Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, a miniature hydraulic expander is composed of an oil cylinder 1, a quick joint 2, a wedge 3 and two expansion arms 4 on the left and right. The oil cylinder 1 is connected to the power source through the quick joint 2, and the end of the piston 8 is connected to the wedge 3. The left and right expansion arms 4 are respectively connected to the surface of the oil cylinder 1 through a rotating shaft 6. The oil cylinder 1 is a single-acting oil cylinder and resets through the built-in return spring 9. The left and right expansion arms 4 adopt a thin duck mouth structure, and the left and right expansion arms 4 Expansion arm return springs 5 ​​are arranged between them, and some anti-slip teeth 7 are respectively arranged on the outer surfaces of the ends of the two expansion arms 4 on the left and right.

[0014] When the equipment of the present invention is used, after the quick-change joint is connected to the oil pipe, the pist...

Abstract

A miniature hydraulic spreader consists of an oil cylinder, a quick connector, a wedge block and left and right spreading arms, wherein the oil cylinder is connected with a power source through the quick connector, the piston end of the oil cylinder is connected with the wedge block, the left and right spreading arms are connected with the surface of the oil cylinder through a rotary shaft, the oil cylinder is a single-acting oil cylinder and is reset through a built-in reset spring, the left and right spreading arms are of thin duck mouth structures, and a reset spring is arranged between theleft and right spreading arms. The miniature hydraulic spreader adopts the single-acting oil cylinder, does not need a reversing device and is simple in structure, small in size and suitable for rescue work in a narrow space. The spreading arms adopt the thin duck mouth design, and a wedging gap is smaller. The spreading arm reset spring is arranged between the two spreading arms, the spreading arms are automatically reset to a closing state, the resetting speed of a piston is improved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a fire rescue tool, in particular to a miniature hydraulic expander. Background technique [0002] The demolition expander is a commonly used equipment for firefighters to forcibly open doors and windows, demolish buildings, open fire exits, clear smoldering embers and clean up fire sites when extinguishing fires or saving people. Existing demolition and expansion tools are mainly manually operated fire axes, fire hooks, iron collars and insulating shears. These tools are time-consuming and laborious to use, and the demolition efficiency is low, which affects the fire rescue efficiency. Contents of the invention [0003] The invention provides a miniature hydraulic expander to solve the problem in the prior art that the operation of a manual rescue expansion tool is time-consuming and labor-intensive and affects rescue efficiency. [0004] The technical solution adopted by the present invention to solve its technical problem...
