Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the prior art, the spare tire of many special vehicles is suspended outside the vehicle, occupying the external space of the vehicle, while placing the tire inside the vehicle body lacks corresponding fixing measures, which easily causes shaking during vehicle operation. In order to improve the shortcomings, this utility model provides an in-vehicle fixing assembly for the spare tire of special vehicles.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An in-vehicle fixing assembly for a spare tire of a special vehicle includes a polygonal fixing seat. Several slide rails are arranged radially on the upper surface of the fixing seat's edge, with each slide rail radiating outwards from the central axis of the fixing seat. An L-shaped seat is slidably connected to each slide rail. The horizontal section of the L-shaped seat is slidably connected to the slide rail. A linkage plate is hinged to the lower end of the vertical section of the L-shaped seat. An electric push cylinder is fixed to the lower surface of the fixing seat. A moving plate is connected to the free end of the piston rod of the electric push cylinder. A U-shaped seat is integrally formed on the side of each moving plate located below the L-shaped seat. The free end of the linkage plate is located between the two ear plate sections of the U-shaped seat and is hinged to the U-shaped seat. A clamp for holding the spare tire is connected to the upper surface of the horizontal section of the L-shaped seat.

[0007] Compared with the prior art, the beneficial effects of this utility model are: due to the cooperative arrangement of the L-shaped seat, the linkage plate and the U-shaped seat, by controlling the extension and retraction of the electric push cylinder piston rod, the clamps can be tightened and opened, thereby fixing spare tires of different diameters and avoiding the spare tires from hanging outside the vehicle and occupying external space. This device is suitable for industrial production and has strong practicality.

[0008] As a preferred embodiment, a fixing panel is integrally provided at the edge of the fixing seat, the upper end of the fixing panel protrudes from the upper surface of the fixing seat, and an L-shaped plate is connected to the fixing panel, the horizontal section of the L-shaped plate being fixedly connected to the interior of the special vehicle.

[0015] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-2 As shown, this is an in-vehicle fixing assembly for a spare tire of a special vehicle. It includes a polygonal fixing seat 1. Several slide rails 2 are provided on the upper surface of the edge of the fixing seat 1. Each slide rail 2 is radially distributed with the central axis of the fixing seat 1 as the center line. Each slide rail 2 is slidably connected to an L-shaped seat 3. The horizontal section of the L-shaped seat 3 is slidably connected to the slide rail 2. The lower end of the vertical section of the L-shaped seat 3 is hinged to a linkage plate 4. An electric push cylinder 5 is fixed on the lower surface of the fixing seat 1. The free end of the piston rod of the electric push cylinder 5 is connected to a moving plate 6. A U-shaped seat 7 is integrally provided on the side of the moving plate 6 located below each L-shaped seat 3. The free end of the linkage plate 4 is located between the two ear plate sections of the U-shaped seat 7 and is hinged to the U-shaped seat 7. The upper surface of the horizontal section of the L-shaped seat 3 is connected to a clamp 8 for holding the spare tire. A fixing panel 9 is integrally formed at the edge of the fixing base 1. The upper end of the fixing panel 9 protrudes from the upper surface of the fixing base 1. An L-shaped plate 10 is connected to the fixing panel 9, and the horizontal section of the L-shaped plate 10 is fixedly connected to the interior of the special vehicle. The gripper 8 is L-shaped. A countersunk hole is formed on the upper surface of the horizontal section of the gripper 8, and a connecting bolt 11 is inserted into the countersunk hole. The gripper 8 is connected to the L-shaped base 3 via the connecting bolt 11. A groove 801 is formed on the inner surface of the vertical section of the gripper 8 to fit the outer surface of the spare tire. The groove 801 makes the gripper 8 fit more tightly with the spare tire and avoids scratches on the outer surface of the spare tire from the edge of the gripper 8. A slider 12 is connected to the lower end of the horizontal section of the L-shaped base 3. The slider 12 is slidably connected to the slide rail 2. The fixing base 1 is square. An extension plate 101 is integrally formed at each corner of the fixing base 1. One end of the slide rail 2 is fixed to the upper surface of the extension plate 101, and the other end extends into the fixing base 1.

[0017] During operation, the operator controls the electric push cylinder 5 to move the moving plate 6 vertically downwards, and the U-shaped seat 7 moves downwards simultaneously. At this time, the upper end of the linkage plate 4 rotates towards the fixed seat 1, causing the L-shaped seat 3 to move along the slide rail 2 towards the inside of the fixed seat 1, thereby causing the gripper 8 to move towards the inside of the fixed seat 1, completing the fixed clamping of the spare tire. When the spare tire needs to be removed, the piston cylinder of the electric push cylinder 5 is controlled to move the moving plate 6 vertically upwards.

[0018] The entire device can be installed inside the cargo compartment of a special vehicle. A stepped cavity 13 can be opened inside the cargo compartment. The horizontal plate of the L-shaped plate 10 is connected to the step of the cavity 13 to complete the fixed installation of the entire assembly. After completion, a cover plate is placed on the opening of the cavity 13.
