Description

一种螺纹固定结构 技术领域
本发明属于汽车配件技术领域，尤其涉及一种螺纹固定结构。
背景技术
汽车轮胎(和轮辋)气门嘴是按标准安装的配件，其功能是给轮胎充气(或液体)、放气和密气。在原有轮胎气门嘴上加载外接气门嘴用于搭载如气压表、监测胎压和温度传感器、轮胎自动补气装置、充气延伸管等是为了增加方便充放气、保持轮胎气压、监控轮胎气压、温度等功能。汽车在气门嘴上加载测胎压的胎压计(如图1所示)、汽车在气门嘴上监测胎压的传感器(如图2所示)等。连接方式常见的有焊接方式、螺纹连接等。螺纹连接的两个零部件，中间可以是密封胶，也可是密封圈来保证密封，防止两零件松动脱开，常规的方法是：1、在螺纹中间涂螺纹胶固定；2、在两零件的平面上涂金属胶固定。连接方式是焊接方式的，加工工艺复杂，参数要求高，不良检验困难，可靠性比较差；连接方式采用螺纹连接、胶水防松的，由于胶水在一定的环境下容易失效，产品的密封性就难以得到保证。
发明内容
本发明目的在于解决现有技术中存在的上述技术问题，提供一种螺纹固定结构，能够提高底座和气门嘴之间的连接效果，避免底座与气门嘴之间松动。
一种螺纹固定结构，其特征在于：包括气门嘴、底座和密封圈，气门嘴和底座螺纹连接，密封圈设于气门嘴和底座之间，在气门嘴和底座螺纹连接完成后在底座与气门嘴贴合的面冲压形成固定凸起部，固定凸起部陷入气门嘴中以限制底座和气门嘴之间的相对转动。通过固定凸起部对气门嘴和底座进行限位，相互锁死，使得二者之间不会产生相对转动，从而使得气门嘴和底座的螺纹连接不会产生松动，提高了底座和气门嘴的连接效果。从底座上方冲压，能够使得冲压更加方便，提高冲压效率，节约成本。在冲压底座时，底座形变形成固定凸起部，同时固定凸起部陷入气门嘴，使气门嘴形成固定槽。
进一步，气门嘴设有密封槽，密封圈设于密封槽中。通过密封槽的设置，能够便于固定防止密封圈，同时能够保证密封圈与气门嘴、底座的贴合程度，提高密封效果。
进一步，底座设有连接柱，连接柱设有外螺纹，气门嘴设有连接孔，连接孔设有内螺纹，连接柱与连接孔螺纹连接。通过连接柱和连接孔的设置，方便底座和气门嘴的连接。
进一步，气门嘴设有第一连接面，底座设有第二连接面，第一连接面和第二连接面相贴合。通过第一连接面和第二连接面的设置使得气门嘴和底座之间紧密接触无缝隙，能够保证气门嘴和底座的连接密封效果，避免泄露。
进一步，连接柱设有通气孔以实现气门嘴与底座之间的连通。通气孔的设置，能够实现气门嘴和底座之间的连通，便于底座上的传感器监测气门嘴上的气压。
进一步，底座设有环状凸起部，环状凸起部与底座形成容纳槽。通过容纳槽的设置，便于传感器在底座上的定位和固定，方便了传感器的安装。
进一步，固定件部为固定销，气门嘴设有第一固定孔，底座设有第二固定孔，第一固定孔和第二固定孔位置相对应，固定销穿过第二固定孔并设于第一固定孔中。固定件采用固定销的形式，同样能够使得底座和气门嘴之间相互锁死，不发生相对转动，起到防松的效果。
本发明由于采用了上述技术方案，具有以下有益效果：
本发明在使用时，先将密封圈置于密封槽中，之后将连接柱对准连接孔并拧入，拧紧之后，在底座的底部上冲压，使得底座的底面凸起形成固定凸起部，连接平面凹陷形成固定槽，从而实现底座和气门嘴的相互锁死，从而避免底座和气门嘴之间的松动。本发明能够提高底座和气门嘴之间的连接效果，避免底座与气门嘴之间松动。

底座设有连接柱，连接柱设有外螺纹，气门嘴设有连接孔，连接孔设有内螺纹，连接柱与连接孔螺纹连接。通过连接柱和连接孔的设置，方便底座和气门嘴的连接。
气门嘴设有第一连接面，底座设有第二连接面，第一连接面和第二连接面相贴合。通过第一连接面和第二连接面的设置使得气门嘴和底座之间紧密接触无缝隙，能够保证气门嘴和底座的连接密封效果，避免泄露。第一连接面和第二连接面可以为平面，也可以为相互贴合的球面。
连接柱设有通气孔以实现气门嘴与底座之间的连通。通气孔的设置，能够实现气门嘴和底座之间的连通，便于底座上的传感器监测气门嘴上的气压。
底座设有环状凸起部，环状凸起部与底座形成容纳槽。通过容纳槽的设置，便于传感器在底座上的定位和固定，方便了传感器的安装。
通过一次冲压成型的固定凸起部和固定槽配合，加工较为方便，同时固定凸起部和固定槽的配合程度高，互锁效果好。
本发明的结构多用于两螺纹连接时，在振动的过程中或高速运转的过程中，需保证两连接件不能相互移动或松动。
振动试验：试验在电动振动试验机上进行，将本发明结构件固定在试验治具上，以频率8～10Hz、位移幅值15mm正弦振动2min，重复3次，卸下结构件观察无松动、无位移。
本发明在使用时，先将密封圈置于密封槽中，之后将连接柱对准连接孔并拧入，拧紧之后，在底座的底部上冲压，使得底座的底面凸起形成固定凸起部，连接平面凹陷形成固定槽，从而实现底座和气门嘴的相互锁死，从而避免底座和气门嘴之间的松动。本发明能够提高底座和气门嘴之间的连接效果，避免底座与气门嘴之间松动。
以上仅为本发明的具体实施例，但本发明的技术特征并不局限于此。任何以本发明为基础，为解决基本相同的技术问题，实现基本相同的技术效果，所作出的简单变化、等同替换或者修饰等，皆涵盖于本发明的保护范围之中。
