If you are familiar with decoration， You must learn more about expansion bolts。It is a common accessory for fixing objects，Usually used to fix the shelf or staircase on the wall，Although it is not big，But the effect is large, so everyone must want to know how it works.，Next， The editor will focus on the working principle of expansion bolts and the knowledge of installation steps and preventive measures.。You can refer to the editor's introduction！I hope that the editor's introduction can help everyone.！
principle：
Expansion boltHow to fix object？In fact， It relies only on the shape of the slope from me，Generate a certain binding force to withstand weight and secure object。The specific process is to insert the slot of the bolt into the hole on the wall.。Then lock nuts，at this time， Nut will pull the bolt out，Drag into the outer copper cylinder，at this time， The copper pipe will be pulled off to generate a certain binding force and secure it on the wall.，But this fix is not particularly reliable。If there is a dramatic vibration Expansion boltBe loose。
installation steps：
1。 First find the same alloy drill with the expansion bolt specification used。Then drill a hole with a drill on the wall or other mounting position，Clean up the dust in the hole。
2。 at this time， Install flat pad， Spring washer and nut are in place。Protection thread，Then insert the expansion bolt into the hole previously drilled.。
3。 At last， You only need to tighten the nut to complete the fixture。
Precaution：
1。 Drilling is the most basic，The most critical steps。Must pay attention to grasp the depth of the hole，usually，It is deep than the length of the expansion bolt5Millimeter，in short， The depth of the hole must be controlled to be greater than the length of the expansion bolt.。
2。 The requirements for installing the wall must be as strict as possible。This can better withstand strength。
3。 Generally， The force scope of ordinary size expansion bolts120易彤破壁机怎么样Kilogram510Kilogram。
The above is a knowledge about the principle of expansion bolts， Editor's installation steps and considerations。In fact， The working principle of expansion bolts is not complex。It is very easy to understand and its installation steps are very simple and convenient.，But the most important point to pay attention is，Everyone must fix it according to the maximum weight of it.。Remember not to be strange，Otherwise it will fall，therefore，I suggest you do not use expansion bolts to fix ceiling fans.。Everyone must remember everyone！
