Description

Technical Field

[0001] The utility model relates to a safety net, in particular to a novel simple buckle device for a safety net. Background Art

[0002] During construction, building scaffolding, especially external scaffolding, needs to be hung with dense safety nets to prevent workers or objects from falling from high altitudes and causing safety accidents. It also plays a certain role in blocking wind and suppressing dust. At present, workers on the construction site use thin iron wire to tie and tighten the safety net on the scaffolding steel pipe. Although this operation is simple and convenient, the thin iron wire is easily affected by the rainy season and humid environment, easy to rust, low strength, and easy to break. Generally, in the natural environment from June to September, it will rust and break, causing the safety net to fall off locally or even on a large scale, which is easy to cause gravel objects to fall, posing a safety hazard, and needs to be reworked and re-tied later. At the same time, due to the large scale of the safety net layout on the construction site, the safety net can be seen falling off everywhere, and it is difficult to repair all of them even if they are repaired. Even if it is replaced with aluminum wire, thick iron wire or plastic straps, the materials are all disposable and cannot be reused, resulting in waste. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a novel simple safety net hanging buckle device which is simple and efficient to operate and durable.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A novel simple device for hanging a safety net is characterized in that it comprises a plurality of sets of snap rings which are sleeved on the horizontal bars and vertical bars of a scaffold; an upper hook is fixed on the upper end of the snap ring and a lower hook is fixed on the lower end of the snap ring, and the safety net is hung on the upper hook or the lower hook through the hanging hole;

[0006] The clamp ring is provided with an opening, and the buckle rod opens or closes the opening;

[0007] One end of the buckle rod is rotatably connected to the snap ring, and the other end of the buckle rod is locked with the snap ring through a locking mechanism.

[0008] The buckle rod is arc-shaped and forms an annular structure with the clamping ring in a closed state, and the inner diameter of the annular structure matches the outer diameter of the cross rod and the vertical rod.

[0009] The locking mechanism comprises a curved hook, which is hooked with a buckle ring on the buckle rod.

[0010] Each group of snap rings is connected in series with the snap rings on the buckle rod via a connecting ring.

[0011] The locking mechanism includes an elastic rod, which is slidably arranged in the chute at the other end of the opening of the snap ring. The tail end of the elastic rod is connected to the bottom surface of the chute through a first spring. An annular limiting groove is provided in the middle of the elastic rod, and the annular limiting groove is clamped or disengaged from the elastic pull rod on one side; correspondingly, a clamping groove is provided at the end of the buckle rod. When the annular limiting groove is disengaged from the elastic pull rod, the elastic rod extends into the clamping groove.

[0012] A control rod is fixed on the elastic rod, and the upper end of the control rod freely extends out of the limiting groove of the snap ring.

[0013] The multiple snap rings on the cross bar and the multiple snap rings on the vertical rod are respectively connected in series by a tether.

[0014] The utility model provides a new type of simple device for hanging safety nets, which has the following technical effects:

[0015] 1) By adopting a detachable snap ring, the safety net can be directly hung, and the construction operation is convenient. The installer only needs to perform a few simple operations and can complete it in a short time. The device can also effectively prevent slipping, which is safe and effective.

[0016] 2) The structure of this device is simple, easy to manufacture, and has a low cost. It is made of stainless steel or galvanized material, which can effectively prevent water, rust, and breakage, and has strong durability.

[0017] 3) By connecting the snap rings in series with a tether, the number of connected snap rings can be freely increased or decreased, which can be effectively recycled and conveniently stored, avoiding scattered loss, and can be reused, which is green and environmentally friendly.

[0018] 4) By adopting a rubber sleeve, the rubber sleeve can effectively prevent slipping after being fixed on the steel pipe of the scaffolding with the snap ring. Therefore, it can not only be applied to common fastener-type steel pipe scaffolding, but also to other types of scaffolding, such as socket steel pipe scaffolding, bowl-coupled scaffolding, and sleeve-coupled scaffolding. It can not only be suitable for hanging vertical safety nets, but also for horizontal, inclined, and irregular curved surfaces, etc. The applicable range is relatively wide.

[0032] Embodiment 1

[0033] As Figures 1-4 shown, a new type of simple device for hanging a safety net includes a snap ring 1. The snap ring 1 is a metal ring, and a partial break is provided with an opening, which facilitates the snap ring 1 to be sleeved on the cross bar 11 and vertical rod 12 of the scaffold. At one end of the two ends of the opening of the snap ring 1, a connecting ring 4 is provided, and at the other end, a hook 7 is provided. Buckle rings 6 are provided at both ends of the buckle rod 5. The buckle ring 6 at one end of the buckle rod 5 is connected in series with the connecting ring 4, and the buckle ring 6 at the other end of the buckle rod 5 is hooked to the hook 7, so that the snap ring 1 can be fastened to the cross bar 11 or the vertical rod 12.

[0034] An upper hook 3 is fixed to the upper end of the snap ring 1, and a lower hook 2 is fixed to the lower end. The upper hook 3 and the lower hook 2 are used to hang the safety net 14.

[0035] Multiple groups of snap rings 1 are provided, and a tether 9 passes through the connecting rings 4 on multiple groups of snap rings 1, thereby realizing the connection of multiple snap rings 1 together, which is convenient for use and recycling storage and avoids scattered loss.

[0036] The material of the snap ring 1 is metal, specifically stainless steel wire or galvanized iron wire, with a thickness ≥ 2 mm, having good waterproof and rust-proof performance.

[0037] The snap ring 1 is wrapped with a rubber sleeve 8. The rubber sleeve 8 is relatively thin with a thickness ≤ 2 mm. After the snap ring 1 is fixed on the steel pipes 11 and 12, the rubber sleeve 8 can prevent it from slipping.

[0038] The upper hooks 3 and the lower hooks 2 are symmetrically arranged and have a diameter of 2 cm to 4 cm.

[0039] The tether 9 is made of cotton thread or hemp rope or steel wire, with a width ≤ 2 mm.

[0040] The buckle rod 5 is an arc-shaped rod, and the bending curvature is consistent with the cross bars 11 and the vertical bars 12 of the scaffold.

[0041] Working principle and process:

[0042] Setp1: Serial connection of the snap rings 1. Connect multiple snap rings 1 in series with a tether 9 through a connecting ring 4. The quantity is roughly determined according to the number of hanging holes 10 on the long side and the short side of the on-site safety net 14. After the series connection, the end of the tether 9 is knotted to prevent the snap rings 1 from falling apart.

[0043] Setp2: Fixing of the snap rings 1. Pass each snap ring 1 through the opening of the snap ring 1 and fix it on the cross bars 11 and the vertical bars 12 of the scaffold. After adjusting the position, buckle the buckle rod 5 to fasten it and prevent it from slipping.

[0044] Setp3: Hanging and buckling of the safety net 14. Align the hanging holes 10 of the safety net 14 with the snap ring hooks 2 and 3 one by one and buckle them on. Fully tension the safety net 14 to complete its hanging.

[0045] Setp4: Dismantling and recycling of the device. When the device is dismantled, first dismantle the safety net 14. After removing the entire safety net 14 from the upper hooks 3 and the lower hooks 2, pull the buckle rod 5 on the snap ring 1 to release the entire snap ring, and then carefully pull it out from the cross bars 11 and the vertical bars 12. After pulling out the subsequent snap rings 1 one by one as required, recycle and store the entire strip of snap rings 1.

[0046] Embodiment 2

[0047] A new type of simple device for hanging and buckling a safety net includes multiple groups of snap rings 1. The multiple groups of snap rings 1 are sleeved on the cross bars 11 and the vertical bars 12 of the scaffold. An upper hook 3 is fixed at the upper end of the snap ring 1, and a lower hook 2 is fixed at the lower end. The upper hook 3 and the lower hook 2 are used to hang and buckle the safety net 14.

[0048] Each group of snap rings 1 is a metal circular ring, and is partially disconnected with an opening. A buckle rod 5 is installed at the opening, and the buckle rod 5 opens or closes the opening.

[0049] Different from Embodiment 1, the snap ring 1 is made of an elastic metal sheet. One end of the buckle rod 5 is rotatably connected to the open end of the snap ring 1 through a pin shaft with a return spring, and the other end of the buckle rod 5 is clamped and locked to the other end of the snap ring 1 through another locking mechanism.

[0050] Specifically, as Figures 7-10 shown, the locking mechanism includes an elastic rod 1.1 which is slidably arranged in a chute 1.2 at the other open end of the snap ring 1. The tail end of the elastic rod 1.1 is connected to the bottom surface of the chute 1.2 through a first spring 1.3. An annular limiting groove 1.4 is provided in the middle of the elastic rod 1.1. A clamping groove is provided on the snap ring 1 in a direction perpendicular to the chute 1.2. An elastic pull rod 1.5 is slidably arranged in the clamping groove. The elastic pull rod 1.5 provides a thrust force towards the annular limiting groove 1.4 through a second spring. When the elastic rod 1.1 retracts into the chute 1.2, the annular limiting groove 1.4 is clamped with the elastic pull rod 1.5. In addition, a clamping groove 1.6 is provided at the end of the buckle rod 5, and the clamping groove 1.6 is opposite to the elastic rod 1.1. When the elastic pull rod 1.5 is pulled outwards and the elastic pull rod 1.5 is disengaged from the annular limiting groove 1.4, under the push of the first spring 1.3, the elastic rod 1.1 extends into the clamping groove 1.6. Thus, clamping is achieved, and the buckle rod 5 is closed.

[0051] In addition, a control rod 1.7 is fixed on the elastic rod 1.1, and a limiting groove 1.8 is provided on the snap ring 1 at this position. The control rod 1.7 freely extends out of the limiting groove 1.8. The length of the limiting groove 1.8 is determined according to the actual situation. When the control rod 1.7 is located at the left extreme position of the limiting groove 1.8, the elastic rod 1.1 is clamped with the clamping groove 1.6 to lock the buckle rod 5. When the control rod 1.7 is located at the right extreme position of the limiting groove 1.8, the elastic rod 1.1 retracts, and the elastic pull rod 1.5 is clamped and limited with the annular limiting groove 1.4. At this time, the buckle rod 5 is unlocked and the snap ring 1 can be opened.

[0052] During operation, the snap ring 1 is clamped on the cross bar 11 and the vertical bar 12 of the scaffolding. After adjusting the position, the buckle rod 5 is closed. Then, the elastic pull rod 1.5 is pulled outwards, the elastic pull rod 1.5 is disengaged from the annular limiting groove 1.4, and the elastic rod 1.1 is clamped with the clamping groove 1.6, so as to be locked. Then, subsequent net hanging operations are carried out. When the snap ring 1 needs to be disassembled, the control rod 1.7 is pushed to the right, the elastic rod 1.1 is disengaged from the clamping groove 1.6 and retracts into the chute 1.2. At this time, the annular limiting groove 1.4 is opposite to the elastic pull rod 1.5, and the elastic pull rod 1.5 is clamped with the annular limiting groove 1.4, thus completing the unlocking, and the snap ring 1 can be pulled out. By adopting the second method, the locking state is more stable and the operation is more convenient.
