The invention provides an isolating switch limiting interlocking structure which comprises an isolating switch body, the isolating switch body comprises a supporting bracket, a control box and a vertical connecting rod, the isolating switch body further comprises a transmission limiting mechanism, the top of the control box protrudes upwards to form a limiting block, and the limiting block is provided with a closing end and an opening end; and the transmission limiting mechanism comprises a transmission part and a limiting part, the transmission part is arranged above the limiting block, the bottom of the transmission part is connected with the output end of the control box, the top of the transmission part is connected with the vertical connecting rod, the transmission part is provided with a limiting opening, and the limiting part is rotatably connected in the limiting opening. In this way, when the limiting part is manually rotated to be clamped in the limiting clamping groove, limiting can be carried out in the switching-on / switching-off state; and when the limiting part is rotated to the position above the limiting clamping groove, the limiting part can be separated to perform state switching, so that the whole manual operation switching is relatively convenient, the structure is limited in place, and a relatively good opening and closing effect can be ensured.

The utility model discloses a faucet water purifier which comprises a waterway switching assembly and a filtering assembly, the filtering assembly comprises a shell with a filtering cavity and a filter element arranged in the filtering cavity, the top of the shell is provided with an exhaust hole used for exhausting gas in the filtering cavity, and the shell is further provided with a floating ball valve located in the filtering cavity. And when the water level in the filtering cavity reaches the highest water level, the ball float valve closes the exhaust hole under the action of buoyancy. The exhaust hole is formed in the top of the shell of the filtering assembly, and the floating ball valve is arranged in the filtering cavity, so that when the water level in the filtering cavity does not reach the highest water level, the floating ball valve is in a state of opening the exhaust hole, and gas above the liquid level is prevented from being compressed under the action of continuously rising liquid level pressure; therefore, when the filter assembly does not discharge purified water, the compressed gas above the liquid level of the filter cavity is prevented from extruding residual liquid in the filter cavity out of the filter cavity, water leakage of a water outlet below the filter assembly is prevented, and the use experience of a user is good.

The invention relates to a device for remotely controlling the pressure of a pinch roll, which belongs to the technical field of hot galvanizing production lines, and comprises a pressure device for remotely controlling the pressure of the pinch roll, the pressure device comprises a three-way pipe, a normally closed manual valve, a regulating valve, a speed regulating valve, a normally open manual valve and a proportional valve; the number of the three-way pipes is two, the separated ends of the two three-way pipes are provided with an air inlet connector and an air outlet connector respectively, the three-way pipes, the normally-closed manual valve, the adjusting valve, the speed adjusting valve, the normally-open manual valve and the proportional valve are connected through pipelines, elbows are connected between the normally-open manual valve and the proportional valve and between the proportional valve and the three-way pipe on the right side, and the speed adjusting valve and the speed adjusting valve are connected through pipelines. The connector is used for connecting straight pipes. According to the device for remotely controlling the pressure of the pinch roll, a set of light and practical pressure adjusting device is designed according to the production requirement and the limited field operation space aiming at the problem of misalignment or deviation of belt tail coiling caused by mismatching of the pressure of the pinch roll, and the pressure of the pinch roll can be simply, safely, efficiently and accurately adjusted.

The utility model relates to the technical field of shutter, disclose convenient to clean's building aluminium alloy shutter, including two protective housing, each protective housing inside all rotatoryly connected with a plurality of limit strip, a plurality of louver board are arranged between both sides protective housing, the louver board and both sides limit strip between interlock, the louver board outer wall is provided with cleaning assembly and rotating assembly, the cleaning assembly includes a plurality of sliding blocks, the sliding block is located the outer wall of louver board, the sliding block outer wall fixed connection is in a plurality of both sides of protective housing, the both sides of protective housing all are provided with connecting plate, the sliding block sliding connection is in the inside of connecting plate. In the utility model, through moving both sides protective housing, makes limit strip separate from both sides of louver board, realizes the disassembly of louver board, and utilizes the interlock between the sliding block inside and card block, fixes the position of protective housing, reaches the effect that the surface of louver board is conveniently cleaned, and the portability of louver board surface cleaning is strengthened.

The high-strength anti-explosion civil air defense door comprises a door frame, a hinge support and a door body, a first groove is formed in the bottom side of the door body, a clamping rod is fixedly connected in the first groove, a first clamping sleeve is connected to the clamping rod in a sleeved mode, a second clamping sleeve is connected to the bottom side of the first clamping sleeve in a sleeved mode, and a connecting frame is fixedly connected to the bottom end of the second clamping sleeve. A connecting frame is arranged on the bottom side of the door body, a supporting wheel is rotationally connected into the connecting frame through a rotating shaft, recesses are formed in the two sides of the supporting wheel, a limiting rod is fixedly connected to the upper end of the connecting frame, a spring is connected to the limiting rod in a sleeved mode, a protrusion is connected to the limiting rod in a sleeved mode, and the protrusion is fixedly connected to the bottom side of the first clamping sleeve.
