Description

Technical Field

[0001] The utility model relates to a net rope weaving accessory, in particular to a buckling piece and a net rope. Background Art

[0002] During the construction process, in order to ensure the safety of workers and prevent the falling of materials such as concrete and steel bars, anti-fall nets can be used. The anti-fall nets can be fixed around the building, between the steel frame and the floor slab to protect workers in high construction areas, prevent workers, steel bars and concrete from falling from heights, reduce the pollution of the surrounding environment by construction waste, and reduce environmental pollution.

[0003] At present, the net rope is processed into a grid shape through fasteners to form an anti-fall net. Because the net ropes used to manufacture anti-fall nets on the market are of different sizes, it is difficult to use fasteners of the same specification to process the net ropes. Therefore, it is necessary to select corresponding fasteners according to the specific size of the net rope. Moreover, most of the woven anti-fall nets on the market cannot adjust the mesh size. Falling objects that are too small can easily pass through the anti-fall net, increasing safety risks and environmental pollution. Falling objects that are too large occupy a large amount of net ropes of the anti-fall net, which not only increases the investment cost, but also reduces the utilization efficiency of the anti-fall net. Utility Model Content

[0004] The utility model aims to provide a fastening piece and a net rope, and the technical problem to be solved is to break the restriction of the diameter of the net rope on the use range of the fastening piece and expand the application range of the fastening piece.

[0005] The utility model is realized by the following technical solutions:

[0006] A first aspect provides a fastening member, comprising an inner sleeve and an outer sleeve, wherein the inner sleeve is sleeved in the outer sleeve by a thread;

[0007] The inner sleeve is provided with a net rope through hole, and along the axis direction of the net rope through hole, the inner side wall of the inner sleeve gradually extends toward the axis of the net rope through hole, so as to gradually increase the thickness of the side wall of the inner sleeve and gradually reduce the aperture of the net rope through hole;

[0008] Along the axial direction of the net rope through hole, a cutout is arranged on the side wall of the inner sleeve, and the cutout is used to divide the inner sleeve and is communicated with the net rope through hole.

[0009] Since the inner wall of the inner sleeve gradually extends toward the axis of the mesh rope through hole, the aperture of the mesh rope through hole gradually decreases, so the buckle can lock mesh ropes of different diameters; the inner sleeve is divided into multiple parts through the incision, so that the mesh rope can pass through the mesh rope through the hole smoothly; and then the outer sleeve is sleeved on the outside of the inner sleeve through a thread. During the process of rotating the outer sleeve, the incision gradually shrinks, so that the inner wall of the inner sleeve abuts against the mesh rope until the mesh rope is no longer dragged, thereby achieving locking.

[0010] When the length of the net rope needs to be adjusted, the outer sleeve is rotated in the opposite direction, the incision gradually increases, and the locking strength between the inner wall of the inner sleeve and the net rope gradually decreases until the net rope can be dragged. The net rope is dragged to the required length, and then the outer sleeve is rotated to achieve locking. The fastener can not only adapt to net ropes of different diameters and lengths, but also complete the length adjustment of the net rope. Therefore, the fastener breaks the limitation of the diameter of the net rope on the use range of the fastener, expands the application range of the fastener, and can be widely used in various occasions where the net rope needs to be fastened, thereby improving the versatility of the fastener.

[0011] The net rope can be fastened together through simple connection and adjustment, which simplifies the operation process and improves work efficiency.

[0012] Furthermore, a plurality of the above-mentioned net rope through holes are provided, and the axes of the plurality of net rope through holes are parallel to each other.

[0013] By setting up multiple net rope through holes, multiple net ropes can be fastened at the same time, which increases the functionality of the fastening parts; multiple net rope through holes can accommodate multiple net ropes at the same time, so multiple net ropes can be fastened at the same time, which improves the fastening efficiency; the axes of the multiple net rope through holes are parallel to each other, which can ensure the stability of the net rope during the fastening process and prevent the net rope from sliding or loosening.

[0014] In summary, by providing a plurality of mesh rope through holes, the axes of which are parallel to each other, the functionality of the fastening member can be increased, the fastening efficiency can be improved, and the fastening stability can be enhanced.

[0015] Furthermore, the adjacent mesh rope through holes are intersected and connected, and the distances from the same intersection point on the intersecting surface of the adjacent mesh rope through holes to the axes of the two mesh rope through holes in the adjacent mesh rope through holes are equal.

[0016] Adjacent net rope holes intersect and are connected, which can ensure the stability of the net rope during the buckling process and prevent the net rope from sliding or loosening; the distances from the same intersection point on the intersection surface of adjacent net rope holes to the axes of the two net rope holes in the adjacent net rope holes are equal, which can ensure the accuracy of the net rope during the buckling process and make the net rope buckling more accurate.

[0017] Furthermore, the inner wall of the inner sleeve is provided with a first thread.

[0018] By setting a first thread on the inner wall of the inner sleeve, the friction between the inner sleeve and the net rope is increased, the tightness of the fastening piece is improved, and the net rope is prevented from loosening during the fastening process; the presence of the first thread can increase the wear resistance of the fastening piece, making it more durable during use.

[0019] Furthermore, the thread depth of the first thread is less than twice the difference between the radius of the adjacent mesh rope holes and the distance between the two axis lines in the adjacent mesh rope holes.

[0020] Since the thread depth of the first thread is less than twice the difference between the radius of the adjacent mesh rope hole and the distance between the two axis lines in the adjacent mesh rope hole, excessive squeezing of the mesh rope is avoided during the fastening process, and the mesh rope is protected from damage; the appropriate thread depth can ensure the stability of the fastening piece and prevent the mesh rope from sliding or loosening during the fastening process; by precisely controlling the thread depth of the first thread, the structural dimensions of the fastening piece can be optimized to make it more compact and efficient.

[0021] Furthermore, an air bag is arranged on the outer side wall of the outer sleeve.

[0022] The airbag can provide additional cushioning protection. The airbag is coated on the outer sleeve, reducing the probability of abrasions to the human body when contacting the fasteners. When adjusting the length of the net rope, the volume of the airbag is adjusted by inflating or deflating, so as to adjust the length of the net rope to adapt to net ropes of different lengths.

[0023] A second aspect provides a net rope, which is fastened with the above-mentioned fastening pieces to form a grid;

[0024] The net rope comprises a rope body, and a second thread for matching with the first thread is arranged on the surface of the rope body.

[0025] By setting a second thread on the surface of the rope body, it can be matched with the first thread of the inner sleeve, and the first thread and the second thread are clamped to increase the friction between the inner wall of the inner sleeve and the surface of the net rope, and then the outer sleeve and the inner sleeve are connected to achieve the locking of the net rope. In this way, the buckle can be used to conveniently buckle multiple net ropes together to form a stable grid structure.

[0026] In addition, since the surface of the rope body is provided with a second thread, the wear resistance and tensile strength of the rope body can be increased, making the rope body more durable and reliable during use.

[0027] In summary, by providing a second thread on the surface of the net rope, the fasteners can be conveniently fastened to form a grid, thereby improving the stability and durability of the net rope.

[0028] Furthermore, the thread depth of the second thread is the same as the thread depth of the first thread.

[0029] Adjacent mesh rope holes intersect and are connected, and each mesh rope hole passes a mesh rope. After the two mesh ropes passing through the adjacent mesh rope holes are locked, the locking effect is enhanced by the second thread engagement; here, the thread depth of the second thread is prevented from being too deep, which affects the engagement effect of the second thread.

[0030] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0031] Since the inner wall of the inner sleeve gradually extends toward the axis of the mesh rope through hole, the aperture of the mesh rope through hole gradually decreases, so the buckle can lock mesh ropes of different diameters; the inner sleeve is divided into multiple parts through the incision, so that the mesh rope can pass through the mesh rope through the hole smoothly; and then the outer sleeve is sleeved on the outside of the inner sleeve through a thread. During the process of rotating the outer sleeve, the incision gradually shrinks, so that the inner wall of the inner sleeve abuts against the mesh rope until the mesh rope is no longer dragged, thereby achieving locking.

[0032] When the length of the net rope needs to be adjusted, the outer sleeve is rotated in the opposite direction, the incision gradually increases, and the locking strength between the inner wall of the inner sleeve and the net rope gradually decreases until the net rope can be dragged. The net rope is dragged to the required length, and then the outer sleeve is rotated to achieve locking. The fastener can not only adapt to net ropes of different diameters and lengths, but also complete the length adjustment of the net rope. Therefore, the fastener breaks the limitation of the diameter of the net rope on the use range of the fastener, expands the application range of the fastener, and can be widely used in various occasions where the net rope needs to be fastened, thereby improving the versatility of the fastener.

[0033] The net rope can be fastened together through simple connection and adjustment, which simplifies the operation process and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0043] Example 1

[0044] This embodiment 1 provides a fastening member, combined with Figure 1 and Figure 2 , comprising an inner sleeve 10 and an outer sleeve 20, wherein the inner sleeve 10 is sleeved in the outer sleeve 20 by means of threads;

[0045] The inner sleeve 10 is provided with a net rope through hole 11, and the net rope through hole 11 can accommodate two or more net ropes 30. Along the axis direction of the net rope through hole 11, the inner side wall of the inner sleeve 10 gradually extends toward the axis of the net rope through hole 11, so as to gradually increase the thickness of the side wall of the inner sleeve 10 and gradually reduce the aperture of the net rope through hole 11;

[0046] Two or more cutouts 13 are provided on the side wall of the inner sleeve 10 along the axial direction of the mesh rope through hole 11 . The cutouts 13 are used to divide the inner sleeve 10 and are connected to the mesh rope through hole 11 .

[0047] Since the inner wall of the inner sleeve 10 gradually extends toward the axis of the net rope through hole 11, the aperture of the net rope through hole 11 gradually decreases, so the buckle can lock the net ropes 30 of different diameters; the inner sleeve 10 is divided into multiple parts through the incision 13, so that the net rope 30 can smoothly pass through the net rope through the hole 11; and then the outer sleeve 20 is sleeved on the outside of the inner sleeve 10 through a thread. During the rotation of the outer sleeve 20, the incision 13 gradually shrinks, so that the inner wall of the inner sleeve 10 abuts against the net rope 30 until the net rope 30 is no longer dragged, thereby achieving locking.

[0048] When the length of the net rope 30 needs to be adjusted, the outer sleeve 20 is rotated in the opposite direction, the incision 13 gradually increases, and the locking strength between the inner wall of the inner sleeve 10 and the net rope 30 gradually decreases until the net rope 30 can be dragged. The net rope 30 is dragged to the required length, and then the outer sleeve 20 is rotated to achieve locking. The fastener can not only adapt to net ropes 30 of different diameters and lengths, but also complete the length adjustment of the net rope 30. Therefore, the fastener breaks the limitation of the diameter of the net rope 30 on the use range of the fastener, expands the application range of the fastener, and can be widely used in various occasions where the net rope 30 needs to be fastened, thereby improving the versatility of the fastener.

[0049] The mesh rope 30 can be fastened together through simple sleeve connection and adjustment, which simplifies the operation process and improves work efficiency.

[0050] Example 2

[0051] On the basis of Example 1, multiple net rope holes 11 are set, and the axes of the multiple net rope holes 11 are parallel to each other. At this time, the multiple net rope holes 11 are not connected; when two net rope holes 11 are set, combined with Figure 3 Each net rope through-hole 11 is used to pass a net rope 30 , and the net rope passing through two net rope through-holes 11 may be the same net rope 30 after being bent. In the following, the same net rope 30 passing through adjacent net rope through-holes 11 after being bent is referred to as two net ropes 30 passing through adjacent net rope through-holes 11 .

[0052] By setting up multiple net rope through holes 11, multiple net ropes 30 can be fastened at the same time, which increases the functionality of the fastening parts; multiple net rope through holes 11 can accommodate multiple net ropes 30 at the same time, so multiple net ropes 30 can be fastened at the same time, which improves the fastening efficiency; the axes of the multiple net rope through holes 11 are parallel to each other, which can ensure the stability of the net rope 30 during the fastening process and prevent the net rope 30 from sliding or loosening.

[0053] In summary, by providing a plurality of mesh rope through holes 11, the axes of these mesh rope through holes 11 are parallel to each other, which can increase the functionality of the fastening member, improve the fastening efficiency and enhance the fastening stability.

[0054] Example 3

[0055] On the basis of Example 2, the adjacent net rope holes 11 are intersected and connected, and the distances from the same intersection point on the intersection surface of adjacent net rope holes 11 to the axes of two net rope holes 11 in the adjacent net rope holes 11 are equal.

[0056] Adjacent net rope holes 11 intersect and are connected, which can ensure the stability of the net rope 30 during the buckling process and prevent the net rope 30 from sliding or loosening; the distances from the same intersection point on the intersection surface of adjacent net rope holes 11 to the axes of the two net rope holes 11 in the adjacent net rope holes 11 are equal, which can ensure the accuracy of the net rope 30 during the buckling process and make the buckling of the net rope 30 more accurate.

[0057] Example 4

[0058] On the basis of any of the above embodiments, the inner wall of the inner sleeve 10 is provided with a first thread 12, combined with Figure 4 .

[0059] By setting the first thread 12 on the inner wall of the inner sleeve 10, the friction between the inner sleeve 10 and the net rope 30 is increased, the fastening of the fastening piece is improved, and the net rope 30 is prevented from loosening during the fastening process; the presence of the first thread 12 can increase the wear resistance of the fastening piece, making it more durable during use.

[0060] In a specific embodiment, the thread depth of the first thread 12 is less than twice the difference between the radius of the adjacent mesh rope through hole 11 and the distance between the two axes of the adjacent mesh rope through hole 11 .

[0061] Since the thread depth of the first thread 12 is less than twice the difference between the radius of the adjacent mesh rope through hole 11 and the distance between the two axis lines in the adjacent mesh rope through hole 11, excessive squeezing of the mesh rope 30 during the fastening process is avoided, and the mesh rope 30 is protected from damage; the appropriate thread depth can ensure the stability of the fastening piece and prevent the mesh rope 30 from sliding or loosening during the fastening process; by precisely controlling the thread depth of the first thread 12, the structural dimensions of the fastening piece can be optimized to make it more compact and efficient.

[0062] Example 5

[0063] Based on any of the above embodiments, an airbag is provided on the outer side wall of the outer sleeve 20, which is not shown in the figure.

[0064] The airbag can provide additional cushioning protection. The airbag is coated on the outer sleeve 20, reducing the probability of causing abrasions to the human body when contacting the fasteners. When adjusting the length of the net rope 30, the volume of the airbag is adjusted by inflating or deflating, so as to adjust the length of the net rope 30 to adapt to net ropes 30 of different lengths.

[0065] Example 6

[0066] This embodiment 6 provides a net rope, which is fastened by the above-mentioned fastening parts to form a grid;

[0067] The net rope includes a rope body 32, and the surface of the rope body 32 is provided with a second thread 31 for matching with the first thread 12. Figure 5 .

[0068] By setting the second thread 31 on the surface of the rope body 32, it can be matched with the first thread 12 of the inner sleeve 10, and the first thread 12 and the second thread 31 are engaged, increasing the friction between the inner wall of the inner sleeve 10 and the surface of the net rope 30, and then through the sleeve position of the outer sleeve 20 and the inner sleeve 10, the net rope 30 is locked. In this way, the buckle of the net rope 30 can be used to conveniently buckle multiple net ropes 30 together to form a stable grid structure.

[0069] In addition, since the second thread 31 is provided on the surface of the rope body 32, the wear resistance and tensile strength of the rope body 32 can be increased, making it more durable and reliable during use.

[0070] In summary, by providing the second threads 31 on the surface of the net rope 30 , the mesh can be conveniently formed by fastening the fasteners, thereby improving the stability and durability of the net rope 30 .

[0071] In a specific embodiment, the thread depth of the second thread 31 is less than twice the difference between the radius of the adjacent mesh rope through hole 11 and the distance between the two axes of the adjacent mesh rope through hole 11 .

[0072] Adjacent net rope holes 11 intersect and are connected, and each net rope hole 11 passes a net rope 30. After being locked, the two net ropes 30 passing through the adjacent net rope holes 11 are engaged by the second thread 31 to enhance the locking effect; here, the thread depth of the second thread 31 is prevented from being too deep, which affects the engagement effect of the second thread 31.

[0073] The use process of the net rope 30 and the fastening member in the utility model:

[0074] Rotate the outer sleeve 20 to the end of the thinnest side wall of the inner sleeve 10, then pass the net rope 30 through the net rope through hole 11, and after adjusting the net rope 30 to a suitable length, rotate the outer sleeve 20 to move the outer sleeve 20 toward the thicker end of the inner sleeve 10. The first thread 12 on the inner wall of the inner sleeve 10 gradually engages with the second thread 31, and the second thread 31 on the adjacent net rope 30 also gradually engages until the net rope 30 no longer moves relative to the inner sleeve 10, i.e. locking is achieved.

[0075] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
