Abstract
Description
Technical Field
[0001] This utility model relates to the field of teaching equipment technology, and in particular to a mobile disconnect switch teaching and maintenance device. Background Technology
[0002] A disconnector switch is a switching device mainly used for "isolating power supply, switching operations, and connecting and disconnecting small current circuits" without arc extinguishing function. Electrical training requires teaching and training on the operation and use of disconnectors.
[0003] Currently, the teaching equipment for disconnecting switches fixes the ceramic resistor of the disconnecting switch on the frame. When operating it, students need to adjust the arrangement of the wires. Different circuits require different wires to be connected, and the direction of the wires also varies. Students need to avoid the area where the knife plate on top of the ceramic resistor is connected. However, because the insulation resistor is fixedly installed, it will cause inconvenience to students in actual use. Utility Model Content
[0004] To address the problems in the prior art, this utility model provides a mobile disconnect switch teaching and maintenance device.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0006] A mobile disconnect switch teaching and maintenance device includes a teaching platform cabinet. A side frame is fixed to the top of the teaching platform cabinet near the rear edge. Guide grooves are provided on both inner walls of the side frame. A bridging plate is slidably arranged between the inner walls of the two guide grooves. Pull-out grooves extending into the guide grooves are provided on both sides of the side frame. A support plate is slidably arranged inside the pull-out groove. Two protrusions are fixed on one side of the support plate.
[0007] Optionally, one side of each of the two protrusions extends to the bottom of the bridging plate, and a through-hole is provided on the top of the bridging plate near the protrusion, with the two through-holes extending to the bottom of the bridging plate.
[0008] Optionally, ceramic resistors are provided on the top of the bridge plate near both side edges, and a knife plate is provided between the tops of the two ceramic resistors.
[0009] Optionally, the top of the teaching platform cabinet has two storage slots, the bottom of the teaching platform cabinet is equipped with casters at the four corners, and the rear of the side frame is fixed with a push handle.
[0010] Optionally, a fixing frame is fixed to one side of the side frame, and a push rod is provided on one side of the fixing frame, with one end of the push rod sliding through into the interior of the fixing frame.
[0011] Optionally, a lifting plate is fixed to one end of the push rod, a spring is fixed to one side of the lifting plate, one end of the spring is fixed to the fixing frame, and a handle is fixed to the other end of the push rod.
[0012] Optionally, one side of the lifting plate slides through into the interior of the guide groove and is fixed to one end of the support plate.
[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0014] 1. In the initial state, the lifting plate is pressed into the guide groove by the elastic pressure of the spring, thereby causing the support plate to press into the pull-out groove. At this time, the top of the protrusion on the support plate is in contact with the bottom of the bridge plate, and the protrusion is located on one side of the through opening. At this time, the bridge plate can be limited and fixed by the protrusion.
[0015] 2. In this utility model, when it is necessary to adjust the position of the bridging plate, the lifting plate is slid outward by pulling the handle to the outside of the side frame, thereby driving the support plate to slide to one side of the pull-out groove. When the protrusion slides to the bottom of the through opening, the bridging plate can be released. Then, the bridging plate can be slid up and down inside the guide groove to change the position of the ceramic resistor and the knife plate inside the side frame. Attached Figure Description

Detailed Implementation
[0024] The present invention will now be described in further detail with reference to the accompanying drawings.
[0025] Example 1, as Figure 1-4 As shown, this utility model provides a technical solution for a mobile disconnect switch teaching and maintenance device: it includes a teaching platform cabinet 1, a side frame 3 fixed at the top of the teaching platform cabinet 1 near the rear edge, guide grooves 6 are provided on both inner walls of the side frame 3, a bridging plate 7 is slidably arranged between the inner walls of the two guide grooves 6, and a pull-out groove 12 extending into the guide groove 6 is provided on both sides of the side frame 3, a support plate 10 is slidably arranged inside the pull-out groove 12, and two protrusions 11 are fixed on one side of the support plate 10.
[0026] The effect achieved by the entire embodiment 1 is that, in the initial state, the elastic pressure of the spring 17 presses the lifting plate 14 into the guide groove 6, thereby causing the support plate 10 to be pressed into the pull-out groove 12. At this time, the top of the protrusion 11 on the support plate 10 is in contact with the bottom of the bridge plate 7, and the protrusion 11 is located on one side of the through opening 13. At this time, the bridge plate 7 can be limited and fixed by the protrusion 11.
[0027] Example 2, as Figure 1-4As shown, one side of each of the two protrusions 11 extends to the bottom of the bridging plate 7. The top of the bridging plate 7 near the protrusions 11 is provided with through openings 13. The two through openings 13 extend to the bottom of the bridging plate 7. Ceramic resistors 8 are provided on the top of the bridging plate 7 near the two side edges. A knife plate 9 is provided between the tops of the two ceramic resistors 8. The top of the teaching platform cabinet 1 has two storage slots 5. The bottom of the teaching platform cabinet 1 is provided with casters 2 at the four corners. A push handle 4 is fixed to the rear side of the side frame 3. A fixing frame 15 is fixed to one side of the side frame 3. A push rod 16 is provided on one side of the fixing frame 15. One end of the push rod 16 slides through the interior of the fixing frame 15. A lifting plate 14 is fixed to one end of the push rod 16. A spring 17 is fixed to one side of the lifting plate 14. One end of the spring 17 is fixed to the fixing frame 15. A handle 18 is fixed to the other end of the push rod 16. One side of the lifting plate 14 slides through the interior of the guide groove 6 and is fixed to one end of the support plate 10.
[0028] The effect achieved by the entire embodiment 2 is that when it is necessary to adjust the position of the bridging plate 7, by pulling the handle 18 to the outside of the side frame 3, the lifting plate 14 slides to the outside of the side frame 3, thereby driving the support plate 10 to slide to one side of the pull-out groove 12. When the protrusion 11 slides to the bottom of the through opening 13, the limitation on the bridging plate 7 can be released. Then, the bridging plate 7 can be slid up and down inside the guide groove 6 to change the position of the ceramic resistor 8 and the knife plate 9 inside the side frame 3.
[0029] Working principle: In the initial state, the elastic pressure of the spring 17 presses the lifting plate 14 into the guide groove 6, thereby causing the support plate 10 to be pressed into the pull-out groove 12. At this time, the top of the protrusion 11 on the support plate 10 is in contact with the bottom of the bridge plate 7, and the protrusion 11 is located on one side of the through opening 13. At this time, the bridge plate 7 can be limited and fixed by the protrusion 11. When it is necessary to adjust the position of the bridge plate 7, the handle 18 is pulled outward of the side frame 3, thereby causing the lifting plate 14 to slide outward of the side frame 3, and then causing the support plate 10 to slide to one side of the pull-out groove 12. When the protrusion 11 slides to the bottom of the through opening 13, the limitation on the bridge plate 7 can be released. Then, the bridge plate 7 can be slid up and down inside the guide groove 6 to change the position of the ceramic resistor 8 and the knife plate 9 inside the side frame 3.
