Technical Field

[0001] The present invention relates to a pair-lock structure, specifically an anti-loosening pair-lock structure for frame assembly, belonging to the technical field of frame pair-locks. Background Art

[0002] A pair-lock is a connecting piece mainly used to connect a tricycle frame and a rear axle arm. While ensuring a firm and reliable connection between the rear axle arm and the frame, the rear axle arm can rotate slightly around the pair-lock as the axis to reduce the impact of vehicle bumps during driving on the frame and driving experience.

[0003] Traditional pair-lock structures are mostly composed of bolts, nuts, and two metal bushings. Although they can effectively connect the frame and the rear axle arm, there is a risk of the nut falling off after long-term use. Moreover, when disassembling and assembling the pair-lock structure, since the rear axle arm will squeeze the outer wall of the bushing, the disassembly and assembly operations of the pair-lock structure are relatively inconvenient. Therefore, an anti-loosening pair-lock structure for frame assembly is proposed. Summary of the Invention

[0004] In view of this, the present invention provides an anti-loosening pair-lock structure for frame assembly to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0042] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Embodiment 1

[0044] As Figures 1-7 shown, the embodiment of the present invention provides an anti-loosening locking structure for frame assembly, including a locking assembly 1 and an anti-loosening mechanism 2. The locking assembly 1 includes a locking bushing 101, a locking connecting piece 102, and a bolt column 103;

[0045] Among them, the locking connecting piece 102 is arranged on one side of the locking bushing 101. The outer sidewall of the bolt column 103 is slidably connected to the inner sidewalls of the locking bushing 101 and the locking connecting piece 102. The anti-loosening mechanism 2 is installed at one end of the bolt column 103. A docking auxiliary mechanism 3 is provided between the locking bushing 101 and the locking connecting piece 102. Plastic bushings 4 are sleeved on the outer sidewalls of the locking bushing 101 and the locking connecting piece 102;

[0046] Among them, the anti-loosening mechanism 2 is used to cooperate with the bolt column 103 to fasten the locking bushing 101 and the locking connecting piece 102, and has the functions of waterproofing and anti-loosening;

[0047] Among them, the docking auxiliary mechanism 3 uses changing magnetic poles to assist in the disassembly and assembly of the locking bushing 101 and the locking connecting piece 102.

[0048] In one embodiment, a locking groove 63 is opened at one end of the locking connecting piece 102 away from the locking bushing 101. One side of the inner sidewall of the locking groove 63 is fixedly connected with an airbag pad 62;

[0049] The anti-loosening mechanism 2 is wrapped by the airbag pad 62 in an inflated manner.

[0050] In one embodiment, the anti-loosening mechanism 2 includes a hexagonal nut 201, a metal gasket 202, a spring 203, and a baffle 204;

[0051] Among them, the inner wall of the hexagonal nut 201 is threadedly connected to one side of the outer wall of the bolt column 103. The metal gasket 202 is fixedly connected to the side of the inner wall of the hexagonal nut 201 away from the bolt column 103. One end of the spring 203 is fixedly connected to one side of the metal gasket 202, and the baffle 204 is fixedly connected to the other end of the spring 203. The hexagonal nut 201 uses a hemming process to fix the metal gasket 202 inside it;

[0052] The hexagonal nut 201 is connected to the bolt column 103 by threads. By rotating the hexagonal nut 201 using the threads, the hexagonal nut 201 slides into the locking groove 63 to squeeze the airbag pad 62. At the same time, the moving hexagonal nut 201 uses the metal gasket 202 and the spring 203 to drive the baffle 204 to squeeze one end of the bolt column 103, so that the spring 203 is compressed under the action of pressure. In order to use the compressed spring 203, the baffle 204 and the metal gasket 202 to provide a reverse thrust between the bolt column 103 and the hexagonal nut 201 to increase the friction between the threads of the bolt column 103 and the hexagonal nut 201.

[0053] In one embodiment, the docking auxiliary mechanism 3 includes a first sleeve 301, a plurality of first magnetic blocks 302, a second sleeve 303 and a plurality of second magnetic blocks 304;

[0054] Among them, a storage groove 5 is opened at one end of the locking bushing 101. One end of the first magnetic block 302 is fixedly connected to one side of the inner wall of the storage groove 5. The second sleeve 303 is fixedly connected to one end of the locking connector 102. A plurality of first magnetic blocks 302 are fixedly connected to the inner wall of the first sleeve 301, and the magnetic poles of the plurality of first magnetic blocks 302 are arranged staggeredly. A plurality of second magnetic blocks 304 are fixedly connected to the inner wall of the second sleeve 303, and the magnetic poles of the plurality of second magnetic blocks 304 are arranged staggeredly. The outer walls of the second sleeve 303 and the locking connector 102 are slidably connected to the inner wall of the storage groove 5;

[0055] When one end of the locking connector 102 extends into the storage groove 5, the locking bushing 101 and the locking connector 102 are attracted by the first magnetic block 302 and the second magnetic block 304 by magnetic attraction;

[0056] When it is necessary to disassemble the locking bushing 101 and the locking connector 102, the bolt column 103 is rotated to drive the locking bushing 101 to rotate. The rotating locking bushing 101 drives the annularly distributed first magnetic blocks 302 to rotate through the first sleeve 301, so that the adjacent magnetic poles of the first magnetic block 302 and the second magnetic block 304 are changed. The changed magnetic poles provide a continuous thrust between the locking bushing 101 and the locking connector 102 to assist in the disassembly operation.

[0057] In one embodiment, a sealant 61 is coated between the hexagonal nut 201 and the metal gasket 202;

[0058] The provided sealant 61 is used to improve the waterproof seal between the hexagonal nut 201 and the metal gasket 202.

[0059] When the present invention is in operation: When it is necessary to use the locking structure to connect the tricycle frame and the rear axle arm, first, move the locking bushing 101 to drive the plastic bushing 4 into the mounting hole of the frame, and extend one end of the locking bushing 101 into the mounting hole of the rear axle arm. Then, move the locking connector 102 to drive the plastic bushing 4 into the mounting hole on the other side of the frame, and extend one end of the locking connector 102 into the storage groove 5, so as to magnetically attract the locking bushing 101 and the locking connector 102 by means of the first magnet 302 and the second magnet 304.

[0060] After the locking bushing 101 and the locking connector 102 are installed, move the bolt column 103 through the locking bushing 101 and extend it to one side of the locking connector 102. Then, connect the hexagonal nut 201 to the bolt column 103 by means of threads, and rotate the hexagonal nut 201 by means of threads to make the hexagonal nut 201 slide into the locking groove 63 to squeeze the airbag pad 62. At the same time, the moving hexagonal nut 201 drives the baffle 204 to squeeze one end of the bolt column 103 by means of the metal gasket 202 and the spring 203, so that the spring 203 is compressed under the action of pressure, so as to use the compressed spring 203 in cooperation with the baffle 204 and the metal gasket 202 to provide a reverse thrust between the bolt column 103 and the hexagonal nut 201 to increase the friction between the threads of the bolt column 103 and the hexagonal nut 201; After the bolt column 103 and the hexagonal nut 201 are tightened, use the deformed airbag pad 62 to wrap the outer wall of the hexagonal nut 201 to prevent water from seeping into the threads between the hexagonal nut 201 and the bolt column 103 and increase the resistance when the hexagonal nut 201 loosens, which not only improves the protection of the threads, but also further improves the loosening prevention effect and ensures the overall service life of the locking structure.

[0061] Embodiment 2

[0062] As Figures 1-12 shown, the embodiment of the present invention provides a locking and loosening prevention structure for frame assembly, including a locking assembly 1 and a loosening prevention mechanism 2. The locking assembly 1 includes a locking bushing 101, a locking connector 102 and a bolt column 103;

[0063] Among them, the pair-lock connecting piece 102 is arranged on one side of the pair-lock bushing 101. The outer sidewall of the bolt column 103 is slidably connected to the inner sidewalls of the pair-lock bushing 101 and the pair-lock connecting piece 102. The anti-loosening mechanism 2 is installed at one end of the bolt column 103. A docking auxiliary mechanism 3 is arranged between the pair-lock bushing 101 and the pair-lock connecting piece 102. Plastic bushings 4 are sleeved on the outer sidewalls of the pair-lock bushing 101 and the pair-lock connecting piece 102;

[0064] Among them, the anti-loosening mechanism 2 is used to cooperate with the bolt column 103 to fasten the pair-lock bushing 101 and the pair-lock connecting piece 102, and has the functions of waterproofing and anti-loosening;

[0065] Among them, the docking auxiliary mechanism 3 uses the changing magnetic poles to assist in the disassembly and assembly of the pair-lock bushing 101 and the pair-lock connecting piece 102.

[0066] The difference from the first embodiment is that a warning mechanism 7 is arranged on one side of the hexagon nut 201. The warning mechanism 7 includes a circular housing 701, an active buzzer 702, a battery holder 703, a button battery 704, and a thimble 705;

[0067] Among them, the circular housing 701 is fixedly connected to one side of the metal gasket 202. The active buzzer 702 is installed on one side of the inner sidewall of the circular housing 701. The battery holder 703 is installed on the other side of the inner sidewall of the circular housing 701. The button battery 704 is installed on the inner sidewall of the battery holder 703. One end of the thimble 705 is fixedly connected to one side of the baffle 204. The other end of the thimble 705 penetrates through the metal gasket 202 and the inner sidewall of the circular housing 701 and extends into the battery holder 703;

[0068] The battery holder 703 is composed of an insulating seat 731, a metal tongue 732, a reed 733, a power connection tongue 734, and an electrode plate 735;

[0069] Among them, the insulating seat 731 is fixedly connected to one side of the inner sidewall of the circular housing 701. The outer sidewall of the button battery 704 is slidably connected to the inner sidewall of the insulating seat 731. The electrode plate 735 is fixedly connected to one side of the inner sidewall of the insulating seat 731. The power connection tongue 734 is fixedly connected to the other side of the inner sidewall of the insulating seat 731. The metal tongue 732 is fixedly connected to the side of the insulating seat 731 away from the active buzzer 702. The reed 733 is fixedly connected to the side of the metal tongue 732 close to the power connection tongue 734. One end of the thimble 705 penetrates through the inner sidewall of the power connection tongue 734 and abuts against one side of the reed 733. A sealant 61 is coated between the hexagon nut 201, the metal gasket 202, and the circular housing 701;

[0070] The sealant 61 provided is used to improve the waterproof seal between the hexagon nut 201, the metal gasket 202, and the circular housing 701

[0071] When the spring 203 is compressed under the action of pressure, the hexagonal nut 201 in motion cooperates with the metal gasket 202 to drive the entire circular housing 701 to move, so that one end of the ejector pin 705 can penetrate through the metal gasket 202, the circular housing 701 and the electrical contact tongue 734, and squeeze one side of the reed 733, causing it to separate from the electrical contact tongue 734 under the action of pressure, so as to cut off the circuit between the button battery 704 and the active buzzer 702 while using the bolt column 103 and the hexagonal nut 201 to lock the locking bushing 101 and the locking connector 102.

[0072] When the hexagonal nut 201 becomes loose after long-term use, the compressed spring 203 is used to push the baffle 204 to move. The moving baffle 204 drives the ejector pin 705 to move. The moving ejector pin 705 relieves the extrusion of one side of the reed 733, causing it to reset and contact the electrical contact tongue 734 under the action of elasticity, thereby forming a circuit between the button battery 704 and the active buzzer 702, so as to start the active buzzer 702 for early warning, so that when the locking structure becomes loose, it can be discovered and processed in time, avoiding safety accidents caused by the loosening of the locking structure.

[0073] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
