Abstract

The invention discloses an operating rod convenient and fast to use and for a valve well. The operating rod comprises a connecting rod. A moving plate is arranged in an inner cavity of the connectingrod. Clamping plates are arranged on the two sides of the moving plate in a sleeving mode, sliding wheels are arranged in inner cavities of the clamping plates in a sleeved mode, and the surfaces of the sliding wheels are movably connected with the clamping plates through rotating shafts. Sliding grooves which are matched with the sliding wheels are formed in the two sides of the inner cavity of the connecting rod. Springs are arranged on the portions, connected with the connecting rod, of the two sides of the top of the moving plate. A movable base is fixedly connected with the center of thetop of the moving plate. A threaded rod is movably connected with an inner cavity of the movable base, and the top of the threaded rod penetrates through the connecting rod and extends to the top of the connecting rod. According to the operating rod convenient and fast to use and for the valve well, due to the mutual cooperation of the connecting rod, a limiting shaft, the threaded rod, a handle,the springs, the sliding grooves, the movable base, an operation rod, the moving plate, the clamping plates, the sliding wheels and the rotating shafts, the length of the operating rod can be adjustedwhen the operating rod is used.

Description

technical field [0001] The invention relates to the technical field of a convenient operating lever for a valve well, in particular to a convenient operating lever for a valve well. Background technique [0002] The valve well is a valve for underground pipelines and underground pipelines (such as tap water, oil, natural gas pipelines, etc.) In order to facilitate the opening and closing of some pipeline network operations or maintenance operations, a pit (or well) similar to a small room is set. Arrange valves and other installations in this pit, which is convenient for regular inspection, cleaning and dredging of pipelines, and prevents the hub of pipeline blockage. This pit is called the valve well. If there are valve wells, there must be valves, but if there are valves, there must not be valve wells. [0003] When the staff operates the inside of the valve well, they need to use the operating rod to operate. However, when the existing operating rods on the market are i...
