Description

Hang the umbrella retaining mechanism

Technical field

The utility model relates to the bend pipe adjusting device of hanging umbrella, is a kind of umbrella retaining mechanism that hangs.

Background technology

Parasol (or claiming parasols) is a kind of umbrella that hides anti-direct irradiation of sunlight that is mainly used in, the some of them parasol is not to strut umbrella frame and umbrella cover by the umbrella bar that is positioned at the umbrella frame center, but hang umbrella frame and umbrella cover, and strut umbrella frame and umbrella cover by upwards promoting umbrella frame by the umbrella bar of umbrella frame and umbrella cover one side.The parasol of above-mentioned this mode is called and hangs umbrella or banana hangs umbrella, and its umbrella bar is made up of bend pipe and vertical rod, is connected by hanging the umbrella retaining mechanism between bend pipe and the vertical rod.Its umbrella bar generally is made up of bend pipe, pull bar, vertical rod, umbrella retaining mechanism, and generally the handrail shell of the sliding sleeve by pull bar and vertical rod is with the fixed angle of vertical rod and pull bar for retaining mechanism, and the angle of inclination of umbrella cover can be controlled in the position that moves up and down the handrail shell.

As the patent No. ZL200720106096.5 of Chinese patent literature publication, Granted publication CN201001460Y, Granted publication day is on January 9th, 2008, utility model title " a kind of simple and easy banana hangs umbrella "; The patent No. ZL200820165212.5 of Chinese patent literature publication and for example, Granted publication CN201256675Y, Granted publication day is on June 17th, 2009, utility model title " plug-type curved boom hangs umbrella "; The patent No. ZL200720086869.8 of Chinese patent literature publication for another example, Granted publication CN201073045Y, Granted publication day is on June 18th, 2008, utility model title " positioner of banana sunshade umbrella ".But above-mentioned retaining mechanism shortcoming of hanging umbrella is to use operation comparatively convenient, heavy; And defective such as wearing and tearing tubing surface plastic spraying appears easily in the sliding process of bend pipe and vertical rod, greatly reduced the quality of product.

Summary of the invention

For solving above-mentioned deficiency, the utility model provides a kind of umbrella retaining mechanism that hangs to this area, makes it solve in the existing like product that structural design is not good enough to cause being used in the degree of tightness of bend pipe when hanging umbrella and the technical problem of angular adjustment inconvenience.Its objective is and be achieved through the following technical solutions.

A kind of umbrella retaining mechanism that hangs, this mechanism comprises sliding seat, knob, pulley assembly, pulley assembly comprises screw cap, V-type pulley, screw, is with the vertical rod and the bend pipe that hang umbrella in the sliding seat; By the position of this mechanism's adjusting bend pipe, regulate the height and the angle of inclination of umbrella cover, umbrella frame then; Vertical rod is connected with umbrella shank, by the fixedly vertical rod of this umbrella shank, sliding seat, bend pipe, umbrella frame, umbrella cover.The sliding seat that its design main points are described sliding seat and bend pipe junction is provided with through hole, is provided with the on-slip part in the through hole of sliding seat, and an end and the bend pipe of on-slip part offset, and the other end is connected with knob, and knob is threaded with the sliding seat external diameter.Sliding seat utilizes hand to twist the principle of knob screw thread propelling stroke, props up bend pipe by the on-slip part that connects knob, realizes the locking to the bend pipe optional position; Promptly counterclockwise or the clockwise direction turning knob, the on-slip part is compressed or unclamp bend pipe.Be provided with pulley assembly in the described sliding seat, be connected with pulley assembly when bend pipe is inserted in sliding seat, the V-type pulley of pulley assembly is fixed in by screw in the through hole of sliding seat, and screw is provided with the screw cap at the correspondence position of sliding seat.Displacement by pulley assembly guiding bend pipe has reduced the active force when bend pipe moves, so that bend pipe slides easily; Reduce the force of sliding friction of bend pipe simultaneously, reduce the damage of sliding seat tube surfaces plastic-blasting on the bend pipe.

Be provided with position block between described sliding seat and the knob, knob, position block, on-slip part are connected as a single entity by self-tapping screw, and the self-tapping screw hole is provided with the knob cap.Be that position block is fixed in the screw thread square groove of sliding seat, the on-slip part passes with knob and is connected tightening by self-tapping screw from being fixed on position block inboard on the sliding seat.Position block makes active force indirectly-acting between sliding seat and the knob in position block, has improved the stability by knob degree of tightness bend pipe.Drive the effect that on-slip part extruding bend pipe can play fixed bending tube by turning knob during use, the effect of position block is the outer wall that blocks the on-slip part when unclamping knob, thereby knob can not be come off from the screw thread of sliding seat.

Described vertical rod is connected with sliding seat, and the vertical rod of junction, sliding seat are provided with corresponding through hole, are provided with spring housing in the through hole of vertical rod, and the both ends of the spring in the spring housing is respectively equipped with hoodle.The hoodle that elastic force effect by spring promotes two ends moves horizontally in the through hole of sliding seat, even the time spent, make vertical rod install from sliding seat and separate by the mode of pushing hoodle, this mode has made things convenient for the loading and unloading between vertical rod and the sliding seat, has reduced the packaging volume of product.

The cross section of described vertical rod and bend pipe is regular hexagon.The vertical rod of this structure and bend pipe crushing resistance are good, are difficult for taking place deformation and bending, are difficult for rotating simultaneously under stressed situation.The cross section bore of bend pipe is increased to top umbrella cover end by the bottom.This structure prevents to cause the landing in the sliding seat fast of bend pipe gravitate because knob unclamps excessively, injures operating personnel, and the bend pipe damage that makes impact with the ground.

Be provided with three groups of pulley assemblies in the described sliding seat, three groups of triangular in shape arranging of pulley assembly, two groups of pulley assemblies are positioned at the bottom of sliding seat, and another group pulley assembly is positioned at the top of sliding seat.This design is the best design of pulley assembly, makes the displacement of bend pipe in sliding seat further stable.According to the design feature of above-mentioned pulley assembly and the design of this pulley assembly,

At least be provided with one group of pulley assembly in the described sliding seat, pulley assembly adopts one group, more than two groups or three groups, and corresponding other combination arrangement mode, reaches the purpose of guiding bend pipe displacement.

The utility model is installed on vertical rod, only needs the degree of tightness knob can regulate the bend pipe height and the angle of hanging umbrella, and it is reasonable in design, and good looking appearance is simple in structure, practical, and operation, use, easy to loading and unloading are applicable to all kinds of umbrellas that hang, and the improvement of hanging the umbrella retaining mechanism.
