Problems solved by technology

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 slide automatically when it is subjected to a small external force; The items inside may also cause damage; so it is necessary to design a cart that can lock itself after the cart stops

specific Embodiment approach

[0060] Specific embodiments: when people use the cart designed by the present invention, when the cart stops, the first mounting block 35 installed on the cart is under the action of the corresponding tension spring 20, and the first mounting block 35 drives the corresponding The drive push rod 26 rotates towards the side away from the second road wheel 16 around the axis of the fixed ring sleeve 34; The air inlet 29, the second one-way air outlet 30 and the second air inlet 31 play a buffering effect on the drive push rod 26; the first mounting block 35 is rotated at a slower speed; preventing people from using it if Cart can lock automatically when stopping halfway and the time is shorter; Increase the loss of brake wheel mechanism 4; Make the service life of brake wheel mechanism 4 reduce; First installation block 35 rotation will drive fixed shaft 37 around fixed circle The axle center of ring sleeve 34 rotates; Fixed shaft 37 rotation will drive fixed axle sleeve 36 to ro...

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...
