[0002] A reach truck, also known as a reach truck, is an industrial handling vehicle used for loading, unloading, stacking and short-distance transportation of palletized goods.

[0003] Oil supply and return pipes are generally installed between the slide and the frame of a forward-moving storage vehicle. When the door frame moves forward, the oil supply and return pipes will rub against the slide or the frame. Therefore, a protective sleeve similar to a tank chain is currently assembled on the oil supply and return pipes to prevent wear of the oil supply and return pipes. However, this type of arrangement structure is costly, complex in structure and inconvenient to assemble. Utility Model Content

[0019] Figure 2 Shown Figure 1 Enlarged schematic diagram of area A in the middle. DETAILED DESCRIPTION

[0020] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0021] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0022] Example 1

[0023] Reference Figure 1 and Figure 2 As shown, the first embodiment provides a layout structure of a forklift oil pipe (hereinafter referred to as the layout structure) for arranging the oil inlet and return pipes between the slide and the frame of the forklift, and the oil inlet and return pipes are referred to as oil pipes 1.

[0024] The arrangement structure of this embodiment includes an oil pipe 1 and a first support frame 4 and a second support frame 5 that move relative to each other. The two sides of the oil pipe 1 are fixed to the first support frame 4 and the second support frame 5 by two fixing parts 2 respectively and form a first fixed end and a second fixed end respectively. The oil pipe located between the first fixed end and the second fixed end is a bendable bending portion 11. Specifically, the first support frame 4 and the second support frame 5 are the slide and frame of the forklift respectively, and move relative to each other when the mast of the forklift moves forward, and the bending portion 11 of the synchronous oil pipe 1 can follow the relative movement between the first support frame 4 and the second support frame 5.

[0025] The arrangement structure of this embodiment further includes a spiral sheath 3 for protecting the oil pipe 1. The spiral sheath 3 has a spiral coil and is spirally wound around the outer circumference of the bend 11, so that the bend 11 and the spiral sheath 3 form a synchronous telescopic arrangement.

[0026] More specifically, the fixing members 2 are pipe clamps located at both ends of the bend 11. The two fixing members 2 respectively embrace the two sides of the oil pipe 1 and are fixed to the first support frame 4 and the second support frame 5, ensuring that two fixed support points are formed at each end of the bend 11 to limit the installation position of the oil pipe 1 on the first support frame 4 and the second support frame 5. The two fixed support points at this time correspond to the first fixed end and the second fixed end, respectively. Of course, in other embodiments, the fixing members 2 can also be cable ties, etc.

[0027] During specific implementation, the specific spiral sheath 3 is a low-cost spring sheath, such as a metal sheath made of steel or copper with a spring structure, or a plastic sheath made of nylon or polypropylene with a spring structure, and the spiral sheath 3 is inserted into the position of the bent portion 11 in the middle of the oil pipe 1, and one end of the bent portion 11 is fixed to the first support frame 4 through one of the fixing members 2, and the other end is fixed to the second support frame 5 through another fixing member 2 to complete the entire assembly. Therefore, the arrangement structure of this embodiment is simple, compact and easy to assemble.

[0028] In addition, the oil pipe has a first connecting portion and a second connecting portion respectively connected to both ends of the bending portion 11 , and the outward oil passage interfaces of the first connecting portion and the second connecting portion are respectively connected to the oil passages on the first support frame 4 and the second support frame 5 .

[0029] When the mast of the forklift moves forward, the oil pipe 1 and the spiral sheath 3 form a whole and have elastic expansion and contraction similar to a spring. Then, because the spiral sheath 3 is located between the first support frame 4 and the second support frame 5, and the bent portion 11 is wrapped by the spiral sheath 3, the friction between the oil pipe 1 and the first support frame 4 is isolated, thereby protecting the oil pipe 1.

[0030] By spirally winding the spiral coil of the spiral sheath 3 around the outer circumference of the bent portion 11 of the oil pipe 1, it is ensured that the bent portion 11 of the oil pipe 1 and the spiral sheath 3 together form a synchronously telescopic whole, and the spiral sheath 3 effectively isolates the direct contact and friction between the bent portion 11 of the oil pipe 1 and the supporting components of the forklift (such as the first support frame 4 and the second support frame 5) to prevent the oil pipe 1 from wear. At the same time, the layout structure of this embodiment is simple, compact and low-cost, and it is only necessary to put the spiral sheath 3 on the oil pipe 1, which is also convenient for installation.

[0031] Of course, in other embodiments, the spiral sheath 3 may also be a flexible sheath, such as a plastic sheath made of nylon or polypropylene.

[0032] Example 2

[0034] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
