Description

一种用于喷涂设备的供液装置 技术领域
本实用新型涉及喷漆枪的流体供应，尤其涉及一种用于喷涂设备的供液装置。
背景技术
供液装置一般是指喷漆杯，喷漆杯用于贮存漆料，在使用时喷漆杯与喷枪连接将喷漆杯内部的油漆喷出。目前市面上有主要有两种喷漆杯：
一种是由杯体与杯盖构成的。
另一种是由刚性外杯、内衬、杯盖与螺纹固定环四部分构成的。需要将内衬放置在刚性外杯内，在通过杯盖封盖住内衬，最后通过螺纹固定环将刚性外杯、内衬与杯盖固定为一体式结构，再与喷枪联接，其安装步骤比较繁琐，更换过程比较复杂。尤其是螺纹固定环在旋转过程中，螺纹固定环与刚性外杯螺纹结合固定进而压紧盖子，但是由于盖子位于刚性外杯与螺纹固定环之间，螺纹配合时候容易出现紧固不到位的现象，在旋转安装喷枪时会造成盖子与刚性外杯之间的大幅度旋转，并且螺纹固定环紧固不够充分时，会导致喷漆杯无法固定。
因此，现有技术有待于更进一步的改进和发展。
实用新型内容
鉴于上述现有技术的不足，本实用新型的目的在于提供一种用于喷涂设备的供液装置，在保证供液装置牢固度的前提下，降低其制造成本。
为解决上述技术问题，本实用新型方案包括：
一种用于喷涂设备的供液装置，其包括：
具有流体出口的盖，所述流体出口适用于将所述盖联接到所述喷涂设备；
具有凸缘的内衬，当从所述供液装置吸取包含在所述内衬内的流体时所述内衬坍塌；
具有开口端的刚性外杯，其中所述盖在所述开口端上延伸并且所述内衬被接收在所述刚性外杯中，所述盖与所述刚性外杯、所述内衬相适配；
其中，所述盖的外沿上均匀布置有若干个螺旋楔形元件；所述刚性外杯内壁 的上沿均匀布置有若干个螺旋楔形槽隙；螺旋楔形元件与螺旋楔形槽隙相适配且一一对应；螺旋楔形元件旋入螺旋楔形槽隙内，所述盖与所述刚性外杯相联接。
所述的供液装置，其中，上述盖上均匀布置有四个螺旋楔形元件。
所述的供液装置，其中，上述螺旋楔形槽隙由单向突起形成，单向突起朝所述刚性外杯之开口端的圆心方向突起；单向突起的上表面与所述刚性外杯内壁的上沿之上表面位于同一个平面，单向突起的下表面为螺旋面，该下表面朝向刚性外杯之杯底。
所述的供液装置，其中，上述螺旋楔元件和螺旋楔形槽隙分别只是相应的外螺纹和内螺纹的一圈的一部分的形式。
所述的供液装置，其中，上述若干个螺旋楔形槽隙下方之所述刚性外杯内壁的对应处设置有用于放置所述内衬之凸缘的放置环面。
所述的供液装置，其中，上述盖的中部向上隆起形成一穹顶部，上述流体出口设置在该穹顶部的顶端，该穹顶部的周面上设置有若干个与手指部之人体工学相匹配的凹陷处。
所述的供液装置，其中，上述流体出口上设置有与喷涂设备联接方式相适配的连接部。
所述的供液装置，其中，上述盖的对应处设置有与内衬之开口相匹配的封闭部。
所述的供液装置，其中，上述螺旋楔形槽隙的末端设置有止档片；上述螺旋楔形元件的长度为1厘米-2厘米之间，螺旋楔形元件的断面为梯形或三角形。
所述的供液装置，其中，上述四个螺旋楔形元件为相同的螺旋楔元件。
本实用新型提供的一种用于喷涂设备的供液装置，采用刚性外杯、内衬与盖子的结构方式代替传统技术中四个部件的方式，减少了一个部件，降低了供液装置的制造成本，减少了零部件安装过程，方便了工人操作，在盖上设置若干个较短的螺旋楔形元件，在刚性外杯对应处设置相应的螺旋楔形槽隙，螺旋楔形元件旋入螺旋楔形槽隙中，即可完成盖与刚性外杯的联接，又由于本实用新型中螺旋楔形元件均匀布置在盖的边沿处，长度较短，减少了盖子转动的行程，避免了内衬出现过度变形的状况。

具体实施方式
本实用新型提供了一种用于喷涂设备的供液装置，为使本实用新型的目的、技术方案及效果更加清楚、明确，以下对本实用新型进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
本实用新型提供了一种用于喷涂设备的供液装置，如图1、图5与图6所示的，包括：具有流体出口1的盖2，所述流体出口1适用于将所述盖2联接到所述喷涂设备；喷涂设备一般是指喷漆枪，盖2一般采用注塑一体成型，当然也可以采用其他形式。具有凸缘3的内衬4，当从所述供液装置吸取包含在所述内衬4内的流体时所述内衬4坍塌，内衬4也称为内杯，一般是注塑成型，壁比较薄，随着其内的液体流出，在大气压的作用下会坍塌。
具有开口端5的刚性外杯6，其中所述盖2在所述开口端5上延伸并且所述内衬4被接收在所述刚性外杯6中，所述盖2与所述刚性外杯6、所述内衬4相适配；
尤其是，如图3所示的，所述盖2的外沿上均匀布置有若干个螺旋楔形元件7；如图5所示的，所述刚性外杯6内壁的上沿均匀布置有若干个螺旋楔形槽隙8；螺旋楔形元件7与螺旋楔形槽隙8相适配且一一对应；螺旋楔形元件7旋入螺旋楔形槽隙8内时，所述盖2与所述刚性外杯6相联接。操作工人也可以先行将螺旋楔形元件7轻微旋入对应螺旋楔形槽隙8内一部分，在流体出口1与喷漆枪的联接部旋紧后，利用喷漆枪进行转动，迅速使螺旋楔形元件7与螺旋楔形槽 隙8紧密结合。
更进一步的，上述盖2上均匀布置有四个螺旋楔形元件7，当然也可以设置两个螺旋楔形元件7，由于只有两个受力点，在内衬4内装满油漆等流体时，容易导致所述盖2另外两侧出现晃动的情况，使得所述盖2与刚性外杯6发生错位，无法使用。显然的也可以设置五个、六个或八个螺旋楔形元件7，使得所述盖2与刚性外杯6结合更加牢固，但大幅增加了制造成本，减低了市场竞争力。显然的，所述刚性外杯6上螺旋楔形槽隙8的数量与螺旋楔形元件7的数量相同。
在本实用新型的较佳实施例中，如图5与图6所示的，上述螺旋楔形槽隙8由单向突起形成，单向突起朝所述刚性外杯6之开口端5的圆心方向突起，具体的是外轮廓为弧形，与所述刚性外杯6的边沿相适配；单向突起的上表面9与所述刚性外杯6内壁的上沿之上表面10位于同一个平面，单向突起的下表面17为螺旋面，该下表面17朝向刚性外杯6之杯底。也就是说螺旋楔形槽隙8是由单向突起与刚性外杯6内壁的内表面形成，其与螺旋楔形元件7相适配。当多个螺旋楔形元件7旋入对应螺旋楔形槽隙8内时，使所述盖2与所述刚性外杯6牢固的联接在一起。并且更为具体的是：上述螺旋楔元件7和螺旋楔形槽隙8分别只是相应的外螺纹和内螺纹的一圈的一部分的形式，进而使螺旋楔元件7和螺旋楔形槽隙8的连接更为流畅。
更进一步的，上述若干个螺旋楔形槽隙8下方之所述刚性外杯6内壁的对应处设置有用于放置所述内衬4之凸缘3的放置环面11，也就是说螺旋楔形槽隙8与放置环面11之间存在适当的距离，避免了放置所述内衬4时造成放置失误，能够使所述内衬4与所述刚性外杯6更好的结合在一起，并且在压紧所述盖2时，不会造成内衬4的相对变形与位移。
为了更好的使螺旋楔元件7和螺旋楔形槽隙8相结合，如图2与图4所示的，在本实用新型的另一较佳实施例中，还可以使上述盖2的中部向上隆起形成一穹顶部12，上述流体出口1设置在该穹顶部12的顶端，该穹顶部12的周面上设置有若干个与手指部之人体工学相匹配的凹陷处13。可以设置三个或四个等相应数目的凹陷处13，在使用时，操作人员可以将手指抓紧凹陷处13旋拧所述盖2，使螺旋楔元件7和螺旋楔形槽隙8紧固在一起，再利用喷漆枪的转动迅速使螺旋楔形元件7与螺旋楔形槽隙8更紧密的结合一起。当拆卸时，可以利用喷漆 枪的转动使所述盖2与所述刚性外杯6相脱离。
尤其是，上述螺旋楔形槽隙8的末端设置有止档片14，避免了操作人员旋拧过度，使螺旋楔元件7脱离了螺旋楔形槽隙8的限制。螺旋楔形元件7的断面为梯形或三角形，保证了螺旋楔形元件7对应表面与单向突起的下表面17更紧密的结合，而且上述螺旋楔形元件7的长度为1厘米-2厘米之间，进而控制了螺旋楔形元件7的旋转行程，使所述盖2与所述刚性外杯6产生较小的位移，不会造成内衬4的相对变形与位移。最为优选的是，螺旋楔形元件7靠近所述盖2的弧形部分的长度为1.5厘米，远离所述盖2的弧形部分的长度为1.2厘米，靠近所述盖2的弧形部分之厚度大于远离所述盖2的弧形部分之厚度。一般采用上述四个螺旋楔形元件7为相同的螺旋楔元件，使螺旋楔形元件7与螺旋楔形槽隙8更流畅、更稳定的结合在一起。当然也可根据需要，设置不同形状的螺旋楔形元件7以及不同形状的螺旋楔形槽隙8，使得两者之间进行结合时兼具有定位的功能，防止了误操作。
更进一步的，上述流体出口1上设置有与喷涂设备联接方式相适配的连接部15，本实施例中连接部15的连接卡抓为T形，当也可以采用倒T形、螺旋片、抓钩等相应的形式，现有技术中关于对接的方式较多，在此不在一一赘述。
尤其是，如图3、图4与图7所示的，上述盖2的对应处设置有与内衬4之开口相匹配的封闭部16，在本实施例中，如图8所示的，封闭部16采用的是膨胀环18的方式，其口径略大于内衬4之开口，依靠内衬4之开口柔性，完成密封。同步的，螺旋楔形槽隙8与放置环面11之间存在适当的距离，当螺旋楔形元件7旋入螺旋楔形槽隙8时，螺旋楔形元件7会对所述内衬4之凸缘3形成持续的压力，与封闭部16相互配合，使所述盖2与所述内衬4之开口结合的更加紧密。
当然，上述说明并非是对本实用新型的限制，本实用新型也并不仅限于上述举例，本技术领域的技术人员在本实用新型的实质范围内所做出的变化、改型、添加或替换，也应属于本实用新型的保护范围。
