Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories installation, and more specifically, particularly relates to a fixing tool for an automobile fuel tank. Background Art

[0002] A fuel tank is an independent box container device fixed on a car and used to store fuel, usually used on machines driven by gasoline or diesel engines. At present, fuel tanks are usually fixed on cars by using a tank bracket and a fixing tie. However, the tank bracket is mostly welded or bolted to form a fixed frame structure. Different sizes of tanks need to be customized with tank brackets for fixed bearing. It can be seen that the structure of the traditional tank bracket has poor versatility and cannot be uniformly installed for different types of tanks. In addition, the tank bracket is usually rigidly connected to the chassis of the vehicle body. When the vehicle body is bumped and vibrated, it is very easy to cause the tank bracket and the fuel tank to vibrate, which will destroy the stability of the fuel tank fixed on the tank bracket.

[0024] like Figure 1-Figure 8As shown, the utility model provides a vehicle fuel tank fixing tool, including a fuel tank 1 and a movable support frame 3; the fuel tank 1 is placed on the upper side of the movable support frame 11; it also includes a vehicle body fixing frame 4, a side plate 7 and a fixed support frame 19; the upper side of the movable support frame 3 is welded and connected to the support frame 11, the side of the support frame 11 is welded and connected to the sleeve 15, and the inner side of the sleeve 15 is slidably connected to the guide rod 16; the rear side of the fixed support frame 19 is welded and connected to the shock absorbing frame 6, the upper side and the lower side of the shock absorbing frame 6 are both bonded with rubber vibration isolation pads 5, the upper side of the fixed support frame 19 is welded and connected to the support frame 11, and the support frame 11 is welded and connected to the lower side of the support frame 11. A telescopic rod 10 is slidably connected inside the frame 11, a cable tie 2 is tied to the front end of the telescopic rod 10, a sliding block 13 is tied to the rear end of the cable tie 2, the sliding block 13 is meshed and connected to the outer side of the threaded rod 17, and a knob 12 is installed on the top of the threaded rod 17; a displacement plate 14 is welded and connected to the outer side of the sleeve 15, a two-way threaded adjustment rod 18 is meshed and connected to the displacement plate 14, and an adjustment knob 20 is installed on the left end of the two-way threaded adjustment rod 18; the supporting frame 11 is welded and connected to the side plate 7, and a clamping bolt 9 is screwed on the lower side of the supporting frame 11; the vehicle body fixing frame 4 is welded and connected to the top and bottom ends of the guide support rod 8.

[0025] When the utility model is performing the fixed installation work of the fuel tank, the adjusting knob 20 is first turned according to the length of the fuel tank 1, and the adjusting knob 20 drives the two-way threaded adjusting rod 18 to rotate. Since the positive thread end and the reverse thread end of the outer side surface of the two-way threaded adjusting rod 18 are respectively engaged and connected in the threaded through holes of the two groups of displacement plates 14, the two-way threaded adjusting rod 18 drives the two groups of displacement plates 14 to move left and right oppositely, and the two groups of displacement plates 14 pull the supporting frame 11 welded and connected by the sleeve 15 to move left and right oppositely, completing the adjustment work of the supporting frame 11 on the placement length position of the fuel tank 1, and then according to the width of the fuel tank 1, manually turn the clamping bolt 9 to loosen the telescopic rod 10 and the supporting frame 11, pull the telescopic rod 10 out of the front end opening position of the supporting frame 11, let the telescopic rod 10 slide to a suitable position according to the width of the fuel tank 1, and then turn the clamping bolt 9 in the opposite direction.

[0027] In the embodiment of the present disclosure, there are three groups of supporting frames 11, and the supporting frames 11 are arranged equidistantly from left to right. Each group of supporting frames 11 is an L-shaped structure with a hollow interior. The left and right sides of the supporting frames 11 are provided with through-groove structures, and the sliding blocks 13 are inserted in the through-groove structures of the supporting frames 11. The top and bottom of the L-shaped structure of the supporting frames 11 are provided with through-hole structures opposite to each other up and down. The upper and lower ends of the threaded rod 17 are rotatably connected in the through-holes of the supporting frames 11. The front end of the L-shaped structure of the supporting frames 11 is provided with an opening, and the telescopic rod 10 is inserted into the interior of the supporting frames 11 through the opening. The telescopic rod 10 is slidably connected to the supporting frames 11.
