Abstract

The utility model relates to a connector which is composed of a screw rod, a screw nut sheathed on the screw rod, and a sleeve barrel, wherein, the sleeve barrel is provided with a pin hole and a socket sleeve, and the socket sleeve is provided with a pin hole. One end of an opening bolt is provided with a handle, a pin shaft is arranged in the opening of the other end, and the pin shaft is sheathed with a pin bolt. One end of the screw rod is fixed on a master part such as a power-assisted bicycle, the socket sleeve is fixed on an accessory such as a side car, and the sleeve barrel and the socket sleeve are sheathed together, so that the two pin holes are coincident. The opening bolt is inserted into the pin holes, and the master part and the accessory are tightly connected together. The master part and the accessory can be disassembled as long as the opening bolt is extracted to achieve the purposes of quick assembly, quick disassembly, and firm and reliable connection.

Description

Adaptor union

The utility model is a mechanical fastener, particularly be the adaptor union of two-wheel car and sidecar fast assembling-disassembling.

The attaching parts of bicycle and sidecar has many kinds now, the domestic attaching parts that a kind of coupling type is arranged, and dismounting is very convenient, but unstable, dangerous; The attaching parts that a kind of U-shaped bracket is abroad arranged, U-shaped bracket two ends are separately fixed on the screw at bicycle rear axle two ends, cramp bar one terminates on the screw of bicycle saddle bottom, one end is connected on the U-shaped bracket, this connection is fastening, but is connected on the bicycle rear axle unreasonablely, and tension, performance antitorque, bending resistance are bad, the U-shaped bracket is yielding, and bicycle rear axle is also had adverse effect; Chinese patent literature has the people that the U-shaped bracket has been done improvement, and the U-shaped bracket makes tubulose, and the middle part adds a reinforced rib, and one side and chain stays are fastenedly connected, and unfailing performance has been strengthened like this, but dismounting is more time-consuming, bothersome.

The purpose of this utility model provides a kind of simple in structure, safe and reliable, the adaptor union that two articles that again can fast assembling-disassembling links to each other.

The purpose of this utility model is achieved in that accompanying drawings is as follows:

A kind of adaptor union, its constructional feature is:

1. an end waits to be fixed on the screw rod 1 on 12 of the main parts, sleeve 3 of cover on its other end outside thread, and sleeve 3 other ends are provided with the penetrating pin-and-hole 4 of barrel up and down;

2. an end waits to be fixed on the cover for seat 10 on 13 of the associate members, and cover for seat 10 other ends barrel up and down are provided with penetrating pin-and-hole 11, and pin-and-hole 4 can be nested in pin-and-hole 11, and the aperture unanimity;

3. opening latch 6 one ends are provided with handgrip 7, are provided with bearing pin 8 in the two ends of other end opening, are with rotating movable lug 9 on the bearing pin 8.

Accompanying drawing 1 is the adaptor union cross-sectional view.

Description of drawings and embodiment:

1 be screw rod, 2 for nut, 3 for sleeve, 4 for pin-and-hole, 5 for cover for seat, 6 for the opening latch, 7 for pin, 8 for bearing pin, 9 for the pin tongue, 10 for bolt, 11 for pin-and-hole, 12 for main part, 13 for annex.

Can be found out that by accompanying drawing screw rod 1 one ends are used for fixing on main part 12, screw rod 1 is a lot of with the fixing means of main part 12, for example make internal thread in screw rod 1 termination, Pass in the internal thread that main part 12 screws in screw rods 1 with bolt 10, tighten can One end of screw rod 1 firmly is fixed on the main part; Also can be directly an end of screw rod 1 Be welded on the main part; The other end of screw rod 1 has external screw thread, and nut 2 and sleeve 3 are twisted Outside at screw rod 1; One end of cover for seat 5 is fixed on the annex 13, fixing means Also have with top the same various ways; Have pin-and-hole 11 on the other end of cover for seat 5, Pin-and-hole 4 should be consistent with the aperture of pin-and-hole 11, and sleeve 3 should be able to overlap with cover for seat 5 Be connected together, and pin-and-hole 4 is overlapped with pin-and-hole 11.

Opening latch 6 one ends in the accompanying drawing are provided with handgrip 7, two walls of other end opening Between be provided with a bearing pin 8, cover has a pin tongue 9 on the bearing pin 8, and makes pin when making The center of gravity of tongue 9 is not on bearing pin 8.

In screw rod 1 outside of sleeve 3 fronts, add nut of cover 2 and do in the accompanying drawing 1 The keeper of sleeve 3.

Practicality is exemplified below: with the power-assisted vehicle frame is main part 12, is annex 13 with the sidecar vehicle frame.At first screw rod 1 usefulness bolt 10 is fixed on the power-assisted vehicle frame 12, again nut 2 is enclosed within screw rod 1 outside, again sleeve 3 is enclosed within screw rod 1 outside, and tighten surely the firmly position of sleeve 3 on screw rod 1 with nut 2 after choosing the position, cover for seat 5 is welded on the sidecar vehicle frame 13, then cover for seat 5 one end sleeves on sleeve 3, pin-and-hole 4 is alignd with pin-and-hole 11 coincidences, hand-held pin sets right the pin tongue 9 on the opening latch 67 consistent with opening latch 6 directions and inserts pin-and-hole 4 and 11 overlap in the hole, because the center of gravity of pin tongue 9 is not on bearing pin 8, the direction of 9 automatic break-ins of meeting of pin tongue and opening latch 6 is angled, also just just in time having played pinning opening latch 6 can not throw off, finished boosted vehicle and sidecar is fixedly connected as process, take apart if want, extract pin-and-hole out as long as set upright pin tongue 9, just finished the task of taking apart of two cars immediately, finish the bonded assembly task otherwise insert pin tongue 9.

The utility model attaching parts not only is fit to boosted vehicle, two-wheel car is connected with sidecar, and the connection of any two parts all can use, and is particularly useful for the fast assembling-disassembling task.

Advantage of the present utility model is a lot, and is simple in structure, safe and reliable, especially suitable Object in fast assembling-disassembling connects, and this is its maximum advantage, and cost is low, easy-maintaining, It also is its advantage.
