Description

Technical Field

[0001] The utility model relates to the technical field of the specific structure of a braking system, in particular to a detachable braking system. Background Art

[0002] In the prior art, large braking systems are integrally formed and are directly assembled into devices such as vehicles for use. During maintenance or other processes, it is not easy to remove them. The integrated structure makes the connection between the brake pads and the upper drive and brake cables, etc., very tight and difficult to disassemble. The main defects are as follows:

[0003] 1) Difficult maintenance: If the casters or the braking system are damaged, the inability to disassemble will make maintenance difficult. It may be necessary to replace the entire device product with casters or perform complex maintenance operations.

[0004] 2) Inconvenient cleaning: The wheels and the braking system are prone to accumulating dust and dirt. The inability to disassemble will make cleaning difficult, thus affecting the smooth rotation of the wheels and the effectiveness of the brakes.

[0005] 3) High replacement cost: If the casters are damaged and cannot be disassembled, the user may need to replace the entire luggage instead of just replacing the wheels, which will increase the maintenance and replacement costs.

[0006] 4) Poor flexibility: Non-detachable casters limit the possibility of replacing different types of wheels. For example, users may need to replace the wheels suitable for different ground surfaces according to different usage scenarios, but fixed casters cannot meet this requirement.

[0007] 5) Limited service life: The non-detachable structural design restricts the use of the casters with the braking system. Once a problem occurs, the entire structure needs to be replaced, resulting in a short service life. Summary of the Utility Model

[0008] The purpose of the utility model is to provide a detachable braking system. By using a quick-release cavity, while completing the disassembly of the quick-release cavity, the rotating shaft is exposed, and then the transmission mechanism, etc., can be disassembled subsequently.

[0013] Further, a slideway is formed locally in the quick-release cavity, the sliding mechanism is a slider moving along the slideway, the slider is connected with a sheet metal part, and the brake shaft is arranged through the sheet metal part.

[0014] Further, a locking cavity and an unlocking cavity that communicate with each other are provided on the sheet metal part, the locking cavity and the unlocking cavity constitute the hanging groove, and the slider is arranged close to the unlocking cavity.

[0015] Further, a locking groove matching the locking cavity is formed by local depression of the universal rotating shaft. During the movement of the slider, the locking groove is driven to reciprocate between the locking cavity and the unlocking cavity.

[0016] Further, the hanging groove matching the locking cavity is formed by local depression of the universal rotating shaft. During the movement of the slider, the hanging groove is driven to reciprocate between the locking cavity and the unlocking cavity.

[0017] Further, a base is also included, the quick-release cavity is located on the base, the base forms a protective cavity close to the sheet metal part along the outer periphery of the quick-release cavity, and a reduced-diameter cavity with a gradually decreasing gap from top to bottom is formed between the protective cavity and the quick-release cavity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The present utility model will be described in detail below in conjunction with the embodiments shown in the drawings. However, it should be noted that these embodiments are not intended to limit the present utility model. Any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present utility model.

[0034] Refer to the attached Figures 1-5 As shown, in this embodiment, the detachable brake system specifically includes a brake assembly 100 and a quick-release cavity 200. A universal rotating shaft 220 is sleeved outside the core brake shaft 110 in the brake assembly 100, and the universal rotating shaft 220 is associated with the quick-release in the quick-release cavity 200. Thus, during the disassembly of the quick-release cavity 200, the free movement or restricted movement of the brake shaft 110 can be controlled (at this time, mainly the universal rotating shaft 220 is stuck, resulting in the brake shaft 110 inside it not being able to be exposed, causing restricted movement), and thus the disassembly and assembly are completed during this process.

[0035] Specifically, the brake assembly 100 further includes a first transmission mechanism 130 equipped with a brake wire 120, and a second transmission mechanism 140 connected to the first transmission mechanism 130 through the brake shaft 110. The second transmission mechanism 140 includes a brake stop piece 141. During the braking action, the brake wire 120 is controlled to drive the first transmission mechanism 130, link the brake shaft 110, and act on the brake stop piece 141 to clamp the roller 1, thereby completing the relative braking process. Under normal conditions, the brake wire 120 does not move, and the first transmission mechanism 130, the brake shaft 110, and the brake stop piece 141 in the second transmission mechanism are all in a normal connection state but not under force.

[0036] For the quick-release cavity 200, the quick-release cavity 200 includes a sliding mechanism 210. The sliding mechanism 210 is connected to a force application component 220, and the other end of the sliding mechanism 210 is connected to a universal rotating shaft 220 for the brake shaft 110 to pass through. A hanging groove 230 for hanging the universal rotating shaft 220 is provided on the quick-release cavity.

[0037] During the specific disassembly, a slideway 240 is formed locally in the quick-release cavity 200. The sliding mechanism 210 is a slider moving along the slideway. The slider is connected to a sheet metal part 250, and the brake shaft 110 passes through the sheet metal part 250. During this process, the slider can be directly welded to the sheet metal part 250, and then the slider slides along the slideway 240, causing the sheet metal part 250 to move left and right synchronously.

[0038] In this embodiment, in order to cooperate with the locking and unlocking of the universal rotating shaft 220 to drive the restriction of the movement of the brake shaft, at this time, a locking cavity 251 and an unlocking cavity 252 that communicate with each other are provided on the sheet metal part 250. The locking cavity 251 and the unlocking cavity 252 constitute the hanging groove 230, and the slider is arranged close to the unlocking cavity 251. During the movement of the slider, the hanging groove 230 formed by the locking cavity and the unlocking cavity is driven to move horizontally, so that the universal rotating shaft is locked or unlocked.

[0039] In the actual design, both the locking cavity and the unlocking cavity are circular holes with different aperture sizes. At this time, the diameter of the universal rotating shaft 220 is larger than that of the locking cavity, so a local depression is formed on it to form a locking groove 221 that matches the locking cavity 251. During the movement of the slider, the locking groove 221 is driven to enter the unlocking cavity 252 with a larger diameter for free movement. At this time, the universal rotating shaft 220 can be directly disassembled, and then the brake shaft 110 can also be disassembled, so that the connection between the upper and lower first transmission mechanisms 130 and second transmission mechanisms 140 is disconnected, and the entire braking system is disassembled; or the locking groove 221 enters the smaller locking cavity 251 and is stuck, so that the universal rotating shaft 220 cannot move. At this time, the brake shaft 110 located inside it will also be restricted, and the assembly is completed. During the above process, the locking groove 221 specifically reciprocates between the locking cavity and the unlocking cavity.

[0040] In this embodiment, a slideway 240 is directly formed on the outer periphery of the slider in the quick-release cavity 200. To protect the entire sliding, a base 300 is further included. The base 300 forms a protective cavity 310 close to the sheet metal part 250 along the outer periphery of the quick-release cavity 200. A reduced-diameter cavity 320 with a gradually decreasing gap from top to bottom is formed between the protective cavity 310 and the quick-release cavity 200. The protective cavity 310 can protect the movement of the sheet metal part 250 and the slider. At the same time, the setting of the reduced-diameter cavity makes it possible that once the slider fails and continues to move, it will first contact the smallest bottom of the reduced-diameter cavity, and then move forward (i.e., towards the protective cavity) under the action of inertia and contact the wider upper part. This not only releases the inertia but also stops moving after contacting the upper part, providing good protection in case of brake failure.

[0041] In this embodiment, the slideway is formed at the bottom of the base 300, and the sheet metal part is arranged above the slideway, which can not only move along the slideway but also be supported, making it have greater strength.

[0042] In order to achieve subsequent reset, a reset spring 260 is provided between the slider and the sheet metal part 250. On the side of the slider away from the reset spring 260, a guiding inclined surface 211 that acts with the quick-release button 270 is formed. At this time, the quick-release button can be arranged below the base 300. Press the quick-release button 270, which pushes the slider to drive the sheet metal part 250 to move towards the direction close to the brake shaft to complete locking; press the quick-release button again, touch the reset spring, and it resets, driving the slider to move in the reverse direction to complete unlocking and disassembly.

[0043] Regarding the specific transmission mechanism, the introduction is as follows:

[0044] First, the first transmission mechanism 130 includes a rotating rod 132 connected to the brake line 120 and having a first brake torsion spring 131, and the rotating rod 132 is rotatably connected to the brake connecting member 133. At this time, the brake connecting member 133 is tilted downward, and the brake shaft 110 extends out of the quick release cavity 200 and abuts against the brake connecting member 133.

[0045] Secondly, in use, when the brake line 120 is forced to move upward, the rotating rod 132 is forced to move upward, and the torsion spring drives the torsion force. The brake connecting piece 133 arranged downwardly and tilted is driven to rotate and move downward by the rotating rod 132, so that the brake shaft 110 is pressed. At this time, the connecting rod passing through the universal rotating shaft 220 and the brake shaft 110 is connected to the two sides of the cavity formed by the brake stop plate 141 at both ends and is located in the cavity, and then it drives the brake stop plate 141 in the second transmission mechanism 140 to move downward at one end, and the other end connected to the roller 400 moves upward under the action of the lever, driving the brake stop plate 141 to trigger the second brake torsion spring 142 assembled therewith to twist, and at the same time, the brake stop plate 141 is clamped into the clamping groove of the roller 400, and the braking is completed at this time;

[0046] As for the brake stopper, a rotation cavity is formed on both sides of the roller and rotates along the roller, and the second brake spring 142 is coaxially mounted in the rotation cavity.

[0047] For better assembly, a fixing seat 500 is also included, which is located outside the roller 400. The brake stopper 141 and the second brake torsion spring 142 are located in the assembly cavity formed by the fixing seat 500, and the two ends of the second brake torsion spring 142 are respectively fixed to the assembly cavity and the brake pad 141. At this time, the fixing seat can be set below the base and connected thereto. In this embodiment, the fixing seat 500 is located below the base 300, but the two are not connected, but the structural settings are matched. The fixing seat 500 is mainly connected to the central axis of the roller 400. A large cylindrical cavity is set above the fixing seat 500 to form a protection for the universal shaft 220 during the lifting and lowering, and the bottom of the base 300 is recessed to form a clearance cavity matching the cylindrical cavity, so that the two seem to match, but are actually not fixedly connected.

[0048] In the utility model, the brake assembly is divided into two parts, the upper part is connected to the first transmission mechanism and the quick-release chamber 200, and then the lower part is independently integrated with the universal shaft. At the same time, the quick-release chamber 200 forms a local protection chamber during the braking action. In the quick-release chamber 200, when the universal shaft 220 is completely disassembled, the brake shaft 110 is abutted against the first transmission mechanism 130. At this time, the shaft 220 can be used to keep it away from the first transmission mechanism and the quick-release chamber, so that the brake assembly is divided into an upper half and a lower half to complete its disassembly.

[0049] Again, after the braking ends, the force on the brake cable 120 disappears and it moves downward. Then, under the action of the first brake torsion spring and the like, the rotating rod moves downward, the brake connecting member 133 rotates around the rotation point, and then the brake shaft 110 moves upward, driving the brake stop piece 141 to reset and the braking force disappears.

[0050] In the present utility model, through the setting of the quick-release cavity, the disassembly efficiency of the whole is improved, overcoming the problem in the prior art that the structure in the braking system is not easy to disassemble. Especially after being assembled with rollers and the like, the braking system and the brake cable form an integral whole and are disassembled and assembled as a whole. Although the overall assembly is convenient, the maintenance cost is relatively high. In this embodiment, however, by controlling the quick-release button 270, good disassembly and installation can be achieved for easy maintenance.

[0051] The series of detailed descriptions listed above are only specific descriptions of the feasible implementation manners of the present utility model, and they are not intended to limit the protection scope of the present utility model. Any equivalent implementation manners or changes made without departing from the technical spirit of the present utility model should be included in the protection scope of the present utility model.

[0052] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.

[0053] In addition, it should be understood that although this specification is described according to the implementation manners, not every implementation manner only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
