Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit module teaching technology, and more specifically, to a combinable circuit module kit for electrical and electronic experimental teaching. Background Technology
[0002] Electrical and electronic experimental teaching is an important part of the study of electrical engineering, electronic engineering and related fields. It aims to help students understand theoretical knowledge and cultivate their ability to solve practical problems through hands-on operation. Modular circuit module kits are a very practical teaching tool designed to help students better understand and master the basic principles and practical applications of electronic circuits. These kits usually contain a series of circuit modules with different functions, such as power supply modules, signal generators, amplifiers, filters, etc. These modules can be connected by wires or dedicated interfaces to form different circuit configurations to achieve various experimental purposes.
[0003] Existing teaching circuit demonstration tools mostly use a large PCB board covered with various electrical components. The PCB board is then fixed to a blackboard, and various wires are used to connect and demonstrate to students. During teaching, appropriate electronic components, such as resistors, capacitors, diodes, transistors, and integrated circuits, are selected according to the demonstration purpose. The selected electronic components are soldered onto the PCB board. Appropriate brackets or adhesives can be used to securely fix the PCB board to the blackboard or other vertical surfaces. Necessary annotations are added around the blackboard with chalk or markers to explain the function of each component and its connection method. Students are encouraged to participate and try to connect different electronic components themselves to enhance their learning experience.
[0004] In practical applications, existing technologies often present challenges. Traditional teaching methods for circuit module experiments typically require placing the circuit board flat on the podium and then electrically connecting multiple electronic components to it, which can create blind spots and prevent students from clearly seeing the teacher's detailed operations. Therefore, a combinable circuit module kit for electrical and electronic experimental teaching is proposed. Utility Model Content
[0005] 1. Technical problems to be solved
[0006] To address the problems existing in the prior art, this utility model provides a combinable circuit module kit for electrical and electronic experimental teaching. It adjusts the position of the movable seat by rotating the handle to drive the screw to rotate. When the movable seat moves, it pushes the fixed seat and mounting plate upward to rotate through the support rod, thereby adjusting the display angle of the circuit board so that the teaching operation can be more fully displayed to the students. It is suitable for the teaching needs of different application scenarios. Compared with the traditional method of placing it directly on the podium for teaching operation, it can eliminate blind spots and thus improve the teaching quality.
[0007] 2. Technical Solution
[0008] To solve the above problems, the present invention adopts the following technical solution.
[0009] A modular circuit kit for electrical and electronic experimental teaching includes a mounting plate, assembly components, and adjustment components. The mounting plate is hinged to a base plate via a shaft. The assembly components are mounted on the mounting plate. The adjustment components, including mounting rods symmetrically fixed to the mounting plate, have crescent-shaped grooves. A circuit board is movably connected within these crescent-shaped grooves. Crescent-shaped slots are formed on the mounting plate below the mounting rods. Crescent-shaped blocks are interspersed within the crescent-shaped slots and the inner cavity of the base plate. Multiple slots are evenly distributed on the circuit board. Anti-slip sleeves are fixedly connected to the inner wall of each slot. A connector is interspersed within each slot, with one end of the connector attached to an electronic component body. A fixing plate is fixedly connected to the upper surface of the base plate. A screw is rotatably connected to one side of the base plate, and a movable seat is threaded onto the outer surface of the screw. A fixing seat is fixedly connected to the side of the mounting plate away from the circuit board, and a support rod is hinged to the inner cavity of the movable seat.
[0010] Furthermore, a pull rod is fixedly connected to one side of the crescent block, and one end of the pull rod abuts against the mounting plate.
[0011] Furthermore, a spring is fitted onto the outer surface of the pull rod, and both ends of the spring are fixedly connected to the handle of the pull rod and the mounting plate, respectively.
[0012] Furthermore, the bottom of the slot cavity is inlaid with endpoint one, and the end of the connector away from the electronic component body is inlaid with endpoint two. Endpoint one and endpoint two abut against each other, and the inner side of the anti-slip sleeve is provided with continuous arc-shaped protrusions.
[0013] Furthermore, the end of the screw away from the base plate is fixedly connected to a rotating handle through the fixing plate, and the movable seat moves on the upper surface of the base plate.
[0014] Furthermore, the end of the support rod away from the movable seat is hinged to the inner cavity of the fixed seat, and there are two support rods symmetrically arranged on both sides of the screw.
[0015] 3. Beneficial effects
[0016] Compared with existing technologies, the advantages of this utility model are:
[0017] (1) This solution adjusts the position of the moving seat by rotating the screw through the rotating handle. When the moving seat moves, it will push the fixed seat and the mounting plate to flip upward through the support rod, thereby adjusting the display angle of the circuit board so that the teaching operation can be displayed to the students more completely. It is suitable for teaching needs in different application scenarios. Compared with the traditional method of placing it directly on the podium for teaching operation, it can eliminate blind spots and thus improve teaching quality.
[0018] (2) In this design, the circuit board is placed on the mounting rod and moved to abut against the mounting plate and lock into the crescent-shaped groove on the mounting rod. The spring itself drives the crescent block back to its original position and into the inner cavity of the circuit board to lock the circuit board on the mounting plate. During teaching, the connectors installed on the electronic component body are inserted into the slots. At this time, endpoint one and endpoint two contact to achieve electrical connection. The anti-slip sleeve increases the friction between the two to ensure the stability and safety of the connector and slot connection. Different types of electronic components can be installed and removed quickly and frequently. It is especially suitable for experimental teaching that requires multiple demonstrations. This design can facilitate students and teachers to quickly build and test different circuit configurations and improve learning efficiency. Attached Figure Description

[0030] Example 1
[0031] Reference Figure 1-6This is the first embodiment of the present invention. This embodiment provides a combinable circuit module kit for electrical and electronic experimental teaching, including a mounting plate 1. The mounting plate 1 is hinged to a base plate 101 via a shaft. An assembly component 2 is mounted on the mounting plate 1, including mounting rods 201 symmetrically fixedly connected to the mounting plate 1. The mounting rods 201 have crescent-shaped grooves. A circuit board 202 is movably connected in the crescent-shaped grooves on the mounting rods 201. Crescent grooves 206 are provided on the mounting plate 1 below the mounting rods 201. Crescent blocks 205 are interposed in the crescent grooves 206 and the inner cavity of the base plate 101. Multiple slots 207 are evenly provided on the circuit board 202. Anti-slip sleeves 209 are fixedly connected to the inner sidewall of the slot 207. A connector 211 is interposed in the inner cavity of the slot 207. One end of the connector 211 is installed in the electronic component body 210.
[0032] Specifically, a pull rod 203 is fixedly connected to one side of the crescent block 205. One end of the pull rod 203 abuts against the mounting plate 1. A spring 204 is sleeved on the outer surface of the pull rod 203. Both ends of the spring 204 are fixedly connected to the handle of the pull rod 203 and the mounting plate 1, respectively. An end point 208 is embedded in the bottom of the inner cavity of the slot 207. An end point 212 is embedded in the end of the connector 211 away from the electronic component body 210. End point 208 abuts against end point 212. A continuous arc-shaped protrusion is provided on the inner side of the anti-slip sleeve 209.
[0033] Furthermore, the mounting plate 1 and the base plate 101 form an adjustable base, providing structural support and a mounting foundation for the circuit module. In use, first pull the lever 203 backward, then put the circuit board 202 on the mounting rod 201 and move it to abut against the mounting plate 1. Then move the circuit board 202 downward and lock it into the crescent-shaped groove on the mounting rod 201. Then release the lever 203, and the spring 204 will drive the crescent block 205 back to its original position and enter the inner cavity of the circuit board 202 to lock the circuit board 202 on the mounting plate 1, ensuring a stable installation.
[0034] The circuit board 202 (PCB) carries the core components of the electronic components. The crescent groove 206 and the crescent block 205 work together to ensure that the crescent block 205 can be correctly inserted and locked. During teaching, the connector 211 installed on the electronic component body 210 is inserted into the slot 207. At this time, the first end 208 and the second end 212 make contact and realize electrical connection. The friction between the two is increased by the anti-slip sleeve 209 and its surface arc protrusion to ensure the stability and safety of the connector 211 and the slot 207 when they are connected. Different types of electronic component bodies 210 can be installed and removed quickly and frequently. Different teaching experiments can be realized by combining different types of circuit modules. The first end 208 is a contact point on the circuit board 202. The electronic component body 210 is the actual functional component, such as resistor, capacitor, integrated circuit, etc. The second end 212 is another contact point.
[0035] Example 2
[0036] Reference Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. An adjustment component 3 is installed on the upper surface of the base plate 101. The adjustment component 3 includes a fixed plate 301 fixedly connected to the upper surface of the base plate 101. A screw 302 is rotatably connected to one side of the base plate 101. A movable seat 304 is threadedly connected to the outer surface of the screw 302. A fixed seat 305 is fixedly connected to the side of the mounting plate 1 away from the circuit board 202. A support rod 306 is hinged to the inner cavity of the movable seat 304.
[0037] Specifically, the end of the screw 302 away from the base plate 101 passes through the fixed plate 301 and is fixedly connected to the handle 303. The movable seat 304 moves on the upper surface of the base plate 101. The end of the support rod 306 away from the movable seat 304 is hinged to the inner cavity of the fixed seat 305. There are two support rods 306 symmetrically arranged on both sides of the screw 302.
[0038] Furthermore, placing the circuit board 202 directly on the podium for teaching operations would create certain blind spots, thus affecting the teaching quality. In this case, the position of the movable seat 304 can be adjusted by rotating the handle 303 to drive the screw 302 to rotate. When the movable seat 304 moves, it will push the fixed seat 305 and the mounting plate 1 to flip upward through the support rod 306, thereby adjusting the display angle of the circuit board 202 so that the teaching operation can be more fully displayed to the students, which is suitable for the teaching needs of different application scenarios.
[0039] Working principle: During device use, first pull the lever 203 backward, then place the circuit board 202 onto the mounting rod 201 and move it to abut against the mounting plate 1. Then, move the circuit board 202 downward and lock it into the crescent-shaped groove on the mounting rod 201. Release the lever 203, and the spring 204's own elasticity will cause the crescent block 205 to return to its original position and enter the inner cavity of the circuit board 202, locking the circuit board 202 onto the mounting plate 1 to ensure a stable installation. During teaching, insert the connector 211 installed on the electronic component body 210 into the slot 207. Point 1 208 and point 2 212 make contact to achieve electrical connection, and the friction between them is increased by the anti-slip sleeve 209 to ensure the stability and safety of the connection between the plug 211 and the slot 207. During teaching, if the circuit board 202 is placed directly on the podium, there will be a certain blind spot, which will affect the teaching quality. At this time, the position of the moving seat 304 can be adjusted by rotating the handle 303 to drive the screw 302 to rotate. When the moving seat 304 moves, it will push the fixed seat 305 and the mounting plate 1 to flip upward through the support rod 306, thereby adjusting the display angle of the circuit board 202.
[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
