The present invention provides an emergency lighting lamp with a cleaning mechanism, which relates to the technical field of emergency lighting lamps and comprises an emergency lighting lamp box, wherein two lighting lamps are arranged above the emergency lighting lamp box, micro motors are fixedly installed on the backs of the two lighting lamps, a rotating rod is arranged at the end of each micro motor output shaft, and a connecting rod is rotatably installed inside each rotating rod near the end, a cone will toggle a ratchet to rotate once, and when the cone rotates and resets through the ratchet, the cone will retract into a fixed sleeve for a section, so that during normal maintenance, the device will automatically clean, and in an emergency, the cleaning frame will continuously clean the surface of the lighting lamp to prevent smoke from covering the fixed sleeve, and at the same time, each rotation of the cleaning frame will drive the ratchet to rotate one circle, and when the ratchet rotates and falls off the threaded rod, the user needs to replace the cleaning cotton, which plays an automatic reminder role.

The invention discloses a side-opening cabin door adsorption fixing device, application and a working method, solves the problems of low construction efficiency and poor universality of a fixing mode in the production process of a side-opening cabin door in the prior art, and has the beneficial effects of facilitating construction and avoiding the problem of refinishing paint. According to the specific scheme, the side-opening cabin door adsorption fixing device comprises a supporting rod, the supporting rod is sleeved with a connecting pipe in the circumferential direction, the supporting rod can rotate relative to the connecting pipe, the length of the supporting rod is larger than that of the connecting pipe, a magnetic piece is fixedly arranged on the outer side of the connecting pipe and protrudes out of the connecting pipe, and the two ends of the supporting rod are bent; one end of the supporting rod can drive the connecting pipe to extend into the side-opening cabin door lock hole, the size of the magnetic piece is larger than the inner diameter of the side-opening cabin door lock hole, and the part, protruding out of the connecting pipe, of the magnetic piece can be attracted and fixed to the cabin door plate. The end, located on the inner side of the side-opening cabin door, of the supporting rod makes contact with the lock base and provides acting force to avoid free sliding of the side-opening cabin door.

The invention discloses a linear sliding rail and an upper dustproof piece of the linear sliding rail. The upper dustproof piece comprises a connecting section and two floating dustproof sections connected to the two opposite sides of the connecting section respectively. Each floating dustproof section is provided with a bearing strip and at least one rib connected with the bearing strip. Each bearing strip is provided with two end portions, and each end portion is provided with an oblique angle far away from at least one rib. The oblique angles of the four end portions are used for being inserted into four fault-tolerant grooves of two end covers respectively, a fault-tolerant gap is reserved between each end portion and the corresponding end cover, so that the oblique face of each oblique angle can abut against the corresponding fault-tolerant groove, and each end portion can deform towards the fault-tolerant gap. Therefore, through the structural matching of each end part and the corresponding fault-tolerant slot, each end part can be deformed towards the fault-tolerant gap so as to absorb the assembly tolerance.

The utility model relates to the technical field of carbon fiber processing, and discloses a gluing device for carbon fiber prepreg cloth production, which comprises a machine body, the upper side and the lower side of the left end of the machine body are fixedly connected with mounting blocks, the interiors of the mounting blocks are slidably connected with hairbrushes I, and the inner walls of the mounting blocks are fixedly connected with two springs. Limiting blocks are fixedly connected to the close ends of the springs on the upper side and the lower side, extrusion blocks are fixedly connected to the close ends of the limiting blocks on the upper side and the lower side, a tensioning mechanism is arranged on the left side of the interior of the machine body, and a glue dipping box is fixedly connected to the left side of the interior of the machine body; the front side and the rear side of the right end of the gum dipping box are fixedly connected with fixing blocks. According to the dust removal device, through mutual matching use of the spring, the extrusion block and other structures, it is guaranteed that the first brush can keep a certain contact force in the use process, and then the dust removal efficiency of the dust removal device cannot be reduced.
