CN2235740Y - Cam-type braces clip for trousers - Google Patents

Abstract

The utility model relates to a cam-type trousers belt clip used for tying trousers belts, which has various types. The utility model likes an oblong flat box with a through opening between two ends, one head of a face plate extends and is provided with a clip belt head, and a cam and a press plate are arranged in the clip belt head. The cam rotates, the diameter of the clip belt head is increased to impel the press plate to press the trousers belt on the box body, and the trousers belt is fixed by frictional force between the press plate and the trousers belt; the diameter of the clip belt head is reduced, and the press plate is reset by self elasticity to relax the trousers belt; the press plate has fewer pressure for the trousers belt, so the trousers belt has no press marks, and the trousers belt can keep self beautiful appearance and strength. Human body has no bulge press feeling on parts because a thin plate with the thickness less than one mm is arranged between the trousers belt and the human body. The utility model has the advantages of comfortable and convenient tying.

Description

Cam-type waist-belt card

The present invention is a kind of cam-type waist-belt card.Particularly be suitable for doing a waist-belt card of cortex waist-belt.

Existing waist-belt card all is to bore a hole on tape, pierce into the length that fixes frenulum in holes with the pin on the waist-belt card, fix laterally moving of band with a narrow basket, to look for prick post pin inconvenience with holes during frenulum, the intensity that has reduced band with holes and attractive in appearance, local narrow basket that protrudes and pin are to human body feeling of stress and uncomfortable.

The present invention on September 8th, 94 at the patent retrieval of Hubei Patent Office, no similar document.

It is convenient to the purpose of this invention is to provide a kind of frenulum, and human body does not have discomfort, retainer belt from glossy and intensity, the waist-belt card that prolongs the service time of band.

The object of the present invention is achieved like this, waist-belt card ectosome is flat the closing of rectangle two port, and the vertical prolongation of box body front plate is installed one and carried head secretly, clips of band, inner chamber is laterally installed a cam by front plate, and the axle at two of cam is contained in the side panel of box body.By a pressure zone plate cam and other half vertical port chamber are separated.The other end that the front plate clamping of pressure zone plate and box body is taken the lead joins together, and certain elasticity is arranged.When band (between pressing plate and box body back panel) from the waist-belt card passes when fastening trousers, pull down the outer bar of cam with hand, cam is rotated to big footpath by path pressing plate, pressing plate is pushed to band, band is pressed on the box body plate with pressing plate, so all there is a normal pressure on the both sides of band, pressure makes band and plate produce frictional force when vertical pulling band, when pulling force during less than frictional force band be fixed, cam forwards path to pressing plate to by big footpath during the pine band, pressing plate is by self elastic reset, and band i.e. pine.Inboard what paste human body is that an area is big and have only the thin plate human body of a few tenths of a mm not have the pressure sensitivity of ridge because box body is at band, because pressing plate is big with the contact area of band, pressure is little, there is not relative motion again, can not produce impression to band, guarantee band from glossy and intensity, need not look for holes during frenulum, degree of tightness can be adjusted arbitrarily, not having the sections sense, is to make things convenient for, if carrying head and box body secretly with being that monomer is with the hole cottered joint, when keeping frenulum length constant, dropout is carried head secretly and is come frenulum more convenient.

Box body of the present invention and pressing plate can be made with a sheet metal punching press or with the engineering plastics compacting.Cost is low.The box face can be pressed into various decorative patterns, mount decorations, elegant in appearance.

The present invention is described in further detail below with reference to accompanying drawing:

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the present invention.

Fig. 2 is the front elevation (band part section) of a kind of concrete structure of the present invention.

Fig. 3 is the transverse cross-sectional view of a kind of concrete structure of the present invention.

Fig. 4 is the longitudinal sectional drawing of the another kind of concrete structure of the present invention.

Fig. 5 is the front elevation (band part section) of the another kind of concrete structure of the present invention.

Fig. 6 is the transverse sectional view of the another kind of concrete structure of the present invention.

Know that by Fig. 1 this waist-belt card, profile are the flat boxes [1] of the vertical two of rectangle port, prolongation of box [1] front plate is made and is carried head [5] secretly, clip of band [6], a cam [2] laterally is installed in box [1], cam [2] two axle is supported in the axis hole of box [1] both sides side plate and with throw rod [7] and connects, and the pressing plate [3] that other end with box [1] front plate joins together separates cam [2] and vertical port chamber of wearing band [6].Pressing plate [3] has self elastic force, will be with [6] to pass from the box port when being waist-belt.Fasten the back the moving bar [7] of plate is pulled box [1] face, plate moves bar [7] and drives cam [2] rotation, pressing plate [3] forwards big footpath to by path relatively, pressing plate [3] is pushed to band [6], pressing plate [3] is pressed in band [6] on the back panel of box [1], when pressure hour can increase a supercharging backing plate [4] with pressurized energy between pressing plate [3] and cam.When drawstring [6], pressing plate [3], box [1] produce frictional force for the normal pressure of band [6], when pulling force during less than frictional force band [6] be fixed.When the moving bar of plate is pulled from the box face, cam [2] forwards path to pressing plate [3] to by big footpath, and pressing plate [3] is by self elastic reset, and band [6] is promptly loosening.

Know this waist-belt card by Fig. 4, pressing plate [3] also can be made into the same box of monomer [1] and make up installation.

Claims (5)

1. cam-type waist-belt card device, the flat box [1] that it is characterized in that rectangle two port of outer likeness in form, interior dress cam [2], pressing plate [3] and carry head [5] secretly and form, one of pressing plate [3] and box [1] are unified into one every between cam [2] and band [6], the axle of cam [3] is contained in the axis hole of box [1] biside plate, and links to each other with throw rod [7].

2. by the described waist-belt card device of claim 1, it is characterized in that pulling throw rod [7] cam [2] with hand rotates, relative pressing plate [3] forwards big footpath promotion pressing plate [3] to by path and is pressed on the band [6], forwards path pressing plate [3] to by self elastic reset by big footpath.

3. by claim 1,2 described waist-belt card devices, it is characterized in that between cam [2] and the band [6] that across pressing plate [3], cam [2] contact with band [6], pressing plate [3] and be with [6] no relative motion during pressure zone [6].

4. by claim 1,2 described waist-belt card devices, what it is characterized in that going up that spacing that pad pressuring plate [4] changes pressing plate [3] and box [1] base plate adapts to different-thickness band [6] at pressing plate [3] is work.
