Description

A kind of umbrella nest buckling device

Technical field

The utility model relates to a kind of umbrella nest buckling devices.

Background technique

Umbrella is articles for daily use indispensable in people's life.Wherein, the umbrella frame structure of en-toutcas and straight rod umbrella is usually in Stick, honeycomb and middle bar construction realize the folding of umbrella by the connection cooperation of honeycomb and medium rod.In general, honeycomb include upper nest and Lower nest.Currently, existing Honeycomb device is divided into following several types: first, push type Honeycomb device, structure is simple, but has Two disadvantages cause to block in parachute-opening and umbrella-folding process first is that the grab of key before being caught in card hole, can be permanently connected to medium rod Hook scrapes medium rod, the surface wear of medium rod can be influenced appearance over time, second is that needing first to draw bee again by key when closing one's umbrella The lower nest of nest could thread off, and the movement to close one's umbrella is more comparatively laborious；Second, plug-type Honeycomb device, structure is complicated, still, works as umbrella Have it is in the open state under, easily occurred threading off and the phenomenon that promptly folding occur by external force, stability is low, also, In When parachute-opening, honeycomb can also rub phase mutual friction with medium rod, to influence medium rod appearance, or even honeycomb occur and lose control of one's feelings the showing of medium rod As.

China Patent No.: 201621066347.7 disclose Umbrella runner device, including are fixedly connected on middle stick of umbrella top The upper nest of end and the lower nest component that is sheathed on middle stick of umbrella outside and can be slided up and down along middle stick of umbrella axial direction, it is described Lower nest component is located at below the upper nest, and the outside of the upper nest is equipped with an at least grab, and the lower nest component includes being sheathed on Helping pull a cart on the outside of middle stick of umbrella and be sheathed on it is described help pull a cart outside and along middle stick of umbrella axial direction can relatively it is described help pull a cart on The guide sleeve of lower slider, it is described help pull a cart offered on the lower section of the guide sleeve, the guide sleeve in it is described help pull a cart it is opposite The guide sleeve downlink can be along the middle stick of umbrella radial direction at least elastic slice that deformation occurs outward, each elastic slice when sliding The card hole being interlocked with the grab is offered, deformation occurs outward along middle stick of umbrella radial direction in the elastic slice for the card hole When be detached from the grab.In umbrella opening procedure, lower nest component is axially facing upper nest along middle stick of umbrella and slides the Honeycomb device Row pushes to help pull a cart that guide sleeve being driven to slide together towards upper nest, when the buckle that the elastic slice on guide sleeve is correspondingly arranged is connected in When grab, lower nest component is connected to nest, at this point, umbrella is in full open position and keeps stable；Umbrella is folding process In, apply active force towards away from guide sleeve direction to helping pull a cart, each elastic slice on guide sleeve is along middle stick of umbrella radial direction to outgoing Raw deformation, i.e. card hole on elastic slice is detached from grab, at this point, umbrella is in collapse state.When the card hole of elastic slice is connected in When buckle, the stress point of card hole is located at hole side-walls, i.e. the stress point of card hole is located on elastic slice, when middle stick of umbrella is by along its axis To direction active force when, the stress point of elastic slice and turning point are on same straight line, i.e., elastic slice is by along middle stick of umbrella axis To direction active force when, there is no rotation the arm of force, in this way, elastic slice is along middle stick of umbrella radial direction, deformation occurs outward, makes It obtains grab to be connected in card hole always, so that it is guaranteed that the stability of Umbrella runner device；But elastic slice is being used for multiple times and stress When excessive, certain deformation can be generated, causes buckle and card hole cooperation on elastic slice not close, causes structural stability poor, bear Dynamics is small.

Utility model content

Therefore, for above-mentioned problem, the utility model provides a kind of umbrella nest buckling device, it mainly solves existing skill Art sector-meeting of being hit by a bullet generates certain deformation, causes buckle and card hole cooperation on elastic slice not close, causes structural stability poor, receiving The small problem of dynamics.

To achieve the above object, the utility model uses following technical scheme:

A kind of umbrella nest buckling device, including upper nest, lower nest and medium rod, the lower end of the upper nest extend downward with two Flexible buckle is axisymmetricly arranged centered on the central axes of the two above nests of the buckle, and the lower nest includes guide sleeve And it is set in the push-and-pull set on the outside of guide sleeve, the upside and buckle relative position of the guide sleeve inner surface are provided with guide groove, The distance between distance buckle described less than two between the bottom surface of two guide grooves, the lower end on the guide sleeve positioned at guide groove is passed through The logical through slot that is provided with is caught in through slot when upper nest and lower nest fasten.

Further, position is provided with push/pull slot, the push/pull slot with through slot on the inner surface of the push-and-pull set Upper end be provided with jacking block, the lower end surface of the jacking block is obliquely installed.

Further, the upper end of the guide sleeve and guide groove are provided with and communicated with inclined surface.

It further, is in 30 °~60 ° oblique angles between the lower end and medium rod of the buckle.

By using preceding solution, the beneficial effects of the utility model are: this umbrella nest buckling device, pushes up push-and-pull Set, so that lower nest is moved upwards along medium rod, the buckle on guide sleeve and upper nest is squeezed, so that buckle flexible deformation, and along guide groove Sliding realizes parachute-opening to snap into through slot, the fastening of upper nest and lower nest；Pull down push-and-pull set so that lower nest along medium rod to Upper movement, buckle and guide sleeve on upper nest squeeze and occur flexible deformation, to be detached from lower nest after guide groove sliding, upper nest with The separation of lower nest, realization close one's umbrella, and two buckles are arranged, so that the dynamics of receiving is small, stress dynamics is uniform, and buckle towards outer end, Reduce the deformation quantity for being buckled in use process, effectively keeps the rate of tension of buckle, improve the stability of structure；Further, it pushes away Help pull a cart upper setting push/pull slot be conducive to improve two buckles strut distance, to increase the fastening stability of upper nest and lower nest, When the jacking block of setting is conducive to the drop-down of lower nest, the disengaging of buckle and through slot is easy to use；Further, it is arranged on guide sleeve It is in 30 °~60 ° oblique angles between inclined surface and the lower end and medium rod of buckle, is conducive to the fastening of buckle with through slot, operation peace Entirely, conveniently.
