[0002] A resistance trainer, also known as a resistance trainer, is a type of training equipment primarily designed to increase muscle strength. Users adjust the resistance level to suit their workout needs, thereby boosting metabolism and preventing muscle atrophy. The sled cart in a resistance trainer simulates the pushing and pulling motions of a sled, combined with an adjustable resistance system, providing users with varying training intensities.

[0003] When using a sled push-type resistance trainer, the resistance is adjusted by placing several counterweight iron blocks. The counterweight iron blocks are placed on the columns in a ring shape, and there will be a gap between the iron blocks and the columns. When the user performs pushing and pulling movements, the gap will cause the iron blocks and the columns to constantly collide. This collision will not only cause wear of the iron blocks and the columns, shortening the service life of the trainer, but also interfere with the trainee and affect the user's training effect. Utility Model Content

[0004] The purpose of the utility model is to propose a resistance training device to solve the problem that the iron block used for the counterweight of the existing sled-type resistance training device will collide with the column during the pushing and pulling movement, resulting in a short service life of the training device and affecting the training effect of the user.

[0006] As a further description of the above technical solution: the column assembly includes a fixed column detachably connected to the top of the bracket plate, and the fixed column is provided with a top plate arranged along its length direction through a telescopic slot, and a spring is provided between the top plate and the inner wall of the telescopic slot.

[0007] As a further description of the above technical solution: a gasket is provided on the top plate through the card slot, and the side of the gasket facing the outside of the telescopic slot is on the same vertical plane as the outer side surface of the top plate.

[0008] As a further description of the above technical solution: the bottom of the fixing column is provided with a stud that passes through the bracket plate through the bottom plate, and the stud is provided with a locking nut that abuts against the bottom of the bracket plate.

[0009] As a further description of the above technical solution: a positioning bolt is provided near the top of the connecting sleeve, and a plurality of positioning screw holes that match the positioning bolt are opened on the handle rod along its length direction.

[0010] As a further description of the above technical solution: a threaded end is provided at the bottom of the connecting sleeve, and a threaded sleeve matching the threaded end is provided at the top of the ski board.

[0011] As a further description of the above technical solution: the bracket plate is detachably connected to the ski board via a mounting plate.

[0012] As a further description of the above technical solution: the crossbar is detachably connected to the ski board via a connecting piece.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 5 The present embodiment provides a resistance training device, comprising a support plate 2 located between a pair of sled boards 1, the support plate 2 being detachably connected to the sled boards 1 via a mounting plate 8, an iron block 4 being provided on the support plate 2 via a column assembly 3, a cross bar 5 being provided at the rear end of the sled board 1, the cross bar 5 being detachably connected to the sled board 1 via a connecting piece, and a handle bar 7 being movable along its height direction being provided at the front end of the sled board 1 via a connecting sleeve 6.

[0025] In the present invention, when the user uses the sled cart for resistance training, he selects the corresponding counterweight iron block 4 according to the training needs, and then inserts the iron block 4 into the column assembly 3. The column assembly 3 can prevent the iron block 4 from hitting the column assembly 3 when the sled cart is pushed or pulled, thereby extending the service life of the trainer. After adding the counterweight iron block 4, the user can perform standing push-pull training through the handle bar 7 on the connecting sleeve 6, or perform half-squatting push-pull training through the cross bar 5. The bracket plate 2 is installed between the two sled boards 1 through the mounting plate 8, and the cross bar 5 is detachably connected to the sled board 1 through the connecting piece, which can facilitate the disassembly and maintenance of the trainer.

[0026] Specifically, such as Figure 1-Figure 3 As shown, the column assembly 3 includes a fixed column 31 detachably connected to the top of the bracket plate 2, and a top plate 33 arranged along its length direction is provided on the fixed column 31 through a telescopic slot 32, and a spring 34 is provided between the top plate 33 and the inner wall of the telescopic slot 32, and a gasket 332 is provided on the top plate 33 through a card slot 331, and the side of the gasket 332 facing the outside of the telescopic slot 32 is in the same vertical plane as the outer side surface of the top plate 33.

[0027] Among them, when placing the iron block 4 for counterweight, the annular iron block 4 is passed through the middle hole on the fixed column 31, and the top plate 33 is elastic in the telescopic groove 32 through the spring 34, so that after the iron block 4 is passed through the fixed column 31, the top plate 33 is against the inner wall of the middle hole of the iron block 4, thereby reducing the shaking of the iron block 4 on the fixed column 31, especially during push-pull movements, ensuring that the position of the iron block 4 is relatively stable, avoiding wear caused by the collision between the iron block 4 and the fixed column 31, effectively extending the service life of the entire trainer, and improving the stability and safety of the entire training process.

[0029] Among them, when the fixing column 31 is installed, the stud 36 on the bottom plate 35 of the fixing column 31 passes through the bracket plate 2, and then the locking nut 37 is screwed onto the stud 36. The design of the stud 36 and the locking nut 37 can facilitate the installation and disassembly of the fixing column 31, thereby facilitating the maintenance and inspection of the fixing column 31 and ensuring the safety of the fixing column 31.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, a positioning bolt 61 is provided near the top of the connecting sleeve 6 , and a plurality of positioning screw holes 71 matching with the positioning bolt 61 are provided on the handle bar 7 along its length direction.

[0031] Among them, when the positioning bolt 61 on the connecting sleeve 6 is loosened and disengaged from the positioning screw hole 71, the handle rod 7 can be telescopically moved on the connecting sleeve 6, so that the trainer can be height-adjusted according to usage needs, meeting the training needs of different groups of people and making it more adaptable. After adjusting the position of the handle rod 7, the positioning bolt 61 can be screwed into the positioning screw hole 71 at the corresponding position.

[0032] It should be noted that the bottom of the connecting sleeve 6 is provided with a threaded end 62, and the top of the ski board 1 is provided with a threaded sleeve 11 that mates with the threaded end 62. The threaded end 62 and the threaded sleeve 11 mate with each other, allowing the connecting sleeve 6 and the handlebar 7 to be easily assembled and disassembled from the ski board 1, thereby facilitating timely maintenance and repair in the event of damage, improving maintenance efficiency and reducing repair costs.
