DETAILED DESCRIPTION

[0020] It should be noted that the terms "first", "second", etc. in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, so that the embodiments of this application described here, based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0021] Reference Figure 1-Figure 3 A joint lubrication device for a prosthesis includes a foot body 9 and two fixing plates 4. Grooves 10 are provided on both sides of the foot body 9. Rotating shafts 11 are rotatably connected in the two grooves 10. The two rotating shafts 11 are fixed to the two fixing plates 4 respectively, so that the fixing plates 4 and the foot body 9 can rotate. A fixing block 7 is welded on one side of the two fixing plates 4 in opposite directions. A mounting port is provided on the upper surface of the fixing block 7. A storage box 6 for placing lubricant is fixed in the mounting port by bolts. A second connecting rod is welded on the bottom of the storage box 6. The connecting pipe 12 is connected to the groove 10, and a blanking assembly for controlling the discharge of the lubricant is provided in the storage box 6. The top of the storage box 6 is clamped with a sealing cover 5, and the outer side of the storage box 6 is provided with an adsorption assembly for fixing the sealing cover 5. The lubricant in the storage box 6 enters the second connecting pipe 12 through the blanking assembly, and then enters the groove 10 through the second connecting pipe 12 to lubricate the rotating shaft 11, which is convenient for the user to lubricate the rotating part of the prosthesis, thereby improving the convenience of using the prosthesis.

[0022] In the present invention, the blanking assembly includes a fixing ring 17, which is welded to a position near the bottom of the storage box 6. Two sliding holes are provided on the upper surface of the fixing ring 17, and a sliding column 16 is slidably connected in the two sliding holes. A slide plate 13 is welded to the bottom of the slide plate 16, which fits the fixing ring 17. A gap is provided between the slide plate 13 and the storage box 6, and a sealing gasket is provided between the slide plate 13 and the fixing ring 17. A stop block 15 is welded to the top of the slide plate 16, and a spring 14 is sleeved on the circumferential outer wall of the slide plate 16, and the two ends of the spring 14 are respectively fixed to the stop block 15 and the fixing ring 17. A pushing assembly for moving the slide plate 13 downward is provided on the outside of the storage box 6. The pushing assembly includes an airbag ball 2, and the airbag ball 2 is provided On one side of the two fixed plates 4, both sides of the airbag ball 2 are adhered with a first connecting tube 1, and the first connecting tube 1 is connected to the storage box 6. When the airbag ball 2 is pressed, the gas in the airbag ball 2 will enter the storage box 6 through the first connecting tube 1. Since the storage box 6 is in a sealed state, the gas entering the storage box 6 will squeeze the lubricant, and the squeezed lubricant will push the slide plate 13 to move downward, and the slide plate 13 will drive the sliding column 16 to move downward, and the sliding column 16 will drive the stop block 15 to move downward and squeeze the spring 14, so that the slide plate 13 is disengaged from the fixed ring 17. At this time, the lubricant in the storage box 6 will flow downward through the gap between the slide plate 13 and the storage box 6 and enter the second connecting tube 12;

[0023] The adsorption component includes two magnetic blocks, which are symmetrically bonded to the outer circumferential wall of the storage box 6 near the top. Two iron blocks are symmetrically welded to the outside of the sealing cover 5, and the two iron blocks are adsorbed on the two magnetic blocks respectively. The sealing cover 5 is fixed by the adsorption between the magnetic blocks and the iron blocks, so as to facilitate the disassembly of the sealing cover 5. At the same time, the suction force between the magnetic blocks and the iron blocks is greater than the pressure generated by the gas in the storage box 6 when the airbag ball 2 is pressed. A strap 3 for connecting the fixing plate 4 to the leg is bonded between the two fixing plates 4 near the top, and two reinforcing plates 8 are welded on the top of the foot body 9. Both reinforcing plates 8 are U-shaped.

[0024] Working principle: When lubrication is needed, press the airbag ball 2, and the gas in the airbag ball 2 will enter the storage box 6 through the first connecting tube 1. Since the storage box 6 is in a sealed state, the gas entering the storage box 6 will squeeze the lubricant, and the squeezed lubricant will push the slide plate 13 to move downward, and the slide plate 13 will drive the slide column 16 to move downward, and the slide column 16 will drive the stop block 15 to move downward and squeeze the spring 14, thereby disengaging the slide plate 13 from the fixing ring 17. At this time, the lubricant in the storage box 6 will flow downward through the gap between the slide plate 13 and the storage box 6, and then enter the groove 10 through the second connecting tube 12 to lubricate the rotating shaft 11, which is convenient for the user to lubricate the rotating part of the prosthesis, thereby improving the convenience of using the prosthesis.
