A structure-stable respirator connector mounting structure

Abstract

This invention discloses a connector mounting structure for a structurally stable respirator, comprising a ring body, a mask inlet, a pressure ring, a sealing ring, a locking block, and a separate transmission mechanism. The mask inlet abuts against the sealing ring via the pressure ring. Multiple locking blocks pass through the gaps between multiple pressure blocks. Rotating the mask inlet causes the locking blocks to rotate to the underside of the pressure blocks, then a telescopic power ring pushes them upwards and abuts against the lower ends of multiple drive columns. Through friction transmission, the telescopic power ring rotates to control the rotation of multiple drive columns, which in turn controls the downward movement of a movable ring. This movable ring, via multiple connecting rods, drives multiple pressure blocks downwards, causing the pressure blocks to press against the upper side of the locking blocks. The downward pressure of the locking blocks ensures the pressure ring tightly presses against the sealing ring, guaranteeing a seal. Disassembly is performed by reversing the above steps, making disassembly and installation convenient.

Description

Technical Field

[0001] This invention belongs to the field of diving equipment accessories, and in particular relates to a connector mounting structure for a structurally stable breathing apparatus. Background Technology

[0002] Diving breathing apparatus is mainly used to provide breathing air for divers during diving. It uses compressed air and works by filling the cylinder with high-pressure air through an inflation tube connector. The high-pressure air then passes through a pressure reducer and a breathing valve before entering the mouth for the wearer to breathe. In current technology, the breathing mask and breathing valve are often connected by a connector. When the connector is connected to the breathing mask, it is usually done by threaded connection or snap-fit ​​connection. However, since the breathing mask moves with the diver, the existing connection method will make the connection structure between the breathing mask and the connector unstable and unreliable after long-term movement. At the same time, the installation and disassembly are also cumbersome. Therefore, it is necessary to upgrade the existing structure to improve structural stability and ease of installation and disassembly. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention solves the problem that the connection between the breathing mask and the connector is unstable and the disassembly and installation are inconvenient.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A connector mounting structure for a structurally stable respirator includes a ring body, a mask inlet, a pressure ring, a sealing ring, a locking block, and a separate transmission mechanism. The mask inlet is mounted on the upper end of the ring body. A pressure ring is provided around the lower end of the mask inlet. Multiple locking blocks are evenly installed around the pressure ring. The sealing ring is fixedly fitted around the upper end of the ring body. The separate transmission mechanism is mounted on the ring body. The separate transmission mechanism includes a pressure block, connecting rods, a movable ring, a drive column, and a telescopic power ring. A telescopic power ring is telescopically mounted on the lower end of the ring body. A movable ring is slidably fitted around the middle of the ring body. Multiple connecting rods are installed on the upper outer perimeter of the movable ring. Pressure blocks are installed on the inner side of the upper end of the device, and there are through gaps between the multiple pressure blocks; multiple drive columns are installed on the movable ring; the telescopic power ring abuts or separates from the lower ends of the multiple drive columns; the air inlet end of the mask abuts against the sealing ring sleeve through the pressure ring body, and multiple buckles pass through the through gaps of the multiple pressure blocks. Rotating the air inlet end of the mask causes the multiple buckles to rotate to the lower side of the multiple pressure blocks. The telescopic power ring pushes upward and abuts against the lower ends of the multiple drive columns. The rotation of the telescopic power ring controls the rotation of the multiple drive columns. The rotation of the multiple drive columns controls the downward movement of the movable ring, so that the movable ring drives the multiple pressure blocks to move downward through the multiple connecting rods, and the pressure blocks abut against the upper side of the buckles. After the telescopic power ring completes its rotation, it separates downward from the lower ends of the multiple drive columns.

[0005] Furthermore, a telescopic ring groove is formed on the outer perimeter of the middle four sides of the ring body; the movable ring is slidably mounted on the telescopic ring groove; multiple drive columns are axially and uniformly rotated and installed on the inner four sides of the telescopic ring groove; the drive columns are threadedly connected to the movable ring.

[0006] Furthermore, the split transmission mechanism also includes a transmission block; a drive ring groove is provided around the lower side of the ring body; the lower end of the drive column extends into the drive ring groove; the lower end of the drive column is connected to the transmission block; the telescopic power ring moves upward and its inner side is pressed against the outer side of multiple transmission blocks, and when the telescopic power ring rotates, it drives multiple transmission blocks to rotate synchronously.

[0007] Furthermore, the transmission block has a conical structure that is larger at the top and smaller at the bottom; the inner perimeter of the telescopic power ring has a conical annular structure that is smaller at the top and larger at the bottom.

[0008] Furthermore, the transmission block is a friction block, and the telescopic power ring is a friction ring; the transmission block and the telescopic power ring form a pressure friction transmission structure.

[0009] Furthermore, it also includes a telescopic mechanism; the telescopic mechanism includes a telescopic spring, a floating plate, and a lifting sleeve; floating slots are respectively opened on both sides of the lower end of the ring body; a telescopic spring is installed in the upper part of the floating slot, and a floating plate is slidably engaged in the lower part of the floating slot. The telescopic spring elastically presses the floating plate downwards, and the outer sides of the two floating plates are connected to a lifting sleeve, which is rotatably connected to the outer sides of the two floating plates; the upper end of the lifting sleeve is connected to a telescopic power ring.

[0010] Furthermore, the lifting sleeve is provided with a rotating snap-fit ​​groove on its inner periphery; the lifting sleeve is rotatably snapped onto the outer side of the two floating plates through the rotating snap-fit ​​groove on its inner periphery.

[0011] Furthermore, the outer ring surface of the sealing ring has a tapered structure that is smaller at the top and larger at the bottom; the sealing ring is made of corrosion-resistant rubber material.

[0012] Furthermore, the upper part of the ring body is provided with an annular insertion groove; the lower end of the air inlet of the mask is provided with an insertion ring; the insertion ring is inserted into the annular insertion groove.

[0013] The beneficial effects of this invention are as follows: 1. In this invention, the air inlet end of the mask abuts against the sealing ring sleeve via a pressure ring body. Multiple buckle blocks are inserted through the gaps between multiple pressure blocks. Then, the air inlet end of the mask is rotated, causing the multiple buckle blocks to rotate to the lower side of the multiple pressure blocks. Then, a telescopic power ring pushes upward and abuts against the lower end of multiple drive columns. Thus, through friction transmission, the telescopic power ring rotates to control the rotation of multiple drive columns. The rotation of multiple drive columns controls the downward movement of the movable ring, causing the movable ring to drive multiple pressure blocks to move downward through multiple connecting rods, and causing the pressure blocks to press against the upper side of the buckle blocks. In this way, the pressure blocks press the buckle blocks downward, so that the pressure ring body tightly presses against the sealing ring sleeve, ensuring sealing. Disassembly is performed by reversing the above operation, making disassembly and installation convenient.

[0014] 2. In this invention, a telescopic groove is formed on the outer perimeter of the central circumference of the main body of the ring. The movable ring slides and is mounted on the telescopic groove. Multiple drive posts are axially and evenly rotated around the inner circumference of the telescopic groove. All drive posts are threadedly connected to the movable ring. Thus, the longitudinal telescopic movement of the movable ring can only be controlled by the synchronous rotation of multiple drive posts. The telescopic power ring of this invention only pushes the telescopic power ring upward when it is necessary to drive multiple drive posts to rotate synchronously. In other cases, the telescopic power ring is separated downward from the transmission block at the lower end of the multiple drive posts. In this way, even if one or more drive posts are subjected to external force, they will not rotate because the multiple drive posts form an interlocking structure. This prevents the movable ring from accidentally telescopically moving, greatly improving the stability of the structure.

[0015] 3. To achieve a working mode where the telescopic power ring can be pushed upwards when multiple drive columns need to rotate synchronously, and separated downwards when synchronous rotation of multiple drive columns is not required, this invention designs a convenient telescopic mechanism. The telescopic mechanism includes a telescopic spring, a floating plate, and a lifting sleeve. Floating slots are respectively formed on both sides of the lower end of the ring body. The telescopic spring is installed at the upper part inside the floating slot, and the floating plate slides and engages at the lower part inside the floating slot. The telescopic spring elastically presses downwards against the floating plate, thus ensuring the floating plate stably receives downward pressure. The outer sides of the two floating plates are connected to a lifting sleeve, thus ensuring the lifting sleeve stably receives downward pressure. The pressure and lifting sleeve are rotatably connected to the outside of two floating plates. The upper end of the lifting sleeve is connected to a telescopic power ring. When it is necessary to synchronously drive the transmission blocks at the lower end of multiple drive columns, the telescopic power ring is pushed upward and presses against the multiple transmission blocks, while the telescopic spring is compressed. After the telescopic power ring has finished rotating, it is released. The downward pressing of the telescopic spring causes the floating plates to drive the lifting sleeve and the telescopic power ring to return to their original positions. This separates the telescopic power ring from the lower end of the multiple drive columns, thus achieving convenient automatic separation. The ingenious structural design prevents the multiple drive columns from rotating due to friction from the telescopic power ring. Attached Figure Description

[0025] The invention will now be described in further detail with reference to the accompanying drawings. Example 1

[0026] like Figures 1 to 8 As shown, a connector mounting structure for a structurally stable respirator includes a ring body 1, a mask inlet end 2, a pressure ring 3, a sealing ring 4, a locking block 5, and a separate transmission mechanism 6. The mask inlet end 2 is mounted on the upper end of the ring body 1. The lower end of the mask inlet end 2 is provided with a pressure ring 3 around its perimeter. Multiple locking blocks 5 are evenly installed around the pressure ring 3. The sealing ring 4 is fixedly sleeved around the upper perimeter of the ring body 1. The separate transmission mechanism 6 is mounted on the ring body 1. The separate transmission mechanism 6 includes a pressure block 61, a connecting rod 62, a movable ring 63, a drive column 64, and a telescopic power ring 65. A telescopic power ring 65 is telescopically installed at the lower end of the ring body 1. A movable ring 63 is slidably sleeved around the middle perimeter of the ring body 1. Multiple connecting rods 62 are installed on the upper end of the outer perimeter of the movable ring 63. Pressure blocks 61 are respectively installed on the inner side of the upper end of the connecting rods 62. Multiple pressure blocks 61 are provided with through gaps 611; multiple drive columns 64 are installed on the movable ring 63; the telescopic power ring 65 abuts or separates from the lower ends of the multiple drive columns 64; the mask air inlet 2 abuts against the sealing ring sleeve 4 through the pressure ring body 3; multiple buckle blocks 5 pass through the through gaps 611 of the multiple pressure blocks 61; rotating the mask air inlet 2 causes the multiple buckle blocks 5 to rotate to the lower side of the multiple pressure blocks 61; the telescopic power ring 65 pushes upward and abuts against the lower ends of the multiple drive columns 64; the rotation of the telescopic power ring 65 controls the rotation of the multiple drive columns 64; the rotation of the multiple drive columns 64 controls the movable ring 63 to move downward; the movable ring 63 drives the multiple pressure blocks 61 to move downward through the multiple connecting rods 62; and the pressure blocks 61 abut against the upper side of the buckle blocks 5; after the telescopic power ring 65 completes its rotation, it separates downward from the lower ends of the multiple drive columns 64. The outer ring of the sealing ring 4 has a tapered structure that is smaller at the top and larger at the bottom; the sealing ring 4 is made of corrosion-resistant rubber material. In this embodiment, the telescopic power ring 65 can slide up and down around the lower end of the ring body 1. When in use, the telescopic power ring 65 can be pushed upward.

[0027] In this embodiment, in order to facilitate the synchronous rotation of multiple drive columns 64 to drive the movable ring 63 to move up and down, a telescopic ring groove 11 is opened on the outer side of the middle perimeter of the ring body 1; the movable ring 63 is slidably installed on the telescopic ring groove 11; multiple drive columns 64 are axially and uniformly rotated and installed on the inner perimeter of the telescopic ring groove 11; the drive columns 64 are threadedly connected to the movable ring 63.

[0028] In this embodiment, in order for the telescopic power ring 65 to better control the synchronous rotation of multiple drive columns 64, the split transmission mechanism 6 also includes a transmission block 66; a drive ring groove 12 is provided around the lower side of the ring body 1; the lower end of the drive column 64 extends into the drive ring groove 12; the lower end of the drive column 64 is connected to the transmission block 66; the telescopic power ring 65 moves upward and its inner side is pressed against the outer side of multiple transmission blocks 66, and when the telescopic power ring 65 rotates, it drives multiple transmission blocks 66 to rotate synchronously.

[0029] In this embodiment, the transmission block 66 has a conical structure that is larger at the top and smaller at the bottom; the inner periphery of the telescopic power ring 65 has a conical annular structure that is smaller at the top and larger at the bottom. The transmission block 66 is a friction block, and the telescopic power ring 65 is a friction ring; the transmission block 66 and the telescopic power ring 65 form a pressure friction transmission structure. Example 2

[0030] like Figures 1 to 8 As shown, this embodiment refers to Embodiment 1, but differs in that the telescopic power ring 65 in this embodiment can automatically separate downwards from the lower ends of multiple drive columns 64 by external force, improving structural stability. It also includes a telescopic mechanism 7; the telescopic mechanism 7 includes a telescopic spring 71, a floating plate 72, and a lifting sleeve 73; floating slots 13 are respectively opened on both sides of the lower end of the ring body 1; the telescopic spring 71 is installed at the upper part inside the floating slot 13, and the floating plate 72 is slidably engaged at the lower part inside the floating slot 13; the telescopic spring 71 elastically presses downwards against the floating plate 72; the outer sides of the two floating plates 72 are connected to a lifting sleeve 73, which is rotatably connected to the outer sides of the two floating plates 72; the upper end of the lifting sleeve 73 is connected to the telescopic power ring 65. A rotating engaging groove 731 is provided around the inner periphery of the lifting sleeve 73; the lifting sleeve 73 is rotatably engaged with the outer sides of the two floating plates 72 through the rotating engaging groove 731 around its inner periphery. Example 3

[0031] like Figures 1 to 8 As shown, this embodiment refers to embodiment 2, the difference being that the docking stability of the ring body 1 and the mask air inlet 2 is improved. The upper end of the ring body 1 is provided with an annular insertion groove 14 around its perimeter; the lower end of the mask air inlet 2 is provided with an insertion ring 8; the insertion ring 8 is inserted into the annular insertion groove 14 for installation.

[0032] In this invention, the air inlet end 2 of the mask abuts against the sealing ring sleeve 4 via the pressure ring body 3. Multiple buckle blocks 5 are inserted through the through gaps 611 of multiple pressure blocks 61. Then, the air inlet end 2 of the mask is rotated, causing the multiple buckle blocks 5 to rotate to the lower side of the multiple pressure blocks 61. Then, the telescopic power ring 65 pushes upward and abuts against the lower end of multiple drive columns 64. Thus, through friction transmission, the telescopic power ring 65 rotates to control the rotation of multiple drive columns 64. The rotation of multiple drive columns 64 controls the downward movement of the movable ring 63, so that the movable ring 63 drives multiple pressure blocks 61 to move downward through multiple connecting rods 62, and the pressure blocks 61 abut against the upper side of the buckle blocks 5. In this way, the pressure blocks 61 press down on the buckle blocks 5, so that the pressure ring body 3 tightly abuts against the sealing ring sleeve 4, ensuring sealing. Disassembly can be performed by reversing the above operation, making disassembly and installation convenient.

[0033] In this invention, a telescopic annular groove 11 is formed on the outer periphery of the middle of the main body 1 of the annular ring. The movable ring 63 is slidably mounted on the telescopic annular groove 11. Multiple drive columns 64 are axially and evenly rotated around the inner periphery of the telescopic annular groove 11. All drive columns 64 are threadedly connected to the movable ring 63. Thus, the longitudinal telescopic movement of the movable ring 63 can only be controlled by the synchronous rotation of multiple drive columns 64. The telescopic power ring 65 of this invention is only pushed upward when it is necessary to drive multiple drive columns 64 to rotate synchronously. In other cases, the telescopic power ring 65 is separated downward from the transmission block 66 at the lower end of multiple drive columns 64. In this way, when one or more drive columns 64 are subjected to external force, they will not rotate because multiple drive columns 64 form an interlocking structure. This prevents the movable ring 63 from moving unexpectedly, greatly improving the stability of the structure.

[0034] To achieve the following working mode: when multiple drive columns 64 need to be driven to rotate synchronously, the telescopic power ring 65 can be pushed upwards; when multiple drive columns 64 do not need to be driven to rotate synchronously, the telescopic power ring 65 can be separated downwards, the present invention designs a convenient telescopic mechanism. The telescopic mechanism includes a telescopic spring 71, a floating plate 72, and a lifting sleeve 73. Floating slots 13 are respectively opened on both sides of the lower end of the ring body 1. The telescopic spring 71 is installed in the upper part of the floating slot 13, and the floating plate 72 is slidably engaged in the lower part of the floating slot 13. The telescopic spring 71 elastically presses the floating plate 72 downwards, so that the floating plate 72 stably obtains downward pressure. The outer sides of the two floating plates 72 are connected to a lifting sleeve 73, so that the lifting sleeve 73 stably obtains downward pressure. The lifting sleeve 73 is rotatably connected to the outside of the two floating plates 72. The upper end of the lifting sleeve 73 is connected to the telescopic power ring 65. When it is necessary to synchronously drive the transmission blocks 66 at the lower end of multiple drive columns 64, the telescopic power ring 65 is pushed upward and presses against the multiple transmission blocks 66, while the telescopic spring 71 is compressed. After the telescopic power ring 65 has finished rotating, it is released. The downward pressing of the telescopic spring 71 causes the floating plate 72 to drive the lifting sleeve 73 and the telescopic power ring 65 to return to their original position. This separates the telescopic power ring 65 from the lower end of the multiple drive columns 64, thus achieving convenient automatic separation. The ingenious structural design prevents the multiple drive columns 64 from rotating due to friction from the telescopic power ring 65.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
