Abstract

Add the fire hose that revolves handle a kind of having.The additional handle that revolves is at original downside that revolves handle.Two revolve the rotating shaft position are all had gear.Additional revolve the leading role of the setting sleeve of downside under, two revolve gear engagement or separation, thus realization uses two to revolve the switch fire hose respectively.Additional revolving when fastening the fire hose being in a certain definite position.

Description

Have the additional fire hose that revolves handle

The invention belongs to the daily apparatus of switch tap water.

Same the revolving switch of the general use of the existing manual fire hose, this is antihygienic.Open the fire hose with dirty hand, the handle that revolves of the fire hose is polluted, and fastens the fire hose with the hand of cleaning, and revolves having polluted hand again conversely.Contaminated revolving the hand that also can pollute other water users.This situation not only may communicate illness, in the canteen, occasions such as kitchen, lavatory, lavatory also make the people unhappy.

For preventing this situation, can adopt all methods, but these method expenses are higher without the hand switch fire hose, be not suitable for daily life and use.We certainly install two one on the other and revolve handle on the running shaft of the fire hose, switch is respectively used one.But such fire hose uses inconvenience, on revolve hindering a turn backspin handle.If doing longly, rotation is got up slightly convenient, but brings new problem backspin.Because with the distortion that switch is fastened degree difference and rubber washer, revolve position when fastening is changed, this just makes revolving of lengthening a kind ofly be unfavorable for rotation or be unfavorable for the water position of (as doing washing, wash dish, pouring water, wash one's face etc.) being in.In addition, revolve initial position is often changed, make the people not open the fire hose, also bring inconvenience by custom.

For addressing the above problem, the fire hose of the present invention has additional revolve (1) that one one end has gear (3).Gear (3) with on revolve the gear of (7) (4) match.There is projection (6) at gear (3) back side.Projection (6) is revolved the below is enclosed within this and is pressed the groove (5) of the setting sleeve (2) on the basket to match.Rotation earlier is additional during water revolves (1), and additional revolving gear of (1) (3) and gear (4) engagement revolved in the drive (7) are together rotated, thereby open the fire hose.When closing the fire hose, revolve additional revolving of (7) drive in the rotation (1) is rotated, revolve (1) when forwarding a certain position to when adding, its projection (6) falls in the groove (5), and gear (3) and gear (4) are thrown off mutually.No matter at this moment revolve (7) to which direction are rotated, additional revolving still keeps (1) original position motionless.Therefore, as long as the orientation of groove (5) is determined, it is always changeless that the fire hose is fastened an additional position of (1) of revolving, back.Like this, our just available setting sleeve (2) is selected additional revolving the optimum position of (1), and switch not only is convenient to but also be convenient to make the water operation in this position.The water user rotates additional revolving (1) is opened the fire hose, cleans to use to revolve behind the hand (7) are closed a fire hose, then can avoid revolving polluting own or others.

Have additional embodiment of revolving the fire hose of handle below in conjunction with the accompanying drawing detailed description.This fire hose is shown in Fig. 1.The difference of it and the common fire hose is, revolves the downside of (7) is had gear (4) on it, and gear (4) matches the gear of (1) (3) with additional revolving.There is projection (6) at the back side of gear (3), and the groove (5) on projection (6) and the setting sleeve (2) matches.As Fig. 2 and shown in Figure 5, the downside of setting sleeve (2) has a shrinkage pool (8), and shrinkage pool (8) is enclosed within presses on the basket, and setting sleeve (2) can not freely be rotated.As shown in Figure 3, Figure 4, the upside at setting sleeve (2) has a circular groove (5).Setting sleeve (2) can be selected six orientation to entangle and press indigo plant, thereby groove (5) also can be fixed on six different azimuth.When desiring to open the fire hose, promote additional revolving (1) earlier, additional revolving slided the arcuate surface of the projection of (1) (6) along groove (5), will add gradually to revolve (1) is lifted, and makes gear (3) and gear (4) engagement.Continue to promote additional revolving (1), revolve on then (7) under gear driven along with additional revolving rotated (1), the fire hose is opened.

The program of operating this fire hose during water is: 1. rotation additional revolve (1) about 30 ° to open the fire hose.2. wash the additional handle that revolves.3. handle is cleaned.4. revolving in the rotation opens current (7) enough greatly.If on revolve (7) angle of swing greater than 360 °, then additional revolve along with after forwarding initial position to and falling no longer along with on revolve (7) rotated.If on revolve (7) angle of swing less than 360 °, then gear (3) and gear (4) mesh together, additional revolve (1) still with on revolve (7) rotated.5. use up to revolve in the rotation behind the water (7) are closed the fire hose.This moment no matter backspin (1) whether along with rotation, close the fire hose after additional revolving (1) all is in the determined position of setting sleeve (2).

For guaranteeing this fire hose normal operation, the depth of engagement of gear (3) and gear (4) should be greater than the pitch of fire hose swing arm screw thread, and the degree of depth of groove (5) should be slightly larger than the depth of engagement.Can guarantee like this to revolve and can not throw off (7) gear (3) when doing first week rotation midway with gear (4), revolving in the time of can avoiding fastening the fire hose again simultaneously descended (7) lowly will revolve stuck gear (3) and the improper engagement of gear (4).

Additional revolve (1) and on revolve can cast also and can use macromolecular material mold pressing or injection moulding manufacturing (7).The hole wall of its center hole (9) can add a brass bushing to increase wear resistance and corrosion stability.The profile of tooth of gear (3) and (4) should be convenient to additional revolving (1) cambered surface along groove (5) is risen to finish the engagement between gear (3) and (4) as shown in the figure like this

Obviously, two of the fire hose revolve also can be made into other shape more attractive in appearance.

Claims

1, a kind of water tap, the Qi Te emblem is to have two to revolve handle, and two revolve all having gear at the rotating shaft position, additional revolve below a location condom is arranged on fire hose swing arm, the setting sleeve upside has an arc groove, and this groove matches the projection at the gear back side with additional revolving.
