The height adjustment of the main frame can be realized through the telescopic adjustment of the telescopic assembly.

The mainframe of the embodiment can be used for placing a computer host. For example, in the case of a desktop computer, the host computer is usually placed on the ground or on a desk, and the host computer is placed on the desk, which not only occupies the ground but also is easy to kick. Particularly, if the lifting table is used, the display is placed on the lifting table top, and the host machine and the display are connected through the cable, so that a great potential safety hazard exists in the lifting process of the lifting table. The main frame of the utility model can effectively solve the problems: the main frame is arranged at the bottom of the desktop, and then the computer host is arranged on the main frame, so that the computer host does not occupy the ground space and can lift along with the desktop.

The main frame of the utility model provides an embodiment of a telescopic assembly, which comprises a first telescopic main body 2, a second telescopic main body 1 and the adjustable locking device, wherein the first telescopic main body 2 is slidably sleeved on the outer wall of the second telescopic main body 1, the adjustable locking device is arranged between the first telescopic main body 2 and the second telescopic main body 1, and telescopic adjustment and locking between the first telescopic main body 2 and the second telescopic main body 1 are realized through the adjustable locking device.

When the telescopic assembly is applied to the computer host mounting frame, the first telescopic main body 2 is a bottom plate assembly, the second telescopic main body 1 is a top plate assembly, and the bottom plate assembly can be a transparent assembly. The bottom plate assembly is slidably sleeved on the outer wall of the top plate assembly, and locking and telescopic adjustment between the bottom plate assembly and the top plate assembly are achieved through the adjustable locking device. The adjustable locking mechanism in the telescopic assembly of the present invention is described in detail below.

As shown in fig. 1 to 3, the adjustable locking device of the present invention includes a cam handle 3 and a fixed block 4, the cam handle 3 is rotatably disposed on a bottom plate assembly, the cam handle 3 has an eccentric cam 5, a first end of the fixed block 4 contacts with a circumferential outer wall of the eccentric cam 5, a second end of the fixed block 4 contacts with a top plate assembly, and a second end of the fixed block 4 is opposite to the first end. By rotating the eccentric cam 5, different portions of the circumferential outer wall of the eccentric cam 5 are in contact with the fixed block 4. The fixing block plays a role in fixing the top plate assembly and the bottom plate assembly by means of the extrusion force of the eccentric cam in the cam handle. The fixing block can be made of nylon or POM material.

As shown in fig. 4, a functional groove 11 is formed in the fixed block 4 on a side facing the eccentric cam 5, and does not penetrate the fixed block 4. The functional groove 11 has an opening facing the eccentric cam 5, and an end surface of the opening of the functional groove 11 is in contact with a circumferential outer wall of the eccentric cam 5. The end surface of the opening of the functional groove 11 is recessed toward the center.

The cam handle 3 further comprises a rotating handle, and the rotating handle is fixedly connected with the circumferential outer wall of the eccentric cam 5. The adjustable locking device is arranged to adjust the extrusion force of the eccentric cam 5 to the fixed wheel 4 by rotating the rotating handle, so that the locking state and the telescopic adjusting state between the top plate assembly and the bottom plate assembly are realized.

Three through holes 6 with different sizes are arranged on the rotating handle of the utility model. The twist grip can be manufactured by a die-casting process, such as aluminum die-casting, which generally has a hardened surface and a softer inner surface. The through hole 6 is arranged on the rotating handle, the area of a hardening layer is large, and therefore the strength of the rotating handle can be increased to a certain extent.

As shown in fig. 2, the telescopic assembly further comprises a mounting bracket, the mounting bracket comprises at least two mounting lugs 7, the two mounting lugs 7 are vertically and fixedly connected with the outer wall of the bottom plate assembly, the two mounting lugs 7 are parallel to each other, and the eccentric cam 5 is hinged to the two mounting lugs 7 through a pin shaft.

When the rotating handle is rotated and adjusted, the fixed block 4 is not displaced in the telescopic direction of the bottom plate assembly and the top plate assembly under the limitation of the mounting through hole of the bottom plate assembly.

The fixed block is extruded in the mounting through hole to generate deformation and displacement, and the deformation is recovered when the extrusion force is reduced. The moving form of the fixed block after being extruded can be translational motion, irregular motion and the like. The shape of the fixed block is not limited, and the number of the fixed blocks can be one or more than two. The mounting through holes may be rectangular holes, or may be in other shapes, for example, circular arc holes, spline holes, or the like, and the number of the mounting through holes may be one or more than two.
