[0044] like Figure 1-13The first embodiment of this utility model is shown: a multifunctional ski.

[0045] Includes two bases 1, and the bases 1 are equipped with an automatic centering guide rail 100;

[0046] Folding frame 2, base 1 is hinged to both sides of folding frame 2;

[0047] The skateboard 3 has a pulley assembly underneath and straddles 4 on both sides. The skateboard 3 is secured to the automatic centering guide rails 100 on both sides of the base 1 via the straddles 4, and slides on the upper surface of the base 1. The straddles 4 have grooves, allowing them to be detachably secured to the automatic centering guide rails 100 on both sides of the base 1. In this technology, the skateboard 3 is detachably secured to the automatic centering guide rails 100 on both sides of the base 1 via the grooves on the straddles 4. This securing method allows for disassembly and assembly without any other tools. Specifically, simply prying up one side of the straddle 4 on the skateboard 3 disengages the groove 4 from the automatic centering guide rail 100 to disassemble the skateboard 3. Installation is similar. This quick disassembly and assembly method increases the product's practicality, enabling the skateboard 3 to be quickly assembled and disassembled in any environment, thereby changing the form of exercise using this product.

[0048] The waist-twisting disc 5 is rotatably mounted on the slide plate 3.

[0049] The elastic pull rope 6 is detachably connected to the base 1 and the slide plate 3 at both ends. The elastic pull rope 6 is used to provide resistance and reset the slide plate 3 during its movement.

[0050] In this embodiment, the folding frame 2 is equipped with a body energy counter 200 for recording data during the exercise process. Two bases 1 are arranged opposite each other on both sides of the folding frame 2. By rotating the bases 1, the two bases 1 can be closed together to achieve folding.

[0051] like Figure 12-13As shown, it also includes a support rod 7, with a handle 701 mounted on its upper end. A spring-loaded protrusion buckle 702 is provided at the end of the support rod 7 away from the handle 701. A connection hole 201 is provided on the upper surface of the folding frame 2. A locking area 202 is provided inside the folding frame 2 relative to the connection hole 201. The support rod 7 extends through the connection hole 201 into the locking area 202, which is used to engage the spring-loaded protrusion buckle 702 with the support rod 7. This technology's handrail design is a detachable handrail. In this embodiment, two stainless steel pipes are fixed together as the support rod 7. One end of each stainless steel pipe is designed with a spring-loaded protrusion buckle 702, and the other end has two holes. The connection between the two stainless steel pipes is achieved through a tight fit between the spring-loaded protrusion buckle 702 and the holes. Disassembly is achieved by gently pressing the spring-loaded protrusion buckle 702. The handrail is fixed to the folding frame 2. Its fixing structure is as follows: a spring-loaded protrusion buckle 702 is designed at one end of the stainless steel pipe. A connecting hole 201 is designed on the folding frame 2. The stainless steel pipe is inserted into the folding frame 2 with zero tolerance. During insertion, the spring-loaded protrusion buckles 702 on both sides of the support rod 7 are compressed into the support rod 7 by the pressure of the side wall of the connecting hole 201. When it extends into the locking area 202 at the bottom of the folding frame 2, the spring-loaded protrusion buckle 702 pops out and automatically locks the handrail. In this embodiment, the locking area 202 consists of two "L"-shaped pieces. The support rod 7 is composed of protrusions, with two protrusions facing each other and a gap between them. When one end of the support rod 7 with the spring-loaded protrusion buckle 702 is inserted into the locking area 202, the spring-loaded protrusion buckle 702 is located at the opposite corner of the protrusion. At this time, the locking area 202 does not exert pressure on the spring-loaded protrusion buckle 702, thus restricting the support rod 7 to the folding frame 2. When it is necessary to remove the armrest, simply rotate the stainless steel pipe 90 degrees to make the spring-loaded protrusion buckle 702 move along the side wall of the protrusion and press it into the support rod 7 so that it can be pulled out.

[0052] like Figure 12-13 As shown: The bottom of the folding frame 2 is provided with a hinge groove 203, and the two side walls of the hinge groove 203 are provided with rotating holes 204. The base 1 is provided with a rotating shaft 20 that matches the rotating hole 204. The base 1 rotates on both sides of the folding frame 2 through the cooperation of the rotating shaft 20 and the rotating hole 204. In this embodiment, one side of the base 1 has a connecting part that extends into the hinge groove 203. The rotating shaft 20 is arranged on both sides of the connecting part. This technology designs a lightweight folding structure. Folding structure details: The folding frame 2 serves as the rotating shaft between the two bases 1. The two ends of the base 1 have protruding rotating shafts 20 as axle pins. The folding frame 2 is designed with bushings that cooperate with the axle pins of the base 1 to achieve the folding effect.

[0053] like Figure 4-8As shown: the slide plate 3 has several movable cavities 21 inside, and one side of the slide plate 3 has a side groove that communicates with the movable cavity 21. The movable cavity 21 has a pin 8 that can move up and down. One side of the pin 8 has an exposed handle 801. The upper surface of the base 1 has a lower fixing port 22 that matches the exposed handle 801.

[0054] In this embodiment, the pin 8 is rotatably disposed in the movable cavity 21. By rotating the pin 8, the exposed handle 801 can be locked into the side groove, thereby limiting the displacement of the pin 8.

[0055] like Figure 4-5 As shown: The side groove includes a transverse groove 23 and a longitudinal groove 24. The pin 8 can move up and down along the longitudinal groove 24. The twisting disc 5 is provided with an upper fixing port 502 corresponding to the pin 8. The exposed handle 801 can be rotated and inserted into the transverse groove 23 to lock the pin 8.

[0056] By setting a lower fixing port 22 on the base 1 and an upper fixing port 502 on the waist twisting disc 5, and using the pin 8 on the slide plate 3 to limit the base 1 and the waist twisting disc 5, in this embodiment, the movable cavity 21 is located on opposite sides of the slide plate 3. The pin 8 in the movable cavity 21 near the folding frame 2 can be inserted into the upper fixing port 502 on the side of the waist twisting disc 5 by pushing it upward, so as to limit the waist twisting disc 5; the pin 8 in the movable cavity 21 away from the folding frame 2 can be inserted into the lower fixing port 22 on the base 1 by pushing it downward, so as to limit the slide plate 3. In this way, convenient switching and locking of rotation and sliding can be achieved, which is compatible with leg or waist fitness, while ensuring that only a single function is activated and used, thus increasing the safety of the equipment.

[0057] By designing a lockable and unlockable rotation function on the waist twisting disc 5, users can arbitrarily select the rotational range of the waist twisting disc. When the user is doing waist twisting exercises, the skateboard can be adjusted to four positions according to the user's hip position to fix the hip position for waist twisting exercises.

[0058] like Figure 6 As shown: The upper surface of the slide plate 3 is provided with a first bearing mounting part 302 and a second bearing mounting part 303. The first bearing mounting part 302 is provided with a first thrust bearing 9, and the second bearing mounting part 303 is provided with a deep groove ball bearing 10. The bottom of the twisting disc 5 is provided with a connecting shaft 501. The connecting shaft 501 passes through the deep groove ball bearing 10 and extends to the bottom of the slide plate 3, and its end is connected to a second thrust bearing 11.

[0059] In this embodiment, a twisting disc 5 is designed on the skateboard 3. The turntable of the twisting disc 5 is designed with double thrust bearings to ensure vertical load-bearing function during rotation and deep groove ball bearings to ensure concentric rotation function. The turntable shaft of this design eliminates the isolation frame of the thrust bearing. The advantage is that the entire turntable is covered with steel balls, making the force-bearing area of ​​the entire twisting disc 5 wider, thus making the product have a greater load-bearing capacity and more stable rotation. The thrust bearings stabilize the vertical load-bearing rotation function, and the twisting disc 5 is designed with a deep groove ball bearing 10 in the middle for concentric rotation in the left and right directions. A second thrust bearing 11 is designed at the bottom of the twisting disc 5. The function of this thrust bearing is to ensure that the entire twisting disc 5 does not tilt during rotation, making the swing more stable.

[0060] like Figure 6-10 As shown: The base 1 includes an upper seat 101, and the upper surface of the upper seat 101 is provided with a guide groove 102 and an upper sliding surface 103; In this embodiment, the guide groove 102 is provided on the surface of the upper seat 101 and is designed to penetrate the upper seat 101 to increase the strength of the base 1, and the upper sliding surface 103 is higher than the guide groove 102, and the front pulley 30 and the guide wheel move on the upper sliding surface 103;

[0061] The lower seat 104 is fixedly mounted below the upper seat 101. The lower seat 104 is provided with an inner compartment 105 for storing the elastic pull rope 6. In this embodiment, the outer compartment of the inner compartment 105 protrudes from one side of the lower seat 104, and the other side of the lower seat 104 is provided with the opening of the inner compartment 105.

[0062] The sealing plate 106 and the inner compartment 105 have a sealing groove 107 at the opening. The sealing plate 106 slides in the sealing groove 107 to open or close the inner compartment 105. The sliding method makes it easier to open the inner compartment 105 and has a simple structure that is not easily damaged.

[0063] In this embodiment, the upper seat 101 has a plurality of threaded connecting posts, and the lower seat 104 has threaded holes that correspond to and match the threaded connecting posts. The upper seat 101 and the lower seat 104 are fixed together by threaded connection. At the same time, the lower seat 104 has an anti-slip groove on the outer periphery of the threaded hole, and an anti-slip pad is fixed in the anti-slip groove to increase the stability and aesthetics of the product.

[0064] like Figure 8-11 As shown: Both ends of the elastic pull rope 6 are provided with locking parts, the bottom surface of the slide plate 3 is provided with a slide plate holder 304 for locking the locking parts, and a number of adjusting holders 108 for adjusting the force of the elastic pull rope 6 are arranged in sequence in the inner compartment 105.

[0065] The elastic pull rope 6 in this technology is an open-type installation with three adjustable levels, allowing users to adjust it to their preferred intensity during exercise. Furthermore, when the elastic pull rope 6 becomes fatigued after numerous workouts and needs replacement, it can be easily replaced by simply opening the sealing plate 106. Specifically, in this technology, the base consists of an upper body 101, a lower body 104, and a sealing plate 106. The upper body 101 and lower body 104 are fixed together. The lower body 104 has an inner compartment 105 for storing the elastic pull rope. The sealing plate 106 closes the opening of the inner compartment 105. The inner compartment 105 contains three adjustable retainers 108, with the intensity of the three retainers 108 arranged from high to low. One end of the elastic pull rope 6 is fixed to one of the adjustable retainers 108, and the other... The end extends through the opening 109 on the lower seat 104 and upper seat 101 to the outside, and then is locked onto the skateboard holder 304 under the skateboard 3 to complete the installation and fixation of the elastic cord 6. When it is necessary to adjust the gear, simply cut open the cover plate 106 to expose the inner chamber 105, then remove the locking part of the elastic cord 6 that is locked on one of the adjustment holders 108, and then lock it onto the other adjustment holder 108 to complete the gear adjustment. After the gear adjustment is completed, simply put the cover plate 106 back on. When it is necessary to replace the elastic cord 6, first open the cover plate 106 and remove the locking part that is locked on the adjustment holder 108, then remove the locking part that is locked on the skateboard holder 304, and then pull the elastic cord 6 out of the inner chamber 105. It is very convenient and solves the technical problem that the elastic cord in the existing skis cannot be replaced.

[0066] like Figure 8-11 As shown: Both the upper seat 101 and the lower seat 104 are provided with corresponding openings 109. The openings 109 are used for the elastic pull rope 6 to pass through. The opening 109 is provided with a pull rope guide wheel 12. The pull rope guide wheel 12 is provided with a guide groove that matches the elastic pull rope 6. One end of the elastic pull rope 6 is fixed on the adjusting bracket 108, and the other end passes through the pull rope guide wheel 12 and through the opening 109 and is fixed on the slide plate bracket 304. The pull rope guide wheel 8 is fixed at the opening 109 by a pin. The pull rope guide wheel 8 is provided to facilitate the guidance and pulling of the elastic pull rope 6.

[0067] In this embodiment, the upper seat 101 is provided with a blocking part on the side near the opening 109. The blocking part is used to abut and restrict the slide plate 3 to prevent the slide plate 3 from falling out.

[0068] like Figure 7-10As shown: The pulley assembly includes several guide wheels installed under the slide plate 3. Each guide wheel includes a guide part 31 and a sliding part 32. When the slide plate 3 is installed on the base 1, the guide part 31 is located in the guide groove 102 and one side is attached to the side wall of the guide groove 102. The sliding part 32 is movably disposed on the upper sliding surface 103. In this embodiment, the bottom surface of the slide plate 3 is provided with two sets of pulley brackets and a front pulley bracket. The front pulley 30 is secured to the front pulley bracket by a pin. The guide wheels are disposed at both ends of a transmission rod. The guide wheels are sleeved on the transmission rod by bearings. The transmission rod is secured to the pulley bracket. The bracket fixing method facilitates assembly and disassembly. Normally, the bottom surface of the slide plate 3 is provided with two sets of guide wheels, that is, four guide wheels. In addition, the four guide wheels in this embodiment are all pulley bearings covered with PU soft rubber. The soft rubber bearing design of the wheels reduces noise and achieves silent sliding.

[0069] The automatic centering guide rail 100 of the base 1 is equipped with a rail top surface, rail side surface, and rail edge automatic centering structure. The wheel set design structure on the skateboard consists of a tread, wheel rim root, and wheel rim. The contact surfaces with the rail are all angled and coordinated to achieve the automatic centering effect of no deviation and deviation correction.

[0070] Additionally, a limiting groove is provided on the base 1, and a skateboard guide wheel 300 is installed on the bottom of the skateboard 3 by means of bolts. When the skateboard 3 is locked on the base 1, the skateboard guide wheel 300 is located in the limiting groove of the base 1, and the skateboard guide wheel 300 moves in close contact with the groove wall of the limiting groove. Since the ski is for fitness, the speed of the skateboard 3 is not fast during the sliding process, and the automatic centering effect cannot be optimal. Therefore, the front skateboard guide wheel 300 is added.

[0071] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
