The retractable connector comprises a column-shaped inner core (1), a hole-shaped inner core (2), an upper pipe wall (3) and a lower pipe wall (4), wherein a straight-line cylinder is arranged on the base of the column-shaped inner core (1), a straight-line round hole is formed on the base of the hole-shaped inner core (2), the round hole is matched with the cylinder, the column-shaped inner core (1) and the hole-shaped inner core (2) form a structure with an upper part and a lower part which are oppositely inserted through the matching of the round hole and the cylinder, a saw-toothed seam structure is arranged on the butting surface of the upper pipe wall (3) and the lower pipe wall (4), the upper pipe wall (3) and the lower pipe wall (4) can be butted to form an integral structure, the column-shaped inner core (1) is fixed in the upper pipe wall (3), and the hole-shaped inner core (2) is fixed in the lower pipe wall (4). The retractable connector has the characteristics of simple structure and low manufacturing cost, and is convenient to install.
Description
(1) technical field
The utility model relates to a kind of scalable connecting head, is used for the connection between two pipelines, can be used for the connection of all kinds pipeline.
(2) background technique
At present, the connection of the pipeline modes of directly welding that adopt connect more, yet adopt this type of Placement, when the pipeline expanded by heating, meet cold contraction or because of the external force effect descends when rising, pipeline will produce deformation even damage.For solving above-mentioned situation, Chinese patent 200620008660.5 has been announced the differential coupling arrangement of a kind of mine cage guide, and " differential connection " mode of utilization makes the stationarity cage guide form the cage guide that can contract, yet this type of mode has the following disadvantages:
(1) when complex structure, installation fee: need the extra structures such as special cage guide, cage guide slippage joining plate, guide fixed block of installing, not only cause complex structure, and make and to expend a large amount of time when installing.
(2) work efficiency is low: " differential connection " mode adopts cross structure to inserting, and forms pin and box sub, but is adding man-hour, need expend than multiple operation for cross key and cross recessed processing, and process time is longer, has influenced manufacturing efficiency, and waste material.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, easy for installation and scalable connecting head that cost of production is low is provided.
The purpose of this utility model is achieved in that a kind of scalable connecting head, include the cylindricality inner core, the hole shape inner core, upper tube wall, following tube wall, described cylindricality inner core pedestal is provided with a straight line cylinder, described hole shape inner core has a straight line circular hole that matches with linear cylindrical on pedestal, cylinder and circular hole are slidingly matched, form mutual-inserting type structure up and down, described upper tube wall and following tube wall interface place are provided with the zigzag fashion seam construction, and upper tube wall and following tube wall can dock and form a complete structure, described cylindricality inner core is fixed in the upper tube wall, and described hole shape inner core is fixed in the following tube wall.
The scalable connecting head of the utility model, upper tube wall and following tube wall are that two-part were made about a segment pipe was divided into by the line cutting.
Working principle of the present utility model is:
During use, two segment pipes with the needs butt joint, one section is welded mutually with upper tube wall, another section is connected with following tube wall, be complementary by circular hole and cylinder subsequently and under the leading role of upper tube wall and following tube wall seam construction, be connected, seam construction leaves certain surplus and does not combine closely during butt joint, when the pipeline expanded by heating, meet cold contraction or when descend rising because of the external force effect, because the cylindricality inner core adopts circular hole to be connected with the coupling of cylinder with the hole shape inner core, upper tube wall adopts the zigzag fashion seam construction to be connected with following tube wall, be active connection, thereby can easily realize flexible effect, effectively prevent to cause the bend by pressure of pipeline because of expanding with heat and contract with cold, distortion, break, or seam extension expansion, safe operation influenced.
The beneficial effects of the utility model are:
(1) simple in structure, easy for installation: as to compare with original technology, dwindled size greatly, simplify the structure, during installation, only two segment pipes need be welded mutually with upper tube wall of the present utility model and following tube wall respectively and get final product, reduced the installation time greatly.
(2) cost of production is low: cylindricality inner core of the present utility model and hole shape inner core,, easy to process than the cross of original technology to inserting type " differential connection " mode, only need simple boring and cutting to get final product machine shaping, greatly reduce into the product time, saved cost of production and human cost.
(3) economize in raw materials: the utility model upper tube wall and following tube wall are that two-part were made about a segment pipe was divided into by the line cutting, and be not only easy to process, and the waste that can not produce raw material, saved raw material.
