Description
Technical field
The utility model belongs to lifesaving appliance technical field, is specifically related to one and speedily carries out rescue work lifesaving expander.
Background technology
Expander, is also stretching pliers, is mainly used in the rescue and relief work use when situation such as traffic accident, natural calamity occurs, can be realized the operations such as expansion, support, thus save out by victim from constrained environment by expander.Structure that what existing expander adopted is is mainly by two triangle binding clips, and binding clip two outer end is articulated and connected, and pars intermedia drives leg-of-mutton binding clip to open by a hydraulic cylinder colleague or closed.But this binding clip is owing to being subject to structure restriction, and expandable angle is little, and the ultimate range that can expand is also very little; In some occasion, also need first first to expand with expander, and then expand distance by devices such as push rods, therefore operate and extremely bother.
Utility model content
The purpose of this utility model is: the problem that existing expander expansion distance is less, provides one to speedily carry out rescue work lifesaving expander, and distensible distance is larger, without the need to coordinating push rod to use, simple to operate, facilitates, lightweight.
To achieve these goals, the technical solution adopted in the utility model is:
One is speedily carried out rescue work lifesaving expander, comprise supporting seat and a pair stretching pliers assembly, stretching pliers assembly comprises stretching pliers body and dynamical element, stretching pliers body comprises tong arm portion and is positioned at the clamp head part of one end, tong arm portion, stretching pliers body is articulated and connected by the tong arm portion other end and supporting seat, one end and the stretching pliers body of dynamical element are articulated and connected, and the other end and supporting seat are articulated and connected; A pair described stretching pliers assembly rotates around pin joint respectively by dynamical element driving expansion body, realizes opening or closing, and time closed, two clamp head parts merging form pointed shape structure.
Preferably, the tong arm portion of described stretching pliers body adopts Telescopic adjustable structure.
Preferably, described dynamical element adopts hydraulic cylinder or cylinder, and cylinder body portion and supporting seat are articulated and connected, and cylinder bar portion and stretching pliers body are articulated and connected.
Preferably, described clamp head part adopts triangular structure of right angle, and two clamp head parts are oppositely arranged, and when a pair stretching pliers assembly closes, are fitted by right-angle side, the pointed shape structure described in formation; Tong arm portion is arranged on the hypotenuse extended line of clamp head part, and the right angle of dynamical element and clamp head part is articulated and connected.
Preferably, described clamp head part outer ledge is arranged to laciniation.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
One of the present utility model is speedily carried out rescue work lifesaving expander, by being provided with the stretching pliers assembly of stretching pliers body and dynamical element composition, stretching pliers body arranges tong arm portion, make the expansible distance of stretching pliers body larger, maximum extension distance generally can reach 2 meters, stretching pliers body is directly driven by independent dynamical element, and expansionary force is larger; Do not need to coordinate push rod to use, simple to operate, convenient;
Simultaneously two clamp head parts adopt the mode of right-angle sides laminating, and laminating degree is better, and therefore expander can also use as clamper, make expander have expansion and clamp multi-functional.

Fig. 2 is expander open configuration front view of the present utility model.
Mark in figure: 100-supporting seat, 200-stretching pliers assembly, 210-stretching pliers body, 211-tong arm portion, 212-clamp head part, 220-dynamical element.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, one of the present utility model is speedily carried out rescue work lifesaving expander, comprise supporting seat 100 and a pair stretching pliers assembly 200, stretching pliers assembly 200 comprises stretching pliers body 210 and dynamical element 220, stretching pliers body 210 comprises tong arm portion 211 and is positioned at the clamp head part 212 of one end, tong arm portion 211, stretching pliers body 210 is articulated and connected by tong arm portion 211 other end and supporting seat 100, one end and the stretching pliers body 210 of dynamical element 220 are articulated and connected, and the other end and supporting seat 100 are articulated and connected; A pair described stretching pliers assembly 200 drives expansion body to rotate around pin joint respectively by dynamical element 220, realization is opened or is closed, and time closed, two clamp head parts 212 merge formation pointed shape structures, by this pointed shape structure, just can easily be inserted in the gap needing expansion.
Clamp head part 212 adopts triangular structure of right angle, and two clamp head parts 212 are oppositely arranged, and when a pair stretching pliers assembly 200 closes, is fitted by right-angle side, forms pointed shape structure; Tong arm portion 211 is arranged on the hypotenuse extended line of clamp head part 212, and dynamical element 220 is articulated and connected with the right angle of clamp head part 212.
In order to the distance of the expansible angle and expansion that make expander is larger, the tong arm portion 211 of stretching pliers body 210 adopts Telescopic adjustable structure, namely flexible nested structure is adopted, when needing the length regulating tong arm portion 211, unclamp fastening bolt, tong arm portion 211 is elongated or shortened, and then fixes fastening bolt, namely realize the length adjustment to tong arm portion 211.When reality uses, the length in tong arm portion 211 can be regulated according to actual conditions, to reach best expansible angle and expansible distance.
Dynamical element 220 adopts hydraulic cylinder or cylinder, and cylinder body portion and supporting seat 100 are articulated and connected, and cylinder bar portion and stretching pliers body 210 are articulated and connected.
Clamp head part 212 outer ledge is arranged to laciniation, to reach better skidproof effect.
Expander of the present utility model, during use, is driven dynamical element 220 to stretch by the power such as hydraulic pressure or air pressure, is rotated, thus realize expansion by the flexible stretching pliers body 210 that drives of dynamical element 220 around the pin joint in tong arm portion 211.Each parts of expander adopt light-weight high-strength material to make, and during use, lighter in weight, cheaply operates.
Simultaneously, the mode that two clamp head parts 212 adopt right-angle side to fit, laminating degree is better, therefore expander can also use as clamper, when needs gripping objects, first stretching pliers body 210 is opened, then shunk by dynamical element 220 and stretching pliers body 210 is closed, thus clamped by object, thus realize the holding function of expander.
