[0027] 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.
[0028] The purpose of this invention is to provide a safety iron stand for chemical experiments to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively ensures stability during use, and effectively improves operational convenience and experimental efficiency.
[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] This utility model provides a safety iron stand for chemical experiments, such as... Figures 1-7 As shown, the system includes: a frame assembly 1, an adjustment assembly 2, and a storage component 3. The frame assembly 1 includes a base 101, a counterweight, and a column 102. The bottom surface of the base 101 has a recessed structure to form a counterweight installation position. The counterweight is detachably and fixedly connected to the counterweight installation position. The column 102 is vertically and fixedly connected to the top surface of the base 101. One end of the adjustment assembly 2 is slidably connected to the column 102 and can maintain its slidable position. The adjustment assembly 2 can extend or retract and maintain its extended or retracted position. The storage component 3 is detachably and fixedly connected to the end of the adjustment assembly 2 away from the column 102. The recessed structure of the base 101 forms a counterweight installation position, facilitating the installation and removal of the counterweight. The detachable counterweight connection allows for the addition or removal of counterweights as needed in different usage scenarios, enhancing device stability or facilitating portability. The column 102 is vertically fixed to the top surface of the base 101, providing stable and vertical support for the adjustment component 2 and the placement component 3, ensuring the overall stability of the iron stand structure and facilitating subsequent support and operation of experimental items. The sliding connection between the adjustment component 2 and the column 102, along with its ability to maintain its sliding position, allows for flexible adjustment of the height of the adjustment component 2 on the column 102 to adapt to the height requirements of different experimental devices. The extension and retraction of the adjustment component 2, along with its fixed position after extension, changes the distance between the placement component 3 and the column 102, meeting diverse positional adjustment needs in different experimental operations and making experimental operations more convenient and precise. The detachable and fixed connection between the placement component 3 and the adjustment component 2 facilitates quick replacement of different types of placement components 3 according to different experimental needs, eliminating the need for complex installation steps, improving the versatility and efficiency of the iron stand, and adapting to various chemical experimental scenarios.
[0031] In a preferred embodiment, a sealing cap is also included. The counterweight is a water tank 103, with a water inlet pipe at the top of the water tank 103 and a water inlet 104 on the top surface of the base 101. The water tank 103 and the base 101 are detachably and fixedly connected, and the water inlet pipe is connected to and communicates with the water inlet 104. The sealing cap is used to close or open the water inlet 104. Using the water tank 103 as a counterweight, the weight of the lower part of the iron frame can be increased by filling with water, thus lowering the center of gravity and improving stability. The detachable connection method allows the water tank 103 to be removed or drained when not in use or when being carried, reducing weight. The sealing cap can control the opening and closing of the water inlet 104. It opens when filling with water and seals when full to prevent water overflow, ensuring stable operation of the device and a clean working environment.
[0032] In a preferred embodiment, the adjustment component 2 includes a sliding member and a telescopic member. The sliding member is detachably and fixedly connected to the column 102. One end of the telescopic member is fixedly connected to the sliding member, and the other end is detachably and fixedly connected to the placement member 3. The adjustment component 2 is divided into a sliding member and a telescopic member. The detachable and fixed connection between the sliding member and the column 102 facilitates height adjustment. The telescopic member connects the sliding member and the placement member 3. The position of the placement member 3 can be changed by telescoping, and the detachable connection facilitates component replacement and maintenance, making the adjustment more flexible and maintenance more convenient.
[0033] In a preferred embodiment, the sliding member includes a clamping member 201 and a fixing screw 203. The clamping member 201 is used to be sleeved on the outside of the column. A first threaded hole is provided on one side of the clamping member 201. The fixing screw 203 is used to be threaded into the threaded hole, and one end of the fixing screw 203 passes through the threaded hole and presses against the column. By sleeved on the outside of the column 102 with the clamping member 201 and then threadedly connected and pressed against the column 102 with the fixing screw 203, this connection method is simple and reliable, and can quickly fix the sliding member on the column 102. Moreover, the position of the sliding member on the column 102 can be flexibly adjusted by loosening or tightening the fixing screw 203 to meet the height adjustment requirements of different experiments.
[0034] In a preferred embodiment, the clamping member 201 is a groove-shaped member. The first side plate of the groove-shaped member is provided with a first threaded hole, and the second side plate of the groove-shaped member is provided with an arc-shaped member. The arc-shaped member is used to fit against the column 102. The design of the groove-shaped member facilitates installation and disassembly. The first threaded hole is used to install the fixing screw 203. The arc-shaped member of the second side plate fits against the column 102, which increases the contact area between the clamping member 201 and the column 102, improves the stability of clamping, ensures that the adjusting component 2 will not easily shake during use, and improves the overall stability and reliability of the iron frame.
[0035] In a preferred embodiment, the telescopic member includes a first hinge, a second hinge, a first adjusting member 206, a second adjusting member, a driving member, a first connecting rod 205, a second connecting rod, a third connecting rod, and a fourth connecting rod. The first hinge is fixedly connected to the end of the slotted member away from the first threaded hole. One end of the first connecting rod 205 is hinged to the first hinge, and the other end is hinged to the first adjusting member 206. One end of the second connecting rod is hinged to the first hinge, and the other end is hinged to the second adjusting member. One end of the third connecting rod is hinged to the first adjusting member 206, and the other end is hinged to the second hinge. The fourth connecting rod... One end of the drive component is hinged to the second adjusting member, and the other end is hinged to the second hinge member 202. The second hinge member 202 is used to detachably fix the object 3. One end of the drive component is connected to the first adjusting member 206, and the other end is connected to the second adjusting member to drive the first adjusting member 206 and the second adjusting member to move closer or further apart, thereby causing the first hinge member 204 and the second hinge member 202 to move closer or further apart. By driving the first adjusting member 206 and the second adjusting member to move, the distance between the first hinge member and the second hinge member can be precisely adjusted, thereby accurately changing the distance between the object 3 and the column 102. The hinged connections between the components ensure the flexibility of the structure, making the adjustment process smoother and meeting the requirements of different experiments for precise adjustment of the position of the object 3.
[0036] In a preferred embodiment, the first link 205, the second link, the third link, and the fourth link are arranged in a rhomboid pattern. This rhomboid distribution makes the structure more stable and symmetrical. When the driving component pushes the first adjusting component 206 and the second adjusting component to move, it can evenly transmit force, ensuring smooth and accurate adjustment of the distance between the first hinge and the second hinge. This stable structure can reduce deviations during the adjustment process, further improving the accuracy and reliability of the iron frame adjustment.
[0037] In a preferred embodiment, the driving component is a bidirectional screw 207. A first adjusting component 206 has a first threaded hole, and a second adjusting component has a second threaded hole. The two ends of the bidirectional screw 207, with opposite rotation directions, are threadedly connected to the first and second threaded holes, respectively. The design of the bidirectional screw 207 allows rotation of the bidirectional screw 207 to simultaneously drive the first adjusting component 206 and the second adjusting component closer together or further apart. The threaded connection has self-locking properties, reliably fixing the positions of the first adjusting component 206 and the second adjusting component after adjustment, thereby stably maintaining the position of the object 3 and preventing positional changes due to component loosening during the experiment, ensuring the smooth progress of the experiment.
[0038] In a preferred embodiment, both the drive end of the bidirectional screw 207 and the drive end of the fixing screw 203 are provided with handles. These handles facilitate operation of the bidirectional screw 207 and the fixing screw 203. The handles allow for easier rotation of the bidirectional screw 207 to adjust the length of the telescopic component and tightening or loosening of the fixing screw 203 to adjust the position of the sliding component. This reduces operational difficulty, improves ease of use and efficiency, and enables researchers to adjust the device more quickly and accurately.
[0039] In a preferred embodiment, the device further includes a first guide tube 2010, a first guide rod 2011, a second guide tube, and a second guide rod. One end of the first guide tube 2010 is fixedly connected to the first hinge member 204. One end of the first guide rod 2011 is sleeved on the first guide tube 2010, and the other end is fixedly connected to the first hinge member 204. One end of the second guide tube is fixedly connected to the first hinge member 204, and one end of the second guide rod is sleeved inside the second guide tube, and the other end is fixedly connected to the second hinge member 202. The guide tubes and guide rods provide guidance for the movement of the telescopic member. The cooperation of the first guide tube 2010, the first guide rod 2011, the second guide tube, and the second guide rod ensures that the first and second hinge members maintain linear movement during the movement, avoiding deviation or wobbling, further improving the stability and accuracy of the telescopic adjustment, and ensuring accurate and reliable position adjustment of the object 3.
[0040] In a preferred embodiment, the system further includes a first limiting screw 2013 and a second limiting screw. The first guide tube 2010 has a first elongated hole 2012, and the first guide rod 2011 has a second threaded hole. One end of the first limiting screw 2013 passes through the first elongated hole 2012 and is threadedly connected to the second threaded hole, and can pass through the second threaded hole to press against the inner wall of the first guide tube 2010. The second guide tube has a second elongated hole, and the second guide rod has a third threaded hole. One end of the second limiting screw passes through the second elongated hole and is threadedly connected to the third threaded hole, and can pass through the third threaded hole to press against the inner wall of the second guide tube. The first limiting screw 2013 and the second limiting screw can respectively fix the positions of the first guide rod 2011 and the second guide rod within the guide tube. During adjustment, by turning the first limiting screw 2013 and the second limiting screw, the guide rod can move inside the guide tube. After adjustment, by tightening the limiting screws, the positions between the guide tube and the guide rod are relatively fixed, increasing stability during use. This further enhances the stability and safety of the iron frame adjustment structure.
[0041] In a preferred embodiment, the device further includes a threaded rod 208 and a locking nut 209. A threaded tube 4 is provided on one side of the device 3. One end of the threaded rod 208 is fixedly connected to the end of the second hinge 202 away from the first hinge 204, and the other end is used for threaded connection with the threaded tube 4. The locking nut 209 is threadedly connected to the threaded rod 208 and can press the threaded tube 4. The threaded connection between the threaded rod 208 and the threaded tube 4 realizes a reliable connection between the device 3 and the telescopic component, which facilitates the replacement of different devices 3. The locking nut 209 can further press the threaded tube 4 after connection to prevent the device 3 from loosening due to vibration or other reasons during the experiment, ensuring that the device 3 remains stable during use and improving the reliability of the experimental operation.
[0042] In a preferred embodiment, the support element 3 is one of the following: an iron ring, a flask clamp, a burette clamp, a condenser clamp, or an iron clip. Multiple types of support elements 3 are available, making the iron stand widely applicable and able to meet the needs of supporting and securing experimental equipment in various chemical experiments. Users can quickly replace the required support element 3 according to the specific experimental content, improving the flexibility and versatility of the iron stand and enabling it to function in various experimental scenarios.
[0043] The present invention provides a method for using a safety iron stand for chemical experiments.
[0044] Preparation stage
[0045] Install the counterweight: Depending on actual usage needs, if it is necessary to increase the stability of the iron stand, align the water tank 103 (counterweight) with the water inlet 104 on the top surface of the base 101 via the water inlet pipe and make a detachable and fixed connection. If water needs to be added, open the sealing cap and add water to the water tank 103 through the water inlet 104. After adding water, replace the sealing cap. If it is not necessary to add weight or if it is necessary to carry the iron stand, the water tank 103 can be removed or drained before removal.
[0046] Install adjustment component 2
[0047] Determine the height: Place the clamping part 201 (slot-shaped part) on the outside of the column 102. By rotating the fixing screw 203 (with a handle on the drive end), the fixing screw 203 passes through the first threaded hole on the clamping part 201 and presses against the column 102. At this time, the position of the sliding part (composed of the clamping part 201 and the fixing screw 203) on the column 102 can be adjusted and fixed according to the required height of the experiment.
[0048] Preparation for telescopic adjustment: Regarding the telescopic components, the first link 205, second link, third link, and fourth link are arranged in a diamond shape, and the first hinge is fixedly connected to the end of the slotted component furthest from the first threaded hole, thus the basic installation is complete. However, before use, it is necessary to confirm whether the hinges between each link are flexible.
[0049] Install the device 3: Select a suitable device 3 (such as an iron ring, flask clamp, etc.) according to the experimental requirements. Thread the threaded tube 4 on one side of the device 3 to one end of the threaded rod 208. Fix the other end of the threaded rod 208 to the end of the second hinge 202 away from the first hinge 204. Then use the locking nut 209 to thread the threaded rod 208 and press the threaded tube 4 to ensure that the device 3 is installed firmly.
[0050] Experimental phase
[0051] Height adjustment: If the height of the object 3 needs to be adjusted during the experiment, simply loosen the fixing screw 203, slide the slider up and down to the appropriate position, and then tighten the fixing screw 203. No other parts need to be disassembled, making the operation simple.
[0052] Distance Adjustment: When it is necessary to change the distance between the placement component 3 and the column 102, rotate the bidirectional screw 207 (with a handle at the drive end). The two ends of the bidirectional screw 207, rotating in opposite directions, are threadedly connected to the first threaded hole on the first adjusting component 206 and the second threaded hole on the second adjusting component, respectively. As the bidirectional screw 207 rotates, the first adjusting component 206 and the second adjusting component will move closer or further apart. Through the linkage of the first connecting rod 205, the second connecting rod, the third connecting rod, and the fourth connecting rod, the first hinge component 204 and the second hinge component 202 will also move closer or further apart, thereby adjusting the distance between the placement component 3 and the column 102. During the adjustment process, the first guide tube 2010, the first guide rod 2011, the second guide tube, and the second guide rod will play a guiding role to ensure smooth and accurate adjustment; the first limit screw 2013 and the second limit screw can limit the movement range of the guide rod within the guide tube to prevent over-adjustment.
[0053] End Phase
[0054] Disassembling the storage component 3: After the experiment, first loosen the locking nut 209 and remove the storage component 3 from the threaded rod 208 for future use or to replace other storage components 3.
[0055] Remove the counterweight (if necessary): If water tank 103 is installed as a counterweight, to reduce the weight or facilitate storage, the sealing cap can be opened to drain the water from water tank 103, and then water tank 103 can be removed.
[0056] Overall storage: Organize and store the entire safety iron frame to prepare for the next use.
[0057] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
