A cord lock has a housing with an interior cavity and an opening extending between the front and the back for receiving a cord, and an actuator having two legs that are configured to slide within the interior cavity of the housing. A spring is disposed between the housing and the actuator to bias the actuator in a raised position relative to the housing. There is a cam disposed in the interior cavity of the housing. The bottom of the cam is rotatably connected to the housing and the top is rotatably connected to the legs of the actuator. In a resting position, the spring presses the top of the cam against the housing such that when a cord is extended through the opening, the cam locks the cord in place between the cam and the housing. Depressing the actuator compresses the spring and rotates the cam.

The present invention relates generally to first aid articles and more specifically tourniquets suitable for one handed application. One embodiment of the invention is directed to a tourniquet having a base defining first and second ends. A constricting band is attached to and extends from the first end of the base. A windlass handle is engaged with the constricting band. The constricting band is threaded through a self cinching stepped buckle. A buckle connector includes a hook member that engages the stepped buckle and is partly held in place through urging against a loop of the constriction band.

A press structure of a belt buckle includes a main body with a upper recess and main limit frame with a lower recess; the upper recess and lower recess are connected together to allow a plate control body with a pivoting shaft to be placed therebetween; the pivoting shaft is extended with a connecting part cooperating with a connecting shaft to connect a clamping element with the connecting part to form an adjustment area; and the clamping element is used to cooperate with an elastic element to clamp inside a groove of the main body, allowing the clamping element to have proper elastic force to press against the belt toward the inner side of the main limit frame to form a fixed state, so as to make the adjustment area pressable.

A belt buckle structure includes a buckle body and a plate-based controller. The buckle body is provided with a coupling section and a connection section at two ends thereof The coupling section is formed with a pivoting notch in a top side and a recess in a bottom side. A pin hole is formed in each of two sides of the buckle body. The plate-based controller includes a coupling axle having a pawl. The coupling axle is arranged in the coupling section. A fixing member has a protruding section fit into the recess. A pin is received through the pint hole to penetrate through the recess and extend into a positioning hole of the fixing member. A primary constraint frame has two side portions collaborating with the pin to attach to two sides of the buckle body.

According to one aspect of the present invention, a buckle for a clothing belt includes a first rotating body supported by the first shaft so as to be rotatable, an open end portion of the first rotating body being capable of being disposed between a bar and a back plate of a base body by making a first shaft slid; and a second rotating body supported by a second shaft so as to be rotatable with the second shaft as a fulcrum, formed so as to have a second convex portion, and capable of hindering a movement of the first rotating body in a direction opposite to the bar side with the second convex portion in a state where the second convex portion is rotated so as to be pushed in toward the opening portion of the back plate.

Provided is a device having an improved structure that lowers the unit cost and failure rate of a product by reducing the number of components and improves the assemblability, consistency in quality, operational stability, and convenience of future servicing of the product. In the device, a shaft and a shaft coupling part of a winding drum are simply coupled without a separate coupling member as a protruding portion formed on the shaft becomes caught in a catching portion formed on the shaft coupling part.
