Description

Adjusting buckle of belt

Technical Field

The present invention relates to a buckle, and more particularly to a buckle for a strap or the like, and more particularly to an adjustment buckle.

Background

In the prior art, the adjusting buckle of the belt has various structures, and the most common structure is a Chinese character ri buckle, a Chinese character mu buckle and the like. For example: CN208144597U discloses an adjustable fixing buckle with a shape of a Chinese character 'ri', which can firmly fix the passing binding band without loosening. However, the operation of the device requires two hands, which is inconvenient.

In daily life, adjustment buckles are used in many places, such as: adjusting the length of the backpack; safety belts for aircraft and car seats; binding bands for wrapping, and the like.

The disadvantages of these products are that they are difficult to adjust, slow, require two hands to operate, and are particularly significant when used on safety belts in the safety field.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide an adopt one hand just can operate the regulation knot, be applicable to occasions such as length adjustment and ligature.

The technical scheme of the utility model is that: an adjusting buckle of a belt, comprising the belt, and is characterized in that: the box body is also included, and a pin shaft is arranged on a base of the inner cavity of the box body; the pin shaft is provided with a pressure spring piece, and a button spring is arranged between the pin shaft and the pressure spring piece and used for increasing the downward pressure of the pressure spring piece; the belt enters through the inlet and then is clamped by the lower end of the pressure spring piece and then exits through the outlet; the upper end of the pressure spring piece is supported against the button.

the pressure spring plate and the bottom edge of the box body form an included angle alpha, and the included angle alpha is more than 30 and less than 60 degrees.

The belt buckle further comprises a belt flap for fixing one end of the belt.

The utility model discloses an in detaining the box, the pressure spring leaf forms with detaining the box base and is less than 60 degrees contained angles. Therefore, when the button is not pressed down, the belt is clamped by the acting force of the pressure reed, and the belt cannot be pulled out of the buckle box; when the button is pressed, the pressure spring is in a loose state, and the belt can be pulled out of the buckle box. Therefore, the utility model has the advantages that: the length of the back strap or the tightening and releasing of the binding belt can be adjusted by moving the strap by pressing the button of the buckle box with a single hand.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings and examples.

The utility model discloses an adjust and detain of belt, adjust and detain the belt cooperation that is used for having certain width usually, it includes belt 1 and detains box 2 two parts, and the concrete structure is seen as referring to fig. 1~ 2. The buckle box comprises a buckle box body 21, a pin shaft 22, a pressure spring piece 23, a torsion spring 24, a button 25 and a belt flap 26.

the buckling box body 21 is internally provided with a pin shaft 22, the pressure spring piece 23 is arranged on the pin shaft 22, a torsion spring 24 is arranged between the pin shaft 22 and the pressure spring piece 23, under the action of the torsion spring 24, the pressure spring piece 23 has a force rotating towards the bottom of the buckling box body 21, an included angle α is formed between the pressure spring piece 23 and the bottom of the buckling box body 21, the included angle α is more than 30 and less than 60 degrees, under the action of the torsion spring 24, the lower end of the pressure spring piece 23 is clamped with a belt, the belt is locked, and the upper end of the pressure spring piece 23 is propped against the button 3, which is described.

the included angle α between the pressure spring piece and the bottom of the buckle box body 21 is 35< α <45 degrees.

The belt climbs for securing one end of the belt.

In the using state, when the adjusting buckle 2 is held and the button 25 is pressed at the same time, the pressure spring piece 23 is loosened relative to the belt, and the adjusting buckle 2 is pulled to move on the belt 2.

Example 1:

the embodiment is characterized in that the adjusting buckle of the belt is used on the safety belt of the airplane seat, the structure of the safety belt is composed of the belt, an inserting buckle and the adjusting buckle, and the inserting buckle binds a person on the seat. Generally, the airplane seat belt is divided into two sections, the first section of belt is a fixed section, the length of the first section of belt cannot be adjusted, one end of the first section of belt is fixedly connected to the right side of the seat, and the other end of the first section of belt is connected with a buckle seat of an inserted buckle.

The second section is an adjusting belt, one end of the adjusting belt is fixedly connected to the left side of the aircraft seat, the other end of the adjusting belt is firstly installed behind the adjusting buckle (as shown in figure 2), then the adjusting belt penetrates through a climbing ring of a plug of the inserting buckle, and finally the adjusting belt is fixedly connected with a belt climbing at the tail part of the buckle box. When the safety belt is used, the safety belt is usually tightened by pulling the buckle box in the forward direction without pressing the button 25; when the safety belt needs to be loosened, the button is pressed down, and the buckle box 1 is reversely moved.

Example 2:

this embodiment uses a strap adjustment buckle on the backpack strap with one end of the strap attached to one end of the bag. The other end is firstly arranged behind the adjusting buckle (as shown in figure 2), then passes through the climbing ring at the other end of the backpack and is finally fixedly connected with the belt climbing 26 at the tail part of the buckle box.

When the straps of the backpack need to be adjusted, the button 25 does not need to be pressed normally, and the buckle box 1 can be tightened only by being pulled forward; when the safety belt needs to be loosened, the button 25 is pressed, and the buckle box 1 is reversely moved.

Example 2:

in this embodiment, an adjusting buckle of the strap is used on the binding strap, and the binding strap may be composed of two sections, namely a fixing section and an adjusting section. Or can be a section according to the actual requirement. The principle of the adjustment buckle is the same as the above-described embodiment.

When the binding device has binding function, the binding device can be used on a backpack, sports health equipment, medical equipment or a protective tool, and normal people only use one hand for operation, so that both hands can be liberated, and the tightness of the two belts can be easily controlled by one hand.

The utility model discloses to some special crowds, for example, the disabled person of a hand injury, can not both hands operate, under the condition that does not need someone else's help, just can operate alone.
