Description

Technical Field

[0001] The present application relates to the technical field of firefighting and demolition equipment, and more specifically, to an insulating scissors cup for firefighting and rescue. Background Art

[0002] In daily work, we not only have to face fire fighting, but also scenes such as traffic accidents, earthquake rescue, and high-altitude demolition, which have newer and higher requirements for various application equipment. At present, at the scene of fire fighting and rescue, there are common safety hazards of electric shock. It is impossible to find the power-off switch inside or outside the building in the first time. Fire rescue personnel rashly enter the rescue site to carry out reconnaissance and rescue, water discharge and fire fighting without completely cutting off the power, which can easily put fire rescue personnel and surrounding people in danger of electric shock. Among the existing power-off equipment, there is a lack of a cutting device that is easy for fire rescue personnel to carry flexibly and can help the carrying personnel to safely and effectively implement the power-off operation.

[0003] The existing ceramic insulated scissors are not long enough to help firefighters cut wires that are high above the ceiling. Electrician's scissors are mostly made of conductive materials. Using scissors made of such materials during live operations can easily cause a short circuit in the line and pose a safety threat to rescue workers. At the same time, electrician's scissors are limited in length and cannot help firefighters cut wires at high places.

[0004] In order to solve the above problems, the present application provides an insulating scissors cup for firefighting and rescue. Utility Model Content

[0005] The insulated scissors cup for fire rescue provided in this application adopts the following technical solution:

[0006] An insulating scissors cup for firefighting and rescue comprises a cup body, a cup cover is rotatably sleeved on the top outer wall of the cup body, a sleeve cover is provided at one end of the cup cover away from the cup body, a cross clamping block is provided at the center position of the inner bottom of the sleeve cover, a shearing mechanism is provided in the cup body, and the shearing mechanism runs through the cup body, a surrounding external thread is provided on the top outer wall of the cup body, a symmetrical make way groove is penetrated through the top of the cup body, an annular external clamping ring is provided on the top of the outer wall of the cup body, and the external clamping ring is located above the external thread, a surrounding internal thread is provided at the bottom of the inner wall of the cup cover, and an annular internal clamping ring is provided at the middle position of the inner wall of the cup cover.

[0007] Furthermore, the outer clamping ring and the inner clamping ring are clamped together, and the outer thread and the inner thread are threadedly connected to each other.

[0008] Furthermore, the shearing mechanism includes a rotating rod, a rotating block is provided on one end of the rotating rod, a limiting rotating head is provided on the end of the rotating rod away from the rotating block, a rotating ring is rotatably sleeved on the outer wall of the limiting rotating head, a symmetrical linkage rod is provided on the outer wall of the rotating ring, and scissors are provided on the end of the linkage rod away from the rotating ring, an abutment sleeve is provided in the middle position of the inner wall of the top of the cup cover, a reset spring is provided between the scissors located at the same height section of the abutment sleeve, and the reset spring runs through the abutment sleeve.

[0009] Furthermore, a fixing plate is provided on the side of the outer wall of the rotating rod close to the abutting sleeve, and an auxiliary fixing plate is provided on the side of the outer wall of the rotating rod close to the rotating block. The diameters of the fixing plate and the auxiliary fixing plate are the same as the inner wall diameter of the cup body. A cross slot is provided on the side of the rotating block away from the rotating rod. The cross slot and the cross block have the same shape, and the positions of the scissors and the give-way grooves are aligned with each other.

[0010] Furthermore, the material of the scissors is ABS resin-like material, and the entire device is made of insulating and non-conductive materials.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By utilizing the raised cross-shaped structure of the cup cover and the recessed cross-shaped structure of the rotating block, multiple scissor cups can be extended to an appropriate length, making it convenient for fire rescue personnel to work at high positions. The scissors are made of ABS-like resin materials, which are insulated and non-conductive, and have good strength. The scissors achieve the shearing operation by means of the up and down movement of the rotating rod. The rotating rod in the cup body is connected and fixed to the cup rotating block. The rotating block is rotated manually to drive the rotating rod to achieve the up and down movement of the rotating rod, thereby driving the scissors to close and open.
