Description

Automatic marking tool with multi-section core

Technical Field

The invention relates to a marking tool structure, in particular to an automatic structure of a multi-section type core body and a free-sharpening pencil which are overlapped up and down from one section to the other section.

Background

Currently, the pencil on the market basically comprises three types, namely a wooden pencil, a mechanical pencil and a sharpening-free pencil.

Wooden pencils, because of the need to use a large amount of wood, are not in line with the development trend of green ecology today, which pay attention to environmental protection. And a wood pencil cannot be used after being removed and consumed to a certain length, so that the really usable length of the wood pencil is only one third of the whole length. In order to maintain smooth writing, a simple tool is required to roll the wooden pencil, so that the wooden pencil is dangerous and not clean, and the household expense is increased by using a pencil sharpener, so that the wooden pencil is not environment-friendly.

The propelling pencil is conforming to the needs of people for convenient use. Because the automatic core feeding machine does not need to roll and cut, the automatic core feeding machine can automatically or semi-automatically feed cores, and is accepted and favored by people. For writing of more complex characters, the mechanical pencil uses a thinner pencil lead, which is easy to break, and when writing, the wooden pencil is still not weakened due to the fact that the pencil lead is harder and the writing feel is far less good than that of the wooden pencil.

The sharpening-free pencil is usually formed by sequentially stacking replaced section lead cores. When the lead needs to be replaced, the worn-out segment core needs to be manually detached, and then the old lead can be replaced by a new lead. The pencil without sharpening adopts various pencil leads with different hardness and thickness, although the writing feeling is comparable with that of wooden pencil. However, the use mode of the pencil is not portable of the mechanical pencil, and the mechanical pencil cannot be used as long as one mechanical pencil has less pencil lead, so that the mechanical pencil has a lower market share since the mechanical pencil is popular.

Therefore, how to make the sharpening-free pencil keep all the benefits of the wooden pencil, further has the advantages of the mechanical pencil, and further has the diversity of stationery to provide lively children to like to use, which is an important problem to be solved at present.

Detailed Description

The technical means adopted by the invention to achieve the preset aim are further described below by matching with the drawings and the preferred embodiments of the invention.

Referring to fig. 1 and 2, an automatic marking tool with a multi-section core according to a first embodiment of the present invention is shown; comprising the following steps: a rod body 10, a pushing assembly 20, an elastic device 30, a pushing mechanism 40 and a positioning cap 50;

A rod 10, the rod 10 has two

ends

101, 102 and is hollow and tubular, and is provided with an inner cavity 103, one end 102 of the rod 10 is an outlet 104 of the multi-section core, and the other end 101 is an inlet end of the pushing assembly 20. An annular shrinkage part 105 is arranged at the inner edge of the inner cavity 103 near one end 102, the size of the shrinkage part 105 is smaller than that of the inner cavity 103, and the shrinkage part 105 extends towards the outlet end 104 of the multi-section core body, and the shrinkage part 105 and the inner cavity 103 have inner diameters with different sizes and need to be connected through a connecting part, for example, the shrinkage part and the inner cavity can be directly connected by adopting a stepped step or other modes. However, in this embodiment, the engagement portion is a tapered surface 106, so that the inner diameter of the inner cavity 103 of the rod 10 gradually decreases to a size equal to that of the tapered portion 105. A step 107 is provided at the proximal end of the shaft for carrying the resilient means 30.

A push assembly 20 comprising a push inner rod 201 and a push mechanism 40: the pushing inner rod 201 has two

ends

2011, 2012 and is hollow and penetrated by a hollow tube 2018, and the hollow tube can be sequentially filled with a plurality of sections of cores. One end 2011 of the push inner lever 201 is a pressing end, the other end 2012 is provided with the push mechanism 40, and a gear boss 2013 is provided near the pressing end 2011. After the push inner rod 201 and a push mechanism 40 are assembled as the push assembly 20, the push assembly 20 may be accessed from the entrance of the rod 10 and installed in the interior cavity 103 of the rod 10.

The pushing mechanism 40 is disposed at one end 2012 of the pushing inner rod 201. The pushing mechanism 40 has an annular engaging end 401, and the engaging end 401 is provided with an upper edge 4011 and a lower edge 4012, wherein the lower edge 4012 engages the elastic structure 402. The elastic structure 402 is at least one or more geometrically shaped strip-like curved structures. In this embodiment, two elastic structures 402 are preferably implemented, wherein each elastic structure 402 has two

ends

4021 and 4022, and one end 4021 is engaged with a lower edge 4012 of the mating end 401. The two elastic structures 402 are approximately in a horn shape Y or a claw shape Z, (see fig. 8, the first bend 4021 of the strip-shaped elastic structure and the wedge-shaped end 401 are reduced by a first bend, the two symmetrical strip-shaped elastic structures facing each other are in a horn shape Y), and the claw shape Z is that the first bend 4021 and the second bend 4022 of the elastic structure 402 are bent at each other, so that the claw shape Z) the two elastic structures 402 are gradually compressed at the P position when passing through the necking slope 106 from the inner cavity 103. After the two elastic structures 402 return to the original positions, the two elastic structures 402 can return to the original claw shape by the elasticity of the two elastic structures. The pushing mechanism 40 may be integrally formed with the end 2012 of the push inner rod 201 or may be separate as a single piece. In this embodiment, the pushing mechanism 40 is made of a single piece so as to be made of various materials having high rigidity and high elasticity, such as high rigidity plastic, high rigidity plastic composite, high rigidity metal or other high rigidity materials having elasticity.

An elastic device 30, the elastic device 30 has two

ends

301, 302, which can provide a spiral shape for pressing. One end 302 of the elastic device 30 is arranged on the step 107 of the inner cavity 103 of one end 101 of the rod body 10, and the other end 301 is sleeved on the lower side 2014 of the gear boss 2013 of the push inner rod 201.

A positioning cap 50 is T-shaped and has two

ends

501, 502 and a through hole 503, and one end 502 is provided with a wedge portion 504. The engagement portion 504 of the positioning cap 50 is engaged with the rod body 10.

Referring to fig. 2 for assembling the automatic marking tool, after the 2011 end of the pushing inner rod 201 with the pushing mechanism 40 passes through the elastic device 30, the pushing assembly 20 is installed in the inner cavity 103 of the rod body 10, one end 302 of the elastic device 30 abuts against the step 107 of the rod body 10, and the other end 301 abuts against the gear boss 2013 of the pushing inner rod 20. After the positioning cap 50 is inserted into the through hole 503 of the inner rod 201, the inner rod is then inserted into the end 2011 of the rod body 10, and then the end 101 is inserted into the end 504 of the rod body, and the positioning cap 50 is inserted into the end by locking or sleeving, gluing, clamping or other conventional techniques. In this embodiment, the positioning cap 50 is engaged with the end 101 of the rod 10 by locking.

Referring to fig. 3, the pushing inner rod 201 is filled with a plurality of stacked multi-section cores T, including cores T1, T2, T3, T4, and T5. Each of the multiple-section cores T has two ends. As shown in fig. 4, the core body T2 arranged at the second position has a wide end T21 and a writing end T22 at one end and is slightly conical; in use, when the pushing assembly 20 is pushed to push the inner rod 201 to move, the elastic structures 402 of the pushing mechanism 40, which are approximately claw-shaped Z, are interfered by the shrinkage slope 106 of the inner cavity 103 of the proximal end 102 of the rod body 10, and the caliber of the two elastic structures 402 of the claw-shaped Z is gradually changed (the pressure direction is as shown by the arrow) and is smaller than the wide end T21 of the core T2, so that one end 4022 of the two elastic structures 402 is propped against the upper T23.

As shown in fig. 5, when the inner rod 201 is pushed further at one end 2011, the worn core T1 is arranged below the multi-section core T2, and is pushed out of the outlet end 104 of the rod body 10, and the core T2 is limited in the outlet end 104 and replaced with a new one.

As shown in fig. 6, when the hand-release pushing assembly 20 pushes one end 2011 of the inner rod 201, the pushing inner rod 201 is restored to the original position by the elastic device 30 to wait for the next pressing. While in the process of returning to the original position, the elastic structure 402 of the claw shape Z of the pushing mechanism 40 at one end of the pushing inner rod 201 will, when not returning from the necking 105 to the position of the inner cavity 103 with a wider diameter, take the core T3 with a caliber larger than that of the elastic structure 402 together with the remaining cores T4 and T5 placed in the pushing inner rod 201 upward (as an arrow) until the elastic structure 402 returns to the position of the inner cavity 103 with a wider diameter.

As shown in fig. 7, the elastic structure 402 of the claw Z returns to the original state by its shape structure and elastic resilience of the material, and the caliber (as indicated by the arrow) of the elastic structure 402 is opened. The sectional type multi-section core T3 falls into the position of the core T2 as shown in fig. 3, and the cores T4 and T5 are arranged downwards, so that the process of pressing the automatic core-out for one time is completed, and then, after all the cores mounted on the push inner rod 201 are used up by repeating the pressing operation, new cores are mounted from one end 2011 of the push inner rod 201.

As shown in fig. 8, in one embodiment, each elastic structure 402 of the strip shape has at least a first bend 4021 and a second bend 4022, wherein the first bend 4021 and the second bend 4022 have a bendable elasticity, and each elastic structure 402 is bent outwards towards the central axis of the rod 10, so that the first bend 4021 of the two elastic structures 402 of the embodiment looks like a horn Y, and the second bend 4022 looks like a claw Z.

As shown in fig. 9, the first bend 4021 and the second bend 4022 mainly exclude various possible factors, which cause the multi-section core T to clamp the elastic structure 402 between the shrinkage section 105 and the multi-section core T, so that the single thickness dimension of the elastic structure 402 does not exceed the gap dimension between the inner wall of the shrinkage section 105 and the multi-section core T in design.
