There were many situations in which supermarkets opened the back door. From a business point of view, some supermarkets opened the back door to facilitate the shopping of residents in the community, thus increasing business income. For example, there were thousands of residents in the community. After opening the back door, residents could go to the supermarket to buy food, vegetables, and daily necessities without leaving the community. This was beneficial to retain customers. In terms of safety and management, it might bring hidden dangers. For example, some supermarkets could allow outsiders to enter the community at will after opening the back door, but the management of the community gate was strict. Outsiders normally needed to register, get the owner's consent, and check before entering the community. Opening the back door of the supermarket destroyed this safety management order and made the owner worry about safety issues. Moreover, opening the back door of the supermarket might also involve problems such as wall reconstruction. For example, some supermarkets would smash open the walls of the rented storefront houses and property houses along the street. The owners would worry about affecting the safety of the building. At the same time, it also involved the issue of whether the public income of the property rental could be informed to all the owners.

If the door is opened and there is a strange sound, it may be caused by the following reasons and corresponding measures can be taken to solve it: 1. ** Door Hinge (Hinge) Problem ** - ** Wear or Distortion **: When the door is folded, the door may be damaged or deformed due to excessive stress, resulting in abnormal noise. If it is worn out, you can consider applying grease and other consumables to the joints. If it is severely worn or deformed, you may need to replace the joints. - ** Lacking of Grease **: If the door is used for a long time, it will lack grease, and it is easy to produce strange sounds when the door is folded. In this case, you can first clean up the dust, sludge, and other impurities that may exist on the hinged parts, and then apply anti-rust lubricant, butter, etc. to make it slippery (do not use oil, oil is easily contaminated with oil, making the hinged parts more prone to problems). 2. ** Door stopper malfunction ** - ** Damage or Overstretch **: The door stopper may be overstretched or damaged when the door is folded back, resulting in an abnormal sound. If this is the case, you can check whether the stopper is rusted or stuck. If it is rusted, you can apply a lot of lubricant for smoothness. If the stopper is damaged, you may need to replace it. 3. ** Door Sealing Strip Problem ** - ** Shifted or damaged **: The door being folded back may cause the seal to shift or cause partial damage. When the door is opened and closed normally again, an abnormal sound will occur. If the sealing strip is displaced, try to reset it; if the sealing strip is damaged, decide whether to repair or replace the sealing strip according to the degree of damage. 4. ** Loosening of the door trim panel **: The external force of the door being folded back may cause the interior trim panel to loosen, causing an abnormal sound when the door is opened and closed. It can be judged by shaking the interior panel by hand or pressing the abnormal sound when driving. If it is the problem here, just tighten the interior panel again. 5. ** Door lock problem ** - ** Bad contact or displacement **: The door being folded back may affect the normal state of the lock block, resulting in bad contact or displacement, resulting in abnormal noise.
