DETAILED DESCRIPTION

[0019] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.

[0020] Example 1: See Figure 1 The present embodiment provides a vertical non-fixed sit-up trainer, comprising a buckle 1 of an integrated structure; a first strap 2 connected to the buckle 1, wherein the first strap 2 is on the same vertical line as the buckle under the action of gravity; a second strap 3 for accommodating the ankle, wherein the second strap 3 is connected to the lower part of the first strap 2, and the two ends of the second strap 3 are connected by a press buckle 4; and a movably connected fixing strap 5, wherein the fixing strap 5 is used to connect the buckle 1 and the fixing medium 6.

[0021] Preferably, in this embodiment, the fixing medium 6 is a horizontal bar. A sponge pad 7 is provided at the connection between the second strap 3 and the press buckle 4 .

[0022] See also Figure 2 The compression buckle 4 includes a bayonet and a base. The bayonet 4.2 cooperates with the base 4.1 in a plug-in manner. A three-pronged tooth 4.2.1 is provided at the front of the bayonet 4.2, and a through hole 4.2.3 is provided at the rear of the bayonet 4.2. A cavity 4.1.1 is provided in the base 4.1, and openings 4.1.2 are provided on the left and right sides of the base 4.1. The three-pronged tooth 4.2.1 is provided with a protrusion 4.2.2 at the front of the two outer protrusions, and the protrusion 4.2.2 is interference-fitted with the openings 4.1.2 on the left and right sides of the base 4.1. The compression buckle 4 can adjust the length of the second strap 3.

[0023] The specific usage is as follows:

[0024] Device installation: The fixing belt 5 is put on the fixing medium 6, and the buckle 1, the first strap 2, and the second strap 3 connected in sequence below the fixing belt 5 are naturally vertical.

[0025] Ankle fixation: The operator places the ankle into the second strap 3, inserts the pin 4.2 of the pressure buckle 4 into the cavity 4.1.1 of the base 4.1, and the projection 4.2.2 on the three-pronged insert 4.2.1 of the pin 4.2 is interference fit with the opening 4.1.2 of the base 4.1 to achieve tightening and limiting. At this time, the length of the rope of the second strap 3 passing through the through hole 4.2.3 of the pin 4.2 can also be adjusted to achieve tightness adjustment of the ankle fixation.

[0026] Unlocking the ankle: Press the protrusions 4.2.2 on both sides of the three-pronged tooth 4.2.1 to release the interference fit between the protrusions and the opening 4.1.2, so that the latch 4.2 is pulled out of the holder 4.1, and the second strap 3 is released from fixing and locking the operator's ankle.

[0027] Embodiment 2:

[0028] Embodiment 1 The buckle of the second binding strap may also have other structural forms.

[0029] like Figure 3 As shown, the press-type buckle in this embodiment includes a lock tongue 8 and a lock seat 8.1, and the lock tongue 8 and the lock seat 8.1 are respectively connected to the two ends of the second strap 3, and the lock tongue 8 includes a lock tongue body 8.2, a spring 8.3 and a limit block 8.4, and the bottom of the limit block 8.4 is connected to the lock tongue body 8.2 through the spring 8.3, and a cavity 8.5 with an opening on one side is provided in the lock seat 8.1, and the cavity 8.5 cooperates with the lock tongue 8, and an opening 8.6 cooperating with the lock tongue limit block 8.4 is provided on one side of the lock seat cavity 8.5.

[0030] Specifically speaking:

[0031] When the lock tongue 8 needs to be inserted, the stopper 8.4 is pressed, and the spring 8.3 is compressed, pushing the lock tongue 8 into the cavity 8.5 of the lock seat 8.1. After the stopper 8.4 enters the cavity 8.5, it will continue to compress the spring 8.3 under the pressure of the inner wall of the cavity. The lock tongue body 8.2 is pushed in continuously until the stopper 8.4 reaches the lock seat opening 8.6. At this time, the stopper 8.4 is inserted into the opening 8.6 to form a limit under the action of the compression force of the spring 8.3. At this time, the lock tongue 8 is limited in the lock seat 8.1 and cannot move, realizing the locking of the press buckle.

[0032] When the lock tongue 8 needs to be pulled out, the limit block 8.4 is pressed, the spring 8.3 is compressed, the limit block 8.4 is pulled out from the opening 8.6 and enters the cavity 8.5, and the limit is released. At this time, the lock tongue 8 can move freely in the cavity 8.5, and the buckle can be unlocked by pulling the lock tongue 8 outward.

[0033] The above operations can all be completed with one hand.

[0034] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
