Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, and in particular to a holding mechanism for gas cylinders. Background Technology

[0002] Road marking machines are widely used in road construction, including roads, highways, parking lots, plazas, and running tracks. Their core function is to efficiently and accurately mark regular restriction lines on flat surfaces, providing constraints, guidance, and warnings. To achieve this marking function, the application of hot-melt paint necessitates the use of a heating device. This heating device typically uses combustible gas (such as propane) as fuel, thus requiring the carrying and secure storage of the fuel in a gas cylinder.

[0003] In related technologies, a common practice for securing a gas cylinder on a marking machine is to weld a fixed metal frame or conduit directly onto the machine body (such as the frame, chassis, or specific components). This welded frame forms a receiving space where the gas cylinder is placed. The structure of the frame itself and the strength of the weld joints restrict the movement of the gas cylinder, thus achieving basic load-bearing and holding functions.

[0004] However, the above-mentioned method of fixing the frame by welding has significant drawbacks. Once the frame is welded, its position and orientation are permanently fixed, and it is impossible to adjust its position or angle according to actual needs (such as equipment counterweight balance adjustment or operating space optimization). Utility Model Content

[0005] The main purpose of this invention is to propose a holding mechanism for gas cylinders, which aims to solve the problem that the existing gas cylinder holding mechanisms of road marking machines cannot be adjusted in any position or angle.

[0006] To achieve the above objectives, this utility model proposes a holding mechanism for gas cylinders, which includes:

[0007] A frame having a receiving space for placing a gas cylinder;

[0008] The fastener includes a first connecting member and a second connecting member that are bent. The first connecting member includes a first bent segment and a second bent segment that are connected to each other. The first bent segment is connected to the periphery of the frame. The second connecting member includes a third bent segment and a fourth bent segment that are connected to each other. The third bent segment and the second bent segment are slidably connected. The fourth bent segment is spaced apart from the first bent segment. The side of the fourth bent segment that faces away from the first bent segment is a first mounting surface.

[0009] In some embodiments, the second bending segment is provided with a plurality of first strip holes at intervals, the plurality of first strip holes extending along the width direction of the second bending segment; the third bending segment is provided with a plurality of second through holes at intervals, the plurality of second through holes corresponding one-to-one with the first strip holes, and the second bending segment and the third bending segment are connected by bolts.

[0010] In some embodiments, the second through hole is a strip hole.

[0011] In some embodiments, a plurality of third strip holes are spaced apart on the fourth bending segment. The third strip holes extend along the length of the fourth bending segment and are used for bolts to pass through, so as to fix the frame to the road marking machine.

[0012] In some embodiments, the frame includes a base plate and a strap. The bearing plane of the base plate is provided with a first column and a second column. The first column and the second column are arranged at intervals relative to each other. The first bent section is connected between the first column and the second column. The strap is connected to the side of the first column and the second column away from the first bent section.

[0013] In some embodiments, the first column is provided with a first connecting segment at the end away from the base plate, and the second column is provided with a second connecting segment at the end away from the base plate. The first connecting segment and the second connecting segment extend along the length direction of the base plate, and the strap has a first end and a second end opposite to each other. The first end is slidably connected to the end of the first connecting segment away from the first column.

[0014] And / or, the second end is slidably connected to the end of the second connecting segment away from the first column.

[0015] In some embodiments, the frame further includes a third column, a fourth column, and a fifth column, wherein the first column, the third column, the fourth column, the fifth column, and the second column are distributed sequentially at intervals along the periphery of the base plate.

[0016] In some embodiments, the frame further includes a mounting plate connected to the first column and the second column, and the first bent section is connected to the first column and the second column through the mounting plate.

[0017] In some embodiments, the base plate includes a second mounting surface opposite to the bearing plane, and the second mounting surface is provided with a plurality of traveling members.

[0018] The beneficial effects of this utility model are as follows: by setting a fixing member including a first connecting member and a second connecting member, wherein the first bent section of the first connecting member is connected to the periphery of the frame, and the third bent section of the second connecting member is slidably connected to the second bent section, the position of the second connecting member relative to the frame can be adjusted. During use, due to the sliding connection structure, the distance between the fourth bent section and the first bent section can be flexibly adjusted to adapt to the clamping requirements of different specifications of railings, pipes, brackets and other installation structures; the first mounting surface of the fourth bent section can be fitted and connected to a flat, curved or other shaped mounting base surface, realizing the multi-scenario adaptability of the gas tank holding mechanism and overcoming the technical problems of the traditional fixing structure having a single size and poor applicability.

[0034] The gas cylinder holding mechanism in this embodiment is mainly used in road marking machines. Specifically, road marking machines typically require a heating device to achieve their marking function and the application of hot-melt paint. This heating device often uses combustible gas (such as propane) as fuel, thus requiring a gas cylinder to be carried and secured. Existing road marking machines generally use a metal frame or conduit welded directly onto the machine to secure the gas cylinder. However, once the frame is welded, its position and orientation are fixed, making it impossible to adjust its position or angle according to actual needs (such as equipment counterweight balance adjustment, operating space optimization, etc.). Therefore, this embodiment proposes a gas cylinder holding mechanism that enables flexible installation and adjustment. Specifically, refer to... Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a holding mechanism for a gas cylinder, the holding mechanism comprising:

[0035] The frame 100 has a receiving space 100a for placing the gas cylinder;

[0036] The fastener 200 includes a first connector 210 and a second connector 220 that are bent. The first connector 210 includes a first bent section 211 and a second bent section 212 that are connected to each other. The first bent section 211 is connected to the periphery of the frame 100. The second connector 220 includes a third bent section 221 and a fourth bent section 222 that are connected to each other. The third bent section 221 and the second bent section 212 are slidably connected. The fourth bent section 222 is arranged at a distance from the first bent section 211. The side of the fourth bent section 222 that faces away from the first bent section 211 is the first mounting surface 222b.

[0037] In this embodiment, the frame 100 is mainly used to place the gas cylinder. Specifically, the frame 100 can be formed by enclosing multiple columns and a base plate 106, creating an internal accommodating space 100a for placing the gas cylinder. At least part of the accommodating space 100a is shaped to fit the shape of the gas cylinder, ensuring that the gas cylinder can be stably placed within it. The frame 100 can be circular, square, or other suitable geometric shapes to accommodate gas cylinders of different sizes. The frame 100 can be made of metal materials such as stainless steel, carbon steel, or aluminum alloy, or non-metallic materials such as high-strength engineering plastics, to meet the corrosion resistance and strength requirements of different usage environments.

[0038] In this embodiment, the fixing member 200 is mainly used to connect the frame 100 and to fix the frame 100 to the desired target object (such as a flat surface, railing, bracket, etc.). The fixing member 200 includes a first connecting member 210 and a second connecting member 220. Specifically, the first connecting member 210 and the second connecting member 220 can be made of profiles such as angle steel, channel steel, and square steel, or manufactured using processes such as plate bending and casting. The first connecting member 210 and the second connecting member 220 can move relative to each other, and the distance can be adjusted through the sliding connection between the third bending section 221 and the second bending section 212. In this way, the frame 100 can be hung on railings of different diameters. An adjustable gap is formed between the first bending section 211 and the fourth bending section 222 to accommodate installation objects of different specifications. The sliding connection can be achieved through guide rails, slides, threaded adjustments, etc., and a locking mechanism can be provided to fix the adjusted position.

[0039] It should be noted that the gas tank holding mechanism in this embodiment is only applied to road marking machines. Of course, in some embodiments, it can also be applied to commercial hotels, restaurants, factories, outdoor spaces, food carts and tricycles used for street vending, and other scenarios where there is a need to move the gas tank.

[0040] During operation, this retaining mechanism can be installed in various ways depending on different installation requirements:

[0041] Taking installation on a railing as an example, firstly, adjust the distance between the first connecting piece 210 and the second connecting piece 220 so that the gap between the first bent section 211 and the fourth bent section 222 is greater than the outer diameter of the railing. At this point, the frame 100 can be hung on the railing through the gap, with the railing located within the clamping space formed by the first bent section 211 and the fourth bent section 222. Then, reduce the gap using a sliding adjustment mechanism to tightly clamp the railing between the first bent section 211 and the fourth bent section 222. Finally, the relative position between the first connecting piece 210 and the second connecting piece 220 can be fixed using bolts, pins, or other locking devices to ensure the connection's firmness and stability.

[0042] Taking installation on a flat wall as an example, the side of the fourth bend segment 222 facing away from the first bend segment 211 serves as the first mounting surface 222b. Screw holes or mounting holes can be pre-drilled on this mounting surface, and then it can be connected to the wall using fasteners such as bolts or expansion bolts. The mounting surface can be designed as a flat surface or a curved surface with a certain curvature to adapt to different shapes of mounting bases. During installation, the mounting surface can be first aligned with the mounting base, the screw hole positions marked, and then the holes drilled before being fixed with bolts.

[0043] The beneficial effects of this utility model's technical solution are as follows: By setting a fixing member 200 including a first connecting member 210 and a second connecting member 220, wherein the first bent section 211 of the first connecting member 210 is connected to the periphery of the frame 100, and the third bent section 221 of the second connecting member 220 is slidably connected to the second bent section 212, the position of the second connecting member 220 relative to the frame 100 can be adjusted. During use, due to the sliding connection structure design, the distance between the fourth bent section 222 and the first bent section 211 can be flexibly adjusted to adapt to the clamping requirements of circular or irregularly shaped installation structures such as railings, pipes, and supports of different specifications; at the same time, the first mounting surface 222b of the fourth bent section 222 can be fitted and connected to a flat, curved, or other shaped mounting base surface, realizing the multi-scenario adaptability of the gas tank holding mechanism. This design overcomes the technical problems of traditional fixing structures having a single size and poor applicability, significantly improving the product's versatility and practicality, reducing the cost of customizing special fixing members 200 for different application scenarios, and facilitating on-site installation and subsequent maintenance and adjustment.

[0044] See Figure 3In this embodiment, the second bending segment 212 is provided with a plurality of first strip holes 212a at intervals, and the plurality of first strip holes 212a extend along the width direction of the second bending segment 212; the third bending segment 221 is provided with a plurality of second through holes 221a at intervals, and the plurality of second through holes 221a correspond one-to-one with the first strip holes 212a; the second bending segment 212 and the third bending segment 221 are connected by bolts.

[0045] In this embodiment, the relative sliding between the first connector 210 and the second connector 220 is achieved through a bolt and a slotted hole. The bolt passes sequentially through the second through hole 221a and the first slotted hole 212a. When not tightened, the bolt can slide within the first slotted hole 212a, allowing the position of the second connector 220 relative to the first connector 210 to be adjusted. Specifically, when the spacing needs to be adjusted, the bolt is loosened, allowing it to slide within the first slotted hole 212a, which moves the third bent section 221 along the second bent section 212. After adjustment to the appropriate position, the bolt is tightened to secure it. The length of the first slotted hole 212a determines the adjustment range, and different hole lengths can be designed according to actual needs.

[0046] See Figure 3 In this embodiment, the second through hole 221a is a strip hole.

[0047] In this embodiment, both the first strip hole 212a and the second through hole 221a are strip holes, and their length directions correspond to each other. This increases the sliding distance, enabling a wider range of adjustment and accommodating the installation needs of more rod sizes. Specifically, when the bolt slides simultaneously within both strip holes, the adjustment range is the sum of the lengths of the two strip holes. Compared to a single strip hole structure, this significantly expands the applicable range, meeting the clamping requirements of installation objects with different diameters, from small pipes to large railings.

[0048] See Figure 2 and Figure 3 In this embodiment, a plurality of third strip holes 222a are spaced apart on the fourth bending section 222. The third strip holes 222a extend along the length direction of the fourth bending section 222 and are used for bolts to pass through so that the frame 100 is fixedly connected to the road marking machine.

[0049] In this embodiment, the third strip-shaped hole 222a further enhances installation flexibility. By adjusting the position of the bolt within the third strip-shaped hole 222a, the position of the frame 100 along the length of the fourth bend 222 can be adjusted, thereby adapting to the installation requirements of different positions on the road marking machine. Specifically, according to the structural layout and center of gravity balance requirements of the marking machine, appropriate bolt hole positions can be selected for fixing, thereby adjusting the position of the air tank and optimizing the overall weight distribution and operational convenience of the equipment.

[0050] See Figure 3 In this embodiment, the frame 100 includes a base plate 106 and a strap 107. The bearing plane 106a of the base plate 106 is provided with a first column 101 and a second column 102. The first column 101 and the second column 102 are arranged at intervals relative to each other. A first bending section 211 is connected between the first column 101 and the second column 102. The strap 107 is connected to the side of the first column 101 and the second column 102 away from the first bending section 211.

[0051] In this embodiment, the strap 107 is used to better secure the gas canister within the frame 100, preventing it from loosening or falling off during use. The strap 107 can be made of an elastic material, such as rubber, elastic webbing, or silicone, possessing good tensile strength and resilience, allowing it to tightly conform to the gas canister surface and provide continuous clamping force. Alternatively, a rigid material, such as metal straps, plastic buckles, or nylon cable ties, can be used to secure the gas canister mechanically. The shape of the strap 107 is adapted to the shape of the gas canister, and can be designed as an arc, ring, or other shape matching the gas canister's contour, ensuring that the strap 107 can evenly distribute the clamping force and effectively prevent displacement of the gas canister under vibration or impact.

[0052] See Figure 3 In this embodiment, the first column 101 has a first connecting section 101a at the end away from the base plate 106, and the second column 102 has a second connecting section 102a at the end away from the base plate 106. The first connecting section 101a and the second connecting section 102a extend along the length direction of the base plate 106, and the strap 107 has a first end and a second end opposite to each other; wherein the first end is slidably connected to the end of the first connecting section 101a away from the first column 101.

[0053] And / or, the second end is slidably connected to the end of the second connecting segment 102a away from the first column 101.

[0054] In this embodiment, the strap 107 can be adjusted in length and tightness by sliding connection with the connecting section. Specifically, the strap 107 can be slidably connected at one end and fixedly connected at the other end, or both ends can be slidably connected. When one end is slidably connected, the effective length of the strap 107 can be changed by adjusting the position of the sliding end; when both ends are slidably connected, the positions of both ends can be adjusted simultaneously, achieving a wider range of length adjustment and more precise centering of the gas tank. The sliding connection can be achieved by setting grooves, guide rails, or holes on the connecting section, and setting corresponding sliders, buckles, or perforated structures at the end of the strap 107. During adjustment, the user can pull the end of the strap 107 to a suitable position according to the size of the gas tank, and then fix it by the locking mechanism to ensure that the strap 107 generates an appropriate clamping force on the gas tank.

[0055] See Figure 2 and Figure 3 In this embodiment, the frame 100 also includes a third column 103, a fourth column 104 and a fifth column 105. The first column 101, the third column 103, the fourth column 104, the fifth column 105 and the second column 102 are distributed sequentially and at intervals along the periphery of the base plate 106.

[0056] In this embodiment, by setting five columns to form a more stable support structure, more comprehensive protection and fixation can be provided for the gas tank. The five columns are spaced apart along the perimeter of the base plate 106 to form a polygonal receiving space 100a, which has better resistance to lateral forces and overall stability compared to a two-column structure. The columns can be connected to each other by crossbeams or connectors to further enhance the rigidity of the frame 100. This multi-column design is suitable for large gas tanks or applications that need to withstand large vibrations and impacts, effectively preventing the gas tank from shaking and displacing under complex working conditions, and improving safety in use.

[0057] See Figure 3 In this embodiment, the frame 100 also includes a mounting plate 108, which is connected to the first column 101 and the second column 102. The first bent section 211 is connected to the first column 101 and the second column 102 through the mounting plate 108.

[0058] In this embodiment, the mounting plate 108 provides a mounting location for the fastener 200, providing a stable connection foundation for the connection between the first bent section 211 and the column. Simultaneously, the mounting plate 108 also provides a blocking effect for the gas cylinder, preventing axial movement or slippage within the frame 100. The mounting plate 108 can be positioned in the middle or upper part of the column, ensuring both the robustness of the fastener 200 connection and effectively limiting the movement of the gas cylinder.

[0059] See Figure 3 In this embodiment, the base plate 106 includes a second mounting surface 108b opposite to the bearing plane 106a, and the second mounting surface 108b is provided with a plurality of walking members 109.

[0060] In this embodiment, the traveling component 109 consists of multiple omnidirectional wheels, for example, three arranged in a triangle to form a stable three-point support structure. Of course, in some embodiments, four omnidirectional wheels may be arranged in a rectangle, or a greater number of omnidirectional wheels may be provided depending on the shape and size of the base plate 106. The omnidirectional wheels can be 360-degree rotating casters, providing excellent steering flexibility. The traveling component 109 facilitates the movement and positioning of the entire gas tank holding mechanism, especially when frequent adjustments to the gas tank position or equipment maintenance are required. Users can easily push and pull the tank without disassembly or reinstallation, greatly improving ease of use and work efficiency.

[0061] This utility model further proposes a road marking machine, including the gas tank holding mechanism of the aforementioned embodiments. The specific structure of this gas tank holding mechanism is the same as described in the above embodiments. Since the road marking machine adopts all the technical solutions of all the above embodiments, it possesses at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here. The road marking machine may include main components such as a frame, a heating device, a marking device, and a feeding system. The gas tank holding mechanism is connected to the frame via its fixing member 200, providing a stable fuel supply to the heating device. The adjustable characteristics of the holding mechanism allow the gas tank to be positioned according to the structural characteristics of the frame and the center of gravity balance requirements, ensuring the stability and ease of operation of the marking machine during operation. Simultaneously, the multi-scenario adaptability of the holding mechanism allows the same marking machine to be applicable to different working environments and installation conditions.

[0062] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
