Description

Print cartridge protection member

Technical field

The utility model relates to a kind of print cartridge protection member.

Background technology

In ink jet printing device, use the technology of detachable print cartridge early well known.Known print cartridge generally includes the box body that a bottom has ink outlet port, and box body generally adopts corrosion resistant plastics to make, and its inside accommodates ink.For prevent store, the transportation ink inside through ink outlet port reveal, evaporation, and exterior materials stops up or enters ink outlet port, needs usually carry out effective peelable formula sealing to ink outlet port.

One of existing encapsulating method is that print cartridge is removably mounted on the print cartridge protection member, utilizes frame for movement to exerting pressure as elastic foam, sponge block, silicon rubber piece elastomeric material, thus ink outlet port pressurization or the application of force is formed sealing.

Fig. 1 illustrates a kind of common print cartridge protection member B ', it comprise an orthogonal diapire 21 ' and sidewall 22 ', between the two by a stiffener 23 ' support.Sidewall 22 ' on also be provided with the angular flexibility 221 that Convenient ink box installs '.Angular flexibility 221 ' above, sidewall 22 ' be provided with extend arm 24 ', extend arm 24 ' basically and diapire 21 ' parallel and extend in the same way, its free end curve inwardly downwards form a stationary jaw 241 '.The diapire 21 of print cartridge protection member B ' ' on also be provided with the elastomer (not shown).The diapire 21 of print cartridge protection member B ' ', sidewall 22 ' and the stiffener 23 ' framework that can hold print cartridge of formation; in the time of in print cartridge is installed to it; extend arm 24 ' claw 241 ' can be buckled on the projection at print cartridge top; thereby print cartridge is fixed in the print cartridge protection member B '; this moment, elastomer just in time was against the ink outlet port place of print cartridge, the sealing ink outlet port.But the stiffener 23 of this print cartridge protection member B ' ' too small; its height H be lower than angular flexibility 221 on the sidewall ' height h '; therefore print cartridge protection member B ' easily deforms; especially with angular flexibility 221 ' sidewall 22 ' outwardly-bent easily; make print cartridge in the interior run-off the straight of print cartridge protection member B '; print cartridge is got loose from print cartridge protection member B ', thereby cause ink leakage, pollute surrounding environment.

The utility model content

The utility model purpose provides a kind of on-deformable print cartridge protection member.

For achieving the above object, the utility model provides following technical scheme: print cartridge protection member, print cartridge removably is installed on it, this print cartridge comprises that an inside holds the box body of ink, the bottom of box body is provided with ink outlet port, and the top is provided with locating lug, and print cartridge protection member comprises: diapire; Sidewall perpendicular to diapire, which is provided with angular flexibility; Stiffener connects and supporting side walls and diapire, and it is perpendicular to diapire and sidewall; Extend arm, be located at the top of angular flexibility, the direction parallel with diapire from the sidewall upper edge extended, and its free end curves inwardly downwards and forms a stationary jaw, and wherein, the height of stiffener is higher than the height of angular flexibility.

Print cartridge protection member with said structure is because of the height of stiffener is higher than the height of angular flexibility on the sidewall, so improved the non-deformability of print cartridge protection member, especially sidewall.Therefore can effectively prevent print cartridge run-off the straight or from print cartridge protection member, get loose in print cartridge protection member, avoid ink leakage.

Scheme is to establish a spacing rib on adjutage preferably, and it can react on the locating lug at print cartridge top with claw one, guarantees the accurate location of print cartridge in print cartridge protection member, prevents that print cartridge from moving.

Description of drawings

Fig. 1 is the structural representation of print cartridge protection member in the prior art;

Fig. 2 is the structural representation of the utility model print cartridge protection member behind the installation print cartridge

Fig. 3 is the structural representation of the utility model print cartridge protection member.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.

The specific embodiment

In conjunction with referring to Fig. 2 and Fig. 3, print cartridge A is removably mounted among the print cartridge protection member B.Wherein print cartridge A comprises that an inside holds the box body 1 of ink, and box body 1 top is provided with locating lug 11, and box body 1 bottom is stepped, forms convex 12, and the ink outlet port (not shown) just is located on the convex 12.Print cartridge protection member 2 is essentially a framework; comprise an orthogonal diapire 21 and a sidewall 22, connect and support the stiffener 23 of diapire 21 and sidewall 22, wherein; stiffener 23 is positioned at the side of print cartridge protection member B, is provided with perpendicular to diapire 21 and sidewall 22.The bottom of diapire 21 corresponding print cartridge A is provided with, and the ink outlet port place of its corresponding print cartridge A is equipped with an elastomer (not shown), and when print cartridge A was mounted on the print cartridge protection member B, this elastomer can just in time be against the ink outlet port place of print cartridge A.Be provided with angular flexibility 221 on sidewall 22, this angular flexibility 221 can make sidewall 22 have certain elasticity, with the installation of Convenient ink box A.Above angular flexibility 221; extend one from sidewall 22 upper edges and diapire 21 parallel directions and extend arm 24; the free end that extends arm 24 curves inwardly downwards and forms a stationary jaw 241; when print cartridge A is installed on the print cartridge protection member B; this claw 241 can be buckled on the locating lug 11 at print cartridge A top; thereby print cartridge A is fixed in the print cartridge protection member B, prevents that it from getting loose.

The stiffener 23 of print cartridge protection member B has a height H, and angular flexibility 221 is h apart from the height of diapire 21, and in the utility model, the height H of stiffener 23 is higher than the height h of angular flexibility 221.Be compared to print cartridge protection member of the prior art, the height H of the stiffener 23 of the utility model print cartridge protection member B has increased, and its enabling capabilities to diapire 21 and sidewall 22 is strengthened, and has improved the non-deformability of print cartridge protection member B.In addition; the height h that is higher than angular flexibility 221 because of the height H of stiffener 23; in the strain of sidewall 22 can be controlled in to a certain degree, can not cause print cartridge A run-off the straight or from print cartridge protection member B, get loose in print cartridge protection member B, effectively avoid ink leakage.

Between claw 241 and sidewall 22, extend arm 24 and also be provided with a spacing rib 242.Interval between spacing rib 242 and the claw 241 adapts with the locating lug 11 at print cartridge A top; in other words; when print cartridge A is mounted on the print cartridge protection member B; the locating lug 11 at print cartridge A top just in time embeds in the interval between spacing rib 242 and the claw 241; not only guaranteed the accurate location of print cartridge A in print cartridge protection member B, can prevent that also print cartridge A from moving on the direction parallel with diapire 21.

On the diapire 21 of print cartridge protection member B, also be provided with latch protrusion 25; when print cartridge A is mounted on the print cartridge protection member B; latch protrusion 25 just in time is stuck in the sidepiece of the convex 12 of print cartridge A bottom, print cartridge A can be locked among the print cartridge protection member B, prevents that print cartridge A from getting loose.
