Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail. Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.

First, such as Fig. 1, this utility model Delevoping cartridge includes: Delevoping cartridge 1, and the rotatable support in its one end has developer roll 2, is formed with mounting groove 3 in the side relative with above-mentioned developer roll 2, and locking component 4 is installed in above-mentioned mounting groove 3.

As in figure 2 it is shown, on the framework of Delevoping cartridge 1, one side is formed between above-mentioned developer roll 2 and above-mentioned installation groove 3, is formed with a projection 6 and catch 5 on above-mentioned side. Locking component 4 is installed on above-mentioned projection 6 and installs in groove 3. Concrete, locking component 4 is configured to torsion spring, and it has a center of rotation 4a; Limiting unit 4b stretches out towards above-mentioned center of rotation 4a at a circular arc place of center of rotation 4a, to limit the locking component 4 direction of rotation along its center of rotation 4a; Cantilever arm 4c stretches out towards above-mentioned center of rotation 4a at another circular arc place of center of rotation 4a, and above-mentioned end bend outside for cantilever arm 4c forms turning point 4d; Meshing arm 4e connects above-mentioned turning point 4d and extends from above-mentioned turning point 4d, and the end bend of above-mentioned meshing arm 4d forms bending section 4f, leading arm 4g and connects above-mentioned bending section 4f and extend from above-mentioned bending section 4f; Above-mentioned cantilever arm 4c, turning point 4d, meshing arm 4e, bending section 4d, leading arm 4g are configured to the abutting part of locking component 4, when Delevoping cartridge 1 is mounted to bulging box 7(as shown in Figure 4) in, above-mentioned abutting part receives the external force generation elastic deformation of drum box 7 and locks above-mentioned Delevoping cartridge 1 to above-mentioned bulging box 7.When installing above-mentioned locking component 4, its center of rotation 4a is inserted in above-mentioned projection 6, and its limiting unit 4b is resisted against on above-mentioned catch 5, a part of cantilever arm 4c snaps in mounting groove 3, a part of leading arm 4g also snaps in mounting groove 3, so, completes the installation of locking component 4.

As shown in Figure 3 and Figure 4, be respectively Delevoping cartridge 1 locking device partial structurtes schematic diagram and drum box 7 structural representation. Illustrate in order to convenient, the Delevoping cartridge 1 in Fig. 3 eliminates the structure such as side cover and gear. Supporting on the framework of drum box 7 and have photosensitive drums 8, the two side ends in said frame is provided with guide rail 9, and drum box 7 is provided with limit wall 10 in the side relative with photosensitive drums 8, and the side of photosensitive drums 8 is formed porose or groove (not shown) by described limit wall 10 above. Delevoping cartridge 1 can be mounted in bulging box 7 along above-mentioned guide rail 9. Delevoping cartridge 1 is dismountable to be mounted in bulging box 7, and its relatively above-mentioned bulging box 7 is movable to 3 positions: outer fix, and in this outer fix, Delevoping cartridge 1 separates with drum box 7, is that Delevoping cartridge 1 is moved adjacent to drum box 7 and prepares the preparation installation site installed along guide rail 9; Latched position, in this latched position, Delevoping cartridge 1 is mounted to completely in bulging box 7 and is locked in above-mentioned bulging box 7, and the concrete structure being locked in bulging box 7 about Delevoping cartridge 1 will be described; Intermediate mounting position, it it is Delevoping cartridge 1 intermediate mounting position along the motor process of guide rail 9 when being mounted to bulging box 7, at this intermediate mounting position, Delevoping cartridge 1 movement in assembly direction can move to latched position, and Delevoping cartridge 1 can move to outer fix along moving with installation direction opposite direction.

When installing Delevoping cartridge 1 to when rousing in box 7, the leading arm 4g being positioned at abutting part end on locking component 4 is oppressed by the limit wall 10 rousing box 7, abutting part is pressed so that locking component 4 has along its center of rotation 4a trend rotated, limiting unit 4b is resisted against the rotation of washer 5 upper limit locking component 4, leading arm 4g by above-mentioned make abutting part generation elastic deformation by pressure and enter the limit wall 10 of bulging box 7 in. above-mentioned abutting part also includes an engaging piece, this engaging piece is by meshing arm 4d, bending section 4f and leading arm 4g is constituted, it is configured to highlight from Delevoping cartridge frame table towards the lateral direction of Delevoping cartridge framework, when Delevoping cartridge 1 moves along guide rail 9 and is finally mounted to completely in bulging box 7, namely when the relatively bulging box 7 of above-mentioned Delevoping cartridge 1 moves to latched position, above-mentioned engaging piece is configured to relative with the hole on above-mentioned limit wall 10 or groove, above-mentioned abutting part is the hole on above-mentioned limit wall 10 faced by its engaging piece or groove when latched position, locking component 4 recovers elasticity and makes above-mentioned engaging piece snap in above described holes or groove, the at least contact internal walls of a part for engaging piece and above described holes or groove, so complete Delevoping cartridge 1 and the locking of drum box 7. when Delevoping cartridge 1 dismantled by needs, it is only necessary to catch the handle being arranged on Delevoping cartridge 1 upwards to choose, locking component 4 can produce elastic deformation and departs from above described holes or groove and depart from from drum box 7.

It is a preferred version that locking component is set in the present embodiment torsion spring, certainly may be used without other such as elastic sheet metals, and Elastic plastic-rubber sheet etc. has elastic component and can reach the effect of locking component in the present embodiment too; The hole snapped in bulging box on the wall of limit by locking component or groove are also preferred versions, it is also possible to what snap in all the other places on bulging box framework has in hole or groove, equally can reach the effect of locking Delevoping cartridge; In the present embodiment, the elastic deformation of locking component utilizes leading arm to be roused box pressing and lead in locking component entrance drum box, above-mentioned be constructed to so that the card access point of elastic component more mellow and fuller thus can reduce its for drum box sidewall scratch, owing to locking component itself has elasticity, it can also cancel leading arm, directly adopts meshing arm to be roused box limit wall by compressive strain the structure snapping in hole corresponding on bulging box or depressed part. In a word, owing to locking component itself is made up of elastic material, when Delevoping cartridge is mounted on bulging box, on locking component, abutting part can receive the power of bulging box applying thus producing locking and the unblock that deformation completes Delevoping cartridge and rouses box, can do various deformation for those skilled in the art without departing from scope of the present utility model when.

The locking device of the Delevoping cartridge in the present embodiment, easy to operate, simple in construction, solve the lock-out state needing manually to release Delevoping cartridge in prior art and the locking baroque technical problem of parts.

Above example only in order to the technical solution of the utility model to be described, is not intended to limit; Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
