Description

helmet buckle

(一)技术领域(1) Technical field

本实用新型是有关于一种安全帽带扣，尤指一种操作较为方便顺畅且稳固的安全帽带扣，属于安全帽配件。The utility model relates to a safety helmet belt buckle, in particular to a safety helmet belt buckle with relatively convenient, smooth and stable operation, belonging to safety helmet accessories.

(二)背景技术(2) Background technology

现有的安全帽带扣如图1至图5所示，包括有一母扣1，一推钮2及一公扣3；其中，母扣1是由一铁片10及一外壳体16组成，铁片10底部具有一方孔11，方孔11前端突设有一凸块12。方孔11后方则具有一凸条13，凸条13上套设有一弹簧14，铁片10两侧各向上延伸且顶部内凹而形成具有一滑槽15；外壳体16是以塑胶成型包覆在铁片10之外，使母扣1前端形成一插入口，而外壳体16配合方孔11在顶端具有一缺口17。Existing safety helmet belt buckle is shown in Figure 1 to Figure 5, comprises a female buckle 1, a push button 2 and a male buckle 3; Wherein, female buckle 1 is made up of an iron sheet 10 and an outer casing 16, There is a square hole 11 at the bottom of the iron sheet 10, and a protrusion 12 protrudes from the front end of the square hole 11. There is a raised strip 13 behind the square hole 11, and a spring 14 is set on the raised strip 13. The two sides of the iron plate 10 extend upwards and the top is concave to form a chute 15; the outer shell 16 is covered by plastic molding. Outside the iron sheet 10 , an insertion opening is formed at the front end of the female buckle 1 , and the outer casing 16 has a notch 17 at the top end matching the square hole 11 .

推钮2，略呈L形，设于该母扣的滑槽15内，后端具有长槽供弹簧14套入，上端突出外壳体的缺口17，前端底部则被凸块12所抵挡限位。The push button 2 is slightly L-shaped and is set in the chute 15 of the female buckle. The rear end has a long groove for the spring 14 to be inserted into, the upper end protrudes from the gap 17 of the outer shell, and the bottom of the front end is resisted by the protrusion 12 to limit the position. .

公扣3，略呈凸形，前端具有一插掣片31，插掣片31中间具有一卡掣孔32，可与母扣的凸块12卡掣。The male buckle 3 is slightly convex, and has an inserting tab 31 at the front end, and a locking hole 32 in the middle of the inserting tab 31, which can be engaged with the protrusion 12 of the female buckle.

将公扣3插入母扣1时，是利用公扣插掣片31的前推力量将推钮2往前(内)推并压缩弹簧14，使插掣片31顺着滑槽15越过凸块12后，其卡掣孔32与凸块12卡掣，然后推钮2再利用弹簧14的恢复张力使推钮2回归原位，并将插掣片31抵住定位，以达卡扣的目的，如图2、图3所示；反之，当想要解扣时，是将推钮2往前推，使与插掣片31脱离，再将插掣片31自母扣1取出，而可将公扣3与母扣1解开，如图5所示。When the male buckle 3 is inserted into the female buckle 1, the push button 2 is pushed forward (inwardly) by the forward force of the male buckle insertion piece 31 and the spring 14 is compressed, so that the insertion piece 31 goes over the protrusion along the chute 15 After 12, the locking hole 32 is locked with the protrusion 12, and then the push button 2 returns to the original position by using the recovery tension of the spring 14, and the insertion piece 31 is held against the position, so as to achieve the purpose of buckling , as shown in Figure 2 and Figure 3; on the contrary, when you want to release the buckle, push the push button 2 forward to disengage from the latch 31, and then take the latch 31 out of the female buckle 1, and you can Untie the male buckle 3 and the female buckle 1, as shown in Figure 5.

上述现有的安全帽带扣，在卡扣时是利用插掣片的卡掣孔32与凸块12二者卡掣结合所达成，然因卡掣孔32是设于插掣片31中间位置处，且与凸块12之间存有相当的间隙，而凸块12则是呈突设在铁片10的前端，致使公扣3与母扣1卡扣时，形成点的卡掣状态，导致公扣3会产生幌动、松弛的状态，而令人有容易松脱的不安全感；又，在解扣时，再将推钮2前推使与插掣片31脱离后，公扣3并无法自动脱出母扣1，而仍须人手将插掣片31自母扣1取出，方能完成解开公扣3与母扣1的目的，在操作上显然较为麻烦不便。The above-mentioned existing safety helmet belt buckle is achieved by using the locking hole 32 of the insertion piece and the protrusion 12 to engage when buckling. However, the locking hole 32 is located in the middle of the insertion piece 31. , and there is a considerable gap between the protrusion 12, and the protrusion 12 is protrudingly arranged on the front end of the iron sheet 10, so that when the male buckle 3 and the female buckle 1 are buckled, a dotted locking state is formed, As a result, the male buckle 3 will be in a swaying and slack state, which makes people feel insecure that it is easy to loosen; 3 and can't get out of the female buckle 1 automatically, but still have to manually take out the inserting piece 31 from the female buckle 1 to complete the purpose of untying the male buckle 3 and the female buckle 1, which is obviously troublesome and inconvenient in operation.

(三)发明内容(3) Contents of the invention

本实用新型的主要目的在于提供一种操作较为方便顺畅且稳固不易松脱的安全帽带扣。The main purpose of the utility model is to provide a safety helmet belt buckle which is relatively convenient and smooth to operate, stable and not easy to loosen.

本实用新型一种安全帽带扣，其包含：一母扣，由一铁片及一包覆在该铁片外的外壳体所组成，其底部具有一卡掣槽，两侧具有一滑槽，滑槽外侧各套设有一弹簧；一推钮，设于该母扣的滑槽内，其后端与母扣之间抵接有一弹簧；及一公扣，前端具一插掣片，插掣片前端底部并下突设有一卡掣块，使与母扣的卡掣槽卡扣，该插掣片后端两侧均具有一肩部，使与母扣两侧的弹簧接触，以达到操作方便顺畅且稳固的目的。The utility model is a safety helmet belt buckle, which comprises: a female buckle, which is composed of an iron sheet and an outer shell covering the iron sheet, with a catch groove at the bottom and a slide groove at both sides , a spring is set on the outer side of the chute; a push button is set in the chute of the female button, and a spring is contacted between the rear end and the female button; There is a catch block on the bottom of the front end of the catch and protruding downwards, so that it can be buckled with the catch groove of the female buckle. The operation is convenient, smooth and stable.

本实用新型一种安全帽带扣，其优点和功效在于：The utility model is a safety helmet buckle, and its advantages and effects are:

1.卡掣槽41是呈矩形且直接设于铁片40中间底面的位置处，而卡掣块62则下突于插掣片61底部，因此一旦卡掣块62卡入卡掣槽41内时，不但插掣片61已深入母扣4一段距离，并且卡掣块62与卡掣槽41也形成面的卡掣状态，因此不但较无间隙而不致幌动松弛，并且也较为稳固不易松脱。1. The locking groove 41 is rectangular and is directly located at the middle bottom of the iron plate 40, while the locking piece 62 protrudes downward from the bottom of the insertion piece 61, so once the locking piece 62 is stuck into the locking groove 41 At this time, not only the insertion piece 61 has penetrated into the female buckle 4 for a certain distance, but also the locking block 62 and the locking groove 41 also form a surface locking state, so not only there is no gap and no looseness, but also it is relatively stable and not easy to loosen. take off.

2.在卡扣时，由于插掣片61后端顶部是具有一呈圆形凸体的导块64，故一旦卡掣片61插入母扣4内时，即可利用该导块64的引导而可迅速且顺利地使公扣6与母扣4卡掣扣合，在操作上显然相当方便顺畅。2. When buckling, since the top of the rear end of the insertion piece 61 has a guide block 64 in the shape of a circular convex body, once the locking piece 61 is inserted into the female buckle 4, the guide block 64 can be used to guide However, the male buckle 6 and the female buckle 4 can be snapped together quickly and smoothly, which is obviously quite convenient and smooth in operation.

3.在解扣时，只要轻轻一推推钮5，即可令公扣6自动弹出与母扣4脱离，在操作上显然相当方便顺畅。3. When unlocking, just push the push button 5 lightly, the male buckle 6 will automatically pop up and separate from the female buckle 4, which is obviously quite convenient and smooth in operation.
