Description

Technology Field

[0001] The present invention relates to a rotary handle device for ground equipment. Background Technology

[0003] When using existing pentagonal operating handles, various problems arise due to the movement of the handle. For example, when an operator operates with one hand, significant force is required to prevent the pentagonal bolt connection from coming loose and to secure the handle. Additionally, since the operating handle and the head are not fixed, the handle moves during operation, causing inconvenience.

[0004] When the control handle is directed downward, the center of gravity shifts downward, causing the handle to detach. Interference occurs due to insufficient clearance between the hand holding the handle and the ground equipment. Additionally, there is a lack of space between the ground equipment and the operator's hand, and the hand rubs against the ground when operating the lower bolt. The problem to be solved

[0006] An embodiment of the present invention is intended to provide a rotary handle device for a ground device that can be easily operated by a worker by forming a handle portion, which is connected to the ground device to implement the operation function of a locking device, in a rotatable form. means of solving the problem

[0009] The connection can be formed as an S-shaped curved metal structure.

[0010] The head portion provided in the locking device of the ground equipment can be formed in the shape of a pentagonal bolt. Effects of the invention

[0012] It can provide a safe working environment for the operator to operate the locking device of the ground equipment, and by securing the angle of the bending part of the rotary operating handle, it has the effect of preventing the operator's hand from scraping against the surface of the ground equipment and the ground.

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein.

[0018] FIG. 1 is a schematic diagram illustrating a rotary handle device for a ground device according to an embodiment of the present invention, and FIG. 2 is a schematic diagram illustrating a prototype state of a rotary handle device for a ground device according to an embodiment of the present invention. FIG. 3 is a schematic diagram illustrating an example of use of a rotary handle device for a ground device according to an embodiment of the present invention.

[0019] Referring to FIGS. 1 to 3, a rotary handle device (100) for a ground device according to an embodiment of the present invention includes a socket part (110), a connecting part (120), a handle part (130), and a pulley part (140). The handle part (130), which is connected to the ground device (10) to implement the operation function of the locking device (12), is formed in a rotatable form so that a worker can easily operate it.

[0020] The socket portion (110) may be formed in the shape of a connecting part of the same size as the head portion of the locking device (12) of the ground device (10). Here, the head portion provided in the locking device (12) of the ground device (10) may be formed in the shape of a pentagonal bolt. The socket portion (110) may be formed in the shape of a connecting part of the same size as the head portion of the pentagonal bolt provided in the locking device (12) of the ground device (10).

[0021] One side of the connecting part (120) is connected to the socket part (110), and it can be formed with a pre-set curved shape to maintain a gap between the outer casing of the ground device (10) and the worker's hand. The connecting part (120) can be formed as an S-shaped curved metal structure. By forming the connecting part (120) with a pre-set curved shape as an S-shaped curved metal structure, the gap between the outer casing of the ground device (10) and the worker's hand can be easily maintained.

[0022] The handle portion (130) is connected to the other side of the connecting portion (120) and can be formed in a structure that can be easily grasped by the worker's hand. The handle portion (130) has a rotatable structure and is formed in a shape that can be easily grasped by the worker's hand, thereby allowing the worker to easily grip the handle portion (130).

[0023] The pulley portion (140) is connected to the connecting portion (120) and the handle portion (130), respectively, and can assist in enabling rotational movement of the handle portion (130). By connecting the pulley portion (140) to the connecting portion (120) and the handle portion (130) and assisting in enabling rotational movement of the handle portion (130), the operator can operate the handle portion (130) more easily.

[0024] A handle portion (130) that is connected to the ground device (10) and implements the operation function of the locking device (12) is formed in a rotatable shape so that the operator can easily operate it. A connecting portion (120) can be formed with a preset angle of bending to maintain a distance between the outer casing of the ground device (10) and the operator's hand. Through the connecting portion (120), the pentagonal bolt and the handle portion (130), which is the handle, can be maintained at an appropriate distance to prevent interference with the ground when working on the lower bolt on the outer casing of the ground device (10). The socket portion (110) is in close contact with the head portion of the pentagonal bolt and can rotate in a fixed position, and through the rotation assist function of the pulley portion (140) connected to the handle portion (130), the operator can operate the locking device (12) of the ground device (10) with less force.

[0025] As described above, the rotary handle device (100) for ground equipment according to an embodiment of the present invention can provide a safe working environment for a worker to operate the locking device (12) of the ground equipment (10). In addition, it can prevent hand pinching accidents caused by the movement structure based on the center of gravity of existing operating handles. For example, by securing the angle of the bending part of the handle part (130) capable of rotary operation, the phenomenon of the worker's hand scraping against the outer surface of the ground equipment (10) and the ground can be prevented. Furthermore, the worker's force is evenly distributed to the end of the pentagonal bolt, thereby preventing uneven wear. Therefore, the worker can operate with one hand instead of two, making it possible to prevent musculoskeletal disorders.

[0026] Although preferred embodiments of the present invention have been described above, the present invention is not limited thereto and can be implemented with various modifications within the scope of the claims, the detailed description of the invention, and the attached drawings, and it is obvious that such modifications also fall within the scope of the present invention.
