Description

Technical Field

[0001] The utility model relates to the technical field of brake casters, in particular to a medium and heavy brake caster device. Background Art

[0002] Braking casters are auxiliary locking components installed on casters when the casters are in a stationary state and the working object needs to be positioned. They are the brakes of the casters. Casters with brakes are called braking casters.

[0003] During the use of the brake caster, in order to ensure the stability of the objects supported and transported at the upper end, the wheel is fixed and its body is engaged or pressed to increase friction, so that the caster remains in a stationary and fixed state, so that the material supported by the caster can be stably stationary in a certain position. Because the wheel in the caster is mainly a circular structure, and the device for fixing and limiting the increased friction of the caster in the brake caster is relatively single and acts on the circular caster wheel surface, and then when the supporting material on the brake caster moves in the opposite direction of the brake caster fixing and limiting device, the brake caster has a good fixing and limiting effect, but when the supporting material on the brake caster moves in the direction of the brake caster fixing and limiting device, the brake caster can easily overcome the resistance of the fixing and limiting device, causing the brake caster wheel to rotate slowly, thereby affecting the stability of the brake caster supporting the transported material. Therefore, a medium and heavy-duty brake caster device is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a medium-to-heavy duty brake caster device to solve the problem that when the supported material on the brake caster moves toward the brake caster fixed restriction device, the brake caster easily overcomes the resistance of the fixed restriction device so that the brake caster wheel rotates slowly, thereby affecting the stability of the brake caster supporting the transported material.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A medium and heavy-duty brake caster device comprises a brake foot and a wheel, the inner side of the brake foot is fixedly connected to the wheel by a bolt and a nut, the outer side of the brake foot is slidably connected to a large wave plate by a first steel ball, the other side of the large wave plate is tightly attached to a movable bottom plate, the inner side of the movable bottom plate is slidably connected to a center rivet, the inner side of the brake foot is slidably connected to a toothed plate by a second steel ball, the inner side of the brake foot is fixedly connected to the first brake rivet, the outer side of the first brake rivet is tightly attached to a brake spring sheet, the outer side of the brake spring sheet is tightly attached to a pedal, the inner side of the pedal is provided with a second brake rivet, the inner side of the wheel is clamped and connected with a dust cover, the inner side of the pedal is rotatably connected to a transmission rod, the other side end of the transmission rod is fixedly connected to a fixed shaft, the outer side of the fixed shaft is slidably connected to a rotating drum, the end of one side of the fixed shaft away from the transmission rod is fixedly connected to a limiting plate, the outer side of the rotating drum is slidably connected to a vertical plate, the side of the vertical plate close to the center of the brake foot is fixedly connected to a rotating column, and the side of the vertical plate close to the center of the brake foot is fixedly connected to a rubber block.

[0007] Preferably, the movable bottom plate, the large wave plate and the toothed plate are fixedly connected by a central rivet, and the toothed plate is snap-connected to the brake spring piece.

[0008] Preferably, the brake spring piece part is in close contact with the brake foot, and the brake spring piece is arranged on the outside of the wheel.

[0009] Preferably, the side of the rubber clamping block close to the wheel is arc-shaped, and the rubber clamping block is arranged on the outer side of the wheel symmetrically away from the brake spring plate with respect to the vertical center line of the wheel.

[0010] Preferably, there are two vertical plates in total, which are symmetrically arranged on the outside of the brake foot, fixedly connected by rubber clamps, and have slide grooves on the inner sides of the vertical plates, in which the rotating drum slides.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides a brake spring piece, a pedal, a transmission rod, a fixed shaft, a rotating drum, a limit plate, a vertical plate, a rotating column and a rubber block. When the brake caster is used and the wheel is fixed and restricted, the pedal is pressed so that the pedal rotates around the second brake rivet and pushes the brake spring piece closely attached to it to press against the surface of the wheel. At the same time, the brake spring piece rotates closely against the first brake rivet, so that the brake spring piece engages with the toothed disc that controls the rotation of the brake foot, thereby controlling the rotation of the brake foot. The upwardly moving part of the pedal drives the transmission column connected to it to move, so that the transmission column drives the fixed shaft and the rotating drum to move in the slide groove on the inner side of the vertical plate, and controls the vertical plate to rotate in the brake foot through the rotating column so that the rubber block is tightly attached to the outer side of the wheel. This device can effectively prevent the supported material on the caster from moving toward the direction of the brake caster fixing restriction device. The brake caster overcomes the resistance of the fixed restriction device so that the brake caster wheel rotates slowly, thereby ensuring the stability of the brake caster supporting the transported material.

[0023] The movable bottom plate 7, the large wave plate 6 and the toothed plate 10 are fixedly connected by the central rivet 8, and the toothed plate 10 is engaged with the brake spring piece 12, so that the brake foot 1 drives the wheel 4 to rotate and adjust the moving direction; the brake spring piece 12 part is in close contact with the brake foot 1, and the brake spring piece 12 is arranged on the outside of the wheel 4, so as to fix and limit the rotation of the wheel 4; the side of the rubber clamp 22 close to the wheel 4 is arc-shaped, and the rubber clamp 22 is arranged on the outside of the wheel 4 symmetrically away from the brake spring piece 12 with the vertical center line of the wheel 4, so as to cooperate with the brake spring piece 12 to act on the outside of the wheel 4, thereby improving the effect of fixing and limiting the wheel 4; there are 2 vertical plates 20, and the vertical plates 20 are symmetrically arranged on the outside of the brake foot 1, and the vertical plates 20 are fixedly connected by the rubber clamp 22, and a slide groove is provided on the inner side of the vertical plate 20, and the rotating drum 18 slides in the slide groove provided on the inner side of the vertical plate 20, so as to control the movement of the vertical plate 20 so that the rubber clamp 22 acts on the wheel 4.

[0024] Working process: When the medium and heavy-duty brake caster is used and the wheel 4 in the brake caster needs to be fixed and restricted, the pedal 13 connected to the brake foot 1 through the second brake rivet 14 is pressed, so that the pedal 13 rotates around the outer side of the second brake rivet 14 fixedly connected to the inner side of the brake foot 1, and the pedal 13 moves downward so that the brake spring piece 12 closely attached to it rotates around the first brake rivet 11 fixedly connected to the inner side of the brake foot 1, and then the brake spring piece 12 part gradually clings to the wheel 4, and the brake spring piece 12 part closely attached to the brake foot 1 gradually approaches its overall plane, and at the same time, the brake spring piece 12 part gradually approaches the toothed disc 10 fixedly restricted by the center rivet 8 on the inner side of the brake foot 1, and is engaged with the toothed disc 10, so that the rotation of the brake foot 1 of the medium and heavy-duty brake caster can be restricted, and while one end of the pedal 13 moves downward, the other end moves upward, and during the movement of one end of the pedal 13 upward, it drives the transmission rod 16 connected to the inner side to move, and the transmission rod 16 is fixedly connected to the end perpendicular to each other away from the pedal 13.

The outer side of the fixed shaft 17 is slidably connected with a rotating drum 18. At the same time, a sliding groove is opened on the inner side of the vertical plate 20, and the transmission rod 16 moves smoothly in the sliding groove inside the vertical plate 20 through the fixed shaft 17 and the rotating drum 18 outside it. During the movement of the rotating drum 18 from one end of the sliding groove opened on the inner side of the vertical plate 20 to the other end, the vertical plate 20 gradually approaches the wheel 4, and the rubber block 22 between the two vertical plates 20 gradually clings to the outer side of the wheel 4. In this way, the rubber block 22 and the brake spring piece 12 are respectively arranged on both sides of the vertical center line of the wheel 4 and are tightly attached to the wheel 4, which can effectively prevent the support material on the brake caster from moving in the direction of the brake caster fixing restriction device. The brake caster overcomes the resistance of the fixed restriction device so that the brake caster wheel 4 rotates slowly, thereby ensuring the stability of the brake caster supporting the transported material.
