Description

Technical Field

[0001] This utility model relates to the field of wheel braking device technology, specifically a brake device that is easy to adjust. Background Technology

[0002] Existing wheel brake systems are widely used in various vehicles and machinery, such as bicycles and hospital trolleys, achieving deceleration or braking through friction between the brake assembly and the wheel hub. However, over long-term use, the brake assembly gradually wears down, increasing the distance between it and the wheel hub. This leads to insufficient friction during braking, reduced braking effectiveness, and even the safety hazard of brake failure. To restore braking performance, it is usually necessary to adjust the position of the brake assembly to restore a proper distance from the wheel hub.

[0003] Most existing brake structures employ a fixed installation design. When brake components wear down, adjustments require disassembly or replacement of shims, which is cumbersome, time-consuming, and inefficient. Therefore, it is necessary to provide a simple, easily adjustable brake device that can quickly compensate for brake component wear without disassembling the brake system. This would ensure stable and reliable braking performance and extend the device's lifespan. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an easily adjustable braking device, aiming to solve problems such as the difficulty in adjusting wheel brake devices after wear in existing technologies, and to achieve rapid compensation adjustment of brake clearance, ensuring stable and reliable braking performance.

A braking assembly, which can be adjusted to rotate relative to the mounting base, is disposed on one side at a first angle. An anti-slip element is disposed on the side of the braking assembly away from the mounting base. An adjusting seat is disposed on the other side of the mounting base at a second angle. A through hole is formed on the adjusting seat. One side of the through hole opens towards the braking assembly. An internal thread is provided on the inner sidewall of the through hole. An external thread adapted to the internal thread is provided on the outer sidewall of the threaded fastener. The threaded fastener is installed into the through hole, and one end of the threaded fastener abuts against the braking assembly.

[0006] Preferably, the mounting base has a mounting hole in the middle.

[0007] Preferably, the brake assembly is a brake assembly with an arc, and the brake assembly has an abutting portion 26 protruding from the side facing the through hole.

[0008] Preferably, the mounting base has a triangular protrusion protruding upward on the side near the brake assembly, and the side of the triangular protrusion near the brake assembly is parallel to the brake assembly.

Detailed Implementation

[0018] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] See Figures 1-5 This embodiment provides an easily adjustable braking device, which includes a braking device body 1 and a threaded fastener.

[0020] The brake device body 1 described in this application includes a mounting base 10, which is used to install the brake system at a fixed position, such as the vehicle frame or support rod, as the mounting base for the entire brake mechanism. A brake assembly 20, which can be adjusted to rotate relative to the mounting base 10, is provided on one side of the mounting base 10 to generate braking force to achieve deceleration or stopping when force is applied. An anti-slip member 21 is provided on the side of the brake assembly 20 away from the mounting base 10. An adjusting seat 30 is provided on the other side of the mounting base 10 at a second angle. A through hole 40 is formed on the adjusting seat 30, with one side opening towards the brake assembly 20. An internal thread is provided on the inner wall of the through hole 40. An external thread adapted to the internal thread is provided on the outer wall of a threaded fastener. The threaded fastener is installed into the through hole 40, and one end of the threaded fastener abuts against the brake assembly 20. It should be noted that when the user rotates the threaded fastener, the threaded fastener can move back and forth along the axial direction of the through hole 40, thereby pushing or releasing the brake assembly 20, causing the brake assembly 20 to have a slight displacement relative to the wheel hub. Specifically, when the threaded fastener is tightened, the threaded fastener will push the brake assembly 20 forward, thereby causing the brake assembly 20 to move closer to the wheel hub. When the threaded fastener is loosened, the distance that the threaded fastener pushes the brake assembly 20 forward will decrease. The resetting force of the brake assembly 20 will drive the brake assembly 20 to move away from the wheel hub, thereby causing the brake assembly 20 to move away from the wheel hub. Thus, the gap between the brake assembly 20 and the wheel hub can be adjusted. When the brake pads 23 wear out due to long-term friction, resulting in excessive clearance, the user only needs to tighten the threaded fasteners to move the brake assembly 20 closer to the wheel hub, thus restoring normal braking force. Conversely, when the brake pads 23 are too tightly fitted, causing excessive friction, the threaded fasteners can be loosened appropriately to move the brake assembly 20 away from the wheel hub, achieving the ideal braking clearance. Therefore, this device can be flexibly adjusted according to different usage conditions, avoiding the inconvenience of requiring overall adjustment or parts replacement in traditional braking devices. In this application, the threaded fasteners are bolts or screws, or other threaded fasteners with external threads.

[0021] To ensure stable installation of the braking device in different locations or on different devices, the mounting base 10 of this application has a mounting hole 50 in its center. In this embodiment, the mounting hole 50 is located through the center of the mounting base 10, and its diameter can be designed to match the usage environment and the specifications of the mounting bolts. Through the mounting hole 50, the user can fix the mounting base 10 to the vehicle frame, support rod, or other fixed structure, thereby ensuring the positioning accuracy and installation stability of the entire braking device. During actual installation, standard parts such as fastening bolts, rivets, or pins can be inserted into the mounting hole 50 to form a reliable mechanical connection between the braking device and the mounting base. When the vehicle or equipment is subjected to vibration or impact during operation, the structure of the mounting hole 50 and the fasteners can effectively prevent the braking device from shifting or loosening, thereby maintaining the stability of braking performance. It should be noted that, in order to improve installation stability, each of the four ends of the mounting base 10 is provided with a threaded hole. Through these four threaded holes, multi-point fastening can be used during installation, so that the mounting base 10 forms a more solid support and uniform force distribution on the mounting surface.

[0022] Preferably, the mounting base 10 has a triangular protrusion 60 protruding upward on the side near the brake assembly 20, and the side of the triangular protrusion 60 near the brake assembly 20 is parallel to the brake assembly 20. This triangular protrusion 60 can act as abutment against the brake assembly 20 when the threaded fastener is completely loosened.

[0023] Preferably, the adjusting seat 30 includes a columnar body 31, a connecting column 32, and a pair of connecting plates 33. The columnar body 31 has a through hole 40 for installing threaded fasteners to adjust the brake assembly 20. The bottom of the columnar body 31 is connected to the connecting column 32, and the bottom of the connecting column 32 is fixed to the mounting seat 10, thereby forming an integrated structure of the adjusting seat 30, the mounting seat 10, and the brake assembly 20, ensuring the stability and reliability of force transmission of the entire braking device during use. The two connecting plates 33 are symmetrically arranged on both sides of the columnar body 31 and connected to the columnar body 31, the connecting column 32, and the mounting seat 10 respectively, providing enhanced support and preventing tilting. When the brake assembly 20 is under force, the symmetrical connecting plate 33 structure can disperse and bear the reverse force from the threaded fasteners pushing the brake assembly 20, while preventing the columnar body 31 from twisting or shifting when rotating or subjected to impact, thus improving the overall rigidity and stability of the adjusting seat 30. Through the combination of the columnar body 31, connecting column 32, mounting base 10, and connecting plate 33, the adjusting seat 30 not only ensures the precise connection between the threaded fastener and the brake assembly 20, but also effectively withstands the reaction force of the brake assembly 20 during braking, making the adjustment action smooth and reliable. Simultaneously, the symmetrical arrangement of the connecting plate 33 restricts the axial and lateral sway of the columnar body 31, ensuring the fine-tuning accuracy of the adjusting seat 30 and the brake assembly 20, and improving the repeatability and operational safety of brake clearance adjustment. Preferably, the dimensions of the columnar body 31, the height of the connecting column 32, and the thickness of the connecting plate 33 can be matched and designed according to the specifications, installation position, and operating environment of the brake assembly 20, so that the entire adjusting seat 30, while ensuring structural stability, does not add extra volume and weight, making it suitable for braking device applications on various vehicles or mechanical equipment.

[0024] Furthermore, the columnar body 31 has a chamfered bevel 70 on the side near the brake assembly 20, and the chamfered surface of the columnar body 31 after the chamfered bevel 70 is parallel to the brake assembly 20. By setting the chamfer 70, the brake assembly 20 and the mounting base 10 are set at an acute angle, reducing spatial interference to the brake assembly 20.

[0025] Preferably, the anti-slip component 21 comprises multiple triangular anti-slip protrusions arranged in two rows and multiple columns. By providing these triangular anti-slip protrusions, friction is increased when the brake pads 23 contact the wheel hub, thereby improving grip and stability during braking. Simultaneously, the multi-row, multi-column arrangement ensures uniform force distribution on the brake pads 23, preventing excessively rapid wear on local contact surfaces or uneven braking force. During braking, these anti-slip protrusions not only effectively prevent the brake pads 23 from slipping but also enhance braking reliability under conditions of slight vibration or slippery conditions, improving the overall safety of the vehicle or equipment.

[0026] Preferably, the first angle is 30-150 degrees and the second angle is 60-120 degrees. More preferably, the first angle is 45 degrees and the second angle is 90 degrees, meaning the angle between the brake assembly 20 and the mounting base 10 is 45 degrees, and the adjusting seat 30 is perpendicular to the mounting base 10. This angle design allows the brake assembly 20 to contact the wheel hub at a reasonable tilt angle during braking, thereby generating stable and sufficient friction during braking and achieving efficient braking. Simultaneously, the perpendicularity of the adjusting seat 30 to the mounting base 10 not only facilitates fine-tuning of the threaded fasteners along the axial direction for precise adjustment of the brake clearance but also effectively withstands the reaction force generated during braking, preventing the brake assembly 20 from shifting or deforming. This angle combination design, while ensuring stable transmission of braking force, optimizes the force relationship between the brake assembly 20, the mounting base 10, and the adjusting seat 30, making the entire braking device structure more compact and coordinated. Combination Figure 6 Preferably, the brake assembly 20 includes a mounting base 22 rotatably connected to the adjusting seat 30 and a brake pad 23 disposed on the mounting base 22. An anti-slip member 21 is provided on the side of the brake pad 23 away from the mounting base 22. The connection between the mounting base 22 and the mounting seat 10 is rotatable, allowing the included angle of the brake assembly 20 relative to the mounting seat 10 to change. In this embodiment, a first snap-fit ​​plate 24 is vertically disposed on each of the two sides along the length direction and one side along the width direction of the mounting base 22. A second snap-fit ​​plate 25 is vertically connected to the top of the first snap-fit ​​plate 24. The mounting base 22, the first snap-fit ​​plate 24, and the second snap-fit ​​plate 25 cooperate to form an insertion part for inserting the brake pad 23. Both sides of the brake pad 23 are inserted into the insertion part, achieving a detachable connection of the brake pad 23. The end without the insertion part has a threaded hole, and the brake pad 23 has an insertion hole. When the brake pad 23 is inserted into the mounting base 22 from the side without the insertion part, three ends of the brake pad 23 are held in place by the insertion part, while the insertion hole at the other end aligns with the threaded hole. A bolt is then inserted into the insertion hole and tightened, thus installing the brake pad 23. When the brake pad 23 wears out, the user simply loosens the bolt to disengage it from the locking fit between the threaded hole and the insertion hole, and then pulls the brake pad 23 out of the insertion part along the side without the insertion part, easily completing the disassembly and replacement operation. The entire process does not require disassembly of the mounting base 22 or the adjusting seat 30, nor does it require complex professional tools, greatly improving the flexibility and convenience of maintenance.

[0027] The brake assembly 20 described in this application is an overall arc-shaped brake assembly 20. A contact portion 26 protrudes from the side of the brake assembly 20 facing the through hole 40, and the threaded fastener abuts against this contact portion 26. In this embodiment, the brake assembly 20 has an overall arc-shaped structure design, and its curvature matches the outer arc surface of the wheel hub. When the braking device is in operation, the brake assembly 20 can uniformly conform to the outer surface of the wheel hub with a large area, generating braking force through friction, thereby achieving effective deceleration or braking of the wheel. The arc-shaped structure design not only increases the contact area between the brake assembly 20 and the wheel hub, but also disperses the force during braking, avoiding localized stress concentration, thereby effectively reducing uneven wear of the brake pads 23 and extending their service life.

[0028] This utility model provides an easily adjustable braking device, comprising a braking device body 1 and a threaded fastener. An adjusting seat 30 is provided on the braking device body 1, and a threaded fastener is installed in the through hole 40 of the adjusting seat 30, allowing one end of the threaded fastener to abut against the braking assembly 20. By rotating the threaded fastener, it can be moved axially. When the threaded fastener moves axially along the through hole 40, its front end abuts against the abutment portion 26 of the braking assembly 20, thereby causing the braking assembly 20 to make a slight displacement along the line connecting the mounting seat 10 and the wheel hub. Specifically, tightening the threaded fastener pushes the braking assembly 20 closer to the wheel hub, while loosening the threaded fastener moves the braking assembly 20 away from the wheel hub, thus adjusting the distance between the braking assembly 20 and the wheel hub. When the brake assembly 20 wears down due to prolonged use, the user does not need to disassemble the entire brake structure; simply rotating the threaded fasteners is sufficient to quickly compensate for the brake clearance, allowing the brake pads 23 to regain a proper distance from the wheel hub. This greatly improves the adjustment efficiency and maintenance convenience of the device. Therefore, compared with traditional fixed brake structures, the adjustable brake device of this application offers more flexible adjustment methods, enabling rapid fine-tuning of the brake device and effectively ensuring the stability of the brake clearance and the reliability of braking performance.

[0029] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
