Description

Technical Field

[0001] This utility model relates to the field of current transformer technology, specifically a current transformer that can be quickly disassembled and assembled. Background Technology

[0002] Instrument transformers, also known as instrument transformers, are a general term for current transformers and voltage transformers. They can transform high voltage into low voltage and large current into small current, and are used in measurement or protection systems. Their main function is to proportionally transform high voltage or large current into standard low voltage or standard small current, so as to realize the standardization and miniaturization of measuring instruments, protection equipment, and automatic control equipment.

[0003] Currently, in existing technologies, current transformers are typically installed by using a connecting plate at the bottom of the transformer to clip onto a guide rail inside the distribution box, and then reinforced with twin or quad screws. This installation method makes it inconvenient to install and remove the current transformer. Therefore, there is a need to propose a current transformer that can be quickly installed and removed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the current transformers use a snap-fit ​​connection and screw reinforcement method, which makes disassembly and assembly inconvenient. This utility model proposes a current transformer that can be quickly disassembled and assembled.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a current transformer that can be quickly disassembled and assembled, including a current transformer body, a base fixedly connected to the bottom of the current transformer body, a buckling mechanism provided in the inner cavity of the base, and a guide rail snapped into the end of the buckling mechanism. The latching mechanism includes a screw rod rotatably connected to the top of the inner cavity of the base. A knob is fixedly connected to the outer wall of the screw rod near the top of the screw rod. A threaded sleeve is threadedly connected to the outer wall of the screw rod. Connecting rods are rotatably connected to both sides of the threaded sleeve. A pressure block is rotatably connected to one end of the connecting rod. Slider blocks are slidably connected to both sides of the inner cavity of the base. The pressure block and the slider slide together. A spring is provided on one side of the slider. One end of the slider extends out of the side wall of the base and engages with the guide rail.

[0006] Preferably, a rotating groove is provided on one side of the base, and the knob is rotatably connected inside the rotating groove, with the outer wall of the knob extending out of both sides of the base.

[0007] Preferably, the pressure block has a first inclined surface on both sides, and the slider has a second inclined surface on the opposite side, with the first and second inclined surfaces in contact.

[0008] Preferably, a first positioning rod is fixedly connected to the top of the inner cavity of the base, and one end of the first positioning rod passes through the pressure block and is slidably connected to the pressure block.

[0009] Preferably, a second positioning rod is fixedly connected to the inner wall of the base cavity, and one end of the second positioning rod passes through the slider and is slidably connected to the slider.

[0010] Preferably, one end of the spring is fixedly connected to the side wall of the slider, and the other end of the spring is fixedly connected to the side wall of the inner cavity of the base, with the second positioning rod passing through the axis of the spring.

[0011] Preferably, one end of the slider is provided with a slot, and the upper edge of the inner wall of the guide rail is provided with a hook, and the slot and the hook are engaged to engage.

[0012] The advantages of this utility model are: This invention fixes the guide rail to the inner wall of the distribution box, then inserts the base into the inner cavity of the guide rail. Rotating the knob clockwise drives the screw to rotate, which in turn drives the threaded sleeve to slide downwards. The threaded sleeve, through a connecting rod, drives the pressure block to slide downwards. The pressure block slides down and pushes the sliders on both sides outwards. The ends of the sliders are tightly locked onto the upper edge of the inner wall of the guide rail, allowing the current transformer body to be quickly installed on the guide rail. Rotating the knob counterclockwise removes the pressure block from the slider, and the spring's rebound force pushes the slider to slide in the opposite direction, separating the slider from the upper edge of the inner wall of the guide rail. This allows the current transformer body to be quickly removed from the guide rail, achieving the effect of rapid assembly and disassembly of the current transformer body. This solves the problem that the existing current transformers, which use a snap-fit ​​connection and screw reinforcement method, are relatively inconvenient to assemble and disassemble.

[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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a current transformer that can be quickly installed and disassembled. (Refer to...) Figures 1-5 A quick-release current transformer includes a current transformer body 1, a base 2 fixedly connected to the bottom of the current transformer body 1, a latching mechanism 3 provided in the inner cavity of the base 2, and a guide rail 4 latched at the end of the latching mechanism 3. By fixing the guide rail 4 to the inner wall of the distribution box, the base 2 and the current transformer body 1 are latched into the inner cavity of the guide rail 4. Rotating the rotating end of the latching mechanism 3 in the forward direction, the end of the latching mechanism 3 is stably latched with the upper edge of the inner wall of the guide rail 4, so that the current transformer body 1 can be quickly installed on the guide rail 4. Rotating the rotating end of the latching mechanism 3 in the reverse direction, the end of the latching mechanism 3 is separated from the upper edge of the inner wall of the guide rail 4, so that the base 2 and the current transformer body 1 can be quickly removed from the guide rail 4, thereby achieving the purpose of quick-release of the current transformer body 1. The latching mechanism 3 includes a screw 31, which is rotatably connected to the top of the inner cavity of the base 2. A knob 32 is fixedly connected to the outer wall of the screw 31 near the top of the screw 31. A threaded sleeve 33 is threadedly connected to the outer wall of the screw 31. Connecting rods 34 are rotatably connected to both sides of the threaded sleeve 33. A pressure block 35 is rotatably connected to one end of the connecting rod 34. Sliding blocks 37 are slidably connected to both sides of the inner cavity of the base 2. The pressure block 35 and the sliding block 37 cooperate to slide. A spring 39 is provided on one side of the sliding block 37. One end of the sliding block 37 extends out of the side wall of the base 2 and engages with the guide rail 4. When the bottom of the base 2 is engaged with the inner cavity of the guide rail 4, it pushes the knob 32 to rotate in the forward direction. The rotation of the knob 32 causes the screw 31 to be positioned at the top of the inner cavity of the base 2. Rotating the screw 31 causes it to rotate and drive the threaded sleeve 33 to slide downwards. The threaded sleeve 33 pushes the pressure block 35 downwards via the connecting rod 34. The pressure block 35 pushes the sliders 37 on both sides to slide outwards from the base 2. The sliders 37 slide and compress the spring 39. The end of the slider 37 is stably locked to the upper edge of the inner wall of the guide rail 4, thus achieving the purpose of quick installation of the transformer body 1. Rotating the knob 32 in the opposite direction removes the restriction of the pressure block 35 on the slider 37. The rebound force of the spring 39 pushes the slider 37 to slide in the opposite direction. The end of the slider 37 separates from the upper edge of the inner wall of the guide rail 4, so that the base 2 and the transformer body 1 can be quickly removed from the guide rail 4, thus achieving the purpose of quick disassembly of the transformer body 1.

[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A rotating groove 21 is provided on one side of the base 2. A knob 32 is rotatably connected inside the rotating groove 21. The outer wall of the knob 32 extends out of both sides of the base 2. A first inclined surface 36 is provided on both sides of the pressure block 35. A second inclined surface 38 is provided on the opposite side of the slider 37. The first inclined surface 36 and the second inclined surface 38 are in contact. A first positioning rod 310 is fixedly connected to the top of the inner cavity of the base 2. One end of the first positioning rod 310 passes through the pressure block 35 and is slidably connected to the pressure block 35. The knob 32 can be easily pushed to rotate by extending out of the side wall of the base 2. The forward rotation of the knob 32 drives the screw 31 to be located in the base 2. When the inner cavity rotates, the screw 31 rotates and drives the threaded sleeve 33 to slide downward. The threaded sleeve 33 drives the pressure block 35 to slide downward through the connecting rod 34. The pressure block 35, in conjunction with the first positioning rod 310, slides downward stably. The pressure block 35, through the cooperation of the first inclined surface 36 and the second inclined surface 38 of the slider 37, pushes the slider 37 to slide outward, thereby achieving the purpose of the pressure block 35 pushing the slider 37 to slide outward of the base 2. When the knob 32 is rotated in the opposite direction, the threaded sleeve 33 slides upward. The threaded sleeve 33 drives the pressure block 35 to slide upward through the connecting rod 34, thereby removing the restriction of the pressure block 35 on the slider 37.

[0019] Reference Figure 2 , Figure 4 and Figure 5A second positioning rod 311 is fixedly connected to the inner wall of the base 2. One end of the second positioning rod 311 passes through the slider 37 and is slidably connected to the slider 37. One end of the spring 39 is fixedly connected to the side wall of the slider 37, and the other end of the spring 39 is fixedly connected to the side wall of the inner cavity of the base 2. The second positioning rod 311 passes through the axis of the spring 39. A slot 312 is provided at one end of the slider 37, and a hook 41 is provided along the upper edge of the inner wall of the guide rail 4. The slot 312 and the hook 41 engage. By rotating the knob 32 in the forward direction, the pressure block 35 pushes the slider 37 to slide outward of the base 2. The slider 37 slides and compresses the spring 39. The slot 312 at the end of slider 37 engages with the hook 41 on the upper edge of the inner wall of guide rail 4 to securely lock the slider 37. The slider 37 can slide horizontally stably with the second positioning rod 311. At this time, the transformer body 1 is stably installed on the guide rail 4. By rotating the knob 32 in the opposite direction, the pressure block 35 slides upward and removes the restriction on the slider 37. The rebound force of the spring 39 pushes the slider 37 to slide in the opposite direction. The slot 312 at the end of slider 37 separates from the hook 41 on the upper edge of the inner wall of guide rail 4, thereby achieving the purpose of separating slider 37 from guide rail 4. At this time, the base 2 and the transformer body 1 can be quickly removed from guide rail 4.

[0020] Working principle: During installation, the guide rail 4 is fixed to the inner wall of the distribution box. The base 2 is stably locked in place by the snap-fit ​​mechanism 3 pressing against the inner wall of the guide rail 4, thus achieving the purpose of quick installation of the transformer body 1. First, the base 2 is inserted into the inner cavity of the guide rail 4. Then, the knob 32 in the rotating groove 21 is pushed to rotate in the forward direction. The knob 32 drives the screw 31 to rotate. The screw 31 rotates and drives the threaded sleeve 33 to slide downward. The threaded sleeve 33 drives the pressure block 35 to slide downward through the connecting rod 34. The pressure block 35 slides downward stably with the first positioning rod 310. The pressure block 35 uses the first inclined surface 36 and the second inclined surface 38 of the slider 37 to push the slider 37 to slide outward of the base 2. The slider 37, with the second positioning rod 310, slides downward stably. Position rod 311 can slide horizontally stably. Slider 37 slides and compresses spring 39. The end of slider 37 and slot 312 are stably locked with hook 41 on the upper edge of the inner wall of guide rail 4, so that transformer body 1 can be quickly installed on guide rail 4. When disassembling, rotate knob 32 in the opposite direction. Threaded sleeve 33 slides upward on the outer wall of screw 31. Threaded sleeve 33 drives pressure block 35 to slide upward through connecting rod 34. Pressure block 35 removes its restriction on slider 37. The rebound force of spring 39 pushes slider 37 to slide in the opposite direction. Slot 312 at the end of slider 37 separates from hook 41 on the upper edge of the inner wall of guide rail 4, so that base 2 and transformer body 1 can be quickly removed from guide rail 4.
