A kind of cistern water-discharging is pulled knob
Technical field
The utility model relates to a kind of cistern water-discharging and pulls knob, is specially adapted to utilize the difference of pulling stroke when knob is forward and reverse to be reversed to reach the knob of pulling of the double water of control water tank.
Background technology
The hand that existing cistern water-discharging is pulled knob is pulled with drive link and is mostly one-body molded, drive link curves certain angle, and to penetrate installation very inconvenient for the buttonhole of pulling from the water tank, also needs a lot of component of dismounting when dismantling equally, and increased the volume of whole transmission mechanism, installation is difficult and consumptive material is bigger.
The utility model content
The utility model is for overcoming above deficiency, propose a kind of outside drive link socket one spiral shell head, can be directly and transmission mechanism plugs together and knob is pulled in fastening draining.
The utility model is finished like this: a kind of cistern water-discharging is pulled knob, contains hand and pulls, and drive link and transmission rope, hand are pulled with drive link and be connected; Pull knob and be provided with spiral shell head and transmission mechanism, the spiral shell head is pulled with hand and is connected, and is sheathed on the drive link outside; It is characterized in that transmission mechanism by shell, be located at plugging together or engaging the clamp ring of coupling, the rolling disc that is connected with drive link, connecting rod, guide pad and reset tension spring with the spiral shell head and form on the shell; The connecting rod two ends flexibly connect with rolling disc and guide pad respectively; The reset tension spring two ends are individually fixed on guide pad and the shell; Transmission rope one end is fixed on the guide pad.
For realizing that the utility model is applied to double water tank, can be inside the shell wherein on one side, near rolling disc, establish half row's positive stop, reach the difference of utilizing stroke when pulling that knob is forward and reverse to be changeed with the restriction hand torsional amplitude of pulling, thereby reach the double water of control water tank.Arrange partly that positive stop also can be located at that hand is pulled and the spiral shell head between.
The utility model compact conformation, design science need only plug together or engage the clamp ring of transmission mechanism with spiral shell head and drive link during installation by jack, and tighten and get final product.Promptly make things convenient for installation or removal, save material again, and be applicable to single or double water tank, improve suitability greatly water tank.

Among the figure: 1. hand is pulled engaging boss in 15. clamp rings of 2. drive links, 3. spiral shell heads, 4. latches, 5. clamp rings, 6. outer casing upper cover plates, 7. connecting rods, 8. rolling discs, 9. guide pads, 10. reset tension springs, 11. shell lower covers, 12. transmission ropes, 13. half row's positive stops, 14. drive links engaging boss
The specific embodiment mode
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 2, each accessory of the utility model is assembled into overall diagram as Fig. 1 successively.The buttonhole of pulling outside water tank inserts with spiral shell head 3 and drive link 2 during installation, and whole transmission mechanism places the correspondence position in the water tank, and the two plugs together or engages, and tightens fastening spiro loop 5 and gets final product.Spiral shell head 3 plugs together as shown in Figure 2 with clamp ring 5; Spiral shell head 3 engages as shown in Figure 6 with clamp ring 5, tightens after spiral shell head 3 inserts to make boss 14 and boss 15 engage fastening.
As Fig. 3, drive link 2 flexibly connects (plugging together) with rolling disc 8, and an end of connecting rod 7 is connected with rolling disc 8, and the other end is connected with guide pad 9, and guide pad is located on the interior guide rail of shell, but easy on and off moves.Reset tension spring 10 1 ends are fixed on the shell, and the other end is fixed on the guide pad 9, and transmission rope 12 1 ends are fixed on the guide pad 10, and the other end connects the valve body opening mechanism of water tank.Rotate hand to the left or to the right and pull 1 and can pass through drive link 2 successively, rolling disc 8 and connecting rod 7 drive guide pads 9 and move upward, thereby drive transmission rope 12 pulling valve body opening mechanisms, with the control draining.After the relieving hand pulled 1, reset tension spring 10 can reset hand slope 1 by guide pad 9, connecting rod 7, rolling disc 8 and drive link 2.
As Fig. 4, rotate counterclockwise hand and pull 1 and can drive guide pad 9 and transmission rope 12 whole process are mentioned, make full seniority among brothers and sisters Cheng Yundong thereby drive water tank valve body opening mechanism, reach full row's effect.
As Fig. 5, clockwise rotate hand and pull 1, because rolling disc 8 is subjected to the effect of half row's positive stop 13, only can rise to the stroke shorter than full seniority among brothers and sisters journey, partly rank Cheng Yundong thereby drive water tank valve body opening mechanism, reach half row's effect.
The utility model pulls 1 if do not establish half row's positive stop 13 no matter pull hand forward or backwards, all can play single effect.Because the utility model compact conformation, simple installation is applicable to single or double water tank, has improved the suitability of the utility model to various water tanks greatly.
