Preferably, described involucrum is spliced by the first involucrum longitudinally split is relative with the second involucrum.Certainly, involucrum also can adopt integrative-structure.
Preferably, the rear being positioned at described longitudinal hole in the both sides of described involucrum has cross through hole, the rear lateral portion of described handle is located at involucrum inside and is positioned at the rear of this cross through hole, the front side portion of handle exposes to involucrum and is positioned at described cross through hole, bottom and the involucrum inside of handle are hinged, the top of handle and the rear end of a slide block are hinged, described slide block is positioned at involucrum and is located at the top of cross through hole, described friction spacer is arranged on the front end of described slide block, the slideway being provided with above cross through hole and slidably reciprocating for described slide block is positioned in described involucrum, the elastic component making the handle after pulling maintain the trend of unclamping is provided with in the inside of described involucrum.
Further preferably, a locating hole is had in the upper end of described handle rear lateral portion, the front end of one alignment pin is stretched in this locating hole, and it is outer and offset with rear wall in described involucrum that the rear end of described alignment pin stretches out in this locating hole, and described elastic component is be arranged on the spring on described alignment pin.Like this, pull handle and can make spring-compressed, hand is from after handle unclamps, and the spring of compression is reset and under the elastic force effect of spring, handle is unclamped.
In order to make sliding up and down of whole handle positioning device relative umbrella bar more steady, be respectively provided with about two rollers spaced apart in the both sides of described longitudinal hole.
Further preferably, the first described involucrum with the second involucrum have four installing holes corresponding with described roller, and be fixed with bearing pin between the first involucrum and the corresponding installing hole on the second involucrum, described roller housing is located on the bearing pin of described correspondence.
Further preferably, be provided with at the front side portion of described involucrum installing hole of shaking the hand, at the front side portion of involucrum and the front upper place of installing hole of shaking the hand described in being positioned at is provided with the installation portion that the brace for parasols is installed.
Compared with prior art, the utility model has the advantage of: need not punch on umbrella bar and tooth bar is installed when this handle positioning device is installed, mounting structure is very simple, and location is also comparatively firm, and because handle positioning device is contacted on umbrella bar by roller-coaster, thus, after friction spacer departs from umbrella bar, handle positioning device can move up and down more smoothly along umbrella bar.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figures 1 to 5, the handle positioning device for parasols in the present embodiment includes the first involucrum 1 and the second involucrum 2 longitudinally separated, first involucrum 1 is spliced to form involucrum mutually with the second involucrum 2, the longitudinal hole 3 passed for umbrella bar 17 is formed in the middle part of involucrum, the both sides being positioned at longitudinal hole 3 in involucrum inside are respectively provided with about two rollers 4 spaced apart, when handle positioning device is installed on umbrella bar 17, roller 4 and umbrella bar 17 keep Structure deformation, the effect of roller be on the one hand by spacing for handle positioning device on umbrella bar 17, on the other hand that handle positioning device is slided up and down along umbrella bar 17 is more smooth and easy.First involucrum 1 and the second involucrum 2 have four installing holes 13, first involucrum 1 corresponding with roller 4 and is fixed with bearing pin 14 with between the corresponding installing hole 13 on the second involucrum 2, roller 4 is set on corresponding bearing pin 14.
The rear being positioned at longitudinal hole 3 in the both sides of involucrum has cross through hole 7, handle 6 is arranged on involucrum, the rear lateral portion of handle 6 is located at involucrum inside and is positioned at the rear of this cross through hole 7, the front side portion of handle 6 exposes to involucrum and is positioned at cross through hole 7, bottom and the involucrum inside of handle 6 are hinged, be positioned in involucrum above cross through hole 7 and be provided with slide block 8, the rear end of slide block 8 and the top of handle 6 are hinged, friction spacer 5 is installed in the front end of slide block 8, the slideway 9 being provided with above cross through hole and slidably reciprocating for slide block 8 is positioned in involucrum, the elastic component making the handle after pulling 6 maintain the trend of unclamping is provided with in the inside of involucrum.In the present embodiment, locating hole 10 is had in the upper end of handle 6 rear lateral portion, alignment pin 11 is installed in locating hole 10, the front end of alignment pin 11 is stretched in this locating hole 10, it is outer and offset with rear wall in involucrum that the rear end of alignment pin 11 stretches out in locating hole 10, further, described elastic component is the spring 12 be arranged on alignment pin 11.
In addition, be provided with at the front side portion of involucrum installing hole 15 of shaking the hand, at the front side portion of involucrum and the front upper place being positioned at installing hole 15 of shaking the hand is provided with the installation portion 16 that the brace 18 for parasols is installed.The mounting structure of (not shown) and brace 18 of shaking the hand is conventional structure, does not repeat them here.
Operation principle: pull handle 6, spring 12 is compressed, handle 6 is with movable slider 8 to shrink back, slide block 8 is with dynamic friction spacer 5 move backward and depart from umbrella bar 17, thus realize whole handle positioning device and can move up and down along umbrella bar 17, and in moving process, the roller 4 in involucrum keeps slidingly contacting with umbrella bar 17 all the time.Unclamp handle 6, resetted by the spring 12 compressed, under the elastic force effect of spring 12, slide block 8 moves forward voluntarily, and slide block 8 is with dynamic friction spacer 5 move forward and pin umbrella bar 17, thus makes handle positioning device be positioned on umbrella bar 17, to realize positioning action.
The foregoing is only preferred embodiment of the present utility model; should be understood that; for those of ordinary skills; do not departing under principle prerequisite of the present utility model; multiple remodeling or improvement can be carried out to the utility model; the main body of such as involucrum can also adopt integrative-structure, and these are all regarded as within protection domain of the present utility model.
