Description

拉链 技术领域
本实用新型涉及拉链技术领域，特别涉及一种具有锁扣功能的拉链。
背景技术
拉链是把两片织物暂时结合在一起的一种部件，常见于衣物、旅行箱、手袋、帐篷和睡袋等，拉链一般由链牙、拉头、上下止等组成，其中链牙是关键部分，它直接决定拉链的侧拉强度。一般拉链有两片链带，每片链带上各自有一列链牙，两列链牙相互交错排列。拉头夹持两侧链牙，借助拉襻滑行，即可使两侧的链牙相互啮合或脱开。
现有的拉链，通常背包在背负时若不注意，背包上的拉链容易自行打开，导致包内的物品掉落丢失，带来不必要的麻烦，且背包背负在身后，不注意时容易被人打开，导致背包内的物品被偷盗的问题。因此，如何解决上述问题是本领域技术人员的研究方向之一。
实用新型内容
有鉴于此，本实用新型提出一种具有锁扣功能的拉链。
本实用新型提供一种拉链，包括拉链带、连接在拉链带上的第一拉头和第二拉头以及分别连接在所述第一拉头和第二拉头上的第一拉片和第二拉片，所述第一拉片上设有第一卡扣部，所述第二拉 片上设有第二卡扣部，当所述第一拉头与所述第二拉头拉合在一起时，所述第一卡扣部与所述第二卡扣部配合使得所述第一拉片与所述第二拉片卡扣连接。

在一实施例中，所述第一配合面靠近所述第一拉头的一端向外突出形成第一加厚部，所述第二配合面靠近所述第二拉头的一端向外突出形成第二加厚部，当所述第一拉片与所述第二拉片卡扣连接时所述第一加厚部与所述第二加厚部相互错开。
在一实施例中，所述第一配合面上环绕所述卡扣柱设有第一环形件，所述第二配合面上环绕所述卡扣孔设有第二环形件。
在一实施例中，所述第一配合面上设有第一凹槽，所述第二配合面上设有第二凹槽，所述第一环形件设置在所述第一凹槽内，使得所述第一环形件的外侧面与所述第一配合面平齐，所述第二环形件设置在所述第二凹槽内，使得所述第二环形件的外侧面与所述第二配合面平齐。
在一实施例中，所述第一卡扣部为卡扣柱，所述第二卡扣部为卡扣槽。
在一实施例中，所述第一拉片具有第一配合面，所述卡扣柱自所述第一配合面凸出延伸形成，所述第二拉片具有第二配合面，所述卡扣槽设置在所述第二配合面上。
综上所述，本实用新型提供一种具有锁扣功能的拉链，在第一拉片上设置第一卡扣部，在第二拉片上设置第二卡扣部，当第一拉头与第二拉头拉合在一起时第一卡扣部与第二卡扣部卡扣连接，进而使得第一拉片与第二拉片卡扣连接。第一卡扣部可以设置为卡扣柱，第二卡扣部设置为与卡扣柱配合的卡扣孔，卡扣柱卡扣入卡扣孔内实现拉链的锁扣，避免在使用过程中拉链自行打开，起到防盗的作用。本实用新型的拉链结构简单，外形美观，操作方便，实用性强，给用户带来方便。

具体实施方式
在详细描述实施例之前，应该理解的是，本实用新型不限于本申请中下文或附图中所描述的详细结构或元件排布。本实用新型可为其它方式实现的实施例。而且，应当理解，本文所使用的措辞及术语仅仅用作描述用途，不应作限定性解释。本文所使用的“包括”、“包含”、“具有”等类似措辞意为包含其后所列出之事项、其等同物及其它附加事项。特别是，当描述“一个某元件”时，本实用新型并不限定该元件的数量为一个，也可以包括多个。
如图1-2所示，本实用新型提供一种具有锁扣功能的拉链10，该拉链10可用于背包、旅行箱、旅行包、手袋等物品上，以防止这些物品在使用过程中发生自行打开的情况，而导致装在这些物品内的私人用品掉落丢失甚至被偷盗。本实施例中以背包为例对本实用新型进行说明。
拉链10包括拉链带12、第一拉头14、第二拉头16、第一拉片18和第二拉片20。拉链带12上设有拉链链牙22，第一拉头14和第二拉头16可滑动地连接在拉链链牙22上。第一拉片18和第二拉片20分别通过拉环24活动连接至第一拉头14和第二拉头16，例如，在第一拉头14、第二拉头16、第一拉片18和第二拉片20上分别设置穿孔，利用一拉环24同时套设第一拉头14和第一拉片18的穿孔，利用另一拉环24同时套设第二拉头16和第二拉片20的穿孔。第一拉片18和第二拉片20用于供用户拉动，从而分别带动第一拉头14和第二拉头16在拉链链牙22上滑动，实现拉链带12的开合。
第一拉片18上设有第一卡扣部26，第二拉片20上设有第二卡扣部28，当第一拉头14与第二拉头16拉合在一起时，第一卡扣部26可与第二卡扣部28卡扣配合以使得第一拉片18与第二拉片20卡扣连接，防止在使用过程中第一拉头14与第二拉头16自行打开，起到防盗的作用。
请同时参考图3和图4，本实施例中，第一卡扣部26实施为卡扣柱26，第二卡扣部28实施为用以与卡扣柱26卡扣配合的卡扣孔28。更具体地，第一拉片18和第二拉片20均为中部微微拱起的圆滑的板片状结构。第一拉片18具有第一配合面30，第一配合面30上靠近第一拉头14的一端向外突出形成第一加厚部32；第二拉片20具有第二配合面34，第二配合面34上靠近第二拉头16的一端向 外突出形成第二加厚部36。第一加厚部32和第二加厚部36的设计可方便用户手拉拉动第一拉片18和第二拉片20，使得施力更为容易。
第一配合面30上远离第一拉头14的一端向外凸出延伸形成卡扣柱26，卡扣孔28贯穿第二拉片20设置，且卡扣孔28的位置对应卡扣柱26设置。当第一拉片18与第二拉片20卡扣连接时，卡扣柱26从第二配合面34卡扣入卡扣孔28内，同时，第一加厚部32与第二加厚部36之间相互错开，以避免影响卡扣动作。也就是说，第一拉片18与第二拉片20卡扣连接时二者需要错位，避免第一加厚部32与第二加厚部36之间发生抵触。
在所示的实施例中，第一配合面30上环绕卡扣柱26设有第一环形件38，第二配合面34上环绕卡扣孔28设有第二环形件40。设置第一环形件38和第二环形件40可避免卡扣柱26在卡扣入卡扣孔28内时卡扣柱26与第二配合面34之间发生接触摩擦对第二拉片20造成划伤，或者第一拉片18与第二拉片20卡扣连接后第一配合面30与第二配合面34接触，二者之间可能会发生微小的相对转动而相互摩擦造成损伤，同时可增加第一拉片18和第二拉片20的美观度。而且，第一环形件38和第二环形件40可采用高亮反光材质，在夜间或光线不足的环境下也可很容易地找到拉片并进行卡扣动作，给用户带来方便。
更具体地，在第一配合面30上环绕卡扣柱26设置一第一凹槽42，在第二配合面34上环绕卡扣孔28设置一第二凹槽44，第一环形件38容置在第一凹槽42内，第二环形件40容置在第二凹槽44内，并使得第一环形件38的外侧面与第一配合面30平齐，第二环形件40的外侧面与第二配合面34平齐。
在上述实施例中，第一卡扣部26实施为卡扣柱26，第二卡扣部28实施为用以与卡扣柱26卡扣配合的卡扣孔28。在一些实施例中，也可以是第一卡扣部26实施为卡扣柱，第二卡扣部28实施为用以与卡扣柱26卡扣配合的卡扣槽。在其他实施例中，第一卡扣部26与第二卡扣部28之间也可以其他方式实现卡扣配合。
综上所述，本实用新型提供一种具有锁扣功能的拉链，在第一拉片上设置第一卡扣部，在第二拉片上设置第二卡扣部，当第一拉头与第二拉头拉合在一起时第一卡扣部与第二卡扣部卡扣连接，进而使得第一拉片与第二拉片卡扣连接。第一卡扣部可以设置为卡扣柱，第二卡扣部设置为与卡扣柱配合的卡扣孔，卡扣柱卡扣入卡扣孔内实现拉链的锁扣，避免在使用过程中拉链自行打开，起到防盗的作用。本实用新型的拉链结构简单，外形美观，操作方便，实用性强，给用户带来方便。
本文所描述的概念在不偏离其精神和特性的情况下可以实施成其它形式。所公开的具体实施例应被视为例示性而不是限制性的。因此，本实用新型的范围是由所附的权利要求，而不是根据之前的这些描述进行确定。在权利要求的字面意义及等同范围内的任何改变都应属于这些权利要求的范围。
