Abstract

The utility model relates to a double-end multicore combination pen, which comprises pen core brackets of which the centers are rotationally connected in a shell. Pen cores are all movably connected on the pen core brackets by suspension parts on the end parts. The side wall of the shell is provided with long through grooves. Core outlet push buttons are arranged in the long through grooves and are in movable fit with the corresponding suspension parts. The cores can be fed at both ends of the shell. Two pen core brackets, two long through grooves and two core outlet push buttons are provided and are correspondingly arranged on the left and right parts of the shell. The middle part of the shell is provided with a pressing sleeve. Both ends of the pressing sleeve are provided with left and right press stud rotating mechanisms which are respectively matched with the pen core brackets on both sides. A compression spring is arranged between the two press stud rotating mechanisms. The outer wall of the middle part of the shell is also provided with a chute. A lower end of a core selecting push button passes through the chute and is linked with the pressing sleeve to form a double-end pushing and pressing core selection structure. The utility model innovatively designs the bidirectional core selection structure connected in the middle. The cores can be fed at both ends of the shell. Under the condition of the same shell diameter, the amount of the pen cores which can be accommodated is doubled. The double-end multicore combination pen has the advantages of compact and reasonable structure, small occupied space, convenient operation and easy carrying.

Description

Two end multicore combined pens

Technical field: the utility model relates to a kind of multiple pencil lead combined pen that can two ends uses, and particularly uses multicore combined pen thick and not flexible pen core.

Background technology: the pen core that uses as wax crayon, colored pencil, watercolor pencil etc. is thicker, not flexible and color variety abundant, often adopts the combined pen form that many pen cores are housed in the housing, makes it more practical and be convenient for carrying.It is bigger that but the shortcoming of common thick pencil lead combined pen is a diameter of the housing, and occupation space is many, and outward appearance is too clumsy, is unfavorable for actually using and carrying.If the diameter of housing is made thinner, then limited the pen core quantity that can hold, lost the multicore characteristics of multicore combined pen.

Summary of the invention: at the deficiencies in the prior art, the utility model provides that a kind of to hold the pen core number many, the two end multicore combined pens that diameter of the housing is thinner.

The utility model comprises be rotatably connected pen core support in housing of center, each pen core all is movably connected on the pen core support by the suspender of end, the sidewall of housing is provided with long groove, the knockout push button places long groove and corresponding suspender movingly, but all knockouts of two ends of housing, above-mentioned pen core support, long groove and knockout push button all have two, a corresponding left side that is arranged in housing, right-hand part, the housing middle part is equipped with gland, two ends of this gland are provided with a left side, right two snapper rotating mechanisms cooperate with the pen core support of two sides respectively, the compression spring then places resilient engagement between two snapper rotating mechanisms, housing middle part outer wall also is provided with chute, select core push button lower end pass chute and and gland be connected, constitute two ends and push and to select cored structure.

The utility model innovative design the two-way cored structure that selects of middle connection, but two ends of housing all knockout use, and open ended pen core quantity has increased by one times under the situation of identical casings diameter, and compact conformation is reasonable, occupy little space, by two snapper rotating mechanisms in the gland, housing two ends are write and can be selected any pen core flexibly for use, and are easy to operate, the good hand touch of using, external form is more attractive in appearance, and is practical, carries easily.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings: Fig. 1 is the main structure schematic diagram of embodiment;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that the stage casing A-A of Fig. 1 analyses and observe zoomed-in view.

The specific embodiment: as shown in the figure, pen core support 2 centers are rotatably connected in housing 1, and each pen core 3 all is movably connected on the pen core support 2 by the suspender 4 of end.The sidewall of housing 1 is provided with long groove 5, and knockout push button 6 places long groove 5 and corresponding suspender 4 movingly.But all knockouts of two ends of housing 1, above-mentioned pen core support 2, long groove 5 and knockout push button 6 all have two, corresponding left and right half one that is arranged in housing 1.Housing 1 middle part is equipped with gland 8, two ends of this gland 8 are provided with left and right two snapper rotating mechanisms 7 and cooperate with the pen core support 2 of two sides respectively, 10 on spring of compression places resilient engagement between two snapper rotating mechanisms 7, housing 1 middle part outer wall also is provided with chute 11, select core push button 9 lower ends pass chute 11 and and gland 8 be connected, constitute two ends and push and select cored structure.General housing 1 can be made as the three sections screw connection structures in left, center, right, assembles more convenient like this.

During use, to select core push button 9 moving to a thruster together with gland 8 along chute 11, the snapper rotating mechanism 7 of this side is pressed, and orders about 2 rotations of corresponding pen core support, the once promptly rotatable one-pen core 3 of changing of every pressure, process selects the core pen identical with common snapper rotation.When the pen core of selecting for use 3 forwarded the knockout position to, the suspender 4 of this pen core 3 matched with corresponding knockout push button 6 and is connected, and release knockout push button 6 this moment along long groove 5, this pen core 3 can be stretched out housing 1 outer the use.Generally can all arrange at the edge of each long groove 5 and be provided with a plurality of positioning tooths 13 and the cooperation of knockout push button 6 activity orientation, the extension elongation of pen core 3 is more easy to control like this.Equally, when the pen core 3 of housing 1 other end is selected, also only need and will select core push button 9 to push this side to together with gland 8, all the other operations be identical.

Present embodiment is with two identical returning springs 12 respectively on two end outer walls of gland 8, gland 8 is middle together with selecting core push button 9 to remain on like this, avoids the vibration displacement.
