The buffer elastic member 9 is a spring or an elastic rubber pad.

Described slide bar 6 is a circular tube.

The invention is provided with a foldable base, a chute, a slide bar, a foot pedal with adjustable direction, etc., and satisfies the requirements of people performing splits exercises in various postures.

The base is divided into a first half-plate and a second half-plate, the first half-plate and the second half-plate are hinged and locked together, the first half-plate and the second half-plate have two forms: one is the second half-plate The half of the support board is set up at right angles to the second half of the board. At this time, it is suitable to practice splitting against the wall, as shown in Figure 1, Figure 3, and Figure 4; the second is to lower the first half of the support board and dock with the second half of the Form an integral flat plate, now be suitable for carrying out horizontal chopping or vertical chopping on level ground, when adjusting plate is perpendicular to the length direction with described chute, can carry out horizontal chopping exercise, as Fig. 6, Fig. 7; When adjusting plate and When parallel to the length direction of the chute, vertical chopping exercises can be carried out, as shown in Figure 8 and Figure 9.

Both the first pedal and the second pedal are made with insole-shaped grooves adapted to human feet, and a number of fastening buckles are arranged on both sides of the shoe-shaped grooves for fixing the feet, which are more suitable for putting human feet in. The front end of the first pedal and the rear end of the second pedal are equipped with cushioning elastic parts for buffering the impact force at both ends, reducing wear and noise.

The armrest frame 3 described on each side is a dual-purpose locking armrest frame. The dual-purpose locking armrest frame includes an "L" shaped armrest bar 16 and an insertion bar 17. Arm 16-1 and articulated arm 16-2, the end of articulated arm 16-2 is hinged with described inserting rod 17, and the end of described inserting rod 17 is equipped with telescoping locking bolt 18, and described inserting arm 16- There is a fixed plug 19 at the end of 1, and a positioning slot 20 adapted to the retractable locking pin 18 and the fixed plug 19 is made on the first half-branch 1-1 and the second half-branch 1-2, so The telescopic lock pin 18 is installed in the plunger 17, and the limit slot 18-2 is made on the wall of the plunger 17, and the limit slot 18-2 has an axial guide groove and two different gears. The circumferential limiting transverse groove forms an "F" shape, and the telescopic locking bolt 18 has an adjusting handle 18-1 that protrudes radially and can slide in the limiting slot 18-2.

The first positioning slot 20A of the inserting arm, the second positioning slot 20B of the inserting arm are on the first half support plate 1-1, the first positioning slot 20D of the inserting rod, and the second positioning slot 20C of the inserting rod are on the second On the half-branch 1-2.

As shown in Figure 10, when the first half-support 1-1 is erected and set at right angles to the second half-support 1-2, the hinged arm 16-2 and the insertion rod 17 are vertically aligned. In a straight line, the lower end of the insertion rod 17 is inserted into the first positioning slot 20D of the insertion rod, and the end of the insertion arm 16-1 is inserted into the first positioning slot 20A of the insertion arm. The arm 16-1 is a horizontal support, and the whole is an "L"-shaped locking bracket.

As shown in FIG. 13 , when the first half-board 1-1 is put down and docked with the second half-board 1-2 to form a horizontal flat plate, the hinged arm 16-2 is perpendicular to the insertion rod 17, The lower end of the insertion rod 17 is inserted into the second positioning slot 20C of the insertion rod, and the end of the insertion arm 16-1 is inserted into the second positioning slot 20B of the insertion arm. It is a horizontal support, and the overall shape is grooved or arched to lock the bracket.

The conversion operation of the dual-purpose locking armrest frame is: change the state of Figure 10 to the state of Figure 13 as an example, operate the adjustment handle 18-1, release the locking of the low gear, raise the telescopic locking pin 18 to the high gear, and the telescopic locking pin 18 is disengaged from the first positioning slot 20D of the insertion rod, so that the insertion rod 17 is unlocked, and then the plug of the insertion arm 16-1 is pulled out from the first positioning slot 20A of the insertion arm, and the entire armrest frame is dismantled. After the first half-support plate 1-1 is put down and docked with the second half-support plate 1-2 to form a horizontal flat plate, the end of the insertion arm 16-1 is inserted into the second positioning slot 20B of the insertion arm, Rotate the plunger 17 by 90 degrees to be perpendicular to the hinged arm 16-2, align the lower end of the plunger 17 and insert it into the second positioning slot 20C of the plunger, operate the adjustment handle 18-1, release the lock of the high position, and lower the telescopic When the locking pin 18 reaches the low gear position, the telescopic locking pin 18 is tightly inserted into the second positioning slot 20C of the insertion rod, and the entire armrest frame 3 and the first half-board 1-1 and the second half-board 1-2 are locked, forming a Figure 13 state.

The support length of the insertion rod 17 is equal to the support length of the insertion arm 16-1. The support length refers to: no matter what shape the insertion rod 17 and the insertion arm 16-1 are, and no matter how much the overlapping length of their connecting parts is, the support length refers to when in the situation shown in Figure 13, the insertion The vertical distance from the upper end of the rod 17 and the connecting arm 16-1 to the base 1. The supporting length of the inserting rod 17 is equal to that of the inserting arm 16-1, which is more conducive to the symmetry and stability of the structure. Of course, if the "L" shaped handrail rod 16 is not at a right angle, that is, the angle between the inserting arm 16-1 and the hinged arm 16-2 is greater than or less than 90 degrees, the supporting length of the inserting rod 17 is the same as that of the inserting arm 16. The support lengths of -1 are not equal, and the structure can still realize basic functions. In the state shown in FIG. 13 , the hinged arm 16-2 is in the form of a slash.

The fixed plug 19 at the end of the insertion arm 16-1 is replaced by the telescopic locking bolt 18, and the telescopic locking bolt 18 is installed in the insertion arm 16-1 and made on the wall of the insertion arm 16-1. Limit slot 18-2, limit slot 18-2 has an axial guide groove and two circumferential limit transverse grooves of different gear positions to form an "F" shape, and the telescopic locking bolt 18 has a diameter To the extended adjusting handle 18-1 that can slide in the limit slot 18-2;

The present invention can fix a foot pedal with bolt and pin hole, and the other foot can finish splitting action through the sliding of another pedal, also can two pedals not be fixed, and two feet slide simultaneously in the opposite direction, and this can be according to Personal ability and habits to adjust. In addition, the present invention adds a height-adjustable armrest frame for stabilizing the hands to prevent body or leg injuries caused by unstable center of gravity during the sliding process. The invention takes up little space, is convenient for installation and transportation, has a simple structure, and the operation mode conforms to ergonomics, and is convenient for users to use alone at home.
