Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a car fuel tank fastening strap with the advantage of adjustable tightness, thus solving the aforementioned problems.

[0005] (II) Technical Solution

[0006] To achieve the above-mentioned purpose of adjusting tightness, this utility model provides the following technical solution: a car fuel tank fastening strap, including a bracket installed on a large truck, a fuel tank body installed on the top of the bracket, a strap fitting on the outside of the fuel tank body, and fastening components provided at both ends of the strap fitting, the fastening components being movably embedded in the reserved groove inside the bracket.

[0007] Preferably, the strap is composed of rubber and stainless steel sheet, with the rubber sheet fitted over the outside of the stainless steel sheet, and the strap is fitted into a pre-reserved groove on the outer wall of the fuel tank.

[0008] Preferably, the fastening assembly includes a housing, which is detachably installed with a bracket by bolts. A slide block is slidably installed on the inner wall of the housing via a slide table. A threaded sleeve is movably installed inside the slide block. An adjusting screw is threadedly connected inside the threaded sleeve. Both ends of the adjusting screw extend to the outside of the housing, and a cross groove adapted to the tool is provided at the bottom of the adjusting screw.

[0009] Preferably, a U-shaped frame is rotatably mounted on the top of the adjusting screw, and collars are fixedly mounted on both ends of the U-shaped frame. A shaft is inserted inside the collar, and limit plates are fixedly mounted on both ends of the shaft. Two symmetrically arranged washers are fitted on the outer side of the shaft.

[0010] Preferably, a bushing is movably fitted on the outer side of the shaft and between the two washers, and a connecting plate is fixedly installed on the top of the bushing. The top of the connecting plate is fixedly installed to the tail end of the stainless steel sheet.

[0011] Preferably, a locking nut is threaded to one end of the adjusting screw that extends to the housing, and the diameter of the locking nut is larger than the diameter of the slide block.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a car fuel tank fastening strap, which has the following beneficial effects:

[0014] 1. In this application, the adjusting screw and the U-shaped bracket are movably connected. Therefore, the U-shaped bracket, the shaft, and the strap will not rotate with the adjusting screw. The adjusting screw is driven by a tool to rotate and move downward in the threaded sleeve, which in turn pulls the U-shaped bracket, the shaft, and the connecting plate downward. At the same time, the adjusting screws in the fastening components on both sides are driven synchronously, thus ensuring that the entire strap begins to move downward and securely fasten the fuel tank. Conversely, adjusting the screw will cause the strap to loosen.

[0015] 2. After the car fuel tank fastening strap is tightened, a locking nut is threaded onto the bottom of the adjusting screw to further enhance the connection's firmness. Simultaneously, if the vertical strap of the strap is found to be not in contact with the outer wall of the fuel tank, a tool is used to drive the slide block within the housing (the slide block cannot be moved without external force), thereby bringing the vertical strap of the strap into contact with the outer wall of the fuel tank. This ensures that the vertical strap of the strap is in a vertical position, preventing it from tilting arbitrarily and causing insecure fastening. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-2 A car fuel tank fastening strap includes a bracket 1 installed on a large truck, a fuel tank body 2 installed on the top of the bracket 1, a strap 3 fitted on the outside of the fuel tank body 2, and fastening components 4 provided at both ends of the strap 3. The fastening components 4 are movably embedded in the reserved groove inside the bracket 1.

[0024] Please see Figure 1-2 The strap 3 is composed of rubber and stainless steel sheet. The rubber sheet is fitted on the outside of the stainless steel sheet, preventing the stainless steel sheet from contacting the fuel tank body 2. The strap 3 is fitted into the reserved groove on the outer wall of the fuel tank body 2. After being tightened, the strap 3 and the fuel tank body 2 restrict each other, which strengthens the connection.

[0025] Please see Figure 3-5 The fastening assembly 4 includes a housing 41, which is detachably installed to the bracket 1 by bolts 42. A slide block 44 is slidably installed on the inner wall of the housing 41 via a slide table 43. A threaded sleeve 45 is movably installed inside the slide block 44. An adjusting screw 46 is threadedly connected inside the threaded sleeve 45. Both ends of the adjusting screw 46 extend to the outside of the housing 41, and a cross groove adapted to the tool is provided at the bottom of the adjusting screw 46.

[0026] Please see Figure 3-5 A U-shaped frame 47 is rotatably mounted on the top of the adjusting screw 46. A collar 48 is fixedly mounted on both ends of the U-shaped frame 47. A shaft 49 is inserted inside the collar 48. Limiting plates are fixedly mounted on both ends of the shaft 49. Two symmetrically arranged washers 410 are fitted on the outer side of the shaft 49.

[0027] Please see Figure 3-5 A bushing 411 is movably fitted on the outside of the shaft 49 and between two washers 410. A connecting plate 412 is fixedly installed on the top of the bushing 411, and the top of the connecting plate 412 is fixedly installed to the tail end of the stainless steel sheet.

[0028] Please see Figure 3-5The bottom of the adjusting screw 46 extends to one end of the housing 41 and is threaded with a locking nut 413. The diameter of the locking nut 413 is larger than the diameter of the slide block 44. The diameter of the locking nut 413 can also be larger than the diameter of the housing 41. After the adjusting screw 46 drives the strap 3 to securely bind the oil tank 2, the locking nut 413 is threaded onto the bottom of the adjusting screw 46, which further strengthens the connection of the adjusting screw 46.

[0029] Working principle: In use, the adjusting screw 46 and the U-shaped frame 47 are movably connected, so the U-shaped frame 47, the shaft 49 and the strap 3 will not rotate with the adjusting screw 46. The adjusting screw 46 is driven by a tool to rotate and move downward in the threaded sleeve 45, which in turn pulls the U-shaped frame 47, the shaft 49 and the connecting plate 412 downward. At the same time, the adjusting screws 46 in the fastening components 4 on both sides are driven synchronously, thus ensuring that the entire strap 3 begins to move downward and securely fasten the oil tank body 2. Conversely, adjusting the screw 46 will loosen the strap 3.

[0030] After the strap 3 is tightened, a locking nut 413 is threaded onto the bottom of the adjusting screw 46 to further strengthen the connection. At the same time, if it is found that the vertical strap of the strap 3 is not in contact with the outer wall of the tank body 2, the slide 44 is driven to slide in the housing 41 by a tool (the slide 44 cannot be driven to move without external force), so that the vertical strap of the strap 3 is in contact with the outer wall of the tank body 2. In this way, the vertical strap of the strap 3 will also form a vertical state with the support 1, ensuring that the vertical strap of the strap 3 will not tilt arbitrarily and cause the defect of loose binding.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
