Improvement of refill telescopic control structure

This creation relates to an improvement of a retractable telescopic control structure, especially a pen that can be pushed out by rotation when used, and can be used to retract the pen in the pen tip when not in use, and the pen is conveniently assembled. Improvement of the core telescopic control structure.

Generally, the structure of the telescopic retractable pen is rotated, and the structure is generally as shown in FIG. 1 , and a rotating seat 11 is disposed on the rotating base 11 with a sleeve 12 having a diagonally-shaped hole 121 . The sliding seat 13 provided with the protruding point 131 is sleeved on the sleeve 12, and the rotating seat 11 and the sleeve 12 are sleeved on a fixing sleeve 16 and then placed on the pen tube 10, and the top of the core 14 is placed. The sleeve is placed under the slide 13, and the rotation of the rotary seat 11 is caused by the pen tube 10 to move the slide 13 up and down along the sleeve 12, thereby controlling the expansion and contraction of the refill 14, wherein the refill 14 is pushed down. There is no problem in making it extend, but when the slider 13 moves up, the refill 14 cannot be retracted accordingly. Therefore, the conventional pen needs to be placed with a spring 15 at the bottom end of the refill 14 The tension of the spring 15 causes the refill 14 to be pushed up to retract to the barrel. This method is less convenient to assemble, and it is not desirable to add a spring 15 element. In view of this, the applicant has been engaged in this business for many years. After continuous research and experimentation, Yan Mengsheng improved a retractable telescopic control structure to make it easier to assemble and use the pen.

The main purpose of this creation is to provide a refinery control structure. Good, the pen can be used to rotate the refill when it is used, and can be retracted into the pen tip by positioning when not in use, which is convenient to assemble and can reduce the assembled components and reduce the assembly cost.

The improvement of the refill telescopic control structure comprises a sliding seat, a rotating seat, a fixing sleeve, and a positioning component and a fitting component. Wherein, the rotating seat is provided with a sleeve, and the sleeve is provided with a diagonally-shaped cross-section, the sliding seat comprises a positioning portion, and a sleeve portion extending downward from the positioning portion and having a smaller diameter is disposed at the positioning portion. The upper edge is provided with a sliding section with a protruding point, and the outer edge of the sliding seat and the fitting part is provided with a groove arranged at intervals, so that the top edge of the refill is embedded in the fitting portion, and the sliding section of the sliding seat is The protruding point is engaged with the cutting hole of the rotating seat, so that the sliding seat and the upper edge of the rotating seat are placed on the positioning member and the fitting member, and then placed on the upper pen tube, and the sliding seat is rotated along the rotating seat by the rotation of the upper pen tube The upper slide down, and then the control refill is extended from the bottom end of the pen tube for writing, or retracted into the pen tube for carrying.

The improvement of the refill telescopic control structure described above, wherein the sleeve portion under the sliding seat is set to a thin wall surface to have appropriate elasticity to facilitate the insertion of the refill.
