Description

Technical Field

[0001] This invention relates to the technical field of fastening structures, and in particular to a convenient fastening device for ventilation pipes of angle steel towers. Background Technology

[0002] In modern communication network infrastructure, angle steel towers serve as the core supporting structure for base station equipment. Their stability and reliability are directly related to the quality and coverage of the communication network. With the rapid development of mobile communication technology, 5G and future communication systems have placed higher demands on the power output of base station equipment. This has led to a significant increase in the heat generated by the internal components of the base station. Efficient heat dissipation has become one of the key factors to ensure the long-term stable operation of the base station.

[0003] Base station heat dissipation generally relies on fans and ventilation ducts to remove heat. The ventilation ducts are mainly installed on angle steel towers. The traditional installation method is to use bolts, lock nuts, clamps and other structural methods to fix the ventilation ducts. However, this fixing method is mainly for the straight part of the ventilation duct. It cannot effectively fix the ventilation duct at the bend, which results in poor fixing effect of the ventilation duct. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a convenient fastening device for ventilation pipes of angle steel towers, the specific technical solution of which is as follows: A convenient angle steel tower ventilation pipe fastening device includes a first connector for quick connection with angle steel and a second connector for quick fixation of the ventilation pipe, wherein the first connector is connected to the second connector. The second connector includes a storage box and a cover. The storage box is square in shape, and the cover is fitted onto the opening of the storage box. The storage box is hollow inside, and storage openings are provided on two adjacent outer walls of the storage box. The storage openings are used for ventilation pipes to pass through. The opening direction of the storage openings is the same as the opening direction of the storage box, and the two openings intersect.

[0005] Furthermore, a slot is provided on the inner wall of the opening of the storage box, and an insertion frame is provided on the cover plate. One-way teeth that cooperate with each other are provided in both the slot and the insertion frame. The first connector has a notch on one side wall that communicates with the slot. The cross-section of the insert frame is right-angled. When the storage box and the cover are assembled, the cover and the opening of the storage box are on the same vertical plane. The cover is moved laterally and the insert frame on the cover is inserted into the slot.

[0006] Furthermore, a rubber ring is provided on the cover plate.

[0007] Furthermore, each storage opening on the storage box is equipped with a support plate, which is fixed to the cover plate. A top pressure plate is slidably mounted on the support plate. The top pressure plate is used to press against the vertical side wall of the ventilation pipe inside the storage box. The support plate and the top pressure plate are connected by a leaf spring.

[0008] Furthermore, the storage box is provided with an extrusion body for extruding the ventilation pipe; The extrusion body includes an inclined sleeve, with extrusion plates extending outward from both ends of the sleeve. The two extrusion plates slide on the inner wall of the storage box where the two storage openings are located. The inclined sleeve and the storage box are connected by a spring. The extrusion plate has a beveled edge on its side wall facing the opening of the storage box.

[0009] Furthermore, the storage box is rotatably equipped with a turntable, the axis of which is perpendicular to the inclined sleeve. A threaded rod is provided on the turntable, which passes through the turntable and is threadedly connected. A guide sleeve is fitted on the outer side of the threaded rod, which is fixed on the inclined sleeve. A retaining sleeve is slidably fitted on the outer side of the guide sleeve, and a spring connects the inclined sleeve and the retaining sleeve. The guide sleeve, clamp, and turntable are all polygonal.

[0010] Furthermore, the first connecting body includes a connecting plate and a right-angled groove formed on the connecting plate, the right-angled groove being used to be fitted onto an angle steel; The right-angle groove consists of a right-angle plate and a top plate rotatably mounted on top of the connecting plate.

[0011] Furthermore, a slot is provided on the top of the connecting plate, and a fixing groove is provided on the bottom surface of the top plate. A rubber protrusion is provided in the fixing groove. When the rubber protrusion moves into the slot, the rubber protrusion limits the position of the top plate.

[0012] The advantages of this invention are: By employing a second connector consisting of a storage box and a cover plate, the bends in the ventilation duct can be directly wrapped and secured, thus connecting the ventilation duct to the angle steel tower. This effectively improves the fixing effect of the ventilation duct, enhances installation convenience, and significantly simplifies the installation process. It eliminates the need for complex tools or lengthy operations, improving on-site construction efficiency and reducing labor costs. When maintenance or adjustment of the ventilation duct is required, simply opening the cover plate allows for easy access, facilitating daily inspection and maintenance and extending the maintenance cycle and service life of the entire communication base station facility. In summary, this convenient angle steel tower ventilation duct fastening device, through its innovative design, not only effectively solves the fixing problems in existing technologies but also greatly improves the convenience of installation and maintenance, enhancing the stability and economy of the communication base station.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 9 As shown, a convenient angle steel tower ventilation pipe fastening device of the present invention includes a first connecting body 1 for quick connection with angle steel 3 and a second connecting body 2 for quick fixation of ventilation pipe 4, wherein the first connecting body 1 and the second connecting body 2 are connected. The second connecting body 2 includes a storage box 5 and a cover plate 6. The storage box 5 is square in shape, and the cover plate 6 is installed on the opening of the storage box 5. The storage box 5 is hollow inside, and storage openings are provided on two adjacent outer walls of the storage box 5. The storage openings are used for the ventilation pipe 4 to pass through. The opening direction of the storage openings is the same as the opening direction of the storage box 5, and the two openings intersect.

[0019] In detail, since the two storage openings on the storage box 5 are located on two adjacent outer walls of the storage box 5, the directions of the two storage openings are at an angle, and this angle is the same as the angle of the corner position of the ventilation pipe 4. In actual use, this angle is generally a right angle. The angle steel 3 is a position on the angle steel tower. The first connecting body 1 and the second connecting body 2 are welded together. The first connecting body 1 is used to connect the angle steel 3, and the second connecting body 2 is used to fix the corner position of the ventilation pipe 4. In this way, the corner position of the ventilation pipe 4 is fixed on the first connecting body 1, thereby achieving the purpose of quickly fixing the ventilation pipe 4 on the angle steel tower.

[0020] During operation, the first connector 1 is fixed to the angle steel 3, the cover plate 6 on the storage box 5 is opened, the corner of the ventilation pipe 4 is inserted into the storage box 5 through the opening of the storage box 5, and the two ends of the corner of the ventilation pipe 4 extend out of the storage box 5 through two storage ports respectively. Then the cover plate 6 is fixed to the opening of the storage box 5, so that the corner of the ventilation pipe 4 can be quickly clamped and fixed through the storage box 5 and the cover plate 6. This fixing method is simple, convenient to operate, and can be achieved without carrying other tools.

[0021] By employing a second connector 2 composed of a storage box 5 and a cover plate 6, the bends of the ventilation duct 4 can be directly wrapped and fixed, thereby connecting the ventilation duct 4 to the angle steel tower. This effectively improves the fixing effect of the ventilation duct 4, enhances installation convenience, and significantly simplifies the installation process. It eliminates the need for complex tools or lengthy operations, improving on-site construction efficiency and reducing labor costs. When maintenance or adjustment of the ventilation duct is required, simply opening the cover plate 6 allows for easy operation, facilitating daily inspection and maintenance, and extending the maintenance cycle and service life of the entire communication base station facility. In summary, this convenient angle steel tower ventilation duct fastening device, through its innovative design, not only effectively solves the fixing problems in existing technologies but also greatly improves the convenience of installation and maintenance, enhancing the stability and economy of the communication base station.

[0022] Furthermore, a slot 7 is provided on the inner wall of the opening of the storage box 5, and an insertion frame 8 is provided on the cover plate 6. Both the slot 7 and the insertion frame 8 are provided with one-way teeth that cooperate with each other. The first connecting body 1 has a notch on one side wall that communicates with the slot 7. The cross-section of the insert frame 8 is right-angled. When the storage box 5 and the cover plate 6 are assembled, the cover plate 6 and the opening of the storage box 5 are on the same vertical plane. The cover plate 6 is moved laterally, and the insert frame 8 on the cover plate 6 is inserted into the slot 7.

[0023] In detail, slots 7 are provided on the upper and lower sides and the left side of the inner wall of the opening of the storage box 5, and the right side wall of the storage box 5 is notched near the opening. This allows the insert frame 8 to be inserted horizontally into the slot 7. During assembly, the side wall of the cover plate 6 is on the same vertical plane as the opening of the storage box 5. The cover plate 6 moves horizontally, which moves the insert frame 8 on it horizontally. The insert frame 8 is inserted into the slot 7. After the cover plate 6 has sealed the opening of the storage box 5, the cover plate 6 moves a small distance away from the storage box 5. At this time, the one-way teeth on the insert frame 8 and the one-way teeth in the slot 7 engage with each other, thereby fixing the position of the cover plate 6 on the storage box 5. This allows for a quick and secure connection between the storage box 5 and the cover plate 6.

[0024] Specifically, since the cross-section of the insert frame 8 is right-angled, the vertical part of the insert frame 8 is inserted into the slot 7, and the horizontal part of the insert frame 8 is used to install on the cover plate 6.

[0025] Furthermore, a rubber ring 9 is provided on the cover plate 6.

[0026] In detail, the rubber ring 9 is fitted onto the horizontal part of the insert frame 8 and is connected to the cover plate 6. When the cover plate 6 is installed, since the opening of the cover plate 6 and the storage box 5 are on the same vertical plane, the rubber ring 9 is in a compressed state. After the cover plate 6 is assembled, the worker releases the force on the cover plate 6, and the rubber ring 9 returns to its initial state. At this time, the rubber ring 9 pushes the cover plate 6 away from the storage box 5 by a small distance, thereby engaging the one-way teeth on the insert frame 8 with the one-way teeth in the slot 7. Thus, the rubber ring 9 keeps the slot 7 and the one-way teeth on the insert frame 8 in a meshing state, and the rubber ring 9 fills the gap between the cover plate 6 and the storage box 5.

[0027] Furthermore, each storage opening on the storage box 5 is equipped with a support plate 10, which is fixed to the cover plate 6. A top pressure plate 11 is slidably mounted on the support plate 10. The top pressure plate 11 is used to press the vertical side wall of the ventilation pipe 4 inside the storage box 5. The support plate 10 and the top pressure plate 11 are connected by a leaf spring 12.

[0028] In detail, due to the notch on the storage box 5, the support plate 10, the top pressure plate 11 and the leaf spring 12 on the cover plate 6 can move smoothly with the cover plate 6. The leaf spring 12 provides elastic thrust to the top pressure plate 11, thereby providing extrusion force to the vertical side wall of the ventilation pipe 4, which makes it easy to firmly install the ventilation pipe 4 on the second connector 2. Furthermore, this structure can compress and fix ventilation pipes 4 with different longitudinal depths, thus improving the applicability of the second connector 2.

[0029] Furthermore, the storage box 5 is provided with an extrusion body 13 for extruding the ventilation pipe 4; The extrusion body 13 includes an inclined sleeve 14, with extrusion plates 15 extending outward from both ends of the inclined sleeve 14. The two extrusion plates 15 slide on the inner wall of the storage box 5 where the two storage openings are located, and the inclined sleeve 14 is connected to the storage box 5 by a spring 16. The extrusion plate 15 has a beveled edge 21 on its side wall facing the opening of the storage box 5.

[0030] In detail, the width of the storage opening on the storage box 5 is larger than the size of the ventilation tube 4. With the help of the spring 16, the thrust generated by the inclined sleeve 14 provides a pushing force to the two extrusion plates 15. Since the extrusion plates 15 slide on the inner wall of the storage box 5 where the storage opening is located, the moving direction of the inclined sleeve 14 is relatively inclined to the moving direction of the extrusion plates 15. The extrusion plates 15 exert extrusion force on the surface of the ventilation tube 4, thereby fixing the ventilation tube 4 in the storage opening.

[0031] By using the top pressure plate 11 and the squeezing plate 15 together, the ventilation pipe 4 can be squeezed and fixed from two directions. This allows ventilation pipes 4 of different diameters to be placed and fixed in the storage opening. The inclined side 21 allows the ventilation pipe 4 to push the squeezing plate 15 to move when it enters the storage opening, so that the ventilation pipe 4 can be smoothly installed into the storage opening.

[0032] Furthermore, the storage box 5 is rotatably provided with a turntable 17, the axis of the turntable 17 is perpendicular to the inclined sleeve 14, the turntable 17 is provided with a threaded rod 18, the threaded rod 18 passes through the turntable 17 and is threadedly connected, the outer side of the threaded rod 18 is provided with a guide sleeve 19, the guide sleeve 19 is fixed on the inclined sleeve 14, the outer side of the guide sleeve 19 is slidably provided with a retaining sleeve 20, and the spring 16 connects the inclined sleeve 14 and the retaining sleeve 20; Among them, the guide sleeve 19, the ferrule 20 and the turntable 17 are all polygonal.

[0033] In detail, the guide sleeve 19 can guide the ferrule 20. When the ferrule 20 is slidably sleeved on the turntable 17, due to the shape constraints of the turntable 17 and the ferrule 20, the ferrule 20 plays a locking role on the turntable 17 and provides support for the spring 16.

[0034] During use, the worker can move the sleeve 20 to disengage from the turntable 17. At this time, the spring 16 is in an elastic deformation state. The spring 16 exerts a force on the inclined sleeve 14, and the movement of the inclined sleeve 14 can drive the threaded rod 18 to rotate. The threaded rod 18 drives the turntable 17 to rotate. When the extrusion plate 15 extrudes and fixes the ventilation pipe 4, the sleeve 20 is released, and the spring 16 pushes the sleeve 20 to be fitted onto the outside of the turntable 17. At this time, the sleeve 20 plays a locking role on the turntable 17, so that the threaded rod 18, the inclined sleeve 14 and the extrusion plate 15 are all in a locked state, improving the fixing effect of the ventilation pipe 4 and preventing loosening.

[0035] Furthermore, the first connecting body 1 includes a connecting plate 22 and a right-angled groove formed on the connecting plate 22, the right-angled groove being used to be fitted onto the angle steel 3; The right-angle groove consists of a right-angle plate 23 and a top plate 24 rotatably mounted on the top of the connecting plate 22.

[0036] In detail, one end of the connecting plate 22 is connected to the second connecting body 2, and the other end of the connecting plate 22 has a right-angle groove. The right-angle groove is composed of a right-angle plate 23 and a top plate 24. The right-angle plate 23 is right-angled. The vertical side of the right-angle plate 23 and the connecting plate 22 form the vertical part of the right-angle groove, and the bottom of the vertical part is sealed. The horizontal side of the right-angle plate 23 and the top plate 24 form the horizontal part of the right-angle groove. When the first connecting body 1 is connected to the angle steel 3, the top plate 24 is rotated so that the top plate 24 deviates from the right-angle plate 23. The connecting plate 22 is moved from bottom to top towards the angle steel 3. The vertical part of the right-angle groove between the right-angle plate 23 and the connecting plate 22 is stuck on the vertical side of the angle steel 3. The horizontal right-angle side of the right-angle plate 23 is against the bottom of the horizontal right-angle side of the angle steel 3. The top plate 24 is rotated so that the top plate 24 is rotated to the top of the angle steel 3. Thus, the angle steel 3 is quickly connected and fixed through the right-angle plate 23 and the top plate 24.

[0037] Furthermore, a slot is provided on the top of the connecting plate 22, and a fixing groove is provided on the bottom surface of the top plate 24. A rubber protrusion 25 is provided in the fixing groove. When the rubber protrusion 25 moves into the slot, the rubber protrusion 25 limits the position of the top plate 24.

[0038] In detail, to prevent the top plate 24 from rotating arbitrarily and causing the connecting plate 22 to separate from the angle steel 3, the position of the top plate 24 can be limited by the setting of the slot and the rubber protrusion 25. When the top plate 24 rotates, the inner wall of the slot pushes the rubber protrusion 25 to deform and move out of the slot. At this time, the top plate 24 can rotate on the connecting plate 22.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
