This invention discloses an integrated multi-nozzle air-assisted 3D printing nozzle, comprising an upper horizontal plate, a lower horizontal plate, m material feed cylinders, and a heating element, where m is 3-100. The upper horizontal plate is located above the lower horizontal plate, and the two together form an air chamber. An air inlet is provided on the air chamber. The top wall of the air chamber has m material feed cylinder channels, and the bottom wall has m gas channels. The m material feed cylinder channels and m gas channels are all vertically arranged and simultaneously connected to the air chamber. The m material feed cylinders are vertically arranged, and each material feed cylinder has a discharge port at its lower end. The m material feed cylinder channels, m gas channels, and m material feed cylinders correspond one-to-one. The top of the i-th material feed cylinder is located within and sealed to the i-th material feed cylinder channel, and its bottom is located within the i-th gas channel, with a gap between them for gas passage, i = 1, 2, ..., m. This invention has a simple structure and effectively solves the problems of existing technologies that cannot achieve multi-nozzle printing and simultaneous air-assisted 3D printing of multiple materials and colors.

The utility model discloses a hydraulic jacking old and dilapidated house integral deviation rectifying device, which belongs to the technical field of house deviation rectifying, and comprises a hydraulic jack body, the top of the hydraulic jack body is fixedly connected with a deviation rectifying mechanism, and the rear side of the deviation rectifying mechanism is welded with a reinforcing mechanism. A supporting plate in the deviation rectifying mechanism is fixed to the top of a hydraulic jack body to provide a stable bearing plane, supporting columns are arranged at the chamfers of the top of the supporting plate and matched with a deviation preventing plate at the top, lateral displacement of a house can be effectively limited, meanwhile, the supporting columns at the bottom of a bottom bearing plate are connected with a connecting plate, the vertical stability of the whole structure is enhanced, and the service life of the whole structure is prolonged. The reliability and durability of the device are further enhanced through the arrangement of the reinforcing mechanism, the connecting plate and the reinforcing rod net are welded to the rear side of the deviation rectifying mechanism, a stable triangular mechanical structure is formed, stress in the jacking process is dispersed, key parts are prevented from being damaged due to concentrated stress, and the connecting pipe and the nail entering pipe are designed to be communicated.

The utility model discloses a kind of perpendicularity detection devices of transmission shaft, it is related to transmission shaft detection technical field, including first mounting bracket, adjusting mechanism is installed in first mounting bracket inside, the utility model, through the cooperation track structure of three positioning blocks of annular arrangement, realize the multi-point synchronous locking and positioning of transmission shaft, positioning block is evenly distributed in track inside, track is rotated by external handle driving gear system, in the process of rotation, cam groove structure inside track guides positioning block to contract along radial direction synchronously, complete transmission shaft equidistant surrounding type lateral locking, effectively prevent shaking and skew, ensure detection accuracy and repeatability, simultaneously, by the pre-tightening force of spring extruding block and lifting rod down pressure, carry out constant pressure to transmission shaft top, to further improve vertical stability, realize all-around stable positioning and locking in three-dimensional direction, guarantee the stability and reliability in detection process.

The utility model discloses a pole piece gap measuring instrument device in the technical field of battery manufacturing and detection, which comprises a fixing frame, the top surface of a base and the top surface of a base are at the same plane height, the horizontal plane of the transmitting end of a laser displacement sensor and the bottom surface of a pressure plate are at the same level, and a bidirectional threaded rod is rotatably connected in a chute. One end of the two-way threaded rod rotatably extends to the outer end of the base, the two ends of the surface of the two-way threaded rod are rotatably sleeved with sliding rods in a threaded mode respectively, and the sliding rods are arranged in the sliding grooves in a sliding mode. And finally, data is displayed by observing the distance between the transmitting end of the laser displacement sensor and the surface of the base, namely measurement data of the battery pole piece gap, so that the measurement accuracy of the pole piece gap is improved.

The invention discloses an ultra-long-distance submarine cable laying device and method, and relates to the technical field of submarine cable laying, the ultra-long-distance submarine cable laying device comprises a base, the bottom of the base is connected with anchoring supporting legs, the upper part of the base is connected with a submarine cable clamping mechanism used for clamping a submarine cable, and the submarine cable clamping mechanism is connected with a sliding block; the sliding block is slidably connected with a sliding rod parallel to the axis of the submarine cable, the base is assembled and connected with a counter-force frame at the rear end of the sliding rod, the counter-force frame is connected with a hydraulic push rod, the output end of the hydraulic push rod is connected with the submarine cable clamping mechanism, and the submarine cable clamping mechanism is driven by the hydraulic push rod to do linear reciprocating motion along the sliding rod; the submarine cable clamping mechanism is used for clamping the submarine cable in the pushing construction process, and then continuous and uniform axial pushing force is applied to the submarine cable through the hydraulic push rod and forms a forward pulling-backward pushing synergistic effect with land side dragging force; the risks of cable stretching, armored layer offset, insulating layer damage and the like caused by too large dragging force are effectively relieved.
