Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power tool technology, specifically relating to a dual-mode switch locking mechanism for an angle grinder. Background Technology
[0002] An angle grinder is a handheld power tool that uses a high-speed rotating grinding wheel or cutting disc for grinding, cutting, and polishing. It is widely used in metal, stone, and wood processing. Its characteristics include high speed and flexible operation, making it commonly used in construction, decoration, and industrial maintenance. Safety precautions must be taken when using it to avoid injury from sparks and fragments.
[0003] Conventional switch-locking mechanisms can achieve one of two functions: first, a safety function, where releasing the lock button allows the power tool to operate when the switch is gripped; otherwise, the switch cannot be pressed. Second, a normally open function, where gripping the switch allows the power tool to operate, and pressing the lock button locks the switch, preventing manual operation and ensuring the power tool remains continuously powered. Different switch-locking mechanisms are installed to achieve one of these functions depending on the specific requirements. This necessitates designing two sets of molds for production, increasing mold-making costs. Utility Model Content

[0011] As a preferred embodiment of this utility model, an anti-detachment block is fixedly installed on the surface of the blocking block, and the anti-detachment block is used to prevent the jamming block and the blocking block from separating.

[0023] 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.
[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0025] Example
[0026] Reference Figure 1-5 This embodiment of the present invention provides a dual-mode switch locking mechanism for an angle grinder, comprising:
[0027] The handle mechanism 100 includes a mounting housing 110, two spliced housings 120 disposed at the bottom of the mounting housing 110 and spliced together, and a switch 130 hinged between the two spliced housings 120.
[0028] The locking mechanism 200 includes a locking component 210 disposed on the splicing housing 120 and used for dual-mode locking of the switch 130.
[0029] The locking component 210 is used to lock the switch component 130 in two modes, which solves the problem that the traditional locking component 210 can only perform one function, either safety or normally open. This achieves the effect that the locking component 210 can be used for both purposes, requiring only one mold and reducing mold opening costs.
[0030] Specifically, the switch 130 includes a push switch 131 hinged between two spliced housings 120, a protrusion 132 fixedly installed on the top of the push switch 131, and a locking block 133 fixedly installed on the end of the protrusion 132.
[0031] Furthermore, the locking component 210 includes a cylindrical rod 211 slidably mounted on the splicing housing 120, a blocking block 212 fixedly mounted on the surface of the cylindrical rod 211 and used in conjunction with the locking block 133, and a groove 213 formed on the surface of the blocking block 212 and used in conjunction with the protrusion 132.
[0032] Preferably, an anti-detachment block 214 is fixedly installed on the surface of the blocking block 212, the anti-detachment block 214 being used to prevent the jamming block 133 and the blocking block 212 from detaching.
[0033] Among them, the anti-detachment block 214 is used to lock the surface of the locking block 133, thereby improving the locking stability between the blocking block 212 and the locking block 133.
[0034] Furthermore, a limiting plate 215 is fixedly installed on the bottom of the surface of the locking component 210, and a limiting track 160 is fixedly installed on the inner side of the splicing housing 120 to limit the movement of the cylindrical rod 211 in conjunction with the limiting plate 215.
[0035] The limiting plate 215 and the limiting track 160 are used to limit the cylindrical rod 211, improve the stability of the cylindrical rod 211 when sliding, and thus ensure that the blocking block 212 is accurately engaged with one side of the blocking block 133.
[0036] Furthermore, a pressing block 140 is fixedly installed on the surface of the pressing switch 131, and a power switch 150 for use with the pressing block 140 is fixedly installed on the inner side of the splicing housing 120.
[0037] When in use, without pressing the push switch 131, pressing the cylindrical rod 211 causes the cylindrical rod 211 to move the blocking block 212 into the splicing housing 120, and the blocking block 212 is engaged with the inclined surface of the locking block 133. At this time, the protruding plate 132 and the locking block 133 are blocked and limited, and cannot press the push switch 131. As a result, the push block 140 cannot press the power switch 150 to start the angle grinder, which serves as a safety measure.
[0038] When the push switch 131 is pressed, the push switch 131 drives the push block 140 to install the power switch 150, thereby starting the angle grinder. Keeping the push switch 131 pressed, the cylindrical rod 211 is pressed, and the cylindrical rod 211 drives the blocking block 212 to move, so that the blocking block 212 is engaged with one side of the locking block 133. The anti-disengagement block 214 is engaged with the surface of the locking block 133, and the protrusion 132 is located inside the groove 213. When the push switch 131 is released again, since the locking block 133 is engaged by the blocking block 212, the push switch 131 cannot rebound, and the push block 140 is in the state of pressing the power switch 150. There is no need to manually keep the push action to keep the angle grinder continuously powered.
[0039] In summary, by using the locking component 210 to provide dual-mode locking for the switch component 130, the problem of the traditional locking component 210 being able to perform only one function, either a safety lock or a normally open lock, is solved. This achieves the dual-purpose effect of the locking component 210, requiring only one mold and reducing mold opening costs.
