The invention belongs to the technical field of fluid braking equipment, and particularly relates to a safety limiting device for a pull rope oil cylinder, which comprises a fixed frame, a sliding base and a hydraulic oil cylinder, the device further comprises a stable transmission mechanism. On one hand, in the stretching and retracting process of the hydraulic oil cylinder, the sliding base is driven to move in the mode that the fixed pulley pushes the transmission steel cable, and in the moving process, due to the fact that the fixed pulley and the transmission steel cable are symmetrically distributed on the upper side and the lower side of the hydraulic oil cylinder, tension of the transmission steel cable on a connecting piece is more balanced; on the other hand, due to the arrangement of the fixed pulley and the sliding base, under the condition that the stroke of the sliding base is fixed, the stroke of the hydraulic oil cylinder is halved, the requirement for the rigidity of the hydraulic oil cylinder is lowered, and the bending probability of the hydraulic oil cylinder is lowered; the stability of the hydraulic oil cylinder for driving the sliding base to move is further enhanced.

The utility model relates to a kind of driving structure, belong to microfluidic chip technical field, specifically a kind of liquid driving structure of microfluidic chip;In the utility model, when elastic film is used for a long time, limit frame is removed, so that limit frame and fixed frame separate, then elastic film is removed, new elastic film is sleeved on limit column, then limit frame is covered, and elastic film is fixed, so that elastic film is replaced easily, cooperation is carried out by motor, carousel, threaded rod, threaded block, connecting column, sliding frame and extruding roller, the speed of reciprocating movement of extruding roller is adjusted by the rotation of motor, so as to adjust the flow rate of liquid, when the flow of liquid needs to be adjusted, threaded rod is rotated, since threaded block is screw thread connected on threaded rod, so threaded rod moves along with the rotation of threaded block, drives connecting column to move, so that the range of sliding frame movement reduces, the extrusion degree of extruding roller to elastic film is reduced, so as to control the flow of liquid, improve the practicability of the device.

This utility model relates to the field of curved glass processing technology and discloses a 3D glass pad printing head that can reduce ink overflow, dimensional deviation, edge chipping, and fragmentation defects in products. It includes a base plate, a pad body, and an elastic pad printing head connected sequentially from bottom to top. The top surface of the elastic pad printing head is a convex arc surface. The top surface of the elastic pad printing head includes a textured anti-adsorption area formed in the middle, an annular ink-taking area surrounding the anti-adsorption area, and an annular ink-separating area located between the textured anti-adsorption area and the annular ink-taking area. The textured anti-adsorption area is provided with a plurality of first elastic ribs arranged side by side along the width direction of the elastic pad printing head and attached to the top surface of the elastic pad printing head, and a plurality of second elastic ribs arranged side by side along the length direction of the elastic pad printing head and attached to the top surface of the elastic pad printing head. The first elastic ribs and the second elastic ribs are intersected and connected to form a mesh structure. At least a portion of the first elastic ribs or the second elastic ribs is higher than the highest point of the top surface of the elastic pad printing head.

The utility model discloses a kind of electronic chip double-sided drying devices, it is related to chip processing technical field, including the intermittent turnover subassembly being installed in the both sides of drying box inside one end, the one end of intermittent turnover subassembly is provided with elastic resistance and pressure subassembly;Wherein intermittent turnover subassembly includes motor, the output of motor is provided with dialing disc, the top of dialing disc is provided with dialing rod, the top and bottom of the one end of dialing disc away from motor are all provided with support rod, are all provided with linkage disc above dialing disc, the outside of linkage disc is evenly provided with multiple groups of linkage gap, the top and bottom of the one end of linkage disc away from motor are all provided with support rod.The utility model is driven dialing rod by motor of intermittent turnover subassembly under the action of electric power and dialing linkage disc, realize intermittent turnover, not only make chip rotation heat evenly, chip can also be avoided to cause damage;Chip clamping by elastic resistance and pressure subassembly, because the degree of chip extrusion is reduced by the resilience of elastic member clamping, guarantee chip integrity.

This utility model discloses a car interior handrail cover, including a rotating plate hinged to the top of the storage compartment. A connecting plate is slidably mounted on the surface of the rotating plate, and the surface of the connecting plate is detachably covered with a soft fabric. The rotating plate has two symmetrically distributed limiting grooves inside, with a slot between the two limiting grooves, and the slot communicating with the two limiting grooves. Two symmetrically distributed sliders are fixedly connected to the bottom of the connecting plate, and the sliders are slidably mounted within the limiting grooves. Two mutually movable baffles are provided inside the slot, with both ends of the baffles slidably connected to the inner wall of the slot. In this utility model, by operating the drive assembly, the distance between the two baffles decreases, reducing the degree of compression → reducing friction → reducing the sliding resistance of the sliders. At this time, the driver and passengers can easily push the connecting plate, improving operational convenience (especially suitable for one-handed adjustment scenarios).

The application relates to the technical field of medical devices, in particular to a feces softening device and a picking device for constipation patients, wherein the feces softening device for constipation patients comprises a rod body, a movable block and a liquid pipe; a first sliding groove is arranged on the rod body; a first cavity is formed between the movable block and the first sliding groove; the first cavity is connected with a control assembly; the liquid pipe is fixed on an extending end; a plurality of liquid outlets are arranged at intervals in a first liquid pipe section, a second liquid pipe section and a third liquid pipe section; when the movable block is retracted into the rod body, the first liquid pipe section, the second liquid pipe section and the third liquid pipe section are communicated; when the movable block is extended from the first side, the movable block abuts and extrudes the first liquid pipe section, and can reach a degree of cutting off the liquid pipe. The feces softening device and the picking device for constipation patients can improve the convenience of family members or nurses in assisting patients in defecation by hand methods, and improve the smoothness of feces excretion.

The application discloses a forming die and forming method of a composite material component with a gradually-changing cross-section feature, and belongs to the technical field of composite material component manufacturing. The forming die mainly comprises an upper die, a bottom die, a core block and a middle frame edge strip, wherein the core block comprises a central core block and a plurality of occupying core blocks, and the middle frame edge strip comprises four independent edge strips. When the pre-impregnated material is laid in the forming die, the occupying core blocks are used for occupying, the middle frame edge strip is used for fastening, and pre-compaction operation is performed in combination with a pre-compaction tool and an occupying tool, so that the composite material component with the gradually-changing cross-section feature can be formed. The application can reduce the product extrusion caused by the cooling shrinkage of the mold steel material caused by the thermal expansion factor, the resin enrichment caused by the mold extrusion fluctuation of the thin-thick feature structure area, improve the heat transfer efficiency, control the resin viscosity, and effectively improve the product forming quality.
