[0037] Referring to Figures 1-9 , an adjustable universal wheel base of the present utility model includes a base main body 1. A plurality of extended connection and cooperation parts 12 are provided on the lower end face of the base main body 1, and a plurality of moving rollers 2 are provided at the edge; and a formed limiting base 3 is slidably arranged on the connection and cooperation parts 12; an adjusting member 4, the adjusting member 4 is rotatably connected to the limiting base 3 to adjust the distance between the limiting base 3 and the base main body 1. Using the formed base main body 1 as the contact main body with the object to be supported, in actual manufacturing, an opening-outward placing groove 10 can be formed on the upper end face of the base main body 1, and a raised texture is formed on the inner bottom wall of the groove to increase the contact friction; and the connection and cooperation parts 12 formed on the lower end face of the base main body 1 are used to connect with the limiting base 3, and the adjusting member is arranged on the limiting base 3 to control the distance between the two. When moving, the adjusting member 4 is toggled to control the limiting base 3 to be close to the base main body 1 and away from the ground, and the moving rollers 2 contact the ground for easy rolling movement. When it is not necessary to move, the adjusting member 4 is controlled to make the limiting base 3 away from the base main body 1 and contact the ground, so that the moving rollers 2 arranged on the base main body 1 are away from the ground. At this time, the limiting base 3 serves as the support base of the entire base.

[0038] Specifically, the limiting base 3 includes a receiving base 30, and the receiving base 30 is located below the adjusting member 4; an adjusting column 31, the adjusting column 31 is arranged on the upper end face of the receiving base 30, and the adjusting member 4 is rotatably connected to the adjusting column 31. The limiting base 3 is set to be composed of the receiving base 30 and the adjusting column 31. The adjusting column 31 is used to connect with the base main body 1 to achieve a certain stability between the two, and the adjusting member 4 is arranged on the upper side thereof; the receiving base 30 is used to serve as the main support base structure when the entire base is stationary.

[0039] In this embodiment, more specifically, to achieve the connection stability between the formed receiving base 30 and the base body 1, a convex connecting portion 11 with a mating groove 101 is provided on the lower end face of the base body 1, and on the inner upper wall of the mating groove 101 and at the outer edge of the connecting mating portion 12, a plurality of convex positioning blocks 110 are provided. Corresponding to this, on the upper end face of the adjusting column 31 of the connection, a connection channel 32 with an outward opening is provided, and on the inner side wall of the connection channel 32, a convex limiting platform 302 facing the center side of the adjusting column 31 is provided. During use, the connecting mating portion 12 is inserted onto the adjusting column 31 with the connection channel 32. It is set that the connecting mating portion 12 is extruded by the inner side wall of the connection channel 32, and the distance between the respective connecting mating portions 12 begins to decrease, thereby achieving the purpose of connection. At the same time, on the outer edge of the connection channel 32 on the upper end face of the adjusting column 31, a plurality of positioning openings 301 with an outward opening are provided, which are connected in cooperation with the positioning blocks 110 provided on the base body 1 to prevent the adjusting column 31 from rotating inside the mating groove 101. Moreover, the end face of the limiting platform 302 forms an inclined end face, and the connecting mating portion 12 is arranged inside the mating groove 101 and its end forms a convex fixing portion 102. When the connecting mating portion 12 continuously moves inside the connection channel 32 to the lower side of the limiting platform 302 and loses a certain constraint, the distance between the respective connecting mating portions 12 begins to increase, and the formed fixing portion 102 and the formed limiting platform 302 mutually restrict each other to prevent the distance between the base body 1 and the receiving base 30 from changing during use.

[0040] Specifically, an adjusting assembly is provided between the adjusting member 4 and the contact with the limiting base 3. The adjusting assembly includes an adjusting dial 40. The adjusting dial 40 is at least one group and is arranged on the outer side wall of the adjusting member 4. An opening 42 is formed on the end face of the formed adjusting member 4 and is directly sleeved on the adjusting column 31. To facilitate the control of the adjusting member 4, the adjusting dial 40 extending and provided on the outer side wall of the adjusting member 4 is toggled, so that the adjusting member 4 can freely rotate on the adjusting column 31. At this time, an adjusting rolling groove 43 is opened on the side end face of the adjusting member 4 close to the limiting base 3, and an adjusting ball 5 is connected in a rolling manner at the opening.

[0041] Support grooves 33, with multiple groups of said support grooves 33 being circumferentially distributed and provided on the upper end surface of the receiving base 30. An activity groove 34 is provided between two adjacent said support grooves 33. Moreover, the depth of the said activity groove 34 is set to be greater than the depth of the support groove 33. During use, the adjusted dial 40 being toggled drives the adjustment ball 5 to move on the end surface of the receiving base 30. When the ball is inside the support groove 33, the distance between the base body 1 and the receiving base 30 is the largest, and the moving rollers 2 provided on the base body 1 are no longer in contact with the supporting ground; when the adjustment ball 5 is inside the activity groove 34, the distance between the base body 1 and the receiving base 30 is the smallest, and the moving rollers 2 provided on the base body 1 are in contact with the supporting ground, achieving the purpose of making the base movable. Furthermore, one end of the formed activity groove 34 has a greater depth than the other end, and the depth difference formed inside the entire groove facilitates toggling the adjusted dial 40 to drive the adjustment ball 5 on the adjustment member 4 to transition from the end with a smaller depth to the support groove 33.

[0042] Refer to Figure 9 Specifically, the adjusting column 31 and the adjusting member 4 are in threaded connection. During use, the formed connection and cooperation portion 12 is connected to the adjusting column 31, and the adjusting member 4 and the adjusting column 31 are in threaded connection at the connection between the two. By controlling the rotation of the adjusting member 4 on the adjusting column 31, when the adjusting member 4 rotates and continuously approaches the interaction with the lower end surface of the base body 1, the adjusting column 31 can be made to move on the connection and cooperation portion 12, causing the limiting base 3 to move away from the base body 1 until the limiting base 3 comes into contact with the ground, making the moving rollers 2 move away from the ground, and the limiting base 3 then serves as the final receiving base body. Conversely, when the adjusting member 4 rotates and continuously moves away from the lower end surface of the base body 1, the adjusting column 31 can be made to move on the connection and cooperation portion 12, causing the limiting base 3 to approach the base body 1, making the moving rollers 2 contact the ground, achieving the purpose of moving the base.
