DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution for an office desk that is convenient for disassembly, assembly and transportation: it includes an office desk surface 1, support legs 2 and a support beam 3;

[0024] The support beam 3 is provided with supporting inclined beams 4 on both sides of the lower end of the supporting beam 3, and there are two supporting inclined beams 4, which are symmetrically distributed on both sides of the lower end of the supporting beam 3, and a supporting notch 5 is fixedly installed on the outer side of the lower bottom end of the supporting inclined beam 4, and the inner side of the supporting notch 5 is fitted and movably connected to the outer side wall of the middle part of the supporting leg 2, and the top ends of the two sides of the supporting beam 3 are fitted and movably connected to the inner side wall of the upper end of the supporting leg 2. There are two supporting legs 2, which are symmetrically distributed on the top ends of the two sides of the supporting beam 3. A first positioning pin hole 6 is opened through the upper end of the supporting leg 2, and the first positioning pin hole 6 penetrates inwardly to both sides of the upper end of the supporting beam 3. The first positioning pin holes 6 are symmetrically distributed on the upper ends of the supporting legs 2, and the inner walls of the first positioning pin holes 6 are fitted and movably connected with the first positioning pin columns 7. A connecting rod 8 is fixedly installed on the top end of the first positioning pin column 7, and a connecting spring 9 is fixedly installed on the inner side of the connecting rod 8, and the inner top end of the connecting spring 9 is fixedly installed on both sides of the upper end of the supporting beam 3, so that the connecting rod 8 is elastically connected through the connecting spring 9.

[0025] A limiting notch 10 is provided on the top of the support leg 2, and the inner wall of the limiting notch 10 is fitted and movably connected to the limiting block 11. A second positioning pin hole 12 is provided on the side wall of the top of the support leg 2, and the second positioning pin hole 12 passes through the limiting block 11. The desk surface 1 is fixedly installed on the top of the limiting block 11, and the inner wall of the second positioning pin hole 12 is fitted and movably connected with a second positioning pin column 13. The outer curved surface of the inner end of the second positioning pin column 13 is provided with an annular groove 14, and the inner wall of the annular groove 14 is fitted A conical limiting ring 15 is movably connected thereto, and the inner wall diameter of the conical limiting ring 15 is larger than the inner curved surface diameter of the annular groove 14, so that when the inner top end of the second positioning pin 13 passes through the inner wall of the second positioning pin hole 12, the conical limiting ring 15 will move downward along the inner wall of the annular groove 14 under the action of gravity, and the outer side of the lower end of the conical limiting ring 15 is movably connected to the inner wall of the upper top of the supporting leg 2, so that the second positioning pin 13 is limited by the conical limiting ring 15 and the annular groove 14.

[0026] Working principle: When the utility model is in use, when it is necessary to separate and disassemble the desk surface 1, the support leg 2 and the support beam 3, the connecting rod 8 is pulled outward. When the connecting rod 8 is pulled outward, the first positioning pin 7 is driven to move outward along the inner wall of the first positioning pin hole 6. When the first positioning pin 7 moves out of the inner wall of the first positioning pin hole 6, the support beam 3 is pushed to drive the support notch 5 to move out of the outer wall of the middle part of the support leg 2, so that the support beam 3 and the support leg 2 can be separated.

[0027] At the same time, by pushing the conical limiting ring 15 upward, when the conical limiting ring 15 is pushed upward, the conical limiting ring 15 will move upward along the inner wall of the annular groove 14, and when the conical limiting ring 15 moves upward, the conical limiting ring 15 will be hidden in the inner wall of the annular groove 14. When the conical limiting ring 15 is hidden in the inner wall of the annular groove 14, the second positioning pin 13 can be moved out of the inner wall of the second positioning pin hole 12 by pulling the second positioning pin 13 outward. When the second positioning pin 13 moves out of the inner wall of the second positioning pin hole 12, the limiting block 11 is driven to move out of the inner wall of the limiting notch 10 by pushing the office desk 1, so that the office desk 1 and the supporting leg 2 can be separated, thereby realizing the function of facilitating the disassembly of the office desk 1, the supporting leg 2 and the supporting crossbeam 3 without using tools;

[0028] When the desk surface 1, the supporting legs 2 and the supporting crossbeam 3 need to be installed, the limiting block 11 is reinserted into the inner wall of the limiting notch 10. When the limiting block 11 is inserted into the inner wall of the limiting notch 10, the second positioning pin 13 is inserted into the inner wall of the second positioning pin hole 12. When the second positioning pin 13 is inserted into the inner wall of the second positioning pin hole 12, the conical limiting ring 15 is pushed to hide in the inner wall of the annular groove 14 by the action of the conical outer surface of the conical limiting ring 15. When the conical limiting ring 15 is hidden in the inner wall of the annular groove 14, the inner top of the second positioning pin 13 can pass through the inner wall of the second positioning pin hole 12. When the inner top of the second positioning pin 13 passes through the inner wall of the second positioning pin hole 12, the conical limiting ring 15 will move downward along the inner wall of the annular groove 14 again under the action of gravity, so as to limit the second positioning pin 13. When the second positioning pin 13 is limited, the office table 1 can be installed and fixed between the support leg 2;

[0029] By re-attaching the support groove 5 to the outer wall of the middle part of the support leg 2, when the support groove 5 is re-attached to the outer wall of the middle part of the support leg 2, the connecting rod 8 is pulled outward so that the inner top end of the first positioning pin 7 is aligned with the opening of the first positioning pin hole 6. At the same time, when the connecting rod 8 is pulled outward, the connecting spring 9 will be stretched. Therefore, when the inner top end of the first positioning pin 7 is aligned with the opening of the first positioning pin hole 6, by releasing the force of pulling the connecting rod 8, the elastic potential energy generated by the stretching deformation of the connecting spring 9 will automatically drive the connecting rod 8 to move inward. When the connecting rod 8 moves inward, it will push the first positioning pin 7 to be reinserted into the inner wall of the first positioning pin hole 6, so that the support beam 3 is installed and fixed to the support leg 2, thereby realizing the overall function of facilitating the disassembly and assembly of the office desktop 1, the support leg 2 and the support beam 3 without the use of tools.
