[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The bottom end of the angle steel body is welded to the steel structure, and the top end of the angle steel body is welded to the steel structure. Affected by the welding of the top end of the angle steel body and the steel structure, the top end of the reinforcing rod is pressed against the steel structure. Affected by the steel structure, an extrusion effect is formed on the top end of the reinforcing rod, forcing the reinforcing rod to descend, and the reinforcing rod brings the pressure seat down, and the pressure seat pushes the vibration-damping spring to compress and shorten the vibration-damping spring. When the steel structure provides a load to the top end of the angle steel body, the load not only acts on the top end of the angle steel body, but also on the top end of the reinforcing rod, and then acts on the entire reinforcing rod from the top end of the reinforcing rod, and then acts on the pressure seat from the whole reinforcing rod, and then acts on the vibration-damping spring from the pressure seat, and then acts on the first reinforcing plate, and the vibration-damping spring is compressed and shortened again, and at the same time generates elastic force, thereby forming a vibration-damping effect on the load.

[0016] 2. A row of anti-bending rods 4 are arranged from top to bottom in the L-shaped cavity of the angle steel body 1, and the two ends of the anti-bending rods 4 are bent to the left and right sides of the angle steel body 1, which is equivalent to forming two supports in the width direction in the clamping cavity of the angle steel body 1. The two ends of the anti-bending rods 4 are used to provide supporting force to the left and right sides of the angle steel body 1, thereby preventing the angle steel body 1 from bending in the width direction, and also used to resist the shear force of the angle steel body 1 in the width direction, further improving the bending strength of the angle steel body.

[0017] 3. When the anti-bending rod moves downward, the anti-bending rod brings the first fastener and the second fastener down. The first fastener will not rotate when it is descending, but when the second fastener is descending, its first rotating plate will rotate, and the first rotating plate will bring the second rotating plate to rotate through a coaxial relationship, and the second rotating plate will bring the first pulling plate to rotate. The first pulling plate is wound with a tension spring to elastically stretch the tension spring, and elasticity is generated by the elastic stretching of the tension spring. The elasticity is transferred to the second rotating plate by the tension spring, and then to the first rotating plate by the second rotating plate and the coaxial relationship, and then to the anti-bending rod by the first rotating plate, and then to the angle steel body to form a buffer. This buffering effect assists the buffering force generated by the reinforcing rod and the shock-absorbing spring to further enhance the vibration resistance of the angle steel body.

A reinforcing mechanism is provided in the L-shaped clamping cavity of the angle steel body 1, and the reinforcing mechanism includes a row of anti-bending rods 4 installed in the L-shaped clamping cavity along the length direction, and each anti-bending rod 4 corresponds to between the first waist circular hole 2 set on the left and the second waist circular hole 3 on the right. The anti-bending rod 4 is L-shaped, and one end of the anti-bending rod 4 is bent toward the left side of the angle steel body 1 and fixed with a first fastener 5 that is slidably fitted in the first waist circular hole 2, and the other end of the anti-bending rod 4 is bent toward the right side of the angle steel body 1 and fixed with a first fastener 5 that is slidably fitted in The second fastener 6 in the second waist round hole 3, the reinforcement mechanism also includes a reinforcement rod 7, the reinforcement rod 7 is fixed together on all the anti-bending rods 4, and a vibration reduction mechanism is also provided in the angle steel body 1, the vibration reduction mechanism includes a pressure seat 8 fixed on the bottom end of the reinforcement rod 7, the reinforcement mechanism also includes a reinforcement tube 9 fixed on the bottom end of the angle steel body 1, and a first reinforcement plate 10 is welded to the bottom end of the reinforcement tube 9, the vibration reduction mechanism includes a vibration reduction spring 11 fixed on the top surface of the first reinforcement plate 10, the bottom end of the reinforcement rod 7 enters the reinforcement tube 9 with the pressure seat 8, the bottom surface of the pressure seat 8 is elastically connected to the top surface of the vibration reduction spring 11, and the top end of the vibration reduction spring 11 provides elastic force to the pressure seat 8, and the pressure seat 8 pushes the reinforcement rod 7, so that the top end of the reinforcement rod 7 exceeds the top of the angle steel body 1.

[0028] The first fastener 5 is a sliding seat, and the first fastener 5 includes a first slide plate 51 and a second slide plate 52 . The first slide plate 51 slides on the outer surface of the left side of the angle steel body 1 , and the second slide plate 52 slides on the inner surface of the left side of the angle steel body 1 .

[0029] The second fastener 6 is a pulley, and the second fastener 6 includes a first rotating plate 61 and a second rotating plate 62 installed on the right end of the anti-bending rod 4 through a rotating shaft. The outer cylindrical surface of the first rotating plate 61 rolls on the inner surface of the left side of the angle steel body 1, and the second rotating plate 62 is coaxial with the first rotating plate 61 and rotates synchronously with the first rotating plate 61.

[0030] A second reinforcing plate 12 is welded to the top of the reinforcing tube 9 , and a plug hole 13 is provided on the second reinforcing plate 12 . The bottom end of the reinforcing rod 7 passes through the plug hole 13 and enters the reinforcing tube 9 . The diameter of the plug hole 13 is larger than the diameter of the reinforcing rod 7 .

[0031] The vibration damping mechanism also includes a first pull plate 63 welded on the outer circumferential surface of the second rotating plate 62, and a second pull plate 64 welded on the outer side of the right side edge of the angle steel body 1. The vibration damping mechanism also includes a tension spring 65 connected between the first pull plate 63 and the second pull plate 64. The tension spring 65 is bent and bent on the outer periphery of the second pull plate 64.

[0032] When in use, the bottom end of the angle steel body 1 is welded to the steel structure, and the top end of the angle steel body 1 is welded to the steel structure. Affected by the welding of the top end of the angle steel body 1 and the steel structure, the top end of the reinforcing rod 7 is pressed against the steel structure. Affected by the steel structure, an extrusion effect is formed on the top end of the reinforcing rod 7, forcing the reinforcing rod 7 to descend, and the reinforcing rod 7 brings the pressure seat 8 down, and the pressure seat 8 pushes the shock-absorbing spring 11, so that the shock-absorbing spring 11 is compressed and shortened. When the steel structure provides a load to the top end of the angle steel body 1, the load not only acts on the top end of the angle steel body 1, but also acts on the top end of the reinforcing rod 7, and the top end of the reinforcing rod 7 acts on the entire reinforcing rod 7, and the entire reinforcing rod 7 acts on the pressure seat 8, and the pressure seat 8 acts on the shock-absorbing spring 11, and the shock-absorbing spring 11 acts on the first reinforcing plate 10, and the shock-absorbing spring 11 is compressed and shortened again, and at the same time generates elastic force, thereby forming a shock-absorbing effect on the load.

[0033] A row of anti-bending rods 4 are arranged from top to bottom in the L-shaped cavity of the angle steel body 1, and the two ends of the anti-bending rods 4 are bent to the left and right sides of the angle steel body 1, which is equivalent to forming two supports in the width direction in the clamping cavity of the angle steel body 1. The two ends of the anti-bending rods 4 are used to provide supporting force to the left and right sides of the angle steel body 1, thereby preventing the angle steel body 1 from bending in the width direction, and also used to resist the shear force of the angle steel body 1 in the width direction, further improving the bending strength of the angle steel body.

[0034] When the reinforcing rod 7 descends and uses the damping spring 11 to produce a downward buffering effect, it will also move all the anti-bending rods 4 downward. These anti-bending rods 4 will descend with the first fastener 5 and the second fastener 6. The first fastener 5 on the left side is used to descend along the first waist circular hole 2 on the left side to achieve stability on the left side. The second fastener 6 on the right side is used to descend along the second waist circular hole 3 on the right side to achieve stability on the right side. The first fastener 5 will not rotate when it descends, and when the second fastener 6 descends, the first rotating plate 61 will use its outer cylindrical surface to roll over the inner surface of the left side edge of the angle steel body 1 and move. The first rotating plate 61 will rotate, and the first rotating plate 61 will rotate. The plate 61 rotates with the second rotating plate 62 through a coaxial relationship, and the second rotating plate 62 rotates with the first pulling plate 63, and the first pulling plate 63 winds the tension spring 65, so that the tension spring 65 is elastically stretched, and the elastic stretching of the tension spring 65 generates elasticity, which is transferred from the tension spring 65 to the second rotating plate 62, and then to the first rotating plate 61 through the second rotating plate 62 and the coaxial relationship, and then to the anti-bending rod 4 through the first rotating plate 61, and then to the angle steel body 1 to form a buffer. The buffering effect assists the buffering force generated by the reinforcing rod 7 and the shock-absorbing spring 11, so that the vibration resistance of the angle steel body 1 is further enhanced.

[0035] like Figure 2 As shown, all the anti-bending rods 4 are distributed at equal distances along the length direction of the angle steel body 1. The anti-bending rods 4 are used to form a plurality of support bodies on the angle steel body 1, thereby further improving the anti-bending strength of the angle steel body 1.

[0036] like Figure 1 As shown, a reinforcement space 16 is formed between the reinforcement rod 7 and the inner surfaces of the left and right sides of the angle steel body 1. The reinforcement space 16 forms an anti-deformation distance between the reinforcement rod 7 and the angle steel body 1, further improving the bending strength of the angle steel body 1.

[0037] like Figure 2 , Figure 4 As shown, the first fastener 5 is offset above the second fastener 6, that is, the same anti-bending rod 4 utilizes two reinforcement points in different orientations to form upper and lower strength supports on the left and right sides of the angle steel body 1, further improving the anti-bending strength of the angle steel body 1.

[0038] like Figure 2 , Figure 4 As shown, the reinforcing tube 9 is a triangular tube, the first reinforcing plate 10 and the second reinforcing plate 12 are triangular plates, and the two triangular sides of the reinforcing tube 9 are welded to the left and right sides of the angle steel body 1, providing support force from the inside to the left and right sides of the angle steel body 1, assisting the anti-bending rod 4 in providing anti-deformation ability to the angle steel body 1, and the first reinforcing plate 10 and the second reinforcing plate 12 provide structural strength to the upper and lower ends of the reinforcing tube 9, so that the anti-deformation ability provided by the reinforcing tube 9 to the angle steel body 1 is further improved, and the setting of the reinforcing tube 9 is also used to install the damping spring 11, using the first reinforcing plate 10 as the bottom support of the damping spring 11, and using the plug hole 13 opened by the second reinforcing plate 12 to form an insertion structure to the bottom end of the reinforcing rod 7, to ensure that the reinforcing rod 7 is lifted and lowered smoothly. The purpose of using the triangular tube for the reinforcing tube 9 is that its outer side is flush with the angle steel body 1, and when it is welded in the steel structure, it prevents collision and reduces the installation space.

[0039] like Figures 2 to 6 As shown, the anti-bending rod 4 is provided with an assembly hole 14 which passes through from top to bottom, and the assembly holes 14 on all the anti-bending rods 4 coincide with each other on the same straight line. The reinforcing rod 7 passes through the assembly holes 14 on all the anti-bending rods 4. A thread is formed on the outer circumferential surface of the reinforcing rod 7. A plurality of nuts 15 are connected to the reinforcing rod 7 through threads, and the upper and lower ends of each anti-bending rod 4 are fixed to the reinforcing rod 7 by two nuts 15, that is, the anti-bending rod 4 is fixed to the reinforcing rod 7 by locking the double-end nuts 15, that is, the anti-bending rod 4 is installed on the reinforcing rod 7 in a detachable manner, and each component is convenient for separate processing and assembly.

[0040] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field.
