Abstract
The invention provides a large umbrella based on the lever principle, relates to the technical field of umbrellas for shading sunlight and rain, and particularly relates to the technical field of large beach umbrellas, wherein the large umbrella is used for solving the problem that the traditional large umbrella consumes more force in unfolding and folding processes, and is not convenient in use. The large umbrella comprises an umbrella middle bar, an inner middle bar, an upper hub, a middle hub, a lower hub, a long frame, a support frame and a link rod. The large umbrella is characterized in that the lower hub is fixedly connected with the umbrella middle bar; the middle hub is movably jointed with the umbrella middle bar; a connecting seat is movably jointed on a position, below the lower hub, on the umbrella middle bar; a lower pull rod is connected between the connecting seat and the middle hub; and a locking part in match locking with the umbrella middle bar is arranged on the connecting seat. By utilizing the large umbrella, the acting force in an umbrella unfolding process is lightened, and the mode of pulling down the umbrella is more labor-saving and more convenient than the traditional mode of pushing upward the umbrella; the acting forces required by umbrella unfolding and folding processes are basically equal, so the umbrella is unfolded and folded at a uniform velocity in the unfolding or folding process, and the influence to people or objects around is avoided.
Description
Technical field
The present invention relates to the umbrella technical field for sunshade and screening rain, relate in particular to large-scale beach umbrella technical field.
Background technology
At present, the umbrella that is used on the market sunshade and screening rain mainly divides two types, a kind of being of portable form, and another kind is fixed.Portable umbrella considers and carries conveniently, and general volume is little, and structure is light and handy; And fixed umbrella, as: beach umbrella, the large umbrellas such as advertisement umbrella, volume is larger, relatively heavy, generally be to be fixed on the open air, be used for sunshade or take shelter from rain, for the ease of depositing, or be exposed to the sun by the sun when not using and wear out, perhaps being damaged by strong wind for fear of night, also is that fixed umbrella is strutted and draw in operation, because volume is large, heavy again, in operating process, need to exert great efforts and just can finish, in addition, owing to strutting or receiving in the process of disturbing, lower nest mobile range is larger, for a use that stature is not tall and big, in strutting process, also need to lower nest upwards could be pushed into corresponding height by a stool, thereby with the umbrella shaft locking, use quite inconvenience.
Summary of the invention
In sum, the object of the invention is to solve traditional large umbrella strut and the gathering process in the strength that consumes large, and awkward technical problem and the large umbrella of a kind of lever principle of proposing.
For solving technical problem proposed by the invention, the technical scheme of employing is: a kind of large umbrella of lever principle includes: umbrella shaft, interior middle rod, upper nest, middle nest, lower nest, long bone, support rib and gangbar; Described interior middle rod is inserted in the top inner chamber of umbrella shaft, upper nest is fixedly connected with the top of interior middle rod, and described middle nest and lower nest are socketed on the umbrella shaft, and lower nest places the nest below, the tail end of described long bone is connected with upper nest, and the two ends of described support rib are connected with long bone with middle nest respectively; A described gangbar wherein end is connected with lower nest, and the other end is connected on the upper nest tie point and the position between the support rib tie point on the long bone; It is characterized in that: described lower nest is fixedly connected with umbrella shaft, middle nest and umbrella shaft pivot bush unit; Position below described umbrella shaft is positioned at lower nest is gone back movable sleeve and is connected to a Connection Block, also is connected with lower link between Connection Block and middle nest, is provided with the Lock Part that cooperates locking with umbrella shaft at Connection Block.
Described Lock Part be one piece with the perpendicular fastening bolt of umbrella shaft.
Described umbrella shaft is provided with one when umbrella during in full open position, the parachute-opening draw-in groove that matches with fastening bolt.
Described umbrella shaft is provided with one when umbrella during at complete rounding state, the draw-in groove that closes one's umbrella that matches with fastening bolt.
Described umbrella shaft is provided with the bar-shaped trough that embeds for lower link.
The cross section of described bar-shaped trough is semicircle, is provided with protruding limited block at the opening of cross section.
The head of described fastening bolt is handle.
Described Lock Part is snap-fastener, is provided with the parachute-opening flexible clamp piece that matches with snap-fastener in described umbrella shaft.
On described umbrella shaft, also be provided with a flexible clamp piece that closes one's umbrella that matches with snap-fastener.
The bottom of described interior middle rod is provided with the automatic closing umbrella spring.
Beneficial effect of the present invention is: lower nest of the present invention is to be fixed on the umbrella shaft, and the gangbar that is connected with lower nest is as a balance pivot, and long bone is used as lever, has alleviated the active force in the opening process, realizes the labour-saving technique effect; In addition, middle nest is connected by the Connection Block of lower link and lower nest below, realize the parachute-opening operation by drop-down Connection Block, changed the parachute-opening operator scheme of traditional umbrella, because the height of large umbrella is higher than generally than normal adult human height, so the more laborsaving convenience of mode parachute-opening operation that adopts the pull-down pattern parachute-opening upwards to pass than tradition; Also have, because the present invention has utilized lever principle, reaches the effect of stress balance, so that required active force is impartial substantially in whole parachute-opening or the operating process that closes one's umbrella, so be to strut or draw in average rate in parachute-opening or umbrella-folding process, people or thing around avoiding having influence on.
