The assembling process and disassembling process of the assembled desk assembly 11 will be described in detail below.

As shown in fig. 2, since any two of the split desks 10 for the university class are spliced in the same manner, only the splicing process and the disassembling process of two of the split desks for the university class (the split desk 10 for the university class and the split desk 10' for the university class) of the split desk assembly 11 will be described below.

The splicing process of the spliced desk 10 for the university class and the spliced desk 10' for the university class is as follows:

as shown in fig. 6, before splicing, the tension spring 130 indirectly provides an elastic restoring force to the hemispherical lock portion 133 through the connecting portion 132, so that the stop 1331 protrudes out of the hemispherical avoiding groove 122 when the hemispherical lock portion 133 is reset; the tension spring 130 'indirectly provides elastic restoring force for the hemispherical locking portion 133' through the connection portion 132 ', so that the stop block 1331' protrudes out of the hemispherical avoiding groove 122 'when the hemispherical locking portion 133' is reset;

as shown in fig. 6, at the time of splicing, first, external forces are applied to the spliced desk 10 for a university class and the spliced desk 10 'for a university class, respectively, so that the spliced desk 10 for a university class and the spliced desk 10' for a university class move in directions approaching each other; the external force F applied to the split joint type desk 10 for the university class is opposite to the external force F 'applied to the split joint type desk 10' for the university class;

as shown in fig. 6, when the split desk 10 for a university classroom and the split desk 10 ' for a university classroom are sufficiently close, the tapered protrusion 123 ' contacts the stopper 1331 and the tapered protrusion 123 ' pushes the stopper 1331; at this time, the hemispherical locking portion 133 rotates around the center of the hemispherical avoiding groove 122 until the hemispherical locking portion 133 is completely accommodated in the hemispherical avoiding groove 122; that is, the stop block 1331 is also completely received in the hemispherical avoiding groove 122; of course, when the hemispherical locking portion 133 rotates around the center of the hemispherical avoiding groove 122, the splicing locking member 130 rotates around the center of the hemispherical avoiding groove 122; the hemispherical avoiding groove 122 is provided with a first through groove 124, and the splicing body 120 is provided with a second through groove 125; the first through groove 124 and the second through groove 125 enable the splicing locking element 130 to smoothly rotate around the center of the hemispherical avoiding groove 122;

as shown in fig. 6, it should be noted that the contact between the stop block 1331 and the tapered protrusion 123 'is surface contact, and the surface contact makes the force applied by the tapered protrusion 123' to the stop block 1331 more uniform and smoother, so that the hemispherical locking portion 133 smoothly rotates around the center of the hemispherical avoiding groove 122, and the splicing process is smoother;

as shown in fig. 6, at the same time, the tapered protrusion 123 comes into contact with the stopper 1331 'and the tapered protrusion 123 pushes the stopper 1331'; at this time, the hemispherical locking portion 133 'rotates around the center of the hemispherical avoiding groove 122' until the hemispherical locking portion 133 'is completely received in the hemispherical avoiding groove 122'; that is, the stop block 1331 'is also completely received in the hemispherical avoiding groove 122'; of course, when the hemispherical locking portion 133 'rotates around the center of the hemispherical avoiding groove 122', the splicing locking member 130 'rotates around the center of the hemispherical avoiding groove 122'; the hemispherical avoiding groove 122 'is provided with a first through groove 124', and the splicing body 120 'is provided with a second through groove 125'; the first through groove 124 'and the second through groove 125' enable the splice locking element 130 'to smoothly rotate around the center of the hemispherical avoiding groove 122';

as shown in fig. 6, it should be noted that, at this time, the contact between the stop block 1331 'and the tapered protrusion 123 is surface contact, and the surface contact makes the force applied by the tapered protrusion 123 to the stop block 1331' more uniform and smoother, so that the hemispherical locking portion 133 'smoothly rotates around the center of the hemispherical avoiding groove 122', and the splicing process is smoother;

as shown in fig. 6, the tapered protrusion 123 ' continues to extend into the receiving cavity 121 under the action of the external force F ' until the tapered protrusion 123 ' completely passes over the stop 1331; at this time, the hemispherical avoiding groove 122 and the hemispherical avoiding groove 122' are spliced into a complete spherical structure; in this process, the tension spring 130 is gradually subjected to tensile deformation and has elastic restoring force;

as shown in fig. 6, at the same time, the conical protrusion 123 continues to extend into the receiving cavity 121 'under the action of the external force until the conical protrusion 123 completely passes over the stop 1331'; in this process, the extension spring 130' is gradually subjected to tensile deformation and has elastic restoring force;

as shown in fig. 7, then, the application of the external force to the split desk 10 for the university class and the split desk 10' for the university class is stopped; under the elastic restoring force of the tension spring 130, the hemispherical locking portion 133 is reset, so that the blocking piece 1331 protrudes out of the hemispherical escape groove 122; at this time, the blocking piece 1331 is accommodated in the hemispherical avoiding groove 122 ' and blocks the conical protrusion 123 ', so as to prevent the conical protrusion 123 ' from coming off the accommodating cavity 121, thereby realizing the locking of the desktop splicing device 110 and the desktop splicing device 110 ', i.e. realizing the splicing of the spliced desk 10 and the spliced desk 10 ' (as shown in fig. 1);

as shown in fig. 7, at the same time, the hemispherical lock 133 'is reset by the elastic restoring force of the tension spring 130', so that the stop 1331 'protrudes out of the hemispherical escape groove 122'; at this time, the blocking piece 1331 'is received in the hemispherical avoiding groove 122 and blocks the tapered protrusion 123, so as to prevent the tapered protrusion 123 from coming out of the receiving cavity 121', thereby further locking the desktop splicing device 110 and the desktop splicing device 110 ', and enabling the splicing of the spliced desk 10 for the university classroom and the spliced desk 10' for the university classroom to be firmer.

The disassembly process of the split desk 10 for university class and the split desk 10' for university class is as follows:

as shown in fig. 6, first, the hand-held portion 131 and the hand-held portion 131' are respectively pulled to rotate the hemispherical locking portion 133 around the center of the hemispherical escape groove 122 until the stop block 1331 is completely received in the hemispherical escape groove 122 again; at this time, the stopper 1331 no longer blocks the tapered protrusion 123';

as shown in fig. 6, of course, at the same time, the hemispherical locking portion 133 'rotates around the center of the hemispherical avoiding groove 122' until the stop block 1331 'is completely accommodated in the hemispherical avoiding groove 122' again; at this time, the stopper 1331' no longer blocks the tapered protrusion 123;

as shown in fig. 6, then, external forces are applied to the split type desk 10 for the university class and the split type desk 10 'for the university class, respectively, to move the split type desk 10 for the university class and the split type desk 10' for the university class in directions away from each other; at this time, the tapered protrusion 123' is smoothly removed from the receiving cavity 121; meanwhile, the conical protrusion 123 is smoothly removed from the receiving cavity 121'; thereby realizing the disassembly of the splicing type desk 10 used for the university classroom and the splicing type desk 10' used for the university classroom.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
