Description

Technical Field

[0001] This utility model relates to the field of safety fence technology, specifically a safety fence for construction projects. Background Technology

[0002] With the rapid advancement of urbanization, the scale and number of construction projects are increasing daily, making safety protection at construction sites a growing concern. Safety fences, as a fundamental component of the construction site safety protection system, directly affect the safety of construction workers and the stability of the surrounding environment.

[0003] Currently, most construction safety fences on the market use traditional bolted or welded connections. Bolted fences require a significant amount of time for alignment and tightening during installation, necessitating various tools such as wrenches and screwdrivers. This is not only inefficient but also poses a risk of decreased fence stability due to loose bolts. While welding can ensure a certain level of connection strength, the welding process demands high skill from workers, and the fences are difficult to reuse after disassembly, resulting in resource waste. Utility Model Content

[0004] In view of the shortcomings of existing technologies, this utility model provides a safety fence for construction projects.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A safety fence for construction projects, comprising:

[0007] Fence board;

[0008] The posts are symmetrically arranged on both sides of the fence panel;

[0009] A sleeve, fixed to the side of the column, with an opening at the top;

[0010] L-shaped rods are fixed to both sides of the fence panel and inserted into the sleeves;

[0011] The first truncated cone is fixed at the middle of the bottom end of the L-shaped rod, and its bottom diameter is smaller than its top diameter;

[0012] The fixed plate is fixed inside the sleeve and is located within the insertion stroke of the first frustum;

[0013] Several elastic claws are arranged in a circumferential array on the top of the fixed disk, and can be elastically deformed outward;

[0014] The threaded rod is connected to the sleeve in a lifting manner, and its top end passes through the fixed plate and extends into the inner side of the elastic claw.

[0015] The second frustum is rotatably connected to the top of the threaded rod;

[0016] When the L-shaped rod is inserted into the sleeve, the first truncated cone compresses the elastic claw, causing it to deform outward until the elastic claw engages with the upper surface of the first truncated cone, thus locking the L-shaped rod upward. When the rotating threaded rod moves downward, the second truncated cone compresses the elastic claw, causing it to deform again, thereby releasing the lock on the first truncated cone.

[0017] Preferably, the end of the elastic claw is provided with an inwardly inclined guide surface, which slides in engagement with the conical surface of the first frustum.

[0018] Preferably, the second truncated cone is a cylindrical truncated cone with a diameter larger than the inner diameter of the middle part of the elastic claw. The second truncated cone moves downward to compress the elastic claw and deform it to separate from the first truncated cone.

[0019] Preferably, the second truncated cone is a truncated cone, and the taper of the truncated cone is the same as the taper of the inner surface of the elastic claw. The second truncated cone moves down and compresses the elastic claw to deform and separate from the first truncated cone.

[0020] Preferably, the sleeve has a threaded hole that mates with the threaded rod.

[0021] Preferably, a limiting ring is fixed to the top of the L-shaped rod, and the outer diameter of the limiting ring is larger than the inner diameter of the sleeve.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. The L-shaped bars on both sides of the fence panel can be inserted into the sleeves on the side of the post. This structural design makes the installation of the fence panel and the post simple. The installation can be completed by the cooperation between the parts, without complicated operation steps.

[0024] 2. Secure connection: The first truncated cone at the bottom of the L-shaped rod engages with the elastic claw. When the L-shaped rod is inserted into the sleeve, the first truncated cone presses against the elastic claw. The elastic claw resets and locks the first truncated cone under its own elastic force, thereby locking the L-shaped rod in the upward direction and thus firmly fixing the fence panel to the post, ensuring the overall stability of the fence and preventing the fence panel from loosening.

[0025] 3. Easy disassembly: By rotating the threaded rod, the second truncated cone moves down and squeezes the elastic claw, causing the elastic claw to deform and separate from the first truncated cone, thus easily pulling out the L-shaped rod and separating the fence panel from the post. The disassembly operation is simple and quick. Attached Figure Description

[0035] Example

[0036] like Figure 1-6 As shown, a safety fence for construction projects includes:

[0037] Fence Panel 1: As the main protective component of the safety fence, it is used to isolate the construction area from the external environment.

[0038] Post 2: Symmetrically positioned on both sides of fence panel 1, providing vertical support for the fence and ensuring the overall stability of the fence.

[0039] Sleeve 21: Fixed to the side of post 2, with an opening at the top, used to insert L-shaped rod 11, and is a key component for connecting fence panel 1 and post 2.

[0040] L-shaped rod 11: Fixed to both sides of the fence panel 1, it can be inserted into the sleeve 21 and, through cooperation with other parts in the sleeve 21, enables the fence panel 1 to be fixed and disassembled.

[0041] First truncated cone 12: Fixed to the middle of the bottom end of L-shaped rod 11, with a bottom diameter smaller than the top diameter. During the process of L-shaped rod 11 being inserted into sleeve 21, it compresses elastic claw 23 to achieve locking function.

[0042] Fixed plate 22: Fixed inside the sleeve 21, located within the insertion stroke of the first truncated cone 12, providing an installation base for the elastic claw 23.

[0043] Elastic claws 23: Circumferentially arrayed on the top of the fixed disk 22, capable of elastic deformation outwards. Its end has an inwardly inclined guide surface that slides in cooperation with the conical surface of the first frustum 12, achieving automatic engagement when the L-shaped rod 11 is inserted, and locking the L-shaped rod 11 from rising.

[0044] Threaded rod 24: It is connected to the sleeve 21 through the threaded hole on the sleeve 21. The top end passes through the fixed plate 22 and extends into the inner side of the elastic claw 23. Rotating the threaded rod 24 can control the second truncated cone 25 to move up and down, thereby realizing the squeezing and releasing of the elastic claw 23, achieving the purpose of locking and unlocking. The second truncated cone 25 and the threaded rod 24 are rotatably connected by bearings.

[0045] The second frustum 25 is rotatably connected to the top of the threaded rod 24 via a bearing, and can be either a cylindrical frustum or a conical frustum. When a cylindrical frustum is used, its diameter is larger than the inner diameter of the middle part of the elastic claw 23; when a conical frustum is used, the taper of the frustum is the same as the taper of the inner surface of the elastic claw 23. When the second frustum 25 moves downward, it presses against the elastic claw 23, causing it to deform and disengage from the first frustum 12, thus releasing the lock on the L-shaped rod 11.

[0046] Limiting ring 13: Fixed to the top of L-shaped rod 11, with an outer diameter larger than the inner diameter of sleeve 21, used to limit the depth of L-shaped rod 11 inserted into sleeve 21, and prevent L-shaped rod 11 from being over-inserted and damaging the internal structure.

[0047] During installation, the L-shaped rods 11, fixed to the two edges of the fence panel 1, are aligned with the sleeves 21 on the sides of the post 2 and inserted. As the L-shaped rods 11 are inserted deeper, the first frustum 12 at its bottom end contacts the elastic claw 23. Since the bottom diameter of the first frustum 12 is smaller than its top diameter, as insertion continues, the conical surface of the first frustum 12 will compress the elastic claw 23, causing it to elastically deform outward. At the same time, the inwardly inclined guide surface at the end of the elastic claw 23 slides and engages with the conical surface of the first frustum 12. When the L-shaped rod 11 is inserted to the appropriate position, the elastic claw 23 resets under its own elastic force, locking the first frustum 12 and thus locking the L-shaped rod 11 in the upward direction, thereby firmly fixing the fence panel 1 to the post 2. At this time, the limiting ring 13 at the top of the L-shaped rod 11, because its outer diameter is larger than the inner diameter of the sleeve 21, restricts the L-shaped rod 11 from being over-inserted into the sleeve 21, protecting the internal structure from damage.

[0048] When it is necessary to disassemble the fence panel 1, the threaded rod 24, which is connected to the sleeve 21 for lifting, is rotated. Since the top of the threaded rod 24 passes through the fixed plate 22 and extends into the inner side of the elastic claw 23, and the second frustum 25, which is rotatably connected to the top of the threaded rod 24 via a bearing, is located inside the elastic claw 23, the second frustum 25 moves downward as the threaded rod 24 rotates. If the second frustum 25 is a cylindrical frustum, its diameter is larger than the inner diameter of the elastic claw 23, and during the downward movement, it will compress the elastic claw 23 to deform outward; if it is a conical frustum, because its taper is the same as the taper of the inner surface of the elastic claw 23, it will also cause the elastic claw 23 to expand outward. When the elastic claw 23 deforms to the point of disengaging from the first frustum 12, the L-shaped rod 11 can be easily pulled upward, separating the fence panel 1 from the post 2 and completing the disassembly operation.

[0049] Easy installation: The L-shaped rods 11 on both sides of the fence panel 1 can be inserted into the sleeves 21 on the side of the post 2. This structural design makes the installation of the fence panel 1 and the post 2 simple. The installation can be completed by the cooperation between the parts, without complicated operation steps.

[0050] Secure connection: The first frustum 12 at the bottom of the L-shaped rod 11 engages with the elastic claw 23. When the L-shaped rod 11 is inserted into the sleeve 21, the first frustum 12 presses against the elastic claw 23. Under its own elastic force, the elastic claw 23 resets and locks the first frustum 12, thereby locking the L-shaped rod 11 in the upward direction and thus firmly fixing the fence panel 1 to the post 2, ensuring the overall stability of the fence and preventing the fence panel 1 from loosening.

[0051] Structural protection: The outer diameter of the limiting ring 13 at the top of the L-shaped rod 11 is larger than the inner diameter of the sleeve 21, which can limit the depth of the L-shaped rod 11 inserted into the sleeve 21, prevent the L-shaped rod 11 from being over-inserted and damaging the internal structure of the sleeve 21, and extend the service life of the fence.

[0052] Easy disassembly: By rotating the threaded rod 24, the second truncated cone 25 moves down and squeezes the elastic claw 23, causing the elastic claw 23 to deform and separate from the first truncated cone 12, thereby easily pulling out the L-shaped rod 11 and separating the fence panel 1 from the post 2. The disassembly operation is simple and quick.

[0053] Flexible design: The second frustum 25 can be a cylindrical frustum or a conical frustum. The diameter of the cylindrical frustum is larger than the inner diameter of the elastic claw 23. The taper of the conical frustum is the same as the taper of the inner surface of the elastic claw 23. This design allows for the selection of a suitable shape for the second frustum 25 according to actual needs, so as to achieve effective compression and release of the elastic claw 23.

[0054] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
