Description

Technical Field

[0001] This utility model relates to the field of power protection device technology, and in particular to a device power protection device. Background Technology

[0002] A power protector is a device used to protect electronic equipment from power problems. It is widely used in home appliances, computer systems, communication equipment, industrial control systems and other fields, and is an important component to ensure electrical safety and equipment lifespan.

[0003] However, most of the existing power protectors on the market are not easy for staff to disassemble and install, making it difficult for staff to remove and repair them, and increasing the difficulty of operation for staff.

[0004] Therefore, those skilled in the art have provided a device power protector to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a power protector for equipment. The first reset spring in the mounting mechanism acts on the slide rod, which, in conjunction with the locking block and the upper end of the outer shell, and the metal block that is fixedly connected to the lower end of the outer shell, locks together. This allows the operator to pull the locking block to release the locking state between the locking block and the metal block, facilitating disassembly and installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A power protector for an equipment includes two housings, a mounting mechanism, and an actuating mechanism. The mounting mechanism is located at the rear end of each housing and includes a mounting block. The actuating mechanism is located inside each housing and includes a top block, a moving frame, a rotating rod, and a limiting block. A fixing frame is fixedly connected to the front end of the inner wall of each housing. A winding drum is fixedly connected to the upper end of the inner wall of the front end of the fixing frame. A second return spring is fixedly connected to the center inside the fixing frame. An induction coil is wound around the outer wall of the winding drum. A metal contact piece is fixedly connected to the middle of the lower end of the fixing frame.

[0008] The lower end of the induction coil passes through the fixed frame and is fixedly connected to the metal contact piece. Racks are fixedly connected to both sides of the outer wall of the front end of the movable frame. Gears are fixedly connected to both sides of the outer wall of the rotating rod. A push rod is fixedly connected to the middle of the outer wall of the rotating rod. An arc-extinguishing grid is fixedly connected to the rear end of the inner wall of the outer shell. The middle of the front end of the lower end of the arc-extinguishing grid is fixedly connected to the metal contact piece. A metal conductive sheet is fixedly connected to the lower end of the arc-extinguishing grid. A first connecting block is fixedly connected to the lower end of the inner wall of the outer shell. A bimetallic sheet is fixedly connected to the rear end of the upper end of the first connecting block.

[0009] Through the above technical solution, the induction coil wound on the winding drum in the action mechanism generates a strong magnetic field that attracts the top block to overcome the elastic force of the second reset spring, pushing the moving frame downwards. This forces the metal conductive plate away from the metal contact plate, disconnecting the circuit and preventing damage to the equipment due to excessive circuit current and reversed power polarity. The metal block fixedly connected to the lower end of the outer casing and the grounding wire fixedly connected to the lower end of the mounting block conduct the static electricity accumulated on the outer casing to the ground, preventing damage to the equipment due to static electricity. The bimetallic strip is heated by the surge current and deforms, causing the moving frame to move downwards. This, in conjunction with the moving frame, forces the metal conductive plate away from the metal contact plate, disconnecting the circuit and preventing damage to the equipment from the surge current.

[0010] Furthermore, the upper end of the mounting block is provided with sliding grooves on both sides, and a first return spring is fixedly connected to the top of the sliding groove. A sliding rod is fixedly connected to the lower end of the first return spring. A limiting block is fixedly connected to the upper end of the outer wall of the front end of the sliding rod. A locking block is fixedly connected to the rear end of the upper end of the outer shell. A metal block is fixedly connected to the rear end of the lower end of the outer shell. A grounding wire is fixedly connected to the middle of the lower end of the mounting block.

[0011] Through the above technical solution, the first reset spring in the installation mechanism acts on the slide rod, and the slide rod is fixedly connected to the limiting block. It is also connected to the upper end of the housing by the locking block and the lower end of the housing by the metal block. This allows the operator to pull the limiting block to release the locking state between the limiting block and the locking block, thus facilitating the operator to disassemble and install the device. It also makes it easier for the operator to disassemble the device and inspect the power protector.

[0012] Furthermore, the upper end of the second return spring is fixedly connected to the top block, the top block slides inside the winding drum, and the bimetallic strip is connected to the metal conductive strip through a wire;

[0013] Through the above technical solution, the induction coil wound on the winding drum generates a strong magnetic field that attracts the top block to overcome the elastic force of the second reset spring, pushing the moving frame downward. The bimetallic strip is connected to the metal conductive strip through a wire, connecting the circuit. When the metal conductive strip is moved away from the metal contact piece, the circuit can be broken.

[0014] Furthermore, a second connecting block is fixedly connected to the upper end of the induction coil, and the outer walls on both sides of the second connecting block are fixedly connected to the outer shell;

[0015] Through the above technical solution, the second connecting block, which is fixedly connected to the upper end of the induction coil and the second connecting block fixedly connected inside the housing, can be connected to the external device circuit.

[0016] Furthermore, the outer walls on both sides of the movable frame are slidably connected to the outer shell, and the limiting block is located between the metal contact piece and the movable frame and slides inside the outer shell;

[0017] Through the above technical solution, the movable frame is slidably connected to the inner wall of the outer shell, so that when the top block moves down, it can push the movable frame down. The limit block is pushed by the push rod fixedly connected to the middle of the rotating rod to move inside the outer shell, blocking the top of the movable frame to prevent the circuit from being disconnected. When the metal conductive sheet returns to its original position, the movable frame moves up.

[0018] Furthermore, both sides of the rotating rod are rotatably connected to the outer casing, and the front ends of the metal conductive sheet and the bimetallic sheet extend into the interior of the moving frame;

[0019] By using the above technical solution, by having the front ends of both the metal conductive sheet and the bimetallic sheet extend into the interior of the moving frame, the deformation of the bimetallic sheet causes the moving frame to move downward, which in turn causes the metal conductive sheet to disconnect from the metal contact, thus breaking the circuit.

[0020] Furthermore, all the gears are meshed with the rack, and the front end of the actuating rod extends through to the outside of the housing;

[0021] With the above technical solution, the gears are meshed with the rack, so that after the moving frame moves down, the rotating rod can drive the pressing rod to rotate, allowing the staff to intuitively understand whether the circuit is disconnected or not.

[0022] Furthermore, all the sliding rods slide inside the sliding groove, all the locking blocks are engaged with the limiting blocks, and all the metal blocks are engaged with the mounting blocks;

[0023] The above technical solution allows the sliding rod to slide inside the slide groove by pulling the limiting block, thereby releasing the jamming state between the locking block and the limiting block, and between the metal block and the mounting block, making it easier to remove the power protector from the mounting block.

[0024] This utility model has the following beneficial effects:

[0025] 1. The power protector proposed in this utility model uses a first reset spring in the installation mechanism to act on a sliding rod, which is fixedly connected to a limiting block. The limiting block is engaged with a locking block fixed to the upper end of the outer shell, and the mounting block is engaged with a metal block fixed to the lower end of the outer shell. This allows the operator to pull the limiting block to release the engagement between the limiting block and the locking block, thus facilitating disassembly and installation. It also makes it easier for the operator to disassemble the power protector for maintenance.

[0026] 2. The power supply protector proposed in this utility model uses an induction coil wound on a bobbin in the action mechanism to generate a strong magnetic field that attracts the top block to overcome the elastic force of the second reset spring, pushing the moving frame downwards and pressing the metal conductive plate away from the metal contact to disconnect the circuit, preventing excessive circuit current from damaging the equipment and preventing reverse polarity from damaging the equipment. The metal block fixedly connected to the lower end of the outer shell and the grounding wire fixedly connected to the lower end of the mounting block are used to conduct the static electricity accumulated on the outer shell to the ground, preventing static electricity from damaging the equipment. The bimetallic strip is heated by the surge current and deformed, causing the moving frame to move downwards. The moving frame, together with the metal conductive plate, presses the metal conductive plate away from the metal contact to disconnect the circuit, preventing surge current from damaging the equipment.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a specific embodiment of a power supply protector for a device, comprising two housings 1, a mounting mechanism 2, and an actuating mechanism 4. The mounting mechanism 2 is provided at the rear end of the housing 1, and the mounting mechanism 2 includes a mounting block 203. The actuating mechanism 4 is provided inside the housing 1, and the actuating mechanism 4 includes a top block 403, a moving frame 405, a rotating rod 407, and a limiting block 411. The front end of the inner wall of the housing 1 is fixedly connected to a fixing frame 3. The upper end of the inner wall of the front end of the fixing frame 3 is fixedly connected to a winding drum 401. The center of the inside of the fixing frame 3 is fixedly connected to a second reset spring 402. The outer wall of the winding drum 401 is wound with an induction coil 404. The middle part of the lower end of the fixing frame 3 is fixedly connected to a metal contact piece 412.

[0036] The lower end of the induction coil 404 passes through the fixed frame 3 and is fixedly connected to the metal contact 412. The two sides of the outer wall of the front end of the movable frame 405 are fixedly connected to the rack 406. The two sides of the outer wall of the rotating rod 407 are fixedly connected to the gear 408. The middle part of the outer wall of the rotating rod 407 is fixedly connected to the push rod 409. The rear end of the inner wall of the outer shell 1 is fixedly connected to the arc extinguishing grid 410. The middle part of the front end of the lower end of the arc extinguishing grid 410 is fixedly connected to the metal contact 412. The lower end of the arc extinguishing grid 410 is fixedly connected to the metal conductive sheet 413. The lower end of the inner wall of the outer shell 1 is fixedly connected to the first connecting block 5. The rear end of the upper end of the first connecting block 5 is fixedly connected to the bimetallic sheet 414.

[0037] The upper end of the second reset spring 402 is fixedly connected to the top block 403. The top block 403 slides inside the winding drum 401. The bimetallic strip 414 is connected to the metal conductive strip 413 through a wire. The induction coil 404 wound on the winding drum 401 generates a strong magnetic field that attracts the top block 403 to overcome the elastic force of the second reset spring 402, pushing the moving frame 405 downward. The bimetallic strip 414 is connected to the metal conductive strip 413 through a wire, connecting the circuit. This allows the metal conductive strip 413 to be moved away from the metal contact 413. 12. The circuit can be interrupted. The upper end of the induction coil 404 is fixedly connected to the second connecting block 6. The outer walls on both sides of the second connecting block 6 are fixedly connected to the outer shell 1. The second connecting block 6, which is fixedly connected to the upper end of the induction coil 404 and the second connecting block 6, which is fixedly connected inside the outer shell 1, can be connected to the external device circuit. The outer walls on both sides of the moving frame 405 are slidably connected to the outer shell 1. The limiting block 411 is located between the metal contact piece 412 and the moving frame 405 and slides inside the outer shell 1. The moving frame 405 slides against the inner wall of the outer shell 1. The moving connection allows the top block 403 to move downwards, pushing the moving frame 405 downwards. The push rod 409, fixedly connected to the middle of the rotating rod 407 via the limiting block 411, moves inside the housing 1, blocking the top of the moving frame 405 to prevent circuit disconnection. When the metal conductive sheet 413 returns to its original position, the moving frame 405 moves upwards. Both sides of the rotating rod 407 are rotatably connected to the housing 1. The front ends of the metal conductive sheet 413 and the bimetallic strip 414 extend into the interior of the moving frame 405. This allows the metal conductive sheet 413 and the bimetallic strip 414 to move upwards. The front ends of the bimetallic strip 414 extend into the interior of the movable frame 405. When the bimetallic strip 414 deforms and moves the movable frame 405 downward, it can cause the metal conductive strip 413 to disconnect from the metal contact strip 412, thus breaking the circuit. The gears 408 are all meshed with the rack 406. The front end of the push rod 409 extends through the outside of the outer shell 1. Through the meshing of the gears 408 with the rack 406, after the movable frame 405 moves downward, the rotating rod 407 can drive the push rod 409 to rotate, allowing the staff to intuitively understand whether the circuit is broken or not.

[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5The mounting block 203 has sliding grooves 204 on both sides of its upper end. A first return spring 205 is fixedly connected to the top of the sliding groove 204. A sliding rod 206 is fixedly connected to the lower end of the first return spring 205. A limiting block 207 is fixedly connected to the upper end of the outer wall of the front end of the sliding rod 206. A locking block 201 is fixedly connected to the rear end of the upper end of the outer shell 1. A metal block 202 is fixedly connected to the rear end of the lower end of the outer shell 1. A grounding wire 7 is fixedly connected to the middle of the lower end of the mounting block 203. The sliding rod 206 slides inside the sliding groove 204. The locking block 201 is locked to the limiting block 207. The metal block 202 is locked to the mounting block 203. By pulling the limiting block 207, the sliding rod 206 slides inside the sliding groove 204, which releases the locking state between the locking block 201 and the limiting block 207, and between the metal block 202 and the mounting block 203, making it easy to remove the power protector from the mounting block 203.

[0039] Working principle: When using the power protector, the operator first pulls the limiting block 207 to move the slide rod 206 inside the slide groove 204. Then, the power protector is installed on the mounting block 203. Next, it is connected to the power supply of an external device via the first connecting block 5 and the second connecting block 6. Then, the induction coil 404 wound on the winding drum 401 in the action mechanism 4 generates a strong magnetic field that attracts the top block 403, overcoming the elastic force of the second reset spring 402, and pushing the moving frame 405 downwards. This forces the metal conductive sheet 413 away from the metal contact sheet 412, disconnecting the circuit and preventing damage from excessive circuit current and reversed power polarity. The metal conductive sheet 413 is fixedly connected to the lower end of the outer casing 1. The grounding wire 7, which is fixedly connected to the lower end of the mounting block 203 and the block 202, conducts the static electricity accumulated on the outer casing 1 to the ground, preventing static electricity from damaging the equipment. The bimetallic strip 414 is heated by the surge current and deforms, causing the moving frame 405 to move downward. The moving frame 405 presses the metal conductive strip 413 away from the metal contact strip 412 to disconnect the circuit, preventing the surge current from damaging the equipment. Finally, the operator can pull the limiting block 207 to make the slide rod 206 slide inside the slide groove 204, so that the jamming state between the locking block 201 and the limiting block 207, and between the metal block 202 and the mounting block 203 can be released, making it easy to remove the equipment power protector from the mounting block 203 for repair or replacement of the damaged equipment power protector.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
