The utility model belongs to the technical field of air springs, and particularly relates to an air spring structure with an adjustable installation position, which comprises an installation slide rail, the top end of the installation slide rail is in sliding connection with an installation seat, the inner wall of the installation seat is provided with a screw rod, and the outer wall of the screw rod is in threaded connection with a threaded slide block. A threaded sliding block is arranged on the mounting base, supporting rods are rotationally connected to the two ends of the threaded sliding block, a telescopic plate is rotationally connected to one end of each supporting rod, a limiting rod is fixedly connected to the inner wall of each telescopic plate, and a positioning base is fixedly connected to the bottom end of each telescopic plate. Then, a threaded sliding block drives a telescopic plate to slide along the outer wall of a limiting rod through a supporting rod, the telescopic plate slides to drive a positioning seat to slide in a limiting groove, the stability of the positioning seat is improved, the positioning seat slides to drive a positioning block to be embedded into a positioning hole, fixing operation of the mounting seat is achieved, and deviation of the mounting seat after adjustment is avoided.

The utility model discloses an anti-explosion positive pressure room, which belongs to the technical field of anti-explosion equipment and comprises a positive pressure room body, a fire exit door is rotatably connected onto the side wall of the positive pressure room body, an anti-explosion window is fixedly connected onto the fire exit door, and an anti-explosion air feeder is fixedly connected above the positive pressure room body. When the inside and outside conditions of the positive pressure room body need to be observed through the explosion-proof window, a pull column is pulled towards the periphery of an external box, the pull column moves to drive a moving plate to move, the moving plate moves to drive a connecting spring to be compressed and a bearing rod to move away from a mounting box, and then a handle is held by a hand to apply force to drive a mounting rod to move. The mounting rod moves to drive the cleaning cotton cloth to move away from the mounting box, when the cleaning cotton cloth moves to pass through the explosion-proof window, the surface of the explosion-proof window can be cleaned, the cleanliness of the surface of the explosion-proof window is guaranteed, and then an operator can conveniently observe the inside and outside conditions of the positive pressure room through the explosion-proof window.

The application relates to the technical field of hydrological drilling equipment, and particularly relates to a hydrological drilling anti-abrasion device, which comprises a probe rod, a drill bit is fixedly installed at the bottom of the probe rod, a threaded block is fixedly connected to the top of the probe rod, and a top block is fixedly connected to the top of the threaded block. The threaded block, a threaded sleeve, a round rod and a round hole are arranged. When the anti-abrasion shell is installed, the anti-abrasion shell is first sleeved outside the probe rod, the threaded sleeve arranged at the top of the anti-abrasion shell is threadedly connected outside the threaded block at the top of the probe rod, meanwhile, the sleeve ring at the top of the threaded sleeve is located outside the top block at the top of the threaded block, at this time, the multiple round rods outside the top block are extended into the round holes on the sleeve ring under the elastic force of the corresponding springs, the insertion is completed, the insertion of the round rod and the round hole and the thread connection between the threaded block and the threaded sleeve are matched, multiple fixing measures are realized, and the fixing effect is better and more firm compared with single thread installation.
