Description

Technical Field

[0001] The invention belongs to the technical field of auxiliary tools for chemical experiments, and in particular relates to an instrument vertical fixing device. Background Art

[0002] When conducting chemical experiments, it is often necessary to build multi-layer experimental systems. Due to their large overall height and complex structure, these systems often have stability issues. To ensure the safe and smooth progress of the experiment, a metal stand and clamps are usually required to fix the experimental system. However, due to the space occupied by the metal stand itself, coupled with the limited space for large instruments such as heating tables and experimental tables, the use of a metal stand and clamps often leads to low utilization of the heating table or the experimental table surface.

[0003] Take condensers, for example. They are widely used in chemical experiments requiring heating. Their primary function is to cool and reflux the vaporized solvent in the experimental vessel, improving solvent efficiency and reducing waste gas emissions. However, because the condenser itself is larger than the reaction vessel and has a longer vertical length when in use, the center of gravity of the entire experimental system is unstable, making it prone to collapse under external forces. This can cause the experiment to terminate, the reaction solution to leak, and even personal injury to the experimenter, posing a safety hazard.

[0004] Currently, the main method for securing condenser tubes is to use a metal stand and a clamp. The condenser tube is fixed with the clamp, and after adjusting the height and position of the stand, the clamp is fixed to the stand. This method mainly fixes the weak link of the experimental system by introducing another relatively stable support structure. Specifically, it relies on the weight of the stand itself and its relatively large support area to form a stable structure.

[0005] Although the above-mentioned fixing method can fix the reaction system using the condenser, in the case where electric heating tables are commonly used in laboratories, due to the limitation of the support area of ​​the iron stand, the number of iron stands that can be placed next to a heating table is limited, the reaction systems that can be supported are small, and the utilization rate of the heating table is low; when a pair of iron stands are used to fix multiple reaction systems, the weight of the fixed object will increase relative to the weight of the iron stand itself, which will reduce the stability of the support and increase the safety risk of the experimental system in this case.

[0006] At the same time, the iron stand placed around the heating table takes up the space of the laboratory table, limits the placement of other experimental equipment, affects the synchronous progress of other experiments, and further reduces the experimental efficiency of the entire laboratory.

[0012] The condenser hanging component comprises a hook portion at the top, a circular collar portion at the lower end and a straight cantilever portion in the middle portion, wherein the two ends of the straight cantilever portion are respectively connected to the hook portion and the circular collar portion, the hook portion is connected to the crossbeam, the circular collar portion has a radius greater than the radius of the condenser tube bundle and less than the distance from the end of the condenser water inlet and the end of the water outlet to the axis of the tube bundle, the circular collar portion has a notch, the size of the notch allows the water inlet and water outlet of the condenser to pass through, so that when the condenser is placed on the circular collar portion, the water inlet and water outlet of the condenser are placed from bottom to top or from top to bottom along the direction of the notch, so that the circular collar portion is sleeved on the outer wall of the tube bundle between the water inlet and the water outlet of the condenser;

[0013] The flask hanging component is installed on the crossbeam and is used for clamping the round bottom flask so that the round bottom flask is located at the lower end of the condenser.

[0014] Furthermore, the circular ring portion has a wrap angle greater than 270°.

[0015] Furthermore, a limiting portion protruding upward is provided at the end of the circular collar portion.

[0016] Furthermore, when the water inlet is located at the upper end of the condenser, the upward protrusion height of the limiting portion is greater than the distance between the circular ring portion and the water inlet of the condenser; when the water outlet is located at the upper end of the condenser, the upward protrusion height of the limiting portion is greater than the distance between the circular ring portion and the water outlet of the condenser.

[0017] Furthermore, the condenser tube hanging component is composed of a load-bearing component and one or more protective layers covering the outside of the load-bearing component.

[0018] Furthermore, the load-bearing components are made of one or more of steel, aluminum, and copper.

[0024] Compared with the prior art, the present invention provides an instrument vertical fixing device, which effectively solves the problems of large space occupation, low laboratory bench utilization and safety caused by the use of iron frames and clamps in traditional chemical experiments by innovatively introducing the design of a crossbeam component and a condenser hanging component. The crossbeam component is installed on two slide rails on the wall of the laboratory bench. Through the adjustability of its structure, it provides a highly flexible and stable support point, allowing experimental instruments to be fixed vertically and reducing the area occupied by the flask hanging component and the laboratory bench. The design of the condenser hanging component enables instruments such as condensers to be safely hung under the crossbeam. At the same time, the clever design of the notch allows the water inlet and outlet of the condenser to pass through conveniently, ensuring the fixation of the condenser without hindering its normal function. In addition, integrating the flask hanging component on the crossbeam component further improves the utilization rate of the experimental space, allowing a single experimental site to support multiple experimental systems at the same time, thereby effectively improving the overall work efficiency and safety of the laboratory.

[0038] The present invention will be described in detail below with reference to the accompanying drawings, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a central component. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] The experimental system support scheme, which uses a metal stand and fixtures, derives its support from the side of the experimental system, that is, parallel to the experimental table. This design is well-reasoned because a stable support surface exists parallel to the experimental table, i.e., the experimental table surface. By gradually establishing stable connections and supports from this plane, stability is easily achieved. However, a laboratory table's vertical space, i.e., the space above the heating table, can also be designed and utilized. Due to the differences in the vertical and parallel properties of the laboratory table, primarily the differences between the crossbeams and the experimental table surface, when utilizing vertical space, suspended support and fixation should be prioritized. Since the height of the experimental system is not a fixed value, it must be adjusted for different experimental systems. For fully fixed support structures, adjustment requires certain height requirements for the experimenter. Therefore, considering the convenience of experimentation—that is, the experimenter can achieve relatively stable experimental results without moving the fixture or with minimal movement—a non-fully fixed structure is necessary.

[0042] In view of the shortcomings of the existing technology, the present invention proposes an instrument vertical fixing device, which aims to improve the fixing method of the multi-layer structure experimental system in the laboratory. Figure 1 、 Figure 2 In the illustrated embodiment, the vertical fixture for the instrument comprises a crossbeam 2, a condenser suspension assembly 3, and a flask suspension assembly 4. The crossbeam 2 consists of two supports 20 and a crossbeam 21 connecting them. Designed to be mounted on rails 10 on either side of a laboratory bench wall 1, its primary function is to provide a stable suspension structure for the instrument. By sliding on the rails 10, the crossbeam 2 can be adjusted to accommodate different experimental instruments or setups.

[0043] like Figure 3 、 Figure 4 As shown, the condenser pipe hanging component 3 is composed of a hook portion 30 at the top, a circular collar portion 31 at the bottom, and a straight cantilever portion 32 connecting the two portions. The two ends of the straight cantilever portion 32 are respectively connected to the hook portion 30 and the circular collar portion 31, wherein the hook portion 30 is used to connect to the crossbeam 21. Figure 5As shown, the radius of the circular collar portion 31 is larger than the radius D1 of the condenser tube bundle 5, and smaller than the distance L from the end of the condenser water inlet 50 and the end of the water outlet 51 to the axis of the tube bundle. In this way, the structure of the water outlet 51 or the water inlet 50 becomes the force point and the fixed point when the condenser 5 is suspended. It can be understood that the arrangement position of the water outlet 51 and the water inlet 50 of the condenser 5 determines which one becomes the force point and the fixed point. When the liquid enters from the bottom and exits from the top, that is, when the water outlet 51 is at the upper end of the condenser 5, the water outlet 51 becomes the force point and the fixed point; when the liquid In from the top and out from the bottom, that is, when the water inlet 50 is at the upper end of the condenser 5, the water inlet 50 becomes a force point and a fixed point, thereby serving the purpose of suspension. When there is no round-bottom flask 6 placed at the bottom of the condenser 5, the condenser hanging component 3 plays the role of hanging the condenser 5. When the condenser 5 is supported and lifted by the round-bottom flask 6 at the bottom, the circular collar portion 31 is in the tube bundle position between the water outlet 51 and the water inlet 50. The role of the condenser hanging component 3 is to prevent the condenser 5 from shaking left and right or tipping over, thereby stabilizing the condenser 5.

[0044] In addition, the circular collar portion 31 is also designed with a notch 301. The size of the notch 301 is based on the fact that the water outlet 51 or the water inlet 50 of the condenser 5 can pass freely. That is, the size of the notch 301 is larger than the diameter D2 (see FIG. Figure 5 The condenser hanging member 3 is designed to secure and stabilize the condenser 5. When the condenser 5 is placed on the circular collar portion 31 through the notch 301, the notch 301 allows the water inlet 50 and outlet 51 of the condenser 5 to pass smoothly through and be installed in the appropriate position, ensuring that the condenser 5 is securely fixed and does not affect its normal use. During the specific fixation, align the water outlet 51 and the water inlet 50 of the condenser 5 with the direction of the notch 301, and place the condenser 5 from top to bottom or from bottom to top toward the circular collar portion 31. When the water outlet 51 of the condenser 5 is on top and is placed from top to bottom, after the circular collar portion 31 is located between the water inlet 50 of the condenser 5 and the water outlet 51 of the condenser 5, rotate the condenser 5 so that the water outlet 51 and the water inlet 50 of the condenser 5 are staggered with the direction of the notch 301, and then continue to place the condenser 5 downward so that the circular collar portion 31 contacts the water outlet 51 of the condenser 5. The water outlet 51 becomes a force point and a fixing point, thereby completing the purpose of hanging the condenser 5.

[0045] The flask hanging component 4 is installed on the crossbeam component 21 and is used to clamp the round-bottom flask 6 so that the round-bottom flask 6 is located at the lower end of the condenser 5. It can be understood that the round-bottom flask 6 serves as the bottom supporting component or fixing component of the condenser 5. The bottom outlet of the condenser 5 is extended into the round-bottom flask 6, or the bottom outlet of the condenser 5 is docked and fixed with the round-bottom flask 6 to complete the support of the condenser 5. Combined with the side support of the condenser hanging component 3, the condenser 5 can be prevented from shaking or tipping over. When the condenser 5 is supported or fixed by the round-bottom flask 6, the circular collar portion 31 is located between the water outlet 51 and the water inlet 50, and may not contact the water outlet 51, but is only sleeved on the outer wall of the tube bundle of the condenser 5. This design effectively saves space on the experimental table and allows the experimenter to configure the experimental device more flexibly, especially in experiments requiring heating reactions.

[0046] The present invention reduces the occupation of the horizontal space of the laboratory table by developing a new type of suspension device that utilizes the space above the laboratory table, and increases the flexibility of adjusting the fixed height through the design of a non-fully fixed device, thereby improving the space utilization rate of the laboratory and the efficiency of experimental work. Specifically, by installing the crossbeam component 2 on the slide rail 10 of the laboratory table wall 1, the occupation of the laboratory table area is reduced, and the utilization rate of the flask suspension component 4 is improved; the design of the crossbeam component 2 and the condenser suspension component 3 ensures the stable fixation of experimental instruments such as the condenser 5, reducing the safety risks caused by the collapse of the instrument; because the crossbeam component 2 can be adjusted on the slide rail 20, the experimenter can adjust the position of the condenser 5 as needed, so that the device can adapt to experimental settings of different positions and types, and improve the flexibility of experimental operations.

[0047] Preferably, the circular collar portion 31 has a wrap angle greater than 270°.

[0048] like Figure 4 As shown, preferably, an upwardly protruding limit portion 302 is provided at the end of the circular ring portion 31 to prevent the condenser 5 from slipping from the notch 301 when it rotates. It should be noted that when the condenser hanging component 3 suspends the condenser 5 (that is, the round-bottom flask at the bottom is taken away), when the water outlet is located at the upper end of the condenser 5, the upward protruding height of the limit portion 302 is preferably greater than D2.

[0049] like Figure 6 As shown, preferably, the condenser suspension component 3 adopts a design in which a load-bearing component 3001 is covered with one or more protective layers 3002.

[0050] Preferably, the load-bearing member 3001 is made of a rigid material with a certain processing toughness.

[0051] Preferably, the load-bearing member 3001 is made of one or more of steel, aluminum, copper or their alloy steels, and is a single linear structure, and is covered with a protective layer 3002 before being manufactured into the desired state.

[0052] Preferably, the material of the protective layer 3002 can be made of one or more of polyethylene, polypropylene, silicone material, and rubber material, and the protective layer 3002 is formed on the surface of the above-mentioned load-bearing component 3001 by an extrusion coating process.

[0053] Preferably, the load-bearing member 3002 can also be made of one or more of polyethylene, polypropylene, nylon, polycarbonate, polyethylene terephthalate, polybutylene terephthalate, polylactic acid and their modified products, and manufactured into the desired state using an injection molding process. In this case, no additional protective layer 3002 is required.

[0054] like Figure 1 As shown, preferably, the flask hanging component 4 also includes a cross fastener 40, a long rod 41, a cross fastener 242 and a clamp 43. The cross fastener 40 is used to fix the long rod 41 to the cross beam 21 in a vertical direction. This design allows the long rod 41 to be firmly connected to the cross beam component 2, providing a stable support base for the next step of the device, while allowing the long rod 41 to be adjusted in the vertical direction to adapt to heating requirements of different heights. One end of the clamp 43 is designed to clamp the round-bottom flask 44, while the other end is connected to the long rod 41 in a vertical direction through the cross fastener 242. The main function of the clamp 43 is to fix the round-bottom flask 44 and ensure the stability of the round-bottom flask 44 during the heating process. By adjusting the lateral position of the clamp 43 on the long rod 41, the user can adjust the position of the round-bottom flask 44 according to the experimental requirements so that it is directly below the condenser 5.

[0055] It should be noted that the cross fastener 1 40 and the cross fastener 2 42 are also known as right-angle fasteners, which are commonly used connecting components for connecting two vertical cross pipes.

[0056] Preferably, the clamp 43 in the hanging and fixing solution includes but is not limited to a test tube clamp, a flask clamp, a burette clamp, a single-arm clamp, a butterfly clamp and a cross clamp.

[0057] like Figure 4 As shown, the crossbeam 21 is placed on the slide rail 10 of the laboratory table wall 1 (refer to Figure 2 ), the condenser hanging component 3 is fixed on the crossbeam 21 through the hook part 30, and the condenser 5 is inserted into the circular ring part 31 of the condenser hanging component 3. Pay attention to place the water outlet 51 or water inlet 50 of the condenser 5 on the part with the load-bearing structure on the circular ring part 31, so that it can hang freely. The condenser 5 is dragged by the condenser hanging component 3 and will not fall even if it is shaken left and right.

[0058] like Figure 5 As shown, the crossbeam 21 is placed on the slide rail 10 of the laboratory table wall 1 (refer to Figure 2 ), take any rigid long rod 41 and vertically secure it to the crossbeam 21 using cross fastener 1 40. Secure a round-bottom flask 44 with a flask clamp, adjust the height, and secure it to the rigid long rod 41 using cross fastener 2 42. Take a spherical condenser 5 and suspend it from the crossbeam 21 using the condenser suspension component 3.

[0059] During the experiment, move the crossbeam 21 to directly above the round-bottom flask 44 and adjust the condenser hanging component 3 to align the condenser 5 with the round-bottom flask 44 to be matched. Then adjust the height of the round-bottom flask 44 until the condenser 5 is connected to the round-bottom flask 44 below. If necessary, adjust the position of each instrument to achieve the most stable state of the system.

[0060] The present invention mainly addresses the problem of insufficient utilization of laboratory space. It utilizes or improves the beam structure of the laboratory table itself, designs a ring-type suspension device that can provide support for laboratory equipment in the vertical direction, and combines it with existing laboratory equipment to develop and utilize the space above the laboratory table.
