Description

Technical Field

[0001] This invention relates to the field of gas holder technology, and specifically to a fully automatic special gas holder. Background Technology

[0002] An automatic special gas cabinet is an intelligent, closed-loop supply and distribution system specifically designed for flammable, explosive, highly toxic, highly corrosive, and high-purity specialty gases (such as silane SiH4, chlorine Cl2, nitrogen trifluoride NF3, and phosphine PH3). Its core purpose is to provide continuous, stable, high-purity, and safely controllable gas delivery to downstream process equipment (such as etching machines, deposition equipment, and ion implanters). In precision industries such as semiconductor manufacturing, the purity and flow stability of gases directly determine chip yield. Therefore, the special gas cabinet is not only a mechanical structure but also the first line of defense for ensuring process repeatability and inherent factory safety. Through microenvironmental control, it safely delivers highly hazardous specialty gases from the gas source (cylinder) to the user end, achieving fully automated purging, switching, leak monitoring, and emergency response during this process.

[0003] For example, utility model patent CN223826079U provides a special gas supply cabinet, which includes a cabinet body and a positioning device. The positioning device includes a fixing mechanism, a restraining strap, and a positioning groove. The fixing mechanism is vertically installed inside the cabinet, and the restraining strap forms a restraining area with it. The positioning groove is located on the base, vertically aligned with the restraining area, and its diameter is larger than the cylinder diameter. The gas cylinder is placed between the restraining area and the positioning groove. Although this structure can fix gas cylinders of different sizes, the restraining strap fixing method still has obvious shortcomings. The length of the restraining strap is fixed and cannot be automatically adjusted according to changes in the cylinder diameter. When changing to different specifications of gas cylinders, it is easy for it to be too loose or too tight, resulting in insufficient radial restraint force and difficulty in reliable fixing. This may not only cause the gas cylinder to shake or shift, but also easily cause damage or leakage to the pipeline joints, posing a safety hazard. Summary of the Invention

[0004] This invention provides a fully automatic special gas holder to solve the problems of unreliable gas cylinder fixing, easy shaking and displacement, and potential safety hazards in existing gas holders.

[0005] The present invention provides a fully automatic special gas cabinet with the following technical solution: A fully automatic special gas cabinet for placing gas cylinders includes a cabinet body and at least one mounting mechanism. The mounting mechanism includes at least one binding assembly. The binding assembly includes a lifting frame, binding straps, a tensioning unit, a one-way locking unit, and an unlocking unit.

[0006] The lifting frame is installed on the inner wall of the cabinet, and its position is adjustable. The lifting frame and gas cylinder are distributed sequentially along a first direction, with the gas cylinder located on the side of the lifting frame away from the inner wall of the cabinet it is attached to. At least one sliding groove assembly is provided on the side of the lifting frame closest to the gas cylinder. The sliding groove assembly includes a mounting groove and a locking groove, which are located on both sides of the gas cylinder along a second direction. Both the first and second directions are horizontal and perpendicular to each other.

[0007] The tensioning unit includes a accumulator, a torque cylinder, and a spring. The accumulator is housed in a mounting slot with its axis vertically aligned. The torque cylinder is coaxial with the accumulator and is fitted around the outside of the accumulator, allowing the torque cylinder to rotate relative to it. The spring connects the torque cylinder and the accumulator. One end of a strap is fixed and wound around the torque cylinder. The other end of the strap is fixed with a locking block that engages with a locking slot. The strap secures the gas cylinder to the lifting frame.

[0008] The one-way locking unit is used to prevent the strap from retracting into the mounting groove under the action of the spring as it is pulled outward from the mounting groove. The unlocking unit is used to release the one-way locking unit's restriction on the strap after the locking block is embedded in the locking groove, and the strap tends to retract into the mounting groove under the driving force of the spring.

[0009] Furthermore, the lifting frame includes a connecting frame and at least one limiting block, the connecting frame being slidably mounted on the inner wall of the cabinet. The limiting block is U-shaped, with its opening facing the gas cylinder. The limiting block includes a crossbar, a first stop bar, and a second stop bar. The crossbar is fixedly mounted on the side of the connecting frame closest to the gas cylinder. One end of the first stop bar and one end of the second stop bar are both fixedly connected to the side of the crossbar furthest from the connecting frame. The first stop bar and the second stop bar are inclined, gradually moving away from the crossbar. A mounting slot is located on the first stop bar and is positioned along its extension direction. A locking slot is located on the second stop bar and is vertically positioned. The gas cylinder is located within the U-shaped opening area enclosed by the crossbar, the first stop bar, and the second stop bar.

[0010] Furthermore, the one-way locking unit is located on the side of the torque cylinder away from the connecting frame. The one-way locking unit includes a locking element and two one-way shafts. The one-way shafts are vertically arranged and rotatably mounted in the mounting groove. The two one-way shafts are distributed along a third direction, which is horizontal and perpendicular to the extension direction of the first stop lever. The third direction is not perpendicular to either the first or second direction. A strap is threaded between the two one-way shafts, and the one-way shafts and the straps are in frictional contact.

[0011] When the strap is pulled outward from the mounting slot, it drives the one-way shaft to rotate in the forward direction. When the strap retracts into the mounting slot, it drives the one-way shaft to rotate in the reverse direction. The locking element is used to restrict the reverse rotation of the one-way shaft when the locking block is not embedded in the slot.

[0012] Furthermore, the locking element includes a fixing block, two pawls, and two first springs. The fixing block is disposed on the upper side of the limiting block and is located between the two one-way shafts. Two first sliding grooves are formed on the fixing block, sequentially distributed along a third direction. Each pawl is disposed within one first sliding groove and is capable of sliding along the third direction. Each pawl engages with a ratchet tooth to limit the ratchet tooth's reverse rotation. Each first spring is disposed within one first sliding groove, and the first spring connects the inner wall of the first sliding groove to the pawl.

[0013] Furthermore, the unlocking unit includes a first slider and a second spring. The first slider is slidably disposed on the upper side of the first stop lever. An adjustment groove is formed on the first slider, and the fixing block is located in the adjustment groove. The second spring is disposed in the adjustment groove and connects the inner wall of the adjustment groove and the first slider.

[0014] Two first inclined grooves are formed within the adjusting groove, and the two first inclined grooves are distributed sequentially along a third direction. The first inclined grooves are set at an inclination. A sliding rod is fixedly installed at the upper end of each pawl, and the sliding rod is set vertically. Each sliding rod is slidably set in one of the first inclined grooves. When the first slider moves away from the connecting frame, the two pawls move closer to each other along a third direction with the cooperation of the sliding rod and the first inclined groove.

[0015] Furthermore, a second sliding groove is provided on the limiting block, which communicates with the locking slot. The second sliding groove and the locking slot are distributed sequentially in a direction gradually moving away from the connecting frame. The unlocking unit also includes a second slider, a third spring, and a steel cable. The second slider is slidably disposed within the second sliding groove and the locking slot along the extension direction of the second stop bar.

[0016] The second slider has a first inclined surface. The first inclined surface is used to contact the locking block. During the process of the locking block being inserted into the locking slot, the locking block presses against the first inclined surface, driving the second slider to move towards the connecting frame. The two ends of the steel rope are connected to the first slider and the second slider, respectively.

[0017] Furthermore, the cabinet also includes at least one rotating mechanism, which comprises a rotating disk and a limiting component. The rotating disk is rotatably mounted on the bottom wall inside the cabinet, and the gas cylinder is placed on the rotating disk. The limiting component is used to restrict the rotation of the rotating disk after the locking block is embedded in the locking slot.

[0018] Furthermore, the limiting assembly includes a movable frame, a lead screw, a motor, and at least one friction block. The movable frame is slidably disposed within the cabinet along a first direction. The movable frame and the rotating disk are sequentially distributed along the first direction. The friction block is disposed on the movable frame and is used to abut against the rotating disk to limit the rotation of the rotating disk.

[0019] The lead screw is positioned along the first direction and is rotatably mounted within the cabinet, revolving around its own axis. The lead screw and the movable frame are connected via a transmission mechanism. When the lead screw rotates forward, it drives the movable frame to move closer to the rotating disk. The motor is fixedly mounted within the cabinet, and one end of the lead screw is connected to the motor's output shaft.

[0020] Furthermore, a sensor is installed on the second slider to sense the contact state between the first inclined plane and the locking block. A controller is installed on the motor to control the motor to drive the lead screw to rotate forward when the sensor detects contact between the first inclined plane and the locking block. The controller also controls the motor to drive the lead screw to rotate in the reverse direction when the sensor detects that the first inclined plane and the locking block have disengaged.

[0021] Furthermore, the installation mechanism also includes an adjustment assembly, which comprises a rack, a gear, and a splined rod. The splined rod is vertically positioned and rotatably mounted within the cabinet. The accumulator is slidably fitted onto the splined rod, and the accumulator and the splined rod rotate synchronously.

[0022] The gear is fixedly mounted on the splined rod, and the gear and splined rod are coaxially arranged. The rack is fixedly mounted on the movable frame, and the rack is arranged along the first direction, with the gear and rack meshing. When the movable frame moves towards the rotating disk, the rack drives the splined rod to rotate in the forward direction through the gear, so that the accumulator rotates relative to the torque cylinder, and the spring stores power.

[0023] The beneficial effects of this invention are as follows: This fully automatic special gas holder utilizes an adjustable-length strap with an internal spring. This allows the strap to flexibly adjust its extension length according to the diameter of different gas cylinders, and under the recoil force of the spring, it tightly adheres to the outer wall of the gas cylinder, effectively solving the problems of fixed length and poor adaptability of traditional straps. Simultaneously, this design utilizes the preset torque provided by the spring to ensure sufficient and reliable radial clamping force when holding gas cylinders of different sizes, preventing the gas cylinders from shaking or shifting during use, and significantly improving the safety and stability of the gas cylinder fixation.

[0024] This invention employs a segmented pulling and step-by-step positioning operation. After the strap is pulled out, a one-way locking unit maintains its current length, completing the fixing operation without continuous pulling. The locking block automatically retracts and tightens after engaging the slot, effectively avoiding the effort required for continuous pulling and the risk of the strap slipping and rebounding, injuring personnel or damaging internal components. During disassembly, simply pull out the locking block; the one-way locking unit automatically maintains the strap's current pulled-out length, preventing rapid retraction and collisions. Furthermore, there's no need to readjust the pull-out length for subsequent uses, significantly simplifying the bottle-changing process.

[0025] This invention eliminates safety hazards such as displacement, tipping, and pipeline leakage caused by unreliable fixing of gas cylinders through a reliable fixing and safe operation mechanism. It effectively protects the personal safety of operators and the integrity of precision components inside the cabinet, and comprehensively improves the inherent safety level of fully automatic special gas cabinets in high-safety-level application scenarios such as semiconductors.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1 to 13 As shown in the figure, an embodiment of the present invention provides a fully automatic special gas cabinet for placing gas cylinders 200, including a cabinet body 100 and at least one mounting mechanism. The mounting mechanism includes at least one binding assembly. The binding assembly includes a lifting frame, binding straps 620, a tensioning unit, a one-way locking unit, and an unlocking unit.

[0031] The lifting frame is installed on the inner wall of the cabinet 100, and its position is adjustable. The cabinet 100 has multiple first positioning holes 140, which are distributed sequentially along the vertical direction. The lifting frame has a second positioning hole 615. After aligning the second positioning hole 615 with a corresponding first positioning hole 140, a connecting pin is inserted into the first positioning hole 140 and the second positioning hole 615 to complete the positioning of the lifting frame.

[0032] The lifting frame and gas cylinder 200 are distributed sequentially along the first direction, with the gas cylinder 200 located on the side of the lifting frame away from the inner wall of the cabinet 100 it is attached to. At least one sliding groove assembly is provided on the side of the lifting frame closest to the gas cylinder 200. The sliding groove assembly includes a mounting groove 611 and a locking groove 612. The mounting groove 611 and the locking groove 612 are located on opposite sides of the gas cylinder 200 along the second direction, where both the first and second directions are horizontal and perpendicular to each other.

[0033] The tensioning unit includes a accumulator 660, a torque cylinder 650, and a spring 670. The accumulator 660 is housed within a mounting slot 611, with its axis vertically aligned. The torque cylinder 650 is coaxial with the accumulator 660 and is sleeved around the outside of the accumulator 660, allowing the torque cylinder 650 to rotate relative to the accumulator 660. The spring 670 connects the torque cylinder 650 and the accumulator 660. One end of a strap 620 is fixed and wound around the torque cylinder 650. The other end of the strap 620 is fixedly fitted with a locking block 621, which engages with a locking slot 612. The strap 620 secures the gas cylinder 200 to the lifting frame.

[0034] The one-way locking unit is used to prevent the strap 620 from retracting into the mounting groove 611 under the action of the spring 670 during the process of the strap 620 being pulled outwards from the mounting groove 611. The unlocking unit is used to release the one-way locking unit from limiting the strap 620 after the locking block 621 is embedded in the locking groove 612, and the strap 620 tends to retract into the mounting groove 611 under the driving force of the spring 670.

[0035] In other embodiments, there are multiple mounting mechanisms, which are sequentially distributed along the second direction. Each mounting mechanism includes multiple binding components, which are sequentially distributed along the vertical direction.

[0036] After placing the gas cylinder 200 inside the cabinet 100, pull the locking block 621 at the end of the strap 620 to extend the strap 620 outward from the mounting slot 611 to an appropriate length. During the extension of the strap 620, the torque cylinder 650 rotates relative to the accumulator cylinder 660, causing the built-in spring 670 to complete energy storage. The one-way locking unit prevents the strap 620 from retracting into the mounting slot 611 under the action of the spring 670 during the extension process, thus preventing the strap 620 from automatically retracting due to the rebound force of the spring 670.

[0037] Once the strap 620 is pulled out to the appropriate length to secure the gas cylinder 200, the locking block 621 is inserted into the slot 612. At this point, the one-way locking unit releases the restriction on the strap 620, and under the action of the spring 670, the excess strap 620 automatically retracts into the mounting slot 611, so that the strap 620 fits tightly against the outer wall of the gas cylinder 200 and is taut, thus completing the binding and securing of the gas cylinder 200.

[0038] Firstly, the adjustable-length strap 620 can accommodate gas cylinders 200 of different sizes. This device relies on the preset torque within the torque cylinder 650 to ensure that the strap 620 provides sufficient and reliable clamping force when holding gas cylinders 200 of different sizes, flexibly adapting to the fixing needs of various specifications of gas cylinders 200. The torque of the spring 670 is set such that when binding the smallest gas cylinder 200, the retraction torque of the spring 670 can still drive the strap 620 to adhere tightly to the outer wall of the gas cylinder 200, forming a stable and reliable clamping and fixing effect. At the same time, the maximum torque of the spring 670 is less than the maximum force applied by the operator when manually pulling the strap 620, avoiding excessive torque from the spring 670 making the strap 620 difficult to pull out manually.

[0039] Meanwhile, the design adopts a segmented pulling and step-by-step positioning operation method, which makes the fixing process of the strap 620 labor-saving and safe, effectively avoiding the effort caused by continuous pulling and the risk of the strap 620 rebounding after being released.

[0040] When it is necessary to disassemble the gas cylinder 200, simply pull the locking block 621 out of the locking slot 612. At this time, the one-way locking unit again restricts the strap 620 from retracting into the mounting slot 611 under the action of the spring 670, keeping the strap 620 at its current extended length without the need for repeated adjustments. It also prevents the strap 620 from retracting rapidly after the locking block 621 is pulled out, avoiding collision damage to the operator and internal components of the cabinet 100.

[0041] In this embodiment, the lifting frame includes a connecting frame 610 and at least one limiting block 680. The connecting frame 610 is slidably disposed on the inner wall of the cabinet 100. The limiting block 680 is U-shaped, with its opening facing the gas cylinder 200. The limiting block 680 includes a crossbar, a first stop bar, and a second stop bar. The crossbar is fixedly disposed on the side of the connecting frame 610 near the gas cylinder 200. One end of the first stop bar and one end of the second stop bar are both fixedly connected to the side of the crossbar away from the connecting frame 610. The first stop bar and the second stop bar are inclined and gradually move away from the crossbar. The mounting groove 611 is located on the first stop bar and is disposed along the extension direction of the first stop bar. The slot 612 is located on the second stop bar and is vertically disposed. The gas cylinder 200 is located within the U-shaped opening area enclosed by the crossbar, the first stop bar, and the second stop bar.

[0042] In this embodiment, the one-way locking unit is located on the side of the torque cylinder 650 away from the connecting frame 610. The one-way locking unit includes a locking member and two one-way shafts 630. The one-way shafts 630 are vertically arranged and rotatably disposed within the mounting groove 611. The two one-way shafts 630 are distributed along a third direction, which is horizontal and perpendicular to the extension direction of the first stop lever. The third direction is not perpendicular to either the first or second direction. A strap 620 passes between the two one-way shafts 630, and the one-way shafts 630 and the strap 620 are in frictional contact.

[0043] When the strap 620 is pulled outward from the mounting groove 611, the strap 620 can drive the one-way shaft 630 to rotate in the forward direction. When the strap 620 is retracted into the mounting groove 611, the strap 620 can drive the one-way shaft 630 to rotate in the reverse direction. The locking member is used to restrict the reverse rotation of the one-way shaft 630 when the locking block 621 is not embedded in the locking groove 612.

[0044] In this embodiment, the locking element includes a fixing block 614, two pawls 647, and two first springs 648. The fixing block 614 is fixedly disposed on the upper side of the limiting block 680 and is located between the two one-way shafts 630. The fixing block 614 has two first sliding grooves sequentially distributed along a third direction. Each pawl 647 is disposed in one of the first sliding grooves and can slide along the third direction. Each pawl 647 is used to engage with a corresponding ratchet tooth 631 to restrict the ratchet tooth 631 from rotating in the opposite direction. Each first spring 648 is disposed in one of the first sliding grooves, and the first spring 648 connects the inner wall of the first sliding groove to the side of the pawl 647 away from the ratchet tooth 631.

[0045] In this embodiment, the unlocking unit includes a first slider 644 and a second spring 645. The first slider 644 is slidably disposed on the upper side of the first stop lever along the extending direction of the first stop lever. An adjustment groove is provided on the first slider 644, and the fixing block 614 is located in the adjustment groove. The second spring 645 is disposed in the adjustment groove and connects the inner wall of the adjustment groove and the first slider 644.

[0046] Two first inclined grooves 646 are formed within the adjusting groove, and the two first inclined grooves 646 are distributed sequentially along the third direction. The first inclined grooves 646 are inclined and gradually move away from each other as they approach the connecting frame 610. A sliding rod 649 is fixedly provided at the upper end of each pawl 647. The sliding rod 649 is vertically arranged and slidably disposed within one of the first inclined grooves 646. When the first slider 644 moves away from the connecting frame 610, the two pawls 647 move closer to each other along the third direction with the cooperation of the sliding rod 649 and the first inclined groove 646, causing the pawls 647 and the ratchet 631 to disengage.

[0047] In this embodiment, the limiting block 680 has a second sliding groove 613, which communicates with the locking slot 612. The second sliding groove 613 and the locking slot 612 are distributed sequentially along a direction gradually moving away from the connecting frame 610. The unlocking unit also includes a second slider 642, a third spring 643, and a steel rope 641. The second slider 642 is slidably disposed within the second sliding groove 613 and the locking slot 612 along the extension direction of the second stop bar.

[0048] The second slider 642 has a first inclined surface that gradually moves away from the connecting frame 610 from top to bottom. The first inclined surface is used to contact the locking block 621. During the process of the locking block 621 being inserted into the locking slot 612, the locking block 621 presses against the first inclined surface, driving the second slider 642 to move closer to the connecting frame 610. The two ends of the steel rope 641 are respectively connected to the first slider 644 and the second slider 642. When the second slider 642 moves closer to the connecting frame 610, the steel rope 641 is released, and the second spring 645 drives the first slider 644 to move away from the connecting frame 610.

[0049] In this embodiment, at least one rotating mechanism is also provided inside the cabinet 100. The rotating mechanism includes a rotating disk 300 and a limiting component. The rotating disk 300 is rotatably mounted on the bottom wall inside the cabinet 100, and the gas cylinder 200 is placed on the rotating disk 300. The limiting component is used to restrict the rotation of the rotating disk 300 after the locking block 621 is embedded in the locking slot 612. A pipeline 110 is provided inside the cabinet 100. The pipeline 110 has an interface, and the gas cylinder 200 has an air outlet for connecting to the interface.

[0050] In this embodiment, the limiting assembly includes a movable frame 400, a lead screw 130, a motor, and at least one friction block 420. The movable frame 400 is slidably disposed within the cabinet 100 along a first direction. The movable frame 400 and the rotating disk 300 are sequentially distributed along the first direction. The friction block 420 is fixedly disposed on the movable frame 400 and is used to abut against the rotating disk 300 to limit the rotation of the rotating disk 300.

[0051] The lead screw 130 is positioned along a first direction and is rotatably mounted within the cabinet 100 around its own axis. The lead screw 130 and the movable frame 400 are in a transmission engagement. When the lead screw 130 rotates forward, it drives the movable frame 400 to move closer to the rotating disk 300; when the lead screw 130 rotates in the reverse direction, it drives the movable frame 400 to move away from the rotating disk 300. The motor is fixedly mounted within the cabinet 100, and one end of the lead screw 130 is fixedly connected to the motor's output shaft.

[0052] In this embodiment, a sensor is provided on the second slider 642 to sense the contact state between the first inclined surface and the locking block 621. A controller is provided on the motor to control the motor to drive the lead screw 130 to rotate forward when the sensor detects contact between the first inclined surface and the locking block 621. The controller is also used to control the motor to drive the lead screw 130 to rotate in the reverse direction when the sensor detects that the first inclined surface and the locking block 621 have disengaged.

[0053] In this embodiment, the installation mechanism further includes an adjustment assembly, which includes a rack 410, a gear 411, and a splined rod 500. The splined rod 500 is vertically arranged and rotatably mounted within the cabinet 100. A slidable energy storage cylinder 660 is mounted on the splined rod 500, and the energy storage cylinder 660 and the splined rod 500 rotate synchronously. A spline groove is formed inside the energy storage cylinder 660, and the splined rod 500 and the spline groove cooperate with each other so that the splined rod 500 drives the energy storage cylinder 660 to rotate synchronously.

[0054] Gear 411 is fixedly mounted on splined rod 500, and is coaxial with splined rod 500. Rack 410 is fixedly mounted on movable frame 400, and is arranged along a first direction. Gear 411 and rack 410 mesh. When movable frame 400 moves toward the rotating disk 300, rack 410 drives splined rod 500 to rotate forward via gear 411, causing accumulator 660 to rotate relative to torque cylinder 650, and spring 670 to store power. When movable frame 400 moves away from rotating disk 300, rack 410 drives splined rod 500 to rotate in the opposite direction via gear 411, causing accumulator 660 to rotate relative to torque cylinder 650, and spring 670 to release power.

[0055] Working process: In the initial state of the equipment, the locking block 621 is disengaged from the locking groove 612, and the friction block 420 is not in contact with the rotating disk 300 and is in a separated state. Under the elastic force of the second spring 645 and the third spring 643, the steel rope 641 remains taut, the pawl 647 and the ratchet 631 mesh with each other, and the second slider 642 is partially in the second sliding groove 613 and partially in the locking groove 612.

[0056] According to the height of the gas cylinder 200 to be placed, the staff manually adjusts the overall height of the lifting frame, and then inserts the connecting pin into the aligned first positioning hole 140 and second positioning hole 615 to complete the height positioning and fixing of the lifting frame.

[0057] After positioning, place the gas cylinder 200 on the bearing surface of the rotating disk 300, and simultaneously confine the gas cylinder 200 within the U-shaped opening area formed by the crossbar, the first stop bar, and the second stop bar. Since the rotating disk 300 has the ability to rotate freely, the operator can rotate the gas cylinder 200. The bottom of the gas cylinder 200 drives the rotating disk 300 to rotate synchronously through friction, significantly reducing the operational resistance for aligning the gas cylinder 200 and facilitating the precise connection and installation of the gas cylinder 200's outlet with the pipeline 110 interface.

[0058] After the gas cylinder 200 is aligned, pull up the locking block 621 at the end of the strap 620 to pull the strap 620 out of the mounting slot 611 by an appropriate length. During the pulling out process, the torque cylinder 650 rotates relative to the accumulator cylinder 660, causing the built-in spring 670 to complete the energy storage. At the same time, since the strap 620 and the one-way shaft 630 are in frictional contact, pulling the strap 620 outward will cause the one-way shaft 630 to rotate in the forward direction. Relying on the one-way engagement and limiting structure of the pawl 647 and the ratchet 631, the one-way shaft 630 cannot rotate in the reverse direction. Therefore, the strap 620 will not automatically retract into the mounting slot 611 under the action of the spring 670's rebound force.

[0059] After the strap 620 is pulled out to the appropriate length to fit the gas cylinder 200, the locking block 621 is inserted into the slot 612. During the insertion of the locking block 621 into the slot 612, it contacts and adheres to the first inclined surface of the slot 612, and pushes the second slider 642 to slide towards the connecting frame 610, thereby loosening the taut steel cable 641.

[0060] After the steel rope 641 is slack, the first slider 644, under the elastic reset action of the second spring 645, slides away from the connecting frame 610, tightening the steel rope 641 again and restoring it to a taut state. During the displacement of the first slider 644, the guide engagement between the slide rod 649 and the first inclined groove 646 drives the two sets of pawls 647 to move closer to each other along a third direction, so that the originally meshed pawls 647 and ratchet teeth 631 are completely separated and unlocked, and the one-way shaft 630 is released from its limit and can rotate freely in both directions. At this time, the spring 670 releases the stored torque, automatically retracting the excess strap 620 outside the mounting groove 611, so that the strap 620 fits tightly against and tightens the outer wall of the gas cylinder 200, completing the binding and fixing operation of the gas cylinder 200.

[0061] When it is necessary to disassemble the gas cylinder 200, simply pull the locking block 621 out of the locking slot 612. During the process of pulling out the locking block 621, the second slider 642 gradually resets, and the first slider 644 is pulled back to reset synchronously by the steel cable 641. Before the locking block 621 is completely pulled out, the pawl 647 and the ratchet 631 can automatically engage and reset again, relocking the one-way shaft 630, so that the strap 620 will not retract under the action of the spring 670, maintaining the current pulled-out length without the need for repeated adjustments.

[0062] When binding the next set of gas cylinders 200, the device can be flexibly adapted to the diameter of the cylinders 200: if the diameter of the cylinder 200 to be fixed is smaller than that of the previous set of cylinders 200, simply re-engage the locking block 621 into the locking slot 612, and the spring 670 will automatically retract the excess binding strap 620 to complete the clamping. If the diameter of the cylinder 200 to be fixed is larger than that of the previous set of cylinders 200, the binding strap 620 can be pulled outward again to a suitable length, and then the locking block 621 can be engaged into the locking slot 612, causing the excess binding strap 620 to automatically retract and tighten. Through the adaptive telescopic characteristics of the binding strap 620, it can accommodate various cylinders 200 with different diameters, significantly improving the adaptability and versatility of the equipment.

[0063] Meanwhile, the equipment has an automatic locking function for the rotating disk 300: when the card block 621 is inserted into the card slot 612 and contacts the first inclined surface, the sensor detects the contact signal and feeds it back to the controller. The controller starts the motor to drive the lead screw 130 to rotate in the forward direction. The lead screw 130 drives the movable frame 400 to move closer to the rotating disk 300 until the friction block 420 is in close contact with the rotating disk 300, thereby locking and limiting the rotation of the rotating disk 300.

[0064] Conversely, when the card block 621 is pulled out of the card slot 612 and loses contact with the first inclined surface, the sensor detects a separation signal, and the controller controls the motor to drive the lead screw 130 to rotate in the opposite direction. The lead screw 130 drives the movable frame 400 to move away from the rotating disk 300, so that the friction block 420 is completely separated from the rotating disk 300, and the rotation restriction on the rotating disk 300 is released.

[0065] This structural design enables differentiated control under various working conditions: During the loading and unloading of gas cylinder 200, the rotating disk 300 can rotate freely, allowing workers to easily adjust the angle and position of the gas cylinder 200 and accurately connect the pipeline 110. After the gas cylinder 200 is fixed, the rotating disk 300 is locked in place, effectively preventing the rotating disk 300 from rotating due to equipment vibration, ensuring the stability of the fixed state of the gas cylinder 200, preventing the pipeline 110 connection position from shifting or being damaged due to force, and protecting the integrity of the pipeline 110 connection structure.

[0066] In addition, the displacement of the movable frame 400 can synchronously adjust the torque of the spring 670: when the movable frame 400 moves towards the rotating disk 300, the spline rod 500 is driven to rotate in the forward direction through the transmission cooperation of the rack 410 and the gear 411, which drives the accumulator 660 to rotate relative to the torque cylinder 650, so that the spring 670 stores power a second time and increases the torque, effectively improving the clamping force of the strap 620 on the gas cylinder 200 and ensuring the fixation is reliable.

[0067] When the movable frame 400 moves away from the rotating disk 300, the rack 410 and gear 411 drive the spline rod 500 to rotate in the opposite direction, which in turn drives the accumulator 660 to rotate in the opposite direction relative to the torque cylinder 650, thereby unloading the spring 670 and reducing the torque. During the loading and unloading of the gas cylinder 200 and the manual pulling of the strap 620, the torque of the spring 670 is relatively low, which can significantly reduce the manual pulling force and make the stretching and adjustment of the strap 620 easier and less strenuous.

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.
