[0016] The working principle and beneficial effects of the present invention are: 1. The present invention is provided with a convenient adjustment mechanism, so that when the height of the first clamp needs to be adjusted, the anti-sliding block can be used to drive the rotating shaft to rotate. The rotation of the rotating shaft will drive the threaded column to rotate through the cooperation of components such as bevel gear B, bevel gear A, rotating rod, and rotating block. When the threaded column rotates, the threaded column will rotate and move upward or downward through the cooperation between the threads of the threaded barrel, thereby realizing the adjustment of the height of the first clamp.

[0017] 2. The present invention is provided with a uniform lubrication mechanism, so that when the threaded column and the threaded barrel are used for a long time and dust is stuck in them, resulting in a large rotation resistance, the threaded column can be adjusted to the bottom, and then appropriate lubricating oil is added to the lubricating oil barrel. At this time, the anti-sliding block rotates the rotating shaft to drive the first clamp to move upward, and the liquid suction pipe assembly absorbs the lubricating oil in the lubricating oil barrel and discharges it into the threaded barrel through the liquid outlet pipe through the cooperation of the rotating gear, gear rod, pressure cylinder and other components, and the lubricating oil is evenly applied between the threaded column and the threaded barrel for lubrication through the rotating and gradually rising threaded column.

[0018] 3. The present invention is provided with a stirring mechanism, so that when the piston rod A in the pressure cylinder moves up and down repeatedly, the stirring rod is driven to rotate back and forth through the cooperation of the hydraulic chamber, the gear rod B, the driven gear and other components. The back and forth rotation of the stirring rod drives the stirring blades to stir the lubricating oil in the lubricating oil cylinder, so that the lubricating oil in the lubricating oil cylinder is stirred evenly, preventing the lubricating oil in the lubricating oil cylinder from sedimentation.

A slider 78 is fixedly connected to the side of the rotating block 77. Two groups of sliders 78 and slide grooves 74 are provided, and the two groups of sliders 78 are slidably connected to the two groups of slide grooves 74 respectively. When the rotating block 77 is rotated, the threaded column 72 is driven to rotate through the cooperation of the two groups of sliders 78 and the two groups of slide grooves 74. A bevel gear A79 is fixedly connected to the top of the rotating rod 76. A rotating shaft 710 is penetrated and rotatably connected to the side of the threaded cylinder 71. A bevel gear B711 is fixedly connected to the side of the rotating shaft 710. The bevel gear A79 is vertically meshed with the bevel gear B711. An anti-sliding block 712 is fixedly connected to the end of the rotating shaft 710 away from the bevel gear B711. When the bevel gear B711 rotates, the bevel gear A79 is driven to rotate. The rotating shaft 710 can be manually driven to rotate through the anti-sliding block 712. A uniform lubrication mechanism 8 is provided on the side of the threaded cylinder 71.

[0026] In this embodiment, the whole device is installed by the mounting plate 1, and the pipe to be fixed is passed through between the first clamp 2 and the second clamp 3, and the two sets of bidirectional threaded rods 4 are rotated at the same time. The rotation of the bidirectional threaded rods 4 causes the first clamp 2 and the second clamp 3 to move closer to each other to clamp the pipe, and the rubber pad 6 between the first clamp 2 and the second clamp 3 can ensure that the pipe is clamped tightly. When the height needs to be adjusted, the rotating shaft 710 is rotated by the anti-sliding block 712, and the rotation of the rotating shaft 710 drives the bevel gear B711 to rotate, and the rotation of the bevel gear B711 drives the bevel gear A79 to rotate, and the rotation of the bevel gear A79 drives the rotating rod 76. The rotation of the rotating rod 76 drives the rotating block 77 to rotate.

The overall adjustment is convenient and easy to install.

[0027] Example 2 Reference Figures 1 to 8, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the uniform lubrication mechanism 8 includes a pressure cylinder 81, a lubricating oil cylinder 87 and a rotating gear 88. The pressure cylinder 81 and the lubricating oil cylinder 87 are both fixedly connected to the side of the threaded cylinder 71. The two sides of the pressure cylinder 81 are respectively penetrated and fixedly connected with a suction pipe 82 and a liquid outlet pipe 83. The insides of the suction pipe 82 and the liquid outlet pipe 83 are both provided with a one-way valve. The end of the suction pipe 82 away from the pressure cylinder 81 penetrates and is fixedly connected to the lubricating oil cylinder 87, and the end of the liquid outlet pipe 83 away from the pressure cylinder 81 penetrates and is fixedly connected to the threaded cylinder 71. The one-way valve in the suction pipe 82 is one-way to the inner direction of the pressure cylinder 81, and the one-way valve in the liquid outlet pipe 83 is one-way to the inner direction of the threaded cylinder 71. When negative pressure is formed in the pressure cylinder 81, the lubricating oil in the lubricating oil cylinder 87 is sucked into the pressure cylinder 81 through the suction pipe 82, and when the pressure cylinder 81 is squeezed, the lubricating oil in the lubricating oil cylinder 87 is discharged into the threaded cylinder 71 through the liquid outlet pipe 83. A return spring 84 is arranged inside the pressure cylinder 81. The piston inside the pressure cylinder 81 is slidably connected with a piston rod A85 through the return spring 84 piston. The top of the piston rod A85 is fixed. A gear rod A86 is connected, and a rotating gear 88 is fixedly connected to the surface of the rotating shaft 710. The teeth on the rotating gear 88 are matched with the teeth on the gear rod A86, and the rotating gear 88 is an incomplete gear. At the beginning, the rotation of the rotating gear 88 will drive the gear rod A86 to move upward. A stirring mechanism 9 is arranged inside the lubricating oil cylinder 87. The stirring mechanism 9 includes a stirring rod 91 and a hydraulic chamber 94. The stirring rod 91 passes through and is rotatably connected to the top of the lubricating oil cylinder 87. A stirring blade 92 is fixedly connected to the side of the stirring rod 91. A driven gear 93 is fixedly connected to the top of the stirring rod 91. The hydraulic chamber 94 4 penetrates through and is fixedly connected to the bottom of the pressure cylinder 81. A piston rod B95 is slidably connected to the internal piston of one end of the hydraulic chamber 94. A piston rod C96 is slidably connected to the internal piston of the other end of the hydraulic chamber 94. A gear rod B97 is fixedly connected to the end of the piston rod C96 away from the hydraulic chamber 94. The top of the piston rod B95 is fixedly connected to the bottom of the piston rod A85. The teeth on the gear rod B97 mesh with the teeth on the driven gear 93. When the piston rod A85 moves upward, it will drive the piston rod B95 to move upward. When the gear rod B97 moves, it will drive the driven gear 93 to rotate through the cooperation between the teeth.

[0028] Compared with Example 1, further, when the threaded column 72 and the threaded barrel 71 are stuck with dust due to long-term use, resulting in a large rotation resistance, the threaded column 72 can be adjusted to the bottom end, and then appropriate lubricating oil is added to the lubricating oil barrel 87. At this time, the rotating block 77 is rotated clockwise to drive the rotating shaft 710 to rotate, so that the threaded column 72 gradually rises. The rotation of the rotating shaft 710 will also drive the rotating gear 88 to rotate. When the rotating gear 88 rotates and its upper teeth are engaged with the upper teeth of the gear rod A86, it will drive the gear rod A86 and the piston rod A85 to move upward, the return spring 84 is stretched, and the upward movement of the piston rod A85 will cause negative pressure to be formed in the pressure cylinder 81, thereby sucking the lubricating oil in the lubricating oil barrel 87 into the pressure cylinder 81 through the suction tube 82, and when the rotating gear 88 rotates to the toothless part to disengage from the gear rod A86, the return spring 84 rebounds and drives the piston rod A85 and the gear rod A86 to move downward When the piston rod A85 moves, the pressure cylinder 81 will be squeezed to discharge the lubricating oil therein into the threaded cylinder 71 through the liquid outlet pipe 83. At this time, the lubricating oil is evenly applied between the threaded cylinder 72 and the threaded cylinder 71 for lubrication through the rotating and gradually rising threaded column 72. The piston rod A85 will also drive the piston rod B95 to move up and down during the up and down movement. The up and down movement of the piston rod B95 will drive the piston rod C96 to move horizontally repeatedly through the hydraulic pressure in the hydraulic chamber 94. The repeated horizontal movement of the piston rod C96 will drive the gear rod B97 to move horizontally repeatedly. The repeated horizontal movement of the gear rod B97 will drive the driven gear 93 to rotate repeatedly through the cooperation between the teeth. The repeated rotation of the gear rod B97 will drive the stirring rod 91 to rotate repeatedly. The repeated rotation of the stirring rod 91 will drive the stirring blade 92 to rotate repeatedly to stir the lubricating oil in the lubricating oil cylinder 87 evenly to prevent the lubricating oil in the lubricating oil cylinder 87 from sedimentation.

[0029] A method for using an adjustable clamp device comprises the following steps: S1. Install the whole device through the mounting plate 1, and rotate the two sets of bidirectional threaded rods 4 at the same time to make the first clamp 2 and the second clamp 3 move closer to each other to clamp the pipe, rotate the rotating shaft 710 through the anti-sliding block 712, and drive the threaded column 72 to rotate through the bevel gear B711, bevel gear A79 and other components. At this time, the threaded column 72 will move up or down under the cooperation of the thread, so as to adjust the overall height of the first clamp 2 and the second clamp 3; S2. When the threaded column 72 and the threaded barrel 71 are stuck with dust due to long-term use, resulting in a large rotation resistance, the threaded column 72 can be adjusted to the bottom, and then appropriate lubricating oil is added to the lubricating oil barrel 87, and the rotating block 77 is rotated clockwise to drive the rotating shaft 710 to rotate so that the threaded column 72 gradually rises. At this time, the liquid suction tube 82 absorbs the lubricating oil and discharges it into the threaded barrel 71 through the liquid outlet pipe 83 through the cooperation of the rotating gear 88, the gear rod A86, the pressure barrel 81 and other components. At this time, the lubricating oil is evenly applied between the threaded column 72 and the threaded barrel 71 for lubrication by the rotating and gradually rising threaded column 72; S3, the piston rod A85 will also drive the piston rod B95 to move up and down in the process of cooperating with the pressure cylinder 81 to transport the lubricating oil. The hydraulic pressure in the hydraulic chamber 94 drives the piston rod C96 to move horizontally repeatedly. At this time, the stirring rod 91 is driven to rotate repeatedly through the cooperation of the gear rod B97 and the driven gear 93, so that the stirring blade 92 stirs the lubricating oil in the lubricating oil cylinder 87 evenly.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.

The rotating shaft (710) is rotated by means of the anti-sliding block (712), and the threaded column (72) is driven to rotate by means of the bevel gear B (711), the bevel gear A (79) and other components. At this time, the threaded column (72) moves upward or downward under the cooperation of the threads, thereby adjusting the overall height of the first clamp (2) and the second clamp (3); S2. When the threaded column (72) and the threaded barrel (71) are stuck with dust due to long-term use, resulting in a large rotation resistance, the threaded column (72) can be adjusted to the bottom, and then appropriate lubricating oil is added to the lubricating oil barrel (87). The rotating block (77) is rotated clockwise to drive the rotating shaft (710) to rotate so that the threaded column (72) gradually rises. At this time, the liquid suction tube (82) absorbs the lubricating oil and discharges it into the threaded barrel (71) through the liquid outlet tube (83) through the cooperation of the rotating gear (88), the gear rod A (86), the pressure barrel (81) and other components. At this time, the lubricating oil is evenly applied between the threaded column (72) and the threaded barrel (71) for lubrication by the rotating and gradually rising threaded column (72); S3. When the piston rod A (85) moves up and down to cooperate with the pressure cylinder (81) to transport the lubricating oil, it also drives the piston rod B (95) to move up and down. The hydraulic pressure in the hydraulic chamber (94) drives the piston rod C (96) to move horizontally repeatedly. At this time, the stirring rod (91) is driven to rotate repeatedly through the cooperation of the gear rod B (97) and the driven gear (93), so that the stirring blade (92) stirs the lubricating oil in the lubricating oil cylinder (87) evenly.
