Description

一种易置入的磁性开关传感器及其安装结构 技术领域
本实用新型涉及传感器领域，尤其涉及一种易置入的磁性开关传感器及其安装结构。
 背景技术
开关传感器通常需要安装在底座上。传统的安装方式为：在底座上表面设置有贯穿底座前侧面、后侧面的沟槽，开关传感器从前侧面或后侧面插入沟槽内，使开关传感器安装在底座上。然而，传统的安装方式有以下缺点：开关传感器只能从底座前侧面、后侧面的一方插入沟槽，当底座前后长度比较长时，会使得插入后移至沟槽内位置的耗时较长，或当沟槽上方有其它机构阻挡时，会造成安装困难，如果底座在结构设计上没有前侧面、后侧面的开口，则传感器将无法从任一端置入沟槽，同时，开关传感器插入沟槽后，只能对左右方向进行固定，在发生震动时，开关传感器容易在前后方向偏移，导致位置发生改变，影响使用。并且传统的安装方式是用螺丝来固定传感器本体，因此在沟槽底部会形成因螺丝所造成的损伤，不利于反覆安装，也会造成检测精度降低。
 技术问题
本实用新型要解决的技术问题是根据上述现有技术的不足，提供一种易置入的磁性开关传感器及其安装结构，使得传感器安装简单方便，易于操作，结构更稳固可靠，可直接自底座沟槽上方任一处置入沟槽内，不再局限于必须从底座前侧面、后侧面的任一方置入，紧固效果更好，在维护阶段，即使空间狭小或有其它机构阻挡，也可轻松进行更换维护。

进一步地，所述卡位凸台的直径大于所述传感器本体的宽度。
进一步地，所述金属垫片与所述螺母之间设置有C型卡环；所述螺丝穿过所述金属垫片与所述螺母连接时，C型卡环卡于所述金属垫片与所述螺母之间，防止螺丝拧出时，与所述金属垫片脱落。
进一步地，所述螺丝的两端设置成无螺纹形状，防止所述螺丝拧出时，与所述金属垫片脱落。
一种易置入的磁性开关传感器的安装结构，所述传感器本体，安装在底座上；所述底座上表面设置有沟槽；所述卡位凸台随所述螺丝旋出而上升至恰可抵于所述底座侧壁时，使所述卡位凸台与所述底座沟槽侧壁贴紧，同时使所述传感器本体底部向下挤压，贴紧所述底座沟槽底部。
进一步地，所述沟槽横截面为“C”型或者“T”型结构。

 本发明的最佳实施方式
为使本实用新型的目的、技术方案和优点更加清楚，下面将结合附图对本实用新型作进一步地详细描述。
如图1-5所示，本实用新型提供的实施例，一种易置入的磁性开关传感器，包括有传感器本体1，传感器本体1上设置有一缺口，缺口上装配有螺丝2，金属垫片3和螺母4。金属垫片3两端固定在传感器本体1上，螺丝2穿过金属垫片3与螺母4连接。传感器本体1的缺口处侧面向传感器本体1两端凹陷，形成凹部5；螺母4两侧向外凸起，形成卡位凸台6；凹部5恰可容纳卡位凸台6。传感器本体1截面为 “U”型结构。
金属垫片3与螺母4之间设置有C型卡环9；螺丝2穿过金属垫片3与螺母4连接时，C型卡环9卡于卡于金属垫片3与螺母4之间，防止螺丝2拧出时，与金属垫片3脱落，使得螺丝2无论怎么拧都不会从金属垫片3里面掉出来了。
当螺母4上的卡位凸台6未旋出时，传感器本体1可沿垂直方向置入底座8的C型沟槽7内。如图4所示，旋转螺丝2，卡位凸台6随螺丝2旋出而上升至恰可抵于底座8侧壁时，卡位凸台6的直径大于传感器本体1的宽度，使卡位凸台6与底座8沟槽7侧壁贴紧，同时使传感器本体1底部向下挤压，贴紧底座8沟槽7底部。
传感器本体1，安装在底座8上；底座8上表面设置有沟槽7；沟槽7横截面为“C”型或者“T”型结构。
如图6所示，本实用新型提供另一实施例，一种易置入的磁性开关传感器。本实施例与另一实施例的区别在于：螺丝2的两端设置成无螺纹形状，螺丝2穿过金属垫片3与螺母4连接时，螺丝2在松懈的过程中利用前端无螺纹形状，可以使前端继续停留在螺母4内，螺丝2尾端设置成无螺纹，同样不会向上拧进金属垫片3内，这样可以防止螺丝2松懈拧出时与金属垫片3脱落，使得螺丝2无论怎么拧都不会从金属垫片3里面掉出来了。
以上所揭露的仅为本实用新型较佳实施例而已，当然不能以此来限定本实用新型之权利范围，因此依本实用新型权利要求所作的等同变化，仍属本实用新型所涵盖的范围。
 工业实用性
