeve.
The course of work of the present utility model is as follows: when pencil falls down, acceleration transducer 6 is sensed acceleration and is promptly sent signal to controller 7, controller 7 is connected circuit makes electromagnet 3 produce magnetic, thereby attract spring 4 to shrink to electromagnet 3 ends, thereby pencil-lead 2 is contracted in the pencil shell 1, has protected pencil stub not broken; And can protect the pencil-lead 2 that puts in the pencil shell 1 by being enclosed within pencil shell 1 outer elastomeric material cover 8.
Above content be in conjunction with concrete optimal technical scheme to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
Claims (2)
1. one kind anti-is fallen pencil, comprises the pencil shell and is located at pencil-lead in the pencil shell, and it is characterized in that: it also comprises electromagnet, spring, button cell, acceleration transducer and controller; Described pencil-lead is slidingly connected in the pencil shell; Described pencil-lead upper end is connected with spring; Described spring, electromagnet, controller, acceleration transducer, button cell connect successively by lead; The outer surface of described pencil shell is with the elastomeric material cover.
