Abstract
The utility model discloses a plastic and rubber automatic pencil rod which is the improvement of the structure of a full-automatic pencil. An automatically telescoping pencil spout is composed of a guard lead pipe and a damping element, and a pen head is sheathed outside of the exterior of the pencil spout, and the upper part is connected with screw threads and the pencil rod. The upper end of the damping element has a chuck sheathing. A chuck which is arranged in the chuck sheathing can freely move upward and downward. The chuck sheathing is mated with a chuck base. The upper end of the chuck tightly inserts the centre hole of the lower end of a lead transmission pipe. The upper end of the lead transmission pipe is an inner hole with the conicity which makes contact with a clamp lead sheet. The upper end of the clamp lead sheet inserts a lead storage library.
Description
The utility model relates to a kind of improvement of full automatic pencil structure, is a kind of rubber and plastic bar propelling pencil specifically.
General propelling pencil is in writing process, and lead for retractable pencil is easily loosening withdraws, and needs constantly to adjust, because inner other part concentricity is bad, easily lead is broken in the centre, and it is easily aging, of poor quality that plastics protect lead pipe, and the life-span is short, and changes the lead for retractable pencil trouble.Because the internal structure complexity, the packaging technology difficulty is bigger.
The utility model purpose is to overcome the shortcoming in the above-mentioned technology, and its structure is improved, and a kind of novel rubber and plastic bar propelling pencil is provided.Protecting lead pipe can stretch automatically, and the cassette lead for retractable pencil is flexible, and structure is simple relatively, makes easy to use.
Technical characterictic of the present utility model is as follows: the lead for retractable pencil (1) of rubber and plastic bar propelling pencil stretches out the centre bore that protects lead pipe (2), and the centre bore of damping piece (3) is enclosed within and protects lead pipe (2) top.Forming a flexible automatically pen chews, nib (4) is enclosed within its outside, nib (4) top and penholder (5) become the hand-held part of whole pen with being threaded, there is chuck sheath (6) upper end of damping piece (3), there are two holes two sides, penholder (4) upper end, tightly fasten with two projections of two sides, chuck sheath (6) upper end, chuck (7) can move by easy on and off in chuck sheath (6), chuck cover (8) is enclosed within chuck (7) exterior bottom, with chuck cover base (10) tight fit.Defeated lead pipe (11) lower end centre bore is tightly inserted in chuck (7) upper end, and the upper end of defeated lead pipe (11) is the endoporus of a Dai You Cone degree, contacts with card lead flake (13), in defeated lead pipe (11) centre bore lining (12) is arranged.Lead storage base (14) is inserted in card lead flake (13) upper end.
Lead storage base (14) is the drum shape, and as the base of rubber (15), the rubber upper end has a conduct to press the tail cap (16) of a usefulness, on penholder (5) outer wall penholder (18) is housed.Penholder is that the rubber-plastics material that adds fragrant agent is made, comfortable feel, and give out the fragrance of various odor types, as fruit flavouring, sandalwood type, lemon flavor etc.
A plastic bushing (12) is arranged in defeated lead pipe (11), concentric with defeated lead pipe (11), make with plastics, rubber one class material, play the protection lead for retractable pencil.
Card lead flake (13) is made up of two of mutual symmetry, the lower end band wing, insert in the lining (12) of defeated lead pipe (11), respectively there is the muscle sheet of a groove and a projection upper end, and working in coordination is set into an integral body, lead storage base (14) is inserted in card lead flake (13) upper end, plumbous Li Keda 150～300 grams of its withdrawing can be adorned many lead for retractable pencils in the lead storage base (14), and cassette lead for retractable pencil of whole composition partly.
Protecting the interior pore area in lead pipe (11) upper end has the Cone degree, and upper coarse and lower fine, its Cone degree is 7 °～9 °.
The shape of penholder (5) can be cylinder or multiedge cylinder, also can be the obform body that has various animal capitiforms, and various floral designs can also be arranged on penholder, and the penholder material is the magnetic rubber-plastic material, in hand-held part 2～3 anti-slip tanks is arranged.The graininess raw material of making penholder mix with neodymium, iron, boron powder, become permanent magnet through the mold pressing injection mo(u)lding, and this penholder has good stable magnetic.When holding, permanent magnetic field has magneticaction to finger section part, promotes partly blood microcirculation of finger, very beneficial to health, because hand-held partly anti-slip tank, make that to hold pen stable, can on penholder, not slide, have the rubber and plastic bar of fragrant taste, make comfortable feel when holding a pen.
The utility model has the advantages that because its penholder adopts the magnetic rubber-plastic material that contains aromatic to make, feel with fresh air when writing, comfortable feel when holding a pen; The permanent magnetism physical efficiency promotes the microcirculation of finger, improves health, and its structure is simple relatively, reliable, chuck (6) adopts copper material to make, and having adopted card lead flake double collet, automatic clamping chuck folder lead for retractable pencil power is bigger, adopts flexible automatically pen to chew in the writing process, can prevent that lead for retractable pencil from fractureing, can store many lead for retractable pencils in the storage lead pipe for using manufacturing relatively easy, easy to use, comfortable by root, be drawing, write that desirable writing implement charts.
Embodiment of accompanying drawings and operation principle thereof:
Accompanying drawing 1 is a rubber and plastic bar propelling pencil upper semisection structure chart;
Accompanying drawing 2 is a rubber and plastic bar propelling pencil lower semisection structure chart;
(1) lead for retractable pencil wherein, (2) protect lead pipe, (3) damping piece, (4) nib, (5) magnetic penholder, (6) chuck sheath, (7) chuck, (8) chuck cover, (9) spring, (10) chuck cover base, (11) fail lead pipe, (12) lining, (13) card lead flake, (14) lead storage base, (15) rubber, (16) tail cap, (17) penholder lining, (18) penholder.
Specification is that 05 millimeter lead for retractable pencil (1) is being write under the power effect, just have a responsive to axial force on the chuck (7) that copper product is made, simultaneously, the spring made from 10 millimeters of diameters, 1cr18Ni9Ti stainless steel (9) have one with write the power equal and opposite in direction, masterpiece that direction is opposite is used on the chuck (7) and will clamps lead for retractable pencil automatically, and lead for retractable pencil can not become flexible.
When with hand pressing tail cap (16), compressing lead storage base (14) is done mechanical movement downwards, push card lead flake (13) moves down at defeated lead pipe (11) the upper end endoporus that plastics are made, because of 7 °～9 ° of upper end endoporus De Cone degree, contact cooperation with card lead flake (13) flank, card lead flake (13) can be opened, by lining (12) output lead for retractable pencil (1).
When lead for retractable pencil (1) passes through copper chuck (7), as tail cap (16) the push card lead flake (13) of pressing a usefulness, promote defeated lead pipe (11) and act on copper chuck (7), copper chuck cover (8) is obstructed on chuck sheath (6), simultaneously also stop spring (9) to move on, chuck (7) external diameter is less than chuck cover (8) internal diameter, and the damping force of damping piece (3) drives lead for retractable pencil and exports a segment distance greater than the power output of lead for retractable pencil (1).In the writing process, the size of writing power constantly changes, and protects lead pipe (2) and constantly repeats to withdraw and reset, thereby constantly export the wearing and tearing of lead for retractable pencil with compensation writing process lead for retractable pencil, and flexible pen is chewed and can be prevented that lead for retractable pencil from fractureing automatically.
