The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

fig. 1 is a schematic view of the overall structure of the present invention.

Fig. 2 is a schematic diagram of the three-dimensional structure of the present invention.

Detailed Description

The following description will be made in detail with reference to fig. 1-2.

Given by figures 1-2, the utility model adopts the following technical scheme: the utility model provides a spare tyre tilting mechanism for fire engine is right, includes mount pad 1, and 1 left side of mount pad articulates there is

upset arm

2, and 2 upper end detachable of upset arms are connected with the spare tyre, and upset arm 2 carries out wobbling structure as the center round it with 1 articulated shaft of mount pad.

The utility model discloses in, mount pad 1 adopts the welding of hollow rectangular pipe to form, the welding has the installation chassis 6 of four L types at 1 left side lower extreme of mount pad, the connecting hole has been seted up to the vertical face on installation chassis 6, thereby insert bolt group in the connecting hole with on the vehicle chassis upper beam that mount pad 1 is fixed, the fixed work of mount pad 1 has just so been accomplished, the spare tyre passes through bolt group and 2 dismantlements of upset arm and is connected, thereby accomplish receiving and releasing of spare tyre through the swing of upset arm 2, just so make things convenient for taking out and withdrawing of spare tyre.

A first connecting rod 3 is hinged to the mounting seat 1, the first connecting rod 3 is located on the right side of the turnover arm 2, a second connecting rod 4 is hinged to the upper end of the first connecting rod 3, and the second connecting rod 4 is hinged and fixed to the turnover arm 2.

The turnover arm 2, the first connecting rod 3 and the second connecting rod 4 form a four-bar linkage mechanism, and one of the four-bar linkage mechanism is driven to move, so that the turnover arm 2 can swing.

The mounting seat 1 is hinged with a telescopic rod 5, and the lower end of the telescopic rod 5 is rotatably connected with the hinged shaft of the first connecting rod 3 and the hinged shaft of the second connecting rod 4.

First connecting rod 3 and the coaxial round pin axle of second connecting rod 4 are articulated, the lower extreme and the round pin axle of telescopic link 5 rotate to be connected, thereby telescopic link 5 is flexible to promote first connecting rod 3 and the swing of second connecting rod 4, then drive upset arm 2 and swing, here, we do not adopt the mode of directly promoting the motion of upset arm 2, because if telescopic link 5 lower extreme is direct to articulate with upset arm 2, so telescopic link 5's corresponding meeting increase is a lot, the cost will improve a lot, adopt our foretell form, under the auxiliary action of first connecting rod 3 and second connecting rod 4, the stroke of choosing telescopic link 5 is less, the volume in cost has been reduced and the space has been saved.

The upper end of the left side of the mounting seat is fixed with a U-shaped clamping plate 7, and the lower end of the turnover arm 2 is arranged in the U-shaped clamping plate 7 to form a structure for limiting the movement of the turnover arm 2.

The utility model discloses in, upset arm 2 adopts steel sheet and round steel welding to form, and the card is in 7 departments of U type cardboard in 2 upper ends of upset arm, and first can play certain supporting role, reduces telescopic link 5's hand, connects and can also play certain limiting displacement, rocks around avoiding upset arm 2.

The disc 8 is fixed at the upper end of the turnover arm 2, and the spare tire is detachably connected with the disc 8 through a bolt group.

The telescopic rod 5 is a hydraulic cylinder.

The hydraulic mode is the most common mode on the automobile, and the swing of the turnover arm 2 is realized through the extension and contraction of the hydraulic cylinder, so that the spare tire is driven to move together.

The utility model discloses when using, through the flexible of pneumatic cylinder, under the assistance of first connecting rod 3 and second connecting rod 4 to drive upset arm 2 and overturn, conveniently take out and withdraw the spare tyre.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
