The joint structure performs the angle adjustment operation of the foot, and can also adapt to the uneven supporting surface, helping the machine or equipment to achieve a sense of balance.

Description

Foot joint structure

This creation is about the field of high support, especially the joint structure of a foot seat.

The known foot stand is arranged at the bottom of a machine or equipment, and the foot stand supports the machine or equipment to be placed on a supporting surface, such as the ground.

Some supporting surfaces are uneven, causing the machinery or equipment to be slightly inclined, reducing the accuracy of the processed parts and affecting the quality of the product. Therefore, the height of some feet can be adjusted to relatively change the overall horizontal state, which helps the machine or equipment adapt to the uneven supporting surface and achieve a good sense of balance.

The creator of this case devoted manpower and material resources to the research and development of the feet, and achieved certain results, such as Taiwan's M587718 model patent case.

However, the creator of this case is not complacent, and continues to study the foot to create a joint structure. The main purpose is to use an articulated structure to allow the foot to perform angle adjustments, which can also adapt to uneven supporting surfaces. The machinery or equipment achieves a sense of balance.

To achieve the above purpose, the foot base of this creation includes: a support rod with a ball part; a base with a groove to receive the ball part of the support rod, and a groove is formed at the groove adjacent to the opening; and, a buckle The member is arranged in the groove to prevent the ball part from escaping from the groove through the opening, but does not interfere with the mutual rotation of the ball part and the base.

Wherein, the support rod has an external threaded section and a non-threaded section connected, and the ball part is a part of the non-threaded section. The non-threaded section also has a cylinder connecting the external threaded section and a hexagonal part. The cylinder is designed to integrate the externally threaded section and the hexagonal part. The diameter of the ball part is smaller than the diagonal distance of the hexagonal part. The non-threaded section also has a neck that connects the hexagonal portion and the ball portion together, and the diameter of the neck portion is smaller than the diameter of the ball portion.

In addition, the fastener is a C buckle.

In this way, the foot base of this creation uses fasteners to allow the ball to be combined with the groove of the base, thereby creating a joint structure. The joint structure performs the angle adjustment operation of the foot, and can also adapt to the uneven supporting surface, helping the machine or equipment to achieve a sense of balance.

In order to make the purpose, features, and advantages of this creation easy to understand, one or more embodiments are provided in conjunction with the attached drawings, and the detailed description is as follows.

As shown in Fig. 1, the preferred embodiment of the foot base 10 of the present invention can be disassembled or decomposed into a fastener 13, a supporting rod 20 and a base 30. In other words, the fastener 13 is combined with the support rod 20 and the base 30 to form the foot base 10.

In the figure, the two ends of the support rod 20 are defined as the connecting end 21 and the connecting end 22. An external threaded section 23 extends from the connecting end 21 and passes through a non-threaded section 24 to the connecting end 22. The non-threaded section 24 includes a cylinder 25, a hexagonal portion 26, a ball portion 27, and a neck 28 (refer to Figure 3). The cylinder 25 is designed to integrate the external threaded portion 23 and the hexagonal portion 26 into one body. The hexagonal portion 26 is connected to the ball portion 27 via the neck 28, and the center of the spherical surface of the ball portion 27 serves as the connecting end 22 of the support rod 20. The diameter of the neck portion 28 is smaller than the diameter of the ball portion 27, and the diameter of the ball portion 27 is smaller than the diagonal distance of the hexagonal portion 26.

Along the axis of the base 30, a groove 33 extends from the upper surface 31 to the lower surface 32 to a depth. The center of the upper surface 31 of the base 30 is the opening of the groove 33. The wall defining the groove 33 of the base 30 is a circumferential surface 35 (see Figure 3), and the circumferential surface 35 is connected to a cone in the depth of the groove 33. A surface 36 (see Fig. 3). The conical surface 36 makes the groove 33 have a closed bottom surface. The diameter of the circumferential surface 35 is larger than the diameter of the ball 27, a groove 34 is formed on the circumferential surface 35 adjacent to the opening of the groove 33, and the diameter of the groove 34 is larger than the diameter of the groove 33.

As shown in Figures 2 and 3, the fastener 13 is a C buckle in this embodiment, and the C buckle is reduced in diameter and enters the groove 33 through the opening. The fastener 13 falls on the groove 34 and returns to its original diameter. The wall of the groove 34 enclosed by the base 30 prevents the fastener 13 from falling off the bottom surface of the groove 33.

When combined, the joint end 22 of the support rod 20 passes through the fastener 13 and enters the groove 33 of the base 30 to form a joint structure. When the ball 27 passes through the opening of the groove 33, the inner diameter of the fastener 13 is smaller than the diameter of the ball 27, and the ball 27 expands the diameter of the fastener 13 and squeezes into the base 30. When the ball 27 reaches the bottom surface of the groove 33, the fastener 13 returns to its original diameter, preventing the ball 27 from leaving the groove 33 through the opening, but does not interfere with the mutual rotation of the ball 27 and the base 30.

In this way, the connecting end 21 of the support rod 20 passes through a nut 11, and an internal threaded hole 12 of the nut 11 is screwed to the external threaded section 23, and the foot 10 is installed on a machine or equipment (not shown). bottom. If necessary, the hexagonal portion 26 is covered by a tool (such as an open-end wrench), and the nut 11 and the external thread section 23 are used to perform the installation operation of the foot 10.

The ball 27 contacts the conical surface 36 of the groove 33, so the joint structure allows the support rod 20 to stand vertically on the base 30 under gravity. At this moment, the neck 28 supports the hexagonal portion 26 to maintain a distance from the upper surface 31 of the base 30. The lower surface 32 of the base 30 has a large area, so that the machine or equipment can be stably placed on a supporting surface, such as the ground.

In Figure 4, the joint structure allows the support rod 20 to swing to an angle 14 and maintain a tilted state relative to the base 30, helping the machine or equipment to adapt to uneven support surfaces.

Generally, the hexagonal portion 26 touches the upper surface 31 of the base 30, and represents the angle 14 at which the support rod 20 is inclined relative to the base 30, which is the maximum angle of the joint structure.
