Description

Technical Field

[0001] The utility model relates to the technical field of display devices, in particular to an employment interview training display device. Background Art

[0002] In the electrical employment training courses, teachers will often organize students to conduct teaching demonstrations. Generally, they teach students how to connect electricity, test electricity, troubleshoot and other equipment maintenance content. They need to use a workbench and electrical equipment. The workbench contains a backplane. The electrical equipment is installed on the backplane with screws or other components. The wires used by the electrical equipment are connected to the power supply or other equipment. After power is turned on, the teacher sets up a fault and then demonstrates how to troubleshoot and repair.

[0003] In the process of implementing the solution, the inventors found that the following problems existed in the prior art and have not been well solved: the number of electrical equipment required on the back panel is often two or more, and the number of wires and detection wires required is relatively large, which causes the wires to hang down in a messy manner on the back panel, which not only affects students' observation, but also easily causes safety hazards. Utility Model Content

[0007] Preferably, the extrusion screw passes through the bottom of one end of the rear plate and contacts the top of the workbench.

[0008] Preferably, one end of the side bracket away from the slide frame is fixedly connected to both side walls of the back plate.

[0009] Preferably, the plug posts are respectively inserted into the inside of the plug holes, and the keys are respectively inserted into the inside of the key slots.

[0010] Preferably, the four keyways in the jack are all in a cross shape.

[0011] Preferably, sliding grooves are excavated at the bottom ends of the side grooves that are away from each other, and sliding blocks are slidably connected to the inside of the sliding grooves, and the tops of the sliding blocks are fixedly connected to the slide frames respectively.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The cable tie ring can be installed in the jack and keyway according to the position of the wire and the angle required by the teacher's teaching display without blocking the line of sight, and can be adjusted to a vertical state and a parallel state, so that the wires can be placed horizontally or vertically to achieve the effect of cable arrangement. It not only effectively organizes the wires and fills the line of sight that affects the display, but also can isolate the wires to avoid safety hazards.

[0014] 2. The back panel slides on the slide bar in the side groove through the side bracket and the slide bracket, so that the back panel can be closer to the front end. For small-scale teaching demonstrations, it can not only enable students and teachers to observe carefully, but also enable teachers to more conveniently touch the equipment connected to the back panel during the demonstration, which brings convenience to the teaching demonstration. After the position is adjusted, the extrusion screw at the bottom end of the rear side of the back panel rotates and descends until its bottom contacts the top of the workbench, so that the back panel is limited to the current position by the extrusion screw extruding the workbench.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, a job interview training display device includes a workbench 1, a backboard 2 is provided on the top of the workbench 1, a plurality of plug holes 21 are drilled at the front end of the backboard 2, four key grooves 22 are drilled at the rear end of the backboard 2 located inside the plug holes 21, a cable tie ring 3 is provided at the position of the plug holes 21, a plug column 31 is fixed at the rear end of the cable tie ring 3, a slide groove 32 is drilled at the rear end of the plug column 31, a slider 33 is slidably connected to the inner ends of the slide groove 32, and a connecting plate 34 is fixed to the outer wall of the slider 33 , a key 35 is fixed to the ends of the connecting plates 34 that are away from each other, and tension springs 36 are fixed to the two ends between the connecting plates 34. Side grooves 4 are drilled on the side walls of both sides of the workbench 1, and sliding rods 5 are fixed to the ends close to each other inside the side grooves 4. The outer walls of the sliding rods 5 are slidably connected to sliding racks 6, and the ends of the sliding racks 6 extending to the outside of the workbench 1 are fixed to side brackets 7. Rear plates 10 are fixed to the bottom ends of the rear side walls of the back plate 2, and extrusion screws 11 are threadedly connected to the rear plates 10.

[0023] Specifically, the extrusion screw 11 passes through the bottom of one end of the rear plate 10 and contacts the top of the workbench 1 . After the extrusion screw 11 squeezes the workbench 1 , the back plate 2 can be positioned on the workbench 1 .

[0024] Specifically, one end of the side bracket 7 away from the slide frame 6 is fixedly connected to the side walls of the back plate 2 respectively.

[0025] Specifically, the plug posts 31 are respectively inserted into the inside of the sockets 21, and the keys 35 are respectively inserted into the inside of the key slots 22. The four key slots 22 in the sockets 21 are all in a "cross" shape, so that the keys 35 can be inserted into the left and right, upper and lower key slots 22, thereby achieving the horizontal or vertical limit of the cable tie ring 3.

[0026] Specifically, sliding grooves 8 are excavated at the bottom ends of the side grooves 4 that are away from each other, and sliding blocks 9 are slidably connected inside the sliding grooves 8. The tops of the sliding blocks 9 are fixedly connected to the slide frames 6, respectively, so that the movement of the back panel 2 is more horizontal and stable.

[0027] Working principle: The cable tie ring 3 can be installed in the socket 21 and the key slot 22 according to the position of the wire and the angle required for the teacher's teaching demonstration without blocking the line of sight, and can be adjusted to a vertical state and a parallel state, so that the wires can be placed horizontally or vertically to achieve the effect of cable arrangement. It not only effectively arranges the wires and fills the observation line that affects the display, but also can isolate the wires to avoid safety hazards. The column 31 is inserted into the inside of the socket 21, and the two keys 35 are retracted by the tension spring 36 until the key 35 moves to the position of the key slot 22, and then it can be inserted into the key slot 22 by the tension of the tension spring 36, thereby limiting the cable tie ring 3. The key 35 can be forked horizontally into the left and right key slots 22, or into the upper and lower key slots 22, so as to change the cable tie angle of the cable tie ring 3. The back panel 2 slides on the slide bar 5 in the side slot 4 through the side bracket 7 and the slide bracket 6, so that the back panel 2 can be closer to the front end. For a small-scale teaching display, it can not only enable students and teachers to observe carefully, but also enable the teacher to more conveniently touch the equipment connected to the back panel 2 during the display, which brings convenience to the teaching display. After the adjustment position is completed, the extrusion screw 11 at the bottom end of the rear side of the back panel 2 rotates and descends until its bottom contacts the top of the workbench 1, so that the back panel 2 is limited at the current position by the extrusion screw 11 squeezing the workbench 1.
