Description

Technical Field

[0001] This utility model relates to a polishing machine, and more particularly to a polishing machine with a detachable power cord. Background Technology

[0002] Polishing machines, as commonly used surface treatment equipment, are widely used for grinding and polishing workpieces such as metal, wood, and stone. They require stable power supply under high speed and high load. Currently, most polishing machines on the market use an integrated power cord design, with the power cord directly soldered or fixed inside the handle at the rear of the machine via a non-removable interface. While this integrated design ensures continuous power supply, in field operations, the power cord is easily cut or broken by workpieces, tools, or workers due to operational errors, leading to power outages. This not only requires disassembling the machine casing to replace or repair the power cord, but frequent disassembly and assembly also accelerates the aging of internal wiring and interfaces, increasing maintenance costs and downtime. To reduce the maintenance burden caused by power cord damage, some manufacturers have introduced detachable designs that separate the power cord from the main unit, allowing for simple plug-and-play replacement. However, these designs generally lack reliable locking mechanisms. High-frequency vibrations during polishing, workpiece collisions, or operator pulling can easily cause the plug and socket to loosen or completely detach. A power outage not only affects polishing quality and production efficiency but may also cause safety hazards such as workpieces flying out and operators losing their balance due to the sudden cessation of equipment operation, posing serious safety risks to on-site operations. Therefore, there is an urgent need for a polishing machine with a power connection structure that allows for convenient and quick power cord replacement while maintaining reliable locking under high vibration and tensile conditions, in order to ensure a continuous and stable power supply to the equipment and improve operational safety.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views of the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figures 1-5 As shown: This utility model provides a polishing machine with a detachable power cord, including: a main unit 1, a handle 2 located at the rear of the main unit 1, and a power cord detachably connected to it. The handle 2 has a power socket 3 at its end that mates with the power cord plug 4, for establishing an electrical connection between external mains power and the main unit 1.

[0022] The handle 2 is symmetrically assembled from a left handle housing 21 and a right handle housing 22. After assembly, a pair of opposing socket fixing grooves 23 are formed inside the end of the handle (see...). Figure 3 , 5 These two fixing slots 23 are used to insert the side fixing strip 31 of the power socket 3, thereby securely installing the power socket 3 inside the handle 2 and preventing it from rotating or shifting. A locking hole 32 is provided inside the socket 3, facing the plug direction, for receiving the following locking structure.

[0023] The end of the power cord plug 4 matches the insertion part of the socket 3. The outer shell of the plug 4 is provided with an elastic locking member 41, the elastic locking member 41 is provided with a pressing knob 42, the elastic locking member 41 is provided with a locking tongue 43, and the free end of the elastic locking member 41 can pop outward due to the elasticity of the material.

[0024] The working principle of this structure is as follows:

[0025] Insertion and Locking: When the plug 4 is pushed into the socket 3, the locking tongue 43 retracts inward under the guidance of the pressing bevel. After the plug is fully in place, the locking tongue 43 regains its elasticity and springs its tip into the locking hole 32 inside the socket 3, achieving a "click" locking (see...). Figure 5 ).

[0026] Unlocking: To unplug the power cord, the operator simply needs to press the button 42 with their thumb. The button 42 will cause the locking tongue 43 to retract inward and disengage from the locking hole 32. Then the plug 4 can be pulled out of the socket 3 to complete the quick disconnection of the power cord.

[0027] In this embodiment of the invention, the power socket 3 and the handle 2 housing are tightly connected by a fixing groove 23 / fixing strip 31 structure, ensuring that the socket is not easily loosened; the elastic locking component 41 (press knob 42 and locking tongue 43) has a simple and reliable structure, and can maintain a stable connection between the power cord and the main unit under high-frequency vibration, workpiece collision or pulling. At the same time, when the power cord needs to be replaced due to abnormal wear, it can be quickly removed and replaced with a new cord by pressing knob 42 without disassembling the housing, which greatly reduces the difficulty of on-site maintenance and downtime.

[0028] This utility model provides a polishing machine that allows for quick power cord replacement and maintains a reliable locking connection under high-frequency vibration and pulling. It solves the problem that existing detachable power cords are prone to loosening and power loss due to vibration or pulling during use, causing the machine to suddenly stop and posing safety hazards.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no conflict in the mechanism, the features in the embodiments disclosed in the present invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
