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 that is used for sunshade and hides rain, relate in particular to large-scale beach umbrella technical field.
Background technology
At present, the umbrella that is used for sunshade and screening rain on the market mainly divides two types, a kind of being of portable form, and another kind is fixed.Portable umbrella considers and carries conveniently that general volume is little, and structure is light and handy; And fixed umbrella, as: beach umbrella, large umbrellas such as advertisement umbrella, volume is bigger, 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 big, 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, following nest mobile range is bigger, for a use that stature is not tall and big, in the process of strutting, also need could will descend nest upwards to be pushed into corresponding height by a stool, thereby, use quite inconvenience with rod locking in the umbrella.

For solving technical problem proposed by the invention, the technical scheme of employing is: a kind of large umbrella of lever principle includes: rod in the umbrella, interior in rod, go up nest, middle nest, nest, long bone, support bone and gangbar down; Rod is inserted in the top inner chamber of rod in the umbrella in described, last nest with interior in the top of rod fixedly connected, described in nest and following nest be socketed in the umbrella on the rod, following nest places below the nest, the tail end of described long bone is connected with last nest, and the two ends of described support bone are connected with long bone with middle nest respectively; A described gangbar wherein end is connected with following nest, and the other end is connected on the last nest tie point and the position between the support bone tie point on the long bone; It is characterized in that: excellently in described down nest and the umbrella fixedly connected excellent pivot bush unit in middle nest and the umbrella; Go back movable sleeve on the position under rod is positioned in described umbrella below the nest and be connected to a Connection Block, between Connection Block and middle nest, also be connected with lower link, on Connection Block, be provided with the Lock Part that cooperates locking with rod in the umbrella.
Described Lock Part be one piece with umbrella in the perpendicular fastening bolt of rod.
Rod is provided with one when umbrella during in full open position, the parachute-opening draw-in groove that matches with fastening bolt in the described umbrella.
Rod 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 in the described umbrella.
Rod is provided with the bar-shaped trough that embeds for lower link in the described umbrella.
The cross section of described bar-shaped trough is semicircle, is provided with protruding limited block on the opening of cross section.
The head of described fastening bolt is a handle.
Described Lock Part is a snap-fastener, is provided with the parachute-opening flexible clamp piece that matches with snap-fastener in described umbrella on the rod.
In described umbrella, also be provided with a flexible clamp piece that closes one's umbrella that matches with snap-fastener on the rod.
The bottom of rod is provided with automatic umbrella colsing spring in described.
Beneficial effect of the present invention is: down nest of the present invention is to be fixed in the umbrella on the rod, and the gangbar that is connected with following nest is as a balance pivot, and long bone is used as lever, has alleviated the active force in the parachute-opening process, realization labour-saving technique effect; In addition, middle nest is connected by the Connection Block of lower link with following nest below, realize the parachute-opening operation by drop-down Connection Block, changed the parachute-opening operator scheme of traditional umbrella, because of 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, makes that required active force is impartial substantially in the whole parachute-opening or the operating process that closes one's umbrella, so in the parachute-opening or the process that closes one's umbrella, be to strut or draw in average rate, people or thing around avoiding having influence on.
