[0024] Embodiment one:

[0025] The embodiment provides a wheel body connecting seat.

[0026] As Figure 1 shown, a wheel body connecting seat is composed of a body, the body includes a sleeve 1 and a connecting plate 2 which are independently machined, the outer wall of the sleeve 1 is attached to the end face of the connecting plate 2 and is welded and fixed, so that the relative position between the sleeve 1 and the connecting plate 2 is fixed. The sleeve 1 and the connecting plate 2 are independently machined and are fixed by welding after assembly, compared with the original integrated casting method, it not only effectively simplifies the processing procedure and facilitates processing, but also ensures production safety, is conducive to environmental protection, can also improve the quality of products, prevents the increase of scrap rate due to casting defects, and effectively improves the use experience.

[0027] In production, first, the independent sleeve 1 and the connecting plate 2 are formed by machining, then the end face of the connecting plate 2 is abutted on the outer wall of the sleeve 1 and a welding groove 4 is formed, then welding is carried out along the welding groove 4 and a welding seam is formed, the welding seam is located in the welding groove 4 and is tightly connected with the inclined surface 3 and the outer wall of the sleeve 1 respectively, finally, the reinforcing plate 7 is installed on the connecting plate 2, the bottom edge of the reinforcing plate 7 is welded and fixed with the top surface of the horizontal part 6, and the side edge is welded and fixed with the side wall of the vertical part 5 (as Figure 2 shown).

[0028] The sleeve 1, the connecting plate 2 and the reinforcing plate 7 are obtained by machining and the wheel body connecting seat is formed by welding, compared with the integrated casting processing method, it has the characteristics of small equipment cost, safety and small pollution, effectively improves the safety and reliability, and can ensure the product quality, effectively solves the problem of uncontrollable quality during casting, and then improves the product quality by reducing the scrap rate and reduces the production cost.

[0029] In the embodiment, the two side edges of the end face are provided with inclined surfaces 3, when the end face is attached to the outer wall of the sleeve 1, the inclined surfaces 3 and the outer wall of the sleeve 1 form a welding groove 4 (as Figure 3 shown) which is open outward. The inclined surfaces 3 are arranged along the edges of the end face, so that the width of the end face is less than the thickness of the vertical part 5, which facilitates the matching and attachment of the end face and the outer wall of the sleeve 1, and also forms the welding groove 4 by using the inclined surfaces 3 and the outer wall of the sleeve 1, and then improves the welding reliability by increasing the contact area between the welding seam and the groove wall of the welding groove 4, and improves the connection strength between them. The opening angle of the welding groove 4 is less than 90 degrees, which plays a converging role on the hot melt metal formed by welding, effectively increases the contact area between the welding seam and the outer wall of the sleeve 1 and the vertical part 5 without increasing the welding workload.

[0030] In this embodiment, the end edge of the connecting plate 2 is arranged in the same direction as the axis of the sleeve 1. The end edge of the connecting plate 2 is attached to the outer wall of the sleeve 1 along the axial direction of the sleeve 1 to increase the contact length between the end edge of the connecting plate 2 and the sleeve 1. The length of the sleeve 1 is greater than the length of the end edge of the connecting plate 2, so that the end face can be completely attached to the outer wall of the sleeve 1. The vertical part 5 is located in the same plane as the axis of the sleeve 1, which not only ensures that the end face of the connecting plate 2 matches and fits the outer wall of the sleeve, but also ensures that the weld grooves 4 on both sides of the end face have the same cross-sectional profile, thereby ensuring that the welds on both sides have the same structural strength.

[0031] In this embodiment, the connecting plate 2 has an L-shaped cross-section, including a vertical portion 5 welded to the sleeve 1 and a horizontal portion 6 formed by bending the end of the vertical portion 5 away from the sleeve 1. The body includes a reinforcing plate 7 disposed on the connecting plate 2, the reinforcing plate 7 being disposed on the side of the vertical portion 5 facing the horizontal portion 6. The reinforcing plate 7 is in the shape of a right-angled triangle, the bottom edge of the reinforcing plate 7 is attached and fixed to the top surface of the horizontal portion 6, and the side edge is attached and fixed to the side wall of the vertical portion 5, providing support and positioning for the vertical portion 5 and the horizontal portion 6, ensuring that the connecting plate 2 always maintains an L-shape, thereby ensuring that the relative positions between the roller connected to the sleeve 1 and the pedal connected to the horizontal portion 6 are fixed.

[0032] In this embodiment, the horizontal portion 6 is provided with a plurality of mounting holes 8 arranged in a straight line. The number of mounting holes 8 is multiple, preferably three, which effectively simplifies the structure and improves connection reliability by increasing the number of mounting holes 8.

[0033] In this embodiment, a reinforcing rib 9 is provided at the junction of the horizontal part 6 and the vertical part 5. The reinforcing rib 9 is arranged perpendicular to the junction line of the horizontal part 6 and the vertical part 5, so that the two ends of the reinforcing rib 9 are respectively arranged on the horizontal part 6 and the vertical part 5, which effectively improves the resistance to deformation of the connecting plate 2.

[0034] In this embodiment, a keyway 10 is provided on the periphery of the end of the sleeve 1, which facilitates the insertion and fixing of the rotating shaft, and also effectively restricts the rotation of the rotating shaft relative to the sleeve 1, thereby improving the reliability of the connection between the roller and the sleeve 1.

[0035] Example 2:

The rollers are rotatably inserted into the sleeves 1 of the corresponding wheel connecting seats via a rotating shaft. The wheel connecting seats include a main wheel seat 13 and an auxiliary wheel seat 14 disposed at the front and rear edges of the pedal 12, respectively. The main wheel seat 13 and the auxiliary wheel seat 14 are connected to the track via corresponding rollers, keeping the pedal 12 in a horizontal position. The main wheel seat 13 receives external force and drives the pedal 12 to slide along the track.

[0038] In the embodiment, the wheel body connecting seat can be divided into the main wheel seat 13 and the auxiliary wheel seat 14 with partial functional differences according to the installation position and assembly requirement difference, the main wheel seat 13 and the auxiliary wheel seat 14 are both produced by the way of independent machining of the sleeve 1, the connecting plate 2 and the reinforcing plate 7 and welding fixation, which not only facilitates the batch production and improves the production efficiency, but also can obtain the corresponding function by configuring the parts with local differences, and should be regarded as the specific embodiment of the embodiment. Specifically, the reinforcing plate 7 of the main wheel seat 13 is provided with the avoiding groove 11 (as shown in the figure), the components adjacent to the main wheel seat 13 are avoided by setting the avoiding groove 11, which not only facilitates the installation of the main wheel seat 13, but also ensures that the main wheel seat 13 does not interfere with the adjacent components during use, and ensures the smooth running of the sidewalk.
