The utility model discloses a bicycle parking frame, and one side of the interior of a mounting L-shaped plate is rotatably connected with a telescopic supporting rod, and the other side of the interior of the mounting L-shaped plate is rotatably connected with a deflection supporting rod. Through a first limiting arc groove in the mounting L-shaped plate, the telescopic supporting rod can conveniently drive a first supporting wheel to deflect; a telescopic supporting rod is locked and limited through a locking rotary knob, so that the wheel is preliminarily supported, a deflection supporting rod conveniently drives a second supporting wheel to deflect through a second limiting arc groove in a mounting L-shaped plate, and under the supporting effect of a supporting torsional spring, the deflection supporting rod is preliminarily supported and limited conveniently; the first supporting wheel and the second supporting wheel are rotated to be attached to the edge of the bicycle wheel, so that the bicycle wheel is effectively supported, and the stability of the parking frame in the actual bicycle supporting process is ensured.

This invention relates to the field of tank processing technology, and discloses a tank bottom assembly, a tank, and a method for forming the tank bottom assembly. The tank bottom assembly includes a tank bottom and a transition ring. The transition ring is located at the open end of the tank bottom and is integrally formed with the tank bottom. The outer wall of the transition ring has a first step surface and a second step surface that are vertically arranged. The first step surface is arranged radially along the transition ring, and the outer edge of the second step surface away from the first step surface is inclined towards the outer wall of the tank bottom to form a guide slope. The tank includes a cylindrical section and the aforementioned tank bottom assembly. The method for forming the tank bottom assembly includes the following steps: fixing the outer ring of a constraint plate, and shearing and spinning the plate using a spinning wheel to obtain a first formed part; releasing the outer ring constraint and fixing the inner ring constraint, and flanging and spinning the outer ring using a spinning wheel to form a column section; machining a mating interface on the outer wall of the column section to obtain an integrally formed tank bottom and transition ring. The tank has better quality and lower processing costs.

The utility model discloses a liquid level measuring device for a reverse drainage tank of a coal seam drainage and production well, which relates to the technical field of coal seam gas development and comprises the reverse drainage tank, a measuring component is arranged on one side of the reverse drainage tank in a matched mode, and the measuring component comprises a first support, a support frame and a second support which are fixedly connected. The bottom end of the supporting frame is fixedly connected with a guiding base and a limiting cylinder. The measuring assembly further comprises an outer connecting frame, an upper positioning cover and a lower positioning cover which are sequentially connected from top to bottom. The effect of conveniently supporting the whole measuring assembly at the top of the reverse discharge tank is achieved through a first support and a second support, the effect of conveniently supporting and limiting pulleys is achieved through a supporting frame and a guide base at the bottom, and meanwhile the pulleys can be conveniently and horizontally moved and adjusted at the top of the reverse discharge tank; and an open groove is formed in one end of the supporting frame, so that the whole outer connecting frame can slide horizontally along the open groove conveniently, and the effect of winding and unwinding the connecting line between the lead block and the floating ball is achieved through the pulley.

The feeding device comprises two bases, two supporting sleeves, two supporting plates, two supporting bases, two sliding bases, two inserting plates and two sliding plates, the supporting sleeves are fixedly connected to the top of the base located on the right side, the top of the base located on the left side is rotationally connected with the bottom of a feeding machine, and the supporting plates are slidably connected to the inner walls of the supporting sleeves; according to the feeding machine, the supporting plate is fixed or unlocked through a simple structure, the feeding machine is conveniently supported through matching of the supporting plate and the sliding seats, the height of the feeding machine is adjusted, and meanwhile, the feeding machine is convenient to move, convenient to use and high in practicability. And the feeding machine can be conveniently supported and fixed, so that the feeding machine is kept stable during use, and good practicability is achieved.

This application relates to a pipe vibration damping installation structure, specifically within the technical field of pipe connection structures. It includes a pipe and a first damping tube, with both ends of the first damping tube connected to the pipe. Connecting frames are fixed to the pipes on both sides of the first damping tube, and these connecting frames are hinged together via pivots. When the subway travels through the transfer level, the vibrations generated are transmitted to the pipe, causing it to vibrate. This design ensures that the pipes on both sides of the first damping tube can only swing relative to each other around the axis of the pivot, preventing uncontrolled vibrations. Thus, while ensuring the first damping tube effectively dampens vibrations, the design limits the amplitude of pipe swing to a certain extent, preventing damage such as pipe rupture or breakage caused by prolonged vibration or excessive vibration intensity.
