structure

The overall capacity of the stretcher attachment is 20cm × 10cm × 3cm, mainly by the multi-directional wheel and stretcher carrying device welded together. Multi-directional runner for the diameter of 10cm solid urea round, not only strong and durable, and not easy to be sediment, grass leaves and other cards, can reduce the friction of sediment and improve its efficiency. 4 wheels are used multi-round, to ensure that the process of transporting the patient in the process of changing the direction according to the situation at any time to reduce the battlefield to distinguish between the front and rear wheel time, you can more quickly transported sick and wounded to safe areas, Sick and wounded get timely and effective treatment, to save the lives of sick and wounded. The stretcher-carrying device mainly comprises a U-shaped stretcher-bearing structure, a stretcher-catching bolt and a rotary handle. U-shaped stretcher bar bearing structure to the stretcher bar width is moderate, can be quickly installed on the stretcher; in the U-shaped groove and the bracket on the side of the opposite side of the nut with a transverse alveolar groove, easy to tighten the bolt when the groove And the friction of the stretcher; the friction rod of the stretcher bar is located inside the U-shaped slot and has a snap-on nut with a transverse alveot at one end and a significant increase in the interaction between the auxiliary device and the stretcher And the other end of the clamping bolt is a rotating handle, and the main purpose of the setting is to facilitate the rotation of the clamping bolt, and the locking bolt is provided with the other end of the clamping bolt, Quick adjustment of the tightness of the auxiliary device in combination with the stretcher.

Materials

The device according to the level of transport, the characteristics of the treatment of sick and wounded and the economic conditions of the comprehensive consideration, the choice of material, the need to have high strength, light weight, wear resistance, drop resistance and corrosion resistance of the performance, but also Have good water resistance and heat resistance.

In the choice of material on the wheel, should be consistent with the characteristics of easy to carry and corrosion-resistant. At present, multi-directional runner mainly polyurethane, cast iron, plastic and other materials. From the material performance point of view, cast iron durable, but bulky rust, and corrosion in the acid and alkali environment damage; plastic corrosion but easy to damage; and polyurethane has a high mechanical strength, good wear resistance, Oil resistance, wide range of hardness and good mechanical properties, so the choice of polyurethane solid wheel as the auxiliary device wheels. The material bearing the connection device mainly to stainless steel, can reach the general needs of the wounded transport strength, and the quality of light, but also to achieve drop resistance, heat and other requirements.
