Description

An anti-theft device suitable for iron fuel tanks of trucks

Technical Field

The utility model relates to the technical field of anti-theft, in particular to an anti-theft device suitable for an iron fuel tank of a truck.

Background Art

The capacity of a truck's fuel tank will vary depending on the specifications and load of the truck. Some models are also equipped with additional auxiliary fuel tanks to increase the vehicle's range. When driving long distances, truck drivers will take a break on the way or load and unload goods after transporting them to the destination. Since there is a large amount of oil in the tank, people who break legal and moral constraints will be tempted by the oil in the tank, pry open the tank cap, and insert the oil pipe into it, which can quickly drain the entire tank of oil. If it is stolen while stopping for a rest or loading and unloading, it will not only cause heavy losses, but will also affect the subsequent journey. For this reason, an anti-theft device suitable for truck iron fuel tanks is designed.

DETAILED DESCRIPTION

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.

Example:

Please refer to Figures 1-6, an anti-theft device suitable for an iron fuel tank of a truck, including an iron fuel tank port 1 of the truck, a fuel tank cap 2 is threadedly connected to the iron fuel tank port 1 of the truck, a shielding cover 4 is detachably connected to the top of the iron fuel tank port 1 of the truck, an alarm 14 is embedded in the bottom of the shielding cover 4, a contact type concealed starting mechanism 1 adapted to the alarm 14 is provided at the bottom of the shielding cover 4 located just above the fuel tank cap 2, and a contact type concealed starting mechanism 2 adapted to the alarm 14 is provided at the connection between the shielding cover 4 and the iron fuel tank port 1 of the truck.

Specifically, a guide slot is provided at the bottom of the shielding cover 4, which is located just above the fuel tank cover 2. A contact-type concealed starting mechanism is arranged in the guide slot. The contact-type concealed starting mechanism includes a support plate 17 fixedly connected to the middle of the guide slot. A slide bar 18 with a lifting plate 16 fixedly connected to the bottom of the support plate 17 is slidably matched. A contact switch 20 adapted to the alarm 14 is fixedly installed above the slide bar 18, which is located at the top of the guide slot. A spring 3 19 is mounted on the slide bar 18. The top and bottom ends of the spring 3 19 are fixedly connected to the support plate 17 and the lifting plate 16, respectively. By setting the guide slot, the contact switch 20 adapted to the alarm 14 is fixedly installed above the slide bar 18, which is located at the top of the guide slot. The slide groove is convenient for hiding the contact-type concealed starting mechanism 1. When the fuel tank cover 2 is unscrewed from the top of the truck's iron fuel tank port 1, the fuel tank cover 2 moves up. When it needs to be moved out from the top of the truck's iron fuel tank port 1, the slide bar 18 must be moved up against the lifting plate 16, so that the spring three 19 is compressed, and the top of the slide bar 18 contacts the contact switch 1 20, and then the contact switch 1 20 transmits a signal to the alarm 14, triggering the alarm 14 to alarm. When the fuel tank cover 2 is removed from under the lifting plate 16, under the action of the rebound force of the spring three 19, the lifting plate 16 is moved down, so that the top of the slide bar 18 is out of contact with the contact switch 1 20.

Specifically, a fixing frame 3 fixedly connected to the iron fuel tank port 1 of the truck is arranged below the shielding cover 4, two clamping rods 5 are symmetrically fixedly connected to the top of the fixing frame 3, two slide rail grooves adapted to the clamping rods 5 are arranged at the bottom of the shielding cover 4, and a clamping mechanism adapted to the two clamping rods 5 is arranged on the shielding cover 4. An embedded groove 10 is extended inside the two slide rail grooves, and a slider 11 that can reciprocate toward the slide rail groove is slidably connected in the embedded groove 10. The slider 11 is fixedly connected to one end of the embedded groove 10 away from the slide rail groove by a spring 12, and the embedded groove 10 A contact switch 13 compatible with the alarm 14 is fixedly installed on the side away from the spring 12. When the contact clamping mechanism is clamped, the shielding cover 4 can be slid down from the two clamping rods 5. Under the action of the rebound force of the spring 12, the slider 11 can move toward the side of the slide rail groove, so that the slider 11 can release the contact switch 13, and then transmit the signal to the alarm 14, thereby causing the alarm 14 to sound an alarm. When the shielding cover 4 is pushed into the clamping rod 5, and the clamping rod 5 pushes the slider 11 inward, the contact between the contact switch 13 and the slider 11 can be released.

Specifically, the clamping mechanism includes a guide seat 6 symmetrically fixedly connected between the two slide rail grooves, the two guide seats 6 are slidably matched with guide rods 7, the two clamping rods 5 are provided with a clamping socket matched with the guide rod 7 on the side facing the guide seat 6, the two guide rods 7 are fixedly connected on the opposite side of the two guide rods 7, and a spring 9 is fixedly connected between the two slides 8. By pinching the two slides 8 toward the middle, the spring 9 can be compressed, so that the two guide rods 7 can be removed from the clamping sockets on the two clamping rods 5, and the shielding cover 4 can be removed from the fixed frame 3.

Specifically, rollers 22 are rotatably connected to both sides of the bottom of the shielding cover 4, and a through groove 15 that can slide with the fuel tank cover 2 is opened at the bottom of the shielding cover 4. The setting of the roller 22 can avoid bumps to the operator. The setting of the through groove 15 can facilitate the guidance of the fuel tank cover 2 to avoid being taken out from one side of the roller 22, thereby protecting the roller 22.

Specifically, a solar panel 21 is also provided on the top of the shielding cover 4. By providing the solar panel 21, it is convenient to absorb solar energy outdoors, and a solar energy conversion storage device is installed in the shielding cover 4 to convert the solar energy absorbed by the solar panel 21 into electrical energy and store it, and provide electrical energy for the alarm 14 to ensure that the alarm 14 can sound the alarm for a long time.

When in use, when an oil thief comes to steal oil, he can directly remove the tank cap 2, or he can first remove the shielding cover 4 and then unscrew the tank cap 2. If he directly unscrews the tank cap 2 from the iron tank port 1 of the truck, and then takes it out from between the iron tank port 1 of the truck and the shielding cover 4, the tank cap 2 will be pushed up to the contact-type concealed starting mechanism 1, thereby causing the alarm 14 to sound. If he intends to remove the shielding cover 4 first, during the disassembly process, the contact-type concealed starting mechanism 2 will be triggered to start, thereby causing the alarm 14 to sound. It has a double concealed alarm function and enhances the anti-theft performance.
