Abstract

The utility model discloses a wooden holder pencil with a rubber head, comprising a rubber head (1), a connecting sleeve (2), a pen holder (3) and a cartridge (4). The connecting sleeve (2) is a tubular plastic sleeve with a uniform inner cavity and a smooth inner wall without any bulged lines and barriers and the area that one end of an outer wall is 1 cm away from an end-face is provided with 12-16 strips bulged longitudinal lines. One end of the connecting sleeve (2) with the lines is sheathed with the rubber head (1) and the other end is sheathed with the pen holder (3). When the rubber head (1) is in the same level with the end-face of the connecting sleeve (2), one end of the pen holder (3) with the connecting sleeve (2) is downward to form a 45 degrees angle with a table top (not being equal with 90 degrees) and is pressed on the table top or a paper. When the pen holder (3) is pressed lightly, a small segment rubber head (1) can be pressed out, and when the pen holder (3) is cut into an inconvenient situation by hand, one end of the connecting sleeve (2) without the pen holder (3) is sheathed with a pen holder with the same type, while if the pen holder (3) is shorter the pencil can lengthen service life. The utility model can fully improve the availability ratio of the rubber head (1) and the cartridge (4) and has the advantages of simple structure and easy manufacturing.

Description

A kind of Wood-bar pencil with rubber tip

Technical field

The utility model relates to a kind of cultural goods, especially a kind of Wood-bar pencil with rubber tip.

Background technology

At present, the Wood-bar pencil of the band rubber tip of selling on the market, use to penholder be left 3-5cm, when holding inconvenience and discard, cause utilization rate low, waste is big.Pen core has more than 20% and is not utilized generally speaking, and rubber tip has more than 50% and is not utilized.In recent years, proposed some schemes in the society and solved this type of problem, the overwhelming majority is not utilized because of increasing new material consumption.Thereby the waste problem of the Wood-bar pencil of band rubber tip is not effectively solved.

The utility model content

For overcoming above-mentioned the deficiencies in the prior art, the utility model provides the Wood-bar pencil of the band rubber tip that a kind of pen core and rubber tip can make full use of.

For solving above-mentioned the deficiencies in the prior art, the technical solution adopted in the utility model is: described a kind of Wood-bar pencil with rubber tip, it is made up of rubber tip, adapter sleeve, penholder and pen core.Described adapter sleeve is a tubular plastic sheath, and inner chamber size is consistent, and inwall is bright and clean, the lines of no any projection and barrier; Described penholder two ends are 45 ° of chamfering 0.2-0.4mm.When rubber tip with to the time with the end face of adapter sleeve, the end that penholder is had an adapter sleeve is 45 (be not equal to 90 ° all can) with desktop downwards and is pressed on desktop or the paper, pushes penholder with light power, can be by a bit of rubber tip use of extrusion; When penholder is cut when holding inconvenience, there is not the penholder of a same model of an end socket of penholder at adapter sleeve, can continue long the use with short penholder.

The beneficial effects of the utility model are: can fully improve the utilization rate of rubber tip and pen core, cut the waste, and the favorable environment protection, and simple in structure, easy to manufacture.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model front view.

Fig. 2 is the utility model longitudinal sectional drawing.

The specific embodiment

Structure of the present utility model is made up of rubber tip 1, adapter sleeve 2, penholder 3 and pen core 4 as shown in Figure 1 and Figure 2.Adapter sleeve 2 is a tubular plastic sheath, wall thickness 1-1.5mm, and inner chamber size is consistent, and inwall is bright and clean, the lines of no any projection and barrier; Vertical lines that are provided with 12-16 bar projection from end face 1cm zone of outer wall, the angle of cut of two ends end face and inside and outside wall is 90 °, in order to pushing rubber tip 1 and continued access penholder 3; Penholder 3 is cylindrical or multi-edge column-shaped, and its adapter sleeve 2 is cylindric, and adapter sleeve 2 intracavity diameters equal the outside diameter of cylindrical penholder 3 or the circumscribed circle diameter of multi-edge column-shaped penholder 3.Penholder 3 can also be other shape, and adapter sleeve 2 inner chamber cross sections are equal to the cross section of penholder 3.Penholder 3 two ends are 45 ° of chamfering 0.2-0.4mm, in order to pushing rubber tip 1 and continued access penholder 3; The cross section of rubber tip 1 is slightly less than the inner chamber cross section of adapter sleeve 2, and rubber tip 1 is sleeved on adapter sleeve 2 outer walls of lines, the other end cover Pencil joint holder 3 of adapter sleeve 2.When rubber tip 1 usefulness to the end face of adapter sleeve 2 time, the end that penholder 3 is had an adapter sleeve 2 downwards and desktop be 45 (be not equal to 90 ° all can) and be pressed on desktop or the paper, push penholder 3 with light power, can be interior by extruding a bit of rubber tip 1 use that length equals adapter sleeve 2 wall thickness from adapter sleeve 2.So for several times, rubber tip 1 almost all can be pushed out and use up.When penholder 3 is cut when holding inconvenience, penholder 3 retreated to account for half position of adapter sleeve 2 (if rubber tip does not use up, use separately by going out rubber tip earlier), penholder at the same model of an end socket of adapter sleeve 2 no penholders 3, account for half length of adapter sleeve 2 inner chambers, with with short penholder 3 end faces near, can be with short penholder 3 continuous long uses.

Claims

1, a kind of Wood-bar pencil with rubber tip is made up of rubber tip (1), adapter sleeve (2), penholder (3) and pen core (4), it is characterized in that: described adapter sleeve (2) inner chamber size is consistent, and inwall is bright and clean, the lines of no any projection and barrier.
