Description

Technical Field

[0001] The utility model relates to the technical field of oil tank anti-theft, in particular to an anti-theft type engine unit oil tank. Background Art

[0002] Automobile fuel tank is the full name of automobile fuel tank. At present, with the development of automobile industry and the revitalization of domestic automobile industry, the demand for automobile fuel tanks by major automobile manufacturers has shown a clear growth trend. The transportation industry has become more and more perfect, and more and more people are involved in the logistics industry. However, the quality of long-distance transportation personnel is uneven, which also brings many problems. In long-distance transportation, drivers often need to take turns to guard at night for fear of fuel theft. Some drivers even keep guard dogs in the car. This theft has caused great inconvenience and harm to the driver, affecting the driver's normal rest time, and there is a potential risk of fatigue driving.

[0003] After searching, Chinese patent publication number CN111845326B discloses a new type of anti-theft fuel tank, including a fuel tank body, a fuel tank cavity with an upward opening is provided in the fuel tank body, a fuel tank cover is provided on the upper end surface of the fuel tank body, a sealing sliding cover is slidably provided in the fuel tank cavity, the bottom of the sealing sliding cover is filled with fuel, a sealing switch is provided on the left side of the sealing sliding cover, and a spring is fixedly provided on the upper end surface of the sealing sliding cover symmetrically on the left and right. By using the invention and installing the invention in a designated position, the device will start to automatically detect whether the fuel tank flow and the engine flow match. Regardless of whether the car is running or stopped, the device is not affected by whether the vehicle is moving, and real-time monitoring is performed. If the flow is found to be mismatched, the device will remind the driver and automatically cut off the switch to reduce fuel leakage;

[0004] The above patent has the following problems: 1. It is necessary to monitor the oil volume inside the fuel tank in real time, which requires a large amount of power loss; the installation area is large, which affects the filling of the oil volume inside the fuel tank; 2. The alarm will not be triggered until the thief has taken theft measures. There is a certain delay in the alarm, which will cause part of the oil to be stolen. After the theft, there is no corresponding means to prevent the thief from continuing to steal. In view of this, we propose an anti-theft engine unit fuel tank. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an anti-theft engine unit oil tank, which solves the problems raised in the above background technology.

[0012] It can be seen from the above technical solutions that the anti-theft engine unit oil tank provided in the embodiments of this specification has at least the following beneficial effects:

[0013] (1) The utility model switches the positions of the oil pipe and the anti-theft pipe through the anti-theft switching device, thereby realizing the effect of switching between the normal oil filling and anti-theft states of the oil tank. When a thief opens the oil cover to steal oil, since there is no oil in the anti-theft pipe, the thief cannot steal the oil inside the oil tank, thereby realizing the anti-theft effect. The processing device clamps the theft pipe during the theft, thereby preventing the thief from continuing the subsequent theft work, thereby realizing the double anti-theft effect.

[0014] (2) The utility model monitors the anti-theft tube through the air bag. When the air bag is pressurized, the air is squeezed into the alarm chamber. The air pressure pushes the metal plate upward and contacts the metal touch plate. The metal touch plate generates a complete electrical circuit after contacting the metal plate. At this time, the metal touch plate generates an electrical signal. The central control board commands the active motor to operate according to the electrical signal. The output shaft of the active motor drives the anti-theft tube and the oil inlet end to rotate through the worm gear. When the anti-theft tube rotates, it is misaligned with the oil inlet end. During the misalignment, the thief's oil pipe is clamped, and then the thief's tool is clamped inside the anti-theft base, which prevents the thief from continuing the subsequent theft work and achieves the double anti-theft effect.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-Figure 4As shown, an anti-theft type engine unit oil tank includes a box body 1, an anti-theft base 2 is fixedly connected to the box body 1, a sealing turntable 3 is rotatably connected to the bottom of the anti-theft base 2, an oil pipe 4 and an anti-theft pipe 5 are respectively fixedly connected inside the sealing turntable 3, a processing device 6 is arranged on the anti-theft pipe 5, and an anti-theft switching device 7 is arranged inside the anti-theft base 2. An oil inlet end 8 is fixedly connected to the top of the anti-theft base 2, and an oil cap 9 is threadedly connected to the surface of the oil inlet end 8.

[0024] In this embodiment, the anti-theft switching device 7 includes an active motor 71, the end of which is mounted on the surface of the anti-theft base 2, the output shaft of the active motor 71 is connected to a worm 72, the surface of the worm 72 is meshed with a worm wheel 73, the interior of the worm wheel 73 is fixedly connected to a coupling rod 74, and the surface of the coupling rod 74 is fixedly connected to a mounting plate 75. Under normal circumstances, the oil pipe 4 is aligned with the oil inlet end 8. The user can insert the oil pipe into the oil inlet end 8 to replenish the oil into the box body 1 through the oil pipe 4. When the oil tank needs to be protected from theft, the active motor 71 is controlled to operate. The output shaft of the active motor 71 drives the worm gear 73 to rotate through the worm 72. The worm gear 73 drives the mounting plate 75 to drive the oil pipe 4 and the anti-theft pipe 5 on the connecting plate 76 to rotate through the coupling rod 74. After the rotation, the anti-theft pipe 5 replaces the original position of the oil pipe 4. The bottom end of the anti-theft pipe 5 is in a closed state. At this time, the anti-theft pipe 5 is aligned with the oil inlet end 8. When a thief opens the oil cover 9 to steal oil, since there is no oil in the anti-theft pipe 5, the thief will not steal the oil inside the oil tank, thereby achieving the anti-theft effect.

[0025] Furthermore, the surface of the worm 72 is rotatably connected to the inside of the anti-theft base 2, and the top end of the coupling rod 74 is rotatably connected to the inside of the anti-theft base 2. The surfaces of the oil pipe 4 and the anti-theft pipe 5 are fixedly connected with a connecting plate 76, and the surface of the connecting plate 76 is fixedly connected to the mounting plate 75 by bolts.

[0026] Example 2

[0027] See also Figure 1-Figure 4 As shown, the processing device 6 includes an alarm chamber 61 and an airbag 64. The bottom end of the alarm chamber 61 is fixedly connected to the top end of the anti-theft tube 5. The top of the inner wall of the alarm chamber 61 is fixedly connected to a metal touch plate 62. The interior of the alarm chamber 61 is elastically connected to a metal plate 63 through a spring.

[0028] Furthermore, the surface of the airbag 64 is fixedly connected to the inner wall of the anti-theft tube 5, and a through groove is opened inside the anti-theft tube 5. The interior of the airbag 64 is connected to the interior of the alarm chamber 61 through the through groove, and the surface of the metal plate 63 is connected to the inner wall piston of the alarm chamber 61. When the thief inserts the oil pipe into the anti-theft tube 5, the oil pipe will contact and squeeze the air bag 64 in the anti-theft tube 5. The air bag 64 squeezes the internal gas under pressure, and the gas is squeezed into the alarm chamber 61 through the through groove. The air pressure pushes the metal plate 63 to move upward and contact the metal touch plate 62. The metal touch plate 62 generates a complete electrical circuit after contacting the metal plate 63. At this time, the metal touch plate 62 generates an electrical signal, and the central control board commands the active motor 71 to operate according to the electrical signal. The output shaft of the active motor 71 drives the anti-theft tube 5 and the oil inlet end 8 to rotate through the worm 72 meshing with the worm gear 73. When the anti-theft tube 5 rotates, it is misaligned with the oil inlet end 8. During the misalignment, the thief's oil pipe is clamped, and then the thief's tool is clamped inside the anti-theft base 2, which prevents the thief from continuing the subsequent theft work and achieves the double anti-theft effect.

[0029] When the oil tank of an anti-theft engine unit of the utility model is in use, the oil pipe 4 is aligned with the oil inlet end 8 under normal circumstances. The user can insert the oil pipe into the oil inlet end 8 to replenish the oil into the box body 1 through the oil pipe 4. When the oil tank needs to be anti-theft, the active motor 71 is controlled to operate. The output shaft of the active motor 71 drives the worm gear 73 to rotate through the worm 72. The worm gear 73 drives the mounting plate 75 to drive the oil pipe 4 and the anti-theft pipe 5 on the connecting plate 76 to rotate through the coupling rod 74. After the rotation, the anti-theft pipe 5 replaces the original position of the oil pipe 4. The bottom end of the anti-theft pipe 5 is in a closed state. At this time, the anti-theft pipe 5 is aligned with the oil inlet end 8. When a thief opens the oil cover 9 to steal oil, since there is no oil in the anti-theft pipe 5, the thief will not steal the oil inside the oil tank, thereby achieving the anti-theft effect. At the same time, when the thief inserts the oil pipe into the anti-theft pipe 5, the oil pipe will contact and The airbag 64 is squeezed into the anti-theft tube 5. The airbag 64 is pressed against the internal gas, and the gas is squeezed into the alarm chamber 61 through the through groove. The air pressure pushes the metal plate 63 to move upward and contacts the metal touch plate 62. The metal touch plate 62 generates a complete electrical circuit after contacting the metal plate 63. At this time, the metal touch plate 62 generates an electrical signal. The central control board commands the active motor 71 to operate according to the electrical signal. The output shaft of the active motor 71 engages the worm gear 73 through the worm 72 to drive the anti-theft tube 5 and the oil inlet end 8 to rotate. When the anti-theft tube 5 rotates, it is misaligned with the oil inlet end 8. During the misalignment, the effect of clamping the thief's oil pipe is achieved, and then the thief's crime tool is clamped inside the anti-theft base 2, which prevents the thief from continuing the subsequent theft work and achieves the effect of double anti-theft. In addition, when the hollow plate receives the electrical signal at the metal touch plate 62, it can also alarm the user at the same time.
