A gear matching the opening on the sliding sleeve seat and a claw controlled by a torsion spring are installed in the connecting seat through a hinge shaft, and the claw pressed down by the torsion spring matches the gear, and the gear is meshed with the rack.

[0009] Specific processing flow: material preparation → processing technology → assembly → debugging → quality inspection.

[0010] The utility model firstly selects suitable metal materials, such as stainless steel, aluminum alloy, etc., and cuts them into parts of corresponding sizes according to the size requirements of the bellows; gears, semicircular clamps, a section of parallel pull rods with racks, bolts and nuts, U-shaped handles, springs, claws, sliding sleeve seats, and connecting plates.

[0011] Processing technology: The processing of the sliding sleeve seat requires the square sliding sleeve seat to be processed with reserved holes on the upper, left and right sides according to the size of the parallel pull rod and the gear, and the bolt holes are processed on the upper side (ear), inner side and outer side (two) of the sliding sleeve seat respectively. The inner side of the sliding sleeve seat is welded with a connecting plate and the bolt holes are drilled on the connecting plate. U-shaped handle processing: the round stainless steel pipe needs to be processed into a U shape, the connecting plate is welded on the top of the U shape, and the bolt holes are reserved on the inner and outer sides according to the size of the claw and the gear. Parallel pull rod processing: first, a section of the parallel pull rod is provided with a rack (the length is at least 1 / 2), and the inner side of the other end of the parallel pull rod is welded with a connecting plate and the bolt holes are drilled on the connecting plate. Claw processing: the thin steel sheet needs to be processed into a rectangular U-shaped claw, and bolt holes are reserved on both sides. Spring processing: the spring needs to be processed into a shape suitable for the size of the claw. Finally, the parts of the welded and overall completed parts are sprayed to improve the corrosion resistance and aesthetics of the surface.

[0012] Assembly: Step 1: A semicircular card reserved hole and a connection plate reserved hole at the end of the parallel pull rod are assembled at the bolt hole using bolts and nuts (the bolt connection is removable, which is convenient for replacing semicircular card suitable for the size of the bellows). Step 2: Another semicircular card reserved hole and the reserved hole of the connection plate of the sliding sleeve seat are connected by bolts and nuts (the bolt connection is the same as the first step, which is removable and convenient for replacing semicircular card suitable for the size of the bellows). Step 3: A section of parallel pull rod with a rack is inserted and set with the sliding sleeve seat. Step 4: Assemble the claw with the processed spring. Step 5: The reserved hole of the claw and the reserved hole at the upper end of the sliding sleeve seat are connected and assembled by bolts and nuts. Step 6: The gear and the reserved hole of the sliding sleeve seat are connected and assembled by bolts and nuts. Step 6: The top connection plate of the U-shaped handle and the reserved hole of the sliding sleeve seat are connected and assembled by bolts. The processing and assembly of a bellows connection and installation tool can be completed.

[0013] Debugging: Debug the assembled bellows connection installation tool, check the connection parts, and whether the connection tension meets the use requirements to ensure the normal use of the device.

[0014] Quality inspection: Quality inspection of finished products, including size inspection, appearance inspection, functional testing, etc., to ensure that the work meets the requirements of use.

[0015] Specific construction process: prepare the bellows connection installation tools → adjust the gear position → connect the bellows → place the bellows connection part → operate the U-shaped handle → connect the bellows to the best.

[0016] The first step is to prepare the bellows connection installation tool, the second step is to manually press the claw to ensure that the claw does not block the free rotation of the gear (the claw acts through the spring, and the gear rotates toward the middle of the horizontal pull rod to limit the gear rotation effect. On the contrary, manually pressing it without contacting the gear can make the gear rotate freely), adjust the gear to the top of the pull rod (the role is to reserve enough distance to ensure that the bellows reaches the best connection and installation effect), the third step is to prepare the two large and small head bellows to be connected for manual or mechanical preliminary connection, the fourth step is to place one section of the semicircular clamp of the bellows connection installation tool in the concave position of the large head bellows, and the other end of the semicircular clamp is placed in the concave position of the small head bellows, the fifth step is to swing the U-shaped handle manually by one person to make the gear rotate in the middle of the rack near the horizontal pull rod, so that the semicircular clamps on the bellows at both ends have a tensioning force on the inside, so as to achieve the bellows tightening connection effect, and finally, the same operation can be performed by swinging the U-shaped handle back and forth to rotate the gear until the middle rack of the horizontal pull rod ends, so as to achieve the best connection state of the bellows.

[0017] The construction process of the bellows connection and installation tool has improved structure, is simple, can be connected and installed by one person, is easy to operate, is formed in one step, can quickly fix the bellows connection, ensures the firmness of the bellows connection, and is more stable and reliable to install. The construction is safe and reliable, and the installation efficiency is improved. Through the replaceable semicircular clamp, it is suitable for bellows of different specifications and has universality. BRIEF DESCRIPTION OF THE DRAWINGS
