Description

Technical Field

[0001] This utility model relates to the field of energy-saving device technology, specifically a general-purpose energy-saving device based on an improved miniature welding machine. Background Technology

[0002] Miniature welding machines typically employ high-frequency inverter technology. When an energy-saving device detects no-load conditions, it cuts off the inverter's power supply, maintaining only low-power operation of the control circuit.

[0003] For example, patent application number 202222998329.4 published on the China Patent Network describes a household energy-saving device, comprising an energy-saving body and an auxiliary power strip. The energy-saving body has a short groove near its upper side, inside which is an energy-saving mounting bracket. A long groove is also present near the rear surface of the energy-saving body. A voltage display screen is embedded near the upper front surface of the energy-saving body. A first-type plug is fixedly installed at the center of the upper surface of the energy-saving body. An independent fuse is fixedly installed near the first-type plug on the upper surface of the energy-saving body. An indicator light is fixedly installed near one corner of the front end of the upper surface of the energy-saving body. A second-type plug is fixedly installed at the center of the upper surface of the auxiliary power strip. This household energy-saving device, with its mounting bracket, facilitates easy installation onto a socket, making installation and removal simple and quick. It is particularly convenient for high-power-consuming appliances.

[0004] However, the existing energy-saving device and equipment have a relatively simple connection method, mainly through plug-in connection. During the operation of the welding machine, mechanical vibration will be generated, and the energy-saving device installed on the surface of the welding machine is easily affected by the vibration, which may cause the cable to fall off.

[0005] Therefore, it is necessary to design and modify the general-purpose energy-saving device based on the improvement of the micro welding machine. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a universal energy-saving device based on an improved micro welding machine. This device has the advantage of improving the stability of cable connections and solves the problem that the connection method between existing energy-saving devices and equipment is relatively simple, mainly through plug-in connection. However, the welding machine generates mechanical vibrations during operation, and the energy-saving device installed on the surface of the welding machine is easily affected by the vibrations, causing the cable to fall off.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a general-purpose energy-saving device based on an improved micro welding machine, comprising a body;

[0008] Cables plugged into both ends of the machine body;

[0009] The four corners of the front of the machine body are movably connected to pressure plates by pins. The side of the pressure plate away from the machine body extends to both ends of the machine body and contacts the surface of the cable. The front of the machine body is provided with a transmission structure, which can control the swing of the pressure plate and squeeze and fix the cable.

[0010] In a preferred embodiment of this utility model, the transmission structure includes a connecting frame fixedly connected to the front of the machine body. A bidirectional screw is movably connected inside the connecting frame via bearings. Both sides of the surface of the bidirectional screw are threaded with sleeves. A sleeve plate is fixedly connected to the side of the pressure plate near the machine body. The side of the sleeve plate away from the pressure plate extends between the sleeve and the machine body. A sliding rod located inside the sleeve plate is fixedly connected to the back of the sleeve. The sliding rod is slidably connected to the sleeve plate. The left end of the bidirectional screw passes through to the left side of the connecting frame and is fixedly connected to a rotating wheel.

[0011] As a preferred embodiment of this utility model, the surface of the connecting frame is set to be hollow, and a limiting block located inside the connecting frame is fixedly connected to the front of the screw sleeve, and the limiting block and the connecting frame are slidably connected.

[0012] As a preferred embodiment of this utility model, upright plates are fixedly connected to both sides of the front of the machine body, and a transmission rod is movably connected inside the upright plate. Support plates are fixedly connected to both ends of the transmission rod, and the side of the support plate away from the transmission rod extends to the outside of the machine body and is flush with the back of the machine body.

[0013] As a preferred embodiment of this invention, helical gears are fixedly connected to both the surface of the transmission rod and the front side of the sleeve plate, and the helical gears mesh with each other.

[0014] As a preferred embodiment of this invention, a damping plate is fixedly connected to the back of the machine body. The damping plate is elastic and its interior is hollow.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The pressure plate of this utility model applies physical clamping force to the cable by swinging. Compared with the traditional plug-in method, it can resist the cable falling off due to the vibration of the welding machine. The pressure plates distributed at the four corners form symmetrical clamping force, avoiding uneven force on a single point, which may cause the cable to deviate or wear locally.

[0017] 2. This utility model uses a bidirectional screw to rotate and drive the two screw sleeves on both sides to move synchronously towards the center or outward, ensuring that the pressure plate applies symmetrical pressure to the cable. The rotary drive enables one-handed operation, simplifying the cable fixing process and eliminating the need for additional tools.

[0018] 3. This utility model reduces the weight of the connecting frame through a hollow structure and promotes the dissipation of heat generated by the friction between the bidirectional screw and the screw sleeve, avoiding structural deformation caused by thermal expansion. The limiting block slides within the connecting frame to constrain the movement trajectory of the screw sleeve and prevent the screw sleeve from deflecting or disengaging when the screw rotates.

[0019] 4. The present invention features a support plate that unfolds and is flush with the back of the machine body, increasing the contact area between the energy-saving device and the welding machine, dispersing vibration energy, and allowing the support plate to rotate and swing with the transmission rod, reducing space occupation when not in operation.

[0020] 5. This utility model utilizes helical gear meshing to directly drive the transmission rod to rotate during the movement of the pressure plate, thereby achieving synchronous operation of cable fixing and support plate unfolding. The helical gear meshing structure avoids the clearance error of traditional linkage mechanisms, ensuring that the unfolding angle of the support plate matches the clamping force of the pressure plate.

[0021] 6. This utility model uses an elastic hollow damping plate fixed to the back of the machine body. The elastic material absorbs high-frequency vibrations, and the hollow structure buffers low-frequency vibrations through deformation, thus isolating the vibrations of the welding machine from being transmitted to the energy-saving device.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 4As shown, the present invention provides a general-purpose energy-saving device based on an improved micro welding machine, comprising a body 1;

[0029] Cables 2 are plugged into both ends of the body 1;

[0030] The four corners of the front of the body 1 are movably connected to pressure plates 3 by pins. The side of the pressure plate 3 away from the body 1 extends to both ends of the body 1 and contacts the surface of the cable 2. The front of the body 1 is provided with a transmission structure 4, which can control the pressure plate 3 to swing and squeeze and fix the cable 2.

[0031] refer to Figure 1 The transmission structure 4 includes a connecting frame 5 fixedly connected to the front of the body 1. A bidirectional screw 6 is movably connected inside the connecting frame 5 via a bearing. Both sides of the surface of the bidirectional screw 6 are threaded with screw sleeves 7. A sleeve plate 8 is fixedly connected to the side of the pressure plate 3 closest to the body 1. The side of the sleeve plate 8 away from the pressure plate 3 extends between the screw sleeve 7 and the body 1. A sliding rod 9 located inside the sleeve plate 8 is fixedly connected to the back of the screw sleeve 7. The sliding rod 9 is slidably connected to the sleeve plate 8. The left end of the bidirectional screw 6 passes through to the left side of the connecting frame 5 and is fixedly connected to a rotating wheel.

[0032] As a technical optimization of this utility model, the rotation of the bidirectional screw 6 drives the two side screw sleeves 7 to move synchronously towards the center or outward, ensuring that the pressure plate 3 applies symmetrical pressure to the cable 2, while the rotary drive enables one-handed operation, simplifying the cable 2 fixing process without the need for additional tools.

[0033] refer to Figure 3 The surface of the connecting frame 5 is set to be hollow, and the front of the screw sleeve 7 is fixedly connected to the limiting block 10 located inside the connecting frame 5. The limiting block 10 and the connecting frame 5 are slidably connected.

[0034] As a technical optimization of this utility model, the weight of the connecting frame 5 is reduced by the hollow structure, and the heat generated by the friction between the bidirectional screw 6 and the screw sleeve 7 is dissipated, avoiding structural deformation caused by thermal expansion. The limiting block 10 slides in the connecting frame 5 to constrain the movement trajectory of the screw sleeve 7 and prevent the screw sleeve 7 from deflecting or coming off when the screw rotates.

[0035] refer to Figure 2 Both sides of the front of the body 1 are fixedly connected to the upright plate 11. The inside of the upright plate 11 is movably connected to the transmission rod 12. Both ends of the transmission rod 12 are fixedly connected to the support plate 13. The side of the support plate 13 away from the transmission rod 12 extends to the outside of the body 1 and is flush with the back of the body 1.

[0036] As a technical optimization of this utility model, the support plate 13 is unfolded and flush with the back of the machine body 1, which increases the contact area between the energy saver and the welding machine and disperses the vibration energy. The support plate 13 can rotate and swing with the transmission rod 12, reducing the space occupation in the non-working state.

[0037] refer to Figure 3 Helical gears 14 are fixedly connected to the surface of the transmission rod 12 and the front of the sleeve plate 8, and the helical gears 14 mesh with each other.

[0038] As a technical optimization of this utility model, when the pressure plate 3 moves, the transmission rod 12 is directly driven to rotate by the meshing of the helical gear 14, so as to realize the synchronous operation of fixing the cable 2 and unfolding the support plate 13. The meshing structure of the helical gear 14 avoids the gap error of the traditional linkage mechanism and ensures that the unfolding angle of the support plate 13 matches the clamping force of the pressure plate 3.

[0039] refer to Figure 2 A damping plate 15 is fixedly connected to the back of the body 1. The damping plate 15 is elastic and the interior of the damping plate 15 is hollow.

[0040] As a technical optimization of this utility model, the elastic hollow damping plate 15 is fixed to the back of the body 1. The elastic material absorbs high-frequency vibration, and the hollow structure buffers low-frequency vibration through deformation, thus isolating the vibration of the welding machine from being transmitted to the energy-saving device.

[0041] The working principle and usage process of this utility model are as follows: After the cable 2 of the energy-saving device is plugged into both ends of the body 1, the operator manually rotates the rotating wheel of the transmission structure 4. The rotating wheel drives the bidirectional screw 6 to rotate, causing the two screw sleeves 7 to move synchronously towards the center or outward along the screw. The movement of the screw sleeves 7 pushes the sleeve plate 8 through the slide rod 9 on the back, forcing the pressure plate 3 to swing inward with the pin as the fulcrum, thereby applying uniform pressure to the surface of the cable 2, realizing the physical fixation of the cable 2 and preventing loosening of the plug. During the movement of the sleeve plate 8, the helical gear 14 on its front meshes with the helical gear 14 on the transmission rod 12, holding the cable 2 in place. The motion is converted into the rotational motion of the transmission rod 12. The transmission rod 12 drives the support plates 13 at both ends to unfold from inside the upright plate 11 outward until the support plates 13 are flush with the back of the machine body 1. The unfolded support plates 13 increase the contact area between the machine body 1 and the welding machine, disperse the mechanical vibration energy, and improve the overall stability. Meanwhile, the elastic damping plate 15 on the back of the machine body 1 absorbs the residual vibration during the operation of the welding machine through the hollow structure and material deformation. The air or elastic filler inside the damping plate 15 consumes the vibration energy through the compression and rebound process, further blocking the vibration from being transmitted to the energy-saving device body, forming double protection.

[0042] In summary, this general-purpose energy-saving device based on the improvement of a micro welding machine uses pressure plate 3 to apply physical clamping force to cable 2 by swinging. Compared with the traditional plug-in method, it can resist the cable 2 from falling off due to the vibration of the welding machine. The pressure plates 3 distributed at the four corners form a symmetrical clamping force, avoiding uneven force at a single point that could cause cable 2 to deflect or wear locally.
