Drop-proof button

Abstract

The invention discloses a drop-proof button. The button comprises a clamping head part and a pressing part thereof; the clamping head part includes a front end and a rear end, a clamping mouth is formed in the front end of the clamping head part, the direction of an opening of the clamping mouth faces the pressing part, a bevel is arranged on the outer surface of the front end of the clamping headpart, and the bevel is tilted upward from the front end to the rear end direction. According to the drop-proof button, the outer surface of the front end of the clamping head part is arranged as thebevel, when one end of a strap is inserted into the clamping mouth, if a user pulls back the strap, the clamping head is driven to move toward the pressing part, so that the pressing part presses tightly the bevel of the outer surface at the front end of the clamping head part, and the clamping mouth clamps tightly the strap to prevent from dropping, if the strap receives again a larger external pulling force, because of the bevel effect, the pressing part slides along the bevel to further press the clamping mouth of the clamping head part, so that the clamping force exerted by the clamping mouth on the strap is greater, therefore, the greater the external pulling force of the strap, the greater the clamping force exerted by the clamping mouth on the strap, and the strap is effectively prevented from slipping out of the button; the drop-proof button is easy to use, and simple and reasonable in structure.

Description

technical field [0001] The invention relates to the technical field of buttons, in particular to an anti-off button. Background technique [0002] At present, buttons are applied to various fields, such as; belt buttons, schoolbag buttons, handbag buttons, etc., the working principle of traditional buttons: take a belt buckle as an example, one end of the belt is provided with a button, and the other end of the belt is inserted into the button mouth of the button, and the button There are movable latches, through which the user presses the strap to prevent the strap from coming out of the buckle. Yet the buckle of above-mentioned traditional structure still has the following deficiencies: (1) the anti-off of the belt, only the band is pressed by the movable bayonet, but because the end of the movable bayonet is sharp, it is easy to damage the belt, and the movable bayonet The compression strength of the teeth is limited, and when the belt is pulled by force, the belt is eas...

Problems solved by technology

Yet the buckle of above-mentioned traditional structure still has the following deficiencies: (1) the anti-off of the belt, only the band is pressed by the movable bayonet, but because the end of the movable bayonet is sharp, it is easy to damage the belt, and the movable bayonet The pressing strength of the teeth is limited. When the belt is pulled by force, the belt is easy to loosen because the clamping force is not further strengthened.
