[0002] A rod end joint bearing is a joint bearing with a rod end or mounted on a rod end, and is a type of joint bearing. Currently, when securing a rod end joint bearing to a hydraulic rod, most methods involve turning a knob on the rod end joint bearing, causing the clamping block on the rod end joint bearing to clamp the hydraulic rod, and securing the rod end joint bearing to the hydraulic rod through the clamping force. For example, a hydraulic rod end joint bearing disclosed in Chinese Patent Publication No. CN210397423U, however, requires the user to turn two or more knobs to loosen or clamp the clamping block when disassembling or assembling the rod end joint bearing from the hydraulic rod, as one knob can only adjust the position of one clamping block. This results in the rod end joint bearing being difficult to assemble or disassemble from the hydraulic rod. Utility Model Content

[0003] The purpose of the utility model is to provide a hydraulic rod end joint bearing, which solves the problem that when disassembling and assembling the rod end joint bearing on the hydraulic rod, since one knob can only adjust the position of one clamping block, the user needs to turn two or more knobs to loosen or clamp the clamping block, thereby making it difficult to disassemble and assemble the rod end joint bearing and the hydraulic rod.

[0004] The technical solutions adopted by this utility model are as follows:

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1 to 9As shown, a hydraulic rod end joint bearing includes a bearing body 1, a threaded cylinder 2 is fixedly connected to the bottom of the bearing body 1, a nut 3 is threadedly connected to the surface of the threaded cylinder 2, a first connecting column 4 is fixedly connected to the bottom of the nut 3, a pressing ring 5 is fixedly connected to the bottom of the first connecting column 4, an upper conical cylinder 6 is fitted on the inner wall of the pressing ring 5 and the surface of the threaded cylinder 2, a second connecting column 7 is fixedly connected to the bottom of the upper conical cylinder 6, a lower conical cylinder 8 is fixedly connected to the bottom of the second connecting column 7, square holes 9 are opened on the left and right sides of the threaded cylinder 2, and a fixing bracket 10 is fitted on the inner wall of the square hole 9, the inner wall of the upper conical cylinder 6 and the inner wall of the lower conical cylinder 8.

[0029] Among them, the bearing body 1 includes a bearing outer ring 101, a retaining frame 102, a spherical roller 103, a bearing inner ring 104 and a bearing rod 105. The inner wall of the bearing outer ring 101 fits with the surface of the retaining frame 102, and the inner wall of the retaining frame 102 fits with the surface of the bearing inner ring 104. The inner wall of the bearing outer ring 101, the inner wall of the retaining frame 102 and the surface of the bearing inner ring 104 all fit with the surface of the spherical roller 103. The top of the bearing rod 105 is fixedly connected to the bottom of the bearing outer ring 101.

[0030] The fixed bracket 10 includes a square column 1001, an arc-shaped column 1002 and a magnet 1003. One side of the square column 1001 is fixedly connected to the side of the arc-shaped column 1002. The surface of the arc-shaped column 1002 is in contact with the inner wall of the threaded cylinder 2. The other side of the square column 1001 is fixedly connected to the side of the magnet 1003. The inner wall of the upper conical cylinder 6 and the inner wall of the lower conical cylinder 8 are both in contact with the surface of the magnet 1003. The suction force of the magnet 1003 on the upper conical cylinder 6 and the suction force of the magnet 1003 on the lower conical cylinder 8 are both greater than the gravity of the fixed bracket 10.

[0031] It should be noted that when the user turns the nut 3, the pressing ring 5 can move upward or downward through the cooperation of the nut 3 and the threaded cylinder 2. When the pressing ring 5 moves downward, the pressure of the pressing ring 5 on the upper cone cylinder 6 can make the upper cone cylinder 6 and the lower cone cylinder 8 press the magnetic block 1003 on the fixed bracket 10, and make the arc column 1002 on the fixed bracket 10 clamp the hydraulic rod in the threaded cylinder 2. When the pressing ring 5 moves upward, the pressing ring 5 no longer presses the upper cone cylinder 6, thereby causing the arc column 1002 to loosen the hydraulic rod and move the hydraulic rod out of the threaded cylinder 2. At the same time, the magnetic block 1003 can fit tightly with the upper cone cylinder 6 and the lower cone cylinder 8 through suction, and then when the upper cone cylinder 6 and the lower cone cylinder 8 move upward, the distance between the left and right arc columns 1002 will gradually increase.

[0032] like Figures 1 to 6 As shown, the bottom of the bearing rod 105 and the inner wall of the threaded barrel 2 are fixedly connected to the limiting column 11, which limits the hydraulic rod inserted into the threaded barrel 2.

[0033] like Figures 1 to 10 As shown, the upper surface of the nut 3 is fixedly connected to a cylinder 12, the inner wall of the cylinder 12 fits with the surface of the threaded cylinder 2, a circular hole 13 is opened on the front of the cylinder 12, and a strip hole 14 is opened on the surface of the threaded cylinder 2. The inner wall of the strip hole 14 and the inner wall of the circular hole 13 are both fitted with a positioning column 15, and the front of the positioning column 15 is fixedly connected to a C-shaped spring clip 16, and the inner wall of the C-shaped spring clip 16 fits with the surface of the cylinder 12.

[0034] The elastic force of the C-shaped spring piece 16 is greater than the gravity of the C-shaped spring piece 16 and the positioning post 15 .

[0035] It should be noted that when the C-shaped spring clip 16 is sleeved on the cylinder 12, the positioning column 15 can be fixed in the circular hole 13 and the strip hole 14 through the elastic force of the C-shaped spring clip 16, and the nut 3 cannot be rotated through the cooperation of the positioning column 15, the circular hole 13 and the strip hole 14, so that after the fixing bracket 10 clamps the hydraulic rod, the nut 3 can be locked through the cooperation of the cylinder 12, the circular hole 13, the strip hole 14, the positioning column 15 and the C-shaped spring clip 16, so that the fixing bracket 10 and the hydraulic rod will not loosen, and the rod end joint bearing and the hydraulic rod are fixed more firmly.

[0036] The operating principle of the present invention is as follows: first, the C-shaped spring piece 16 is removed from the cylinder 12; then, by rotating the nut 3, the nut 3 is moved up to a suitable position; and by moving the upper cone 6 and the lower cone 8 upward, the arc column 1002 is fitted with the inner wall of the threaded cylinder 2; then, the threaded cylinder 2 is put on the hydraulic rod; and by moving the upper cone 6 and the lower cone 8 downward, the arc column 1002 is fitted with the hydraulic rod.

[0037] Then, by rotating the nut 3, the pressing ring 5 presses the upper cone cylinder 6. At the same time, the pressure of the pressing ring 5 on the upper cone cylinder 6 can make the upper cone cylinder 6 and the lower cone cylinder 8 press the magnetic block 1003 on the fixed bracket 10, and make the arc column 1002 on the fixed bracket 10 clamp the hydraulic rod in the threaded cylinder 2. At this time, the rod end joint bearing can be fixed on the hydraulic rod through the clamping force of the arc column 1002 on the hydraulic rod.

[0038] After the rod end joint bearing is fixed on the hydraulic rod, the positioning column 15 is inserted into the circular hole 13 and the strip hole 14, and the C-shaped spring piece 16 is put on the cylinder 12. At this time, the positioning column 15 can be fixed in the circular hole 13 and the strip hole 14 by the elastic force of the C-shaped spring piece 16, and the nut 3 cannot rotate through the cooperation of the positioning column 15, the circular hole 13 and the strip hole 14.

[0039] When the rod end joint bearing is separated from the hydraulic rod, first remove the C-shaped spring piece 16 from the cylinder 12, then move the nut 3 to a suitable position by rotating the nut 3, and loosen the hydraulic rod by moving the upper cone 6 and the lower cone 8 upwards, so that the arc column 1002 can be separated from the hydraulic rod.

[0040] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
