Abstract
The utility model relates to a jack connector structure, which enables a connector of a jack to be higher in practicality. The jack connector structure is mainly characterized in that the connector is combined to a screw joint of the jack and is provided with a sleeving head and pivoting pieces, the sleeving head is provided with a sleeving hole, and a sectioning groove is formed between the two pivoting pieces. By means of the structure, the pivoting pieces can be combined to the screw joint with two pivoting pieces and a combined groove and can be combined to the screw joint with a single pivoting piece, and the sleeving head of the connector can be used for combination of a plugging head and a socket head of a wrenching bar, therefore, the jack connector structure is applicable to combined connection of various forms, and is high in practicality.
Description
Technical field
The utility model relates to a kind of jack connector structure, and it makes the connector that is combined in the jack screw joint, applicable to the winding of plurality of specifications, reaches extensive practical effect.
Background technology
The jack of screw rod lifting mode like Fig. 1, jack 10 shown in Figure 3, has a joint in screw front end and supplies to link screw rod, wrenching bar.And existing jack joint design all is to be set as fixed single structure kenel, specifically; Joint is set as the block sleeve that supplies the socket wrenching bar of polygon, or is set as and has square opening and supply the insert group wrenching bar, in other words; The block inapplicable grafting wrenching bar of polygon; Therefore square poroid inapplicable sleeve has the limited of instrument specification, causes with inconvenient.
The utility model content
The utility model promptly provides a kind of practicality jack connector widely; Major technique, purpose are: the pin-jointing piece of connector is set as has profile groove; Thereby can supply to be connected to jack screw and have the joint of two pin-jointing pieces, also can supply to be connected to the joint of monolithic pin-jointing piece; Again, the bell and spigot joint of connector is provided with sleeve joint hole, but but and sacrificial vessel has the wrenching bar fit of collet head, also sacrificial vessel has the wrenching bar of connection-peg to peg graft.Therefore, can obtain being suitable for the extensive practical effect of plurality of specifications through the utility model.
In other words; The utility model proposes a kind of jack connector structure, be one to be combined in the connector of jack screw joint, its structure be set as have bell and spigot joint, pin-jointing piece; Bell and spigot joint is set as has sleeve joint hole; Bell and spigot joint can supply collet head fit, the sleeve joint hole of handlebar stem then can supply the connection-peg of wrenching bar to plug together, and the pin-jointing piece of connector is set as two and have axis hole, forms between two pin-jointing pieces to have profile groove; Two pin-jointing pieces are capable of being combined in the screw rod joint that also has two pin-jointing pieces, but profile groove then sacrificial vessel the screw rod splice combinations of monolithic pin-jointing piece is arranged.
Description of drawings
Fig. 1 is the structural perspective of the utility model;
Fig. 2 is the combination stereogram of Fig. 1;
Fig. 3 is that the utility model is used in the usage example figure that joint is the monolithic pin-jointing piece;
Fig. 4 is the combination stereogram of Fig. 3.
[main element nomenclature]
10 jacks, 21 bell and spigot joints
11 screw rods, 22 sleeve joint holes
12,16 joints, 24 profile grooves
13,17,23 pin-jointing pieces, 25 axis holes
14 combination slots, 30 handlebar stems
15 bolt 31 connection-pegs
20 connectors, 32 collet heads.
The specific embodiment
See also Fig. 1, Fig. 2; Be one to be combined in the connector 20 of jack 10 screw rods 11 joints 12; Its structure be set as have bell and spigot joint 21, pin-jointing piece 23, bell and spigot joint 21 is set as has sleeve joint hole 22, pin-jointing piece 23 is set as two and form and to have profile groove 24 and to have axis hole 25.
Through above-mentioned link head 20 structures; Can obtain following effect, advantage: (1) is like Fig. 1, shown in Figure 2; When jack 10 screw rods 11 joints 12 are biplate pin-jointing piece 13 shapes; Two pin-jointing pieces 23 of connector 20 can insert in two pin-jointing pieces 23 combination slots 14 of screw rod 11 joints 12, and fitted shaft bolt 15 is combined integrated; (2) when screw rod 11 joints 16 of jack 10 are monolithic pin-jointing piece 17, like Fig. 3, shown in Figure 4, the profile groove 24 that two pin-jointing pieces of connector 20 are 23 can supply the pin-jointing piece 17 of screw rod 11 joints 16 to insert, and also fitted shaft bolt 15 is combined integrated; (3) connector 20 bell and spigot joints 21 have sleeve joint hole 22, therefore can be as shown in Figure 2, and supply connection-peg 31 sleeve joint holes 22 of wrenching bar 30 to link rotary screw 11; (4) bell and spigot joint 21 of connector 20 then can be as shown in Figure 4, and sacrificial vessel has handlebar stem 30 fits of collet head 32 to link rotary screw 11.
Can know that by above-mentioned explanation the utility model is applicable to jack screw joint, the handlebar stem head of different size, and reach extensive practical effect.
