Abstract
The utility model discloses a small-sized door opener. A supporting head which is downwards connected with an oil cylinder is arranged at the upper part of the small-sized door opener, a piston rod is arranged inside the oil cylinder, the bottom of the oil cylinder is connected with a large-bottom foot, the bottom of the piston rod is connected with a small-bottom foot through a tension spring, and one side of the supporting head is connected with an opener connector component which is communicated with the oil cylinder. The door opener disclosed by the utility model has the effects that the opener facilitates rescue implementation in a narrow and small space, can be applied to lifting, supporting, and automatic resetting, and is small in size, light in weight, and simple and convenient in parts assembly.
Description
Technical field
The utility model belongs to, particularly a kind of small-sized door opener.Hydraulic relief break-in tool part is applicable to car accident scene, sealed building opening of doors and windows, support.
Background technology
Existing similar products volume is large, quality heavy, takies very large space during rescue, and very large limitation is arranged.And device travel is little, and range of application is little
The utility model content
Technical problem to be solved in the utility model is: a kind of small-sized door opener is provided.It is little, lightweight to reach volume; Assembly of the parts is simple and convenient.Be convenient to small space and implement rescue; But but the lifting support automatically resets.
The technical solution of the utility model is:
A kind of small-sized door opener is characterized in that: small-sized door opener top is supporting member, and supporting member connects oil cylinder downwards, and piston rod is housed in the oil cylinder, and the oil cylinder bottom connects large footing, and the piston rod bottom connects little footing by extension spring; Support first side and connect door opener adapter assembly, adapter assembly and oil cylinder UNICOM.
The utility model effect is:
Be convenient to small space and implement rescue; But but the lifting support automatically resets; Volume is little, lightweight; Assembly of the parts is simple and convenient.
Accurate Calculation hydraulic cylinder cylinder diameter and wall thickness are selected the alloy in lightweight material, reach the little design objective of lightweight volume; Big or small footing (opening the lifting part), cooperation supporting member (support part) according to ergonomic design; Supporting member, big or small footing adopt precision castings to reduce processing capacity.
Technical indicator: draw in the height 270mm, the support stroke is greater than 150mm, and support power is greater than 60kN, and weight is less than 5.5kg.
Description of drawings
Fig. 1 is small-sized door opener structure chart.
The 1-supporting member; The 2-oil cylinder; The 3-piston rod; The 4-extension spring; The 5-oil sealing; The large footing of 6-; The little footing of 7-; 8-door opener adapter assembly.
The specific embodiment
A kind of small-sized door opener as shown in the figure, small-sized door opener top is supporting member, and supporting member connects oil cylinder downwards, and piston rod is housed in the oil cylinder, and the oil cylinder bottom connects large footing, and the piston rod bottom connects little footing by extension spring; Support first side and connect door opener adapter assembly, adapter assembly and oil cylinder UNICOM.
Use hydraulic pump to door opener adapter assembly (8) fuel feeding, door opener is pushing piston bar (3) under the effect of hydraulic oil, and the little footing of piston rod (3) interlock (7) stretches out, and realizes little footing and large footing (6) unlatching with this, lifting and supported head reach the function of support.
