Description

Technical Field

[0001] This utility model belongs to the field of brake wheel technology, specifically relating to an invisible brake wheel. Background Technology

[0002] With social progress and improved living standards, home furnishing products have received much attention. Nowadays, many pieces of furniture, such as bedside tables, chairs, and filing cabinets, are usually equipped with small brake wheels at the bottom to reduce the time and effort required for manual handling.

[0003] Existing furniture brake wheels typically employ a brake assembly to achieve braking after being moved to a designated position. This assembly uses a transmission component, a toggle component, and a semi-locking component in a coordinated manner. When not in use, one of the locking blocks of the semi-locking component engages with the rotating wheel below it, thus locking the rotating wheel. However, because the brake wheel requires the simultaneous adjustment of multiple control components during braking, the excessive number of parts increases the failure rate of the brake wheel, making repairs more difficult and resulting in higher maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide an invisible brake wheel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an invisible brake wheel, comprising:

[0006] The bracket has a base connected to its bottom via a limiting member, and the bottom of the base is rotatably connected to a roller;

[0007] The brake cover has a brake support at its bottom. One end of the brake support passes through the bracket and the base and is inserted into the V-shaped brake groove inside the roller to stop the roller from rotating.

[0008] Preferably, the top of the bracket is connected in a ring with several locking rings and slots are provided between the locking rings, the bottom of the brake cover is connected with two sets of inclined blocks, and the brake support is provided with inclined grooves on both sides.

[0009] Preferably, a plurality of locking blocks are connected in a ring at the bottom of the brake cover, and when the locking blocks are screwed into the locking ring, the inclined blocks are inserted into the inclined grooves.

[0010] Preferably, the slot has limiting grooves on both sides, and the brake support is connected to limiting blocks on both sides. When one end of the brake support is inserted into the slot, the limiting blocks slide into the limiting grooves.

[0011] Preferably, the limiting component includes a pin, and the pin is provided in several groups and the several groups of pins are connected in a ring inside the bottom of the bracket, and a locking block is connected to the pin.

[0012] Preferably, after one end of the insert is inserted into the base, the locking block is engaged with the bottom of the base.

[0013] Preferably, the top of the base is provided with a ball groove and a plurality of balls are provided in the ball groove.

[0014] Preferably, the bottom of the base is connected to two sets of rotating frames and the roller is rotatably connected between the two sets of rotating frames through a rotating shaft. The brake groove is provided in several sets and the several sets of brake grooves are arranged in a ring inside the roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Braking is achieved by the cooperation of the brake cover and the brake support with the brake groove inside the roller. Only by operating the brake cover can the brake support be inserted into the brake groove, thereby quickly rotating the roller. This greatly simplifies the braking process, reduces the difficulty of operation, and reduces the number of fault points caused by the complex linkage of parts. The fewer parts make it easier to troubleshoot, thereby greatly reducing the difficulty of maintenance and improving maintenance efficiency.

[0017] (2) The bottom of the bracket is connected to the base through a limiting component. The insert and the locking block in the limiting component ensure a stable connection between the base and the bracket. The ball in the ball groove at the top of the base makes the relative rotation between the base and the bracket smoother and more stable, allowing the bracket and the base to rotate flexibly 360° through the ball.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] This utility model provides, for example Figure 1-4 The concealed brake wheel shown includes:

[0026] A bracket 1, the bottom of which is connected to a base 2 via a limiting member, and a roller 3 is rotatably connected to the bottom of the base 2;

[0027] Brake cover 4, with brake support 5 at the bottom. One end of brake support 5 passes through bracket 1 and base 2 and is inserted into brake groove 6 in V-shape inside roller 3 so that roller 3 stops rotating.

[0028] The top of the bracket 1 is connected in a ring with several locking rings 7 and slots 8 are provided between the locking rings 7. The bottom of the brake cover 4 is connected with two sets of inclined blocks 18. The brake support 5 is provided with inclined grooves 17 on both sides.

[0029] The bottom of the brake cover 4 is connected in a ring with several locking blocks 9. When the locking blocks 9 are screwed into the locking ring 7, the inclined block 18 is inserted into the inclined groove 17.

[0030] The slot 8 has limiting grooves 10 on both sides, and the brake support 5 is connected to limiting blocks 11 on both sides. When one end of the brake support 5 is inserted into the slot 8, the limiting block 11 slides into the limiting groove 10. The limiting block 11 is stuck in the limiting groove 10 and cooperates with the square slot 8, which can effectively prevent the brake support 5 from moving laterally in the slot 8.

[0031] The limiting component includes a pin 12, which has several sets connected in a ring at the bottom of the bracket 1. A locking block 13 is connected to the pin 12. After one end of the pin 12 is inserted into the base 2, the locking block 13 is engaged with the bottom of the base 2. The pin 12 is inserted into the base 2 and is engaged by sliding the locking block 13. The main function of the pin 12 is to provide axial positioning, ensure that the base 2 and the bracket 1 are stably connected in the vertical direction, and prevent the base 2 from falling off the bracket 1. This forms a reliable connection structure, ensuring that the base 2 and the bracket 1 will not separate. This connection method does not restrict the relative rotation of the base 2 and the bracket 1, so that the two can easily rotate 360° around the axis of the pin 12.

[0032] The base 2 has a ball groove 14 at the top and a plurality of balls 15 in the ball groove 14.

[0033] The base 2 has two sets of rotating frames 16 connected to its bottom, and the roller 3 is rotatably connected between the two sets of rotating frames 16 via a rotating shaft. The brake groove 6 has several sets, and the several sets of brake grooves 6 are arranged in a ring inside the roller 3. The ring-shaped distribution of the brake grooves 6 ensures that no matter what rotation angle the roller 3 is at, the brake support 5 can be inserted into the brake groove 6 to brake, avoiding braking failure due to the angle of the roller 3, and significantly improving the success rate and reliability of braking.

[0034] The concealed brake wheel securely fixes the bracket 1 to the bottom of the furniture via pre-drilled mounting holes. When the concealed brake wheel is in motion, the brake cover 4 is not screwed into the top of the bracket 1, and the brake support 5 is in a free-moving state. The limiting blocks 11 on both sides of the top of the brake support 5 are slidably connected to the limiting grooves 10 on both sides of the top slot 8 of the bracket 1, ensuring that the brake support 5 can only move in a specific direction. The bottom side of the brake support 5 is inserted into the V-shaped brake groove 6 inside the roller 3, but does not brake the roller 3. At this time, when an external force pushes the furniture with the brake wheel installed, the roller... As the roller 3 begins to rotate, due to the V-shaped structure of the brake groove 6 of the roller 3, the side wall of the brake groove 6 will generate an upward component force on the bottom of the brake support 5 during the rotation of the roller 3, causing the brake support 5 to slide upward along the limiting groove 10. As the brake support 5 gradually slides out of the brake groove 6, the two disengage, and the roller 3 is no longer obstructed by the brake support 5, and can rotate freely and smoothly. At the same time, the ball bearings 15 in the ball bearing groove 14 at the top of the base 2 enable the base 2 and the bracket 1 to achieve 360° flexible relative rotation. Combined with the rolling of the roller 3, the furniture can move freely on the plane.

[0035] When the furniture needs to be fixed in a designated position after being moved, take out the brake cover 4 and screw the brake cover 4 into the locking ring 7 at the top of the bracket 1. Several locking blocks 9 arranged in a ring at the bottom of the brake cover 4 cooperate with the locking ring 7. During the screwing process, the inclined block 18 at the bottom of the brake cover 4 is inserted into the inclined groove 17 on both sides of the brake support 5, further restricting the movement space of the brake support 5. As the brake cover 4 is tightened, the brake cover 4 applies downward pressure to the top of the brake support 5, forcing the bottom of the brake support 5 to be firmly inserted into the brake groove 6 of the roller 3. Since the brake groove 6 is V-shaped, after the brake support 5 is inserted, the side wall of the brake groove 6 will exert an inward squeezing force on the brake support 5, forming a strong friction force, which will tightly lock the brake support 5 and prevent it from moving. At this time, the brake support 5 restricts the rotation of the roller 3, thereby achieving braking of the roller 3 and keeping the furniture stably in the current position.

[0036] To release the brake and restore the furniture's mobility, simply rotate the brake cover 4 counterclockwise. The locking block 9 at the bottom of the brake cover 4 gradually separates from the locking ring 7 at the top of the bracket 1, and the pressure of the brake cover 4 on the brake support 5 disappears. After the pressure is released, when the furniture is pushed again to rotate the roller 3, the V-shaped sidewall of the brake groove 6 of the roller 3 will again exert an upward force on the bottom of the brake support 5, causing the brake support 5 to slide upward along the limit groove 10 and exit from the brake groove 6. As the brake support 5 disengages from the brake groove 6, the roller 3 returns to a free-rotating state, and the ball bearing 15 between the base 2 and the bracket 1 continues to function, allowing the furniture to move freely again. This braking process greatly reduces potential points of failure and improves ease of use and reliability.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
