Abstract
The utility model relates to a jack drive rod assembly which has multifunction practicality. The utility model is characterized in that the front end of a rod body is provided with a sleeve tie-in and the back end of the rod body is provided with a hand grip and an extension section which provides a convex column and a groove. Therefore the rod body can be used as the rotation screws and nuts and the lifting or falling jack safety bolt with all around practical efficacy.
Description
Technical field
The drive spindle structure of the utility model system improvement jack.
Background technology
Known manual jack, rough structure is all as shown in Figure 1: be that a jack 10 has driving head 11, and establish one and have the drive spindle 14 of projection 15 and can plug together in driving head 11, its projection 15 is sticked in driving head 11 draw-in grooves 12, form and back and forth push drive spindle 14 and start driving head 11, and then can rise jack, again, jack 10 is provided with lock 13, keeps the jacking state thereby can lock its oil pressure; Said structure has following shortcoming in fact:
(1) its drive spindle 14 can only not have other function more merely as start driving head 11, in other words, have only special purpose, can not be as the spanner function.
When (2) its desire is rotated lock 13, essential in addition with pliers or other spanner, and obviously use inconvenience.
The utility model content
Major technique, the purpose of the utility model system are: the body of rod be set as front end have telescope joint, the rear end has extension projection and groove, and can be as the function and usage that drives the jack lifting, also can be as the function and usage of spanner switching screw nut.
Specifically, the purpose of this utility model is to provide a kind of jack drive spindle structure, system is set as a lever front end with drive spindle and has telescope joint, body of rod rear end has handle and extension, the extension side face has projection, the groove that the bottom has corresponding jack lock head shapes, can connect sleeve and palm gripping handle by telescope joint, and must be as the spanner function of rotary screw nut, can plug together in jack driving head draw-in groove by extension and projection, and must drive the jack function, but, and must rotate lock by extension groove fit jack lock head.
Description of drawings
Fig. 1 is known three-dimensional exploded view.
Fig. 2 is the utility model block diagram.
Fig. 3 is the utility model running condition figure.
Fig. 4 is the utility model rotation lock scheme drawing.
Fig. 5 is that the utility model extension groove shapes is implemented illustration.
Fig. 6 is another enforcement illustration of the utility model extension groove shapes.
The primary clustering nomenclature:
10 jacks, 14 drive spindles, 22 handles
11 driving heads, 15,24 projections, 23 extensions
12 draw-in grooves, 20 bodies of rod, 25,26,28 grooves
13 locks, 21 telescope joints, 27,29 raised lines
The specific embodiment
Seeing also Fig. 2,3,4, is drive spindle to be set as a body of rod 20 front ends have telescope joint 21, and the body of rod 20 rear ends have handle 22 and extension 23, and extension 23 side faces have the groove 25 that projection 24, bottom have corresponding jack 10 locks 13 head shapes.
The utility model is not when using as jack 10 drive spindles, can be as " spanner " function and usage: as shown in Figure 2, but the sleeve of the required specification of the body of rod 20 front end telescope joints, 21 sockets, handle 22 is held for palm, and can be as the spanner function of rotary screw nut.
When as the driving jack: as shown in Figure 3, the extension 23 of the body of rod 20 can be plugged together in the driving head 11 of jack 10, and make its protruding bolt 24 be sticked in the draw-in groove 12 of driving head 11, form and link one, and be able to the start body of rod 20 knee-actions, but promptly be start driving head 11 and make very heavy jacking moving.
Again, 23 bottoms, the utility model extension are provided with groove 25 (shown in Figure 2), and can be sleeved on jack 10 locks 13 (as shown in Figure 4), form the function of rotatable lock 13.In addition, the groove shapes of 23 bottoms, the utility model extension can be set as having raised line 27,29 in Fig. 5, wholecircle groove 26 shown in Figure 6 and petal-shaped groove 28, the groove, and applicable lock head is the shape of in-line groove.
As shown in the above description, the utility model can make the jack drive spindle except having the function that drives jack, and having more can be as the function and usage of screw nut spanner, rotation lock head, thereby is able to better practicality and promotes effect.
Claims (1)
