Stretching device
Stretching device
[Product Model]: GYX-L21A-1
[Product Specifications]: 940 x 483 x 1183 (mm)
[Instructions for Use]: The user sits on the seat, grasps the armrests with both hands, places their feet on the pedals, and keeps their body upright. By slowly leaning backward, they fully stretch the lower back and core, allowing the seat to swing back and forth under the force of their own weight.
[Main Features]: Enhance the flexibility of the limbs and all spinal joints, thoroughly stretch the rectus abdominis, relax the lumbar and dorsal muscle groups, and improve the body’s overall coordination during physical activity.

Product Description
[Main Technical Parameters]:
◆ Directly buried type: the main upright posts are made of national‑standard galvanized steel pipes with a diameter of 114 mm and a wall thickness of 3 mm.
◆ The handrails are made of national‑standard steel tubing with a diameter of 33 mm and a wall thickness of 2.5 mm; the main frame’s bent tubes are made of national‑standard steel tubing with a diameter of 76 mm and a wall thickness of 3 mm.
◆ The seat panel is stamped from 4 mm‑thick cold‑rolled steel, ensuring an 8‑year service life; its perimeter features R2 rounded corners to prevent personal injury. The seat support uprights are made of 50×50×2.5 mm national‑standard square tubing, providing adequate load‑bearing strength.
◆ The limit switch employs a double-sided impact‑type internal stop, increasing the load‑bearing area. The impact pad is made of polyurethane, offering excellent impact resistance, superior elasticity, and outstanding resistance to aging and extreme temperatures. It incorporates two high‑quality bearings, while the limit‑stop side plates are fabricated from nationally standard steel sheet, ensuring compliance with performance requirements. All exposed edges feature R2 chamfers to minimize injury in the event of collisions.
◆ The embedding depth of the equipment upright shall be no less than 500 mm, and the underground dimensions shall be no less than 400 × 400 × 600 mm.
◆ The equipment nameplate is made of stainless steel, secured with pop rivets, and its edges are tightly fitted against the upright post to prevent snagging, scratching, or other damage.
◆ The top of the column is sealed to prevent rainwater from entering.
◆ The equipment has undergone relevant static load and stability tests in accordance with the GB 19272-2024 standard and complies with the standard’s requirements.
◆ The entire machine has no snagging, crushing points, shearing points, or pinching hazards; all apertures and gaps comply with the GB 19272-2024 standard.
◆ The components are cut using a laser cutting machine, ensuring high efficiency and precise positioning. For the bending process, a CNC pipe bender is employed, delivering accurate angles and an aesthetically pleasing finish. Prior to welding, all parts undergo degreasing to ensure that no oil or contaminants remain on the surface. Welding is performed with a CO₂‑shielded arc welder, using a mixed gas shielding atmosphere, resulting in clean, smooth welds that require no post‑weld grinding. A dust collection and treatment system is integrated to purify workshop air and safeguard worker health. Surface preparation utilizes shot blasting, achieving thorough rust removal and enhancing the adhesion of the powder coating. Electrostatic powder coating follows a two‑coat application process: first, an epoxy‑rich zinc‑based primer is applied, followed by a green‑friendly, environmentally compliant exterior powder coat. Imported electrostatic spraying equipment ensures uniform powder distribution and strong adhesion, producing a coating that is resistant to acids and alkalis, withstands humid‑heat conditions, resists aging and corrosion, and maintains an attractive appearance—making it well suited for humid environments and areas exposed to acid rain. The coating formulation contains no toxic elements. Powder recovery is handled by a cyclone‑type centrifugal separator, achieving a recovery rate of up to 98.6%, thereby conserving material, reducing dust pollution, and offering convenient operation while promoting energy efficiency and environmental protection.
◆ The equipment is packaged in a double-layer system, effectively preventing impacts during transit and ensuring the equipment remains undamaged.
