[0001] The utility model relates to the technical field of safety net experiments, in particular to a rotary safety net flame-retardant fixed experiment clamp. Background Art

[0002] Safety nets are a key piece of protective equipment for working at heights. Composed primarily of a net, side ropes, tethers, and tendons, they are renowned for their strength, lightness, and excellent thermal insulation and ventilation. Their primary function is to prevent people and objects from falling, thereby avoiding potential injuries.

[0003] With current manufacturing technology, safety nets undergo rigorous flame retardancy testing after production. However, due to the inherent flexibility of the safety net, securing it during testing presents a challenge. Typically, workers use clamps to hold and secure the safety net.

DETAILED DESCRIPTION

[0021] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0022] A rotating safety net flame-retardant fixed test clamp according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, a rotating safety net flame-retardant fixed test clamp according to an embodiment of the present invention includes a fixed shaft 10 and a clamping assembly 20.

[0024] The clamping assembly 20 is provided in multiple groups, and the multiple groups of clamping assemblies 20 are movably arranged on the fixed shaft 10. The clamping assembly 20 includes an outer sleeve 201, an upper fixing plate 202, a lower fixing plate 203, a pressing mechanism 204, a pushing mechanism 205 and a through slot 206.

[0025] The outer sleeve 201 is movably mounted on the fixed shaft 10, the upper fixed plate 202 is mounted on the outer sleeve 201, and the lower fixed plate 203 is mounted on the outer sleeve 201. A pressing mechanism 204 is mounted on the outer sleeve 201 and between the lower fixed plate 203 and the upper fixed plate 202. A through slot 206 is defined in the upper fixed plate 202. A pushing mechanism 205 is movably mounted within the through slot 206 and abuts against the pressing mechanism 204.

[0026] It should be noted that the fixed shaft 10 described in this embodiment is a circular shaft, and the outer sleeve 201 moves and rotates on the fixed shaft 10. A gap is left between the upper fixed plate 202 and the lower fixed plate 203. Therefore, when the safety net is subjected to a flame retardant test, the safety net is inserted between the upper fixed plate 202 and the lower fixed plate 203, and then the pushing mechanism 205 is pushed. The pushing mechanism 205 moves within a limited position in the through groove 206, and the pushing mechanism 205 abuts against the pressing mechanism 204 during the movement, so that the pressing mechanism 204 presses and fixes the safety net, thereby ensuring the stability of the safety net during the flame retardant test.

[0027] In one embodiment of the present invention, Figure 2 As shown, the pressing mechanism 204 includes an upper pressing plate 2041 , a reset component 2042 and an anti-slip component 2043 .

[0028] Among them, the upper pressure plate 2041 is rotatably set on the outer sleeve 201, the reset component 2042 is set at the connection between the upper pressure plate 2041 and the outer sleeve 201, and the anti-slip component 2043 is a plurality of groups, and the plurality of groups of anti-slip components 2043 are linearly arrayed on the bottom wall of the anti-slip component 2043.

[0029] It should be noted that the upper pressing plate 2041 is rotatably mounted on the outer sleeve 201 via an axis, and a reset component 2042 is sleeved on the axis. The reset component 2042 is a volute spring, which facilitates the reset of the upper pressing plate 2041. The anti-slip component 2043 enhances the stability of the upper pressing plate 2041 when it is pressed and fixed to the safety net.

[0030] In one embodiment of the present invention, Figure 3 As shown, the pushing mechanism 205 includes a base plate 2051 , a clamping shaft 2052 , a limiting slider 2053 , a connecting shaft 2054 and a pressing component 2055 .

[0031] The bottom plate 2051 is movably mounted on the top wall of the upper fixed plate 202, the coupling shaft 2052 is movably mounted on the bottom plate 2051, and the limiting slider 2053 is mounted on the bottom wall of the bottom plate 2051. The limiting slider 2053 is movably mounted within the through slot 206. One end of the connecting shaft 2054 is mounted on the bottom wall of the limiting slider 2053, and a pressing member 2055 is mounted on the other end of the connecting shaft 2054. The pressing member 2055 is abutted against and connected to the upper pressing plate 2041.

[0032] It should be noted that the bottom plate 2051 is limited and slidable in the through slot 206 by means of a limiting slider 2053. During this sliding process, the pressing member 2055 is driven to move by the connecting shaft 2054. As the pressing member 2055 moves, it gradually presses the upper pressing plate 2041 downward, thereby pressing and securing the upper pressing plate 2041 to the safety net. After the safety net is pressed and secured, the engaging shaft 2052 is engaged in the through slot 206 to secure the bottom plate 2051.

[0033] In one embodiment of the present invention, Figure 1 As shown, a blind groove and an open groove are provided on the inner wall of the through groove 206 , the clamping shaft 2052 is clamped in the blind groove, and the connecting shaft 2054 passes through the open groove and is connected to the pressing component 2055 .

[0034] It should be noted that a blind groove and an open groove are provided in the through groove 206 , and the blind groove and the clamping shaft 2052 are clamped and connected, thereby limiting the bottom plate 2051 , and the connecting shaft 2054 passes through the open groove and is connected and moved by the pressing component 2055 .

[0035] Furthermore, the outer diameter of the clamping shaft 2052 is larger than the diameter of the opening slot, so that the clamping shaft 2052 is located at the upper end of the opening slot and does not hinder the movement of the connecting shaft 2054.

[0036] In one embodiment of the present invention, Figure 2 As shown, one end of the upper pressing plate 2041 away from the fixed shaft 10 is provided with a chamfered corner, the bottom wall of the pressing component 2055 is provided with a chamfered corner, and the pressing component 2055 and the upper pressing plate 2041 are tangent.

[0037] The end surfaces of the upper pressing plate 2041 and the pressing component 2055 that are close to each other are respectively provided with chamfered corners, and the chamfered corners are tangent to each other. Then, when the pressing component 2055 moves, the pressing component 2055 abuts against the upper pressing plate 2041, pushing the upper pressing plate 2041 to gradually rotate and fall.

[0038] In one embodiment of the present invention, Figure 2 As shown, the anti-slip component 2043 is a triangular plastic gasket, and the bottom wall of the anti-slip component 2043 is provided with a V-shaped anti-slip pattern.

[0039] It should be noted that the anti-slip component 2043 is a triangular plastic gasket with anti-slip grooves on the surface, which effectively fixes the safety net and prevents it from sliding sideways when the upper pressure plate 2041 is pressed down.

[0040] Specifically, the flame retardancy test of a safety net is performed by clamping the safety net with a fixing clamp. The safety net to be tested is placed between the upper fixing plate 202 and the lower fixing plate 203. The pushing mechanism 205 is then limitedly moved within the through slot 206. The pushing mechanism 205 pushes the base plate 2051 to slide within the through slot 206. The base plate 2051 then drives the pressing member 2055 via the connecting shaft 2054 as it moves. The pressing member 2055 gradually presses the upper pressing plate 2041 downward during the movement, pressing the upper pressing plate 2041 against the safety net. The anti-slip member 2043 at the bottom of the upper pressing plate 2041 engages the lower fixing plate 203. The safety net is clamped and secured, facilitating subsequent flame retardancy testing. Once secured, the connecting shaft 2052 is inserted into the blind slot of the through slot 206 to prevent the base plate 2051 from sliding back.

[0041] In summary, the rotating safety net flame retardant fixed test clamp of the embodiment of the present invention can be easily adjusted according to the area or length of the safety net during testing, and the safety net can be clamped and fixed by pressing and pushing, and the stability of the clamping is ensured, which is convenient to operate and effectively improves the test efficiency.

[0042] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and deform the above embodiments within the scope of the present invention.
