Abstract
The utility model discloses a rebound prevention device of an automatic opening and closing umbrella, which mainly comprises an umbrella headstock, a bullet bead, a tube, an arrester, a brake spring, a rope collecting wheel, a rewind spring and a rebound prevention cord. Because the utility model adds the rope collecting wheel which is connected with an upper cavity through the rebound prevention cord and through the match of the arrester and the ratchet on the peripheral wall of the rope collecting wheel, a middle rod can be stopped at any position when an umbrella is closed, and as a result, users can be effectively prevented from being hurt because the middle rod is rapidly opened again under the action of the resilience force of a middle rod spring when the umbrella is closed or misoperation is carried out.
Description
Technical field
The utility model relates to a kind of parachute kit, particularly relates to the anti-empty device of a kind of automatic opening and closing umbrella.
Background technology
En-toutcas is widely used in the daily life.Folding from opening en-toutcas 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 is to provide the better automatic opening and closing umbrella of a kind of security performance to prevent the empty device, and nest can rest on the optional position down in the process of closing one's umbrella, and can normally open after waiting to reset.
For achieving the above object, technical solution of the present utility model is:
The utility model is the anti-empty device of a kind of automatic opening and closing umbrella, and it mainly is made up of umbrella headstock, sub warhead, keyholed back plate, brake, tripping spring, receipts rope sheave, clockwork spring and anti-empty stay cord; Described keyholed back plate is a tubular element, fixedly is nested with in the longitudinal hole of umbrella headstock; Described sub warhead upper end connects parachute lanyard, the movable top that penetrates the hollow pipeline of keyholed back plate, lower end; Described receipts rope sheave 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, receive that rope sheave is rotating to be socketed in the rotating shaft that umbrella headstock bottom is convexly equipped with, clockwork spring is nested with in the circular deep gouge in the middle part of receiving rope sheave, the two ends of clockwork spring are articulated in rotating shaft respectively and receive on the cell wall of rope sheave deep gouge, form one and order about the flexible drive power of rope sheave around the rotating shaft rotation of receiving; One end of described brake is by being installed on the umbrella headstock that bearing pin can be swung, socket tripping spring on brake and bearing pin, the last free end of brake with penetrate keyholed back plate the sub warhead lower surface lean, the following free end of brake can abut against on the circumferential wall of receiving rope sheave and can with the ratchet clamping on the circumferential wall; Described anti-empty stay cord is wrapped on the winding slot of receiving rope sheave, and the one end passes the last nest of the hollow pipeline connection parachute kit of keyholed back plate.
Offer four ratchets on the described receipts rope sheave circumferential wall.
After adopting such scheme, because the utility model has been set up a receipts rope sheave that is connected with last nest by anti-empty stay cord, by brake with receive the rope sheave circumferential wall on the cooperating of ratchet, rod can rest on the optional position in making when parachute kit folds, this has effectively prevented to fold in the process or because of maloperation at parachute kit, in rod under the effect of the screen resilience of middle excellent spring, open the injury that causes to the user once again fast, normally open, need wait closes one's umbrella can carry out after resetting.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 2 is that the utility model parachute kit begins to fold procedure chart;
Fig. 3 is the utility model parachute kit deployed condition figure.
The specific embodiment
As shown in Figure 1, the utility model is the anti-empty device of a kind of automatic opening and closing umbrella, and it mainly is made up of umbrella headstock 1, sub warhead 2, keyholed back plate 3, brake 4, tripping spring 5, receipts rope sheave 6, clockwork spring 7 and anti-empty stay cord 8.
Described keyholed back plate 3 is a tubular element, fixedly is nested with in the longitudinal hole of umbrella headstock 1; Described sub warhead 2 upper ends connect parachute lanyard 9, the movable top that penetrates the hollow pipeline of keyholed back plate 3, lower end; Described receipts rope sheave 6 is a disc-shaped component with middle part deep gouge, on its circumferential wall, offer four ratchets 61 and around the winding slot of full perisporium, receive that rope sheave 6 is rotating to be socketed in the rotating shaft 11 that umbrella headstock 1 bottom is convexly equipped with, clockwork spring 7 is nested with in the circular deep gouge in the middle part of receiving rope sheave 6, the two ends of clockwork spring 7 are articulated in rotating shaft 11 respectively and receive on the cell wall of rope sheave 6 deep gouges, form one and order about the flexible drive power of rope sheave 6 around rotating shaft 11 rotations of receiving; One end of described brake 4 is by being installed on the umbrella headstock 1 that bearing pin 40 can be swung, socket tripping spring 5 on brake 4 and bearing pin 40, the last free end 41 of brake 4 leans with sub warhead 2 lower surfaces that penetrate keyholed back plate 3, the following free end 42 of brake 4 can abut against on the circumferential wall of receiving rope sheave 6 and can with ratchet 61 clampings on the circumferential wall; Described anti-empty stay cord 8 is wrapped on the winding slot of receiving rope sheave 6, and the one end passes the last nest 10 of the hollow pipeline connection parachute kit of keyholed back plate 3.
Operation principle of the present utility model:
As shown in Figure 2, when closing one's umbrella, sub warhead 2 breaks away from the last free end 41 of brake 4, and brake 4 is under the effect of tripping spring 5, the following free end of brake 4 abut against on the circumferential wall of receiving rope sheave 6 and with circumferential wall on ratchet 61 clampings, limited the rotation of receiving rope sheaves 6.Middle rod 20 inserts in the umbrella headstocks 1, clockwork spring 7 drives receives rope sheave 6 rotations, anti-empty stay cord 8 is wrapped on the winding slot of receiving rope sheave 6, stop in case middle excellent 20 are pressed into half road, 20 resiliences under the spring force effect of middle excellent spring of middle rod, sub warhead 2 is extracted out from keyholed back plate 3, brake 4 under the effect of tripping spring 5 again holding receiving ratchet 61 on rope sheave 6 circumferential wall, rod 20 not resiliences fast in making.
As shown in Figure 3, during parachute-opening, sub warhead 2 leans the last free end 41 of brake 4 again, and the following free end of brake 4 breaks away from the ratchet of receiving on rope sheave 6 circumferential wall 61, receives rope sheave 6 and freely rotates, anti-empty stay cord 8 elongations.
