Description

Technical Field

[0001] This utility model belongs to the field of chemical instrument technology, specifically relating to a high-temperature heating box. Background Technology

[0002] In fields such as chemical experiments, materials analysis, and biological detection, heating chambers are core equipment for achieving constant-temperature heating, drying, and reaction incubation of samples, and are widely used for the heating of glassware such as beakers, flasks, and test tubes. These glasswares, as common carriers in chemical experiments, have advantages such as transparency for easy observation and good chemical stability; however, their materials are brittle and have weak impact resistance, and their safety during use and placement directly affect the experimental process and the safety of operators.

[0003] Currently, the core heating support structure of existing chemical laboratory heating chambers is mostly a fixed or adjustable flat shelf, typically made of metal, ceramic, or fiberglass. The working principle involves placing the glassware to be heated directly on the shelf surface, and heating is achieved through hot air or thermal radiation generated by heating elements inside the chamber. However, this type of structure has significant technical drawbacks in practical applications, as follows:

[0004] The existing heating chamber shelves do not have a limiting mechanism for glass instruments. When multiple glass instruments are placed on the same shelf by hand at the same time, they are prone to colliding with each other and tipping over, whether they are being taken out of the heating chamber or not. Utility Model Content

[0005] In view of this, the present invention provides a high-temperature heating box to solve the problem that in the prior art, the shelves of the heating box are not equipped with limiting mechanisms for glass instruments. When multiple glass instruments are placed on the same shelf by hand at the same time, whether the glass instruments are taken out or taken out of the heating box, the instruments are prone to collide with each other, causing them to tip over.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A high-temperature heating box includes a box body with a heating chamber. The heating chamber has a placement plate, which is connected by several connecting posts to form a grid. The placement plate has a placement cylinder, and the side wall of the placement cylinder has several openings. The bottom of the placement cylinder has a buckle that mates with the connecting posts. The bottom of the buckle has a notch through which the connecting posts can be inserted. The diameter of the buckle is smaller than the diameter of the connecting posts, and the buckle is made of an elastic material.

[0008] With this technical solution, when glass instruments need to be heated, first insert the placement plate into the appropriate support structure in the heating chamber, then hold the placement tube fitted with the glass instrument, align the notch at the bottom of the buckle with any connecting post on the placement plate, and gently press the placement tube down. Because the diameter of the buckle is smaller than that of the connecting post and it is made of elastic material, the connecting post will squeeze the inner wall of the buckle, causing the buckle to expand elastically along the notch until the connecting post slides completely into the center of the buckle. At this time, the buckle relies on elastic reset to generate a continuous centripetal clamping force, firmly fixing the placement tube to the connecting post. During heating, the hot air flows through the grid gaps of the placement plate and then penetrates to the surface of the instrument through the opening on the side wall of the placement tube, achieving uniform heating.

[0009] Preferably, the width of the notch gradually decreases along the direction closer to the inside of the buckle.

[0010] With this technical solution, when installing the placement cylinder, first align the outer wide opening of the buckle notch with the connecting post. Since the outer width is greater than the diameter of the connecting post, it can be quickly inserted without precise alignment. Continue pressing down on the placement cylinder, and the connecting post moves along the notch towards the inner narrow opening. During this process, the inner wall of the notch gradually squeezes the connecting post, forcing the buckle to expand more elastically. When the connecting post reaches the inner narrow opening of the notch, the width of the narrow opening is less than the diameter of the connecting post. At this time, the inner wall of the buckle fits tightly with the connecting post, forming a "locking" effect and restricting the lateral movement of the connecting post within the buckle.

[0011] Preferably, the bottom of the placement tube is provided with a slot, and the two sides of the slot are respectively provided with fixing grooves; the top of the buckle is provided with a plug that can be inserted into the slot, and the two sides of the plug are respectively provided with mounting grooves. The mounting groove is provided with a fixing plate that cooperates with the fixing groove. One end of the fixing plate is connected to the mounting groove by a spring, and the other end extends out of the mounting groove.

[0012] When using this technical solution, when it is necessary to assemble the buckle and the placement cylinder, first align the insert block at the top of the buckle with the slot at the bottom of the placement cylinder, and then press the fixing block into the installation groove. During the insertion process, when the fixing plate aligns with the fixing grooves on both sides of the slot, the spring force pushes the fixing plate to reset, causing the fixing plate to pop out of the installation groove and lock into the fixing groove, forming a mechanical lock and ensuring that the buckle and the placement cylinder will not separate.

[0013] Preferably, the height of the insert is greater than the depth of the slot, the bottom of the mounting slot is provided with a sliding groove, one end of the sliding groove passes through the insert, the bottom of the insert is provided with a slider, the slider is slidably embedded in the sliding groove, one end of the slider extends out of the sliding groove and is connected to a pressing block, and the distance from the top of the pressing block to the top of the insert is greater than the depth of the slot.

[0014] With this technical solution, when assembling the buckle and the placement cylinder, because the height of the insert block is greater than the depth of the slot, the pressing block is always exposed on the outside of the bottom of the placement cylinder after the insert block is inserted into the slot, and will not be blocked by the slot. When it is necessary to disassemble the buckle, pinch the pressing blocks on both sides with your thumb and forefinger, press the pressing blocks inward to drive the slider to slide along the slide groove towards the installation slot. The slider pushes the fixing plate to compress the spring, so that the fixing plate is completely retracted into the installation slot. At this time, keep pressing and pull the buckle upward to complete the disassembly. After releasing the pressing block, the spring pushes the fixing plate to reset, and the slider and pressing block also return to the initial position with the fixing plate, which is convenient for the next assembly.

[0015] Preferably, a plurality of support blocks are provided on both sides of the inner wall of the heating chamber, and the plurality of support blocks are spaced apart along the height direction of the box, with a gap between two adjacent support blocks for inserting a plate.

[0016] Preferably, the bottom of the heating chamber is provided with a water tank.

[0017] Preferably, a hinged door is attached to one side of the heating chamber.

[0018] Preferably, the bottom of the housing is provided with support feet.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, by setting an elastic buckle and notch structure, on the one hand, the installation of the placement tube can be completed without the need for screws, clips and other tools, and a single person can quickly fix a placement tube, greatly improving the efficiency of disassembly and assembly; on the other hand, the number of placement tubes can be flexibly increased or decreased according to experimental needs, and the placement tubes can be used to place glass instruments, completely avoiding collisions and tipping caused by direct placement of instruments.

[0021] 2. In this utility model, by setting a linkage structure between the slider and the pressing block, the buckle can be disassembled manually without the need for tools such as tweezers or screwdrivers, which is especially suitable for scenarios where buckles need to be replaced temporarily during experiments.

[0037] Example

[0038] like Figures 1-7As shown in the figure, a high-temperature heating box is disclosed in this embodiment of the utility model, including a box body 100. The box body 100 has a heating chamber 103. The heating chamber 103 is provided with a placement plate 105. The placement plate 105 is connected by a plurality of connecting posts 107 to form a grid. The placement plate 105 is provided with a placement cylinder 200. The side wall of the placement cylinder 200 is provided with a plurality of openings 201. The bottom of the placement cylinder 200 is provided with a buckle 300 that cooperates with the connecting posts 107. The bottom of the buckle 300 is provided with a notch 302 through which the connecting posts 107 can be inserted. The diameter of the buckle 300 is smaller than the diameter of the connecting posts 107. The buckle 300 is made of an elastic material. It should be noted that the enclosure 100 provides a closed support frame for the equipment, isolating it from external interference; the heating chamber 103 is the core area for high-temperature heating, ensuring stable temperature; the grid-shaped placement plate 105 supports the placement cylinder 200 and the instrument through the connecting column 107, while reserving a hot airflow channel; the placement cylinder 200 is used to place glass instruments and restrict their displacement; the elastic buckle 300 achieves quick fixing / separation of the placement cylinder 200 and the placement plate 105 through deformation. Working principle: When heating glass instruments, first insert the placement plate 105 into the appropriate support structure inside the heating chamber 103, then hold the placement tube 200 with the glass instrument in place, align the notch 302 at the bottom of the buckle 300 with any of the connecting posts 107 on the placement plate 105, and gently press the placement tube 200 down. Because the diameter of the buckle 300 is smaller than that of the connecting post 107 and it is made of elastic material, the connecting post 107 will squeeze the inner wall of the buckle 300, causing the buckle 300 to expand elastically along the notch 302 until the connecting post 107 slides completely into the center of the buckle 300. At this time, the buckle 300 relies on elastic reset to generate a continuous centripetal clamping force, firmly fixing the placement tube 200 to the connecting post 107. During heating, the hot air flows through the grid gaps of the placement plate 105, and then penetrates to the surface of the instrument through the opening 201 on the side wall of the placement tube 200, achieving uniform heating. In this solution, by setting up the elastic buckle 300 and the notch 302 structure, on the one hand, the installation of the placement tube 200 can be completed without the need for screws, clips and other tools, and a single person can quickly fix a placement tube 200, greatly improving the efficiency of disassembly and assembly; on the other hand, the number of placement tubes 200 can be flexibly increased or decreased according to experimental needs, and the placement tube 200 can place glass instruments, completely avoiding collisions and tipping caused by direct placement of instruments.

[0039] like Figure 7As shown, in another embodiment, the width of the notch 302 gradually decreases along the direction closer to the inside of the buckle 300. It should be noted that when installing the placement cylinder 200, first align the outer wide opening of the notch 302 of the buckle 300 with the connecting post 107. Since the outer width is greater than the diameter of the connecting post 107, it can be quickly inserted without precise alignment. Continue to press down on the placement cylinder 200, and the connecting post 107 moves along the notch 302 towards the inner narrow opening. During this process, the inner wall of the notch 302 gradually squeezes the connecting post 107, forcing the buckle 300 to expand more elastically. When the connecting post 107 reaches the inner narrow opening of the notch 302, the width of the narrow opening is less than the diameter of the connecting post 107. At this time, the inner wall of the buckle 300 and the connecting post 107 fit tightly together, forming a "locking" effect, which restricts the lateral swaying of the connecting post 107 within the buckle 300.

[0040] like Figure 6 and Figure 7 As shown, in another embodiment, the bottom of the placement cylinder 200 is provided with a slot 202, and fixing grooves 203 are respectively provided on both sides of the slot 202; the top of the buckle 300 is provided with a plug that can be inserted into the slot 202, and mounting grooves 303 are respectively provided on both sides of the plug. A fixing plate 306 that cooperates with the fixing groove 203 is provided in the mounting groove 303. One end of the fixing plate 306 is connected to the mounting groove 303 through a spring 304, and the other end extends outside the mounting groove 303. It should be noted that the slot 202 and the plug are the positioning structures of the buckle 300 and the placement cylinder 200, ensuring that the connection between the two is accurate; the fixing groove 203, the fixing plate 306, and the spring 304 form an elastic locking mechanism to realize the detachable fixing of the buckle 300. Working principle: When it is necessary to assemble the buckle 300 and the placement cylinder 200, first align the insert block at the top of the buckle 300 with the slot 202 at the bottom of the placement cylinder 200, and then press the fixing block into the mounting groove 303. During the insertion process, when the fixing plate 306 is aligned with the fixing grooves 203 on both sides of the slot 202, the spring 304 pushes the fixing plate 306 to reset, so that the fixing plate 306 pops out of the mounting groove 303 and is locked into the fixing groove 203, forming a mechanical lock and ensuring that the buckle 300 and the placement cylinder 200 will not separate.

[0041] like Figure 6 and Figure 7As shown, in another embodiment, the height of the insert block is greater than the depth of the slot 202. The bottom of the mounting groove 303 is provided with a sliding groove 305, one end of which passes through the insert block. The bottom of the insert block is provided with a slider 307, which is slidably embedded within the sliding groove 305. One end of the slider 307 extends outside the sliding groove 305 and connects to a pressing block 308. The distance from the top of the pressing block 308 to the top of the insert block is greater than the depth of the slot 202. It should be noted that the sliding groove 305 provides a sliding track for the slider 307. The slider 307 and the pressing block 308 form a linkage operation structure to achieve rapid retraction of the fixing plate 306. The height design of the insert block and the pressing block 308 prevents the pressing block 308 from being obstructed by the slot 202. Working principle: When assembling the buckle 300 and the placement cylinder 200, because the height of the insert block is greater than the depth of the slot 202, after the insert block is inserted into the slot 202, the pressing block 308 is always exposed on the outside of the bottom of the placement cylinder 200 and will not be blocked by the slot 202. When it is necessary to disassemble the buckle 300, pinch the pressing blocks 308 on both sides with your thumb and forefinger and press the pressing blocks 308 inward to drive the slider 307 to slide along the slide groove 305 towards the mounting groove 303. The slider 307 pushes the fixing plate 306 to compress the spring 304, so that the fixing plate 306 is completely retracted into the mounting groove 303. At this time, while maintaining the pressing state, pull the buckle 300 upward to complete the disassembly. After releasing the pressing block 308, the spring 304 pushes the fixing plate 306 to reset, and the slider 307 and the pressing block 308 also return to the initial position with the fixing plate 306, which is convenient for the next assembly. In this solution, by setting up a linkage structure between slider 307 and pressing block 308, the buckle 300 can be disassembled manually without the need for tools such as tweezers and screwdrivers. This is especially suitable for scenarios where buckle 300 needs to be replaced temporarily during experiments.

[0042] like Figure 2 As shown, in another embodiment, support blocks 104 are respectively provided on both sides of the inner wall of the heating chamber 103. There are multiple support blocks 104, which are spaced apart along the height direction of the housing 100, forming a gap between adjacent support blocks 104 for inserting a placement plate 105. It should be noted that the multiple layers of support blocks 104 constitute a height-adjustable bracket for the placement plate 105, adapting to glass instruments of different sizes through different height gaps, which is the core structure for improving the versatility of the equipment.

[0043] like Figure 2 As shown, in another embodiment, a water tank 106 is provided at the bottom of the heating chamber 103. It should be noted that the function of the water tank 106 is to collect liquids (such as instrument condensate, accidental leaks of liquid).

[0044] like Figure 1As shown, in another embodiment, a switch door 101 is hinged to one side of the heating chamber 103. It should be noted that the switch door 101 is used to open or close the heating chamber 103.

[0045] like Figure 1 As shown, in another embodiment, the bottom of the housing 100 is provided with support feet 102. It should be noted that the support feet 102 isolate the housing 100 from the influence of the ground environment, while enhancing the overall stability of the equipment.

[0046] The working principle of this utility model is as follows:

[0047] When using this high-temperature heating chamber to heat glass instruments, first, according to the height of the glass instrument to be heated, select the corresponding height gap of the support blocks 104 on both sides of the inner wall of the heating chamber 103, and horizontally insert the placement plate 105 into the gap. The height of the placement plate 105 can be flexibly adjusted through the spacing design of the multi-layer support blocks 104 to ensure that the instrument can fit the space of the heating chamber 103. Next, assemble the placement cylinder 200 and the buckle 300, align the insert at the top of the buckle 300 with the slot 202 at the bottom of the placement cylinder 200, press the fixing plate 306 to retract it into the mounting groove 303, and push the insert to fully insert into the slot 202. At this time, the fixing plate 306 pops out and locks into the slot 202 under the elastic force of the spring 304. The fixing grooves 203 on both sides of 02 form a mechanical lock, completing the stable connection between the two; then, holding the glass instrument placement tube 200 with the glass instrument on it, align the notch 302 at the bottom of the buckle 300 with any of the connecting posts 107 on the placement plate 105. Since the width of the notch 302 gradually decreases along the inner direction, the wide opening on the outer side makes it easy to quickly put the connecting post 107 in. Continue to press down on the placement tube 200, and the connecting post 107 moves inward along the notch 302 to the narrow opening, squeezing the buckle 300 so that it expands elastically along the notch 302 until the connecting post 107 slides completely into the center of the buckle 300. At this time, the buckle 300 elastically resets and generates a centripetal clamping force, which firmly fixes the placement tube 200 on the connecting post 107.

[0048] Close the hinged switch door 101 on one side of the heating chamber 103 to seal the heating chamber 103 and reduce heat loss. After heating is started, the hot air flow in the heating chamber 103 circulates through the gaps in the grid-like placement plate 105 and then penetrates through the opening 201 on the side wall of the placement cylinder 200 to the surface of the glass instrument to achieve uniform heating.

[0049] When it is necessary to disassemble the buckle 300, pinch the pressing block 308 at the bottom of the buckle 300 and press it inward. This will cause the slider 307 to slide along the slide groove 305, pushing the fixing plate 306 to compress the spring 304 and fully retract into the mounting groove 303. At this time, the fixing plate 306 will disengage from the fixing groove 203. Keep pressing and pull the buckle 300 upward to complete the disassembly. After releasing the pressing block 308, the spring 304 will push the fixing plate 306, slider 307 and pressing block 308 to reset for the next assembly.
