Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a transformer frame with a built-in turbulence duct, including a housing 100, an air vent 300 on the inner wall of the housing 100, an mounting plate 400 fixedly connected to the outer wall of the housing 100, a groove 500 on the inner wall of the mounting plate 400, and also includes a fixing mechanism 200, which is snapped into the mounting plate 400. The fixing mechanism 200 includes a connecting block 201, a bolt 202 fixedly connected to the outer wall of the bottom end of the connecting block 201, a moving block 203 slidably connected to the inner wall of the connecting block 201, a protrusion 206 slidably connected to the inner wall of the connecting block 201, an inclined block 204 fixedly connected to the outer wall of the protrusion 206, and a locking component provided on the outer wall of the connecting block 201.

[0018] The above-mentioned solution is as follows: the housing 100 is the main body of the transformer frame, which is existing technology; the air vent 300 is a turbulent air duct; the transformer coil can be wound around both ends of the housing 100; a heat dissipation vent is opened in the middle of the housing 100; and the inner wall of the air vent 300 is provided with spirally distributed protruding ridges as a turbulent part. The turbulent part can increase the heat exchange area of ​​the air duct, making the airflow in the air duct turbulent, thereby improving the heat exchange efficiency; the fixing mechanism 200 can be used to easily install the housing 100 on the mounting base of the electrical equipment, and it is convenient for operators to disassemble it; in the fixing mechanism 200, the bolt 202 and the connecting block 201 are integrated; the bolt 202 can be screwed and fixed in the bolt hole of the mounting base of the electrical equipment; the mounting plate 400 below the housing 100 can be snapped onto the outside of the connecting block 201 to complete the fixation.

[0019] like Figures 2 to 4 As shown, there are two sets of inclined blocks 204, which are elastically connected by a connecting spring 205. The connecting block 201 is in contact with the inner wall of the mounting plate 400. The inner wall of the moving block 203 is in contact with the outer wall of the inclined block 204, and the protrusion 206 is engaged with the groove 500. The two ends of the connecting spring 205 are fixedly connected to the outer walls of the two sets of inclined blocks 204 respectively, and the inclined blocks 204 are slidably connected to the inner wall of the connecting block 201.

[0020] Using the above scheme: The inner wall of the movable block 203 is always in contact with the inclined surface of the inclined block 204. Due to the elastic force of the connecting spring 205, the two sets of inclined blocks 204 are normally located on both sides of the inner wall of the connecting block 201, and the movable block 203 is in contact with the top of the inclined surface. The inclined block 204 drives the protrusion 206 to be in the pop-out state. When the operator manually presses down the movable block 203, its inner wall will move down along the inclined surface of the inclined block 204, and drive the inclined block 204 to move. Since the inclined block 204 is slidably connected to the inner wall of the connecting block 201, it can only move laterally, which will drive the two sets of inclined blocks 204 and protrusion 206 to move synchronously towards the middle, compressing the connecting spring 205; the protrusion After 206 moves into the inner wall of the connecting block 201, the mounting plate 400 can be inserted into the connecting block 201. The connecting spring 205 resets and drives the inclined block 204 and the protrusion 206 to move to both sides, so that the protrusion 206 engages with the groove 500 on the inner wall of the mounting plate 400, thus completing the fixation of the housing 100. When disassembling the housing 100, the moving block 203 is pressed down to move the protrusion 206 until it is no longer in contact with the groove 500, so that it can be easily and quickly removed. The fixing mechanism 200 is set up so that the bolt 202 is pre-connected during the first installation, and subsequent disassembly and installation can be completed by pressing the moving block 203, which is simple and convenient to operate.

[0021] like Figure 5 As shown, the locking assembly includes a rotating block 211, with a slanted groove 212 on the outer wall of the bottom end of the rotating block 211. A fixing block 213 is fixedly connected to the outer wall of the connecting block 201. A wedge block 215 is elastically connected to the inner wall of the fixing block 213 via a reset spring 214. A slide rod 216 is slidably connected to the inner wall of the fixing block 213. A square groove 217 is provided on the outer wall of the moving block 203.

[0022] Using the above scheme: when the moving block 203 is pressed down, the protrusion 206 and the inclined block 204 move towards the middle, but under the elastic force of the connecting spring 205, they tend to return to their original positions on both sides. The position of the moving block 203 can be fixed by the locking component, thereby fixing the position of the inclined block 204 and the protrusion 206. The square groove 217 on the outer wall of the moving block 203 is provided with two sets, upper and lower, which can be engaged with the wedge block 215 to fix the moving block 203. The arc surface of the wedge block 215 always faces upward, and under the elastic force of the return spring 214, it remains in the popped-out state.

[0023] like Figure 5As shown, the rotating block 211 is rotatably connected to the outer wall of the connecting block 201, one end of the sliding rod 216 is fixedly connected to the outer wall of the wedge block 215, and the other end of the sliding rod 216 is slidably connected to the inner wall of the inclined groove 212. The wedge block 215 is engaged with the square groove 217. One end of the return spring 214 is fixedly connected to the outer wall of the wedge block 215, and the other end of the return spring 214 is fixedly connected to the inner wall of the fixed block 213. The wedge block 215 is slidably connected in the inner wall of the fixed block 213.

[0024] Using the above scheme: Under normal conditions, the wedge block 215 and the slide rod 216 are in a fixed position, and the slide rod 216 is in contact with one end of the inner wall of the inclined groove 212. When the moving block 203 is pressed down, the lower square groove 217 squeezes the arc surface of the wedge block 215, causing it to move into the inner wall of the fixed block 213. When the moving block 203 moves down to the position of the upper square groove 217 corresponding to the wedge block 215, the wedge block 215 pops out due to the elastic force of the return spring 214 and gets stuck in the square groove 217, which can limit the moving block 203, preventing it from moving upward due to the influence of the inclined block 204, thereby locking the position of the inclined block 204 and the protrusion 206, so that they are completely in the inner wall of the connecting block 201; due to the installation The plate 400 is fixed to the housing 100 by multiple sets of fixing mechanisms 200. When all fixing mechanisms 200 are in this state, the housing 100 can be installed or disassembled. The operator can rotate the rotating block 211, and the inclined groove 212 will squeeze the sliding rod 216. Since the sliding rod 216 and the wedge block 215 can only move laterally, under the action of the inclined groove 212, the sliding rods 216 on both sides will drive the wedge block 215 to move to both sides at the same time. After the wedge block 215 disengages from the square groove 217, the limiting position of the moving block 203 is released. The elastic force of the connecting spring 205 will cause the inclined block 204 to move to both sides. The inclined block 204 squeezes the moving block 203 to move upward and reset, and the fixing mechanism 200 returns to the initial state.

[0025] Working principle and usage process of this utility model: The air vent 300 in the middle of the housing 100 is a turbulence part with spiral protrusions. By increasing the airflow contact area and turbulence intensity, it breaks the laminar boundary layer, allowing the cold air to fully exchange heat with the inner wall of the housing 100. The spiral air duct extends the airflow path, and together with the transformer's operation, it forms a directional heat dissipation cycle through natural convection or forced air cooling.

[0026] When installing the housing 100, the bolt 202 can be rotated and fixed in the equipment mounting base. Then, the moving block 203 is pressed down, and the inclined block 204 is squeezed inward, which drives the protrusion 206 to retract into the inner wall of the connecting block 201. At the same time, the upper square groove 217 moves down to the position of the wedge block 215. The spring force of the return spring 214 makes the wedge block 215 snap into the square groove 217, locking the moving block 203, thereby automatically fixing the position of the protrusion 206.

[0027] After all the fixing mechanisms 200 are installed and the protrusion 206 is fixed, the through groove on the mounting plate 400 can be aligned with the position of the connecting block 201 and inserted into the connecting block 201. When the mounting plate 400 contacts the equipment mounting base, the rotating block 211 is rotated manually. The inclined groove 212 squeezes the sliding rod 216, causing the wedge block 215 to move and disengage from the square groove 217. The connecting spring 205 pushes the inclined block 204 to reset. The inclined surface of the inclined block 204 pushes the moving block 203 to move upward, causing the protrusion 206 to pop out and engage with the groove 500, thus completing the connection and fixing of the housing 100 with the fixing mechanism 200 and the equipment mounting base.

[0028] When the housing 100 needs to be disassembled for maintenance, the disassembly and installation process can be carried out by repeatedly pressing the moving block 203 to move the protrusion 206 into the inner wall of the connecting block 201, which can be done conveniently and quickly without the need for other tools. The position of the protrusion 206 is locked by the locking component, which allows the operator to operate by one person. The structure is simple and the operation is convenient.
