Anti-skid limiting device and vertical lumbar traction belt
ActiveCN222150254Ueasy to useImprove user experienceFracturePhysical medicine and rehabilitationLumbar traction
The utility model discloses an anti-skid limiting device and a vertical lumbar traction belt. The anti-skid limiting device comprises at least two check blocks, each check block comprises a protruding part and a sharp part located below the protruding part, and the horizontal cross section of each sharp part is smaller than that of the corresponding protruding part. The sharp part is used for being inserted between a waist band of the lumbar traction band and the waist of a user or inserted on the waist band so as to prevent the waist band from moving upwards. The device is used for the vertical lumbar vertebra traction belt, the problem that a waistband moves upwards in the using process can be effectively solved, use is convenient, the device can be matched with most existing lumbar vertebra traction belts, and the using effect and the using experience of the vertical lumbar vertebra traction belt can be improved.

House building hydraulic climbing scaffold system
PendingCN119641066AImprove work efficiencyprevent moving upScaffold accessoriesArchitectural engineeringHouse building
The invention discloses a housing building hydraulic climbing scaffold system, which relates to the field of building construction, comprises a bottom box and a construction platform positioned above the bottom box, and is characterized in that moving wheels are mounted at four corners of the bottom surface of the bottom box, and movable grooves communicated with the interior of the bottom box are formed in the four corners of the bottom box along the width direction of the bottom box; and an extension arm is slidably connected into each movable groove, telescopic connecting rods are arranged on the two sides of the upper surface of the bottom box, and the two telescopic connecting rods are located between the construction platform and the bottom box. When a construction platform ascends, the upper end of a connecting rope is driven to ascend together, at the moment, the connecting rope drives a winding wheel to rotate on two lug plates, meanwhile, rotating torsion is applied to a torsion assembly, and a bidirectional screw is in threaded connection with threaded holes in two extension arms, so that the extension arms can be driven to move and extend towards the outer side of a box body; the four extension arms are driven to extend outwards at the same time in the ascending process of the construction platform, and the working efficiency is improved.
