[0031] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0032] As described in the background technology, the deposited debris in the radiator interlayer is inconvenient to clean, which reduces the effective air volume and affects the heat dissipation performance, thus often leading to high temperature failure of the radiator. In order to solve the above technical problems, the utility model proposes a series radiator structure that can be easily cleaned during daily maintenance.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment of the utility model, a loader radiator structure is proposed, including: a water radiator 1 and an oil radiator 2; Figure 4 , Figure 5 As shown, the left end of the water radiator 1 is provided with a fixing block 12, and the right end of the water radiator 1 is provided with a locking shaft 16, a guide groove 15 and a buffer column 14; Figure 4 , Figure 6 As shown, the oil radiator 2 is located on one side of the water radiator 1, and a rotating shaft block 22 is provided at the left end of the oil radiator 2. The rotating shaft block 22 is inserted into the fixed block 12 and rotatably connected. A lock buckle 24, a guide block 26 and a limit baffle 25 are provided at the right end of the oil radiator 2. In the closed state, the lock buckle 24 is locked with the lock shaft 16, the guide block 26 is inserted into the guide groove 15, and the limit baffle 25 abuts against the buffer column 14.

[0034] Among them, the lock buckle 24 and the lock shaft 16 are finished kits, which are purchased on the market. The purchaser will install the lock buckle 24 and the lock shaft 16 on the oil radiator 2 and the water radiator 1 respectively, and use them to lock when closing the oil radiator 2.

[0035] In the radiator structure of this embodiment, by setting a rotating shaft block 22 at the left end of the oil radiator 2 and a fixing block 12 at the left end of the water radiator 1, the rotating shaft block 22 is rotatably connected with the fixing block 12, and the oil radiator 2 can be opened at an angle range (a) ≤ 90°. When it is necessary to clean the debris in the radiator interlayer, it is only necessary to manually press the lock buckle 24 downward to open and rotate the oil radiator 2 to any angle within 90°, without the assistance of special tools, and only one person can operate it, which can more conveniently clean various surfaces within the opening angle, avoid debris affecting the heat dissipation performance, and reduce high temperature failures of the radiator.

[0036] Due to the relatively low machining accuracy in the engineering field and the fact that the fixing of the rotating shaft block 22 and the fixing block 12 usually adopts a welding method, resulting in insufficient accuracy in terms of position, angle, etc. In addition, the oil radiator 2 has a certain weight, and during long-term use, there will inevitably be a certain degree of sagging. Due to the above reasons, it is easy to cause the problem that the lock catch 24 and the lock shaft 16 cannot be aligned. Based on this, in this embodiment, a guiding block 26 is provided at the right end of the oil radiator 2, and a guiding groove 15 is provided at the right end of the water radiator 1. Through the guiding action of the guiding block 26 and the guiding groove 15, the smooth locking of the lock catch 24 and the lock shaft 16 can be ensured.

[0037] When the oil radiator 2 closes and contacts the water radiator 1, it is easy to generate collisions, thereby causing damage to the radiator. Based on this, in this embodiment, a limiting baffle 25 is provided at the right end of the oil radiator 2, and a buffer post 14 is provided at the right end of the water radiator 1. Through the cooperation of the limiting baffle 25 and the buffer post 14, a limiting and buffering effect is provided to avoid damage to the radiator.

[0038] As Figure 4 shown, a left frame 11 is installed at the left end of the water radiator 1, and a right frame 13 is installed at the right end. The fixing block 12 is installed on the left frame 11, and the lock shaft 16, the guiding groove 15 and the buffer post 14 are installed on the right frame 13; a left support frame 21 is installed at the left end of the oil radiator 2, and a right support frame 23 is installed at the right end. Both the left support frame 21 and the right support frame 23 are bending plates integrally shaped like a "匚", and the left support frame 21 and the right support are inserted into the left and right ends of the oil radiator body and are connected and fixed by screws. The rotating shaft block 22 is installed on the left support frame 21, and the lock catch 24, the guiding block 26 and the limiting baffle 25 are provided on the right support frame 23. Through the left frame 11, the right frame 13, the left support frame 21 and the right support frame 23, it is convenient to transform the existing radiator.

[0039] As Figure 4 shown, every two of the fixing blocks 12 form a group, there is a set gap between the two fixing blocks 12, and the two fixing blocks 12 and the left frame 11 form a fork ear structure. The rotating shaft block 22 is an ear plate, and the ear plate is inserted into the gap between the two fixing blocks 12. As Figure 5 shown, the fixing block 12 and the rotating shaft block 22 are rotationally connected through a shaft sleeve 17 and a fixing bolt 18. Through holes are provided on both the fixing block 12 and the rotating shaft block 22. The shaft sleeve 17 passes through the through holes on the fixing block 12 and the rotating shaft block 22, and the fixing bolt 18 is inserted into the shaft sleeve 17, and the other end of the fixing bolt 18 is locked by a nut. When it is necessary to clean the sundries, the oil radiator 2 is rotated relative to the water radiator 1 around the shaft sleeve 17, thereby cleaning the sundries in the interlayer and reducing the cleaning difficulty.

[0040] like Figure 4 As shown, the fixing blocks 12 are provided in two groups with a total of four, each of which is composed of two fixing blocks 12. Two rotating shaft blocks 22 are provided, and each rotating shaft block 22 is rotatably connected to a group of fixing blocks 12. By providing two groups of rotational cooperation, the rotational connection strength of the oil radiator 2 and the water radiator 1 is enhanced, and the sagging degree of the oil radiator 2 is reduced.

[0041] like Figure 6 , Figure 7 As shown, a pair of L-shaped plates are provided on the right frame 13, and the L-shaped plates are installed on the side plates of the right frame 13 by screws. The L-shaped plates are arranged symmetrically up and down, and there is a set gap between the L-shaped plates to form the guide groove 15. The guide block 26 is a conical block. In the closed state, the thickness of the conical block at the end close to the water radiator 1 is less than the thickness at the end away from the water radiator 1. Since the guide block 26 contacts the guide groove 15 before the lock buckle 24 and the lock shaft 16 when the oil radiator 2 is closed, the lock buckle 24 and the lock shaft 16 are aligned through the guiding effect of the guide block 26 and the guide groove 15, so as to facilitate smooth locking.

[0042] like Figure 6 , Figure 7 As shown, the buffer column 14 is a rubber column, which is installed on the side of the right frame 13 facing the oil radiator 2, one on the top and one on the bottom. The limit baffle 25 is bent on the right support frame 23, the limit baffle 25 is perpendicular to the right side surface of the right support frame 23, and the limit baffle 25 is located in the middle of the right support frame 23. Before the oil radiator 2 contacts the water radiator 1, the limit baffle 25 is first pressed on the buffer column 14, and the cooperation between the limit baffle 25 and the buffer column 14 provides a limit and buffering effect to avoid vibration damage to the radiator when closing.

[0043] Based on the above radiator structure, an embodiment of the utility model further provides a loader, in which the loader is provided with the radiator structure described in the above embodiment. Since the above radiator structure has the above technical effects, the technical effects of the loader adopting the radiator structure please refer to the above embodiment.

[0044] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the protection scope of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the protection scope of the utility model.
