[0022] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0023] Reference Figs. 1 to 3 A mechanical dog anti-mud foot structure, including leg pole 1 and anti-skid foot 2, leg pole 1 is detachably connected with the lower leg arm of the mechanical dog, and the anti-skid foot 2 is located at the bottom end of the leg pole 1. The material of the anti-skid foot 2 is rubber, which is soft in texture and can realize anti-skid and shock absorption.

[0024] The bottom of the anti-skid foot 2 is in a round head structure, which is used to adapt to the uneven ground and ensure the posture stability of the main body of the mechanical dog.

[0025] The above-mentioned mechanical dog anti-mud foot structure further includes a lower connecting ring 3, a flexible umbrella cover 4, an upper connecting ring 5 and an oblique skirt 6. The flexible umbrella cover 4 and the oblique skirt 6 are both used to deform when sinking into the mud to generate a large downward resistance and relieve the further sinking of the leg pole 1.

[0026] The lower connecting ring 3 is located on the leg pole 1, and the flexible umbrella cover 4 is connected with the lower connecting ring 3. The lower connecting ring 3 is used to fix the flexible umbrella cover 4.

[0027] The flexible umbrella cover 4 includes a cover body 41, which is in an expanded structure and the expanded end faces the anti-skid foot 2, so that the cover body 41 as a whole is in an umbrella structure, which can generate a large downward resistance when contacting with the mud.

[0028] The upper connecting ring 5 is located on the leg pole 1, and the oblique skirt 6 is connected with the upper connecting ring 5. The upper connecting ring 5 is used to fix the oblique skirt 6, and the oblique skirt 6 is arranged in an inclined manner relative to the length direction of the leg pole 1. The oblique skirt 6 can generate a large downward resistance when contacting with the mud.

[0029] The diameter of the expanded end of the cover body 41 is larger than the diameter of the connection between the cover body 41 and the lower connecting ring 3, so as to form an umbrella structure with the opening downward.

[0030] The cover body 41 is provided with a gap 42, and the gap 42 penetrates the inside and outside of the cover body 41.

[0031] The slits 42 extend along the generatrix of the cover body 41, and the slits 42 are arranged in a circumferential array relative to the lower connecting ring 3. The presence of the slits 42 facilitates the diffused deformation of the lower part of the cover body 41 after contacting the mud, thereby increasing the contact area of the cover body 41 with the mud and reducing the pressure.

[0032] The cover body 41 is made of a flexible material and can deform under stress and restore. The lower connecting ring 3 is detachably connected with the leg rod 1, specifically by screw connection or adhesive connection.

[0033] The slanted skirt portion 6 is arranged in a circumferential array relative to the upper connecting ring 5, which can ensure that the upper connecting ring 5 is uniformly stressed. The end of the slanted skirt portion 6 away from the upper connecting ring 5 is inclined towards the outside away from the leg rod 1. When contacting the mud, the lower part of the slanted skirt portion 6 expands and spreads, thereby increasing the contact area of the slanted skirt portion 6 with the mud and reducing the pressure.

[0034] The upper connecting ring 5 is located above the lower connecting ring 3. The upper connecting ring 5 is detachably connected with the leg rod 1, specifically by screw connection or adhesive connection.

[0035] The slanted skirt portion 6 is made of a flexible material and can deform under stress and restore. The hardness of the slanted skirt portion 6 is greater than that of the flexible umbrella cover 4. The flexible umbrella cover 4 serves as a first level component for relieving the continuous sinking of the leg rod 1 into the mud, and the slanted skirt portion 6 serves as a second level component for relieving the continuous sinking of the leg rod 1 into the mud.

[0036] The working principle of the utility model is as follows:

[0037] First, the upper end of the leg rod 1 is connected with the lower leg arm end of the leg part of the mechanical dog, until the four lower leg arm ends of the mechanical dog are respectively connected with the corresponding leg rod 1. At this time, the mechanical dog can be used for walking.

[0038] When the mechanical dog walks in a muddy environment or scene, due to the weight of the mechanical dog, the anti-skid foot 2 at the bottom end of the leg rod 1 will sink into the mud. As the leg rod 1 continues to sink, the flexible umbrella cover 4 begins to contact the mud.

[0039] Due to the umbrella shape of the flexible umbrella cover 4 and the downward flaring, a large resistance is formed when the leg rod 1 continues to sink. After the cover body 41 of the flexible umbrella cover 4 contacts the mud, the cover body 41 deforms under stress, the contact area of the cover body 41 with the mud increases, and a certain gravity can be borne, thereby avoiding the continuous sinking of the leg rod 1 to a certain extent.

[0040] When the flexible umbrella cover 4 sinks into the mud, the oblique skirt part 6 at the upper part will contact the mud water. The oblique skirt part 6 will be deformed by force, the contact area between the oblique skirt part 6 and the mud water is increased, a certain gravity can be borne, and the resistance of the oblique skirt part 6 and the increase of the sinking is continued, under the cooperation of the flexible umbrella cover 4 and the oblique skirt part 6, the leg rod 1 is prevented from continuing to sink.

[0041] When the mechanical dog needs to walk, the leg rod 1 needs to be lifted from the mud water, the main body of the mechanical dog drives the leg movement, the leg rod 1 moves upward relative to the mud water, at this time the flexible umbrella cover 4 and the oblique skirt part 6 will be retracted under the damping action of the mud water, that is, the lower edge of the cover body 41 and the lower edge of the oblique skirt part 6 are reduced in diameter, thereby reducing the resistance between the mud water, which is helpful for the smooth lifting of the leg rod 1, and further is conducive to the walking movement of the mechanical dog.

[0042] The above embodiments are used to further illustrate the present application, but the present application is not limited to these specific embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be understood as within the protection scope of the present application.
