[0026] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1 , Figure 2 , Figure 3A side-brake caster is shown, comprising a caster body 1, wherein the caster body 1 comprises a mounting body 2, a rolling assembly 4 nested inside the mounting body 2 and connected thereto, and a brake assembly 3 located at one side of the mounting body 2 and connected to the mounting body 2 and the rolling assembly 4, the brake assembly 3 comprising a brake block 31 abutting against the mounting body 2, a pedal 32 located at one side of the brake block 31, and a fastening assembly 33 fixing the brake assembly 3 on the mounting body 2, the brake block 31 being connected to the pedal 32, and the pedal 32 drives the brake block 31 to approach or move away from the rolling assembly 4 when rotating, the pedal 32 is provided with a braking position and an unlocking position, when the pedal 32 is rotated to the braking position, the brake block 31 abuts against the rolling assembly 4 to form a limiting state, and when the pedal 32 is rotated to the unlocking position, the brake block 31 moves away from the rolling assembly 4 to form an unlocking state.

[0028] The utility model directly controls the contact between the brake shoe 31 and the rolling assembly 4 through the pedal 32, which simplifies the multiple linkage parts and complex component structures required for traditional brake casters while ensuring the braking effect. This setting not only makes the operation process more direct and convenient, but also reduces the complexity and cost of maintenance; further, the utility model utilizes a dead point locking mechanism to automatically lock the contact state between the brake shoe 31 and the rolling assembly 4 when the pedal 32 reaches the braking position, without relying on additional auxiliary components. This locking ensures stability and safety during braking. At the same time, when the equipment needs to be moved, simply turning the pedal 32 to the unlocked position can make the brake shoe 31 leave the rolling assembly 4, restore the rolling ability of the caster, and further enhance the convenience of operation.

[0029] Further, such as Figure 3 A side brake caster is shown, wherein the pedal 32 is provided with a second connecting hole 321 for the fastening assembly 33 to extend into, a guide rod 322 arranged at one end of the pedal 32 and a protruding foot step 323 arranged at the other end of the pedal 32, and the pedal 32 rotates around the second connecting hole 321.

[0030] In the utility model, the setting that the pedal 32 rotates around the second connecting hole 321 and the fixed setting of the guide rod 322 constitute an efficient braking and starting mechanism. The integrated welding of the guide rod 322 and the pedal 32 ensures a firm connection between the two. This structure not only improves the overall strength and durability, but also enhances the overall reliability of the braking system, and effectively avoids failures that may be caused by loose components; further, this setting provides a simple and direct way for the user to accurately control the position of the brake block 31 through the foot step 323 to achieve rapid braking or unlocking. The guide rod 322 acts as a force transmission element, ensuring that the rotation of the pedal 32 can be smoothly converted into the effective movement of the brake block 31, thereby making the braking process more precise and stable.

[0031] Further, such as Figure 1 and Figure 8 A side-brake caster is shown, wherein one end of the brake block 31 is provided with a brake surface 313 extending and protruding toward the rolling component 4, the lower surface of the brake surface 313 is an arc surface 3131 matching the surface contour of the rolling component 4, the brake surface 313 extends downward to form a first plane 314, a reinforcing rib 317 is provided between the brake surface 313 and the first plane 314, and the first plane 314 extends to form a second plane 316 through a transition curved surface 315.

[0032] The arcuate surface 3131 of the brake shoe 31 in the utility model matches the surface profile of the rolling assembly 4, and this arrangement ensures sufficient and uniform contact during braking, so that the braking force is more concentrated, the possibility of sliding is reduced, and the braking efficiency is improved; further, the arrangement of the reinforcing rib 317 not only enhances the overall structural strength of the brake shoe 31, but also ensures its stability and durability under repeated use and long-term load; further, the transition from the first plane 314 to the second plane 316 passes through an ingeniously designed transition surface 315, which not only provides the brake shoe 31 with the necessary movement space to avoid collision with the mounting body 2 during movement, but also ensures the smooth operation of the overall braking system.

[0033] Further, such as Figure 2 , Figure 3 The side brake caster shown in the figure has a brake block 31 with a first connecting hole 311 for the fastening assembly 33 to extend into, and a second guide groove 312 located at one end of the brake block 31, and the first connecting hole 311 is arranged as a long hole.

[0034] The long hole setting of the first connecting hole 311 in the utility model allows the brake block 31 to move freely in the vertical direction without being restricted by the fastening assembly 33, thereby ensuring that the brake block 31 can smoothly contact or leave the rolling assembly 4 as needed, thereby effectively achieving braking or unlocking, ensuring the efficiency of the braking process; further, the setting of the second guide groove 312 further ensures that the brake block 31 can move accurately along a predetermined path during the braking process, which not only enhances the accuracy of the braking operation, but also improves the reliability and consistency of the overall braking system.

[0035] Further, such as Figure 3 and Figure 8 A side brake caster is shown, wherein a limit point 3161 is provided at one end of the second guide groove 312, and an unlocking point 3163 is provided at the other end, a sliding interval 3162 is provided between the limit point 3161 and the unlocking point 3163, the sliding interval 3162 is a plane on the side close to the limit point 3161, and a curved surface on the side close to the unlocking point 3163, the second guide groove 312 is for the guide rod 322 to be inserted and move, and the pedal 32 rotates to drive the guide rod 322 to move in the second guide groove 312 to drive the brake block 31 to move.

[0036] In the present invention, the setting of the limit point 3161, the unlocking point 3163 and the sliding interval 3162 forms a clear path, which effectively guides the brake block 31 to perform smooth braking and unlocking actions. The sliding interval 3162 is designed as a plane on the side close to the limit point 3161, and is transformed into a curved surface on the side close to the unlocking point 3163. This setting ensures that the guide rod 322 can smoothly transition from the braking state to the unlocking state, or vice versa, during the movement process; further, the setting of the limit point 3161 and the unlocking point 3163 ensures that the brake block 31 can be quickly locked in the correct position when braking or releasing, avoiding movement or loosening, thereby enhancing the safety and reliability of the entire braking system.

[0037] Further, such as Figure 3 and Figure 4 A side brake caster is shown, wherein the mounting body 2 includes a bracket 21, and both ends of the bracket 21 are provided with mounting holes 211 for connecting with the brake assembly 3 and the rolling assembly 4, and a first guide groove 212 for the brake shoe 31 to extend into, and the first guide groove 212 is used to limit the movement direction of the brake shoe 31.

[0038] In the utility model, the cooperation of the first guide groove 212 and the transition curved surface 315 ensures that the brake block 31 moves along the specified path during operation, and also ensures that the caster can respond quickly and accurately when encountering emergency braking needs or performing regular parking, thereby achieving precise and effective braking.

[0039] Further, such as Figure 1 , Figure 2 and Figure 3 A side brake caster is shown, wherein the fastening assembly 33 includes a spacer sleeve 333 arranged in the first connecting hole 311 and the second connecting hole 321, and a first fastener 331 and a second fastener 332 for fixing the brake assembly 3 with the mounting body 2 and the rolling assembly 4 through the spacer sleeve 333, and a step is provided at one end of the spacer sleeve 333 that abuts against the first fastener 331, and the step is arranged in the shape of petals.

[0040] In the utility model, a petal-shaped step is provided at one end of the spacer sleeve 333 that contacts the first fastener 331. This arrangement not only provides a more stable contact surface, but also enhances the connection firmness between the spacer sleeve 333 and the first fastener 331. At the same time, the spacer sleeve 333 is provided with an appropriate gap when cooperating with the first connecting hole 311 and the second connecting hole 321, ensuring that even after the brake block 31 and the pedal 32 are firmly fixed, they can still perform necessary movement and rotation.

[0041] Further, such as Figure 1 , Figure 4 and Figure 7 The illustrated embodiment is a side brake caster, wherein the two ends of the bracket 21 are vertical plates, a distance is set between the vertical plates for the rolling assembly 4 to be embedded, the mounting hole 211 is located on the vertical plates, and the first plane 314 and the second plane 316 are respectively in contact with the two sides of the vertical plates.

[0042] In the utility model, the bracket 21 adopts a setting of vertical plates at both ends, wherein a specific distance is set between the vertical plates, providing a stable and precise installation space for the installation of the rolling component 4; further, the brake block 31 obtains a stable supporting surface through the close contact with the vertical plates by the first plane 314 and the second plane 316. This setting effectively avoids the swinging or deflection of the brake block 31 during braking, thereby ensuring the smoothness and reliability of the braking action.

[0043] Further, such as Figure 4 and Figure 5 A side brake caster is shown, wherein the rolling assembly 4 includes a roller 41, a bearing 42 nested inside the roller 41, and a first pressure plate 43 and a second pressure plate 44 located at both ends of the roller 41 for fixing the bearing 42, and the first pressure plate 43 and the second pressure plate 44 are both provided with a fixing hole 431 connected to the bracket 21.

[0044] The utility model installs a bearing 42 inside the roller 41 and further stabilizes the structure through a pressure plate connected to the bracket 21. This arrangement enhances the load-bearing capacity of the roller 41, allowing the side-brake caster to withstand a larger load without being easily damaged. Furthermore, the fixing hole 431 on the pressure plate provides a quick and easy installation method, which facilitates the maintenance or replacement of the rolling assembly 4 and ensures efficient and simple operation.

[0045] Further, such as Figure 1 and Figure 2 A side brake caster is shown, wherein the first fastener 331 passes through the brake assembly 3, the mounting body 2 and the rolling assembly 4 in sequence and is connected to the second fastener 332 by threading.

[0046] The fastening assembly 33 of the utility model is connected by threads, which better improves the overall performance and adjustability of the braking system and provides convenience and reliability for users.

[0047] Furthermore, if Figure 1 and Figure 2 A side brake caster is shown, wherein the mounting body 2 further comprises a first ball 22 and a first cover plate 24 arranged on the upper surface of the annular step at the upper end of the bracket 21, and a second ball 23 and a second cover plate 25 arranged on the lower surface of the annular step.

[0048] The utility model improves the rotation flexibility and stability of the caster by respectively configuring the first ball 22 and the second ball 23 and the corresponding cover plate on the annular steps at the upper and lower ends of the bracket 21. This structure enables the caster to maintain smooth rotation and excellent positioning ability while bearing the load, thereby enhancing the operational convenience and safety of use when the equipment is moved.

[0049] Furthermore, if Figure 3 and Figure 6 A side brake caster is shown, in which the foot step 323 is provided with unlocking and braking status markings for easy identification by the user.

[0050] like Figure 1 and Figure 2 As shown, the implementation method of this embodiment is as follows:

[0051] The user first installs the side brake casters under the required equipment, making sure each caster is firmly fixed so that the equipment can move smoothly. Once installed, the equipment is ready to be moved or fixed as needed.

[0052] When the device needs to be moved from one place to another, the user only needs to gently step on the pedal 32 to trigger the unlocking mechanism. During this process, the design of the pedal 32 ensures easy and intuitive operation. The pedal 32 accurately controls the movement of the brake block 31 through the built-in guide rod 322 and the second guide groove 312, so that it is lifted from the roller 41, eliminating the braking resistance. At this time, the device can be easily pushed to a new position. After reaching the predetermined position, the user activates the braking mechanism by stepping on the pedal 32 in the opposite direction to the braking position. This action makes the brake block 31 closely contact with the roller 41, forming a stable braking state.

[0053] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
