Abstract
An anti-leakage water color pen comprises a hollow pen rod, a pen head, a pen cap, a water guide cartridge disposed in the pen head and a wrapped cartridge mounted in the pen rod. Due to the fact that a front anti-leakage sleeve and a rear anti-leakage cover are sleeved at the front end and the tail of the wrapped cartridge respectively, colored liquids cannot be leaked from other parts except for a liquid outlet of the water guide cartridge. The rear leakage cover at the tail can effectively prevent the colored liquid from being leaked from the tail of the wrapped cartridge when the water color pen is inverted especially during transport. A tail sleeve tube of the front anti-leakage sleeve is in matched connection with a waterproof outer film. A head sleeve tube of the front anti-leakage sleeve guides the colored liquids to flow to the water guide cartridge in the middle for concentration so as to avoid the joint of the pen head and the pen rod, and accordingly lateral leakage of the colored liquids from the front end of the wrapped cartridge when the water color pen is placed in a forward direction especially during use. The water color pen is tidy and attractive in appearance, safety to use, convenient for transport, fine in anti-leakage effect, and capable of preventing volatilization of the colored liquids to reduce waste.
Description
Technical field

Detailed description of the invention
As shown in Figure 2, a kind of Anti-leakage water color pen of the present invention, comprise the penholder 1 of hollow, nib 2, cap cap 7, be placed in diversion pen core 3 in nib 2 and the rolled core 4 that is installed in penholder 1, described rolled core 4 is made up of cylindrical waterproof adventitia 4.1 and the absorbent material 4.2 be filled in waterproof adventitia 4.1, and described diversion pen core 3 contacts with the absorbent material 4.2 in rolled core 4.Leak jacket 5 before having one is overlapped outside the front end of described rolled core 4 and the contact position of diversion pen core 3, described front leak jacket 5 comprises and is placed on rolled core 4 front end and coordinates with rolled core 4 waterproof adventitia 4.1 the tail sleeve pipe 5.1 be socketed, be positioned at the head casing tube 5.3 inside nib 2 outside diversion pen core 3, connect the transition shoulder pipe 5.2 of tail sleeve pipe 5.1 and head casing tube 5.3, the outer wall of described head casing tube 5.3 is closely by written 2 afterbody inwalls, the front end face of the spacing transition shoulder pipe 5.2 of nib 2 tail end, the leading edge of rolled core 4 waterproof adventitia 4.1 is against the rear end face of transition shoulder pipe 5.2 being limited in front leak jacket 5.The rear end face of the transition shoulder pipe 5.2 of described front leak jacket 5 is provided with the low inside and high outside continuous spacing conical surface 5.21, its role is to: this continuous spacing conical surface 5.21 can very firmly coordinate with the front end of rolled core 4, the location making rolled core 4 front end axial, radial is firm; And making coordinating more closely between the waterproof adventitia 4.1 at rolled core 4 front end place with tail sleeve pipe 5.1 inner cylinder face, leak preventing effect is better.The axial length of described front leak jacket 5 tail sleeve pipe 5.1 is greater than the diameter of rolled core 4, makes tail sleeve pipe 5.1 ensure connectivity and the anti-leakage of front leak jacket 5 with certain length.
The afterbody cover of described rolled core 4 has a rear leakage-proof cover 6, rear leakage-proof cover 6 comprises the cover body 6.1 be placed on rolled core 4 afterbody external cylindrical surface, is connected to the liquid storage cylinder for subsequent use 6.2 of cover body 6.1 rear end, the face of cylinder inwall of described cover body 6.1 coordinates with waterproof adventitia 4.1 external cylindrical surface and is socketed, and is provided with the low inside and high outside discontinuous spacing conical surface 6.11 on rear side of cover body 6.1 inwall.Its role is to: this discontinuous spacing conical surface 6.11 can very firmly coordinate with the rear end of rolled core 4, the location making rolled core 4 rear end axial, radial is firm.The axial length of this cover body 6.1 is greater than the diameter of rolled core 4, makes it with certain length, ensures connectivity and the anti-leakage of rear leakage-proof cover 6.The opening of described liquid storage cylinder for subsequent use 6.2 communicates with rolled core 4 rear end, and moving backward of rear leakage-proof cover 6 is spacing by cap cap 7, and moving forward by waterproof adventitia 4.1 rear end of rear leakage-proof cover 6 is spacing.
Be provided with on rear side of the inner cylinder face that described rear leakage-proof cover 6 overlaps body 6.1 and shrink type conical bench 6.6 and shrink shoulder hole 6.7, shrinking type conical bench 6.6 front end face coordinates spacing with waterproof adventitia 4.1 rear end, shrinking type conical bench 6.6 rear end face coordinates spacing with cap cap 7 front end, shrinks shoulder hole 6.7 inner chamber and forms liquid storage cylinder 6.2 for subsequent use.The effect of liquid storage cylinder 6.2 for subsequent use is that colored liquid can be back to absorbent material 4.2 in rolled core 4 rear end, and saving material does not waste.
In order to avoid loosening between tail sleeve pipe 5.1 and waterproof adventitia 4.1, simultaneously also in order to prevent the colored liquid in rolled core 4 from oozing out from side leakage between tail sleeve pipe 5.1 and waterproof adventitia 4.1, strengthen the stable connection of tail sleeve pipe 5.1 and waterproof adventitia 4.1.The scheme as shown in Figure 3 or Figure 4 that also can adopt further.
As shown in Figure 3, tail sleeve pipe 5.1 inwall of described front leak jacket 5 is provided with annular convex rib 5.4.
As shown in Figure 4, the shaft section of described front leak jacket 5 tail sleeve pipe 5.1 is trapezoidal, and the diameter of tail sleeve pipe 5.1 front end is corresponding with the diameter of rolled core 4 and closely cooperate, and tail sleeve pipe 5.1 point diameter is less than rear end diameter.
For firm rolled core 4 and the connectivity of rear leakage-proof cover 6, contribute to again simultaneously rolled core 2 inner circulate with outside gas unimpeded, described rear leakage-proof cover 6 can adopt scheme as shown in Figure 2 or Figure 3.
As shown in Figure 5, cover body 6.1 inwall of described rear leakage-proof cover 6 is provided with annular convex ring 6.4, two circle annular convex ring 6.4 parallel before and after two circles respectively has breach 6.5, two breach 6.5180 ° stagger and establish.Make the distance between two breach 6.5 reach farthest, leak preventing effect is better, simultaneously by the breach 6.5 between two circle annular convex rings 6.4, makes to be communicated with smoothness with rolled core 4 inside with outside gas.The program connects closely, and aeration is good.
As shown in Figure 6, with the perpendicular muscle 6.3 at thirty years of age, many intervals on cover body 6.1 inwall of described rear leakage-proof cover 6.Micro-interval between adjacent perpendicular muscle 6.3 can be formed and be communicated with the outside gas of rolled core 4.This scenario-frame is simple, and for processing technology, when especially adopting plastic material for rear leakage-proof cover 6, it is easy to process, is easy to realize.
More than just as enumerating, the present invention is not restricted to specific embodiment described above.Equalization conversion done without departing from the spirit and scope of the invention and amendment, should contain within the scope of the invention.
Adopting the watercolor pencil of the present invention program, even if all do not occur that the phenomenon of leakage occurs, effectively prevents the phenomenon of leakage when using and transport through test watercolor pencil front end and afterbody under placement in height, keeping watercolor pencil dry and comfortable, clean and tidy, attractive in appearance.Compared with now general watercolor pencil, service life can improve greatly, and can penholder 1 be made transparent, the outer bar changing rolled core watercolor pencil is all generally the unicity of real look, the aesthetics of watercolor pencil and polytropy are improved greatly, and its structure is simple, cost is low, be easy to production, safer in transport, storage, use.
