Abstract

The utility model discloses a folding telescopic cup which belongs to daily living appliances. An elastic folding cup wall is composed of a folding cylinder which is manufactured by the telescopic structure of the sound box of an accordion being imitated by the utility model and an allocated pressure spring. The folding cylinder of the elastic folding cup wall is made of nontoxic heat resisting nonosmosis high intensity flexible materials. The lower end and the upper end of the elastic folding cup wall are respectively a cup bottom and a cup opening, and the elastic folding cup wall, the cup bottom and the cup opening are integral structures. When the utility model is carried and conserved, a cup bundle and the cup bottom are separated, a cup cover is covered, pressure is applied between the cup cover and the cup bottom to screw the knob of the cup cover to make the cup cover locked and closed, and the cup bundle is turned and shortened to be fitted with the camber of the cup opening. The utility model has the advantages of firm and durable structure, low cost and convenient carrying.

Description

Expandable and contractible folded cup

The Foldable telescopic cup belongs to a kind of daily life tools.

Present cup tool on the market, its volume and profile are fixed, and this can bring certain inconvenience for traveller and the staff who goes on business and often flow.

The objective of the invention is to provides a kind of dependable performance to be easy to carry and telescopic cup tool easy and simple to handle to above-noted persons.

See also accompanying drawing:

By the bowl cover of figure shown in (1), by turn-knob 1, bowl cover main body 2, form 3; 1 and 3 is whole, 3 bottom is similar with " split pin ", 3 from the hole, garden of 2 central authorities, load after again with two parts of 3 bottoms respectively to each 90 ° of two Edge Bends, become the shape among the figure, 3 top and 2 following adjacent are fluted, the structure that embeds steel elastic collet 15(15 in groove is similar fully to " movable joint " locking plate principle of bicycle chain), 1 can rotate about, when turn 1,3 also rotate together, 2 making material can be selected steel, stainless steel, aluminium alloy or non-toxic plastic for use, and 1 and 3 should make of metal.

By the rim of a cup shown in the figure (2), rim of a cup 4 is whole with the upper end of wall of cup part in succession, and binding site should secure seal, 4 of the right is its cutaway views, its inner breach 16 is inlayed the folding wall of cup 10 of elasticity, upper edge 10 is carried out pressing be equipped with senior heatproof adhesive (product of adhensive factory, new Bin County Xinjing, northeast) after embedding 16 after again, a side of 4 with a closing-up cup frame 5, but can not " rivet ", must be behind the riveting jail can be standard for " rotating shaft " turn with rivet with 5.(as the right 5 Shown in)

By the cup handle shown in the figure (3), cup is being formed by

last joint

6 and 7 " sockets " of following joint, 6 upper end is rolled into " garden tubular " (shown in 6 on the right of figure), 6 embed wearing even with " split pin " and plain washer in the frame 5, what the company of wearing was appropriate 6 can be that rotating shaft is freely rotated with the split pin, split pin is with orthogonal the rivet on the frame 5, so the appropriate cup of the company of wearing has two " rotational freedoms " to 6,6 lower end is the straight tube 17 that is rectangle, cup is after joint 7 penetrates 17 down, make 7 can not from 17, withdraw from 7 upper end bending again, thereby realize " socket " between 7 and 6, want suitably in " gap " between 17 and 7, keeps " closely " of socket not become flexible as far as possible and exaggerate, with 7 can be in 17 smoothly about " pulling " be standard, (as 17 and 7

Shown in), 7 lower end has below " elasticity breach " 8,8 Represent that whole cup is the rotation direction of rotating shaft around split pin to combination (6 and 7 combinations).

By the folding wall of cup 10 of the elasticity shown in the figure (4), 10 by heat-resisting, nontoxic, water is not had permeability and the higher flexible material (available special fine canvas or nonpoisonous plastic film) of mechanical strength copy the folding tube that the accordion audio amplifier makes and be equipped with compression spring and make, compression spring can be divided into " one-piece type " and " divergence type " with combining of folding tube, so-called " one-piece type ", be that spring and folding tube are processed into overall structure, " the external edge edge " the 18th of folding tube, the position of inlaying spring, so the outer 18 of the folding tube of this kind must be " helix " type.

So-called " divergence type ", be meant that compression spring structurally is not connected mutually with folding tube, irrelevant mutually, so " helix " type needn't be processed in the outer 18 of the folding tube of this kind, can be considered as is the accordion sound box type structure that cross section is garden shape, and compression spring is enclosed within folding tube outside, the two is independent of each other when compression and elongation, but compression spring must be among " clamping " at the rim of a cup 4 and the cup end 11, so on physical dimension, the internal diameter of compression spring is slightly larger than the external diameter of the outer 18 of folding tube, the external diameter of compression spring must be less than the rim of a cup 4 and the diameter at the cup end 11, when assembling this kind wall of cup, must earlier compression spring be set in behind the folding tube again at the bottom of the mounting cup 11,11 and wall of cup 10 between should adopt bonding mode, (shown in the accompanying drawing is the outline drawing of " one-piece type " wall of cup), the elastic force of (" divergence type " diagram is omitted) compression spring should be selected suitably, and the elastic steel strip of available φ 3 ± 0.5 is made.

By the cup end shown in the figure (5), by main body at the bottom of the cup 11, cup is formed card 9 and breach Suo Yong 12, the three is an overall structure, and the whole cup end 11 also is the overall structure that the jail connects and seals with wall of cup 10 and rim of a cup 4, radially open the breach 14 of two " horn mouth " shapes on breach Suo Yong 12, what link to each other with 14 " turning round " is that 13, two 13 in two lock roads are " rotation symmetry " along central rotating shaft.

Figure (6) is the outline drawing that fits together with rim of a cup, the folding wall of cup of elasticity, the cup end, cup.

Rim of a cup, the optional and bowl cover identical materials making in glass, glass end.

When using this glass tool, wall of cup 10 is " elongation " state under the effect of the elastic force of compression spring, rotates cup making elasticity breach 8 aim at cup card 9, and the length of adjusting then between 6 and 7 is pressed to cup blocking 9 with breach 8, thereby make 9 to embed in the breach 8, can use.

The effect of cup handle has except its traditional function, also plays fixed volume, prevents that wall of cup from comprehensively causing the spilling water accident under unexpected pressure.(so the gap between 17 and 7 can not be excessive)

Collect and carry: this glass tool is starting from 98 after finishing, apply pressure at right angle at bowl cover 2 and cup then at the end 11, turn 1, make 3 to embed in the loudspeaker breach 14, along clockwise direction turn 1, make 3 to lock in 13, make edge " rivet rotating shaft " turn (this moment, cup rotated frame 5 together) cup being in same cross-section location in cup again with rim of a cup, shorten 6 and 7 relative distance again, make whole cup coincideing with the cambered surface of rim of a cup 4.(opening the process and the said process contrary of this glass tool)

This glass tool is compared to have with tradition cup tool and is easy to carry, and is sturdy and durable, the advantage that anti-seismic performance is strong, and also cost is cheaper.
