[0046] See also Figures 1 to 3As shown, the present application provides an anti-sinking jack frame, which includes a frame body 1000, a front wheel mechanism 2000 and a rear wheel mechanism 3000. The frame body 1000 includes a frame front part, a frame middle part and a frame rear part. It should be noted that the frame front part, the frame middle part and the frame rear part are not divisions of parts or mechanical structures of the frame body 1000, but divisions of regions of the frame body 1000. The division of the regions can clearly understand the assembly positions of the front wheel mechanism 2000 and the rear wheel mechanism 3000 on the frame body 1000, and understand the assembly position relationship of each mechanism or part in the entire anti-sinking jack frame.

[0047] See also Figure 1 As shown, the front wheel mechanism 2000 includes a front wheel shaft assembly 2100 and at least two front wheel bodies 2200. The front wheel shaft assembly 2100 is assembled at the front part of the frame of the frame body 1000. Both ends of the front wheel shaft assembly 2100 are assembled along the front wheel rotation axis to rotate and assemble at least one front wheel body 2200. Figure 1 As shown, the front wheel shaft assembly 2100 is transversely arranged at the front part of the frame of the frame body 1000, and the two ends of the front wheel shaft assembly 2100 extend from the left and right sides of the front part of the frame of the frame body 1000 respectively. A front wheel body 2200 is assembled at both ends of the front wheel shaft assembly 2100, and the two front wheel bodies 2200 can rotate along the front wheel rotation axis, so that the front wheel body 2200 in the front wheel mechanism 2000 is set as a linear wheel that can move in a straight line when rotating. Among them, the fixed axis rotation means the rotation with the shaft fixed, that is, when the rigid body rotates with the shaft fixed, the points on the shaft remain stationary, and the angular velocity and speed of other points are not the same, wherein the axis can be on the rigid body or outside the rigid body, and the definition of fixed axis rotation is the same below.

[0048] The rear wheel mechanism 3000 includes at least two rear wheel shaft assemblies 3100 and at least two rear wheel bodies 3200. The rear part of the frame of the frame body 1000 is equipped with at least two rear wheel shaft assemblies 3100, wherein at least one rear wheel shaft assembly 3100 is assembled on both the left and right sides of the rear part of the frame, and at least one rear wheel body 3200 is rotatably assembled on each rear wheel shaft assembly 3100. Figure 1 As shown, a rear wheel shaft assembly 3100 is mounted on both sides of the rear portion of the frame of the frame body 1000, and two rear wheel shaft assemblies 3100 are symmetrically mounted on the left and right sides of the rear portion of the frame. A rear wheel body 3200 is rotatably mounted on each rear wheel shaft assembly 3100, so that two rear wheel bodies 3200 are also rotatably mounted on the left and right sides of the rear portion of the frame of the frame body 1000, and the two rear wheel bodies 3200 cooperate with the two front wheel bodies 2200 in front.

[0049] The rear wheel axle assembly 3100 is different from the front wheel axle assembly 2100, wherein the rear wheel axle assembly 3100 includes a rear wheel assembly main body seat 3110 and a rear wheel assembly rotating seat 3120, wherein the rear wheel assembly main body seat 3110 is assembled at the rear of the frame, the rear wheel assembly rotating seat 3120 is assembled on the rear wheel assembly main body seat 3110 for fixed axis rotation along a first rear wheel rotating axis, the rear wheel body 3200 is assembled on the rear wheel assembly rotating seat 3120 for fixed axis rotation along a second rear wheel rotating axis, the first rear wheel rotating axis is perpendicular to the front wheel rotating axis, and the second rear wheel rotating axis is perpendicular to the first rear wheel rotating axis.

[0050] It can be seen from this that the rear wheel assembly rotating seat 3120 is assembled on the rear wheel assembly main body seat 3110 along the first rear wheel rotating axis, and the first rear wheel rotating axis is perpendicular to the front wheel rotating axis, so that in addition to its own fixed-axis rotation during walking, the rear wheel body 3200 can also adjust the rotation direction as the rear wheel assembly rotating seat 3120 rotates relative to the rear wheel assembly main body seat 3110 after being assembled on the rear wheel assembly rotating seat 3120.

[0051] Therefore, by sequentially rotating and assembling the rear wheel assembly main body 3110, the rear wheel assembly rotating seat 3120 and the rear wheel body 3200, the rear wheel body 3200 is not limited to rotating in a straight line, but can adjust the rotation direction of the rear wheel body 3200 at will, forming a universal wheel that can rotate in all directions when rotating. The universal wheel that can rotate in all directions here means that the rear wheel body 3200 can rotate 360 ​​degrees along the first rear wheel rotation axis through the rear wheel assembly rotating seat 3120, and this rotation can realize the universal rotation of the rear wheel body 3200.

[0052] The overall anti-sinking jack frame is constructed as a front wheel body 2200 of the front wheel mechanism 2000, which is a linear wheel that can move in a straight line when rotating, and the front wheel body 2200 of the rear wheel mechanism 3000 is a universal wheel that can rotate in all directions when rotating, which can improve the flexibility of rotation. In addition, in a desert environment, the front wheel body 2200 of the rear wheel mechanism 3000 is constructed as a universal wheel that can rotate in all directions when rotating, so the angle of the anti-sinking jack frame can be appropriately adjusted in the desert environment. For example, the anti-sinking jack frame can be fixed in position by the front wheel mechanism 2000, and then the rear wheel mechanism The 3000 degree universal rotation realizes the fine adjustment of the overall angle of the anti-sinking jack frame, so that the anti-sinking jack frame can be fine-tuned in direction according to the actual situation of the desert environment, and the appropriate specific area can be selected to determine the setting position of the anti-sinking jack frame, which can not only find the position and angle suitable for the desert terrain, but also match the angle and position of the vehicle in a targeted manner. This is an innovative application in the position adjustment of the jack device. The above method can effectively prevent the anti-sinking jack frame from sinking into the desert, and improve the stability of the jack device in jacking work.

[0053] In one embodiment, the side wall of the rear wheel assembly main body seat 3110 is provided with at least one lateral widening portion 3110a, and the lateral widening portion 3110a can be a square body, a cone body, a platform body, or other regular three-dimensional shapes or other irregular three-dimensional shapes. The provision of the lateral widening portion 3110a can increase the overall structural width of the rear wheel assembly main body seat 3110. When the anti-sinking jack frame sinks into the desert under special circumstances, the widened rear wheel assembly main body seat 3110 can be used to increase the contact area with the desert, thereby preventing the anti-sinking jack frame from further sinking into the desert. The lateral widening portion 3110a is integrally formed with the rear wheel assembly main body seat 3110 or the lateral widening portion 3110a is detachably connected to the rear wheel assembly main body seat 3110.

[0054] In one embodiment, the rear wheel assembly rotating seat 3120 includes a turntable seat 3120a and a support plate 3120b. The turntable seat 3120a has a turntable top and a turntable bottom, the turntable top of the turntable seat 3120a is assembled with the rear wheel assembly main seat 3110 through the first rear wheel rotating shaft, the axis of the first rear wheel rotating shaft is used to constitute the first rear wheel rotating axis, and in the direction from the turntable top to the turntable bottom of the turntable seat 3120a, the diameter of at least a part of the turntable structure of the turntable seat 3120a gradually decreases. For example, the turntable seat 3120a may adopt an inverted terrace-shaped structure. In this embodiment, in the direction from the top end to the bottom end of the turntable of the turntable seat 3120a, the diameter of the entire turntable structure of the turntable seat 3120a gradually decreases. At this time, the terrace-shaped side wall of the inverted terrace-shaped body may constitute the disk sand discharge slope 3120a1, or the partial disk structure of the turntable seat 3120a near the bottom end of the turntable is designed as a structure with a gradually decreasing diameter, and the disk sand discharge slope 3120a1 for discharging sand may be formed on the side wall of the turntable seat 3120a near the bottom end of the turntable.

[0055] When the anti-sinking jack frame sinks into the desert under special circumstances, the disc sand discharge slope 3120a1 can be used to increase the contact area with the desert, thereby preventing the anti-sinking jack frame from sinking further into the desert. It should be noted that the disc sand discharge slope 3120a1 can be set to a suitable angle, for example, the inclination angle relative to the axial direction of the turntable seat 3120a can be between 60° and 90°, and a larger inclination angle can prevent sinking into the desert.

[0056] The support plates 3120b may include two, and the two support plates 3120b are symmetrically arranged at the bottom of the turntable of the turntable seat 3120a. The rear wheel body 3200 is assembled between the two support plates 3120b through the second rear wheel rotation axis, and the axis of the second rear wheel rotation axis is used to constitute the second rear wheel rotation axis. The two support plates 3120b can be assembled at the bottom of the turntable of the turntable seat 3120a by bolts or buckles, and the two support plates 3120b can be perpendicular to each other or the two support plates 3120b can be inclined relative to each other.

[0057] In one embodiment, the wheel body diameter of the front wheel body 2200 is greater than or equal to the wheel body diameter of the rear wheel body 3200, and the wheel body width of the front wheel body 2200 is greater than or equal to the wheel body width of the rear wheel body 3200. For example, the wheel body diameter of the front wheel body 2200 is greater than the wheel body diameter of the rear wheel body 3200, and the wheel body width of the front wheel body 2200 is greater than the wheel body width of the rear wheel body 3200, so that the front wheel body 2200 is larger in structural size than the rear wheel body 3200, presenting a design structure of a large front wheel and a small rear wheel.

[0058] See also Figure 1a and Figure 1b As shown, in one embodiment, the wheel body surface of the front wheel body 2200 and the wheel body surface of the rear wheel body 3200 are both provided with at least one circle of circumferential concave-convex patterns 2210, and each circle of circumferential concave-convex patterns 2210 includes a plurality of raised unit portions 2211, wherein the plurality of raised unit portions 2211 surround one circle along the circumferential direction of the wheel body surface to form a circle of circumferential concave-convex patterns 2210. For example, the wheel body surface of the front wheel body 2200 and the wheel body surface of the rear wheel body 3200 are both provided with a plurality of circles of circumferential concave-convex patterns 2210, and the plurality of circles of circumferential concave-convex patterns 2210 are arranged parallel to each other along the wheel body surface of the front wheel body 2200 or the wheel body surface of the rear wheel body 3200.

[0059] See also Figure 1a and Figure 1b As shown, in one embodiment, at least a portion of the side wall of the raised unit portion 2211 has a sand discharge guiding inclined surface 2211a that gradually tilts outward from the top to the bottom, and the side wall of the raised unit portion 2211 is also provided with at least one sand discharge inner recess 2211b that is recessed inward. When the anti-sinking jack frame is trapped in the desert under special circumstances, the sand discharge guiding inclined surface 2211a can be used to increase the contact area between the wheel body surface of the front wheel body 2200 and the wheel body surface of the rear wheel body 3200 and the desert, thereby preventing the anti-sinking jack frame from further sinking into the desert. In addition, the sand discharge inner recess 2211b can also discharge sand in the desert to the side, reducing the degree to which the front wheel body 2200 and the rear wheel body 3200 sink into the desert.

[0060] See also Figure 1a and Figure 1b As shown, in one embodiment, the wheel body surface of the front wheel body 2200 and the wheel body surface of the rear wheel body 3200 are both provided with two circles of circumferential concave-convex patterns 2210, wherein the multiple raised unit portions 2211 included in the two circles of circumferential concave-convex patterns 2210 are staggered with each other in the circumferential direction of the wheel body surface, and the sand-removing inner recesses 2211b opened on all the raised unit portions 2211 included in the two circles of circumferential concave-convex patterns 2210 are respectively arranged in opposite directions.
