Description

Rotary marking crayon

Technical Field

The utility model relates to a marking tool especially relates to rotation type mark crayon.

Background

Crayons are generally made by mixing paraffin wax and pigment, and are generally rod-shaped in their conventional shape. The crayon in the early stage is prepared by directly mixing raw materials to prepare a rod-shaped crayon core, and then wrapping the exterior of the crayon core with wrapping paper, but the crayon with the structure is not convenient in the processes of storage, transportation and use, is easy to break and damage, is easy to contact with the crayon core material in the process of use, dirties hands and is not easy to clean.

Later, crayons with a casing appeared, which structurally included a barrel with a cylindrical cavity, the rear of the barrel having a tail, the inner wall of the tail having threads, a screw rod in the barrel, one end of the screw rod connected to the inner wall of the tail by the threads on the surface of the screw rod, and the other end of the screw rod fixed to one end of the crayon core. The crayon can move back and forth in the penholder by the rotation of the screw rod, so that the crayon can be rotated to the head part of the penholder to be protruded out of the penholder when in use, and the crayon can be rotated to the tail part of the penholder to be retracted into the penholder cavity without being rotated in the opposite direction. However, the prior art structure of the rotary crayon has some defects that the crayon is easy to be used: in the using process, the phenomenon that the crayon core is separated from the screw rod after being screwed out easily occurs, so that the crayon core cannot be screwed back into the cavity of the penholder after being screwed out; in addition, after the pencil is used for many times, the screw rod is in threaded contact with the inner wall of the pencil tail, so that slipping is easy to occur, and the wax pencil core cannot be smoothly screwed out during rotation.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1, which comprises a top sleeve 1 and a hollow pen holder 4 rotationally connected with the top sleeve 1;

for convenience of processing and product assembly, a gasket 10 can be inserted at the top of the hollow pen holder 4, and the top sleeve 1 is rotatably connected with the gasket 10. The gasket 10 may be made of metal, and plays a role of transition.

The hollow pen holder 4 is internally provided with a support rod 2 in a penetrating way, and the support rod 2 is fixedly connected with the top sleeve 1.

The fixing structure is shown in fig. 1, a solid base 21 is fixedly connected to the top of the support rod 2, and a spring plate 22 is fixedly connected to the top of the base 21. The elastic sheet 22 is composed of two rod-shaped flexible members with the middle inclined outwards, and the ends of the flexible members are inclined downwards to form two symmetrical barbs.

In addition, in order to match the structure of the elastic sheet 22, a step structure 11 with an opening in the middle is arranged in the top sleeve 1.

Wherein the solid base 21 serves as a reinforcement. During the assembly, wear to establish into the top of stair structure 11 through the opening from the bottom after compressing shell fragment 22, its barb butt live stair structure 11's up end after resumeing, and its downward motion is spacing by the barb, and the fixed interior edge that butts stair structure 11 of shell fragment.
