Description

Portable glue pen

Technical Field

The utility model relates to a stationery, concretely relates to portable glue pen.

Background

The glue is an essential object for daily work, study and life of people, and the portable glue pen is convenient to carry and use. There are also such glue pens in the market at present, for example, chinese patent No. 93212902.1 discloses a portable glue pen, which is composed of a pen cap, a hard pen container, a soft pen container, a pen point and a pen cap. A through needle is arranged on the axis position of the top end of the pen cap, and after the pen cap is inserted into the soft pen container, the through needle extends into the pore of the pen head. The cylindrical end of the pen point is connected with the soft pen container, and the other end of the pen point is in a brush shape. The glue pen has the advantages of controllable glue taking amount, uniform glue coating, difficult blockage, portability, convenience and repeated use. However, when the glue pen is used, the flow of the pen cap after being pulled out is not easy to control, and in addition, along with continuous pulling out, the matching hole between the through needle and the pen container is larger and larger, so that the matching is not tight, and the overflow of the glue is caused.

In order to solve the problem of glue overflow, the prior chinese patent No. 200920121529.3, a portable glue pen, includes a pen body, a refill, a pen cap and the pen body are clamped, a cavity for holding glue is provided in the pen body, a fixing member is provided at the middle lower part of the pen body and clamped on the pen body, the lower end of the pen body is provided with the refill, the upper end of the refill is supported on the fixing member in the pen body through an elastic member, an elastic sheet made of the elastic member and the refill are made into an integral piece, the elastic sheet is an initial point which is uniformly distributed in the circumferential direction and extends upwards and spirals to be spiral, and the lower end of the refill is in sealing fit with the opening at the lower end of the pen body. This glue pen can play and avoid glue to spill over, but the lower part still need set up a mounting in the body, and elastomeric element adopts three flexure strips, and the elastic component supports on the mounting, and this kind of structure is more complicated to the setting up of mounting makes out to glue smoothly inadequately, sometimes still can cause the emergence of gluing the difficulty. Further improvement in structure is therefore desired.

Disclosure of Invention

The utility model aims to solve the technical problem that a portable glue pen that the structure is simpler, convenient to use is provided to foretell technical current situation, not only can not put on the pen socket and also can not produce glue and spill over after removing external force, goes out to glue moreover and more smoothly.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a portable glue pen, includes handwriting and refill, is equipped with the cavity that is used for holding glue in the handwriting, and the refill sets up the lower extreme at the handwriting, its characterized in that: a hollow elastic part is supported between the upper end of the refill and the inner wall of the cavity of the pen body, the refill is arranged at the lower end of the pen body in a telescopic mode through the elastic part, and the lower end of the refill is in sealing fit with the opening at the lower end of the pen body.

As an improvement, the pen body comprises a pen body and a pen point, the pen point is inserted and fixed at the lower end of the pen body in a size matching or threaded connection mode, and a conical opening matched with the lower end of the pen core is formed in the lower end of the pen point.

And the elastic part is in a structure of gradually reducing the diameter downwards, an annular step which is abutted against the upper end of the elastic part is annularly arranged on the inner wall of the middle lower part of the cavity of the pen body, a convex ring which is abutted against the lower end of the elastic part is annularly arranged on the upper part of the pen core, and the elastic part is supported between the pen body and the pen core, so that the pen core has the tendency of always extending outwards.

And finally, the elastic piece is a precision spring, the upper end of the precision spring is placed on the annular step surface of the pen body, and the lower end of the precision spring is sleeved on the upper end of the pen core and is abutted and fixed with the convex ring.

Compared with the prior art, the utility model has the advantages of: the original fixing piece structure is cancelled, the structure is simplified, and glue is convenient to discharge; the elastic piece adopts a precise spring, so that the elastic piece has more stable elasticity, more linear force change and uniform force application compared with a plastic elastic piece under different temperature environments, and the glue is more smoothly discharged; the elastic piece and the pen core are designed to be non-integrated pieces, so that the pen core is convenient to process and disassemble and convenient to replace. The utility model has the advantages of simple and reasonable structure, convenient to use, after removing external force, the refill can recover automatically, will export sealedly, can not cause glue to spill over, paints evenly simultaneously, goes out to glue smoothly.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, 2 and 3, a portable glue pen comprises a pen body and a pen core 3, wherein a cavity 11 for containing glue is arranged in the pen body, the pen core 3 is arranged at the lower end of the pen body, the pen body comprises a pen body 1 and a pen point 2, the pen body 1 is of a columnar structure with an opening at the lower end, the pen point 2 is inserted and fixed at the lower end of the pen body 1 in a size matching or threaded connection mode, the pen core 3 is arranged in the pen point 2, and a conical opening 21 matched with the lower end of the pen core 3 is formed at the lower end of the pen point 2; a hollow elastic part 4 is supported between the upper end of the refill 3 and the inner wall of the cavity 11 of the pen body 1, the refill 3 is telescopically arranged at the lower end of the pen body through the elastic part 4, and the lower end of the refill 3 is in sealing fit with the conical opening 21 at the lower end of the pen point 2; elastic component 4 is a precision spring, it is more stable to compare plastics spring elasticity under the different temperature environment of precision spring, the dynamics changes more linearly, elastic component 4 is the structure of down gradually reducing the diameter, the hoop is equipped with the annular step 12 that offsets with elastic component 4's upper end on the lower part inner wall in 11 of body of a brush, the upper portion hoop of refill 3 is equipped with the bulge loop 31 that offsets with elastic component 4's lower extreme, elastic component 4's upper end is shelved on body of a brush 1's annular step 12 face, elastic component 4's lower pot head is established and is offset fixedly with bulge loop 31 in refill 3's upper end, make refill 3 have the trend of outwards stretching out all the time.

When the pen is used, the pen point 2 is placed on the surface of an object needing glue coating, the pen core 3 is pressed down forcibly, due to the adoption of the elastic part 4, when the elastic part receives a reaction force, the elastic part is compressed, the pen core 3 moves inwards and is separated from the lower end conical opening 21 of the pen point 2, the cavity 11 in the pen body is communicated with the outside, glue can slowly flow out, after the glue flows out of a required using amount, the external force is removed, the pen core 3 resets under the action of the elastic part 4, the conical opening 21 is automatically sealed, the glue does not flow out any more, the pen sleeve does not need to be sleeved after being used up every time when the pen is continuously used in a short time, and the use is very convenient.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
