Description

Technical Field

[0001] This utility model relates to the field of fixed bracket technology, and in particular to a power supply housing fixing structure. Background Technology

[0002] The power supply casing is an important component of power supply equipment. It is mainly used to protect the internal circuits and components, while providing necessary heat dissipation and shielding functions. It can prevent the internal circuits and components from physical damage, such as impact and squeezing, as well as prevent dust, moisture and other contaminants from entering the power supply, keeping the internal environment clean and dry.

[0003] In the existing technology, the power supply casing is fixed by screws. The screw assembly requires tightening each screw individually, which is time-consuming. The threads may also be affected by environmental factors, which can accelerate their aging process and make it inconvenient for the power supply casing to be disassembled and maintained later. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of the existing power supply casing fixing structure, which basically uses screws to complete the assembly of the casing. Screw assembly requires tightening each screw one by one, which is time-consuming. The threads may also be affected by environmental factors, which accelerates their aging process and makes it inconvenient for the later disassembly and maintenance of the power supply casing. Therefore, a power supply casing fixing structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a power supply housing fixing structure, including a top cover, a fixing device provided on one side of the top cover, the fixing device including a hinge and two buckles, one side of the hinge and two buckles being fixedly connected to the top cover, a power supply housing being fixedly connected to one side of the hinge, two buckle grooves being opened on the inner side of the power supply housing, the inside of the buckle grooves being adapted to the buckles, a limiting plate being fixedly connected to both sides of the power supply housing, a limiting frame being slidably connected to the outside of the limiting plate, a guide plate being fixedly connected to one side of the limiting frame, a movable plate being fixedly connected to both ends of the guide plate, two telescopic rods being fixedly connected to one side of the movable plate, a square plate being fixedly connected to one end of the two telescopic rods, and one side of the two square plates being fixedly connected to the top cover.

[0006] The effect achieved by the above components is as follows: the moving plate moves to retract the output end of the telescopic rod, causing the guide plate to drive the limiting frame to move away from the limiting plate. After the limiting frame is completely away from the limiting plate, a pulling force is applied to the top cover in the direction away from the power supply housing, which can separate the buckle and the buckle groove, and make the top cover rotate around the hinge.

[0007] Preferably, the arc surface of the telescopic rod is fitted with a spring, and the two ends of the two springs are respectively fixedly connected to the square plate and the movable plate.

[0008] The aforementioned components achieve the following effects: the movement of the movable plate drives the output of the telescopic rod and the spring is stretched.

[0009] Preferably, a stop block is fixedly connected to one side of the movable plate, and the stop block is made of rubber.

[0010] The effect achieved by the above components is to fix the block to the moving plate.

[0011] Preferably, a bolt is threaded onto one side of the square plate, and one end of the bolt abuts against the abutment block.

[0012] The effect achieved by the above components is that the bolt rotates under force, causing it to move in position on the square plate.

[0013] Preferably, a rotating device is provided on one side of the upper cover. The rotating device includes a concave square rod, one side of which is fixedly connected to the upper cover, and two round rods are fixedly connected to the inner side of the concave square rod.

[0014] The effect achieved by the above components is that the round rod is fixed on the concave square rod.

[0015] Preferably, the circular rod has a rotating ring rotatably connected to its arc surface.

[0016] The effect achieved by the above components is that the rotating ring rotates on the round rod.

[0017] Preferably, handles are fixedly connected to the arc surfaces of the two rotating rings, and the cross-section of the handles is U-shaped.

[0018] The effect achieved by the above components is that the handle rotates around the rotating ring when subjected to force.

[0019] Preferably, the arc surface of the handle is fixedly connected with an anti-slip sleeve, which is made of rubber.

[0020] The effect achieved by the above components is to increase friction by preventing slippage.

[0021] Preferably, the handle has two rubber groove blocks that are interference-fitted to the arc surface, and the two rubber groove blocks are fixedly connected to the concave square rod on the side that is far apart from each other.

[0022] The effect achieved by the above components is that the rubber groove block limits the handle.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] In this utility model, by means of a fixing device, when it is necessary to disassemble and fix the power supply shell, the limiting frame is moved away from the limiting plate, eliminating the limitation on the top cover and the power supply shell. A pulling force is applied to the top cover to make the buckle disengage from the buckle groove. By means of a fixing device, the problem of traditional power supply shell fixing structure, which basically uses screws to complete the assembly of the shell, is solved. Screw assembly requires tightening each one, which is time-consuming. The threads may also be affected by environmental factors, which accelerates their aging process and makes it inconvenient for the later disassembly and maintenance of the power supply shell.

[0025] In this invention, by means of a rotating device, when it is necessary to move the power supply casing, the anti-slip sleeve is pulled, and a continuous pulling force is transmitted to the handle, which can move the power supply casing. By means of a rotating device, the problem of the traditional fixed structure of the power supply casing, which has few external force points, is solved, making it inconvenient to move the power supply casing.

[0031] Reference Figure 1 and Figure 3 As shown, this utility model provides a technical solution: a power supply housing fixing structure, including an upper cover 1, a fixing device 2 on one side of the upper cover 1, and a rotating device 3 on one side of the upper cover 1.

[0032] The following section will describe in detail the specific setup and function of its fixing device 2 and rotating device 3.

[0033] Reference Figure 2As shown in this embodiment: the fixing device 2 includes a hinge 201 and two buckles 204. One side of the hinge 201 and the two buckles 204 are fixedly connected to the upper cover 1. One side of the hinge 201 is fixedly connected to a power housing 202. Two buckle slots 203 are opened on the inner side of the power housing 202. The inside of the buckle slots 203 is adapted to the buckles 204. Limiting plates 205 are fixedly connected to both sides of the power housing 202. Limiting frames 206 are slidably connected to the outside of the limiting plates 205. One side of the limiting frame 206 is fixedly connected to a guide plate 207. The two ends of the guide plate 207 are fixedly connected to moving plates 211. Two telescopic rods 209 are fixedly connected to one side of the moving plate 211. One end of the two telescopic rods 209 is fixedly connected to a square plate 208. One side of the two square plates 208 is fixedly connected to the upper cover 1. The movement of the movable plate 211 causes the output end of the telescopic rod 209 to retract, which in turn causes the guide plate 207 to move the limiting frame 206 away from the limiting plate 205. After the limiting frame 206 is completely away from the limiting plate 205, a pulling force is applied to the upper cover 1 in the direction away from the power supply housing 202, which separates the buckle 204 and the buckle groove 203, allowing the upper cover 1 to rotate around the hinge 201. A spring 210 is fitted onto the arc surface of the telescopic rod 209, and the two ends of the two springs 210 are fixedly connected to the square plate 208 and the movable plate 211, respectively. This achieves the effect of the movable plate 211 moving to drive the output end of the telescopic rod 209 and the springs 210 stretching. A rubber abutment 213 is fixedly connected to one side of the movable plate 211, achieving the effect of the abutment 213 being fixed to the movable plate 211. A bolt 212 is threadedly connected to one side of the square plate 208, with one end of the bolt 212 abutting against the abutment 213. This achieves the effect of the bolt 212 rotating under force and moving its position on the square plate 208.

[0034] Reference Figure 4 As shown, in this embodiment: the rotating device 3 includes a concave square rod 31, one side of which is fixedly connected to the upper cover 1, and two round rods 32 are fixedly connected to the inner side of the concave square rod 31. This achieves the effect of fixing the round rods 32 to the concave square rod 31. A rotating ring 33 is rotatably connected to the arc surface of the round rod 32. This achieves the effect of rotating the ring 33 on the round rod 32. A handle 34 is fixedly connected to the arc surface of the two rotating rings 33, and the handle 34 has a "U" shaped cross-section. This achieves the effect of rotating the handle 34 around the rotating ring 33 when subjected to force. An anti-slip sleeve 35, made of rubber, is fixedly connected to the arc surface of the handle 34. This achieves the effect of increasing friction with the anti-slip sleeve 35. Two rubber groove blocks 36 are interference-fitted to the arc surface of the handle 34, and the side of the two rubber groove blocks 36 that is far apart from each other is fixedly connected to the concave square rod 31. This achieves the effect of limiting the position of the handle 34 with the rubber groove blocks 36.

[0035] Working principle: When the power supply casing needs to be disassembled and fixed via the fixing device 2, the operator first rotates the bolt 212 to adjust its position on the square plate 208, so that it does not abut against the stop block 213, thus eliminating the limitation on the moving plate 211. The movement of the moving plate 211 causes the output end of the telescopic rod 209 to retract and the spring 210 to contract. At the same time, the guide plate 207 drives the limiting frame 206 to move away from the limiting plate 205. After the limiting frame 206 is completely away from the limiting plate 205, it applies pressure to the upper cover 1 in a direction away from the power supply casing 202. The pulling force can separate the buckle 204 and the buckle groove 203, allowing the top cover 1 to rotate around the hinge 201, thereby completing the disassembly between the top cover 1 and the power supply housing 202. Repeating the above reverse steps can complete the fixation between the top cover 1 and the power supply housing 202. The fixing device 2 solves the problem of the traditional power supply housing fixing structure, which basically uses screws to complete the assembly of the housing. Screw assembly requires tightening each screw individually, which is time-consuming. The threads may also be affected by environmental factors, accelerating their aging process and making it inconvenient for the later disassembly and maintenance of the power supply housing.

[0036] When the power supply casing needs to be moved, the operator first pulls the anti-slip sleeve 35. The anti-slip sleeve 35 is pulled and the handle 34 moves away from the rubber groove block 36. During the movement, the handle 34 rotates around the rotating ring 33. The rotating ring 33 rotates on the round rod 32. The continuously applied pulling force can move the power supply casing. The rotating device 3 solves the problem that the traditional fixed structure of the power supply casing has few external force points, which makes it inconvenient to move the power supply casing.
