Detailed Implementation

[0047] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —9: Example 1: See Figure 1-7 : A crawling machine includes a walking platform 1 and a hand-climbing platform 2. The hand-climbing platform 2 is provided with a front telescopic mechanism and a rear telescopic mechanism. One end of the front telescopic mechanism is hinged to the hand-climbing platform 2 and locked to the hand-climbing platform 2 by a locking mechanism. The other end of the front telescopic mechanism is a support end. One end of the rear telescopic mechanism is hinged to the hand-climbing platform 2 and locked to the hand-climbing platform 2 by a locking mechanism. The other end of the rear telescopic mechanism is hinged to the walking platform 1 and locked to the walking platform 1 by a locking mechanism.

[0048] The working principle of this utility model is as follows: Figure 1-7 As shown, when it is necessary to adjust the position and angle of the hand-climbing platform 2, loosen each locking mechanism, adjust the length and tilt angle of the front telescopic mechanism and the rear telescopic mechanism, and after adjustment, tighten each locking mechanism.

[0049] Both the front and rear telescopic mechanisms are vertically aligned and of equal length. When the lower end of the front telescopic mechanism contacts the ground, the hand-climbing platform 2 and the walking platform 1 are parallel. Figure 1 As shown, it can be used for crawling movements.

[0050] Both the front and rear telescopic mechanisms are vertically arranged, but the front telescopic mechanism is longer than the rear telescopic mechanism. When the lower end of the front telescopic mechanism contacts the ground, the hand-climbing platform 2 is tilted relative to the walking platform 1. Figure 2 As shown, it can be used for crawling motion and meets users' needs for different crawling angles.

[0051] When the current telescopic mechanism and the rear telescopic mechanism are in a horizontal state, the hand-climbing platform 2 and the walking platform 1 are on the same horizontal plane, such as... Figure 3 As shown, it can be used for crawling movements where the front and back feet are at the same height.

[0052] When the current telescopic mechanism supports the ground, the rear telescopic mechanism is in an inclined state, and the hand-climbing platform 2 is in an upright state, such as Figure 4 As shown, it can be used for running or for temporary storage to reduce space usage.

[0053] When the hand-climbing platform 2 is attached to the top of the walking platform 1, and the crawling machine is in a folded state, as follows: Figure 5 As shown, it is used for storage, effectively saving space.

[0054] The walking treadmill 1 and the hand-climbing treadmill 2 of this utility model are hinged together by a rear telescopic mechanism, and the front end of the hand-climbing treadmill is supported by a hinged front telescopic mechanism, which can realize the conversion between different states of the walking treadmill 1 and the hand-climbing treadmill 2. The locking mechanism can be used to lock the treadmill in a stable state after conversion. The walking treadmill 1 and the hand-climbing treadmill 2 of this utility model have multiple states. The hand-climbing treadmill can be tilted to meet the diverse needs of users. Moreover, when it is in the folded state, it occupies little space and is easy to store.

[0055] To ensure the stability of the crawler structure, two front telescopic mechanisms are provided, located on the left and right sides of the hand-climbing platform 2, respectively. Two rear telescopic mechanisms are also provided, located on the left and right sides of the hand-climbing platform 2, respectively.

[0056] To ensure the strength of the front telescopic mechanism when it plays a supporting role, a connecting rod 18 is connected between the two front telescopic mechanisms, and the connecting rod 18 is located at the end of the front telescopic mechanism away from the hand-climbing platform 2.

[0057] To protect the floor, a foot pad is fitted on the end of the front telescopic mechanism away from the hand-climbing platform.

[0058] Structure of the locking mechanism: such as Figure 1-6 As shown, the locking mechanism includes a mounting plate 3 mounted on the running platform and a locking device mounted on the telescopic mechanism. The telescopic mechanism is hinged to the corresponding mounting plate 3 via a hinge shaft. The mounting plate 3 has an arc-shaped groove 4, the center of which is coaxial with the corresponding hinge shaft. When the locking device is unlocked, the locking rod of the locking device slides within the arc-shaped groove 4, allowing the telescopic mechanism to rotate relative to the mounting plate 3. When the locking device is locked, the telescopic mechanism cannot rotate relative to the mounting plate 3. The structure is simple and easy to manufacture and install.

[0059] Furthermore, the running platform includes a walking running platform 1 and a hand-climbing running platform 2, and the telescopic mechanism includes a front telescopic mechanism and a rear telescopic mechanism.

[0060] Structure of the locking device: such as Figure 1-7As shown, the mounting plate 3 is installed on the side of the running track, and the telescopic mechanism is installed on the side of the mounting plate 3 away from the running track. The side of the mounting plate 3 closest to the running track is provided with an extension boss 5 installed on the side of the running track. The locking device is a combination of a bolt and a flathead hand-tightening nut 6. The locking rod of the locking device is the shank of the bolt. The shank of the bolt passes through the telescopic mechanism and the arc-shaped groove 4 in sequence and is screwed to the flathead hand-tightening nut 6. When the end of the flathead hand-tightening nut 6 abuts against the extension boss 5, the rotation of the flathead hand-tightening nut 6 is restricted.

[0061] During the locking process of the locking device, one hand holds the flathead hand-tightening nut 6 to restrict its axial movement, while the other hand rotates the bolt. After the bolt rotates to a certain angle, one end of the flathead hand-tightening nut 6 abuts against the extension boss 5 to restrict the flathead hand-tightening nut 6 from continuing to rotate. The bolt rotates and moves relative to the flathead hand-tightening nut 6, thus achieving locking.

[0062] During the unlocking process of the locking device, one hand holds the flathead hand-tightening nut 6 to restrict its axial movement, while the other hand rotates the bolt. After the bolt rotates a certain angle in the opposite direction, the other end of the flathead hand-tightening nut 6 abuts against the extension boss 5 to restrict the flathead hand-tightening nut 6 from continuing to rotate. The bolt rotates and moves relative to the flathead hand-tightening nut 6, thus unlocking the device.

[0063] Preferably, the mounting plate 3 and the extension boss 5 are an integral structure.

[0064] Furthermore, the mounting plate 3 of the locking mechanism of the front telescopic mechanism and the locking mechanism of the hand-climbing platform 2 is fixedly installed on the hand-climbing platform 2, and the mounting plate 3 of the locking mechanism of the rear telescopic mechanism and the locking mechanism of the walking platform 1 is fixedly installed on the walking platform 1. A slide plate 10 is detachably connected to the hand-climbing platform 2 via a detachable connecting device. The mounting plate 3 of the locking mechanism of the rear telescopic mechanism and the locking mechanism of the hand-climbing platform 2 is fixedly installed on the slide plate 10. When the detachable connecting device is in the detached state, the slide plate 10 can move back and forth along the hand-climbing platform 2; when the detachable connecting device is in the connected state, the slide plate 10 is fixed on the hand-climbing platform 2. The hinge position between the rear telescopic mechanism and the hand-climbing platform 2 is adjustable to adapt to different states of the crawling machine.

[0065] In this embodiment, the mounting plate 3 is fixed to the hand-climbing running platform 2 by welding, the mounting plate 3 is fixed to the walking running platform 1 by welding, and the mounting plate 3 is fixed to the sliding plate 10 by welding.

[0066] In this embodiment, the detachable connecting device has the following structure: the detachable connecting device includes bolts, nuts, and multiple mounting holes provided on the hand-climbing platform 2. When the shank of the bolt passes through the mounting hole and the slide plate 10 is screwed to the nut, the detachable connecting device is in a connected state, and the slide plate 10 is fixed on the hand-climbing platform 2. When the nut and bolt are removed, the detachable connecting device is in a disassembled state, and the slide plate 10 can move back and forth along the hand-climbing platform 2.

[0067] The specific structure of the front telescopic mechanism and the rear telescopic mechanism: The front telescopic mechanism and the rear telescopic mechanism are slide rails with locking mechanisms.

[0068] Furthermore, the slide rail includes an outer rail 11 and an inner rail 12 that slides within the outer rail 11. The outer rail 11 of the front telescopic mechanism is hinged to the hand-climbing platform 2, the outer rail 11 of the rear telescopic mechanism is hinged to the hand-climbing platform 2, and the inner rail 12 of the rear telescopic mechanism is hinged to the walking platform 1.

[0069] In this embodiment, the slide rail and the mounting plate 3 are hinged: the shank of the bolt passes through the outer rail 11 or the inner rail 12 and is screwed to the mounting plate 3, and the outer rail 11 or the inner rail 12 is rotatably mounted on the shank of the bolt.

[0070] The structure of the walking treadmill 1 and the hand-climbing treadmill 2: The walking treadmill 1 and the hand-climbing treadmill 2 each include two parallel side plates, a running board connecting the two side plates, a running belt mounted on the running board, and a motor driving the running belt. The two side plates of the hand-climbing treadmill 2 are each equipped with foldable handrails 13 at their rear ends. When this invention is used for running, the handrails 13 are unfolded, meeting the requirement that treadmills must be equipped with handrails; when this invention is used for crawling or storage, the handrails 13 are folded.

[0071] Furthermore, the slide plate 10 is C-shaped with an opening at the top, and the slide plate 10 is arranged around the outer perimeter of the side plate.

[0072] Preferably, the walking platform 1 has rollers 14 at its front end and a support column 15 at its bottom. The rollers 14 facilitate the movement of this walking machine.

[0073] Furthermore, the front end of the walking platform 1 is provided with a connecting pipe 1, and the lower front end of the hand-climbing platform 2 is provided with a connecting pipe 2. When the hand-climbing platform 2 is in an upright position, the connecting pipe 1 is inserted into the connecting pipe 2 or the connecting pipe 2 is inserted into the connecting pipe 1, and the connecting pipe 1 and the connecting pipe 2 are fixed by a pin to fix the walking platform 1 and the hand-climbing platform 2. When it is necessary to change the state, the pin can be pulled out.

[0074] Example 2: See Figure 8 : This embodiment is basically the same in structure as Embodiment 1 above, with the main difference being that the locking device includes a quick-release wrench 7, a quick-release rod core 8, and an adjusting nut 9. The locking rod of the locking device is the quick-release rod core 8, with one end hinged to the cam end of the quick-release wrench 7 and the other end screwed to the adjusting nut 9. The quick-release rod core 8 passes sequentially through the telescopic mechanism and the arc-shaped groove 4. The telescopic mechanism and the mounting plate 3 are positioned between the quick-release rod core 8 and the adjusting nut 9. When the base circle portion of the cam end of the quick-release wrench 7 presses against the telescopic mechanism, the locking device is in the unlocked state; when the protruding portion of the cam end of the quick-release wrench 7 presses against the telescopic mechanism, the locking device is in the locked state. The structure is simple and easy to adjust.

[0075] Example 3: See Figure 9 : This embodiment is basically the same as the structure of the first embodiment above. The main difference is that the front telescopic mechanism and the rear telescopic mechanism are pneumatic rods with locking mechanisms.

[0076] Furthermore, the pneumatic rod includes an outer sleeve 16 and a telescopic rod 17 slidably disposed within the outer sleeve 16. The telescopic rod 17 of the front telescopic mechanism is hinged to the hand-climbing running platform 2, the telescopic rod 17 of the rear telescopic mechanism is hinged to the hand-climbing running platform 2, and the outer sleeve 16 of the rear telescopic mechanism is hinged to the walking running platform 1.

[0077] In this embodiment, the hinge structure between the pneumatic rod and the mounting plate 3 is as follows: a pin is welded to the outer sleeve 16 or the telescopic rod 17, and a cotter pin is inserted after the pin passes through the mounting plate 3. The cotter pin limits the mounting plate 3, and the mounting plate 3 is rotated and fitted onto the pin.

[0078] Example 4: This embodiment has a structure that is basically the same as that of Embodiment 1 above. The main difference is that the front telescopic mechanism and the rear telescopic mechanism are electric push rods, which facilitates the automatic lifting and lowering of the front telescopic mechanism and the rear telescopic mechanism.

[0079] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model.
