Rope connector

Abstract

The utility model discloses a rope connector, which relates to the technical field of rope connectors and comprises a connecting ring, a first thread head is arranged at the end of the upper portion of the connecting ring, a second thread head is arranged at the end of the lower portion of the connecting ring, and after an inner thread cylinder is in threaded connection with the outer wall of the first thread head and the outer wall of the second thread head respectively, the first thread head is connected with the second thread head. Bolts are inserted into mounting grooves, penetrate through screw grooves and then are inserted into bottom cavities to abut against pressing plates to be pressed downwards, the pressing plates descend and then are inserted into cross grooves of annular plates to form insertion limiting, and when internal threaded cylinders rotate due to friction of external force, the cross blocks can be supported by the anti-torsion performance of sliding pipes and fixing rods and cannot rotate, so that the cross blocks cannot rotate, and the inner threaded cylinders are prevented from rotating. Therefore, the annular plate cannot rotate, the inner threaded cylinder cannot rotate, and the potential safety hazard that a notch between the first threaded head and the second threaded head is exposed after the inner threaded cylinder rotates due to external force friction is avoided.

Description

Technical Field

[0001] This utility model relates to the field of rope connector technology, and in particular to a rope connector. Background Technology

[0002] Traditional rope connectors are ring-shaped buckles with slots for passing through connecting rings or other ropes. After passing through the connecting rings or other ropes, threaded teeth are provided on the outer walls of both ends of the slot to seal it. One end of the outer wall is threaded to an internal threaded cylinder through the threaded teeth. By rotating the threaded cylinder, both ends are threaded to the threaded teeth, thereby achieving the effect of sealing the slot.

[0003] In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been adequately addressed: In order to facilitate the rotation of the threaded cylinder, its outer wall is polygonal or contains anti-slip teeth or anti-slip grooves. However, during use, the through-ring buckle will wobble, causing friction between it and the rope passing through it. This friction will cause the threaded cylinder to rotate, thus exposing the closed groove. Once the groove is exposed, the through-ring rope can easily come out of the groove, posing a significant safety hazard. Utility Model Content

[0004] The main objective of this invention is to provide a rope connector that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rope connector includes a connecting ring, with a threaded head one at the upper end and a threaded head two at the lower end. An internally threaded cylinder is disposed between the threaded head one and the threaded head two. The top end of the inner wall of the internally threaded cylinder is threaded to the threaded head one, and the bottom end of the inner wall of the internally threaded cylinder is threaded to the threaded head two. An annular plate is fixed to the inner wall of the internally threaded cylinder below the threaded head one, and a cross groove is carved into the annular plate. A mounting groove is carved into the top of the connecting ring at the threaded head one position, and the connecting ring is located at the bottom of the mounting groove. A threaded groove is chiseled between the threaded head and the mounting groove. A bolt is inserted into the mounting groove, and the bottom of the bolt is threaded through the groove. A bottom cavity is chiseled at the bottom of the connecting ring located in the threaded groove. A pressure plate is provided at the bottom of the bottom of the cavity. A cross block is fixed at the bottom of the pressure plate. Several sliding tubes are fixed at the top of the cross block. A fixed rod is inserted and slidably inserted at the top of each sliding tube. A slot is chiseled on the side wall above the bolt in the mounting groove. A rod is inserted into the outer end of the slot. A spring is fixed to the inner end of the slot.

[0007] Preferably, one end of the bolt passes through the slot and is inserted into the interior of the bottom cavity, and the bottom of the end inserted into the bottom cavity contacts the top of the pressure plate.

[0008] Preferably, the outer dimension of the cross block is smaller than the inner dimension of the cross groove.

[0009] Preferably, the top of the fixing rod is fixed to the inner top of the bottom cavity.

[0010] Preferably, a plurality of springs are fixed to the top of the bottom cavity, and the bottom of each spring is fixed to the top of the pressure plate.

[0011] Preferably, the end of the spring that is close to the insertion rod is fixed, and the end of the insertion rod that is away from the spring extends to the outside of the slot and is located above the bolt.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. After the internal threaded cylinder is threaded to the outer walls of thread head one and thread head two respectively, the bolt is inserted into the mounting groove, passes through the thread groove, and is inserted into the bottom cavity to press down against the pressure plate. After the pressure plate descends, it is inserted into the cross groove of the annular plate and forms a penetration limit. When the internal threaded cylinder rotates due to friction from external forces, the torsional resistance of the slide tube and the fixed rod can support the cross block and prevent it from rotating, so that the annular plate cannot rotate, and thus the internal threaded cylinder cannot rotate. This avoids the safety hazard of the groove between thread head one and thread head two being exposed after the internal threaded cylinder rotates due to friction from external forces.

[0014] 2. When the bolt is pressed against the pressure plate and descends, its head will be located deep in the mounting groove, and the insert rod in the slot can be pushed out by the tension of the spring, with one end located above the bolt head. When vibration or shaking occurs, the insert rod can block the bolt and prevent the bolt from stripping due to vibration or shaking. It is suitable for connections that are not frequently opened.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5 As shown, a rope connector includes a connecting ring 1. A threaded head 101 is provided at the upper end of the connecting ring 1, and a threaded head 102 is provided at the lower end of the connecting ring 1. An internal threaded cylinder 4 is disposed between the threaded head 101 and the threaded head 102. The top end of the inner wall of the internal threaded cylinder 4 is threadedly connected to the threaded head 101, and the bottom end of the inner wall of the internal threaded cylinder 4 is threadedly connected to the threaded head 102. An annular plate 41 is fixed to the inner wall of the internal threaded cylinder 4 below the threaded head 101. A cross groove 42 is carved on the annular plate 41. A mounting groove 11 is carved on the top of the connecting ring 1 at the position of the threaded head 101. The connecting ring 1 is located within the mounting groove 11. A threaded groove 13 is chiseled between the bottom and the threaded head 101. A bolt 5 is inserted into the inside of the mounting groove 11. The bottom of the bolt 5 passes through the threaded groove 13 and is threadedly connected. A bottom cavity 14 is chiseled at the bottom of the connecting ring 1 located in the threaded groove 13. A pressure plate 51 is provided at the bottom of the bottom of the bottom cavity 14. A cross block 52 is fixed at the bottom of the pressure plate 51. Several sliding tubes 53 are fixed at the top of the cross block 52. A fixed rod 54 is inserted and slidably inserted at the top of each sliding tube 53. A slot 12 is chiseled on the side wall above the bolt 5 inside the mounting groove 11. A rod 3 is inserted at the outer end of the slot 12. A spring 2 is fixed at the inner end of the slot 12.

[0023] Specifically, one end of the bolt 5 passes through the slot 12 and is inserted into the interior of the bottom cavity 14, and the bottom of the end of the bolt 5 inserted into the bottom cavity 14 contacts the top of the pressure plate 51, so as to press against the pressure plate 51 and drive it to descend.

[0024] Specifically, the outer dimensions of the cross block 52 are smaller than the inner dimensions of the cross groove 42, making it easier for the cross block 52 to be inserted into the cross groove 42.

[0025] Specifically, the top of the fixing rod 54 is fixed to the inner top of the bottom cavity 14, so that the descent of the pressure plate 51 is vertical, and the cross block 52 has an anti-torsion effect after being inserted into the cross groove 42.

[0026] Specifically, several springs 55 are fixed to the top of the bottom cavity 14. The bottom of each spring 55 is fixed to the top of the pressure plate 51. When the bolt 5 rotates and rises, the springs 55 can lift the pressure plate 51.

[0027] Specifically, the end of spring 2 that is close to the insertion rod 3 is fixed, and the end of insertion rod 3 that is away from spring 2 extends to the outside of slot 12 and is located above bolt 5, which can prevent bolt 5 from coming loose.

[0028] Working principle: After the internal threaded cylinder 4 is threadedly connected to the outer walls of thread head 101 and thread head 102 respectively, the bolt 5 is inserted into the mounting groove 11, passes through the thread groove 13, and is inserted into the bottom cavity 14 to press down against the pressure plate 51. After the pressure plate 51 descends, it is inserted into the cross groove 42 of the annular plate 41 and forms a penetration limit. When the internal threaded cylinder 4 rotates due to friction from external forces, the torsional resistance of the slide tube 53 and the fixing rod 54 can support the cross block 52 and prevent it from rotating, thereby preventing the annular plate 41 from rotating, and thus preventing the internal threaded cylinder 4 from rotating. It cannot rotate, thus avoiding the safety hazard of the groove between thread head 101 and thread head 102 being exposed after the internal thread cylinder 4 rotates due to external friction. When the bolt 5 is lowered against the pressure plate 51, its head will be located deep in the mounting groove 11, and the insert rod 3 in the slot 12 can be pushed out by the tension of the spring 2, with one end located above the head of the bolt 5. When vibration or shaking occurs, the insert rod 3 can block the bolt 5, preventing the bolt 5 from being stripped due to vibration or shaking. It is suitable for connections that are not frequently opened.
