Description

Technical Field

[0001] The utility model relates to the technical field of industrial power supplies, in particular to an industrial power supply with a modular circuit structure. Background Art

[0002] Industrial power supplies with modular circuit structures are called modular power supplies. These power supplies can be mounted directly on printed circuit boards and provide stable power for various ASICs, digital signal processors, and microprocessors. These power supplies, with their high integration, high performance ratio, low loss, and high efficiency, are widely used in a variety of fields, including industrial automation control, communications equipment, and medical devices.

[0003] In the prior art, industrial power supplies with modular circuit structures are usually equipped with multiple supporting operating modules to ensure their continuous and uninterrupted operation. These modules are designed with redundancy and backup requirements in mind, so that when an operating module fails or fails, other normal operating modules can quickly replace it and continue to perform their functions, thereby ensuring the stable operation of the entire power supply system. However, during actual operation, when an operating module is damaged or fails, staff often need to perform a power-off operation before repairing or replacing the module. This process is not only time-consuming, but also affects the normal operation of the entire production line, causing unnecessary economic losses to the enterprise. At the same time, due to the special nature of industrial power supplies, the power-off operation also involves safety risks and requires professional technicians to operate, which increases the difficulty and complexity of maintenance. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an industrial power supply with a modular circuit structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an industrial power supply with a modular circuit structure, comprising a power supply housing and a power supply supporting module, wherein one end of the power supply supporting module is provided with a heat dissipation fan, and the other end of the power supply supporting module is provided with a fixed side groove, the top linear array of the power supply housing is provided with an assembly groove, one side of the assembly groove is provided with a heat dissipation rectangular groove, the inner wall of the assembly groove is provided with a mounting groove, and the mounting groove is fixed with a running frame, one side of the inner wall of the running frame is provided with an inclined groove, and the inner wall of the inclined groove is slidably connected with a side auxiliary short column, one end of the side auxiliary short column is fixed with a rotating hanging hook, one side of the rotating hanging hook is fixed with a rail groove part, one side of the rail groove part is fixed with a compressed L arm, the inner wall of the rail groove part is slidably connected to the surface of the running frame, one end of the rail groove part is fixed with an auxiliary spring, the auxiliary spring, the bottom of the fixed column is fixed to the surface of the running frame, the bottom end of the running frame is rotatably connected with a limit rod, and one end of the limit rod is slidably connected to the inner wall of the rail groove part.

[0006] Preferably, a bottom supporting circular groove is provided at the bottom of the inner wall of the assembly groove, a limiting ring groove is provided at the top of the inner wall of the bottom supporting circular groove, a friction ring is slidably connected to the inner wall of the limiting ring groove, a bottom pad is fixed to the circumference of the inner wall of the friction ring, a buffer spring is fixed to the bottom of the bottom pad, and the bottom end of the buffer spring is fixed to the bottom of the inner wall of the bottom supporting circular groove. In the prior art, after the power supply supporting module is installed in the power supply casing, it will shake up and down during transportation and handling. This shaking will not only cause the power supply supporting module itself to be impacted and vibrated, but also cause its bottom to collide continuously with the inner wall of the power supply casing. Since other precision components are usually installed inside the power supply casing, these collisions will cause damage to these components, thereby affecting the normal operation of the entire power supply system. More seriously, long-term collisions and impacts will cause the power supply supporting module to Modules and other components become loose, deformed or damaged, thereby reducing the service life of the equipment, which not only increases maintenance costs and replacement frequency, but also affects the reliability and stability of the equipment, causing unnecessary economic losses and safety hazards to the enterprise. To address such problems, the utility model solves this problem by installing a base pad. When up and down shaking occurs during transportation and handling, the power supply supporting module presses the base pad to move downward during downward movement, compresses the buffer spring, and converts vibration and impact into elastic potential energy. When the buffer spring releases the elastic potential energy, the friction ring circumference and the inner wall of the limiting ring groove have a high friction coefficient, so that the contact surface between the two has a large friction force when sliding, thereby converting the elastic potential energy into internal energy, reducing the impact of vibration and impact, and achieving the effect of increasing the service life of the equipment.

[0007] Preferably, a fixed shaft rod is fixed on the top of the power supply housing, a spring sheet is fixed on the thin-diameter circumference of the fixed shaft rod, a dynamic shaft ring is rotatably connected to the thin-diameter circumference of the fixed shaft rod, an arc groove is provided on the inner wall of the dynamic shaft ring, and a protective cover is fixed on the circumference of the dynamic shaft ring. In the prior art, during the daily maintenance and care of industrial power supplies, it is often necessary to disassemble and assemble the power supply supporting module for inspection or replacement. However, in this process, the design of the protective cover often does not take into account the importance of the positioning component. Due to the lack of an effective positioning mechanism, the protective cover is easily affected by vibration or other external factors during the disassembly and assembly process, causing it to flip over and close by itself. This situation not only increases the difficulty of the operator's work, but also reduces work efficiency, because each time the protective cover is disassembled, the operator is easily affected by vibration or other external factors ... After the cover flips over and closes by itself, it needs to be reopened and adjusted in position to ensure that subsequent disassembly and assembly work can be carried out normally. This not only wastes valuable time, but also affects the normal operation of the entire production line. In addition, the self-flipping and closing of the protective cover also poses a threat to the safety of the operator, because during the disassembly and assembly process, if the protective cover suddenly closes, it may pinch fingers or other parts of the body, increasing the risk of work-related accidents. To solve this problem, the utility model adopts the method of installing a spring sheet to solve it. When the staff rotates to fully open the protective cover and the arc groove of the dynamic shaft ring reaches the position of the spring sheet, the spring sheet releases its elastic potential energy and embeds into the arc groove, so that the protective cover is temporarily fixed, and feedback is given to the staff at the same time, so as to achieve the effect of improving user experience.

[0008] Preferably, vertical ladder grooves are provided on both sides of the inner wall of the assembly groove, and a limiting slide member is slidably connected to the inner wall of the vertical ladder groove. One side of the limiting slide member is fixed to the side of the power supply supporting module. By limiting the cooperation between the slide member and the vertical ladder groove, the position of the power supply supporting module during installation and removal is limited to prevent scratches and prevent left and right shaking, thereby improving the stability of the equipment.

[0009] Preferably, a protective net is fixed to the inner wall of the heat dissipation rectangular groove to prevent the user from getting too close to the heat dissipation area, thereby preventing the user from being scalded and improving the user experience.

[0010] Preferably, a hand groove is provided at one end of the protective cover to facilitate user use and improve user experience.

[0011] Preferably, both sides of the power supply housing are provided with lifting slots to facilitate transportation and improve user experience.

[0012] Beneficial effects:

[0013] 1. In the prior art, industrial power supplies with modular circuit structures are usually equipped with multiple supporting operation modules to ensure that they can operate continuously and uninterruptedly. These modules are designed with redundancy and backup requirements in mind, so that when a certain operation module fails or fails, other normal operation modules can quickly replace it and continue to perform their functions, thereby ensuring the stable operation of the entire power supply system. However, in actual operation, when a certain operation module is damaged or fails, the staff often needs to cut off the power before repairing or replacing the module. This process is not only time-consuming, but also affects the normal operation of the entire production line, causing unnecessary economic losses to the enterprise. At the same time, due to the special nature of industrial power supplies, the power-off operation also involves safety risks and requires professional technicians to operate, which increases the difficulty and complexity of maintenance. In response to such problems, the utility model solves them by installing an operation framework, which enables the staff to install the power supply supporting modules. When the bottom of the power supply module contacts the compressed L arm, the compressed L arm is pressed downward to move the rail groove part downward, and one end of the slave limit rod slides along the left side of the rail groove part with the downward movement, and finally enters the angle groove above the rail groove part, so that the slave limit rod hangs on the rail groove part, so that the rail groove part is temporarily fixed. At the same time, as the rail groove part moves downward, the rotary hanging hook is pulled. Due to the coordination of the inclined groove and the side auxiliary short column, the rotary hanging hook rotates inward to hook the fixed side groove of the power supply module to fix it. When the staff needs to disassemble, they press the power supply module downward and press the compressed L arm downward again to make the slave limit rod slide out of the left groove of the rail groove part. The auxiliary spring releases the elastic potential energy to move the rail groove part upward, and the rotary hanging hook rotates outward to disengage from the fixed side groove, which is convenient for the staff to disassemble and assemble. Even during the production process, the staff can promptly remove the faulty power supply module and can replace it quickly without stopping the machine and affecting the production fluency, thereby achieving the effect of improving production efficiency.

[0014] 2. In the prior art, after the power supply module is installed in the power supply housing, it will shake up and down during transportation and handling. This shaking will not only cause the power supply module itself to be impacted and vibrated, but also cause its bottom to collide with the inner wall of the power supply housing. Since other precision components are usually installed inside the power supply housing, these collisions will damage these components, thereby affecting the normal operation of the entire power supply system. More seriously, long-term collisions and impacts will cause the power supply module and other components to become loose, deformed or damaged, thereby reducing the service life of the equipment. This will not only increase maintenance costs and replacement frequency, but also affect the equipment. Reliability and stability bring unnecessary economic losses and safety hazards to enterprises. To solve this problem, the utility model adopts the method of installing a bottom pad to solve it. When up and down shaking occurs during transportation and handling, the power supply supporting module presses the bottom pad to move downward during the downward movement, compresses the buffer spring, and converts vibration and impact into elastic potential energy. When the buffer spring releases the elastic potential energy, the circumferential surface of the friction ring and the inner wall of the limiting ring groove have a high friction coefficient, so that there is a large friction force on the contact surface between the two when sliding, thereby converting the elastic potential energy into internal energy, reducing the impact of vibration and impact, and achieving the effect of increasing the service life of the equipment.

[0015] 3. In the prior art, during the routine maintenance and servicing of industrial power supplies, it is often necessary to disassemble and assemble power supply supporting modules for inspection or replacement. However, in this process, the design of the protective cover often does not take into account the importance of the positioning component. Due to the lack of an effective positioning mechanism, the protective cover is easily affected by vibration or other external factors during the disassembly and assembly process, causing it to flip and close automatically. This situation not only increases the difficulty of the operator's work, but also reduces work efficiency. Because each time the protective cover flips and closes automatically, it needs to be reopened and adjusted to ensure that subsequent disassembly and assembly work can proceed normally. This not only wastes valuable time but also affects the normal operation of the entire production line. In addition, the automatic flipping and closing of the protective cover also poses a threat to the safety of the operator. Because during the disassembly and assembly process, if the protective cover suddenly closes, it may pinch fingers or other body parts, increasing the risk of work-related accidents. To address this problem, the present invention adopts a method of installing a spring leaf. When the operator rotates the protective cover to fully open and the arc groove of the movable shaft ring reaches the position of the spring leaf, the spring leaf releases its elastic potential energy and embeds into the arc groove, temporarily fixing the protective cover. At the same time, it provides feedback to the operator, achieving the effect of improving user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0029] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment:

[0031] Reference Figure 1-10 An industrial power supply with a modular circuit structure includes a power supply housing 1 and a power supply supporting module 101. A cooling fan 102 is provided at one end of the power supply supporting module 101, and a fixed side groove 103 is provided at the other end of the power supply supporting module 101. An assembly groove 2 is provided in a linear array on the top of the power supply housing 1. A heat dissipation rectangular groove 202 is provided on one side of the assembly groove 2. An installation groove 201 is provided on the inner wall of the assembly groove 2. A running frame 203 is fixed to the installation groove 201. A ramp groove 204 is provided on one side of the inner wall of the running frame 203. A side auxiliary short column 205 is slidably connected to the inner wall of the ramp groove 204. A rotating hook 2011 is fixed to one end of the side auxiliary short column 205, and a rail groove part 207 is fixed to one side of the rotating hook 2011. A compressed L arm 206 is fixed to one side of the rail groove part 207. The inner wall of the rail groove part 207 is slidingly connected to the surface of the running frame 203. An auxiliary spring 208 is fixed to one end of the rail groove part 207, and a fixed column 209 is fixed to one end of the auxiliary spring 208. The bottom of the fixed column 209 is fixed to the surface of the running frame 203. The bottom end of the running frame 203 is rotatably connected to a slave limit rod 2010, and one end of the slave limit rod 2010 is slidingly connected to the inner wall of the rail groove part 207. A bottom supporting circular groove 3 is provided at the bottom of the inner wall of the assembly groove 2, and a limiting ring groove 301 is provided at the top of the inner wall of the bottom supporting circular groove 3. A friction ring 304 is slidably connected to the inner wall of the limiting ring groove 301, and a bottom pad 303 is fixed to the inner wall circumference of the friction ring 304. A buffer spring 302 is fixed to the bottom of the bottom pad 303, and the bottom end of the buffer spring 302 is fixed to the bottom of the inner wall of the bottom supporting circular groove 3. After the power supply supporting module 101 is installed in the power supply casing 1, it will shake up and down during transportation and handling. This shaking will not only cause the power supply supporting module 101 itself to be impacted and vibrated, but also cause its bottom to collide with the inner wall of the power supply casing 1 continuously. Since other precision components are usually installed inside the power supply casing 1, these collisions will cause damage to these components, thereby affecting the normal operation of the entire power supply system. More seriously, long-term collisions and impacts will cause the power supply supporting module 101 to The set module 101 and other components become loose, deformed or damaged, thereby reducing the service life of the equipment, which will not only increase the maintenance cost and replacement frequency, but also affect the reliability and stability of the equipment, causing unnecessary economic losses and safety hazards to the enterprise. The problem is solved by installing a base pad 303. When the power supply supporting module 101 shakes up and down during transportation and handling, the base pad 303 is pressed downward during the downward movement of the power supply supporting module 101 to compress the buffer spring 302, and convert vibration and impact into elastic potential energy. When the buffer spring 302 releases the elastic potential energy, the circumference of the friction ring 304 and the inner wall of the limiting ring groove 301 have a high friction coefficient, so that there is a large friction force on the contact surface between the two when sliding, thereby converting the elastic potential energy into internal energy, reducing the impact of vibration and impact, and achieving the effect of increasing the service life of the equipment.

[0032] A fixed shaft rod 4 is fixed on the top of the power supply housing 1, and a spring sheet 401 is fixed on the thin-diameter circumference of the fixed shaft rod 4. The thin-diameter circumference of the fixed shaft rod 4 is rotatably connected to a dynamic shaft ring 402. An arc groove is provided on the inner wall of the dynamic shaft ring 402, and a protective cover 403 is fixed on the circumference of the dynamic shaft ring 402. During the daily maintenance and care of the industrial power supply, it is often necessary to disassemble and assemble the power supply supporting module 101 for inspection or replacement. However, in this process, the design of the protective cover 403 often does not take into account the importance of the positioning component. Due to the lack of an effective positioning mechanism, the protective cover 403 is easily affected by vibration or other external factors during the disassembly and assembly process, causing it to flip over and close by itself. This situation not only increases the difficulty of the operator's work, but also reduces work efficiency, because each time the protective cover 40 3 After automatically flipping and closing, it is necessary to reopen and adjust the position to ensure that subsequent disassembly and assembly work can be carried out normally. This not only wastes valuable time, but also affects the normal operation of the entire production line. In addition, the automatic flipping and closing of the protective cover 403 also poses a threat to the safety of the operator, because during the disassembly and assembly process, if the protective cover 403 suddenly closes, it will pinch fingers or other body parts, increasing the risk of work-related accidents. This is solved by installing a spring piece 401. When the worker rotates to fully open the protective cover 403 and the arc groove of the movable shaft ring 402 reaches the position of the spring piece 401, the spring piece 401 releases its elastic potential energy and embeds into the arc groove, temporarily fixing the protective cover 403 and giving feedback to the worker at the same time, thereby improving the user experience. Both sides of the inner wall of the assembly slot 2 are provided with vertical ladder slots 5, and the inner wall of the vertical ladder slot 5 is slidably connected with a limiting slide member 501, and one side of the limiting slide member 501 is fixed to the side of the power supply supporting module 101. By limiting the slide member 501 and the vertical ladder slot 5, the position of the power supply supporting module 101 during installation and removal is limited to prevent scratches and prevent left and right shaking, thereby improving the stability of the equipment. A protective net 6 is fixed to the inner wall of the heat dissipation circular slot 202 to prevent users from getting too close to the heat dissipation area, prevent users from being scalded, and improve user experience. A hand groove 404 is provided at one end of the protective cover 403 to facilitate user use and improve user experience. Lifting slots 7 are provided on both sides of the power supply housing 1 to facilitate transportation and improve user experience.

[0033] The working principle of the present invention is as follows: when the staff installs the power supply supporting module 101, the power supply supporting module 101 is slid into the assembly slot 2. When the bottom of the power supply supporting module 101 contacts the pressure L arm 206, the pressure L arm 206 is pressed downward to move the track groove part 207 downward. As the slave limit rod 2010 moves downward, it slides along the left side of the track groove part 207 and finally enters the angle groove above the track groove part 207, so that the slave limit rod 2010 hangs the track groove part 207, making the track groove part 207 temporarily fixed. At the same time, as the track groove part 207 moves downward, the rotary hook 2011 is pulled. Due to the contact between the inclined groove 204 and the side auxiliary short With the help of column 205, the hanging hook 2011 rotates inward to hook the fixed side groove 103 of the power supply supporting module 101 to fix it. When the staff needs to disassemble it, they press the power supply supporting module 101 downward and press the compressed L arm 206 downward again to make the limit rod 2010 slide out of the left groove of the track groove part 207. The auxiliary spring 208 releases the elastic potential energy to move the track groove part 207 upward, and the hanging hook 2011 rotates outward to disengage from the fixed side groove 103, which is convenient for the staff to disassemble and assemble. Even during the production process, the staff can remove the faulty power supply supporting module 101 in time and replace it quickly without stopping the machine and affecting the smoothness of production.

Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
