Description

Technical Field

[0001] This utility model relates to the field of barbell training technology, and more specifically, to a barbell training support frame. Background Technology

[0002] In gyms and sports training facilities, barbell training is a basic and important strength training program. During training, the weight of the barbell plates often needs to be changed according to the needs of different trainees. This results in a large number of barbell plates that are temporarily idle. At present, most barbell support racks on the market only focus on the support function of the barbell bar and lack a proper way to store unused barbell plates. This leads to barbell plates being scattered on the ground or piled up messily, which not only takes up training space but also easily creates safety hazards and increases the burden of staff to clean and maintain them.

[0003] In practical use, traditional barbell plates are often stored using simple upright stands or flat placement. This method not only makes the plates prone to tipping over but also causes them to collide with each other, easily damaging their surface. Furthermore, when it is necessary to replace the plates, the lack of a quick fixing and disassembly mechanism requires the operator to expend considerable effort and time to move and replace them. This not only reduces training efficiency but may also lead to sports injuries due to improper operation. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a barbell training support frame to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a barbell training support frame, including a gantry frame, with a diagonal support frame installed on one side of the gantry frame. A fixing mechanism is provided on the diagonal support frame, the fixing mechanism including a support rod, a spiral strip, a fixing plate, a mating groove, a sliding rod, a connecting block, a top rod, a fixing sleeve, and a limiting mechanism. The support rod is installed on the outside of the diagonal support frame, the spiral strip is disposed on the outer wall of the support rod, multiple sets of fixing plates are disposed and fitted against the outer wall of the support rod, the mating groove is disposed on the inner side of the multiple sets of fixing plates and engages with the spiral strip, and multiple sets of sliding rods are disposed on the outer side of the multiple sets of fixing plates. On one side, connecting blocks are installed at the top of multiple sets of sliding rods, and top rods are installed at the top of multiple sets of connecting blocks. The fixed sleeve is slidably connected to multiple sets of sliding rods. The limiting mechanism includes a limiting ring, a rotating sleeve, a limiting groove, an elastic sheet, a contact block, and an arc plate. Two sets of limiting rings are installed on the outer wall of the fixed sleeve. The rotating sleeve is located on the outer side of the fixed sleeve. A limiting sleeve is installed on the outer wall of the rotating sleeve. The limiting groove is located on both sides of the rotating sleeve and is slidably connected to the limiting ring. Multiple sets of elastic sheets are installed on the outer wall of the fixed sleeve. Multiple sets of contact blocks are installed on the inner side of the rotating sleeve. Multiple sets of arc plates are installed on the outer side of the limiting sleeve.

[0008] The present invention is further configured such that multiple sets of the mating grooves are adapted to and slidably connected with the spiral strip. Through the precise matching and sliding engagement of the mating grooves and the spiral strip, the fixed plate is ensured to move more smoothly on the support rod. At the same time, the spiral angle design of the spiral strip can provide a good self-locking effect to prevent the fixed plate from accidentally loosening during use.

[0009] The present invention is further configured such that a barbell plate is provided on the outside of the support rod, and the barbell plate is provided in multiple sets for insertion into the fixed rod. This design, through the insertion method between the support rod and the barbell plate, allows the barbell plate to be securely mounted on the support rod, preventing the barbell plate from tipping over or slipping during storage, and also facilitating quick access and replacement.

[0010] The present invention is further provided that a screw sleeve is fixedly installed on the outer wall of the fixed sleeve. By installing the screw sleeve on the outer wall of the fixed sleeve, a convenient manual operation method is provided. The user can adjust the position of the fixed sleeve by rotating the screw sleeve to achieve quick locking or releasing of the barbell plates.

[0011] The present invention is further provided that a return spring is connected between the bottom surface of the multiple sets of connecting blocks and the fixed sleeve. Through the elastic action of the return spring, the connecting block can be automatically pushed back to its original position when the lock is released, ensuring that the top rod can be disengaged from the fixed position in time, thereby improving the operation convenience and reliability of the device.

[0012] The present invention is further configured such that multiple sets of elastic sheets are all installed obliquely on the outside of the fixed sleeve. The oblique installation method increases the deformation space of the elastic sheets, so that they can generate more suitable elastic resistance when in contact with the contact block, providing better operation feedback and positioning effect.

[0013] The present invention is further configured such that the tops of the multiple sets of contact blocks are all arc-shaped. The arc-shaped design makes the contact between the contact block and the elastic sheet smoother, reduces wear between components, makes the operation process smoother, and extends the service life of the device.

[0014] The present invention is further configured such that a support mechanism is provided on the gantry frame, the support mechanism including a positioning rod, a barbell bar, a connecting sleeve, a hook, a sliding column, and a sliding sleeve. Multiple sets of positioning rods are installed on the inner side of the gantry frame, two sets of connecting sleeves are installed on the outer wall of the barbell bar, hooks are installed on the outer walls of the two sets of connecting sleeves and hooked onto the positioning rods, two sets of sliding columns are installed on both sides of the gantry frame, and sliding sleeves are installed on the two sets of connecting sleeves and slidably connected to the two sets of sliding columns. This structural design provides multi-level height adjustment through the cooperation of the positioning rod and hooks, while the cooperation of the sliding column and sliding sleeve provides stable guidance for the lifting and lowering of the barbell, ensuring the safety and reliability of the training process.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a barbell training support frame, which has the following beneficial effects:

[0017] 1. By cleverly cooperating with the fixing mechanism set on the inclined support frame, including the support rod, spiral strip, fixing plate, mating groove, sliding rod, connecting block, top rod and fixing sleeve, the barbell plates are quickly fixed. The sliding cooperation between the mating groove on the inner wall of the fixing plate and the spiral strip on the outer wall of the support rod, combined with the rotation of the fixing sleeve, achieves a stable clamping of the barbell plates. At the same time, the design of the screw sleeve provides a reliable locking function, solving the problem of scattered barbell plates in the existing technology.

[0018] 2. The innovative design of the limiting mechanism, through the coordinated work of the limiting ring, rotating sleeve, limiting groove, elastic plate, contact block and arc plate, transforms rotational motion into a precise positioning effect. The cooperation between the elastic plate and the contact block generates appropriate operating resistance and positioning feedback, while the design of the arc plate makes the contact with the top rod smoother, ensuring the smoothness and reliability of the entire assembly and disassembly process.

[0019] 3. The support mechanism, through the meticulous design of the positioning rod, barbell bar, connecting sleeve, hook, sliding column, and sliding sleeve, not only provides multi-level height adjustment, but also provides stable guidance for barbell movement through the cooperation of the sliding column and sliding sleeve. The cooperation of the hook and positioning rod ensures safe support for the barbell. These innovative designs not only improve the practicality and safety of the training equipment, but also provide a more convenient and efficient solution for the daily management and maintenance of the gym.

[0029] Please see Figures 1-5 A barbell training support frame includes a gantry frame 1, with a diagonal support frame 2 installed on one side of the gantry frame 1. A fixing mechanism is provided on the diagonal support frame 2, including a support rod 3, a spiral strip 4, a fixing plate 5, a mating groove 6, a sliding rod 7, a connecting block 8, a top rod 9, a fixing sleeve 10, and a limiting mechanism. The support rod 3 is installed on the outside of the diagonal support frame 2, the spiral strip 4 is disposed on the outer wall of the support rod 3, the fixing plate 5 has multiple sets that fit against the outer wall of the support rod 3, the mating groove 6 is disposed on the inner side of the multiple sets of fixing plates 5 and engages with the spiral strip 4, the sliding rod 7 has multiple sets that are installed on the outer side of the multiple sets of fixing plates 5, the connecting block 8 is installed at the top of the multiple sets of sliding rods 7, and the top rod 9 is installed on the outer side of the multiple sets of fixing plates 5. At the top of the connecting block 8, the fixed sleeve 10 is slidably connected to multiple sets of sliding rods 7. The limiting mechanism includes a limiting ring 11, a rotating sleeve 12, a limiting groove 13, an elastic sheet 14, a contact block 15, and an arc plate 16. The limiting ring 11 is provided with two sets installed on the outer wall of the fixed sleeve 10. The rotating sleeve 12 is located on the outer side of the fixed sleeve 10. A limiting sleeve 26 is installed on the outer wall of the rotating sleeve 12. The limiting groove 13 is located on both sides of the rotating sleeve 12 and is slidably connected to the limiting ring 11 respectively. Multiple sets of elastic sheets 14 are provided on the outer wall of the fixed sleeve 10. Multiple sets of contact blocks 15 are provided on the inner side of the rotating sleeve 12. Multiple sets of arc plates 16 are provided on the outer side of the limiting sleeve.

[0030] Multiple sets of mating grooves 6 are adapted to and slidably connected with the spiral strip 4. The working principle is to use the spiral structure of the spiral strip 4 and the precise matching of the mating grooves 6. When the support rod 3 rotates, the fixing plate 5 slides along the spiral strip 4 through the mating grooves 6, thereby realizing the up and down movement of the fixing plate 5 and adjusting the fixed height of the barbell plate 17.

[0031] The support rod 3 has a barbell plate 17 on its outer side. The barbell plate 17 has multiple sets that can be inserted into the fixed rod. The principle is that by setting an insertion structure on the outer side of the support rod 3, multiple sets of barbell plates 17 can be stably fitted onto the support rod 3, so as to realize the orderly storage and quick access of the barbell plates 17.

[0032] The outer wall of the fixed sleeve 10 is fixedly installed with a screw sleeve 18. Its working principle is to manually rotate the screw sleeve 18 to drive the fixed sleeve 10 to move on the slide rod 7, thereby adjusting the position of the fixed sleeve 10 and realizing the clamping or releasing of the barbell plate 17.

[0033] Each of the multiple sets of connecting blocks 8 is connected to a reset spring 19 between its bottom surface and the fixed sleeve 10. The principle is to utilize the elastic properties of the reset spring 19 so that when the locking state is released, the reset spring 19 automatically pushes the connecting block 8 and the top rod 9 back to the initial position, ensuring that the device can be quickly reset.

[0034] Multiple sets of elastic plates 14 are installed at an angle on the outside of the fixed sleeve 10. The working principle is to increase the deformation space of the elastic plates 14 by installing them at an angle. When the rotating sleeve 12 rotates, the elastic plates 14 make elastic contact with the contact block 15, providing appropriate operating resistance and positioning effect.

[0035] The tops of multiple sets of contact blocks 15 are all set in an arc shape. The principle is to use the arc shape design to reduce the friction and wear between the contact blocks 15 and the elastic sheet 14, so that the rotation of the rotating sleeve 12 is smoother and provides better tactile feedback.

[0036] In this embodiment, when it is necessary to fix the barbell plates 17, multiple sets of barbell plates 17 are inserted into the outer wall of the support rod 3. Then, the mating grooves 6 provided on the inner walls of multiple sets of fixing plates 5 are slidably connected to the spiral strips 4 on the outer wall of the support rod 3. Then, rotating the screw sleeve 18 drives the fixing sleeve 10 and the multiple sets of fixing plates 5 to rotate, so that the mating grooves 6 slide along the spiral strips 4, and the bottom surface of the fixing sleeve 10 abuts against the outer wall of the barbell plates 17, clamping the multiple sets of barbell plates 17 and completing the fixation of the barbell plates 17. When it is necessary to disassemble, rotating the limiting sleeve 26, the limiting sleeve 26 slides along the limiting ring 11 through the limiting groove 13, and rotating the rotating sleeve At 12 o'clock, the contact block 15 contacts the elastic plate 14, generating a certain resistance and positioning effect. The limiting sleeve 26 drives the multiple sets of arc plates 16 to rotate. When the multiple sets of arc plates 16 move to the top of the multiple sets of top rods 9 respectively, the contact with the top rods 9 is released. Then, the elastic reset of the multiple sets of return springs 19 pushes the connecting block 8 to move outward. The connecting block 8 pushes the top rod 9 to move outward and abut against the inner wall of the arc plate 16. At the same time, the multiple sets of connecting blocks 8 pull the slide rod 7 to move outward. The multiple sets of slide rods 7 pull the fixing plate 5 to move outward, releasing the lock on the outer wall of the support rod 3. Then the fixing sleeve 10 can be removed from the support rod 3, and then the barbell plate 17 can be disassembled.

[0037] Please see Figure 2 As one implementation of the support mechanism: a support mechanism is provided on the gantry frame 1. The support mechanism includes a positioning rod 20, a barbell rod 21, a connecting sleeve 22, a hook 23, a sliding column 24, and a sliding sleeve 25. Multiple sets of positioning rods 20 are installed on the inner side of the gantry frame 1. Two sets of connecting sleeves 22 are installed on the outer wall of the barbell rod 21. The hooks 23 are installed on the outer walls of the two sets of connecting sleeves 22 and hooked onto the positioning rods 20. Two sets of sliding columns 24 are installed on both sides of the gantry frame 1. The sliding sleeves 25 are installed on the two sets of connecting sleeves 22 and are slidably connected to the two sets of sliding columns 24.

[0038] More specifically, hooks 23 are installed on the connecting sleeves 22 at both ends of the barbell bar 21, which can be hung on the positioning rods 20 inside the gantry frame 1 to support the barbell. Multiple sets of positioning rods 20 can support the barbell bar 21 at different heights. Sliding columns 24 are installed on both sides of the gantry frame 1, and sliding sleeves 25 are installed on the connecting sleeves 22 and slidably connected to the sliding columns 24 to provide vertical guidance for the barbell and ensure the stability of the barbell's up and down movement.

[0039] In summary, during use or operation of the overall equipment: when it is necessary to fix the barbell plates 17, multiple sets of barbell plates 17 are inserted into the outer wall of the support rod 3. Then, the mating grooves 6 on the inner walls of the multiple sets of fixing plates 5 are slidably connected to the spiral strips 4 on the outer wall of the support rod 3. Then, rotating the screw sleeve 18 causes the fixing sleeve 10 and the multiple sets of fixing plates 5 to rotate, so that the mating grooves 6 slide along the spiral strips 4, and the bottom surface of the fixing sleeve 10 abuts against the outer wall of the barbell plates 17, clamping the multiple sets of barbell plates 17 and completing the fixation of the barbell plates 17. When disassembly is required, rotating the limiting sleeve 26 causes the limiting sleeve 26 to slide along the limiting ring 11 through the limiting groove 13. When rotating the rotating sleeve 12, the contact block 15 contacts the elastic plate 14, generating a certain resistance and positioning effect. The limiting sleeve 26 drives the multiple sets of arc plates 16 to rotate. When the multiple sets of arc plates 16 move to the top of the multiple sets of top rods 9 respectively, the contact with the top rods 9 is released. Then, the elastic reset of the multiple sets of return springs 19 pushes the connecting block 8 to move outward. The connecting block 8 pushes the top rod 9 to move outward and abut against the inner wall of the arc plate 16. At the same time, the multiple sets of connecting blocks 8 pull the slide rod 7 to move outward. The multiple sets of slide rods 7 pull the fixing plate 5 to move outward, releasing the engagement with the outer wall of the support rod 3. Then the fixing sleeve 10 can be separated from the support rod 3, and then the barbell plate 17 can be disassembled.

[0040] Hooks 23 are installed on the connecting sleeves 22 at both ends of the barbell bar 21, which can be hung on the positioning rods 20 inside the gantry frame 1 to support the barbell. Multiple sets of positioning rods 20 can support the barbell bar 21 at different heights. Sliding columns 24 are installed on both sides of the gantry frame 1, and sliding sleeves 25 are installed on the connecting sleeves 22 and slidably connected to the sliding columns 24 to provide vertical guidance for the barbell and ensure the stability of the barbell's up and down movement.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
