Abstract

The utility model discloses a ballpoint pen convenient to assemble and disassemble. The ballpoint pen comprises a pen container, a pen cap, a pen refill and a spring. The pen refill is arranged in the pen container, a notch is formed in the middle of the pen cap, the lower end face of the notch of the pen cap is connected with an upward extending extension block, the upper end of the extension block is connected and provided with an outward raised triangular protruding rib, an outward raised oval protruding block is arranged in the middle of the extension block in a connected mode, the oval protruding block is vertically located under the triangular protruding rib, the width of the triangular protruding rib in the radial direction is smaller than the width of the oval protruding block in the radial direction, a triangular through hole allowing the triangular protruding rib to be embedded and an oval through hole allowing the oval protruding block to be embedded are correspondingly formed in the upper end of the pen container, and the axial length of the oval through hole is larger than that of the oval protruding block. Compared with the prior art, the ballpoint pen is easier and more convenient to disassemble and assemble, thereby greatly improving assembling and disassembling efficiency.

Description

A kind of ball pen of being convenient to handling

Technical field

The utility model relates to a kind of pen, is specifically related to a kind of ball pen of being convenient to handling.

Background technology

At present, ball pen all includes pen container, pen core and the cap for brush usually, pen core all is installed in pen container, because described pen core needs periodic replacement after use, and the pen container of existing ball pen mostly is to be threaded by upper pen container and lower pen container and forms, therefore, when changing pen core, need the multiple rotary pen container, handling are inconvenience comparatively, wastes time and energy.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of ball pen of being convenient to handling.

For achieving the above object, the utility model provides a kind of ball pen of being convenient to handling, comprise pen container, the cap for brush, pen core, spring, described pen core is installed in pen container, offer the lower end through hole passed for the nib on described pen core on the lower end surface of pen container, the middle part of described pen core is connected with lug, described spring housing is loaded on the lower end of pen core, and the two ends of spring respectively with pen core on lug, pen container inwall butt, offer the upper end through hole of packing into for the described cap for brush on the upper end end face of described pen container, offer the groove inserted for described pen core upper end on the lower end surface of the described cap for brush, the middle part of the described cap for brush offers breach, and be connected with upwardly extending extension block on the lower surface of described cap for brush breach, be connected with the triangle convex tendon of an outwardly convex on the end, upper end of described extension block, the middle part of described extension block is connected with the oval projection of an outwardly convex, and described oval projection be positioned at the triangle convex tendon vertically under, the radial width of described triangle convex tendon is less than the radial width of described oval projection, the corresponding triangle through hole entered for described triangle convex tendon setting-in and the ellipse hole entered for described oval projection setting-in of offering on the upper end of described pen container, and the axial length of ellipse hole is greater than the axial length of oval projection.

The beneficial effects of the utility model are: adopt said structure, while dismantling ball pen provided by the utility model, only need press the extension block on the cap for brush, make the triangle convex tendon on it break away from the triangle through hole, reach oval projection disengaging ellipse hole, rotate a little again cap for brush certain angle, just the described cap for brush can be pulled out from pen container, realize the dismounting to ball pen; While re-assemblying, also only the described cap for brush need be inserted in the upper end through hole of pen container, and make triangle convex tendon embedding on it be encased in described triangle through hole, and oval projection embedding be encased in described ellipse hole, just can realize the assembling to ball pen, whole process is simple and convenient, has greatly improved compared to existing technology the efficiency of loading and unloading.

The outer end end face that the utility model can further be set to described triangle convex tendon is downward-sloping inclined plane, and the outer end end face of described oval projection is arcwall face.

Adopt said structure, the outer end end face of described triangle convex tendon is arranged to downward-sloping inclined plane, can be convenient to the described cap for brush and insert in the upper end through hole of pen container; The outer end end face of described oval projection is arranged to arcwall face, the feel in the time of can increasing the user and press.

The utility model also can further be set to also be provided with the helical form convex tendon on the outer circumference surface of the described cap for brush.

Adopt said structure, set up the helical form convex tendon on the outer circumference surface of the described cap for brush, can be convenient to the rotation of the relative pen container of the described cap for brush, thereby the described cap for brush is more easily disassembled from pen container.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is structure explosive view of the present utility model;

The structural representation that Fig. 3 is the cap for brush in the utility model.

The specific embodiment

As Fig. 1, 2, provided a kind of ball pen of being convenient to handling shown in 3, comprise pen container 1, the cap for brush 2, pen core 3, spring 4, described pen core 3 is installed in pen container 1, offer the lower end through hole 11 passed for the nib 31 on described pen core 3 on the lower end surface of pen container 1, the middle part of described pen core 3 is connected with lug 32, described spring 4 is set on the lower end of pen core 3, and the two ends of spring 4 respectively with pen core 3 on lug 32, pen container 1 inwall butt, offer the upper end through hole 12 of packing into for the described cap for brush 2 on the upper end end face of described pen container 1, offer the groove 21 inserted for described pen core 3 upper ends on the lower end surface of the described cap for brush 2, the middle part of the described cap for brush 2 offers breach 22, and be connected with upwardly extending extension block 23 on the lower surface of described cap for brush breach 22, be connected with the triangle convex tendon 24 of an outwardly convex on the end, upper end of described extension block 23, the middle part of described extension block 23 is connected with the oval projection 25 of an outwardly convex, and described oval projection 25 be positioned at triangle convex tendon 24 vertically under, the radial width of described triangle convex tendon 24 is less than the radial width of described oval projection 25, the corresponding triangle through hole 13 entered for described triangle convex tendon 24 setting-ins and the ellipse hole 14 entered for described oval projection 25 setting-ins of offering on the upper end of described pen container 1, and the axial length of ellipse hole 14 is greater than the axial length of oval projection 25.The outer end end face 241 of described triangle convex tendon 24 is downward-sloping inclined plane, and the outer end end face 251 of described oval projection 25 is arcwall face.Also be provided with helical form convex tendon 26 on the outer circumference surface of the described cap for brush 2.
