Description

Technical Field

[0001] This utility model relates to the technical field of portable gas cylinder valve disassembly clamps, specifically a portable gas cylinder valve disassembly clamp. Background Technology

[0002] Self-contained breathing apparatus (SCBA) is widely used in various fields such as fire fighting, chemical industry, shipbuilding, petroleum, metallurgy, warehousing, laboratories, and mining. It enables firefighters and rescue personnel to safely and effectively carry out firefighting, rescue, and medical assistance in complex environments such as those with dense smoke, toxic gases, vapors, or oxygen deficiency. When inspecting and testing the cylinders of SCBAs, the cylinders must first be secured and the valves removed.

[0003] Currently, most clamps used to secure gas cylinders for valve removal are integrally welded or cast structures. While these traditional clamps are simple in structure, they also have significant drawbacks: First, they are bulky and fixed in shape, taking up considerable space when stored in non-use mode or transported to different testing locations, causing inconvenience in transportation and warehousing. Second, due to their one-piece design, the clamping components are not replaceable, making them inflexible for gas cylinders of different diameters and specifications, resulting in poor versatility. When testing multiple types of gas cylinders, multiple sets of different clamps are often required, increasing equipment costs and the complexity of storage and management. Furthermore, the fixed structure makes modular design difficult, hindering functional expansion or rapid maintenance based on actual needs. Utility Model Content

[0004] The purpose of this utility model is to provide a portable gas cylinder valve disassembly clamp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable gas cylinder valve disassembly clamp, including a base, a movable seat slidably connected to the top of the base, a clamping block provided on the top of the movable seat, and a docking component and a stabilizing component provided on the outer surfaces of the movable seat and the clamping block; The docking components include: The docking groove is used to cooperate with the fixing column to achieve positioning. The insertion rod is used to engage with the insertion hole to achieve a limiting position. Limiting element, used to stabilize the insertion rod.

[0006] Preferably, the docking groove is formed on the top of the movable seat, and a fixing post is fixed to the bottom of the movable seat. An insertion hole is formed on the outer surface of the fixing post, and an insertion rod is provided on the outer surface of the movable seat. The insertion rod passes through the movable seat and is slidably connected to the movable seat. A pressure plate is fixed on the outer surface of the insertion rod, and a spring is fixed on the outer surface of the pressure plate. The end of the spring away from the pressure plate is fixed to the outer surface of the movable seat. A linkage groove is formed inside the movable seat, and the linkage groove communicates with the docking groove. When the fixing post is installed into the docking groove, pressing the pressure plate can drive the insertion rod to insert into the insertion hole, thereby realizing the mutual positioning of the fixing post and the insertion hole.

[0007] Preferably, the limiting member includes a connecting groove formed on the outer surface of the movable seat. A fixing block is fixed to the outer surface of the insertion rod. A sliding groove is formed on the inner side of the connecting groove. A locking block is slidably connected to the outer surface of the sliding groove. A second spring is fixed to the outer surface of the locking block. The end of the second spring away from the locking block is fixed to the inner wall of the sliding groove. A movable block is slidably connected to the outer surface of the insertion rod. A magnet is fixed to the outer surface of the insertion rod. The magnet is magnetically connected to the movable block. When the insertion rod is inserted, the inclined surface of the fixing block contacts and squeezes the locking block, forcing it to compress the second spring and retract. When the fixing block completely passes the locking block, the locking block quickly resets under the push of the second spring, and its planar side firmly abuts against the planar side of the fixing block, forming a mechanical interlock, thereby reliably locking the insertion rod. Unlocking process: When disassembly is required, press the pressure plate again to drive the movable block to move and force the locking block to retract again; when the movable block passes the locking block, release it, and the insertion rod will be pushed by the spring to reset as a whole. The locking block will then slide back to its initial position, the lock will be released, and the clamping block and the movable seat can be separated.

[0008] Preferably, the stabilizing component includes a through hole on the outer surface of the pressure plate. A rotating rod is rotatably connected to the outer surface of the movable base. A movable groove is formed on the outer surface of the rotating rod. A movable column is slidably connected to the inner wall of the movable groove. A spring is fixed to the outer surface of the movable column. The end of the spring away from the movable column is fixed to the inner wall of the movable groove. A baffle is fixed to the outer surface of the rotating rod. The stabilizing groove is formed on the outer surface of the movable base. The baffle is used to prevent accidental contact with the pressure plate. When carrying or replacing the clamping block, rotating the rotating rod can rotate the baffle to be parallel to the through hole, thereby making room for pressing.

[0009] Preferably, a screw is rotatably connected to the inner side of the base, and a threaded block is slidably connected to the inner wall of the base. The screw passes through the threaded block and is threadedly connected to the threaded block. A knob is rotatably connected to the outer surface of the base. The output shaft of the knob passes through the base and is fixed to the outer surface of the screw. The screw is provided with two opposite threads. Rotating the knob drives the screw to rotate, causing the threaded block, the moving seat, and the clamping block to move closer together synchronously, thus clamping the gas cylinder. Reversing the knob releases the clamp.

[0010] Preferably, the side of the fixed block and the movable block that is far from each other is set as an inclined surface, and the end of the locking block that is far from the second spring is set as an inclined surface. When the fixed block and the movable block are in contact with each other, it is easy to release the limiting position of the locking block. The inclined surface of the locking block is abutted, which allows the locking block to move into the slide groove without affecting the insertion of the rod.

[0011] Preferably, the end of the movable column away from the spring is set in an arc shape, so that when it rotates with the rotating rod, the movable column can come into contact with the inner wall of the stabilizing groove, thereby driving the movable column to move into the movable groove without affecting the normal rotation of the rotating rod.

[0012] Compared with the prior art, this utility model provides a portable gas cylinder valve disassembly clamp, which has the following advantages: 1. This portable gas cylinder valve disassembly clamp, through its docking assembly, achieves connection via the insertion and locking of a plug rod. During installation, pressing the pressure plate pushes the plug rod into place, causing the inclined surface of the fixing block to compress the locking block and retract it. After passing the locking block, the locking block returns to its original position under the action of spring two, its plane abutting against the plane of the fixing block, locking the plug rod. During disassembly, pressing the pressure plate again pushes the movable block to disengage the locking block; after releasing, spring one pushes the plug rod back to its original position, the locking block slides back to the surface of the fixing block, releasing the limit and allowing for separation for easy carrying and replacement.

[0013] 2. This portable gas cylinder valve disassembly clamp features a stabilizing component. Under normal conditions, the baffle is in contact with the pressure plate, preventing accidental activation. When operation is required, rotating the lever retracts the movable column; continuing to rotate until the movable column aligns with the stabilizing groove triggers a spring to push it in and lock the lever. At this point, the baffle rotates to be parallel to the through hole, creating space for pressing, allowing normal operation of the pressure plate. Attached Figure Description

Detailed Implementation

[0016] like Figures 1-6 As shown, this utility model provides a technical solution: a portable gas cylinder valve disassembly clamp, including a base 1, a movable seat 5 slidably connected to the top of the base 1, a clamping block 6 provided on the top of the movable seat 5, and a docking component 7 and a stabilizing component 8 provided on the outer surfaces of the movable seat 5 and the clamping block 6; the docking component 7 includes: a docking groove 70, a fixing post 71, an insertion hole 72, an insertion rod 74, a pressure plate 75, a first spring 76, a linkage groove 78, a limiting member 77, a connecting groove 770, a fixing block 771, a sliding groove 772, a locking block 773, a second spring 774, a movable block 775, and a magnet 776.

[0017] A docking groove 70 is formed at the top of the movable base 5. A fixing post 71 is fixed at the bottom of the movable base 5. An insertion hole 72 is formed on the outer surface of the fixing post 71. An insertion rod 74 is provided on the outer surface of the movable base 5, passing through the movable base 5 and slidably connected to the movable base 5. A pressure plate 75 is fixed on the outer surface of the insertion rod 74. A spring 76 is fixed on the outer surface of the pressure plate 75. The end of the spring 76 away from the pressure plate 75 is fixed to the outer surface of the movable base 5. A linkage groove 78 is formed inside the movable base 5, communicating with the docking groove 70. A limiting member 77 is provided, including a connecting groove 770, which is formed on the outer surface of the movable base 5. A fixing block 771 is fixed on the outer surface of the insertion rod 74. A sliding groove 772 is provided on the inner side of 770. A locking block 773 is slidably connected to the outer surface of the sliding groove 772. A second spring 774 is fixed to the outer surface of the locking block 773. The end of the second spring 774 away from the locking block 773 is fixed to the inner wall of the sliding groove 772. A movable block 775 is slidably connected to the outer surface of the insertion rod 74. A magnet 776 is fixed to the outer surface of the insertion rod 74. The magnet 776 is magnetically connected to the movable block 775. The side of the fixed block 771 away from the movable block 775 is set as an inclined surface. The end of the locking block 773 away from the second spring 774 is set as an inclined surface. After the fixed post 71 is installed into the docking groove 70, pressing the pressure plate 75 can drive the insertion rod 74 to insert into the insertion hole 72, realizing the mutual limiting of the fixed post 71 and the insertion hole 72. During this process, the inclined surface of the fixing block 771 contacts the inclined surface of the locking block 773, pushing the locking block 773 back into the slide groove 772 and compressing the second spring 774; when the fixing block 771 passes the locking block 773, the second spring 774 is released, pushing the locking block 773 back to its original position, so that its flat side abuts against the flat side of the fixing block 771, thereby locking the insertion rod 74 and ensuring the stable connection between the fixing post 71 and the docking groove 70. When disassembly is required, press the pressure plate 75 again to move the movable block 775 toward the locking block 773; when the movable block 775 passes the locking block 773, release the pressure plate 75, the first spring 76 is released, and pushes the insertion rod 74 back to its original position. At this point, the locking block 773 moves with the movable block 775 until it is in contact with the fixed block 771. Then, the locking block 773 slides from the surface of the movable block 775 back to the outer surface of the fixed block 771, releasing the restriction on the insertion rod 74 and allowing it to completely exit the insertion hole 72. This separates the clamping block 6 from the movable seat 5, facilitating disassembly or replacement. The magnet 776 attracts the movable block 775 back to its original position, preparing it for the next use.

[0018] The stabilizing component 8 includes a through hole 80, which is formed on the outer surface of the pressure plate 75. A rotating rod 81 is rotatably connected to the outer surface of the movable seat 5. A movable groove 83 is formed on the outer surface of the rotating rod 81. A movable column 84 is slidably connected to the inner wall of the movable groove 83. A spring 85 is fixed on the outer surface of the movable column 84. The end of the spring 85 away from the movable column 84 is fixed to the inner wall of the movable groove 83. A baffle 82 is fixed on the outer surface of the rotating rod 81. A stabilizing groove 86 is formed on the outer surface of the movable seat 5. The end of the movable column 84 away from the spring 85 is set to be arc-shaped. The outer surface of the baffle 82 contacts the pressure plate 75, which can effectively prevent accidental contact with the pressure plate 75 and ensure operational stability. When it is necessary to carry or replace the clamp 6, rotate the rotating rod 81. The outer surface of the movable column 84 abuts against the inner wall of the stabilizing groove 86, pushing the movable column 84 into the movable groove 83 and compressing the spring 85. When the movable column 84 is aligned with the stabilizing groove 86, the spring 85 is released, pushing the movable column 84 back into the stabilizing groove 86 to lock the rotating rod 81 and prevent it from rotating. At this time, the baffle 82 is parallel to the through hole 80 and no longer obstructs the pressure plate 75, allowing normal pressing operations to be performed.

[0019] A screw 2 is rotatably connected to the inner side of the base 1, and a threaded block 3 is slidably connected to the inner wall of the base 1. The screw 2 passes through the threaded block 3 and is threadedly connected to the threaded block 3. A knob 4 is rotatably connected to the outer surface of the base 1. The output shaft of the knob 4 passes through the base 1 and is fixed to the outer surface of the screw 2. The screw 2 is provided with two opposite threads. Rotating the knob 4 drives the screw 2 to rotate, causing the threaded block 3, the moving seat 5, and the clamping block 6 to move closer together, thus completing the clamping of the gas cylinder.

[0020] When installation is required, the fixing post 71 is installed into the mating groove 70. Pressing the pressure plate 75 then moves the insertion rod 74 into the insertion hole 72, thus limiting the mutual positioning of the fixing post 71 and the insertion hole 72. Simultaneously, when the pressure plate 75 is pressed, the inclined surface of the fixing block 771 abuts against the inclined surface of the locking block 773, causing the locking block 773 to move into the sliding groove 772, compressing the spring 774. When the fixing block 771 passes the locking block 773, the spring 774 is released, causing the locking block 773 to reset. The side of the locking block 773 away from the inclined plane abuts against the side of the fixing block 771 away from the inclined plane, thus limiting the insertion rod 74 and preventing it from affecting the stability of the fixing post 71 and the docking groove 70. At the same time, the outer surface of the baffle 82 abuts against the surface of the pressure plate 75, thus preventing accidental pressing of the pressure plate 75 and affecting stability. At this time, it can be used normally. Turning the knob 4 will drive the screw 2 to rotate. At this time, the threaded block 3, the moving seat 5, and the clamping block 6 will come closer to each other, thus clamping the gas cylinder. When it is necessary to move or replace the clamping block 6, Rotate the rotating rod 81. At this time, the outer surface of the movable column 84 abuts against the inner wall of the stabilizing groove 86, which can drive the movable column 84 to move into the movable groove 83. At this time, the spring 85 is compressed. When the position of the movable column 84 is parallel to the stabilizing groove 86, the spring 85 is released, which can drive the movable column 84 to return to the stabilizing groove 86, thus preventing the rotating rod 81 from rotating on its own. At this time, the baffle 82 is parallel to the through hole 80, and the pressure plate 75 can be pressed normally, so that the movable block 775 moves closer to the locking block 773. When the movable block 775 passes through... When the locking block 773 is engaged, the pressure plate 75 is released, and the spring 76 is released, allowing the insertion rod 74 to return to its original position. At this time, the locking block 773 moves the movable block 775 closer to the fixed block 771 until they are in contact. Then, the locking block 773 moves from the surface of the movable block 775 to the outer surface of the fixed block 771, which releases the limit and allows the insertion rod 74 to completely disengage from the insertion hole 72. At this time, the clamping block 6 and the movable seat 5 can be separated normally, which is convenient for disassembly, separation, carrying or replacement. At the same time, the magnet 776 attracts the movable block 775 to return to its original position, which is convenient for subsequent use.

[0021] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
