Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.It should be appreciated that herein
Described detailed description of the invention is merely to illustrate and explains this utility model, is not limited to this utility model.
This utility model provides a kind of spare tire lifting device, and this spare tire lifting device includes spare tyre lifter, relevant spare tyre
The concrete structure of the inside of lifter and operation principle, owing to being techniques well known, therefore omit detailed description thereof.
Described spare tyre lifter includes housing 1 and stretches out in the drive mechanism of housing 1 and for operating this drive mechanism
Rocking bar 5, wherein, drive mechanism drives the worm screw in spare tyre lifter to rotate lift spare tyre, and drive mechanism can be traditional
Arbitrary form, such as, gear mechanism, worm-and-wheel gear or other forms, will be described in detail this utility model below and adopt
The concrete form of drive mechanism.It addition, tool-free and detachably connected between rocking bar 5 and drive mechanism, say, that
Need operate drive mechanism with lifting spare tyre time, rocking bar 5 is connected to drive mechanism, when complete spare tyre lift work it
After, rocking bar 5 is disassembled, individually takes care of with spare tyre lifter, completely eliminate generation noise in vehicle travel process.This
Yet a further advantage is that when rocking bar 5 and drive mechanism connect of the rocking bar 5 of utility model, it is not necessary to use instrument, will to this
Described in detail below.
Specifically, as shown in figures 1 and 3, drive mechanism of the present utility model includes connecting tube 2, and this connecting tube 2 stretches out in
The sidewall of housing 1 also has connector 9, and the connection end that the size and shape of this connector 9 is preferably with rocking bar 5 adapts, but
It is that this utility model is not limited to this.Additionally, the lightening grooves 4 that can also extend along the axial direction of connecting tube 2 in connecting tube 2, with
Reduce the weight of connecting tube 2 and save material.The connection end of rocking bar 5 inserts connector 9 releasable and tool-freely, and shakes
The end that connects of bar 5 is connected to the connector 9 of connecting tube 2 by torque-transmitting mechanisms.Between connection end and the connecting tube 2 of rocking bar 5
Being that one is connected, the application cooperatively forms torque-transmitting mechanisms by between structure and the structure of connecting tube 2 of rocking bar 5,
The concrete form of torque-transmitting mechanisms can have a variety of, and this utility model provides two kinds of preferred implementations, specific as follows.
The first torque-transmitting mechanisms includes connection end and the connector 9 of connecting tube 2 of the rocking bar 5 of Forming Connection, specifically
Ground, rocking bar 5 can be formed as on-circular cross-section (such as ellipse, hexagon, square, nicked circle, triangle etc.)
Column-shape showering or conical surface body, the connector of connecting tube 2 can be formed as can being connected with the matching form conjunction of rocking bar 5, Forming Connection
Rocking bar 5 and connecting tube 2 convenient to disassembly.
It addition, as shown in Figure 1 to Figure 3, the second torque-transmitting mechanisms includes bearing pin 3 and is arranged on the connection end of rocking bar 5
On groove 6.
Bearing pin 3 extends and is fixed on connecting tube 2 along the radial direction of connecting tube 2 through connecting tube 2, and bearing pin 3 is preferably circle
Pin, but it is not limited to this, it is also possible to it is square pin.Furthermore it is preferred that bearing pin 3 is welded in connecting tube 2 so that bearing pin 3 with
Connecting tube 2 forms as one, but this utility model is not limited to this, the bearing pin 3 of the outside stretching into connecting tube 2 can be provided with solid
Determine hole, after bearing pin 3 passes connecting tube 2, this fixing hole inserts split pin to be fixed in connecting tube 2 by bearing pin 3.
Groove 6 is arranged on the connection end of rocking bar 5, and groove 6 extends along rocking bar 5 length direction and in the radial direction of rocking bar 5
Penetrating rocking bar 5, bearing pin 3 falls in groove 6.This groove 6 is preferably processing simple in-line groove as shown in Figure 2, and recessed
Groove 6 is sized to make bearing pin 3 fall in in-line groove, it is preferable that deep on the length direction of rocking bar 5 of groove 6
Radial dimension of one times of degree at least bearing pin 3, so that bearing pin 3 radially falls completely within groove 6.It is highly preferred that it is recessed
More than the radial dimension of twice of the groove 6 degree of depth bearing pin 3 on the length direction of rocking bar 5, it is ensured that rocking bar 5 during screwing with
Good connection between bearing pin 3.
Additionally, be provided with connecting the portion that screws 7 of screwing tool on the operating side relative with connecting end of rocking bar 5, as
Shown in Fig. 2 and Fig. 3, this screws portion 7 can be hexagonal flange, will be connected in the portion of screwing 7 such as screwing tools such as spanners to enter
Row torquing operations.Screw and can also be formed with the in-line that the length direction along rocking bar 5 extends in portion 7 and screw groove, thus out of office
Outer not such as screwing tools such as spanners time, the instrument replacement spanners such as bar can be used, insert a rod into this and screw in groove and screw
?.
Based on said structure, when needs carry out spare tyre lift work, rocking bar 5 is inserted to the connector 9 of connecting tube 2,
So that bearing pin 3 falls in the groove 6 of rocking bar 5, and the screwing tools such as spanner such as are used to screw the portion that screws 7 of rocking bar 5, then connecting tube
2 rotate along with the rotation of rocking bar 5, thus drive the worm screw within housing 1 being connected with connecting tube 2, thus carry out spare tyre liter
Fall operation, can be realized as assembling and tearing open by this simple motion of plug between rocking bar 5 of the present utility model and drive mechanism
Unload, disassembly process very simple and fast, and when not using rocking bar 5, rocking bar 5 can be taken care of individually at vehicle interior, from
And completely eliminate conventional noise.
It addition, as it is shown on figure 3, spare tire lifting device also includes keeper 8, this keeper 8 is arranged on the Rear frame of vehicle
On (not shown), this keeper 8 being provided with hole, location, rocking bar 5 can connect through location Kong Bingyu drive mechanism, thus
On rocking bar 5 formed two anchor points, it is ensured that rocking bar 5 during screwing without departing from home position.
Rocking bar 5 of the present utility model is used not only for spare tire lifting device, it is also possible to for jack.Jack has
Promoting socket and relief valve socket, the connection end of rocking bar 5 may be inserted in lifting socket, by repeating to press down the operation of rocking bar 5
The action of end, it is possible to rise jack；The in-line groove of rocking bar 5 can be connected with relief valve socket again, screws rocking bar 6 pre-
If during angle, it is possible to jack is carried out pressure discharge operations, so that jack declines, it follows that rocking bar of the present utility model 5
Application widely.
Preferred implementation of the present utility model is described in detail above in association with accompanying drawing, but, this utility model does not limit
Detail in above-mentioned embodiment, in technology concept of the present utility model, can be to skill of the present utility model
Art scheme carries out multiple simple variant, and these simple variant belong to protection domain of the present utility model.
It is further to note that each the concrete technical characteristic described in above-mentioned detailed description of the invention, at not lance
In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, this utility model is to respectively
Plant possible compound mode to illustrate the most separately.
Additionally, combination in any can also be carried out, as long as it is not disobeyed between various different embodiment of the present utility model
Carrying on the back thought of the present utility model, it should be considered as content disclosed in the utility model equally.
