RELATE APPLICATIONS

This application claims benefit to Chinese Patent Application 201620181339.0, filed on Mar. 10, 2016, the specification of which is incorporated herein by this reference.


FIELD OF THE INVENTION

The present invention relates to a mechanism for connecting two beams.


DESCRIPTION OF THE PRIOR ART

In the prior art, most tents have a one-button quick-disassembly mechanism by which a tent can be quickly assembled or disassembled. However, such a quick-disassembly mechanism is used usually in small tents, and seldom in large tents due to limited strength of the quick-disassembly structure. In large tents, the connection between columns and beams is generally realized by connecting ends to sleeves. Such a connection way is labor-consuming in assembling since one connection joint is to be screwed with at least three support rods, and is thus unable to realize quick assembly and disassembly of large tents. In addition, due to the lack of an appropriate splicing mechanism, common tubes or rods are generally used as beams. Such a structure is at a disadvantage for splicing and storage.


SUMMARY OF THE INVENTION

A technical problem to be solved by the present invention is, in view of the prior art, to provide a mechanism for connecting two beams. This mechanism can realize quick assembly and disassembly of beams, and facilitate the storage and transportation thereof.


To solve this technical problem, the mechanism for connecting two beams comprises a left beam formed by an upper cross bar with a first end, a lower cross bar with a second end, and a vertical plate connected to the first end of the upper cross bar and to the second end of the lower cross bar, the vertical plate having a width greater than a width of the upper cross bar and a width of the lower cross bar, the vertical plate having two edges protruding laterally away from the upper cross bar and the lower cross bar; and a right beam formed by an upper cross bar with a third end, a lower cross bar with a fourth end, and a vertical socket for receiving the vertical plate, the vertical socket being connected to the third end of the upper cross bar and to the fourth end of the lower cross bar, the vertical socket having two opposing curled lateral edges protruding laterally away from the upper cross bar and the lower cross bar, wherein, the two protruding edges of the vertical plate are inserted between the two opposite curled edges of the vertical socket.


Preferably, the vertical plate and the vertical socket are respectively connected to the corresponding upper cross bar and lower cross bar by bolts.


Preferably, a first mounting hole formed on the upper cross bar of the left beam and a second mounting hole formed on the upper cross bard of the right beam.


Preferably, a block protruding outside is provided at the bottom of the vertical socket for stopping the vertical plate.


Compared with the prior art, in the present invention, the mechanism for connecting two beams of the present invention can realize quick assembly and disassembly; and meanwhile, under this mechanism, a beam is very firm after being connected, and thus applicable to large tents.





BRIEF DESCRIPTION OF THE DRAWINGS


FIG. 1 is a perspective view of a mechanism for connecting two beams according to the embodiment of the present invention used in a supporting frame of an iron tent;



FIG. 2 is an exploded view of the Part-A of FIG. 1;



FIG. 3 is a perspective view of the Part-A of FIG. 1 showing a top tube mounted on the beam; and



FIG. 4 is another exploded view of the left beam and the right beam of the mechanism for connecting two beams according to the embodiment of the present invention.





DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

To enable a further understanding of the present invention content of the invention herein, refer to the detailed description of the invention and the accompanying drawings below:


As shown in FIG. 1, a mechanism for connecting two beams used in a tent, comprises four columns 1 and four beams 2; each beam 2 is disposed across at the top of the two adjacent columns 1; the four beams 2 are arranged in a rectangle, and each beam 2 comprises a left beam 21 and a right beam 22.


The mechanism for connecting of the left beam 21 and the right beam 22 is shown in FIG. 2. The left beam 21 formed by an upper cross bar with a first end, a lower cross bar with a second end, and a vertical plate 23 connected to the first end of the upper cross bar and to the second end of the lower cross bar, the vertical plate 23 having a width greater than a width of the upper cross bar and a width of the lower cross bar, the vertical plate 23 having two edges protruding laterally away from the upper cross bar and the lower cross bar; and a right beam 22 formed by an upper cross bar with a third end, a lower cross bar with a fourth end, and a vertical socket 24 for receiving the vertical plate 23, the vertical socket 24 being connected to the third end of the upper cross bar and to the fourth end of the lower cross bar, the vertical socket 24 having two opposing curled lateral edges 25 protruding laterally away from the upper cross bar and the lower cross bar, wherein, the two protruding edges 28 of the vertical plate 23 are inserted between the two opposite curled edges 25 of the vertical socket 24. Bolt holes 27 are formed on the vertical plate 23 and the vertical socket 24, and the vertical plate and the vertical socket 24 are fixedly connected to a corresponding beam by bolts into the bolt holes 27.


And a block 24a protruding outside is provided at the bottom of the vertical socket 24 for stopping the vertical plate 23, in order to prevent the vertical plate 23 from falling down from the vertical socket 24.


With regard to the beam of the invention, the splicing can be realized by inserting the pin of the left beam inserted into the pin socket of the right beam from the top down; and when in disassembly, this operation is performed reversely.


A mounting hole 29 for a top tube is formed on the upper cross bar of the left beam or the right beam. The mounting hole 29 for a top tube is configured to mount a top tube mechanism. As shown in FIG. 3, the top tube mechanism includes a top tube 31 and a securing sheet 32; bolt holes corresponding to the mounting hole 29 for a top tube are formed on two sides of the securing sheet 32; and the top tube mechanism is fixed onto the beam after bolts into the bolt holes.


It will be understood by those skilled in the art that various modifications, changes and combinations can be made to the implementations as described above without departing from the protect scope of the present invention, and those modifications, changes and combinations shall be regarded as falling into the scope of the inventive concept.
