Description

Technical Field

[0001] This utility model relates to the field of bushings, specifically an adjustable bushing that adapts to different shaft diameters. Background Technology

[0002] A bushing is a common mechanical component, mainly used for the connection, support, and protection of rotating shafts and their supporting components in mechanical equipment.

[0003] Chinese patent application number CN201620781323.3 provides a bushing. This solution has an extension, which serves two purposes: first, it provides a fixed position for the detachable connection between the left and right bushings; second, it increases the contact area between the ceramic bushing and the annular groove. Because the contact area is larger, the friction between the two is greater, so the ceramic bushing can be better fixed in the extension.

[0004] Traditional bushings are generally fixed-diameter structures, which can only be used for shafts of a specific diameter. When encountering equipment with different shaft diameters, the bushing needs to be replaced, causing inconvenience in operation and reducing maintenance and assembly efficiency. Therefore, an adjustable bushing that can adapt to different shaft diameters is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, traditional bushings are generally fixed inner diameter structures, which can only be used for rotating shafts of a specific diameter. When encountering equipment with different shaft diameters, the bushing needs to be replaced, causing inconvenience in operation and reducing maintenance and assembly efficiency. This utility model proposes an adjustable bushing that can adapt to different shaft diameters.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an adjustable bushing adapted to different shaft diameters, including a bushing body; an adjusting shaft ring is movably connected to the bottom end of the bushing body, and symmetrically distributed reinforcing blocks are fixedly connected to the upper end of the adjusting shaft ring. A locking rod is installed on the upper end of the reinforcing block, and an adjusting groove is opened in the inner end of the locking rod. A locking rod is slidably connected to the inner end of the adjusting groove, and a locking head is fixedly connected to the front end of the locking rod. By installing the adjusting shaft ring and the locking rod, the adjustment effect of the bushing body can be improved.

[0007] Preferably, a reset ring is fitted on the outer end of the snap-fit ​​rod. By installing the reset ring, the ease of connection of the bushing structure can be improved.

[0008] Preferably, one end of the locking rod extends to the outer end of the locking rod, and the rear end of the locking rod is fixedly connected to a limiting head. By installing the limiting head, the overall structure of the locking rod can be used more conveniently.

[0009] Preferably, the inner end of the limiting head is provided with a screw hole. By providing the screw hole, the assembly effect of the locking rod and the locking rod can be further improved.

[0010] Preferably, a guide ring is slidably connected to the inner end of the adjustment groove, and the guide ring is fixedly connected to the outer end of the snap-fit ​​rod. By setting the adjustment groove and the guide ring, the adjustment effect of the snap-fit ​​rod and the snap-fit ​​head is improved.

[0011] Preferably, the bottom end of the bushing body is provided with an assembly groove, which is symmetrically distributed. By setting the assembly groove, the assembly connection effect of the adjusting shaft ring can be improved.

[0012] Preferably, the inner end of the assembly groove is provided with a snap-fit ​​groove, which makes the assembly and installation of the bushing body more convenient.

[0013] Preferably, both ends of the bushing body are provided with positioning holes, and the inner end of the positioning hole is threadedly connected to a positioning element. The front end of the positioning element is threadedly connected to the screw hole. By installing the positioning element, the locking rod and the locking head can be locked together to prevent them from falling off.

[0014] The advantages of this utility model are:

[0015] 1. This utility model, through the structural design of the adjusting shaft ring and the locking rod, allows the adjusting shaft ring and locking rod, whose outer diameter is the same as the outer diameter of the shaft sleeve body but whose inner diameter is smaller than the inner diameter of the shaft sleeve body, to be inserted into the assembly groove at the bottom of the adjusting shaft ring when the shaft diameter needs to be adjusted. The locking rod is initially fixed to the assembly groove. After being locked in a certain position, the locking rod and locking head inside the locking rod, which are adjustable in position, are locked in the inner end of the locking groove under the reset force. At this time, the adjusting shaft ring is locked in the bottom of the shaft sleeve body, forming a shaft diameter adjustment structure for the shaft sleeve body. With the help of positioning parts to position the locking rod and other structures, the shaft sleeve can form an adjustable shaft diameter structure, which improves the adaptability of the shaft sleeve, avoids the need to replace the entire shaft sleeve when encountering equipment with different shaft diameters, reduces maintenance and assembly efficiency, and improves the adjustment effect of the shaft sleeve body.

[0016] 2. This utility model, through the structural design of the screw hole, has a screw hole at the outer end of the limiting head. After the locking rod and the locking head are adjusted and locked into the inner end of the locking groove, the positioning component is connected. The positioning component is then threadedly connected to the screw hole. This allows for secondary fixing after the positioning component is locked, avoiding the problem of the positioning component and the front locking head moving and separating from the locking groove, and further improving the assembly effect of the locking rod and the locking rod.

[0024] 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 scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses an adjustable bushing adaptable to different shaft diameters. (See also...) Figures 1-5An adjustable bushing adaptable to different shaft diameters includes a bushing body 1; an adjusting shaft ring 2 is movably connected to the bottom end of the bushing body 1, and symmetrically distributed reinforcing blocks 3 are fixedly connected to the upper end of the adjusting shaft ring 2. A locking rod 4 is installed on the upper end of the reinforcing block 3, and an adjusting groove 5 is opened on the inner end of the locking rod 4. A locking rod 6 is slidably connected to the inner end of the adjusting groove 5, and a locking head 7 is fixedly connected to the front end of the locking rod 6. By installing the adjusting shaft ring 2 and the locking rod 4, when the bushing body 1 needs to adjust the shaft diameter, the adjusting shaft ring 2, whose outer diameter is the same as the outer diameter of the bushing body 1, and whose inner diameter is smaller than the inner diameter of the bushing body 1, is inserted into the bottom end of the adjusting shaft ring 2. The clamping rod 4 is initially fixed to the assembly groove 12 at the inner end of the assembly groove 12. After being clamped to a certain position, the adjustable clamping rod 6 and clamping head 7 inside the clamping rod 4 are clamped again to the inner end of the clamping groove 13 under the reset force. At this time, the adjusting shaft ring 2 is clamped to the bottom of the bushing body 1, forming a shaft diameter adjustment structure for the bushing body 1. With the help of the positioning part 15, the clamping rod 6 and other structures are positioned, so that the bushing can form an adjustable shaft diameter structure, which improves the adaptability of the bushing, avoids the need to replace the entire bushing when encountering equipment with different shaft diameters, reduces maintenance and assembly efficiency, and improves the adjustment effect of the bushing body 1.

[0027] Reference Figures 1-3 The outer end of the snap-fit ​​rod 6 is fitted with a reset ring 8. By installing the reset ring 8, which is an elastic reset structure, the reset ring 8 can be used to adjust the position of the snap-fit ​​rod 6. When the snap-fit ​​rod 6 moves to the snap-fit ​​groove 13, it can be reset so that the snap-fit ​​head 7 is snapped into the inner end of the snap-fit ​​groove 13. This makes the assembly of the adjusting shaft ring 2 more convenient and improves the convenience of the connection of the shaft sleeve structure.

[0028] Reference Figure 1 and Figure 3 One end of the snap-fit ​​rod 6 extends to the outer end of the snap-fit ​​rod 4, and the rear end of the snap-fit ​​rod 6 is fixedly connected to the limiting head 10. By installing the limiting head 10, the limiting head 10 can form a connection and limiting structure at the outer end of the snap-fit ​​rod 6, making the overall structure of the snap-fit ​​rod 6 more convenient to use.

[0029] Reference Figure 1 , Figure 3 and Figure 4 The inner end of the limiting head 10 is provided with a screw hole 11. By setting the screw hole 11, a screw hole 11 is also provided at the outer end of the limiting head 10. When the locking rod 6 and the locking head 7 are adjusted and locked into the inner end of the locking groove 13, the positioning part 15 is connected. The positioning part 15 is then threadedly connected to the screw hole 11. After the positioning part 15 is locked, it can be fixed again to avoid the positioning part 15 and the front locking head 7 from moving and separating from the locking groove 13, which further improves the assembly effect of the locking rod 6 and the locking rod 4.

[0030] Reference Figure 3 The inner end of the adjustment groove 5 is slidably connected to a guide ring 9, which is fixedly connected to the outer end of the snap-fit ​​rod 6. By setting the adjustment groove 5 and the guide ring 9, the adjustment groove 5 has a structure with a larger diameter in the middle and a smaller diameter at both ends. The two ends of the snap-fit ​​rod 6 are slidably connected to the slot with the smaller diameter, while the guide ring 9 and the adjustment structure are slidably connected to the middle of the adjustment groove 5. This can prevent the snap-fit ​​rod 6 and the snap-fit ​​head 7 from falling off when adjusting their positions, thus improving the adjustment effect of the snap-fit ​​rod 6 and the snap-fit ​​head 7.

[0031] Reference Figure 2 and Figure 4 The bottom end of the bushing body 1 is provided with an assembly groove 12. The assembly grooves 12 are symmetrically distributed. By setting the assembly grooves 12, when the adjusting shaft ring 2 is assembled, the locking rod 4 is inserted into the inner end of the assembly groove 12, so that the adjusting shaft ring 2 can be initially connected during assembly, which makes it easier to find the right position for more accurate assembly and improves the assembly connection effect of the adjusting shaft ring 2.

[0032] Reference Figure 4 The inner end of the assembly groove 12 is provided with a snap-fit ​​groove 13. By setting the snap-fit ​​groove 13, the snap-fit ​​groove 13 can be snapped with the snap-fit ​​head 7. With the snap-fit ​​rod 4, the adjusting shaft ring 2 and the bushing body 1 can have multiple connection snap-fit ​​structures, making the assembly and installation of the bushing body 1 more convenient.

[0033] Reference Figures 1-4 Both ends of the bushing body 1 are provided with positioning holes 14. The inner end of the positioning hole 14 is threadedly connected to a positioning element 15. The front end of the positioning element 15 is threadedly connected to the screw hole 11. By installing the positioning element 15, which is a commonly used assembly and fixing part of the bushing assembly, the positioning element 15 can form a limiting structure on the outside of the limiting head 10, or connect with the screw hole 11 provided on the limiting head 10, so that the locking rod 6 and the locking head 7 can be locked together to prevent them from falling off.

[0034] Working principle: When the shaft diameter of the bushing body 1 needs to be adjusted, the locking rod 4 at the upper end of the adjusting shaft ring 2 is aligned with the assembly groove 12 and pressed down. The locking rod 4 is inserted into the inner end of the assembly groove 12, which allows the adjusting shaft ring 2 to be initially connected during assembly, making it easier to find the correct position for more precise assembly. The locking rod 4 is initially fixed to the assembly groove 12. After being locked in a certain position, the reset ring 8 is an elastic reset structure. The reset ring 8, together with the locking rod 6, can be easily adjusted in position. When the locking rod 6 moves to the position of the locking groove 13, it can be reset, so that the locking head 7 is locked in the inner end of the locking groove 13, which makes the assembly of the adjusting shaft ring 2 more convenient. Under the reset force, the locking rod 6 and the locking head 7 inside the locking rod 4 are locked in the inner end of the locking groove 13 again. At this time, the adjusting shaft ring 2 is locked at the bottom of the bushing body 1, forming a shaft diameter adjustment structure for the bushing body 1.

[0035] After assembly and snap-fit, the positioning component 15 is connected to the positioning hole 14 as needed. By assembling the positioning component 15 and the positioning hole 14, the positioning component 15 can form a limiting structure on the outside of the limiting head 10. Alternatively, the positioning component 15 can be threadedly connected to the screw hole 11 provided on the limiting head 10. This allows for secondary fixation after the positioning component 15 is snap-fitted, preventing the positioning component 15 and the front end snap-fit ​​head 7 from moving and separating from the snap-fit ​​groove 13, thus enabling the bushing to achieve shaft diameter adjustment.

[0036] The contents not described in detail in this specification do not improve upon this application and are all prior art known to those skilled in the art, and therefore are not described in detail.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
