Description

Technical Field

[0001] This utility model relates to the field of factory building components, specifically to a retractable wind-resistant support rod for steel structure factory buildings. Background Technology

[0002] Steel structure factory buildings are a type of building that uses steel as the main load-bearing component. They are typically composed of load-bearing components such as steel columns, steel beams, steel roof trusses, and steel roofs. They can be widely used in industrial, logistics, agricultural, and public building fields. Common steel structure factory buildings use telescopic support rods to overcome the limitations of traditional rigid supports in terms of factory building deformation.

[0003] Currently, the telescopic support rods used in steel structure workshops use thick-walled round steel pipes as the main load-bearing components, and are then combined with inner core rods and ear plates to connect with steel roof trusses, steel roofs and other components. Spring buffers are installed between the thick-walled round steel pipes and the inner core rods, and friction components are used to provide wind resistance and support.

[0004] However, the spring buffer components of the telescopic support rods commonly used in steel structure workshops are prone to damage during long-term elastic vibration in actual use. Since the spring buffer components are located inside the telescopic tube, disassembly and replacement are inconvenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a retractable wind-resistant support rod for steel structure workshops, which improves the efficiency of replacing elastic spring components during maintenance and reduces the hassle of disassembly.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: a telescopic wind-resistant support rod for steel structure workshops, including an outer sleeve, an inner core rod, and an ear plate. The upper end of the outer sleeve is threadedly connected to a connecting sleeve. A slip ring is in contact with the connecting sleeve. Receiving grooves are opened on both sides of the slip ring that are far apart from each other. An adjusting rod is threadedly connected to the slip ring at the receiving groove. The adjusting rod is inserted into the outer wall of the inner core rod. A rubber pad ring is in contact with the connecting sleeve. A retaining sleeve is glued to the opposite side of the two rubber pad rings. A first spring body is in contact between the two retaining sleeves. A protruding plate is fixedly connected to the far end of the two adjusting rods. A first through hole is opened on the side of the protruding plate near the connecting sleeve. A first spring push rod is inserted into the first through hole. An adaptation hole is inserted into the end of the first spring push rod. The adaptation hole is located on the connecting sleeve and on the upper and lower sides of the slip ring.

[0007] As a preferred technical solution of this utility model, the four mutually spaced sides of the ferrule are rotatably embedded with support balls, which are in contact with the inner wall of the connecting cylinder. By setting the support balls, the friction of the ferrule movement is reduced.

[0008] As a preferred technical solution of this utility model, a dustproof tube is sleeved on the connecting tube, the bottom side of the dustproof tube is in contact with the outer tube, and a second through hole is opened on the side of the outer tube near the ear plate. A second spring rod is inserted into the second through hole, and the end of the second spring rod is inserted into the dustproof tube. By setting the second spring rod, the dustproof tube can be limited and can be easily disassembled.

[0009] As a preferred technical solution of this utility model, a telescopic rod is provided inside the connecting cylinder. The telescopic rod is fixedly connected to the outer sleeve and movably inserted into the inner core rod. By providing the telescopic rod, compression buffer can be provided.

[0010] As a preferred technical solution of this utility model, the upper end of the connecting cylinder is fixedly connected with protrusions on all four sides. The connecting cylinder has an annular groove on the side away from the protrusions and is filled with packing material. By setting the protrusions and packing material, the sealing effect between the inner core rod and the connecting cylinder can be increased. At the same time, when rotating the connecting cylinder, the protrusions can be rotated first.

[0011] This utility model has the following advantages: by setting a connecting cylinder between the outer sleeve and the inner core rod, and setting a slip ring inside the connecting cylinder, and then setting buffer structures on both the upper and lower sides of the slip ring, and cooperating with the adaptation hole and the first spring push rod, it can provide a small buffer and provide the spring contraction threshold. Moreover, when disassembling and replacing the elastic component, it is only necessary to rotate the protrusion to move the connecting cylinder upward, and then disassemble it from the bottom side of the connecting cylinder, thus improving maintenance efficiency.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The diagram shows a retractable wind-resistant support rod for steel structure workshops, comprising an outer sleeve 1, an inner core rod 2, and ear plates 3. A connecting sleeve 4 is threaded to the upper end of the outer sleeve 1. A slip ring 5 is in contact with the connecting sleeve 4. Receiving grooves 6 are provided on both opposite sides of the slip ring 5, allowing a protruding plate on one side of an adjusting rod 7 to be accommodated. The adjusting rod 7 is threaded to the slip ring 5 at the receiving groove 6. Rotating the adjusting rod 7 allows the slip ring 5 to slide relative to the inner core rod 2. The adjusting rod 7 is inserted into the outer wall of the inner core rod 2. A rubber washer 8 is in contact with the connecting sleeve 4. The rubber washer 8, in conjunction with a retaining sleeve 9, provides energy release at the first spring body 10. Retaining sleeves 9 are glued to the opposite sides of both rubber washer 8. The sleeve 9 cooperates with the first spring body 10, and the two first spring bodies 10 are located on the upper and lower sides of the slip ring 5, which can provide upper and lower buffering for the inner core rod 2. The two sleeves 9 are in contact with the first spring body 10. The two adjusting rods 7 are fixedly connected to the opposite ends of the two sleeves. The protruding plate has a first through hole on the side of the protruding plate near the connecting cylinder 4. The first spring push rod 17 is inserted into the first through hole. The end of the first spring push rod 17 is inserted into the adaptation hole 18. The adaptation hole 18 is located on the connecting cylinder 4 and on the upper and lower sides of the slip ring 5. When the first spring push rod 17 is inserted into the adaptation hole 18, the maximum threshold for the extension and contraction of the first spring body 10 is formed, which can reduce relative sliding and achieve locking.

[0018] Among them, the four mutually spaced sides of the ferrule 9 are rotatably embedded with support balls 11, which are in contact with the inner wall of the connecting cylinder 4. By setting the support balls 11, the friction of the ferrule 9 can be reduced, making it easier to disassemble.

[0019] The connecting cylinder 4 is fitted with a dustproof cylinder 12. The bottom side of the dustproof cylinder 12 contacts the outer sleeve 1. The outer sleeve 1 has a second through hole on the side near the ear plate 3. A second spring rod 13 is inserted into the second through hole. The end of the second spring rod 13 is inserted into the dustproof cylinder 12. By setting the dustproof cylinder 12 in conjunction with the second spring rod 13, the gap between the connecting cylinder 4 and the outer sleeve 1 can be blocked.

[0020] The connecting cylinder 4 is equipped with a telescopic rod 14, which is fixedly connected to the outer sleeve 1 and movably inserted into the inner core rod 2. By setting the telescopic rod 14, the adaptability of the inner core rod 2 can be improved when the bottom first spring body 10 is contracted. The telescopic rod 14 can be fully extended and retracted into the inner core rod 2.

[0021] The upper end of the connecting cylinder 4 is fixedly connected with protrusions 15 on all four sides. The connecting cylinder 4 has an annular groove on the side away from the protrusions 15 and a filler 16 is provided in the annular groove. By providing the filler 16, a sealing effect can be provided at the gap between the inner core rod 2 and the connecting cylinder 4. At the same time, by providing the protrusions 15, it is easy to rotate the connecting cylinder 4 when it is necessary to disassemble and maintain the elastic component.

[0022] Working principle: When the ear plate 3 is connected to the steel roof truss and steel cover plate, the first spring body 10 provides the extension and contraction buffer of the inner core rod 2. At the same time, the first spring top rod 17 provides the extension and contraction threshold and increases the self-locking structure. The sleeve 9 and the rubber pad ring 8 provide collision energy release. When maintenance of the elastic component is required, the dust cover 12 can be moved upward by manually pressing the second spring top rod 13. Then, the protrusion 15 is rotated to move the connecting cylinder 4 upward until it is separated from the outer sleeve 1. At this time, the inner core rod 2 and the connecting cylinder 4 move relative to each other, and the receiving groove 6 is exposed. At this time, the adjusting rod 7 and the protrusion can be removed, and then both first spring bodies 10 can be removed, which can improve the efficiency of disassembly and replacement.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
