DETAILED DESCRIPTION

[0021] like Figures 1 to 4 As shown, the utility model relates to an adjustable shelf of a refrigerated display cabinet, which includes a cabinet body 1 and a shelf adjustment mechanism 2 arranged in the cabinet body 1.

[0022] Specifically, such as Figure 1 ,to Figure 3 As shown, the shelf adjustment mechanism 2 includes a screw rod 201, a slide rail 202 and a plurality of placement plates 203 with one end passing through the screw rod 201. The two ends of the screw rod 201 are fixedly connected to the inner walls of the two ends of one side of the cabinet body 1, and one side of the slide rail 202 is fixedly connected to the inner wall of the other side of the cabinet body 1. The placement plate 203 step is provided with a circular hole 2031, the screw rod 201 is passed through the circular hole 2031, and the circular hole 2031 is connected with a threaded sleeve 204 for limiting rotation. The threaded sleeve 204 is threadedly connected to the surface of the screw rod 201. The placement plate 203 is slidably connected to the slide rail 202 at two ends, and one end of the threaded sleeve 204 extends to the bottom of the placement plate 203. The placement plate 203 is provided with a chain placement plate 203 external installation along the open side of the cabinet body 1. The mounting groove 2032 has a rotating shaft 205 connected thereto for rotation. A handwheel 206 is fixed on the surface of the rotating shaft 205. One side of the handwheel 206 extends to the outside of the mounting groove 2032. One end of the rotating shaft 205 extends to the bottom of the placement plate 203 and provides a toothed disc and chain transmission with one end of the threaded sleeve 204. The handwheel 206 is rotated to drive the rotating shaft 205 to rotate in the mounting groove 2032. The rotating shaft 205 drives the threaded sleeve 204 to rotate within the circular hole 2031. The threaded sleeve 204 spirally rises or falls on the surface of the screw rod 201, driving the other end of the placement plate 203 to rise or fall on the slide rail 202, thereby independently adjusting the position of each placement plate 203 to improve the utilization rate of the space in the cabinet 1.

[0023] Further, such as Figure 2 As shown, a limiting ring 2041 is fixedly provided on the middle surface of the threaded sleeve 204, and a limiting groove 2033 adapted to the limiting ring 2041 is opened in the circular hole 2031 relative to the limiting ring 2041. The rotation of the threaded sleeve 204 drives the limiting ring 2041 to rotate in the limiting groove 2033, thereby driving the placement plate 203 to rise or fall.

[0024] Furthermore, if Figure 2As shown, another section of the placement plate 203 is provided with a slider 207, which slides with the slide rail 202 in a limited position, and the other end of the placement plate 203 rises or falls on the slide rail 202 through the slider 207 to prevent the placement plate 203 from rotating; a plurality of slide grooves 2034 are provided on the surface of the placement plate 203, and a clamping assembly 208 is provided in the slide groove 2034. The clamping assembly 208 is used to fix the beverage to prevent the beverage from collapsing when the position of the placement plate 203 is adjusted.

[0025] It is worth noting that if Figures 1 to 4 As shown, the clamping assembly 208 includes a guide rod 2081 and a plurality of X-shaped clamping blocks 2082. The two ends of the guide rod 2081 are respectively fixed to the inner walls of the two ends of the slide 2034. The X-shaped clamping block 2082 is arranged on the top of the guide rod 2081, and the bottom of the X-shaped clamping block 2082 is fixedly connected to a moving block 2083. The moving block 2083 is movably sleeved on the surface of the guide rod 2081, and the guide rod 2081 is sleeved with a spring 2084 between two adjacent moving blocks 2083. The two ends of the spring 2084 are respectively fixed to the two adjacent moving blocks 2083. The opposite surfaces of the blocks 2083 are fixedly connected. When placing a beverage, the two adjacent X-shaped clamping blocks 2082 are moved to the sides by hand. The two adjacent X-shaped clamping blocks 2082 drive the moving block 2083 at the bottom to move in the opposite direction along the guide rod 2081 in the slide groove 2034, and at the same time stretch the spring 2084 to place the beverage between the two adjacent X-shaped clamping blocks 2082. The spring 2084 is reset to drive the two adjacent X-shaped clamping blocks 2082 to clamp and fix the beverage to prevent the beverage from collapsing when the position of the placement plate 203 is adjusted.

[0026] It is worth noting that Figure 4 As shown, the cross section of the slide groove 2034 is rectangular, and the moving block 2083 is adapted to the slide groove 2034 to prevent the X-shaped clamping block 2082 from flipping over, thereby ensuring the stability of the beverage clamping.

[0027] It is worth emphasizing that if Figure 4 As shown, both sides of the X-shaped clamping block 2082 are in the shape of arc surfaces that are concave toward the middle of the X-shaped clamping block 2082, and both sides of the X-shaped clamping block 2082 can clamp and fix the beverage.

[0028] Working principle: This embodiment provides an adjustable shelf of a refrigerated display cabinet. When in use, the two adjacent X-shaped clamping blocks 2082 are manually moved to the sides. The two adjacent X-shaped clamping blocks 2082 drive the moving blocks 2083 at the bottom thereof to move in the opposite direction along the guide rod 2081 in the slide groove 2034, and at the same time, the spring 2084 is stretched to place the beverage between the two adjacent X-shaped clamping blocks 2082. The spring 2084 resets and drives the two adjacent X-shaped clamping blocks 2082 to clamp and fix the beverage. The hand wheel 206 is turned to drive the rotating shaft 205 to rotate in the mounting groove 2032. The rotating shaft 205 drives the threaded sleeve 204 to rotate within the circular hole 2031. The threaded sleeve 204 spirally rises or falls on the surface of the screw rod 201. The rotation of the threaded sleeve 204 drives the limiting ring 2041 to rotate in the limiting groove 2033, driving the other end of the placement plate 203 to rise or fall on the slide rail 202 through the slider 207, thereby independently adjusting the position of each placement plate 203.

[0029] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
