In the present embodiment, described retracting device is be fixed in the weight 2 outside described draw-tube 1, and this weight 2 is matched with below described self-locking module.Except this, described retracting device also can adopt other parts, and such as back-moving spring, balancing weight etc. replace.
In the present embodiment, as shown in Figure 1 and Figure 2, an outlet terminal is connected on described draw-tube 1 top, and this outlet terminal is specially pull gondola water faucet 6.The utility model also comprises one for shelving the base 7 of pull gondola water faucet 6, and this base 7 has the bit port that allows supplying described draw-tube 1 to pass.During installation, the water flow switch 8 of described base 7 and pull gondola water faucet 6 is installed on the table top 9 of a washbasin or tank, and pull gondola water faucet 6 is connected in one end of described draw-tube 1, and the other end connects the water flow switch of pull gondola water faucet 6.Also be provided with a fixed fitting 10 immediately below the corresponding described base 7 of table top 9, the upper shell 31 of described fixed body can be connected to this fixed fitting 10.
A kind of drawing device with auto-lock function of the present utility model, its original state as Figure 8-Figure 10, now, pull gondola water faucet 6 is held on base 7, the clutch shaft bearing 43 of two friction module 4 is positioned at the lowermost end position of the guide frame 33 of fixed body 3, each snap component 5 is in released state, namely one end of fork 51 is mounted on the first mounting part 5411 of the first rail groove 541 of movable part 54, has certain distance between two spline axles 544 of movable part 54 and the rotating shaft 42 of the friction pulley above it 41.
When user is pulled upwardly pull gondola water faucet 6 and drives draw-tube 1 to rise, owing to there is frictional force between two friction module 4 and draw-tube 1, thus two friction module 4 rise thereupon, and when friction module 4 move upward put in place time, under the effect of clutch shaft bearing 43, draw-tube 1 can continue to rise, and drives the friction pulley 41 of each friction module 4 and rotating shaft 42 thereof to rotate.Along with the ascending motion of friction module 4, adopt the coupled movable part 54 of stay cord 45 also to rise thereupon, and Compress Spring 55, fork 51 swings simultaneously.When staff decontrols pull gondola water faucet 6, when stopping promoting draw-tube 1, draw-tube 1 can decline a little under the Action of Gravity Field of weight 2, and two friction module 4 also decline certain height thereupon; The movable part 54 of each snap component also to decline certain height a little by the restoring force effect of spring 55, and the other end 512 of fork 51 is finally mounted on the second mounting part 5421 of the second rail groove 542, now, movable part 54 is compared original state and is risen to latched position, and locked by described buckle structure, avoid movable part 54 to decline.Movable part 54 is when latched position, and its spline axle 544 just withstands the rotating shaft 42 of the friction pulley 41 above it, limits each friction pulley 41 and declines and rotate, thus makes two friction pulleys 41 block draw-tube 1, as shown in Figure 14, Figure 15.Thus, draw-tube 1 can be held in the state after pull by after pull, liberates the both hands of user with this, makes user's in use more light and convenient.
When draw-tube 1 regained by needs, user only needs pull-up pull gondola water faucet 6 again, and drive draw-tube 1 to rise, make the movable part 54 of two friction module 4 and each snap component increase, fork 51 swings thereupon thereupon.When staff decontrols pull gondola water faucet, by the effect of spring 55 restoring force, one end of fork 51 is finally mounted on the first mounting part 5411 of the first rail groove 541, and now, movable part 54 drops to unlocked position, and is held in unlocked position by described buckle structure; Movable part 54 is when unlocked position, and its spline axle 544 cannot touch the rotating shaft 42 of friction pulley 41, thus removes the restriction to friction pulley 41, makes friction pulley 41 can recover to decline and rotate.Under the Action of Gravity Field of weight 2, draw-tube 1 and two friction module 4 fall after rise respectively, finally return to original state as shown in Figure 9, Figure 10.
The two ends 511,512 of the described fork motion state in the first rail groove 541 and the second rail groove 542 is as shown in Figure 16, Figure 17: the little figure of a of Figure 16 and Figure 17 is respectively original state, also be released state, now, one end 511 of fork is mounted on the first mounting part 5411 of the first rail groove 541 of movable part 54, and the other end 512 of fork is resisted against the top of the second rail groove 542.
When draw-tube 1 be drawn upwardly draw time, the movable part 54 of each friction module 4 and each snap component rises thereupon, and the other end 512 of fork moves to the medium position on the left of the second rail groove 542 along the guide wall 5422 of the second rail groove 542, shown in the little figure of b as Figure 17, one end 511 of fork moves to the medium position on the right side of the first rail groove 541 thereupon, shown in the little figure of the b as Figure 16.Along with movable part 54 continues to rise, one end 511 of fork moves to the right side minimum point of the first rail groove 541 along the guide wall 5412 of the first rail groove 541, shown in the little figure of c as Figure 16, the other end 512 of fork also corresponding sports to the left-of-center position, bottom of the second rail groove 542, shown in the little figure of the c as Figure 17.When people lets go, under the restoring force effect of spring 55, the other end 512 of fork moves along the spigot surface 5423 of the second rail groove 542, and be finally mounted on the second mounting part 5421 of the second rail groove 542, shown in the little figure of d as Figure 17, this is lock-out state, and movable part cannot continue to move downward, and limiting friction wheel 41 declines and rotates, thus block draw-tube 1.Now, one end 511 of fork moves to left-of-center position bottom the first rail groove 541 inner circumferential cell wall, shown in the little figure of the d as Figure 16.
When draw-tube 1 regained by needs, draw-tube 1 is by upwards pull again, the movable part 54 of each friction module 4 and each snap component rises thereupon, move along the guide wall 5413 of the first rail groove 541 in one end 511 of fork thereupon, and move to the left side minimum point of the first rail groove 541, shown in the little figure of the e as Figure 16.Now, the other end 512 of fork also corresponding sports to the bottom right side of the second rail groove 542, shown in the little figure of the e as Figure 17.When people lets go, under the restoring force effect of spring 55, movable part 54 declines certain height, to be moved the first mounting part 5411 along the guide wall 5414 of the first rail groove 541 in one end 511 of fork, shown in the little figure of the f as Figure 16, and homographic solution lock status, movable part 54 removes the restriction to friction pulley 41, now, the other end 512 of fork also corresponding sports to the tip position of the second rail groove 542, shown in the little figure of the f as Figure 17.
Above-described embodiment is only used for further illustrating a kind of drawing device with auto-lock function of the present utility model; but the utility model is not limited to embodiment; every above friction module, buckle module etc. are done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all fall in the protection domain of technical solutions of the utility model.
