Above-mentioned two kinds of connection modes are to the weldquality between adapter sleeve and main chord, and the weldquality between otic placode and main chord has higher requirement.Therefore there is following shortcoming: 1) weld seam of standard knot junction is critical welding seams, need detect a flaw, welding process more complicated.2) because welding deformation, cannot ensure completely dimension limit.3) there is not guide function between attaching parts, install and compare effort.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of standard knot tenon and main chord connection structure, and in standard knot junction without the need to welded connections, manufacturing process is simple, and tenon has guide function, easy for installation, connects reliable.
To achieve these goals, a kind of standard knot tenon that the utility model adopts and main chord connection structure, comprise the first standard knot, first standard knot contains main chord, also comprises second standard knot that can be connected up and down with the first standard knot and two ends and all can insert connection tenon in main chord of standard section;
The two ends up and down of described connection tenon are respectively equipped with one group of pin shaft hole, often organize pin shaft hole and comprise two spatially vertical bearing pin through holes, be equipped with respectively in the bearing pin through hole that two of described connection tenon lower end are spatially vertical for being fixed on the first bearing pin on described first main chord of standard section and the second bearing pin by connecting tenon, first, second bearing pin described is fixed locked on the first main chord of standard section;
The upper end of described connection tenon adopts on the main chord in detachable insertion second standard knot, connects the spatially vertical bearing pin through hole of two of tenon upper end built with the bearing pin being fastenedly connected tenon and the second standard knot.
As improvement, the bearing pin shape of through holes at the described upper and lower two ends of connection tenon is identical, and it is regularly arranged on connection tenon often to organize bearing pin through hole.
As improvement, the spacing of adjacent two bearing pin through holes is identical respectively.
As improvement, described bearing pin through hole runs through the axle center connecting tenon respectively.
As improvement, on described connection tenon, the spacing of adjacent two bearing pin through holes is certain.
The beneficial effects of the utility model are: by adopting the connection tenon that can insert main chord of standard section, when standard knot is installed, junction is without the need to welded connections, and manufacturing process is simple; In addition, the connection dimension of tenon and main chord is ensured by machinework, easier for installation, connects more reliable; The connection tenon adopted has guide function, installs more convenient, improves the installation effectiveness of standard knot, effectively meet customer need.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by accompanying drawing and embodiment, the utility model is further elaborated.But should be appreciated that, specific embodiment described herein, only in order to explain the utility model, is not limited to scope of the present utility model.
As shown in Figure 5 and Figure 6, a kind of standard knot tenon and main chord connection structure, comprise the first standard knot 2, first standard knot 2 containing main chord, also comprise second standard knot 3 that can be connected with the first standard knot about 2 and two ends and all can insert connection tenon 1 in main chord of standard section;
The two ends up and down of described connection tenon 1 are respectively equipped with one group of pin shaft hole, often organize pin shaft hole and comprise two spatially vertical bearing pin through holes, be equipped with respectively in the bearing pin through hole that two of described connection tenon 1 lower end are spatially vertical for being fixed on the first bearing pin 4 and the second bearing pin 5 on described first standard knot 2 main chord by connecting tenon 1, first, second bearing pin described is fixed locked on the first standard knot 2 main chord;
The upper end of described connection tenon 1 adopts on the main chord in detachable insertion second standard knot 3, connects the spatially vertical bearing pin through hole of two of tenon 1 upper end built with the bearing pin being fastenedly connected tenon 1 and the second standard knot 3.
As the improvement of embodiment, the bearing pin shape of through holes at described connection tenon about 1 two ends is identical, and it is regularly arranged on connection tenon 1 often to organize bearing pin through hole.Adopt the bearing pin through hole of same size, be convenient to the processing connecting tenon 1, adopt bearing pin through hole regularly arranged on connection tenon 1 simultaneously, ensure that the stability that tenon is connected with main chord.
As the improvement of embodiment, the spacing of adjacent two bearing pin through holes is identical respectively, while guarantee is easy to process, the bearing pin through hole of same intervals is relied on to make upper and lower standard knot and be connected tenon 1 stable connection, guarantee to connect uniform force on tenon 1, avoiding local pressure, excessive to cause upper and lower standard knot to connect unstable simultaneously.
As the improvement of embodiment, described bearing pin through hole runs through the axle center connecting tenon 1 respectively, guarantees that bearing pin is each passed through the center connecting tenon 1, and connection tenon 1 is connected firmly with main chord on standard knot, ensures to connect the overall uniform force of tenon 1 simultaneously.
Improve as embodiment, on described connection tenon 1, the spacing of adjacent two bearing pin through holes is certain, easy to process, stabilized structure.
During use, connect tenon 1 two ends and insert the two joint standard knots connected up and down respectively, as in the main chord of the first standard knot 2 and the second standard knot 3, by the bearing pin of square crossing in solid, as the first bearing pin 4 makes connection tenon 1 be connected with main chord with the second bearing pin 5 respectively; Fixed by bearing pin locked after connection tenon 1 is fixing by bearing pin with main chord upper end in standard knot manufacturing process, in use procedure, tenon generally cannot be dismantled, and therefore integral structure is very firm.This structure can make the tolerance on fit between connection bearing pin and connecting bore more reasonable, improves reliability of service and the safety of standard knot.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection domain of the present utility model.
