Description

Technical Field

[0001] The utility model belongs to the technical field of circuit breaker auxiliary components, and particularly relates to a sensor fixing device for a circuit breaker. Background Art

[0002] A circuit breaker is a switch device that can close, carry and disconnect current under normal circuit conditions and close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. As the scale of the power grid expands year by year, the mechanical characteristics of the circuit breaker must be tested when the circuit breaker is handed over and overhauled.

[0003] The circuit breaker sensor cannot be quickly positioned and fixed before installation, making the installation difficult and inconvenient to operate. Improper installation during the installation process may also be dangerous and cause injuries to workers, which may also cause sensor failure or even damage. Utility Model Content

[0004] The purpose of the utility model is to provide a sensor fixing device for a circuit breaker, which starts a motor to rotate a bidirectional threaded rod and drives two moving blocks to move in relative directions. The movement of the moving block drives the clamping claws to move synchronously so that they can clamp the installed sensor, thereby solving the problems of low efficiency of existing disassembly and assembly, inconvenience in use, and inability to quickly position and fix the sensor before installation, which makes it dangerous if the installation is improperly performed during the installation process, thereby causing sensor failure or even damage.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a sensor fixing device for a circuit breaker, comprising a bottom plate, a top block fixedly connected to the front of the bottom plate, a rubber block 1 fixedly connected to the bottom of the top block, a limiting block 1 fixedly connected to the side of the bottom plate near the top block, a base is arranged on the front of the bottom plate, a motor 1 is fixedly connected to the front of the base, a bidirectional threaded rod is fixedly connected to the right output end of the motor 1, a moving block 1 is threadedly connected to the left and right sides of the outer surface of the bidirectional threaded rod, and clamps are fixedly connected to the tops of the two moving blocks 1. The utility model arranges the moving block 1, specifically, starts the motor 1 to rotate the bidirectional threaded rod, and drives the two moving blocks 1 to move in relative directions at the same time. The movement of the moving block 1 drives the clamps to move synchronously so that they can clamp the installed sensor, so that the device can be quickly positioned and fixed before installation, and the equipment can be quickly disassembled, which greatly increases the convenience of equipment disassembly and improves work efficiency.

[0007] Furthermore, a limiting plate is fixedly connected to the front side of the clamp, and the limiting plate is arranged in an arc shape. A rubber sheet 2 is fixedly connected to the right side of the clamp located on the left side. A storage plate is fixedly connected to the front side of the base close to the bidirectional threaded rod. Sliding grooves are provided at the bottom of the two moving blocks 1. The opening of the sliding groove enables the moving block 1 to move stably on the slide rail without deviating from the track.

[0008] Furthermore, a fixed block 1 is rotatably connected at the center of the outer surface of the bidirectional threaded rod, and slide rails are fixedly connected to the left and right sides of the fixed block 1. The right side of the bidirectional threaded rod is rotatably connected to a fixed plate. The setting of the fixed block restricts the bidirectional threaded rod from rotating inside it, so that it can be limited and rotate stably.

[0009] Furthermore, a motor 2 is fixedly connected to the front side of the base plate, screws are threadedly connected to the four corners of the front side of the base plate, slideways are fixedly connected to the left and right sides of the base plate, sliders are slidably connected inside the two slides, the right side of the slider on the left side is fixedly connected to the left side of the moving block 2, and the left side of the slider on the right side is fixedly connected to the right side of the moving block 2. The arrangement of the slideway and the slider can reduce the pressure exerted by the moving block 2 on the transmission belt, so that the transmission belt can be used longer, thereby extending the life of the equipment.

[0010] Furthermore, the output end on the back side of the motor 2 is fixedly connected to a rotating shaft 1, the outer surface of the rotating shaft 1 is transmission-connected to a transmission belt, the back side of the base plate is rotatably connected to a rotating shaft 2, and the rotating shaft 1 is transmission-connected to the rotating shaft 2 through a transmission belt. The setting of the transmission belt can enable the rotating shaft 1 to drive the rotating shaft 2 to move synchronously when it moves.

[0011] Furthermore, the bottom of the limiting block 1 is fixedly connected to the top of the slide, and the back of the base is fixedly connected to the front of the moving block 2. The setting of the limiting block 1 prevents the device from leaving the slide when moving, making the device safer when in use.

[0012] Furthermore, the interior of the movable block 2 is fixedly connected to the outer surface of the transmission belt, the bottom of the limiting block 2 located above is in contact with the top of the movable block 2, and the top of the limiting block 2 located below is in contact with the bottom of the movable block 2. The setting of the limiting block 2 enables the transmission belt to simultaneously drive the movable block 2 to move synchronously when it moves.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets a moving block 1, specifically, starts a motor 1 to rotate the bidirectional threaded rod, and at the same time drives the two moving blocks 1 to move in relative directions. The movement of the moving block 1 drives the clamping claws to move synchronously so that they can clamp the installed sensor, so that the device can be quickly positioned and fixed before installation, and the equipment can be quickly disassembled, which greatly increases the convenience of equipment disassembly and improves work efficiency.

[0015] 2. The utility model sets a rotating shaft 1, specifically, starts a motor 2 to rotate the rotating shaft 1, and at the same time makes the rotating shaft 2 connected by the transmission rotate synchronously to make the limiting block 2 slide under the restriction of the slideway, so that the device can be lifted after the installation is completed and fixed, so that the device can be lifted and will not be easily touched to cause danger, thereby increasing the safety of the equipment.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
