DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. Example
[0026] In one embodiment, Figure 1-Figure 5As shown, a hinge for a multi-degree-of-freedom platform includes a first base 1 and a second base 2, and also includes an installation component and a disassembly component. The first base 1 and the second base 2 have opposite side walls each provided with a rotating base hole, and the inner side wall of the rotating base hole is slidably connected to a rotating base 7, and the side wall of the rotating base 7 located outside the sliding connection hole is fixedly connected to a rotating block 6 through a connecting rod, and the upper surface of the rotating block 6 is rotatably connected to a mounting seat 3 through a bearing, the side wall of the first base 1 is fixedly connected to two opposite second mounting blocks 5, and the side wall of the second base 2 is fixedly connected to two opposite first mounting blocks 4, and the side walls of the two second mounting blocks 5 are fixedly connected to plug blocks 11, and the side walls of the two first mounting blocks 4 close to the second mounting blocks 5 are provided with plug block grooves corresponding to the plug blocks 11, the installation component is arranged in the plug block groove for quickly completing the hinge installation, and the disassembly component is arranged at the side wall of the first mounting block 4 for quickly completing the hinge disassembly.
[0027] In one embodiment, Figure 5 As shown, the installation assembly includes a block 12, the inner side walls of the two block slots are provided with block slots, the inner side walls of the two block slots are slidably connected with the block 12, the side walls of the two blocks 11 are provided with grooves corresponding to the block 12, the block 12 is engaged with the grooves of the block 11, and the side wall of the block 12 located in the block slot is fixedly connected with a damping spring. First, the arc sealing strip 8 is placed in the rotating base hole of the first base 1 and the second base 2, and then the block 11 of the second installation block 5 is inserted into the block slot of the first installation block 4. Through the cooperation of the block 12 and the damping spring, the block 12 is engaged with the groove of the block 11, and the hinge can be installed without the help of external tools. The installation operation is quick and convenient.
[0028] In one embodiment, Figure 4 and Figure 5 As shown, the side wall of the clamping block 12 is provided with a chamfer, so that the clamping block 12 is clamped more smoothly.
[0029] In one embodiment, Figure 5 As shown, the disassembly assembly includes a limit plate 13 and a pull rope 14. The side walls of the two first mounting blocks 4 are both provided with a limit plate groove. The inner side walls of the limit plate groove are both slidably connected to the limit plate 13. The side wall of the limit plate 13 located outside the limit plate groove is fixedly connected with a pull ring. The side wall of the limit plate 13 located inside the limit plate groove is fixedly connected with a pull rope 14. The end of the pull rope 14 away from the limit plate 13 extends through the block groove and is fixedly connected to the side wall of the block 12. When the hinge needs to be disassembled and replaced, it is only necessary to pull the pull ring to pull the limit plate 13 out of the limit plate groove and rotate it ninety degrees. At this time, the limit plate 13 can be stuck outside the limit plate groove. The limit plate 13 pulls the pull rope 14, and the pull rope 14 pulls the block 12 into the block groove to release the clamping connection with the groove of the plug block 11. Then the first base 1 and the second base 2 can be disassembled. No external tools are required, and the disassembly operation is quick and convenient.
[0030] In one embodiment, Figure 3 As shown, the limiting plate 13 is a rectangular parallelepiped. Since the limiting plate 13 is a rectangular parallelepiped, it can be stuck outside the limiting plate slot after rotating ninety degrees.
[0031] In one embodiment, Figure 3 and Figure 4 As shown, a lubricating oil hole is provided on the side wall of the second base 2, the lubricating oil hole is connected to the rotating base hole, and a sealing nut 9 is threadedly connected to the lubricating oil hole of the second base 2. The sealing nut 9 is rotated to open the oil inlet hole 10. Example
[0032] In one embodiment, Figure 4 As shown, an arc-shaped sealing strip 8 is arranged in the rotating base hole to prevent the lubricating oil from leaking out.
[0033] In one embodiment, Figure 3 and Figure 4 As shown, lubricating oil is filled in the rotating base hole. The lubricating oil will automatically flow into the rotating base hole, making the rotating base 7 rotate more smoothly and reducing the friction loss of the rotating base 7.
[0034] The above embodiment discloses a hinge for a multi-degree-of-freedom platform. First, the arc-shaped sealing strip 8 is placed in the rotating base holes of the first base 1 and the second base 2, and then the plug block 11 of the second mounting block 5 is inserted into the plug block groove of the first mounting block 4. The clamping block 12 is engaged with the groove of the plug block 11 through the cooperation of the clamping block 12 and the damping spring, and the hinge can be installed without the need for external tools. The installation operation is quick and convenient.
[0035] When the hinge needs to be disassembled and replaced, one only needs to pull the pull ring, pull the limit plate 13 out of the limit plate slot, and rotate it ninety degrees. At this time, the limit plate 13 can be stuck outside the limit plate slot, and the limit plate 13 pulls the pull rope 14, and the pull rope 14 pulls the card block 12 into the card block slot, releasing the card connection with the groove of the plug block 11, and then the first base 1 and the second base 2 can be disassembled without the help of external tools. The disassembly operation is quick and convenient.
[0036] When it is necessary to pour lubricating oil into the rotating base hole, it is only necessary to rotate the sealing nut 9, open the oil inlet hole 10, and then pour the lubricating oil. The lubricating oil will automatically flow into the rotating base hole, making the rotating base 7 rotate more smoothly and reducing the friction loss of the rotating base 7.
[0037] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
