Technical Field

[0001] The utility model belongs to the field of steering oil tanks of commercial vehicle steering systems, and in particular relates to a steering oil tank upper cover with rainproof and dustproof functions. Background Art

[0002] Most commercial vehicles prefer to place steering system components in the space below the cab. However, with the diversity of commercial vehicle product types and increasingly stringent restrictions on the places where commercial vehicles are used, commercial vehicle cabs usually have aisles, stairs, and height reductions, resulting in the space below the cab becoming increasingly compact, leaving less and less space for the placement of steering system components.

[0003] For vehicles with limited space under the cab (such as vehicles with lowered cabs and vehicles with stepped cabs), there is no space for the steering oil tank under the cab, so the steering oil tank can only be arranged outside the cab. Therefore, higher requirements are placed on the waterproof ability of the steering oil tank cover. The traditional steering oil tank cover is no longer suitable for this usage condition. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a steering oil tank cover with rain and dustproof functions to solve the problem that the steering oil tank is exposed outdoors due to space limitations and is easily infiltrated with water, causing the steering fluid to deteriorate and turn white.

[0024] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0025] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0026] Example 1

[0027] like Figure 1 As shown, there is no shielding between the bottom end of the steering oil tank cover and the upper end surface of the oil tank body 4 in the prior art. When it rains, a large amount of rainwater is easily accumulated in this area, which not only affects subsequent operations, but also the rainwater is easily splashed into the gap between the cover body and the inlet 6 and leaks in, even causing the oil to deteriorate and turn white.

[0028] In order to avoid the above problems, Figure 2-3 As shown, this embodiment provides a steering oil tank cover with rain and dustproof functions, including:

[0029] Steering oil tank upper cover body 1;

[0030] A cylindrical protective eave 3, wherein the protective eave 3 is coaxially sleeved on the outside of the oil tank body 4, the inner wall of the protective eave 3 is gap-matched with the outer wall of the oil tank body 4, the bottom end of the protective eave 3 is lower than the upper end surface of the oil tank body 4, and the top end of the protective eave 3 is higher than the upper end surface of the oil tank body 4;

[0031] The funnel-shaped connector 2, the oil tank body 4 is a cylindrical structure, the corresponding end face of the protective eaves 3, the large end and the small end of the connector 2 are all circular structures, and the large end of the connector 2 has the same diameter as the protective eaves 3, the large end of the connector 2 is coaxially sealed and connected to the top of the protective eaves 3, the small end of the connector 2 has the same diameter as the steering oil tank upper cover body 1, and the small end of the connector 2 is coaxially sealed and connected to the bottom end of the steering oil tank upper cover body 1.

[0032] In this embodiment, the steering oil tank upper cover body 1 is coaxial with the oil tank body 4, that is, the steering oil tank upper cover body 1 is coaxial with the protective eaves 3, so that when the steering oil tank upper cover body 1 is rotated, the connecting part 2 and the protective eaves 3 can be driven to rotate synchronously, and the inner wall of the protective eaves 3 is always in clearance fit with the outer wall of the oil tank body 4, and no interference will occur.

[0033] Therefore, the steering oil tank cover provided in this embodiment integrates the steering oil tank cover body 1, the connecting piece 2 and the protective eaves 3 into one, so that the oil tank cover is made into a stepped shape. The first step is used to apply force to the tank cover by hand when opening or tightening the oil tank, and the second step is used to cover the upper outer edge of the tank body. It can not only prevent dust, but also during rain, rainwater will flow along the outer edge of the cover and will not accumulate. At the same time, a certain gap is reserved to ensure the air permeability of the oil tank, preventing rainwater from splashing or leaking into the oil tank through the upper part of the tank body or side blowing, causing the oil to deteriorate and turn white.

[0034] In this embodiment, a steering oil tank upper cover connector 5 is coaxially fixed inside the steering oil tank upper cover body 1, a first external thread is fixed on the outer wall of the steering oil tank upper cover connector 5, a first internal thread matching the first external thread is fixed on the inner wall of the inlet 6 at the top of the oil tank body 4, and the steering oil tank upper cover connector 5 is screwed and fixed to the inlet 6.

[0035] By rotating the steering oil tank upper cover body 1, the steering oil tank upper cover connector 5 can be driven to rotate synchronously, so that the steering oil tank upper cover connector 5 can be disassembled or installed, which is convenient to operate.

[0036] A sealing gasket 7 is provided between the steering oil tank upper cover connector 5 and the inlet 6. The sealing gasket 7 can enhance the sealing performance between the steering oil tank upper cover connector 5 and the inlet 6.

[0037] like Figure 4 As shown, in this embodiment, the large end of the connector 2 can be screwed and fixed to the top of the protective eaves 3. In this way, the connector 2 and the protective eaves 3 can be disassembled or assembled at any time, and the operation is simple and convenient. When not in use, the protective eaves 3 can be disassembled for easy storage.

[0038] For example, a lower extension ring 8 is coaxially fixed on the end face of the large head end of the connecting member 2, and a lower annular groove 9 matching the lower extension ring 8 is coaxially opened on the top end face of the protective eaves 3, a second external thread is fixed on the outer wall of the lower extension ring 8, and a second internal thread matching the second external thread is fixed on the inner wall of the lower annular groove 9, the lower extension ring 8 is embedded in the lower annular groove 9, and the second external thread is screwed and fixed to the second internal thread.

[0039] In this way, the protective eaves 3 can be removed by rotating the protective eaves 3, and the operation is very convenient.

[0040] Similarly, the small end of the connector 2 can be screwed and fixed to the bottom end of the steering oil tank upper cover 1. Its structural principle is similar to the above structure.

[0041] Example 2

[0042] When the end face of the oil tank body 4 is a square, the corresponding end face of the protective eaves 3 is also a square. At this time, the protective eaves 3 cannot rotate around the oil tank body 4. In this way, when the steering tank upper cover 1 is rotated, the protective eaves 3 and the oil tank body 4 will interfere with each other.

[0043] In order to avoid the above problems, based on Example 1, in this embodiment, the small end of the connector 2 is circular, and is rotatably sealed and connected to the bottom end of the steering oil tank upper cover body 1. At this time, the internal size of the connector 2 is still gradually increasing from top to bottom, but the large end of the connector 2 is square, which is compatible with the protective eaves 3. At this time, when the steering oil tank upper cover body 1 is rotated, the small end of the connector 2 and the bottom end of the steering oil tank upper cover body 1 rotate relative to each other, that is, the connector 2 does not rotate synchronously with the steering oil tank upper cover body 1, so that the protective eaves 3 can be prevented from interfering with the oil tank body 4.

[0044] For example, an upper extension ring 10 is fixed on the end face of the small head of the connecting member 2, and a limiting ring 11 is coaxially fixed on the upper extension ring 10 away from one end of the connecting member 2. An upper annular groove 12 adapted to the upper extension ring 10 is provided on the bottom end face of the steering oil tank upper cover body 1, and a limiting groove 13 adapted to the limiting ring 11 is provided in the steering oil tank upper cover body 1, and the limiting groove 13 is connected with the upper annular groove 12, and the limiting ring 11 is embedded in the limiting groove 13, and the upper extension ring 10 is located in the upper annular groove 12, and the size of the limiting ring 11 is larger than the size of the upper annular groove 12, so that the limiting ring 11 cannot be directly detached from the upper annular groove 12, and due to the effect of gravity, the lower end face of the limiting ring 11 can conflict with the inner bottom face of the limiting groove 13, thereby forming a sealing structure.

[0045] When the steering oil tank upper cover body 1 is rotated, the limiting ring 11 can rotate in the limiting groove 13, and the upper extension ring 10 can rotate in the upper annular groove 12, that is, when the steering oil tank upper cover body 1 is rotated, the connecting piece 2 may not rotate and always maintain a sealed connection state.

[0046] Example 3

[0047] When the inlet 6 is not coaxial with the oil tank body 4, that is, the inlet 6 is an eccentric inlet, the connecting piece 2 is an eccentric funnel, that is, the small end and the large end of the connecting piece 2 are not coaxial, so when the steering tank upper cover 1 is rotated, the protective eaves 3 and the oil tank body 4 will interfere with each other.

[0048] In order to avoid the above problems, based on Example 1, in this embodiment, the connecting member 2 is an eccentric funnel structure, and the small end and the large end of the connecting member 2 are both circular, but not coaxial. At this time, when the steering oil tank upper cover body 1 is rotated, the small end of the connecting member 2 and the bottom end of the steering oil tank upper cover body 1 rotate relative to each other, that is, the connecting member 2 does not rotate synchronously with the steering oil tank upper cover body 1, so that the protective eaves 3 can be prevented from interfering with the oil tank body 4.

[0049] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
