Description

Technical Field

[0001] This utility model relates to the field of power module technology, specifically to a wide voltage adaptive power module for video all-in-one machines. Background Technology

[0002] With the rapid development of video surveillance technology, video all-in-one machines have been widely used in many fields such as security, transportation, and industrial monitoring. In different application scenarios, the power supply environment faced by video all-in-one machines varies significantly.

[0003] In urban traffic monitoring, the equipment is usually powered by mains electricity. However, due to changes in grid load and line losses, the voltage may fluctuate within a certain range. At this time, a voltage-adaptive power module is required. Then, it is connected to the video all-in-one machine through a connecting cable. On some mobile devices or video all-in-one machines that vibrate during operation, the connectors of these connecting cables may become loose due to vibration, resulting in voltage fluctuations and affecting the normal use of the video all-in-one machine. Utility Model Content

[0004] In view of the problems existing in the power modules of the current video all-in-one machine, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a wide voltage adaptive power supply module for video all-in-one machines, which solves the problem that the connectors of these connecting cables on some mobile devices or video all-in-one machines that vibrate during operation are usually loose due to vibration, resulting in voltage fluctuations and affecting the normal use of the video all-in-one machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wide-voltage adaptive power supply module for a video all-in-one machine includes a power supply module body. A fixing block is fixedly connected to one side of the power supply module body. Multiple sockets are provided on one side of the fixing block. A connector is inserted into each socket. An electric wire is fixedly connected to one end of each connector. Each connector is electrically connected to the power supply module body. Multiple cavities are provided inside the fixing block. Sliding grooves are provided at both ends of each cavity. Fixing mechanisms are provided inside the two sliding grooves. Each connector is fixed by a corresponding fixing mechanism. An adjustment mechanism is provided inside each cavity. Each fixing mechanism is matched with a corresponding adjustment mechanism.

[0007] Preferably, the fixing mechanism includes a fixing block and a plurality of insert blocks. A square hole is provided between each of the slide grooves and the insertion holes. Each insert block is slidably disposed inside the corresponding square hole. Each mounting block is slidably disposed inside the corresponding slide groove and is fixedly connected to one side of the corresponding insert block.

[0008] Preferably, the adjustment mechanism includes multiple rotating rods, multiple gears, multiple racks, multiple movable plates, and knobs. Each rotating rod is rotatably connected to the interior of a corresponding cavity. Each gear is fixedly sleeved on the wall of the corresponding rotating rod. Each movable plate is slidably disposed inside the interior of the corresponding cavity. Each rack is fixedly connected to one side of the corresponding movable plate and meshes with the corresponding gear. One end of each of the two rotating rods passes through one side of the corresponding cavity and is fixedly connected to the corresponding knob.

[0009] Preferably, both of the rotating rods have torsion springs fixedly sleeved on their walls.

[0010] Preferably, the outer surfaces of the two movable plates are respectively attached to the inner walls of the corresponding cavities.

[0011] Preferably, each connector has symmetrically provided slots on its sidewalls, and each slot is matched with a corresponding plug.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. In this utility model, rotating the knob drives the plug to insert into the connector slot, forming a double rigid lock. Combined with the pre-tightening force of the torsion spring, it can resist loosening caused by high-frequency vibration and ensure that the wide voltage adaptive power supply module can supply power stably.

[0013] 2. In this utility model, the torsion spring on the wall of the rotating rod undergoes elastic deformation when the knob is rotated, storing elastic potential energy. After locking, the torsion spring releases the preload and generates a reverse torque on the rotating rod, thereby allowing the two insert blocks to be reset after movement.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a wide voltage adaptive power supply module for video all-in-one machines.

[0019] This utility model provides, for example Figure 1-3 The wide voltage adaptive video all-in-one power module shown includes a power module body 1. A fixing block 2 is fixedly connected to one side of the power module body 1. Multiple sockets are opened on one side of the fixing block 2. A connector 3 is inserted into the interior of each socket. A wire 4 is fixedly connected to one end of each connector 3. Each connector 3 is electrically connected to the power module body 1. Multiple cavities are opened inside the fixing block 2. A sliding groove is opened at both ends of each cavity. A fixing mechanism is set inside each of the two sliding grooves. Each connector 3 is fixed by a corresponding fixing mechanism. An adjustment mechanism is set inside each cavity. Each fixing mechanism is matched with a corresponding adjustment mechanism.

[0020] like Figure 1-3 As shown, the fixing mechanism includes a fixing mounting block 5 and multiple insert blocks 6. A square hole is provided between each slide and the insertion hole. Each insert block 6 is slidably disposed inside the corresponding square hole. Each mounting block 5 is slidably disposed inside the corresponding slide and is fixedly connected to one side of the corresponding insert block 6. The adjusting mechanism includes multiple rotating rods 7, multiple gears 8, multiple racks 9, multiple moving plates 10 and knobs 11. Each rotating rod 7 is rotatably connected to the inside of the corresponding cavity. Each gear 8 is fixedly sleeved on the rod wall of the corresponding rotating rod 7. Each moving plate 10 is slidably disposed inside the corresponding cavity. Each rack 9 is fixedly connected to one side of the corresponding moving plate 10 and meshes with the corresponding gear 8. One end of each of the two rotating rods 7 passes through one side of the corresponding cavity and is fixedly connected to the corresponding knob 11. Each connector 3 has symmetrical slots on its side wall, and each slot matches the corresponding insert block 6.

[0021] Insert connector 3 into the socket of fixing block 2 to ensure electrical connection between connector and power module body 1. During this process, turn knob 11 to drive rotating rod 7 to rotate in cavity. Gear 8 on the rod wall rotates synchronously and meshes with rack 9 on one side of moving plate 10, driving moving plate 10 to slide horizontally along cavity. When moving plate 10 slides, it drives mounting block 5 to move along slide groove and insert it into slot on side wall of connector 3 to form rigid locking structure, thereby avoiding voltage fluctuations caused by loose connector.

[0022] like Figure 2 As shown, torsion springs 12 are fixedly sleeved on the walls of both rotating rods 7.

[0023] When the knob is turned, the torsion spring 12 on the wall of the rotating rod 7 undergoes elastic deformation and stores elastic potential energy. After locking, the torsion spring 12 releases the preload and generates a reverse torque on the rotating rod 7, so that the two inserts can be reset after moving.

[0024] like Figure 2-3 As shown, the outer surfaces of the two movable plates 10 are respectively attached to the inner walls of the corresponding cavities.

[0025] Because the outer surface of the movable plate 10 fits against the inner wall of the corresponding cavity, it can play a limiting role, preventing the rack 9 from separating from the corresponding gear 8.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
