The invention provides a device for measuring the spring stiffness coefficient. The device includes a protective supporting shell, a limiting supporting frame structure with a scale line, a stiffnesscoefficient measurement spring structure, test balls, a plastic indicator plate, a convenient-to-carry protective cover structure capable of marking, a foldable protective supporting base structure, an anti-falling stop block, a clamping hole and a fluorescent pasting strip, and the limiting supporting frame structure with the scale line is fixed on the front surface of the protective supporting shell. According to the device for measuring the spring stiffness coefficient, through arrangement of limiting screws and an adjusting handle, the grasped adjusting handle is twisted advantageously, the distance between the limiting screws is adjusted, and the need of placement of test balls with different diameters is met; through arrangement of a protective cover plate, a portable grab handle anda tightly propping bolt, the measuring device is carried by the grasped portable grab handle advantageously, and the convenience and rapidity of use are increased; and through arrangement of a rotating shaft, a fixing sleeve, a protective baffle and a fixing clamping column, the action of shielding protection can be achieved from the front advantageously, and the test balls are prevented from falling.

The invention relates to the technical field of reflective materials, and provides a reflective hot applied film and a preparation method thereof. The reflective hot applied film comprises a PE / PET composite film, a glass bead layer, an adhesive layer, an electroplated layer and a hot melt adhesive layer which are laminated and arranged sequentially from bottom to top, wherein glass beads have a particle size of 200-500-mesh. The defects that in the prior art, a PE / PET composite film on the surface of a reflective film cannot be torn easily, and further printing cannot be performed on the surface of the reflective film in the later stage are overcome.

The invention discloses an anti-smashing safety shoe. The anti-smashing safety shoe comprises a shoe body, a protection unit, a mounting unit and a short tube, wherein the short tube is arranged on the right side of the top end of the shoe body, a reinforcing unit is arranged at the top end of the front side face of the short tube, and a breathable unit is arranged on the front side face of the shoe body; And the protection unit comprises two supporting blocks, clamping holes, inserting blocks, an elastic bolt and an anti-smashing steel plate, the two supporting blocks are correspondingly arranged in the middle of the top end of the shoe body front and back, the inserting blocks are arranged at the front end and the rear end of the right side face of the anti-smashing steel plate, and areinserted into inserting grooves in the left side faces of the supporting blocks, the clamping holes are formed in the top ends of the supporting blocks, elastic plug pins are arranged at the top endsof the inserting blocks, and are connected with the clamping holes in an inserted mode. The anti-smashing safety shoe further comprises a base, a fixing block and a shoe sole, the base is arranged inthe middle of the bottom end of the shoe body, and the mounting unit is arranged at the bottom end of the base. The anti-smashing safety shoe is convenient to disassemble, high in safety and good in protection effect.

The invention provides an ecological protection slope based on a multi-protection device for a water conservancy project. The ecological protection slope comprises a to-be-protected soil slope, a nameboard, a fixing rod, a reflecting plate, a fixing plate, an upper protection plate, a locking bolt, a main protection fixing cone structure, a slope protection upper protection guardrail structure, afirst-stage V-shaped connecting plate, a second-stage V-shaped connecting plate, an ecological protection planting turf structure, a connection bolt, a side protection and maintenance guardrail structure, a square head bolt and an auxiliary slope fixing cone; and the name board is arranged at the upper end of the fixing rod in a screwed mode. Guardrail bodies, ejector rods, an end protective handrail and end rods are arranged, so that the safety protection effect is improved; connecting belts, a protective net and linking plates are arranged, so that the use safety of the protective slope isimproved, and meanwhile, the risk that a maintainer falls into the slope bottom carelessly can be avoided; and maintaining guardrails, connecting plates and a side protecting connecting plate are arranged, so that nursing personnel facilitates nursing of the protective slope and can be used for holding the maintaining guardrails.

The invention relates to the field of manufacturing of reflective fabrics and in particular relates to a method for preparing a high-brightness reflective fabric. The method comprises the following process flows: (1) coating a bead embedding adhesive layer on a PET film, and drying through a drying box, thereby obtaining a bead embedding adhesive layer; (2) placing the bead embedding adhesive layer prepared in the step (1) in a glass bead groove for embedding beads, embedding the glass beads into the bead embedding adhesives for realizing bead embedding through the actions of a composite roller and a compression roller; (3) transferring a semi-finished product subjected to bead embedding in the step (2) into coating equipment, turning metals from a solid state into a gaseous state through a resistance heating mode, and desublimating the metals into a metal coating when meeting a bead embedding film; (4) coating a composite adhesive layer on the surface of a base fabric, drying the solvent, compounding a reflective layer, and compounding through blanching; and (5) stripping to remove the PET film and the bead embedding adhesive layer, thereby obtaining the finished product. The key control of the high-brightness reflective fabric refers to raw material selection and blending of the composite adhesive, namely the composite adhesive layer has the effect of adhering the reflective layer and the base fabric, the washing resistance of the composite reflective layer determines the quality of the washed product, the higher the viscosity of the composite adhesive is, the higher the washing resistance is, and the brightness of the washed high-brightness reflective fabric is higher.
