Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling system technology, and in particular to a rear cover limiting mechanism for skid steer loaders. Background Technology
[0002] Due to the compact interior space of skid steer loaders, high maintainability is required. Therefore, the rear cover of skid steer loaders is designed to be rotatable and openable to facilitate maintenance inside the cab. To ensure safety during maintenance after the rear cover is opened, a mechanical limit is installed to prevent abnormal movement of the rear cover during the maintenance process.
[0003] In existing technologies, the mechanical limiting devices of skid steer loaders are mostly support rods or pins. These support rods or pins are fixed to the rear cover. After the rear cover is rotated open, the support rod or pin must be manually removed and placed into the limiting hole in the frame to achieve rear cover limiting. In actual operation, the manual limiting design is prone to problems due to improper operation, such as omissions in the limiting operation steps or a lack of safety awareness, which may lead to failure to manually limit the rear cover, resulting in significant safety hazards. Summary of the Invention
[0004] In view of this, the present invention provides a rear cover limiting mechanism for skid steer loaders, which can automatically limit the rear cover of skid steer loaders.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

The bottom plate of the fixed seat has a limit hole, and the bottom plate of the rotating seat has a limit notch. The limit plate is movably mounted on the fixed seat, and the lower part of the limit plate is inserted into the limit hole. During the opening of the rear cover, when the limit hole and the limit notch are vertically aligned, the limit plate automatically falls under the action of gravity and locks into the limit notch, thus limiting and fixing the rear cover. During the closing of the rear cover, the limit plate is first pushed upward out of the limit notch, and then the rear cover is closed.
[0008] Preferably, the limiting hole is a square hole; the fixing base includes a vertical plate, which is vertically installed between the top plate and the bottom plate of the fixing base, the outer surface of the vertical plate is flush with one side of the square hole, and the limiting plate is movably installed on the vertical plate.
[0009] Preferably, the limiting plate has an elongated hole; the outer surface of the upright plate is provided with an outwardly extending guide pin, and the elongated hole cooperates with the guide pin, so that the limiting plate can be movably mounted on the upright plate.
[0010] Preferably, the outer surface of the limiting plate is provided with a limiting contact plate extending outward.
[0011] Preferably, the lower width of the limiting plate is smaller than the upper width.
[0012] Preferably, the upright plate has weight-reducing holes, and multiple weight-reducing holes are provided.
[0013] Preferably, the rotating base includes a reinforcing plate, which is vertically installed between the top plate and the bottom plate of the rotating base.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0027] The following is for reference. Figures 1 to 4 This invention describes a rear cover limiting mechanism for a skid steer loader in an embodiment of the present invention.
[0028] This application discloses a rear cover limiting mechanism for a skid steer loader, comprising: a fixed base 1, a limiting plate 2, and a rotating base 3.
[0029] The fixed seat 1 is fixedly connected to the frame 4, and the rotating seat 3 is fixedly connected to the rear cover 5. The fixed seat 1 and the rotating seat 3 are hinged together. The bottom plate of the fixed seat 1 has a limiting hole 11, and the bottom plate of the rotating seat 3 has a limiting notch 31. The limiting plate 2 is movably mounted on the fixed seat 1, and the lower part of the limiting plate 2 is inserted into the limiting hole 11. During the opening of the rear cover 5, when the limiting hole 11 and the limiting notch 31 are vertically aligned, the limiting plate 2 automatically falls down under the action of gravity and is locked into the limiting notch 31 to limit and fix the rear cover 5. During the closing of the rear cover 5, the limiting plate 2 is first pushed upward out of the limiting notch 31, and then the rear cover 5 is closed.
[0030] For example Figure 1As shown, both the fixed seat 1 and the rotating seat 3 are C-shaped structures, with their backs fixedly connected to the frame 4 and the rear cover 5, respectively. The fixed seat 1 is hinged to the rotating seat 3, and the fixed seat 1 is located inside the rotating seat 3. When the rear cover 5 is closed, the limiting hole 11 on the bottom of the fixed seat 1 and the limiting notch 31 on the bottom of the rotating seat 3 are misaligned. At this time, the limiting plate 2 cannot fall out of the limiting hole 11. When the rear cover 5 is open, the limiting hole 11 on the bottom of the fixed seat 1 can be aligned with the bottom of the rotating seat 3. When the upper limit notch 31 is aligned vertically, the limit plate 2 can automatically fall from the limit hole 11 and insert into the limit notch 31 to achieve the limit fixation of the rear cover 5. At this time, the rear cover 5 cannot be closed. When it is necessary to close the rear cover 5, first push the limit plate 2 upward out of the limit notch 31, and then close the rear cover 5. At this time, the limit hole 11 and the limit notch 31 are misaligned again, the limit plate 2 cannot fall into the limit notch 31, the limit plate 2 fails to limit, and the rear cover 5 can be closed normally.
[0031] By setting the limiting mechanism of this application, the rear cover 5 can be automatically limited after it is opened, thus completely avoiding the defect of manual limiting in the prior art, which is easy to forget and thus leads to safety accidents, and significantly improving the construction safety after the rear cover 5 is opened.
[0032] In some embodiments, for example Figure 2 As shown, the limiting hole 11 is a square hole; the fixing base 1 includes a vertical plate 12, which is vertically installed between the top plate and the bottom plate of the fixing base 1. The outer surface of the vertical plate 12 is flush with one side of the square hole. The limiting plate 2 is movably installed on the vertical plate 12, which can ensure that the limiting plate 2 can move freely in the vertical direction. At the same time, the setting of the vertical plate 12 can also strengthen the structural strength of the fixing base 1.
[0033] Furthermore, the limiting plate 2 has an elongated hole 21; a guide pin 121 extending outward is provided on the outer surface of the upright plate 12. The elongated hole 21 cooperates with the guide pin 121, allowing the limiting plate 2 to be movably mounted on the upright plate 12. The cooperation between the elongated hole 21 and the guide pin 121 guides the up-and-down movement of the limiting plate 2, making the up-and-down movement of the limiting plate 2 more stable, preventing deviation, and preventing the limiting plate 2 from jamming and causing limiting failure.
[0034] In some embodiments, for example Figure 2 As shown, a limiting contact plate 22 extending outward is provided on the outer surface of the limiting plate 2. The limiting contact plate 22 provides an operating point for the operator to apply force, making it easier for the operator to move the limiting plate 2 and thus saving effort.
[0035] In some embodiments, for example Figure 3As shown, the lower width of the limiting plate 2 is smaller than the upper width. This design facilitates the installation of the limiting plate 2.
[0036] In some embodiments, for example Figure 2 As shown, the upright plate 12 is provided with weight reduction holes 122. Multiple weight reduction holes 122 are provided, and the multiple weight reduction holes 122 can effectively reduce the weight of the upright plate 12.
[0037] In some embodiments, for example Figure 4 As shown, the rotating base 3 includes a reinforcing plate 32, which is vertically installed between the top plate and the bottom plate of the rotating base 3. The reinforcing plate 32 can effectively enhance the structural strength of the rotating base 3.
