Description

Technical Field

[0001] The utility model relates to the technical field of fire truck support frames, in particular to an adjustable support frame for a fire truck. Background Art

[0002] A fire truck is a vehicle specially used for fire fighting and rescue, usually equipped with a large water tank, a pump truck and a water spraying device to provide sufficient water at the fire scene.

[0003] Most of the existing water source adapters inside the fire truck body are fixed, and the specifications and sizes of the water source connectors on the fire trucks are the same. For fire trucks of different models and sizes, the height position, front and rear position, and upper and lower position of the water source connectors are different. When the valve of the water source connector is opened, the internal water pressure is very high and it cannot be installed in the air. It needs to be fixed by a support frame. However, due to the different positions of the water source connectors of fire trucks of different models and sizes, the production of different models of support frames according to needs is not only complicated, but also has many models and low versatility, which is not conducive to production, processing, sale, purchase, and replacement when damaged later. Therefore, a highly versatile adjustable support frame for fire trucks is proposed. Utility Model Content

[0007] A movable frame that can be movably adjusted in the vertical direction is movably installed between the two groups of fixed frames, and the movable frame is locked and fixed to the fixed frame by fixing bolts. Two groups of lower slide rails are symmetrically arranged on the upper surface of the movable frame, and a lower slider is slidably connected to the lower slide rails. An upper slide rail perpendicular to the direction of the lower slide rail is horizontally fixedly installed on the lower slider, and a slider positioning bolt that penetrates the lower slider and is supported on the lower slide rail is vertically arranged on the upper slide rail;

[0008] The upper slide rail is internally slidably connected to multiple groups of upper sliders, the side of the upper slide rail is horizontally provided with a strip-shaped through groove, the outside of the strip-shaped through groove is horizontally provided with a handle bolt threadedly connected to the upper slider, and a clamp for installing a pipe is fixedly installed on the upper slider.

[0009] Preferably, the fixing frame is welded inside the compartment of the fire truck.

[0010] Preferably, the foot cup is an elastic supporting foot.

[0011] Preferably, an elastic buffer pad is fixedly connected to the top end of the fixing frame.

[0012] Preferably, the movable frame is provided with an adjustment slot, and the adjustment slot is slidably connected to the surface of the fixed frame.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model arranges a fixed frame, a movable frame, a lower slide rail and an upper slide rail. According to the water source joints at different positions of the fire truck, the position of the movable frame is adjusted up and down after the fixed frame is fixed and installed, and the positions of the lower slide rail and the upper slide rail are adjusted front and back and left and right to achieve that the position of the clamp above the upper slide rail adapts to the position of the water source joint, thereby facilitating production, processing and installation. When the product is damaged due to long-term use, there is no need to worry about not being able to find a suitable model due to a long time of use. The purpose of high versatility is achieved, and the problem that the existing water source joint support frame on the fire truck has low versatility and is not conducive to production, processing, sale, purchase and later damage is solved.
