Detailed Description
In order to make the technical means of the present invention clearer and to implement the present invention according to the content of the specification, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples, which are used for illustrating the present invention and are not intended to limit the scope of the present invention.
The following embodiments describe in detail a pen structure for facilitating the removal of the cap of the pen. In the description, the direction in which the pen is in the writing state is taken as a reference direction.
The pen structure convenient for detaching the pen cap comprises a conventional pen holder 1 and a pen cap 2.
The pen barrel 1 is formed by integrally molding a pen barrel body 101, a matching section 102 connecting the pen barrel body and the end of the pen barrel, and a pen barrel end 103. The pen holder body 101 is a tubular structure with an opening at one end or two ends and is used for accommodating a pen core. If the penholder main body is provided with an opening at one end, the other end is in a sealed state; if the pen holder main body is provided with openings at two ends, the other end of the pen holder main body is in an open state, and the other end can be sealed by a sealing plug after the pen core is installed. The matching section 102 is formed by contracting radially inward from the bottom end of the pen holder main body and then continuing to extend axially downward, and the matching section directly extends on the pen holder main body and is mainly used for positioning a pen cap which is coaxially sleeved at the matching section. The pen holder end 103 is formed by contracting radially inward from the bottom end of the matching section and then continuing to extend axially downward, and is used for accommodating a pen point of a pen core, and the pen point penetrates out of the pen holder end.
A plurality of guiding ribs 3 arranged at intervals are formed on the outer peripheral wall of the matching section 102, and the plurality of guiding ribs are of spiral structures arranged along the same circumference. The length of the direction sand grip 3 of these a plurality of sections is unanimous and spiral angle is unanimous, and the top of a plurality of sections direction sand grip all is in on same circumference, then the bottom of these a plurality of sections direction sand grip also all is in on same circumference. In the embodiment, the guide convex strip 3 is provided with two sections, and the two sections of guide convex strips are respectively arranged at two opposite sides of the peripheral wall of the matching section 102 of the penholder; in addition, the radial cross section of each guide rib 3 in this embodiment is narrow at the top and wide at the bottom, and preferably has a trapezoidal structure.
The pen cap 2 is formed with the spacing sand grip 4 of a plurality of sections of interval arrangement on the internal perisporium that corresponds cooperation section 102 department, and this spacing sand grip of a plurality of sections is the helical structure who arranges along same circumference, and the interval between every two adjacent spacing sand grips forms guide way 5. The length of these spacing sand grip 4 of a plurality of sections is unanimous and spiral angle is unanimous, and the top of the spacing sand grip of these a plurality of sections all is in on same circumference, then the bottom of the spacing sand grip of these a plurality of sections also all is in on same circumference, and the length of spacing sand grip 4 is greater than the length of direction sand grip 3 in addition, and the length of the direction recess 5 that forms like this also is greater than the length of spacing sand grip 4. Because the direction sand grip is equipped with two sections in this embodiment, then spacing sand grip 4 is equipped with the three-section at least and constitutes two at least guide groove 5, and the even interval distribution of spacing sand grip is on the internal perisporium that the corresponding direction sand grip of cap for a brush department, and the spacing sand grip that sets up in this embodiment is 12 sections, does not do the injecing in this application of this concrete quantity to the space of the guide groove who forms can hold the direction sand grip as the standard. Spacing sand grip also designs for radial boundary is under the narrow wide form (preferred trapezoidal form structure) in going up in this application, then the guide way that forms is under the wide narrow form, with the radial cross-section phase-match of the direction sand grip of holding in the guide way to the more smooth removal of following the guide way of guide sand grip.
Based on structure between the cooperation section of above-mentioned pen-holder and the internal perisporium of cap for brush, 3 spiral cooperations of direction sand grip are connected in direction recess 5, and this direction sand grip can rotate and then drive cap for brush along direction recess spiral when rotating pen-holder or cap for brush and follow pen-holder axial reciprocating positioning and remove.
In addition, a circle of bosses 6 are formed at the connection part of the barrel body 101 and the matching section 102 along the circumferential direction, and the outer side surfaces of the bosses and the outer side surfaces of the guide convex strips 3 are on the same circumferential surface. The lower extreme of pen-holder main part is along carrying on contracting in promptly and forms round step-like structure between pen-holder main part and cooperation section, and this step-like structure is boss 6, and this step-like structure periphery side protrusion is just as high with the periphery side of direction sand grip 3 in cooperation section periphery side, and the cap can also be fixed a position through this boss except can through the cooperation on the cooperation section.
this application the pen structure is when the pen cap is overlapped, with the pen-holder tip of pen-holder and cooperation section along the axial insert one end open-ended pen cap in, direction sand grip on the pen-holder cooperation section can follow the direction recess rotation on the pen cap inside wall when rotating pen cap or pen-holder to make the pen cap location on the cooperation section of pen-holder, can utilize boss 6 to further fix a position the pen cap on the cooperation section simultaneously. When the pen cap is detached, the pen holder and the pen cap are respectively held by two hands, the pen cap can be automatically detached conveniently only after the pen holder is rotated anticlockwise or clockwise for a certain angle, and the pen cap is not required to be pulled down by using great strength like the prior art, so that a pen is used conveniently.
The pen structure is improved on the existing pen holder and pen cap, a plurality of limiting convex strips are arranged in the pen cap to form guide grooves, the guide convex strips are arranged on the matching section of the pen holder, and the pen cap can be easily detached only by rotating the pen holder clockwise or anticlockwise relative to the pen cap by ingeniously utilizing the mutual meshing between the guide convex strips and the guide grooves; the pen structure is simple and compact in structure, convenient and labor-saving to operate, easy to machine and low in cost, breaks through the traditional thinking mode and structure, overturns the structural design of the pen in the writing tool industry, improves the technical height and innovation capacity of the industry, is convenient and practical to use, saves more time and labor, and adds the novelty of the whole pen.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
