[0021] The following specific implementation contents provide a variety of different embodiments or examples for implementing the utility model. Of course, these are only embodiments or examples and are not intended to be limiting. In addition, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present invention and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0022] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:
[0023] like Figures 1 to 2 The drawer guide rail of a laboratory cabinet shown in the figure comprises a first track 1 and a second track 2 which are arranged opposite to each other, the second track 2 being provided with an embedded convex edge 21 along the length direction, and the first track 1 being provided with a bridge frame groove 11 along the length direction, the embedded convex edge 21 can be cooperated and embedded in the bridge frame groove 11, so that the embedded convex edge 21 can fit the side wall of the bridge frame groove 11 and reciprocate along the length direction of the bridge frame groove 11 to drive the second track 2 to reciprocate along the length direction of the first track 1 relative to the first track 1. The drawer guide rail of the laboratory cabinet in this embodiment adopts the cooperation of the embedded convex edge 21 and the bridge frame groove 11, and frictionally slides between the first track 1 and the second track 2, so that the first track 1 and the second track 2 have the function of sliding guide rails. Compared with the existing transmission pulley guide rails, the structure is simpler and more durable in acidic, alkaline and corrosive laboratory environments.
[0024] At least two bridge frame flanges 12 are protruding from the first rail 1 along the length direction, and the space between adjacent bridge frame flanges 12 forms a bridge frame groove 11. The side walls of the bridge frame groove 11 are provided with smooth polished friction surfaces 111, wherein, preferably, the side walls of the bridge frame groove 11 and the side walls of the embedded flanges 21 are provided with polished friction surfaces 111. The provision of the polished friction surfaces 111 can make the bridge frame flanges 12 slide more freely in the bridge frame groove 11.
[0025] The width of the bridge groove 11 is greater than the width of the embedded flange 21, wherein, further, the recessed depth of the bridge groove 11 is greater than the protruding height of the embedded flange 21, so that when the embedded flange 21 is embedded in the bridge groove 11, a reserved area 112 is formed between the top of the embedded flange 21 and the bottom of the bridge groove 11. Appropriate space is reserved in the design to ensure that the flange can be easily embedded in the groove for easy use.
[0026] The first rail 1 is provided with a first substrate 13 for supporting a plurality of bridge flanges 12 along its length direction, and the second rail 2 is provided with a second substrate 22 for supporting an embedded flange 21 along its length direction, wherein preferably, the first substrate 13 and the plurality of bridge flanges 12 are an integrally formed structure, the second substrate 22 and the embedded flange 21 are an integrally formed structure, and both the first rail 1 and the second rail 2 are made of PP plastic. In a laboratory environment, the first rail 1 and the second rail 2 made of PP plastic have the properties of being resistant to strong acids and alkalis and corrosion-resistant compared to metal materials, and are lighter and more convenient when sliding.
[0027] In terms of structural optimization, a molded cavity 3 is provided inside the embedded flange 21, and a plurality of bridge flanges 12 are also provided inside with a molded cavity 3, which can reduce the weight of the guide rail.
[0028] The width of the first substrate 13 is greater than that of the second substrate 22. Then, the first substrate 13 is used to be fixed on the cabinet body of the laboratory bench cabinet, and the second substrate 22 is used to be fixed on the drawer of the laboratory bench cabinet. The reciprocating movement of the drawer relative to the cabinet body drives the reciprocating movement of the second substrate 22 relative to the first substrate 13, so that the cooperation between the guide rail and the laboratory bench cabinet is more reasonable in structure.
