Abstract
A butt-insertion foldable connector comprises a locking quick-detaching mechanism and is characterized in that a connector pipe A and a connector pipe B which can be connected by butt joint are respectively provided with shoulders which can lean against each other, the axes of the connector pipe A and the connector pipe B are respectively provided with a waist-shaped slotted hole and a round step through-hole, the two ends of the waist-shaped slotted hole are respectively provided with an annular depression to lock the end of a regulating cap nut, the bolt of the locking quick-detaching mechanism is inserted into the waist-shaped slotted hole and the round step through-hole formed by folding the connector pipe A and the connector pipe B, and then the above components are combined into one body by the regulating cap nut. The locking quick-detaching mechanism is fully utilized, and the bolt of the locking quick-detaching mechanism is used as a hinge shaft to connect and fold the connector pipe A and the connector pipe B. When the connector pipe A and the connector pipe B are folded or connected by butt joint in place, just pulling the handle of the locking quick-detaching mechanism will lock the state of the connector pipe A and the connector pipe B. The utility model is convenient to operate and use, beautiful in appearance and suitable for folding joint of various pipes, in particular suitable for frames of foldable bicycles.
Description
Technical field
The utility model relates to and can roll over the connector construction improvement, especially a kind of mutual-inserting type can be rolled over connector.
Technical background
The effective connector of rolling over is a kind of parts that are used for the pipe fitting butt joint, existing but to be used for pipe fitting doubling connector be hinge hinge structure, it normally is welded on an end of two short tubes respectively on two outer side surfaces of one hinge, rely on hinge two short tubes to amount to the inside, the opening end of two hinges is provided with the quick detach locking element, hinge between two short tubes all can pin the location by the quick detach locking element under opening state or folded position.This loose-leaf hinge structure connector is widely used in the vehicle frame of folding bike, and the vehicle frame that is provided with this connector is collapsible, reaches with this to reduce the bicycle volume, the purpose that is convenient for carrying or preserves.Though above-mentioned hinge hinge structural tube can satisfy the folding needs that connect of pipe fitting with rolling over connector, its folding hinge bit architecture volume is well beyond pipe fitting, and it both had been unfavorable for using, and had also influenced attractive in appearance.
Summary of the invention
The purpose of this utility model is can roll over the deficiency that connector exists at above-mentioned hinge hinge structure, provide a kind of mutual-inserting type can roll over connector, the folding structure of this connector can't conceal the dress except that the quick detach mechanism that is used for its locking position, it is amounted to connection part and is not all exposed, simplify the structure greatly, reduced volume and weight.
The utility model mutual-inserting type can be rolled over connector, comprise: locking quick detach mechanism, it is characterized in that: be equipped with the shoulder that can lean on mutually on adaptor tube A that can dock and the adaptor tube B, be respectively equipped with kidney slot hole and step cutting pattern through hole on the axis of two adaptor tube A, B, the two ends in kidney slot hole are equipped with the circular pit of locking for the adjusting nut end, the screw rod of locking quick detach mechanism is combined into one two joint A, B by adjusting nut after being plugged on kidney slot hole and step cutting pattern through hole after two joint A, B close up.
The design principle that the utility model mutual-inserting type can be rolled over connector is: make full use of locking quick detach mechanism, to lock the screw rod of quick detach mechanism as two adaptor tube A, the connection of B and the hinging shaft of amounting to, because adaptor tube B is provided with the kidney slot hole, when locking quick detach mechanism is opening state, adaptor tube B can make axial slip or radially rotates around screw rod under the qualification of the screw rod of locking quick detach mechanism along the axis of adaptor tube A, as two adaptor tube A, B amounts to and puts in place or dock when putting in place, only need pull the handle of locking quick detach mechanism, can will both simplify Folding structure, and make things convenient for again and manipulated.
The utility model mutual-inserting type can be rolled over connector design science, and structure is ingenious, compact, reasonable, simple, easy for operation, and beautiful shape is a kind of folding connector that connects of all kinds of pipe fittings that more is applicable to, is particularly useful for the vehicle frame of folding bicycle.
The concrete structure that the utility model mutual-inserting type can be rolled over connector is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the structural representation that mutual-inserting type can be rolled over connector.
Embodiment
Can be clear that from Fig. 1 this is that a cylindrical mutual-inserting type can be rolled over connector and is made up of adaptor tube A and B, adaptor tube A, the docking site of B is half round post, two adaptor tube A, after closing up, B is complete cylindrical, form a shoulder 1 between the cylindrical and half round post of adaptor tube A and B, 2, as two adaptor tube A, when the B butt joint puts in place, the end face 3 of adaptor tube A is butted on the shoulder 2 of adaptor tube B, the end face 4 of adaptor tube B is butted on the shoulder 1 of adaptor tube A, two adaptor tube A, offer kidney slot hole 5 and step cutting pattern through hole 6 respectively on the axis of the half-cylindrical section of B, the two ends in kidney slot hole 5 are equipped with the shape ring pit of locking for adjusting nut 78,9; The screw rod 11 of locking quick detach mechanism 10 is set in the kidney slot hole 5 and step cutting pattern through hole 6 of adaptor tube A, B after closing up, and by adjusting nut 7 and cooperating of screw rod 11 adaptor tube A and B being combined into one.The inner of described adjusting nut 7 can embed the shape ring pit 8,9 at 5 two ends, kidney slot hole.
Described locking quick detach mechanism 10 is made up of handle 12, screw rod 11, pad 13, spring 14 and adjusting nut 7.
More solid and reliable for making this mutual-inserting type can roll over the connection of connector, the axis position of shoulder 1,2 roots of two adaptor tube A, B is respectively equipped with pin hand- hole 15,16, two adaptor tube A, B and termination and is respectively equipped with the pin 17,18 that can insert pin hand-hole 15,16.When two adaptor tube A, B butt joint when putting in place, the pin 17,18 that is separately positioned on adaptor tube A, B two ends head just can insert corresponding pin hand- hole 15,16.
The utility model mutual-inserting type can be rolled over the using method of connector: when the handle 12 that will lock quick detach mechanism 10 is pulled to opening state, under the effect of spring 14, eject in the 5 end shapes ring pit 8 from the kidney slot hole adjusting nut 7 the inners, this moment two adaptor tube A, be pine between the B and gallop state, adaptor tube B can move axially with respect to adaptor tube A under the qualification of screw rod 11, at two adaptor tube A, the end pins of B 17,18 all break away from pin hand- hole 15,16 o'clock, two adaptor tube A, B can rotate around screw rod 11, realize the folding of connector, the folding handle 12 of pulling locking quick detach mechanism 10 when putting in place, shape ring pit 9 is held in the adjusting nut 7 inner kidney slot holes 5 that embed in addition, can be with two adaptor tube A, the residing state locking of B.When recovering the straight line connection, the handle of locking quick detach mechanism 10 is pulled 12 to be pulled to opening state, under the effect of spring 14, adjusting nut 7 the inners are held in addition from kidney slot hole 5 in the shape ring pit 9 and are ejected, be pine this moment between two adaptor tube A, the B again and gallop state, then two adaptor tube A, B are pulled directly, and inwardly the end pins of two adaptor tube A, B 17,18 is all inserted and sold hand- hole 15,16, pulling handle 12 again, can be with above-mentioned state locking.
