Abstract
The invention relates to an automatic chalk sleeve, and relates to an automatic chalk sleeve. The automatic chalk sleeve comprises a housing in which a fixing sleeve with an upper end for clamping a chalk and a lower end in threaded connection with a screw is arranged; the automatic chalk sleeve is characterized in that a distance sensor is arranged at an opening of the housing, and the screw is mounted on a power control device connected with the distance sensor. The automatic chalk sleeve is provided with the distance sensor and the power control device so as to realize automatic regulation of the extension length of the chalk.
Description
Technical field
The present invention relates to a kind of chalk sleeve, particularly a kind of automation chalk sleeve.
Background technology
Chalk sleeve kind is in the market a lot, can protect well finger, is threaded connection the length that the mechanism of a class also can regulate chalk to stretch out simultaneously. But the mode of its manual adjustments wastes time and energy, in adjustment process, also inevitably want upper chalk dust in one's hands.
Summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of automation chalk sleeve.
The present invention is achieved through the following technical solutions:
A kind of automation chalk sleeve, comprise housing, in housing, be provided with the be threaded fixed cover of screw rod of clamping chalk lower end, upper end, it is characterized in that: the opening part of described housing is provided with range sensor, under described screw rod, fixed installation connects the power control unit of range sensor.
In described housing, be provided with guide groove, can prevent that fixed cover from circumferentially rotating.
Along with writing on blackboard, the chalk length that stretches out chalk sleeve can slowly shorten, that is the distance of chalk sleeve and seriticker shortens, in the time reaching certain value, range sensor can trigger power control unit and make bolt rotary, the reach of drive fixed cover, chalk is also along with more stretching out chalk sleeve opening.
The present invention is by arranging range sensor and power control unit, and the automation that has realized chalk extension elongation regulates.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing is structural representation of the present invention.
In figure, 1 housing, 2 guide grooves, 3 fixed covers, 4 screw rods, 5 power control units, 6 range sensors.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment comprises housing 1, in housing 1, be provided with the be threaded fixed cover 3 of screw rod 4 of clamping chalk lower end, upper end, it is characterized in that: the opening part of described housing is provided with range sensor 6,4 times fixed installations of described screw rod connect the power control unit 5 of range sensor 6.
In described housing 1, be provided with guide groove 2, can prevent that fixed cover 3 from circumferentially rotating.
