Technical Field

[0001] This invention relates to the field of connection structure technology, and more specifically to a frame with continuous corner positions. Background Technology

[0002] At the corners of panel structures such as desks, two crossbars are usually joined together. The connection between the two crossbars cannot fit perfectly, resulting in gaps at the corners, which affects both aesthetics and connection strength.

[0003] Moreover, the existing corner connection structure is very inconvenient to use. It is fixed by using threaded fasteners, which require a large number of fasteners, making installation complicated. Once it loosens, repair is also quite troublesome. Summary of the Invention

[0004] 1. The technical problem that the invention aims to solve

[0005] The purpose of this invention is to solve the technical problems existing in the prior art and provide a frame with continuous corner positions. It can replace the connection gap between the two traditional connectors with the surface, which is more aesthetically pleasing and can effectively improve the connection strength between two adjacent connectors. Moreover, the connection tightness between all the connecting rods and corner connectors can be adjusted at the same time by pulling the rope, which makes installation and repair very convenient.

[0006] 2. Technical Solution

[0007] To solve the above problems, the technical solution provided by the present invention is as follows:

[0008] A frame with continuous corner positions includes an annular frame body. The frame body includes several connecting rods and several corner connectors. The corner connectors are used to connect two adjacent connecting rods. The outer side wall of each corner connector has a continuous surface. The connecting rods and corner connectors are positioned and connected by a plug-in structure. One of the corner connectors is a main corner connector. A pull rope is connected to the main corner connector. A rotating component is provided inside the main corner connector. The connecting rods and the remaining corner connectors are provided with rope grooves that allow the pull rope to pass through. The other end of the pull rope passes through the corner connector and the connecting rod and is connected to the rotating component. The frame also includes a control structure for controlling the rotation of the rotating component.

[0009] Optionally, the control structure includes a magnetic block disposed outside the main corner connector and magnetically engaged with the rotating component.

[0012] Optionally, one end of the rotating component is provided with a first movable magnetic block and a second movable magnetic block. The second movable magnetic block is annular and surrounds the first movable magnetic block. The end of the rotating component is provided with a first movable groove for accommodating the first movable magnetic block. The first movable magnetic block is connected to the rotating component by a first elastic telescopic structure to prevent rotation and to move back and forth. A plurality of first limiting posts are arranged on the circumference of the end of the first movable magnetic block facing away from the rotating component. The main corner connector is provided with a plurality of first limiting grooves that cooperate with the first limiting posts. The main corner connector is provided with a second movable groove for accommodating the second movable magnetic block.

[0013] Optionally, the corner connector has two connecting protrusions, and the end of the connecting rod has a connecting slot that mates with the connecting protrusions.

[0014] Optionally, a sealing gasket is fitted onto the connecting protrusion, and the sealing gasket abuts between the connecting rod and the corner connector.

[0015] Optionally, the pull rope is a steel wire rope.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0018] This corner connection structure connects two adjacent connectors via the corner connector, and replaces the traditional gap between two connectors with the face, resulting in a more aesthetically pleasing appearance and effectively improving the connection strength between adjacent connectors. Furthermore, during the assembly of the frame body, the tightness of all connecting rods and corner connectors can be adjusted simultaneously by pulling ropes. Compared to using fasteners to connect each connecting rod and corner connector individually, this method is more convenient. Moreover, if the connection becomes loose during use, the connection can be restored by rotating the rotating component, allowing for repair even if the user is unaware of the specific location of the loosening.

[0028] Combined with appendix Figure 1-4 This embodiment provides a frame with continuous corner positions, comprising a ring-shaped frame body (in this embodiment, the frame body has a rectangular ring structure), the frame body including several connecting rods (not shown in the figure, the position between two corner connectors 2 in the figure is where the connecting rods are installed) and several corner connectors 2, the corner connectors 2 being used to connect two adjacent connecting rods, the outer side wall of the corner connector 2 having a continuous surface 2a, the surface 2a having no gaps and being a smooth bent surface (in this embodiment, the surface 2a is a continuous right-angled surface), the connecting rods and the corner connectors 2 being positioned and connected by a plug-in structure, wherein one of the corner connectors... Component 2 is the main corner connector 3, and the other corner connectors 2 have the same structure. A pull rope 4 is connected to the main corner connector 3. A rotating component 5 is provided inside the main corner connector 3. The rotating component 5 is rotatably assembled inside the main corner connector 3. The main corner connector 3 has a cavity for installing the rotating component 5. The connecting rod and the other corner connectors 2 all have rope grooves that allow the pull rope 4 to pass through. The pull rope 4 passes through the other corner connectors 2 and all the connecting rods in sequence along the annular direction of the frame body and then connects to the rotating component 5. It also includes a control structure for controlling the rotation of the rotating component 5.

[0029] This corner connection structure connects two adjacent connectors 1 through the corner connector 2, and replaces the traditional connection gap between two connectors 1 with the surface 2a, resulting in a more aesthetically pleasing appearance and effectively improving the connection strength between adjacent connectors 1. Furthermore, during the assembly of the frame body, the connection tightness between all connecting rods and corner connectors 2 can be adjusted simultaneously using the pull rope 4. Compared to using fasteners to connect each connecting rod and corner connector 2, this method is more convenient. Moreover, if the connection becomes loose during use, the connection can be restored by rotating the rotating part 5, allowing for repair even if the user is unaware of the specific location of the loosening.

[0030] As an optional embodiment of the present invention, the control structure includes a magnetic block 6 disposed outside the main corner connector 3 and magnetically engaged with the rotating member 5. The magnetic engagement not only simplifies the control structure but also prevents the pull rope 4 from becoming overly taut due to the excessive angle of the rotating member 5. When the pulling force on the rotating member 5 from the pull rope 4 is greater than the magnetic attraction between the rotating member 5 and the magnetic block 6, the magnet 6 can no longer control the rotation of the rotating member 5.

[0031] As an optional solution of the present invention, in order to prevent the rotating member 5 from rotating in the opposite direction and causing the pull rope 4 to loosen, and to avoid the user from rotating the rotating member 5 in the opposite direction during operation, the main corner connector 3 is provided with a one-way structure that allows the rotating member 5 to rotate only in one direction; specifically, the one-way structure includes a one-way toothed ring 7 provided on the outer peripheral wall of the rotating member 5 and a one-way toothed groove 8 provided on the main corner connector 3. The one-way toothed ring 7 is assembled in the one-way toothed groove 8, and the one-way toothed ring 7 can only rotate circumferentially in the same direction in the one-way toothed groove 8. Of course, the positions of the one-way toothed ring 7 and the one-way toothed groove 8 on the rotating member 5 and the main corner connector 3 can be interchanged.

[0032] As an optional solution of the present invention, in order to ensure that the tension of the pull rope 4 when taut is sufficient to guarantee the forming of the frame body and extend the service life of the pull rope 4, the pull rope 4 is a steel wire rope.

[0033] As an optional embodiment of the present invention, one end of the rotating member 5 is provided with a first movable magnet 9 and a second movable magnet 10. The first movable magnet 9 has a circular structure, and the second movable magnet 10 is annular and surrounds the first movable magnet 9. The end of the rotating member 5 is provided with a first movable groove 11 for accommodating the first movable magnet 9. The first movable groove 11 is formed by an inward recess from the end of the rotating member 5. One end of the first movable magnet 9 can extend from the opening side of the first movable groove 11. The first movable magnet 9 is prevented from rotating by a first elastic telescopic structure and is connected to the rotating member 5 in a reciprocating manner. On the rotating member 5, the first elastic telescopic structure includes an elastic telescopic rod for connecting the first movable magnet 9 and the rotating member 5. A plurality of first limiting posts 12 are arranged circumferentially on the first movable magnet 9 at one end opposite to the rotating member 5. The main corner connector 3 is provided with a plurality of first limiting grooves 13 that cooperate with the first limiting posts 12. The elastic force generated by the first elastic telescopic structure drives the first limiting posts 12 on the first movable magnet 9 to insert into the first limiting grooves 13 to restrict the relative rotation of the rotating member 5 and the main corner connector 3. The two movable magnets 18 abut against the... At the end of the rotating component 5, the main corner connector 3 is provided with a second movable groove 14 for accommodating the second movable magnetic block 10. The second movable magnetic block 10 is connected to the main corner connector 3 by a second elastic telescopic structure that prevents rotation and allows it to move back and forth. The second elastic telescopic structure includes an elastic telescopic rod for connecting the second movable magnetic block 10 and the main corner connector 3. A plurality of second limiting posts 15 are arranged circumferentially on the second movable magnetic block 10 near one end of the rotating component 5. The rotating component 5 is provided with a plurality of second limiting grooves 16 that cooperate with the second limiting posts 15. The second elastic telescopic structure... The elastic force generated by the structure drives the second limiting post 15 on the second movable magnetic block 10 to insert into the second limiting groove 16, further achieving the purpose of restricting the relative rotation of the rotating member 5 and the main corner connector 3; the first movable magnetic block 9 and the second movable magnetic block 10 have the same polarity at the end that cooperates with the magnetic block 6; the magnetic block 6 includes a first magnetic block 61 that is repulsed by the first movable magnetic block 9 and a second magnetic block 62 that is attracted by the second movable magnetic block 10; the first magnetic block 61 and the second magnetic block 62 can be fixed together by a magnetic shielding plate, and the second magnetic block 62 is arranged around the first magnetic block 61;In actual operation, when the first magnetic block 61 approaches the first movable magnetic block 9, due to the principle of like poles repelling, it pushes the first movable magnetic block 9 into the first movable slot 11, causing the first limiting post 12 to disengage from the first limiting slot 13 for the first unlocking step. Simultaneously, when the second magnetic block 62 approaches the second movable magnetic block 10, due to the principle of opposite poles attracting, it attracts the second movable magnetic block 10 into the second movable slot 14, causing the second limiting post 15 to disengage from the second limiting slot 16 for the second unlocking step. In this state, the magnetic block 6 controls the rotation of the rotating component 5 through magnetic attraction with the rotating component 5, which is made of a metal that attracts magnets. This structural design effectively prevents children or other users from using ordinary magnets, thus avoiding connection failure of the main frame.

[0034] As an optional solution of the present invention, the corner connector 2 is provided with two connecting protrusions 17, and the end of the connecting rod is provided with a connecting slot that mates with the connecting protrusions 17. When the connecting protrusions 17 are inserted into the connecting slot, the pre-positioning between the corner connector 2 and the connecting rod can be achieved, and the connection position between the corner connector 2 and the connecting rod can be ensured to remain unchanged when the pull rope 4 is taut.

[0035] As an optional solution of the present invention, in order to ensure the sealing of the connection between the connector 1 and the corner connector 2 and to compensate for the gap between the connector 1 and the corner connector 2, a sealing gasket is provided between the connector 1 and the corner connector 2. The sealing gasket is sleeved on the connecting protrusion 4 and the sealing gasket is a rubber gasket.

[0036] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
