Description

Technical Field

[0001] This application relates to the field of protective covers, and more particularly to a connection structure that prevents falling off. Background Technology

[0002] Currently, in sealing connection structures, protective covers are typically sealed to the container using threaded connections, snap-fit ​​connections, or magnetic attachments. However, once the protective cover is completely detached from the container, it is prone to loss or falling due to the lack of a fixing or connecting structure. Existing technologies use a traction rope to connect the protective cover to the container to prevent loss or falling. However, in some existing solutions, the connecting post is located on the edge of the protective cover. This causes the traction rope fixed to the connecting post to move circumferentially with the cover's rotation during disassembly, as the cover rotates relative to the base. This process easily leads to the traction rope becoming entangled around the connecting post or the protective cover, increasing disassembly resistance and potentially affecting operational efficiency due to excessive tightness.

[0003] Therefore, there is a need for a connection structure that can both enable quick disassembly and prevent the protective cover from being lost. Utility Model Content

[0004] In view of this, it is necessary to provide a connection structure that can achieve quick disassembly and prevent the loss of the protective cover in order to solve the above problems.

[0005] Embodiments of this application provide a connection structure to prevent falling, comprising:

[0006] Base;

[0007] The protective cover is threadedly connected to the base.

[0008] A connecting post extends axially along the center point of the protective cover and is located on the side of the protective cover away from the base;

[0009] The connector has one end on the base and the other end rotatably fitted onto the connecting post.

[0010] In at least one embodiment of this application, the connecting post and the protective cover are integrally connected.

[0011] In at least one embodiment of this application, the connecting column includes a rotating part and a limiting part. One end of the rotating part is disposed on the protective cover, and the other end is connected to the limiting part. The connecting member is sleeved on the rotating part.

[0016] In at least one embodiment of this application, the protective cover has a first threaded portion, which is disposed on the inner wall of the protective cover;

[0017] The connecting part has a second threaded part, which is disposed on the outer wall of the connecting part, and the first threaded part and the second threaded part are connected in a mating manner.

[0018] In at least one embodiment of this application, the base is provided with a first fixing hole and a second fixing hole, the first fixing hole and the second fixing hole are arranged adjacent to each other, wherein the connector passes through the first fixing hole and the second fixing hole in sequence.

[0019] In at least one embodiment of this application, the outer wall of the protective cover also has anti-slip grooves.

[0020] The aforementioned anti-fall-off connection structure comprises a base, a protective cover, a connecting post, and a connector. The protective cover is threaded to the base to ensure a seal.

[0030] Embodiments of this application provide a connection structure to prevent falling, comprising:

[0031] Base;

[0032] The protective cover is threadedly connected to the base.

[0033] A connecting post extends axially along the center point of the protective cover and is located on the side of the protective cover away from the base;

[0034] The connector has one end on the base and the other end rotatably fitted onto the connecting post.

[0035] The aforementioned anti-fall-off connection structure comprises a base, a protective cover, a connecting post, and a connector. The protective cover is threaded to the base to ensure a seal. The connecting post extends axially along the center point of the protective cover and is positioned away from the base. One end of the connector is fixed to the base, while the other end is rotatably fitted onto the connecting post. This design allows the connector to both connect the protective cover and the base, preventing the protective cover from being lost or falling off after completely detaching from the base, and also ensures that the connector can freely rotate around the connecting post when the protective cover and base rotate relative to each other, without creating excessive resistance to the rotation of the protective cover.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] according to Figures 1-5 This application provides a connection structure 100 to prevent falling, including: a base 10; a protective cover 20, which is threadedly connected to the base 10; a connecting post 30, which extends axially along the center point of the protective cover 20 and is located on the side of the protective cover 20 away from the base 10; and a connector, one end of which is located on the base 10 and the other end of which is rotatably fitted onto the connecting post 30.

[0038] Specifically, the base 10 is a container used for assembly, and the protective cover 20 seals the container of the base 10, thereby effectively preventing leakage of internal substances and achieving a sealing effect. The protective cover 20 and the base 10 are connected by threads. During installation, simply align the protective cover 20 with the base 10, and rotate the protective cover 20 to engage with the threads of the base 10 to achieve a tight connection.

[0039] Furthermore, the connecting post 30 provides a rotatable support point for the connector, allowing the connector to rotate freely around the connecting post 30. The connecting post 30 is positioned at the axial extension of the center point, ensuring, on the one hand, that the space around the connecting post 30 is relatively uniform during the rotational disassembly of the protective cover 20, preventing additional torque or wobbling caused by eccentric positioning, thus making the disassembly process smoother; on the other hand, the connector is not interfered with by the edge structure of the protective cover 20 when rotating around it, avoiding the problem of traction rope entanglement caused by the connecting post 30 being positioned on the edge side, thereby greatly reducing disassembly resistance and improving disassembly efficiency.

[0040] Furthermore, the connector is a structure with a rope or chain, which can be rigid or flexible. The connector prevents the protective cover 20 from being lost or falling off after it is completely detached from the base 10, ensuring that the protective cover 20 remains connected to the base 10 at all times. Simultaneously, its rotatable characteristic allows the connector to rotate flexibly with the protective cover 20 during disassembly or installation operations when the protective cover 20 rotates relative to the base 10, without hindering the rotational movement of the protective cover 20, thus facilitating the disassembly of the protective cover 20.

[0041] In summary, when it is necessary to remove the protective cover 20, rotate the protective cover 20 in the opposite direction to gradually separate it from the threads of the base 10. During this process, the protective cover 20 rotates around its own axis, and the connecting post 30 remains at the center of the protective cover 20. The connector rotates freely around the connecting post 30 and will not move circumferentially with the rotation of the protective cover 20, thus avoiding the problem of the traction rope getting tangled. As the protective cover 20 continues to rotate, it will eventually completely separate from the base 10, but will still be connected to the base 10 through the connector and will not be lost.

[0042] In one specific embodiment, the connecting post 30 and the protective cover 20 are integrally connected.

[0043] Specifically, the integrated design makes the connecting post 30 and the protective cover 20 a whole, eliminating the risk of loosening or falling off between them. It can withstand greater external forces and rotational torque, and the structure and function are more tightly integrated, ensuring the reliability of the connection structure during long-term use.

[0044] In one specific embodiment, the connecting post 30 includes a rotating part 31 and a limiting part 32. One end of the rotating part 31 is disposed on the protective cover 20, and the other end is connected to the limiting part 32. The connecting member is sleeved on the rotating part 31.

[0045] Specifically, the rotating part 31 is the core component of the connecting column 30, providing a rotatable support track for the connector. It allows the connector to rotate freely around the rotating part 31 when the protective cover 20 rotates relative to the base 10, thus maintaining the connection between the protective cover 20 and the base 10 during disassembly without affecting normal rotation. The main function of the limiting part 32 is to axially limit the connector, preventing it from detaching from the rotating part 31 during rotation. The limiting part 32 ensures that the connector remains in the proper position on the rotating part 31, maintaining the connection between the protective cover 20 and the base 10.

[0046] In one specific embodiment, the diameter of the limiting part 32 is larger than the diameter of the rotating part 31.

[0047] Specifically, the diameter of the connector sleeved on the rotating part is smaller than the diameter of the limiting part 32. When the connector is sleeved on the rotating part 31, the limiting part 32 becomes a natural barrier, which can effectively prevent the connector from sliding along the axial direction of the rotating part 31 and detaching from the rotating part 31.

[0048] In one specific embodiment, the protective cover 20 has a circular structure.

[0049] Specifically, when rotating the protective cover 20, the contact surface between the hand and the protective cover 20 is a continuous curved surface, allowing the operator's hand to slide more smoothly on the surface of the protective cover 20 and apply rotational force. Compared to other structures with edges or polygons, the circular protective cover 20 reduces problems such as jamming and uneven resistance that may occur during rotation.

[0050] When a circular structure is subjected to external force, the force can be evenly distributed across the entire circumference. When the protective cover 20 is connected to the base 10 by threads, the friction, pressure and other external forces generated during rotation will act evenly on the edge of the circular protective cover 20, avoiding excessive local force that could cause deformation or damage to the protective cover 20.

[0051] In one specific embodiment, the base 10 has a connecting portion 11, which is along the base 10 and is disposed opposite to the protective cover 20, so that the connecting portion 11 extends into the protective cover 20.

[0052] Specifically, the connecting part 11 is a portion that protrudes and extends along the end face of the base 10, allowing the protective cover 20 to be fitted onto the protruding connecting part 11. The connecting part 11 enables the base 10 and the protective cover 20 to fit together structurally, providing a basic framework for their connection and ensuring accurate alignment in space, thus creating conditions for subsequent threaded connections.

[0053] In one specific embodiment, the protective cover 20 has a first threaded portion 21, which is disposed on the inner wall of the protective cover 20; the connecting portion 11 has a second threaded portion 111, which is disposed on the outer wall of the connecting portion 11, and the first threaded portion 21 and the second threaded portion 111 are connected in a cooperating manner.

[0054] Specifically, the connection between the first threaded portion 21 on the protective cover 20 and the second threaded portion 111 of the connecting portion 11 of the base 10 provides a specific connection structure, and the tight connection between the protective cover 20 and the base 10 is achieved through the engagement of the threads.

[0055] In one specific embodiment, the base 10 has a first fixing hole 12 and a second fixing hole 13, which are arranged adjacent to each other, and the connector passes through the first fixing hole 12 and the second fixing hole 13 in sequence.

[0056] Specifically, the adjacent first fixing hole 12 and second fixing hole 13 provide mounting points for the connector. After the connector passes through the two fixing holes, it is equivalent to forming two fixing points on the base 10, so that one end of the connector is fixed in the two fixing holes. When the protective cover 20 is rotated, the end connected to the protective cover 20 can rotate freely around the rotating part 31, while the other end of the connector serves as a fixing point to restrict the movement or loosening of the connector, thereby connecting the protective cover 20 and the base 10 and providing convenience for disassembly.

[0057] In one specific embodiment, the outer wall of the protective cover 20 also has anti-slip grooves 22.

[0058] Specifically, when a hand contacts the outer wall of the protective cover 20, the uneven structure of the anti-slip groove 22 increases the contact area and coefficient of friction between the hand and the protective cover 20. When applying a rotational force to open or close the protective cover 20, the friction between the hand and the anti-slip groove 22 can better resist the relative sliding tendency during rotation.

[0059] Therefore, the aforementioned anti-fall connection structure 100 is designed to consist of a base 10, a protective cover 20, a connecting post 30, and a connector. The protective cover 20 is threadedly connected to the base 10 to ensure a seal. The connecting post 30 extends axially along the center point of the protective cover 20 and is positioned away from the base 10. One end of the connector is fixed to the base 10, and the other end is rotatably fitted onto the connecting post 30. This allows the connector to both connect the protective cover 20 and the base 10, preventing the protective cover 20 from being lost or falling off after it is completely detached from the base 10, and also ensures that the connector can freely rotate around the connecting post 30 when the protective cover 20 and the base 10 rotate relative to each other, without generating excessive resistance to the rotation of the protective cover 20.

[0060] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
