Abstract

The utility model relates to a fastener for belts or girdles, which is used for clamping and locking flexible tying belts, such as belts, suspenders, etc. The utility model is provided with a pair of S-shaped members which is made of hard material in a bending way and forms a right angle at the front side, and a middle rod C in the members is used for fixing the unmovable end of a tying belt. The rod body of the middle rod C is higher than a plane which is composed of a front rod A and a rear rod D of the members, and thus the side elevation of the members forms an inverted V shape. A clamping rod B is folded and extended along the upper return direction on the starting end of the front rod of the members, and a clamping gap between the clamping rod and the front rod of the members forms a clamping groove of the fastener for the belts or the girdles. When the utility model is used, the moving end of the tying belt penetrates through the upper part of the middle rod from the lower part of the rear rod of the members, and then the moving end of the tying belt is finally clamped in the clamping groove at the front end of the member. The product has the characteristics of simple and direct style, convenient operation, optional clamping and locking, etc.

Description

Bent other formula bracelet

The utility model belongs to the daily living article field, relates to a kind of bracelet that is used for flexible strap such as decorative waistband on kayser such as belt, parka and the skirt, company's bracing.

Known frenulum bracelet product branch has level to regulate and step-less adjustment two classes, there is level to regulate the mode that series products adopts alignment pin (button) with projection to insert the frenulum buttonhole and plays the fastening effect of locating, because the fastening degree of frenulum is that the snap-fastener eyelet is apart from adjusting, and the buttonhole gap is generally all between several centimetres, so that the user often is difficult to that frenulum is adjusted to neither loose not tight again optimum system and state, in addition, because this series products always only utilizes one or two buttonhole on the frenulum usually, the time one, the long frenulum that makes easily was from this buttonhole fracture; Commercially available step-less adjustment series products generally all is to come the clamping frenulum by the fixedly palate plate that has ratchet on hinge and its, this kind locate mode is often not exclusively reliable owing to the plastic deformation of frenulum material, shows that frenulum is through using becoming flexible of be moved after a period of time end or non-moving end.

The purpose of this utility model overcomes the defective of prior art, and then a kind of reasonable in design, long service life are provided, frenulum can be located at an arbitrary position the bent other formula bracelet of padlock chucking.

Design of the present utility model is such: adopt bent other formula kayser principle, the shape that is about to bracelet is made into class and does not fully turn over the square paper clip style of opening as one.This bracelet has a pair and is bent positive at right angles " S " type member that forms by hard material such as metal material or hard plastics etc., the middle part bar (C) of member is used for fixing the non-moving end of frenulum, this club shaft exceeds by bar before the member (A) and the plane that back bar (D) constitutes, and makes the side-looking face of member become " ∧ " type; The top of bar before member (A) along last time direction folding stretch out one with kelly (B), the draw-in groove of the folder crack formation bracelet before described kelly (B) and the member between the bar (A).In the use, the non-moving end cover of frenulum is twined on the king-rod that is fixed on " S " type member, make the bottom of mobile terminal bar behind " S " type member of frenulum penetrate and, not be stuck in the draw-in groove of member front end at last again through king-rod top.Because the lateral face of described member is the setting of " ∧ " type, frenulum is subjected to the force direction difference before, during and after member, thereby can guarantee the reliable and stable of bracelet kayser performance

Below with reference to accompanying drawing the utility model content is described further.

Fig. 1 is the perspective view of a specific embodiment of the utility model.

Fig. 2 is the forward face view of Fig. 1.

Fig. 3 is the side direction view of Fig. 1.

Fig. 4 is the fundamental diagram of structure shown in Figure 1.

With reference to accompanying drawing, described in the utility modelly get other formula bracelet and have a pair and bend positive at right angles " S " type member that forms by hard material, the middle part bar C of member is the frenulum fixed bar, non-moving end 1 cover with frenulum in the use twines also (with rivet or make) and is fixed on this bar, the middle part bar C body of rod will exceed by bar A before the member and the plane that back bar D constitutes, and makes the side-looking face of member become arch " ∧ " type; At the top of the preceding bar A of member along last time the direction folding stretch out one with kelly B, the folder crack between the preceding bar A of this kelly B and member promptly constitutes the draw-in groove of bracelet.When frenulum is carried out kayser, make the bottom of mobile terminal 2 bar D behind " S " type member of frenulum penetrate and, not be stuck in the draw-in groove that constitutes by A, B bar (Fig. 4) at last through king-rod C top.

Fig. 4 has provided illustrating of this embodiment design principle.Frenulum has four force positions on it behind kayser, i.e. A, B, C, and the D point, wherein the A point is that the strong point, B point are that fixing point, D point are symmetric points for bent other kayser point, C point.When B point and A, C distance between centers of tracks during less than 2 times of preparation frenulum thickness, bracelet two lateral frenum L ₁(near A point side) and L ₂(near D point side) promptly forms by straight line E at B point place ₁And E ₂Constitute less than 180 ° work angle, work as L ₁And L ₂When direction produces tension force to the left and right simultaneously, L ₁At the active force of E point place generation, in order to kayser L to B point direction ₂, the reflectivity that while A point is ordered to B plays a supportive role, owing to A, B, 3 stressed work of while of E, L ₂The work angle of ordering at B in last arbitrfary point is constant, makes the kayser of bracelet stable and reliable for performance.The symmetric points that the D point is ordered as B among Fig. 4 can be according to the symmetry of angle to guarantee that D point and B are ordered of preparation frenulum thickness adjustment ∠ BCD in the making.

Member described in the utility model can or be made plastic material firmly and make by metal material such as stainless steel, copper, aluminium, processing mode can adopt mechanical stamping, casting, casting and make mode by hand, and each size of product, angle, material specification are all selected voluntarily by the product technology requirement.

Compared with prior art, simple and direct generous, the operation freedom side of the style of the utility model product Just, its service behaviour is not subjected to the restriction of specified conditions, can arbitrarily position kayser to frenulum. This product also can according to different instructions for uses, be designed the product of multiple different style and class.
