[0001] This utility model relates to the field of power adapter technology, specifically a multi-interface power adapter for building applications. Background Technology

[0002] With the rapid development of intelligent and information-based modern buildings, the number and types of electrical equipment in buildings are increasing day by day. From daily office equipment, such as computers, printers, and fax machines, to equipment that ensures the safety and normal operation of buildings, such as surveillance cameras, access control systems, and fire alarm devices, to lighting systems and air conditioning equipment that provide a comfortable environment for people, all these devices require a stable and reliable power supply. However, the power interface specifications of different devices vary greatly. Traditional power sockets often only provide standard AC power interfaces, while the plug shape, size, voltage, and current requirements of various devices are different. This often leads to the need to equip various adapter plugs or converters when using these devices, increasing the cost of use and management difficulty. Furthermore, existing power adapters may allow dust or water to enter through the socket, causing damage to internal components, affecting normal use, and even causing safety accidents. To solve the above problems, a multi-interface power adapter for buildings is needed.

[0003] An existing multi-interface power adapter for buildings has the problem that it cannot provide sealing protection for the sockets or protection against being stepped on when the external power cord is in operation. Therefore, there is an urgent need for a multi-interface power adapter for buildings. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a multi-interface power adapter for buildings, so as to solve the problems that existing multi-interface power adapters for buildings cannot provide sealing protection for the sockets or protection against trampling on the external power cords during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-interface power adapter for building applications, comprising a device body, an external power cord installed on the side wall of the device body, a protective sleeve installed on the outer wall of the external power cord, a slot formed on the side wall of the protective sleeve, a connecting rod installed on the side of the protective sleeve away from the slot, an adhesive patch installed at the bottom of the protective sleeve, a limiting rod installed on the side wall of the device body, a return spring installed on the outer wall of the limiting rod, a protective sleeve installed on the top of the device body, a limiting block installed on the inner side wall of the protective sleeve, a limiting spring installed on the inner wall of the device body, and a limiting lever installed on the outer wall of the limiting spring.

[0006] Preferably, the protective sleeve is connected to the external power cord, and the protective sleeve is elastically designed.

[0007] Preferably, the slot engages with the connecting rod, and the protective sleeve is bonded to the adhesive patch.

[0008] Preferably, the limiting block forms a telescopic structure with the limiting rod via a reset spring, and the limiting block is slidably connected to the main body of the device.

[0009] Preferably, the limiting rod is symmetrically arranged with the central axis of the device body as the center, and the bottom of the protective sleeve is tightly fitted with the top of the device body.

[0010] Preferably, the limiting rod forms a telescopic structure with the main body of the device through a limiting spring, and the limiting rod is engaged with the protective sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses an external power cord, a protective sleeve, a slot, a connecting rod, and an adhesive patch to connect the protective sleeve to the external power cord. Then, the connecting rod is inserted into the slot according to the length of the external power cord to extend the protective sleeve. Finally, the adhesive patch is used to bond the protective sleeve to the ground, providing a wrap-around protection for the external power cord, preventing workers from stepping on it and causing damage or deformation to the external power cord, thus extending the service life of the external power cord.

[0013] 2. This utility model, through the setting of a limiting rod, a return spring, a protective sleeve, a limiting block, a limiting spring, and a limiting latch, allows staff inside the building to press down the limiting latch when they need to use the main body of the device. The limiting latch releases the limiting sleeve from its locked state, and the protective sleeve, through the elastic force of the return spring, presses against the limiting block, causing the protective sleeve to slide along the limiting rod, exposing the adapter at the top of the main body of the device for insertion and use. When not in use, the limiting latch is pressed down again, sliding the protective sleeve closed. At this time, the limiting latch is pushed out by the elastic force of the limiting spring and engages with the protective sleeve for fixation. The protective sleeve prevents dust from entering the adapter and also prevents water from entering and causing a short circuit. Attached Figure Description

A protective sleeve 3 is installed on the outer wall of the external power cord 2. A slot 4 is provided on the side wall of the protective sleeve 3. A connecting rod 5 is installed on the side of the protective sleeve 3 away from the slot 4. An adhesive patch 6 is installed on the bottom of the protective sleeve 3. The protective sleeve 3 is sleeved with the external power cord 2 and is elastically designed. The slot 4 engages with the connecting rod 5, and the protective sleeve 3 is bonded to the adhesive patch 6. Through the external power cord 2, the protective sleeve 3 is sleeved with the external power cord 2. Then, according to the length of the external power cord 2, the connecting rod 5 is inserted into the slot 4 to extend the protective sleeve 3. Finally, the adhesive patch 6 is used to bond the protective sleeve 3 to the ground, providing a wrapping protection for the external power cord 2, preventing workers from stepping on it and causing damage or deformation to the external power cord 2, thus extending the service life of the external power cord 2.

[0022] Please see Figure 1-4A multi-interface power adapter for building applications includes a limit rod 7 mounted on the side wall of the main body 1, a return spring 8 mounted on the outer wall of the limit rod 7, a protective sleeve 9 mounted on the top of the main body 1, a limit block 10 mounted on the inner side wall of the protective sleeve 9, a limit spring 11 mounted on the inner wall of the main body 1, and a limit lever 12 mounted on the outer wall of the limit spring 11.
