Description

Technical Field

[0001] This utility model relates to the field of anti-tipping technology, and in particular to a multifunctional anti-tipping device for acetylene cylinders. Background Technology

[0002] In the storage and transportation of high-pressure gas cylinders such as acetylene cylinders, the reliability of anti-tipping devices directly affects operational safety. Currently, the mainstream technology uses chain winding for limiting the position. This approach has the following problems: after the cylinder is placed, an additional chain locking action is required. If the operation is neglected (such as not fully tightening the bolts), the fixation may fail, leading to a tipping accident. Furthermore, existing anti-tipping devices mostly use fixed metal frame structures, which are bulky, occupy a large amount of space, and are inconvenient to move. In particular, when adjusting the position, the entire device needs to be moved, which is time-consuming and labor-intensive.

[0003] Therefore, this application provides a multifunctional anti-tipping device for acetylene cylinders to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a multifunctional anti-tipping device for acetylene cylinders, which aims to solve the problem that after the cylinder is placed, an additional chain action is required, and if the operation is neglected, the fixation may fail, leading to a tipping accident.

[0005] To achieve the above objectives, this application provides the following technical solution: a multifunctional acetylene cylinder anti-tipping device, comprising a placement plate, support rods, and connecting parts. The top surface of the placement plate is provided with two sets of symmetrical support rods, which are connected by arc-shaped connecting parts. Multiple sets of connecting parts are arranged vertically. Protrusions are provided on the inner wall of the support rods, and limit plates are hinged to the protrusions. The limit plates are arc-shaped and are connected to the connecting parts through a fixing mechanism.

[0006] The support rod is equipped with a detachable movable component.

[0007] Preferably, a torsion spring is provided at the connection between the limiting plate and the protrusion.

[0008] Preferably, the fixing mechanism includes a locking element, a sliding element, a spring, and a locking pin. The locking element is L-shaped and has a threaded hole that communicates with each other on its top surface. A sliding element is provided at the end of the limiting plate. The bottom surface of the sliding element is slidably connected to the top surface of the connecting element. A sliding groove is provided on the top surface of the sliding element. A locking pin is slidably connected in the sliding groove. The cross-section of the locking pin is an isosceles trapezoid. A set of springs is press-fitted between the locking pin and the sliding groove, and the end of the locking pin is adapted to the threaded hole.

[0009] Preferably, a set of adjusting bolts is threaded into the threaded hole, and the bottom surface of the adjusting bolts is slidably connected to the retaining pin.

[0010] Preferably, the bottom surface of the slider is provided with a limiting hole that connects to the sliding groove. The limiting hole has a T-shaped cross-section, and a limiting member with a T-shaped cross-section is slidably connected in the limiting hole. The limiting member passes through the spring and is connected to the locking pin.

[0011] Preferably, the movable component includes a docking block, a movable frame, and a plug. The docking block is mounted on the outer wall of the support rod and has a slot on its end face. A wedge-shaped locking block is provided on the inner top surface of the slot. A plug is provided on the end face of the movable frame. The plug is slidably connected in the slot and has a locking groove on its outer wall that matches the locking block.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] In this invention, when the bottle is placed on the placement plate, its own weight pushes the inner wall of the limiting plate, forcing the limiting plate to rotate around the hinge point of the protrusion. Simultaneously, it drives the slider to slide along the connecting piece. When the slider moves to the bottom of the locking piece, the locking pin is squeezed by the top surface of the connecting piece and retracts into the sliding groove. After the slider reaches the threaded hole, the spring instantly releases its elastic force, accurately pushing the isosceles trapezoidal locking pin into the threaded hole, completing the instantaneous locking of the bottle. No secondary operation by the operator is required throughout the process. Rotating the adjusting bolt can press the locking pin to disengage from the threaded hole, releasing the fixed state of the limiting plate. The operation time is reduced by more than 90% compared to the traditional chain disassembly. After the bottle is removed, the limiting plate automatically springs back to the initial position under the action of the torsion spring at the hinge, preparing for the placement of the next bottle, achieving seamless connection of continuous operation.

[0014] This utility model enables convenient movement of the gas cylinder device through the quick assembly of the plug-in docking block and the mobile frame. After the position adjustment is completed, the mobile component can be separated, which ensures both compactness in use and flexibility in transportation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Reference Figure 1-9 The multifunctional acetylene cylinder anti-tipping device shown includes a placement plate 1, support rods 2, connecting parts 3, limiting plates 4, fixing mechanisms, and moving components. Two sets of symmetrical support rods 2 are provided on the top surface of the placement plate 1, and the two sets of support rods 2 are connected by arc-shaped connecting parts 3. To fix the cylinder body on the placement plate 1, protrusions 200 are provided on the outer wall of the support rods 2. Two protrusions 200 are arranged as a group (symmetrically arranged vertically), and at least four groups are provided (e.g., ...). Figure 3As shown, an arc-shaped limiting plate 4 is hinged to the protrusion 200. The end of the limiting plate 4 is connected to the connector 3 through a fixing mechanism, thereby limiting the bottle body. In order to improve the practicality of the anti-tipping device, this embodiment is provided with a set of movable components that can be used separately from the support rod 2 so as to move the anti-tipping device. After being moved to a suitable position, the movable components are separated to save placement space.

[0028] As one embodiment of this example, the fixing mechanism is as follows: a slider 7 is provided at the end of the limiting plate 4, a sliding groove 700 is provided on the top surface of the slider 7, and a set of locking pins 10 with an isosceles trapezoidal cross section is slidably connected in the sliding groove 700. In order to allow the locking pins 10 to slide up and down in the sliding groove 700, a set of springs 9 are press-fitted between the locking pins 10 and the sliding groove 700.

[0029] Two sets of symmetrical clips 5 are provided on the top surface of the connector 3. The clips 5 are L-shaped and have threaded holes 500 on their top surfaces. The threaded holes 500 are compatible with the aforementioned locking pins 10. Therefore, when in use, the bottle body is pressed against the outer wall of the limiting plate 4, and then the limiting plate 4 rotates around the protrusion 200 as the center, causing the slider 7 to slide on the connector 3 and the locking pins 10 to be engaged in the threaded holes 500, thereby achieving the purpose of fixing the bottle body.

[0030] As one implementation method in this embodiment, in order to facilitate the limiting of the contact fixing mechanism and separate the locking pin 10 from the threaded hole 500, a set of adjusting bolts 6 are threadedly connected in the threaded hole 500. Therefore, by rotating the adjusting bolts 6, the bottom surface of the adjusting bolts 6 abuts against the locking pin 10 and presses the locking pin 10 downward, so that the locking pin 10 leaves the threaded hole 500, thereby releasing the limiting relationship between the sliding member 7 and the locking member 5.

[0031] As one embodiment of this invention, in order to improve the stability of the locking pin 10 when sliding, a limiting hole 701 with a T-shaped cross section is provided on the bottom surface of the slide 7. The limiting hole 701 is connected to the slide groove 700. A limiting member 8 with a T-shaped cross section is slidably connected in the limiting hole 701. The vertical rod of the limiting member 8 passes through the spring 9 and is threadedly connected to the bottom of the locking pin 10.

[0032] As one embodiment of this invention, in order to allow the limiting plate 4 to reset after the bottle body leaves the anti-tipping device after the limiting member 7 and the locking member 5 are released, a torsion spring is provided at the hinge point between the limiting plate 4 and the protrusion 200.

[0033] As one embodiment of this invention, the moving component has at least two sets of docking blocks 11 on the outer wall of each set of support rods 2, and slots 110 on the outer wall of the docking blocks 11. Furthermore, the moving frame 12 (such as...) Figure 8 , 9The end of the plug 13 is provided with a set of plugs 13. In order to enable the plug 13 to be quickly spliced ​​after being inserted into the slot 110, a wedge-shaped card block is provided on the inner top surface of the slot 110, and a card groove adapted to the card block is provided on the outer wall of the plug 13. After the plug 13 is inserted into the slot 110, the support rod 2 flips down to make the card groove and the card block engage to complete the splicing purpose.

[0034] The working principle of this utility model is as follows: The bottle is placed on the placement plate 1, and the outer wall of the bottle is pressed against the inner end of the limiting plate 4. As the bottle moves inward, the limiting plate 4 rotates on the protrusion 200. During this process, the slider 7 at the end of the limiting plate 4 slides on the top surface of the connector 3, and the slider 7 moves to the bottom of the locking piece 5. When the locking pin 10 first contacts the locking piece 5, the inclined surface of the locking pin 10 automatically presses the spring 9 in the slide groove 700 downward. After moving to the threaded hole 500, the locking pin 10 is pushed out and inserted into the threaded hole 500 under the action of the spring 9 to achieve fixation, thereby limiting the bottle by the limiting plate 4.

[0035] If the bottle needs to be moved, the plug 13 of the moving frame 12 is inserted into the slot 110 of the docking block 11, and the rotating support rod 2 is flipped to make the card block dock with the card slot to complete the assembly. Then the bottle is moved to a different position by the rollers on the moving frame 12.

[0036] When the bottle needs to be removed from the placement plate 1, the adjusting bolt 6 inside the threaded hole 500 is rotated. The adjusting bolt 6 pushes the locking pin 10 out of the threaded hole 500, releasing the connection between the locking pin 10 and the threaded hole 500 (during this process, the locking pin 10 moves downward and drives the limiting member 8 to slide in the limiting hole 701). Then, when the bottle is moved outward, the limiting plate 4 is driven to rotate around the protrusion 200. After the bottle is removed, the limiting plate 4 is reset by the torsion spring.

[0038] Components not described in detail in this article are existing technologies.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
