Description

Helmet buckle

The invention relates to a safety helmet buckle, in particular to a structure with simple structure, simplified manufacturing and light weight.

The applicant has previously improved the patent TWM376183 and obtained the new patent TWM503787. The structure of the conventional example is shown in Figures 1 and 2, including: a male buckle 1, made of metal material, with an insert 11 at the front, and There is a lug 12 protruding on both sides of the end. The insert 11 has a plurality of button holes 111. The button holes 111 can be arranged in two groups. The two lugs 12 can be pivotally connected to a belt. The body joint 13 includes a fan-shaped fixing block 14 and a U-shaped buckle 15 to be pivotally fixed to the lug 12 by a shaft 16 and can be fixed by the fixing block 14 and the buckle. A belt is inserted in the gap between 15; and A female buckle 2 is composed of a base 21, a button 22, a buckle 23, and two torsion springs 24; wherein the base 21 is U-shaped, and the rear end has a belt joint 211 for passing through Set another strap; the fastener 23 is set under the button 22, and at the same time by a pivot 221 and the base 21 pivotally, so that there is a cavity 212 between the button 22 and the base 21 for The insert 11 is inserted; the base 21 and the inner side of the front end of the button 22 are provided with a corresponding stop 213 and a recess 222 respectively. The rear end of the button 22 has a flap 223; the button There are two detent teeth 231 and an abutment block 232 below the rear end respectively. The detent teeth 231 can be engaged with the insert button hole 111; the two torsion springs 24 are respectively arranged in the cavity 212 of the base At the two ends, one end is wound on the pivot 221, and the other end is hooked on the base 21, so that the fastener latching teeth 231 are constantly pressed down by its elastic force.

Although the above-mentioned conventional safety helmet buckle can achieve the effects of good fastening stability and simple structure, in fact, it still has the following shortcomings to be improved.

1. The structure is still too complicated. The male buckle 1 is composed of an insert 11 and a belt joint 13, while the belt joint 13 is composed of a fixing block 14, a U-shaped buckle 15 and a shaft 16, and the structure is obviously complicated .

2. The male buckle includes insert 11, fixed block 14, U-shaped buckle 15 and shaft 16 and many other components. Not only is it more complicated to manufacture, but it also needs to be assembled one by one, which is time-consuming, that is, its manufacturing It is more complicated and troublesome, which increases costs.

3. Due to its complex structure, the male buckle 1 weighs 18.8 grams, which is obviously not light enough to use.

The main purpose of the present invention is to provide a helmet buckle with simple structure and simplified manufacturing, which can reduce the cost.

Another main purpose of the present invention is to provide a lightweight safety helmet buckle, which is easy to use.

To achieve the above object, the present invention includes: a male buckle, made of metal, with an insert at the front end, and a belt engaging unit at the rear end. The insert has a plurality of button holes, and the belt engaging unit is equipped with A slot with an upper protruding buckle in the middle of the slot for passing the belt body; and a female buckle consisting of a base, a button, a buckle and two torsion springs, the buckle is attached to The bottom of the button is pivotally connected to the base by a pivot, so that there is a cavity between the base and the button for insertion of the insert. The fastener has a latching tooth, which can be used by the torsion spring The elastic force keeps the latch tooth in a state of being continuously pressed down, and can be clamped with the buckle hole of the insert piece; thereby, the effect of simple structure and simplified manufacturing is achieved.

In the above-mentioned safety helmet buckle, the insert piece of the male buckle and the belt body joint unit are integrally formed, so as to reduce the assembly procedure.

In the above-mentioned safety helmet buckle, the groove of the belt body engaging unit is preferably rectangular.

In the above-mentioned safety helmet buckle, each of the left and right sides under the front end of the female buckle base has a protruding piece, and a rail groove is provided between the protruding piece and the cavity to facilitate insertion of the insert.

The following is a preferred and feasible embodiment with accompanying drawings to detail the structural features and effects of the present invention as follows, so as to make it easy to understand and agree with.

Please refer to FIGS. 3-6 at the same time. The present invention includes a male buckle 3 and a female buckle 4, wherein the male buckle 3 is integrally formed from a metal material, and has an insert 31 at the front end and a belt body joint at the back end. The unit 32 has a plurality of button holes 311 on the insert 31, and the button holes 311 can be arranged in a group of two. The belt engaging unit 32 has a slot 321, and the slot 321 is Rectangle is better, and there is an upper protruding buckle 322 in the middle for passing a belt body; The female buckle 4 is roughly the same as the conventional one, and is composed of a base 41, a button 42, a buckle 43, and two torsion springs 44. The rear end of the base 41 has a belt joint 411, In order to pass through another belt body, the base 41 has a protruding piece 414 on the left and right sides under the front end (under the stop block 413), so that a rail groove is formed between the protruding piece 414 and the bottom surface of the cavity 412. For the insert 31 to be inserted.

According to the above-mentioned structural combination, insert the insert 31 of the male buckle into the cavity 412 of the female buckle base when in use, as shown in Fig. 3, while entering along the rail groove and following the inclined surface of the rear end of the latch tooth 431 , Slightly push the latch teeth 431 upwards, so that the button 42 and the fastener 43 move up synchronously, and then immediately use the elastic force of the torsion spring 44 to make the fastener latch teeth 431 snap into the insert button hole 311 , Make the male buckle 3 buckle in the proper position in the female buckle 4, as shown in Figures 5 and 6, to achieve the purpose of fastening. On the contrary, as long as the trigger 423 of the trigger button is pulled up, the latching tooth 431 is separated from the buckle hole 311, and the male buckle 3 can be taken out, as shown in FIG. 7.

From the above description, it can be seen that the present invention has at least the following advantages and effects, which is far more advanced than the conventional ones.

1. The structure is relatively simple. The belt engaging unit 32 of the male buckle only has the notch 321 and the buckle 322, and the belt engaging unit 32 and the insert 31 are integrally formed, which is naturally simple in structure.

2. Simplified manufacturing. The belt body joint unit 32 and the insert 31 of the male buckle are integrally formed without other components. The assembly procedure can be automatically reduced. The structure is simple and the manufacturing is simplified, which naturally reduces the cost.

3. Lightweight, the weight of the male button is only 11.4 grams, which is 7.4 grams less than the conventional one. It is obviously lighter in use.

4. In the belt body joining unit 32 of the male buckle, the buckle piece 322 in the middle of the notch 321 is in a protruding state, so the distance between the buckle piece 322 and the notch 321 can be increased, which is beneficial to the belt body Piercing joints.

In summary, the specific structure disclosed in the embodiment of the present invention is confirmed to be different from conventional knowledge, and can achieve the expected purpose and function. It can be called a novel and advanced invention. A patent application for invention is filed according to law.
