Abstract

The utility model relates to a cap with a changeable shape, which can extend and shrink. A telescopic mechanism is arranged between an upper cap and a lower cap; a piece of cap cloth is arranged on a main telescopic rack and an auxiliary telescopic rack of the telescopic mechanism; the cap cloth can extend and shrink according to the telescopic mechanism. One end of the main telescopic rack is connected with a steel wire ring through a connection block, and a bent sheet strip arranged on the other end of the telescopic rack is connected with the auxiliary telescopic rack, thus the telescopic mechanism of the cap is formed by the parts. The telescopic mechanism is arranged between the two caps through a supporting block, a cover plate and screws.

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 back 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 fully satisfy the needs of people's sun-shading rain-proof.

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

The utility model is achieved in that

The steel wire ring links to each other with main expansion bracket, and main expansion bracket links to each other with secondary expansion bracket, constitutes telescoping mechanism; Cap cloth is placed on the telescoping mechanism, and telescoping mechanism is placed between cap and the following cap.

On the main expansion bracket bool is housed, the bool of main expansion bracket is linked to each other with secondary expansion bracket by connecting piece.

Two rotors are placed between two caps, and two caps link to each other with connecting piece, and two rotors link to each other with main expansion bracket.

Fixedly connected forms two rotors on the two steel wire rings, and they are placed

Fixedly connected forms two rotors on the two steel wire rings, and they are placed in the groove of the rest pad between two caps; Connecting block on the steel wire ring links to each other with main expansion bracket by hollow shaft.

Between last cap and following cap, telescoping mechanism is installed, thus stretching out of the major and minor expansion bracket by telescoping mechanism and magnifying and dwindling of the control cap of withdrawing.Main expansion bracket can only be regained a part of cap cloth, and remaining is regained by secondary expansion bracket.

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

Fig. 1 stretches the view that becomes big for Changeable size cap.

Fig. 2 shrinks the view that diminishes for Changeable size cap.

Fig. 3 is the cutaway view of Fig. 2.

Fig. 4 is main expansion bracket view.

Fig. 5 is secondary expansion bracket view.

Fig. 6 is that the A of Fig. 1 is to view.

Described in detail in conjunction with the accompanying drawings:

Boring couples together slip 17 with step axle 14, fibula 15, hollow shaft 16 on slip 17, is assembled into main expansion bracket 2 and secondary expansion bracket 4.Slip 17 on the main expansion bracket 2 links to each other with secondary expansion bracket 4 by hollow shaft 16, constitutes the major part of telescoping mechanism.

Last connecting block 5 and the special connecting block 29 of going up are fastened on the steel wire ring 11, connecting block 6 and special connecting block 30 down are fastened on down on the steel wire ring 12 down.With screw 3 and cover plate 13 steel wire ring 11,12 is covered in rest pad 9 grooves.

The slip 17 of main expansion bracket 2 links to each other with connecting block 5,6 by hollow shaft 16 respectively; On last connecting block 5 and following connecting block 6, hang extension spring 18.

The binding of above-mentioned parts, assembling has constituted the telescoping mechanism of Changeable size cap.Cap cloth 1 links to each other with major and minor expansion bracket 2,4 by fibula 15.

When main two connecting blocks 5,6 of stretching on the frame 2 were drawn close mutually, two steel wire rings 11,12 relatively rotated, and telescoping mechanism stretches and enlarges; Otherwise, then dwindle withdrawal.

Following cap 7 is provided with the guide groove 27 that makes the normal operation of telescoping mechanism energy and has the bar hole 28 that allows special connecting block 29,30 pass.With screw 10 cap 7 down, go up cap 8 and couple together with telescoping mechanism, step axle 22 couples together moving hook 23 and special upward connecting block 29; Load onto compression spring 19, curve the little fixture block of special connecting block 29 again, make spring have restoring force.

Stay hook 24 is fixed on the special connecting block 30 down by rivet 25.

When needs open cap, press by bar 21 and make hook 23 and stay hook 24 disengagements, under the pulling force effect of extension spring 18, telescoping mechanism stretches and opens, and extension spring 18 just shortens.

Draw special connecting block 29,30 in hand and make hook 23 and stay hook 24 hook mutually, telescoping mechanism shrinks, and extension spring 18 is elongated, and prepares for opening next time.

Claims
