具体实施方式Detailed ways
本发明提供了一种气管接头，其能够令发动机的生产成本得以降低，同时也能够避免压缩空气气源的浪费。The invention provides an air pipe joint, which can reduce the production cost of the engine and avoid the waste of compressed air sources.
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。The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
如图1所示，本发明实施例提供的气管接头，主要应用于发动机的压缩空气管路中，该气管接头主要包括连接管1、第一弹性件2、第二弹性件3、第一压块4和第二压块5(第一压块4和第二压块5均优选为具有通孔的圆柱结构)，其中，金属材质的连接管1具有允许第一气管插入的第一端，以及允许第二气管插入的第二端，第一弹性件2和第二弹性件3均设置在连接管1中，且第一弹性件2靠近第一端设置，以用于卡紧插入到第一端的第一气管，以实现第一气管与连接管1的密封连接，第二弹性件3靠近第二端设置，以用于卡紧插入到第二端的第二气管，以实现第二气管与连接管1的密封连接，而第一压块4设置在第一端，其能够被第一气管穿过，且第一压块4的两端中的一端，伸入至连接管1之外，另一端则位于连接管1内，同时第一压块4能够相对于连接管1进行伸缩，当操作人员向连接管1内按压第一压块4位于连接管1外部的一端时，第一压块4向连接管1内收缩，第一压块4位于连接管1内的一端会挤压被第二压块5抵接的第一弹性件2，从而在第一压块4和第二压块5的配合下令第二弹性件3发生弹性变形，而变形后的第一弹性件2则能够避让出空间，以使得第一气管不受阻挡的在连接管1内插入到位，之后撤去对第一压块4的按压力，第一弹性件2恢复原状，在此过程中，第一弹性件2将第一气管卡紧，从而实现第一气管与连接管1的密封连接，第一压块4在第一弹性件2的弹性作用下向连接管1外伸出，直至恢复至初始位置；第二压块5虽然滑动的设置在连接管1内，但是第二压块5与连接管1之间的摩擦力需要大于第一弹性件2的弹力，以保证第一弹性件2能够在第二压块5的抵接定位下被第一压块4挤压变形，当需要连接第二气管时，则可以与上述过程相同，再次向连接管1内按压第一压块4，当第一压块4挤压第一弹性件2完成弹性变形后，第一压块4与第二压块5实现刚性连接，此时继续对第一压块4施加足够的按压力，就可以令第一压块4推动第二压块5在连接管1内滑动，随着滑动的进行，第二压块5会挤压第二弹性件3发生弹性变形，使得第二弹性件3如第一弹性件2一般，给第二气管避让出空间，使得第二弹性件3不会再对第二气管形成阻挡而可以使第二气管在连接管1内插入到位，之后撤去按压力，使得第二弹性件3恢复原状，第二弹性件3就可以卡紧第二气管，从而实现第二气管与连接管1的密封连接，由于第二压块5的中心部位开设有连通孔，所以通过连通孔的连通可以实现第一气管与第二气管的密封连接。在第二弹性件3恢复原状的过程中，第二压块5在第二弹性件3弹力的作用下，反向滑动恢复至初始位置，第一压块4在第二弹性件3和第一弹性件2的弹力驱动下反向伸出，直至恢复至初始位置。当需要使连接管1与第一气管和/或第二气管分离时，重复上述操作，当第一弹性件2或第二弹性件3发生弹性变形时，第一弹性件2不再卡紧第一气管，第二弹性件3不再卡紧第二气管，第一气管和/或第二气管就能够从连接管1内退出。As shown in FIG. 1, the air pipe joint provided by the embodiment of the present invention is mainly used in the compressed air pipeline of the engine. The air pipe joint mainly includes a connecting pipe 1, a first elastic member 2, a second

The edge is provided with a plurality of teeth for clamping the first air pipe; the second
如图1所示，还优选第一压块4位于连接管1内的端部为管内端部，管内端部的外周壁与连接管1的内周壁之间具有第一容纳间隙6；第二压块5挤压第二弹性件3变形的端部为挤压端部，挤压端部的外周壁与连接管1的内周壁之间具有第二容纳间隙7。为了更好的保证第一压块4与第二压块5的刚性连接，以使得第二压块5能够在第一压块4的推动下顺畅滑动，优选增设了相对较大的第一容纳间隙6和第二容纳间隙7，使得变形后的部分第一弹性件2和部分第二弹性件3可以分别进入到第一容纳间隙6和第二容纳间隙7内，以令连接操作更加便利，省时省力。As shown in FIG. 1 , it is also preferable that the end of the first pressing block 4 located in the connecting pipe 1 is the inner end of the pipe, and there is a first accommodation gap 6 between the outer peripheral wall of the inner end of the pipe and the inner peripheral wall of the connecting pipe 1 ; The end where the
本实施例中，优选第一气管的直径大于第二气管的直径，与之相对应的，第二弹性件3的径向宽度大于第一弹性件2的径向宽度，从而使得内径较大的第一弹性件2能够卡紧较粗的第一气管，内径较小的第二弹性件3能够卡紧较细的第二气管，以通过本实施例提供的气管接头实现不同管径气管的连通。此外，第一气管和第二气管也可以为管径相同的气管，与之对应的第一弹性件2的尺寸与第二弹性件3的尺寸相同，即本实施例提供的气管接头也可以起到连通同管径气管的普通接头的作用。In this embodiment, the diameter of the first trachea is preferably larger than the diameter of the second trachea. Correspondingly, the radial width of the second
进一步的，如图1所示，第一压块4的外周壁上开设有第一凹槽8，连接管1的第一端部设置有伸入到第一凹槽8内的第一挡环9，该第一挡环9能够阻挡第一压块4从连接管1中完全脱出；同样的，第二压块5的外周壁上开设有第二凹槽10，连接管1的内周壁上凸出的设置有第二挡环11，该第二挡环11伸入到第二凹槽10中，以阻挡第二压块5在连接管1内过量滑动。其中，第一压块4在进行伸缩时，第一挡环9始终在第一凹槽8内滑动，从而使两者配合形成第一压块4与连接管1的限位结构；第二压块5在滑动时，第二挡环11始终在第二凹槽10内滑动，从而使两者配合形成第二压块5与连接管1的限位结构。此结构的设置，能够保证第一压块4与连接管1、第二压块5与连接管1的稳定配合，避免因相对过量移动导致连接失效或气管接头的损坏，令气管接头可以更加安全的进行工作。Further, as shown in FIG. 1 , the outer peripheral wall of the first pressing block 4 is provided with a first groove 8 , and the first end of the connecting pipe 1 is provided with a first retaining ring extending into the first groove 8 9. The first blocking ring 9 can prevent the first pressure block 4 from being completely disengaged from the connecting pipe 1; similarly, a
如图1所示，还优选连接管1的第二端为收缩端，且收缩端的外周壁上设置有螺纹12。此收缩端的内周壁可以用于抵接第二弹性件3，如图1所示，同时外周壁上设置的螺纹12，能够用于连接压缩空气管路中的其他部件，例如压缩空气的气源等。As shown in FIG. 1 , it is also preferred that the second end of the connecting pipe 1 is a constricted end, and a
