Chip fixed frame, chip assembly, Delevoping cartridge and developing apparatus
Technical field
The utility model relates to chip fixed frame, chip assembly, Delevoping cartridge and developing apparatus.
Background technology
At present, known developing apparatus, generally comprises Delevoping cartridge and chip assembly, and Delevoping cartridge comprises box body and is arranged on charhing unit, photosensitive unit, developing cell, the cleaning unit in box body and on box body, and chip assembly comprises chip and chip fixed frame.See Fig. 1, Fig. 2, chip 2 is arranged on chip fixed frame 3, the both sides of the edge 301 of chip fixed frame 3 can realize locating completely to chip 2 in conjunction with rear wall 304 and front side locking buckle 302, make there is the position relatively determined between chip 2 and chip fixed frame 3.The chip fixed frame 3 that chip 2 is housed is inserted on box body 1, fitted by the wedge locating block 303 of a pair symmetry in chip fixed frame 3 both sides and the locating slot 102 on box body 1 surface, chip fixed frame 3 enters along direction of insertion, locking buckle 302 on it and the locking mouth 101 of box body 1 coordinate, so just the chip fixed frame 3 being equipped with chip 2 is fixed on box body 1, as shown in Figure 3.Locking buckle 302 as we can see from the figure on chip fixed frame 3 designs front end in the middle of the below of chip placement 2, if want like this to take off chip fixed frame 3 from box body 1, need to make locking buckle 302 on chip fixed frame 3 to intermediate deformation with hand or instrument, it is made to exit locking mouth 101 on box body 1, because locking hasp 302 is very little, its surrounding space is also narrow, operates very inconvenient, affects work efficiency.But install at chip, change and reprocess in operation, keep away again unavoidable dismounting chip fixed frame.
Therefore, people can be separated with box body desirable to provide a chip fixed frame that can not only make, and chip can also be made installing, change and reprocess the developing apparatus of operation chips fixed frame also easy disassembly.

A kind of chip assembly, comprise chip and chip fixed frame, described chip fixed frame is above-mentioned chip fixed frame.
The two ends of described chip are provided with projection, and described projection comprises two sides.A side in two sides of described projection is a side in two sides of the chip that the folding surface arranged with described chip fixed part rear end abuts.
A kind of Delevoping cartridge used with said chip component matching, comprise: box body, the surface of described box body is provided with chip assembly installation portion, the both sides of described chip assembly installation portion are respectively provided with sidewall, described sidewall top has extended internally brace table, described sidewall and brace table form the attachment rail that described chip fixed frame mates with described installation guide part, the limited block with another contacts side surfaces in two of described chip sides is provided with above described brace table, described limited block extends along the direction that described attachment rail extends, the rear of corresponding described limited block and being positioned to be provided with two of mating with two button bit portions and to lock mouth inside box body.
The attachment rail cross section Cheng “ ╔ respectively of described both sides " with “ ╗ " shape.
A kind of developing apparatus, comprise chip assembly and Delevoping cartridge, described chip assembly is chip assembly as above, and described Delevoping cartridge is Delevoping cartridge as above.
After have employed technique scheme, chip fixed frame can not only be made can be separated with box body, chip can also be made in installation, change and reprocess the also easy disassembly of operation chips fixed frame.Solving existing chip fixed frame, chip assembly, Delevoping cartridge and developing apparatus can not only make chip fixed frame can be separated with box body, chip can also be made installing, change and reprocess the technical matters of operation chips fixed frame also easy disassembly.

Embodiment
As illustrated in figures 4-5, developing apparatus 10 comprises Delevoping cartridge and chip assembly 12.Delevoping cartridge comprises box body 11, and the surface of box body 11 is provided with chip assembly installation portion 13.Chip assembly 12 comprises: chip fixed frame 14 and chip 15, the two ends of its chips 15 are with projection 151, and projection 151 comprises two sides (1511,1512), indicate at this, chip coordinates with chip fixed frame, and wherein chip structure also can have other form.
See Fig. 6, the both sides of chip assembly installation portion 13 are respectively provided with sidewall 131, sidewall 131 top has extended internally brace table 132, “ ╔ is Chenged in the cross section of sidewall 131 and brace table 132 " with “ ╗ " shape, form the attachment rail 1311 of chip fixed frame 14, above brace table 132 be and chip projection 151 limited block that side 1511 contacts 133, limited block 133 extends along direction that attachment rail 1311 extends, the rear of corresponding limited block 133 and be positioned at inside box body and have two to lock mouths 134.
As shown in Figure 7, chip fixed frame 14 comprises: main body 140, the installation guide part 141 set gradually from top to bottom with both sides, corresponding main body 140 front end, chip fixed part 142, elastic arm 143 and the button bit portion 144 arranged along elastic arm 143 end, wherein button bit portion 144 top chamfer, forms back-off.
Here specifically describes the process that chip assembly 12 is assembled on chip assembly installation portion 13.
Composition graphs 4-7, first being faced up by chip 15 is placed on chip supporting table 132, chip projection 151 side 1511 is made to be connected on the end face of limited block 133, then chip fixed frame 14, allow the installation guide part 141 of chip fixed frame 14 advance along the attachment rail 1311 of chip assembly installation portion 13 put in place, now the another side 1512 of chip projection 151 abuts with the folding surface 1421 of chip fixed part 142 rear end, simultaneously along with button bit portion 144 enters two the locking mouths 134 be arranged in inside box body, elastic arm 143 can be subject to downward extruding, be inconjunction with chip fixed part 142 and can extrude chip 15 two ends, below the location completely to chip 15 is just achieved, and chip fixed frame 14 is located completely because the restriction of attachment rail 1311 and the locking of locking mouth 134 also achieve, so chip assembly 12 is just reliably assembled on chip assembly installation portion 13.
When chip 15 pulled down by needs, two finger appropriateness press the elastic arm 143 on chip fixed frame 14 downwards, and apply a urgent thrust backward simultaneously, the button bit portion 144 of such elastic arm 143 front end is just easy to withdraw from the locking mouth 134 inside box body, the attachment rail 1311 continued again along chip assembly installation portion 13 exits chip fixed frame 14, constraint release then on chip 15, just can take off chip 15.
To sum up, achieve chip fixed frame by technical solutions of the utility model to be separated with box body, but also make chip install, change and reprocess operation chips fixed frame easy accessibility, reach in background technology to be solved about chip installation, change and reprocess in operation, dismounting chip fixed frame gets the trouble of chip.
