In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an electronic umbrella wire wheel, includes the wheel body, the wire groove has been seted up around the round to the outer terminal surface of wheel body, wire groove opposite bilateral symmetry is provided with the bellying that links into an integrated entity, and the multiunit bellying of same one side is end to end annular array in proper order, bellying middle part is inwards sunken, the bellying slope of wire groove opposite both sides sets up acute angle alpha.

Preferably, the side wall of the wheel body is fixedly connected with a turbine with aligned axes.

Preferably, the angle α is 30 °.

Preferably, the middle part of the protruding part is recessed inwards to form an arc surface.

Preferably, a distance b is arranged between the same ends of the two groups of symmetrically arranged protruding parts, which are close to each other.

Compared with the prior art, the utility model has the beneficial effects that: the side wall of the wire groove of the wheel body is provided with the bulge parts which are connected into a whole, the bulge parts on the two opposite sides are inclined at an acute angle, and the friction force between the bulge parts and the rope is improved.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model provides an electronic umbrella wire wheel, includes wheel body 1, wheel body 1 outer terminal surface circle has seted up wire groove 3, wire groove 3 opposite bilateral symmetry is provided with the bellying 2 that links into an integrated entity, and the multiunit bellying 2 of same one side end to end annular array in proper order, bellying 2 middle part inwards sunken, and bellying 2 slope in wire groove 3 opposite both sides sets up acute angle alpha.

Further, the side wall of the wheel body 1 is fixedly connected with a turbine 4 with aligned axes.

Further, the angle α is 30 °.

Further, the middle part of the protruding part 2 is recessed inwards to form an arc surface.

Further, a distance b is provided between the same ends of the two groups of symmetrically arranged protruding portions 2, which are close to each other.

One embodiment of the utility model:

the rope passes through the wire groove 3, and opposite sides of the outer side wall of the rope are respectively abutted with the protruding parts 2 on two sides of the wire groove 3, and friction force between the wheel body 1 and the rope is improved through the protruding parts 2.

The protruding portions 2 of the two circles of annular arrays are symmetrically arranged, an included angle alpha is formed between the two groups of protruding portions 2 of different groups of symmetry and is set to be an acute angle, the included angle alpha is set to be 30 degrees, a distance b is reserved between one ends, close to each other, of the protruding portions 2 of the two groups of symmetry, and when the outer diameter of a rope is smaller, the rope can be abutted to the two groups of protruding portions 2 and the three places of the bottom wall of the wire groove 3 at the same time, so that friction force is improved.
