This invention discloses a protective device for loading truck fuel tanks, including a fuel tank, with a protective device detachably mounted on the outside of the fuel tank; the protective device is configured as a hollow mounting box with an opening and closing door on the upper side; the outer wall of the mounting box is coated with PU paint, and the PU paint can be applied in multiple layers; the mounting box has a double-layer structure, with silicone blocks filling the space between the outer and inner layers; the mounting box contains a partition and anti-collision components; the anti-collision components are fixedly connected to the left side wall of the mounting box, and there are two anti-collision components, with another anti-collision component symmetrically mounted on the right side wall of the mounting box; the anti-collision components include a fixing plate, a first upright, a second upright, a push plate, and a buffer; by mounting the box, the outer wall of the fuel tank is effectively prevented from being contaminated with dust and oil, and the mounting box can be cleaned with a simple rinse, facilitating fuel tank maintenance.

The utility model discloses a kind of high-temperature-resistant conductive foam, including foam body, its foam body outer wall is equipped with heat insulation sleeve, the heat insulation sleeve outer wall is equipped with fire-retardant sleeve, the fire-retardant sleeve outer wall is equipped with conductive cloth, the utility model relates to conductive foam technical field;The high-temperature-resistant conductive foam, by tearing off release film and movable foam body is adhered to the position on the top of workpiece by the adhesion of adhesive layer, and by the mutual cooperation of fire-retardant sleeve and heat insulation sleeve under work, so that foam body has good high temperature resistance and avoids the occurrence of spontaneous combustion, under the cooperation of heat dissipation bar and heat dissipation port, heat inside foam body can be emitted outward, with good heat dissipation effect, by the mutual cooperation of reinforcing rib and connecting seat under work, so that foam body has good strength, when being pressed or receiving external impact, can prevent the problem of deformation damage of whole.

The utility model relates to the field of chemical fibre processing technology, concretely is a kind of chemical fibre paper tube mechanical gripper, including mounting seat, electromagnet, movable swing page and magnet strip, electronic commutator is provided in mounting seat, electromagnet is vertically arranged on mounting seat, electromagnet axis coincides with mounting seat axis, electronic commutator is electrically connected with electromagnet, each movable swing page is sequentially head-to-tail hinged, movable swing page at one end is fixed with mounting seat, magnet strip is installed on movable swing page, magnet strip can be mutually attracted / repel with electrified electromagnet.The utility model utilizes the movable swing page of surface state and resists paper tube inside to realize the action of grabbing, compared with the common point type contact gripper, the contact area is larger, not easy to slide, can guarantee paper tube grabbing effect, at the same time, can avoid that paper tube inside is damaged and deformed due to excessive force concentration, and simple structure is convenient for maintenance, has practical significance and popularization value, can produce good economic benefits.

This invention relates to the field of domain controllers, specifically to an airtightness detection device for a domain controller. The device includes a domain controller housing, with a first end cap and a second end cap respectively installed at both ends of the housing. A base plate is installed at the bottom of the housing. Two fixing holes are provided on each side of the housing along its width. A slide is provided on the underside of the base plate, and a base slidably connected to the slide is provided on the underside of the slide. Four positioning rods are evenly installed on the upper surface of the slide. A limiting ring is provided below the fixing holes. A driving component for moving the domain controller housing is installed on one edge of the upper surface of the base. A detection component for detecting the seal between the domain controller housing and the first and second end caps is installed on the side of the upper surface of the base away from the driving component. This invention has the following advantages: it avoids the second end cap being fully subjected to the extrusion force generated by the second cylinder, preventing the second end cap from being deformed and damaged by extrusion.

This invention belongs to the field of additive manufacturing technology, and particularly relates to a filament feeding device and a 3D printer. The device includes a main body with a fixed disk and a rotating turntable. The fixed disk has a drive roller and two straight grooves, while the turntable has two inclined grooves. A sliding block is slidably connected to both the straight and inclined grooves, and a driven roller is mounted on the sliding block. The turntable is connected to a worm gear drive mechanism. The drive roller and the two driven rollers together form a three-point support and clamping structure for the filament. The rotation of the turntable drives the two driven rollers to move radially synchronously, adapting to filaments of different diameters. A ring-shaped PTC heating device is provided at the filament outlet for continuous online drying of the filament. This invention achieves stable filament feeding through a three-point clamping structure, avoiding filament damage and deformation. It also integrates a synchronous drying function, effectively solving the problem of moisture absorption in the printing filament. It has the advantages of stable clamping, strong adaptability, and good drying effect.
