detailed description

The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

The on-site rescue device for traffic accidents of the present invention, as shown in Figures 1 and 2, includes a demolition pliers 3, and the demolition pliers 3 control the opening and closing of the jaws through the transmission of a transmission mechanism. Transmission mechanism comprises screw mandrel 6, and screw mandrel 6 is sheathed with push nut 7, and the pliers handle of demolition pliers 3 is connected to push nut 7 through connecting force arm 4; Realize the crank handle 8 that controls the opening and closing of the jaws of the demolition pliers 3 . The screw mandrel 6 is a screw thread structure, and the screw nut 7 has an internal thread structure. The crank handle 8 drives the screw screw 6 to rotate, and simultaneously drives the push nut 7 to advance or retreat, so as to realize the opening and closing of the demolition pliers 3 jaws.

In the present invention, the crank handle 8 is provided with a polygonal wrench hole 83 that engages with the end of the screw rod 6. After the crank handle is put on, the torque is transmitted to drive the screw rod 6 to rotate, and the operation is labor-saving. The two-way ratchet 85 is set on the handle 8 behind the wrench hole 83, and only needs a small reciprocating rotation to drive the wrench hole 83 to rotate. When turning the handle, there is no need to turn the handle 8 360 degrees, and it can be used without being affected by space. . One end of the crank handle 8 near the wrench hole 83 is provided with a protruding crowbar head 81, and the top end is provided with a crowbar fulcrum 82, which acts as a fulcrum when the crowbar is in use. The crowbar head 81 is used to pry open the deformed car body or use it as a hammer to knock the window glass.

The traffic accident site rescue device of the present invention, as shown in Figure 3, the end of the crank handle 8 opposite to the wrench hole 83 is a wrench handle 84, and the end of the wrench handle 84 is rotatably connected with a blade 9 and a saw blade 10, and the wrench handle 84 The end is provided with the groove body that can accommodate blade 9 and saw blade 10, and blade 9 and saw blade 10 can be rotatably unscrewed and used or screwed in and hidden in the groove body. For ease of operation, a push-up button 11 that can be pressed to push up the blade 9 and the saw blade 10 in the tank is provided on the side wall of the handle 8, so that the blade 9 and the saw blade 10 can be unscrewed. Knife and saw are received in the rocking handle 8 when not being used at ordinary times, can push knife or saw with this push button during use, then pull up knife or saw with finger again. Saw blade 10 is used for cutting deformed car body, and blade 9 can cut safety belt or other braids on the car to rescue trapped personnel.

The screw mandrel 6 is supported and connected on the body of the demolition pliers 3 by the connecting rod 5, and the connecting end of the screw mandrel 6 and the connecting rod 5 can rotate relatively. The end of the connecting rod 5 is a spherical structure nested in the end of the screw mandrel 6 or the junction of the connecting rod 5 and the screw mandrel 6 is provided with a thrust bearing to facilitate the rotation of the screw mandrel 6 . This structure improves the stability of the screw rod 6 without affecting the adjustment and rotation of the screw rod. The adjusting end of the screw rod 6 is supported in the groove structure of the upper and lower housings, and the other end is supported by the connecting rod 5. When the screw rod 6 is rotated, the nut 7 moves relative to the screw rod, and the jaws of the demolition pliers 3 are driven by the connecting force arm 4 Open up.

The demolition pliers 3 are made of high-strength steel, and the connecting arm 4 is connected to the rear handle of the demolition pliers 3 and the push nut 7 . Open the jaws and demolish the deformed car body.

Breaking pliers 3 outer cover has shell, and shell can select plastic material for use, protects breaking pliers 3 and internal components, and shell comprises detachable lower shell 1 and upper shell 2, is convenient to dismantling installation and maintenance. The jaws of the breaching pliers 3 protrude from the front end of the shell, and the hinge of the jaws is connected to the shell by a fixed pin 31. Fixing pin 31 fixes the upper and lower shells and the jaws of the demolition pliers, and plays a positioning role.

In the present invention, the lower side of the upper housing 2 is provided with a non-slip handle 22 for easy handling and operation, which can also be used as a handle of the demolition pliers, and is also a handle during work, which is easy to carry and use; the upper housing 2 is provided with a reinforced The ribs 21 increase the strength of the casing.

The on-site rescue device for traffic accidents of the present invention, when in use, turns the crank handle 8 to drive the screw rod 6 to rotate, and opens the jaws of the demolition pliers 3 through the connection arm 4, and the jaws expand to open the deformed car body or door window; the crank handle 8 It can be used as a hammer to knock on the window glass; the crowbar design in the crank handle 8 can pry off the stuck deformed car body; the hidden saw blade 10 can saw the deformed car body (metal or plastic components) after opening; After the blade 9 hidden in the crank handle is opened, the safety belt or other fabrics can be cut off, and the trapped personnel are rescued successfully.

The invention is a traffic accident on-site rescue device designed for quickly rescuing people trapped in traffic accidents. The device is compact in structure, small in size and easy to carry with the vehicle, convenient and quick to use, and can greatly save rescue time. In a traffic accident, the deformation of the car body often makes the occupants unable to get out of trouble. Before the professional rescuers arrive at the scene, the people in other vehicles or the passing masses are helpless because they do not have professional tools. The invention can be used as an easy-to-carry and use rescue device for a private car, and can be used to quickly and timely rescue people trapped in the accident car when a traffic accident occurs, and has a good application prospect.

The present invention has been exemplarily described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned manner, as long as various insubstantial improvements or direct application to other occasions are carried out by adopting the method concept and technical solutions of the present invention, All fall within the protection scope of the present invention.
