Description

Technical Field

[0001] This utility model relates to the field of construction site protective fencing technology, specifically a construction site protective fencing that can be spliced ​​at multiple angles. Background Technology

[0002] Construction is a complex and systematic process that covers all stages from project planning and design to final delivery. During construction, fencing is required. Fencing is a plate-like device used to isolate the construction site from the external environment. Fencing can effectively prevent dust and garbage generated at the construction site from polluting the external environment, and at the same time, it can prevent outsiders from accidentally entering the construction site and getting injured.

[0003] The CN 212773771 U publication describes a construction protective fence that can be spliced ​​at multiple angles. This allows for improved splicing stability and a wider range of applicability for the device. It can also collect rainwater to clean residual dust on the surface of the protective fence, facilitating its later recycling.

[0004] This construction site protective fence, which can be spliced ​​at multiple angles, requires pulling down a locking rod to rotate the fence. However, when the fence is limited by the locking rod, the angle adjustment is not flexible enough. The locking rod can only be limited at a specific angle corresponding to the locking groove. If the fence angle needs to be finely adjusted on the construction site, the locking rod limit may not meet the requirements. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a protective fence for construction that can be spliced ​​at multiple angles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction protective fence that can be spliced ​​at multiple angles, including casters, a load-bearing plate fixedly connected to the top of the casters, a support frame fixedly connected to the middle of the top of the load-bearing plate, a rotating installation mechanism provided inside the support frame, a fence body provided outside the rotating installation mechanism, and a limit mechanism provided in the middle of the inner side of the support frame.

[0007] The rotating mounting mechanism includes a rotating component and a mounting component. The rotating component is disposed inside the support frame, and the mounting component is disposed inside the rotating component.

[0008] The rotating assembly includes a rotating rod, the bottom of which is rotatably connected to the top of a load-bearing plate, the top of which is rotatably connected to the inner side of a support frame, a rotating plate fixedly connected to the periphery of the rotating rod, a worm gear fixedly connected to the top of the rotating rod, a worm meshing with the front of the worm gear, a first support plate rotatably connected to the left periphery of the worm, the first support plate being fixedly connected to the top left side of the support frame, a second support plate rotatably connected to the right side of the worm, the second support plate being fixedly connected to the top center of the support plate, and a support member fixedly connected to the bottom of the worm gear.

[0009] Preferably, the top of the support frame has a circular groove corresponding to the movement trajectory of the support member, and the support member is slidably connected inside the circular groove. The circular groove allows the support member to rotate on the top of the support frame, and the support member can support the worm gear, making the worm gear more stable during rotation.

[0010] Preferably, the installation assembly includes a connecting frame, which is fixedly connected to the back end of the rotating plate. A limiting plate is slidably connected to the inner side of the connecting frame. A sliding rod is fixedly connected to the back end of the limiting plate. A pull plate is fixedly connected to the back end of the sliding rod. An insert block is fixedly connected to the front of the limiting plate. An insert plate is inserted around the insert block. The insert plate is fixedly connected to the inner side of the enclosure body. A spring is sleeved around the sliding rod.

[0011] Preferably, the back end of the spring is fixedly connected to the inner back end of the connecting frame, and the front end of the spring is fixedly connected to the back end of the limiting plate. When the insert plate is inserted into the inner side of the rotating plate, the force on the pull plate is released, so that the limiting plate can drive the insert block to insert into the insert plate and limit the insertion plate.

[0012] Preferably, the inner side of the insert plate is provided with a rectangular groove corresponding to the position of the insert block, and the insert block is inserted into the rectangular groove. The rectangular groove allows the insert block to be inserted into the insert plate, thereby limiting the position of the insert plate.

[0013] Preferably, the limiting mechanism includes a rectangular plate, which is fixedly connected to the front of the support frame. A threaded rod is rotatably connected to the inner side of the rectangular plate, and a threaded plate is threadedly connected to the outer side of the threaded rod. A limiting rod is slidably connected to the inner back end of the threaded plate. A connecting plate is fixedly connected to the top and bottom of the limiting rod. The connecting plate is fixedly connected to the back end of the support frame. A slide bar is fixedly connected to the bottom of the threaded plate, and an anti-slip plate is fixedly connected to the bottom of the slide bar.

[0014] Preferably, the inner side of the load-bearing plate has a rectangular hole corresponding to the position of the slide bar, and the slide bar is slidably connected to the inner side of the rectangular hole. Through the rectangular hole, the slide bar can slide inside the load-bearing plate, allowing the anti-slip plate to move downwards to contact the ground, lifting the device and making it difficult for the device to be moved by the casters.

[0015] Compared with the prior art, this utility model provides a protective fence for construction sites that can be spliced ​​at multiple angles, and has the following beneficial effects:

[0016] 1. This construction protective fence, which can be spliced ​​at multiple angles, uses the meshing transmission of worm gear and worm wheel. Operators only need to turn the worm gear to easily drive the worm wheel and the rotating rod connected to it to rotate, thereby enabling the rotating plate fixed on the rotating rod to rotate at multiple angles. This allows the fence body to flexibly adjust its angle according to the actual needs of the construction site and adapt to various complex site layouts.

[0017] The insertion of the plug and the plate in the installation assembly makes the installation and disassembly of the fence body simple and quick. When the fence body needs to be installed, simply align the plug with the rectangular groove on the inside of the plate and insert it. The spring action on the limiting plate makes the plug firmly locked in the plate, ensuring the stability of the connection.

[0018] 2. This construction site protective fence can be spliced ​​at multiple angles. By rotating the threaded rod, the threaded plate will move up and down around the threaded rod. By adjusting the height of the threaded plate, the bottom anti-slip plate will be in close contact with the load-bearing plate. The friction of the anti-slip plate will firmly fix the fence body in the required position, preventing it from shifting due to external forces during use and ensuring the safety of the construction site.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-6 This utility model provides a technical solution: a construction protective fence that can be spliced ​​at multiple angles, including a caster wheel 1, a load-bearing plate 2 fixedly connected to the top of the caster wheel 1, a support frame 6 fixedly connected to the middle of the top of the load-bearing plate 2, a rotating installation mechanism 5 provided on the inner side of the support frame 6, a fence body 4 provided on the outer side of the rotating installation mechanism 5, and a limit mechanism 3 provided on the middle of the inner side of the support frame 6.

[0032] The rotating mounting mechanism 5 includes a rotating component 51 and a mounting component 52. The rotating component 51 is disposed inside the support frame 6, and the mounting component 52 is disposed inside the rotating component 51.

[0033] The rotating assembly 51 includes a rotating rod 511, the bottom of which is rotatably connected to the top of the load-bearing plate 2, and the top of which is rotatably connected to the inner side of the support frame 6. A rotating plate 512 is fixedly connected to the outer periphery of the rotating rod 511. A worm gear 515 is fixedly connected to the top of the rotating rod 511. A worm 513 is meshed with the front of the worm gear 515. A first support plate 514 is rotatably connected to the left periphery of the worm 513. The first support plate 514 is fixedly connected to the top left side of the support frame 6. A second support plate 516 is rotatably connected to the right side of the worm 513. The second support plate 516 is fixedly connected to the top middle of the support plate. A support member 517 is fixedly connected to the bottom of the worm gear 515.

[0034] Furthermore, a circular groove corresponding to the movement trajectory of the support member 517 is provided on the top of the support frame 6, and the support member 517 is slidably connected inside the circular groove. Through the circular groove, the support member 517 can rotate on the top of the support frame 6. The support member 517 can support the worm gear 515, making the worm gear 515 more stable during rotation.

[0035] Example 2

[0036] Please see Figure 1-6 Furthermore, based on Embodiment 1, the installation component 52 further includes a connecting frame 523, which is fixedly connected to the back end of the rotating plate 512. A limiting plate 524 is slidably connected to the inner side of the connecting frame 523. A sliding rod 526 is fixedly connected to the back end of the limiting plate 524. A pull plate 522 is fixedly connected to the back end of the sliding rod 526. An insert block 525 is fixedly connected to the front of the limiting plate 524. An insert plate 527 is inserted around the insert block 525. The insert plate 527 is fixedly connected to the inner side of the enclosure body 4. A spring 521 is sleeved around the sliding rod 526.

[0037] Furthermore, the back end of the spring 521 is fixedly connected to the inner back end of the connecting frame 523, and the front end of the spring 521 is fixedly connected to the back end of the limiting plate 524. When the insert plate 527 is inserted into the inner side of the rotating plate 512, the force on the pull plate 522 is released, so that the limiting plate 524 can drive the insert block 525 to be inserted into the insert plate 527, thereby limiting the insertion plate 527.

[0038] Furthermore, a rectangular groove corresponding to the position of the insert block 525 is provided on the inner side of the insert plate 527, and the insert block 525 is inserted into the rectangular groove. Through the rectangular groove, the insert block 525 can be inserted into the insert plate 527 to limit the position of the insert plate 527.

[0039] Example 3

[0040] Please see Figure 1-6Furthermore, based on Embodiment 1, the limiting mechanism 3 further includes a rectangular plate 37, which is fixedly connected to the front of the support frame 6. A threaded rod 35 is rotatably connected to the inner side of the rectangular plate 37. A threaded plate 34 is threadedly connected to the outer side of the threaded rod 35. A limiting rod 33 is slidably connected to the inner back end of the threaded plate 34. A connecting plate 32 is fixedly connected to the top and bottom of the limiting rod 33. The connecting plate 32 is fixedly connected to the back end of the support frame 6. A slide bar 36 is fixedly connected to the bottom of the threaded plate 34. An anti-slip plate 31 is fixedly connected to the bottom of the slide bar 36.

[0041] Furthermore, a rectangular hole corresponding to the position of the slide bar 36 is provided on the inner side of the load-bearing plate 2, and the slide bar 36 is slidably connected to the inner side of the rectangular hole. Through the rectangular hole, the slide bar 36 can slide inside the load-bearing plate 2, allowing the anti-slip plate 31 to move downward to contact the ground, lifting the device and making it difficult for the device to be moved by the caster wheel 1.

[0042] In actual operation, when this device is used, the universal wheel 1 is used to move the device to a suitable position. The rotating threaded rod 35 causes the threaded rod 35 to drive the slide bar 36 and the anti-slip plate 31 to move downward through the threaded plate 34, so that the bottom of the anti-slip plate 31 contacts the ground, lifting the device and making it difficult for the device to be moved by the universal wheel 1.

[0043] Pulling the pull plate 522 causes the pull plate 522 to drive the limiting plate 524 to compress the spring 521 via the slide rod 526, inserting the insert plate 527 inside the rotating plate 512. Releasing the force on the pull plate 522 causes the limiting plate 524 to drive the slide rod 526 and the insert block 525 to move, so that the insert block 525 is inserted into the insert plate 527, limiting the insert plate 527, so that the fence body 4 can be quickly installed inside the rotating plate 512.

[0044] When the angle of the enclosure body 4 needs to be adjusted, the worm gear 513 is manually rotated, causing the worm gear 513 to drive the worm wheel 515 to rotate. The worm wheel 515 then drives the rotating plate 512 to rotate via the rotating rod 511. The rotating plate 512 then drives the enclosure body 4 to rotate via the insert plate 527, allowing the angle of the enclosure body 4 to be adjusted. This device can flexibly adjust the angle according to the actual needs of the construction site and adapt to various complex site layouts.
