Description

Technical Field

[0001] This utility model relates to the field of flipping device technology, and in particular to a manual flipping mechanism. Background Technology

[0002] In industrial inspection, assembly, and handling applications, it is often necessary to perform angle-flipping operations on supported equipment or workpieces, especially when flipping at multiple angles in the vertical direction, making equipment attitude control particularly critical. Traditional flipping mechanisms mostly use electric or hydraulic drives, which are not only complex in structure, high in cost, and inconvenient to maintain, but also unsuitable for some small or portable applications.

[0003] Meanwhile, existing manual tilting mechanisms generally suffer from poor adjustment precision, difficulty in locking, and unintuitive angle display, failing to balance ease of operation with precise tilting control, thus limiting their widespread use in light to medium load applications. Therefore, there is an urgent need for a manual tilting mechanism that is simple in structure, reliable in tilting, adjustable in angle, lockable in posture, and easy to move, to improve the equipment's versatility and operational efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a manual flipping mechanism that solves the problems of poor adjustment accuracy, unstable posture control, and limited movement of existing manual flipping structures.

[0005] This utility model is achieved using the following technical solution: a manual flipping mechanism, characterized in that it includes a bracket with a set of universal wheels at its bottom; a flipping assembly including a bearing seat one and a bearing seat two mounted on both sides of the bracket, and a load bracket rotatably connected to the bearing seat one and bearing seat two via rotating shafts on both sides; and a drive assembly including a handwheel and a pull rod mounted on the rotating shaft that mates with the bearing seat two, wherein the handwheel and the pull rod are both connected to the rotating shaft via a key, and the handwheel is used to drive the load bracket to flip around the rotating shaft. Through the above structure, the flipping mechanism possesses the characteristics of compact structure, flexible rotation, and adaptability to different loads, making it suitable for medium and light load flipping applications.

[0006] Furthermore, the handwheel and the pull rod are axially positioned by a pressure plate, which is fixed to the end of the rotating shaft by screws. This design effectively prevents axial displacement of the handwheel and pull rod during operation, ensuring structural stability and accurate force transmission during the flipping operation.

[0007] Furthermore, the end of the pull rod furthest from the pivot is hinged to a double-ended screw assembly, and the other end of the double-ended screw assembly is hinged to a guide rail clamp via an adapter. The guide rail clamp can slide along a guide rail mounted on the bracket. With this structural configuration, the guide rail clamp can slide dynamically during load flipping while also possessing locking capability, thereby ensuring posture maintenance at any angle.

[0008] Furthermore, the double-ended screw assembly includes a lead screw with left-hand and right-hand trapezoidal threads. The lead screw has end bearings at both ends and a handle in the middle for manual adjustment of the lead screw length. This structure allows for precise fine-tuning of the flip angle by simultaneously driving the two ends to move in opposite directions while rotating the middle handle, meeting the application requirements for high attitude accuracy.

[0009] Furthermore, the flipping mechanism is equipped with an angle gauge and a pointer for indicating the flipping angle. The angle gauge is fixed to one side of the support column, and the pointer is fixed to the end face of the pull rod, used to indicate the flipping angle of the load bracket. This mechanical angle indication structure allows for real-time and intuitive observation of the flipping angle, eliminating the need for additional electronic equipment, and is simple to operate and highly reliable.

[0010] Furthermore, the bearing housing one and bearing housing two are respectively installed on the outside of the two columns of the bracket to form the rotation fulcrum of the load bracket.

[0011] Furthermore, the omnidirectional wheel assembly comprises four sets, which are respectively installed at the four corners of the bottom of the bracket.

[0012] The advantages of the manual flipping mechanism described in this utility model include:

[0013] The mechanical handwheel drive allows users to easily flip the load; the double-headed screw assembly adjustment mechanism enables fine-tuning of the flip angle, and the guide rail clamps fix the flip position; the angle ruler and pointer structure provide mechanical indication of angle changes without the need for electronic sensors; and the bottom of the flip mechanism is equipped with casters for flexible movement in various situations.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example 1

[0019] like Figure 1 As shown, this embodiment provides a manual flipping mechanism, including a bracket 3, a bearing seat 1, a bearing seat 2 14, a load bracket 2, a set of universal wheels 4, an angle ruler 5, a pointer 6, a handwheel 7, a pressure plate 8, a pull rod 9, a double-headed screw assembly 10, a guide rail 11, an adapter 12, and a guide rail clamp 13.

[0020] Specifically, the bottom of the bracket 3 is equipped with four sets of omnidirectional wheels 4, providing omnidirectional movement. The two side columns of the bracket 3 are respectively equipped with bearing housing 1 and bearing housing 2 14 to support the tilting shaft. The load bracket 2 has shafts on its left and right sides, which cooperate with bearing housing 1 and bearing housing 2 14 to achieve load tilting support.

[0021] The pull rod 9 is mounted on the shaft that mates with the bearing housing 14. Axial positioning is achieved through a step on the shaft, and torque is transmitted to the shaft via a key. The handwheel 7 is also mounted on the shaft and is connected via a key to input the tilting drive force. The handwheel 7 and the pull rod 9 are axially positioned by a pressure plate 8, which is fixed to the end face of the shaft with screws.

[0022] The other end of the pull rod 9 is hinged to the double-ended screw assembly 10. This assembly consists of a lead screw with forward and reverse trapezoidal threads and rod end bearings at both ends, and the other end is hinged to the guide rail clamp 13 via an adapter 12. The guide rail clamp 13 is mounted on the guide rail 11 and can slide vertically along the guide rail.

[0023] The double-ended screw assembly has a handle in the middle, which can be manually rotated to change the screw length and fine-tune the flipping angle. When the load needs to be flipped, the operator can rotate the handwheel 7, which transmits power to the load bracket 2 via a key, causing it to flip vertically around the bearing seat axis. The load bracket 2 drives the pull rod 9 to rotate via a key, and the pull rod 9 then drives the double-ended screw assembly 10 to move up and down, thereby driving the guide rail clamp 13 to slide along the guide rail 11. Before flipping, the brake mechanism of the guide rail clamp 13 must be released, and after flipping to the correct position, the guide rail clamp is locked to maintain the position.

[0024] In addition, to achieve real-time display of the flip angle, an angle ruler 5 is fixedly installed on one side of the support column, and it is equipped with scale lines to indicate the flip angle. A pointer 6 is fixed to the end face of the pull rod 9, and indicates the angle change as the pull rod rotates.

[0025] This manual tilting mechanism has a simple structure, is easy to manufacture and maintain, and is suitable for scenarios where equipment or work platforms can be tilted in a controlled manner under medium to light loads. It is especially suitable for occasions where it needs to be used in conjunction with an omnidirectional mobile chassis. Example 2

[0026] This embodiment is a further optimization based on Embodiment 1, specifically:

[0027] The double-ended screw assembly 10 is configured as an adjustable-length mechanism for fine-tuning the flip angle. One end is hinged to the end of the pull rod 9 via a spherical bearing, and the other end is hinged to the guide rail clamp 13 via an adapter 12. A handle is provided in the middle of the double-ended screw assembly 10. By rotating the handle, the operator can drive the forward and reverse trapezoidal thread mechanism to change the length, thereby causing the guide rail clamp 13 to move vertically on the guide rail 11 for fine-tuning, thus achieving fine-tuning of the load bracket 2's posture.

[0028] Specifically, the double-ended screw assembly 10 has rod end joint bearings at both ends to ensure the rotational freedom of the hinged parts during adjustment, preventing abnormal force or interference at the connection due to changes in the rod angle. The middle section has a double-threaded structure, consisting of left-handed and right-handed trapezoidal threads. A handle is installed in the middle section of the screw; rotating the handle moves both ends simultaneously in opposite directions, thus achieving rapid and precise adjustment of the overall length.

[0029] This structural design allows for precise angle setting by fine-tuning the double-headed screw assembly after the flipping mechanism has been adjusted to a large angle. This meets the application requirements for high load flipping accuracy and improves the controllability and reliability of the entire device. Example 3

[0030] This embodiment is a further optimization based on Embodiment 1, specifically:

[0031] The flipping mechanism is equipped with a structure for real-time indication of the flipping angle, including an angle ruler 5 fixed to one side of the support column 3 and a pointer 6 fixed to the end face of the pull rod 9. The two work together to accurately display the flipping angle of the load bracket 2 during the flipping process.

[0032] Specifically, the angle gauge 5 is installed on the outer surface of one of the columns of the bracket 3, and has scale lines on it to indicate the range of rotation angles. The pointer 6 is fixedly installed at the end of the pull rod 9 and rotates synchronously with the rotation of the pull rod 9, so that the pointer moves within the scale range of the angle gauge 5 to indicate the angle change. Since the pull rod 9 is coaxially installed with the load bracket 2 and the rotational motion is transmitted by a key connection, the rotation angle of the pull rod 9 is equivalent to the rotation angle of the load bracket, thus giving the angle display good synchronization and accuracy.

[0033] This angle indicator structure is characterized by its simple structure and intuitive readings. It can provide mechanical angle indication without the use of electronic sensors, making it suitable for cost-sensitive or environmentally restrictive work environments, thus improving the overall ease of use and operational safety of the machine.

[0034] The above embodiments describe the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Modifications and variations made by those skilled in the art without departing from the spirit and scope of this utility model should be protected within the scope of the appended claims.
