Description

Technical Field

[0001] This utility model relates to the field of lightning protection equipment technology, and specifically to a prefabricated building lightning protection bracket. Background Technology

[0002] With the continuous advancement of the modern construction industry, prefabricated buildings have been widely used due to their significant advantages such as fast construction speed and environmental protection and energy saving. However, the installation of lightning protection facilities in prefabricated buildings still faces many challenges. As a key device to protect buildings from lightning strikes, lightning rods are usually installed on the roof of buildings, but the installation difficulty of lightning rods increases significantly in prefabricated buildings with sloping roofs.

[0003] Existing lightning rod mounting brackets are poorly adaptable to sloping roofs, lacking the necessary flexibility and unable to adjust the angle according to the specific shape of the roof. This not only makes the installation process complex and time-consuming, but also increases the labor intensity of workers and construction costs, affecting the overall project efficiency and safety. Summary of the Invention

[0004] The technical problem to be solved by this utility model is how to improve the flexibility and adaptability of lightning protection brackets, so that the angle of the lightning protection brackets can be adjusted according to different roof shapes.

[0005] The technical solution adopted by this utility model is: a prefabricated building lightning protection bracket, including a bracket base installed on the roof of a prefabricated building, and an installation plate installed in the bracket base. A rotating seat is provided on the top surface of the installation plate, and a sleeve is rotatably connected to the rotating seat. A boss is provided at one end of the sleeve near the rotating seat. The boss and the rotating seat are connected by a rotating shaft. An adjusting shaft for adjusting the position of the sleeve is installed at one end of the rotating seat away from the rotating shaft.

[0006] The above structure has the following beneficial effects:

[0007] (1) Since the sleeve and the rotating seat are connected by rotation and the position is adjusted by the boss and the adjusting shaft, the angle of the lightning rod can be flexibly adjusted according to the specific slope of the roof of the prefabricated building. It can easily adapt to both flat and sloping roof buildings and can effectively solve the problem of difficult installation of lightning rods under different building forms.

[0008] (2) Through standardized basic components and adjustable design, the angle of the lightning rod can be adjusted according to actual needs, expanding the applicable scenarios of prefabricated building lightning protection brackets.

[0009] Preferably, the adjusting shaft is inserted into the boss and is on the same axis as the rotating shaft. The adjusting shaft is provided with a rotating boss, and the boss is provided with a rotating groove. The rotating boss and the rotating groove cooperate with each other.

[0010] By inserting the adjusting shaft into the boss and setting it coaxially with the rotating shaft, the stability of the sleeve is ensured during adjustment. The rotating boss on the adjusting shaft cooperates with the rotating groove inside the boss to realize the rotational connection between the adjusting shaft and the sleeve, so that the sleeve can also make timely feedback when the adjusting shaft is rotated and move with the adjusting shaft.

[0011] Preferably, the rotating seat has a first gear tooth on one side, and the boss has a second gear tooth on the side near the first gear tooth, and the first gear tooth and the second gear tooth mesh with each other.

[0012] By setting a first gear on one side of the rotating seat and a second gear on one side of the boss, and making the first gear and the second gear mesh, a mechanical self-locking function can be achieved after the sleeve has completed the angle adjustment. This effectively prevents the sleeve from shifting or loosening during use, and improves the overall stability and safety of the lightning arrester bracket.

[0013] Preferably, a handwheel is connected to the end of the adjusting shaft away from the boss.

[0014] A handwheel is connected to the end of the adjusting shaft away from the boss, which facilitates manual adjustment by the operator. The position of the sleeve can be moved by turning the handwheel, and then the sleeve angle can be adjusted according to actual needs. Finally, the position of the sleeve can be fixed by adjusting the handwheel again.

[0015] Preferably, a limiting plate is provided on one side of the bracket base, and the limiting plate is connected to the bracket base via a first locking knob.

[0016] A limiting plate is installed on one side of the bracket base and fixedly connected by the first locking knob. This can further limit and fix the mounting plate after it is installed, preventing the mounting plate from falling off due to external vibration or wind, and further enhancing the stability of the prefabricated building lightning protection bracket.

[0017] Preferably, the mounting plate has multiple sliding cavities on both sides, each sliding cavity is slidably connected to a slider, and multiple slots are provided at corresponding positions on the bracket base. A fixing rod is also provided inside the sliding cavity, the slider is sleeved on the fixing rod, and an elastic element is provided on the fixing rod. One end of the elastic element abuts against the inner wall of the sliding cavity, and the other end abuts against the slider.

[0018] Sliding cavities are provided on both sides of the mounting plate, and automatic alignment and locking with the bracket base slots are achieved through the cooperation of sliders, fixing rods and elastic elements. This effectively simplifies the installation steps and improves installation efficiency. The design of the elastic elements enables the slider to have an automatic reset function, further enhancing the convenience of the installation process.

[0019] Preferably, the mounting plate is provided with an "L"-shaped limiting groove, which includes a first sliding groove 3041 and a second sliding groove 3042. The slider is rotatably connected to an "L"-shaped limiting rod, and the end of the "L"-shaped limiting rod away from the slider passes through the "L"-shaped limiting groove and is slidably connected with the first sliding groove 3041 and the second sliding groove 3042.

[0020] By setting an "L"-shaped limiting groove on the mounting plate and an "L"-shaped limiting rod on the slider, and cooperating the "L"-shaped limiting rod with the "L"-shaped limiting groove, the operator can control the extension and retraction of the slider by sliding and rotating. This allows the slider to be retracted into the sliding cavity before installation. After the mounting plate is placed in the bracket base, the "L"-shaped limiting rod is moved, and then the slider slides into the slot on the bracket base under the action of the elastic element.

[0021] Preferably, the sleeve is provided with a second locking knob and a third locking knob for clamping the lightning rod body.

[0022] By setting a second and a third locking knob on the sleeve, a double clamping structure is formed, which can effectively enhance the clamping and fixing effect of the lightning rod body and ensure that the lightning rod body can remain stable in various environments.

[0023] Preferably, the second locking knob includes an arc-shaped plate and an adjusting knob, the adjusting knob being threadedly connected to the sleeve and rotatably connected to the arc-shaped plate, the arc-shaped plate being located inside the sleeve.

[0024] The second locking knob adopts a combination structure of arc plate and adjustment knob, and realizes precise adjustment of clamping force through thread drive, which can adapt to lightning rod bodies of different diameters, and improves the applicability and installation compatibility of lightning rod bracket.

[0025] Preferably, the third locking knob is installed at the top of the sleeve and is threadedly connected to the sleeve, and the top of the sleeve has a wedge-shaped structure inside.

[0026] The top of the third locking knob is designed with a wedge-shaped structure. When tightened, the wedge-shaped clamping action helps to fix the lightning rod body, forming a multi-point clamping structure. This further enhances the stability of the lightning rod installation and prevents it from loosening or falling off due to external forces. Attached Figure Description

[0040] Example

[0041] The following description, in conjunction with specific embodiments, provides further details. Figure 1-9 As shown, this embodiment is a lightning protection bracket for prefabricated buildings, including a bracket base 1, a limiting plate 2, and an mounting plate 3. The bracket base 1 is installed on the roof of the prefabricated building, and the mounting plate 3 is installed inside the bracket base 1. The limiting plate 2 limits the position of the mounting plate 3. The limiting plate 2 and the bracket base 1 are connected and fixed by a first locking knob 201. When the mounting plate 3 is fully installed inside the bracket base 1, the limiting plate 2 prevents the mounting plate 3 from shifting or falling off. To improve the installation efficiency of workers on the construction site, the mounting plate 3 has... The mounting plate 3 is provided with multiple sliding cavities 301, each containing a slider 4. Multiple slots are provided at corresponding positions on the support base 1. A fixing rod 302 is provided inside the sliding cavity 301, and the slider 4 is fitted onto the fixing rod 302. An elastic element 303, which is a spring, is also provided on the fixing rod 302. One end of the elastic element 303 abuts against the inner wall of the sliding cavity 301, and the other end abuts against the slider 4. Under the action of the elastic element 303, the slider 4 can automatically move towards the slots on the support base 1, thereby achieving rapid fixation of the mounting plate 3.

[0042] An "L"-shaped limiting groove 304 is also provided on the mounting plate 3. The "L"-shaped limiting groove 304 includes a first sliding groove 3041 and a second sliding groove 3042. One end of the slider 4, which is slidably connected to the mounting plate 3, is provided with an "L"-shaped limiting rod 401. The "L"-shaped limiting rod 401 and the slider 4 are rotatably connected. The end of the "L"-shaped limiting rod 401 away from the slider 4 passes through the first sliding groove 3041 and can slide along the first sliding groove 3041. When installing the mounting plate 3, the "L"-shaped limiting rod 401 can be first moved along the first sliding groove 3041. The first slide groove 3041 slides, and after reaching the position of the second slide groove 3042, the "L"-shaped limiting rod 401 is rotated so that one end of the "L"-shaped limiting rod 401 slides into the second slide groove 3042, thereby causing the slider 4 connected to the "L"-shaped limiting rod 401 to retract into the sliding cavity 301, so that the mounting plate 3 can be smoothly installed into the bracket base 1 during installation. Then, the "L"-shaped limiting rod 401 is moved so that the slider 4 slides into the slot provided on the bracket base 1 under the action of the elastic element 303.

[0043] A rotating seat 5 is provided on the top of the mounting plate 3, and a sleeve 6 is rotatably connected to the rotating seat 5. A boss 601 is provided at one end of the sleeve 6 near the rotating seat 5. The boss 601 and the rotating seat 5 are connected by a rotating shaft 7 and an adjusting shaft 8. The rotating shaft 7 and the adjusting shaft 8 are respectively installed on both sides of the boss 601. The rotating shaft 7 is fixedly connected to the rotating seat 5, while it is rotatably connected to the boss 601. A first gear tooth 501 is provided on one side of the rotating seat 5, and a second gear tooth 602 is provided on the side of the boss 601 near the first gear tooth 501. Adjustment is achieved through the rotating groove on the boss 601 and the rotating boss on the adjusting shaft 8. In addition to the rotatable connection between the adjusting shaft 8 and the boss 601, a handwheel 801 is also provided at the end of the adjusting shaft 8 away from the boss 601. When the handwheel 801 is turned, the adjusting shaft 8 will also rotate, thereby changing the position of the adjusting shaft 8. The position of the boss 601 connected to the adjusting shaft 8 will also change, which in turn will cause the position of the sleeve 6 to change. Then the angle of the sleeve 6 can be adjusted. After the angle is adjusted, the handwheel 801 is turned so that the boss 601 is close to the rotating shaft 7, realizing the meshing of the gear teeth 501 and completing the fixation of the angle of the sleeve 6.

[0044] A second locking knob 802 and a third locking knob 9 are provided on the sleeve 6 for clamping and fixing the lightning rod body. The second locking knob 802 is located in the middle of the sleeve 6 and includes an arc-shaped plate 8021 and an adjusting knob 8022. The adjusting knob 8022 is threadedly connected to the sleeve 6, and the arc-shaped plate 8021 is rotatably connected to the adjusting knob 8022. The arc-shaped plate 8021 is located inside the sleeve 6. By rotating the adjusting knob 8022, the arc-shaped plate 8021 can be moved, thereby clamping or releasing the lightning rod body. The third locking knob 9 is located at the top of the sleeve 6 and is threadedly connected to the sleeve 6. The top of the third locking knob 9 has a wedge-shaped structure inside. When the third locking knob 9 is tightened, the wedge-shaped structure of the third locking knob 9 will press the lightning rod body, thereby further enhancing the fixing effect and ensuring the stable installation of the lightning rod body.

[0045] Working principle:

[0046] When installing the mounting plate 3, first slide the "L"-shaped limiting rod 401, causing it to move along the first sliding groove 3041 until it reaches the position of the second sliding groove 3042. Then, rotate the "L"-shaped limiting rod 401, causing one end of it to slide into the second sliding groove 3042, thereby retracting the slider 4 connected to the "L"-shaped limiting rod 401 into the sliding cavity 301. Then, install the mounting plate 3 into the bracket base 1, and then rotate the "L"-shaped limiting rod 401 into the first sliding groove 3041. Under the action of the elastic element 303, the slider 4 slides into the slot provided on the bracket base 1, thus fixing the mounting plate 3. Since the roof of the prefabricated building may have a sloping roof, an angle-adjustable sleeve is provided on the top surface of the mounting plate 3. A gear tooth 501 is provided between the sleeve 6, the rotating seat 5, and the cylinder 6. When the angle of the sleeve 6 needs to be adjusted, the position of the adjusting shaft 8 connected to the handwheel 801 is moved by rotating the handwheel 801, which in turn causes the position of the sleeve 6, which is rotatably connected to the adjusting shaft 8, to also change. When the boss 601 on the sleeve 6 moves away from the rotating seat 5 with the gear tooth 501, the position of the sleeve 6 can be adjusted. After the sleeve 6 is adjusted to the appropriate position, the handwheel 801 is rotated again to move the sleeve 6, so that the gear tooth 501 on the boss 601 on the sleeve 6 meshes with the gear tooth 501 on the gear seat, thus fixing the angle of the sleeve 6. The lightning rod body can be effectively fixed by rotating the second locking knob 802 and the third locking knob 9 on the sleeve 6, ensuring the stable installation of the lightning rod body.
