[0001] The utility model relates to a wear-resistant fuel truck ground well joint roller bracket, in particular to a wear-resistant fuel truck ground well joint roller bracket applied to the field of roller brackets. Background Art

[0002] A pipeline fuel truck is a device specially used for refueling aircraft. Its main function is to quickly and safely input aviation fuel into the aircraft. The ground well joint of the pipeline fuel truck is equipped with a roller bracket (imported product), which has the function of quickly retracting and extending the ground well joint.

[0003] The locking on the existing fuel truck roller bracket is made of alloy material with a thickness of 3 millimeters. Its own strength is insufficient, and it is deformed or broken under long-term working stress. Because it is an imported product, the procurement cycle of accessories is long and the price is expensive, which brings great hidden dangers to the normal fuel supply of the pipeline truck. In addition, the installation and disassembly steps of the locking piece on it are cumbersome, and a variety of disassembly and assembly tools are required during disassembly and assembly. Summary of the Invention

[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that the locking piece on the existing fuel truck roller bracket not only has cumbersome and inconvenient installation and disassembly steps, but also is prone to deformation or fracture under long-term working stress.

A shock-absorbing spring is sleeved on the outer end of the fixed rod and the shock-absorbing spring is located inside the fixed bracket. A bolt one is threadedly connected to the inside of the fixed rod, and one end of the bolt one extends out of the socket frame. One end of the fixed bracket away from the sleeve plate is fixedly connected with a pair of rollers through a bolt two. A pair of rectangular grooves are opened at the upper end of the fixed bracket, a docking groove communicating with the plugging hole is opened inside the rectangular groove, a reinforcing rod is movably inserted into the docking groove, a compression spring one is sleeved on the outer end of the reinforcing rod, a limiting ring is fixedly connected to the end of the compression spring one away from the fixed bracket, a pair of limiting grooves are opened on the inner wall surfaces of the pair of rectangular grooves, a plugging pipe is movably inserted into the limiting grooves, and a pair of outer end grooves for movably inserting the plugging pipe are opened on the outer end of the limiting ring.

[0006] In the above-mentioned wear-resistant fuel truck ground well joint roller bracket, its bearing capacity and endurance are relatively ideal, not easy to deform and break. At the same time, its installation and disassembly steps are simple, and no disassembly and assembly tools are required during disassembly and assembly.

[0007] As a further improvement of the present application, the insertion hole communicates with the fixed groove, and the insertion rod penetrates and is inserted inside the locking piece.

[0008] As a further improvement of the present application, a return spring is fixedly connected inside the fixed groove, and the upper end of the return spring is fixedly connected to the lower end of the locking piece.

[0010] As a further improvement of the present application, one end of the insertion pipe far from the limiting ring is fixedly connected to a compression spring II, and one end of the compression spring II is fixedly connected to the inner wall of the limiting groove.

[0011] As a further improvement of the present application, gaskets are placed in a fitting manner between the locking piece and the fixed groove, between the fixed frame and the sleeve plate, and between the sleeve plate and the socket frame.

[0012] As another improvement of the present application, a pair of protective grooves are opened at the upper end of the fixed frame. An insertion frame is movably inserted inside the protective grooves. One end of the insertion frame far from the fixed frame is fixedly connected to a protective cover. A magnetic coating I is applied to the outer end of the insertion frame, a magnetic coating II is applied to the inner wall of the protective grooves, and a pair of moving pipes are fixedly connected to the inner wall of the protective cover.

[0022] The following will describe in detail two embodiments of the present application with reference to the accompanying drawings.

[0023] The first embodiment:

[0024] Figures 1-4 With Figure 6 There is shown a wear-resistant fuel truck ground well joint roller bracket, including a fixed frame 1. A fixed groove 2 is opened at the upper end of the fixed frame 1. A locking piece 3 is movably inserted inside the fixed groove 2. An insertion hole 4 is opened on the fixed frame 1. An insertion rod 5 is movably inserted inside the insertion hole 4. A sleeve plate 6 is sleeved on the outer side of one end of the fixed frame 1. A socket frame 7 is sleeved on the outer end of the sleeve plate 6. A pair of round holes 8 are opened on the fixed frame 1, the sleeve plate 6 and the socket frame 7. The fixed frame 1, the sleeve plate 6 and the socket frame 7 are connected to the same fixed rod 9. And both ends of the fixed rod 9 are respectively inserted inside the round holes 8 of the above three. A shock-absorbing spring 10 is sleeved on the outer end of the fixed rod 9 and the shock-absorbing spring 10 is located inside the fixed frame 1. A bolt 11 is threadedly connected inside the fixed rod 9. Insert the outer end of the fixed frame 1 into the sleeve plate 6 so that the inner wall of the sleeve plate 6 fits with the outer end of the fixed frame 1. Then place the fixed frame 1 and the sleeve plate 6 in the socket frame 7. At the same time, the outer end of the sleeve plate 6 fits with the inner wall of the socket frame 7. Then insert the fixed rod 9 through the fixed frame 1, the sleeve plate 6 and the socket frame 7. Finally, fix the fixed rod 9 with the bolt 11, thereby installing the fixed frame 1, the sleeve plate 6 and the socket frame 7 together. One end of the bolt 11 extends out from inside the socket frame 7. A pair of rollers 12 are fixedly connected to the end of the fixed frame 1 away from the sleeve plate 6 through a bolt 2;

[0025] A pair of rectangular grooves 13 are formed at the upper end of the fixed frame 1. A docking groove 14 communicating with the insertion hole 4 is formed inside the rectangular groove 13. A reinforcing rod 15 is movably inserted inside the docking groove 14. A first compression spring 16 is sleeved on the outer end of the reinforcing rod 15. One end of the first compression spring 16 away from the fixed frame 1 is fixedly connected with a limit ring 17. Limit grooves 18 are formed on the inner wall surfaces of the pair of rectangular grooves 13. An insertion pipe 19 is movably inserted inside the limit groove 18. A pair of outer end grooves 20 for movably inserting the insertion pipe 19 are formed at the outer end of the limit ring 17.

[0026] The insertion hole 4 communicates with the fixed groove 2. The insertion rod 5 is inserted through the inside of the locking piece 3. A return spring 30 is fixedly connected inside the fixed groove 2. By using the return spring 30, it is convenient for the locking piece 3 to return after moving. The upper end of the return spring 30 is fixedly connected with the lower end of the locking piece 3. One end of the first compression spring 16 close to the fixed frame 1 is movably connected with the inner wall of the rectangular groove 13. The inner wall of the limit ring 17 is fixedly connected with the outer end of the reinforcing rod 15. A second compression spring 21 is fixedly connected to the end of the insertion pipe 19 away from the limit ring 17. One end of the second compression spring 21 is fixedly connected with the inner wall of the limit groove 18. Gaskets 22 are placed between the locking piece 3 and the fixed groove 2, between the fixed frame 1 and the sleeve plate 6, and between the sleeve plate 6 and the socket frame 7. By using the gaskets 22, the stability of the locking piece 3 inside the fixed groove 2, between the fixed frame 1 and the sleeve plate 6, and between the sleeve plate 6 and the socket frame 7 can be improved.

[0027] The locking piece 3 is made of 304 stainless steel, which can increase its compressive strength. At the same time, the thickness and width of the locking piece 3 are increased (as Figure 6 shown, the width at h in the figure is the width before the structural improvement, and the width at H in the figure is the width after the structural improvement). After measurement, the gap at the locking installation position is six millimeters. The locking thickness is remade to be 5.7 millimeters, and the easily breakable part of the locking piece 3 is widened. In this way, the bearing capacity and tolerance of the locking piece 3 can be greatly improved, so that the locking piece 3 is not easily deformed and broken.

[0028] When installing the locking piece 3, the reinforcing rod 15 and the first compression spring 16 need to be placed inside the rectangular groove 13. Then move the reinforcing rod 15 so that one end of it moves towards the docking groove 14 and penetrates the docking groove 14 and inserts into the insertion rod 5, thereby fixing the insertion rod 5 and the locking piece 3. At the same time, the limit ring 17 will squeeze the first compression spring 16, causing the first compression spring 16 to contract between the limit ring 17 and the rectangular groove 13. Then under the elastic force of the second compression spring 21, it will push the insertion pipe 19 so that one end of it inserts into the outer end groove 20, thereby limiting the limit ring 17 and the reinforcing rod 15 and improving their stability inside the rectangular groove 13.

[0029] In summary, when the bracket is in use, it not only has relatively ideal bearing capacity and tolerance, is not easily deformed and broken, but also has simple disassembly and assembly steps and does not require disassembly and assembly tools during disassembly and assembly.

[0030] The second implementation mode:

[0031] On the basis of the first implementation mode, this implementation mode adds structures such as the insertion rack 24 and the protective cover 25, and the rest is the same as the first implementation mode.

[0032] Figure 2 With Figure 5 It is shown that a pair of protective grooves 23 are opened at the upper end of the fixed frame 1. The insertion rack 24 is movably inserted into the protective grooves 23. One end of the insertion rack 24 away from the fixed frame 1 is fixedly connected with the protective cover 25. A first magnetic coating 26 is coated on the outer end of the insertion rack 24, and a second magnetic coating 27 is coated on the inner wall of the protective grooves 23. A pair of moving pipes 28 are fixedly connected to the inner wall of the protective cover 25. A reinforcing groove 29 for movably inserting the moving pipes 28 is opened at the outer end of the insertion pipe 19.

[0033] After the locking piece 3 is installed, the insertion rack 24 is inserted into the protective grooves 23, so that the first magnetic coating 26 and the second magnetic coating 27 are adsorbed together, thereby fixing the insertion rack 24 in the protective grooves 23, and further fixing the protective cover 25 on the fixed frame 1. The protective cover 25 can not only protect the insertion pipe 19, the limiting ring 17, and the insertion rod 5, but also prevent dust and foreign objects from easily entering the rectangular groove 13.

[0034] Combined with the current actual requirements, the above implementation mode adopted by this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
