The utility model discloses a luggage rack tolerance regulator, the upper portion inboard of cylinder is provided with annular boss, positioning sleeve tight cooperation fixed sleeve is located cylinder outside, is provided with the limit dog of the L shape that stretches upwards respectively in the lower part of positioning sleeve's left and right sides, is provided with the matched support on the upper portion of positioning sleeve, and this matched support is located respectively in the front and back sides of limit dog, is provided with the limit board that stretches outward respectively on this matched support, is provided with internal thread on the inboard wall of cylinder, the adjusting screw rod is through the screw rotation and is located on the internal thread of cylinder, is provided with annular limit seat on the bottom of adjusting screw rod, is seted up in the adjusting through -hole of adjusting screw rod, is provided with the snap spring in this adjusting through -hole, the utility model has the advantages of: not needing special fixed torque electric spanner, also can complete the installation of this tolerance regulator, and assembly is more convenient and fast, and need not be restricted by tool again.

The tension spring type key module comprises a base, a tension spring, an upper cover, a key assembly and a trigger assembly, the base is matched with the upper cover to form a working bin with an opening in the top, the key assembly is installed in the working bin, and a part of the key assembly upwards extends out of the working bin from the opening. The key assembly has a free stroke in the vertical direction in the working bin, and the key assembly is matched with the working bin through at least one tension spring to realize elastic reset of the free stroke; the upper end of the tension spring is fixed in the working bin, the lower end of the tension spring is fixed on the key assembly, and when the key assembly moves downwards, the tension spring is pulled, and the key assembly pushes the trigger assembly to complete contact of contacts in the trigger assembly. The tension spring is adopted to replace a pressure spring, so that noise generated during key operation can be remarkably reduced. The structural change of the tension spring is different from that of the pressure spring when the tension spring bears force, so that noise is reduced, and more silent use experience is provided.

This utility model relates to the field of mechanical engineering technology and discloses a damper that can be disassembled and maintained on-site. It includes a lower section tube, with a splitting mechanism installed at the top of the lower section tube. The splitting mechanism facilitates the disassembly and assembly of the equipment. A limiting mechanism is installed on the outer wall of the splitting mechanism to limit the range of motion of the equipment and prevent overuse. The splitting mechanism includes a housing, which is installed on the top left and right sides of the lower section tube. A rotating shaft is fixedly connected to the upper part of the inner wall of the housing, and a hinged plate is rotatably connected to the outer wall of the rotating shaft. A telescopic push rod is fixedly connected to the lower part of the inner wall of the housing. In this utility model, the upper and lower sections are first aligned, then the housing is inserted into the mating groove, and the hinged plate is engaged with the groove, thus fixing the upper and lower sections together. Finally, a button is pressed to loosen the connection, allowing the lower section tube to be removed, completing the disassembly of the equipment for easy on-site maintenance.

The present invention belongs to the technical field of chain link fence machines, and particularly relates to a single-needle chain link fence machine, comprising a base frame, a driving mechanism, a main transmission mechanism, a netting mechanism and a flap mechanism, wherein the netting mechanism is slidably connected to the base frame and can make reciprocating motion relative to the base frame; the netting mechanism comprises a netting machine frame, a plurality of positioning needles, a rotating shaft, and a first auxiliary transmission mechanism, wherein the plurality of positioning needles are fixed to a fixed rod, and the fixed rod is fixed to the netting machine frame, and each positioning needle is respectively connected to the rotating shaft via a rope, and the rotating shaft is rotatably connected to the netting machine frame, and the rotating shaft is connected to the driving mechanism via the first auxiliary transmission mechanism to drive the rotating shaft to rotate. The present invention changes the original "collision type" transmission of the positioning needle into a rope transmission, which reduces noise, can protect components to a great extent, and increase their service life, and the use of rope transmission also greatly improves the rebound speed of the positioning needle, so that one positioning needle can be used instead of the original two positioning needles.
