Description

Hang the closing device of umbrella

The utility model relates to a kind of parts open-and-close mechanism of umbrella, suits especially to make umbrella strut, draw in the closing device that hangs umbrella of use large-scale hanging on the umbrella with manual methods.

More existing large-scale parasols, hang umbrella and all adopt electronic closing device, but just can't use on the limit, sandy beach of not having electricity.

And adopt manual closing device, and use a rope more, the one end is fixed on the crank handle, and other holds by the pulley of the riser top ends that is connected with umbrella frame respectively and after upward coiling, other is fixed on the lower wall by end.Make and hang opening and closing umbrella, need very long rope to be wrapped on the arbor of shaking the hand, use very inconvenient and crank handle is required great effort very much, rope is also fragile.

The purpose of this utility model is to provide a kind of closing device that hangs umbrella, makes that to hang opening and closing umbrella convenient, light, laborsaving, and durable in use.

The utility model is achieved in that the closing device that hangs umbrella by being fixed on the handle that has rope on the standpipe, and rope is fixed on the lower wall by pulley in umbrella frame and the last dish and umbrella post and forms through the pulley of riser top ends.And rope, one end is fixed on the handle, and end is connected with slide by the pulley of riser top ends in addition, and root rope one end is fixed on the standpipe in addition, in addition end enters umbrella frame by the pulley on the slide and pulley and the umbrella post gone up in the dish are fixed on the lower wall, and slide and standpipe are slidingly matched.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Standpipe (3) is made by the rectangular aluminium alloy section bar, and one side both sides are slideway, is the rope road (22) that passes rope (15) Yi Bian by the centre arc groove is arranged.Top end has a top cover (7), connect pulley (6) with bearing pin on the inside side both sides wall, pass rope (5), use an end of bolt, nut fixed support bar (11) on the outside side both sides wall, support bar (11) is held on the fixed block (12) that is fixed on the umbrella frame (14) in addition, umbrella frame (14) is connected with support bone (18) by pipe clamp (13), lower wall (17) is connected with support bone (18), Handle axis is passed standpipe (3) lower end two outer walls and is fixed on the standpipe (3), at the handle axle head fixed handle (4) of an outer wall, this all with prior art hang that umbrella is the same not to be described in detail.

Slide (9) is an end opening, and rectangular through-hole is arranged in the end wall

Shape is fixed 4 one-way shaft at the upper and lower end of two outer walls that through hole end is arranged, and each is gone up and connects a roller (21), and a suspension hook (8) is fixed in the upper end.Respectively the umbrella frame (14) of pulley (10) and band pulley (10) is fixed on two outer walls of slideway (9) with two bearing pins (20).

Slide (9) utilizes the roller (21) on it to embed in the slideway on standpipe (3) one side both sides, and is slidingly matched with it.

One end of rope (5) is fixed on handle (4) axle, and in addition end is walked around on the suspension hook (8) that pulley (6) is fixed on slide (9).

One end of rope (15) is fixed on standpipe (3) wall under the handle (4), and upwards along the rope road (22) of standpipe (3) one sides to slide (9), behind the pulley (10) on the pile warp slide (9), walk around the pulley (10) of umbrella frame (14) end again, enter umbrella frame (14) cavity, pulley (10) on pile warp in the dish (16), enter lower wall (17), be fixed at last in the ball on lower wall (17) bottom surface, hang umbrella and closing device is assembled into, be fixed in the sleeve pipe (2), and be fixed on base plate (1) and go up and just can use.

During use, with crank handle (4), make rope (5) constantly involve in Handle axis, the suspension hook (8) that is connected with rope (5), just drive moves up along slideway and rope road (22) by roller (21) with the slide (9) of its one, and support bar (11) is outwards strutted, simultaneously through connected fixed block (12), umbrella frame (14) is upwards lifted, pulley (10) in last dish (16) again, promote lower wall (17), after support bone (18) by pipe clamp (13), struts umbrella frame (14) fully.Handle (4) makes its locking by locking device.

When closing one's umbrella, as long as oppositely shake handle (4), unclamp rope (5), slide (9) is at gravity effect lower edge slideway, and rope road (22) move down, and umbrella is also drawn in, and it is nearest from lanyard point position, at this moment rope (5) is all decontroled, and rope (15) is also left behind lower wall (17), throws off the umbrella post (19) that links to each other with last dish (16).

Also can be on ' make an end opening, an end is an annular, a suspension hook (8) is fixed in the upper end, directly is enclosed within circular standpipe (3) behind liner one plastic sheath (23) ' with slide (9), structure as shown in Figure 5.

The utility model is compared with prior art: because an original rope being divided into two fully independently ropes Rope, the directly upper and lower action of control slide, the opening and closing action by slide control umbrella. Make The total length of rope reduces, and the rope that especially is wrapped on the Handle axis greatly reduces, and can not fill up whole umbrella Tube space, use like this with regard to light, laborsaving, can not be very difficult, the people that strength is little can operate. Also Can not spoil, damage rope, make it durable in use.
