[specific embodiment]
With specific embodiment the present invention is done to set forth further with reference to the accompanying drawings below.
As shown in Figure 1 and Figure 2, rolling curtain powder metallurgical piece locking device comprises the carriage 1 that is provided with pearl axle 11 and cavity 12, pelletron wheel 2, fixture 3, holds limit spring 4 and actuator 5 tightly.
Wherein, pearl axle 11 by under a part be hexagonal cylinder 111, be cylinder 112 by a last part, and latter's diameter is less than the former, it also is provided with a groove topmost.Fixture 3 is a metallic sintered products, is shaped as cylindrically, and its center is provided with and described hexagonal cylinder 111 corresponding hexagonal through holes 31, and its periphery top is provided with flange 32, as shown in Figure 3, Figure 4.Hold limit spring 4 tightly by making.Hold limit spring 4 tightly and make by a manganese steel wire winding, outwardly-bent formation two hook portions 41 in described two ends wiry, its cross section becomes " Ω " shape, as Fig. 5, shown in Figure 6.The excircle of pelletron wheel 2 is provided with raceway 21 and the upper and lower catch 22 for the pelletron location, and its outside diameter is littler than the diameter of described cavity 12, and circle is provided with a block 23 that protrudes in it, and interior circular diameter is bigger than the diameter of holding limit spring 4 tightly, and is littler than hook portion 41.The position that the positive and negative two sides of pelletron wheel 2 is positioned at block 23 the right respectively is provided with a concave station 24, can be interlocked with described hook portion 41 of holding limit spring 4 tightly.Actuator 5 middle parts are provided with and described cylinder 112 corresponding through holes, and its underpart is provided with one and is used to insert the boss 51 of holding space between limit spring 4 and the pelletron wheel 2 tightly, and its top is provided with one and is used for the connector 52 that links to each other with the roller shutter reel.
During installation, will hold limit spring 4 earlier tightly and tightly be sleeved on the fixture 3, two hook portions 41 will holding limit spring 4 then tightly are fastened on respectively on two concave stations 24 on the pelletron wheel 2.Then pelletron is enclosed within on the raceway 21 between the upper and lower catch 22 on the pelletron wheel 2, the two ends of pelletron pass the backguy hole from carriage 1 respectively, these three assemblies are enclosed within on the hexagonal cylinder 111 on the pearl axle 11, this moment, these three assemblies all were placed in the cavity 12 just again.At last actuator 5 is enclosed within cylinder 112 parts of pearl axle 11, simultaneously its boss 51 inserts and holds tightly between limit spring 4 and the pelletron wheel 2 in the space, and this moment, the groove of pearl axle 11 the tops was exposed at the outside of actuator 5 just.At last, a fixing spring is snapped on the groove and actuator 5 of above-mentioned pearl axle 11, play the fixedly function of all component.Wherein, when placing fixture 3, flange 32 has upwards guaranteed to hold tightly limit spring 4 and can not skid off fixture 3.
In real work, the connector 52 on the actuator 5 links to each other with the reel of curtain.When the pulling pelletron, pelletron drives 2 rotations of pelletron wheel, pelletron is taken turns the block 23 on 2 or is pushed away the hook portion 41 on the left side of holding limit spring 4 among Fig. 5 tightly left, or push away the hook portion 41 on the right of holding limit spring 4 among Fig. 5 tightly to the right, cause holding tightly limit spring 4 and become big, the power of holding tightly of fixture 3 is reduced, can be around fixture 3 rotations.Drive actuator 5 rotations again, actuator 5 drives the rotation of curtain reel again, finishes the rising of curtain or the action of decline.When stopping drag pelletron, block 23 stops the promotion to hook portion 41, holds limit spring 4 tightly and recovers original state, tightly embraces fixture 3, reaches spacing purpose.
In the preferred embodiment of the present invention, used fixture 3 adopts the metallurgical part of copper-iron-based powder, and its content is: copper 10%, iron surplus 89.2%, carbon 0.8%.Metallurgical part wear resistance of this copper-iron-based powder and intensity are all very good.Operation is: depanning, be pressed into required external form with powdered metallurgical material, and put it into the agglomerating furnace sintering then, after calcining is good, it is cooled off naturally, putting into deep fat at last soaks, and guarantees that fully metallic sintered products can oxidation.
The method of making rolling curtain powder metallurgical piece locking device comprises step:
The first, to be immersed in temperature be in 40 degrees centigrade the deep fat with the limit spring 4 of holding tightly made, soaked two hours; The main component of described deep fat is a machine oil.
The second, take out the limit spring 4 of holding tightly that soaks and be sleeved on the metallic sintered products 3.Because the effect of expanding with heat and contract with cold can become greatly slightly through the diameter of holding limit spring 4 tightly that soaks, and can be sleeved on the metallic sintered products 3.
The 3rd, cooling naturally.Naturally after the cooling, hold limit spring 4 tightly and resile, tightly embrace metallic sintered products 3.
Following table is the contrast effect table through employing powder metallurgical piece locking device after experimental results show that and employing common plastics transmission mechanism:
| Project | Application life (year) | Continuous operating time (minute) |
| Powder metallurgical piece locking device | ??????10 | ???????????30 |
| The common plastics transmission mechanism | ??????1 | ???????????1 |
In another preferred embodiment of the present invention, used fixture 3 adopts the metallurgical part of copper-iron-based powder, and its content is: copper 7%, iron surplus 92.2%, carbon 0.8%.Holding limit spring 4 tightly will soak in 50 degrees centigrade deep fat and got final product in one hour.
In another preferred embodiment of the present invention, fixture 3 adopts copper-base powder metallurgy spare, and its content is: tin 10%, lead 2%, zinc 0.8%, copper surplus.Advantage is that running-in ability is good, low friction moment, but intensity is not high.
In another preferred embodiment of the present invention, fixture 3 adopts iron-base sintered metal pieces, and its content is: copper 2%, tin 3%, carbon is less than 0.9%, iron surplus.This kind metallic sintered products is a kind of Standard of applied range, generally is used on micromachine, washing machine and the sewing machine, and strength ratio is higher.
In sum, rise continually and the decline curtain all can make and holds limit spring 4 tightly constantly around fixture 3 rotation,, be worn easily or damage easily, will cause curtain to use if fixture 3 is solid inadequately.The present invention has been owing to adopted the metallic sintered products of high holding capacity, the high abrasion part 3 that fixes, make curtain the hinge position very firmly, guaranteed the application life of curtain.Simultaneously, because metallic sintered products has the advantage of self oil-containing, low noise, the noise when having reduced the pulling pelletron.Have extraordinary market prospects.
