Embodiment 1

[0030] refer to Figure 1-4 As shown, the laboratory fume hood glass door guide rail mechanism provided in this embodiment includes a guide rail main body 1 , a glass guide rail splint 2 , a glass pressure plate 3 and a counterweight box 4 .

[0031] Among them, such as figure 2 As shown, the main body 1 of the guide rail is a double-layer structure, formed by integral die-casting, and has a compact structure, which can effectively reduce the process steps in the installation process, save installation time, and improve production efficiency; Along the length direction of the bottom panel, two guide strips 11 are arranged parallel to each other at intervals, and one guide strip 11 is arranged on the side panel of the upper layer of the guide rail body along the length direction of the side panel. The front and rear ends of the counterweight box 4 are correspondingly equipped with two guide wheels 5 and are cooperatingly installed in the guide strips 11 on the bottom panel, s...

Embodiment 2

[0038] refer to Figure 5 Shown is the laboratory fume hood glass door guide rail device provided in this embodiment, which includes the laboratory fume hood glass door guide rail mechanism 100 in Embodiment 1, the connecting shaft 10 , the synchronous belt and the synchronous wheel 9 . Wherein, the glass door guide rail mechanism 100 of the laboratory fume hood is relatively arranged on the left and right, the glass door is nested and installed in the glass nesting installation positions of the two guide rail mechanisms, and the two ends of the connecting shaft 10 are respectively installed on the glass doors of the two laboratory fume cabinets. In the bearing block 8 of the guide rail mechanism, the synchronous wheel 9 is installed on the two ends of the connecting shaft 10 and is located in the guide rail mounting bracket 7, and the counterweight box 4 is connected and driven by the synchronous belt and the synchronous wheel 9. In this way, by using the synchronous wheel 9,...

Abstract

The invention discloses a laboratory fume hood glass door guide rail mechanism and device. The mechanism comprises a guide rail main body, a glass guide rail clamping plate, a glass pressing plate anda counterweight box, wherein the guide rail main body is of a double-layer structure, and the surface of a bottom panel of a bottom layer of the guide rail main body is provided with two guide bars in the length direction of the bottom panel in parallel at intervals; a side panel of an upper layer of the guide rail main body is provided with one guide bar in the length direction of the side panel; the front and rear ends of the counterweight box are each provided with two guide wheels installed in the guide bars of the bottom panel in a cooperative manner; the front and rear ends of the glassguide rail clamping plate are each provided with one guide wheel installed in the guide bar of the side panel in the cooperative manner; and the glass pressing plate is fixedly installed on the uppersurface of the glass guide rail clamping plate. The mechanism is designed as a rolling friction structure, and the kinematic friction coefficient of the guide rail is reduced effectively; and noise is reduced, and the comfort degree in the lifting process of a glass door is improved.

Description

technical field [0001] The invention relates to laboratory equipment, in particular to a glass door guide rail mechanism and device of a laboratory fume hood. Background technique [0002] The existing laboratory fume hood door guide rail devices mostly use sliding friction guide strips and guide grooves, which have a large friction coefficient and are laborious, and when the operator uses improper force, it may cause the opposite guide rails to be out of sync. , the movement noise is large, and the overall structure is not compact, the volume ratio is large, and the installation and maintenance are not convenient. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiencies in prior art, provide a kind of laboratory fume hood glass door guide rail mechanism and device, to reduce the motion friction coefficient of guide rail, reduce noise. [0004] For realizing the above object, technical scheme of the present inventi...
