CN2327672Y - Jack with improved structure - Google Patents

Abstract

The utility model provides a jack with an improved structure, particularly a structure that a rocking arm and a rocking arm of the utility model form a fixed connection and are pivoted in a main body. One end of the rocking arm shaft is provided with a through hole structure, and a convex shaft at the tail end of a handle pipe drives the rocking arm to rise in a swinging mode when the convex shaft is inserted into the through hole; a top disk can quickly rise to the precalculated position, thereby, the operating time is saved.

Description

A kind of jack that improves structure

The utility model relates to a kind of device that loaded article is risen, and refers to a kind of jack especially.

Jack is one of laborsaving instrument of inventing for the problem that solves shortage of manpower, using can the load that rises by the binding of oil pressure fit structure, reach the definite benefit in labour-saving, so the general wide property of using is splendid, such as at the indispensable instrument that just belongs among the automobile in the maintenance, yet the user all knows; Owing to jack is to utilize the process of waving of handle pipe to import oil pressure to oil hydraulic cylinder, make oil hydraulic cylinder promote the rocking arm lifting of pivot joint state again and produce the effect that rises (this rocking arm upper end articulates mutually with rocker shaft, body, the lower end then is to articulate with oil hydraulic cylinder), so the ascending velocity of rocking arm is very slowly in fact, therefore following disappearance is arranged just in use:

Since the use of jack be must when on the rocking arm take over a business to be contacted with below the load time, can drive load by the propelling of oil hydraulic cylinder rises, otherwise the action that rises before contact all is only to belong to not performance to rise the idle travel of effect, yet the bottom of load often all and ground have quite high height (high) as there being two, 30 centimeters between car chassis and ground approximately, so when the user drives rocking arm and rises to the load below in the swing mode of handle pipe; Usually all must expend appreciiable time and strength, not only be helpless to the process that rises of load, and make so-called labor-saving effect have a greatly reduced quality.

This creator is in view of above-mentioned every disappearance, feeling existing jack deeply fails to be improved at existing structure problem really in the creation design, so that non-on structure effectiveness is good, therefore satisfy with it and be engaged in creation design-calculated specialty manufacturing experience for many years, actively research and development improvement, under the discretion of each side's condition is considered, start out the composition of this structure finally, can solve every problem of existing jack fully.

Be time and the application of force waste that main purpose of the present utility model is to provide a kind of idle travel of preventing fast, have save time, the labour-saving characteristic, " the improving the jack of structure " that can solve the disappearance of usual means.

For realizing above-mentioned purpose, a kind of jack that improves structure of the utility model, mainly formed by body and rocking arm, it is characterized in that: be to be affixed state and to articulate between rocking arm and the rocker shaft with body, and rocker shaft one end is provided with the structure of perforation, the end of body rear handle pipe then is to be provided with protruding axle, the protruding axle that can directly make the handle pipe is cooperated with perforation and through swing process with drive rocking arm rotational positioning, and after the handle pipe resets, via the handle pipe load is risen again, reached jack operation purpose capable of rapid positioning.

The utility model adopts the jack of this kind improvement structure that technique scheme provided, be affixed and be hubbed at intrinsic composition by rocking arm and rocker shaft, and the perforation that rocker shaft one end is set up can provide the user to reach following benefit after enforcement for the protruding design that give the application of force and drive of handle pipe:

Because the rocking arm of jack of the present utility model is to be affixed design with rocker shaft, and rocker shaft one end is provided with the design of perforation in addition, handle pipe end then is to have protruding axle construction, so when the bottom of load has higher height, can be directly insert in the perforation with the direct application of force of swing mode with the protruding axle of handle pipe end, make rocking arm that quick lifting reaches the location along with the rotation of rocker shaft, this moment user's application of force on body that just can again the handle pipe be resetted, use the time and the application of force waste of the idle travel of preventing fast, reaching jack operation has and saves time, the labour-saving characteristic, the solution dust head prolongs the disappearance with existing project organization.

For enabling to understand really the function and benefit that structure of the present utility model is formed and can be reached, conjunction with figs. is enumerated embodiment now, introduces explanation as back in detail:

Description of drawings:

Fig. 1: be constructional drawing of the present utility model;

Fig. 2: be composition view of the present utility model;

Fig. 3: be enforcement scheme drawing of the present utility model;

Fig. 4: the action diagram that is jack interior oil cylinder pressure.

The drawing reference numeral explanation:

1 ... body 11 ... the handle pipe

12 ... protruding axle 13 ... the oil pressure button

2 ... rocking arm 21 ... rocker shaft

22 ... perforation 23 ... take over a business

10 ... jack

The utility model is a kind of jack that improves structure, mainly formed (as shown in Figure 1 and Figure 2) by body 1 and rocking arm 2, wherein: be to be affixed state and to articulate between rocking arm 2 and the rocker shaft 21 with body 1, and rocker shaft 21 1 ends are provided with the structure of perforation 22, and the end of body 1 rear handle pipe 11 then is protruding design with protruding axle 12.

By above-mentioned member, this jack 10 is inserted the solid application of force and can be earlier the protruding axle 12 of handle pipe 11 be moved to perforation 22 places when using, by the swing of handle pipe 11 directly drive rocker shaft 21, rocking arm 2 turns to the location (as shown in Figure 3, Figure 4; Wherein Fig. 4 is subjected to the action signal constitution diagram of rocking arm 2 tractions for the oil compression rod of oil hydraulic cylinder, be that oil compression rod keeps can continuing under the normal air-tight state to protrude out at hydraulic oil, and do not worry taking place the stressed phenomenon that can withdrawal of oil compression rod), again handle pipe 11 is resetted, can drive rocking arm 2 lasting risings of jack 10 by handle pipe 11, order is taken over a business 23 load is risen, and reaches quick location and laborsaving, time-saving operational benefits, can finish folding and also only need oil pressure button 13 opened when unclasping.

Claims (1)

1. A kind of jack that improves structure, mainly formed by body and rocking arm, it is characterized in that: be to be affixed state and to articulate between rocking arm and the rocker shaft with body, and rocker shaft one end is provided with the structure of perforation, and the end of body rear handle pipe then is to be provided with to make this handle pipe can directly utilize the protruding axle that drives the rocking arm rotational positioning in its perforation that inserts rocker shaft.
