Description
Technical Field
[0001] The utility model belongs to the technical field of amusement facilities, and in particular relates to a net rope connector. Background Art
[0002] At present, traditional net rope connectors in similar net rope facilities in the national amusement industry have problems such as inflexible rotation, limited installation position, and poor wear resistance. Children's skin can easily be scratched when they come into contact with them during play, and long-term wear poses a safety hazard.
[0003] In the prior art, a mesh rope connector includes a fixed base and a ball-end fastener. The fixed base has a first stepped cylindrical hole at its center. The first stepped cylindrical hole is composed of, from top to bottom, a first cylindrical hole, a spherical-conical hole, and a second cylindrical hole. The diameter of the first cylindrical hole is smaller than that of the second cylindrical hole. The outer surface of the ball-end fastener is composed of, from top to bottom, a cylindrical surface, a spherical surface, and a conical surface. The cylindrical surface corresponds to the first cylindrical hole, the spherical surface corresponds to the spherical-conical hole, and the center of the ball-end fastener has a second stepped cylindrical hole. This mesh rope connector uses a ball-end structure through which the mesh rope passes. Calculations and tests have shown that it not only meets the strength requirements for securing mesh ropes in multiple scenarios, but also that the spherical structure at the fixed end of the mesh rope has a wider range of motion and a buffering function.
[0004] However, the above-mentioned ball head fastener is made of two hemispherical blocks that are buckled together. During use, the clamping structure between the two hemispherical blocks may break, causing the ball head fastener to cancel the fixation of the net rope. At the same time, the ball head fastener limits the pressure buckle of the net rope, and the stress is concentrated on the net rope, which may cause the net rope to break.
[0005] Therefore, it is urgent to design a net rope connector to solve the above-mentioned problems. Utility Model Content

[0024] Please refer to the attached Figure 1 To the attached Figure 2 The utility model describes a net rope connecting piece.
[0025] At present, traditional net rope connectors in similar net rope facilities in the national amusement industry have problems such as inflexible rotation, limited installation position, and poor wear resistance. Children's skin can easily be scratched when they come into contact with them during play, and long-term wear poses a safety hazard.
[0026] The ball head fastener of the existing net rope connector is made of two hemispherical blocks that are buckled together. During use, the clamping structure between the two hemispherical blocks may break, causing the ball head fastener to cancel the fixation of the net rope. At the same time, the ball head fastener limits the net rope pressure buckle, and the stress is concentrated on the net rope, which may cause the net rope to break.

[0031] Preferably, the diameter of the through hole is smaller than the spherical-conical hole to limit the first direction A of the rotating fastener 2, so that the chain 3 can pass through the through hole, and at the same time limit the first direction A end of the rotating fastener 2 in the spherical-conical hole, and the rotating fastener 2 cannot move toward the first direction A end.
[0032] The chain 3 includes a plurality of chain links, and adjacent chain links are vertically arranged and sleeved with each other.
[0033] A first chain groove 21 is provided on the rotating fastener 2. After the chain 3 is inserted into the first chain groove 21, the chain 3 is then fixed. Specifically, a first fixing hole 22 is provided on the rotating fastener 2. The first fixing hole 22 is communicated with the first chain groove 21. After the chain 3 is inserted into the first chain groove 21, the fixing piece is passed through the first fixing hole 22 and the chain link of the chain 3 to fix the chain 3 to the rotating fastener 2.
[0034] Preferably, the first chain groove 21 is cross-shaped, so that it can adapt to chains 3 of different sizes. Chain links of any length can be fixed to the rotating fastener 2, and chain links of any length can pass through the first chain groove 21. In other embodiments of the present invention, the first chain groove 21 can also be other shapes.
[0035] The fixing piece on the first fixing hole 22 is preferably a bolt and a nut. After the chain 3 is inserted into the first chain groove 21, the bolt passes through the first fixing hole 22 and the chain link of the chain 3, and the bolt passes through the first fixing hole 22 at the other end. The nut is then screwed on the bolt to fix the fixing piece to the rotating fastener 2 and the chain 3. In other embodiments of the present invention, other fixing pieces can also be selected as long as the rotating fastener 2 and the chain 3 can be fixed.
[0036] A second chain groove 42 is provided on the rope end connector 4. After the chain 3 is inserted into the second chain groove 42, the chain 3 is then fixed. Specifically, a second fixing hole 41 is provided on the rope end connector 4. The second fixing hole 41 is connected to the second chain groove 42. After the end of the chain 3 away from the first chain groove 21 is inserted into the second chain groove 42, the fixing piece is passed through the second fixing hole 41 and the chain link of the chain 3 to fix the chain 3 to the rope end connector 4.
[0037] Preferably, the second chain groove 42 is cross-shaped, so that it can adapt to chains 3 of different sizes. Chain links of any length can be fixed to the rope end connector 4, and chain links of any length can pass through the second chain groove 42. In other embodiments of the present invention, the second chain groove 42 can also be other shapes.
[0038] The fixing piece on the second fixing hole 41 is preferably a bolt and a nut.
