Description

Technical Field

[0001] This utility model relates to the field of zipline safety equipment technology, specifically to a three-roller zipline. Background Technology

[0002] In the application of zipline safety equipment, the original ziplines lacked rollers and pulleys. Long-term contact and sliding with the steel cables caused wear and tear on both the cables and the ziplines, resulting in a shorter lifespan. If not inspected in time, this could lead to serious consequences. Furthermore, the fixing effect between most zipline equipment and the steel cables is poor, and long-term use can easily lead to loosening, affecting not only the stability of the zipline process but also potentially creating safety hazards.

[0003] Furthermore, existing pulley structures cause significant wear on the steel cables. Under gravity, excessive friction easily forms at the contact points between the tensioned cables and the components, shortening the lifespan of both the cables and the zipline components, and resulting in insufficient smoothness during ziplining. Additionally, many zipline systems lack structures for connecting external safety equipment, limiting their applicability and making it difficult to meet the safety requirements of different usage scenarios. Moreover, the pulley layout fails to achieve multi-directional contact with the zipline to reduce wear, indicating that overall durability and practicality need further improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a three-roller pulley zipline in which the rollers can contact the zipline, thereby reducing the wear of the two components and increasing the service life of the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A three-roller zipline includes a first zipline assembly, a second zipline assembly, a pin, and rollers. The first zipline assembly has a locking block at its lower part, which is integrally formed with the first zipline assembly. The second zipline assembly has a slot that matches the locking block of the first zipline assembly, allowing the locking block to be inserted into the slot to form a fitted body. The first zipline assembly has a through hole through which the pin passes, and a roller is mounted on the pin, rotatably connected to the pin. The first zipline assembly also has a roller groove for holding the roller.

[0007] Preferably, there are three pins, rollers, through holes, and roller grooves, forming three pulley sets that can be used together; two through holes are located on the upper part of the first zipline assembly, and the other is located on the side of the first zipline assembly; two roller grooves are located on the inner side wall of the first zipline assembly, and the other is located on the inner top of the first zipline assembly.

[0008] Preferably, the first zipline assembly has a through fixing hole in the middle, and the second zipline assembly also has a fixing hole of the same size as the fixing hole of the first zipline assembly. The fixing hole passes through the first zipline assembly and the second zipline assembly, and a fixing shaft can be provided in the fixing hole. The first zipline assembly and the second zipline assembly can be fixed together by the fixing shaft.

[0009] Preferably, the lower end of the first zipline assembly is provided with a limiting block, and the lower part of the second zipline assembly is provided with a limiting groove that is used in conjunction with the limiting block of the first zipline assembly.

[0010] Preferably, both the first and second zipline assemblies are provided with a fixing ring at their lower parts, and the fixing ring is elliptical in shape.

[0011] Preferably, the middle part of the first cable assembly is a fixing part, which is a cylindrical arc surface. The upper part of the first cable assembly is a cylindrical arc surface. The external steel cable can be more reliably fixed by the arc surfaces of the first cable assembly and the second cable assembly.

[0012] Preferably, the fixing part is smooth in the middle and has upward-facing grooves on both sides.

[0013] Beneficial effects

[0014] The cable components of this device form a stable and reliable fit, preventing loosening and relative displacement during use and improving overall structural reliability. The curved surface and groove design more reliably secure the steel cable while reducing wear between the cable and components. A well-designed pulley system further reduces friction loss and extends the device's lifespan. The lower fixing structure can be connected to external safety equipment, expanding its applicability. The overall design enhances both the smoothness of the gliding process and the safety of use, better meeting the needs of different scenarios.

[0024] like Figures 1 to 6As shown, a three-roller pulley zipline includes a first zipline assembly 1, a second zipline assembly 2, a pin 3, and rollers 12. The lower part of the first zipline assembly 1 is provided with a locking block 4, which is integrally formed with the first zipline assembly 1. The second zipline assembly 2 is provided with a slot 5 that matches the locking block 4 of the first zipline assembly 1. The locking block 4 of the first zipline assembly 1 can be inserted into the slot 5 of the second zipline assembly 2 to form a mating body.

[0025] The first zipline assembly 1 has a through hole 6, which is a pre-arranged reserved hole. A pin 3 passes through the through hole 6, and a roller 12 is provided on the pin 3. The roller 12 is rotatably connected to the pin 3. A roller groove 7 is provided in the first zipline assembly 1. The roller groove 7 is used to hold the roller 12. The pin 3 is welded and fixed in the through hole 6, that is, the pin 3 is welded and fixed to the first zipline assembly 1.

[0026] Specifically, there are three pins 3, rollers 12, through holes 6, and roller grooves 7, forming three pulley sets that can be used together. Two through holes 6 are located on the upper part of the first cable assembly 1, and the other is located on the side of the first cable assembly 1. Two roller grooves 7 are located on the inner side wall of the first cable assembly 1, and the other is located on the inner top of the first cable assembly 1. By providing rollers 12 in two different directions, the rollers 12 can contact the cable during use, reducing the wear of the first cable assembly 1 and the second cable assembly 2, and increasing the service life of the device.

[0027] Specifically, the first cable assembly 1 has a through fixing hole 8 in the middle, and the second cable assembly 2 also has a fixing hole 8 of the same size as the fixing hole 8 of the first cable assembly 1. The fixing hole 8 passes through the first cable assembly 1 and the second cable assembly 2. A fixing shaft can be installed in the fixing hole 8. The first cable assembly 1 and the second cable assembly 2 can be fixed together by the fixing shaft, reducing the risk of falling off or loosening and increasing the reliability and stability of the device.

[0028] Specifically, the lower end of the first zipline assembly 1 is provided with a limiting block 9, and the lower part of the second zipline assembly 2 is provided with a limiting groove 10 that is used in conjunction with the limiting block of the first zipline assembly 1. Through the limiting block 9 of the first zipline assembly 1 and the limiting groove 10 of the second zipline assembly 2, the first zipline assembly 1 and the second zipline assembly 2 can be more reliably combined together, reducing the risk of loosening between the first zipline assembly 1 and the second zipline assembly 2.

[0029] Specifically, both the first zipline assembly 1 and the second zipline assembly 2 are provided with a fixing ring 11 at the bottom. The fixing ring 11 is elliptical in shape and is used to connect external safety rings or safety ropes and other safety fixing devices, which increases the application scenarios of this device and gives it a better range of applications.

[0030] Specifically, the first cable assembly 1 has a fixing part 13 in the middle, which is a cylindrical arc surface. The upper part of the first cable assembly 1 is also a cylindrical arc surface. The external steel cable can be more reliably fixed through the arc surfaces of the first cable assembly 1 and the second cable assembly 2.

[0031] Specifically, the fixing part 13 is smooth in the middle and has upward grooves on both sides. During the use of this device, the steel cable will be pulled downward first due to gravity. By providing upward grooves on both sides, the wear of the steel cable on the first sliding cable assembly 1 can be reduced during use. At the same time, the smoothness of the use of this device is increased, the reliability of this device is enhanced, and the service life of this device is also increased.

[0032] Installation process

[0033] First, align the locking block 4 at the lower part of the first cable assembly 1 with the locking groove 5 on the second cable assembly 2 and insert it. Then, place the steel cable between the first cable assembly 1 and the second cable assembly 2, and then rotate the first cable assembly 1 to fix the steel cable. At this time, the limiting block 9 at the lower end of the first cable assembly 1 will be inserted into the limiting groove 10 at the lower part of the second cable assembly 2, so that the two form a fitting body and are combined. Then, place the roller 12 in the roller groove 7, and then insert the pin 3 through the through hole 6, so that the roller 12 rotates on the pin 3, and the pin 3 is inserted into the through hole 6. Installation. When in place, the pin 3 is welded and fixed to the first cable assembly 1. Then, the two ends of the pin 3 are ground so that there is no obvious protrusion. At this time, the roller 12 can roll on the pin 3. Since the pin 3 is welded and fixed to the first cable assembly 1, it is not rotated by the rotation of the roller 12, but acts as a fixing rod. Under the action of the pin 3, the roller 12 can rotate in the gap between the roller 12 and the pin 3 after friction with the steel cable. Safety rings or safety ropes can also be externally attached to the elliptical fixing rings 11 at the bottom of the cable assembly 1 and cable assembly 2.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
