Problems solved by technology
The existing double-branched car ladder with support rods is made of a steel bar, including a vertical support section and a bottom support section, and reinforcing ribs are also installed between the support section and the bottom support section. It is necessary to lift the vehicle to complete the ladder and support the car ladder, especially when the vehicle is loaded with goods, this kind of car ladder structure is more laborious
For this reason, the applicant has designed a "labor-saving double-car ladder", that is, "the front parts of the two bottom support sections that are transitioned to the two support sections are all symmetrically made into arcs", although "labor-saving" and "stable parking" have been solved. However, since the support section is made into an arc shape, the support strength of the ladder itself is greatly affected. Therefore, for electric bicycles and heavy-duty vehicles, it is easy to be deformed due to large external forces

Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0017] A high-strength support rod double-support car ladder, including the support section 1, the bottom support section 2 and the lock plate 4 of the car ladder, the installation flat iron 8 and the pin (no label), and the support section and the bottom support section use a steel bar The support section is set upright, the bottom support section is made into a W shape of rotation, the upper ends of the two support sections are made into the form of flat iron 6, and the inner sides of the flat iron made at the upper ends of the two support sections are fixed in parallel by pins. The installation flat iron is installed, the installation plate 7 of the car ladder is fixed in the gap between the instal...

The invention relates to a high-strength supporting rod dual-support box step. The box step comprises supporting sections, a bottom supporting section, a locking plate, installation strap iron pieces and pins, wherein the supporting sections and the bottom supporting section are formed by bending a reinforcing steel bar, inclined supporting frames are welded and fixed to the portions, close to the supporting sections, of the two sides of the middle portion of the bottom supporting section respectively, the two inclined supporting frames are arranged in a mirror symmetry mode, and the outer side of each inclined supporting frame is made to be in an arc shape. The supporting sections of the dual-support box step are still made to be of the straight supporting form so that the good supporting effect can be achieved; the inclined supporting frames can effectively improve the supporting capacity of the whole box step, pressure borne by the supporting sections of the box step is directly released to the supporting sections and the inclined supporting frames, the supporting performance of the box step is greatly improved, reinforcing ribs can be omitted for the box step due to the structure, and cost of the box step is greatly reduced.
Description
technical field [0001] The invention belongs to the field of bicycles or electric vehicles, and relates to a car ladder, in particular to a car ladder with two high-strength support rods. Background technique [0002] The car ladder is a tool for stabilizing and positioning bicycles and electric vehicles, including single car ladders and double car ladders. When using the vehicle, just put down the car ladder with your feet; when you stop using it, just use your feet to support the car ladder. For heavy-duty bicycles and electric vehicles due to their heavy weight, the car ladders used are mainly double car ladders, including flat iron car ladders and support rod car ladders. When people put down the car ladder and set up the car ladder, they need a lot of power to kick with the pedals. The existing double-branched car ladder with support rods is made of a steel bar, including a vertical support section and a bottom support section, and reinforcing ribs are also installed ...
