Description
本申请要求于下列中国专利申请的优先权,其全部内容通过引用结合在本申请中:
1、2018年7月13日提交中国专利局、申请号为201810769575.8、名称为“一种拉链头及拉链”的中国专利申请;
2、2018年7月13日提交中国专利局、申请号为201821115675.0、名称为“一种拉链头及拉链”的中国专利申请。
本发明涉及拉链技术领域,更具体地说,涉及一种拉链头及拉链。
拉链是日常生活中较为常见的产品,其主要应用于服装、箱包、帐篷等行业,拉链在使用时,安装在其布带上的拉头起到十分重要的作用,通过拉动拉头,可以实现对拉链开合状态的转换。
现有的拉头,其拉头座上安装有连接件和拉片,拉片与连接件是可活动的连接。如果拉链安装在服装上,在拉链的使用过程中,拉片会随着人们的运动而不断晃动,并对服装产生一定的拍打冲击,对运动者造成影响。同时也随着服装结构上的创新需求,袖口位置、裤脚位置等拉链装饰并能起到拉合作用,但是拉合后又不需要拉头的自由晃动,以免影响到日常的使用。
综上所述,如何对现有的拉头进行改进,以有效提高其稳定性,避免拉片的随意晃动,是目前本领域技术人员亟待解决的问题。
发明内容
有鉴于此,本发明的目的在于提供一种拉链头,能够有效提高稳定性,避免拉片在无作用力的情况下的自由翻转。本发明还提供了一种包括上述拉链头的拉链。
为了达到上述目的,本发明提供如下技术方案:
一种拉链头,包括:
拉头本体,用于开合链牙;
拉片,用于拉动所述拉头本体;
容纳部,设置在所述拉头本体上,并将所述拉片通过所述容纳部形成的容纳空间连接于所述拉头本体上表面;
弹性件,设置在与所述容纳部所形成的容纳空间相对应的所述拉头本体处,所述弹性件始终处于压缩状态,对所述拉片施加径向弹力以限制所述拉片的翻转。
优选的,所述拉片包括连接轴,所述连接轴设置在所述容纳部形成的容纳空间内,所述弹性件对所述连接轴施加径向弹力以限制所述连接轴的转动。
优选的,还包括容纳槽,所述弹性件设置在所述容纳槽内,所述容纳槽设置在与所述容纳部所形成的容纳空间相对应的所述拉头本体内。
优选的,所述拉头本体包括第一链牙道、第二链牙道和设置在所述第一链牙道与所述第二链牙道之间的基体,所述容纳部设置在所述基体上。
优选的,所述容纳槽设置在与所述容纳部所形成的容纳空间相对应的所述基体内。
优选的,所述弹性件为弹簧。
一种拉链,包括拉链头,所述拉链头为上述任意一项所述的拉链头。
根据上述的技术方案,可以知道,在本发明中,一种拉链头,包括:拉头本体,用于开合链牙;拉片,用于拉动拉头本体;容纳部,设置在拉头本体上,并将拉片通过容纳部形成的容纳空间连接于拉头本体上表面;弹性件,设置在与容纳部所形成的容纳空间相对应的拉头本体处,弹性件始终处于压缩状态,对拉片施加径向弹力以限制拉片的翻转。拉片在外力进行翻转过程中由于径向弹力的影响将使得翻转受到一定的阻尼和阻碍, 使拉片在翻转时具有一定的阻尼感,又由于弹性件的伸缩性,在外力的作用下可以使得拉片进行翻转,而当没有外力将拉片进行翻转时,由于弹性件的压缩状态提供的径向弹力的影响,拉片又将会被固定在容纳空间内,而不会随意的晃动或者翻转,从而限制拉片在无作用力下的自由翻转。
为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
请参阅图1-7,图1为本发明实施例所提供的第一种拉链头的结构示意图;图2为本发明实施例所提供的第一种拉链头的侧视图;图3为本发明实施例所提供的第一种拉链头的剖视图;图4为本发明实施例所提供的第一种拉链头的侧剖图;图5为本发明实施例所提供的第二种拉链头的剖视图;图6为本发明实施例所提供的第三种拉链头的剖视图;图7为本发明实施例所提供的第四种拉链头的剖视图。
如图1-7所示,在本发明的一个具体实施例中,一种拉链头,包括:拉头本体1,用于开合链牙;拉片2,用于拉动所述拉头本体1;容纳部3,设置在所述拉头本体1上,并将所述拉片2通过所述容纳部3形成的容纳空间4连接于所述拉头本体1上表面;弹性件5,设置在与所述容纳部3所形成的容纳空间4相对应的所述拉头本体1处,所述弹性件5始终处于压缩状态,对所述拉片2施加径向弹力以限制所述拉片2的翻转。弹性件5对拉片2的限制翻转作用具体应首先保证拉片2可以在容纳空间4内翻转,当拉片2在容纳空间4的任意位置进行翻转时,弹性件5均可与拉片2接触,由于弹性件5始终处于压缩状态,弹性件5会对拉片2施加一个径向方向的弹力,拉片2在外力进行翻转过程中由于径向弹力的影响将使得翻转受到一定的阻尼和阻碍,使拉片2在翻转时具有一定的阻尼感,又由于弹性件5的伸缩性,在外力的作用下可以使得拉片2进行翻转,而当没有外力将拉片2进行翻转时,由于弹性件5的压缩状态提供的径向弹力的影响,拉片2又将会被固定在容纳空间4内,而不会随意的晃动或者翻转,从而限制拉片2在无作用力下的自由翻转,而且与原先的多个零件组成的拉头相比,零件数量减少,拉头更简洁,组装起来更加方便、快捷。弹性件5可以设置在与容纳空间4相对应的拉头本体1上表面,如图5所示,通过与拉片2的接触对拉片2产生一个径向弹力,对拉片2的翻转产生一个阻尼和阻碍的作用,以限制拉片2在无作用力下的自由翻转,弹性件5还可以设置在与容纳空间4相对应的拉头本体1内部,如图3和4所示,以更好的容纳弹性件5,使得拉动拉片2进行翻转的时候,弹性件5在拉头本体1内部不容易脱落,通过对拉片2产生径向弹力,亦可以对拉片2的翻转产生一个阻尼和阻碍的作用,亦可以限制拉片2在无作用力下的自 由翻转,同时使得拉片2在不进行翻转的时候不晃动。其中弹性件5可以为气囊、弹性橡胶、热塑性弹性体或者弹簧,对于弹性件5的个数、长度、宽度等性能参数不做具体限制,只要能够起到相同的技术效果即可,容纳空间4可以是半开的,也可以是封闭的,容纳部3可以是分开的,也可以是一体的,如图5、6和7所示,拉片2只要能够通过容纳部3形成的容纳空间4连接于拉头本体1上表面,使得拉片2能够与拉头本体1接触,并完成拉动的工作即可,容纳空间4应首先保证拉片2不会从容纳空间4中脱落,能够更好的固定拉片2,使整个拉头更为稳定,并能够保证拉片2可以始终在容纳空间4内翻转,容纳空间4的设计为本领域的技术人员所熟知的现有技术,这里不再赘述。
在本发明的另一个具体实施例中,所述拉片2包括连接轴6,所述连接轴6设置在所述容纳部3形成的容纳空间4内,所述弹性件5对所述连接轴6施加径向弹力以限制所述连接轴6的转动。这里需要说明的是,连接轴6的截面形状不做具体限定,可以是圆形的也可以是方形的,连接轴6的具体结构和个数也不做限定,当连接轴6是一个,且是一个整体时,可以对应设置一个弹性件5,当连接轴6是两个,且是相互独立的整体时,可以对应设置两个弹性件5,当连接轴6是断开的两段结构时,可以对应着两段结构设置对应的两个弹性体或者多个弹性体,只要能够达到相同的技术效果即可,这里不再赘述。弹性件5以与连接轴6的中心处接触最优,从而使得对连接轴6施加的径向弹力能够与连接轴6的中心或者重心保持一致,以更好的作用于连接轴6,当然也可以不作用于连接轴6的中心处,只要能达到相同的技术效果即可。
在本发明的另一个具体实施例中,还包括容纳槽7,所述弹性件5设置在所述容纳槽7内,所述容纳槽7设置在与所述容纳部3所形成的容纳空间4相对应的所述拉头本体1内。容纳槽7的深度可以根据相应的需要进行设计,只要不穿透拉头本体1即可,根据拉头本体1的形状的不同,容纳槽7的宽度和深度也可以进行适应性调整,只要能够达到相同的技术效果即可,优选的,容纳槽7的宽度与容纳空间4的宽度一致,一方面使得弹性件5在容纳槽7内的放置更加的稳定,另一方面也可以减少拉头本 体1的加工,保证拉头本体1具有一定的强度,弹性件5的个数不做具体限定,可以是一个,也可以是多个,根据容纳槽7的大小可以进行适应性调整,只要能够达到相同的技术效果即可,根据实际设计的需要可以相应的进行个数的调整,为本领域技术人员所容易想到的,这里需要特别说明的是,容纳槽7不是通孔,也即既然是槽,必然不是孔,所以容纳槽7仅仅是在拉头本体1的表面有开口,必然不贯通拉头本体1,属于本领域技术人员所熟知的现有技术名词,这里不再赘述。具体的,弹性件5为弹簧,当弹性件5为弹簧时,弹簧的初始长度大于容纳槽7的深度,拉片2设置在容纳空间4内时,与弹簧接触,会对弹簧产生一定的压力,那么弹簧自然会对拉头产生一个径向弹力,在拉片2借助外力进行翻转时,拉片2受到径向弹力的作用将会受到一定的翻转限制,产生一定的翻转阻碍,当不借助外力翻转时,弹簧的径向弹力配合着容纳部3将会阻止拉片2的无作用自由翻转。
在本发明的另一个具体实施例中,所述拉头本体1包括第一链牙道8、第二链牙道9和设置在所述第一链牙道8与所述第二链牙道9之间的基体10,所述容纳部3设置在所述基体10上。所述容纳槽7设置在与所述容纳部3所形成的容纳空间4相对应的所述基体10内,基体10上的容纳部3可以形成用于容纳拉片2的连接轴6的容纳空间4,使得拉片2能够与拉头本体1接触,并完成拉动的工作,从而使得链牙可以在第一链牙道8与第二链牙道9之间进行张合,容纳槽7的深度小于基体10上下表面之间的高度,以更好的容纳弹性件5,使得拉动拉片2进行翻转的时候,弹性件5在基体10中不容易脱落,弹性件5放置在容纳槽7内始终处于压缩状态,从而会对放置在容纳空间4处的拉片2的连接轴6产生一个径向的弹力,在拉片2不借助外力进行翻转的时候,径向的弹力配合这容纳空间4的双重作用力,已将连接轴6进行压紧固定,从而限制拉片2在无作用力的情况下的自由翻转。
一种拉链,包括拉链头,所述拉链头为上述任意一项所述的拉链头。该拉链由于采用了上述拉链头,能够限制拉片2在无作用力的情况下的自由翻转,直接或间接的具有上述拉头所具有的技术效果。该拉链可以用于 衣服、鞋帽等需要开合及装饰的部位。
综上所述,本发明的拉链头,能够有效提高稳定性,避免拉片2在无作用力的情况下的自由翻转。
对所公开的实施例的上述说明,使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下,在其它实施例中实现。因此,本发明将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
