Description

Changeable size cap

The utility model belongs to daily living article, specifically, is a kind ofly can stretch out the retractible greatly again cap of change.The style of existing cap and to make used material of all kinds, but they make rear shape size and just can not change function singleness.Existing cap is taken and is worn all and makes things convenient for, but these caps are all too little, can not satisfy the needs that the people produces sun-shading rain-proof fully.

The purpose of this utility model is and can be worn on the head as cap, and is easy to carry, again variable big, makes it sun-shading rain-proof as umbrella, can satisfy well people's requirement.

The utility model is achieved in that

Upper slip is provided with the boss with through hole; Main lower slip two ends band tack axle, middle place band tip axle and projection; Secondary lower slip one end and middle place band tack axle, other end band tip axle.The boss of last slip is pasting main slip down and is intersecting the folded mutually one group of slip group of forming, and adds by some groups of slips that two groups of crooked slips are arranged to link to each other with a definite sequence and constitutes into main expansion bracket.The boss of upper slip is pasting secondary lower slip and is forming one group of slip, and being linked to each other with certain sequence by some groups of slips consists of secondary expansion bracket.Upper cap is common sunbonnet pattern, lower cap is no top covering hat conical surface body, its conical surface body Intermediate Gray is useful on the tegmental wall circle of positioning installation swivel becket, be provided with the support framework of projection at lower cap conical surface body, be used for supporting telescoping mechanism weight, support framework is provided with the guide groove that is beneficial to the telescoping mechanism running, establishes a bar hole on the conical surface body of lower cap.

Rotate up and down ring all with hangers and gathering bar, hang extension spring at hangers, moving hook is placed on the swivel becket, arranges on another swivel becket and decides hook.Rotate up and down ring and link to each other with the crooked slip of main expansion bracket by connection shaft, main expansion bracket links to each other with secondary expansion bracket by crooked slip.Cap cloth is pierced through by the major and minor tip axle of slip down and is positioned on the telescoping mechanism, cap cloth is compressed on the tip axle with gasket sleeve, and lid is packed in the pressure pad.

Swivel becket is enclosed within on the tegmental wall circle of lower cap, and main expansion bracket places on the support framework, and the projection of slip is placed in the guide groove of support framework under the master of main expansion bracket.Upper cap sleeve covered at lower cap compress, whole cap assembling is complete.

Telescoping mechanism places in the cavity between cap and the lower cap, by the controlled hatting of telescoping mechanism magnify and diminish, the recoverable a part of cap cloth of main expansion bracket, remaining is regained by pair contracting frame.

The utility model can become and diminish greatly, become when big as the umbrella, but sun-shading rain-proof becomes hour then easy to carry as cap.

Described in detail in conjunction with the accompanying drawings:

Upper slip 15 is provided with the boss with through hole; Main lower slip 14 two ends band tack axles 24, middle place band tip axle 29 and projection 28; Secondary lower slip 19 1 ends and middle place band tack axle 24, other end band tip axle 29.Place's through hole is enclosed within the boss that adds collar 25, upper slip 15 on the tip axle 29 of main lower slip 14 and is pasting main lower slip 14 and intersect to be stacked and form one group of slip group in the middle of the upper slip 15, and two groups of slips continuous is to be enclosed within on the tack axle 24 of main lower slip 14 and to be pressed into collar 25 by upper slip 15 through holes to form.Being added by some groups of slips that the slip group that is made up of crooked slip 13 links to each other with certain sequence consists of main expansion bracket 9.The boss of upper slip 15 is pasting secondary lower slip 19, boss through hole and is being nested with tack axle 24 and adds that collar 25 forms one group of slip, consists of secondary expansion bracket 10 by some groups of slips so that certain sequence is continuous.

Arrange at lower swivel becket 18 and to decide hook 21, moving hook 22 is placed on the gathering bar 6 of swivel becket 17 by connection shaft 16, loads onto Compress Spring 23, and it is fixed surely with anti-rotation that fixture block 20 will move hook 22.Six main expansion brackets 9 by connection shaft 16 with rotate up and down ring 17,18 and link to each other, six main expansion brackets 9 pass through crooked slip 13 and link to each other with six secondary expansion brackets 10.Hang extension springs 12 at two swivel beckets 17 that are stacked, 18 hangers 11.The cap cloth 2 quilts tip axle 29 of slip 14,19 down pierce through, and install on the telescoping mechanism, with packing ring 26 cap cloth 2 are pushed down, and will be placed on 27 and be press fit into 26 li on packing ring.

The telescoping mechanism that assembles is placed in down on the cap 3, and two swivel beckets 17,18 are enclosed within down on the cap 3 tegmental wall circles 4, and main expansion bracket 9 places on the support framework, and the main projection 28 of slip 14 down is placed on down 8 li of the guide grooves of cap 3.Upper cap 1 is more bigger than lower cap 3, upper cap 1 is tightly placed on the tegmental wall circle 4 of lower cap 3, and the cap assembling of whole son is complete.

When cap is in when stretch becoming big state, two swivel beckets 17,18 gathering bar 6 separately, extension spring 12 shortens; When with hand two gathering bars 6 being drawn close, two changes 17,18 relatively rotate, and telescoping mechanism shrinks, and extension spring 12 is elongated, and moves hook 22 and decides hook 21 phase hooks; Make it and decide hook 21 and throw off if press moving hook 22, cap will become big under the effect of extension spring.
