Description

Technical Field

[0001] This utility model relates to the field of heater technology, specifically to a special vehicle heater. Background Technology

[0002] Special vehicles, as a category of vehicles with special purposes, encompass various types such as tank trucks, dedicated water purification vehicles, and monitoring vehicles equipped with fixed special instruments and equipment for professional work. They play a crucial role in many fields. For example, in the military field, special vehicles include large military engineering vehicles, large military transport vehicles, and large military buses, which perform various important tasks. In frigid conditions, the normal operation of special vehicles faces severe challenges.

[0003] In special vehicle applications, heaters typically use a bolt-fixed installation design, requiring precise drilling at pre-set locations on the vehicle body to match the bolt specifications. Installers usually first mark the location and pre-drill holes, then use a torque wrench to tighten multiple bolts in stages. During this process, the fit between the heater and the vehicle frame needs to be repeatedly adjusted to avoid stress concentration. This not only makes the installation process time-consuming and labor-intensive, but also makes it difficult for workers to disassemble and reassemble the heater without tools. Therefore, those skilled in the art provide a special vehicle heater to solve the problems mentioned in the background art. Utility Model Content

[0005] This utility model provides the following technical solution: a special vehicle heater, including a mounting plate, two sets of pipes are symmetrically fixedly connected inside the mounting plate, the outer ends of the two sets of pipes are connected to connecting pipes through flanges, and the inner ends of the two sets of pipes are fixedly connected to heaters. The rear surface of the mounting plate is attached to a vehicle frame, and the mounting plate drives the pipes and heaters to slide within the vehicle frame. A connecting component is provided between the mounting plate and the vehicle frame, and the mounting plate is connected to the vehicle frame through the connecting component. Limiting components are provided on the outer walls of the pipes and connecting pipes, and the pipes are connected to the connecting pipes through the limiting components.

[0006] As a preferred embodiment of the above technical solution, the connecting assembly includes movable compartments symmetrically and fixedly connected to the outer walls of the frame on both sides of the mounting plate. Each of the two movable compartments has a rotating rod rotatably connected within it. A torsion spring is wound around the surface of the rotating rod in each of the two movable compartments. A mounting seat is attached to the end of each of the two movable compartments facing away from the mounting plate. The rear end surfaces of each of the two mounting seats are fixedly connected to the surface of the mounting plate. Both mounting seats are slidably connected to the rotating rod. Limit grooves are formed within each of the two mounting seats. Limit blocks are fixedly connected to the outer walls of each of the two rotating rods. Rubber blocks are fixedly connected to the front end surfaces of each of the two mounting seats. Four sets of positioning grooves are symmetrically formed on the surfaces of the two mounting plates. Positioning posts are fixedly connected to the frame surfaces in each of the four positioning grooves.

[0007] As a preferred embodiment of the above technical solution, sealing rings are glued to the side surface of the mounting plate facing the vehicle frame, and the rear ends of the sealing rings are tightly fitted to the outer wall of the vehicle frame.

[0008] As a preferred embodiment of the above technical solution, anti-slip textures are provided on the front and rear surfaces of both sets of limiting blocks, and both sets of limiting blocks are rectangular in shape.

[0009] As a preferred embodiment of the above technical solution, the limiting component includes two sets of guide posts symmetrically fixedly connected to the outer walls of the two sets of pipes on both sides. A connecting pipe is slidably connected to each of the two sets of guide posts. A fixing seat is fixedly connected to the surface of each of the two sets of pipes facing away from the mounting plate. A sliding groove is formed on the front surface of each of the two sets of fixing seats. A slider is slidably connected in each of the two sets of sliding grooves. The bottom surface of each of the two sets of sliders is fixedly connected to the outer wall of the connecting pipe. A guide groove is formed inside each of the two sets of fixing seats facing away from the sliding groove. An insert is slidably connected in each of the two sets of guide grooves.

A pull rod is fixedly connected to the surface of each of the two sets of inserts facing away from the slot, and the pull rod is slidably connected to the fixing seat. A spring is wound around the surface of the pull rod in each of the two sets of guide grooves.

[0010] As a preferred embodiment of the above technical solution, one end of the spring is welded to the inner wall of the guide groove, and the other end of the spring is welded to the top of the insert block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a limiting block to drive a rotating rod to rotate within the movable chamber, aligning the limiting block with the limiting groove. Then, a mounting plate drives the heater to slide into the frame, and the mounting plate causes the positioning groove to fit onto the positioning post, thus limiting the heater's position. The mounting base then fits into the movable chamber and onto the rotating rod. The restoring force of the torsion spring drives the rotating rod to reset and rotate within the movable chamber, causing the limiting block to misalign with the limiting groove. Simultaneously, one end of the limiting block fits into a rubber block, thus fixing the heater. By rotating the limiting block to align with the mounting base, the mounting plate drives the mounting base to slide off the rotating rod, facilitating the assembly and disassembly of the heater without the need for tools, thus improving the efficiency of heater assembly and disassembly.

[0013] 2. In this utility model, the connecting pipe is sleeved on the guide post and fits against the pipe. At this time, the slider slides into the groove simultaneously and aligns the slot with the spring. Then, the spring's restoring force drags the slot back to its original position in the guide groove and slides the insert into the slot, thereby achieving the purpose of pre-fixing the connecting pipe and aligning the connecting pipe with the flange hole in the pipe, which facilitates the workers to make flange connections between the pipe and the connecting pipe.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-6 As shown, this utility model provides a technical solution: a special vehicle heater, including a mounting plate 1, two sets of pipes 2 are symmetrically fixedly connected inside the mounting plate 1, the outer ends of the two sets of pipes 2 are connected to connecting pipes 3 through flanges, the inner ends of the two sets of pipes 2 are fixedly connected to heaters 4, the rear end surface of the mounting plate 1 is attached to a vehicle frame 5, the mounting plate 1 drives the pipes 2 and heaters 4 to slide inside the vehicle frame 5, a connecting component 6 is provided between the mounting plate 1 and the vehicle frame 5, the mounting plate 1 is connected to the vehicle frame 5 through the connecting component 6, and a limiting component 7 is provided on the outer wall of both the pipes 2 and the connecting pipes 3, the pipes 2 are connected to the connecting pipes 3 through the limiting component 7.

[0023] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the connecting assembly 6 includes movable compartments 61 symmetrically fixedly connected to the outer walls of the frame 5 on both sides of the mounting plate 1. Rotating rods 62 are rotatably connected within each of the two movable compartments 61. Torque springs 63 are wound around the surfaces of the rotating rods 62 in both movable compartments 61. Mounting seats 64 are attached to the surfaces of the two movable compartments 61 facing away from the mounting plate 1. The rear surfaces of the two mounting seats 64 are fixedly connected to the surface of the mounting plate 1. The two mounting seats 64 are slidably connected to the rotating rods 62. Limiting grooves 65 are provided within each of the two mounting seats 64. Limiting blocks 66 are fixedly connected to the outer walls of the two rotating rods 62. Rubber blocks 67 are fixedly connected to the front surfaces of the two mounting seats 64. Four positioning grooves 68 are symmetrically provided on the surfaces of the two mounting plates 1. Positioning posts 69 are fixedly connected to the surfaces of the frame 5 in each of the four positioning grooves 68.

[0024] Specifically, the limiting block 66 drives the rotating rod 62 to rotate within the movable chamber 61, aligning the limiting block 66 with the limiting groove 65. Then, the mounting plate 1 drives the heater 4 to slide into the frame 5, and the mounting plate 1 causes the positioning groove 68 to fit onto the positioning post 69, thus limiting the heater 4. The mounting seat 64 then fits into the movable chamber 61 and onto the rotating rod 62. The restoring force of the torsion spring 63 drives the rotating rod 62 to reset and rotate within the movable chamber 61, causing the limiting block 66 to misalign with the limiting groove 65. Simultaneously, one end of the limiting block 66 fits into the rubber block 67, thus fixing the heater 4. Finally, by rotating the limiting block 66 to align with the mounting seat 64, the mounting plate 1 drives the mounting seat 64 to slide off the rotating rod 62, facilitating the disassembly and assembly of the heater 4 without the need for tools, thus improving the efficiency of disassembly and assembly.

[0025] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, sealing rings are glued to the side surface of the mounting plate 1 facing the frame 5, and the rear ends of the sealing rings are tightly fitted to the outer wall of the frame 5.

[0026] Specifically, this implementation can improve the sealing between the mounting plate 1 and the frame 5, preventing mosquitoes from entering the frame 5 through the gap between the mounting plate 1 and the frame 5 and causing bites to the staff inside the frame 5.

[0027] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, both sets of limiting blocks 66 have anti-slip textures on their front and rear surfaces, and both sets of limiting blocks 66 are rectangular in shape.

[0028] In practice, this design facilitates the rotation of the limit block 66 by the staff, making it less likely for the staff to slip when rotating the limit block 66, thereby improving the stability of the staff's use of the limit block 66.

[0029] As one implementation method in this embodiment, please refer to Figures 1-5As shown, the limiting component 7 includes two sets of guide posts 71 symmetrically fixedly connected to the outer walls of the two sets of pipes 2 on both sides. A connecting pipe 3 is slidably connected to each of the two sets of guide posts 71. A fixing seat 72 is fixedly connected to the surface of each of the two sets of pipes 2 away from the mounting plate 1. A sliding groove 73 is opened on the front surface of each of the two sets of fixing seats 72. A slider 74 is slidably connected in each of the two sets of sliding grooves 73. The bottom surface of each of the two sets of sliders 74 is fixedly connected to the outer wall of the connecting pipe 3. A guide groove 75 is opened in the interior of each of the two sets of fixing seats 72 away from the sliding groove 73. An insert 76 is slidably connected in each of the two sets of guide grooves 75. A slot 77 is opened in the slider 74 and the fixing seat 72 corresponding to the outer surface of each of the two sets of inserts 76. A pull rod 78 is fixedly connected to the surface of each of the two sets of inserts 76 away from the slot 77, and the pull rod 78 is slidably connected to the fixing seat 72. A spring 79 is wound on the surface of the pull rod 78 in each of the two sets of guide grooves 75.

[0030] Specifically, the pull rod 78 is pulled away from the direction of pipe 2, causing the pull rod 78 to drive the insert 76 to slide in the guide groove 75 and compress the spring 79. Then, the connecting pipe 3 is fitted onto the guide post 71 and fits against the pipe 2. At this time, the slider 74 slides into the slide groove 73 simultaneously and aligns the slot 77 with the spring 79. Then, the pull rod 78 is released, and the restoring force of the spring 79 is used to drag the slot 77 back to its original position in the guide groove 75, and the insert 76 slides into the slot 77, thereby achieving the purpose of pre-fixing the connecting pipe 3 and aligning the connecting pipe 3 with the flange hole in the pipe 2, which facilitates the flange connection between the pipe 2 and the connecting pipe 3 by the operator.

[0031] As one implementation method in this embodiment, please refer to Figures 1-5 As shown, one end of the spring 79 is welded to the inner wall of the guide groove 75, and the other end of the spring 79 is welded to the top of the insert block 76.

[0032] Specifically, the two ends of the spring 79 can be fixed to prevent the spring 79 from rebounding due to the restoring force generated by the compression of the insert block 76, and thus avoid it from hitting the inner wall of the guide groove 75 and the inner wall of the insert block 76, which would cause noise pollution.

[0033] Working principle: First, the limiting block 66 drives the rotating rod 62 to rotate within the movable chamber 61. Simultaneously, the rotating rod 62 drives the torsion spring 63 to twist until the limiting block 66 rotates to align with the limiting groove 65. Then, the mounting plate 1 drives the heater 4 to slide into the frame 5, and the mounting plate 1 drives the positioning groove 68 to fit onto the positioning post 69, thereby achieving the purpose of limiting the heater 4. Then, the mounting seat 64 fits into the movable chamber 61 and fits onto the rotating rod 62. At this time, the restoring force of the torsion spring 63 drives the rotating rod 62 to reset and rotate within the movable chamber 61, causing the limiting block 66 to misalign with the limiting groove 65. At the same time, one end of the limiting block 66 fits into the rubber block 67, thereby fixing the heater 4. Then, by rotating the limiting block 66 to align with the mounting seat 64, the mounting plate 1 drives the mounting seat 64 to slide off the rotating rod 62, thus facilitating the disassembly and assembly of the heater 4 by the staff.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
