Abstract

The utility model discloses an umbrella folding shaft control device, which consists of an umbrella crown base, a fastener, a controller, a controller inner core, a shifting block, a torsion spring, arotary disc, a coiled spring and a rotary disc pull rope. As the control device is equipped with the rotary disc which is connected with a lower nest via the rotary disc pull rope and the shifting block is engaged with ratchet teeth on the peripheral wall of the rotary disc, the shaft can be stopped at any position when folding the umbrella, and then hurt to users caused by fast opening again ofthe shaft under rebound force of a shaft spring during a folding process of the umbrella can be avoided.

Description

Excellent control device in closing one's umbrella

Technical field

The utility model relates to a kind of parachute kit, particularly relates to excellent control device in a kind of the closing one's umbrella.

Background technology

En-toutcas is widely used in the daily life.Many foldings open en-toutcas automatically because it is easy to use, be convenient to take in and be subjected to liking of users deeply.It mainly is to be made of parts such as sub warhead, shell fragment, button, umbrella headstocks that the receipts of commonly using automatic receipts parachute-opening are opened control assembly, when closing one's umbrella, fastens sub warhead by parts such as shell fragments, and parachute kit is folded.This parachute kit of commonly using is in the process of folding, automatically closed one's umbrella in order to give, the middle excellent spring energy-storage of parachute-opening, need be pressed into middle rod in the umbrella handle fully, can will descend nest to block, in case in the process that presses down, slip out of the hand then parachute kit can open once again fast under the effect of the screen resilience of middle excellent spring, and may injure the user.Because this parachute kit of commonly using is received and opened control assembly in the process of closing one's umbrella, following nest can't rest on the optional position, and the user uses very inconvenient, even damages to the user.

The utility model content

The purpose of this utility model be to provide a kind of security performance better close one's umbrella in excellent control device, down nest can rest on the optional position in the process of closing one's umbrella.

For achieving the above object, technical solution of the present utility model is:

The utility model is an excellent control device in a kind of the closing one's umbrella, and it is mainly by umbrella headstock, discount, controller, controller inner core, shifting block, torsion spring, rotating disk, coiled springs and rotating disk stay cord; Described controller is a tubular element, fixedly is nested with in the longitudinal hole of umbrella headstock; Described controller inner core is a tubular element, and activity is located in the hollow pipeline of controller; Described discount upper end connects parachute lanyard, the lower end is movable to penetrate the top of hollow pipeline of controller and the upper surface that its lower surface leans the controller inner core in being arranged in the hollow pipeline of controller, and the lower surface of controller inner core passes the lower port of controller; Described rotating disk is a disc-shaped component with middle part deep gouge, on its circumferential wall, offer a plurality of ratchets and around the winding slot of full perisporium, rotating disk is rotating to be socketed in the rotating shaft that umbrella headstock bottom is convexly equipped with, coiled springs is nested with in the circular deep gouge in the middle part of rotating disk, the two ends of coiled springs are articulated in respectively on the cell wall of rotating shaft and rotating disk deep gouge, form a flexible drive power of ordering about rotating disk around the rotating shaft rotation; Described shifting block by bearing pin can swing be installed on the umbrella headstock and below the controller lower port and between the rotating disk, socket torsion spring on shifting block and bearing pin, the last free end of shifting block leans with the lower surface that passes the controller inner core of controller lower port, the following free end of shifting block can abut against on the circumferential wall of rotating disk and can with the ratchet clamping on the circumferential wall; Described rotating disk stay cord is wrapped on the winding slot of rotating disk, and the one end passes the last nest of the hollow pipeline connection parachute kit of controller.

Offer four ratchets on the described rotating disk circumferential wall.

After adopting such scheme, because the utility model has been set up a rotating disk that is connected with following nest by the rotating disk stay cord, by cooperating of the ratchet on shifting block and the rotating disk circumferential wall, rod can rest on the optional position in making when parachute kit folds, this has effectively prevented to fold in the process at parachute kit, and middle rod opens the injury that causes to the user once again fast under the effect of the screen resilience of middle excellent spring.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

The specific embodiment

As shown in Figure 1, the utility model is an excellent control device in a kind of the closing one's umbrella, and it is mainly by umbrella headstock 1, discount 2, controller 3, controller inner core 4, shifting block 5, torsion spring 6, rotating disk 7, coiled springs 8 and rotating disk stay cord 9.

Described controller 3 is a tubular element, fixedly is nested with in the longitudinal hole 11 of umbrella headstock 1; Described controller inner core 4 is a tubular element, and activity is located in the hollow pipeline 31 of controller 3; Described discount 2 upper ends connect parachute lanyard 101 (as shown in Figure 6), the lower end is movable to penetrate the top of hollow pipeline 31 of controller 3 and the upper surface that its lower surface leans the controller inner core 4 in the hollow pipeline 31 that is arranged in controller 3, and the lower surface of controller inner core 4 passes the lower port 32 (as shown in Figure 3) of controller 3; Described rotating disk 7 is a disc-shaped component with middle part deep gouge 71, on its circumferential wall, offer four ratchets 72 and around the winding slot 73 of full perisporium, rotating disk 7 is rotating to be socketed in the rotating shaft 12 that umbrella headstock 1 bottom is convexly equipped with, coiled springs 8 is nested with in the circular deep gouge 71 at rotating disk 7 middle parts, the two ends of coiled springs 8 are articulated in respectively on the cell wall of rotating shaft 12 and rotating disk 7 deep gouges 71, form a flexible drive power of ordering about rotating disk 7 around rotating shaft 12 rotations; Described shifting block 5 by bearing pin 51 can swing be installed on the umbrella headstock 1 and below controller 3 lower port 32 and between the rotating disk 7, socket torsion spring 6 on shifting block 5 and bearing pin 51, the last free end of shifting block 5 leans (as shown in Figure 2) with the lower surface that passes the controller inner core 4 of controller 3 lower port 32, the following free end of shifting block 5 can abut against on the circumferential wall of rotating disk 7 and can with ratchet 72 clampings on the circumferential wall; Described rotating disk stay cord 9 is wrapped on the winding slot 73 of rotating disk 7, and the one end passes the last nest 102 of the hollow pipeline 31 connection parachute kits of controller 3.
