Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering vehicle cab technology, and in particular to a cab tilting mechanism. Background Technology
[0002] Most of the hydraulic and electrical components of mini excavators are located inside the machine's hood, which needs to be opened and closed frequently for maintenance of internal components. Therefore, a safe and practical tilting hinge mechanism needs to be designed. Utility Model Content
[0003] The purpose of this utility model is to provide a cab tilting mechanism with a reasonable structure that is easy to open and maintain.
[0004] To achieve the aforementioned objectives, this utility model provides a cab tilting mechanism, employing the following technical solution: A cab tilting mechanism, comprising: The machine cover body includes a cover plate, and a flange plate integrally formed with the cover plate is provided on the outer side of the cover plate; A flip hinge is installed inside the casing, wherein the flip end of the flip hinge is connected to a flange plate, and the flip hinge is concealed within the casing body; and The locking device of the flip hinge includes a safety pin facing a flange plate, the flange plate having a mounting hole for the safety pin to pass through. After the cover is opened, it automatically flips with the mechanism. Once flipped to a set angle, the safety pin automatically locks, ensuring safe operation for the user. After the user finishes operating the machine, the safety pin is released, and the cover slowly falls down with the flipping mechanism. The structure is reasonable and facilitates opening and maintenance.
[0005] A further improvement of this invention regarding a cab tilting mechanism is that the thickness of the flange plate is 1.2 to 1.5 times the thickness of the cover plate. The main body of the hood is made of high-strength steel plate, and the cover plate and flange plate are integrally stamped.
[0006] A further improvement of the cab tilting mechanism of this utility model is that the tilting hinge is fixed to the inner wall of the engine hood body by welding.
[0007] A further improvement of the cab tilting mechanism of this utility model is that the mounting hole is a tapered hole that matches the tapered head of the safety pin.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: After the cover is opened, it automatically flips with the mechanism. Once it flips to the set angle, the safety pin automatically locks to ensure safe operation by the user. After the user finishes operating, the safety pin is opened, and the cover slowly falls down with the flipping mechanism. The structure is reasonable and easy to open for maintenance. Attached Figure Description
[0009] Figure 1 This is a schematic diagram showing the opening of this utility model; Figure 2 This is a schematic diagram of the closing mechanism of this utility model.
[0010] The machine cover body 1 includes a cover plate 11, a flange plate 12, a flip hinge 2, a locking device 3, and a mounting hole 31. Detailed Implementation
[0011] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and not for limiting the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.
[0012] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0013] In the description of this utility model, it should be noted that the terms "vertical," "outer peripheral surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0014] Furthermore, terms such as "vertical" do not imply that a component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. Similarly, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.
[0015] like Figure 1-2 As shown, a cab tilting mechanism includes: The machine cover body 1 includes a cover plate 11, and a flange plate 12 integrally formed with the cover plate is provided on the outer side of the cover plate. A flip hinge 2 is installed inside the casing, wherein the flip end of the flip hinge is connected to a flange plate, and the flip hinge is concealed within the casing body; and The locking device 3 of the flip hinge includes a safety pin facing the flange plate, which has a mounting hole 31 for the safety pin to pass through. After the cover is opened, it automatically flips with the mechanism. Once flipped to a set angle, the safety pin automatically locks, ensuring safe operation for the user. After the user finishes operating the machine, the safety pin is released, and the cover slowly falls down with the flipping mechanism. The structure is reasonable and easy to open for maintenance.
[0016] Specifically, the thickness of the flange plate is 1.2 to 1.5 times the thickness of the cover plate. The main body of the cover is made of high-strength steel plate, and the cover plate and flange plate are integrally stamped.
[0017] Specifically, the flip hinge is fixed to the inner wall of the main body of the hood by welding.
[0018] Specifically, the mounting hole is a tapered hole that matches the tapered head of the safety pin.
[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
