具体实施方式
下面结合附图并通过具体实施方式来进一步说明本文的技术方案。
本文提供一种内筒后端固定结构，如图1-3所示，该内筒后端固定结构包括法兰轴盘1、轴承室2、轴承3、加强板4以及防护盖5，其中：
如图4所示，上述法兰轴盘1包括轴11以及连接在轴11一端的法兰12，具体的，该轴11和法兰12可以一体成型，也可以分体设置。在本实施例中，上述法兰12固定套设在轴11上，在本实施例中，在法兰12上开设一第一长形孔，在轴11的一端两侧对称设置有平面111(图5所示)，通过平面111与第一长型孔的两侧壁相配合，能够将法兰12压装固定在轴11上，以使得两者之间不会出现相对转动，而且上述结构也降低了生产成本。
本实施例中，上述法兰12固定安装在干衣机的内筒后法兰6上，在一些实施例中，可通过螺栓连接方式将法兰12固定在内筒后法兰6上。
上述轴11的一端端部穿设在内筒后法兰6内，另一端则穿设在上述轴承3内，且能够随着轴承3的内圈同步转动。在本实施例中，可参照图3，上述轴11穿设在轴承3内的一端开设有螺孔112，第二螺钉9穿过平垫10后螺纹连接于螺孔112。在本实施例中，上述平垫10的直径大于轴承3的内圈的内径，当 第二螺钉9螺纹连接于螺孔112时，上述平垫10被压紧在轴承3的内圈端面上，使得轴11能够与轴承3的内圈同步转动。
本实施例中，上述轴承3安装在轴承室2内，上述轴承室2位于内筒后法兰6的外侧，且该轴承室2设置为与干衣机的固定板7固定连接。在一些实施例中，是通过多个螺栓将轴承室2与固定板7固定连接。
在本实施例中，可参照图3，上述加强板4位于内筒后法兰6内侧，且加强板4、内筒后法兰6以及法兰12三者之间通过螺栓固定连接。通过设置加强板4，能够有效提高内筒后法兰6与法兰12之间的连接强度。而且本实施例中，上述螺栓均从前方向后的方式安装，即从加强板4向法兰12的方向安装，这样能便于安装和维护时的拆卸。
如图6所示，本实施例在加强板4的中间位置处开设有长形孔42，该长形孔42的形状大小与轴11套设法兰12的一端的形状大小相匹配，该长形孔42的相对的两侧壁与上述轴11的两个平面111相贴合。通过该长形孔42以及轴11的两个平面111的设置，一方面能够使得轴11在安装时便于对孔，另一方面能够使得轴11与加强板4之间相对固定，不会发生相对转动。
可参照图7，上述防护盖5位于内筒后法兰6内侧，且防护盖5固接于轴11未穿设在轴承3内的一端端部，本实施例中，通过第一螺钉8将防护盖5与轴11的端部相连接。通过设置防护盖5，将加强板4以及螺栓均罩设在内，进而避免了螺栓以及加强板4的外露。
在一些实施例中，上述防护盖5的中间位置设有凹向轴11的凹槽51，上述第一螺钉8的头部位于凹槽51内，即上述第一螺钉8采用嵌入式方式安装在防护盖5的凹槽51内，能够有效地防止第一螺钉8刮伤衣物。
本实施例中，在防护盖5上设有限位卡扣52，相对应的，在加强板4上设有限位卡槽41(图6所示)，上述限位卡扣52扣合在限位卡槽41内。通过限位卡扣52以及限位卡槽41的设置，能够防止内筒转动时，衣物将防护盖5打松脱落。
本实施例的上述内筒后端固定结构在安装时，首先，将轴承室2固定在固定板7上，随后将轴11的一端穿设在轴承3内，并通过第二螺钉9以及平垫10使得轴11与轴承3的内圈同步转动。随后将法兰轴盘1与内筒后法兰6固定，即将加强板4、内筒后法兰6以及法兰轴盘1的法兰12三者之间通过螺栓固定，之后安装防护盖5并通过第一螺钉8固定在轴11上，同时通过限位卡扣52扣 合在加强板4的限位卡槽41内。
本文还提供一种干衣机，包括上述内筒后端固定结构，能够将轴承3设置在内筒后法兰6的外侧，能够有效地与内筒内的热风隔离，有效避免轴承3长期在潮湿而高温的环境下工作导致的寿命降低，防止轴承3产生故障。而且上述内筒后端固定结构采用从前往后的方式安装，便于安装以及维护。
