[0002] In today's electrical testing laboratories, circuit breakers are a common product. Generally, when conducting batch temperature rise tests and overload tests on circuit breakers, multiple disassembly and assembly are required for testing. The traditional installation method is: first install the circuit breaker on the test frame, then select the specified wire specifications from the wire rack, and then fix one end of the wire to the test power supply and the other end to the circuit breaker before testing. When there are multiple samples, multiple installation and disassembly are required. After the test is completed, the test wires need to be removed and put back on the wire rack. The whole process is cumbersome and inefficient, and cannot meet the needs of convenient and efficient testing. Therefore, there is an urgent need in this technical field for a device that can easily disassemble wires and circuit breakers. Summary of the Invention

[0020] In order to make the present invention more clear and easy to understand, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0021] The utility model provides a guide rail type plastic case circuit breaker mounting frame, such as Figure 1 、 Figure 2As shown, it includes a test frame body 2, a Forma wheel 1 is provided at the bottom of the test frame body 2, and the Forma wheel 1 is a universal wheel for easy movement. The test frame body 2 is made of aluminum; a cross bar 9 is movably connected to the test frame body 2, and the cross bar 9 is made of aluminum. There are two of them, which can move up and down on the test frame body 2, that is, a first slide groove 21 is provided at a vertical position on the test frame body 2, and a second bolt 23 that can slide up and down is provided in the first slide groove 21. The cap end of the second bolt 23 is provided in the first slide groove 21, and the head end of the second bolt 23 passes through the circular hole on the cross bar 9 and is threadedly connected with the second petal handle 22. By rotating the second petal handle 22, tightening is achieved, so that the cross bar 9 is fixed at the required position on the test frame body 2. When the second petal handle 22 is loosened, the cross bar 9 can slide up and down on the test frame body 2. Figure 3 、 Figure 4 As shown; the wire holder 5 is movably connected to the cross bar 9, and the wire holder 5 can move left and right in the cross bar 9; one end of the first bolt 11 passes through the second slide groove 91 in the middle of the cross bar 9 and is threadedly connected to the wire holder 5, and the first petal handle 12 is threadedly connected to the first bolt 11. The first petal handle 12 is arranged between the cross bar 9 and the wire holder 5. By tightening the first petal handle 12, the wire holder 5 and the cross bar 9 can be fixed, and loosening the first petal handle 12 can make the wire holder 5 slide left and right on the cross bar 9.

[0022] Two concave guide rails 6 are movably connected to the test frame body 2. These two concave guide rails 6 can be fixed to the test frame body 2 or moved up and down on the test frame body 2 (the principle of the up and down movement of the concave guide rails 6 on the test frame body 2 is the same as the principle of the up and down movement of the crossbar 9 on the test frame body 2). Convex guide rails 10 are fixed to the upper and lower ends of the guide rail mounting plate 7. These convex guide rails 10 work in conjunction with the concave guide rails 6 to allow the guide rail mounting plate 7 to slide out from the left or right.

[0023] During use, the wire 4 passes through the wire holder 5 and is connected to the molded case circuit breaker 8. By moving the wire holder 5 left and right within the crossbar 9, the wire 4 can be adjusted to connect to molded case circuit breakers 8 of different specifications and models. The molded case circuit breaker 8 is connected to the guide rail mounting plate 7 via screws and can be slid out from the left or right along the guide rail mounting plate 7 to facilitate installation and removal of the molded case circuit breaker 8.

[0024] The concave guide rail 6 is provided with at least one fixing pin hole, and the convex guide rail 10 is also provided with a fixing pin hole at a position corresponding to the fixing pin hole on the concave guide rail 6. When the guide rail mounting plate 7 slides to the specified position, the fixing pin 3 passes through the fixing pin holes on the concave guide rail 6 and the convex guide rail 10, thereby preventing the guide rail mounting plate 7 from sliding. This prevents the guide rail mounting plate 7 from sliding due to vibration during high-current testing.

[0025] The working principle of this utility model is as follows:

[0026] First, select a wire 4 of the corresponding specification and place it into the wire holder 5. Then, fix the molded case circuit breaker 8 to the guide rail mounting plate 7 with bolts. Then, slide the guide rail mounting plate 7 from the left or right side of the test frame body 2 into the concave guide rail 6. Adjust the position of the wire holder 5 left or right, connect the wire 4 to the molded case circuit breaker 8, and then you can start the test.
