Abstract
Description
Technical Field
[0001] This utility model relates to the field of security engineering wiring tools, specifically a fixing device for facilitating security engineering wiring. Background Technology
[0002] Secure cabling in security systems is a crucial step in ensuring stable system operation. The appropriate method must be selected based on the cable type (e.g., video cable, power cable, signal cable) and the installation environment (wall, ceiling, cable tray, etc.). Common fasteners include cable clips, cable ties, cable trays, and conduit clamps. Surface-mounted cabling often uses cable clips to secure the cabling at intervals, while concealed cabling requires the use of cable trays or conduits for secure installation.
[0003] In security engineering cabling installations, existing fixing devices have significant limitations in adaptability: their structures are mostly fixed designs, and the angle cannot be flexibly adjusted according to the actual laying scenario. In actual construction, cables need to be laid along complex paths such as wall corners, ceiling angles, and cable tray bends. When the fixed angle of the fixing device does not match the actual needs of these scenarios, the only way to adapt is to forcibly bend the cable or add additional adapters. This not only easily leads to signal transmission loss due to excessive bending of the cable, but also increases construction complexity and material costs. In addition, when the cable laying path requires temporary angle adjustments, the fixed device cannot adapt simultaneously, requiring removal and reinstallation, which seriously affects construction efficiency and has become a prominent problem restricting the flexibility and adaptability of security cabling. Utility Model Content
[0004] The purpose of this utility model is to provide a fixing device for security engineering wiring to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a fixing device for security engineering wiring, comprising a first support rod and a second support rod, wherein an adjustment mechanism is installed at one end of the first support rod and the second support rod close to each other, an installation mechanism is installed at the top of the second support rod, a right-angle limiting block is fixedly connected to the left side of the top of the second support rod, and a transverse limiting strip is fixedly connected to the left side of the bottom of the second support rod;
[0006] The adjustment mechanism includes a first mounting bracket, which is fixedly connected to the left side of the second support rod. A rotating shaft is fixedly connected to the left side of the first mounting bracket. Ratchets are fixedly connected to both the front and rear ends of the second mounting bracket. The second mounting bracket is fixedly connected to the bottom of the first support rod. A placement groove is fixedly connected to the outside of the first support rod near the bottom. A limit rod is slidably connected in the middle of the placement groove. A limit piece is fixedly connected to the bottom of the placement groove. A spring is sleeved on the top of the limit piece. A lifting strip is fixedly connected to the top of the limit rod. A ratchet is fixedly connected to the bottom of the limit rod.
[0007] Preferably, the bottom of the second mounting bracket is provided with a rotating hole, and the second mounting bracket is rotatably connected to the rotating hole.
[0008] Preferably, the left side of the right-angle limiting block contacts the right side of the first support rod, and the lateral limiting strip extends to the left to the position of the first support rod.
[0009] Preferably, the ratchet is engaged with the outer ring of the ratchet, and the upper helical teeth of the ratchet are bent toward the direction of the second support rod, with the bending direction of the ratchet being opposite to that of the upper helical teeth of the ratchet.
[0010] Preferably, the installation mechanism includes a fixing sleeve, which is snapped onto the top of the second support rod, and a bolt is installed on the right side of the fixing sleeve.
[0011] Preferably, the second support rod has a snap-fit hole at its top, and the bottom of the fixing sleeve is fixedly connected to a snap-fit pin. The bottom of the snap-fit pin is frustoconical, and the fixing sleeve is snapped into the snap-fit hole at the top of the second support rod by the snap-fit pin.
[0012] Preferably, the right side of the fixing sleeve has a gap, a pad is provided between the gaps, a through hole is provided in the middle of the pad, the bolt passes through the through hole and extends to the bottom right side of the fixing sleeve, and is threadedly connected to the nut.
[0013] Compared with the prior art, this utility model provides a convenient fixing device for wiring in security engineering, which has the following advantages:
[0014] 1. This convenient fixing device for security engineering cabling features an adjustment mechanism that allows for precise adjustment and locking of the fixing device's angle, solving the problem of poor scene adaptability caused by the fixed angle of existing devices. The first and second support rods rotate relative to each other via a rotating shaft. When angle adjustment is needed, pulling the lifting bar upwards moves the limiting rod upwards along the placement groove, compressing the spring of the limiting plate and disengaging the bottom ratchet from the ratchet. At this time, the first or second support rod can be rotated until the desired angle is reached (such as a wall corner, ceiling angle, etc.). After releasing the lifting bar, the spring returns to its original position, pushing the limiting rod downwards, and the ratchet re-engages into the helical teeth of the ratchet's outer ring. The angle is locked by utilizing the opposite bending direction of the ratchet and the ratchet. The right-angle limiting block and the horizontal limiting bar further limit excessive rotation, ensuring the stability of angle adjustment. This design eliminates the need for forcibly bending cables or adding adapters, reducing signal transmission loss and adapting to various complex laying scenarios.
[0015] At the same time, when the first support rod and the second support rod are close to 90 degrees to each other, the ratchet helical teeth bend towards the second support rod and bend in the opposite direction. Therefore, there is no need to pull the lifting bar. You can simply turn the first support rod and the second support rod to adjust the angle.
[0016] The right-angle limiting block limits the right-angle angle between the first support rod and the second support rod;
[0017] The lateral limiting strip limits the lateral angle of the first and second support rods to prevent them from flipping in the opposite direction.
[0018] 2. This convenient fixing device for security cabling projects features a coordinated installation and adjustment mechanism that ensures reliable fixing while allowing for angle adjustment, solving the problem of unstable fixing after angle adjustment. The working principle is as follows: In the installation mechanism, the fixing sleeve engages with the snap-fit hole at the top of the second support rod via a frustum-shaped snap-fit pin at the bottom, achieving initial positioning. When the bolts are tightened, the gap on the right side of the fixing sleeve contracts, and the pad enhances the clamping force, ensuring the fixing sleeve firmly holds the cable. After the adjustment mechanism completes the angle setting, the installation mechanism adapts synchronously with the angle. The double fixing by bolts and snap-fit pins ensures that the cable remains stably laid even in non-right-angle scenarios such as tilts and corners. This coordinated "adjustment + fixing" design avoids the hassle of disassembly and reinstallation after angle adjustment, reduces construction steps and material costs, and significantly improves the flexibility and construction efficiency of security cabling.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0027] This utility model provides the following technical solution:
[0028] Example 1
[0029] Please see Figure 1-4 A fixing device for facilitating wiring in security engineering includes a first support rod 1 and a second support rod 4. An adjustment mechanism 2 is installed at one end of the first support rod 1 and the second support rod 4 close to each other. An installation mechanism 3 is installed on the top of the second support rod 4. A right-angle limiting block 5 is fixedly connected to the top left side of the second support rod 4. A horizontal limiting strip 6 is fixedly connected to the bottom left side of the second support rod 4.
[0030] The adjustment mechanism 2 includes a first mounting bracket 21, which is fixedly connected to the left side of the second support rod 4. A rotating shaft 22 is fixedly connected to the left side of the first mounting bracket 21. Ratchets 25 are fixedly connected to both the front and rear ends of the second mounting bracket 23. The second mounting bracket 23 is fixedly connected to the bottom of the first support rod 1. A placement groove 29 is fixedly connected to the outside of the first support rod 1 near the bottom. A limit rod 27 is slidably connected in the middle of the placement groove 29. A limit piece 271 is fixedly connected to the bottom of the placement groove 29. A spring 28 is sleeved on the top of the limit piece 271. A lifting strip 24 is fixedly connected to the top of the limit rod 27. A ratchet 26 is fixedly connected to the bottom of the limit rod 27.
[0031] The adjustment mechanism 2 enables precise adjustment and locking of the fixed device angle, solving the problem of poor scene adaptability caused by the fixed angle of existing devices. The first support rod 1 and the second support rod 4 achieve relative rotation through the rotating shaft 22. When the angle needs to be adjusted, the lifting strip 24 is pulled upward, which drives the limiting rod 27 to move upward along the placement groove 29. The limiting plate 271 compresses the spring 28, causing the bottom ratchet 26 to disengage from the ratchet 25. At this time, the first support rod 1 or the second support rod 4 can be rotated until the desired angle is reached (such as a wall corner, a ceiling angle, etc.). After releasing the lifting strip 24, the spring 28 returns to its original position and pushes the limiting rod 27 downward. The ratchet 26 re-engages into the helical teeth of the outer ring of the ratchet 25. The angle is locked by utilizing the opposite bending direction of the ratchet 26 and the ratchet 25. The right-angle limiting block 5 and the horizontal limiting strip 6 further limit excessive rotation and ensure the stability of the angle adjustment. This design eliminates the need for forcibly bending cables or adding adapters, reduces signal transmission loss, and is suitable for various complex laying scenarios.
[0032] At the same time, when the first support rod 1 and the second support rod 4 are close to each other at an angle of 90 degrees, the ratchet 25 bends towards the second support rod 4 and the ratchet 26 bends in the opposite direction. Therefore, there is no need to pull the lifting bar 24. You can adjust the angle by simply turning the first support rod 1 and the second support rod 4.
[0033] The right-angle limiting block 5 limits the right-angle angle between the first support rod 1 and the second support rod 4;
[0034] The lateral limiting strip 6 limits the lateral angle of the first support rod 1 and the second support rod 4 to prevent them from flipping in the opposite direction.
[0035] The second mounting bracket 23 has a rotating hole at its bottom, and the second mounting bracket 23 is rotatably connected to the rotating hole.
[0036] The left side of the right-angle limiting block 5 contacts the right side of the first support rod 1, and the lateral limiting strip 6 extends to the left to the position of the first support rod 1.
[0037] Ratchet 26 engages with the outer ring of ratchet 25. The upper helical teeth of ratchet 25 bend towards the second support rod 4, and the bending direction of ratchet 26 is opposite to that of the upper helical teeth of ratchet 25.
[0038] Example 2
[0039] Please see Figure 1-4 Furthermore, based on Embodiment 1, the installation mechanism 3 further includes a fixing sleeve 33, which is snapped onto the top of the second support rod 4, and a bolt 34 is installed on the right side of the fixing sleeve 33.
[0040] The second support rod 4 has a snap-fit hole 31 at the top, and the bottom of the fixing sleeve 33 is fixedly connected to a snap-fit pin 32. The bottom of the snap-fit pin 32 is frustoconical, and the fixing sleeve 33 is snapped into the snap-fit hole 31 at the top of the second support rod 4 through the snap-fit pin 32.
[0041] The right side of the fixing sleeve 33 has a gap, and a pad 35 is placed between the gaps. A through hole is opened in the middle of the pad 35. The bolt 34 passes through the through hole and extends to the bottom right side of the fixing sleeve 33, and is threadedly connected to the nut.
[0042] The installation mechanism 3 and the adjustment mechanism 2 work together to ensure reliable fixation while adjusting the angle, solving the problem of unstable fixation after angle adjustment. The working principle is as follows: In the installation mechanism 3, the fixing sleeve 33 engages with the snap-fit hole 31 at the top of the second support rod 4 via the bottom frustum-shaped snap-fit pin 32, achieving initial positioning. When the bolt 34 is tightened, the gap on the right side of the fixing sleeve 33 contracts, and the pad 35 enhances the clamping force, ensuring the fixing sleeve 33 firmly holds the cable. After the adjustment mechanism 2 completes the angle setting, the installation mechanism 3 can adapt synchronously with the angle. Through the double fixation of the bolt 34 and the snap-fit pin 32, it ensures that the cable remains stably laid even in non-right-angle scenarios such as tilts and corners. This collaborative design of "adjustment + fixation" avoids the hassle of disassembly and reinstallation after angle adjustment, reduces construction steps and material costs, and significantly improves the flexibility and construction efficiency of security cabling.
[0043] In actual operation, when this device is used, the adjustment mechanism 2 achieves precise adjustment and locking of the fixed device angle, solving the problem of poor scene adaptability caused by the fixed angle of the existing device. The first support rod 1 and the second support rod 4 achieve relative rotation through the rotating shaft 22. When the angle needs to be adjusted, the lifting bar 24 is pulled upward, which drives the limiting rod 27 to move upward along the placement groove 29. The limiting plate 271 compresses the spring 28, causing the bottom ratchet 26 to disengage from the ratchet 25. At this time, the first support rod 1 or the second support rod 4 can be rotated until the desired angle is reached (such as the corner of the wall, the oblique angle of the ceiling, etc.). After releasing the lifting bar 24, the spring 28 returns to its original position and pushes the limiting rod 27 downward. The ratchet 26 re-engages into the oblique teeth of the outer ring of the ratchet 25. The angle is locked by utilizing the characteristic that the ratchet 26 and the ratchet 25 have opposite bending directions. The right-angle limiting block 5 and the horizontal limiting bar 6 further limit excessive rotation and ensure the stability of the angle adjustment. This design eliminates the need for forcibly bending cables or adding adapters, reducing signal transmission loss and making it suitable for various complex laying scenarios.
[0044] At the same time, when the first support rod 1 and the second support rod 4 are close to each other at an angle of 90 degrees, the ratchet 25 bends towards the second support rod 4 and the ratchet 26 bends in the opposite direction. Therefore, there is no need to pull the lifting bar 24. You can adjust the angle by simply turning the first support rod 1 and the second support rod 4.
[0045] The right-angle limiting block 5 limits the right-angle angle between the first support rod 1 and the second support rod 4;
[0046] The lateral limiting strip 6 limits the lateral angle of the first support rod 1 and the second support rod 4 to prevent them from flipping in the opposite direction.
[0047] The installation mechanism 3 and the adjustment mechanism 2 work together to ensure reliable fixation while adjusting the angle, solving the problem of unstable fixation after angle adjustment. The working principle is as follows: In the installation mechanism 3, the fixing sleeve 33 engages with the snap-fit hole 31 at the top of the second support rod 4 via the bottom frustum-shaped snap-fit pin 32, achieving initial positioning. When the bolt 34 is tightened, the gap on the right side of the fixing sleeve 33 contracts, and the pad 35 enhances the clamping force, ensuring the fixing sleeve 33 firmly holds the cable. After the adjustment mechanism 2 completes the angle setting, the installation mechanism 3 can adapt synchronously with the angle. Through the double fixation of the bolt 34 and the snap-fit pin 32, it ensures that the cable remains stably laid even in non-right-angle scenarios such as tilts and corners. This collaborative design of "adjustment + fixation" avoids the hassle of disassembly and reinstallation after angle adjustment, reduces construction steps and material costs, and significantly improves the flexibility and construction efficiency of security cabling.
