Abstract
Disclosed is a multi-functional chalk cap, belonging to technique fields such as: Performance Operations; Transportation section, Printing sub-section, Writing or Drawing Implements; Bureau Accessories class, Implements for Writing or Drawing sub-class, Holders or connectors for writing implements; Means for protecting the writing-points group, and with means for preventing rolling sub-group, according to International Patent Classification (IPC). The purpose of the utility model is to solve the technical problems of skin injury when contacting the chalk by hand, and the utility model is mainly composed of a chalk, a sleeve, an inner thread, a screw plug and a rotary rod. The utility model is characterized in that: the screw plug thread is arranged in the inside of the inner thread, the rotary rod thread is mounted at the lower end position of the screw plug, which are suitable for the new technique proposal in the fields of Holders or connectors for writing implements; Means for protecting the writing-points group, and with means for preventing rolling sub-group, the utility model has broad purposes, and is easy to make with low cost, convenient using and easy promotion.
Description
(1) technical field:
The utility model relates to the multifunctional chalk cover, divides by International Patent Classification (IPC) (IPC) to belong to operation Department of Transportation, and printing branch is write or drawing appliance; The big class of office appliance is write or the drawing appliance group clamper of pencil or chalk; The pencil connector; Big group of the protector of reservoir tip has the technical field that prevents the device group that rotates.
(2) background technology:
At present, existing and once had about having the technology that prevents the device that rotates the demand of multifunctional chalk cover was all done very fruitful effort, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Liu Jianchun, Granted publication number is CN2234359Y, China Patent No. (ZL) is: No. 95241682.4 utility model title is the utility model patent of " a kind of pencil combined type extension element ", the technical scheme that is adopted.Having aspect the device technique that prevents to rotate is a routine of great value invention, and it has solved the technical problem of pencil with extension element effectively.But still have some deficits, it also is difficult to solve hand and touches chalk, the technical problem of injury skin.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of multifunctional chalk cover.Touch chalk to solve hand, the technical problem of injury skin.
The multifunctional chalk cover that the new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that this utility model mainly by: chalk, pen cap tube, internal thread, vice, swingle constitute.Its chalk is by selecting for use on the market.Its pen cap tube is a drum, is material with plastics, and process is moulded, the tapping processing and manufacturing.Its internal thread is spiral-shaped, is material with plastics, through the tapping processing and manufacturing.Its vice is spiral-shaped, is material with plastics, through moulding processing and manufacturing.Its swingle is a circular bar shape, is material with plastics, through moulding processing and manufacturing.
In shape, structure and combination thereof, multifunctional chalk cover of the present utility model with the essential features that immediate prior art has is: chalk contacts the inner wall position that is installed in internal thread, be combined into the conjuncted structure of cylindrical shape, function has been a fixation.In shape, structure and combination thereof, the multifunctional chalk cover of the present utility model technical characterictic different with immediate prior art is: the vice screw thread is installed in the interior position of body of internal thread, is combined into the conjuncted structure of cylindrical shape, and function is the lifting effect.The swingle screw thread is installed in the lower end position of vice, is combined into the conjuncted structure of T-shaped shape, and function is to play rotating action.The solution hand of so just having realized multifunctional chalk cover of the present utility model touches chalk, the purpose of the technical problem of injury skin.
The beneficial effect of the multifunctional chalk cover of utility model is: the utility model touches chalk for solving hand, the technical scheme that technical problem adopted and the clamper about pencil or chalk existing and that once had of injury skin; The pencil connector; Big group of the protector of reservoir tip has the technology that prevents the device group that rotates and has compared two advantages and improvement:
The first, owing to designed position in the body that the vice screw thread is installed in internal thread in the technical scheme of multifunctional chalk of the present utility model cover, be combined into the conjuncted structure of cylindrical shape, so technical problem that can easier solution lifting.
The second, owing to designed the lower end position that the swingle screw thread is installed in vice in the technical scheme of multifunctional chalk of the present utility model cover, be combined into the conjuncted structure of T-shaped shape, so technical problem that can easier solution rotation.
(4) description of drawings:
Accompanying drawing provides the structural representation of multifunctional chalk cover of the present utility model:
Fig. 1: the main TV structure schematic diagram that is multifunctional chalk cover of the present utility model:
The label declaration of parts in the schematic diagram:
1 chalk, 2 pen cap tubes, 3 internal threads, 4 vices, 5 swingles
(5) specific embodiment:
Below in conjunction with accompanying drawing, for realizing that solving hand touches chalk, the optimal way of the technical scheme that the technical problem of injury skin is taked is described further to multifunctional chalk cover of the present utility model:
Its static structure: please join accompanying drawing: as shown in the figure, multifunctional chalk cover of the present utility model is mainly by chalk 1, and pen cap tube 2, internal thread 3, vice 4, swingle 5 constitute.Its chalk 1 is by selecting for use on the market.Its pen cap tube 2 is drums, is material with plastics, and process is moulded, the tapping processing and manufacturing.Its internal thread 3 is spiral-shaped, is material with plastics, through the tapping processing and manufacturing.Its vice 4 is spiral-shaped, is material with plastics, through moulding processing and manufacturing.Its swingle 5 is circular bar shape, is material with plastics, through moulding processing and manufacturing.
In shape, structure and combination thereof, multifunctional chalk cover of the present utility model with the essential features that immediate prior art has is: chalk 1 contacts the inner wall position that is installed in internal thread 3, be combined into the conjuncted structure of cylindrical shape, function has been a fixation.In shape, structure and combination thereof, the multifunctional chalk cover of the present utility model technical characterictic different with immediate prior art is: vice 4 screw threads are installed in the interior position of body of internal thread 3, be combined into the conjuncted structure of cylindrical shape, function is the lifting effect.Swingle 5 screw threads are installed in the lower end position of vice 4, are combined into the conjuncted structure of T-shaped shape, and function is to play rotating action.
Below by using method, further set forth the dynamic structure relation of this practical multifunctional chalk cover: in use, when rotating swingle, chalk 1 stretches out the pen cap.According to spiral principle, its chalk 1 acts on internal thread 3 by vice 4, thereby finishes the task of lifting.
In use, in the time of not lifting, can remove swingle 5 from vice 4 and put well, thereby finish the task of not lifting.The solution hand of so just having realized multifunctional chalk cover of the present utility model touches chalk, the purpose of the technical problem of injury skin.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of plastics factory, take to produce by batch in batches, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
