Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only illustrative and should not be construed as imposing any limitation on the scope of the present invention.

The embodiment of the application provides a lifting table cantilever fixing structure 1 which can be applied to scenes such as a learning table with a movable table top shown in figure 1. This lift table cantilever fixed knot constructs 1 includes fixing base, cantilever, bolt and nut, wherein, has seted up waist shape pilot hole on the fixing base, has seted up circular pilot hole on the cantilever, and the bolt passes waist shape pilot hole and circular pilot hole and is connected fixing base and cantilever, and the nut is twisted soon on the bolt. The cross-sectional shape of the bolt is matched with the kidney-shaped assembly hole, namely the cross section is also kidney-shaped as shown in figure 5, so that the rotation of the bolt can be limited, and the follow-up rotation of the bolt when the structure rotates is prevented. The circular assembling hole is circumscribed on the cross section of the bolt, so that the cantilever can rotate, the two sides of the hole are tightly matched with the bolt, and the assembling relation among the fixed seat, the bolt and the cantilever can refer to fig. 6. The structure reduces the processing difficulty of the bolt and the hole (reduces the precision requirements on the position and the size), and is more convenient to assemble.

A kidney-shaped hole refers to a hole similar to a kidney shape comprising two oppositely arranged circular arc edges. For the convenience of processing, in the present embodiment, the kidney-shaped hole is composed of two parallel straight sides and two opposite semicircular sides, as shown by a kidney-shaped fitting hole 2a in fig. 4.

In order to ensure that the cantilever is fixed in position and can move smoothly, POM gaskets can be arranged on the contact surfaces of the two sides of the cantilever, namely the POM gaskets are arranged between the cantilever and the fixed seat, and the POM gaskets are also arranged between the cantilever and a nut or a nut of the bolt.

As shown in fig. 2 to 6, in the present embodiment, the cantilever includes an inner cantilever 3 and an outer cantilever 4, the inner cantilever 3 is disposed inside the fixing base 2, and the outer cantilever 4 is disposed outside the fixing base 2.
