Description

[Technical field]

[0001] The utility model relates to the field of wheel hub decoration, in particular to an anti-dropping wheel hub center cover structure. [Background technology]

[0002] The automobile wheel hub decorative cover is arranged at the center of the wheel hub to decorate the wheel hub. Existing wheel hub decorative covers are generally fixed in the center ring of the wheel hub by the clamping feet on the decorative cover and the protrusions on the center ring of the wheel hub. For example, patent application number: 201821123228.X discloses a wheel hub decorative cover, the plastic body of the decorative cover includes a support cover and a plurality of clamping feet evenly distributed on the bottom edge of the support cover, and the decorative cover is assembled with the boss on the inner wall of the center ring through the clamping feet to fix the decorative cover in the center ring of the wheel hub. For example, patent application number: 202121597091.3 discloses a wheel hub decoration, and a group of elastic clamping feet that match the upper tolerance of the boss at the center hole of the wheel hub are respectively arranged on the wheel hub decorative cover body, and are clamped with the boss at the center hole through the protrusions on the clamping feet. However, the decorative cover is made of plastic, and the clamping feet will cause stress fatigue and lose the clamping elasticity due to long-term use. When the decorative cover rotates and vibrates at high speed with the wheel hub, the clamping feet that have lost their elasticity are prone to aging and fracture, and the decorative cover cannot be stably clamped on the wheel hub. When the wheel rotates and vibrates at high speed, the decorative cover is at risk of falling off.

[0003] The utility model is proposed in view of the deficiencies in the prior art. [Utility Model Content]

[0004] The utility model aims to overcome the above-mentioned shortcomings of the prior art and provides a hub center cover structure that prevents falling.

[0005] The utility model can be realized by the following technical solutions:

[0006] The utility model discloses an anti-drop wheel hub center cover structure, including a mounting plate, a plurality of clamping feet are fixed on the mounting plate, and fixing protrusions are fixed on the clamping feet. A limiting plate is also arranged on one side of the mounting plate, and a threaded tube is fixed on the limiting plate. A screw rod rotatably connected to the mounting plate is also arranged on the mounting plate, and the screw rod is threadedly connected to the threaded tube. A fixing block is also fixed on the screw rod, and a fixing groove is arranged on the fixing block. A panel is also arranged on the other side of the mounting plate, and a plurality of connecting devices are fixed on the panel. The connecting device includes two symmetrically arranged positioning plates, and positioning protrusions are fixed on the positioning plates. A positioning groove for the connecting device to pass through is also arranged on the mounting plate. When installing the center cover, push the mounting plate toward the center ring of the wheel hub. After the fixing protrusion on the clamping foot contacts the protrusion on the center ring, the clamping foot bends inward. After the fixing protrusion on the clamping foot separates from the protrusion on the center ring, the clamping foot returns to its natural state. The protrusion on the center ring is clamped on one side of the fixing protrusion on the clamping foot to fix the mounting plate in the center ring of the wheel hub. After the mounting plate is fixed, clamp it in the fixing groove of the fixing block with a screwdriver and rotate the fixing block. The screw rotates with the fixing block. When the screw rotates, the limit plate moves close to the mounting plate and moves into the clamping foot. The side supports the card foot. After the limit plate moves to the fixed protrusion position, the panel is fixed on the mounting plate. The connecting device on the panel passes through the positioning groove. After the positioning protrusion passes through the positioning groove, it is clamped on the mounting plates on both sides of the positioning groove to fix the panel, thereby realizing the installation of the hub center cover and the wheel hub. After the device is installed on the wheel hub, the card foot is supported by the limit plate to prevent the card foot from bending inward, thereby effectively preventing the fixed protrusion on the card foot from sliding off the protrusion at the center ring position of the wheel hub. When the wheel hub rotates at high speed, the hub center cover will not fall off the wheel hub.

[0007] Preferably, the mounting plate is also fixed with a plurality of limit rods, and the limit tubes are fixed on the limit plate at positions corresponding to the limit rods, and the ends of the limit rods are arranged in the limit tubes and are slidably connected to the limit tubes. The limit rods cooperate with the limit tubes to prevent the limit plate from rotating with the screw, and when the screw rotates, the limit plate moves in the direction of the screw.

[0008] Preferably, a positioning block is fixed on the panel and used in conjunction with the fixing groove. After the panel is fixed on the mounting plate, the positioning block on the panel is stuck in the fixing groove of the fixing block, which can effectively prevent the fixing block from rotating, thereby preventing the limit plate from moving and preventing the hub center cover from falling off.

[0009] Compared with the existing technology, the utility model has the following advantages:

[0010] After the device is installed on the wheel hub, the clamping foot is supported by the limit plate to prevent the clamping foot from bending inward, thereby effectively preventing the fixed protrusion on the clamping foot from sliding off the protrusion at the center circle position of the wheel hub. When the wheel hub rotates at high speed, the center cover of the wheel hub will not fall off the wheel hub.
