Description
Technical Field
The utility model relates to a connect the technical field of subassembly spare, more specifically say, it relates to a combination quick connect structure.
Background
In various industries, in order to realize the long length of the rod piece or the quick butt joint of two rod pieces, the two rod pieces are combined and butted through a specific connecting piece. The connecting pieces on the market are inconvenient to butt joint during the use process, and the butt joint stability is not particularly ideal.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a rational in infrastructure simple, the practicality is strong, can realize the combination quick connect structure of quick butt joint.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a combined quick connecting structure, which comprises a cylinder body and a butt joint piece,
the cylinder body is of a hollow structure, a clamping component is arranged in the cylinder body and is movably connected with the cylinder body,
the butt joint piece has one end with outer connecting part and the other end with inner connecting part, the outer wall of the outer connecting part has outer thread, the inner connecting part is inserted into the cylinder and connected to the clamping assembly, the inner connecting part is cone-shaped, the body diameter of the butt joint piece is smaller than the outer connecting part and the inner connecting part,
the joint subassembly comprises a plurality of latch segment combination, and the latch segment combination constitutes has the centre bore that supplies in-connection portion to run through, the last elasticity portion of contradicting with the barrel inner wall that has of latch segment, elasticity portion have elasticity, when the in-connection portion of butt joint piece inserts the centre bore, the latch segment extrudees elasticity portion to the outside to central hole aperture enlarges and supplies in-connection portion to run through the back and arrange the centre bore in to the butt joint piece body.
The utility model discloses further set up to: the locking blocks are three and arranged around the periphery of the central hole and are mutually abutted.
The utility model discloses further set up to: an annular movable groove is formed in the inner wall of the barrel, and the locking block is arranged in the annular movable groove.
Contrast prior art not enough, the beneficial effects of the utility model are that:
through set up the joint subassembly in the barrel, utilize the elasticity answer ability that produces behind its atress to lock the extrusion to the butt joint piece, made things convenient for butt joint piece and composite erection, traditional joint construction relatively, the structure of this application is more convenient when the combination, and the connection stability after the assembly is stronger.

Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 2.
The structure of the present application aims to connect the first connecting structure 11 and the second connecting structure 12 in combination and achieve no purpose of quick butt joint. In order to achieve the aim of the complaint.
The embodiment has the specific structure that: comprises a cylinder body 1 and a butt joint piece,
the barrel 1 is of a hollow structure, an internal thread is arranged on the inner wall of the barrel 1, a plug 4 which is of a hollow structure is arranged at one end of the barrel, the plug 4 is used for connecting a first connecting structure 11 to be connected, a clamping component 3 is arranged at the other end of the barrel 1, and the clamping component 3 is formed by combining three locking blocks 31.
And the butt joint piece has one end serving as an outer connecting part 22 and the other end serving as an inner connecting part 21, the outer wall of the outer connecting part 22 is provided with external threads, and the outer connecting part 22 is used for butting against the second connecting structure 12 to be installed.
The inner connecting part 21 of the cylinder 1 is inserted into the cylinder 1 and connected with the clamping assembly 3, the inner connecting part 21 is in a conical shape, and the diameter of the body 20 of the butt joint piece is smaller than that of the outer connecting part 22 and the inner connecting part 21.
The three locking blocks 31 are three-piece members of a ring, and when the three locking blocks 31 are connected together, the ring is formed, so that a central hole 30 is formed by combining the inner walls of the three locking blocks. The three locking blocks 31 are disposed around the outer circumference of the central hole 30 and interfere with each other.
The welding has elastic part 32 on the outer wall of latch segment 31, and elastic part 32 is one and has elastic shell fragment, extrudees the inner wall of shell fragment bending and barrel 1, for the installation to latch segment 31, sets up annular movable groove 10 on the inner wall that barrel 1 corresponds the position, for the installation of latch segment 31, sets up the bore of annular movable groove 10 and is greater than the height of latch segment 31, can satisfy the state after the latch segment 31 atress extrudees moreover.
In the process of connecting the butt joint piece and the barrel 1, when the inner connecting part 21 of the butt joint piece is inserted into the central hole, the locking block 31 extrudes the elastic part 32 outwards, so that the aperture of the central hole 30 is enlarged, and as the inner connecting part 21 is in a conical shape, the central hole is gradually enlarged when being stressed and extruded, so that the pressure which can be borne by the elastic part 32 is uniform, and the rigidity fatigue of the elastic part is reduced. Since the diameter of the body 20 is smaller than the brightness of the body, after the inner connecting portion 21 penetrates the central hole, the central hole is contracted due to the elastic recovery of the elastic portion 32 after the central hole is free from external force, so that the body 20 just fills the central hole, and the installation of the butt joint member is completed.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
