Abstract

The utility model provides a rotation controlling structure of an opening and furling driving device for an umbrella, which can drive an umbrella nest to rise or fall so as to open or furl the umbrella. A driving shaft of a gear driving unit can be further provided with a positioning hole and connected with a rotation controlling button, and then the driving shaft can be driven to rotate when the rotation controlling button is rotated, therefore, the rotation controlling structure has the advantage of convenient and precise operation and can be operated by a single hand, so that the convenience of the operation is improved.

Description

The rotation control means of driving, receive transmission device of umbrella

Technical field

The utility model is meant a kind of rotation control means of driving, receiving transmission device of umbrella, can control its rotation by rotating control knob, and is easy to operate.

Background technology

There are following disappearance in common umbrella or Western-style umbrella:

1. because be with spring control parachute-opening, when bouncing up parachute-opening fast by the fixing spring button, have people or article to damage as not noting the next door, security is not good.

2. the locating effect after the parachute-opening is relatively poor, meets with high wind especially in use and is easy to contract downwards and moves and cause user's puzzlement, even rapid-resultly damage and reduce service life.

3. because of making the parachute-opening action, elastic fatigue can't locate fully easily after using a period of time, the inventor is that prerequisite is studied and improved to solve aforementioned disappearance and to turn round easy to operate with rotation control, and creation has designed a kind of rotation control means of driving, receiving transmission device of umbrella.

The utility model content

Main purpose of the present utility model is to provide a kind of rotation control means of driving, receiving transmission device of umbrella, has easy to operate advantage accurately again, and also can change the convenience that is promoted its operation by the one-handed performance mode.

For reaching above purpose, solution of the present utility model is:

A kind of rotation control means of driving, receiving transmission device of umbrella, but be that transmission umbrella nest rises or the action of decline to reach parachute-opening or to close one's umbrella: wherein:

This umbrella nest is risen or descends by the power transmission shaft of gear drive group institute's interlock, and this drive shaft system and is rotated the control knob binding, and then the aforementioned umbrella nest of relative linked gear transmission group transmission rises or descends when the rotation control knob is rotated.

Wherein the transmission group of this gear drive group is can change into having gear part for being connected with another gear drive group, the power transmission shaft of this another gear biography group then rotates the control knob binding with one, and then can drive the power transmission shaft of this another gear drive group travelling gear transmission group when this rotation control knob is rotated relatively.

Owing to adopted above technical scheme, the utlity model has following beneficial effect:

The rotation control means of driving, receive transmission device of the utility model umbrella has easy to operate advantage accurately again, and also can change the convenience that is promoted its operation by the mode of one-handed performance, has higher utility.

The specific embodiment

As Fig. 1～shown in Figure 6, the rotation control means of driving, receive transmission device of the utility model umbrella, action to reach parachute-opening or to close one's umbrella but transmission umbrella nest 1 (with reference to figure 1, Fig. 6) rises or descends; Wherein:

This is driven, receives transmission device and comprises:

Driving screw 2 (with reference to figure 2), top spiral shell are established a driving screw nut 3 (with reference to figure 5), and its below then is provided with gear part 21 (with reference to figure 3) can be by 6 transmissions of gear drive group;

Gear drive group 6, have gear train (figure do not show) but and the power transmission shaft 61 of this gear train of transmission, and the top of this gear drive group 6 and be provided with enclosing cover 62;

Driving screw nut 3 sets firmly the locating slot 11 (with reference to figure 5) that is linked to umbrella nest 1, and it is led screw thread hole 31 and is worn by driving screw 2 spiral shells;

Rod 4 is telescopic body in flexible, and its top 41 links with the below of umbrella nest 1, and its below 42 then is that the enclosing cover 62 with gear drive group 6 links fixing;

Composition by aforementioned components, when the power transmission shaft 61 positive counter rotations of gear drive group 6 are moving, just can drive driving screw 2, contrary direction rotation, make driving screw nut 3 can rise above driving screw 2 together with the umbrella nest 1 of its binding or descend action relatively to reach parachute-opening or to close one's umbrella, and preceding described umbrella nest 1 below links flexible in rod 4 also with make progress expansion or fold downwards of the rise and fall action of work umbrella nest 1, therefore can drive 1 lifting of umbrella nest by driving screw 2 set driving screw nuts 3, can be by manually-operated soon or slowly to reach parachute-opening, have preferable security and locating effect when closing one's umbrella, have preferable anti-high wind effect relatively, and then the situation that also can reduce damage produces and improves service life.

Again, with reference to figure 4, shown in Figure 5, the power transmission shaft 61 of aforesaid gears transmission group 6 can further be provided with locating hole 611 and rotate control knob 5 by lock member 22 and and link, and then rotates relative to driving power transmission shaft 61 when rotation control knob 5 is rotated.

In addition, the enclosing cover 62 of aforesaid gears transmission group 6 can further link excellent holder 63 (with reference to figure 1) in, and the below by excellent holder 63 in this links with enclosing cover 62 again, the top of middle excellent holder 63 then with aforementioned flexible in the following ora terminalis binding of below 42 of rod 4.

Again, with reference to figure 4, aforesaid in excellent holder 63 also be provided with locating hole 631 can be further by lock member 20 and a hollow grip 7 bindings, can have aesthetic concurrently.

In addition, please cooperate reference shown in Figure 7 in addition be another embodiment of the present utility model, its principal character is identical with previous embodiment, main and the difference of previous embodiment be the transmission group 61 of aforesaid gears transmission group 6 be can change into have gear part (figure does not show) for being connected with another gear drive group (scheming not show), the power transmission shaft of this another gear drive group (figure does not show) then rotates control knob 5 ' binding with one, and then can drive the power transmission shaft 61 of this another gear rotating group travelling gear transmission group 6 when this rotation control knob 5 ' is rotated relatively.

In sum, the rotation control means of driving, receive transmission device of the utility model umbrella is to have operation side Just advantage accurately again, and also can change the convenience that is promoted its operation by the mode of one-handed performance, really have Practical value.
