Description

Technical Field

[0001] This utility model relates to the field of locking sleeve technology, and in particular to a locking sleeve that is easy to lock. Background Technology

[0002] The adapter sleeve is the most commonly used component for positioning bearings with tapered bores on cylindrical shafts. This type of sleeve can be used on both smooth and stepped shafts. It is easy to install and does not require additional fixing to the shaft. When used on a smooth shaft, the bearing can be positioned at any point on the shaft. When used with a stepped ring on a stepped shaft, the bearing can be precisely positioned axially, facilitating bearing removal. The adapter sleeve is used to fix self-aligning bearings (self-aligning ball bearings, self-aligning roller bearings) on shoulderless shafts. It has a simple structure, reliable operation, and convenient bearing replacement. It is widely used in industries such as textiles, light industry, papermaking, metallurgy, belt conveyors, and conveyor equipment.

[0003] Existing patent CN219692043U discloses a locking sleeve with a locking structure, including a bushing, a locking component on the outer wall of the bushing, and a reinforcing component outside the locking component. The locking component includes a threaded surface on the lower outer wall of the bushing, with a threaded ring threadedly connected to the threaded surface. A washer is fitted onto the outer wall of the bushing, and multiple through holes are equidistantly formed on the outer wall of the bushing. Each of the multiple through holes has a rubber block inserted into it. The beneficial effect of this invention is that by fitting a collar onto the surface of the bushing and pressing the inclined surface of the rubber block with the collar, the bushing stably presses the rubber block against the surface of the shaft. Then, the bearing is fitted onto the surface of multiple pressing strips, and the bearing presses the pressing strips so that the rubber strips extend from the openings and fit against the bearing, thereby fixing the bearing and preventing slippage between the bearing, bushing, and main shaft, and preventing the bearing and locking sleeve from shifting.

[0004] In practical applications, although it can prevent the spindle from sliding between the spindle and the components and prevent the bearings and the adapter sleeve from shifting, when the adapter sleeve is tightened, it cannot lock the adapter sleeve, nor can it squeeze and limit the components, which will cause the components to loosen and affect their use. Utility Model Content

[0005] This utility model discloses a locking sleeve that is easy to lock, aiming to solve the technical problem that the locking sleeve cannot be squeezed and positioned during the positioning process, which affects subsequent use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A locking sleeve for easy locking includes a positioning ring, a threaded tube fixedly installed on one side of the positioning ring, a positioning tube threadedly connected to the surface of the threaded tube, and a threaded ring threadedly connected to the top of the positioning tube.

[0008] The positioning tube is equipped with a positioning component inside. The positioning component includes an annular groove formed above the positioning tube. A positioning rod is inserted into the inner wall of the annular groove. One end of the positioning rod is located inside the annular groove. A triangular plate is fixedly installed at the end of the positioning rod located inside the annular groove. A tension spring is arranged around the surface of the positioning rod. A wedge plate is fixedly installed at the bottom of the screw ring.

[0009] With the positioning component in place, the wedge plate on the screw ring presses against the triangular plate during use, which in turn causes the positioning rod to move into the positioning tube. This locks the component during tightening, preventing the locking sleeve from loosening during subsequent use and maintaining the stability of the locking sleeve.

[0010] In a preferred embodiment, one end of the tension spring is fixedly connected to the inner wall of the annular groove, and the other end of the tension spring is fixedly connected to one side of the triangular plate.

[0011] The positioning rod on the triangular plate can be reset by the tension spring, making it easy to retract the positioning rod into the positioning tube later.

[0012] In a preferred embodiment, the positioning tube has a positioning hole for the positioning rod to pass through, the inside of the positioning hole is slidably connected to the surface of the positioning rod, the positioning hole is connected to the annular groove, and the bottom of the triangular plate is slidably connected to the inner bottom wall of the annular groove.

[0013] The positioning hole allows for a limit operation on the positioning rod during use, preventing it from shifting during subsequent use.

[0014] In a preferred embodiment, a screw is inserted into the surface of the screw ring, and a rotating block is fixedly installed at one end of the screw. The surface of the rotating block is provided with anti-slip texture.

[0015] The screws and rotating blocks make it easy to rotate the screws and position the rings during use.

[0016] In a preferred embodiment, the surface of the screw ring has a groove, and the screw ring has a threaded hole for the screw to pass through, and the threaded hole is threadedly connected to the screw.

[0017] The threaded holes allow for easy tightening and loosening of screws, and facilitate the installation of the set sleeve.

[0018] In a preferred embodiment, a bolt is inserted into the surface of the positioning ring, one end of the bolt has a hexagonal hole, and the surface of one end of the bolt is rounded.

[0019] By using the screws and bolts, the spindle can be positioned during use, ensuring that one end of the bolt or screw contacts the surface of the spindle. This prevents the components on the adapter sleeve from loosening on the spindle during use, thus maintaining the ease of use of the adapter sleeve and improving its efficiency.

[0020] In a preferred embodiment, the positioning ring has a threaded hole for the bolt to pass through, the threaded hole is threadedly connected to the bolt, and the surfaces of the triangular plate and the wedge plate are both rounded.

[0021] The bolts allow for convenient limiting during use, improving the installation efficiency of the locking sleeve.

[0022] As can be seen from the above, the locking sleeve provided by this utility model has the following technical effects.

[0023] Firstly, through the positioning component, during use, the wedge plate on the screw ring presses against the triangular plate, which in turn causes the positioning rod to move into the positioning tube. This locks the component during tightening, preventing the locking sleeve from loosening during subsequent use and maintaining the stability of the locking sleeve.

[0024] Secondly, the screws and bolts allow for positioning of the spindle during use, ensuring that one end of the bolt or screw contacts the surface of the spindle. This prevents the components on the adapter sleeve from loosening on the spindle during use, thus maintaining the ease of use of the adapter sleeve and improving its efficiency.

The screw 6 and the rotating block 7 facilitate the rotation of the screw 6 and the positioning of the screw ring 4 during use. The surface of the screw ring 4 is provided with a groove and a threaded hole for the screw 6 to pass through. The threaded hole is threadedly connected to the screw 6. The threaded hole facilitates the tightening and loosening of the screw 6 and facilitates the installation of the locking sleeve.

[0033] Reference Figure 3 and Figure 4The positioning tube 3 has a positioning assembly 5 inside. The positioning assembly 5 includes an annular groove formed above the positioning tube 3. A positioning rod 500 is inserted into the inner wall of the annular groove. One end of the positioning rod 500 is located inside the annular groove. A triangular plate 501 is fixedly installed at the end of the positioning rod 500 located inside the annular groove. A tension spring 502 is arranged around the surface of the positioning rod 500. A wedge plate 503 is fixedly installed at the bottom of the screw ring 4. During use, the wedge plate 503 on the screw ring 4 presses against the triangular plate 501, which in turn causes the positioning rod 500 to move towards the positioning tube 3. The internal movement of the locking sleeve locks the component during tightening, preventing it from loosening during subsequent use and maintaining its stability. The positioning tube 3 has a positioning hole for the positioning rod 500 to pass through. The inside of the positioning hole is slidably connected to the surface of the positioning rod 500. The positioning hole is connected to the annular groove. The bottom of the triangular plate 501 is slidably connected to the inner bottom wall of the annular groove. The positioning hole can limit the positioning rod 500 during use, preventing it from shifting during subsequent use.

[0034] Reference Figure 4 In a preferred embodiment, one end of the tension spring 502 is fixedly connected to the inner wall of the annular groove, and the other end of the tension spring 502 is fixedly connected to one side of the triangular plate 501. The tension spring 502 can reset the positioning rod 500 on the triangular plate 501, making it convenient to put the positioning rod 500 into the positioning tube 3 later.

[0035] Reference Figure 2 In a preferred embodiment, a bolt 8 is inserted into the surface of the positioning ring 1. One end of the bolt 8 has a hexagonal hole and the surface of one end of the bolt 8 is rounded. The screw 6 and the bolt 8 can be used to position the spindle during use, so that one end of the bolt 8 and the screw 6 contacts the surface of the spindle. This prevents the components on the locking sleeve from loosening on the spindle during use, thus maintaining the ease of use of the locking sleeve and improving its efficiency.

[0036] Reference Figure 2 and Figure 4 In a preferred embodiment, the positioning ring 1 has a threaded hole for the bolt 8 to pass through, and the threaded hole is threadedly connected to the bolt 8. The surfaces of the triangular plate 501 and the wedge plate 503 are both rounded. The bolt 8 is conveniently positioned during use, which improves the installation efficiency of the locking sleeve.

[0037] Working principle: When it is needed for installation and positioning, the positioning ring 1 is placed on the surface of the spindle. Then, the threaded tube 2 is threaded to the positioning tube 3, and the positioning tube 3 is threaded to the screw ring 4. The wedge plate 503 on the screw ring 4 presses against the triangular plate 501, causing the positioning rod 500 on one side of the triangular plate 501 to move into the positioning tube 3, thereby preventing the parts from loosening during subsequent use. At the same time, the screw 6 and bolt 8 are tightened so that one end of the screw 6 and bolt 8 contacts the surface of the spindle, thereby achieving positioning.
