[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an edged sliding door for a commercial refrigeration cabinet, comprising a door frame, a slide groove, a plastic edged door and a glass door, wherein the inner wall of the door frame is provided with a slide groove, and a plastic edged door is slidably connected in the slide groove, and the plastic edged door is wrapped around the edge of the glass door, and a wheel groove is provided at the lower end of the plastic edged door, and a roller is arranged in the wheel groove, a wheel axle is installed at the center position of the roller, and sliders are installed at both ends of the wheel axle through bearings, the slider slides in the wheel groove, and a spring is vertically arranged on the upper end of the slider, and the device can absorb and relieve the impact force when the glass door is subjected to violent downward pressure or collision, thereby protecting the plastic edged door and the glass door, and reducing the adverse effects of collision and pressing on the plastic edged door and the glass door.

[0005] Preferably, the rollers are equidistantly arranged on the lower sides of the front and rear ends of the plastic edging. This structure is used to form multi-point support at the lower end of the plastic edging through the rollers, thereby ensuring a buffering effect.

[0006] Preferably, guide rails are provided on the inner walls on both front and rear sides of the upper end of the plastic edging, and a fixing strip is slidably connected between the two sets of guide rails, and a rubber strip is glued to the lower end of the fixing strip. This structure is used to make the rubber strip scratch the upper surface of the glass door by moving the fixing strip laterally when frost or condensation appears on the surface of the glass door, which makes it impossible for customers to directly see the goods in the refrigerator through the glass door. This makes it easier for customers to see the goods in the refrigerator without opening the glass door.

[0007] Preferably, balls are symmetrically installed on the lower sides of the front and rear ends of the fixing bar, and the inner wall of the guide rail is provided with guide grooves adapted to the balls, and the balls roll in the guide grooves. This structure is used to reduce the frictional resistance of the two ends of the fixing bar in the guide rail, thereby facilitating the lateral movement of the fixing bar.

[0008] Preferably, the interior of the rubber strip is a hollow structure, and the left and right ends of the rubber strip are squeezed inward to form an arc shape. This structure is used to make the lower surface of the rubber strip always fit with the upper surface of the glass door through the elasticity of the material of the rubber strip itself, thereby ensuring the cleaning effect during movement.

[0009] Preferably, the left and right corners of the lower side of the rubber strip are acute angles. This structure enables the rubber strip to scrape the surface of the glass door with its acute angle portion when moving laterally, thereby ensuring the cleaning effect.

[0010] Preferably, convex strips are symmetrically arranged on the left and right sides of the upper end of the fixing strip, and the side walls of the convex strips are provided with grooves. This structure is used to facilitate the user to push the fixing strip to move by buckling the grooves of the convex strips.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model, by arranging a spring, when the glass door is subjected to violent downward pressure or impact, the plastic edging will move downward in the slide groove and exert force on the spring, causing it to be compressed and deformed under the force, and in this process, the spring will absorb and alleviate the downward force exerted on the plastic edging through elastic deformation, thereby being able to provide collision protection for the plastic edging and the glass door, and at the same time, an adhesive strip is provided on the upper surface of the glass door, and when the surface of the glass door is not transparent due to condensation or frost, the adhesive strip can be scratched against the upper surface of the glass door by moving the fixing strip laterally, so as to clean the upper surface of the glass door, thereby facilitating observation of the goods in the refrigerator from the outside.
