Description

Technical Field

[0001] This utility model relates to the field of tools, specifically to a tracheal lock. Background Technology

[0002] In the maintenance of various industrial equipment, especially in pneumatic systems, the repair and replacement of air hoses often involves the secure locking of the hoses. Due to the varying sizes of air hoses—6mm, 8mm, 20mm, etc.—different equipment may use hoses of different specifications. Most air hose locks in related technologies employ simple mechanical structures for locking, and these locks often only accommodate one size of air hose connector. Furthermore, for air hose connectors with different outer diameters, the locks in these technologies cannot provide a flexible and quick adaptation method.

[0003] During the maintenance of industrial equipment, workers often need to lock the trachea to prevent accidental gas leaks or detachment, thus avoiding accidents. However, current technologies lock the trachea by bending and folding it, which affects its lifespan, reduces its durability, and increases wear and tear. Furthermore, existing methods of locking the trachea allow personnel to remove it at any time, failing to effectively isolate the gas source and resulting in poor safety.

[0004] In summary, the airway locks in the relevant technologies have problems such as poor adaptability and poor safety, and cannot effectively meet the needs of industrial equipment maintenance. Utility Model Content

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] This embodiment provides a tracheal lock. Figure 1 This is a schematic diagram of a tracheal lock according to an embodiment of the present utility model, as shown below. Figure 1 As shown, the tracheal lock includes: a first lock assembly 1, which includes a blind plate structure for sealing the insertion end of the tracheal connector; a second lock assembly 2, which has N opening slots 21 for accommodating connectors of trachea with different diameters; and a connector 3 for connecting the first lock assembly 1 and the second lock assembly 2. The N opening slots satisfy the following conditions: di < Li; di ≠ dj; di is the diameter of the i-th opening slot among the N opening slots, dj is the diameter of the j-th opening slot among the N opening slots, and Li is the length of the i-th opening slot among the N opening slots; i and j are natural numbers, 1 ≤ i ≤ N, 1 ≤ j ≤ N.

[0025] In this preferred embodiment, there is a first locking component 1 which includes a blind plate structure for closing the insertion end of the tracheal connector; a second locking component 2 which has N opening slots for accommodating connectors of tracheas with different diameters; and a connecting member 3 for connecting the first locking component 1 and the second locking component 2. By selecting different tracheal connectors according to the size of the trachea and including multiple opening slots in the tracheal lock, the adaptation of tracheas of multiple specifications is achieved. In the related art, the entire set of locks needs to be replaced every time the pipe diameter is changed. In the technical solution of this embodiment, the corresponding size of the opening slot can be selected for adaptation.

[0026] Specifically, di < Li. The inserted connector is not "suspended" or "loose", but is in a long and narrow opening slot (guide slot). This structure has the following technical effects: It has a self-guiding function when inserting the connector and is not easily skewed; after being inserted, due to more contact surfaces, the stability is improved and it is less likely to fall off; in addition, the diameter of each slot is different, di ≠ dj, with an independent aperture design to avoid misinsertion and improve safety. The possibility of misinserting connectors with different diameters decreases because the plug cannot be inserted, with high adaptation accuracy and reduced interface damage or air leakage caused by "inserting by brute force".

[0027] In this embodiment, the tracheal lock forms a kind of "physical coding" in its structure, making it easy for the operator to know which interface corresponds to which pipe. The first locking component 1 is a blind plate structure and the whole device can be closed. Combined with the detachable connecting member 3, when a certain interface is not in use, it can be directly sealed with the blind plate; if a certain slot is damaged, the second locking component 2 can be replaced instead of the whole lock; it is especially suitable for scenarios that require quick switching, cleaning, or maintenance.

[0028] As a preferred embodiment, the tracheal lock further includes: an outer surface of the first locking component 1 is provided with markings, and the markings include at least one of the following: tracheal caliber, installation direction, identification code, quick response code (QR code).

[0029] Through this embodiment, the tracheal caliber can be marked, explicitly prompting the interface adaptation specifications. It can avoid misinsertion: If the user has a trachea with a diameter of 8 mm in hand and the interface marking indicates a diameter of 10 mm, it cannot be inserted. Secondly, the operation efficiency can be improved. There is no need to repeatedly compare, try to insert, and unplug. Just looking at the markings can find the appropriate interface. In addition, it is also convenient for maintenance and troubleshooting. When the operation and maintenance personnel check for leaks, looking at the caliber parameters can tell whether the pipe is the appropriate trachea.

[0030] The installation direction markings ensure correct assembly. This addresses the issue of unclear orientation of structural components during assembly, especially when the first lock assembly 1 has a symmetrical structure or multiple installation methods exist. It reduces the possibility of reverse or incorrect installation, particularly in unfamiliar operating environments (nighttime, confined spaces, multiple shifts).

[0031] Regarding identification codes, unique tracking at the device level is possible. For example, this code can be a numerical identifier (such as A1, A2, etc.). Through identification codes, full lifecycle management of the device can be supported: which component was installed and when, how long it has been in service, and whether there are replacement records can all be indexed using the identification code; this facilitates quality traceability. If a batch of locks experiences a leakage problem, the problematic batch can be quickly located using the code. Furthermore, it allows for digital management through software systems. In smart manufacturing or hospital gas systems, each connector requires information registration, and coding is the foundation of this information system.

[0032] Regarding QR codes, they constitute a digital information integration entry point, transforming the tracheal lock from a "mechanical structure" into an "information node".

[0033] In implementation, the following methods can be adopted, such as: one item, one code, supporting information traceability and instant query by scanning the code: a simple scan with a mobile phone can display the parameters of the lock's compatible air hose, installation instructions, maintenance manual, historical records, etc. It can also assist in intelligent operation and maintenance and inspection. Maintenance personnel can scan the code to directly view interface status, service life, maintenance cycle, etc., during factory inspections. Secondly, it supports integration with IoT systems.

[0034] Preferably, the tracheal lock further includes: the first lock assembly 1 and the second lock assembly 2 are provided with corresponding modular interface mounting holes, which are used to connect external devices.

[0035] In this embodiment, both the first and second locking components have pre-drilled "interface holes" for installation. These holes are standardized and modular. The modular interface mounting holes are used to connect detachable and replaceable connection modules, which can be connected to different external devices, such as gas monitoring instruments, pressure regulators, additional control devices, safety valves / check valves, and other control components. The modular interface mounting holes allow it to connect not only to gas pipes but also to standardized interfaces, improving expandability.

[0036] Specifically, different modules can be plugged in according to actual needs, such as a sensor module for detecting air pressure or a filter module for filtering impurities. Secondly, when the equipment is damaged, the module is replaced instead of the whole machine, which greatly reduces maintenance costs. Thirdly, design redundancy can be reduced: it is not necessary to pre-embed all functions in the main structure of the lock; only mounting holes need to be reserved.

[0037] Preferably, the first lock assembly is provided with a first padlock hole 11, and the second lock assembly is provided with a second padlock hole 23; wherein, when the first lock assembly and the second lock assembly are closed, the first padlock hole and the second padlock hole coincide for padlocking.

[0038] In practice, the diameters of the N opening slots can include 9 mm, 11 mm, 12 mm, 13 mm, or 15 mm. Using different diameters for the N opening slots allows for the adaptation of various air tubes, achieving a safe locking mechanism on air tube connectors of different specifications. For example, air tube diameters include 9 mm, 11 mm, 12 mm, 13 mm, and 15 mm.

[0039] Preferably, the connector 3 includes a rivet and a rivet rod, respectively disposed on the first lock assembly 1 and the second lock assembly 2; the connector 3 also includes a slot and a snap-fit, respectively disposed on the first lock assembly 1 and the second lock assembly 2. This technical feature provides multiple methods for connecting the first lock assembly 1 and the second lock assembly 2, increasing the versatility of the connection. The riveting method simplifies installation, while the snap-fit ​​method facilitates disassembly during maintenance or replacement.

[0040] Preferably, both the first lock assembly 1 and the second lock assembly 2 are channel-shaped parts, which are formed by stamping stainless steel plates (see Appendix). Figure 2 This preferred embodiment ensures that the lock's manufacturing materials possess high strength, strong corrosion resistance, and good durability, thereby improving the product's service life. Preferably, the stainless steel contains chromium and nickel, with a chromium content of 18% and a nickel content of 8%. This allows the air hose lock to resist corrosion in many environments.

[0041] Preferably, the diameter of the mounting hole corresponding to the rivet is 4 mm, and the diameter of the padlock hole is 7 mm. This preferred embodiment allows for the safe installation and use of the padlock in the air hose lock.

[0042] This embodiment and its preferred embodiments provide a combined tracheal lock that can adapt to various sizes of tracheal connectors. This lock, through a simple and effective structural design, achieves secure locking on tracheal connectors of different sizes. Specifically, this embodiment, through a two-component design and the setting of multiple elongated slots (opening slots), achieves adaptation to various tracheal connectors, not only improving the convenience of operation but also effectively preventing human disassembly or misoperation, thus improving safety and reliability.

[0043] In practice, the material of the tracheal lock affects its performance. In this embodiment, the tracheal lock can be made of 1mm thick 304 stainless steel plate. Using 304 stainless steel plate to make the tracheal lock has advantages such as strong corrosion resistance, high strength, and good durability.

[0044] It should be noted that the stainless steel material of the tracheal lock in this embodiment may include 18% chromium and 8% nickel. In practice, the tracheal lock can resist corrosion in many environments.

[0045] In addition, regarding the strength and hardness of the tracheal lock, tracheal locks made of 304 stainless steel have high tensile strength and hardness, which can prevent the tracheal lock from deforming or breaking.

[0046] Secondly, regarding processing performance. The stainless steel used in the airway lock has different metal ratios, which has good cold and hot working performance, and is easy to form through processes such as cutting, stamping, and bending.

[0047] As a preferred embodiment, the tracheal lock can be manufactured using the method described in this embodiment.

[0048] In this embodiment, 304 stainless steel sheet is used as the material for manufacturing the airway lock. The process may include the following steps:

[0049] Step 1: Use 1mm thick 304 stainless steel sheet to press and form two channel-shaped parts, which can be assembled together (as shown below). Figure 2 );

[0050] Step 2: Select different tracheal connectors according to the size of the trachea (e.g., tracheal connector sizes: 6mm, 8mm, 10mm, 12mm, 14mm, 16mm);

[0051] Step 3: Measure the outer diameter of the endotracheal connector for the following sizes: 9mm, 11mm, 12mm, 13mm, and 15mm.

[0052] Step 4, according to the outer diameter of the air pipe connector, install the second locking assembly 2 (as follows). Figure 1 , 2 And 3) Long openings with different sized apertures (as shown below) Figure 1 and 3 );

[0053] Step 5: Drill a 4mm diameter hole for the rivet mounting hole and a 7mm diameter hole for the padlock, according to actual needs.

[0054] Preferably, in this embodiment, the first lock assembly 1 can be in the form of a blind plate to prevent the insertion of an external air tube.

[0055] In practice, in order to achieve better cooperation between the first lock assembly 1 and the second lock assembly 2, the first lock assembly 1 and the second lock assembly 2 are drilled with 4mm diameter holes as mounting holes for the rivets; 7mm diameter holes are used for padlocks; and 4mm diameter holes are drilled at the rivet points to assemble the two individual lock components into a whole using rivets.

[0056] In actual use, after the tracheal lock is assembled, it can be tested to check whether its locking function is working properly.

[0057] It should be noted that in practice, manufacturing tracheal locks requires multiple manufacturing processes. To better illustrate the structure of tracheal locks, the manufacturing processes will be explained in detail below.

[0058] (1) Size determination: Determine the external dimensions of the air pipe lock according to the structure and specific requirements of the lock, including the diameter, thickness, and size of the lock clamp groove.

[0059] (2) Structural design: Design the external structure of the tracheal lock, such as the shape of the lock slot, the position and shape of the lock tongue, etc., to ensure that the tracheal lock can securely lock the tracheal connector.

[0060] (3) Cutting: Using high-precision cutting technologies such as laser cutting or water jet cutting, the 304 stainless steel plate is cut into the blank shape of the air pipe lock according to the design dimensions. These cutting methods can ensure the flatness and precision of the cut edges.

[0061] (4) Stamping: The blank is stamped into a preliminary shape using a stamping die, including forming key structural parts such as the locking groove and locking tongue. During the stamping process, it is necessary to ensure the accuracy of the die and control the stamping pressure to prevent the stainless steel plate from cracking or deforming.

[0062] (5) Grinding and polishing: Grinding and polishing the surface of the air lock to remove burrs, scratches and other defects generated during the processing and improve the surface smoothness.

[0063] (6) Passivation treatment: To further improve the corrosion resistance of stainless steel, the valve lock can be passivated. Passivation treatment can form a dense oxide film on the surface of the valve lock, enhancing its corrosion resistance and increasing its service life.

[0064] (7) Dimensional Inspection: High-precision measuring tools are used to inspect the dimensions of the valve lock to ensure that it meets the design requirements. This includes measuring key dimensions such as diameter, thickness, and lock slot dimensions.

[0065] (8) Hardness test: The hardness of the valve lock is tested by a hardness tester to ensure that its hardness is within a reasonable range, so as to ensure strength without being too brittle and causing breakage.

[0066] (9) Assembly: Assemble the various components according to the design drawings, using screws, rivets, and other connectors to secure them. During assembly, ensure that the positions and connections of each component are correct and that the lock functions properly.

[0067] (10) Testing and Adjustment: After assembly, test the lock to check if its locking function is normal and if it can securely lock the air tube. If there are any problems, make the corresponding adjustments and improvements. This step ensures that the quality and performance of the lock meet the requirements.

[0068] This embodiment and its preferred embodiments provide a tracheal lock. The key to solving this problem lies in designing a lock that can adapt to various tracheal connector sizes, possesses high strength and corrosion resistance, thereby improving the safety and stability of the equipment. In particular, a tracheal lock with an adjustable aperture design is needed, which can accurately select the appropriate aperture for locking based on the outer diameter of different tracheal connectors, thus ensuring compatibility with different specifications of tracheal connectors and avoiding safety hazards such as detachment or loosening during use. Simultaneously, it is also necessary to ensure that the lock's manufacturing materials possess high strength, strong corrosion resistance, and good durability to extend the product's service life.

[0069] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
