Description

Technical Field

[0001] The utility model relates to the technical field of flame preheating device design, in particular to a flame preheating device. Background Art

[0002] An automotive flame preheating device is a device used to preheat an engine in a cold environment. It mainly generates heat by burning fuel to heat the engine coolant or engine oil, so that the engine can be smoothly started under low-temperature conditions and reduce the wear of the engine during cold start. The flame preheating device usually uses fuel (such as diesel or gasoline) as fuel and generates heat by combustion. These heats are used to preheat the engine coolant or engine oil to make it reach the suitable starting temperature range. However, in the prior art, the existing common flame preheating device is directly connected to the connection structure of the vehicle by threads. During the driving process of the vehicle, vibrations often occur. Long-term vibrations are likely to cause the connection between the threads of the flame preheating device to become loose, resulting in the leakage of the flame and causing the vehicle to catch fire. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the defect that the connection between the threads of the flame preheating device is loose in the prior art, and to provide a flame preheating device.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: a flame preheating device, including a preheating mechanism, a threaded column is arranged inside the preheating mechanism, a flame outlet pipe is fixedly connected to the bottom of the threaded column, a flame pipe is fixedly connected to one end of the preheating mechanism, a connecting pipe is fixedly connected to one end of the flame pipe, a connecting head is fixedly connected to one end of the connecting pipe, and a fixing mechanism is arranged on one side of the preheating mechanism.

[0006] The technical effect of adopting the above further scheme is that when the preheating mechanism connected by threads is buckled on the inner walls of the left clamping block and the right clamping block through the clamping block, it can prevent vibrations from often occurring during the driving process of the vehicle, and the connection between the threads of the preheating mechanism will become loose after a long time.

[0007] As a preferred embodiment, groove holes are formed on the surfaces of the left clamping block and the right clamping block, and the groove holes formed on the surfaces of the left clamping block and the right clamping block penetrate through the surface of the connecting rod.

[0008] The technical effect of adopting the above further scheme is that the left clamping block and the right clamping block can rotate on the surface of the connecting rod.

[0009] As a preferred embodiment, there are two telescopic springs. One end of each telescopic spring is fixedly connected to the surface of the connecting plate, and the other ends of the two telescopic springs are respectively fixedly connected to the surfaces of the left clamping block and the right clamping block.

[0010] The technical effect of adopting the above further solution is that: through the elasticity of the telescopic springs, the left clamping block and the right clamping block on both sides of the telescopic springs are applied with inward acting forces, so that the left clamping block and the right clamping block are tightly buckled on the surface of the clamping block.

[0011] As a preferred embodiment, the hexagonal block fixedly connected to one end of the clamping block is rotatably connected to the cylindrical surface at the top of the threaded column.

[0012] The technical effect of adopting the above further solution is that: when the preheating mechanism is threadedly connected to other structures, the preheating mechanism rotates, and the hexagonal block fixedly connected to one end of the clamping block can adjust its own angle so that the clamping block is buckled in the left clamping block and the right clamping block.

[0013] As a preferred embodiment, a plurality of round holes are formed on the surface of the flame outlet pipe.

[0014] The technical effect of adopting the above further solution is that: the round holes on the surface of the flame outlet pipe allow the flame to emerge from the plurality of round holes, which can disperse the intensity of the flame.

[0015] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0016] In the present utility model, through the design of the fixing mechanism, when the preheating mechanism is threadedly connected to other structures, the inner walls of the left clamping block and the right clamping block are buckled on the surface of the clamping block, fixing the rotation direction of the preheating mechanism, prohibiting the self-rotation caused by the vibration of the threaded column, that is, preventing the loosening of the connection between the threads of the preheating mechanism due to long-term vibration, and avoiding the consequence of vehicle spontaneous combustion caused by flame ejection.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] As Figures 1-4 shown, the present invention provides a technical solution: a flame preheating device, including a preheating mechanism 1. A threaded column 2 is arranged inside the preheating mechanism 1. Threads are provided on the surface of the threaded column 2, so that the whole preheating mechanism 1 is threadedly connected to the connecting structure. The bottom of the threaded column 2 is fixedly connected to a flame outlet pipe 3. A plurality of round holes are opened on the surface of the flame outlet pipe 3. One end of the preheating mechanism 1 is fixedly connected to a flame pipe 4. One end of the flame pipe 4 is fixedly connected to a connecting pipe 5. The connecting pipe 5 is made of rubber. One end of the connecting pipe 5 is fixedly connected to a connector 6, so that the connection between the flame pipe 4 and the connector 6 has flexibility, which is convenient for the connection between the preheating mechanism 1 and the connector 6 and other connecting structures. Threaded grooves are opened on the surface of the connector 6, and the connector 6 is threadedly connected to other structures.

[0026] In this embodiment, the round holes on the surface of the flame outlet pipe 3 are arranged at the flame outlet, and there are two layers of high round holes, arranged on the surface of the flame outlet pipe 3, so that the flame emerges from the plurality of round holes, which can disperse the intensity of the flame and at the same time expand the area of flame spraying, so as to heat up the diesel as much as possible.

[0027] Embodiment 2

[0028] As Figures 1-4As shown, the fixing mechanism 7 includes a clamping block 71. One end of the clamping block 71 is fixedly connected to a hexagonal block that is rotatably connected to the cylindrical surface at the top of the threaded column 2. On one side of the clamping block 71, there is a connecting plate 72. On the surface of the connecting plate 72, there are two telescopic springs 73 fixedly connected. One end of each telescopic spring 73 is fixedly connected to the surface of the connecting plate 72, and the other ends of the two telescopic springs 73 are respectively fixedly connected to the surfaces of the left clamping block 74 and the right clamping block 75. At one end of the connecting plate 72, there is a left clamping block 74. Groove holes are formed on the surfaces of both the left clamping block 74 and the right clamping block 75, and the groove holes formed on the surfaces of the left clamping block 74 and the right clamping block 75 penetrate through the surface of the connecting rod 76. On one side of the left clamping block 74, there is a right clamping block 75. One end of the connecting plate 72 is fixedly connected to a connecting rod 76.

[0029] In this embodiment, when the preheating mechanism 1 is threadedly connected to other structures, the preheating mechanism 1 will rotate. The hexagonal block fixedly connected to one end of the clamping block 71 can rotate on the cylindrical surface at the top of the threaded column 2 to adjust its own angle so that the clamping block 71 is accurately buckled on the inner walls of the left clamping block 74 and the right clamping block 75, preventing the situation of misalignment of the clamping block 71.

[0030] Working principle:

[0031] As Figures 1-4 shown, by designing the fixing mechanism 7, rotate the preheating mechanism 1 to threadedly connect the threaded column 2 with other connecting structures. After determining that the threaded connection is stable, rotate the hexagonal block connected to the top of the threaded column 2 so that one end of the clamping block 71 is aligned with the inner walls of the left clamping block 74 and the right clamping block 75. Press one end of the left clamping block 74 and the right clamping block 75 towards the end of the clamping block 71. The telescopic springs 73 stretch between the left clamping block 74, the right clamping block 75 and the connecting plate 72. At the same time, the elasticity of the telescopic springs 73 applies an inward acting force to the left clamping block 74 and the right clamping block 75 on both sides of the telescopic springs 73, so that the left clamping block 74 and the right clamping block 75 are tightly buckled on the surface of the clamping block 71. Then, fixedly connect the fixing mechanisms 7 on the other side of the hexagonal block connected to the top of the threaded column 2 in turn.

[0032] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
