DETAILED DESCRIPTION

[0036] The following will be combined with the 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-9 , the present invention provides a technical solution:

[0038] A training device for college sports, comprising a bottom plate 1, a horizontal plate 2 is fixedly arranged at one end of the bottom plate 1, a first oblique mounting plate 3 and a second oblique mounting plate 4 are fixedly arranged on the bottom plate 1, two movably extending extension plates 5 are arranged inside the horizontal plate 2, and the two extension plates 5 are symmetrically arranged;

[0039] This embodiment is a sit-up machine, with a bottom plate 1 and a cross plate 2 serving as the basic support for the entire device. Figure 1As shown, a T-shape is formed between the bottom plate 1 and the cross plate 2, which ensures the stability of the entire basic support. At the same time, two movably extendable extension plates 5 are arranged inside the cross plate 2. The arrangement of the extension plates 5 further ensures the stability of the basic support. During use, the operator can pull out the two extension plates 5 from the inside of the cross plate 2 to increase the contact area of ​​the basic support.

[0040] A lying plate 6 is arranged above the bottom plate 1 through an adjusting component. The lying plate 6 can adjust the angle under the action of the adjusting component. A detachable soft bag component is arranged on the lying plate 6.

[0041] A mounting rod 7 is fixedly and symmetrically arranged at one end of the lying plate 6 close to the first oblique mounting plate 3, and a head plate 8 is clamped on the mounting rod 7 by a buckle;

[0042] The head plate in this embodiment is arranged on a side close to the first inclined mounting plate 3, and is connected to the lying plate 6 through two mounting rods 7. The head plate 8 in this embodiment is clamped on the mounting rod 7 through existing clips. The clips here are devices well known to people in the field and are not disclosed here. Such a clamping device ensures that the head plate 8 can be disassembled separately later.

[0043] A mounting block 9 is fixedly provided at one end of the lying plate 6 away from the mounting rod 7, the mounting block 9 and the plate surface of the lying plate 6 are arranged vertically, leg support rods 10 are symmetrically provided on both sides of the mounting block 9, a mounting rod 11 is fixedly provided on the mounting block 9, presser foot rods 12 are symmetrically provided on both sides of the mounting rod 11, and columnar soft bags 13 are sleeved on the leg support rods 10 and the presser foot rods 12;

[0044] The mounting block 9 in this embodiment is vertically arranged between the lying plate 6. The mounting block 9 may also be wrapped with a soft bag during the specific implementation process to prevent the legs of the personnel from being scratched during training. The presser foot rod 12 and the leg support rod 10 in this embodiment are both arranged on the side close to the second inclined mounting plate 4. The diameter of the cylindrical soft bag 13 on the leg support rod 10 is larger than the diameter of the cylindrical soft bag 13 on the presser foot rod 12. Such an arrangement can ensure the comfort of the legs during training on the one hand, and at the same time can save the material of the soft bag to a certain extent.

[0045] The adjustment assembly includes a first adjustment roller 14 rotatably arranged on the first oblique mounting plate 3, and a second adjustment roller 15 rotatably arranged on the second oblique mounting plate 4, and the first adjustment roller 14 and the second adjustment roller 15 are both loosely and tightly fixed by a locking rod 16;

[0046] The first adjusting roller 14 is fixedly connected to the lying plate 6, and an adjusting block 17 is fixedly provided on one side of the second adjusting roller 15, and a telescopic plate 18 is movably provided inside the adjusting block 17. The telescopic plate 18 and the adjusting block 17 are provided with corresponding fixing holes 19, and the telescopic plate 18 can be telescopically adjusted inside the adjusting block 17 and is fixed by a fixing rod 20. A connecting roller 181 is rotatably provided on the top of the telescopic plate 18, and the connecting roller 181 is fixedly connected to the bottom of the lying plate 6;

[0047] The adjustment component in the present embodiment is set to adjust the angle of the lying plate 6. The first adjusting roller 14 and the second adjusting roller 15 in the present embodiment are both rotatably set. The rotatable setting is for the convenience of subsequent adjustment of the entire device. The first adjusting roller 14 is fixedly connected to the bottom of the lying plate 6, and the second adjusting roller 15 is fixedly connected with an adjusting block 17. A through groove is provided inside the adjusting block 17, and a telescopic plate 18 is movably provided inside the through groove. The contact position between the adjusting block 17 and the second adjusting roller 15 is concave. The concave setting on the adjusting block 17 ensures the contact area between the adjusting block 17 and the second adjusting roller 15. The adjusting block 17 can be fixed on the second adjusting roller 15 by welding or an integral molding mode. A connecting roller 181 is rotatably set on the top of the telescopic plate 18. The connecting roller 181 is fixedly connected to the bottom of the lying plate 6. The telescopic plate 18 can be telescopically adjusted inside the adjusting block 17, so that the angle of the lying plate 6 can be adjusted.

[0048] The angles between the first oblique mounting plate 3 and the second oblique mounting plate 4 and the bottom plate 1 are both 45 degrees, and when the telescopic plate 18 is completely retracted into the adjusting block 17, the lying plate 6 and the bottom plate 1 are parallel to each other;

[0049] Setting the first inclined mounting plate 3 and the second inclined mounting plate 4 to 45 degrees can reduce the difficulty of manufacturing the device and facilitate the machine to select the length of the retractable plate 18. Because the sit-up machine is used with the head placed at the bottom for training, the difficulty of sit-ups can be adjusted by gradually adjusting the height of the feet. Generally, the head will not be adjusted to a position higher than the feet. Therefore, the present device completely retracts the retractable plate 18 into the adjustment block 17 so that the lying plate 6 and the ground are parallel. At this time, the entire device becomes a bench-like function. Here, by calculating the length of the angle, it can be achieved that when the retractable plate 18 is completely retracted into the adjustment block 17, the lying plate 6 and the ground are parallel. This is a technology well known to those skilled in the art and will not be elaborated here.

[0050] The soft bag assembly includes a plurality of transverse grooves 21 formed on the lying plate 6. The transverse grooves 21 are provided in three pieces and are provided at equal intervals. The lying plate 6 is provided with a plurality of threaded holes 601 penetrating the transverse grooves 21.

[0051] A fixed transverse plate 22 is movably provided inside the transverse groove 21. The number of the fixed transverse plates 22 and the transverse groove 21 is the same, and the length of the fixed transverse plates 22 and the transverse groove 21 is the same. The thickness of the fixed transverse plate 22 is the same as the depth of the transverse groove 21. The fixed transverse plate 22 is fixed inside the transverse groove 21 by a threaded rod 23. A soft pad 221 is fixedly provided on the fixed transverse plate 22. The thickness of the soft pad 221 is not less than 30 mm.

[0052] A strip groove 24 is provided at one end of the lying plate 6 close to the presser foot rod 12, a mounting hole 241 is provided inside the strip groove 24, the strip groove 24 and the transverse groove 21 are connected by a through groove 25, a strip plate 26 is provided inside the strip groove 24, and the strip plate 26 is fixed inside the strip groove 24 by a first nut 28.

[0053] The lying board 6 in the present embodiment is provided with three transverse grooves 21, and the three transverse grooves 21 are arranged at equal intervals. The opening of the transverse groove 21 is close to one side of the head plate 8, and the end of the transverse groove 21 is at a certain distance from the mounting block 9, because the upper part of the transverse groove 21 needs to be covered with a soft pad 221 later, and the area close to the mounting block 9 is generally where the legs are raised or bent, and the human body will not touch it, so there is no need to set a soft pad. The bottom of the soft pad 221 is provided with three fixed transverse plates 22 corresponding to the transverse grooves 21, and the length and thickness of the fixed transverse plates 22 are the same as those of the transverse grooves 21. During use, the operator inserts the fixed transverse plates 22 from the opening of the transverse grooves 21 and pushes the fixed transverse plates 22 to the bottom of the transverse grooves 21. Corresponding threaded holes 601 are provided on the fixed transverse plates 22 and the lying board 6. When the fixed transverse plates 22 are inserted into the interior of the transverse grooves 21, the fixed transverse plates 22 are fixed to the interior of the transverse grooves 21 by the threaded rods 23.

[0054] The strip plate 26 is fixedly connected to the soft pad 221 through the reinforcing rib 27, and the reinforcing rib 27 is fixedly connected to the soft pad 221 through the second nut 29. The reinforcing rib 27 is a strip of cloth, and the thickness of the reinforcing rib 27 is not less than 3 mm.

[0055] A strip groove 24 is provided on the lying board 6, and a strip plate 26 is arranged inside the strip groove 24. The strip plate 26 is fixed inside the strip groove 24 by a first nut 28. The strip plate 26 is connected to the surface of the soft pad 221 through a reinforcing rib 27, so that the reinforcing rib 27 can have a certain pulling effect on the soft pad 221. When the angle of the lying board 6 is too large, the trainee lies on the soft pad 221 to try to ensure the stability of the soft pad 221.

[0056] Working principle: During the use of the device, if the trainer finds that there is too much sweat on the soft pad 221, the trainer can remove the threaded rod 23, separate the reinforcing rib 27 and the soft pad 221, pull out the fixed horizontal plate 22 from the inside of the horizontal groove 21, and replace it with a clean soft pad 221 to fix it to the lying plate 6 for use. Similarly, when the soft pad 221 is damaged, it can be replaced with a new soft pad 221 through the same operation, without replacing the entire device;

[0057] During use, the trainee can pull out the extension plate 5 inside the horizontal plate 2, so that the contact area between the horizontal plate 2 and the ground can be increased, making the base more stable;

[0058] During the use, when the trainee needs to adjust the angle of the lying board 6, the angle of the lying board 6 can be adjusted through the adjustment component.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
