技术领域
本发明涉及一种固定装置，尤其是涉及一种发光条固定装置和螺旋弹簧。
背景技术
发光条作为LED灯的发光光源，其在发光的过程中会产生大量的热量，为了驱散发光条产生的热量，通常的做法是将发光条固定在散热机构上，通过散热机构驱散热量，防止发光条因温度过高，而烧坏或缩短使用寿命。
现有技术中，将发光条与散热机构进行固定的方式一般包括两种：(1)、通过螺丝将发光条与散热机构固定。（2）、通过导热双面胶将发光条与散热机构粘接固定。
但是，上述方式均存在如下问题：在使用过程中螺丝容易松动，发光条与散热机构接触不良，使发光条与散热机构之间存在空隙，导致发光条的散热不均匀，使得发光条自身的温度不均匀，最终导致发光条所发出的光频谱不一，甚至因局部过热而缩短发光条的使用寿命。
发明内容

优选地，所述螺旋弹簧的柱身外径大于所述螺纹孔的大径。
优选地，所述螺旋弹簧的柱身具有锥度。

图4是本发明第二实施例的螺旋弹簧使用状态的结构示意图；

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参见图1、图2和图3，提出本发明第一实施例的发光条固定装置100，包括发光条110和散热机构120，所述发光条110上设置有通孔111，所述散热机构120设置有与通孔111位置对应的螺纹孔121；所述发光条固定装置100还包括一螺旋弹簧130，该螺旋弹簧130的节距131与所述螺纹孔121的节距一致，其柱身可旋入所述螺纹孔，止端133外径大于柱身外径，且水平盘整在尾端132。
所述止端133可以是一圈或几圈外径大于柱身外径的螺旋弹簧圈。因止端133因外径大于柱身外径，因此，其可以控制螺旋弹簧130在外力的拧动下停止向发光条110方向旋入。如在安装所述发光条固定装置100时，将螺旋弹簧130由前端134穿过发光条110的通孔111，并在外力的拧动下旋入散热机构120中对应的螺纹孔121内。当止端133与发光条110顶持接触时，则螺旋弹簧130不能在外力的拧动下继续向散热机构120方向旋入。
进一步地，本发明第一实施例的发光条固定装置100中，所述螺旋弹簧130的前端134起始部向内弯折，形成一字形拧动施力部136。
参见图4，所述螺旋弹簧130尾端132与前端134之间贯穿设置一通孔135，通过一拧动治具200穿过所述通孔135对拧动施力部136施加一拧动动力，便可将螺旋弹簧130旋入散热机构120的螺纹孔121内，实现发光条110与散热机构120紧固连接。
进一步地，上述发光条固定装置100中，所述拧动施力部136还可以为“十”字形、“米”字形，或多边形。所述多边形可以为三角形、等边六边形杆件等等。
参见图4，所述拧动治具200包括手持端部210和工作端部220，该工作端部220设置有纳置拧动施力部136的凹槽221。在安装所述发光条固定装置100时，将拧动治具200的工作端部220穿入螺旋弹簧130的通孔135内，使工作端部220的凹槽221与拧动施力部136适配卡合，然后旋转拧动治具200的手持端部210，将螺旋弹簧130由前端134穿过发光条110的通孔111，并旋入散热机构120中对应的螺纹孔121内。
进一步地，参见图5，所述发光条固定装置100实施例中，构成螺旋弹簧130的弹簧丝具有牙型角137，且所述弹簧丝的牙型角137等于或大于所述螺纹孔121的牙型角。所述弹簧丝的牙型角137大于所述螺纹孔121的牙型角，则通过外力将螺旋弹簧130旋入螺纹孔121时，弹簧丝的牙型角137与螺纹孔121中对应的牙型角顶持接触，从而使螺旋弹簧130产生收缩变形，产生反弹力，从而与螺纹孔121紧密啮合。这种啮合方式不易产生松动，能够保证发光条110与散热机构120长时间保持紧固连接。减少了发光条110与散热机构120之间的空隙，保证了发光条110通过散热机构120实现均匀散热，使发光条110的温度分布均匀，从而保证了发光条110的发光效果，延长了发光条110的使用寿命。
在本发明的第一实施例中，也可设置螺旋弹簧130的柱身外径大于螺纹孔121的大径。使将螺旋弹簧130旋入所述螺纹孔121时，受所述螺纹孔121的挤压而产生变形，使旋入螺纹孔121中的螺旋弹簧圈外径尺寸缩小至螺纹孔121大径尺寸，产生反向弹力，从而进一步加强了发光条110与散热机构120的紧固度。
进一步地，上述发光条固定装置100实施例中，螺旋弹簧130的柱身具有锥度。即螺旋弹簧130的柱身由尾端132至前端134，其外径逐渐变小，将螺旋弹簧130旋入螺纹孔121的过程中，由于前端134的外径较小，可较易旋入，慢慢则需要较大的外力旋入，在旋入的过程中，螺旋弹簧130与螺纹孔121之间的顶持压力也越来越大，从而使螺旋弹簧130与螺纹孔121啮合的越来越紧密，使发光条110与散热机构120紧固连接。
进一步地，上述发光条固定装置100实施例中，所述螺旋弹簧130各圈之间紧邻。所述螺旋弹簧130可由金属丝缠绕而成，该螺旋弹簧130上两两相邻的金属圈紧密接触。螺旋弹簧130上的节距131大小为两相邻金属圈之间的距离。
本发明的上述实施例中，由于螺旋弹簧130柱身具有弹性，将螺旋弹簧130旋入螺纹孔121后不易松动。因此通过本实施例，可实现发光条110与散热机构120紧固连接，减少了发光条110与散热机构120之间的空隙，保证了发光条110通散热机构120实现均匀散热，使发光条110的温度分布均匀，从而保证了发光条110的发光效果，延长了发光条110的使用寿命。
进一步地，参见图3，提出本发明第二实施例的螺旋弹簧130。螺旋弹簧130，其节距131与螺纹孔的节距一致，柱身可旋入所述螺纹孔，止端33的外径大于柱身外径，且水平盘整在尾端132。
本发明的上述实施例中，由于螺旋弹簧130具有弹性，螺旋弹簧130旋入螺纹孔后不易松动。因此通过使用本实施例的螺旋弹簧130固定两个分离的物件，可保证该两物件能够保证长时间的紧固连接。若应用于发光条固定装置100中，可实现发光条110与散热机构120紧固连接，减少发光条110与散热机构120之间的空隙，保证发光条110通过散热机构120实现均匀散热，使发光条110的温度分布均匀，从而可保证发光条110的发光效果，延长发光条110的使用寿命。
进一步地，所述螺旋弹簧130的前端134起始部向内弯折，形成一字形拧动施力部136。其中，所述螺旋弹簧130即为发光条固定装置100中的螺旋弹簧130，在此不再赘述。
应当理解的是，以上仅为本发明的优选实施例，不能因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
