[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker tester with an auxiliary clamping structure. Background Art

[0002] Circuit breakers are common air switches in daily life. Their function is to provide insurance for circuits. When the circuit exceeds the rated value, it will trip and cut off the circuit connection. This protection structure needs to be performance tested before leaving the factory to ensure that it functions normally and will not cause dangerous accidents. Since circuit breakers are small in structure and have different shapes, it is extremely difficult to fix and install them and connect the detection instruments when testing them. Therefore, a circuit breaker tester with an auxiliary clamping structure is required.

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figure 1 to Figure 6 As shown, a circuit breaker tester with an auxiliary clamping structure includes a fixing component, a circuit breaker 5 and a detection meter 6. The fixing component includes a bearing plate 1, a push rod 2, a pressure rod 3 and a positioning pin 4. The fixing component clamps the circuit breaker 5. The detection meter 6 is arranged beside the fixing component and connected to the circuit breaker 5. The bearing plate 1 is placed flat on the ground and holds up the entire circuit breaker 5. The push rod 2 is arranged on the bearing plate 1 and squeezes one side of the circuit breaker 5. The pressure rod 3 is arranged on the bearing plate 1 and is squeezed by the circuit breaker 5. The positioning pin 4 is inserted into the bearing plate 1 and assists in fixing the circuit breaker 5.

[0026] The device clamps the circuit breaker 5 through a fixing component, and performs pressure detection on the circuit breaker 5 through a detection table 6. The bearing plate 1 is used to install a push rod 2, a pressure rod 3 and a positioning pin 4. Since the circuit breaker 5 is a rectangular structure, a spiral push rod 2 is used to fix its long side. There are multiple push rods 2, and their own spacing can be adjusted according to the length of the circuit breaker 5. The wide side is fixed with a pressure rod 3 with a spring 33 structure. The number of pressure rods 3 is single, and the contact angle can be adjusted according to the inclined side of the circuit breaker 5. The positioning pin 4 is used to fix the remaining two sides of the circuit breaker 5, so that the circuit breaker 5 is firmly installed on the bearing plate 1.

[0027] See also Figure 1-2 As shown, the bearing plate 1 includes positioning holes 11, slide grooves 12 and a transverse plate 13. The positioning holes 11 are arranged in an array on the bearing plate 1, the slide grooves 12 are arranged at the edge of the bearing plate 1, and the transverse plate 13 is vertically installed on the side of the bearing plate 1.

[0028] The positioning hole 11 is used to install the latch, the slide groove 12 is used to install the top rod 2, and the cross plate 13 is used to install the pressure rod 3. The latch is selected according to the specific size of the circuit breaker 5 and can be quickly installed and disassembled on the supporting plate 1, which is convenient for replacing the circuit breaker 5 to be tested.

[0029] See also Figure 1 to Figure 3 As shown, the top rod 2 includes a first gasket 21, a mounting frame 22 and a pulley 23. The first gasket 21 is arranged at the top end of the top rod 2 and contacts the circuit breaker 5. The mounting frame 22 is arranged below the top rod 2, and the pulley 23 is arranged at the bottom of the mounting frame 22.

[0030] The first gasket 21 is used to reduce the friction between the circuit breaker 5 and the top rod 2 to increase the service life of the parts. The mounting frame 22 is located in the slide groove 12 on the bearing plate 1 and is displaced in the slide groove 12 through the pulley 23 to adjust the distance between the two top rods 2 and more conveniently fix the side of the circuit breaker 5.

[0031] See also Figure 3 As shown, the first gasket 21 includes a screw rod 211 and a steering sleeve 212 . One end of the screw rod 211 is connected to the top rod 2 . The steering sleeve 212 is rotatably mounted on the screw rod 211 and connected to the first gasket 21 .

[0032] The steering sleeve 212 is used to install the first gasket 21. Rotating the steering sleeve 212 on the screw 211 can control the displacement degree of the first gasket 21 on the top rod 2, and at the same time control the contact and separation state of the first gasket 21 and the circuit breaker 5, ensuring that the top rod 2 can adapt to circuit breakers 5 of various shapes.

[0033] See also Figure 1 to Figure 4As shown, the pressure rod 3 includes a second gasket 31, a convex ring 32 and a spring 33. The second gasket 31 is arranged at the top end of the top rod 2 and contacts the circuit breaker 5. The convex ring 32 is arranged on the outside of the pressure rod 3. The spring 33 is arranged on the convex ring 32 and surrounds the pressure rod 3.

[0034] The second gasket 31 is used to reduce the friction between the circuit breaker 5 and the pressure rod 3 to increase the service life of the parts. The convex ring 32 is used to position the installation of the spring 33. The pressure rod 3 is squeezed by the circuit breaker 5. The spring 33 is in a compressed state and provides a force for the pressure rod 3 to squeeze the circuit breaker 5. The side of the circuit breaker 5 can be fixed in cooperation with the latch.

[0035] See also Figure 4 As shown, the second gasket 31 includes a universal shell 311 and a ball joint 312 . The ball joint 312 is installed on the top of the pressure rod 3 . The universal shell 311 is arranged at the bottom of the second gasket 31 and is rotatably connected to the ball joint 312 .

[0036] Since various circuit breakers 5 have different shapes and may have oblique edges, the second gasket 31 can support the side of the circuit breaker 5 at any angle through the contact between the universal housing 311 and the ball joint 312 .

[0037] See also Figure 1 to Figure 5 As shown, the circuit breaker 5 includes a rotation key 51, a socket 52 and a ventilation groove 53. The rotation key 51 is arranged on the side of the circuit breaker 5, the socket 52 is arranged on both sides of the circuit breaker 5, and the ventilation groove 53 is arranged on the other side of the circuit breaker 5 opposite to the rotation key 51.

[0038] The rotary key 51 is used to control the opening and tripping of the circuit, and the jack 52 is used to connect the detection meter 6 to ensure the connectivity of the circuit. When the circuit breaker 5 trips, safety gas will be generated, and the air-permeable groove 53 is required to balance the air pressure to prevent the air pressure from expanding and damaging the fixed components.

[0039] See also Figure 1 to Figure 6 As shown, the test meter 6 includes a plug wire 61, a display 62 and a knob 63. One end of the plug wire 61 is connected to the test meter 6, and the other end is connected to the circuit breaker 5. The display 62 is arranged in the middle of the test meter 6, and the knob 63 is arranged in the lower part of the test meter 6.

[0040] The plug wire 61 is inserted into the socket 52 of the circuit breaker 5, the display 62 is used to display the measured value, and the knob 63 is used to switch the test mode of current and voltage, thereby improving the practical function of the detection meter 6.

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
