Description
Technical Field
[0001] This invention relates to the field of glass instrument technology, and more specifically to an optical glass rod that is easy to stir. Background Technology
[0002] Optical glass rods are essential tools in laboratories, typically used for stirring solutions. After stirring, the glass rod needs to be removed and placed on the work surface. Solution residue adhering to the rod can easily stain the work surface, and in the event of strong acids or alkalis, it can cause corrosion. Currently, the common practice is to rinse the stirred glass rod under running tap water before placing it on the work surface, or to suspend the end with the residue over a drain to prevent it from affecting the work surface. However, the former method can easily affect the concentration if stirring is stopped midway and new solvent is added and stirring resumes; the latter method can interfere with other cleaning operations in the drain. Therefore, there is an urgent need for an optical glass rod that facilitates stirring and solves these problems. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing an optical glass rod that is easy to stir, which can effectively solve the aforementioned problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a stirring rod body; one end of the stirring rod body is provided with a threaded connection end; it also includes a support member; the support member is threadedly connected to the threaded connection end, and the support member is slidably sleeved on the stirring rod body.
[0005] The above design increases the contact area between the operator's hands and the stirring rod, making it easier to grip the stirring rod during stirring. The support is movably mounted on the stirring rod. When adding solvent to the solution after stirring stops, the entire rod is positioned perpendicular to the upper end of the solution bottle. The support is then detached from the threaded connection end of the stirring rod and slid away from it. During this sliding motion, the support scrapes off the solution adhering to the stirring rod, causing it to fall into the solution bottle. The support is then slid to the end of the stirring rod furthest from the threaded connection end and placed inside the support. Finally, the stirring rod is supported on the work surface using the support. The height of the threaded connection end of the stirring rod is lower than the supported end (the end furthest from the threaded connection end). Any remaining solution flows along the gap between the stirring rod and the support into the support, preventing dripping onto the work surface.
[0006] Preferably, the support member comprises:
[0007] A connector body, wherein the inner wall of the connector body is provided with an internal thread, and the internal thread of the connector body is detachably connected to the threaded connection end;
[0008] A frustum-shaped support body, wherein the inner diameter of the frustum-shaped support body is larger than the inner diameter of the connector body, and the two are integrally formed, and the inner wall of the connection end of the frustum-shaped support body and the connector body forms a scraped edge.
[0009] With the above design, during the sliding process, the scraper scrapes the solution off the outer wall of the stirring rod, and the scraped solution is guided to drip into the solution bottle along the inner wall of the frustum-shaped support; the frustum-shaped support provides inclined support for the stirring rod.
[0010] Preferably, the outer wall of the wide end of the frustum-shaped support is provided with several support planes to improve stability during support.
[0011] Preferably, the support plane has several ridges integrally formed to increase the friction when supporting, and at the same time make it easy to hold and prevent slipping during stirring.
[0012] Preferably, the wide end of the frustoconical support is detachably connected to a scraper ring, the inner ring wall of which is slidably fitted into contact with the outer wall of the stirring rod; the scraper ring performs preliminary scraping of some of the solution adhering to the outer wall of the stirring rod, and together with the scraper edge, achieves a double scraping effect.
[0013] Preferably, the scraper ring has several scraper ring drainage holes. Some of the solution that has not been scraped off by the scraper ring enters the interior of the frustum-shaped support body through the scraper ring drainage holes. Under the secondary scraping action of the scraper edge, it is scraped together to the end of the stirring rod away from the threaded connection end. Under the action of the solution's own gravity and the scraping action of the scraper edge, the solution drips from the scraper ring drainage holes into the solution bottle.
[0014] Preferably, a liquid guiding groove is provided at the scraping edge position in the outward ring direction, and a plurality of liquid guiding holes are provided in a ring shape on the inner wall of the frustum-shaped support, and the liquid guiding holes are all connected to the liquid guiding groove.
[0015] With the above design, when the scraper begins to scrape off the solution adhering to the outer wall of the stirring rod, the solution flows along the scraper into the liquid guide groove and enters the liquid guide hole under the action of gravity. Then, it flows into the solution bottle through the liquid guide hole, avoiding direct contact between the solution and the inner wall of the frustum-shaped support. This also prevents the solution from sticking to the entire stirring rod body during the process of the support sliding back to the threaded connection end.
[0016] Preferably, the end of the liquid guiding hole that is connected to the liquid guiding groove has a frustum-shaped liquid guiding port, so that the solution flows into the liquid guiding hole more quickly.
[0017] Preferably, the threaded connection end is detachably connected to the stirring rod body.
[0018] Preferably, one end face of the threaded connection end is integrally formed with a threaded connection rod, and a threaded connection hole is opened through the inside of the stirring rod body. The threaded connection rod is threaded into the inside of one end of the threaded connection hole, and a plug is threaded into the other end of the threaded connection hole.
[0019] With the above design, when the stirring rod breaks, the threaded connection end can be disassembled and reinstalled on the threaded connection hole of the longer or neater end after the break, and then the plug can be used to seal the other end of the threaded connection hole.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] 1. The use of a support component in conjunction with the stirring rod not only provides support for the stirring rod but also increases the contact area between the stirring rod and the operator's hand, making it easier to grip the stirring rod and facilitating the stirring operation.
[0022] 2. The support is slidably mounted on the stirring rod. During the sliding process, the solution adhering to the stirring end of the stirring rod can be scraped off, preventing excessive solution from adhering to the stirring rod and dripping onto the work surface. This effectively protects the work surface and avoids waste of solution.
[0023] 3. The use of a scraper combined with a frustum-shaped support allows the scraped solution to flow along the inner wall of the frustum-shaped support and eventually fall into the solution bottle, avoiding splashing caused by direct dripping of the solution; at the same time, when the stirring rod is supported, the remaining solution that is not scraped can drip onto the inner wall of the frustum-shaped support and flow back into the frustum-shaped support, which serves to catch the backflowing solution.
[0024] 4. The scraping ring combined with the scraping edge is used to achieve double scraping and improve the scraping effect;
[0025] 5. The liquid guiding groove and liquid guiding hole are used to avoid the solution from directly contacting the inner wall of the frustum-shaped support body, and to prevent the solution from sticking to the entire stirring rod body when the support body slides back to the threaded connection end position.
[0026] 6. The separate threaded connection end and stirring rod body are adopted, which can be adjusted and installed according to the usage status of the stirring rod body, thus saving costs to a certain extent. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] Example 1:
[0037] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes a stirring rod body 1; one end of the stirring rod body 1 is detachably provided with a threaded connection end 1-1, and a threaded connection rod 8 is integrally formed on one end face of the threaded connection end 1-1. A threaded connection hole 1-2 is provided through the stirring rod body 1. The threaded connection rod 8 is threadedly connected to the inside of one end of the threaded connection hole 1-2. A plug 9 is threadedly connected to the other end of the threaded connection hole 1-2. When the stirring rod body 1 breaks, the threaded connection end 1-1 can be disassembled and reinstalled on the threaded connection hole 1-2 at the longer or neater end after the breakage. Then, the plug 9 is used to seal the other end of the threaded connection hole 1-2.
[0038] It also includes a support member 2; the support member 2 is composed of a connector 3 and a frustoconical support 4; the inner wall of the connector 3 is provided with an internal thread 3-1, and the internal thread 3-1 is detachably connected to the threaded connection end 1-1; the inner diameter of the frustoconical support 4 is larger than the inner diameter of the connector 3, and the two are integrally formed, the inner wall of the connection end of the frustoconical support 4 and the connector 3 forms a scraped edge 5; the support member 2 is threadedly connected to the threaded connection end 1-1, and the support member 2 The slidable sleeve is mounted on the stirring rod body 1; the outer wall of the wide end of the frustoconical support body 4 is provided with several support planes 4-1 to improve the stability during support; several ribs 7 are integrally formed on the support planes 4-1 to increase the friction during support, and at the same time make it easy to hold and avoid slipping during stirring; a scraper ring 6 is detachably connected to the wide end of the frustoconical support body 4 by means of threads, the inner ring wall of the scraper ring 6 is slidably fitted with the outer wall of the stirring rod body 1, and several scraper ring drainage holes 6-1 are opened through the scraper ring 6.
[0039] In this embodiment, the support 2 is fitted onto the end of the stirring rod 1, increasing the contact area between the operator's hand and the stirring rod 1 during stirring, making it easier to grip the stirring rod 1 and facilitating stirring. When stirring stops, first, the entire assembly is positioned vertically above the upper port of the solution bottle, and the support 2 is loosened and removed from the threaded connection end 1-1 of the stirring rod 1, and then slid downwards. During the sliding process, the scraper ring 6 first contacts the solution adhering to the stirring rod 1 and initially scrapes off a portion of the solution. The remaining solution that has not been scraped off by the scraper ring 6 enters through the scraper ring drain hole 6-1. The solution enters the interior of the frustum-shaped support 4 and is scraped again by the scraper edge 5, achieving double scraping. Under its own gravity, the solution drips from the scraper ring drain hole 6-1 into the solution bottle. Finally, the lower end of the stirring rod 1 is placed inside the frustum-shaped support 4, and the whole is placed horizontally, so that the stirring rod 1 is supported on the operating table by the support member 2. The height of the threaded connection end 1-1 of the stirring rod 1 is lower than the supported end of the stirring rod 1 (the end away from the threaded connection end 1-1). A small amount of solution that has not been scraped back along the inner wall of the frustum-shaped support 4 into the interior of the frustum-shaped support 4, avoiding dripping onto the operating table.
[0040] Example 2:
[0041] See Figure 5 and Figure 6As shown, this embodiment is based on embodiment one, and further improves the interior of the frustum-shaped support 4. Specifically, a liquid guiding groove 5-1 is provided in the outward ring direction at the scraping edge 5 position, and a number of liquid guiding holes 4-2 are provided in a ring-shaped manner through the inner wall of the frustum-shaped support 4 at equal angles; a frustum-shaped liquid guiding port 4-3 is provided at one end of the liquid guiding hole 4-2 that is connected to the liquid guiding groove 5-1. The liquid guiding groove 5-1, the frustum-shaped liquid guiding port 4-3 and the liquid guiding hole 4-2 are all connected and arranged. The setting of the frustum-shaped liquid guiding port 4-3 allows the solution to flow into the liquid guiding hole 4-2 more quickly.
[0042] The difference between this embodiment and Embodiment 1 is that a small amount of unscraped solution flows back along the inner wall of the frustum-shaped support 4 to the scraper edge 5, and then flows along the scraper edge 5 into the liquid guide trough 5-1. Under gravity, it enters the liquid guide hole 4-2 and then flows into the solution bottle. This avoids the solution from directly contacting the inner wall of the frustum-shaped support 4 and prevents the solution from sticking to the entire stirring rod 1 during the process of the support 2 sliding back to the threaded connection end 1-1. When stirring is required again, the support 2 can be slid back and tightened onto the threaded connection end 1-1.
[0043] Compared with the prior art, the beneficial effects of the present invention are:
[0044] 1. The use of a support component in conjunction with the stirring rod not only provides support for the stirring rod but also increases the contact area between the stirring rod and the operator's hand, making it easier to grip the stirring rod and facilitating the stirring operation.
[0045] 2. The support is slidably mounted on the stirring rod. During the sliding process, the solution adhering to the stirring end of the stirring rod can be scraped off, preventing excessive solution from adhering to the stirring rod and dripping onto the work surface. This effectively protects the work surface and avoids waste of solution.
[0046] 3. The use of a scraper combined with a frustum-shaped support allows the scraped solution to flow along the inner wall of the frustum-shaped support and eventually fall into the solution bottle, avoiding splashing caused by direct dripping of the solution; at the same time, when the stirring rod is supported, the remaining solution that is not scraped can drip onto the inner wall of the frustum-shaped support and flow back into the frustum-shaped support, which serves to catch the backflowing solution.
[0047] 4. The scraping ring combined with the scraping edge is used to achieve double scraping and improve the scraping effect;
[0048] 5. The liquid guiding groove and liquid guiding hole are used to avoid the solution from directly contacting the inner wall of the frustum-shaped support body, and to prevent the solution from sticking to the entire stirring rod body when the support body slides back to the threaded connection end position.
[0049] 6. The separate threaded connection end and stirring rod body are adopted, which can be adjusted and installed according to the usage status of the stirring rod body, thus saving costs to a certain extent.
[0050] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
