[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Reference Figure 1-Figure 3 When the lever 2 is pulled back, the lever 2 is in a position to move upwards, and the lever 2 is in a position to move along the cam 4 so that the lever 2 can be moved along the cam 4. When the lever 2 is pulled back, the lever 2 is in a position to move upwards, and the lever 2 is in a position to move along the cam 4.
[0030] Reference Figure 1-Figure 2 A rubber plug 11 is inserted at the top of the connecting pipe 1. The rubber plug 11 is made of rubber material and can block the top of the oil inlet channel 12 to prevent the lubricating oil from leaking. The inner wall of the connecting pipe 1 is provided with an oil inlet channel 12, which can allow the oil inlet channel 12 to transport the lubricating oil to the lubricating cotton 13, so as to facilitate the subsequent lubrication of the bearing by the lubricating cotton 13. The inner wall of the connecting pipe 1 is provided with lubricating cotton 13, which is made of polytetrafluoroethylene material, a low-friction, wear-resistant polymer, which can maintain good performance during long-term use, reduce wear and extend the life of parts.
[0031] Reference Figure 1-Figure 3 The connecting mechanism includes a swivel 9, which is rotatably connected to the inner wall of the connecting pipe 1. The swivel 9 is a prior art and is mainly connected to the connecting pipe 1 through the swivel 9, so that the entire lifting ring 10 and the swivel 9 can adapt to rotation during use. A lifting ring 10 is provided at the top of the swivel 9, and the lifting ring 10 can be connected to an existing hook to connect the goods for subsequent lifting.
[0032] Reference Figure 2 The lubricating cotton 13 contacts the outer wall of the lower end of the swivel 9, and the lower end of the swivel 9 is an existing device bearing, which can lubricate the bearing.
[0033] Reference Figure 1-Figure 3 The inner wall of the left end of the plug block 2 is fixedly connected to one end of the return spring 3. When the connecting plate 4 moves to the left, the return spring 3 will be compressed. When resetting, the elastic force of the return spring 3 is used to return the connecting plate 4. The other end of the return spring 3 is fixedly connected to the outer wall of the connecting plate 4. The connecting plate 4 is slidably connected to the inner walls of the plug block 2 and the connecting tube 1 respectively. The connecting tube 1 is provided with a notch corresponding to the connecting plate 4, so that the connecting plate 4 can slide along the notch. The pressing tube 6 is slidably connected to the inner wall of the connecting tube 1. The wedge block 5 passes through and is slidably connected to the inner wall of the plug block 2. The wedge block 5 is plugged into the inner wall of the limiting groove 8, and the plug block 2 is plugged into the inner wall of the mounting seat 7. The plug block 2 matches the inner wall of the mounting seat 7, and the above materials are all made of high-quality steel materials with high strength.
[0034] Working principle: When the entire connecting pipe 1 is needed, it is only necessary to preliminarily plug the plug block 2 into the mounting seat 7, let the top of the mounting seat 7 squeeze the inclined surface of the wedge block 5, let the wedge block 5 move the connecting plate 4 and the pressing tube 6 to the left and compress the reset spring 3. When the notch of the wedge block 5 and the limiting groove 8 coincide, use the reverse elastic force of the reset spring 3 to reset the connecting plate 4, the wedge block 5 and the pressing tube 6 to the right, let the wedge block 5 be plugged into the inner wall of the limiting groove 8, and complete the installation of the entire connecting pipe 1 and the mounting seat 7.
[0035] When the connecting tube 1 needs to be disassembled after use, just touch and press the pressing tube 6 with the index fingers of both hands to separate the pressing tube 6 with the connecting plate 4 and the wedge block 5 from the inner wall of the limiting groove 8, and then move the entire plug block 2 out from the inner wall of the mounting seat 7 to complete the entire disassembly and assembly steps.
[0036] When the lower end bearing of the swivel 9 needs lubrication, it is only necessary to separate the rubber plug 11 from the top end of the connecting tube 1, and then pour the lubricating oil from the opening of the connecting tube 1, so that the lubricating oil enters the lubricating cotton 13 along the oil inlet channel 12 and is absorbed by the lubricating cotton 13. During the rotation of the swivel 9, it will come into contact and squeeze with the lubricating cotton 13, so that the lubricating cotton 13 squeezes out the lubricating oil to lubricate the lower end bearing of the swivel 9, and finally the rubber plug 11 is connected to the top end of the connecting tube 1, and the lubricating oil can be regularly injected into the lubricating cotton 13 for storage and lubrication.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
