一、执手：用于平开窗。主要的作用是在平开窗关闭后将平开窗压在窗框上，从而实现密封的作用。在选购，应该观察到表面是平坦的，没有毛刺，用手感觉重量，并且涂层表面是均匀的。

1、 Handle: used for casement windows. The main function is to press the casement window on the window frame after the casement window is closed, so as to achieve the function of sealing.

三、滑撑：支架支撑平开窗的开启、关闭和定位装置在选购时，使用不锈钢材料，表面不应有划痕、边缘和毛刺。当滑动支架打开和关闭时，一点阻力就足够了。

3、 Sliding brace: The opening, closing and positioning device of the support casement window shall be made of stainless steel when purchased, and the surface shall be free of scratches, edges and burrs. When the sliding bracket is opened and closed, a little resistance is enough.

四、滑轮：承受每个推拉式电动卷帘门的重量，并作水平运动。在选购，应注意皮带轮支架的材料以及皮带轮是否采用滚针轴承或滚珠轴承。滑动门滑轮应为重型门滑轮，不得用推拉窗滑轮代替。

4、 Pulley: bear the weight of each push-pull electric roller shutter door and make horizontal movement. When purchasing, pay attention to the material of pulley bracket and whether the pulley adopts needle bearing or ball bearing.

六、合页：要求特点具有强度高、承重能力强、拆装方便、开闭灵活、消音等特点。

6、 Hinge: The required features are high strength, strong bearing capacity, convenient disassembly and assembly, flexible opening and closing, and noise reduction.

七、密封条：因为门和门板的结合是板与板之间的硬碰硬，关门的瞬间噪音高达120分贝，严重影响身心健康。采用高强度密封条，不与油漆反应，保证接触油漆表面的光滑度。并且它还有减震，消音、密封、隔音、防潮等特点特色。

7、 Sealing strip: because the combination of door and door plate is a hard collision between plates, the instantaneous noise of closing the door is as high as 120 dB, which seriously affects physical and mental health.
