[0027] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.

[0028] Combined with Figures 1 - 3 As shown, the present utility model provides a high-tension traction wheel protection device, which includes a fixed side cover 1 and a side protection component. The fixed side cover 1 is arranged in a fan-shaped structure and is installed at the end face of the traction wheel for protecting the end face of the traction wheel. A shaft hole 101 is provided on the fixed side cover 1, and the fixed side cover 1 is sleeved on the central shaft of the traction wheel through the shaft hole 101, and the central shaft is a fixed and non-rotating central shaft, and then fixed with a nut.

[0029] The side protection component is connected to the fixed side cover 1. When the fixed side cover 1 is connected to the end face of the traction wheel, the side protection component covers the side of the traction wheel to protect the side of the traction wheel. Wire passing grooves 201 corresponding to the traction grooves are provided on both sides of the side protection component, and the cords on the traction wheel are introduced and led out through the wire passing grooves 201 on both sides;

[0030] In this way, a protection grid can be formed between multiple wire passing grooves 201 on the same side, and the cords pass through the inside of the protection grid. The side of the traction wheel is protected by the protection grid, preventing hands or foreign objects from being brought into the high-speed rotating traction wheel by the cords, reducing the risk of entrainment, and improving safety.

[0031] Combined with Figure 2As shown in the figure, the side protection component is composed of multiple protection plates 2. The multiple protection plates 2 are detachably connected to each other through connecting components. Wire grooves 201 are provided at both ends of the protection plate 2. According to the number of traction grooves of the traction wheel, the corresponding number of protection plates 2 are connected to each other to form a whole, which is covered outside the traction wheel to improve the flexibility of use. When replacing the cord of the traction wheel, by removing the protection plate 2 to expose the side of the traction wheel, the new cord can be wound, and it is not necessary to disassemble the whole protection device, which improves the convenience during wire replacement.

[0032] The protection plate 2 is set to an arc structure corresponding to the fixed side cover 1, so that the protection plate 2 can fit and extend along the side of the traction wheel, improving the protection effect on the side of the traction wheel.

[0033] Furthermore, a plurality of rolling balls 22 are provided at both ends of the protection plate 2, and the rolling balls 22 are distributed on both sides of the wire groove 201. If a person's hand is dragged to the wire groove 201 and squeezed by the cord on the protection plate 2, the person will instinctively pull the hand to one side. At this time, the rolling balls 22 come into contact with the hand, which can convert sliding friction into rolling friction, reduce the resistance of the person's hand to pull away, and enable the person's hand to quickly pull away.

[0034] In a specific embodiment, hemispherical grooves corresponding to the rolling balls 22 are provided on the protection plate 2, and the rolling balls 22 roll in the hemispherical grooves.

[0035] In an alternative embodiment, the thickness of the fixed side cover 1 and the protection plate 2 is 3.0 - 5.0 mm, and preferably the thickness of the fixed side cover 1 and the protection plate 2 is 5.0 mm, so that the fixed side cover 1 and the protection plate 2 have higher strength and meet the protection requirements.

[0036] Combined Figure 2 As shown in the figure, the connecting component includes a connecting plug rod 21 and a second connecting jack 202. Two mutually parallel connecting plug rods 21 are fixed on one side surface of the protection plate 2, and a second connecting jack 202 corresponding to the connecting plug rod 21 is provided on the other side surface of the protection plate 2. The connecting plug rod 21 on the protection plate 2 is inserted into the second connecting jack 202 on the adjacent protection plate 2, which can connect two adjacent protection plates 2 to each other.

[0037] Furthermore, the second connecting jack 202 is configured such that when the connecting plug rod 21 is inserted into the second connecting jack 202, the connecting plug rod 21 is locked in the second connecting jack 202 to prevent the protection plate 2 from falling off due to the high-speed rotation and vibration of the traction wheel.

[0038] In a specific embodiment, a magnet is provided on the end face inside the second connection jack 202, and the connection plug rod 21 is made of a magnetically attractive material. When the connection plug rod 21 is inserted into the second connection jack 202, the end face of the connection plug rod 21 is magnetically attracted to the magnet inside the second connection jack 202, and the connection plug rod 21 is locked in the second connection jack 202 by the magnetic attraction force. When disassembling, a person can pull out the connection plug rod 21 from the second connection jack 202 with a pulling force greater than the magnetic attraction force.

[0039] In an alternative embodiment, the length of the connection plug rod 21 is 2.0 - 3.0 cm, and the length of the second connection jack 202 is the same as that of the connection plug rod 21. Since the length of the connection plug rod 21 is 3.0 cm, the connection plug rod 21 and the second connection jack 202 have a sufficient connection distance to ensure the stability of the connection.

[0040] Combined with Figure 1 As shown, the arc length included angle between the fixed side cover 1 and the protective plate 2 is ≥90°, which can cover and protect the traction wheel in a large range and improve safety.

[0041] Combined with Figure 2 As shown, two first connection jacks 102 are provided on the end faces of the fixed side cover 1 corresponding to the protective plate 2, and the connection plug rod 21 is inserted into the first connection jacks 102, so that the protective plate 2 is connected to the fixed side cover 1.

[0042] Furthermore, the first connection jack 102 is configured such that when the connection plug rod 21 is inserted into the first connection jack 102, the connection plug rod 21 is locked in the first connection jack 102 to prevent the protective plate 2 connected to the fixed side cover 1 from falling off due to vibration when the traction wheel rotates at high speed.

[0043] In a specific embodiment, a magnet is provided on the end face inside the first connection jack 102, and the connection plug rod 21 is made of a magnetically attractive material. When the connection plug rod 21 is inserted into the first connection jack 102, the end face of the connection plug rod 21 is magnetically attracted to the magnet inside the first connection jack 102, and the connection plug rod 21 is locked in the first connection jack 102 by the magnetic attraction force. When disassembling, a person can pull out the connection plug rod 21 from the first connection jack 102 with a pulling force greater than the magnetic attraction force.

[0044] Combined with the above embodiments, by providing the fixed side cover 1 and the side protection component to protect the end face and side of the traction wheel, a wire passing groove 201 is provided on the side protection component, and the cord on the traction wheel is introduced and led out through the wire passing grooves 201 on both sides. A protection grid can be formed between multiple wire passing grooves 201 on the same side, and the cord passes through the inside of the protection grid. The side of the traction wheel is protected by the protection grid to prevent hands or foreign objects from being brought into the high-speed rotating traction wheel by the cord, reducing the risk of entrainment and improving safety;

[0045] The side protection component is composed of multiple protection plates 2. According to the number of traction grooves of the traction wheel, the corresponding number of protection plates 2 are connected to each other to form a whole, which is covered outside the traction wheel to improve the flexibility of use. When replacing the cord of the traction wheel, by removing the protection plate 2 to expose the side of the traction wheel, the new cord can be wound without the need to disassemble the whole protection device, thus improving the convenience during cord replacement.
