Description

Technical Field

[0001] This utility model relates to the field of reagent stirring technology, and in particular to a locking device for stirring reagent bottles. Background Technology

[0002] Existing vacuum degassing equipment typically has a fixed-size stirring drum, which can only be locked with specific fixtures. However, most methods of locking reagent bottles involve clamping rubber rings. After prolonged use, the rubber rings wear out and are difficult to replace, causing the reagent bottles to loosen and affecting the stirring effect.

[0003] For example, publication number "CN223361835U" discloses "a reagent sampling device for a protein analyzer," which includes a support base, a rotating shaft rotatably mounted on the support base, a rotation drive mechanism, a reagent placement tray sleeved on the rotating shaft, and a reagent limiting tray positioned above the reagent placement tray. The reagent placement tray has multiple outer ring placement slots arranged circumferentially along the rotating shaft, and reagent bottles are arranged circumferentially in the corresponding outer ring placement slots. However, in practical applications, because such reagent bottles cannot be effectively locked and stabilized, it affects the subsequent stirring process. Utility Model Content

[0004] In view of the problem mentioned in the background art that the reagent bottle cannot be effectively locked during the stirring process, the present invention provides a locking device for stirring reagent bottles, which can lock the reagent bottle and adjust the locking force as needed to ensure the stability of the reagent bottle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A locking device for stirring a reagent bottle includes a fixed base with a mounting groove for placing the reagent bottle. A locking cavity is connected to the mounting groove, and a locking element is threaded onto the locking cavity. An adjustment groove is provided between the locking cavity and the mounting groove, and an elastic ring is provided in the adjustment groove. The locking element abuts against and can compress the elastic ring. When the reagent bottle is placed in the mounting groove, the elastic ring surrounds the reagent bottle. Existing vacuum degassing machines typically have a fixed-size stirring drum, requiring specific fixtures to lock reagent bottles. However, most methods rely on clamping rubber rings, which wear down over time and are difficult to replace, causing the bottles to loosen and affecting the stirring effect. Since different batches of reagent bottles may have slight dimensional variations, relying solely on the elasticity of the rubber rings for self-adaptation results in inconsistent locking, leading to some bottles failing to lock properly and becoming loose, thus impacting subsequent stirring quality. Therefore, to address these issues, this application provides a mounting groove on the mounting base, capable of accommodating the reagent bottle with a clearance fit. A locking cavity is provided within the mounting groove, allowing for the connection of a locking element. An adjustment groove is provided between the locking cavity and the mounting groove, featuring a spring-loaded mechanism. The locking ring, or elastic ring, is capable of elastic expansion and contraction, and includes, but is not limited to, deformable elastic materials such as rubber rings and resin rings. Because the locking cavity and locking element are connected by a thread, the locking element can move up and down during forward and reverse rotation. Since the locking element abuts against the elastic ring, this up-and-down movement creates varying degrees of compression on the elastic ring, causing it to expand to different degrees. By applying different elastic forces to the reagent bottle through the elastic ring, the reagent bottle is secured. Because the elastic force applied by the elastic ring can be adjusted by the locking element, even with manufacturing errors in individual reagent bottles, the varying degrees of compression from the elastic ring ensure a stable locking effect, preventing loosening and guaranteeing the stability of the reagent bottles during subsequent stirring.

[0007] Preferably, the locking cavity includes a cavity sidewall with a fixing thread that is threadedly connected to the locking member. A limiting step is provided at the end of the cavity sidewall near the mounting groove, allowing the locking member to abut against the limiting step during locking. The locking cavity includes a cavity sidewall with a fixing thread that is threadedly connected to the locking member. A limiting step is provided below the cavity sidewall, and this limiting step has an inwardly recessed structure. During the locking process, if the locking member continues to tighten and descend, it will abut against the limiting step, thus preventing the locking member from continuously applying pressure to the elastic element to its limit position, ensuring the service life of the elastic element, and also avoiding excessive pressure on the reagent bottle.

[0008] Preferably, the locking component includes a threaded area that is threadedly connected to the locking cavity, and a polygonal screw cap is connected to the end of the threaded area away from the mounting groove. The locking component has a threaded area that is threadedly connected to the locking cavity, and a polygonal screw cap is provided above the threaded area. The polygonal screw cap has several planar structures to facilitate screwing, improve anti-slip effect, and reduce the probability of slipping during screwing.

[0009] Preferably, the locking member has an inner opening, with a portion of the reagent bottle located within this opening. The inner opening is positioned in the central area of ​​the locking member. After the reagent bottle is placed in the mounting groove, the locking member is threaded into the locking cavity. At this point, the inner opening aligns with the reagent bottle. After installation, the reagent bottle is partially positioned within the inner opening, creating a structure where the upper part of the reagent bottle is within the inner opening, the lower part is within the mounting groove, and the middle part abuts against the elastic ring. This improves the stability of the reagent bottle. Furthermore, to ensure smooth installation of the reagent bottle and to reduce wear, the reagent bottle is clearance-fitted with both the inner opening and the mounting groove.

[0010] Preferably, a support ring is provided at the bottom of the mounting groove, and the support ring has a bottom opening at its center. The support ring abuts against the bottom of the reagent bottle. The support ring at the bottom of the mounting groove supports the reagent bottle, and the bottom opening at its center allows it to contact the bottom of the reagent bottle. During the removal of the reagent bottle, it can be pushed upwards through the bottom opening, thus allowing for stable and quick removal.

[0011] Preferably, the base has a raised sidewall at its bottom, and the base has a hollow cavity inside the raised sidewall. The combination of the raised sidewall and the hollow cavity allows for better adaptation to the installation position of the mixer, enabling the mixer to better connect with the locking device and improving mixing stability.

[0012] Preferably, the hollow cavity is connected to the bottom opening. Connecting the hollow cavity to the bottom opening allows the reagent bottle to be lifted upwards through both the hollow cavity and the bottom opening.

[0013] Preferably, the outer wall of the fixing base is provided with a plurality of outwardly extending ring plates, and a mating notch is provided between each of the outwardly extending ring plates. The outwardly extending ring plates on the outer wall of the fixing base allow for mating with the mixer, and the mating notch between each outwardly extending ring plate ensures that the locking device can be better adapted and connected to the mixer, improving the stability of the locking device and the reagent bottle during subsequent rotation.

[0014] Preferably, the locking member includes a locking portion located within a locking cavity. The locking portion has a pressing portion at its end near the mounting groove, which can be embedded into an adjusting groove. The pressing portion abuts against and compresses the elastic ring. The locking member is threadedly connected to the locking cavity via the locking portion. The pressing portion, located within the adjusting groove, abuts against the elastic ring during the up-and-down movement of the locking portion, allowing the pressing portion to displace relative to the elastic ring during adjustment, thereby causing the rubber ring to expand to varying degrees.

[0015] Preferably, the squeezing part is an annular protrusion at the end of the locking part. When the squeezing part is located in the adjusting groove, it forms a semi-enclosed structure with the opening facing the reagent bottle. The squeezing part, being an annular protrusion at the end of the locking part, can uniformly and stably squeeze the elastic ring. Furthermore, because a semi-enclosed structure is formed between the squeezing part and the adjusting groove, and the opening is positioned facing the reagent bottle, the expansion of the elastic ring can be directed towards one side of the reagent bottle, ensuring that the elastic force is stably applied within the reagent bottle.

[0016] The beneficial effects of this utility model are as follows: (1) Through the threaded connection between the locking part and the locking cavity, the elastic ring can be squeezed to different degrees, so that the elastic ring can apply elastic force to the reagent bottle, thereby adapting to the reagent bottle with processing error and avoiding the phenomenon of loosening due to the self-adaptation of the elastic ring alone; (2) A support ring and a bottom opening are provided at the bottom of the mounting slot to facilitate the removal of reagent bottles and improve the smoothness and efficiency of operation; (3) By raising the side wall and hollow cavity, extending the ring plate and the docking notch, the locking device can be more stably adapted to the stirring device, thereby improving the stability during the stirring process.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: like Figure 1 , 2 As shown, a locking device for stirring a reagent bottle includes a fixed base 1, a mounting groove 11 for placing a reagent bottle 2 on the fixed base 1, a locking cavity 12 connected to the mounting groove 11, a locking member 3 threadedly connected to the locking cavity 12, an adjusting groove 13 between the locking cavity 12 and the mounting groove 11, an elastic ring 14 disposed in the adjusting groove 13, the locking member 3 abuts against and can compress the elastic ring 14, and when the reagent bottle 2 is placed in the mounting groove 11, the elastic ring 14 surrounds the reagent bottle 2. Existing vacuum degassing machines typically have a fixed-size stirring drum, requiring specific fixtures to lock the reagent bottle 2. However, most methods of locking the reagent bottle 2 involve clamping a rubber ring. Over time, this rubber ring wears down and is difficult to replace, causing the reagent bottle 2 to loosen and affecting the stirring effect. Since different batches of reagent bottles 2 may have slight dimensional variations, relying solely on the elasticity of the rubber ring for self-adaptation will result in inconsistent locking effects between the bottles, leading to some bottles failing to lock properly and becoming loose, thus affecting subsequent stirring quality. Therefore, to address these issues, this application provides a mounting groove 11 on the fixed base 1. The mounting groove 11 accommodates the reagent bottle 2 with a clearance fit. A locking cavity 12 is provided on the mounting groove 11, and a locking element 3 can be connected to the locking cavity 12. An adjusting groove 13 is provided between the locking cavity 12 and the mounting groove 11, and an elastic ring is provided on the adjusting groove 13. 14. The elastic ring 14 is capable of elastic expansion and contraction, including but not limited to deformable elastic materials such as rubber rings and resin rings. Since the locking cavity 12 and the locking member 3 are connected by threads, the locking member 3 can move up and down during the forward and reverse rotation of the locking cavity 12. Because the locking member 3 abuts against the elastic ring 14, the elastic ring 14 can be squeezed to different degrees during the lifting and lowering of the locking member 3, thereby causing the elastic ring 14 to expand to different degrees. Different elastic forces are applied to the reagent bottle 2 by the elastic ring 14, thereby achieving the fixing effect of the reagent bottle 2. Since the elastic force applied by the elastic ring 14 can be adjusted by the locking member 3, even if there are processing errors in each reagent bottle 2 during use, the different degrees of compression by the elastic ring 14 can achieve a stable locking effect on each reagent bottle 2, preventing the reagent bottle 2 from becoming loose and ensuring the stability of the reagent bottle 2 during subsequent stirring.

[0023] like Figure 2 , 3 As shown, the locking cavity 12 includes a cavity sidewall 15, on which a fixing thread 151 is provided for threaded connection with the locking member 3. A limiting step 16 is provided at one end of the cavity sidewall 15 near the mounting groove 11, and the locking member 3 can abut against the limiting step 16 during the locking process. The locking cavity 12 includes a cavity sidewall 15, on which a fixing thread 151 is provided, and the fixing thread 151 is threadedly connected with the locking member 3. A limiting step 16 is provided below the cavity sidewall 15, wherein the limiting step 16 has an inward structure and is located below the fixing thread 151. During the locking process of the locking member 3, if the locking member 3 continues to tighten and descend, it will abut against the limiting step 16, thereby preventing the locking member 3 from continuously applying pressure to the elastic member to the limit position, ensuring the service life of the elastic member, and also preventing excessive squeezing force on the reagent bottle 2.

[0024] like Figure 2 , 3 As shown, the locking component 3 includes a mating threaded area 311 that is threadedly connected to the locking cavity 12. A polygonal screw cap 32 is connected to the end of the mating threaded area 311 away from the mounting groove 11. The locking component 3 is provided with a mating threaded area 311, which is threadedly connected to the locking cavity 12. A polygonal screw cap 32 is provided above the mating threaded area 311. The polygonal screw cap 32 is provided with several planar structures to facilitate screwing, improve the anti-slip effect, and reduce the probability of slipping during screwing.

[0025] like Figure 2 , 3 As shown, the locking member 3 is provided with an inner opening 33, and the reagent bottle 2 is partially located in the inner opening 33. The inner opening 33 is provided on the locking member 3, and the inner opening 33 is located in the central area of ​​the locking member 3. After the reagent bottle 2 is placed in the mounting groove 11, the locking member 3 is threadedly connected to the locking cavity 12. At this time, the inner opening 33 aligns with the reagent bottle 2. After installation, the reagent bottle 2 will be partially located in the inner opening 33, forming a structure in which the upper part of the reagent bottle 2 is located in the inner opening 33, the lower part is located in the mounting groove 11, and the middle position abuts against the elastic ring 14, thereby improving the stability of the reagent bottle 2. Furthermore, in order to ensure the smooth installation of the reagent bottle 2 and to reduce wear, the reagent bottle 2, the inner opening 33, and the mounting groove 11 are all clearance fit.

[0026] like Figure 2As shown, a support ring 17 is provided at the bottom of the mounting groove 11. The support ring 17 has a bottom opening 171 at its center and abuts against the bottom of the reagent bottle 2. The support ring 17 at the bottom of the mounting groove 11 supports the reagent bottle 2. The bottom opening 171 at the center of the support ring 17 allows it to contact the bottom of the reagent bottle 2. During the removal of the reagent bottle 2, it can be pushed upward through the bottom opening 171, thus allowing the reagent bottle 2 to be removed stably and quickly.

[0027] like Figure 2 , 3 As shown, the locking member 3 includes a locking part 31 located within the locking cavity 12. A pressing part 34, which can be embedded into the adjusting groove 13, is provided on the end of the locking part 31 near the mounting groove 11. The pressing part 34 abuts against and presses the elastic ring 14. The locking member 3 is threadedly connected to the locking cavity 12 via the locking part 31. The pressing part 34 abuts against the elastic ring 14 and is located within the adjusting groove 13, allowing the pressing part 34 to move relative to the elastic ring 14 during the up-and-down movement of the locking part 31, thereby causing the rubber ring to expand to different degrees.

[0028] like Figure 2 As shown, the squeezing part 34 is an annular protrusion at the end of the locking part 31. When the squeezing part 34 is located in the adjusting groove 13, the squeezing part 34 and the adjusting groove 13 form a semi-enclosed structure with the opening facing the reagent bottle 2. The squeezing part 34 is an annular protrusion provided at the end of the locking part 31. The annular protrusion can uniformly and stably squeeze the elastic ring 14. Since the squeezing part 34 and the adjusting groove 13 form a semi-enclosed structure and the opening is set to face the reagent bottle 2, the expansion of the elastic ring 14 can face the reagent bottle 2, ensuring that the elastic force can be stably applied to the reagent bottle 2.

[0029] Example 2: like Figure 3 As shown, the bottom of the fixing base 1 is provided with a raised sidewall 18, and a hollow cavity 181 is formed inside the raised sidewall 18. The raised sidewall 18 at the bottom of the fixing base 1, with the hollow cavity 181 inside, allows for better adaptation to the installation position of the mixer, enabling the mixer to better connect with the locking device and improve the stability of the mixing.

[0030] like Figure 3 As shown, the hollow cavity 181 is connected to the bottom opening 171. By connecting the hollow cavity 181 to the bottom opening, the reagent bottle 2 can be lifted upwards through the hollow cavity 181 and the bottom opening 171.

[0031] like Figure 3 As shown, the outer wall of the fixing base 1 is provided with several outwardly extending ring pieces 19, and a docking notch 191 is provided between each outwardly extending ring piece 19. The outwardly extending ring pieces 19 on the outer wall of the fixing base 1 can dock with the mixer, and the docking notch 191 between each outwardly extending ring piece 19 allows the locking device to be better adapted and connected with the mixer, improving the stability of the locking device and the reagent bottle 2 during subsequent rotation.

The locking cavity 12 includes a cavity sidewall 15. A fixing thread 151 is provided on the cavity sidewall 15, which is threadedly connected to the locking member 3. A limiting step 16 is provided at the end of the cavity sidewall 15 near the installation groove 11. The locking member 3 can abut against the limiting step 16 during locking. The locking member 3 includes a mating thread area 311 threadedly connected to the locking cavity 12. A polygonal screw cap 32 is connected to the end of the mating thread area 311 away from the installation groove 11. The locking member 3 has an inner opening 33, and the reagent bottle 2 is partially located in the inner opening 33.

When the pressing part 34 is located in the adjustment groove 13, the pressing part 34 and the adjustment groove 13 form a semi-enclosed structure with the opening facing the reagent bottle 2.

[0033] The assembly and operation process of the locking device for the reagent bottle stirring in this embodiment is as follows: In this embodiment, the fixing base 1, reagent bottle 2, and locking component 3 are all cylindrical structures.

A locking cavity 12 is provided on the side of the adjustment groove 13 away from the mounting groove 11. A limiting step 16 is formed between the locking cavity 12 and the adjustment groove 13. An elastic ring 14 is installed on the adjustment groove 13. In this embodiment, the elastic ring 14 is made of rubber. A fixing thread 151 is provided on the cavity sidewall 15 of the mounting cavity. A locking member 3 is connected inside the mounting cavity.
