[0003] When the cart is stopped, the casters need to be braked and fixed. At present, single-wheel brakes are used, that is, one brake mechanism is installed for each caster. In order to brake stably, multiple brake mechanisms need to be activated one by one. The operation is very cumbersome, especially when carrying When the cargo is heavy, starting the brake mechanism one by one is prone to slipping; on the other hand, due to the unreasonable structural design and unreasonable selection of materials, the brake contacts of the existing brake mechanism are severely worn and have a short service life. And the braking function cannot be started and released flexibly and lightly

Embodiment 1
[0034] Such as figure 1 , 2 As shown, a universal wheel brake device is disclosed in this embodiment. The universal wheel 1 is installed on the wheel frame 3 through a screw and a nut, and the top plate of the wheel frame 3 is provided with a mounting hole. The above universal wheel brake The device includes a rotary press brake assembly and a brake lever 2, the above rotary press brake assembly includes a base 4, a brake shaft 6, a rotary brake button 8, a brake spring 10 and a brake contact 12,
[0035] The above-mentioned base 4 is a columnar structure as a whole, part of which passes through the installation hole, and is fixed on the wheel frame 3 by nuts. The above-mentioned base 4 is provided with a central axis hole 14, and the central axis hole 14 penetrates the base 4 axially;
[0036] The above-mentioned brake shaft 6 is arranged in the central shaft hole 14, and can move up and down in the central shaft hole 14, and its outer wall is provided with a convex ring 16;...
Embodiment 2
[0050] Such as image 3 As shown, this implementation provides a dual-wheel synchronous braking system, including a brake lever 2 and two rotary push brake assemblies as in the first embodiment above, and the two rotary push brake assemblies mentioned above are all connected through their respective rotary brake buttons. 8 is connected to the brake lever 2, and the brake pedal 24 is arranged on the brake lever 2 between the two above-mentioned rotating and pressing brake assemblies.
[0051] The brake system with the above structure can realize one-lever synchronous double brakes, the operation is very convenient and simple, and at the same time, the problem of vehicle slipping in the prior art can be solved.
[0052] Certainly, according to actual use needs, also can design one bar synchronous multi-braking, one brake bar 2 controls the synchronous braking of three casters, four casters or even more casters.

Abstract
The invention provides a universal wheel braking device. The universal wheel braking device comprises a rotary pressing-type braking assembly and a brake lever, wherein the rotary pressing-type braking assembly comprises a base, a brake axle, a rotary braking button, a brake spring and a brake contact, the base is fixed on a wheel carrier, and a central axle hole is formed in the base; the brake axle is arranged in the central axle hole and can move up and down in the central axle hole, and a convex ring is arranged on the external wall of the brake axle; the rotary braking button is provided with an abutting contact and a central through hole into which the brake lever can penetrate; the abutting contact can be downwardly abutted against the brake axle through turning the brake lever; the brake spring axially sleeves the outer side of the brake axle, one end of the brake spring is connected onto the base, and the other end of the brake spring is abutted against the convex ring; the brake contact is connected to the bottom end of the brake axle. The rotary pressing-type braking assembly with an optimized structural design is matched with the brake lever, then, universal wheel braking or braking release can be very easily and flexibly started up, and the problem of wear of the brake contact can be overcome, so that the service life of the braking device is prolonged, and the use cost of the braking device is reduced.
Description
technical field [0001] The invention relates to a universal wheel brake device, and also relates to a double-wheel and multi-wheel brake system using the brake device, which can be popularized and applied to various logistics carts, mobile shelves and other equipment for installation and use. Background technique [0002] For the convenience of movement, casters are installed on the bottom of various carts and shelves. The casters are mainly divided into directional wheels and universal wheels. The directional wheels have a strong bearing capacity, but they cannot be turned flexibly; [0003] When the cart is stopped, the casters need to be braked and fixed. At present, single-wheel brakes are used, that is, one brake mechanism is installed for each caster. In order to brake stably, multiple brake mechanisms need to be activated one by one. The operation is very cumbersome, especially when carrying When the cargo is heavy, starting the brake mechanism one by one is prone to ...
