Self-locking cart driven by friction

Abstract

The invention belongs to the field of self-locking carts, and particularly relates to a self-locking cart driven by friction. The self-locking cart driven by friction comprises universal wheels, a bearing box, a handrail and brake wheel mechanisms. When people use the self-locking cart, when the cart stops, a first mounting block installed on the cart can rotate under the action of the a corresponding extension spring; the rotation of the first mounting block turns brake wheels into rolling friction with the ground, that is to reduce the friction loss of the brake wheels; at the same time, thebrake wheels and a second walking wheel are perpendicular to each other through the movement of the first mounting block, namely self-locking of the cart is realized; and the cart is prevented from starting again after stopping and affecting other things.

Description

Technical field [0001] The invention belongs to the technical field of self-locking carts, in particular to a friction-driven self-locking cart. Background technique [0002] A cart is a device used by an operator to transport a load. The operator needs to push the cart to move during use; however, if something needs to be stopped during the pushing process, the cart needs to be temporarily parked, and the cart needs to be in a static state; but when the push cart When the cart is loaded with heavy goods, it is difficult to park the cart; even if it is parked, it is very likely that the cart will automatically slip when it is subjected to a small external force; The items inside may also cause damage; so it is very necessary to design a cart that can lock itself after the cart stops. [0003] The present invention designs a self-locking trolley based on friction drive to solve the above problems. Contents of the invention [0004] In order to solve the above-mentioned d...
