The invention belongs to the technical field of railway vehicle couplers, and particularly relates to a car coupler and a locking method thereof. The car coupler comprises a coupler head provided with a sliding piece, and a fixing device installed on the end wall of the vehicle body; a guide sliding rail is formed on the edge of one side of the fixing device, and a locking block is arranged on the fixing device; and a locking device is further arranged on the coupler head, under driving of external force, the sliding piece on the coupler head moves towards the locking block along the guide sliding rail till the locking device is matched with the locking block, and locking of the coupler is achieved. With the car coupler, a folding locking, unlocking, or straightening locking process can be achieved by one hand, excessive manual intervention is not needed, the action track is clear and definite, and operation is convenient, efficient and automatic.

The invention relates to the technical field of medical instruments, and concretely relates to a foot-operated cart for carrying a cleaning frame of a medical cleaning machine. The cart comprises a frame, a tank body is formed in the top of the frame, the left side, the right side and the rear end of the tank body are each provided with a blocking wall, a protruding part is arranged at the front end of the tank body, guide damping pieces are symmetrically arranged on the two sides of the protruding part, a pedal is arranged at the bottom of the rear end of the frame, a cart coupler lock and arotating shaft are arranged at the front end of the frame, one end of the rotating shaft is in shaft connection with the frame, and the other end of the rotating shaft is connected with the pedal through a transmission assembly. Only the cart coupler lock needs to be butted with a shackle to make the shackle hooked by the cart coupler lock, so the cart can be stably connected with the cleaning machine, the cleaning frame can be stably and accurately pushed into a cabin, meanwhile, the cart and the cleaning machine can be disconnected only by treading the pedal downwards, and the carrying convenience of the cleaning frame in the using process of the medical cleaning machine is improved.

The invention discloses an automatic silkworm cocoon hole cutting machine and a hole cutting method, the radial direction of a disk surface of a cocoon separating disk is provided with 2 rectangular slots that are symmetrical along the center of the cocoon separating disk, a horizontal cocoon conveying belt is positioned below the cocoon separating disk, the left end of the cocoon conveying belt is positioned under the cocoon separating disk, the right end of the cocoon conveying belt is tightly connected with the left end of a cocoon conveying passage, a cocoon pushing mechanism is arranged at an upper right position of the cocoon conveying passage, and a photosensitive sensor is installed on the cocoon pushing mechanism; a conveyor belt, an active roller wheel and a passive roller wheel are arranged on the right side of the cocoon conveying passage, a fixture component is fixedly connected on the conveyor belt, a positioning and clamping mechanism is arranged at a conveyor belt position between the active roller wheel and the passive roller wheel, a pushing plate that pushes the fixture to make the fixture open is positioned on the rear side of the positioning and clamping mechanism; a cutting mechanism is arranged at the upper right position of the passive roller wheel, and a cocoon shell separating mechanism is arranged on the left side of the passive roller wheel; batched and automatic hole cutting can be carried out on the silkworm cocoon of different sizes, silkworm chrysalis and cocoon shells can be separated automatically, the positioning is reliable, the cocoon for egg production can not be crushed or injured due to cutting, the cocoon cutting quality is good, and the efficiency is high.

The invention relates to the field of power construction technology, and particularly to a floor type handcart switchgear integrated track. The floor type handcart switchgear integrated track comprises a left-handed screw, a right-handed screw and a screw combined operating rod. The left-handed screw and the right-handed screw are fixedly connected with two ends of the screw combined operating rod. The left-handed screw and the right-handed screw are in threaded connection with an integrated track. The integrated track comprises a fixed track base, a fixed track, a spacing bent trough and an auxiliary track. The auxiliary track comprises a base plate, a spacing bent plate, and a pair of side tracks which are parallelly arranged on the base plate. A guiding trough is formed between the twoside tracks. The side track at the side which is far from the spacing bent plate is provided with a bell mouth guiding trough which is outwards opened. The base plate at the bell mouth guiding troughis an oblique surface which inclines downwards. The floor type handcart switchgear integrated track realizes a fact that a switchgear handcart can be more safely, stably, conveniently and accurately pushed into the switchgear. Furthermore the floor type handcart switchgear integrated track has advantages of simple structure, convenient operation and effective efficiency improvement and safety improvement of personnel.

The invention belongs to the technical field of rail vehicle couplers, and in particular relates to a coupler and a locking method thereof. The coupler includes a gib head, on which a sliding part is arranged; a fixing device, installed on the end wall of the car body, with a guide rail formed on one side edge, and a locking block is arranged on the fixing device; the hook The head is also provided with a locking device, driven by an external force, the slider on the hook head moves along the guide rail to the direction of the locking block until the locking device cooperates with the locking block, To realize the locking of the coupler, the folding locking, unlocking, or straightening locking process of the present invention can be completed with one hand without too much manual intervention, the action track is clear and clear, and the operation is convenient, efficient and automatic.
