Abstract

The utility model discloses a ratchet-type jack, which comprises a pedestal, a connection rod mechanism arranged on the pedestal, an ejector arranged on the upper end of the connection rod, a screw pivoted with the connection rod mechanism, and a connection head arranged on the end of the screw for assisting in rotating a tool, wherein, a the connection head on the end of the screw has a polyhedral end matched with a ratchet tool. Since the polyhedral end is sleeved in the ratchet tool, the ratchet tool can rotate in the reverse direction when rotating to any angle to adjust the sheathing position with the polyhedral end when ejecting the jack, while not rotating the ratchet tool by a user to an angle where force is difficultly exerted and repeatedly inserting/drawing the ratchet tool, thereby preventing contact between the end of the ratchet tool and the ground, and greatly improving the jack ejection efficiency. The ratchet-type jack has the advantages of simple structure, convenient manufacture, smooth operation, and reduced consumption of effort for ejecting the jack.

Description

The ratchet-type jack

Technical field

The utility model relates to a kind of jack, particularly a kind of jack of rising that rotates by ratchet tool.

Background technology

Tradition is risen the jack that automobile is used as shown in Figure 1, mainly comprise base 1, acrosome 3, connecting rod mechanism 2 and be connected the screw rod 4 at connecting rod mechanism two ends, be provided with one in the screw rod end and be rotationally connected 5, connector is provided with through hole, the user will articulate through hole on the connector, a front end axle 71 that holds rotating lever 7 afterwards with rotating lever 7 turning tools such as grade when rising jack, another holds swing handle 72 rotations and drives screw rod 4 rotations, realizes rising of jack; When rising than the weight body, need bigger strength, be unfavorable for user's operation that strength is less, and when just beginning to rise jack, instrument turns to the bottom position ground of conflicting easily, instrument need be extracted through hole, insert through hole from another face again and be rotated, make complex operation.

Summary of the invention

At above-mentioned deficiency, it is a kind of when rising that the purpose of this utility model is to provide, and do not need the user to plug the jack of turning tool repeatedly.

The technical scheme that its technical matters that solves the utility model adopts is:

The ratchet-type jack, comprise base, be installed in connecting rod mechanism on the base, be installed in the pipe link upper end acrosome, be articulated in the screw rod on the connecting rod mechanism and be arranged on the connector that the screw rod end cooperates turning tool, it is characterized in that: the connector of described screw rod end is provided with the polyhedron end that cooperates with ratchet tool.

The beneficial effects of the utility model are: because the screw rod end is provided with the polyhedron end that cooperates with ratchet tool, the user is socketed in the polyhedron end by ratchet tool and rotates and rise jack, feasible rotation is more laborsaving, and ratchet tool turns to any angle and can backwards rotation adjusts socket position with the polyhedron end, be not difficult to angle firmly and do not need the user that ratchet tool is turned to, more do not need to plug repeatedly ratchet tool and contact with ground, improved greatly and rotated the efficient of rising jack to avoid the ratchet tool end; The utility model is simple in structure, and is easy to make, makes the user more laborsaving when rising jack, operates more convenient smoothness.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the diagram of work of traditional jack;

Fig. 2 is the diagram of work of the utility model preferred embodiment;

The specific embodiment

With reference to Fig. 2, the ratchet-type jack, comprise base 1, be installed in connecting rod mechanism 2 on the base 1, be installed in the pipe link upper end acrosome 4, be articulated in the screw rod 3 on the connecting rod mechanism 2 and be arranged on the connector 5 that screw rod 3 ends cooperate turning tool, it is characterized in that: the connector 5 of described screw rod 3 ends is provided with the polyhedron end 51 that cooperates with ratchet tool.

The polyhedron end 51 that is provided with on the connector 5 of screw rod 3 ends can have multiple shape, all can cooperate free wrench 6 instruments such as grade to realize rotating, but consideration difficulty of processing, the utility model is selected the polyhedron end 51 of regular hexahedron for use, can guarantee that so not only the connector end effectively engages with free wrench 6 instruments such as grade, and processing is easier, good looking appearance.

The operator makes when jack-uping weight, device socket polyhedron end 51 with free wrench 6 ratchet sleeves such as band such as grade, just rotatable screw rod 3 jack-up jacks, make rise more laborsaving, and instrument such as free wrench 6 can backwards rotation be adjusted socket position with polyhedron end 51 turning to any angle, make that the operator does not need free wrench 6 instruments such as grade are turned to the angle that is difficult to firmly, more do not need to plug repeatedly free wrench 6 instruments such as grade and contact with ground, improved the efficient of rising jack greatly to avoid tool end.

Embodiment of the present utility model is not confined to this, so long as the jack that cooperates with ratchet tool by polyhedron end 51 all belongs to protection domain of the present utility model.

Certainly, ratchet-type jack of the present utility model uses the manual ratchet tool except convenient, the polyhedron end 51 of connector 5 also makes things convenient for grafting electro-pneumatic or hydraulically operated turning tool, and do not need coupler of many preparations to connect turning tool and connector 5, avoided user's extraneous expense.

Claims

1, ratchet-type jack, comprise base (1), be installed in connecting rod mechanism (2) on the base (1), be installed in the pipe link upper end acrosome (4), be articulated in the screw rod (3) on the connecting rod mechanism (2) and be arranged on the connector (5) that screw rod (3) end cooperates turning tool, it is characterized in that: the connector (5) of described screw rod (3) end is provided with the polyhedron end (51) that cooperates with ratchet tool.

2, ratchet-type jack according to claim 1 is characterized in that: it is regular hexahedron that connector (5) is gone up the polyhedron end (51) that is provided with.
