Description

Technical Field

[0001] This utility model relates to a fall prevention mechanism for the cover of a special operation vehicle, specifically a fall prevention mechanism for the cover of a three-in-one snowplow truck. Background Technology

[0002] A three-in-one snowplow typically has a snowplow at the front for shoveling snow, a roller brush at the bottom for rotating and sweeping snow, and a high-powered fan at the rear for blowing snow, achieving road snow removal through a triple structure.

[0003] The drive mechanism of the high-power blower in a three-in-one snowplow is usually located on the main frame of the vehicle and is covered by a cover when in operation. When it is inspected, the cover needs to be opened. However, the cover is generally not equipped with an effective anti-fall mechanism, and there may be a risk of falling when it is opened, which can easily cause personal injury. Utility Model Content

[0004] This utility model proposes a three-in-one snowplow cover anti-fall mechanism, the purpose of which is to overcome the above-mentioned shortcomings of the existing technology and prevent the cover from falling off.

[0005] The technical solution of this utility model is a three-in-one snowplow cover anti-fall mechanism, which includes a cover installed on the frame. One end of the cover is rotatably connected to the frame. An anti-fall mechanism is provided on the frame near the connection between the cover and the frame. When the cover is opened, the anti-fall mechanism rotates to the lower edge of one side of the cover and supports it. When the anti-fall mechanism rotates to the lower edge of the side of the cover away from the cover, the cover is closed.

[0006] Preferably, the anti-fall mechanism includes a mounting base installed on the vehicle frame, a support shaft vertically connected to the mounting base, one end of a stop bar rotatably connected to the support shaft via a bearing, a fixing block connected to the bottom of one end of the stop bar, the fixing block being fitted onto the support shaft, a screw rod connected to one side of the fixing block via a threaded through hole, and a locking handle connected to the outer end of the screw rod. When the vehicle cover is opened, the screw rod is released by the locking handle, preventing it from pressing against the support shaft, allowing the stop bar to rotate around the support shaft. When it rotates to the lower edge of one side of the vehicle cover, it can be supported, preventing the vehicle cover from falling. After rotating to the correct position, the screw rod is rotated in the opposite direction by the locking handle, pressing it against the support shaft, thus fixing the stop bar and preventing it from rotating. The opening of the vehicle cover can be adjusted by adjusting the contact position between the stop bar and the lower edge of one side of the vehicle cover. To close the vehicle cover, the opposite operation is performed.

[0007] The advantages of this utility model are: reasonable structural design, which can effectively fix the cover when it is open, simple operation, and adjustable opening within a range, which can effectively improve the safety during maintenance, and can be quickly adjusted when not in use without affecting the closing of the cover. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the anti-fall mechanism of the three-in-one snowplow cover of the utility model.

[0009] Figure 2 yes Figure 1 A schematic diagram of the fall arrest mechanism.

[0010] In the diagram, 1 is the frame, 2 is the carriage cover, 3 is the anti-fall mechanism, 31 is the mounting base, 32 is the support shaft, 33 is the bearing, 34 is the stop bar, 35 is the fixing block, 36 is the locking handle, and 37 is the screw. Detailed Implementation

[0011] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0012] like Figure 1 As shown, the three-in-one snowplow truck's cargo box cover anti-fall mechanism includes a cargo box cover 2 mounted on the frame 1. One end of the cargo box cover 2 is rotatably connected to the frame 1. An anti-fall mechanism 3 is provided on the frame 1 near the connection between the cargo box cover 2 and the frame 1. When the cargo box cover 2 is opened, the anti-fall mechanism 3 rotates to the lower edge of one side of the cargo box cover 2 and provides support. When the anti-fall mechanism 3 rotates to the lower edge of the side of the vehicle away from the cargo box cover 2, the cargo box cover 2 closes.

[0013] like Figure 2 As shown, the fall arrestor 3 includes a mounting base 31 mounted on the frame 1. A support shaft 32 is vertically connected to the mounting base 31. One end of the stop bar 34 is rotatably connected to the support shaft 32 via a bearing 33. A fixing block 35 is connected to the bottom of one end of the stop bar 34. The fixing block 35 is sleeved on the support shaft 32. A screw 37 is connected to one side of the fixing block 35 via a threaded through hole. A locking handle 36 is connected to the outer end of the screw 37.

[0014] According to the above structure, when the carriage cover 2 is opened, the screw 37 is released by the locking handle 36, so that it is not pressed against the support shaft 32. The baffle 34 can rotate around the support shaft 32. When it rotates to the lower edge of one side of the carriage cover 2, it can be supported to prevent the carriage cover 2 from falling. After rotating to the correct position, the screw 37 is rotated in the opposite direction by the locking handle 36 to press it against the support shaft 32, so that the baffle 34 can be fixed and not rotated. The opening of the carriage cover 2 can be adjusted by adjusting the contact position between the baffle 34 and the lower edge of one side of the carriage cover 2. When it is necessary to close the carriage cover 2, the opposite operation is performed. The anti-fall mechanism 3 does not interfere with the closing of the carriage cover 2.

[0015] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0016] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
