Abstract
The utility model relates to a fast umbrella opening mechanism of reducing the time of the down nest rising. The utility model is mainly made of a top and bottom nests, pulleys A, B, parachute cords A, B and a control mechanism. The top nest is fixed on the upper extreme of the stick. The pulley A is arranged in the top nest, the bottom nest is looped on the stick. The pulley B can move up and down by erecting the pulley in the stick. One end of the parachute cord A connects with the bottom nest, another end connects with the top nest by going around the pulley A and pulley B. Both sides of the parachute cord B connect separately with the pulley and the rope axis on the control mechanism. An I-shaped gum cover wraps on the rope axis. The umbrella opening mechanism has the merits of quick opening speed and long parachute cord service life.
Description
Technical field
The utility model relates to a kind of parachute deployment means of parasols, especially a kind of parachute deployment means that can fast umbrella be opened.
Background technology
The parasols parachute deployment means of prior art includes upper and lower nest, pulley, umbrella rope and operating mechanism usually, its middle pulley is fixed in the nest, one end of umbrella rope is connected with following nest, the other end is connected with operating mechanism after walking around pulley, by operating mechanism coiling umbrella rope, reach the purpose of parachute-opening by nest rising under the pulling of umbrella rope.In this structure down the rate of climb of nest and umbrella rope be consistent by winding speed.Therefore from the parachute deployment means of prior art,, have only by fast winding umbrella rope and could realize if will will descend nest to mention fast.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of quick parachute deployment means of going up the nest rise time of shortening will be provided, and can make the parachute-opening rapid operation by this mechanism, can at short notice umbrella be opened rapidly.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this quick parachute deployment means, include, following nest, pulley A, umbrella rope A and operating mechanism, wherein go up nest and be fixed in middle rod upper end, pulley A is located in the nest, following nest is set on the middle rod, it is characterized in that it also includes a umbrella rope B and at umbrella rope effect pulley B movable up and down, pulley B is located in the middle rod by pulley yoke, the end of described umbrella rope A is fixed with following nest, other end pile warp pulley A and pulley B and last nest are fixed, the end of described umbrella rope B is connected with pulley yoke, and the other end is connected with the reel for rope of operating mechanism.
Described pulley yoke can be made a cylindrical member, the pulley groove and the rope hole that are used for that pulley is installed and wear the umbrella rope are arranged on it, cause the umbrella rope to be screwed in together in order to prevent pulley yoke from middle rod, rotating in addition, between the outer wall of pulley yoke and middle excellent inwall, be respectively equipped with suitable groove and raised line.
For the friction that prevents umbrella rope and middle excellent inwall and reduce the umbrella rope around the number of turns, on described reel for rope, can overlap an I-shaped garment bag.
Compared with prior art, advantage of the present utility model is: because by setting up a pulley and umbrella rope, make entire mechanism form a movable pulley structure, the twice that the speed that makes down the nest rising is the umbrella rope on the reel for rope forever, thereby can shorten the following nest rise time, reach the purpose of quick parachute-opening; In addition, on reel for rope, be with garment bag, not only can avoid the umbrella rope to contact and the friction that produces, increased the service life of umbrella rope, and can increase the diameter of reel for rope with tube wall, make the umbrella rope around the number of turns reduce, thereby nest is risen faster.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the assembling schematic diagram between reflection pulley yoke and middle excellent inwall.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
With reference to shown in Figure 1, quick parachute opener of the present utility model mainly is to be made of last nest 1, following nest 5, pulley A2, pulley B3, umbrella rope A11, umbrella rope B10, pulley yoke 4, garment bag 7 and operating mechanism 9 etc., wherein go up nest 1 be fixed in excellent 6 upper ends, which is provided with pulley groove, pulley A2 is contained in the pulley groove.
Pulley yoke 4 be contained in nest 1 below middle excellent 6 in, its profile is made cylindrical, in be shaped on pulley groove and the rope hole, pulley B3 is contained in the pulley groove of pulley yoke 4.Symmetrical both sides at pulley yoke 4 outer walls are shaped on axial notch 12, accordingly on middle excellent 6 inwalls, be shaped on the raised line 13 that matches with groove 12, the spacing pulley yoke 4 that can make by groove 12 and raised line 13 can not cause rotation in process of rising or falling, thereby the umbrella rope is screwed in together.
Following nest 5 is enclosed within on middle excellent 6 between operating mechanism 9 and the last nest 1, has special umbrella rope hole on it, is used for fixing umbrella rope A11.
The end of umbrella rope A11 is connected down the place, umbrella rope hole of nest 5, and the other end is fixed on the nest 1 after walking around pulley A2 and pulley B3.The end of umbrella rope B10 is connected the place, rope hole of pulley yoke 4, and the other end is connected on the reel for rope 8.By pulley A, B2,3 and umbrella rope A, B11,10 constitute a movable pulley device, the twice that the speed that nest 5 is risen is the umbrella rope on the reel for rope forever, thus can shorten following 5 rise time of nest, reach the purpose of quick parachute-opening.
When operating mechanism 9 comes into operation, umbrella rope B10 is just continuous, and umbrella rope B10 just pulls down pulley yoke 4 on the garment bag 7 of operating mechanism, and nest 5 is just upwards drawn at present together, this is the speed that rises of nest 5 twice that is umbrella rope 10 on the reel for rope 8 at present, therefore umbrella can be opened fast.
