[25] 具体实施方式
[26] 下面结合附图对本实用新型作进一步的详细说明。
[27] 本实用新型为新型拉手部件固定结构， 实现拉手安装简便， 可靠， 保持外观精 美。
[28] 如图 1所示， 本实用新型的结构包括设于门外壳 1上的拉手 2及设于门外壳内 1的 发泡层， 还包括与拉手 2连接的卡座 3及设于门外壳 1内的加强铁 6， 该卡座 3通过 设于门外壳 1上的通孔 11与加强铁 6卡扣配合， 该加强铁 6固定于发泡层上。 其中 ， 该卡座 3与拉手 2的端部通过螺纹配合连接。 如图 2a及图 2b所示， 拉手部件不需 要螺钉固定， 门外壳 1发泡后安装拉手， 将其滑入门外壳 1内部的加强铁 6卡槽中 ， 实现安全自锁。 [29] 如图 3a、 3b及 3c所示， 该加强铁 6包括自锁弹片 61及卡座过孔 62， 该自锁弹片 6 1将卡座 3压入卡紧在卡座过孔 62内。 该自锁弹片 61为弹簧钢片， 该卡座过孔 62 包括相连通的大卡座过孔 63及小卡座过孔 64， 自锁弹片 61位于大卡座过孔 63出 口处， 且自锁弹片 61的端部与大卡座过孔 63及小卡座过孔 64的连接处平齐。
[30] 如图 4所示， 该加强铁 6通过定位凸台 65与设于门外壳 1上的定位凸台孔 12配合 固定。 门外壳 1留有通孔 11和定位凸台孔， 便于安装固定加强铁 6。
[31] 如图 5所示， 该卡座 3包括与设于拉手 2端部的螺纹孔 21配合的螺栓 31及与自锁 弹片 61卡位配合的卡位凸块 32。 该卡位凸块 32呈圆台结构， 与加强铁 6上的自锁 弹片 61配合， 实现固定拉手 2的功能； 且其顶部设有十字槽 34， 方便工具操作。 卡座 3与拉手 2装配效果如图 6所示。
[32] 如图 7所示， 该加强铁 6与发泡层之间设有隔离作用的后盖 7。
[33] 本实用新型的装配过程： 首先将加强铁 6与门外壳 1通过定位凸台 65和定位凸台 孔 12对齐， 用胶带粘贴固定。 然后用后盖 7将加强铁 6的自锁弹片 61处遮档住。 用胶带粘贴紧， 防止发泡材料接触到自锁弹片 61部位。
[34] 门体完成发泡后， 加强铁 6和后盖 7已经被发泡料固定。 装配拉手 2及卡座 3: 将 卡座 3的卡位凸块 32缓慢用力插入加强铁 6的大卡座过孔 63中， 直至卡座 3的卡位 凸块 32的底面与加强铁 6外表面平齐， 此吋加强铁 6的自锁弹片 61被卡座 3的卡位 凸块 32弹起。 然后将拉手 2及卡座 3向小卡座过孔 64方向滑动， 这个过程中， 由 于良好的弹性， 自锁弹片 61会逐渐恢复形变， 压住卡座 3的卡位凸块 32。 滑到底 端后， 自锁弹片 61将卡座 3压紧， 整个过程完成。 完成装配后结构的如图 8所示
