[0002] In chemical laboratories, various glassware, such as flasks, test tubes, graduated cylinders, and waste bottles, need to be cleaned and dried after use for the next time. Currently, the main method of drying is to place the glassware upside down on a drying rack and let it air dry naturally. This method is not only inefficient, but also leaves water stains or other marks on the inner walls of the glassware after drying, affecting its subsequent use. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable glass instrument drying rack structure to solve the problems of low drying efficiency and water stains and other marks left on the inner wall of the glass instrument after drying.

[0004] To achieve the above objectives, the inventor, drawing on years of experience in chemical laboratories, has developed the following technical solution through extensive design, continuous exploration, and improvement: an adjustable glassware drying rack structure, comprising a base, a vertical support plate fixed to the symmetrical edge of the top surface of the base, a horizontal limiting plate fixed to the top surface of the vertical support plate, a plurality of circular through holes provided on the horizontal limiting plate, a support plate provided on the top surface of the base, a lifting electric rod vertically fixed inside the base, and the top of the lifting electric rod fixed to the center of the bottom surface of the support plate;

[0005] Several drying tubes are fixed on the support plate, and several air outlet holes are fixed on the upper side wall of the drying tubes. A cavity is provided inside the support plate, and an electric heating block is fixed inside the cavity. A small fan connected to the cavity is fixed at the end of the support plate. An air guide hole is provided between the drying tube and the top wall of the cavity.

[0006] The top surface of the transverse limiting plate is provided with a limiting cavity concentric with the circular through hole;

[0007] A rubber scraper is detachably installed at the top of the drying tube.

[0008] A further preferred embodiment is that: the end of the drying tube is provided with a snap-fit ​​hole, and a snap-fit ​​post is fixed at the center of the end face of the rubber scraper; the snap-fit ​​post is snapped into the snap-fit ​​hole.

[0009] A further preferred embodiment is that the diameter of the circular through hole is smaller than the inner diameter of the glass instrument, the diameter of the limiting cavity is larger than the outer diameter of the glass instrument, and the diameter of the drying tube is smaller than the diameter of the circular through hole.

[0010] A further preferred embodiment is that a power supply is fixed inside the base, and a control switch panel is provided on the top surface of the base.

[0011] A further preferred embodiment is that the bottom surface of the support plate is provided with a plurality of guide rods, the base is provided with a plurality of guide holes, and the lower part of the guide rods is movable and height-adjustable within the guide holes.

[0012] A further preferred embodiment is that the top surface of the rubber scraper has a spherical convex surface in the middle, and a V-shaped annular groove at the edge of the top surface.

[0013] A further preferred embodiment is that the rubber scraper is provided with a plurality of air venting and drainage holes that are open at both the top and bottom, and the air venting and drainage holes are located on the bottom wall of the V-shaped ring.

[0014] A further preferred embodiment is that the height of the limiting cavity is 1 / 3 to 1 / 4 of the total height of the glass instrument.

[0015] A further preferred embodiment is that the top of the circular through hole has a protruding edge that protrudes 2-5mm from the top surface of the transverse limiting plate.

[0016] Compared with the prior art, the present invention has the following advantages and advancements:

[0017] (1) Several circular through holes are provided on the transverse limiting plate, and a limiting cavity concentric with the circular through holes is provided on the top surface of the transverse limiting plate. Therefore, when the glass instrument is placed upside down, the bottom edge can be positioned above the circular through holes for limiting, and the edge of the glass instrument can be limited by the limiting cavity to prevent the glass instrument from tilting.

[0018] (2) A lifting electric rod is fixed vertically inside the base, and several drying tubes are fixed on the support plate. With the help of the electric heating block and a small fan, hot air can be blown into the drying tube and blown into the inner wall of the glass instrument through the air outlet hole on the drying tube to dry the inner wall of the glass instrument.

[0019] (3) A rubber scraper is detachably installed at the top of the drying tube. When the lifting electric rod drives the drying tube to move downward on the inner wall of the glass instrument, the bottom of the glass instrument is limited by the bottom wall of the limiting cavity of the transverse limiting plate. Therefore, the downward movement of the drying tube will drive the rubber scraper to move down inside the glass instrument, thereby scraping away water stains on the inner wall of the glass instrument, avoiding drying residue marks, and further improving the drying effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 3 As shown, an adjustable glass instrument drying rack structure includes a base 1, a vertical support plate 2 fixed on the symmetrical edge of the top surface of the base, a horizontal limiting plate 3 fixed on the top surface of the vertical support plate, and a plurality of circular through holes 4 provided on the horizontal limiting plate. The height of the vertical support plate can be processed and set as needed, specifically to match the height of the drying tube.

[0027] Furthermore, in this embodiment, a support plate 5 is provided on the top surface of the base, and a lifting electric rod 6 is vertically fixed inside the base. The bottom center of the support plate is fixed to the top of the lifting electric rod. The lifting electric rod can drive the support plate to rise and fall, thereby meeting the usage needs of different situations. It should be noted that the lifting electric rod is a conventional structure in the prior art, which can be gear-driven, screw-driven, etc. The inventor has simply applied this conventional product to the adjustable glass instrument drying rack structure of this utility model.

[0028] In this embodiment, a plurality of drying tubes 7 are fixed on the support plate, and a plurality of air outlet holes 8 are fixed on the upper side wall of the drying tubes. A cavity 9 is provided inside the support plate, and an electric heating block 10 is fixed inside the cavity. A small fan 11 connected to the cavity is fixed at the end of the support plate, and an air guide hole 12 is provided between the drying tubes and the top wall of the cavity. In this embodiment, the small fan is mainly used to blow in air, and the electric heating block is an electric heating mesh or electric heating tube, etc., mainly used to generate heat, which is blown into the drying tubes by the small fan and blown onto the inner wall of the glass instrument through the air outlet holes.

[0029] In this embodiment, the top surface of the transverse limiting plate is provided with a limiting cavity 13 concentric with the circular through hole; the height of the limiting cavity is 1 / 3 to 1 / 4 of the total height of the glass instrument 23.

[0030] The diameter of the circular through-hole is smaller than the inner diameter of the glass instrument, and the diameter of the limiting cavity is larger than the outer diameter of the glass instrument; the diameter of the drying tube is smaller than the diameter of the circular through-hole. The limiting cavity is mainly used to limit the glass instrument when it is inverted, preventing it from tilting or falling, and also preventing it from falling downwards. A rubber scraper 14 is detachably installed at the top of the drying tube. A snap-fit ​​hole 15 is provided at the end of the drying tube, and a snap-fit ​​post 16 is fixed to the center of the end face of the rubber scraper; the snap-fit ​​post snaps into the snap-fit ​​hole. With this structure, the rubber scraper can be disassembled and maintained as needed. For example, when used with glass instruments of different inner diameters, different rubber scrapers need to be replaced so that the edge of the rubber scraper fits against the inner wall of the glass instrument, allowing the inner surface of the glass instrument to be scraped when the rubber scraper is raised and lowered.

[0031] In practical applications, the top surface of the rubber scraper has a spherical crown-shaped convex surface in the center, and a V-shaped annular groove at the edge of the top surface. The width of the V-shaped annular groove is relatively narrow, so it does not affect the contact between the spherical crown-shaped convex surface and the bottom wall of the glass instrument. The rubber scraper is provided with several vertically permeable venting and draining holes 17, which are located on the bottom wall of the V-shaped annulus. Its spherical crown-shaped convex surface can make seamless contact with the bottom wall of the glass instrument, preventing residual marks on the bottom wall of the glass instrument. The venting and draining holes allow the rubber scraper to move upward when the glass instrument is fitted, forming a sealed air gap between it and the bottom wall of the glass instrument. Therefore, the internal air pressure and water accumulated by scraping the top edge of the rubber scraper can flow out through the venting and draining holes, preventing the rubber scraper from failing to contact the bottom wall of the glass instrument, thereby improving the drying effect during drying.

[0032] In this embodiment, a power supply 18 is fixed inside the base, and a control switch panel 19 is provided on the top surface of the base. The power supply can be AC ​​power or a battery, which can be selected as needed. The control switch panel is mainly used to control the start and stop of various components, such as the start and stop of the small fan, the start and stop of the heating block, and the start and stop of the electric telescopic rod. This is common technical knowledge in the prior art, so it is not described in detail.

[0033] In this embodiment, the bottom surface of the support plate is provided with a plurality of guide rods 20, and the base is provided with a plurality of guide holes 21. The lower part of the guide rods is vertically and vertically disposed in the guide holes. This design can prevent the support plate from tilting or swaying and shifting during lifting and lowering, and ensure the smooth and reliable lifting and lowering of the support plate.

[0034] In this embodiment, the top of the circular through hole is provided with a protruding edge 22 that protrudes 2-5mm from the top surface of the transverse limiting plate. This design can limit the inner wall of the glass instrument when it is inverted, preventing it from shaking or shifting.

[0035] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
