CN2443850Y - Telescopic ball pen - Google Patents

Abstract

The utility model relates to a telescopic ball pen, which can use liquid column ink and can be telescopic manually or automatically extended by pressing a button. When the collection is shortened, a pen cap cylinder can project and protect the pen point. A valve rod inside an ink tube simultaneously causes the valve to cover the ink pore of the pen point and an air pore. During writing, a hook pin hole is pressed; the hook pin hole can be automatically elongated and simultaneously close an ink groove, and an air pore and an ink pore can be opened to cause the ink to flow to the pen point for writing. Except a valve chamber type, the ink tube comprises the general liquid column pen with an expanding groove, the sign pen with absorbent cotton, and the general oil ball point pen with a pen core. A hollow pen cap drum can be replaced by using a pen cap drum of original patent technology, springs, and a sliding sleeve.

Description

Expansion ball pen

The utility model relates to a kind of improvement of telescopic ball-point pen, the expansion ball pen of external original patented technology, as speciallyying permit flat 2-57040 of communique and 4-87740 patent case in Japan December 3 nineteen ninety, refill for ball-point pen is oiliness slender type or Parker type, insertion is located in the front axle body inner canister, cap makes the nib of refill for ball-point pen the position occur by the work spring, and flexible operation is depressed pressure cylinder and made the hidden pen tip position of cap by the back axial region.The valuable space and the refill for ball-point pen heart of the flexible pen of its design waste is the common oiliness steel-ball pen heart, can't change the outfit just like the fluid column pen of fountain pen word formula.Gel ink pen pencil lead as changing the outfit reluctantly, the restriction of length during because of shortening, writing can not be permanent.And generally need two hand operateds when this elongation is write, if another portable thing or operating difficulties then when unclean.Not as elongation is convenient automatically.General in addition fluid column pen core all has expansion slot ink when preventing to be heated to overflow, and during collection all be the shaft of a writing brush down nib make air naturally up to expansion slot up, in order to the heat expansion exhaust, and cap covers the little rubber of Shi Youyi and can withstand a pin with anti-overflow.Because of no matter flexible pen is using and collecting, nib and ink and do not have cap and withstand nib down forever, thus during expanded by heating because of ink can be forced out from expansion slot earlier than air at nature down, very easily pollute clothes, so be not suitable for a flexible application.

The purpose of this utility model is to change that expansion ball pen becomes manually or the flexible biro of self-action, use flexible mechanism come by-pass valve control with the direction that lowers water column pressure and change the expansion exhaust with anti-pollution clothes.Because of the high event of space service efficiency integral body need chap and easier use.

The purpose of this utility model can be achieved through the following technical solutions:

As shown in Figure 1, can hold the partly hollow cap tube 2 of expansion slot 3 by one, be connected with one or a pair of push-and-pull rod 4 thereafter, the withdrawal of cap tube 2 when having spring 14 to keep writing behind the push-and-pull rod, and hold the stationary magazine creel 7 of ink barrel 9 and one or several shell slide cartridges 12 constitute with guide groove guiding crochet hook and push-and-pull rod.12 loose joints of shell slide cartridge have spring 13 and crochet hook 5 bulb 15 in case during shell slide cartridge 12 rotation not shadow to crochet hook 5 positions.Pressing shell slide cartridge 12 to overcome spring 13 when thumb shrinks to make and shortens; and compression is when the bottom; can press earlier push-and-pull rod 4 and overcome spring 14 and force cap tube 2 to stretch the protection nib, the rod of push-and-pull simultaneously 4 can pressure valve rods 17, make valve cover nib hole and airport as shown in Figure 4.Work is just like the effect of the sealing of the rubber in a general cap pin.Simultaneously open the valve upper end, makes the ink of ink container get off to mend the valve box and make the ink of using up.When shell slide cartridge 13 compression reached the bottom, self-action crochet hook 5 as shown in Figure 5 can hook an aperture of stationary magazine creel 7 and keep the compressive state of spring 13, if hand is then kept by magnetic force as shown in figure 14, so finishes the purpose that shortens collection.If will write the time, hand then both hands elongates, and self-action then places pen thumb forefinger middle interphalangeal, as writing posture, only firmly press the crochet hook hole with forefinger, crochet hook 5 breaks off relations naturally, the elastic force of spring 13 makes shell slide cartridge 12 normal length of rebounding.Because of shell slide cartridge 12 leaves push-and-pull rod 4, the elastic force of its spring 14 rebounds push-and-pull rod 4, drive 2 withdrawals of hollow cap tube and expose nib, the elastic force of spring 14 also pushes away valve rod 17 simultaneously, make the passage of valve closing ink container 8 and open logical nib in valve box 6 and airports, make the ink of valve box 6 flow to nib and write.Therefore motionless down in the former posture of hand, can write at once.Air is gone into valve box 6 by the ink duct breathing space when writing behind wireway 19 and valve box's expansion slot, replenish the volume of loss ink, and ink causes and writes circulation via writing owing to siphon principle diffuses to nib in the centre bore, just like common pen principle.If because of climate changes heat expansion, because of air nature in the ink container last, can prolong above the work ventilative so irrelevant the expanding with heat and contract with cold of expansion slot, the pressure weighing apparatus of keeping tie forever can not leak.After a small pipeline 19 leads to the ink duct ventilation, or directly exhaust is as shown in figure 12 by expansion slot for the vent cap of valve box 6.Space, additional valves chamber can expand to maximum as shown in figure 10, promoting valve can be promoted as shown in figure 14 as shown in figure 15 or by magnetic force by following promotion

For preventing that ink from leaking, ink barrel 9 also can be used a general fluid column expanded-type in it instead and be adopted as parallel connection type expansion slot in having used as shown in figure 16 to store the expansion ink.Because of flexible pen uses and collects, nib forever down thus can't as fluid column pen row be that air must turn around because of its collection, but still available long expansion slot prevents to leak.The new-type serially connected expansion slot of employing shown in Figure 17 is characterized by each and communicates for polyphone every lattice, i.e. the outlet of every lattice is the inlet of following lattice.So if before the ink that of expanding reclaims fully, air is had no chance and entered ink duct, so the available expansion slot of weak point prevents to leak.Vent cap can be directly after by expansion slot the below ventilation, or can lead to another expansion slot ventilation of top through a small pipeline 19 equally, make safer.

The absorbent wool formula that same ink barrel can be used known general signature pen pencil lead instead replaces.Because of absorbent wool takies partly space, so it is less to deposit the China ink amount, dress absorbent wools in the pipe 9 in the plastic cement as shown in figure 18, water jacket guides the path of crochet hook and pressure bar, and airport can be closed during contraction.Do not have the shaft of a writing brush of replacing formula as shown in figure 20, only with the path of two conduits 24 with guiding crochet hook and pressure bar, absorbent wool is placed directly in the stationary magazine creel.

Ink barrel is not considered as shown in figure 22 because of viscosity greatly then has to leak if use general neutral pencil lead or oiliness refill instead, dress ballpoint pen oil in the pipe 9 in the thick shape glue, the path of water jacket guiding crochet hook and pressure bar.Use as shown in figure 23 general thin type ball pen pencil lead and with the cover plate close-fitting, and with the path of conduit with guiding crochet hook and pressure bar.

This case cap tube can adopt the cap tube described in the flat 2-57040 of original patented technology Japan in 3 days December nineteen ninety special permission communique as shown in figure 24 by cap tube 28 if sacrifice the interior space of hollow cap tube in addition, and spring 29 and sliding sleeve 27 replace.
