Description

Technical Field

[0001] This utility model relates to the field of angle grinder technology, and in particular to an adjustable grip electric angle grinder housing. Background Technology

[0002] An electric angle grinder is an abrasive tool used for cutting and polishing fiberglass. The machine can be equipped with a variety of working heads, such as coarse grinding wheels, fine grinding wheels, polishing wheels, rubber wheels, cutting wheels, and wire wheels. The electric angle grinder uses high-speed rotating thin grinding wheels, as well as rubber grinding wheels and wire wheels, to grind, cut, remove rust, and polish metal components.

This utility model includes an electric grinder and a housing. A locking block is fixedly connected to one side of the housing. The locking block has a square hole inside, and arc-shaped grooves are formed on both its upper and lower surfaces. A sliding plate is slidably disposed inside the arc-shaped grooves, and a threaded through hole is formed on the surface of the sliding plate. This utility model, by setting up the electric grinder, housing, and locking block, allows for fixing by first pressing a pressure plate. The pressure plate slides by engaging with the teeth on a toothed rod, pushing the toothed rod backward against the spring. Then, the handle is twisted to screw the handle into the threaded through hole in the sliding plate. After releasing the pressure plate, the toothed rod is pushed back to its original position by the spring, causing the square rod and square hole to engage, thus installing the handle.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1: Reference Figure 1-5The diagram shows an adjustable grip electric angle grinder housing, including a housing 1. The housing 1 serves as the main support structure of the angle grinder, housing internal core components such as the motor. An adjustable connecting assembly is provided on its outer side. This assembly enables a detachable connection and position adjustment between the handle 2 and the housing 1. The handle 2, located on the outer side of the housing 1, provides a grip for the user to easily operate the angle grinder. Multiple grooves 12 are formed on the outer side of the housing 1, providing insertion space for an elastic steel plate 4 to initially position the handle 2. A pair of slots 13 are formed on the inner side of the grooves 12, engaging with a locking block 8. The elastic steel plate 4 can be clamped and fixed to prevent the handle 2 from falling off during use. A pair of elastic steel plates 4 that are adapted to the groove 12 are fixedly connected to the outside of the handle 2. The elastic steel plate 4 has elastic deformation capability and can bend under force, which facilitates the disengagement of the locking block 8 or its insertion into the slot 13. The locking block 8 that is adapted to the slot 13 is fixedly connected to the outside of the elastic steel plate 4. After the locking block 8 is inserted into the slot 13, it can enhance the stability of the connection between the handle 2 and the housing 1. A rotating rod 6 is rotatably connected to the outside of the handle 2. The rotating rod 6 can drive the traction rope 5 to move by rotating, thereby controlling the deformation of the elastic steel plate 4. A pair of traction ropes 5 are fixedly connected to the outside of the rotating rod 6 for traction. Rope 5 is used to transmit the force of the rotating rod 6, causing the elastic steel plate 4 to generate an inward pulling force and disengage from the slot 13. The end of the traction rope 5 away from the rotating rod 6 is fixedly connected to the elastic steel plate 4. A reinforcing limiting component is provided on the outside of the rotating rod 6 to limit the rotation of the rotating rod 6 and ensure that the position of the handle 2 remains stable after adjustment. The reinforcing limiting component includes a screw 7 fixedly connected to one end of the rotating rod 6. The screw 7 can fix the position of the rotating rod 6 by cooperating with the threaded hole 14. The outside of the handle 2 is provided with a threaded hole 14, which provides a threaded connection point for the screw 7. The screw 7 and the threaded hole 14 are adapted to each other, and after they are tightened, they can prevent... If the rotating rod 6 rotates unexpectedly, it ensures that the traction rope 5 remains stable. A plug rod 3 is fixedly connected to the outside of the handle 2. The plug rod 3 enhances the guidance of the connection between the handle 2 and the housing 1, preventing the handle 2 from shifting during installation. A pressing block 9 is fixedly connected to the end of the plug rod 3 away from the handle 2. The pressing block 9 is made of elastic material. After being inserted into the slot 15, it can generate friction through compression, further improving the firmness of the connection between the handle 2 and the housing 1. A slot 15 is opened on the outside of the housing 1. The slot 15 provides installation space for the plug rod 3 and the pressing block 9. The plug rod 3, the pressing block 9 and the slot 15 are compatible. The three of them work together to help position the handle 2 and reduce shaking during use.

[0024] Example 2: Reference Figure 1-5Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a pressure sensor 10 adapted to the extrusion block 9 is provided on the inner wall side of the slot 15. The pressure sensor 10 can monitor the pressure applied by the extrusion block 9 in real time and provide data feedback on the equipment's operating status. An anti-slip ring 11 is fixedly connected to the outer side of the rotating rod 6. The anti-slip ring 11 can increase the friction between the hand and the rotating rod 6, making it easier to hold and operate stably. A rubber pad is provided on the outer side of the elastic steel plate 4. The rubber pad can enhance the sealing between the elastic steel plate 4 and the contact parts, and at the same time play a role in buffering and shock absorption. The inner wall side of the groove 12 is coated with a solvent-based polyurethane resin coating. This coating can improve the wear resistance and corrosion resistance of the inner wall of the groove 12 and extend its service life.

[0025] The working principle of this utility model is as follows: Dragging the handle 2 causes a pair of elastic steel plates 4 to extend into the groove 12, while dragging the rotating rod 6 and screw 7 to align with the threaded hole 14. Dragging the anti-slip ring 11 causes the rotating rod 6 and screw 7 to rotate, making the screw 7 threadedly connected to the threaded hole 14. As the screw 7 extends into the threaded hole 14, the rotating rod 6 releases the traction rope 5, and the pair of elastic steel plates 4 gradually open. The elastic steel plates 4 drive the locking block 8 to engage with the corresponding locking groove 13, realizing the installation of the handle 2 and the housing 1. Twisting the anti-slip ring 11 in the opposite direction facilitates the disassembly of the handle 2. The setting of multiple grooves 12 facilitates the adjustment of the grip angle, and the cooperation between the squeezing block 9 and the pressure sensor 10 facilitates the detection of the installation accuracy of the handle 2.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
