Abstract
The utility model discloses a pencil without peeling which has a simple structure and does not adopt the lumber to make a pencil holder. An assembled lead cord sleeve is utilized to be made into a lead cord having a certain shape to be arranged in the pencil holder of the pencil without peeling; the lead cord in the lead cord sleeve can be pushed to the front side of the pencil head one by one by the compression or compression bar device of the rear end of the pencil holder; a resistance increasing ring is arranged in the pencil head, and can prevent the lead cord naturally gliding or moving up; the pencil without peeling which has a simple structure and does not adopt the lumber to make a pencil holder is used for writing and drawing.
Description
The utility model be a kind of be used to write paint the sharpening free pencil of retouching.
Existing commercially available pencil is many makes pencil shaft with wood materials, the annual timber resources that consumes many preciousnesses, and pencil is whenever cut and once can only be used certain hour to cut could to use very sense inconvenience more again.Though existing have a kind ofly make the propelling pencil of pencil shaft without timber, only be suitable for thinner lead for retractable pencil, lead for retractable pencil frangibility when writing, and because of lead for retractable pencil is thinner is painted and others such as is retouched and all be restricted.
The purpose of this utility model is that design is a kind of simple in structure, with low cost, easily is popular acceptance, and pleased use can be write and paint the device of pencil easily of retouching and not cutting in use without timber again.
The utility model is: lead for retractable pencil is made the lead button of definite shape, and the various shape that needn't cut again in use, is contained in two ends for no reason in the lead core cover at the end, and lead core cover is packed in the leading portion of sharpening free pencil penholder.Design has at least two to increase resistance circle and increase the resistance circle with bigger materials such as the rubber making of coefficient of friction in the nib of penholder leading portion front, be used for stoping the lead for retractable pencil natural downslide or on move, two increase have a smooth packing ring made from metal or hard material not make between the resistance circle to increase the resistance circle with lead for retractable pencil wrap up in touch too tight.Device in the penholder back segment can be passed the lead for retractable pencil in the lead core cover in the leading portion one by one from the penholder back segment to written front, calm the anger or the pressure lever type device such as any one.Can put into rubber erasers in the tail of penholder back.
The utility model has been owing to designed and lead for retractable pencil is made definite shape be contained in the lead core cover, and utilizes the device of penholder back segment the lead for retractable pencil in the lead core cover can be passed before with the purpose nib, can conveniently be used to write paint retouch etc.Lead for retractable pencil uses up each time only changes the lead core cover that cover installs lead for retractable pencil, and penholder can use for a long time.Non-sharpenning lead for retractable pencil when this sharpening free pencil uses can be saved the timber that consumes because of the manufacturing Wood-bar pencil in a large number again, and with low cost, is easily liked accepting by popular.

Describe in detail below in conjunction with accompanying drawing: shown in Fig. 1,2,3,4, lead for retractable pencil (1) or lead for retractable pencil (2) are to make various shape with required, are contained in the lead core cover (3), simultaneously with the required cushion piece (4) of loading onto.Shown in Fig. 1,2,5, design in the nib (5) to have and increase resistance circle (6) and increase resistance circle (8), its act as stop lead for retractable pencil (1) or lead for retractable pencil (2) natural downslide or on move, smooth packing ring (7) then encloses (8) and wraps up in to touch too tightly and establish for making lead for retractable pencil (1) or lead for retractable pencil (2) not increased resistance circle (6) or increasing resistance.Anterior available being threaded of nib shown in Fig. 1,2,5,6 (5) and penholder leading portion (10), connecting portion has sealing ring (9).The lead core cover (3) that lead for retractable pencil (1) or lead for retractable pencil (2) are housed shown in Fig. 1,2 is contained in the penholder leading portion (10).Fig. 1,2,6, shown in 7,8, the rear portion of penholder leading portion (10) and penholder back segment (12) or penholder back segment (13) are connected with screw thread, connecting portion has seal washer (11), when penholder leading portion (10) just becomes a kind of air pressing type sharpening free pencil with penholder back segment (12) when being connected, when penholder leading portion (10) just becomes a kind of pressure lever type sharpening free pencil with penholder back segment (13) when being connected.The front portion of the rear portion of penholder back segment shown in Fig. 1,2,7,8 (12), penholder back segment (13) and a tail (14) is with being threaded.The rear portion that rubber erasers (16) that rubber erasers lasso (15) packages or rubber erasers (16) directly are contained in a tail (14) is equipped with at the rear portion of tail (14).
The mode of calming the anger of air pressing type sharpening free pencil can be multiple, here lifting a kind of mode of calming the anger is described: as Fig. 1, shown in 7, upwards promote pressure rod (17) with finger, spring (18) in the penholder back segment (12) is compressed, nut cushion block (22) cushion rubber (21) slide block (20) nut (19) of leading on pressure rod (17) all moves up with pressure rod (17), because cushion rubber (21) slide block (20) is not fixed on the pressure rod (17), in last process of moving, 1-4 bar groove on the pressure rod has air to flow to the front portion of penholder back segment (12) from the top down, compressed spring (18) elongation was with the downward pushed home of pressure rod (17) when finger unclamped, slide block (20) cushion rubber this moment (21) is upwards withstood by air, the nut cushion block (22) that is fixed on again on the pressure rod (17) is simultaneously pushed down, cushion rubber (21) is sealed the upper end of the air inlet groove on the pressure rod, air can not upwards overflow, thereby air-flow can only promote lead for retractable pencil (1) downwards and moves to the place ahead of nib (5) and promote pressure rod (17) repeatedly by said process and just can make lead for retractable pencil (1) stretch out nib (5) front end certain-length.
The strut device of pressure lever type sharpening free pencil can be multiple, here lifting a kind of strut device is described: shown in Fig. 2,8, with finger depression bar button (24) is inwardly gently pressed, spring (25) is compressed, be connected in that button (24) is gone up and the inwall of two brake pads (26) of being close to penholder back segment (13) inwall and penholder back segment (13) leaves, the finger that is pressed in this moment on the button (24) slightly firmly pushes away downwards simultaneously, and depression bar (23) promptly moves down the lead for retractable pencil (2) that extrudes in the lead core cover (3) and stretches out nib (5) front end certain-length.
