Description

Technical Field

[0001] The utility model relates to the field of buckle devices, and more specifically, to a rotating head. Background Art

[0002] In daily life and industrial applications, various occasions where straps need to be fixed and adjusted are very common, such as the straps of suitcases, the adjustment of shoulder straps of backpacks, the bundling and fixing of outdoor equipment, etc. In these scenarios, strap buckles are one of the indispensable components. Traditional strap buckles are usually simply designed and mainly fix the strap through mechanical buckles or friction. However, this traditional design has the following technical problems and deficiencies:

[0003] Strap loosening or slipping: Due to the lack of an effective locking mechanism, traditional strap buckles are prone to loosening or slipping when subjected to external forces or continuous vibrations, especially during outdoor sports, long - distance travel or transportation, which may cause the strap to come loose and result in the loss or damage of items. This situation is particularly prominent in application scenarios that require frequent adjustment or long - term fixation.

[0004] Uncontrolled rotation: In many application scenarios, it is necessary to control the fixing angle or direction of the strap. However, traditional strap buckles usually do not have an effective function to limit the rotation angle or direction of the strap, resulting in problems such as deflection and misalignment of the strap during use, and unable to ensure the stability and safety of the fixed items.

[0005] Poor durability: Some traditional buckles are made of low - quality materials and are prone to wear during multiple uses, resulting in the failure of the buckle or the inability to firmly fix the strap anymore. Such a design is difficult to meet the requirements in high - load application scenarios, such as industrial bundling and outdoor equipment fixation.

[0006] Lack of versatility and applicability: Most of the existing strap buckles only have basic fixing functions and lack the flexibility to adapt to different environments and application scenarios. For example, in some occasions, users hope to make small - range adjustments without changing the position of the strap, but traditional buckles often cannot provide such operational convenience.

[0007] Based on the above problems, there is an urgent need in the market for a new type of rotating head that can provide a more secure fixing effect while maintaining a simple structure, and can effectively limit the rotation range of the strap to meet the requirements of different application scenarios. Summary of the Utility Model

[0008] To solve the above problems, the utility model provides a rotating head. Through a clever structural design, it realizes the fixation of the strap and the limitation of the rotation range, effectively solves problems such as loosening, slipping and uncontrolled rotation in the prior art, and enhances the reliability and safety of the strap fixation.

[0009] To achieve the above object, the present utility model provides the following technical solutions, mainly including:

[0010] Strap buckle: The whole is an integrally formed structure, provided with a through hole for passing through the strap, capable of firmly fixing the strap to prevent it from sliding or loosening.

[0011] Rotating column: Connected to the strap buckle, capable of rotating relative to the strap buckle. A fixed head is provided at the free end of the rotating column, and the fixed head is used to cooperate with external components to achieve the fixation of the strap.

[0012] Fixed head: An integrally formed part of the rotating column, having a non-circular cross-sectional structure, which can form a tight fit with external accessories, increasing the connection stability and anti-slip performance.

[0013] Limit ring: Arranged at the middle position of the rotating column, used to limit the rotation range of the rotating column relative to the strap buckle. The limit ring contacts the inner wall of the strap buckle to prevent the axial displacement of the rotating column.

[0014] The limit ring is made of an elastic material, capable of adapting to different sizes of rotating columns and strap buckles, and providing sufficient friction to limit rotation.

[0015] According to the above technical solutions, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] (1) It provides a firm strap fixation effect, preventing the strap from loosening or slipping during use, and is suitable for high-load scenarios.

[0017] (2) It limits the rotation range of the strap, avoids deflection and misalignment, and improves the safety and stability of use.

[0018] (3) The structure is simple, the operation is convenient, it is easy to install and adjust, and it meets different application requirements.

[0019] (4) Adopting an elastic limit ring design, it has strong adaptability and can adapt to different sizes and use environments.

[0020] (5) It has high durability, the overall structure is firm, suitable for long-term use, and improves the product life. Description of the Drawings
