Abstract

The utility model discloses a switching device of a manual operation umbrella, which comprises a lower pocket, a button, a button spring and a middle rod, wherein the center of the lower pocket is provided with a middle hole which is in socket joint with the middle rod; the radial direction along the lower pocket is provided with a transverse through groove communicated with the middle hole; the button is arranged in the through groove in a penetration form; the insertion end of the button is provided with the middle hole; the middle rod can penetrate through the middle hole; the inner wall of the middle hole is provided with a convex block which extends inwards; the middle rod is provided with a gap, and the shape and the size of the gap correspond to those of the convex block on the inner wall of the button so that the convex block can freely enter or exit; the button spring is arranged between the insertion end of the button and the inner wall of the middle hole of the lower pocket. Because the button which plays the switching action is nested in the lower pocket, the button is always pressed on the outer wall of the middle rod under the action of the button spring so that the position between the middle rod and the middle hole of the pocket, which is nested with the middle rod, has no gap. Besides, the lower pocket can not swing during sliding on the middle rod. Therefore, the umbrella is steady, easy and comfortable to open and close.

Description

The switching device of hand parachute-opening

Technical field

The utility model relates to a kind of umbrella structure, particularly relates to a kind of switching device of hand parachute-opening.

Background technology

Umbrella is one of daily life tools of people's indispensability.General hand open type folding umbrella outside the rod, having the gap between nest and the middle rod down, is subject to the basic structure form during nest button bullet section type structure under being of employing, following nest are sleeved on, and when parachute-opening, is not to present stable state between following nest and the middle rod.Therefore when high wind blew, following nest and umbrella frame frame integral body were to rock a little, cause user's puzzlement.And when closing one's umbrella, hinder hand easily, moulding is also attractive in appearance inadequately.

The utility model content

The purpose of this utility model is to provide a kind of switching device of opening the hand parachute-opening that closes one's umbrella easy, comfortable, stable, safe.

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

The utility model is a kind of switching device of hand parachute-opening, and it comprises nest, button, button spring and middle rod down; Described down nest central authorities offer the mesopore of rod in the socket, radially offer a horizontal groove that connects with mesopore, the shape of this groove, big or small and button corresponding along nest down; Described button is set in down in the groove of nest, and the insertion end of button has a mesopore that allows middle rod pass, and a projection extends internally out on the inwall of this mesopore; Described middle rod is set in down the nest mesopore and has penetrated down in the button mesopore of nest, offers a breach on middle rod, and the projection on the shape of this breach, size and the button inwall is corresponding, so that allow projection can insert or deviate from breach freely; Described button spring is arranged between button insertion end and the following nest mesopore inwall, so that rod radially applies a radial load on the button insertion end in the edge.

After adopting such scheme, because it is to be nested with in following nest that the utility model plays the button of on-off action, button is under the effect of button spring all the time on the outer wall of roof pressure at middle rod, there is not the gap between the following nest mesopore of rod in rod and the socket in making, can not swing when following nest slides on middle rod, open close one's umbrella more stable, easy and comfortable; And because the utility model is not to adopt button to play section type structure, no shell fragment can not hurt user's hand, so, use more safe and reliable.

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

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model is a kind of switching device of hand parachute-opening, and it comprises nest 1, button 2, button spring 3 and middle excellent 4 down.

Described down nest 1 central authorities offer the mesopore 11 of rod 4 in the socket, radially offer a horizontal groove 12 that connects with mesopore 11, the shape of the shape of this groove 12, size and button 2, big or small corresponding along nest 1 down; Described button 2 is set in down in the groove 12 of nest 1, the insertion end of button 2 have one allow in the rod 4 mesopores that pass 21, a projection 22 extends internally out on the inwall of this mesopore 21; Rod 4 passes down nest 1 mesopore 11 and has penetrated down in interior button 4 mesopores 21 of nest 1 groove 12 in described; Offer a breach 41 on middle excellent 4, the projection 22 on the shape of this breach 41, size and button 2 inwalls is corresponding, so that allow projection 22 can penetrate or deviate from breach 41 freely; Described button spring 3 is arranged between button 2 insertion ends and following nest 1 mesopore 11 inwalls (shown in Fig. 4 B, 4C), so that rod 4 radially applies a radial load on button 2 insertion ends, the breach 41 during the projection 22 on button 2 inwalls is headed on the rod 4 in the edge.

Operation principle of the present utility model:

Parachute-opening, upwards push nest 1 (shown in Fig. 4 A, 4B) with hand, breach 41 places of rod 4 during nest 1 is shifted onto instantly, the projection 22 on button 2 inwalls is the breach 41 (shown in Fig. 4 B, 4C) on the rod 4 in heading under the effect of button spring 3 power, to descend nest 1 fixing, parachute kit is opened.

Close one's umbrella, pin button 2 (shown in Fig. 5 A, 5B), overcome button spring 3 power with hand, make projection 22 on button 2 inwalls break away from breach 41 on the rod 4, will descend nest 1 along in rod 4 move down, parachute kit folds.

Emphasis of the present invention just is: projection on the button inwall breaks away from breach on the middle rod and cooperates, as parachute kit unlatching, the switch that folds.

Claims (1)

1, a kind of switching device of hand parachute-opening is characterized in that: it comprises nest, button, button spring and middle rod down; Described down nest central authorities offer the mesopore of rod in the socket, radially offer a horizontal groove that connects with mesopore, the shape of this groove, big or small and button corresponding along nest down; Described button is set in down in the groove of nest, and the insertion end of button has a mesopore that allows middle rod pass, and a projection extends internally out on the inwall of this mesopore; Described middle rod is set in down the nest mesopore and has penetrated down in the button mesopore of nest, offers a breach on middle rod, and the projection on the shape of this breach, size and the button inwall is corresponding, so that allow projection can insert or deviate from breach freely; Described button spring is arranged between button insertion end and the following nest mesopore inwall, so that rod radially applies a radial load on the button insertion end in the edge.
