Description

Three fold automatic umbrella

The utility model relates to an automatic umbrella, in particular to a three-fold automatic umbrella.

Umbrellas are widely used. Whether they are used for sunshade or rain protection, they are a convenient and practical daily necessities. In pursuit of both exquisite and practical umbrellas, they have progressed from the previous straight umbrellas and folding umbrellas to the present. The smallest three-fold umbrella. As shown in Figure 1, it is a common three-fold automatic umbrella 10. The upper, middle and lower nests 12, 13 and 14 are set on the umbrella backbone 11. The umbrella opening springs 15, 16 between the upper nest 12 and the middle nest 13 and the middle nest 13 and the lower nest 14 promote the middle nest 13 and the lower nest 14, and then affect the umbrella frame branch 17 to support the umbrella cover. When the umbrella is closed, because the opening springs 15 and 16 are arranged on the outside of the umbrella bone trunk 11, this position will be in a relatively wide and thick umbrella closing state, which is inconvenient to store in the bag, and the exposed opening springs 15 and 16 It also affects the aesthetics.

As shown in Figures 2 to 4, it is another foldable automatic umbrella 20, which is mainly composed of an umbrella rib structure that is jointly pivoted on the upper, middle and lower nests 21, 22 and 23 and can be linked to open the umbrella surface 24. 25, wherein the upper nest 21 is fixedly arranged on the upper end of an outer tube 26, and the middle nest 22 is sleeved on the outer tube 26, and the wall of the outer tube 26 is provided with a long hole-shaped actuating slot 261, and a latch 27 pierces through the perforation 222 at the lower end of the middle nest 22 sleeve pipe 221, and passes through the actuating slot 261, so that the middle nest 22 can move up and down on the outer tube 26, and an outer tube 26 above the latch 27 is provided with a Umbrella opening spring 28; when the umbrella is closed, as shown in Figure 4, the middle nest 22 is moved upwards by the influence of the umbrella rib structure 25, and at the same time drives the latch 27 upwards and compresses along the actuating slot 261 The parachute spring 28, and when the umbrella surface is stretched (as shown in Figure 3), the parachute spring 28 releases potential energy, promotes the latch 27 at the lower end of the middle nest 22 to make the middle nest 22 move downwards, and quickly Open an umbrella. Although the above-mentioned structure can make the parachute opening spring 28 embedded in the outer tube 26, it still has the following disadvantages:

1. The automatic umbrella 20 must push the latch 27 to move along the actuating slot 261 when the potential energy is released by the umbrella opening spring 28, so that the middle nest 22 can move down to complete the action of opening the umbrella. Therefore, the outer tube The actuation slot 261 of considerable length on the pipe wall of 26 causes the structure of this section of outer pipe 26 to be damaged, thereby reducing the bending and shearing strength of itself. 26 is very likely to be bent and deformed at the actuating slot 261.

Two, because the outer tube 26 is directly fixedly connected with the upper nest 21, the parachute opening spring 28 can only produce a downward stretch or compression variation to push the middle nest 22, so if a larger spring variation is used to produce more When the energy of the umbrella is large, the actuating slot 261 will inevitably increase, which will make the strength of the outer tube 26 worse.

The main purpose of the utility model is to provide a three-fold automatic umbrella with a built-in and reduced volume umbrella opening spring, and the main structure of the umbrella frame of the umbrella will not be damaged and the components are simple.

Another purpose of the utility model is to provide a three-fold automatic umbrella which can be opened more quickly and smoothly.

In order to achieve the above purpose, the utility model provides a three-fold automatic umbrella, which includes an outer tube and an inner tube that are socketed together. The outer tube is sequentially provided with a lower nest, a middle nest and an upper nest from bottom to top. , the outer tube is provided with a parachute opening spring; it is characterized in that: the parachute opening spring is set in the upper section of the outer tube, and its bottom end is stopped by a stop element set on the outer tube; the lower nest pivot is set outside on the tube, while the middle nest is fixedly arranged on the upper end of the outer tube, and a limit bar protrudes from the bottom of the upper nest, and the limit bar penetrates the parachute spring and extends downward to the inside of the outer tube.

In the utility model, a stop element is arranged on the outer tube of the umbrella bone trunk, and an umbrella opening spring is arranged above the stop element inside the outer tube. The relative displacement of the middle nest fixed on the outer tube is used to assist in the action of opening the umbrella, so that the structure of the outer tube will not be damaged, while maintaining its bending and shear strength, and the built-in umbrella opening In addition to making the umbrella more beautiful, the spring also reduces the volume of the umbrella after it is folded, which is convenient for storage and carrying.
