But, running into while connecting than thick parts or multi-layer part, above-mentioned screw be not long be exactly curtailment, affect join strength and affect attractive in appearancely, can not meet the connection needs.Therefore, if screw designs can be become to the split type structure that can combine, just can not be subject to the restriction of connecting length fully, the energy flexible Application is in various occasions.
Summary of the invention
the problem that 1, will solve
For the above-mentioned problems in the prior art, the invention provides a kind of ten thousand joint screws, its be a kind of can be according to the needs of connecting length, and the knockdown screw that can freely convert, no matter be long parts or connecting a plurality of parts can apply at any time, reasonable in design.
2, technological scheme
In order to address the above problem, the technical solution adopted in the present invention is as follows:
A kind of ten thousand joint screws, comprise screw cap, also comprises split type screw rod, and described split type screw rod comprises head rod and minute bar, and an end of an end of described head rod and minute bar cooperatively interacts and links together.
Further, be provided with successively the first joint, screw thread and the first connection chamber on described minute bar, described the first joint is fixed in a screwed end of minute bar, and described the first connection chamber is positioned at minute polished rod of the bar the other end; Described the first joint comprises latch and axis body, and described latch and axis body are one-body molded; Described latch has 3, is segment structure, the three centered by axis body around an end that is arranged in axis body; Described head rod from bottom to top is provided with screw head, screw thread and the second connection chamber successively, and described screw head is positioned at the screwed end of head rod, and described connection chamber is positioned at the polished rod of the head rod the other end.
Further, described the second connection chamber comprises the guiding groove axially arranged along head rod and the locating slot radially arranged along head rod, and described locating slot is positioned at the bottom of the sidewall of guiding groove; The shape of the cross section of described locating slot and guiding groove all matches with the shape of latch; Be connected with the second joint on the end face of one end of described screw cap, described the second joint is identical with the first joint; Within described minute, bar has N, and described N is more than or equal to 1.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
Screw rod of the present invention comprises head rod and minute bar, and both combine by the joint and the connection chamber that cooperatively interact, can select according to the length of required connected element minute bar of respective numbers; In addition, screw cap of the present invention is detachable after connection completes, and can not stay projection in the connecting surface of parts, does not affect the appearance, easy to use, reasonable in design.
