Description
Technical field
The utility model belongs to field of mechanical technique, relates to the positioning device of connecting rod in a kind of parasols, particularly parasols.
Background technique
The umbrella stand of parasols is made up of fixing rod that is direct rod shape and motion bar, is opening or during folding umbrella support, motion bar can move with respect to fixing rod.That is to say that when umbrella stand folded, motion bar drew in and be close to parallel with fixing rod; When umbrella stand was opened, motion bar favoured fixing rod, and the outer end of motion bar is oblique stretches out and away from fixing rod, was connected the motion bar outer end owing to be used to connect the umbrella frame frame of umbrella cloth, so just made the umbrella frame frame to strut, thereby reached the purpose of sunshade.
The middle part of fixing rod is with a slidably movable sheath, and the top of fixing rod is hinged with a sleeve, and motion bar is through in the sleeve.Be provided with connecting rod between the inner of motion bar and fixing rod, the two ends of connecting rod are hinged on respectively on motion bar and the fixing rod.Umbrella stand just can be located the connecting rod location with motion bar, thereby make the umbrella frame frame on the umbrella stand be in softened state always when being opened.Between connecting rod and movable sheath one, have a positioning means, thereby realize the connecting rod location is about to the motion bar location by this positioning means.
Existing parasols is realized the location by screw and nut, and promptly connecting rod is articulated on the movable sheath one by screw, and in the time of connecting rod need being located, the turn nut makes connecting rod be pressed between screw and the nut, thereby connecting rod is located.
As can be seen,, all want the turn nut at every turn, in operating process, waste time and energy though above-mentioned orientation type can be located connecting rod.Simultaneously, use the screw thread on screw or the nut to lose efficacy for a long time, thereby influence the normal use of parasols.
Summary of the invention
The purpose of this utility model is at existing in prior technology the problems referred to above, and a kind of positioning device that makes that parasols uses connecting rod in the parasols stable and easy and simple to handle is provided.
The purpose of this utility model can realize by following technical proposal: the positioning device of connecting rod in a kind of parasols, be with slidably movable sheath on the fixing rod of parasols, one end of connecting rod is used for motion bar hinged, the other end and the movable sheath of connecting rod are hinged, this positioning device is located between movable sheath and the connecting rod, it is characterized in that, this positioning device is the movable sheath outside several positioning holes that from top to bottom are provided with and the locating piece that can be connected on the connecting rod, when the locating piece of connecting rod on its hinged place swing connecting bar can be corresponding with any one above-mentioned position of positioning hole, and locating piece can be embedded in the positioning hole place.
The umbrella stand of parasols is made up of fixing rod and motion bar, and the top of fixing rod is hinged with a sleeve, and motion bar is through at the sleeve place.The two ends of connecting rod are hinged on respectively on motion bar and the movable sheath.
In the time of need opening parasols, just need make that motion bar is outward-dipping stretches out.That is to say that promote motion bar, movable sheath is along with sliding along fixing rod.After treating that motion bar tilts to stretch out, locating piece is connected on the connecting rod, locating piece is embedded in the positioning hole simultaneously.Obviously, locating piece is connected connecting rod and movable sheath simultaneously, and locating piece has just limited the swing of connecting rod like this, also just the motion bar location has been lived.
On the contrary, locating piece is extracted, connecting rod can be swung, and just can make the motion bar withdrawal, and what motion bar was concordant with fixing rod is close together.
In the positioning device of connecting rod, described locating piece is a latch in above-mentioned parasols, has its aperture jack bigger than latch on the described connecting rod.Latch inserts in jack and the positioning hole, just the connecting rod location can be lived, and prevents connecting rod swing.
In the positioning device of connecting rod, described connecting rod is tabular and its quantity is two, the both sides that are articulated in movable sheath of these two connecting rod symmetries in above-mentioned parasols.Can increase connectivity robustness by such structure, can increase the intensity of connecting rod simultaneously, make connecting rod not fragile.Certainly, the also symmetrical both sides that are articulated in motion bar of the other end of two connecting rods.
In the positioning device of connecting rod, described positioning hole is the through hole that runs through movable sheath in above-mentioned parasols.Such structure makes positioning hole be convenient to processing, and once boring is promptly plastic.
Compared with prior art, the positioning device of connecting rod only needs the plug locating piece to get final product when operation in this parasols.Easy in operating process, quick, therefore, use more convenient.
Simultaneously, for being threaded, the latch connectivity robustness is higher, makes that the stability in use of whole parasols is higher.

Embodiment
As shown in Figure 1, the umbrella stand of parasols is made up of fixing rod 1, motion bar 2, connecting rod 3, movable sheath 4 and sleeve 5 etc.
The bottom of fixing rod 1 has fixed base 1a.Movable sheath 4 is enclosed within on the fixing rod 1, and movable sheath 4 can be free to slide along fixing rod 1.Sleeve 5 is hinged on the top of fixing rod 1, and the middle part of motion bar 2 is through in the sleeve 5.One end of connecting rod 3 is articulated on the movable sheath 4, and the inner of the other end of connecting rod 3 and motion bar 2 is hinged, and the outer end of motion bar 2 is used to connect umbrella frame frame 6.In the present embodiment, the quantity that connecting rod 3 is tabular and connecting rod 3 is two, the both sides that are articulated in movable sheath 4 and motion bar 2 of the two ends symmetry of two connecting rods 3.
As shown in Figures 2 and 3, the positioning device of connecting rod just is arranged between connecting rod 3 and the movable sheath 4 in this parasols, and this device comprises positioning hole 4a, latch 7 and jack 3a.The quantity of positioning hole 4a is three, and these three positioning hole 4a from top to bottom are arranged on the movable sheath 4, and three positioning hole 4a all run through movable sheath 4.Jack 3a is positioned on the connecting rod 3, and the aperture of jack 3a is big than the external diameter of latch 7, and jack 3a also runs through connecting rod 3, and when connecting rod 3 can be corresponding around its hinged place swing jack 3a with the position of any one positioning hole 4a among above-mentioned three positioning hole 4a.Latch 7 can insert in the jack 3a of connecting rod 3, that is to say connecting rod 3 swing after, latch 7 inserts in jack 3a and the positioning hole 4a simultaneously, so just the swing with connecting rod 3 has limited, connecting rod 3 can't be swung, motion bar 2 has also just obtained the location.That is to say that after latch 7 inserted connecting rod 3 jack 3a and positioning hole 4a, the umbrella stand of whole parasols just was in deployed condition always.
Certainly, need latch 7 be extracted by positioning hole 4a place get final product with umbrella stand is folding when drawing in.The swing of connecting rod 3 is unrestricted, and pulling motion bar 2 can make motion bar 2 withdrawals.
