Description

Technical Field

[0001] This utility model relates to the field of horizontal adjustment of machinery and equipment, and more particularly to a foot base with a reasonable structural improvement. Background Technology

[0002] Typically, four feet are arranged in a set. This set of feet is mounted on the bottom of a machine or piece of equipment, thus contacting a supporting surface, such as the ground. In this way, the set of feet can adjust the level of the machine or equipment on that supporting surface.

[0003] like Figure 6 As shown, the foot 80 has a joint that allows a bolt 81 to be connected to a base 90 and rotated flexibly. The bolt 81 has a polygonal portion 82 that receives a torque to tighten or loosen the bolt 81.

[0004] The joint includes: a neck 83, a ball 84, a joint 91, a socket 92, and a pre-reduced diameter portion 93. The neck 83 extends outward from the surface of the ball 84 and connects to the polygonal portion 82, making the ball 84 integral with the bolt 81. The joint 91 protrudes from the center of the top of the base 90. The socket 92 is recessed into the joint 91 to a depth facing the base 90. The diameter of the socket 92 is slightly larger than the diameter of the ball 84, and the depth of the socket 92 is less than the diameter of the ball 84. The pre-reduced diameter portion 93 at the free end of the joint 91 reduces the diameter of the opening of the socket 92 on its inner side.

[0005] The term "pre-production" here is short for "early manufacturing." Simply put, the tapered section is manufactured first, and the joint assembly takes place later.

[0006] During assembly, the ball 84 must squeeze into the pre-reduced diameter portion 93 to penetrate the ball socket 92, allowing the bolt 81 to engage with the base 90, thus completing the assembly of the foot 80. The pre-reduced diameter portion 93 does not interfere with the relative rotation of the ball 84 and the base 90, allowing the foot 80 to rotate freely. The diameter of the pre-reduced diameter portion 93 is crucial for the ball 84's engagement with the ball socket 92. If the diameter of the pre-reduced diameter portion 93 is too small, the ball 84 will not easily squeeze into the ball socket 92. Conversely, if the diameter of the pre-reduced diameter portion 93 is too large, the ball 84 can easily squeeze into the ball socket 92 and then easily detach.

[0007] Furthermore, the reduced diameter portion 93 restricts the depth of the ball socket 92, affecting the height of the joint 91. Not only is the reduced diameter portion 93 further away from the neck 83, causing the ball socket 92 to potentially receive approximately 3 / 5 of the volume of the ball 84, but the bolt 81 moves relative to the base 90 with an excessive swing 94 from the solid line position to the dashed line position, potentially contributing to the weight of the machine or equipment, causing it to crush or damage the foot 80.

[0008] Therefore, how to improve the joint structure of the foot seat has become an urgent problem to be overcome in this invention. Utility Model Content

[0009] In view of this, the main purpose of this utility model is to provide an improved foot structure, which adopts a post-fabrication method, forming a reduced diameter section after the ball enters the ball socket, thus improving the flexible joint structure. This not only solves the problem of easy detachment in the previous technology, but also overcomes the drawback of excessive swing amplitude.

[0010] To achieve the above objectives, this utility model provides an improved foot structure, comprising: a bolt; a ball integrally formed with the bolt; a base; a joint portion raised on the base; and a ball socket facing the base and formed within the joint portion.

[0011] After the ball is placed into the socket, a post-reduction diameter section is formed at the top of the joint. This post-reduction diameter section reduces the diameter of the socket opening, which both prevents the ball from leaving the joint and does not interfere with the rotation of the bolt and the base.

[0012] Preferably, the foot also includes a neck that extends outward from the surface of the ball and connects the ball to one end of the bolt.

[0013] Preferably, the post-reduced diameter portion is located near the neck, and the ball socket receives 1 / 2 to 4 / 5 of the ball.

[0014] This invention employs a post-processing method, forming a reduced-diameter section after the ball enters the socket, thus improving the flexible joint structure. This not only solves the problem of easy detachment in existing technologies but also overcomes the drawback of excessive swing amplitude.

Detailed Implementation

[0023] Next, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar structures or units. It is to be understood that the described embodiments are merely examples of some aspects of the present invention, and not all embodiments. Other embodiments can be deduced based on the described examples, or modifications and variations may be made as needed, all of which fall within the scope of protection of the present invention.

[0024] In the following description, directional terms such as "up," "down," "left," "right," "front," "back," "inner," "outer," and "side" are used only for reference to the directions in the accompanying drawings. The use of directional terms is for the purpose of better and clearer description and understanding of this utility model, and does not imply that the described device or element must have a specific orientation, structure, or operation, and therefore should not be construed as a limitation on the technical content of this utility model.

[0025] Unless specifically and explicitly stated otherwise, in the following description, "installed," "connected," "attached," or "on" should be interpreted broadly, including, for example, fixed connection, detachable connection, integral connection, mechanical connection, direct connection, indirect connection, or connection between two components. Those skilled in the art will understand the specific meaning of these terms in the various embodiments and even in the context of this invention based on ordinary knowledge or experience.

[0026] Unless otherwise stated, in the following description, "multiple" means two or more.

[0027] This utility model provides an improved foot structure, comprising: a bolt; a ball integrally formed with the bolt; a base; a joint portion raised on the base; and a ball socket facing the base and formed within the joint portion;

[0028] After the ball is placed into the socket, a post-reduction section is formed at the top of the joint. The post-reduction section reduces the diameter of the socket opening, preventing the ball from leaving the joint and not interfering with the rotation of the bolt and the base.

[0029] The improved foot structure of this utility model further includes: a neck that extends outward from the surface of the ball, the neck connecting the ball to one end of the bolt.

[0030] The reduced diameter portion is located near the neck, and the ball socket receives 1 / 2 to 4 / 5 of the ball.

[0031] like Figure 1 As shown in the preferred embodiment of the present invention, a foot base semi-finished product 100 includes: a nut 10, a bolt 20 and a base 30.

[0032] The bolt 20 has multiple external threads 22 on its outer side. The bolt 20 passes through the bottom of a machine or piece of equipment (not shown), allowing the external threads 22 to lock onto the multiple internal threads 12 on the inner side of the nut 10. The nut 10 can be removed from the bolt 20.

[0033] The bolt 20 forms a polygonal portion 24, a neck section 26, and a sphere 28. In this embodiment, the polygonal portion 24 is a hexagon, with a virtual diagonal line perpendicular to or intersecting a virtual center line 37 passing through the center of the bolt 20 (see...). Figure 5 (As shown). A user (not shown) uses a tool (e.g., a wrench) to twist the polygonal part 24, outputting a torque to the bolt 20, which can tighten or loosen the nut 10.

[0034] like Figure 5 As shown, along one diameter of the sphere 28, the neck 26 extends outward from the surface of the sphere 28. The neck 26 connects to the polygon 24, making the sphere 28 and the bolt 20 integral. The sphere 28 and the neck 26 are located on the centerline 37. The diameter of the sphere 28 is larger than the diameter of the neck 26, but smaller than a distance diagonally opposite the polygon 24.

[0035] Please refer to the following: Figure 1As shown, the base 30 is a disk, with one bottom surface 34 of the disk contacting a supporting surface, such as the ground. Above the base 30 is a conical surface 32, with a joint 36 raised in the middle of the conical surface 32. A ball socket 31 is recessed into the top 38 of the joint 36, facing the base 30. The diameter of the ball socket 31 is larger than the diameter of the ball 28, and the depth of the ball socket 31 is smaller than the diameter of the ball 28.

[0036] like Figure 2 As shown, in this embodiment, the joint 36 has no reduced diameter, and therefore there is no structural obstruction. The ball 28 extends into the joint 36 through an opening in the ball socket 31, so that the bolt 20 cooperates with the base 30 to form the foot semi-finished product 100.

[0037] like Figure 3 As shown, after assembly, the joint 36 deforms. The deformation referred to here is that the top of the joint 36 is squeezed towards the center, thereby forming a post-reduced diameter portion 33. This post-reduced diameter portion 33 is the key to the ball 28 joining the socket 31, allowing the bolt 20 to cooperate with the base 30 to form a foot 102.

[0038] like Figure 4 As shown, the reduced diameter portion 33 reduces the diameter of the opening of the ball socket 31, and the ball 28 is prevented from leaving the joint portion 36 by the reduced diameter portion 33. In this way, the ball 28, together with the ball socket 31 of the joint portion 36, and the neck 26 and the reduced diameter portion 33 are assembled into a joint.

[0039] The term "post-processing" is short for "post-production manufacturing." In other words, the preliminary work of the sphere 28 entering the sphere socket 31 is completed first, and then the finishing work of the diameter reduction section is performed.

[0040] This "post-processing" method improves the mechanical structure of the joint. The visible change is that the post-processed reduced diameter portion 33 is closer to the neck 26, and the joint portion 36 has an increased height, relatively increasing the depth of the ball socket 31. In this embodiment, the ball socket 31 may receive approximately 4 / 5 of the volume of the ball 28.

[0041] like Figure 5 As shown, the joint does not interfere with the relative rotation of the ball 28 and the base 30, allowing the foot 102 to rotate flexibly. For example, from an upright position to an inclined position, the bolt 20 moves relative to the base 30 by an angle 35. This angle 35 lies between the two center lines 37, indicating that the amplitude of the bolt 20's swing is small enough to overcome the problem of the foot 102 being crushed or damaged by the machine or equipment.

[0042] Without departing from the broad concept of this utility model, those skilled in the art will understand and modify the above-described embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed in the specification, and all modifications made in accordance with the spirit and technical scope of this utility model should be covered and protected by the scope of protection defined by this utility model.
