In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0036] The utility model provides a kind of loader, and the loader includes main body, and main body has operating port. Specifically, operating port is equipped with engine and the component needing heat dissipation such as part. The loader further includes a fan assembly. Refer to Figures 2 to 3As shown, the fan assembly comprises a fixed frame 1, a movable frame 2, a fan body 3, a limiting support rod 4 and a limiting seat 5. The fan assembly comprises the fixed frame 1, the movable frame 2 and the fan body 3, the fan body 3 is arranged on the movable frame 2, the movable frame 2 is hingedly arranged on the fixed frame 1, and the movable frame 2 has an open position and a closed position. The fan assembly further comprises the limiting support rod 4 and the limiting seat 5, the limiting support rod 4 comprises a connecting segment 41 and a locking segment 42, the first end of the connecting segment 41 extends away from the hinged position of the movable frame 2 and the fixed frame 1, the first end of the connecting segment 41 is hingedly connected to the movable frame 2, and the locking segment 42 is arranged at the second end of the connecting segment 41 and is arranged at an angle with the connecting segment 41. The limiting seat 5 is fixedly arranged on the fixed frame 1 and located below the limiting support rod 4, the limiting seat 5 is provided with a limiting lock hole 521, and the locking segment 42 can be inserted into the limiting lock hole 521 when the movable frame 2 is in the open position. In this embodiment, the fan assembly is located in the main body, and the movable frame 2 moves towards the operating port during the process of swinging from the closed position to the open position.

[0037] In this embodiment, the fan assembly comprises the limiting support rod 4 and the limiting seat 5, the limiting support rod 4 can swing relative to the movable frame 2, the limiting seat 5 is fixedly arranged on the fixed frame 1 and is provided with the limiting lock hole 521 corresponding to the locking segment 42 of the limiting support rod 4. During the process of gradually opening the fan assembly, the movable frame 2 swings from the closed position to the open position, when the movable frame 2 swings to the target position, i.e. the open position, the locking segment 42 of the limiting support rod 4 can be inserted into the limiting lock hole 521 to lock the movable frame 2, thereby achieving effective positioning of the movable frame 2, which is simple in structure and convenient to operate. When the fan assembly is applied to the loader, the connecting segment 41 extending away from the hinged position of the movable frame 2 and the fixed frame 1 is closer to the operating port when the movable frame 2 is in the open position, so that when the limiting support rod 4 needs to be unlocked, the maintenance personnel do not need to climb onto the counterweight assembly of the loader, but only need to hold the movable frame 2 with one hand and lift the connecting segment 41 with the other hand, so that the locking segment 42 can be pulled out of the limiting lock hole 521, thereby achieving the unlocking work, which makes the operation of the maintenance personnel more convenient and reliable and reduces the labor intensity.

[0038] In addition, due to the traditional structure using a latch for limiting, the latch is vertically inserted, which occupies a certain longitudinal space inside the loader. In this embodiment, the connecting segment 41 extends away from the hinged position of the movable frame 2 and the fixed frame 1, which is equivalent to that the limiting support rod 4 is arranged in a direction tending to be horizontal, thereby reducing the occupation of the longitudinal space inside the loader to a certain extent.

[0039] In the embodiment, the first end of the connecting section 41 is hingedly connected with the movable frame 2 through a hinge shaft (not shown) which is arranged perpendicularly to the axis of the limiting lock hole 521. The locking section 42 slides on the limiting seat 5 during the process that the movable frame 2 swings from the closed position to the open position. In this way, the swinging direction of the limiting support rod 4 as a whole is limited. During the process that the movable frame 2 swings from the closed position to the open position, the connecting section 41 of the limiting support rod 4 swings relative to the movable frame 2, and the locking section 42 of the limiting support rod 4 slides on the limiting seat 5. When the movable frame 2 swings to the target position, i.e., the open position, the locking section 42 of the limiting support rod 4 slides to the position opposite to the limiting lock hole 521 and swings downward under the action of gravity and is automatically inserted into the limiting lock hole 521 to lock the movable frame 2, thereby achieving effective positioning of the movable frame 2. The above process does not need the operator to manually control the swinging direction of the limiting support rod 4, and thus the locking section 42 can be automatically inserted into the limiting lock hole 521, which improves the automation degree of the locking and limiting process and reduces the labor intensity of the operator.

[0040] It can be understood that, in some alternative embodiments, the first end of the connecting section 41 and the movable frame 2 can also be connected through a ball hinge structure similar to a universal joint. In this case, the operator needs to manually control the swinging direction of the connecting section 41 so that the hinge shaft of the connecting section 41 is arranged perpendicularly to the axis of the limiting lock hole 521.

[0041] In the embodiment, the locking section 42 is arranged to extend in the direction close to the limiting seat 5 relative to the connecting section 41. Alternatively, a sliding groove (not shown) which is communicated with the limiting lock hole 521 can be formed on the limiting seat 5 corresponding to the sliding track of the locking section 42 on the limiting seat 5, so that the end of the locking section 42 can slide in the sliding groove. In this way, the sliding track of the locking section 42 can be further specified.

[0042] Specifically, the connecting section 41 and the locking section 42 are arranged at an angle of 90°. Specifically, when the connecting section 41 extends in the horizontal direction, the locking section 42 extends downward in the vertical direction.

[0043] In the embodiment, the limiting seat 5 comprises a guiding portion 51 and a locking portion 52. The guiding portion 51 is upwardly inclined from the first end to the second end. The locking portion 52 is connected to the second end of the guiding portion 51. The limiting lock hole 521 is formed on the locking portion 52. The locking segment 42 is adapted to slide from the guiding portion 51 to the locking portion 52 during the process that the movable frame 2 swings from the closed position to the open position. Specifically, during the process that the movable frame 2 swings from the closed position to the open position, the limiting support rod 4 has a tendency to swing upward as a whole, and specifically, one end of the locking segment 42 gradually rises during the process that the one end of the locking segment 42 is in sliding contact with the guiding portion 51. In this way, when the movable frame 2 swings to the open position and the locking segment 42 slides to align with the limiting lock hole 521, the upwardly swinging locking segment 42 can more effectively fall under the action of gravity, thereby being effectively inserted into the limiting lock hole 521.

[0044] Specifically, the connecting segment 41 and the locking segment 42 are connected with a rounded segment 43. The rounded segment 43 is arranged to smoothly bend and transition between the connecting segment 41 and the locking segment 42, effectively ensuring the overall strength of the limiting support rod 4 and avoiding stress concentration of the limiting support rod 4.

[0045] Optionally, the connecting segment 41, the rounded segment 43 and the locking segment 42 are integrally formed. In this way, the overall structure of the limiting support rod 4 is simple and convenient to process and reliable.

[0046] In the embodiment, the movable frame 2 is provided with a first fixed head 61. The first end of the connecting segment 41 is hingedly arranged on the first fixed head 61. By arranging the first fixed head 61, a reliable connecting space is provided for the connecting segment 41 of the limiting support rod 4. Specifically, the first fixed head 61 is provided with a hinge shaft. The first end of the limiting support rod 4, i.e. the first end of the connecting segment 41, is hingedly connected to the first fixed head 61 through the hinge shaft.

[0047] In the embodiment, the movable frame 2 is provided with a second fixed head 62. The second fixed head 62 is provided with a guiding groove 621. The groove opening of the guiding groove 621 faces the limiting support rod 4. The end of the guiding groove 621 away from the groove opening extends toward the side where the limiting lock hole 521 is located. The locking segment 42 can slide in the guiding groove 621 above the limiting lock hole 521 and fall into the limiting lock hole 521 under its own gravity. Specifically, by arranging the second fixed head 62, a reliable directional restriction is provided for the swinging space of the limiting support rod 4. Specifically, the locking segment 42 and the guiding groove 621 slide to guide the trajectory of the locking segment 42, so that the locking segment 42 is smoothly aligned and inserted into the limiting lock hole 521. The width of the guiding groove 621 is slightly larger than the diameter of the second end of the limiting support rod 4, i.e. the locking segment 42, to ensure smooth and flexible sliding of the locking segment 42.

[0048] In the embodiment, the first fixing head 61 and / or the second fixing head 62 is fixedly connected with the movable frame 2 by a screw. The screw connection is reliable and stable, and the first fixing head 61 and the second fixing head 62 are convenient to replace.

[0049] The embodiment is not limited thereto, and the first fixing head 61 and / or the second fixing head 62 can also be fixedly connected with the movable frame 2 by welding or the like.

[0050] In the embodiment, the limiting seat 5 is fixedly connected with the fixing frame 1 by a screw. The screw connection is reliable and stable, and the limiting seat 5 is convenient to replace. The embodiment is not limited thereto, and the limiting seat 5 can also be fixedly connected with the fixing frame 1 by welding or the like.

[0051] In summary, the fan assembly provided by the embodiment reduces the space occupation, and can be more suitable for being arranged in the loader. The movable frame 2 is automatically locked after being opened, and the operation of the maintenance personnel is simplified. The limiting support rod 4 and the limiting seat 5 can be relatively arranged outward, so that the maintenance personnel does not need to climb on the counterweight assembly of the loader, and the labor intensity of the maintenance personnel is reduced.

[0052] Obviously, the above embodiment of the utility model is only for clearly illustrating the utility model, and is not a limitation on the implementation manner of the utility model. For ordinary skilled in the art, various obvious changes, re-adjustment and replacement can be made without departing from the protection scope of the utility model. Here, all the implementation manners are not required or can not be exhausted. Any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model claim.
