Description

Technical Field

[0001] This utility model relates to shell connection structure technology in the field of mechanical engineering, specifically to a design of a rotating shaft device for shell equipment that can be opened in any direction, suitable for shell equipment such as cabinets and racks that have high requirements for installation direction and opening flexibility. Background Technology

[0002] Existing enclosure devices typically have their top covers fixedly connected to the housing via structures such as copper shafts, steel shafts, wire rings, or pins, allowing them to open only in a predetermined, single direction. This design has the following limitations:

[0003] 1. Fixed opening direction: Due to limitations in the installation environment (such as narrow corridors or specific cabinet layouts), if the installation direction of the shell conflicts with the opening direction, it will result in insufficient opening space and inability to operate;

[0004] 2. Limited installation direction: Scenarios such as network cabling require the enclosure to be installed in a fixed direction, which cannot adapt to diverse site requirements;

[0005] 3. Limited structural function: Traditional hinge structures lack flexibility and are difficult to meet the dynamic adjustment requirements for the opening direction in complex scenarios.

[0006] Therefore, there is an urgent need for a new hinge structure that can open in any direction to solve the problem that the existing shell hinge structure can only open in one direction and the installation direction is limited, resulting in its insufficient applicability in scenarios with limited space or requiring flexible installation. Utility Model Content

[0007] The purpose of this utility model is to address the aforementioned problems in the existing technology by providing a pivot structure that can be opened in any direction. By setting a screw assembly consisting of a pivot pin, screws, springs, etc. around the perimeter of the housing, and utilizing the elastic fixation of the springs and the symmetrical structure of the U-shaped groove, the screw assembly on any side can be switched to a pivot, while the screw assemblies on the other three sides can be released from the locked state, thereby realizing the opening and flexible installation of the housing cover in any direction.

[0008] In order to achieve the above-mentioned application objectives, the present invention adopts the following technical solution: a rotating shaft structure that can be opened in any direction includes an outer shell cover, an outer shell bottom, and a screw assembly disposed around the outer shell, and the edge of the outer shell cover is provided with a U-shaped groove;

[0009] The bottom edge of the housing has holes for mounting screw assemblies;

[0010] The screw assembly includes a pivot pin, a screw, a nut, a first washer, a spring, and a second washer;

[0011] One end of the screw is inserted into the U-shaped groove, and the other end is connected to the shaft pin through the thread and passes through the shaft pin to connect with the nut, and is perpendicular to the shaft pin;

[0012] The first washer, the spring, and the second washer are sequentially inserted onto the shaft pin, and the second washer can abut against the screw under the elastic force of the spring.

[0013] The screw assemblies on any three sides can be loosened by pressing the spring to disengage the screws from the U-shaped grooves, while the screw assembly on the remaining side acts as a pivot, allowing the outer cover to be rotated and opened via a pivot pin.

[0014] Furthermore, the U-shaped grooves on either side are arranged symmetrically in pairs.

[0015] Furthermore, the spring presses against the first and second washers with its elastic force, so that the screw remains fixed in the U-shaped groove even when it is loosened.

[0016] Furthermore, a nut is placed at the end of the screw to limit the screw's unscrewing length and prevent it from completely disengaging from the pin.

[0017] Furthermore, a U-shaped groove is provided on the first connecting part on the edge of the outer casing, and a second connecting part is provided on the bottom of the outer casing that corresponds one-to-one with the first connecting part, and the second connecting part is provided with holes for mounting screw assemblies.

[0018] Furthermore, the shell material, consisting of the upper cover and the lower bottom, is either metal or non-metal.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Meets the requirements for opening the lid from multiple directions.

[0021] In existing technologies, the outer cover can only be opened in a fixed direction, limiting its application scenarios. This is especially inconvenient in space-constrained environments such as cabinet installations and narrow corridors. This invention, through a unique screw assembly and outer shell structure design, allows either side to be selected as the pivot, enabling multi-directional opening of the outer cover. This eliminates space limitations associated with the installation site, significantly improving its flexibility and applicability.

[0022] 2. Not restricted by wiring direction

[0023] Existing technologies restrict the installation direction of the housing to a fixed orientation due to network cabling requirements. This invention, however, is not limited by existing network cabling directions; the housing can be installed and fixed in any direction, providing greater freedom for actual installation. The installation position and direction can be flexibly adjusted according to specific site conditions, facilitating construction and layout.

[0024] 3. Easy to operate

[0025] The opening operation of this utility model is simple and easy. Simply loosen the screws of the corresponding screw assembly to easily open the cover. There is no need for complicated disassembly steps, which saves operation time and improves work efficiency.

[0026] 4. Stable and reliable structure

[0027] The symmetrical U-shaped groove design of the outer casing ensures that the screws on the pivot side will not slip out of the groove and fall out, enhancing the stability of the structure. Meanwhile, the spring design in the screw assembly uses elasticity to hold the first and second washers in place, allowing the screws to be securely fixed in the U-shaped groove of the outer casing, further improving the reliability of the connection and preventing the cover from falling out when opened due to loose screws.

[0028] 5. Excellent waterproof and dustproof performance

[0029] The housing cover and bottom are secured and locked by screws around the perimeter, meeting waterproof and dustproof requirements such as IP68. This effectively protects the equipment inside the housing from external environmental factors, extends the service life of the equipment, and is suitable for various harsh working environments.

[0030] 6. Suitable for a variety of materials

[0031] The shell material of this utility model can be metal or non-metal, and it has a wide range of applications. The appropriate material can be selected according to actual needs to meet the usage requirements in different scenarios.

[0032] 7. Easy to maintain and repair

[0033] Because the cover is easy to open, when maintenance or repair of the equipment inside the casing is required, the cover can be quickly opened, making it convenient for operators to inspect, clean, replace parts, etc., thereby effectively improving equipment maintenance efficiency and reducing maintenance costs.

[0034] 8. Will not damage the original structure

[0035] During the opening process, the screws are simply rotated out of the U-shaped groove on the outer cover, not removed. The screws remain on the pivot pin, which avoids damage to the original fixing structure, ensures the integrity and stability of the shell, and also facilitates repeated opening and closing in the future.

Detailed Implementation

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0043] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0044] like Figure 1-5 As shown, the hinge structure that can open in any direction is fixed and locked to the upper cover 1 and the lower bottom 2 of the outer shell by the screw assembly 3 around the perimeter (the upper cover 1 and the lower bottom 2 of the outer shell constitute the outer shell), which can meet the waterproof and dustproof requirements of the outer shell such as IP68. The shell material can be metal or non-metal.

[0045] The U-shaped groove 11 is provided on the first connecting part on the edge of the upper cover 1 of the outer shell, and the lower bottom 2 of the outer shell is provided with a second connecting part corresponding to the first connecting part, and the second connecting part is provided with holes for the screw assembly 3 to be installed.

[0046] The screw assembly 3 consists of a pin 31, a screw 32, a nut 33, a first washer 34, a spring 35, and a second washer 36. The screw 32 on the screw assembly 3 engages with the U-shaped groove 11 of the outer casing 1 and is threadedly locked to the pin 31, achieving a sealing and fixing effect on the outer casing 1. Specifically, one end of the screw 32 engages with the U-shaped groove 11, and the other end is threaded to the pin 31 and extends through the pin 31 to connect with the nut 33, perpendicular to the pin 31. The first washer 34, spring 35, and second washer 36 are mounted on the pin 31. The second washer 36 abuts against the screw 32 under the elastic force of the spring 35.

[0047] In this embodiment, on any three sides of the outer casing, the screws 32 are loosened, and the spring 35 is pressed towards the spring 35, causing the screws 32 to rotate and disengage from the U-shaped groove 11 of the outer casing cover 1 (not removed; the screws 32 remain on the pin 31). On the remaining side of the outer casing, the screws 32 are loosened, allowing the pin 31 of the screw assembly 3 on that side to act as a pivot, thus allowing the outer casing cover 1 to be rotated open. The screw assembly 3 on the pivot side is held in place by the elasticity of the spring 35 against the first washer 34 and the second washer 36, ensuring that the screws 32 are completely fixed within the U-shaped groove 11 of the outer casing cover 1. The symmetrical design of the U-shaped groove 11 of the outer casing cover 1 prevents the screws 32 on that side from slipping out of the U-shaped groove 11 and falling out. This avoids the possibility of the outer casing cover 1 falling out when rotated open after the screws 32 have loosened.

[0048] The nut 33 on the screw 32 serves as a locking and limiting mechanism to prevent the screw 32 from being completely unscrewed and detached from the threaded hole of the pin 31 when loosened.

[0049] This design enables multi-directional opening of the cover by opening and retaining one side of the screw assembly 3 as a rotation axis, and opening and pushing / pulling out the screw assemblies 3 on the other three sides.

[0050] The parts of this utility model not described in detail are existing technologies, therefore, this utility model does not describe them in detail.

[0051] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0052] Although this document uses a considerable amount of technical terminology, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
