综上所述， 左门板 10、 右门板 11与隔板门框 6之间、 隔板门框 6与车 厢内表面之间采用胶条密封完好， 门板采用聚氨酯材料作保温层， 隔温门整 体隔温效果明显， 有利于不同温区温度的保持， 减少不必要的损耗。 In summary, between the left door panel 10, the right door panel 11 and the partition door frame 6, the partition door frame 6 and the inner surface of the compartment are sealed by a rubber strip, and the door panel is made of a polyurethane material as an insulation layer, and the temperature of the partition door is entirely insulated. The effect is obvious, which is beneficial to the maintenance of temperature in different temperature zones and reduces unnecessary losses.
隔温门的重量主要由顶导轨 14承载， 避免了常见的四条导轨同时承重 的弊端， 安装调试筒单， 降低了对厢体组装精度的要求。 The weight of the temperature-isolated door is mainly carried by the top rail 14 to avoid the disadvantages of the common four rails at the same time, and the installation and commissioning of the cylinders reduces the requirements for the assembly accuracy of the car body.
目前市场上常见的移动隔温门结构均为每条导轨单个滑轮， 在推动时 4艮 容易因为用力不平衡， 导致隔温门出现偏斜， 推动困难， 滑轮也易损坏。 作 为改进， 在每条导轨上安装滑轮对， 分别安装在隔板门框 6前后两面， 将以 往的单点导向运动变成线性导向运动， 限制了隔温门以滑轮拉杆为转轴的转 动， 能有效防止隔温门在移动过程中因受力不平衡导致的偏转， 保证隔温门 左右及上下方向在推动过程中的平衡， 使得整个隔温门推动轻便、 顺畅， 同 时多个滑轮分担隔温门重量， 可延长滑轮的使用寿命。 At present, the common moving door structure on the market is a single pulley for each rail. When pushing, it is easy to be unbalanced due to the unbalanced force, which causes the temperature of the door to be skewed, which is difficult to push and the pulley is easily damaged. As an improvement, a pair of pulleys are mounted on each of the guide rails, and are respectively mounted on the front and rear sides of the partition door frame 6, and the conventional single-point guiding motion is changed into a linear guiding motion, which limits the rotation of the heat insulating door with the pulley rod as a rotating shaft, which can effectively Prevent the deflection of the temperature-isolated door due to the unbalanced force during the movement, ensure the balance between the left and right and the up-and-down direction of the temperature-sensing door during the pushing process, so that the entire temperature-sensing door is light and smooth, and the multiple pulleys share the temperature-isolated door Weight, can extend the life of the pulley.
隔温门的限位充分利用了导轨的结构特点， 在滑轮边缘采用螺栓可锁紧限位 在导轨的任意位置， 不破坏导轨， 不需在车厢板上开孔， 操作筒单易行， 限 位可靠。
The limit of the temperature-isolated door makes full use of the structural features of the guide rail. The bolts can be locked at any position on the guide rail at the edge of the pulley. The guide rail is not damaged, and the hole is not required to be opened on the panel. The operation cylinder is easy to operate. Reliable.
