DETAILED DESCRIPTION
[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.
[0021] Example 1
[0022] like Figure 1-3As shown, a chemical teaching instrument drying device provided by the utility model comprises: a support plate 1, a drying structure 2 is arranged on the top of the support plate 1, when the teaching staff finishes the chemical teaching and cleans the experimental instrument, the drying structure 2 can be used to quickly dry the experimental instrument, the drying structure 2 comprises a fan box 21, a wind duct 22 is installed on one side of the fan box 21, and a plurality of vertical rods 23 are evenly installed on the top of the wind duct 22, when the teaching staff needs to dry the cleaned instrument, it is inverted on the vertical rod 23, when the fan box 21 is started, because the wind duct 22 and the plurality of vertical rods 23 evenly installed on the top are connected, when the fan box 21 sends wind outward, the wind can enter the interior of the vertical rod 23 through the wind duct 22, and then the inverted instrument is dried by the vertical rod 23, the outer side of the vertical rod 23 is symmetrically provided with a limiting structure 3, when the teaching staff inverts the instrument on the vertical rod 23 When the instrument is raised, the limiting structure 3 can limit the position of the instrument to prevent the instrument from shaking due to wind and thus colliding. The limiting structure 3 includes a movable part 31, a support frame 32 is installed on the outer side of the movable part 31, a rubber block 33 is installed at one end of the support frame 32, a movable ring 34 is installed on the outer side of the vertical rod 23, and the movable ring 34 is located below the support frame 32. A movable shaft 36 is installed on the outer side of the support frame 32 and the movable ring 34, and a connecting member 37 is installed between the two movable shafts 36. When the teaching staff needs to turn the instrument upside down, the connecting member 37, the support frame 32 and the rubber block 33 are lifted by lifting the movable ring 34 to invert the instrument. After inversion, the support frame 32 and the rubber block 33 are driven to expand outward through the movable shaft 36 and the connecting member 37. When the rubber block 33 is expanded and contacts the inner wall of the instrument, it can be limited and fixed to prevent movement.
[0023] When in use, the support frame 32 and the rubber block 33 can be controlled by the cooperation of the movable ring 34 and the connecting piece 37 to position the inverted instrument, preventing the instrument from moving during wind drying, thereby causing the instrument to collide with the vertical rod 23, providing protection for the chemical teaching instrument and increasing its service life.
[0024] Example 2
[0025] like Figure 1-3 As shown, a plurality of wind tunnels 24 are evenly arranged inside the vertical rod 23. When the teaching staff turns the instrument upside down on the vertical rod 23, the fan box 21 sends wind into the interior of the vertical rod 23 through the air duct 22, and then blows wind outward from the plurality of wind tunnels 24 evenly arranged inside the vertical rod 23. The blown wind can quickly dry the inside of the instrument.
[0026] Example 3
[0027] like Figure 1-3As shown, support blocks 35 are symmetrically installed on the outer side of the movable ring 34. When the teaching staff turns the instrument upside down, when the bottom of the instrument contacts the support block 35, the support block 35 and the movable ring 34 are moved downward due to gravity. The support block 35 and the movable ring 34 move through the movable shaft 36 and the connecting piece 37 to drive the support frame 32 and the rubber block 33 to move synchronously and expand the rubber block 33 outward.
[0028] Example 4
[0029] like Figure 1-3 As shown, a protective structure 4 is provided on the outside of the rubber block 33. After the teaching staff dries the chemical instrument, the rubber block 33 can be protected by the protective structure 4 to prevent the outside from contacting the rubber block 33 and causing pollution to it. The protective structure 4 includes a protective sleeve 41. A mounting groove 42 is provided inside the protective sleeve 41. The rubber block 33 is located inside the mounting groove 42. When the use of the rubber block 33 is finished, the rubber block 33 is inserted into the mounting groove 42 provided inside the protective sleeve 41. At this time, the protective sleeve 41 is located on the outside of the rubber block 33 to provide protection for it.
[0030] Example 5
[0031] like Figure 1-3 As shown, a slide groove 43 is provided on the top of the protective sleeve 41, and a slider 44 is installed inside the slide groove 43. A groove 45 is provided on one side of the rubber block 33, and an interlocking block 46 is installed at the bottom of one end of the slider 44. The interlocking block 46 is made of rubber and is located inside the groove 45 for interlocking connection. After the teaching staff finishes drying, they pull the slider 44 to drive the interlocking block 46 installed at the bottom of one end to extend outward along the slide groove 43. After the rubber block 33 is inserted into the installation groove 42, the groove 45 on one side of the rubber block 33 corresponds to the interlocking block 46. The slider 44 is then pushed back along the slide groove 43. At this time, the interlocking block 46 enters the groove 45 for interlocking connection. The rubber block 33 can be protected by the cooperation of the protective sleeve 41, the slider 44 and the interlocking block 46 to prevent the rubber block 33 from being contaminated by external contact, thereby causing contamination to the cleaned chemical instrument during use.
[0032] When in use, the engaging block 46 is driven to disengage from the groove 45 by pulling the slider 44, and then the protective cover 41 is separated from the rubber block 33. After separation, the connecting piece 37, the support frame 32 and the rubber block 33 are lifted by lifting the movable ring 34 so as to invert the instrument. When the instrument is inverted, after the bottom of the instrument contacts the supporting block 35, the supporting block 35 and the movable ring 34 are moved downward due to gravity, and the supporting block 35 and the movable ring 34 move through the movable shaft 36 and the connecting piece 37 to drive the supporting frame 32 and the rubber block 33 to move synchronously and expand the rubber block 33 outward. After the rubber block 33 contacts the inner wall of the instrument, it can be limited and fixed. Then the fan box 21 is started to transport the wind to the inside of the vertical rod 23 through the wind duct 22, and then the wind is discharged outward from the wind tunnel 24 to dry the inverted instrument.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
