In some embodiments, referring to fig. 1, the connecting shaft 11 may be located at a lower portion of one side of the body 1, so that the bearing assembly 2 is further engaged with the webbing belt after being assembled with the bearing assembly 2.
In some embodiments, the connecting shaft 11 is a steel shaft.
Optionally, the steel shaft is made of bearing steel. Because the bearing steel has the advantages of high fatigue strength, good wear resistance, high hardness and good rust resistance, when the material of the steel shaft is selected to be the bearing steel, the connecting shaft 11 can be ensured to have the advantages of high fatigue strength, good wear resistance, high hardness and good rust resistance.
In some embodiments, referring to fig. 2, the connecting shaft 11 includes a first sub-shaft 111 and a second sub-shaft 112, and the first sub-shaft 111 and the second sub-shaft 112 are symmetrically disposed on the body 1 along a central axis of the body 1 to facilitate assembly of the connecting shaft 11 with the bearing assembly 2.
It will be appreciated that there is a space between the first sub-axis 111 and the second sub-axis 112.
In some embodiments, the first sub-shaft 111 and the second sub-shaft 112 are both cylindrical shafts, and the first sub-shaft 111 and the second sub-shaft 112 have the same length and material, so that the manufacturing process is facilitated.
Alternatively, the length of the first sub-shaft 111 and the length of the second sub-shaft 112 may both be 9mm.
In some embodiments, referring to fig. 2, the first sub-shaft 111 has a first fixed end 1111 and a first free end 1112, and the cross-sectional area of the first sub-shaft 111 gradually decreases along a direction from the first fixed end 1111 to the first free end 1112, so as to play a role of guiding and facilitate the ring body 221 to be sleeved on the first sub-shaft 111.
In some embodiments, referring to fig. 2, the second sub-shaft 112 has a second fixed end 1121 and a second free end 1122, and the cross-sectional area of the second sub-shaft 112 gradually decreases along a direction from the second fixed end 1121 to the second free end 1122, so as to play a role of guiding, and facilitate the ring body 221 to be sleeved on the second sub-shaft 112 of the first sub-shaft 111.
It can be understood that the first fixing end 1111 and the second fixing end 1121 are both connected to the body 1, and the first free end 1112 and the second free end 1122 are both away from the body 1.
Alternatively, the distance between the end surface of the first free end 1112 and the end surface of the second free end 1122 may be 31cm.
To ensure that the cylinder 21 can be fitted to the first sub-shaft 111 and the second sub-shaft 112, the length of the cylinder 21 is smaller than the distance between the end surface of the first fixing end 1111 and the end surface of the second fixing end 1121.
The bearing assembly 2 is a core component of the guide ring provided by the embodiment of the application, and plays a role in converting sliding friction between the safety belt and the guide ring into rolling friction.
In some embodiments, the length of the barrel 21 may be 40mm.
In some embodiments, similar to the connecting shaft 11, the material of the cylinder 21 may also be bearing steel. Because the bearing steel has the advantages of high fatigue strength, good wear resistance, high hardness and good rust resistance, when the material of the cylinder 21 is selected to be the bearing steel, the connecting shaft 11 can be ensured to have the advantages of high fatigue strength, good wear resistance, high hardness and good rust resistance.
In some embodiments, the surface of the annular slide 211 is smooth to facilitate engagement with the slip ring 22 to reduce friction.
In some embodiments, referring to fig. 1, each slip ring 22 includes a ring body 221 and a ball member 222, an outer wall of the ring body 221 has an annular fixing groove 223, and the ball member 222 is located in the annular fixing groove 223.
The slip ring 22 is connected with the connecting shaft 11 by arranging the ring body 221; by providing the ball 222, a rolling friction force is generated between the ring body 221 and the cylinder 21.
When in use, the ring body 221 is sleeved on the connecting shaft 11 and can rotate on the connecting shaft 11; meanwhile, the annular slide rail 211 of the cylinder 21 is directly opposite to the annular fixing groove 223 of the ring body 221, so that the ball piece 222 is located between the annular slide rail 211 of the cylinder 21 and the annular fixing groove of the ring body 221, and the ball piece 222 can freely roll between the annular slide rail 211 of the cylinder 21 and the annular fixing groove of the ring body 221.
In some embodiments, referring to fig. 1, the ball element 222 includes a fixed part 2221 and a plurality of balls 2222, the plurality of balls 2222 are disposed on the fixed part 2221 at intervals, and the plurality of balls 2222 contact with the inner wall of the annular slide rail 211.
With this arrangement, the plurality of balls 2222 can be uniformly distributed between the annular slide rail 211 of the cylinder 21 and the annular fixing groove of the ring body 221, thereby generating uniform rolling friction force.
It can be appreciated that each of the balls 2222 has the same diameter and material to ensure stability of the plurality of balls 2222 during rolling.
In some embodiments, the width of the ring-shaped sliding rail 211 and the width of the ring-shaped fixing groove 223 are not greater than the diameter of the plurality of balls 2222, and are not less than half of the diameter of the plurality of balls 2222.
If the width of the annular slide rail 211 and the width of the annular fixing groove 223 are set too large, the plurality of balls 2222 cannot be limited, so that a large noise is generated when the plurality of balls 2222 move between the width of the annular slide rail 211 and the annular fixing groove 223; if the width of the annular slide rail 211 and the width of the annular fixing groove 223 are too small, the plurality of balls 2222 cannot be limited, so that the plurality of balls 2222 easily slip from the annular slide rail 211 and the annular fixing groove 223, and the bearing assembly 2 fails.
In some embodiments, the diameter of each ball 2222 can range from 7mm to 25mm.
Alternatively, referring to fig. 2, the number of balls 2222 may be 7. As will be understood by those skilled in the art, when the ball 2222 with smaller inner and outer diameters is selected, the rotating speed is faster, and the rolling friction is smaller, but the ball 2222 has smaller size, so that the number of balls to be arranged is larger, and the cost is higher; conversely, when the balls 2222 having a large inner diameter and a large outer diameter are selected, the rotational speed is low and the rolling friction force is large, but the balls 2222 have a large size, so that the number of balls to be provided is small and the cost is low. Of course, the size and number of the balls 2222 may be set to other values, which are not described herein.
In some embodiments, referring to fig. 1, the fixing member 2221 has a plurality of ring-shaped frame bodies 2223 connected in series, and a plurality of balls 2222 are provided on the ring-shaped frame bodies 2223 in a one-to-one correspondence.

In some embodiments, the machining method of the fixing part 2221 includes a die casting method and a plastic casting method.
In some embodiments, referring to fig. 1, the material of the annular frame 2223 may be a polymer. Since the polymer material is soft and has a certain elasticity, when the material of the ring frame 2223 is set to be polymer, the wear between the ring frame 2223 and the balls 2222 can be reduced, the noise generated when the balls 2222 roll can be reduced, and the failure of the bearing assembly 2 caused by the misalignment of the balls 2222 can be avoided.
Optionally, the polymer includes nylon, phenolic tape, polytetrafluoroethylene, and the like.
Of course, the ring frame 2223 may be made of other soft metal materials besides polymer, as long as the purpose of reducing wear is achieved.
After the ball member 222 is installed in the bearing assembly 2, the fixing member 2221 may be offset in the radial direction, which is called a radial offset amount, due to a gap between the hollow portion of the ring-shaped housing 2223 and the ball 2222; when assembling the ball members 222, it is ensured that the fixing member 2221 does not contact the ring body 221 when the fixing member 2221 reaches the maximum radial offset, so as to maintain the stability of the bearing assembly 2.
Wherein the radial offset is calculated according to the following formula:
