Description

Technical Field

[0001] The utility model relates to the field of fire fighting equipment, in particular to a pair of fast net breaking fire fighting pliers. Background Art

[0002] In firefighting operations, pliers are frequently used, such as cutting plates, cutting cables, breaking mesh frames, etc. Due to the complexity of firefighting operations, it is sometimes necessary to break the obstructing mesh frame to allow people or tools to pass through to complete the operation. Traditional pliers are used to cut each wire on the mesh frame separately. When a sufficient number of wires are cut in parallel, the mesh is broken and a long slit is produced. However, since traditional pliers can only cut the wires on the mesh frame one by one, it takes a very long time, delaying the operation time; and traditional pliers require both hands to hold the pliers body and then open and close the pliers to complete the cutting, which is very laborious to repeat many times.

[0003] Therefore, the existing fire-fighting pliers need to be further improved. Utility Model Content

[0004] In view of the above-mentioned prior art, the technology to be achieved by the utility model is: multiple mesh wires can be quickly sheared to break the mesh, and the force application method is unidirectional force application, which is more labor-saving.

[0005] In order to achieve the above purpose, the utility model adopts the following scheme:

[0006] A quick net-breaking fire-fighting pliers comprises a pliers body, the pliers body comprises a pin which can be inserted into a mesh hole and a pliers foot which can rotate relative to the pin, a pliers cutter which can cut a plurality of meshes at a time is arranged on the pliers body, a foldable driving connection is arranged on the pliers body, a pressure component for driving the pliers body to cut is arranged on the driving connection, and the pressure component can be installed and removed from the driving connection.

[0007] Furthermore, the plug pin and the top of the clamp foot in the utility model are hingedly connected.

[0008] Furthermore, the mesh clamp cutter in the utility model comprises a blade arranged on the clamp foot and on a wall surface on one side opposite to the plug foot, the blade is provided with a plurality of arc-shaped slots for inserting mesh wires, and the arc-shaped slots are provided with cutting edges.

[0009] Furthermore, a sharp tooth-shaped inserting tooth which can be inserted into the mesh is formed between every two arc-shaped notches in the utility model.

[0010] Furthermore, a knife groove for inserting a blade is arranged on the wall surface of the plug pin opposite to the pliers leg in the utility model.

[0011] Furthermore, the driving connector in the utility model includes an inner cavity arranged on both sides of the pin and two through holes connected from the inner cavity to the outside, a connecting plate that can move linearly left and right is limitedly arranged in the inner cavity, buttons and T-shaped nails are respectively fixed on the upper and lower ends of the connecting plate and are respectively placed in the two through holes, and a spring is arranged between the connecting plate and the relative wall of the inner cavity.

[0012] Furthermore, the pressure-applying component in the utility model comprises a rod handle, support rods are hinged on the left and right sides of the lower part of the rod handle, and hook grooves for inserting T-shaped nails are arranged on the support rods.

[0013] Furthermore, a cylindrical pressing piece for pressing the outer wall surface of the pliers foot is arranged at the lower end of the rod handle in the utility model.

[0014] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0015] The utility model can insert the pin into the mesh hole so that the mesh wire is between the pin and the clamp foot. Due to the rotational connection between the two, after the pressure-applying component is connected to the driving connector, the mesh wire between the clamp foot and the pin can be quickly cut one by one by the clamp cutter when the user applies force. The whole process does not need to repeatedly open and close the jaws of the clamp to achieve each mesh wire, and the clamping speed is faster. The activation of the pressure-applying component is achieved by the user's unidirectional force, and can even be completed by pressing down with the body weight, which can quickly cut and save effort.

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0021] like Figures 1 to 4The fast mesh breaking fire pliers shown in the figure include a pliers body, the pliers body includes a pin 1 that can be inserted into a mesh hole and a pliers foot 2 that can rotate relative to the pin 1, a mesh cutter 3 that can cut multiple meshes at a time is arranged on the pliers body, a foldable driving connection 4 is arranged on the pliers body, a pressure component 5 for driving the pliers body to cut is arranged on the driving connection 4, and the pressure component 5 can be installed and removed from the driving connection 4. The pin is in the shape of a straight rod as a whole, and can be inserted into a mesh hole that is larger than the length and width of the pin. According to actual use, it can be inserted into a mesh hole with a size of 5cm*5cm or more. After the pin is inserted, the pin and the pliers foot can be rotated, so that the pin and the pliers foot naturally hang down, and the mesh frame is between the two. When the two are close to each other through the force applied by the user, the mesh cutter will cut multiple meshes on the mesh frame. The user applies force by first inserting the pressure component from one side of the pliers foot through the mesh hole into the driving connector of the pin, and then applying unidirectional force by holding the pressure component to bring the pin and the pliers foot closer to each other, so that the pliers cutter cuts the mesh wire.

[0022] The plug pin 1 and the pliers foot 2 described in the utility model are hingedly connected at the top. The plug pin and the pliers foot can be rotated at the top as a hinge point. After the plug pin is inserted into the mesh, the plug pin and the pliers foot are rotated so that the plug pin and the pliers foot are in a close position to prepare for clamping and cutting.

[0023] The mesh clamp cutter 3 of the utility model includes a blade 31 arranged on the clamp foot 2 and on the wall surface on one side opposite to the plug pin 1, and the blade 31 is provided with a plurality of arc-shaped notches 32 for inserting mesh wires, and the arc-shaped notches 32 are provided with blades 33. The arc-shaped notches on the blade can accommodate mesh wires stuck therein, and when the plug pin and the clamp foot are close to each other, the mesh wires therein will be squeezed and cut by the blades and the knife grooves, thereby breaking. Since the hinge point between the plug pin and the clamp foot is arranged at the top, when the mesh wires are inserted into the arc-shaped notches, the clamp body is in an inverted V shape as a whole, and the arc-shaped notches on the upper side will first cut the mesh wires, until each mesh wire in the arc-shaped notches is gradually cut from top to bottom, and the mesh breaking is completed.

[0024] In the utility model, a sharp tooth-shaped inserting tooth 6 that can be inserted into the mesh is formed between each two arc-shaped notches 32. In order to avoid the protrusion between the arc-shaped notches being too large, the distance between the arc-shaped notches should be close so that the protrusion forms a sharp tooth-shaped inserting tooth.

[0025] The plug pin 1 of the utility model is provided with a knife groove 7 for inserting a blade 31 on the wall surface on one side opposite to the pliers foot 2. The knife groove is a groove-shaped space capable of accommodating the blade. When the blade is fully inserted, the mesh wire in the arc groove is squeezed and cut by the blade and the knife groove, thereby breaking it.

[0026] The driving connector 4 in the utility model includes an inner cavity 41 provided on both sides of the pin 1 and two through holes 42 connected from the inner cavity to the outside. A connecting plate 43 that can move linearly left and right is limitedly arranged in the inner cavity 41. A button 44 and a T-shaped nail 45 are respectively fixed on the upper and lower ends of the connecting plate 43 and are respectively placed in the two through holes 42. A spring 46 is arranged between the connecting plate 43 and the opposite wall of the inner cavity 41. The driving connector is used to connect the pressure component. During the insertion of the pin into the mesh, in order to prevent interference, the button can be pressed to press the connecting plate into the inner cavity. At this time, the spring shrinks, and the T-shaped nail is also retracted in the inner cavity from the through hole. After passing through the mesh, the button is released to reset the spring to reset the T-shaped nail and the button. After resetting, the user can immediately connect the pressure component with the T-shaped nail.

[0027] The pressure-applying component 5 in the utility model includes a handle 51, and support rods 52 are hinged on the left and right sides of the lower part of the handle 51, and hook grooves 53 for inserting T-shaped nails 45 are arranged on the support rods 52. When connecting, the two support rods are passed through the mesh and connected to the T-shaped nails on one side of the pliers foot. Specifically, the hook grooves on the two support rods are respectively inserted into the T-shaped nails, and they can be inserted one by one to achieve the connection between the two support rods and the T-shaped nails. After installation, the handle is on one side of the pliers foot. By turning the handle downward, the bottom end of the handle will press against the outer wall of the pliers foot and pull the T-shaped nail at the same time to make the plug and the pliers foot close to each other until the mesh wire is cut by the pliers.

[0028] The lower end of the rod handle 51 described in the utility model is provided with a cylindrical pressing piece 8 for pressing the outer wall surface of the pliers foot 2. Being provided as a cylindrical pressing piece can make the rod handle push the pliers foot more smoothly.
