[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 6 As shown, the slide rail assembly of this utility model includes a slide rail base 1, a slide rail base 1 having a slide groove 11 along its length, a pulley unit slidably connected in the slide groove 11, and a slide table 2 connected above the pulley unit.

[0032] like Figure 6 As shown in the preferred embodiment of this utility model, the pulley unit includes a pin 3, a sleeve 31 fitted onto the pin 3 with a clearance fit between the sleeve 31 and the pin 3, a pulley 32 fitted onto the sleeve 31 with a clearance fit between the pulley 32 and the sleeve 31, and a slide table 2 connected to the top of the pin 3. After the slide rail 1, the pulley unit, and the slide table 2 are assembled, the pulley unit can slide on the slide rail 1, driving the slide table 2 to move, thereby enabling the movement of certain components on the slide table 2, such as a camera or pan / tilt unit.

[0033] like Figure 2 and Figure 6 As shown, in a preferred embodiment of the present invention, a shim 33 is provided between the pulley 32 and the slide table 2. The shim 33 is sleeved on the shaft pin 3. The shim 33 is used to isolate the slide table 2 and the pulley 32, release the axial vertical degree of freedom, avoid the pulley 32 being completely constrained, and reduce the overall displacement and shaking of the slide rail assembly when it is in working state, thereby improving the stability and accuracy of the working process.

[0034] like Figure 6 As shown, in a preferred embodiment of the present invention, the shaft pin 3 is provided with positioning steps, which are divided into a primary positioning step 4 and a secondary positioning step 41. The bottom end of the bushing 31 is located at the primary positioning step 4, which is used to release the degree of freedom of the pulley 32 and realize the free rotation of the pulley 32. The pad 33 is located at the secondary positioning step 41, which is used to support the slide table 2 and realize the stable support of the slide table 2.
