Description

Technical Field

[0001] This utility model relates to the field of electronic technology experimental equipment technology, specifically to a detachable electronic technology experimental box. Background Technology

[0002] An electronic technology experiment box is a device for electronic technology education and experimentation. It is mainly used to simulate experimental environments for various electronic circuits and systems, helping learners to conduct practical operations and verify theories.

[0059] refer to Figures 1 to 8 A detachable electronic technology experimental box includes a box body 1, a flip baffle 3, an operating handle 10, a sliding box body 13, an experimental circuit board 14, a lifting mechanism, a flipping mechanism, a disassembly and replacement mechanism, and a limit fixing mechanism.

[0060] The lower part of the front wall of the box 1 is provided with a first rectangular through hole 103. A flip baffle 3 is detachably installed in front of the first rectangular through hole 103. The first rectangular through hole 103 is a channel for the experimental circuit board 14 to pop out. The flip baffle 3 can block or open the first rectangular through hole 103 under the drive of the flipping mechanism described later.

[0061] The flip baffle 3 is rotatably mounted on the front wall of the housing 1, and the flip baffle 3 is driven to flip by the flipping mechanism.

[0062] A sliding box 13 is slidably installed inside the housing 1. An experimental circuit board 14 is movably installed inside the sliding box 13. The experimental circuit board 14 is detachably connected to the first rectangular through hole 103. The sliding box 13 is used to support the experimental circuit board 14. The experimental circuit board 14 has various modules for experimental use. When using the equipment, the sliding box 13, supporting the experimental circuit board 14, is lifted upward and is limited by the limiting and fixing mechanism described later.

[0063] The experimental circuit board 14 is driven to move by a disassembly and replacement mechanism. The disassembly and replacement mechanism is used to pop the experimental circuit board 14 out from the bottom of the housing 1 for easy and quick replacement.

[0064] The sliding box 13 is driven to rise and fall by a lifting mechanism;

[0065] The tilting mechanism is driven by the lifting mechanism.

[0066] An operating handle 10 is movably installed on the rear side of the housing 1. The operating handle 10 is operated by a lifting mechanism driven by the movement. The operating handle 10 can only be operated after the user contacts the limiting and fixing mechanism described later.

[0067] A limiting and fixing mechanism for fixing the operating handle 10 is installed on the rear wall of the housing 1.

[0068] The lifting mechanism includes a rectangular slider 1301, a first connecting rod 5, and a first return spring;

[0069] The bottom of the sliding box 13 is connected to the upper end of the bottom wall of the box 1 by a number of first return springs;

[0070] Rectangular sliders 1301 are fixedly installed on the left and right side walls of the sliding box 13, respectively;

[0071] Rectangular barrel grooves 101 are provided on both sides of the box body 1, and two rectangular sliders 1301 are slidably installed in the rectangular barrel grooves 101 that are close to them.

[0072] Two rectangular sliders 1301 are respectively fixedly installed on the outer walls of the first connecting shafts, and the first ends of the first connecting rods 5 are respectively fixedly installed on the outer walls of the two first connecting shafts.

[0073] The operating handle 10 is fixedly installed between the second ends of the two first connecting rods 5 respectively;

[0074] The two first connecting rods 5 operate through a sliding drive flipping mechanism. When the limiting and fixing mechanism described later is released, the operating armrest 10 can be pressed down by the user's grip. The first connecting rods 5 located at both ends of the operating armrest 10 can then move downward synchronously with the movement of the operating armrest 10. During the downward movement, the two first connecting rods 5 can respectively drive the rectangular sliders 1301 on both sides to begin sliding downward along the rectangular barrel grooves 101 that they cooperate with. The sliding box 13 fixedly installed between the two rectangular sliders 1301 can then slide downward in the box 1 along with the rectangular sliders 1301 on both sides. As the sliding box 13 moves downward, it will begin to compress several first return springs. When the user stops applying force to the operating armrest 10, the several first return springs can reset, causing the sliding box 13 to bounce upward again, thus achieving reset.

[0075] The limiting and fixing mechanism includes a first rectangular block 11 and a limiting screw 12;

[0076] A first rectangular block 11 is fixedly installed on the rear wall of the housing 1, and a limit screw 12 is connected to the internal thread of the first rectangular block 11;

[0077] The operating handle 10 is detachably connected to the limiting screw 12. When the operating handle 10 is reset upward by several first reset springs, it will be above the first rectangular block 11. At this time, the limiting screw 12 is screwed into the first rectangular block 11, which can block the downward movement of the operating handle 10. When the user operates the experimental circuit board 14 inside the box 1, it will not fall downward, which increases the stability during operation. When it is necessary to release the limit, simply unscrew the limiting screw 12 out of the first rectangular block 11.

[0078] The flipping mechanism includes a T-shaped slider 801, a connecting plate 8, a second rectangular block 9, a second connecting rod 7, a third connecting rod 6, and a fourth connecting rod 2;

[0079] The lower part of the left and right side walls of the box 1 is fixedly installed with a second rectangular block 9, and the two second rectangular blocks 9 are respectively installed below the rectangular barrel trough 101 that are close to them;

[0080] Each of the two second rectangular blocks 9 is provided with a T-shaped groove 901. A horizontal plate of a T-shaped slider 801 is slidably installed in each of the two T-shaped grooves. A connecting plate 8 is fixedly installed in each of the two T-shaped sliders 801 through the adjacent T-shaped groove 901.

[0081] Two connecting shafts are fixedly installed on the outer walls of the two connecting plates 8 respectively, and the first end of the third connecting rod 6 is rotatably fitted onto the outer ends of the two second connecting shafts respectively.

[0082] A third connecting shaft is fixedly installed on the outer wall of the first end of each of the two first connecting rods 5, and the second ends of the two third connecting rods 6 are respectively rotatably fitted onto the outer wall of the third connecting shaft that is close to them;

[0083] The first ends of the second connecting rods 7 are rotatably mounted on the two second connecting shafts respectively, and the two second connecting rods 7 are movably installed on the inner side of the third connecting rod 6 that is close to them;

[0084] The first ends of the fourth connecting rods 2 are rotatably installed on both sides of the front wall of the housing 1, and the flip baffle 3 is fixedly installed between the two fourth connecting rods 2;

[0085] A fourth connecting shaft is fixedly installed on the outer wall of the middle end of each of the two fourth connecting rods 2. The second ends of the two second connecting rods 7 are respectively rotatably fitted onto the outer wall of the adjacent fourth connecting shaft. (Refer to...) Figure 1When the two rectangular sliders 1301 slide downwards, they respectively drive the two third connecting rods 6 to start deflecting downwards. While the two third connecting rods 6 deflect downwards, they will drive the connecting plates 8 on both sides to start sliding forward. The sliding trajectory of the T-shaped slider 801, which is fixedly connected to the two connecting plates 8, is limited by the T-shaped groove 901. Therefore, the two connecting plates 8 will not deviate or fall off during the sliding process. As the two connecting plates 8 slide forward, they will respectively drive the second connecting rods 7 on both sides to start deflecting upwards. During the upward deflection of the two second connecting rods 7, they will respectively drive the fourth connecting rods 2 on both sides to start rotating upwards around their respective rotation centers. The flipping baffle 3, which is fixedly installed between the two fourth connecting rods 2, flips upwards synchronously with the two fourth connecting rods 2, exposing the first rectangular through hole 103, providing a channel for the subsequent ejection of the experimental circuit board 14.

[0086] The disassembly and replacement mechanism is the second return spring 15;

[0087] The rear wall of the experimental circuit board 14 is connected to the rear wall of the sliding box 13 by a number of second return springs 15.

[0088] The front wall of the sliding box 13 is provided with a second rectangular through hole 1302, and the second rectangular through hole 1302 is detachably connected to the first rectangular through hole 103.

[0089] The experimental circuit board 14 is detachably installed in the second rectangular through hole 1302. When the user operates the sliding box 13 to slide down to the bottom, the second rectangular through hole 1302 and the first rectangular through hole 103 are connected. At this time, there is no obstruction on the front wall of the experimental circuit board 14 located in the sliding box 13. Under the reset of several second return springs 15, the experimental circuit board 14 is ejected outward from the two connected rectangular through holes. After ejection, the user can insert the new experimental circuit board from the two connected rectangular through holes, causing the several second return springs 15 at its rear end to start compressing. After it is fully inserted, stop applying force to the operating handle 10, and the sliding box 13 will be lifted up under the reset of several first return springs. At this time, the front wall of the new experimental circuit board 14 is blocked again by the inner side of the front wall of the box 1, thus achieving its limitation in the sliding box 13.

[0090] A fixed baffle 102 is installed on the rear of the top wall of the box 1. The sliding box 14 is detachably installed below the fixed baffle 102. The fixed baffle 102 is used to block the sliding box 13.

[0091] A flip-top plate 4 is rotatably mounted on the front wall of the fixed baffle 102. The flip-top plate 4 is movably mounted above the sliding box 13. The flip-top plate 4 is connected to the front wall of the box 1 via a buckle 401. The flip-top plate 4 protects the top of the experimental circuit board 14 when the equipment is stored, preventing it from being exposed to air for a long time and causing circuit oxidation.

[0092] The implementation method of this utility model:

[0093] When this device is in its initial state, such as Figure 8 As shown in A, the flip-top plate 4 is completely closed by the buckle 401, and the flip-up baffle 2 below the front wall of the box 1 also completely blocks the first rectangular through hole 103 on the front side of the box 1. The sliding box 13 is located at the top of the box 1 under the upward elastic force of several first reset springs and is blocked by the fixed baffle 102. At this time, the limit screw 12 is inserted into the first rectangular block 11 to prevent the operating handle 10 from sliding down. This state is suitable for moving the equipment or for long-term storage.

[0094] When the equipment needs to be used, simply open the latch 401 to flip the top plate 4 upwards, exposing the experimental circuit board 14 located inside the housing 1, as shown below. Figure 8 As shown in B, experimental training can now begin on experimental circuit board 14.

[0095] When the experimental circuit board 14 needs to be replaced, unscrew the limiting screw 12 located on the rear wall of the housing 1, and press down on the operating handle 10. As the operating handle 10 moves downward, the sliding box 13 begins to move downward. Simultaneously, the flip-up baffle 2 located below the front wall of the housing 1 opens upward. When the second rectangular through hole 1302 on the front wall of the sliding box 13 and the first rectangular through hole 103 on the front wall of the housing 1 slide to connect, the experimental circuit board 14 inside the sliding box 13 will pop outward under the reset of several second return springs 15. Figure 8 As shown in Figure C, the old circuit board is removed, and the new circuit board is inserted through the two connected rectangular through holes. The circuit board gradually presses down on several second return springs 15, causing them to gradually return to a compressed state. Once the new circuit board is fully inserted, the pressure on the operating handle 10 stops, and the sliding box 13, carrying the new circuit board, slides upward again within the housing 1. As the sliding box 13 slides upward, the flip-up baffle 2 closes again, causing the device to revert to its original state. Figure 8 The state shown in B.

[0096] When replacing the experimental circuit board, this utility model only requires releasing the disassembly and assembly limiting mechanism to drive the operating handle. By driving the operating handle, the flip-up baffle under the box can be opened, and at the same time, the sliding box carrying the circuit board slides towards the first rectangular through hole below. When the first rectangular through hole connects with the second rectangular through hole, the experimental circuit board will be quickly popped out by several second reset springs. Disassembly and assembly are convenient and simple, greatly saving resources.

[0097] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
