Description

Technical Field

[0001] This utility model relates to the field of sports equipment, and more particularly to a support structure and a multifunctional crawler containing the support structure. Background Technology

[0002] A crawler is a device specifically designed to promote fitness, rehabilitation, and exercise. It helps users perform horizontal movement training by mimicking crawling motions, effectively exercising the abdominal, back, and pelvic floor muscles and enhancing core stability. Existing crawlers consist of a frame structure and a sliding platform. Specifically, the stable frame supports the entire device, ensuring sufficient stability and safety during use. The sliding platform on the frame allows users to perform crawling-like movements, exercising their abdominal and back muscles through coordinated hand and foot movements.

[0003] The support structure is the structure on the crawler used to support human body parts. Currently, the structure of the support structure is relatively fixed and cannot be freely switched in a modular way, resulting in a single exercise mode for users. At the same time, it is not convenient and efficient to fix the support structure to the sliding platform of the crawler, which has the disadvantages of low flexibility and expandability. Utility Model Content

[0004] The purpose of this invention is to provide a support structure and a multifunctional crawler incorporating this support structure. By setting a modular, fixable support structure, the support structure offers the advantages of convenient and efficient operation, and supports multiple movement modes. The specific technical solution is as follows:

[0005] A support structure movable on a fitness equipment track includes a support pad, a seat plate, and a locking assembly. The support pad and the seat plate are connected opposite to each other. A receiving portion is formed on the seat plate. The locking assembly is disposed within the receiving portion, and one end of the locking assembly protrudes from the support pad and the seat plate to facilitate manual adjustment of the locking structure within the receiving portion.

[0006] Furthermore, the receiving part includes a dial slot and a pin hole that are interconnected, and the locking assembly includes a pin and a dial that are connected together. The pin is received in the pin hole, and the dial can move in the dial slot to drive the pin to move in the pin hole.

[0007] Furthermore, the accommodating part has a paddle slot located between the edge of the seat plate and the edge of the support pad. When the paddle is located in the paddle slot, the end of the paddle away from the pin protrudes from the edge of the seat plate and the edge of the support pad.

[0008] Furthermore, the pin and the lever are perpendicular to each other, and the cross-section of the pin has an inverted L-shaped structure.

[0009] Furthermore, a positioning groove is formed on the pin, and a positioning component is provided on the base plate. When the pin in the pin hole is opposite to the positioning component, the positioning component can abut against the positioning groove to limit the pin.

[0010] Furthermore, the positioning component includes a ball, a spring, and a stud. The ball is disposed at one end of the stud near the pin, and the spring is disposed at the other end. The positioning groove includes at least one of a first groove and a second groove. When the pin moves in the pin hole, the spring abuts against the ball so that when the ball is opposite to the first groove or the second groove, the ball can be pushed into the first groove or the second groove by the spring.

[0011] Furthermore, a mating concave-convex structure is provided between the top surface of the seat plate and the bottom surface of the support pad to facilitate the mounting and dismounting of the support pad and the seat plate.

[0012] Furthermore, the support pad is fixedly connected to the seat plate in the first direction, and the support pad and the seat plate are movably connected in the second direction. The first direction and the second direction are different to switch between different exercise modes.

[0013] Furthermore, the support pad includes a base area and an extension area. The base area can be arranged opposite to the seat plate, and the extension area has through-holes. Alternatively, the length of the support pad is not greater than the length of the seat plate. Alternatively, the third support pad is made of a soft material.

[0014] Furthermore, it also includes an armrest, a first extension is provided on the side of the seat plate facing the direction of track extension, and the armrest is detachably connected to the first extension; and / or, it also includes a lower limb support, a second extension is provided on the side of the seat plate facing the direction perpendicular to the direction of track extension, and the lower limb support is detachably connected to the second extension.

[0015] Furthermore, the armrest is a curved rod-shaped structure with an obtuse angle, including an extension rod and a handle connected together, and the free end of the extension rod is connected to the first extension part through a snap-fit ​​structure.

[0016] Furthermore, the lower limb support includes a fixed post and a support post arranged opposite to each other, and a connecting arm connecting the fixed post and the support post. The fixed post is connected to the second extension part through a snap-fit ​​structure so that the support post is located above the support structure.

[0017] Furthermore, a second fixing ring is provided on the base plate of the support structure.

[0018] A multi-functional crawler includes the support structure described above.

[0019] The support structure of this utility model and the multifunctional crawler containing the support structure have the following advantages:

[0020] 1. The locking component and the receiving part of the seat plate, as well as the support pad, cooperate with each other, so that one end of the locking component protrudes from the support pad and the seat plate, which makes the locking component convenient and efficient to operate, without affecting the replacement of the support pad.

[0021] 2. The support pad is connected to the seat plate through a snap-fit ​​structure, which restricts the horizontal movement of the support pad on the seat plate and allows for quick replacement of the support pad without the need for tools, making it easy to disassemble and assemble.

[0022] 3. The locking component is positioned by setting a positioning groove on the pin, which makes the operation more convenient for users, enhances the user's perception during operation, and improves the user experience.

[0023] 4. The support structure can slide on the base plate, and the support pad is set corresponding to the seat plate. The seat plate of the support structure can be fixedly connected to the base plate through the locking component. With different support pads, it can quickly and flexibly switch between various exercise modes such as crawling, crunching, and rowing. Attached Figure Description

[0051] To better understand the purpose, structure, and function of this utility model, the supporting structure and multifunctional crawler of this utility model will be described in detail below with reference to the accompanying drawings.

[0052] like Figures 1 to 27 As shown, the multi-functional crawler includes a first support structure 100, a second support structure 200, a third support structure 300, a fourth support structure 400, and a base plate 500. Each support structure includes a seat plate 101 and multiple interchangeable support pads. The base plate 500 has a track, and the support structure is set in the corresponding track so that the support structure can slide along the track on the base plate 500. The support pads are set corresponding to the seat plate 101. The seat plate 101 of the support structure can be fixedly connected to the base plate 500 through a locking component 108. With the help of different support pads, it can quickly and flexibly switch between various exercise modes such as crawling, crunching, and rowing.

[0053] like Figure 18 As shown, the user can lie prone on the fitness machine in a crawling posture, placing their upper and lower limbs on the support pads respectively to perform crawling exercises. Accordingly, the side of the base plate 500 that supports the user's upper limbs is defined as the front side of the multi-functional crawler, the side of the base plate 500 that supports the user's lower limbs is defined as the rear side of the multi-functional crawler, the side of the base plate 500 that supports the user's left side is defined as the left side of the multi-functional crawler, the side of the base plate 500 that supports the user's right side is defined as the right side of the multi-functional crawler, the side of the base plate 500 that is closer to the user is defined as the top surface of the multi-functional crawler, and the side of the base plate 500 that faces away from the user is defined as the bottom surface of the multi-functional crawler. The line connecting the front and rear sides is defined as longitudinal, the line connecting the left and right sides is defined as transverse, and the line connecting the top and bottom surfaces is defined as vertical.

[0054] Specifically, the base plate 500 of the multi-functional crawler is a rectangular plate structure. A movable structure is set in the middle of the longitudinal direction of the base plate 500 along the transverse direction, so that the front and rear sides of the bottom surface of the base plate 500 can move towards each other to fold, thereby reducing the footprint of the multi-functional crawler and achieving the effect of quick folding and storage. The activity structure divides the base plate 500 into a first region 501 on the front and a second region 502 on the rear. Four sets of tracks are then longitudinally arranged on the base plate 500: a first track 102 on the left side of the first region 501, a second track 103 on the right side of the first region 501, a third track 104 on the left side of the second region 502, and a fourth track 105 on the right side of the second region 502. Each set of tracks includes two parallel grooves, which are elongated grooves recessed towards the bottom surface of the base plate 500. These grooves accommodate two rows of rollers at the bottom of the square seat plate 101, allowing the support structure to reciprocate within the grooves of the base plate 500 in a first direction. In this embodiment, the first direction is longitudinal. This, combined with different support pads, enables various exercise modes such as crawling, crunches, and rowing.

[0055] Understandably, the top surfaces of the first region 501 and the second region 502 of the base plate 500 are divided by four rail grooves along the longitudinal direction, forming five rectangular planes arranged sequentially in the transverse direction. The plane between each group of rails is defined as the rail surface. The first rail surface is formed between the first rails 102, the second rail surface is formed between the second rails 103, the third rail surface is formed between the third rails 104, and the fourth rail surface is formed between the fourth rails 105. Several limiting holes 106 are arranged longitudinally at intervals on each rail surface to allow the locking component 108 to pass through and be inserted into the base plate 500, thereby limiting the support structure at different positions in the horizontal direction.

[0056] Furthermore, in this embodiment, the limiting hole 106 is configured as a transverse elongated hole structure, which is perpendicular to the force exerted by the slider structure in the longitudinal movement direction, thereby increasing the contact area of ​​the locking component 108 under pressure, dispersing stress and thus preventing it from breaking due to excessive pressure.

[0057] like Figure 3As shown, the top surfaces of the first region 501 and the second region 502 of the base plate 500 are divided by four rail grooves along the longitudinal direction, forming five rectangular base plates 500 arranged in a horizontal sequence. The top surfaces of these rectangular base plates 500 are provided with first flanges 503. The first flanges 503 are arranged horizontally on the edges of any two opposite top surfaces of the base plates 500, so that the second flanges 504 on the support structure can abut against the first flanges 503. The first flanges 503 are located on the fixing plates on both sides of the rollers of the support structure. The first flanges 503 cover the second flanges 504. When the user performs standing fly, squatting, or other movements, an upward pulling force will be generated on the support structure. At this time, the first flanges 503 can limit the second flanges 504 in the longitudinal direction, preventing the seat plate 101 of the support structure from being lifted upward and separated from the base plate 500, which could lead to injury or interruption of training. It is understandable that when performing horizontal movements such as crawling, crunching, and rowing, a certain upward force will be generated on the support structure. Therefore, the mutual abutment between the second flange 504 and the first flange 503 can improve the overall stability between the support structure and the base plate 500 in various movement modes.

[0058] like Figures 4 to 7 As shown, the first region 501 and the second region 502 of the base plate 500 are connected by a movable structure. In this embodiment, the movable structure is set as three folding components 505 arranged horizontally in sequence. The folding component 505 includes a pivot 506, a first bearing 507, a second bearing 508, a first cover plate 509, and a second cover plate 510. The pivot 506 includes a first axis and a second axis arranged opposite to each other and parallel to each other. One end of the two axes on the same side is fixed by a first connecting piece and a second connecting piece, respectively. The first bearing 507 and the first cover plate 509 are arranged opposite to each other on the upper and lower sides of the first axis. The second bearing 508 and the second cover plate 510 are arranged opposite to each other on the upper and lower sides of the second axis. The cover plate and the bearing are fixed by screws so that the first cover plate 509 and the second cover plate 510 arranged horizontally opposite to each other can rotate around the first axis and the second axis, respectively. The purpose of this structure is to set the folding component 505 inside the cover plate, thereby making the top and bottom surfaces of the base plate 500 relatively flat, improving the safety and aesthetics of the crawler, and facilitating folding and storage.

[0059] The cover plate is a three-dimensional plate structure extending laterally. The first cover plate 509 is opposite to the first region 501 of the base plate 500 and the two are fixedly connected by a concave-convex structure and bolts. The second cover plate 510 is opposite to the second region 502 of the base plate 500 and the two are fixedly connected by a concave-convex structure and bolts. Multiple ribs are arranged longitudinally below the top surface of the cover plate. These ribs can disperse local stress and, on the other hand, have downward-facing semi-circular grooves on the ribs opposite to the bearing bush. The grooves are used to accommodate the pivot 506 assembly. The upper half of the first or second shaft of the component, the bearing bush includes a bearing portion and an ear portion. The bearing portion is a semi-cylindrical structure, including an arc-shaped inner cylinder wall and an outer cylinder wall, forming a semi-circular ring structure with an upward opening in the longitudinal cross section. The lower half of the first or second shaft of the pivot 506 is placed in the groove formed by the inner cylinder wall. The two ear portions are arranged opposite to each other on the front and rear sides of the outer cylinder wall. After the bolt passes through the through hole on the ear portion, it enters the screw hole at the corresponding position on the cover plate, so that the bearing bush can rotate around the corresponding first or second shaft after being fixedly connected to the cover plate.

[0060] It is important to emphasize that, through the above structural design, the bearing and pivot 506 of the folding assembly 505 are housed inside the cover plate structure, resulting in a complete planar structure on both the top and bottom surfaces of the cover plate. This achieves a smooth and aesthetically pleasing connection between the first region 501 and the second region 502 of the base plate 500, making it easy to fold. More importantly, the cover plate in this invention serves as the connecting structure between the first region 501 and the second region 502 of the base plate 500. The top surface of the cover plate is also part of the structure relative to the human body after the multi-functional crawler is unfolded. The flatness of this structure affects not only the range of motion of the slide assembly but also directly the correctness, comfort, and safety of the movement posture. For example, during crawling, kneeling, and other movements, the knee joints and lower legs of the human body need to be moved or placed above the top surface of the cover plate. The flat top surface of the cover plate in the folding assembly 505 not only realizes the folding function of the base plate 500 but also allows the human body to safely and comfortably perform various movements on it.

[0061] It should be noted that the cover plate in this utility model can also be set as an integrally formed structure with the first region 501 and the second region 502. In this embodiment, it is set as a split structure in order to better adapt to the dynamic load changes during folding and movement. Especially when subjected to forces in different directions, allowing a certain relative movement between the bottom plate 500 and the rotating shaft helps to disperse stress and avoid damage caused by concentrated force.

[0062] Furthermore, the lower sides of the opposite sidewalls of the first cover plate 509 and the second cover plate 510 are arc-shaped, thereby creating a rotation space on the lower sides of the two sidewalls. This allows the bottoms of the first cover plate 509 and the second cover plate 510 to rotate towards each other while keeping their opposite sidewalls as close as possible, thereby reducing the gap between the first cover plate 509 and the second cover plate 510. This results in greater integrity after the cover plates are unfolded, improving the stability and aesthetics of the overall structure of the multi-functional crawler.

[0063] Understandably, in order to increase the longitudinal range of the support structure on the base plate 500, two limiting holes 106 are provided on the cover plate to allow the locking component 108 to be inserted. These limiting holes 106 are located on the same straight line as the limiting hole 10 on the rail surface.

[0064] Preferred, such as Figure 2 As shown, a storage slot 511 is horizontally provided on the front side of the first area 501 of the base plate 500. The storage slot 511 is used to insert electronic products such as mobile phones and tablets, so that users can watch videos with electronic products while exercising. The storage slot 511 makes full use of the thickness of the base plate 500 itself to be recessed downward to maintain the flatness of the top surface of the base plate 500, so that the center of gravity of the electronic products placed in it is close to the ground and has good stability. At the same time, the overall shape of the base plate 500 is simple and beautiful.

[0065] An auxiliary rod 512 is horizontally arranged on the rear side of the second region 502 of the base plate 500. The auxiliary rod 512 has an inverted U-shaped structure with a downward opening. When the base plate 500 is folded, the auxiliary rod 512 is positioned relative to the ground. The horizontal width of the auxiliary rod 512 is greater than its vertical height. This not only helps to support the fitness equipment in the folded state and prevent it from tilting, but also reduces the floor space occupied. In addition, when the base plate 500 is unfolded, the auxiliary rod 512 can also be used as a handle. Users can lift the base plate 500 by pulling the handle, making it easy to move the fitness equipment in the unfolded state.

[0066] Furthermore, first fixing rings 513 are provided at the four corners of the top surface of the base plate 500. The first fixing rings 513 have through holes for connecting the elastic pull rope 600. Figure 8 As shown, the elastic pull rope 600 includes a rope body and hooks at both ends of the rope body. One end of the hook can be further connected to a gripping part, thereby connecting the elastic pull rope 600 to the first fixing ring 513 on the front or rear side of the base plate 500. Combined with the support structure, it can perform rowing, Pilates kneeling stretch and other exercise modes, enhancing the flexibility and expandability of the multi-functional crawler.

[0067] A first support structure 100, a second support structure 200, a third support structure 300, and a fourth support structure 400 are provided on the top surface of the base plate 500, respectively corresponding to the first, second, third, and fourth rail surfaces of the base plate 500. Specifically, each support structure includes a square base plate 101, with two fixing pieces at each of the four corners of the bottom surface of the base plate 101. The two fixing pieces are arranged opposite each other, and transverse through holes are formed on the fixing pieces to fix the rollers between the two fixing pieces. Thus, four rollers are provided at the bottom of the base plate 101. The four rollers are symmetrically arranged in both the longitudinal and transverse directions, and are thus embedded in the two rail grooves of each rail and can slide longitudinally within them.

[0068] To limit the vertical movement of the seat plate 101 of the support structure, i.e., to prevent the support structure from moving upward and separating from the base plate 500, the first flange 503 on the base plate 500 and the second flange 504 on the fixing plate cooperate to limit the movement. It should be noted that in this embodiment, the second flange 504 on each support structure is only provided on the fixing plates near the left and right sides of the base plate 500. That is, each second flange 504 only forms a limiting effect with the first flange 503 on the top surface of the base plate 500 adjacent to the rail surface. This setting method can ensure the stability of the limiting effect and also reduce the number of second flanges 504, reducing the difficulty of processing and assembly. Those skilled in the art can set at least one set of first flange 503 and second flange 504 structure according to actual needs, as long as it can prevent the support structure from coming off and achieve the effect of stable sliding of the slide assembly within the rail of the base plate 500.

[0069] like Figures 9 to 12 As shown, a receiving portion 107 is formed on the seat plate 101 of the support structure for accommodating the locking component 108, and the locking component 108 fixes the support structure and the base plate 500 relatively in the horizontal direction, especially in the longitudinal direction. In this embodiment, the receiving portions 107 of the first support structure 100 and the second support structure 200 are all located on the rear side of their seat plates 101, and the receiving portions 107 of the third support structure 300 and the fourth support structure 400 are all located on the front side of their seat plates 101. The purpose of this arrangement is that the upper front side of the seat plate 101 of the first support structure 100 and the second support structure 200 is blocked by the support pad, and the upper rear side of the seat plate 101 of the third support structure 300 and the fourth support structure 400 is blocked by the lower limb support member 119. Therefore, by setting the receiving portion 107 in the above positions, the interference and obstruction caused by the above-mentioned obstruction structures when operating the locking component 108 in the receiving portion 107 can be avoided, thereby improving the convenience and safety of operation. Of course, those skilled in the art can also adjust the setting position of the receiving part 107 on the base plate 101 according to actual needs, as long as the locking component 108 can be moved within the receiving part 107.

[0070] It should be noted that the second support structure 200 and the first support structure 100 are both located on the first region 501 of the base plate 500 and are symmetrically arranged along the left and right sides of the base plate 500. The third support structure 300 and the fourth support structure 400 are located on the second region 502 of the base plate 500, and the third support structure 300 and the fourth support structure 400 are symmetrically arranged along the front and back sides of the base plate 500 with the first support structure 100 and the second support structure 200. The structures of the receiving part 107 and the locking component 108 on each support structure are the same, except for the change in the setting direction. Therefore, the following description only takes the receiving part 107 and the locking component 108 on the first support structure 100 as an example. How the receiving part 107 and the locking component 108 on other support structures are set can be obtained by mirroring the above positional relationship between the support structures, so it will not be described again.

[0071] The receiving portion 107 of the first support structure 100 includes a paddle groove 109 and a pin hole 110 that are interconnected. The paddle groove 109 has an opening facing the third support structure 300 and forms a groove in the longitudinal direction toward the center of the seat plate 101. This groove is connected to the vertically arranged pin hole 110. The cross-sectional dimensions of the pin hole 110 are adapted to the cross-sectional dimensions of the limiting hole 106 on the rail surface. The locking assembly 108 includes a plate-shaped pin 112 and a paddle 111. The pin 112 and the paddle 111 are vertically connected to form an integral structure with an inverted L-shaped cross-section. It should be noted that the seat plate 101 and the support pad are arranged in the longitudinal direction... The position away from its center in the lateral and transverse directions is defined as the edge. The paddle groove 109 of the receiving part 107 is located between the edge of the seat plate 101 and the edge of the support pad. When the paddle 111 is located in the paddle groove 109, the end of the paddle 111 away from the pin 112 protrudes from the edge of the seat plate 101 and the edge of the support pad. This is to facilitate the operation of the pin 112 by fingers. Of course, those skilled in the art can set the receiving part 107 on any edge of the seat plate 101 of the first support structure 100 according to actual needs, as long as the locking component 108 can achieve the effect of fixing and unlocking the support structure and the base plate 500.

[0072] In use, place the paddle 111 in the paddle slot 109 and press the paddle 111 from top to bottom to insert the pin 112 into the limiting hole 106 through the pin hole 110. This causes the first support structure 100 and the base plate 500 to form a limiting effect in the longitudinal direction. When it is necessary to unlock the limiting, lift the paddle 111 from bottom to top to dislodge the pin 112 from the limiting hole 106, thus completing the unlocking. The first support structure 100 then resumes sliding on the first track 102.

[0073] Understandably, when the pin 112 is inserted into the limiting hole 106, the vertical height of the portion of the pin 112 protruding downwards from the bottom surface of the base plate 101 is defined as the first length, and the maximum vertical distance that the paddle 111 can move within the paddle slot 109 is defined as the second length. The second length is not less than the first length. In other words, when the paddle 111 is lifted upwards to unlock, the paddle slot 109 must be able to provide sufficient displacement space so that the bottom of the pin 112 can be completely dislodged from the limiting hole 106; otherwise, unlocking cannot be completed.

[0074] Preferred, such as Figure 12 and 13 As shown, the support structure also includes a positioning component 113, which includes a ball 114, a spring, and a stud. The position on the base plate 101 that forms the pin hole 110 is defined as the pin hole wall. A locking hole is longitudinally provided on the pin hole wall of the base plate 101 below the paddle 111, that is, a locking hole is provided on the pin hole wall opposite to the positioning groove. A stud is provided in the locking hole, and a ball 114 is provided at one end of the stud near the pin 112. A spring is provided at the other end, and the spring abuts against the ball 114, so that the ball 114 is always subjected to an elastic force towards the side near the pin 112. A positioning groove is formed on the positioning surface of the pin 112 corresponding to the locking hole. The positioning groove includes a first groove 115 and a second groove 116, which are spaced apart relative to each other in the vertical direction. During the vertical movement of the pin 112, the ball 114... 4. Under the continuous force of the spring, when the ball 114 is opposite to the first groove 115 or the second groove 116, it is pressed into the groove by the spring. Thus, the ball 114 positions and stops the pin 112 in the vertical direction. When the ball 114 is pressed into the first groove 115 located above the pin 112, the pin 112 is held in the pin hole 110 and the pin 112 has completely disengaged from the limiting hole 106. Therefore, when the user selects the exercise mode that requires the sliding support structure, there is no need to repeatedly remove the locking component 108 from the seat plate 101. When the ball 114 is pressed into the second groove 116 located below the pin 112, it can improve the stability of the connection between the seat plate 101 and the track while positioning. In addition, it can also provide the user with operation feedback, so that the user can perceive that the support structure has reached a specific position of the limiting state with the base plate 500, thus improving the user experience.

[0075] It is understood that the first groove 115 and the second groove 116 are provided on the pin 112 in this embodiment. Those skilled in the art can also provide only the first groove 115 or the second groove 116 according to actual needs, which can also basically achieve the effect of quick positioning of the pin 112 and improve user experience. In addition, those skilled in the art can set the positioning groove on any side of the pin 112 according to actual needs, as long as a positioning component 113 corresponding to the positioning groove can be set on the pin hole wall to achieve the effect of positioning and locking the pin 112.

[0076] The top surface of the seat plate 101 of the support structure is provided with four cylindrical recesses, and the support pad is correspondingly positioned above the seat plate 101. The bottom surface of the support pad is provided with four cylindrical protrusions, which correspond one-to-one with the recesses on the seat plate 101 to form a snap-fit ​​connection. On the one hand, this restricts the horizontal movement of the support pad in the seat plate 101. The human body can place the upper limbs, lower limbs, and other parts on the support pad. The resulting vertical pressure further stabilizes the connection between the support pad and the seat plate 101. Combined with the aforementioned locking component 108, this enables various exercise modes such as crawling, rowing, and crunches. On the other hand, the snap-fit ​​connection allows the support pad to be manually and quickly separated from the seat plate 101 in the vertical direction, and the support pad can be quickly replaced without the need for tools. By setting support pads with different structures, it is possible to adapt to different specific movements in various exercise modes, such as hand gripping and arm support.

[0077] Of course, those skilled in the art can combine the number and shape of the above-mentioned concave and convex structures according to actual needs. It could be a cross-shaped structure in the middle, or three parallel straight structures, etc. The positions of the concave and convex structures can also be interchanged, as long as it achieves the effect of restricting the horizontal movement of the support pad on the seat plate 101, while allowing for quick disassembly and replacement of the support pad in the vertical direction. The purpose of setting the concave and convex structures in this embodiment as described above is that the four concave and convex structures are respectively located near the four corners of the square seat plate 101, which can effectively disperse external forces and horizontal loads, reduce the possibility of the support pad tipping over, and facilitate processing and assembly.

[0078] Furthermore, such as Figure 1 As shown, second fixing rings 117 are arranged opposite each other on the left and right sides of the seat plate 101 of the support structure. Combined with the aforementioned elastic rope 600, standing cross fly exercises can be performed. It can be further combined with a straight bar, with one end of an elastic rope 600 connected to each end of the straight bar, and the other end of the elastic rope 600 connected to the second fixing ring 117 to realize squat exercises, thereby improving the flexibility and expandability of the multi-functional crawler.

[0079] Furthermore, it also includes an armrest 118 and a lower limb support 119. A first extension is provided on the front side of the seat plate 101 of the first support structure 100 and the second support structure 200. In this embodiment, the first extension is an extension tube. The armrest 118 is a curved rod structure with an obtuse angle, including an extension rod and a handle connected together. The free end of the extension rod can be inserted into the extension tube. The extension tube is provided with a positioning hole. The positioning bead on the free end of the extension tube can be inserted into the positioning hole by the action of the spring below it, thereby realizing the detachable connection between the armrest 118 and the support structure. The extension is basically parallel to the base plate 500. The extension extends from the lower rear side to the front and upward. This structure allows the forearm to be placed on the support pad of the first support structure 100 and the second support structure 200, so that the hand naturally extends forward to hold the handle for exercise, thereby obtaining an ergonomic posture and force exertion state, improving the comfort and fitness effect of exercise.

[0080] Second extension portions are provided on the left side of the seat plate 101 of the first support structure 100, the right side of the seat plate 101 of the second support structure 200, the left side of the seat plate 101 of the third support structure 300, and the right side of the seat plate 101 of the fourth support structure 400. In this embodiment, the second extension portion is an extension groove. The lower limb support member 119 includes a fixed column and a support column arranged opposite and parallel to each other, and a connecting arm connecting the fixed column and the support column. The fixed column is inserted into the extension groove so that the support column is located above the corresponding support structure. It can be understood that the longitudinal section of the fixed column and the extension groove is set to be square. On the one hand, this allows the upper limit of the lower limb support member 119 in the longitudinal and vertical directions to be located at the seat plate 101 of the support structure. On the other hand, it allows the lower limb support members 119 on the third support structure 300 and the fourth support structure 400 to interchange positions, or as... Figure 14 As shown, it is positioned on the left side of the seat plate 101 of the first support structure 100 and the right side of the seat plate 101 of the second support structure 200, allowing the support column to switch between the front and rear positions of the seat plate 101. By providing this lower limb support 119, the lower legs or feet can be supported on the support column during activities such as horizontal crawling, abdominal muscle exercises, and rowing, assisting in the exertion of force and improving the comfort of the exercise. In addition, positioning structures can also be provided on the fixed column and the expansion slot, with the same structural function as the positioning holes of the aforementioned expansion tube and the positioning beads of the extension rod, which will not be described in detail here.

[0081] It is understood that the connection method between the armrest 118 and the seat plate 101, and between the lower limb support 119 and the seat plate 101 in this embodiment has the characteristics and effects of stable connection structure, easy assembly and high flexibility. Those skilled in the art can choose according to actual needs, or adopt other interlocking structures, or bolt fixing and other forms to achieve detachable connection, as long as the above effects can be basically achieved.

[0082] The support pad in this utility model is generally set as a rectangular plate structure. The support pad and the seat plate 101 on the same support structure are movably connected in a second direction. In this embodiment, the second direction is the vertical direction, that is, the support member is connected to the top surface of the seat plate 101 and is movably connected to the seat plate 101 in the vertical direction through the aforementioned concave and convex structure, thereby realizing the quick assembly and disassembly of the support pad and the seat plate 101. Of course, the second direction can also be set as the horizontal direction, that is, the support member is movably connected to the left or right side of the seat plate 101, which can also realize the limitation of the support pad in the first direction, while the support pad and the seat plate 101 can be quickly assembled and disassembled.

[0083] It should be particularly emphasized that the multifunctional crawler of this utility model includes at least two types of support pads, which can be quickly and interchangeably installed on the same seat plate 101, thereby achieving rapid adaptation to multiple different movement modes and improving the flexibility and expandability of the multifunctional crawler.

[0084] Specifically, such as Figures 15 to 17 As shown, the multifunctional crawler in this embodiment includes a first support pad 120, a second support pad 121, and a third support pad 122. The first support pad 120 is disposed on the seat plate 101 of the first support structure 100 and the second support structure 200. The longitudinal length of the first support pad 120 is greater than the longitudinal length of the corresponding seat plate 101. The first support pad 120 includes a base area and an extension area arranged sequentially. A transversely arranged elongated gripping hole 123 is formed on the extension area. When the first support pad 120 is connected to the seat plate 101 of the first support structure 100 and / or the second support structure 200, the base area and the support structure... The seat plate 101 is fixed to the aforementioned concave and convex structure. The extended area protrudes forward from the seat plate 101 of the support structure, so that the grip hole 123 is in a vertically through structural form. The structural function of the first support pad 120 is, on the one hand, to form a larger contact area, which is conducive to the human body fully supporting the forearm on the first support pad 120, increasing the force area during human exercise. On the other hand, the grip hole 123 of the extended part is used for the human hand to grasp, which is conducive to the stability of the body posture and the exertion of the target muscle group during exercise modes such as abdominal muscle training and mountain climbing, thereby realizing multiple exercise modes and improving exercise comfort and training effect.

[0085] The second support pad 121 is disposed on the seat plate 101 of each support structure. The longitudinal length of the second support pad 121 is basically the same as the longitudinal length of the seat plate 101 of each support structure, that is, the longitudinal length of the second support pad 121 is less than the longitudinal length of the first support pad 120. Therefore, after the second support pad 121 is combined with the seat plate 101 of the support structure, the second support pad 121 can be completely placed on the seat plate 101, thereby providing a more stable support effect when the human body is skiing, rowing and other sports.

[0086] The third support pad 122 is made of soft material. In this embodiment, EVA material is used, but PU and other materials can also be used. The third support pad 122 is set on the seat plate 101 of each support structure to improve the comfort of the human body when performing actions that require the limbs to directly contact the third support pad 122, such as kneeling extension and abdominal crunch.

[0087] It should be noted that in this embodiment, the end of the support pad near the lever 111 does not completely correspond to the lever 111 of the locking component 108 in the vertical direction. In other words, the lever 111 of the locking component 108 protrudes from the support pad in the vertical direction. The purpose of this structure is that, on the one hand, the part of the lever 111 protruding from the support pad is easy to adjust by hand, and on the other hand, the part of the lever 111 corresponding to the support pad can stop and limit the support piece in the longitudinal direction, so as to avoid excessive force when pulling the lever 111 upward and completely pulling it out, thus avoiding misoperation and improving the user experience.

[0088] It is understood that those skilled in the art can arrange and combine the specific dimensions, hardness, coefficient of friction, and placement of the support pad according to actual needs, such as... Figures 18 to 27 As shown, a support pad is formed for various sports modes such as crawling, mountain climbing, crunches, skiing, skating, rowing, kneeling stretches, standing flyes, and standing squats. As long as it can adapt to multiple different sports modes, it can enhance the flexibility and expandability of the multi-functional crawler.

[0089] The support structure and multifunctional fitness device of this utility model have the following advantages:

[0090] 1. The locking component and the receiving part of the seat plate, as well as the support pad, cooperate with each other, so that one end of the locking component protrudes from the support pad and the seat plate, which makes the locking component convenient and efficient to operate, without affecting the replacement of the support pad.

[0091] 2. The support pad is connected to the seat plate through a snap-fit ​​structure, which restricts the horizontal movement of the support pad on the seat plate and allows for quick replacement of the support pad without the need for tools, making it easy to disassemble and assemble.

[0092] 3. The locking component is positioned by setting a positioning groove on the pin, which makes the operation more convenient for users, enhances the user's perception during operation, and improves the user experience.

[0093] 4. The support structure can slide on the base plate, and the support pad is set corresponding to the seat plate. The seat plate of the support structure can be fixedly connected to the base plate through the locking component. With different support pads, it can quickly and flexibly switch between various exercise modes such as crawling, crunching, and rowing.
