Description

Technical Field

[0001] The utility model relates to a limiting structure, in particular to a module component used for limiting the position of a turning plate of a special vehicle. Background Art

[0002] At present, livestock and poultry transportation in the market is mainly carried out by fence transport vehicles. During transportation, livestock and poultry are in an open-air state and are greatly affected by hot, cold, rainy and snowy weather, which can easily cause livestock and poultry, especially young livestock and poultry, to become sick and have a high mortality rate. At the same time, the feces produced during transportation will not only cause environmental pollution, but may also cause cross-regional spread of livestock and poultry.

[0003] In view of this, in order to overcome the shortcomings of ordinary fence transport vehicles, research and improvement are carried out on the existing problems, and a new type of livestock and poultry transport carriage is provided. The carriage is an aluminum alloy welded structure as a whole, which has the characteristics of light weight, high strength, and strong anti-corrosion performance. The compartment has a layered and fenced structure, which can effectively prevent livestock and poultry from getting injured in the process of transportation due to braking or uphill. The ventilation system and the spray drinking water system can ensure that long-distance transportation can be completed under extremely bad weather conditions, thereby improving the survival rate of livestock and poultry. For this reason, a constant temperature box for commercial pig transportation is designed, but the flap limit structure (latch) currently on the market cannot be directly used for this equipment, that is, there is a lack of a flap limit module component that can be integrated with the flap of the top plate of the constant temperature box. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a module assembly for limiting the flip panel of a special vehicle.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a module assembly for limiting the flap of a special vehicle, comprising a flap limiting fixing plate and a flap limiting rod, the two ends of the flap limiting fixing plate are bent upward, the flap limiting rod passes through the bent parts of the two ends of the flap limiting fixing plate, the two ends of the flap limiting rod are located outside the flap limiting fixing plate, and one end is bent to form a handle structure, the flap limiting rod above the main body of the flap limiting fixing plate is provided with a gear lever perpendicular to it, and the gear lever is away from the handle structure, a vertical limit stop column is fixed on the surface of the flap limiting fixing plate between the gear lever and the handle structure, and a compression spring is sleeved on the flap limiting rod between the gear lever and the handle structure.

[0006] Furthermore, the two ends of the compression spring are respectively in close contact with the shift lever and the inner side surface of the bent portion of the flap limit fixing plate, and when the compression spring is in a normal state, the shift lever and the limit stop column cross and are perpendicular.

[0007] Furthermore, the handle structure and the gear lever are arranged parallel to each other.

[0008] Furthermore, a flat washer is fixed to the outer side wall of the bent portion of the flap limiting fixing plate at one end of the handle structure, and the flap limiting rod passes through the flat washer.

[0009] Furthermore, a plurality of fixing holes are provided on the surface of the flap limiting fixing plate body.

[0010] Furthermore, the width of the bent parts at both ends of the flap limiting fixing plate is smaller than the main body width of the flap limiting fixing plate.

[0011] Furthermore, the fixed position of the limit stop post satisfies that the shift rod and the limit stop post intersect to compress the compression spring by one half.

[0012] The utility model is used for being installed on the side of opening the top plate flap of the constant temperature transportation box of commercial pigs, manually pulling the handle structure to move the flap limit rod, so that the gear lever is at the rear side of the limit stop column to prevent the compression spring from rebounding, that is, the limit end of the flap limit rod away from the handle structure no longer presses the flap, so that the flap can be normally opened and closed during loading and unloading or cleaning. After the flap is closed, the flap limit rod is rotated to disengage from the limit, and the compression spring is automatically rebounded to the natural state of the compression spring, and the limit end of the flap limit rod is pressed on the upper surface of the top plate flap again to achieve the flap limiting effect; the structure is not only simple and convenient to operate, but also can effectively prevent the flap limit rod from moving during transportation and causing the top plate flap to be opened due to bumps through the supporting effect of the compression spring, so as to ensure the safety during transportation. In addition, when opening, because the compression spring also has torsional resistance, the gear lever can be firmly contacted with the limit stop column, effectively preventing the gear lever from separating from the limit stop column when in the open state, and preventing the flap limit rod from rebounding and locking the top plate flap.

[0016] like Figure 1-2 The present invention shows a module component for limiting the flap position of a special vehicle, comprising a flap limiting fixing plate 1 and a flap limiting rod 2, both ends of the flap limiting fixing plate 1 are bent upward, the flap limiting rod 2 passes through the bent parts of both ends of the flap limiting fixing plate 1, both ends of the flap limiting rod 2 are located outside the flap limiting fixing plate 1, and one end is bent to form a handle structure 3, the flap limiting rod 2 above the main body of the flap limiting fixing plate 1 is provided with a shift rod 4 perpendicular to it, and the shift rod 4 is away from the handle structure 3, a vertical limit stop column 5 is fixed on the surface of the flap limiting fixing plate 1 between the shift rod 4 and the handle structure 3, and a compression spring 6 is sleeved on the flap limiting rod 2 between the shift rod 4 and the handle structure 3.

[0017] The two ends of the compression spring 6 are respectively tightly attached to the shift rod 4 and the inner side of the bent part of the flap limit fixing plate 1, and when the compression spring 6 is in normal state, the shift rod 4 and the limit stop column 5 are crossed and perpendicular, the handle structure 3 and the shift rod 4 are arranged parallel to each other, and a flat washer 7 is fixed to the outer wall of the bent part of the flap limit fixing plate 1 at one end of the handle structure 3, and the flap limit rod 2 passes through the flat washer 7.

[0018] The surface of the main body of the flap limit fixing plate 1 is provided with multiple fixed mounting holes 8.
