Description

Technical Field

[0001] The utility model relates to the field of rotating mechanisms, and particularly to a rotating mechanism for high-strength tools. Background Art

[0002] Rotating mechanisms can also be shaft mechanisms or hinge mechanisms and have a wide range of applications in many fields. These include but are not limited to: tools, medical products, military products, special lamps, and other fields. In the field of mechanical manufacturing, movable parts in various mechanical equipment often achieve flexible rotation through rotating mechanisms, and relative rotation between two objects can be realized. The rotating mechanism enables relevant components to rotate relative to each other according to design requirements to meet various functional requirements.

[0003] Existing rotating mechanisms usually consist of a rotating part, a fixed part, and a rotating shaft connecting the two. The rotating part rotates around the rotating shaft, and the fixed part plays a role in supporting and fixing the rotating shaft. During use, an external force acts on the rotating part to make it rotate around the rotating shaft, thereby realizing functions such as the opening and closing or angle adjustment of relevant components. By reasonably designing the position of the rotating shaft, the shape and size of the rotating part, etc., the smoothness and accuracy of rotation are ensured.

[0004] However, although existing rotating mechanisms have been widely used in many fields, there are still some defects and deficiencies. First, in terms of strength, the rotating shafts of existing rotating mechanisms are prone to deformation or even damage when subjected to large external forces or frequent use, affecting their service life and reliability. Second, as the rotating mechanism is used over time, the connection structure strength of its existing rotating shaft is insufficient, resulting in easy failure when the rotating mechanism drives the fixed part to rotate and possible safety hazards in the fixed part of the connecting piece on the rotating shaft, thereby leading to poor use stability and reliability. In addition, the limiting effect of existing rotating mechanisms is poor, affecting the rotational use of the rotating mechanism. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above defects and provide a rotating mechanism for high-strength tools to solve the technical problems in the above background art that the connection structure strength of the rotating mechanism is insufficient, resulting in poor use stability and reliability, and the limiting effect of the rotating mechanism is not good, thus affecting the use of the rotating mechanism.

[0006] The purpose of the utility model is achieved in the following way:

[0007] A rotating mechanism for a high-strength tool, comprising a fixed seat. On opposite sides of the fixed seat, a first connection end and a second connection end are respectively formed by integral molding. A detachable first movable frame is connected to the first connection end through a first limiting component. The end of the first movable frame is sleeved with the first connection end and can perform a rotating action relative to the first connection end. A detachable second movable frame is connected to the second connection end through a second limiting component. The end of the second movable frame is sleeved with the second connection end and can perform a rotating action relative to the second connection end.

A detachable third movable frame is connected to the third connection end through a third limiting component. The third movable frame is sleeved with the third connection end and can perform a rotating action relative to the third connection end.

[0008] Further in the above description, the end parts of the first connection end and the second connection end respectively extend outward from the fixed seat. The first connection end and the second connection end are symmetrically distributed on both sides of the fixed seat.

[0027] The present utility model will be further described in detail below in conjunction with the drawings and the specific implementation mode.

[0028] In this embodiment, referring to Figures 1-5 FIG., a rotation mechanism of a high - strength tool in its specific implementation includes a fixed seat 100. On opposite sides of the fixed seat 100, a first connection end 101 and a second connection end 102 are integrally formed respectively.

[0030] Specifically, in this embodiment, the first movable frame 400 and the second movable frame 500 are used to connect external fixed components through the first connection part and the second connection part, so as to drive the fixed components to rotate.

[0031] In this embodiment, referring to Figure 3 and Figure 4, a third connection end 103 is integrally formed on the fixed seat 100. The third connection end 103 is disposed between the first connection end 101 and the second connection end 102. A detachable third movable frame 600 is connected to the third connection end 103 through a third limiting component 700. The third movable frame 600 is sleeved on the third connection end 103 and can rotate relative to the third connection end 103.

[0032] The end portions of the first connection end 101 and the second connection end 102 extend outward from the fixed seat 100. The first connection end 101 and the second connection end 102 are symmetrically distributed on both sides of the fixed seat 100. The end portions of the first connection end 101 and the second connection end 102 extending away from the fixed seat 100 are respectively formed with a first locking portion 104 and a second locking portion 105.

[0033] Specifically, in this embodiment, both the first connection end 101 and the second connection end 102 are in the shape of a pivot. The first connection end 101 and the second connection end 102 are integrally formed on both sides of the fixed seat 100, further improving the stability and reliability of the connection and use of the first movable frame 400 and the second movable frame 500, and enhancing the structural strength and accuracy of the first connection end 101 and the second connection end 102.

[0034] In this embodiment, referring to Figure 3 and Figure 5 , both the first limiting component 200 and the second limiting component 300 are composed of a first hook gasket 201, four flat gaskets 202 and a first elastic sheet group 203. The first hook gasket 201 of the first limiting component 200 and the first hook gasket 201 of the second limiting component 300 are respectively connected to the first movable frame 400 and the second movable frame 500 through a hook portion 204.

[0035] The first elastic sheet group 203 includes four dish-shaped elastic sheets with central openings stacked together. The dish-shaped elastic sheets are stacked in pairs, and the protruding parts of the two groups of elastic sheets are abutted against each other. The first elastic sheet group 203 is disposed between two flat gaskets 202 and can apply an adjustable axial elastic force to the first movable frame 400 or the second movable frame 500.

[0036] Specifically, referring to Figure 3 and Figure 5, the installation steps of the first limiting component 200 and the second limiting component 300 with the first movable frame 400 and the second movable frame 500 are to coaxially install the flat gasket 202, the first movable frame 400 or the second movable frame 500, the flat gasket 202, the first hook gasket 201, the flat gasket 202, the first elastic piece group 203, the flat gasket 202, and the first locking piece 800 or the second locking piece 900 on the first connection end 101 or the second connection end 102 in sequence.

[0037] Specifically, setting the first limiting component 200 and the second limiting component 300 can enhance the limiting effect of the rotation of the first movable frame 400 and the second movable frame 500, that is, improve the stability and reliability of the rotation of the first movable frame 400 and the second movable frame 500.

[0038] Refer to Figure 3 and Figure 4 , the third movable frame 600 includes a movable frame one 601, a movable frame two 602, and a movable frame three 603. The movable frame one 601, the movable frame two 602, and the movable frame three 603 are sequentially sleeved on the third connection end 103. The movable frame one 601, the movable frame two 602, and the movable frame three 603 are sequentially connected by bolts to form the third movable frame 600. A stop portion 107 is formed at the end of the fixed seat 100 close to the third connection end 103. The stop portion 107 extends towards the third connection end 103. A limiting portion 604 is formed inside the through-hole one of the movable frame one 601. When the third movable frame 600 rotates relative to the third connection end 103, the limiting portion 604 of the movable frame one 601 rotates to the stop portion 107 to form a clamping limit.

[0039] Through the setting of the third movable frame 600, it can rotate along the third connection end 103. The cooperation between the limiting portion 604 provided on the movable frame one 601 and the stop portion 107 limits the rotation angle of the third movable frame 600, improves the limiting strength, and thus can meet the connection and rotation requirements of products and tools.

[0040] Refer to Figure 3 and Figure 4 , the third limiting component 700 is composed of a limiting gasket 701, a second hook gasket 706, two oil-accumulating gaskets 702, and a second elastic piece group 703 that are sleeved on the third connection end 103.

A stop protrusion 704 is formed on the limiting gasket 701. A limiting protrusion 606 is formed on the movable frame three 603. When the third movable frame 600 rotates relative to the third connection end 103, the limiting protrusion 606 of the movable frame three 603 rotates to the stop protrusion 704 to form a clamping limit.

[0041] The rotation angle of the third movable frame 600 is limited by the cooperation between the limit protrusion 606 on the movable frame three 603 and the stop protrusion 704, which can further improve the limit strength, thus meeting the connection and rotation requirements of products and tools.

[0042] The second elastic sheet group 703 includes six disc-shaped elastic sheets with central openings stacked together. Every three disc-shaped elastic sheets are stacked in sequence, and the protruding parts of the two groups of elastic sheets are arranged adjacent to each other. The second elastic sheet group 703 is arranged between two oil-gathering gaskets 702 and can apply adjustable axial elastic force to the third movable frame 600.

[0043] Specifically, the installation steps of the third limit assembly 700 and the third movable frame 600 are as follows: the limit gasket 701, the first movable frame 601, the second movable frame 602, the third movable frame 603, the second hook gasket 706, the oil-gathering gasket 702, the second elastic sheet group 703, the flat gasket 202 and the third locking part 1000 are coaxially installed on the third connection end 103 in sequence.

[0044] A limit hanging ear 705 is formed by bending on the second hook gasket 706. Clamping grooves 605 paired with the limit hanging ear 705 are opened on both the third movable frame 603 and the second movable frame 602, and the limit hanging ear 705 passes through the clamping grooves 605 of the third movable frame 603 and the second movable frame 602 for clamping connection.

[0046] The first connection end 101, the second connection end 102 and the third connection end 103 are integrally formed on the fixing seat 100, which further improves the strength of the connection structure and the stability in use, enhances the overall structural strength, makes the structures of the first connection end 101, the second connection end 102 and the third connection end 103 more reliable, and thus increases the service life. At the same time, the integrally formed structure also makes the fixing seat 100 more compact, saves space, and is conducive to the miniaturization and lightweight design of the product.

[0047] In this embodiment, referring to Figure 4 , the first connection end 101, the second connection end 102 and the third connection end 103 are arranged in a pivot shape, the first locking part 104, the second locking part 105 and the third locking part 106 are provided with threads, and the first locking part 800, the second locking part 900 and the third locking part 1000 are all composed of nuts.

At the same time, the third movable frame 600 is installed on the third connection end 103 of the fixed seat 100 through the third limiting component 700, so that the first movable frame 400, the second movable frame 500 and the third movable frame 600 can rotate in multiple directions along the fixed seat 100, improving the flexibility and practicability of the rotating mechanism. The fixed seat 100 adopts an integral molding process, which can enhance the overall structural strength of the rotating mechanism, reduce the risk of loosening of the first connection end 101, the second connection end 102 and the third connection end 103 caused by assembly, improve the stability and durability of the connection mechanism, and can reduce the processing procedures and assembly difficulty in the manufacturing process, reducing the production cost.
