Description

Technical Field

[0001] The present invention relates to the technical field of fastening components, and in particular to a cargo transportation device and an anti-loosening and anti-detaching fastening belt assembly for building structures. Background Art

[0002] In the field of cargo transportation, ensuring the stability of goods during transportation is crucial for guaranteeing transportation safety and the integrity of goods. Traditional fixing methods, such as bundling with ordinary ropes, connecting with simple chains or fastening with ordinary bolts, have poor fixing effects when facing frequent vibrations, bumps and sudden brakes during transportation. The goods are extremely likely to be displaced, collided or even dropped, which not only causes damage to the goods, but may also lead to serious safety accidents.

[0003] In terms of building structures, especially with the increasing popularity of prefabricated buildings and the growing requirements for seismic and wind resistance performance of buildings, the traditional connection methods of bolts and nuts have exposed many problems. After being subjected to external forces such as earthquakes and winds for a long time, the connection parts are prone to looseness, which greatly threatens the structural safety of the buildings. For the above reasons, this application proposes a cargo transportation device and an anti-loosening and anti-detaching fastening belt assembly for building structures. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a cargo transportation device and an anti-loosening and anti-detaching fastening belt assembly for building structures.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An anti-loosening and anti-detaching fastening belt assembly for a cargo transportation device and a building structure includes a locking bolt, a nut, a gasket, an upper pressing plate and a lower pressing plate, and further includes a metal anti-loosening piece. A strip-shaped groove is formed in the circumferential side wall of the locking bolt. The strip-shaped groove is a through groove that penetrates the side wall of the locking bolt, and the top and bottom of the strip-shaped groove are both flat structures;

[0007] The metal anti-loosening piece has a right-angled trapezoid structure. When in use, the metal anti-loosening piece and the nut of the locking bolt are respectively arranged on both sides of the nut, and the right-angled side of the metal anti-loosening piece is inserted into the strip-shaped groove in contact with the surface of the nut, and the inclined surface of the metal anti-loosening piece abuts against the top of the strip-shaped groove, so as to apply a pre-tightening pressure to the nut to prevent the nut from loosening.

[0008] Preferably, the gasket is an O-shaped gasket.

[0009] Preferably, the gasket is a spiral gasket.

[0010] Preferably, the upper surface of the upper half of the spiral gasket is provided with a plurality of clamping points, and the lower surface of the nut is provided with a plurality of grooves adapted to the clamping points.

[0011] Preferably, a plurality of inclined teeth are provided on the lower surface of the upper half of the spiral gasket, and a plurality of inclined tooth grooves are provided on the upper surface of the lower half of the spiral gasket. The inclined teeth can enter and exit the inclined tooth grooves in the clockwise direction.

[0012] Preferably, a push-pull bar is fixedly connected to the end of the lower half of the spiral gasket, and a fixing plate is arranged on the lower surface of the push-pull bar.

[0013] Preferably, a spring is fixedly connected to the side wall of the fixing plate close to the upper pressing plate, and one end of the spring away from the fixing plate is fixedly connected to the side wall of the upper pressing plate.

[0014] Preferably, a damping rod is fixedly connected to the side wall of the fixing plate, an exhaust groove is formed in the side wall of the upper pressing plate, and the damping rod is slidably arranged in the exhaust groove.

[0015] Preferably, an exhaust hole communicating with the exhaust groove is formed in the side wall of the upper pressing plate. The connection part of the exhaust hole and the exhaust groove is a tapered section, and the end of the damping rod located in the exhaust groove is a tapered structure.

[0016] Preferably, through holes are formed on the surfaces of both the upper pressing plate and the lower pressing plate.

[0017] The present invention has the following beneficial effects:

[0018] 1. Based on the traditional bolt, spring washer, and nut fastening structure, the present invention opens a through strip groove on the circumferential side wall of the bolt, and at the same time adds a metal anti-loosening sheet. After the metal anti-loosening sheet is inserted into the strip groove, the inclined surface of the metal anti-loosening sheet squeezes the top of the strip groove to apply a pre-tightening force to the nut, and after the metal anti-loosening sheet is pressed tightly, the shorter side can be bent so that the short side curls to grip the circumference of the locking bolt, thereby effectively preventing the nut from loosening, and can effectively improve the stability effect of relevant connection components in truck transportation and building structure applications;

[0019] 2. By providing a spiral gasket, when the nut is tightened and presses the gasket, the upper half and the lower half of the spiral gasket can be pressed together to replace the O-shaped gasket. Compared with the fixed-structure O-shaped gasket, the spiral gasket can undergo a certain degree of deformation and has better elasticity. When applied to relevant connectors in truck transportation and building structures, when vibration occurs, it can effectively absorb part of the vibration kinetic energy and can effectively weaken the loosening effect caused by vibration;

[0020] 3. By adding inclined teeth and inclined tooth grooves to the spiral gasket, and the inclined teeth can freely enter and exit the inclined tooth grooves in the clockwise direction, it is convenient to tighten the nut, and in the counterclockwise direction, the inclined tooth grooves can catch the inclined teeth, which can increase the locking force of the spiral gasket in the counterclockwise direction and further prevent the nut from loosening;

[0021] 4. By setting up structures such as damping rods, springs, exhaust grooves, and exhaust holes, the elastic force of the spring, the frictional resistance between the damping rod and the inner wall of the exhaust groove, and the air resistance during exhaust can be utilized to further reduce the vibration amplitude transmitted to the device, thereby further weakening the loosening effect caused by vibration.

DETAILED DESCRIPTION OF THE INVENTION

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0035] Embodiment 1:

[0036] Referring to Figure 1 , a goods transportation device, an anti-loosening and anti-disengagement fastening belt assembly for building structures, a locking bolt 1, a nut 5, a gasket, an upper pressing plate 3 and a lower pressing plate 2. Through holes are provided on the surfaces of both the upper pressing plate 3 and the lower pressing plate 2. It also includes a metal anti-loosening piece 7. A strip-shaped groove 6 is provided on the circumferential side wall of the locking bolt 1. The strip-shaped groove 6 is a through groove and penetrates the side wall of the locking bolt 1. The top and bottom inside the strip-shaped groove 6 are both flat structures;

[0037] The metal anti-loosening piece 7 is in a right trapezoidal structure. When in use, the metal anti-loosening piece 7 and the nut of the locking bolt 1 are respectively arranged on both sides of the nut 5, and the right-angled side of the metal anti-loosening piece 7 is inserted into the strip-shaped groove 6 in contact with the surface of the nut 5, and the inclined surface of the metal anti-loosening piece 7 abuts against the top inside the strip-shaped groove 6, so as to apply a pre-tightening pressure to the nut 5 to prevent the nut 5 from loosening.

[0038] After the metal anti-loosening piece 7 is completely inserted and tightened, the short side of it is bent and curled along the circumferential direction of the locking bolt 1 and attached to the circumferential side of the bolt. This design further enhances the reliability of the fixation. After the short side of the metal anti-loosening piece 7 is curled, its up and down movement is restricted, preventing it from slipping out of the strip-shaped groove 6. In building construction, this stable fixation method can ensure that the connection parts of structures such as beams and columns still maintain a tight connection under long-term external forces, effectively improving the stability of the overall building structure and reducing the risk of safety accidents caused by connection loosening.

[0039] The gasket uses an O-shaped gasket 4.

[0040] As Figure 1 shown, in this embodiment, two components to be connected can be passed through the locking bolt 1 and placed between the upper pressing plate 3 and the lower pressing plate 2, and the nut 5 is tightened to press down the O-shaped gasket 4 and the upper pressing plate 3 to fix the two connected components.

[0041] After the nut 5 is tightened, the metal anti-loosening piece 7 is inserted into the strip-shaped groove 6, and the right-angled side of the metal anti-loosening piece 7 is attached to the upper surface of the nut 5. As the metal anti-loosening piece 7 is gradually inserted, its inclined surface can finally abut tightly against the top inside the strip-shaped groove 6, so as to apply a pre-tightening pressure to the lower nut 5 to prevent the nut 5 from loosening.

[0042] When the metal anti-loosening piece 7 is completely inserted and tightened, it can be as Figure 6As shown in the figure, along the circumferential direction (clockwise or counterclockwise) of the locking bolt 1, bend one side of the short edge of the metal lock washer 7 and make it curl and stick to the circumferential side of the locking bolt 1, so as to prevent the metal lock washer 7 from moving up and down. Figure 6 As shown in the figure, the short edge of the metal lock washer 7 curls so that it cannot move downward, and the long edge of the metal lock washer 7 abuts against the top of the strip-shaped groove 6 so that it cannot move upward. In this way, the nut can be effectively prevented from loosening, and the stability of the relevant connecting components can be effectively improved in truck transportation and building structure applications.

[0043] Embodiment 2:

[0044] Different from Embodiment 1, the gasket used is a spiral gasket 8.

[0045] During the truck transportation process, the uneven road surface will cause the vehicle to generate vibrations of various frequencies. The spiral gasket 8 can effectively absorb part of the vibration kinetic energy and reduce the energy transmitted to the connecting components. When passing through a speed bump or a potholed road surface, the elastic deformation of the spiral gasket 8 can buffer the impact force generated by the vibration and reduce the possibility of the nut 5 loosening, so as to better protect the fixed state of the goods.

[0046] In this embodiment, when the nut 5 is tightened and presses the gasket, the upper half and the lower half of the spiral gasket 8 can be pressed together to replace the use of the O-shaped gasket 4. Compared with the fixed-structured O-shaped gasket 4, the spiral gasket 8 can undergo a certain amount of deformation and has better elasticity. When applied to the relevant connectors in truck transportation and building structures, it can effectively absorb part of the vibration kinetic energy during vibration and can effectively weaken the loosening effect caused by vibration.

[0047] Embodiment 3:

[0048] Compared with Embodiment 1 and Embodiment 2, in this embodiment, a plurality of clamping points 15 are provided on the upper surface of the upper half of the spiral gasket 8, and a plurality of grooves 19 cooperating with the clamping points 15 are provided on the lower surface of the nut 5. A plurality of inclined teeth 17 are provided on the lower surface of the upper half of the spiral gasket 8, and a plurality of inclined tooth grooves 16 are provided on the upper surface of the lower half of the spiral gasket 8. The inclined teeth 17 can enter and exit the inclined tooth grooves 16 in the clockwise direction.

[0049] A push-pull bar 10 is fixedly connected to the end of the lower half of the spiral gasket 8, and a fixing plate 9 is arranged on the lower surface of the push-pull bar 10.

[0050] A damping rod 11 is fixedly connected to the side wall of the fixing plate 9, an exhaust groove 12 is provided on the side wall of the upper pressing plate 3, and the damping rod 11 is slidably arranged in the exhaust groove 12. An exhaust hole 18 communicating with the exhaust groove 12 is provided on the side wall of the upper pressing plate 3. The connection part of the exhaust hole 18 and the exhaust groove 12 is a tapered section 13, and the end of the damping rod 11 located in the exhaust groove 12 is a tapered structure.

[0051] When vibration forces the push-pull bar 10 to move horizontally back and forth, since it is connected to the spiral gasket 8, the connection between the upper and lower halves of the spiral gasket 8 will be made tighter. At the same time, the elastic force of the spring 14 and the frictional resistance between the damping rod 11 and the inner wall of the exhaust groove 12 can effectively absorb and buffer the vibration amplitude. The design of the exhaust hole 18 and the tapered section 13 further increases the air pressure resistance when the damping rod 11 moves, greatly weakening the impact of vibration on the device. When the truck is driving on a rough mountain road, these designs can effectively reduce the loosening of connections caused by vehicle jolts and ensure the safety of cargo transportation; when the house is hit by strong winds, it can also reduce the vibration of the structure and protect the stability of the house connection components.

[0052] In this embodiment, when the nut 5 is tightened and pressed down, the groove 19 on its lower surface will be in snap-fit contact with the snap point 15, so that the friction between the nut 5 and the spiral gasket 8 can be increased, and the connection stability effect between the two can also be improved.

[0053] Refer to Figure 10 and Figure 11 , when the nut 5 is further tightened, the upper and lower halves of the spiral gasket 8 will be compressed. Generally, the tightening direction of the nut 5 is clockwise. During the process of tightening the nut 5, it can also drive the spiral gasket 8 to contract along its spiral direction. The inclined teeth 17 can continuously disengage from the front inclined tooth groove 16 and enter the more rearward inclined tooth groove 16. In the loosening direction of the nut 5, that is, the counterclockwise direction, the inclined teeth 17 cannot disengage from the inclined tooth groove 16, thus effectively achieving the anti-loosening effect;

[0054] For easy understanding, refer to Figure 11 , when the upper half of the spiral gasket 8 moves leftward, the rightward inclined teeth 17 can leave the inclined tooth groove 16 of the lower half, and when the upper half of the spiral gasket 8 wants to move rightward, the inclined teeth 17 will be stuck by the inclined tooth groove 16 and cannot move.

[0055] In addition, when applying this device, the end of the push-pull bar 10 away from the locking bolt 1 can be welded to another connecting piece. When vibration occurs, such as the jolts during truck transportation, or the house structure is affected by earthquakes and wind forces, the vibration forces the restricted push-pull bar 10 to move horizontally back and forth. Since the push-pull bar 10 is connected to the spiral gasket 8, and the spiral gasket 8 can only move in one direction, the connection between the upper and lower halves of the spiral gasket 8 will be made tighter.

[0056] Furthermore, the elastic force of the spring 14 and the frictional resistance between the damping rod 11 and the inner wall of the exhaust groove 12 can effectively absorb and buffer the vibration amplitude, thereby reducing the impact of vibration on the device. In addition, by setting the exhaust hole 18 with a smaller aperture, and setting the tapered section 13 and the end of the damping rod 11 to a tapered structure, when the damping rod 11 continuously approaches the tapered section 13, the ventilation area can be greatly reduced, thereby increasing the air pressure resistance when the damping rod 11 moves. In this way, the vibration amplitude can be further reduced, effectively weakening the loosening effect caused by vibration.

[0057] The above is only a preferred specific embodiment 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, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
