Abstract

The utility model discloses a firmer umbrella, which comprises an umbrella framework, a plastic sleeve, an upper runner, a middle groove, a compression spring, a lower runner and a middle bar. The inner ends of the umbrella framework are respectively hinged onto the upper runner, the middle groove and the lower runner; the upper runner, the middle groove and the lower runner are sequentially arranged on the middle bar; the compression spring is sleeved on a section extending downwards of the middle groove; two ends of the compression spring are respectively abutted to the middle groove and thelower runner; the plastic sleeve is sleeved on the middle bar and positioned between the upper runner and the middle groove. By adding the plastic sleeve to a conventional umbrella and employing thepressure of the spring, the firmer umbrella has the advantages that iron sheet bayonets need not be arranged on umbrella ribs, thereby working procedures are saved. Besides, the firmer umbrella without adopting a comparatively thick umbrella framework (16 K umbrella) can achieve nearly the same wind-resistance performance as an umbrella with the comparatively thick umbrella framework (16 K umbrella), thereby the firmer umbrella saves raw materials and has comparatively high performance-price ratio.

Description

More firm parachute kit

Technical field

The utility model relates to a kind of parachute kit, particularly relates to a kind of more firm parachute kit.

Background technology

The parachute kit of commonly using comprises umbrella frame frame, last nest, middle groove, compression spring, following nest, middle rod; The inner of described umbrella frame frame is hinged on nest, middle groove respectively, down on the nest, last nest, middle groove, down nest in regular turn on the rod, during the compression spring housing is connected on the downward extension of groove, the two ends of compression spring lean respectively on middle groove and following nest.If this parachute kit commonly used adopts the umbrella frame frame (16K umbrella) than unsawn timber matter, the cost height of umbrella then, middle excellent plastic sheath is too close to be split easily, makes the spring spring life of its generation shorter after pressure is big; If adopt the umbrella frame frame (12K umbrella) of thin material, then wind resistance is lower;

The utility model content

The purpose of this utility model is to provide the parachute kit that a kind of wind resistance is strong, cost performance is higher, more firm.

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

The utility model is a kind of more firm parachute kit, and it comprises umbrella frame frame, last nest, middle groove, compression spring, following nest, middle rod; The inner of described umbrella frame frame is hinged on nest, middle groove respectively, down on the nest, last nest, middle groove, down nest in regular turn on the rod, during the compression spring housing is connected on the downward extension of groove, the two ends of compression spring lean respectively on middle groove and following nest; It also comprises a plastic pipe sleeve, and this plastic pipe sleeve is socketed on the middle rod and between last nest and middle groove.

After adopting such scheme, because the utility model is to have increased by a joint plastic bushing at the parachute kit umbrella of commonly using, quote the pressure of spring, not needing on the umbrella frame has the iron plate bayonet socket again, has saved operation.Need not to adopt thicker umbrella frame frame (16K umbrella), it is basic identical with thicker umbrella frame frame (16K umbrella) that wind resistance just can reach, and saves raw material, and cost performance is higher.

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

Description of drawings

Fig. 1 is an exploded view of the present utility model;

Fig. 2 is an installation diagram of the present utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model is a kind of more firm parachute kit, and it comprises umbrella frame frame 1, last nest 2, plastic pipe sleeve 3, middle groove 4, compression spring 5, following nest 6, middle excellent 7.

The inner of described umbrella frame frame 1 is hinged on respectively on nest 2, middle groove 4, the following nest 6.Described going up on nest 2, middle groove 4, the middle in regular turn rod 7 of following nest 5, plastic pipe sleeve 3 is socketed on the middle rod 7 and between last nest 2 and middle groove 4.On the downward extension 41 of groove 4, the two ends of compression spring 5 leaned respectively on middle groove 4 and following nest 5 during compression spring 5 was socketed in.

Operation principle of the present utility model:

After parachute kit was opened, middle groove 4 leaned in the lower surface of plastic pipe sleeve 3 under the elastic force effect of compression spring 5, and the upper surface of plastic pipe sleeve 3 leans on last nest 2.

Emphasis of the present utility model just is: increase a plastic pipe sleeve.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.

Claims

1, a kind of more firm parachute kit, it comprises umbrella frame frame, last nest, middle groove, compression spring, following nest, middle rod; The inner of described umbrella frame frame is hinged on nest, middle groove respectively, down on the nest, last nest, middle groove, down nest in regular turn on the rod, during the compression spring housing is connected on the downward extension of groove, the two ends of compression spring lean respectively on middle groove and following nest; It is characterized in that: it also comprises a plastic pipe sleeve, and this plastic pipe sleeve is socketed on the middle rod and between last nest and middle groove.
