[0002] Existing office desks usually have a small threading hole on the corner of the desk. When users need to get electricity, they insert the plug into the threading hole and insert the plug into the electrical point under the desk. The space under the desk is small, and users need to squat and crawl under the desk to operate, which is time-consuming and laborious. In addition, if the keyboard and mouse cables are all passed through the threading hole, it is very troublesome to thread and remove the plugs. In addition, the electrical wires and network cables are messy under the desk, which poses certain safety hazards, especially the wires on the computer host. Users' feet often kick them, which may cause the computer to shut down abnormally, causing unnecessary trouble. Summary of the invention
[0003] In order to solve the above problems, the purpose of the utility model is to provide a center beam assembly structure. By hingedly arranging a flap on the center beam, the user can open the flap to get electricity, which is very convenient, and the threading position area is large, and it is very convenient to take and put the wires. In addition, a wire box is arranged under the center beam, which can effectively organize the wires and prevent users from kicking the wires. The purpose of the utility model is to provide an office desk with the above-mentioned center beam assembly structure.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:
[0005] A center beam assembly structure includes two cross beams and a center beam installed between the two cross beams, and a potential taking device is arranged under the center beam; the characteristic is that a flap is hinged on at least one side of the front and rear sides of the center beam, and the flap can rotate relative to the center beam along its hinged end so that the flap can cover or open the space between the two sides of the center beam and the table top.
[0006] In the above technical solution, a flap is hingedly provided on at least one side of the front and rear sides of the center beam, and the flap is located between the table top and the center beam. After opening the flap, the space between the two sides of the center beam and the table top is opened, and the potential is exposed. Users can quickly and easily get electricity on the table top, which is very convenient.
[0007] Preferably, the flap is formed with a first retaining wall below the hinged end, and when the flap is closed over the space, the first retaining wall of the flap abuts against the front side wall or the rear side wall of the middle beam. In this technical solution, after the flap covers the space, it can firmly support the front side wall or the rear side wall of the middle beam and is not easy to loosen.
[0008] Preferably, the front and rear sides of the center beam are provided with flap grooves extending along the length direction, and at least one side of the flap groove extends through the side of the center beam; the flap is provided with a hinge shaft arranged along its length direction, and after the hinge shaft is pushed into the flap groove from the side of the center beam, it can interact along the flap groove and can rotate relative to the flap groove. In this technical solution, the hinge shaft can be pushed into the flap groove from the side of the center beam, which is very convenient to assemble, and the hinge shaft can rotate relative to the flap groove, thereby allowing the flap to rotate relative to the flap groove to open the space between the table top and the center beam.
[0009] Preferably, a table plate groove for inserting a fixed plate is provided below the flap groove; a flexible buffer rod is also detachably provided in the table plate groove, and the flexible buffer rod extends into the flipping path of the flap. In this technical solution, the provision of the flexible buffer rod enables the user to close the flap without holding the flap by hand, and the flap falls slowly with the assistance of the flexible buffer rod, which is very convenient. It should be noted here that when the flap is arranged on the center beam, a flexible buffer rod is provided in the table plate groove; if the fixed plate (i.e., the table plate) is directly arranged on the center beam, the upper end of the fixed plate is flush with the upper end of the flap groove, the flap groove is blocked by the fixed plate, and the usable area on the fixed plate is larger. These two assembly methods are for users to choose according to their needs, with more choices and more humane.
[0010] Preferably, the flap is provided with a second retaining wall above the hinged end, and an extension portion is provided on the front and rear sides of the center beam in the front and rear directions; when the flap is in a completely opened state relative to the center beam, the second retaining wall of the flap is flipped over to be erected above the extension portion. In this technical solution, the second retaining wall of the flap is flipped over to be erected above the extension portion, so that when the flap is in a completely opened state relative to the center beam, it can be in an upright state and press on the extension portion to prevent the flap from further rotating.

[0012] When the flap cover is closed on the space, the curved rod abuts against the bottom wall of the flap groove so that the first retaining wall of the flap abuts against the front side wall or the rear side wall of the middle beam;
[0013] The round rod and the curved rod rotate in the flap groove, and the second retaining wall turns over to avoid the outer end of the extension part and is erected above the extension part, so that the flap is in an open state relative to the middle beam.
[0014] In the above technical solution, the hinge shaft includes a connected round rod and a curved rod, and one end of the curved rod is connected between the first retaining wall and the second retaining wall, and both rotate in the flap groove.
[0015] An angle is formed between the bent rod and the first baffle wall, and the angle is matched with the end angle of the front side wall or the rear side wall of the center beam. Therefore, after the bent rod abuts against the bottom wall of the flap groove, the first baffle wall abuts against the front side wall or the rear side wall of the center beam; the second baffle wall presents an inwardly concave avoidance arc surface so that when the flap opens the space, the avoidance arc surface bypasses the end angle of the extension part and is erected on the upper end of the extension part. At this time, the surface of the bent rod is matched with the end angle of the extension part.
[0016] Preferably, the upper end of the middle beam is constructed with an assembly groove with an upper end opening along the length direction, and at least one clamping member is clamped in the assembly groove; the clamping member includes a connecting section and flaps formed on both sides of the connecting section, and the flaps on both sides can be folded forward and backward relative to the connecting section to form a clamping groove between the two; when the clamping member is installed in the assembly groove, the outer wall surface of the flap of the clamping member abuts against the inner wall of the assembly groove, and the lower end of the screen is inserted into the clamping groove of the clamping member; the front and back sides of the flap are different, and when the flap is installed in the assembly groove in the forward folding state and the reverse folding state, the clamping member presents clamping grooves of different calibers. In this technical solution, the clamping member is installed in the assembly groove, and the front and back sides of the flap on the clamping member are folded to form a clamping groove of the same caliber, and the lower end of the screen is inserted into the clamping groove to achieve a tight fit, so the clamping member can adapt to screens of different sizes, has a wide range of applications, and can reduce the cost of accessory production.
[0017] Preferably, the connecting section includes a plurality of connecting blocks arranged at intervals, the flap includes a connecting vertical block hinged to the connecting block and a tight-fitting vertical block formed between adjacent connecting vertical blocks, the tight-fitting vertical block is constructed to protrude outward relative to the connecting vertical block, and the outer end surfaces of the plurality of connecting vertical blocks and the tight-fitting vertical block respectively form the two sides of the flap; the side wall of the assembly groove is constructed with a plurality of slide grooves, and the outer surface of the tight-fitting vertical block is formed with a plurality of sliders matched with the plurality of slide grooves; the upper parts of the connecting vertical block and the tight-fitting vertical block are formed with guide slopes facing each other. In this technical solution, the connecting vertical block and the tight-fitting vertical block are staggered, the structure is stable, and the material cost is reduced; when the slider on the tight-fitting vertical block matches with the slide groove of the assembly groove, the slot diameter is large and can be adapted to screens with larger thickness; when the outer wall of the connecting vertical block abuts against the outer wall of the slide groove, the slot diameter is relatively small and can be adapted to screens with relatively small thickness.
[0018] Preferably, a wire-threading box is fixedly provided at the lower end of the middle beam, and a sliding groove with an opening facing downward is provided at the lower end of the middle beam; installation slopes are constructed on both sides of the upper part of the wire-threading box, and the potential-taking device is installed on the installation slopes, or the potential-taking device is slidingly provided on the sliding groove.
