Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a universal hinge support for steel structures of buildings. Background Technology

[0002] Universal joint supports are indispensable key connecting components in steel structures, primarily used to connect beams, columns, and other major load-bearing structural members. Their core function is to allow structural members to rotate and displace to a certain extent under load, thereby effectively releasing stress, preventing structural damage due to stress concentration, and significantly improving the overall safety and stability of the structure. Traditional universal joint supports typically consist of core components such as an upper support plate, a lower support plate, a ball joint, and a pin. These components work together to ensure that the support can rotate flexibly in multiple directions to adapt to complex stress conditions.

[0003] Currently, in practical engineering applications, universal joint supports are subjected to repeated loads from various sources, including structural weight, wind loads, and seismic forces, while also facing the corrosive effects of external environmental factors such as temperature changes, humidity, and corrosive media. The combined effect of these factors makes the rotating parts of the universal joint support prone to wear and corrosion. Over time, the accumulation of wear leads to a decline in the support's rotational performance, manifesting as inflexible rotation, increased friction, and even jamming. This not only affects the structure's normal deformation capacity but may also cause stress concentration, thereby threatening the overall structural safety and durability and shortening its service life.

[0004] To address these issues, we provide a universal hinge support for steel structures in buildings. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a universal hinge support for steel structures of buildings, including a ball seat and a universal ball that can rotate in any direction by conforming to the inner wall of the ball seat. A push shaft is fixed on the surface of the universal ball. A storage chamber for storing lubricating grease is opened at the center of the ball seat. Several through holes communicating with the inside of the storage chamber are opened on the inner wall of the ball seat. Several Y-shaped channels are evenly distributed in a circular array inside the ball seat. The three ends of the Y-shaped channels are respectively connected to the external environment, the storage chamber and the inner wall of the ball seat. One-way valves are respectively set on the inner wall of the Y-shaped channels near the outside and the storage chamber, so that air can only enter from the outside in one direction through one of the one-way valves and enter the storage chamber in one direction through the other one-way valve. A piston plate is horizontally slidably arranged on the inner wall of the Y-shaped channels between the two one-way valves. A spring that can pull the piston plate is fixed on the inner wall of the ball seat.

[0006] The present invention is further configured such that a piston rod pointing horizontally toward the push shaft is fixed coaxially to the side of the piston plate, and a actuating ball is fixed to one end of the piston rod near the push shaft, the outer surface of the actuating ball being in contact with the circumferential side of the push shaft.

[0007] The present invention is further configured such that a mounting plate is fixed on the circumferential side of the piston rod near the actuating ball, the spring is fixed between the inner wall of the ball seat and the mounting plate, and the spring is sleeved on the circumferential side of the piston rod.

[0008] The present invention is further configured such that, when the push shaft is placed vertically, the vertical distance between its circumferential side and the inner wall of the ball seat is less than half the length of the push shaft, so as to prevent the push shaft from deflecting excessively.

[0009] The present invention is further configured such that a horizontally arranged load-bearing plate is fixed at the top of the push shaft, a steel structure column is fixed on the surface of the load-bearing plate, and a base is fixed at the bottom of the ball seat.

[0010] The present invention has the following beneficial effects: 1. The present invention controls the direction of gas by setting a one-way valve and controls the return of the piston plate by a spring, so that the gas pressure inside the storage chamber will not be affected after the piston plate returns to its original position each time. Then, when the push shaft deflects in the same direction the next time, it can move immediately to achieve the supply of lubricating grease, avoid the steel structure column from getting stuck when rotating, and thus maintain the timely supply of lubricating grease.

[0011] 2. This utility model can generate a force on the push shaft by setting a spring. When the push shaft deflects, the spring will push the push shaft in the opposite direction, which will limit the rotation of the push shaft to a certain extent and maintain the stability of the steel structure column.

[0012] 3. The through hole of this utility model is evenly distributed outward from the center of the inner bottom surface of the ball seat, so that the lubricating grease first adheres to the bottom of the universal ball, and then slowly spreads in all directions as the universal ball rotates, so that when the universal ball rotates in any direction, there is lubricating grease to smooth its rotation path and improve the flexibility of the universal ball.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0023] Please see Figure 1-4 This utility model is a universal hinge support for steel structures of buildings, including a ball seat 1 and a universal ball 2 that can rotate in any direction by conforming to the inner wall of the ball seat 1. A push shaft 3 is fixed on the surface of the universal ball 2, and a horizontally arranged load-bearing plate 13 is fixed at the top of the push shaft 3. A steel structure column 14 is fixed on the surface of the load-bearing plate 13, and a base 15 is fixed at the bottom of the ball seat 1.

[0024] Specifically, the entire device is supported by the base 15. When the steel structure column 14 rotates, it will drive the load-bearing plate 13 and the push shaft 3 to rotate, which in turn will drive the universal ball 2 to rotate on the inner wall of the ball seat 1. The ball design of the universal ball 2 and the ball design of the inner wall of the ball seat 1 allow the universal ball 2 to rotate in any direction, further improving the flexibility of the steel structure column 14 to deflect.

[0025] Specifically, when the push shaft 3 is placed vertically, the vertical distance between its circumferential side and the inner wall of the ball seat 1 is less than half the length of the push shaft 3, to prevent the push shaft 3 from deflecting excessively.

[0026] Specifically, the inner cavity of the ball seat 1 provides a certain deflection space for the push shaft 3, but limits its maximum deflection angle to prevent the push shaft 3 from deflecting too much and affecting the stability of the building, so that the device can maintain its own stability when the building is deformed.

[0027] Furthermore, a storage chamber 4 for storing lubricating grease is provided at the center of the ball seat 1, and several through holes 5 communicating with the interior of the storage chamber 4 are provided on the inner wall of the ball seat 1.

[0028] Specifically, the through hole 5 connects the storage compartment 4 and the inner cavity of the ball seat 1. Lubricating grease can enter the inner cavity of the ball seat 1 through the through hole 5. The through hole 5 is close to the center of the inner bottom surface of the ball seat 1 and expands outward evenly. This allows the lubricating grease to first adhere to the bottom of the universal ball 2, and then slowly spread outward as the universal ball 2 rotates. This ensures that when the universal ball 2 rotates in any direction, there is lubricating grease to smooth its rotation path, improving the flexibility of the universal ball 2.

[0029] Furthermore, the ball seat 1 has several Y-shaped channels 6 evenly distributed in a circular array inside. The three ends of the Y-shaped channels 6 are connected to the external environment, the storage compartment 4 and the inner wall of the ball seat 1, respectively. One-way valves 7 are respectively installed on the inner wall of the Y-shaped channels 6 near the outside and the storage compartment 4.

[0030] A piston plate 8 is horizontally slidably arranged on the inner wall of the Y-shaped channel 6 between the two one-way valves 7, and a spring 9 that can pull the piston plate 8 to move is fixed on the inner wall of the ball seat 1.

[0031] A piston rod 10 is fixed coaxially to the side of the piston plate 8, pointing horizontally towards the push shaft 3. A pawl ball 11 is fixed to one end of the piston rod 10 near the push shaft 3, and the outer surface of the pawl ball 11 fits against the periphery of the push shaft 3.

[0032] A mounting plate 12 is fixed to the side of the piston rod 10 near the actuating ball 11. A spring 9 is fixed between the inner wall of the ball seat 1 and the mounting plate 12. The spring 9 is sleeved on the side of the piston rod 10.

[0033] Specifically, the spring 9 exerts a force on the push shaft 3. When the push shaft 3 deflects, the spring 9 will exert a thrust in the opposite direction on the push shaft 3, which will limit the rotation of the push shaft 3 to a certain extent and maintain the stability of the steel structure column 14.

[0034] When the steel column 14 deflects, the push shaft 3 deflects accordingly, which in turn pushes the actuating ball 11 and piston rod 10 in the direction of deflection. This, in turn, pushes the piston plate 8 to slide inside the Y-shaped channel 6, compressing the gas inside the Y-shaped channel 6. The gas then enters the storage chamber 4 through the one-way valve 7 near the storage chamber 4, squeezing out the lubricating grease inside the storage chamber 4 through the through hole 5. When the push shaft 3 deflects in another direction, the spring 9 pulls the piston plate 8 back, allowing the Y-shaped channel 6 to draw in gas from the outside through another one-way valve 7. This keeps the actuating ball 11 in contact with the push shaft 3. Thus, when the push shaft 3 deflects in the same direction again, any displacement will squeeze out the lubricating grease, thereby maintaining the flexibility of rotation.

[0035] Furthermore, the interior of the ball seat 1 is evenly distributed with several Y-shaped channels 6 in a circular array. The three ends of the Y-shaped channels 6 are connected to the external environment, the storage compartment 4 and the inner wall of the ball seat 1, respectively.

[0036] One-way valves 7 are respectively installed on the inner wall of the Y-shaped channel 6 near the outside and the storage compartment 4, so that air can only enter from the outside in one direction through one of the one-way valves 7 and enter the storage compartment 4 in one direction through the other one-way valve 7.

[0037] Specifically, when the push shaft 3 deflects and pushes the actuating ball 11, the piston plate 8 pushes the air into the storage chamber 4, which increases the air pressure inside the storage chamber 4 and pushes the lubricating grease inside the storage chamber 4 to move outward, squeezing the lubricating grease out of the through hole 5 and making it come into contact with the universal ball 2. At this time, the amount of lubricating grease inside the storage chamber 4 will decrease. In order to maintain the air pressure inside the storage chamber 4, the one-way valve 7 cannot release the gas inside the storage chamber 4. At this time, the lubricating grease inside the storage chamber 4 is in contact with the through hole 5. Then, when air enters the storage chamber 4 from other Y-shaped channels 6, the lubricating grease inside the storage chamber 4 immediately moves outward through the through hole 5 and is squeezed out.

[0038] If the actuating ball 11 remains in its deflected position after each deflection and does not return to the correct position, or if the one-way valve 7 does not control the one-way flow of gas inside the storage chamber 4, then the gas will be drawn back after the piston plate 8 returns to its original position each time. In this case, when the push shaft 3 deflects in the same direction next time, the push shaft 3 needs to deflect at a larger angle to push the actuating ball 11 to move and supply lubricating grease, which may cause jamming, affect the rotation of the steel structure column 14, and thus fail to maintain the timely supply of lubricating grease.
