Description

Technical Field

[0001] The utility model relates to the technical field of mounting brackets, in particular to a shaft mounting bracket and a mounting structure thereof. Background Art

[0002] In modern industrial production and logistics, conveying equipment plays a vital role. Among them, roller conveyors are widely used due to their high efficiency and stable conveying performance.

[0003] Roller conveyors typically consist of a roller and a mounting shaft. The roller is rotatably connected to the mounting shaft. When an object is conveyed on the roller, the roller rotates, thereby conveying the object. In actual applications, the mounting shafts at both ends of the roller need to be fixedly connected to the equipment frame to ensure the stability and reliability of the entire conveyor system.

[0004] However, currently, when the mounting shaft is fixedly mounted on the equipment frame, an axial hole connected to the mounting shaft is provided on the equipment frame, and a nut is then connected to the mounting shaft for fixed connection. This mounting method has the problem that the roller is inconvenient to disassemble and assemble.

[0005] Therefore, how to conveniently, quickly and stably fix and install the installation shaft and the equipment frame and quickly disassemble it has become a problem that needs to be solved urgently in the current field of roller conveyor devices. Utility Model Content

[0006] In view of the problems pointed out in the background technology, the present invention proposes a shaft mounting bracket and a mounting structure thereof to solve the above technical problems.

[0007] The technical solution of the present utility model is achieved as follows:

[0008] A shaft mounting bracket includes a U-shaped clamping portion and connecting holes passing through both ends of the clamping portion, a bolt is connected in the connecting hole, and a nut is connected to the bolt. A clamping hole is provided on the inner side of the middle portion of the clamping portion, an extension section extends from one end of the clamping portion, and a fixing strip connected to the extension section is further provided, and fixing holes are respectively provided at both ends of the fixing strip.

[0009] The utility model is further configured such that the extension section is arranged perpendicular to the fixing bar.

[0010] The utility model is further configured to further include a deformation groove that passes through the middle of the clamping part.

[0011] The present invention is further configured such that the width of the deformation groove gradually decreases from the middle of the clamping portion to the end of the clamping portion.

[0012] The utility model is further configured such that the cross section of the clamping hole is hexagonal.

[0013] The utility model is further configured such that the extension end is thickened.

[0014] A shaft mounting structure includes two side plates, a roller is provided between the two side plates, and a rotating shaft is provided at both ends of the roller. The side plates are provided with connecting grooves, which pass through the upper side of the side plates. The above-mentioned mounting bracket is arranged on the outer side of the side plates. A through hole corresponding to the fixing hole is provided on the side plates. Fastening screws are connected in the fixing hole and the through hole, and the rotating shaft is connected in the clamping hole.

[0015] The utility model is further configured such that a fastening ring is threadedly connected to the rotating shaft.

[0016] The present invention is further configured such that chamfers are respectively provided on both sides of the upper end of the connecting groove.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] First, the connecting groove on the side panel runs through the upper side, so that the rotating shaft can be easily installed into the connecting groove from above when the drum is installed, and can be moved upward when disassembled. It is convenient and quick, greatly improving the efficiency of installation and disassembly, and reducing the difficulty and time cost of operation.

[0019] Secondly, the shaft mounting bracket is cleverly designed. The U-shaped clamping section uses bolts and nuts to adjust the clamping force, effectively securing the shaft. An extended section at one end of the clamping section, perpendicular to the fixing bar, is thickened, increasing structural strength and ensuring a stable connection to the side panels. Furthermore, a deformation groove running through the center of the clamping section forces the clamping section into the groove when the fastening ring is tightened, tightly pressing the inner wall of the clamping hole against the shaft, further enhancing the reliability of the fixed connection.

[0020] Finally, the hexagonal cross-section of the clamping hole provides a better fit for the shaft, preventing rotation and displacement and improving clamping stability. Chamfered corners on both sides of the upper end of the connecting groove facilitate shaft insertion, reducing installation resistance and collision wear, and protecting the structural integrity of the device. Overall, this patent provides an efficient, stable, and easy-to-maintain solution for shaft installation in roller conveyors. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference as follows Figure 1-7 The utility model is described as follows:

[0032] Example 1: A shaft mounting structure includes two side plates 10, a roller 11 is provided between the two side plates 10, and a rotating shaft 12 is provided at both ends of the roller 11, and the roller 11 and the rotating shaft 12 form a rotatable connection. The two side plates 10 play a key role in supporting and fixing the entire structure. They provide a stable installation base for the roller 11 and related components, ensuring that the entire conveying system remains stable during operation. The roller 11 is the main component for conveying objects, and a rotating shaft 12 is provided at both ends. A rotatable connection is formed between the roller 11 and the rotating shaft 12. This connection method enables the roller 11 to rotate smoothly when conveying objects, reduces friction resistance, and improves conveying efficiency.

[0033] The side panel 10 is provided with a connecting groove 13 extending through the upper side of the side panel 10. The rotating shaft 12 is connected to the connecting groove 13. This provides convenient access for installing and removing the rotating shaft 12. When installing the drum 11, the rotating shaft 12 can be moved downward from the upper side of the connecting groove 13 to fit into the connecting groove 13. This installation method is very convenient, requiring no complicated tools or tedious steps. The operator simply aligns the rotating shaft 12 with the upper side of the connecting groove 13 and gently moves it downward. The rotating shaft 12 is then smoothly installed into the connecting groove 13, completing the installation of the drum 11.

[0034] Removing the roller 11 is also convenient. Simply move the rotating shaft 12 upward and out of the connecting slot 13, and the roller 11 can be easily removed from the side panel 10. This design greatly facilitates equipment maintenance and replacement. If the roller 11 malfunctions or needs to be replaced, the operator can quickly remove it for repair or replacement, and then simply install the new roller 11. This significantly reduces equipment downtime and improves production efficiency.

[0035] Axle mounting brackets are provided on the outer sides of the two side plates 10 to fix the rotating shaft 12 .

[0036] The shaft mounting bracket includes a U-shaped clamping portion 1, designed to fit snugly around the rotating shaft 12 and provide a stable clamping force. It also includes connecting holes 2 running through both ends of the clamping portion 1. Bolts 3 are connected to the connecting holes 2, and nuts 4 are attached to the bolts 3. The combination of the bolts 3 and nuts allows the clamping force of the clamping portion 1 to be adjusted, ensuring that the rotating shaft 12 is securely clamped in the clamping hole 5. The clamping hole 5 is located on the inner side of the central portion of the clamping portion 1. The size and shape of this clamping hole 5 are carefully designed to fit snugly around the rotating shaft 12, effectively securing it.

[0037] One end of the clamping portion 1 extends from an extension section 6, which also includes a fixing bar 7 connected to the extension section 6. The fixing bar 7 has fixing holes 8 at each end, and the side panels 10 have through holes 14 corresponding to the fixing holes 8. Fastening screws are connected within the fixing holes 8 and through holes 14 to securely connect the side panels 10 to each other. The fixing bar 7 plays an important role in connecting the side panels 10 and the clamping portion 1 within the entire mounting bracket. The fixing bar 7 has fixing holes 8 at each end, and the side panels 10 have through holes corresponding to the fixing holes 8. By connecting fastening screws within the fixing holes 8 and through holes, the side panels 10 and the fixing bar 7 are securely fixed together. In this way, the clamping portion 1 is stably connected to the side panels 10 with the help of the fixing bar 7.

[0038] When the rotating shaft 12 is connected to the clamping hole 5, the clamping part 1 can tightly clamp the rotating shaft 12 to prevent the rotating shaft 12 from shaking or shifting during operation. At the same time, because the clamping part 1 is fixedly connected to the side plate 10 through the fixing bar 7, the rotating shaft 12 is also firmly fixed to the side plate 10, forming a stable fixed connection. This fixing method not only ensures the stability of the rotating shaft 12 during operation, but also facilitates installation and disassembly. When the rotating shaft 12 needs to be maintained or replaced, it is only necessary to loosen the bolts 3 and nuts, and tighten the screws to easily remove the rotating shaft 12 from the clamping hole 5 and perform the corresponding operation. After completing the maintenance or replacement, the rotating shaft 12 is reinstalled into the clamping hole 5 through simple operations, and the bolts 3, nuts and fastening screws are tightened to restore the normal operation of the equipment.

[0039] This shaft mounting bracket realizes a stable and fixed connection between the rotating shaft 12 and the side plate 10 through an ingenious design, providing a strong guarantee for the reliability and stability of the entire shaft mounting structure.

[0040] Extension section 6 is perpendicular to fixing bar 7 and is thickened to enhance its structural strength. This vertical arrangement provides a more secure connection between fixing bar 7 and side panel 10. When the screws secure fixing bar 7 to side panel 10, the vertical angle better withstands the various forces generated by the operating shaft 12 and roller 11, reducing loosening or deformation caused by an inappropriate angle.

[0041] Furthermore, the extended section 6 is thickened, significantly increasing its structural strength. This thickened section 6 can better withstand the reaction force generated by the clamping portion 1 clamping and securing the rotating shaft 12, ensuring that the entire mounting bracket will not deform or be damaged by the force during prolonged use. This increased structural strength also improves the reliability and stability of the mounting bracket, allowing the rotating shaft 12 to be more securely fixed to the side plate 10, ensuring the normal operation of the roller 11 conveying device.

[0042] It also includes a deformation groove 9 that passes through the middle of the clamping part 1. The width of the deformation groove 9 gradually decreases from the middle of the clamping part 1 to the end of the clamping part 1. A fastening ring 15 is threadedly connected to the rotating shaft 12. This unique design enables the clamping part 1 to deform more specifically when subjected to external extrusion force. When the fastening ring threaded on the rotating shaft 12 is tightened, the fastening ring will squeeze the clamping part 1. Due to the presence of the deformation groove 9, the clamping part 1 will deform into the deformation groove 9. In this process, extrusion will be formed between the inner wall of the clamping hole 5 and the rotating shaft 12. This extrusion makes the connection between the rotating shaft 12 and the clamping part 1 tighter and stronger, thereby forming a stable fixed connection.

[0043] This method of achieving a fixed connection by squeezing the clamping part 1 through a fastening ring has the following advantages. First, it increases the reliability of the fixed connection. On the basis of the original clamping and fixing of the rotating shaft 12 by the clamping part 1, the squeezing effect of the fastening ring further enhances the fixing effect, ensuring that the rotating shaft 12 will not loosen or shift during operation. Secondly, this design has a certain degree of adjustability. According to actual needs, the degree of deformation of the clamping part 1 can be adjusted by the degree of tightening the fastening ring, thereby controlling the extrusion force between the inner wall of the clamping hole 5 and the rotating shaft 12 to adapt to different working conditions and requirements. Finally, the special shape design of the deformation groove 9 makes the deformation of the clamping part 1 more uniform and controllable, avoiding the problem of structural damage or poor fixing effect caused by excessive local deformation.

[0044] The design of the deformation groove 9 and the fastening ring provides a more reliable, stable and adjustable fixed connection method for the shaft mounting bracket, further improving the performance and applicability of the entire shaft mounting structure.

[0045] The clamping hole 5 has a hexagonal cross-section. This hexagonal cross-section offers several advantages. The hexagonal shape better aligns with the rotating shaft 12, increasing the contact area and thus improving clamping stability. Compared to circular or other cross-section shapes, the hexagonal shape can restrict the rotating shaft 12 in multiple directions, preventing the rotating shaft 12 from rotating or shifting within the clamping hole 5. Furthermore, the hexagonal design ensures a more even distribution of the clamping force exerted by the clamping portion 1 on the rotating shaft 12, reducing localized stress concentration and extending the service life of the rotating shaft 12 and the clamping portion 1.

[0046] Chamfers 16 are provided on both sides of the upper end of the connecting groove 13, which can facilitate the entry of the rotating shaft 12 into the connecting groove 13. When installing the roller 11, the rotating shaft 12 needs to be moved downward from the upper side of the connecting groove 13 and installed into the connecting groove 13. With the existence of the chamfer, the rotating shaft 12 can slide in more smoothly during the process of entering the connecting groove 13, reducing resistance and jamming during the installation process. The chamfer design makes the installation operation more convenient and efficient, saving installation time and labor costs. At the same time, the chamfer also reduces the collision and wear between the rotating shaft 12 and the edge of the connecting groove 13, protects the structural integrity of the rotating shaft 12 and the connecting groove 13, and improves the reliability and stability of the entire conveying device.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
