Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1 - Figure 5 As shown, a locking structure anti-falling barbell plate rack comprises a first connecting frame 1 and a second connecting frame 2; a fixing plate 3 is fixedly connected between the first connecting frame 1 and the second connecting frame 2, a connecting plate 4 is fixedly connected to the top of the fixing plate 3, three groups of weight plate brackets 5 are respectively installed on both sides of the connecting plate 4, and a locking mechanism is arranged inside the weight plate bracket 5;
[0024] The locking mechanism comprises a device groove 6, the device groove 6 is provided inside the bell plate bracket 5, a spring 7 and a baffle 8 are arranged inside the device groove 6, one end of the spring 7 is fixedly connected to the baffle 8, the end of the spring 7 away from the baffle 8 is fixedly connected to the inner wall of the device groove 6, the end of the baffle 8 away from the spring 7 is fixedly connected to an inclined block 9, the inclined block 9 is designed in the shape of a "right triangle", and the right angle side of the "right triangle" is located at the end away from the baffle 8;
[0025] During operation, in order to realize the function of fixing the bell piece, the center hole of the bell piece is aligned with the bell piece bracket 5, and the bell piece is pushed in along the outer side of the bell piece bracket 5. When the bell piece contacts the inclined surface of the inclined block 9, the bell piece exerts an extrusion force on the inclined block 9. At this time, the inclined block 9 is forced to move downward, and the downward movement of the inclined block 9 will drive the baffle 8 to move downward. At this time, the baffle 8 squeezes the spring 7, and the spring 7 is deformed and contracts inwardly under the force. As the bell piece continues to move, it eventually breaks away from the extrusion of the inclined block 9 and is between the inclined block 9 and the connecting plate 4. At this time, the spring 7 stops being stressed and the elastic potential energy is released instantly, thereby driving the inclined block 9 to reset through the baffle 8. At this time, the bell piece is blocked by the inclined block 9 when it is reset and cannot be reset, thereby playing the role of fixing the bell piece.
[0026] Further, such as Figure 3 and Figure 4 As shown, a piston 10 is arranged inside the device groove 6, the size of the piston 10 is adapted to the device groove 6, and the piston 10 is slidably connected to the device groove 6, and the end of the piston 10 away from the spring 7 is fixedly connected to a pull plate 11, and the pull plate 11 is adapted to the size of the bell plate bracket 5;
[0027] During operation, the setting of the piston 10 can seal the interior of the device groove 6 to prevent dust and impurities from entering the interior of the device groove 6. At the same time, by opening the piston 10, the situation inside the device groove 6 can be viewed. When the internal device is damaged, it can be checked and repaired in time. The setting of the pull plate 11 can facilitate the user to pull the piston 10.
[0028] Further, such as Figure 1 and Figure 2 As shown, the first connecting frame 1 is equipped with universal wheels 12, and two groups of universal wheels 12 are provided. Both groups of universal wheels 12 are installed at the bottom ends of the first connecting frame 1 and the second connecting frame 2;
[0029] During operation, in order to facilitate the movement of the bell plate rack, universal wheels 12 are installed at the bottom ends of the first connecting frame 1 and the second connecting frame 2, which reduces resistance when the bell plate rack needs to be moved, thereby facilitating the movement of the bell plate rack.
[0030] Further, such as Figure 4 and Figure 5 As shown, a limiting rod 13 is arranged inside the device groove 6, both ends of the limiting rod 13 are fixedly connected to the inner wall of the device groove 6, and the limiting rod 13 passes through the baffle 8;
[0031] During operation, the setting of the limiting rod 13 can limit one end of the baffle 8, making the baffle 8 more stable when moving and avoiding shaking of the baffle 8 when moving.
[0032] Further, such as Figure 4 and Figure 5 As shown, the limiting rods 13 are provided in two groups, and the two groups of limiting rods 13 are symmetrically distributed at both ends of the baffle 8;
[0033] During operation, two groups of limit rods 13 can simultaneously limit the two ends of the baffle 8, so that the two ends of the baffle 8 are evenly stressed when moving, thereby avoiding the baffle 8 from getting stuck when moving and making its movement more stable.
[0034] Further, such as Figure 4 and Figure 5As shown, the end of the baffle 8 away from the inclined block 9 is fixedly connected to a pull rod 14, the end of the pull rod 14 away from the baffle 8 passes through the bell bracket 5 and extends to the outside of the bell bracket 5, and the end of the pull rod 14 passing through the bell bracket 5 is fixedly connected to a pull ring 15;
[0035] During operation, when pulling the baffle 8, it is only necessary to pull the pull rod 14 to drive the baffle 8 to move. When the weight piece needs to be separated from the obstruction of the inclined block 9, the pull rod 14 is pulled, and the pull rod 14 then drives the baffle 8 to move, and the movement of the baffle 8 drives the inclined block 9 to move. At this time, the weight piece can be taken out, and the setting of the pull ring 15 is more in line with ergonomics, and the user's fingers pass through the pull ring 15 to make it more convenient to pull the pull rod 14.
[0036] Working principle: in order to realize the function of fixing the bell piece, align the center hole of the bell piece with the bell piece bracket 5 and push it along the outside of the bell piece bracket 5. When the bell piece contacts the inclined surface of the inclined block 9, the bell piece applies an extrusion force to the inclined block 9. At this time, the inclined block 9 is forced to move downward, and the downward movement of the inclined block 9 will drive the baffle 8 to move downward. At this time, the baffle 8 squeezes the spring 7, and the spring 7 is deformed and contracts inwardly under the force. As the bell piece continues to move, it finally breaks away from the extrusion of the inclined block 9 and is between the inclined block 9 and the connecting plate 4. At this time, the spring 7 is forced to end and the elastic potential energy is released instantly, thereby driving the inclined block 9 to reset through the baffle 8. At this time, the bell piece is blocked by the inclined block 9 when it is reset and cannot be reset, thereby playing the role of fixing the bell piece. The setting of the piston 10 can seal the inside of the device groove 6 to prevent dust and impurities from entering the inside of the device groove 6. At the same time, opening the piston 10 can view the situation inside the device groove 6. When the internal device is damaged, it can be checked and repaired in time at the first time. The setting of the pull plate 11 can be convenient The user pulls the piston 10. In order to facilitate the movement of the bell plate rack, universal wheels 12 are installed at the bottom ends of the first connecting frame 1 and the second connecting frame 2. This reduces resistance when the bell plate rack needs to be moved, thereby facilitating the movement of the bell plate rack. The setting of the limit rod 13 can limit one end of the baffle 8, making the baffle 8 more stable when moving and avoiding shaking of the baffle 8 when moving. The setting of two groups of limit rods 13 can simultaneously limit the two ends of the baffle 8, so that the baffle 8 can be moved at both ends. The force is evenly applied to both ends, thereby preventing the baffle 8 from getting stuck when it moves, making its movement more stable. When pulling the baffle 8, it is only necessary to pull the pull rod 14 to drive the baffle 8 to move. When the bell piece needs to be separated from the obstruction of the inclined block 9, the pull rod 14 is pulled, and the pull rod 14 in turn drives the baffle 8 to move, and the movement of the baffle 8 drives the inclined block 9 to move. At this time, the bell piece can be taken out, and the setting of the pull ring 15 is more in line with ergonomics, and the user's fingers pass through the pull ring 15 to make it more convenient to pull the pull rod 14.
