Description

Technical Field

[0001] This application relates to the field of laboratory equipment technology, and in particular to a volumetric flask transfer stand. Background Technology

[0002] Volumetric flasks, as precision measuring instruments in chemical and biological laboratories, play an irreplaceable role in the volume adjustment of sample and standard solutions. Their design characteristics (narrow neck, pear-shaped flat bottom, ground glass stopper, and marking on the neck) determine that the solution volume precisely matches the marked volume only when the concave meniscus of the liquid is tangent to the marking at a specific temperature.

[0003] Currently, volumetric flasks are typically placed in large frames for transport in laboratories. However, due to the shape of volumetric flasks, the following problems often occur during handling: 1. The neck of the volumetric flask breaks due to impact during transport; 2. Using large frames for transport is only suitable for transporting empty volumetric flasks. When the volumetric flask is loaded with liquid, it is very easy for the flask to tip over during normal transport, leading to liquid spillage, sample contamination, or even breakage of the vessel. Utility Model Content

[0004] This utility model provides a volumetric flask transport bracket, which can fix the volumetric flask in place so that it is in an upright position during transport, thus preventing the volumetric flask from breaking or breaking and also preventing the liquid inside the volumetric flask from spilling.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A volumetric flask transfer bracket includes a bottom load-bearing plate, an upper fixing plate, a connecting rod, and a bolt seat;

[0007] The upper fixing plate is provided with a through hole for the bottleneck end of the capacity to pass through, and the upper fixing plate is provided with a through hole; one end of the connecting rod is fixed to the bottom load-bearing plate, and the other end is provided with a threaded groove. The threaded section on the bolt seat passes through the through hole and is screwed to the threaded groove for fixation. The upper fixing plate is fixedly clamped between the upper end of the connecting rod and the bolt seat.

[0008] Preferably, the bottom load-bearing plate is provided with a fixing groove for embedding and fixing the bottom end of the bottle of the appropriate capacity.

[0009] Preferably, the volumetric flask transfer bracket also includes a locking bracket and a fixing seat. The locking bracket includes two U-shaped rods and two crossbars. The bottom ends of the two U-shaped rods are engaged with the fixing seat. The two U-shaped rods are respectively arranged on the outer ends of the volumetric flasks, and the free ends are fixed by the two crossbars.

[0010] Preferably, the crossbar is in close contact with the body of the volumetric flask.

[0011] Preferably, the mounting base has a slot on its side and is made of rubber.

[0012] Preferably, a handle is provided at the upper end of the upper fixing plate.

[0013] Compared with the prior art, the advantages or beneficial effects of the technical solution of this application include:

[0014] 1. By fixing the volumetric flask between the upper fixing plate and the bottom load-bearing plate, a two-way constraint is formed, significantly reducing the risk of tipping. At the same time, the upper fixing plate is provided with a through hole for inserting and fixing the mouth of the volumetric flask, which can prevent the mouth of the volumetric flask from tilting during transportation and causing liquid leakage.

[0015] 2. Each volumetric flask is independently fixed between the upper fixing plate and the bottom load-bearing plate. During transportation, adjacent volumetric flasks will not come into contact or collide, which can greatly reduce the chance of the neck and body of the flask being damaged or broken due to mutual collision, thereby reducing the wear and tear on the experimental instruments.

[0020] The following detailed description of the embodiments of this application, in conjunction with the accompanying drawings, will provide a thorough understanding of how this application uses technical means to solve technical problems and achieve corresponding technical effects, enabling its implementation. The embodiments of this application and the various features within them can be combined with each other without conflict, and all resulting technical solutions are within the protection scope of this application.

[0021] It should be clearly stated that the embodiments described below are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] Example 1: This example provides a detailed description of a solution for a volumetric flask transport support.

[0023] like Figures 1-3 As shown, a volumetric flask transfer bracket includes a bottom support plate 6, an upper fixing plate 2, a connecting rod 9, and a bolt seat 7. The upper fixing plate 2 has a through hole for the neck end of the volumetric flask 1 to pass through, and a through hole. One end of the connecting rod 9 is fixed to the bottom support plate 6, and the other end is provided with a threaded groove 10. The threaded section on the bolt seat 7 passes through the through hole and is screwed to the threaded groove 10. The upper fixing plate 2 is fixedly clamped between the upper end of the connecting rod 9 and the bolt seat 7.

[0024] like Figure 1 The bottom of the volumetric flask 1 is placed on the bottom support plate 6, and the neck of the volumetric flask 1 is through a perforation on the upper fixing plate 2, so that the volumetric flask 1 is always in a vertical position during the transportation process.

[0025] To prevent the volumetric flask 1 from moving during transport, after the neck of the flask is inserted into the perforation, the bolt seat 7 is rotated so that the upper fixing plate 2 is fixedly clamped to the upper end of the connecting rod 9, thereby restricting the movement of the volumetric flask 1.

[0026] like Figure 3 As shown, the bottom support plate 6 is provided with a fixing groove 11 for the bottom end of the volumetric bottle 1 to be embedded and fixed. The function of the fixing groove 11 is to fit the bottom end of the volumetric bottle 1 and maintain the stability of the volumetric bottle 1 during transportation.

[0027] This embodiment also includes a locking bracket and a fixing base 5. The locking bracket includes two U-shaped rods 4 and two crossbars 3. The bottom ends of the two U-shaped rods 4 are engaged with the fixing base 5. The two U-shaped rods 4 are respectively arranged on the outer ends of the volumetric bottle 1, and the free ends are fixed by the two crossbars 3. The crossbars 3 are in close contact with the body of the volumetric bottle 1.

[0028] by Figure 1 and Figure 2 For example, the locking bracket consists of two U-shaped rods 4 and two crossbars 3, both made of thin iron. After the user inserts the two U-shaped rods 4 laterally into the fixing base 5, the lower end of the crossbar 3 can be tightly pressed against the volumetric flask 1, thus further securing the flask. Figure 2 During the above process, the U-shaped rod 4 and the crossbar 3 are flexible and can be pried open by the user and snapped into the fixing seat 5.

[0029] In this embodiment, the fixing base 5 has a slot on its side, and the fixing base 5 is made of rubber. The rubber fixing base 5 has deformation capability, which facilitates the U-shaped rod 4 to be fastened and fixed, and the shape of the slot is like... Figure 3 As shown, once the U-shaped rod 4 is engaged, it is not easy for the U-shaped rod 4 to come out of the slot unless pried out by external force.

[0030] like Figure 1 As shown, a handle 8 is provided at the upper end of the upper fixed plate 2. The handle 8 is mainly used by the user to lift and carry the device, thus facilitating the transfer of the device by the experimental personnel.

[0031] Example 2: Batch transfer of standard solutions to the detection area

[0032] Scenario Description: The lab technician has completed the volumetric dilution of five 100mL volumetric flasks with standard solutions in the standard solution preparation area. These solutions need to be transferred to the spectral detection area 20 meters away for testing, and the journey involves traversing an uneven area.

[0033] Application of the support: Place the five liquid-filled volumetric flasks 1 into the fixing grooves 11 of the bottom support plate of the transfer support, ensuring that the bottom of the flasks is firmly embedded.

[0034] Insert the perforations of the upper fixing plate into the bottleneck of each capacity, and adjust the position to make the bottleneck vertical. Tighten the bolt seat 7 of each bracket unit to firmly clamp the upper fixing plate 2 to the top of the connecting rod 9, forming a bidirectional constraint.

[0035] Insert the bottom ends of the two U-shaped rods 4 into the slots 12 of the rubber fixing base 5, so that the crossbars 4 are close to the middle of the body of each volumetric flask 1, and provide lateral reinforcement by locking the bracket. The experimenter holds the pull handle 8 of the upper fixing plate 2 and lifts the entire bracket for transport smoothly.

[0036] Results:

[0037] 1. During transport, even if the ground is bumpy, the volumetric flask remains upright and there is no liquid spillage.

[0038] 2. Each volumetric flask is independently secured, with no shaking or collision, and the neck and body of the flask are intact.

[0039] 3. Enables safe transfer of multiple samples in a single operation, improving efficiency.

[0040] Example 3: Single-person transport of high-value samples to a sterile room

[0041] Scenario Description: A 250mL volumetric flask containing a valuable biological sample needs to be transferred from the second-floor routine laboratory to the third-floor aseptic operating room, requiring going up and down stairs.

[0042] Application of the support: Place the volumetric flask 1 in the bottom support plate fixing groove 11, and insert the upper fixing plate 2 through the hole into the neck of the flask. Tighten the bolt seat 7 to fix the upper plate, ensuring that the flask is vertical and does not wobble. Install the locking support consisting of the U-shaped rod 4 and the crossbar 3, with the crossbar 3 close to the flask body to increase the anti-tipping ability. The experimenter holds the pull handle 8 with one hand and uses the other hand to help stabilize the support, keeping the support stable when going up and down stairs.

[0043] Results:

[0044] 1. The bottle is not tilted when it turns a corner on the stairs, so there is no risk of leakage of the sample inside the bottle.

[0045] 2. The rubber fixing seat 7 and locking bracket absorb vibration and prevent the bottleneck from breaking due to the vibration of the stairs.

[0046] 3. The pull handle 8 design makes it easy to operate with one hand, making it suitable for moving things in narrow spaces.
