Description

A kind of mounting structure of automotive cutting type jack

Technical field

The structure of a kind of fixed object on the present invention relates on a kind of automobile is specifically related on automobile the structure of fixed installation automotive cutting type jack.

Background technology

The solid mode of existing automotive cutting type jack on automobile mainly contains: one, with band and support jack is fixed on gusset wheel hub bag accessory position; Two, directly jack is placed in the spare tyre wheel hub; Three, jack is placed on special-purpose the inside, tool box.The fixed form of mode one need take space in the baggage container, and needing increases band and support, and is also higher to the requirement of strength of support and band, and gusset wheel hub bag annex space was just little originally, was not very convenient when taking jack; If two-box automobile, gusset wheel hub bag space is littler, adopts this mode to arrange.The placement of mode two does not take trunk space, but owing to jack is not fixed, abnormal sound takes place easily when jolting the road surface.The fixed form of mode three is fixed, takes also easily, but cost is higher, and the material requirements height in tool box, otherwise the tool box damages easily.

Summary of the invention

Technical matters solved by the invention is: overcome the deficiencies in the prior art, a kind of fixed sturcture of shearing jack is provided, this jack fixing means does not take trunk space, with low cost and fixed, can not produce abnormal sound.

Technical scheme of the present invention is as follows:

A kind of fixed sturcture of automotive cutting type jack, it includes shearing jack and wheel support, and described wheel support is welded on the baggage compartment floor, is useful on first nut bore that installs and fixes spare tyre on the wheel support.

On this architecture basics, described fixed sturcture has also designed a clamping screw, and there is screw thread described clamping screw lower end, and there is limited step at the middle part;

Described wheel support is between jack screw mandrel and jack footstock, and wheel support is provided with second nut bore that is used to install and fix shearing jack;

That end that the rocking bar of described shearing jack cooperates with the hole of jack screw mandrel end stretches out one section spacing head vertical with the body of rod, and spacing head inserts in the hole of jack screw mandrel end, the rotation of restriction rocking bar.Rocking bar is horizontally placed between two arms of jack, is welded with pad at the rocking bar middle part, and there is through hole at the pad center, is used to provide the rocking bar attachment point, cooperates with screw rod, compresses jack by screw rod is screwed in wheel support.

Described clamping screw passes the pad center through hole, and second nut bore on lower end screw thread and the wheel support is connected, and the limited step at middle part is pressed on the pad.

This fixed sturcture directly utilizes present wheel support, by on wheel support, increasing a nut bore, set up a clamping screw again, simultaneously the rocking bar of jack is done some small changes, jack can be fixed, convenient fixing, and jack comes down to be arranged in the middle sinking space of wheel hub of spare tyre, do not take other space of automobile, therefore, this fixed sturcture has reasonable in design, easy to operate, fixed, can not produce abnormal sound, and not take the advantage of trunk space.

Description of drawings

Fig. 1 is the scheme drawing of this fixed sturcture.

Fig. 2 is the structural representation of rocking bar;

Fig. 3 is the structural representation of screw rod;

Fig. 4 is the structural representation of wheel support;

Among the figure, 1, rocking bar; 2, pad; 3, position-limited lever; 4, clamping screw; 5, limited step; 6, wheel support; 7A, first nut bore; 7B, second nut bore; 8, shearing jack; 9, jack footstock; 10, jack screw mandrel; 11, baggage compartment floor

The specific embodiment

Describe structure of the present invention in detail below in conjunction with accompanying drawing:

The fixed sturcture of automotive cutting type jack shown in Figure 1 includes on shearing jack 8, wheel support 6, the baggage compartment floor 11 and clamping screw 4.

In conjunction with shown in Figure 4, wheel support 6 roughly is " several " shape, is welded on the baggage compartment floor 11, and two nut bore are arranged on the top plan, and the first nut bore 7A is used for fixing spare tyre, and the second nut bore 7B is used for fixing shearing jack 8.

In conjunction with Fig. 2 as seen, this fixed sturcture need change the rocking bar 1 of jack, rocking bar 1 is roughly L-shaped, that end that rocking bar 1 cooperates in the hole with jack screw mandrel 10 ends stretches out a bit of vertical with the body of rod spacing 3, insert in for spacing 3 in the hole of jack screw mandrel 10 ends, with the rotation of restriction rocking bar 1.Rocking bar 1 is horizontally placed between two arms of shearing jack 8, is welded with pad 2 at rocking bar 1 middle part, and there is through hole at pad 2 centers, are used to provide the rocking bar attachment point, cooperates with clamping screw 4, compresses shearing jack 8 by clamping screw 4 is screwed in wheel support.

In conjunction with Fig. 3 as seen, there is screw thread clamping screw 4 lower ends, are used for cooperating with the second nut bore 7B on the wheel support 6, and there is limited step 5 at the middle part, and clamping screw 4 upper ends are "T"-shaped handle shape.

When installing and fixing, shearing jack 8 is placed near the wheel support 6, and allow wheel support 6 between jack screw mandrel 10 and footstock 9, pass, then spacing 3 of the rocking bar 1 of jack inserted in the hole of jack screw mandrel 10 1 ends, and be horizontally placed on two arms of shearing jack 8, pass the hole from rocking bar 1 middle part pad 2 with clamping screw 4 again, clamping screw 4 is tightened among the second nut bore 7B on the wheel support 6, thereby by rocking bar 1 jack 8 is pressed on the baggage compartment floor 11, reaches fixing.
