Description

Technical Field

[0001] This application relates to the field of caster technology, and more specifically, to an industrial caster brake bracket and caster. Background Technology

[0002] Caster brake brackets and casters are key mechanical components used for movement and braking in industrial, commercial, and household equipment. Casters are components installed at the bottom of equipment to support and enable movement, while caster brake brackets are braking devices installed on casters to limit the rotation of the rollers through mechanical structures.

[0003] In related technologies, for example, patent CN220763977U provides a caster brake bracket and caster. This device consists of a mounting plate, a bottom pivot rotatably connected to the center of the bottom of the mounting plate, and a frame coaxially connected to the bottom of the bottom pivot. An attachment rod is slidably mounted on the frame, and the attachment rod is vertically positioned. One end of the attachment rod is located above the frame and has an inner sliding plate welded to it. An extension pedal is welded to the end of the inner sliding plate away from the attachment rod. The other end of the attachment rod is located below the frame and is connected to a piston block. A protective sleeve is welded to the bottom wall of the frame, and a spring is fixedly connected to the bottom wall of the frame inside the protective sleeve. The bottom end of the spring is fixedly connected to the piston block, and a cutting plate is welded to the bottom wall of the piston block. This caster brake bracket and caster allow the roller to stop immediately when the cutting plate is inserted into the tooth groove, effectively reducing the braking distance and improving the braking effect of the caster brake bracket.

[0004] While the existing technical solutions described above can immediately stop the roller by inserting the cutting plate into the tooth groove, effectively reducing the braking distance, the caster frame is welded as a whole. When replacing the roller, it is necessary to disassemble the roller from the side extension plates on both sides. During disassembly, it is necessary to remove the bolts that pass through the roller shaft hole. During use, the bolts will cause varying degrees of wear to the roller shaft hole and the wheel frame, affecting the service life of the caster and making it difficult for the roller to adapt to heavy-duty working scenarios.

[0005] In view of this, we propose an industrial caster brake bracket and caster. Utility Model Content

[0006] The purpose of this application is to provide an industrial caster brake bracket and caster that can effectively solve the problem in the prior art that the rollers are difficult to disassemble and assemble through bolts in the shaft hole, making them unsuitable for heavy-duty working scenarios.

[0007] This application provides an industrial caster brake bracket, comprising:

[0008] Top plate, wherein side plates are symmetrically arranged at the bottom end of the top plate;

[0010] The braking mechanism is located on the outside of the brake disc and is used to brake the brake disc.

[0011] The brake disc has a sliding groove and a limiting groove on its inner side. A conical disc is slidably connected to the side wall of the sliding groove. A limiting block is symmetrically fixed to the side wall of the conical disc. A limiting block is slidably connected to the side wall of the limiting groove. Two bolts are threaded to the inner side wall of the brake disc. Multiple sets of brake grooves are arranged in a circumferential array on the outer side wall of the brake disc.

The bottom end of the positioning frame is symmetrically provided with guide grooves. A brake rod is provided on the side wall of the guide groove and is slidably connected to the guide groove. One end of the brake rod is provided with an elastic component. The elastic component is driven by an external force to make the two brake rods slide in opposite directions along the guide groove.

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0018] (1) This application adopts a detachable coaxial connection between the conical disc and the roller, so that the roller and the conical disc can jointly bear the load. The brake disc is always rotated and set on the side plate, so that the caster brake frame can bear the load together. Therefore, it effectively solves the problem that the roller is difficult to adapt to heavy-duty caster working scenarios by disassembling and assembling through the bolt in the shaft hole. Thus, it enables the roller to adapt to heavy-duty working scenarios and facilitates coaxial installation and disassembly.

[0019] (2) This application achieves the braking clamping effect on the brake discs on both sides by sliding along the groove track of the guide groove under the drive of external power on the outer side of the two brake rods.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 , Figure 2 and Figure 4This application discloses an industrial caster brake bracket and caster. The industrial caster brake bracket includes a top plate 1, two brake discs 2 and a brake mechanism 4. Side plates 11 are symmetrically arranged at the bottom end of the top plate 1. The two brake discs 2 are rotatably arranged on the side of the two side plates 11 that are close to each other. The brake mechanism 4 is arranged on the outside of the top plate 1 and is used to brake the brake discs 2. The inner side of the brake disc 2 is provided with a sliding groove 21 and a limiting groove 23. A conical disc 22 is slidably connected to the side wall of the sliding groove 21. A limiting block 24 is fixedly connected to the side wall of the conical disc 22. The limiting block 24 is slidably arranged inside the limiting groove 23. Two bolts 25 are threadedly connected to the inner side wall of the brake disc 2.

[0028] The casters include rollers 3, and the rollers 3 have conical grooves 31 on both sides corresponding to the conical discs 22 for coaxial installation and positioning.

[0029] First, the brake frame is connected via the top plate 1, side plate 11, and brake disc 2. During the disassembly of the roller 3, the bolt 25 is first turned outwards to disengage it from the brake disc 2. Then, the side plate 11 is manually pried out to one side, causing the brake disc 2 to move in the same direction. This widens the distance between the two brake discs 2, allowing the roller 3 to be removed, completing the disassembly. During the installation of the roller 3, it is first placed between the two brake discs 2, ensuring it is coaxial with them. Then, the bolts 25 on both sides are threaded onto the brake discs 2. During this process, as the bolts 25 penetrate deeper, their ends act on the conical disc 22, applying a pushing force. The conical disc 22 then slides horizontally along the axial direction of the groove 21, while simultaneously engaging the limiting block 2 via the limiting groove 23. The limiting effect of 4 prevents the conical disc 22 from shaking, allowing it to move horizontally in the axial direction. The sliding of the two conical discs 22 on both sides achieves the conical coaxial clamping and fixing of the roller 3. During the use of the equipment, the force on the roller 3 is transmitted to the limiting block 24 through the conical disc 22, and then to the brake disc 2 through the limiting block 24, realizing the coaxial rotation of the roller 3 and the brake disc 2, completing the installation operation. During the use of the equipment, the coaxial rotation of the roller 3 and the brake disc 2 realizes the movement of the equipment. At the same time, the braking effect of the brake disc 2 is achieved through the brake mechanism 4, thereby completing the braking operation of the roller 3. When the conical disc 22 slides horizontally along the axial direction of the slide groove 21, the conical disc 22 is inserted into the conical groove 31 and fits against it, completing the axial connection between the roller 3 and the brake disc 2.

[0030] Reference Figure 2 and Figure 3 The braking mechanism 4 includes a positioning frame 41, which is fixedly connected to the side plate 11. The bottom end of the positioning frame 41 is symmetrically provided with guide grooves 42. A brake rod 43 is slidably provided on the side wall of the guide groove 42. An elastic component 44 is provided at one end of the brake rod 43. The elastic component 44 is driven by an external force to make the two brake rods 43 slide in opposite directions along the guide groove 42.

[0031] Among them, the outer wall of the brake disc 2 is provided with brake grooves 26 in a circular array, and the brake grooves 26 cooperate with the brake lever 43.

[0032] Driven by external power, the brake levers 43 on both sides slide along the groove track of the guide groove 42. When the ends of the brake levers 43 on both sides slide into the brake groove 26, the brake clamping effect on the brake discs 2 on both sides is achieved, thereby completing the braking operation of the roller 3.

[0033] Reference Figure 2 The elastic component 44 is fixedly connected to a clamping rod 45 at the end away from the brake lever 43. A guide plate 46 is provided at the top of the clamping rod 45. The clamping rod 45 is slidably connected to the inner side of the guide plate 46. A guide hole for slidably connecting the clamping rod 45 is provided on the inner side of the guide plate 46. A push-pull plate 47 is fixedly connected to the top of the guide plate 46. The push-pull plate 47 is slidably disposed on the inner side of the top plate 1.

[0034] As the push-pull plate 47 is pushed into the top plate 1, the guide plate 46 slides along the push-pull plate 47. At the same time, the clamping rod 45 slides along the groove of the guide plate 46, shortening the distance between the bolts 25 on both sides to achieve a clamping effect. This provides power for the clamping movement of the brake rods 43 on both sides. At the same time, by pulling the push-pull plate 47 outward, the distance between the clamping rods 45 on both sides is widened, causing the brake rod 43 to slide out of the brake groove 26, thus releasing the clamping effect.

[0035] Reference Figure 5 The elastic component 44 includes a connector 441, which is fixedly connected to the brake lever 43. A slide rod 442 is fixedly connected to the end of the connector 441. The end of the slide rod 442 away from the connector 441 is slidably connected to the clamping rod 45. A spring 443 is provided on the outside of the slide rod 442, and the spring 443 is located between the connector 441 and the clamping rod 45.

[0036] During the clamping process of the clamping rod 45 driving the brake rod 43 to move and clamp, the slide rod 442 first slides into the clamping rod 45. When the sliding distance of the clamping rod 45 reaches its maximum value, the spring 443 is compressed due to the internal space limitation of the clamping rod 45. When the brake rod 43 is inserted into the brake groove 26, the spring 443 generates a rebound force acting on the brake rod 43, providing power for the clamping of the brake rod 43. At the same time, when the push-pull plate 47 is pulled outward, if the pulling force is greater than the clamping force of the spring, the brake rod 43 can be driven to slide out, canceling the power source and releasing the clamping effect.

[0037] Reference Figure 1 A connecting frame 5 is fixed to the top of the top plate 1 for connecting the load-bearing tool.

[0038] The pre-set mounting holes on the connector 5 facilitate quick matching and installation with mobile devices of different specifications, simplifying the installation process and improving installation flexibility.

[0039] In summary, when using the industrial caster brake bracket and caster disclosed in this application, firstly, the bolt 25 is turned outward to disengage it from the brake disc 2. Then, the side plate 11 is manually pried out to one side, causing the brake disc 2 to move in the same direction. At this time, the distance between the two brake discs 2 is increased, allowing the roller 3 to be removed, completing the disassembly operation. During the installation of the roller 3, the roller 3 is first placed between the two brake discs 2, keeping it coaxial with the brake disc 2. Subsequently, the bolts 25 on both sides are threaded onto the brake disc 2. During this process, as the bolts 25 are inserted, their ends act on the conical disc 22, applying a pushing force. At this time, the conical disc 22 moves along the axis of the groove 21. The roller 3 slides horizontally, and the limiting groove 23 limits the limiting block 24, preventing the conical disc 22 from shaking and allowing it to move axially horizontally. The sliding of the two conical discs 22 achieves conical coaxial clamping and fixation of the roller 3. During use, the force on the roller 3 is transmitted through the conical disc 22 to the limiting block 24, and then through the limiting block 24 to the brake disc 2, achieving coaxial rotation of the roller 3 and the brake disc 2, completing the installation operation. During use, the coaxial rotation of the roller 3 and the brake disc 2 enables the equipment to move, while the braking mechanism 4 achieves the braking effect on the brake disc 2, thus completing the braking operation of the roller 3. The brake levers 43 on both sides are on the outside. Driven by the power unit, the rollers slide along the groove of the guide groove 42. When the ends of the brake rods 43 on both sides slide into the brake groove 26, they achieve the braking clamping effect on the brake discs 2 on both sides, thus completing the braking operation of the rollers 3. When the push-pull plate 47 is pushed to slide into the top plate 1, the guide plate 46 slides along the push-pull plate 47. At the same time, the clamping rod 45 slides along the groove of the guide plate 46, shortening the distance between the bolts 25 on both sides to achieve the clamping effect, thereby providing power for the clamping movement of the brake rods 43 on both sides. At the same time, by pulling the push-pull plate 47 outward, the distance between the clamping rods 45 on both sides is widened, causing the brake rods 43 to slide out of the brake groove 26, thus releasing the clamping effect. During the clamping process of the brake lever 43 moving, the slide bar 442 first slides into the clamping bar 45. When the sliding distance of the clamping bar 45 reaches its maximum value, the spring 443 is compressed due to the internal space limitation of the clamping bar 45. When the brake lever 43 is inserted into the brake groove 26, the spring 443 generates a rebound force on the brake lever 43, providing power for the clamping of the brake lever 43. At the same time, when the push-pull plate 47 is pulled outward, if the pulling force is greater than the clamping force of the spring, the brake lever 43 can be driven to slide out, canceling the power source and releasing the clamping effect. Through the preset installation holes of the connecting bracket 5, it is easy to quickly match and install with mobile devices of different specifications, simplifying the installation process and improving the flexibility of installation adaptation.
