Safety helmet buckle structure

The present invention relates to a safety helmet buckle structure, in particular to a length that can be freely adjusted in a stepless manner when the buckle is fastened, and the tightness, and the impact is not easily loosened or dropped, or is driven at a high speed. At the same time, the buckle of the helmet is not affected by the wind resistance.

The buckle structure of the early helmet is mainly used by a male buckle and a female buckle. Because the male and female buckles are made of plastic material, although they are light in weight and low in cost, they are Plastic material, so its fastening tightness is poor, it is easy to break and loose when it is impacted, and it is easy to cause wear and damage after long-term use.

Therefore, there is a new type of "Machine Snap Ring" patent case No. M376176 announced by the Republic of China on March 21, 1999. It is disclosed: it includes a male buckle ring and a female buckle ring, wherein the male buckle ring is at one end of its elastic buckle piece. a metal piece integrally pressed with the same; the female buckle ring is provided with a metal piece integrated with the upper end of the open end of the insertion hole; when the male buckle ring is combined with one end of the elastic buckle piece, the female end is inserted into the female When the socket of the buckle is inserted, the elastic buckle of the male buckle ring is engaged with the upper edge of the open end of the female buckle ring jack, so that the metal piece of the elastic buckle of the male buckle ring and the metal piece of the female buckle ring are provided. Contact, thereby achieving the goal of light weight, low cost, easy to pass test standards and not easy to wear and tear.

However, the method of unlocking the patent is mainly to separate the male and female buckles by pressing the male buckle, but the tripping method has more impact points, and the impact is automatically caused by a slight impact. Unfasten, so that the helmet is separated from the user's head, so that it loses protection, or it is driven at a high speed. When the wind resistance is too large, it is easy to cause the helmet to be skewed or fall off, so there is a hidden danger in use.

There is also a new patent No. M243966 "Light-force push-type buckle structure" announced by the Republic of China on September 21, 1993. It is disclosed by a female fastener, a male fastener and an elastic block; The female fastener has a ring hole at one end, a slot at the other end, a diagonal card block in the slot, a frame port on the slot to embed the card block, and one end of the male fastener member is provided with a ring hole at the other end. Inserting piece, setting bit slot on the inserting piece, pressing plate at the top of the elastic card block, and a ring-shaped buckle ring at the bottom end, the inclined ring is arranged in the buckle ring, and an extended elastic piece is arranged on the buckle ring, the card is arranged There are buckles on both sides of the block, which can be buckled on the card steps of the side of the frame of the female fastener to prevent the out of the frame. The elastic card block can be embedded in the frame of the female fastener, and the elastic piece can be The top is abutted on the card block in the slot; the card block is placed in the frame mouth, and when the male fastener is inserted into the female fastener, the positioning groove and the diagonal block can be engaged.

However, the patent is similarly released by the pressing method. Therefore, there are also many impact points, easy to automatically disengage and separate, and it is easy to be affected by windage at high speed to cause skew or fall off, so it is rather unsatisfactory in use.

Therefore, in view of the above-mentioned safety helmet buckles, which have the above-mentioned various kinds of defects, the present invention provides a safety helmet buckle structure, which is provided with a housing, which is provided with an inlet and an outlet, and the inside of the housing A chamber is provided, the chamber is connected to the inlet and the outlet, and the chamber is provided with a pressing portion between the inlet and the outlet, and a position is provided at a position relative to the pressing portion. a retaining block, wherein the housing is provided with a fixing portion, and a sliding slot is disposed on two sides of the housing, and the housing is provided with a slot; a pressing unit is disposed on the housing Indoor, the pressing unit is provided with at least one roller, the roller is abutted between the inlet and the outlet, the peripheral ring of the roller is provided with a plurality of pressing blocks, and the roller is provided with a shaft, the shaft The two ends of the rod are respectively disposed in the two chutes, and the shafts are respectively A pull rod is fastened, and one end of the pull rod is provided with a pull handle, and the pull handle protrudes outside the slot, and the pull rod pushes the pressing block of the roller to press the pressing portion to generate a pressing force. And pressing the stopper; a buckle, which is penetrated by the inlet of the housing, passes through the outlet, and is pressed and positioned by the pressing force of the pressing block.

The shell base is formed by a first half of the first housing and a second shell.

The combination of the first housing and the second housing is a high-frequency bonding manner, a fusion bonding manner, a fitting manner, or a screwing manner.

The inlet is disposed at a front edge of the first casing, and the outlet and the fixing pillar are disposed at a top edge of the first casing.

The chambers are formed together in the first housing and the second housing, so that the interiors of the first housing and the second housing respectively form a half of the chamber.

The pressing portion is disposed on the first housing, and the stopper is oppositely disposed on the second housing.

The fixing portion is disposed at a rear edge of the second casing.

The chute is recessed on the inner side of the first casing.

The slot is disposed above the rear edge of the first housing, and the two sides of the slot are respectively provided with a blocking piece.

The buckle is provided with at least one fixing hole, and the first housing is provided with a fixing post, and the fixing post is fastened in the fixing hole.

The pressing portion is formed in a class shape.

The pull rod is fastened to the elastic rod, and the elastic element is located in the chamber, and The elastic top is abutted against the wall surface of the chamber and between the tie rods to push the pressing block of the roller to generate the pressing force.

This creation has the following advantages:

1. The creation system can freely pull the buckle belt without a segment to adjust the length of the buckle when the buckle is fastened and the tightness thereof, so that the helmet can be fastened and fastened without being loosened.

2. The buckle structure of the present invention mainly uses the pulling method of pulling a handle, and can loosen the tightening action of the buckle, so that no impact point exists, even if it is subjected to strong force from different directions. When the impact occurs, the flaps on the two sides of the slot can also be used to block the handle, and the buckle can be used to cover the handle, so as to prevent the handle from being easily loosened when it is hit, so It can ensure the safety of the user.

3. This creation, especially at high speeds, is not affected by the wind resistance, and the helmet is slanted or loosened at will, so that the safety of the helmet can be further ensured.

4. The sliding slot of the present invention is recessed on the inner side of the first housing, so that the two ends of the shaft of the roller can only move in the limit of the two sliding slots, and are not exposed outside the housing. Therefore, no impact point will be generated, and it will not be automatically released when it is hit, and danger will occur to ensure the safety of the driver.
