Abstract

The utility model relates to an upper guide wheel group of a multi-fold automatic opening-closing umbrella; primarily, three small pulleys are fixed to an upper guide wheel base, wherein, a small pulley is fixed to the upper parts of the other small pulleys. The upper guide wheel group is applied to a four-fold or a multiple-fold automatically opening or closing umbrella; when an umbrella is in the state of closing, a rope guided by the upper guide wheel group is pulled by a lower nest to maintain a straight shape; simultaneously, the rope is pulled apart by the two small pulleys at the lower part; the utility model prevents the rope from touching to the tube wall of an outer tube in opening the umbrella, which ensures the normal movement of the rope. In addition, the two increased small pulleys can play a certain slide function, which reduces slide friction of the rope in opening the umbrella.

Description

The upper block group of many folding automatic umbrella folding and unfoldings

The utility model relates to the technical field of automatic umbrella folding and unfolding, and is relevant with the upper block group structure of many foldings automatic umbrella folding and unfolding.

Common automatic umbrella folding and unfolding, mostly be two foldings, three folding or four foldings, wherein, four folding automatic umbrella folding and unfoldings are because of under its umbrella closing state, upper and lower nest bundling trough position is than the weak point of two foldings or three folding automatic umbrella folding and unfoldings, and under the deployed condition, the length of the length of umbrella and two foldings or three folding automatic umbrella folding and unfoldings is similar, so, rope yarn must be cemented in down on the nest through the upper block in the outer tube, as shown in Figure 1, so that under its umbrella closing state, rope yarn can be guided through upper block, be kept stretching shape by following nest drawing.

But, to open on the process that closes one's umbrella actual, rope yarn is also usually run into the tube wall of outer tube in aforementioned upper block guiding, influenced the proper motion of rope yarn.

The purpose of this utility model is in the upper block group that a kind of many folding automatic umbrella folding and unfoldings are being provided, so that rope yarn is in opening the process that closes one's umbrella, the unlikely tube wall of running into outer tube guarantees the proper motion of rope yarn.

For reaching above-mentioned purpose, the utility model is rolled over the upper block group of automatic umbrella folding and unfolding more, mainly is fixed on the upper block seat by three truckles and forms; One of them truckle is fixed on the top of two other truckle.

After adopting said structure, the rope yarn of four foldings or more folding automatic umbrella folding and unfoldings can be cemented in down on the nest through behind three truckles of upper block group----in the outer tube again.Like this, under umbrella closing state, rope yarn can be guided through the upper block group, be kept stretching shape by following nest drawing; Simultaneously, two truckles by the below separate rope yarn, have avoided opening when closing one's umbrella, and rope yarn is run into the tube wall of outer tube, has guaranteed the proper motion of rope yarn; In addition, two truckles of increase also can play certain slip effect, reduce the force of sliding friction of opening rope yarn when closing one's umbrella.

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

Fig. 1 is the upper block structural representation of existing four folding automatic umbrella folding and unfoldings;

Fig. 2 is that the utility model is applied to the structural representation one of four foldings during automatic umbrella folding and unfoldings;

Fig. 3 is that the utility model is applied to the structural representation two of four foldings during automatic umbrella folding and unfoldings.

See also shown in Fig. 2-3, the utility model is that example describes to be applied to four folding automatic umbrella folding and unfoldings.The utility model mainly is fixed on the upper block seat by three truckles 1,2,3 and forms, and wherein, the slightly larger in diameter of truckle 1 is in the diameter of truckle 2,3, and truckle 1 is fixed on the top of two truckles 2,3.

During the actual use of the utility model, under umbrella closing state, rope yarn 4 can be through truckle 2,1,3 guidings, keep stretching shape by nest 5 drawings down; Simultaneously, by two truckles 2,3 separately, avoid rope yarn 4 opening the tube wall of running into outer tube 6 when closing one's umbrella, guaranteed the proper motion of rope yarn 4 rope yarn 4; In addition, the truckle 2,3 of increase also can play certain slip effect, reduces the force of sliding friction of opening rope yarn 4 when closing one's umbrella.

The utility model also can be applicable in many folding automatic umbrella folding and unfoldings, and its principle is identical with effect, does not repeat them here.

Claims

1, a kind of upper block group of many folding automatic umbrella folding and unfoldings is characterized in that: mainly be fixed on the upper block seat by three truckles and form; One of them truckle is fixed on the top of two other truckle.
