[0024] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0025] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] like Figure 1-2 The above-mentioned traffic light teaching demonstration device for preschool children comprises a gantry fixing frame 1, at least two gate stoppers 3, a driving component, a signal light 2, a circuit element 7, a battery pack 8 and a control switch 5. The gantry fixing frame 1 has two columns 101 and a crossbeam 102, and the crossbeam 102 is horizontally connected between the two columns 101, so the gantry fixing frame 1 forms a walking channel, and the two columns 101 and the crossbeam 102 are hollow structures inside, and the internal cavity is used to provide installation space and a wiring channel for wires.

[0027] In the present application, two gate stops 3 are provided according to the actual space size, and the two gate stops 3 are correspondingly rotatably provided on the two columns 101, so that each gate stop 3 can rotate relative to the column 101 to which it is connected, and the rotation center axis here is provided in parallel with the column 101, and the gate stop 3 is perpendicular to the column 101 in the initial position, and the two gate stops 3 are between the two columns 101, blocking the walking passage formed by the gantry fixing frame 1, and when the gate stop 3 rotates, its maximum rotation angle is 90°, and when it rotates 90°, the plane where the gate stop 3 is located is parallel to the column 101, and at this time the walking passage of the gantry fixing frame 1 is accessible.

[0028] The rotation of the gate stopper 3 is driven by a driving component, and the driving component is connected to the gate stopper 3 to drive the gate stopper 3 to rotate.

[0029] A signal light 2 is arranged on the crossbeam 102. The signal light 2 has three colors. The three colors of the signal light 2 can be realized by controlling one light with a circuit board to switch the three colors, or by three lights corresponding to three colors. According to the rules of traffic lights in my country, red light prohibits passage, green light allows passage, and yellow is a warning. When the red light is on, the gate blocker 3 blocks the walking passage formed by the gantry fixing frame 1 and does not allow passage. When the green light is on, the gate blocker 3 rotates 90°, and the walking passage formed by the gantry fixing frame 1 allows passage. The child is informed to pass through the gantry fixing frame 1 under the care of an adult. Through the above demonstration device, the child can personally experience passing through the gantry fixing frame 1, and learn the traffic walking rules of the traffic lights more intuitively and effectively. In particular, the teaching demonstration device can be operated in the living room at home, is not affected by the external weather, and does not need to be set at the traffic light.

[0030] The signal light 2 is connected to the circuit element 7 and the battery pack 8 through wires. The battery pack 8 provides electrical energy. The circuit element 7 mainly includes existing conventional components such as a circuit board, a rectifier, and a frequency converter. The circuit element 7 and the battery pack 8 are both arranged in the internal cavity of the gantry fixing frame 1. The battery pack 8 is connected to the circuit element 7, and the circuit element 7 is electrically connected to the signal light 2.

[0031] In addition to the above, the present application also includes a control switch 5, which can be set at any accessible position on the gantry fixing frame 1. The control switch 5 is electrically connected to the circuit element 7 and can control the switch and color switching of the signal light 2.

[0032] Furthermore, the structure of each gate stopper 3 specifically includes a connecting rod 302 and a torsion spring 303. One end of the connecting rod 302 is vertically hinged on the crossbeam 102, and the other end is connected to the baffle 301. The connecting rod 302 is connected to the driving component, and the connection position between the driving component and the connecting rod 302 is arranged close to one end of the baffle 301, so that it is easier to drive the gate baffle 301 to rotate. The torsion spring 303 is arranged at the hinged end of the connecting rod 302, and is connected between the hinged end of the connecting rod 302 and the column 101. The elastic force of the torsion spring 303 makes the connecting rod 302 always perpendicular to the column 101. Only when the driving component drives the connecting rod 302 to rotate can it overcome the elastic force of the torsion spring 303 so that the connecting rod 302 baffle 301 is parallel to the column 101.

[0033] Furthermore, in one embodiment, the driving component is a pull rope 4, one end of which is connected to the connecting rod 302, and the other end is passed through the column 101. When the connecting rod 302 and the baffle 301 need to be rotated 90° to make the baffle 301 parallel to the column 101, the pull rope 4 can be pulled.

[0034] Furthermore, in order to fix the pull rope 4 after being pulled, a fixing pin 6 is provided on the column 101 , and one end of the pull rope 4 passing through the crossbeam 102 is tied to the fixing pin 6 .

[0035] Alternatively, the fixing pin 6 can also be replaced by a manual wire roller, which can directly pull the connecting rod 302 and the baffle 301 by rotating the wire roller, and the wire roller can directly fix the pull rope 4 through the ratchet locking.

[0036] Furthermore, in the present embodiment, three control switches 5 and three signal lights 2 are provided respectively, and the three control switches 5 are connected to the circuit elements 7 respectively, and the three control switches 5 are connected to the three signal lights 2 correspondingly. Generally, this method has strong operability, and the circuit control and circuit board connection are also simple.

[0037] Furthermore, the gantry fixing frame 1 and the gate stopper 3 are respectively made of plastic material, which is light in weight. Especially in teaching demonstrations to young children at home, its light weight also means high safety. When it accidentally falls over, it will basically not hurt people.

[0038] Furthermore, the circuit elements 7 and battery pack 8 are arranged inside the column 101 and close to the bottom of the column 101. Setting them inside the column 101 can protect the internal circuit elements 7 and battery pack 8, and setting them close to the bottom can lower the center of gravity of the entire demonstration device, making it more stable.

[0039] Furthermore, the two upright posts 101 and the crossbeam 102 are connected by a snap-fit ​​connection, which is convenient for disassembly and installation. Meanwhile, the teaching demonstration device is configured as a detachably connected split structure, which is convenient for transportation and handling.

[0040] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0041] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
