Description

Technical Field

[0001] This utility model belongs to the technical field of medical testing tools, specifically relating to a drilling tool for preventing tipping of aerosol bottles. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] In the process of drug quality control and research and development, it is necessary to perform content determination, related substance analysis, and microbiological testing on aerosol drugs. These drugs are usually packaged in small aluminum or steel pressure canisters with valves. When the drug inside the canister cannot be completely removed by normal spraying, or when it is necessary to directly obtain the drug inside the canister for homogeneity studies, destructive sampling of the pressure canister is necessary.

[0004] The prior art discloses a multifunctional aerosol punching and sampling device, including a base, a support shaft and a fixed seat on the support shaft. The fixed seat is provided with a feed column and a hand crank. One end of the hand crank is equipped with a gear, which meshes with a rack axially arranged on the feed column. The bottom end of the feed column is connected to a locking needle clamp, and a piercing needle is installed on the locking needle clamp. The base is provided with a locking clamp, and the locking clamp has a sample slot for placing the aerosol bottle.

[0005] The above method, which uses a hand crank to move the feed column, which in turn moves the piercing needle up and down to open the aerosol bottle in the sample chamber, has the following drawbacks:

[0006] The sample compartment of the above scheme gradually decreases in diameter from top to bottom, which can accommodate aerosol bottles of different diameters. However, this also results in a smaller storage height for larger aerosol bottles. When the piercing needle pierces the aerosol bottle with downward pressure, there is a risk that the bottom of the aerosol bottle is not sufficiently restrained, which may cause the aerosol bottle to shake or even tip over. Piercing the aerosol bottle and causing it to tip over may lead to leakage of the medicine and cause pollution. Furthermore, the above scheme uses a feed column to drive the piercing needle from top to bottom to pierce the aerosol bottle. This direct pressure piercing method may cause local dents in the aerosol bottle body or bending of the needle, making it impossible to effectively open the aerosol bottle body. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide an anti-tipping drilling tool for aerosol bottles, which can solve the technical problems of insufficient restraint on the bottom of the aerosol bottle in the prior art and the inability to effectively open the aerosol bottle due to direct pressure puncture.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A drilling tool for preventing tipping of aerosol bottles is provided, including a hollow base, a bracket fixedly connected to the base, and the center of the bracket being aligned with the center of the base;

[0010] A threaded drill rod is threaded vertically to the center of the bracket. The threaded drill rod is coaxial with the aerosol can. A drill bit for rotating and cutting the aerosol can is fixedly connected to the bottom end of the threaded drill rod, and a drill rod handle is fixedly connected to the top end of the threaded drill rod.

[0011] An aerosol canister for holding the aerosol bottle is fixedly connected to the center of the base, and the aerosol canister is equipped with a locking mechanism for locking the aerosol bottle.

[0012] The base is equipped with a height adjustment component to support and adjust the placement height of the aerosol bottle; the top surface of the aerosol bottle is flush with the top surface of the aerosol canister.

[0013] Preferably, the height adjustment assembly includes a plurality of separable, stackable height adjustment blocks.

[0014] Preferably, the height adjustment block is a metal plate structure.

[0015] Preferably, the bracket is a portal frame structure, with both ends of the bracket vertically fixed to the top surface of the base.

[0016] Preferably, the bracket is made of square tubing, with a guide hole in the center of the bracket, and a guide cylinder is fixedly connected inside the guide hole.

[0017] Preferably, a limit nut is fixedly connected to the top of the guide cylinder, and the threaded drill rod is threadedly engaged with the limit nut.

[0018] Preferably, the locking mechanism includes a locking bolt that penetrates the side wall of the aerosol bottle and a locking nut that is threaded onto the locking bolt, the locking nut being fixedly connected to the side wall of the aerosol bottle.

[0019] Preferably, a locking handle is fixedly connected to the end of the locking bolt away from the aerosol bottle.

[0020] Preferably, the diameter of the aerosol can barrel is larger than the diameter of the aerosol can.

[0021] Preferably, the bottom surface of the base is provided with an anti-slip pad.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are:

[0023] This invention uses a rotary cutting method to create a hole on the top surface of the aerosol bottle, avoiding the problems of localized dents or needle bending that can occur with traditional direct pressure puncture. The invention also utilizes a combination of the aerosol bottle barrel and a height adjustment component to ensure the top surface of the aerosol bottle is flush with the top surface of the barrel, completely enclosing the aerosol bottle within the barrel and preventing it from tipping over during drilling. Furthermore, a locking mechanism secures the aerosol bottle, preventing it from shaking during drilling and improving operational safety while reducing the risk of leakage.

[0030] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses an anti-tipping drilling tool for aerosol bottles, such as... Figure 1 , Figure 2 , Figure 3As shown, the device includes a hollow cuboid base 1, on which a support 2 is fixedly connected, with the center of the support 2 aligned with the center of the base 1; an aerosol can 7 for accommodating an aerosol bottle 6 is installed at the center of the base 1. In this embodiment, the base is formed by bending and welding a metal sheet, and the aerosol can 7 can be connected to the base by welding.

[0032] like Figures 1 to 3 As shown, a threaded drill rod 4 is threadedly connected to the center of the bracket 2 in the vertical direction. The threaded drill rod 4 is coaxially arranged with the aerosol bottle 7. A drill bit 5 for rotating and cutting the aerosol bottle 6 is fixedly connected to the bottom end of the threaded drill rod 4, and a drill rod handle 3 is fixedly connected to the top end of the threaded drill rod 4.

[0033] Understandably, rotating the drill rod handle 3 drives the threaded drill rod 4, and the threaded drill rod 4 feeds the drill bit 5 through rotation, so that the drill bit 5 is directly downward and in contact with the top surface of the aerosol bottle 6. Continuing to rotate the drill rod handle 3 makes the drill bit 5 open a hole on the top surface of the aerosol bottle 6.

[0034] In this embodiment, the aerosol bottle 7 is a hollow cylindrical tube with openings on both the top and bottom surfaces, and the aerosol bottle 7 is internally connected to the base 1. Figures 1 to 3 As shown, a locking mechanism for locking the aerosol bottle 6 is fixedly connected to the aerosol bottle 7, and the locking mechanism is perpendicular to the aerosol bottle 7. It can be understood that placing the aerosol bottle 6 inside the aerosol bottle 7 and locking it in place using the locking mechanism ensures that the bottle does not shake or rotate when the top surface of the aerosol bottle 6 is opened, thus guaranteeing the stability of the bottle.

[0035] In this embodiment, as Figure 1 As shown, a height adjustment component 8 is placed inside the base 1 to support and adjust the placement height of the aerosol bottle 6. In this embodiment, different types of aerosol bottles 6 have different heights. By placing the height adjustment component 8 inside the base 1 to support the aerosol bottle 6, the top surface of the aerosol bottle 6 can be kept at a consistent height when placed inside the aerosol canister 7.

[0036] It should be noted that, in this embodiment, the height adjustment component 8 needs to adjust the placement height of the aerosol bottle 6 so that the top surface of the aerosol bottle 6 is flush with the top surface of the aerosol canister 7. This design requirement is to ensure that when an opening is made on the top surface of the aerosol bottle 6, the aerosol bottle 6 will not tip over and cause contamination.

[0037] It should be noted that this embodiment uses a rotary cutting method to drill holes in the top surface of the aerosol bottle 6, avoiding the problems of localized dents or needle bending that may occur with traditional direct pressure puncture. This embodiment uses the aerosol bottle barrel 7 and a locking mechanism to stably support and fix the aerosol bottle 6, preventing it from shaking or tipping over during drilling and effectively avoiding the risk of drug leakage. This contrasts sharply with the shortcomings of existing technologies where the sample holder does not adequately constrain large-diameter aerosol bottles, leading to shaking or even tipping and causing drug leakage and contamination. This embodiment significantly improves operational safety and reduces the risk of drug leakage.

[0038] Furthermore, the overall structural design of this embodiment is simple, and the connection relationships between components are clear. For example, the fixed connection between the bracket and the base, and the threaded connection between the threaded drill rod and the bracket, all adopt mature and reliable mechanical connection methods. This reduces the technological requirements for drilling tool processing and can reduce manufacturing costs.

[0039] like Figure 1 As shown, the height adjustment assembly 8 includes multiple separable, stackable height adjustment blocks of uniform thickness. It can be understood that by increasing or decreasing the number of height adjustment blocks, the placement height of aerosol cans 6 of different lengths can be adjusted in a stepped manner. For example, if the aerosol can 6 is short, more height adjustment blocks can be stacked to raise it so that its top surface is flush with the top surface of the aerosol canister 7; if the aerosol can 6 is long, the number of height adjustment blocks can be reduced. This ensures that the drill bit 5 at the bottom of the threaded drill rod 4 can drill a hole in the top surface of the aerosol can 6 from the same height.

[0040] In this embodiment, the bottom surface of the base 1 is open. According to the height of the aerosol bottle 6, a corresponding number of height adjustment blocks are placed on the table and stacked. The aerosol bottle 6 is placed on the height adjustment blocks, and then the base 1 is placed on the table from top to bottom, so that the aerosol bottle 6 passes through the aerosol canister 7.

[0041] like Figure 1 As shown, the height adjustment block of the height adjustment component 8 is a metal plate structure. This metal plate structure has high strength and rigidity, providing stable support for the aerosol bottle 6 placed on it, and preventing deformation of the height adjustment block when the drill bit 5 cuts the aerosol bottle 6. This stable support ensures that the aerosol bottle 6 remains at the preset placement height, reducing the risk of drilling deviation or tool damage due to unstable positioning of the aerosol bottle 6, thereby improving operational safety and efficiency.

[0042] like Figure 1As shown, the bracket 2 has a portal frame structure, with both ends of the bracket 2 vertically fixed to the top surface of the base 1. In this embodiment, the portal frame structure means that the bracket has two vertical support columns and a horizontal beam connecting the two support columns, resembling a door frame. This structural design has good mechanical stability and load-bearing capacity, and can disperse the lateral forces and torques acting on the bracket during drilling, thereby enhancing overall stability.

[0043] In this embodiment, the support 2 is made of square tubing. Square tubing has high bending and torsional stiffness, providing more robust and stable support for the entire drilling tool. A guide hole is provided at the center of the support 2, such as... Figure 2 As shown, a guide cylinder 10 is fixedly connected inside the guide hole. The guide cylinder 10 serves as a guide element for the threaded drill rod 4, keeping the threaded drill rod 4 coaxial with the aerosol canister 7, and allowing the threaded drill rod to move vertically up and down along a predetermined path. This avoids problems such as inaccurate drilling or damage to the aerosol canister 6 caused by the deviation of the threaded drill rod 4.

[0044] like Figure 1 , Figure 2 As shown, a limiting nut 9 is fixedly connected to the top of the guide cylinder 10, and the threaded drill rod 4 is threadedly engaged with the limiting nut 9. When the threaded drill rod 4 is rotated by the drill rod handle 3, the external thread of the threaded drill rod 4 meshes with the internal thread of the limiting nut 9 fixed to the top of the guide cylinder 10, converting the rotational motion into precise linear motion.

[0045] Understandably, since the top surface of each aerosol can 6 is flush with the top surface of the aerosol canister 7 when placed, the limiting nut 9 serves as a fixed reference point for the vertical stroke of the threaded drill rod 4. When the drill rod handle 3 contacts the top of the limiting nut 9, the drill bit 5 enters the aerosol can 6 to the same set depth each time. This, in conjunction with the height adjustment component 8, prevents over-drilling or insufficient drilling depth.

[0046] like Figures 1 to 3 As shown, the locking mechanism includes a locking bolt 12 penetrating the side wall of the aerosol canister 7, and a locking nut 11 threaded onto the locking bolt 12. The locking nut 11 is fixedly connected to the side wall of the aerosol canister 7. It can be understood that the locking mechanism is a device used to securely fix the aerosol canister 6 inside the aerosol canister 7, preventing the aerosol canister 6 from shaking or rotating during drilling, thus ensuring drilling accuracy and operational safety.

[0047] In this embodiment, the locking bolt 12 penetrates the side wall of the aerosol canister 7 (a through hole can be pre-machined on the side wall of the aerosol canister 7) and directly contacts the aerosol bottle 6, applying radial pressure to secure the aerosol bottle 6 within the aerosol canister 7. This connection method allows adjustment of the depth of the locking bolt's insertion into the aerosol canister 7 by rotating the locking bolt 12, thus accommodating aerosol bottles 6 of different diameters and applying locking force. This radial force generated by the threaded fastening effectively prevents the aerosol bottle 6 from rotating or shaking during drill cutting, improving drilling stability and safety.

[0048] like Figures 1 to 3 As shown, a locking handle 13 is fixedly connected to the end of the locking bolt 12 away from the aerosol canister 7, which allows the user to apply rotational force to the locking bolt 12 through the locking handle 13, thereby improving the convenience and efficiency of operation.

[0049] In this embodiment, the diameter of the aerosol canister 7 is larger than the diameter of the aerosol bottle 6. This dimensional relationship is designed to ensure that the aerosol bottle 6 can be smoothly placed into or removed from the aerosol canister 7, reducing resistance during operation.

[0050] In this embodiment, the bottom surface of the base 1 is open, and anti-slip pads are fixedly connected (e.g., glued) to the bottom of the side walls of the base 1. It is understood that when the threaded drill rod 4 is rotated via the drill rod handle 3 and the drill bit 5 cuts the aerosol bottle 6, a reaction force or lateral force is generated. At this time, the anti-slip pads provide sufficient friction to resist these forces, effectively preventing unnecessary sliding or displacement of the base during operation. This ensures that the drill bit 5 can cut the aerosol bottle 6, avoiding drilling deviation or damage to the aerosol bottle due to tool movement. It also improves operational safety and reduces the risk of injury caused by accidental tool movement.

[0051] Specific working principle:

[0052] Place the base 1 on the table. The height from the top of the aerosol can 7 to the table is known. Calculate the height difference based on the height of the aerosol bottle 6. Then place the corresponding number of height adjustment blocks on the table and stack them. Place the aerosol bottle 6 on the height adjustment blocks.

[0053] Then, the base 1 is placed from top to bottom so that the aerosol bottle 6 passes through the aerosol canister 7, and the locking mechanism is used to lock the aerosol bottle 6 inside the aerosol canister 7.

[0054] Then, rotate the drill rod handle 3 to drive the threaded drill rod 4. The threaded drill rod 4 achieves the feed of the drill bit 5 through rotation, so that the drill bit 5 is directly downward and in contact with the top surface of the aerosol bottle 6. Continue to rotate the drill rod handle 3 to make the drill bit 5 open a hole on the top surface of the aerosol bottle 6.

[0055] Finally, rotate the drill rod handle 3 in the opposite direction to lift the drill bit 5, then rotate the locking handle 13 in the opposite direction to release the limit, lift the base 1 and remove the aerosol bottle 6.

[0056] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
