Abstract

The utility model relates to an automatically retractable belt, which is formed by a strip-shaped leather belt (1) provided with a positioning hole (13) and a fastener device (2). The fastener device (2) comprises a casing (3), wherein a sliding block (4) capable of reciprocatingly sliding is arranged inside the casing (3), one end of the sliding block (4) is fixedly connected to the leather belt (1), and the other end of the sliding block is tied to the casing (3) via an extension spring (5). The automatically retractable leather belt is characterized in that a through hole (8) for the leather belt (1) to penetrate through is arranged above the sliding block (4) inside the casing (3), the upper edge of an opening of the hole extends forwards to from a ledge portion (9), and a round-headed pin (10) matched with the positioning hole (13) arranged on the leather belt (1) is disposed below the ledge portion (9) and extends downwards. Four walls of the through hole (8) have limit function on the leather belt (1) to ensure that the same is positioned on the root portion of the round-headed pin (10) all along without slippage, thereby evidently improving safety performance and reliability.

Description

The leather waistband of automatically retractable

Technical field

The utility model relates to a kind of waistband, is specifically related to a kind of extending or waistband of shortening.

Background technology

Waistband is commonly called as waist-belt, mainly is made up of leather belt and fastener (being commonly called as tap), by fastener with two snap fit of belt together, it is enclosed tie up to that the waist of trousers (or middle part of skirt) is gone up and the waist that trousers is fixed on human body during use.Because people's waistline changes, as the front and back of the meal of having enough and women's pregnancy period, so will be constantly carry out timely adjustment according to people's state under different states.Yet this adjusting then needs manually to carry out, and not only bothers, and also seems very unrefined in some public situation.At above-mentioned technical problem, the solution (notification number is CN 2312599Y) of office's on April 7 disclosed a kind of being entitled as in 1999 " waist-belt " is known by state.Above-mentioned patent scheme is made up of band, bracelet and zone circle; Wherein, described bracelet has a housing, be provided with a slide mass sliding back and forth in the housing, one of this slide mass is fixedly linked with described band, the other end is connected on the housing by spring system, when the variation of human body waist size, described spring just correspondingly elongates or shortens, thereby adjusts the tightness of waist-belt automatically.But, housing described in the above-mentioned patent scheme only provides the space that can hold described slide mass, therefore the other end of described band can only extend the other end of housing between bracelet and the human body, and then the clasp on the housing can be inserted with going up the interior realization of set locating hole bracelet be connected (referring to Fig. 1 of Figure of description) with band.This shows, obviously there is following deficiency in above-mentioned patent scheme: 1, clasp is only inserted in the set on tape locating hole and must just can be avoided clasp slippage from locating hole by zone circle, yet the effect of zone circle is also very limited, in case zone circle is far away slightly from bracelet, the deadweight of bracelet is easy to make clasp slippage and ineffective from locating hole; 2, since the head of band be pressed in below the fixing other end of bracelet, wear band and the operation fastened also very inconvenient, it is then more difficult to carry out the bigger adjusting of amplitude in the use especially; 3, the four sides cooperates between slide mass and the housing, very flexible, stuck phenomenon when slip occurring easily.

Summary of the invention

Improve the security reliability of waistband during the technical problems to be solved in the utility model with automatic Telescopic.

The scheme that the utility model solves the problems of the technologies described above is as follows:

A kind of waistband of automatically retractable, this waistband is made up of strip leather waistband and bayonet unit with locating hole, wherein, bayonet unit is by having a housing, be provided with a slide block sliding back and forth in the housing, one of this slide block is fixedly linked with described leather waistband, the other end is connected on the housing by extension spring system, it is characterized in that, the top that the body inherence of described housing is positioned at slide block is provided with the through hole that wears the leather waistband, the upper limb of this hole inlet extends an eaves portion forward, is provided with the cuphead pilotage that set locating hole is complementary on that extend and the leather waistband below this eaves portion downwards.

Another problem to be solved in the utility model is to dwindle the thickness of described housing and improve the flexibility that slide block reciprocatingly slides, and its solution is, the space that slide block is set in the body of set through hole that wears the leather waistband and housing in the body of described housing fuses; Be provided with guide frame between the corresponding inwall of the both sides of described slide block and housing, this structure can be made of movingly the arc convex of slide block both sides and the arc groove on the corresponding inwall of housing, also can be made of movingly the arc groove of slide block both sides and the arc convex on the corresponding inwall of housing.

In the above-mentioned improvement project and since described through hole with the slide block space be set fuse, described extension spring is exposed will certainly to wear by the described leather waistband of overslaugh if allow.In order to solve this technical problem, slide block of the present invention bottom is provided with a logical groove, described extension spring sets within it, two is connected with the termination of described groove and the inner end of housing respectively, and described slide block is close to the inner end of housing under the effect of described extension spring during nature.

In the above-mentioned basic scheme of the utility model, because the top in described housing body is provided with the through hole that wears the leather waistband specially, the cuphead pilotage that to locate usefulness simultaneously is arranged on the eaves portion that described through hole inlet upper limb extends forward, therefore under the restriction of described through hole wall, can guarantee described leather waistband be positioned at all the time cuphead pilotage root and can slippage, its security reliability is significantly improved.In addition, through hole described in the utility model is located at the top with a slide block of fixedlying connected of leather waistband, after coming one to pass through described through hole, must be positioned at the top of the other end that is connected with slide block, make wear band and the operation of fastening and common belt convenient equally.
