It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0020] Embodiment: A sports barbell rack, such as Figure 1-Figure 5 As shown, it includes a base 1, a placement frame 2, a beam 3, a mounting plate 6, a wedge piece 7, a first elastic piece 8 and an unlocking component. The placement frame 2 is fixedly connected to the base 1, the beam 3 is symmetrically fixedly connected to the middle of the left and right sides of the placement frame 2, the top of the beam 3 is symmetrically fixedly connected to the mounting plate 6, the upper part of the mounting plate 6 is slidably connected to the wedge piece 7, the two wedge pieces 7 are symmetrically distributed front to back, and the side where the two wedge pieces 7 are close to each other is an inclined surface, the first elastic piece 8 is fixedly connected between the wedge piece 7 and the mounting plate 6, the first elastic piece 8 is wound around the wedge piece 7, and an unlocking component is provided on the beam 3.
[0021] like Figure 3-Figure 5 As shown, the unlocking assembly includes a wedge block 9, a nitrogen spring 10, a lower pressure frame 11, a lower pressure plate 12 and a limit rod 13. The left and right parts of the wedge piece 7 that are away from each other are fixedly connected with the wedge block 9, and the side of the wedge block 9 close to the wedge piece 7 is an inclined surface. The wedge blocks 9 on the same beam 3 are symmetrically distributed front to back, and the nitrogen springs 10 are fixedly connected to the front and back sides of the top of the beam 3. The nitrogen spring 10 is located between the placement frame 2 and the mounting plate 6. The lower pressure frame 11 is symmetrically slidably connected to the beam 3 front to back, and the inclined surface of the lower pressure frame 11 contacts the inclined surface of the wedge block 9. The piston rod of the nitrogen spring 10 is fixedly connected to the top inside the lower pressure frame 11, and four limit rods 13 are fixedly connected to the base 1. The lower pressure plate 12 is slidably connected between the four limit rods 13, and the top of the lower pressure plate 12 is fixedly connected to the bottom of the four lower pressure frames 11.
[0022] like Figure 2 As shown, it also includes a buffer frame 4 and a second elastic member 5. The buffer frame 4 is slidably connected to the middle of the beam 3. A groove is opened on the top of the buffer frame 4. The buffer frame 4 is located between two mounting plates 6. The second elastic member 5 is fixedly connected between the buffer frame 4 and the beam 3. The second elastic member 5 is wrapped around the buffer frame 4.
[0023] Initially, the barbell 21 is placed in the grooves at the top of the two buffer frames 4, the second elastic member 5 is compressed, the nitrogen spring 10 is in a natural state, the piston rod of the nitrogen spring 10 is in an extended state, the inclined surface of the lower pressure frame 11 is located directly above the inclined surface of the wedge block 9, the lower pressure frame 11 drives the lower pressure plate 12 to be located on the upper part of the limiting rod 13, and the first elastic member 8 is in a natural state, so that the front and rear wedge members 7 are in contact with each other and are located above the barbell 21, thereby limiting the barbell 21.
[0024] When it is necessary to replace the barbell plates of the barbell 21, the barbell 21 can be limited under the action of the wedge-shaped member 7 and the first elastic member 8. It is only necessary to manually remove the barbell plates on the corresponding side in turn and replace them with barbell plates of the required specifications. No manual limiting is required, the operation is simple, time-saving and labor-saving, and it is safe to use.
[0025] When it is necessary to take out the barbell 21 for exercise, the exerciser stands on the lower pressure plate 12, causing the lower pressure plate 12 to slide downward along the limit rod 13, and the lower pressure plate 12 drives the lower pressure frame 11 to move downward, and the piston rod of the nitrogen spring 10 is compressed. Through the contact between the inclined surface of the lower pressure frame 11 and the inclined surface of the wedge block 9, the wedge block 9 is squeezed to move to the side away from each other, and the wedge block 9 drives the wedge member 7 to move to the side away from each other, and the first elastic member 8 is compressed, so that the front and rear wedge members 7 are disengaged, and the bottom of the wedge member 7 is disengaged from the barbell 21, thereby releasing the limit on the barbell 21, and then the exerciser can take out the barbell 21 upward for training, and when the barbell 21 is disengaged from the groove at the top of the buffer frame 4, the buffer frame 4 is driven upward under the elastic force of the second elastic member 5. Move and reset; after the exercise, the barbell 21 is put back into the grooves at the top of the two buffer frames 4, so that the buffer frames 4 move downward, and the second elastic member 5 is compressed, which can effectively buffer the impact force when the barbell 21 falls, and it is safe to use; when the exerciser leaves the lower pressure plate 12, under the elastic force of the nitrogen spring 10, the piston rod of the nitrogen spring 10 extends, driving the lower pressure frame 11 to move upward, and the lower pressure frame 11 drives the lower pressure plate 12 to move upward and reset, and at the same time, the inclined surface of the lower pressure frame 11 is out of contact with the inclined surface of the wedge block 9, and under the elastic force of the first elastic member 8, the wedge member 7 is driven to drive the wedge block 9 to move to the side close to each other until the front and rear wedge members 7 contact each other and are located above the barbell 21, thereby re-limiting the barbell 21 and improving the safety of use.
[0026] like Figure 2 and Figure 6 As shown, it also includes a locker 14, a drawer 15 and a handle 16. The lockers 14 are fixedly connected to the left and right sides of the base 1. The lockers 14 are symmetrically distributed on the left and right sides of the placement rack 2. The drawers 15 are slidably connected to the lockers 14; the handle 16 is fixedly connected to the side of the drawers 15 away from each other.
[0027] The handle 16 is used to control the opening and closing of the drawer 15 to store and retrieve the barbell plates, thereby facilitating the replacement of the barbell plates on the corresponding side of the barbell 21 and ensuring the cleanliness of the barbell plates.
[0028] like Figure 6 As shown, a placement box 17 is also included. The placement box 17 is fixedly connected to the top of the storage cabinet 14. The placement box 17 is provided to facilitate the placement of items to be used, and is convenient to use.
