Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency machines, in particular to an automatic switching belt self-locking device for high frequencies. Background Art

[0002] This device is used for high-frequency heating. The high-voltage circuit is controlled by the low-voltage circuit through the high-voltage circuit. The high-voltage output on the left or on the right is controlled by the switching of the device. The working principle of the high-frequency machine is based on the principle of induction heating. When a conductor (usually metal) is placed in a high-frequency electromagnetic field, an induced current will be generated. These induced currents will generate damping loss inside the conductor, thereby generating heat and heating the conductor. This method is often used to heat metal rods, pipes, steel plates, etc.

[0003] The existing dual-output high-frequency automatic switch does not have a self-locking function, which is prone to misoperation. If the solenoid valves on both sides are energized at the same time, high-frequency outputs will appear on both sides, leading to unnecessary safety accidents. Therefore, a high-frequency automatic switch with a self-locking device is proposed to solve the above problem. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 2 The utility model provides an embodiment: a high-frequency automatic switching belt self-locking device, including a sheet metal frame 1, the sheet metal frame 1 is a U-shaped frame, the sheet metal frame 1 is simple and practical in shape and can provide stable support for components, the top inner wall of the sheet metal frame 1 is fixedly connected with a self-locking bracket 2, the design of this self-locking bracket 2 is to ensure the stability of the device during use and avoid misoperation due to external factors, the top of the self-locking bracket 2 is rotatably connected with a swing arm 4, and the left end of the swing arm 4 is rotatably connected with a left joint 3.

[0023] The right end of the swing arm 4 is rotatably connected to the right joint 5. When the swing arm 4 drives the left joint 3 to move downward, the right joint 5 will move upward. Conversely, when the swing arm 4 drives the right joint 5 to move downward, the left joint 3 will move upward. The inner walls on both sides of the bottom of the self-locking bracket 2 are slidably connected to the electromagnetic drive mechanism 6. The existence of this electromagnetic drive mechanism 6 enables the swing arm 4 to rotate accurately under the action of electromagnetic force. The front end of the sheet metal frame 1 is fixedly connected to the sensor bracket 7. The right end of the sensor bracket 7 is fixedly connected to the micro switch 8. The right joint 5 is in contact with the micro switch 8. The rotation of the right joint 5 is controlled by the rotation of the swing arm 4 so that the micro switch 8 controls the device.

[0024] refer to Figure 3-Figure 5The four corners of the bottom of the sheet metal frame 1 are fixedly connected with a high-voltage switching component 9, the bottom of the left joint 3 is rotatably connected to the top of one of the electromagnetic drive mechanisms 6, and the bottom of the right joint 5 is rotatably connected to the top of another electromagnetic drive mechanism 6. The rotation of the left joint 3 and the right joint 5 can drive the electromagnetic drive mechanism 6 to move. The high-voltage switching component 9 includes a plurality of universal resin insulating rods 903, and the tops of the plurality of universal resin insulating rods 903 are fixedly connected to the bottom of the sheet metal frame 1. The bottoms of the two universal resin insulating rods 903 on the left are fixedly connected with a left output copper plate 905, and the bottoms of the two universal resin insulating rods 903 on the right are fixedly connected with a right output copper plate 908. The design of the left output copper plate 905 and the right output copper plate 908 is to realize the output of current, thereby ensuring the normal operation of the device.

[0025] A clamping aluminum sheet 904 is fixedly connected to the top left end of the left output copper plate 905, and another clamping aluminum sheet 904 is fixedly connected to the top right end of the right output copper plate 908. The design of the clamping aluminum sheet 904 is to achieve stable output of current and avoid affecting the operation of the device due to current fluctuations. A movable resin insulating rod 901 is fixedly connected to the bottom of the electromagnetic drive mechanism 6. The function of the movable resin insulating rod 901 and the universal resin insulating rod 903 is to prevent current leakage and ensure that the current can only flow along a predetermined path, thereby improving the safety and stability of the device. A compression spring 902 is fixedly connected to the bottom of the movable resin insulating rod 901, and a switching copper sheet 906 is fixedly connected to the bottom of the compression spring 902. These designs enable the electromagnetic drive mechanism 6 to move precisely under the action of electromagnetic force, thereby achieving precise switching of the current. The bottoms of multiple universal resin insulating rods 903 in the middle are fixedly connected to an input copper plate 907. The design of the input copper plate 907 is to achieve current input, thereby ensuring the normal operation of the device.

[0026] Working principle: First, all operations start with the input copper plate 907, which is the power input interface of the entire device. When the external power supply is connected, the current passes through the input copper plate 907 and enters the inside of the device. Due to the excellent conductivity of copper, the current can pass through the copper plate smoothly, and the corrosion resistance of copper also ensures that the input performance can be maintained stably in various environments. After the current passes through the input copper plate 907, it will be distributed to the two electromagnetic drive mechanisms 6. These two electromagnetic drive mechanisms 6 are located on both sides of the bottom of the self-locking bracket 2. They drive the swing arm 4 to rotate through electromagnetic force. The left and right ends of the swing arm 4 are respectively connected to the left joint 3 and the right joint 5. These two joints enable the swing arm 4 to rotate flexibly under the action of the electromagnetic drive mechanism 6. When the current enters the electromagnetic drive mechanism 6, the electromagnetic force will cause the movable resin insulating rod 901 to rise, thereby driving the compression spring 902 and the switching copper sheet 906. Move upward. During this process, the switching copper plate 906 will contact the left output copper plate 905 or the right output copper plate 908, thereby switching the current from the input copper plate 907 to the output copper plate. At the same time, the microswitch 8, as the control part of the device, will control the working state of the electromagnetic drive mechanism 6 according to the right joint 5, so as to realize precise control of the current switching. When the current output needs to be switched, only the right joint 5 needs to operate the microswitch 8 to control the electromagnetic drive mechanism 6, so that the switching copper plate 906 contacts the left output copper plate 905 or the right output copper plate 908, thereby realizing the switching of the current. During the whole process, the existence of the self-locking bracket 2 ensures the stability of the device. Whether in the process of current input, switching or output, the self-locking bracket 2 can ensure the stability of the device and avoid misoperation or malfunction caused by external factors, thereby achieving efficient, stable and safe working results.
