However, because the trainer will not step on the middle part in the training stage, the trainer will mostly step on the rear side area of the pedal 20, although the bottom of the base 10 of the existing jumping device is thickened, in practice, the base 10 is in small-area contact with the ground, when the trainer with a large weight steps on the pedal 20 after running, the base 10 is extremely easy to displace, so the invention adds the self-adaptive ground grabbing structure 30 on the basis of the existing jumping device with the spring 21, firstly, the embodiment sets the turnover plate 31 capable of being turned over, the turnover plate 31 can form a plane flush with the base 10 after turning over, so that the contact area between the whole base 10 and the ground is enlarged, the base 10 is not easy to displace, in order to be convenient for the trainer with different weights, the invention further sets the pressure pad 12 on the base 10 on the basis of the turnover plate 31, the pressure of the trainer on the pedal 20 can directly act on the pressure pad 12 through the spring 21, so that the fluid substance in the pressure pad 12 is extruded by the pressure pad 12 in the turnover plate 31, the flexible plate 32 can be tightly applied to the flexible pedal 32, and the weight of the trainer can not be suitable for the weight of the user with a large weight of the user who is not worrying about the weight of the training device when the user is very heavy.
As can be seen from the figure, the extended area of the folded plate 31 after being extended is the position of the rear side of the pedal 20, so that the gravity can be relieved to the point of the exercisers, and the extended expansion plate 32 contacting the ground can also be shot-blasted, so that the stability of the extended area can be improved.
In order to make the sink 11 stably communicate with the inner area of the folding plate 31, two hard tube cavities 33 leading to the outside of the base 10 are connected to two sides of the sink 11, each hard tube cavity 33 is connected to a flexible soft tube cavity 34, and two soft tube cavities 34 are respectively connected to the hollow folding plate 31, so that fluid exchange between the two areas can be realized, wherein the design of the soft tube cavities 34 can facilitate folding operation of the folding plate 31, and the hard tube cavities 33 can provide a certain loading space for the soft tube cavities 34, so that the soft tube cavities 34 are prevented from being excessively bent to be broken.
The folding plate 31 is carried by the whole take-off device and is not required to be used, so that the space occupied by the whole device is small, the folding plate 31 after folding needs to be fixed, specifically, the two folding plates 31 are connected in series through a lock hook when being folded, the lock hook is connected in series with the folding plate 31 in a hooking way, on the outer side wall of the base 10, the folding plate 31 can be fixed through a lock catch, and therefore the edge of the folding plate 31 after folding does not exceed the two edges of the base 10.
In order to let expansion plate 32 have certain restriction distance when flexible in folding plate 31 to avoid it to stretch out by a wide margin and can't reset, expansion plate 32 is in through the setting of the overhanging of a plurality of second high rigidity springs the open end of folding plate 31, folding plate 31's open end is provided with the sealing washer, expansion plate 32 pass through the sealing washer with folding plate 31's open movable fit, in the stage that expansion plate 32 received fluid pressure to pop out, can be tightly held by the high rigidity spring of second, and once the external force disappears after, expansion plate 32 is automatic the reset under the effect of the high rigidity spring of second.
It should be noted that, the first high stiffness spring and the second high stiffness spring have larger stiffness and very small elastic deformation distance, so that the trainer can not feel secondary setback, and the normal use of the tripping device is not affected.
In the stress stage of the pedal 20, the spring 21 is compressed along with the pedal, but if the long-term stress direction is improper or overload is applied, the direction of the spring 21 is possibly deflected, so that the spring 21 is excessively bent when the pedal 20 is stressed, and the foot of a trainer is injured in a direct contact manner.
Specifically, the first induction coil 411 and the second induction coil 421 are both structures of pressure test, that is, are all structures of one coil of induction made of piezoelectric plates, and can perform a relatively complete induction effect no matter in the stressed contact stage or the rebound contact stage of the spring 21.
The upper half of the mounting sleeve 41 needs to be compressed, so that the mounting sleeve 41 cannot be provided with a hard structure, but the lower half of the mounting sleeve 41 needs to be supported strongly, so that the mounting sleeve 41 comprises a hard cylinder 412 fixedly connected with the pressure pad 12, the pedal 20 is pressed against the hard cylinder 412 after being bent to the limit, the top of the hard cylinder 412 is connected with an organ cover cylinder 413, the top of the organ cover cylinder 413 is glued at the lower part of the pedal 20, the first induction coil 411 is arranged in the organ cover cylinder 413, and the organ cover cylinder 413 is connected with the pedal 20 and is of a flexible structure, so that the organ cover cylinder can deflect along with deflection of the pedal 20, and meanwhile, the hard cylinder 412 provides a certain supporting force for the pedal 20, so that the pedal 20 has a certain pad pressing point after being compressed to the limit and is not broken directly.
