Description

Technical Field

[0001] The utility model belongs to the field of anti-falling nets, and more specifically, particularly relates to a building safety anti-falling net. Background Art

[0002] An anti-fall net is a protective device that prevents personal injury or life-threatening consequences of falling from heights. It is widely used in high-altitude places such as high-rise buildings and bridges. It can effectively prevent accidents caused by falling from heights and intercept and protect people falling from buildings and pedestrians below the building. At present, the traditional safety anti-fall net is only to directly tie the net rope of nylon or steel wire to the bracket of fixed structure. The bracket vigorously supports and stretches the net rope to form a fall interception area. When the falling object contacts the net rope, its huge falling impact force will directly pull the bracket through the net rope, causing the connection between the bracket and the floor wall to loosen, affecting the stability of the installation part of the anti-fall net and the building body. In addition, in actual construction projects, in order to make the protective net have a better protective effect, the inclination angle of the protective net needs to be determined according to the specific project conditions. Since the bracket is a fixed triangular structure, the support angle of the anti-fall net bracket needs to be pre-customized according to the project conditions. It can be seen that the traditional anti-fall net cannot be adjusted for different building structures and construction environments, and the anti-fall net support structure has poor versatility.

[0022] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figures 1-8 As shown, the utility model provides a building safety anti-fall net, including a mounting frame 4; the top of the mounting frame 4 is hinged with a placement frame 1, the lower side of the placement frame 1 is welded with a guide rod 14, the center position of the front side of the mounting frame 4 is rotatably connected with a threaded rod 11, the top of the threaded rod 11 is installed with a knob 16, and the front side of the mounting frame 4 is welded with a column 6; it also includes a support rod 7 and a guide column 17; the top of the support rod 7 is hinged with a support slider 15, the bottom end of the support rod 7 is hinged with the mounting frame 4, the center part of the support rod 7 is hinged with a push-pull connecting rod 8, and the other end of the push-pull connecting rod 8 is hinged with a lifting plate 5; the bottom end of the guide column 17 is welded with a placement frame 1, the top of the guide column 17 is welded with a top plate 3, and the outer side of the guide column 17 is embedded with a spring 10.

[0024] In the embodiment of the present disclosure, a buffer frame 12 is welded to the top of the spring 10, a grid frame 2 is placed on the upper side of the buffer frame 12, and a placement frame 1 is welded to the bottom end of the spring 10. The elastic deformation characteristics of the spring 10 itself absorb the impact force of falling objects placed on the grid frame 2 on the upper side of the buffer frame 12, thereby reducing the gravity impact of the placement frame 1.

[0025] In the embodiment of the present disclosure, the buffer frame 12 is a rectangular frame structure that passes through from top to bottom. The four corners of the upper side of the frame structure of the buffer frame 12 are provided with threaded through holes and circular through holes. The threaded through holes of the buffer frame 12 are screwed with clamping bolts 9. The inner wall of the circular through hole of the buffer frame 12 is bonded with a rubber sleeve 18. The rubber sleeve 18 is a cylindrical structure that passes through from top to bottom. The inner side of the cylinder of the rubber sleeve 18 is inserted with a guide column 17. The inner wall of the rubber sleeve 18 fits tightly against the outer wall of the guide column 17. The buffer frame 12 slides directionally along the guide column 17 under the support of the spring 10. The rubber material on the inner side of the rubber sleeve 18 increases the friction of the buffer frame 12 moving along the guide column 17 to form a friction damping effect, consume the rebound force of the spring 10, and prevent the buffer frame 12 from vibrating back and forth under the rebound force of the spring 10, so that the falling person inside the net rope 13 can quickly remain stable.

[0026] In the embodiment of the present disclosure, the grid 2 is a frame structure that passes through from top to bottom. A net rope 13 is tied to the inner side of the grid 2. A rectangular convex plate is provided on the outer side of the grid 2 near the top of the frame. The lower side of the convex plate is placed on the upper side of the buffer frame 12. Four groups of through holes are provided on the side of the convex plate of the grid 2 that pass through from top to bottom. The through holes of the grid 2 are opposite to the threaded through holes of the buffer frame 12 up and down. The clamping bolts 9 are inserted into the through holes of the grid 2. When the clamping bolts 9 are screwed downward along the threaded through holes of the buffer frame 12, the nuts of the clamping bolts 9 cooperate with the upper side of the buffer frame 12 to squeeze and clamp the grid 2. The grid 2 is thus completely removed and replaced from the buffer frame 12 by disassembling the clamping bolts 9. This avoids the process of tying and untying the net rope 13 on the grid 2 when the net rope 13 is disassembled and replaced, and the disassembly and assembly operation of the net rope 13 is simpler.

[0027] In the embodiment of the present disclosure, a threaded through hole is provided at the center position of the upper side surface of the lifting plate 5, and the outer side surface of the threaded rod 11 is threadedly engaged with the threaded through hole of the lifting plate 5. The upper side surface of the lifting plate 5 near the left end and the right end is provided with through holes that pass through the upper and lower parts. The two groups of columns 6 are respectively inserted into the through holes of the lifting plate 5. During the rotation of the threaded rod 11, the threaded rod 11 drives the lifting plate 5 to slide upward or downward along the column 6. The lifting plate 5 drives the support rod 7 to perform an up and down flipping movement through the push-pull connecting rod 8 hinged on the front side. The support rod 7 pushes the support slider 15 to support the placement rack 1 to perform synchronous up and down flipping, and arbitrarily change the inclination angle of the grid 2 carried by the placement rack 1.

[0028] In the embodiment of the present disclosure, a through hole running through the front and back is provided at the center position of the support slider 15, the guide rod 14 is inserted into the through hole of the support slider 15, the upper side surface of the support slider 15 is attached to the lower side surface of the placement rack 1, and the support slider 15 slides directionally along the lower side surface of the placement rack 1 under the support of the guide rod 14, so that the support slider 15 stably supports the placement rack 1 to perform angle tilting and flipping operations.

[0029] The specific usage and function of this embodiment are as follows:

[0030] When the utility model is adjusting the inclination angle of the anti-fall net, the knob 16 is manually turned, and the knob 16 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the lifting plate 5 engaged with the outer side surface to move upward or downward along the two sets of columns 6, and the lifting plate 5 drives the push-pull connecting rod 8 hinged on the front side to pitch and flip, and the push-pull connecting rod 8 drives the support rod 7 to flip during the flipping process. At this time, the support rod 7 pushes the support slider 15 hinged on the top to move in a directional manner along the guide rod 14, and the upper side of the support slider 15 squeezes and pushes the placement frame 1 to pitch and flip, and the placement frame 1 drives the buffer frame 12 through the guide column 17. Synchronously flipping, the buffer frame 12 drives the clamping bolts 9 to tighten the clamped grid frame 2 at the threaded through holes of the buffer frame 12 to perform synchronous flipping movement, thereby completing the flexible adjustment of the inclination angle of the grid frame 2. When the falling object contacts and hits the net rope 13 tied to the inner side of the grid frame 2, the net rope 13 pushes the buffer frame 12 to move downward through the grid frame 2, and the rubber sleeve 18 bonded to the inner side of the through hole of the buffer frame 12 moves downward synchronously along the guide column 17. The buffer frame 12 squeezes the spring 10 welded on the lower side, causing the spring 10 to undergo elastic deformation. The spring 10 absorbs the squeezing force of the buffer frame 12, thereby reducing the falling impact of the placement rack 1.

[0031] All of the above components are mounted, connected, or configured using conventional mechanical methods, such as welding, threaded connections, and screw connections. The specific structures, models, and coefficients of all components are proprietary technologies, and any method that can achieve the desired effect may be employed. The clamping bolts 9 used are commonly available commercially and require only connection according to the included instruction manual, so further description is omitted here.

[0032] The technical solutions of the present invention are not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
