Abstract

The utility model provides a sliding sleeve for an umbrella and is mechanically scarfed as a whole by a lower nest block 10, a long pipe 20 and a drive body 30. The overall length of the scarfed sliding sleeve is longer than the traditional sliding sleeve because the long pipe 20 is adopted, so that operation of opening and folding the umbrella is convenient, and the sliding sleeve is in particularly applicable to the umbrella or gingham with a birdcage shaped umbrella fabric.

Description

Sliding sleeve for umbrella

The present invention relates to a sliding sleeve for an umbrella, and more particularly to a sliding sleeve for an umbrella, which is formed by joining a lower nest block, a pushing body and a long tube so as to unfold or fold an umbrella cover.

The traditional sliding sleeve is formed by integrally combining a lower nest for embedding a branch bone, a short tube part and a pushing part.

The disadvantages of such sliding sleeves are: the umbrella is required to be frequently held between the buckle and the sliding sleeve by fingers, but the buckle is usually a sheet-shaped protrusion and has a sharp feeling, so that the umbrella feels uncomfortable when the sliding sleeve is released by pressing the buckle by the umbrella, and particularly feels uncomfortable when the spring force is strong, and in addition, the cut end of the iron wire connected with the support rib is sharp and protruded, so that the fingers of the umbrella are easy to be stabbed.

The major disadvantage is that the conventional sliding sleeve has a short total length, usually about 5-6 cm short, and when the umbrella is used by children, the umbrella is in a birdcage shape, and the operation is difficult and inconvenient, because the umbrella cover is unfolded or retracted and the user has to put his hand deep into the umbrella, i.e. near the upper nest.

The utility model aims at providing a microscler is sliding sleeve for umbrella, need not with the umbrella person with the hand deep stretch into in the umbrella alright accomplish the expansion of umbrella face easily or receive the receipts and close the operation to also there is not the rib iron wire pointed end to stab the finger, the sliding sleeve who is particularly suitable for birdcage form umbrella face to use.

In order to achieve the above object, the applicant provides a sliding sleeve for umbrella, which is formed by a lower nest block, a pushing body and an elongated tube, wherein the lower nest block comprises a lower nest portion and a short tube portion integrally formed at the lower portion of the lower nest portion and provided with an annular protrusion, an axial through groove and a small protrusion for stopping;

the pushing body comprises a pushing block and short pipe parts which are integrally formed at the upper part of the pushing block and are provided with annular positioning protrusions, axial through grooves and small stopping protrusions, the long pipe is provided with a notch which has a diameter slightly larger than that of each short pipe part and is provided with openings at the upper end and the lower end of the notch in a cutting mode and can be embedded with each small protrusion, and annular protruding rings which can be respectively embedded with the annular protrusions are formed on the peripheral surfaces of the upper end and the lower end of the notch.

Because the utility model adopts the above structure, need not with the umbrella man and stretch into the interior alright completion umbrella face's expansion easily or receive the receipts operation deeply of hand to also need not worry that the iron wire pointed end stabs the finger, be particularly suitable for the sliding sleeve that birdcage form umbrella face used.

The invention will be further described with reference to the following figures and examples: wherein,

fig. 1 is a partially cut-away front view of a sliding sleeve according to the present invention;

FIG. 2 is an exploded front view of the sliding sleeve;

first, the sliding sleeve of the present invention is described below with reference to fig. 1 and 2:

as shown in figures 1 and 2, 10 is a lower nest block, the upper part of the lower nest block 10 is a lower nest part 11 for inserting and holding umbrella ribs, and the lower nest part 11 is the same as the lower nest of a common traditional umbrella. A short tube part 12 having an inner diameter slightly larger than the outer diameter of the stem 2 is integrally formed at the lower part of the lower nest part 11, and a pair of positioning projections 13 are formed on the tube peripheral surface at the substantially center of the short tube part 12 so as to face each other. A small stopper protrusion 15 is formed at the boundary between the lower nest portion 11 and the short tube portion 12 and between the pair of protrusions 13.

The pushing body 30 comprises a pushing block 31, a short pipe 12 of the lower nest block 10 which is formed integrally with the pushing block and has a shape and a structure, and a short pipe part 32 which is arranged symmetrically with the short pipe part. Wherein 33 is a positioning protrusion, and 35 is a small stopping protrusion. 20 is a long tube, the inner diameter of the long tube 20 is slightly larger than the outer diameter of the short tube 12 of the lower nest block 10 to allow the short tube 12 to be inserted into the upper end of the long tube 20.

A pair of elongated fitting holes 21 are formed on the peripheral surfaces of the upper end and the lower end of the elongated tube 20 so as to face each other, and a notch 22 for fitting the

small projections

15, 35 is cut in the opening edge of the upper end and the lower end of the elongated tube 20.

Fig. 1 shows the sliding sleeve of the present invention assembled and integrated by the

components

10, 20, 30 shown in fig. 2.

The assembly mode is as follows:

the short pipe part 12 of the lower nest block 10 is inserted with its small projection 15 aligned with the notch 22 of the upper opening of the elongated tube 20, and then the short pipe part of the lower nest block 10 is pushed into the elongated tube 20 by force until the small projection 15 is inserted into the notch 22 of the elongated tube 20. At this time, the projection 13 on the peripheral surface of the short tube 12 of the lower nest 10 is fitted into the fitting hole 21 of the long tube 20, and thus the lower nest 10 is joined to the upper end of the long tube 20 without rotating.

The method of engaging the short tube part 32 of the pusher 30 with the lower end of the long tube 20 is the same as that of the above-described lower nest block 10 with the long tube 20, and therefore, the description thereof will not be repeated.

In order to press the short pipe portions 12 and 32 into the elongated pipe 20, longitudinal through grooves 34 may be formed on the peripheral surfaces of the short pipe portions 12 and 32 to radially reduce the diameters of the short pipe portions 12 and 32 for facilitating engagement. The through-grooves 34 are formed at positions opposed to the peripheral surfaces of the short pipe portions 12, 32.

Because the sliding sleeve of the utility model has the structure, when the umbrella face is opened and closed, the user can conveniently grasp the pushing body 30 and can easily operate without extending the hand deep into the umbrella, thus being particularly suitable for the umbrella or the umbrella with the umbrella cover of the birdcage umbrella.
