[0015] Figure 1 The structure of the utility model is shown in FIG. Figure 1 .

[0016] Figure 2 The structure of the utility model is shown in FIG. Figure 2 .

[0017] Figure 3 for Figure 1 Schematic diagram of the AA section structure.

[0018] Figure 4 It is a schematic diagram of the cover and the main body being separated. DETAILED DESCRIPTION

[0019] refer to Figure 1-4 It can be seen that the utility model discloses a push-button resistor box, including a box body 1, a resistor assembly and a terminal 6, the resistor assembly includes a resistance adjustment key 3, a digital display 4 and an electronic component 5, the resistance adjustment key 3 and the digital display 4 are located on the outside of the box body 1, the electronic component 5 is located on the inside of the box body 1, and the outer side of the electronic component 5 is wrapped by a cover body, so when the box body is used as a toolbox, the electronic component 5 located in the box body 1 will not be damaged.

[0020] The resistor assembly is in decimal format. Figure 1 As shown, two resistance adjustment keys 3 and the corresponding digital display 4 form a group, and each group represents a digit, such as the ones digit is "X1", the tens digit is "X10", the hundreds digit is "X100", and so on.

[0021] The box body 1 comprises a main body 11 and a cover body 12. The cover body 12 is rotatably connected to the main body 11 on one side and can be opened and closed on the other side.

[0022] The resistance adjustment key 3 and the digital display 4 are arranged on the cover body 12 , and the electronic energy component 5 is located inside the cover body 12 .

[0023] The body 11 is provided with a limiting member 111 , the cover body 12 is provided with a connecting member 7 , and the connecting member 7 is provided with a limiting hole 71 corresponding to the limiting member 111 .

[0024] The end of the connecting member 7 is tilted outwardly 70, as shown in the attached Figure 2-3 As shown, the outward tilting arrangement 70 facilitates the opening operation of the cover 12. Compared with the conventional resistor box with a fixed connection (the screw connection cannot be easily opened), the cover 12 and the body 11 in the present application are openable, which facilitates the placement of some tools (connecting wires, etc.) in the box 1, so that the box 1 acts as a tool box and fully utilizes resources.

[0025] The connecting member 7 and the cover body 12 are movably connected. Preferably, the movable connection is a swing connection. When the cover body 12 and the connecting member 7 are both made of plastic material, a relatively soft plastic material is used at the connection between the cover body 12 and the connecting member 7, thereby achieving a swingable connection between the connecting member 7 and the cover body 12.

[0026] The cover 12 and the main body 11 are connected at a concave 8. Figure 2 As shown, the recess 8 is convenient for "hiding" the connecting member 7 and the limiting member 111 in the recess 8, so that the connecting member 7 and the limiting member 111 will not protrude from the surface of the box body 1 where the recess 8 is set, thereby protecting the connecting member 7 and the limiting member 111 and making the overall appearance of the box body 1 neat and tidy, reducing the occupied space.

[0027] The main body 11 is provided with a spare groove 2. According to consumer demand, a magnet is embedded in the spare groove 2. The magnet is adsorbed on the blackboard for display during teaching. It is easy to use and applicable to various scenarios.

[0028] Specifically, as attached Figure 1 As shown, the resistance box is connected to the circuit through the terminal 6, and then the required resistance value of the resistance box is adjusted to the desired value through the resistance adjustment key 3, and the resistance value is directly read according to the digital display, which is intuitive and accurate. Open the cover 12, and the box 1 can be used as a tool box.

[0029] This new functional model effectively improves the existing knob-type resistance box, which has slow reading speed, is not intuitive, has inaccurate reading, and occupies a large space. By setting the knob type to a button type, the product structure is compact, and the digital arrangement improves the intuitive accuracy of the reading, making the measurement result more accurate and reliable; at the same time, the box body 1 is set to be easy to open and close, and by increasing the volume of the box body 1, the box body 1 can hold items and be used as a toolbox, which makes full use of resources; the box body 1 is provided with a spare groove 2. According to the product application scenario, a magnet is embedded in the spare groove 2, which is adsorbed on the blackboard, which is convenient for teaching and has strong practicality.

[0030] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
