The invention aims to overcome the defects of the prior art and provide a burner nozzle connecting structure, namely, the inner core and the outer diameter are connected in a threadless way, so that when a product is stressed, the shearing force applied to the product is minimum, and the extrusion force and the interlayer bonding force are maximum, so that the breaking tension of the product is increased by two times on the basis of the prior connecting technology.
The purpose of the invention is solved by the following technical scheme:
the burner nozzle connecting structure comprises a cylindrical connecting rod, wherein a cylindrical connector is inserted into the end head of the cylindrical connecting rod, one end of the connector is an inserting end, the other end of the connector is a metal connecting end, a convex skirt is arranged in the middle of the connector, a locking cap is sleeved on the outer wall side of the end head of the cylindrical connecting rod, a connector through hole is formed in the top of the locking cap, an annular buckling groove is formed in the circumferential direction of the outer wall side of the end head of the cylindrical connecting rod, and an annular buckling groove is also formed in the circumferential direction of; the cylindrical connecting rod and the lock cap are connected in a matched mode in which the annular buckling grooves are buckled with each other.
The wall surface of the insertion end of the connector is provided with a reticulate pattern, and the head part of the insertion end is processed into a circular angle shape.
The side wall of the metal connecting end of the connector is a smooth cylindrical surface, and a chamfer is machined at the head of the metal connecting end.
The metal connecting end is provided with a radial connecting hole or an axial through groove.
In the invention, the inner core of the composite tubular product adopts the reticulate pattern without screw threads, and the outer diameter adopts the arc groove type combined connection structure (namely an annular buckle groove structure), so that when the product is stressed, the shearing force borne by the product is minimum, the extrusion force and the interlayer bonding force are maximum, the damage tension of the product is maximum, and the damage tension is equivalent to the strength of the composite tubular product; and the single common thread can ensure that the shearing force borne by the composite product is the largest when the composite tubular product is stressed, so that the breaking tension is the smallest, and the breaking tension is one third of the strength of the composite tubular product.

Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
referring to fig. 1 and 2, the burner connecting structure comprises a cylindrical connecting rod 1, wherein a cylindrical connector 3 is inserted into the end of the cylindrical connecting rod 1, one end of the connector 3 is an inserting end 7, the other end of the connector is a metal connecting end 8, a convex skirt 6 (shown in fig. 5) is arranged in the middle of the connector 3, a locking cap 2 is sleeved on the outer wall of the end of the cylindrical connecting rod 1, and a connector through hole 4 is formed in the top of the locking cap 2. The side surface of the outer wall of the end head of the cylindrical connecting rod 1 is circumferentially provided with an annular catching groove 5, and the inner side wall of the corresponding lock cap 2 is also circumferentially provided with the annular catching groove 5; thus, the cylindrical connecting rod 1 and the locking cap 2 are matched and connected in a buckling mode through the annular buckling groove 5.
According to the above description of the structure of the present invention, the connection structure is a cross-hatched screw-free connection structure, the outer diameter is a circular ring groove 5 combination connection structure, the wall surface of the insertion end of the connector 3 is processed with cross-hatched patterns to increase friction force for matching connection with the inner wall of the cylindrical connection rod 1, and the head of the insertion end 7 is processed into a circular angle shape, so that the cylindrical connection rod 1 can be easily inserted when being installed.
The metal connecting end 8 of the connecting head 3 can be designed into various shapes according to the requirements of the connecting object, for example, the side wall of the metal connecting end 8 in fig. 1 is a smooth cylindrical surface, and the head of the metal connecting end is processed into a chamfer so as to be convenient to assemble and disassemble. Radial connecting holes 9 or axial through grooves 10 can be machined on the metal connecting end 8 according to requirements, and the structure is shown in fig. 3 and 4.
When the connector is assembled, the inserting end 7 of the connector 3 is inserted into the cylindrical connecting rod 1 until the convex skirt 6 of the connector 3 is clamped at the end of the cylindrical connecting rod 1, then the locking cap 2 penetrates through the metal connecting end 8 of the connector through hole 4 and is fastened to the cylindrical connecting rod 1 through the annular fastening groove 5 in a matched and fastened mode, at the moment, the locking cap 2 can lock the convex skirt 6, and therefore the connector 3 is fastened, and the connecting rod 1 and the connector 3 are fastened into a whole.
The invention is suitable for connecting a composite tubular product and metal, and the connecting structure without screw thread combination inside and outside the connecting structure is mainly used for the composite tubular product and aims to improve the breaking tension to the maximum extent.
