In a possible implementation, as shown inanda first mounting portionis disposed on the first beam, at least two second mounting portionsare disposed on the second beam, and the first mounting portionis configured to be connected to any one of the at least two second mounting portions.

The first beamand the second beamboth include a vertical main body. The first mounting portionand the second mounting portionsare respectively disposed on these vertical main bodies. During installation, the first mounting portionis aligned with and connected to one second mounting portion. A plurality of second mounting portionsare disposed on the second beam, allowing the first mounting portionto be able to be connected to different second mounting portions, which changes an overall length of the beam assemblyto achieve the purpose of the telescopic desk frame of being extendable and retractable. As shown inandthe first mounting portionincludes two first holesand the second mounting portionincludes two second holesA spacing between the two first holesis equal to a spacing between the two second holes

During installation, the first mounting portionand the second mounting portionfit together, allowing the two first holesto be aligned with the two second holesrespectively. This alignment facilitates connection, ensuring that the first mounting portionand the second mounting portionhave multiple bearing points when bearing weight, thereby enhancing the stability of the connection between the first beamand the second beam. Additionally, the spacing between the two first holesof the first mounting portionis equal to the spacing between the two second holesof the second mounting portion, ensuring that the first mounting portionand the second mounting portioncan connect and cooperate with each other.

In some embodiments, the first mounting portion is connected to the second mounting portion by an installation fastener configured to be inserted into the first hole and the second hole corresponding to the first hole. The installation fastener can be of various types. For example, the first mounting portionand the second mounting portioncan be connected by at least one of a bolt, strap, or buckle.

Specifically, the first mounting portionbeing connected to the second mounting portionby the installation fastener can achieve a detachable effect of the first mounting portionof being detachably connected to different second mounting portions. Therefore, the installation fastener can be disassembled and reinstalled according to different needs, achieving the telescopic effect of the telescopic desk frame. Moreover, the installation fastener allows the connection to have excellent load-bearing capacity, making the connection between the first beamand the second beammore stable, thereby enhancing the stability of the beam assembly.

As shown in-, the telescopic desk frame further includes a protruding portion disposed at least on a top surface of the first upper flange, where the top surface of the first upper flange is lower than a top surface of the second upper flange. In some embodiments, the protruding portion can be at least one of a desk mat, a raised hole, or a raised block, and a plurality of protruding portions of different heights can be positioned at any part on a surface where the telescopic desk frame contacts the desk board. For example, the plurality of protruding portions of different heights can be disposed on both the top surface of the first upper flange and the top surface of the second upper flange, or the plurality of protruding portions of different heights can be disposed only on a top surface with a lower altitude of the first upper flange and the second upper flange.

At least two beam assemblies are arranged parallel, and two ends of each beam assembly are connected with the two desk leg assemblies respectively.

The telescopic desk frame further includes two supporting portions, where the two supporting portions are arranged respectively to the two desk leg assemblies.

Each supporting portion includes a first supporting plate, the first supporting plate is arranged horizontally and protrudes in an extension direction of the beam assembly, and a connection hole configured to be connected with a desk board is disposed on the first supporting plate.

In a possible implementation, as shown in,, and, a top surface of the first upper flangeis lower than a top surface of the second upper flangeand a first raised holeis disposed on the first upper flangeAdditionally, a second protruding holecan be disposed on the top surface of the second upper flangeor not.

With the first beamconnected to the second beam, the first beamis positioned below the second beam, creating a height difference between them, while the first upper flangeof the first beamand the second upper flangeof the second beamboth need to contact the desk board. Therefore, a top surface of the first raised holecan share a same altitude with a top surface of the second raised holeor the top surface of the second upper flangeallowing the end of the telescopic desk frame that contacts the desk board to be on the same horizontal plane, which ensures that when the desk board is connected to the telescopic desk frame, the desk board can be supported reposefully.

Two beam assemblies are arranged parallel and connected with and between the two desk leg assemblies, and two ends of each beam assembly are connected with the two desk leg assemblies respectively.

The presence of two beam assemblies between the two desk leg assembliesmakes a structure of the telescopic desk frame more stable and also allows the desk board to be installed on the telescopic desk frame more stably.
