Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, and in particular to a polishing hand support structure. Background Technology

[0002] During the polishing process, workers hold angle grinders. Due to the high speed of the angle grinder, it is sometimes difficult to hold it steadily, especially for larger and heavier angle grinders. Hand tremors may occur after long periods of operation, affecting polishing efficiency. Moreover, a slight mistake could lead to a safety accident and injure the worker. Therefore, an auxiliary support structure is needed to reduce the weight on the hands and improve safety during polishing.

[0003] Chinese Patent Grant Announcement No.: CN 221474664 U, Grant Announcement Date: August 6, 2024. This application proposes a support for an electric angle grinder, including a platform. A horizontal moving structure for moving a column in the horizontal direction is installed on one side of the platform. A vertical moving structure for moving a support arm in the vertical direction is installed on the column. The support arm is connected to a lower seat via an angle adjustment structure. An upper seat is connected to one side of the lower seat via a hinge. The ends of the lower and upper seats without hinges have ear seats protruding outward. The ear seats of the lower and upper seats are fixedly connected by bolts and nuts. The ear seats have through holes that allow bolts to pass through. A contoured support block is fixed inside the lower seat. A contoured pressure block is provided above the contoured support block. A pressing structure for pressing the contoured pressure block is installed on the upper seat. The outer wall of the contoured pressure block slides against the inner wall of the upper seat. The inner wall of the upper seat is directly opposite the inner wall of the lower seat. The shortcomings of this technical solution are: the positioning of the grinding position by the servo motor is prone to misalignment and has low accuracy; the electric method is prone to damage; and the poor operational flexibility during grinding reduces its practicality.

[0004] In summary, existing support structures suffer from low operational precision, poor operational flexibility, and reduced practicality. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing support structures, such as low working accuracy and poor operational flexibility, which reduce practicality, and provides a grinding hand placement support structure that can improve working accuracy, operational flexibility and practicality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A polishing hand support structure, including The base is movably connected to a support rod. A movable support frame, which is movably connected to a support rod; A fixed frame is rotatably connected to a movable support. The fixed frame has a fixing hole, and the grinding machine body is detachably connected to the fixing hole. Anti-slip bracket, the anti-slip bracket is connected to the grinding machine body; The locking structure is movably connected to the base and movably connected to the support rod.

[0007] The support rod connects the grinding machine body to the movable bracket via a fixed frame. The movable bracket can move on the support rod, allowing for height adjustment of the grinding machine body. Simultaneously, the fixed bracket can rotate on the movable bracket, ensuring stable overall rotation of the grinding machine body. The anti-slip bracket facilitates manual operation of the grinding machine body's rotation. Combined with the movement of the support rod on the base, this allows for forward, backward, and vertical movement of the grinding machine body, with stable rotation during movement. This enables flexible adjustment based on workpiece position. During manual operation, the bracket structure allows for indirect operation by placing the hand on it; the grinding machine body is supported, and the hand can rotate it by gripping the anti-slip bracket to complete the grinding and cutting action, eliminating the need for the hand to constantly hold the grinding machine and bear its entire weight, thus reducing the gripping force required and minimizing muscle strain. The locking structure allows for locking the support rod in position, facilitating batch grinding. This achieves the effects of improving the flexibility and positioning accuracy of the bracket structure, facilitating hand placement and easy operation, saving manpower, protecting hands, and enhancing safety and practicality.

[0008] Preferably, the movable support includes a movable rod, a support rod connected to a fixed ring, and the movable rod and fixed ring threadedly connected. The fixed frame includes a movable block with a rotating hole. One end of the movable rod is connected to a limiting circular plate, which is connected to the rotating hole. The other end of the movable rod is connected to an anti-slip block. The movable rod in the movable support, through its threaded connection to the fixed ring on the support rod, allows for stable and precise vertical adjustment on the support rod. The movable rod, connected to the movable block via the limiting circular plate, causes the movable block to move accordingly, thereby allowing the grinding machine body on the fixed frame to move and adjust its height. This achieves the effect of improving the stability and precision of the support structure's height adjustment.

[0009] Preferably, the fixing frame includes an upper clamping block and a lower clamping block. One end of the upper and lower clamping blocks is rotatably connected to the moving block, and the other end of the upper clamping block is bolted to the other end of the lower clamping block. The fixing hole is the space between the upper and lower clamping blocks. Both the upper and lower clamping blocks have buffer anti-slip pads attached to their inner walls, which are fitted onto the grinding machine body. The upper and lower clamping blocks are rotatably connected to the moving block to support the rotation of the grinding machine body. The grinding machine body is fixed to the support structure by the encirclement and bolting of the upper and lower clamping blocks. The buffer anti-slip pads press against the grinding machine body when clamped, protecting the grinding machine body and preventing it from slipping. This achieves the effect of ensuring the assembly stability of the grinding machine body and facilitating loading, unloading, and maintenance.

[0010] Preferably, both the upper and lower clamping blocks are equipped with rotating blocks, and the movable block has a second rotating hole. One end of the rotating block is rotatably connected to the second rotating hole, and the other end of the rotating block is inserted into a rotating rod. Both the upper and lower clamping blocks have insertion holes, and the rotating rod is inserted into the insertion holes. The rotating block rotates on the movable block by connecting to the second rotating hole, and the other end is inserted into the insertion hole via the rotating rod. This allows the upper and lower clamping blocks to rotate stably under the support of the rotating rod, resulting in smooth and stable opening and closing actions. This improves the stability of the connection between the structures of the support and the smoothness of operation.

[0011] Preferably, the anti-slip bracket includes a housing and an anti-slip sleeve. The anti-slip sleeve is connected to the inner wall of the housing and is fitted onto the tail end of the grinding machine body. An operating handle is connected to the housing, and a limiting support rod is connected to the operating handle. The housing of the anti-slip bracket is inserted into the tail end of the grinding machine body via the anti-slip sleeve, facilitating control of the grinding machine body via the operating handle. The limiting support rod supports hand movements and prevents slippage. This further enhances labor-saving and operational convenience.

[0012] Preferably, the base is equipped with a guide groove, and a movable base plate is connected to the base. The movable base plate is slidably connected to the guide groove, and the support rod is connected to the movable base plate. The base allows the movable base plate to move in a specific direction via the guide groove, thereby enabling the support rod to move stably and directionally on the base. This enhances the operational stability of the support structure.

[0013] Preferably, the locking structure includes a plug rod and a movable base. The support rod has a locking groove, the base has a side sliding groove, the movable base is slidably connected to the side sliding groove, one end of the plug rod is rotatably connected to the movable base, and the plug rod is movably inserted into the locking groove. The plug rod in the locking structure can enter or leave the locking groove by rotating on the movable base. This allows the support rod to be locked when the movable base plate needs to be fixed and unlocked when flexible movement is required. The movable base can slide along the side sliding groove, allowing the plug rod to follow the position of the support rod for locking. This improves the operational flexibility and stability of the support structure.

[0014] Preferably, the locking structure includes a locking rod, a base connected to a stabilizing block, a locking rod threadedly connected to the stabilizing block, and a rotatable connection between the locking rod and the movable seat. The locking rod in the locking structure can move back and forth on the base via the stabilizing block, thereby driving the movable seat to move back and forth to match the movement of the support rod, and simultaneously locking it when fixed. This further improves the flexibility and stability of the support structure's movement.

[0015] The beneficial effects of this utility model are: improving the flexibility and positioning accuracy of the support structure; facilitating hand placement and easy operation to save manpower; protecting hands and improving safety and practicality; improving the stability of the support structure height adjustment; ensuring the assembly stability of the grinding machine body and facilitating loading, unloading and maintenance; and improving the connection stability and operation smoothness between the support structures.
