Problems solved by technology

[0002] In the prior art, the main wheel shaft seat is formed by die-casting of aluminum and cast steel, the cost of materials is high, and machining by machine pliers is required, which is expensive in processing cost and heavy in weight
The existing main wheel shaft seat is generally connected to the stepped tripod by fasteners, and the fastener connection has unreliable factors that are easy to loosen. Therefore, some main wheel shaft seats are fixed to the tripod by welding, especially spot welding, and the spot welding connection Although it is a relatively strong connection form, the appearance of the spot welding spot is irregular and unsightly. After the aluminum plate is spot welded, it needs to be electroplated or painted to make up for the defect that the spot welding damages the corrosion resistance of the aluminum plate.

Embodiment

[0020] Example: such as Figure 1 to Figure 4 As shown, a connection structure between a stepped tripod and the main wheel shaft seat includes a tripod 1 and a main wheel shaft seat 2. The main wheel shaft seat 2 is vertically turned outward at one axial end and extends to form a flange 3. The flange 3 There is a stamping protrusion 4 on the side facing the tripod 1, and the tripod 1 is provided with a stamping concave groove 5 engaged with the stamping protrusion 4.

[0021] The groove bottom of the stamped concave joint groove 5 is wider than the slot opening, and the stamped convex joint part 4 fills and connects in the stamped concave joint groove 5 in a corresponding shape.

[0022] Both the tripod and the main wheel axle seat are stamped from steel plates, and the stamped concave groove 5 and the stamped convex joint 4 are pressed against the flat surface of the flange 3 of the main wheel axle seat 2 and the flat surface of the tripod 1. form.

[0023] The flange 3 of ...

Abstract

The invention discloses a connection structure of a step tripod and a main wheel axle seat, which comprises a tripod and a main wheel axle seat, wherein one axial end of the main wheel axle seat is vertically turned out and extends to form a flange, a stamping convex-connecting part is arranged at one side of the flange facing to the tripod, and a stamping concave groove fixed with the stamping convex-connecting part in an occluded manner is arranged on the tripod. The invention has the advantages of high bonding strength, simple processing process and saved production cost.

Description

technical field [0001] The invention relates to a connection structure between a step tripod and a main wheel shaft seat, in particular to a connection structure between a light escalator step tripod and a main wheel shaft seat. Background technique [0002] In the prior art, the main wheel shaft seat is formed by die-casting of aluminum and cast steel, and the material cost is high, and machining by a machine tool is required, which is expensive in machining cost and heavy in weight. The existing main wheel shaft seat is generally connected to the stepped tripod by fasteners, and the fastener connection has unreliable factors that are easy to loosen. Therefore, some main wheel shaft seats are fixed to the tripod by welding, especially spot welding, and the spot welding connection Although it is a relatively strong connection form, the appearance of spot welding joints is irregular and unsightly. After the aluminum plate is spot welded, it needs to be electroplated or painte...
