DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0020] See also Figures 1 to 3 An embodiment of the utility model provides an adjustable instrument maintenance mechanism, which includes a fixed cylinder 1, an annular inflated pleated airbag 2, an air injection component 5 and an adjustment component 7.

[0021] In the embodiments of the present invention, please refer to Figures 1 to 3 An adjusting assembly 7 is installed on the fixed cylinder 1, and the adjusting assembly 7 includes a base 71, a sliding rod 72 is fixedly installed on the base 71, and a sliding sleeve 73 is sleeved on the sliding rod 72, a connecting frame 74 is fixedly installed on the sleeve 73, and the connecting frame 74 is fixedly connected to the outer cylinder wall of the fixed cylinder 1, and a fastening screw 75 for fastening the sleeve 73 is threadedly connected to the sleeve 73.

[0022] It should be noted that: the base 71 is fixed on the maintenance table by screws, and then the sleeve 73 is slid up and down along the sliding rod 72 according to the actual needs of the maintenance personnel, and the sleeve 73 is slid to a suitable height and then the fastening screw 75 is screwed, so that the maintenance height of the instrument can be adjusted, thereby avoiding the maintenance personnel being easily tired because the instrument is too high or too low during the inspection and maintenance of the instrument;

[0023] In the present embodiment, both side walls of the sliding rod 72 are fixedly embedded with axially distributed limiting ribs 721, and the two limiting ribs 721 respectively pass through the side grooves formed in the sleeve tube 73 and are slidably connected to the side grooves, thereby improving the stability of the sleeve tube 73 when sliding along the sliding rod 72.

[0024] In the embodiments of the present invention, please refer to Figures 1 to 3 An annular groove 1a is opened in the middle of the inner cylinder wall of the fixed cylinder 1, and the annular groove 1a is installed with an annular inward-expanding corrugated airbag 2, and the outer wall of the annular inward-expanding corrugated airbag 2 is fixedly connected to the inner groove wall of the annular groove 1a; an annular base 11 is fixedly installed on the inner cylinder wall of the fixed cylinder 1 near the bottom, and an annular pressed corrugated airbag 3 is fixedly installed on the annular base 11, and a carrying ring 4 for carrying the instrument base is fixedly installed on the upper bag surface of the annular pressed corrugated airbag 3, and the annular pressed corrugated airbag 3 is connected with the annular inward-expanding corrugated airbag 2 through a plurality of annularly distributed air guide tubes A31.

[0025] It should be noted that: the cylindrical shell of the instrument is inserted into the fixed tube 1, and the supporting ring 4 is driven to press the annular pressed pleated airbag 3 under the action of the instrument's own gravity. Therefore, the annular pressed pleated airbag 3 is compressed and drives the gas in the annular pressed pleated airbag 3 to flow into the annular inflated pleated airbag 2 through the air duct A31. Therefore, the annular inflated pleated airbag 2 expands and extends toward the cylindrical shell, and the expanded and extended annular inflated pleated airbag 2 can quickly perform preliminary clamping on the inserted shell of the instrument.

[0026] In the embodiments of the present invention, please refer to Figures 1 to 3 An annular air storage chamber 1b is provided in the fixed cylinder 1 above the annular inflated corrugated airbag, and the bottom of the annular air storage chamber 1b is communicated with the annular inflated corrugated airbag 2 through a plurality of annularly distributed air guide tubes B6, and an air injection assembly 5 is provided in the fixed cylinder 1, and the air injection assembly 5 includes an annular piston 51, the annular piston 51 is slidably installed in the annular air storage chamber 1b, and a plurality of annularly distributed U-shaped push rods 52 are fixedly installed on the annular piston 51, the U-shaped push rod 52 extends out of the fixed cylinder 1, and a rotating ring 54 is fixedly mounted on the connecting end of the other vertical rod of the U-shaped push rod 52, and a rotatable threaded connection ring 53 is installed at the bottom of the rotating ring 54, and the threaded connection ring 53 is threadedly connected to the external thread 12 provided on the outer cylinder wall of the fixed cylinder 1.

[0027] It should be noted that: when the cylindrical shell of the instrument is stably inserted into the fixed tube 1, the instrument is kept above the fixed tube 1, and the threaded connecting ring 53 is rotated so that the threaded connecting ring 53 is screwed downward along the external thread 12, so that the U-shaped push rod 52 pushes the annular piston 51 to slide down, so that the gas in the annular air storage chamber 1b enters the annular inflated corrugated airbag 2 through the air guide tube B6, so that the annular inflated corrugated airbag 2 further expands. Therefore, the expanded and extended annular inflated corrugated airbag 2 can avoid the hidden danger of clamping the shell of the instrument when clamping it. On the other hand, it can weaken the internal stress between the instrument and the clamping device caused by the vibration generated by the maintenance of the instrument.

[0028] The working principle of the adjustable instrument maintenance mechanism provided by the utility model is as follows:

[0029] The sleeve tube 73 is slid up and down along the sliding rod 72 according to the actual needs of the maintenance personnel. After the sleeve tube 73 slides to the appropriate height, the fastening screw 75 is tightened to adjust the maintenance height of the instrument, thereby avoiding the maintenance personnel from getting tired due to the instrument being too high or too low during the inspection and maintenance of the instrument. The cylindrical shell of the instrument is inserted into the fixed tube 1, and the load-bearing ring 4 is driven to press the annular pressed pleated airbag 3 under the action of the instrument's own gravity. Therefore, the annular pressed pleated airbag 3 is compressed and the gas in the annular pressed pleated airbag 3 is driven to flow through the air guide pipe A31 to the annular inflated pleated airbag 2. Therefore, the annular inflated pleated airbag 2 expands and extends to the cylindrical shell, and the expansion The extended annular inward-inflating corrugated airbag 2 can quickly perform preliminary clamping on the shell of the instrument. When the cylindrical shell of the instrument is stably inserted into the fixed tube 1, the threaded connecting ring 53 is rotated to make the threaded connecting ring 53 screw downward along the external thread 12, so that the U-shaped push rod 52 pushes the annular piston 51 to slide down, so that the gas in the annular air storage chamber 1b enters the annular inward-inflating corrugated airbag 2 through the air guide tube B6, so that the annular inward-inflating corrugated airbag 2 further expands. Therefore, the expanded and extended annular inward-inflating corrugated airbag 2 can avoid the hidden danger of clamping damage to the shell of the instrument when clamping it. On the other hand, it can weaken the internal stress between the instrument and the clamping device caused by the vibration generated by the maintenance of the instrument.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
