Description

Technical Field

[0001] The utility model relates to the technical field of mounting brackets, in particular to a bracket fixedly mounted on a shaft. Background Art

[0002] In numerous mechanical structures and devices, brackets serve as crucial connecting and supporting components, playing a crucial role. A widely used annular bracket, attached to a shaft, is known in the prior art. This bracket features an opening on one side and fixing portions on either side of the opening. These brackets are connected using bolts and nuts. The shaft is placed inside the bracket and tightened, allowing the bracket to clamp onto the shaft, creating a secure connection.

[0003] However, this fixing method has significant shortcomings. Relying solely on the coordination of bolts and nuts to achieve a fixed connection, the stability of the entire connection depends largely on the precision of the bolt and nut fit. In actual use, the bolt and nut fit can easily loosen due to long-term operation of the equipment, vibration, and various external environmental factors. Once the bolts and nuts loosen, the bracket will loosen, which in turn affects the normal operation of the equipment. This loose bracket problem can lead to a series of adverse consequences, such as reducing the accuracy of the equipment, affecting the performance of the equipment, and even causing equipment failure, causing great inconvenience and safety hazards to production and use.

[0004] Therefore, in order to solve the problem of easy loosening of the existing shaft-connected bracket, a new bracket design is urgently needed to improve the stability and reliability of the connection between the bracket and the shaft and increase the difficulty of loosening. Summary of the Invention

[0005] In view of the problems pointed out in the background technology, the present invention proposes a bracket to solve the above technical problems.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] A bracket includes a tubular connecting portion, wherein the connecting portion is provided with two first disconnecting grooves, and the two first disconnecting grooves are arranged at intervals in the axial direction of the connecting portion; a second disconnecting groove is provided on the connecting portion between the two first disconnecting grooves, and the second disconnecting groove is arranged along the axial direction of the connecting portion, and the second disconnecting groove is arranged through the inner and outer sides of the connecting portion; the connecting portions on both sides of the second disconnecting groove are provided with fixing portions, and the fixing portions are provided with fixing holes.

[0008] The present invention is further configured such that protruding thickened portions are provided on the inner side surfaces of the connecting portions on both sides of the second disconnecting groove.

[0009] The present invention is further configured such that arc chamfers are respectively provided at both ends of the thickened portion in the axial direction of the connecting portion.

[0010] The utility model is further configured as follows: a mounting hole is provided on the connecting portion, the mounting hole and the connecting portion are coaxially arranged, the diameter of the mounting hole is larger than the inner diameter of the connecting portion, the upper end of the mounting hole passes through the upper side of the connecting portion, and the lower end of the mounting hole passes through the two first disconnecting grooves. A clamping tube is installed in the mounting hole, the outer diameter of the clamping tube is equal to the inner diameter of the mounting hole, and the inner diameter of the clamping tube is equal to the inner diameter of the connecting portion.

[0011] The utility model is further configured such that the lower end of the clamping tube is provided with a third disconnecting groove running through both inner and outer sides thereof, a plurality of third disconnecting grooves are provided and are spaced apart in the circumferential direction of the clamping tube, and the clamping tubes between adjacent third disconnecting grooves are clamping strips.

[0012] The utility model is further configured such that the lower end of the clamping strip is bent inwards.

[0013] The present invention is further configured such that a mounting platform is provided at the upper end of the connecting portion, and a connecting hole is provided on the mounting platform.

[0014] The present invention is further configured such that a reinforcing plate rib is provided between the mounting platform and the connecting portion.

[0015] By adopting the above technical solution, the beneficial effects of the utility model are:

[0016] First, by providing the first and second disconnect grooves and the fixing portion on the connecting portion, the connecting portion can tighten and clamp the shaft rod when tightening the bolts and nuts. The friction formed by the connection between the tubular connecting portions on both sides of the fixing portion and the shaft rod can prevent the connecting portion from loosening easily when the bolts and nuts loosen, thereby increasing the difficulty of loosening. Secondly, protruding thickened portions are provided on the inner side surfaces of the connecting portion on both sides of the second disconnect groove. When the shaft rod is inserted, the connecting portion can elastically clamp the shaft rod, further increasing the difficulty of loosening. Furthermore, the circular chamfers at both ends of the axial thickened portion of the connecting portion facilitate the installation of the shaft rod and reduce shaft wear. In addition, the mounting hole on the connecting portion and the internal clamping tube, with the help of multiple clamping strips with inwardly bent lower ends, can elastically clamp the shaft rod, further reducing the possibility of loosening. Finally, the mounting platform and connecting hole at the upper end of the connecting portion can be used to install other equipment. The reinforcing plate ribs between the mounting platform and the connecting portion enhance the connection strength and stability, making the overall structure of the bracket more reliable and adaptable to a variety of complex usage environments.

DETAILED DESCRIPTION

[0025] 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.

[0026] Reference as follows Figure 1-6 The utility model is described as follows:

[0027] Example: A stent includes a tubular connecting portion 1. Two first breakout grooves 2 are carefully arranged on the connecting portion 1, arranged radially along the connecting portion 1. Furthermore, the two first breakout grooves 2 are spaced apart in the axial direction of the connecting portion 1 and located inboard of the axial ends of the connecting portion 1. This design allows the connecting portion 1 to have a certain degree of deformability at specific locations.

[0028] A crucial second disconnect groove 3 is located on the connecting portion 1 between the two first disconnect grooves 2. This second disconnect groove 3 runs axially along the connecting portion 1 and extends through both the inner and outer sides of the connecting portion 1. Fixing portions 4 are located on both sides of the connecting portion 1, each of which has a fixing hole 5.

[0029] In actual use, the shaft is connected to the inner side of the connecting portion 1. By connecting the bolts and nuts in the fixing holes 5 and then tightening the bolts and nuts, the connecting portions 1 on both sides of the second disconnection groove 3 will gradually tighten and then clamp and hold the shaft, so that the bracket can be fixedly connected to the shaft.

[0030] This technical solution offers significant advantages. When the tubular connecting portions 1 on either side of the fixing portion 4 are connected to the shaft, friction is generated between them. This friction helps maintain the connection between the bracket and the shaft. If the bolts and nuts become loose, the friction between the shaft and the connecting portions prevents the connection from becoming loose. This friction significantly increases the difficulty of loosening the connection.

[0031] Specifically, the tubular connecting portion 1 provides a stable structural foundation for connecting the bracket to the shaft. The two first breakaway grooves 2 provide a certain amount of flexibility at the axial ends of the connecting portion 1, allowing the connecting portion 1 to better adapt to changes in the size and shape of the shaft during installation and use. Furthermore, because they are located inward of the axial ends of the connecting portion 1, they do not significantly affect the overall strength of the connecting portion 1, while still allowing for some deformation when needed.

[0032] The second disconnect groove 3 is the key to the fixed connection of the entire bracket. When the bolt and nut are tightened in the fixing hole 5, the connecting parts 1 on both sides of the second disconnect groove 3 will be squeezed and tightened. This tightening force enables the connecting parts 1 to tightly clamp the shaft, thereby achieving a secure connection.

[0033] The fixing holes 5 on the fixing portion 4 provide precise locations for the bolt and nut connections, ensuring a stable and reliable connection. Furthermore, the friction between the tubular connecting portions 1 on either side of the fixing portion 4 and the shaft provides a backup in the event that the bolts and nuts become loose. Even if the bolt and nut connection becomes loose to some extent, the friction between the shaft and the connecting portions prevents the connecting portions from easily coming loose from the shaft, effectively improving the stability and safety of the connection between the bracket and the shaft.

[0034] In summary, the design of this bracket cleverly combines multiple structural features. Through the synergistic effect of the circular tubular connecting part, the first disconnecting groove, the second disconnecting groove, the fixing part and the fixing hole, as well as the assistance of the friction force between the shaft and the connecting part, it effectively solves the problem of easy loosening of the bracket in the existing technology, and provides a more reliable connection method for various equipment and mechanical structures that require shaft connection. Example

[0035] The inner side surfaces of the connecting portion 1 on either side of the second disconnect groove 3 are provided with protruding thickened portions 6. These thickened portions 6 serve an important purpose. When the shaft is inserted into the connecting portion 1, the thickened portions 6 block the connecting portion 1 on either side of the second disconnect groove 3, causing it to expand and deform. This expansion allows the connecting portion 1 in this portion to be elastically clamped to the shaft, further increasing the difficulty of loosening the connecting portion 1.

[0036] Specifically, the thickened portion 6 increases the contact area and pressure between the connecting portion 1 and the shaft. When the shaft is inserted, the thickened portion 6 forces the connecting portion 1 to deform. This deformation generates an elastic force that tightly wraps the connecting portion 1 around the shaft. This elastic clamping not only increases friction but also makes the connection more stable and reliable. Even if the bolt and nut become loose, this elastic clamping prevents the connecting portion 1 from easily falling off the shaft.

[0037] In addition, in the axial direction of the connecting portion 1, arc chamfers 7 are respectively provided at both ends of the thickened portion 6. Providing the arc chamfers 7 has many advantages. First, the arc chamfers 7 can facilitate the installation of the shaft rod. During the installation process, the shaft rod can slide through the arc chamfers 7 more smoothly and enter the interior of the connecting portion 1. Without the arc chamfers 7, the shaft rod may encounter obstacles during the insertion process, increasing the difficulty of installation. Secondly, the arc chamfers 7 can also reduce the wear on the shaft rod. During the insertion and removal of the shaft rod, the arc chamfers 7 can prevent the edge of the connecting portion 1 from scratching and damaging the shaft rod, thereby extending the service life of the shaft rod.

[0038] In summary, the design of the thickened portion 6 and the arc-shaped chamfer 7 further enhances the stability and reliability of the connection between the bracket and the shaft. The thickened portion 6 strengthens the connection through elastic clamping, while the arc-shaped chamfer 7 facilitates shaft installation and reduces wear on the shaft. These design features make this bracket more practical and valuable in various applications requiring shaft connections. Example

[0039] Connecting portion 1 is provided with a mounting hole 8, coaxially arranged with connecting portion 1. The diameter of mounting hole 8 is larger than the inner diameter of connecting portion 1. The upper end of mounting hole 8 extends through the upper side of connecting portion 1, while the lower end of mounting hole 8 extends through two first disconnecting grooves 2. A clamping tube 9 is mounted within mounting hole 8. The outer diameter of clamping tube 9 is equal to the inner diameter of mounting hole 8, and the inner diameter of clamping tube 9 is equal to the inner diameter of connecting portion 1. The upper end of clamping tube 9 is fixedly connected to connecting portion 1, and the lower end of clamping tube 9 is provided with a third disconnecting groove 10 extending through both the inner and outer sides thereof. Multiple third disconnecting grooves 10 are provided and spaced circumferentially around clamping tube 9. Clamping strips 11 are formed between adjacent third disconnecting grooves 10. The lower ends of clamping strips 11 are bent inward.

[0040] By adopting this technical solution, the bracket can achieve elastic clamping of the shaft via the clamping tube 9. Specifically, when the shaft is inserted into the connecting portion 1 and the clamping tube 9, the inwardly bent lower end of the clamping strip 11 causes the shaft to push against the strip 11, generating an outward elastic deformation force. This elastic deformation forces the strip 11 to press tightly against the shaft, thereby increasing the friction and clamping force between the bracket and the shaft.

[0041] This elastic clamping method further reduces the risk of the bracket loosening. Even if the bolts and nuts become loose, the elastic clamping action of the clamping tube 9 on the shaft maintains relative stability between the bracket and the shaft. Furthermore, the arrangement of the mounting holes 8 provides a stable mounting position for the clamping tube 9, ensuring its effective function. Multiple third breakout slots 10 divide the clamping tube 9 into multiple clamping strips 11, allowing it to more flexibly adapt to shafts of varying diameters, enhancing the bracket's versatility.

[0042] In summary, by providing the mounting hole 8 and the clamping tube 9 on the connecting portion 1 and utilizing the elastic clamping effect of the clamping strip 11, the bracket can provide a more reliable fixing effect when connected to the shaft, further reducing the possibility of loosening.

[0043] The upper end of the connecting portion 1 is provided with a mounting platform 12, which is provided with a connection hole 13 for mounting other equipment. This connection hole 13 can be used to mount other equipment. The arrangement of the mounting platform 12 provides a stable platform for connecting other equipment, allowing the bracket to be connected to the shaft and effectively connected and fixed to other equipment.

[0044] Reinforcing ribs 14 are provided between the mounting platform 12 and the connecting portion 1. These ribs play a crucial role, enhancing the strength and stability of the connection between the mounting platform 12 and the connecting portion 1. During actual use, when other equipment mounted on the mounting platform 12 generates forces, the reinforcing ribs 14 effectively disperse these forces, preventing deformation or damage at the connection between the mounting platform 12 and the connecting portion 1.

[0045] 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.
