Description

Automatically umbrella opens rogger-roll device

Technical field

The utility model relates to the parts of the parachute kit in the daily necessities, particularly to the improvement of opening the rogger-roll device structure of straight rib self-opening umbrella.

Background technology

The parachute opener of existing automatic umbrella has and is applied to many folding umbrellas, also have and to be applied to vertical frame umbrella, cause the problems such as intensity reduction of middle rod for easy to use with preventing to slot on the rod in umbrella, the button that most automatic umbrella all will be controlled parachute-opening is arranged on the handle of umbrella.For many foldings umbrella, it does slightlyer for handle of umbrella that the umbrella holder grips usually, and is therefore can be with parachute-opening button and associated components built-in and make whole being made of one of handle of umbrella, makes its profile more attractive in appearance; And for straight rib self-opening umbrella, its handle of umbrella adopts the form of elbow usually, its diameter is thinner, to just have any problem the parachute-opening button is built-in, therefore the parachute-opening button exposes to outside the handle of umbrella usually, it as application number 90226132 Chinese utility model patent, its disclosed automatic umbrella opener device as shown in Figure 8, be to extend the collar stop 83 that a band back-moving spring 82 is set in the pipeline section downwards at Umbrella runner 81, at umbrella closing state, this collar stop 83 is extrapolated to the extension pipeline section of the outstanding nest 81 down of part by spring 82 and puts in the groove of handle of umbrella 84 inwalls and will descend nest 81 fixing; During parachute-opening, push button 85 nest 81 under the interior release of the extension pipeline section that is pushed into down nest 81 in this collar stop 83 can be realized parachute-opening.Because the extension pipeline section of this time nest 81 is wanted built-in collar stop 83 and spring 82, therefore its external diameter is bigger, correspondingly, the part external diameter that button 85 is set on the handle of umbrella 84 need do more, cause handle of umbrella 84 to be divided into small one and large one two parts thus, and its button 85 evaginations, the monnolithic case of handle of umbrella is not too attractive in appearance.

The utility model content

The technical problem that will solve of the present utility model provide a kind of parachute-opening button do not protrude the handle of umbrella surface straight rib self-opening umbrella open rogger-roll device.

The purpose of this utility model can realize by adopting following technical scheme: design a kind of rogger-roll device of opening of automatic umbrella, comprise that the handle of umbrella that is connected with middle rod end, parachute-opening button, the slip cap that is installed in the handle of umbrella surface are connected on the following nest of middle rod and the latch components of opening, closing one's umbrella; The base portion of described parachute-opening button is the part torus of inserting described handle of umbrella cavity, the outer surface of its outer surface and described handle of umbrella is along being connected into the face of cylinder, described latch components comprises clamping part, the recess that is arranged on the described extension of nest bottom down pipeline section and the back-moving spring that acts on described clamping part that extends internally from described parachute-opening button base part, described clamping part is kept away a groove a bit of distance of sliding by the handle of umbrella inwall, under umbrella closing state, described back-moving spring is pushed into the described nest down of locking in the described recess with described clamping part.

Described clamping part can adopt following two kinds of structures:

One, described clamping part is the projection that is fixed on parachute-opening button posterior medial, and the top of this projection is yearned for interior toward the inclined-plane that has a down dip for the footpath.

Two, described clamping part is the rear portion ring section of parachute-opening button itself, and this rear portion is encircled section top and yearned for interior toward the inclined-plane that has a down dip for the footpath.

In order to take in smoothly in the cavity of handle of umbrella top, the lower edge that pipeline section is extended in described nest bottom down has chamfering.

A groove of keeping away of described handle of umbrella inwall each side is arranged with a stopper slot, and the ring section at described parachute-opening button base part rear portion each side is provided with a spacing projection that stretches in each side stopper slot.When the front end wall of this spacing projection and stopper slot offseted, the outer surface of parachute-opening button was just in time concordant with the handle of umbrella outer surface along connecing.

The outside at described parachute-opening button rear portion offers a shrinkage pool, and described keeping away on the groove position relative with this shrinkage pool offers a locating hole, and described back-moving spring is folded between above-mentioned shrinkage pool and the locating hole, and this structure helps the location of back-moving spring.

Compared with prior art, the rogger-roll device of opening of automatic umbrella of the present utility model has adopted rear portion annulus section can place the handle of umbrella inwall to keep away the interior parachute-opening button of a groove, the clamping part that utilization is arranged on parachute-opening button rear portion and following nest bottom extend on the pipeline section recess mutually clamping fix nest down, reduced the volume of time nest bottom extension pipeline section greatly, but make the handle of umbrella integrated setting thus, and the pressing key of parachute-opening button and handle of umbrella surface are along being connected into the face of cylinder, and the profile of whole handle of umbrella is very attractive in appearance.
