Description

Technical Field

[0001] This utility model relates to the field of roller structure technology, and more specifically to a bracket roller that is easy to install. Background Technology

[0002] As common structural components, bracket rollers are widely used in the housings of electrical appliances, furniture, sliding doors, logistics and transportation devices, and the housings or support parts of various mechanical equipment. Their function is to achieve smooth movement or guiding positioning of equipment components through the rollers. Existing bracket rollers typically use screws, pins, or press-fit structures to fix the rollers to the support shaft, which has several shortcomings. For example, installation is complex; existing bracket rollers often require additional fasteners or special tools during assembly, making the assembly process cumbersome and unsuitable for mass production and rapid maintenance. Furthermore, in some structures, fasteners protrude from the outer surface of the support shaft, easily interfering with the inner hole of the roller, leading to poor rolling and affecting service life. Additionally, in traditional structures, if screws loosen or pins wear, the roller may fall off, posing a safety hazard. Therefore, there is still a need for a bracket roller with a simpler structure, easier installation, and the ability to ensure free rotation of the roller without easily detaching it, to solve the above problems. Utility Model Content

[0003] In view of this, the present invention provides a bracket roller that is easy to install.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An easy-to-install bracket roller, comprising:

[0006] The bracket has a support shaft;

[0007] The roller has a shaft hole that matches the support shaft, and the roller is sleeved on the support shaft through the shaft hole;

[0008] The buckle includes: a limiting cap and at least two claws disposed on the limiting cap; the claws extend away from the limiting cap; the outer diameter of the limiting cap is larger than the diameter of the shaft hole; the support shaft has a groove from top to bottom, and a locking block is disposed in the groove near the top of the support shaft;

[0009] The opening of the claw is provided with a limiting protrusion;

[0010] The buckle is assembled with the support shaft buckle, the claw is inserted into the groove, and the limiting protrusion of the claw abuts against the block in the axial direction; the roller is restricted and sleeved on the support shaft by the limiting cap.

[0011] As a preferred embodiment of this utility model, the number of the claws is two, and they are arranged symmetrically; the limiting protrusions are provided on the opposing sides of the claws.

[0012] As a preferred embodiment of this utility model, the number of the claws is three, and the three claws are evenly distributed on the same circumference. The limiting protrusion is provided on the side of the claw facing the center of the circle.

[0013] As a preferred embodiment of this utility model, a limiting hole is formed between the bottom of the card block and the inner bottom surface of the groove; when the buckle is assembled with the support shaft buckle, the limiting protrusion is at least partially located within the limiting hole.

[0014] In a preferred embodiment of this utility model, the top of the card block is provided with a guide slope; the guide slope guides the card claw to insert into the groove.

[0015] In a preferred embodiment of this utility model, the groove extends through the circumferential surface of the support shaft; after the buckle is assembled with the support shaft buckle, the claw is located inside the groove or the outer surface of the claw is on the same circumferential surface as the circumferential surface of the support shaft.

[0016] As a preferred embodiment of this utility model, a mounting groove is provided on the upper surface of the roller, and the mounting groove is coaxially distributed with the shaft hole; the limiting cap is located in the mounting groove.

[0017] In a preferred embodiment of this utility model, the limiting cap is arranged in a disc shape; the mounting groove is arranged in a ring shape.

[0018] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0034] like Figures 1-6 As shown, this embodiment proposes a bracket roller that is easy to install, including a bracket 1, a roller 2, and a buckle 3. The roller 2 is assembled on the bracket 1, and the buckle 3 is combined with the bracket 1 to prevent the roller 2 from separating from the bracket 1.

[0035] The bracket 1 is used to fix the device housing or other mounting base, and can be made of metal or engineering plastic. The bracket 1 has a support shaft 11; specifically, the bracket 1 can be... Figure 1 The support includes a rod-shaped base 15 and a support shaft 11 disposed on the base 15. The support shaft 11 is preferably integrally formed with the base to reduce assembly steps, while the overall structure of the support 1 is more stable.

[0036] Alternatively, the base 15 can be in other shapes.

[0037] The support shaft 11 is preferably cylindrical, with the end of the support shaft 11 connected to the base 15 being the bottom and the end of the support shaft 11 away from the base 15 being the top.

[0038] The roller 2 is provided with a shaft hole 21 that matches the support shaft 11, and the roller 2 is sleeved on the support shaft 11 through the shaft hole 21; the roller 2 can be made of engineering plastic, such as PPS or SPS, to improve wear resistance and high temperature resistance.

[0039] The latch 3 includes a limiting cap 31 and at least two claws 32 disposed on the limiting cap 31; the claws 32 extend away from the limiting cap 31; the outer diameter of the limiting cap 31 is larger than the diameter of the shaft hole 21. After the latch 3 and the bracket 1 are assembled, they can prevent the roller 2 from disengaging from the top of the support shaft 11. The limiting cap 31 and the claws 32 can be made of metal or engineering plastic. The claws 32 preferably have a certain degree of elasticity to ensure that they can open smoothly during installation and reliably engage after resetting.

[0040] The support shaft 11 has a groove 12 from top to bottom. A locking block 13 is provided in the groove 12 near the top of the support shaft 11. A limiting protrusion 322 is provided at the beginning of the locking claw 32.

[0041] like Figure 6As shown, the buckle 3 is snapped together with the support shaft 11, the claw 32 is inserted into the groove 12, and the limiting protrusion 322 of the claw 32 abuts against the block 13 in the axial direction (i.e., Figure 6 In the vertical direction, the roller 2 is restricted by the limiting cap 31 and sleeved on the support shaft 11. The roller 2 cannot be disengaged from the support shaft 11. At the same time, the buckle 3 cannot be pulled out upward because the limiting protrusion 322 and the buckle block 13 are abutted in the axial direction. The overall assembly is stable and the installation method is simple.

[0042] In one implementation, such as Figure 4 As shown, there are two claws 32, which are arranged symmetrically; the opposing sides of the claws 32 are provided with limiting protrusions 322;

[0043] Here, the end where the claw 32 is connected to the limit cap 31 is defined as the end, and the end away from the limit cap 31 is defined as the beginning.

[0044] like Figure 6 As shown, before the two claws 32 are installed on the bracket 1 and under no external force, the distance between the limiting protrusions 322 of the two claws 32 should be less than the thickness of the locking block 13. Therefore, during the installation of the buckle 3 and the bracket 1, the claws 32 are pushed into the groove 12, and the reverse thrust of the locking block 13 acts on the limiting protrusions 322, which causes the two claws 32 to open relative to each other, and the claws 32 undergo slight deformation. After the buckle 3 is inserted, the limiting protrusions 322 leave the locking block 13, and the claws 32 return to their original position. Figure 6 As shown, at this time, the limiting protrusion 322 is located at the bottom of the locking block 13 and abuts against the locking block 13 axially, effectively preventing the buckle 3 from being pulled upward.

[0045] In one embodiment, a limiting hole 14 is formed between the bottom of the latch 13 and the inner bottom surface of the groove 12; when the latch 3 and the support shaft 11 are snapped together, the limiting protrusion 322 is at least partially located in the limiting hole 14; the limiting hole 14 is mainly for accommodating the limiting protrusion 322.

[0046] In one embodiment, the top of the locking block 13 is provided with a guide slope 131; the guide slope 131 guides the locking claw 32 to be inserted into the groove 12. As described above, during the installation of the buckle 3 and the bracket 1, the locking claw 32 is pushed into the groove 12, and the reverse thrust of the locking block 13 acts on the limiting protrusion 322. The guide slope 131 is provided to facilitate the relative opening of the two locking claws 32.

[0047] Optionally, the number of jaws 32 can be changed according to actual needs, and the shape of the groove 12 can be modified accordingly to accommodate multiple jaws 32. For example, if there are three jaws 32, the three jaws 32 are evenly distributed on the same circumference, and a limiting protrusion 322 is provided on the side of the jaw 32 facing the center. The three jaws 32 are spaced approximately 120° apart from each other, and the positions of the groove 12, the locking block 13, and the guide slope 131 of the support shaft 11 can be adjusted accordingly so that the three jaws can be evenly engaged. The installation method of the three-jaw scheme is basically the same as that of the two-jaw scheme described above. The difference is that the three-jaw scheme can provide stronger engagement stability and load-bearing capacity, and is suitable for larger-sized or heavy-load rollers.

[0048] In one embodiment, the groove 12 extends through the circumferential side of the support shaft 11. After the buckle 3 is snapped together with the support shaft 11, the claw 32 is located inside the groove 12 and does not protrude from the groove 12, which can ensure that the roller 2 can rotate smoothly around the support shaft 11 during rotation.

[0049] Alternatively, the groove 12 passes through the circumferential side of the support shaft 11. After the buckle 3 is snapped together with the support shaft 11, the outer side of the claw 32 and the circumferential side of the support shaft 11 are on the same circumferential surface, which can also ensure that the roller 2 can rotate smoothly around the support shaft 11 during rotation.

[0050] In one embodiment, a mounting groove 22 is provided on the upper surface of the roller 2, and the mounting groove 22 is coaxially distributed with the shaft hole 21; the limiting cap 31 is located within the mounting groove 22. The limiting cap 31 is disc-shaped; the mounting groove 22 is annular, and this design ensures that the limiting cap 31 does not affect the rotation of the roller 2; Figure 6 As shown, the limiting cap 31 is only partially located within the mounting groove 22. There is a gap between the lower surface of the limiting cap 31 and the inner bottom surface of the mounting groove 22, as well as a gap between the peripheral side surface of the limiting cap 31 and the peripheral side surface of the mounting groove 22. This reduces the friction between the roller 2 and the limiting cap 31, making the roller 2 rotate more smoothly.

[0051] In particular, the bracket roller of this utility model is suitable for use in high-temperature rotating devices for microwave appliances.

[0052] This utility model's bracket roller is not only suitable for installing appliance housings, but can also be widely used in furniture, sliding doors, machinery housings, logistics and transportation devices, etc., demonstrating good versatility and promotional value. Through the above embodiments, the bracket roller of this utility model is easy and quick to install, requiring no complex tools for assembly; the roller can rotate freely, and the limiting cap effectively prevents the roller from dislodging; the outer surface of the claw does not protrude from the outer surface of the support shaft, ensuring smooth rolling; the structure is simple, with few parts and low manufacturing cost; the number of claws can be adjusted according to needs, making it widely applicable; suitable for appliance housings, it can also be applied to furniture, equipment, and other mounting bases.

[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
