The first fastener is sequentially arranged on the second boss 12 and the pin 7 along the first direction and fastened on the pin 7. In the present embodiment, the first fastener is a first screw 5. A second groove 121 is arranged on the side of the second boss 12 facing away from the longitudinal beam 4. The head of the first screw 5 is located in the second recess 121. The pin 7 has a threaded hole corresponding to the threaded shaft of the first screw 5, and the threaded shaft of the first screw 5 is inserted through the second boss 12 and the pin 7 in this order and fastened to the pin 7. The head of the first screw 5 may be located between the first sidewall 31 and the second boss 12 of the cross member 3 to hide the first screw 5 within the connection structure, simplifying the appearance of the connection structure. Optionally, the first direction in which the first fastener is threaded is angled to the axial direction of the stringer 4.
In this embodiment, the second recess 121 is preferably a circular recess, and the first screw 5 is preferably an inner angle screw, and further preferably an inner hexagon screw. When the inner angle screw is adopted, a dismounting tool, such as an inner hexagonal wrench, can be conveniently placed at the head of the inner angle screw, and the longitudinal beam 4 and the second boss 12 are conveniently mounted and dismounted.
In practical applications, the first fastening member may also be other types of fastening members, such as an external angle screw, a connecting pin, etc., and the present disclosure is only given as a preferred embodiment, and the scope of the present disclosure is not limited thereto. The second boss 12 of the connecting device body correspondingly has a hole for the first fastening member to pass through, and the hole is preferably a hole with smooth inner wall and has a diameter equal to or slightly larger than the maximum outer diameter of the insertion part of the first fastening member, but not limited thereto.
The third boss 13 is disposed at a third end of the connecting device body, and the third boss 13 is tightly attached to the outside of the first sidewall 31 of the cross beam 3. The second fastener is sequentially arranged on the third boss 13 and the first side wall 31 of the cross beam 3 along the second direction and fastened on the outer wall of the cross beam 31. In this embodiment, the second fastener is a second screw 6. The third projection 13 is provided with a first recess 131 on the side facing away from the cross member 4. The head of the second screw 6 is located in the first recess 131. The threaded rod of the second screw 6 sequentially penetrates through the third boss 13 and the first side wall 31 of the cross beam 3 and is locked by a second nut 61. Optionally, the second direction in which the second fastener is threaded is at an angle to the axial direction of the stringer 4. In such an embodiment, since the second screws 6 are located below the connection of the longitudinal beams 4 and the cross beams 3, which is actually equivalent to the connection of the hidden second screws 6, a neat appearance of the connection structure is achieved.
Like the first fastener, in this embodiment, the first recess 131 is preferably a circular recess, and the second screw 6 is preferably an internal angle screw, and further preferably a socket head cap screw. In practical applications, the second fastening member may also be other types of fastening members, such as external angle screws, connecting pins, etc., and the present disclosure is only given as a preferred embodiment, and the scope of the present disclosure is not limited thereto. The third boss 13 of the connecting device body correspondingly has a hole for the second fastening member to pass through, and the hole is preferably a hole with smooth inner wall and has a diameter equal to or slightly larger than the maximum outer diameter of the insertion part of the second fastening member, but not limited thereto.
In this embodiment, a connection plate 33 is further provided inside the cross beam 3. One end of the connecting plate 33 abuts the first extension 111 of the first boss 11. The other end of the connection plate 33 is provided with a first connection hole 331 through which the second fastener passes, and a gap is provided between a portion of the connection plate 33 where the first connection hole 331 is provided and the first sidewall 31 of the cross beam 3. In this embodiment, the first bosses 11 and the third bosses 13 of the connecting device are further fastened together with the first side wall 31 and the second side wall 32 of the cross beam 3 by the arrangement of the connecting plates 33. Since there is a gap between the portion of the connection plate 33 where the first connection hole 331 is provided and the first sidewall 31 of the cross beam 3, the connection plate 33 may protect the first sidewall 31 of the cross beam 3 from being damaged. In addition, because the second direction that the second fastener wore to establish is at an angle with the axial direction of longeron 4, can be through the setting of connecting plate 33 for the fastening face of second fastener is perpendicular with the axial direction of second fastener, increases fastening effect. In the embodiment where the second fastening member is the second screw 6, the threaded rod of the second screw 6 sequentially passes through the third boss 13, the first sidewall 31 of the cross beam 3, and the connecting plate 33, and is locked on the connecting plate by a second nut 61. The third boss 13 of the connecting device body, the first side wall 31 of the cross beam 3, and the connecting plate 33 respectively have holes for the second screws 6 to pass through, which are preferably smooth-walled holes with a diameter equal to or slightly larger than the maximum outer diameter of the inserted portion of the second screws 6, but not limited thereto.
Specifically, during the actual installation, the second boss 12 of the connecting device 1 is first locked by the first screw 5 to the pin 7 passing through the first through hole 41 provided in the side member 4. Since the pin 7 is fixed to the longitudinal beam 4 by means of the first through hole 41 and its profile, the second cam 12 corresponds to a locking connection with the longitudinal beam 4. Then, the installation angle of the connecting device 1 and the cross beam 3 is adjusted, and the first extending portion 111 of the first boss 11 of the connecting device 1 extends into the second through hole 321 on the cross beam 3, so that the first extending portion 111 extends into the inside of the cross beam 3 and is clamped with the inside of the second side wall 32 of the cross beam 3. Finally, the connecting device 1 is rotated, and the third boss 13 of the connecting device 1 and the cross beam 3 are fastened through the threaded connection of the second screw 6 and the built-in second nut 61 of the cross beam 3. The first boss 11 and the third boss 13 cooperate to clamp the connecting device 1 on the cross beam 3, so that the longitudinal beam 4 is connected and fastened with the cross beam 3.
Correspondingly, in the disassembling process, firstly, an inner hexagon wrench is put into the head of the second screw 6, the second screw 6 is loosened, and the second screw 6 is taken out. Then, the connecting device 1 is rotated and the angle of the connecting device 1 is adjusted, and the first extension 111 of the first boss 11 of the connecting device 1 is taken out from the second through hole 321 of the cross member 3. Finally, a socket wrench is placed on the head of the first screw 5, the second screw 6 is unscrewed, the pin 7 is removed from the first through hole 41 in the stringer 4, and the second boss 12 of the connection device 1 is removed from the inside of the stringer 4.
The above is only an exemplary embodiment of the present invention, and in the above embodiment, the first side wall 31 and the second side wall 32 of the cross beam 3 are shown to be adjacent, so that the second end and the third end of the connecting device 1 are located on the same side, and the second boss 12 of the connecting device 1 is located between the first boss 11 and the third boss 13, so that the connection between the third boss 13 and the first side wall 31 of the cross beam 3 is shielded by the connection between the cross beam 3 and the longitudinal beam 4, thereby hiding the second fastener and realizing a simple connecting structure. Meanwhile, in order to realize the above structure and reduce the size of the connecting device 1, the fastening directions of the first fastening member and the second fastening member may not be aligned with the axial direction of the cross member 3 or the side member 4. For example, the first sidewall 31 of the cross beam 3 is opposite to the second sidewall 32, the first sidewall 31 is an upper sidewall of the cross beam 3, and the second sidewall 32 is a lower sidewall of the cross beam 3, so that the second end and the third end of the connecting device 1 are located at two adjacent sides, and the connection between the third boss 13 and the first sidewall 31 of the cross beam 3 is still shielded by the connection between the cross beam 3 and the longitudinal beam 4, thereby hiding the second fastener and realizing a simple connecting structure; for another example, where the size of the connecting device 1 allows, the fastening direction of the first and second fastening members may be aligned with the axial direction of the cross beam 3 or the longitudinal beam 4 to achieve a better fastening connection. Further variants can be implemented by those skilled in the art, which are within the scope of the invention and are not described in detail herein, without departing from the inventive concept.
The embodiment of the invention also provides a table which comprises the connecting structure of the cross beam and the longitudinal beam of the table. When the cross beam and longitudinal beam connecting structure of the table is applied to the table, all the fasteners are hidden in the connecting structure and cannot be exposed, so that the integral attractiveness is improved; the connecting mode between the cross beam, the longitudinal beam and the connecting device is very ingenious, and convenient and fast installation and disassembly can be realized on the basis of ensuring stable connection in normal use. The shape and number of the longitudinal beams, the shape and number of the cross beams and the extending directions of the longitudinal beams and the cross beams in the table of the invention can be adjusted according to actual needs, and are not limited to the contents listed and illustrated in the embodiment.
The cross beam and longitudinal beam connecting structure of the table and the table provided by the invention have the following advantages:
