Problems solved by technology

At present, there is no uniform standard for the crank handles in the substation. Because different manufacturers and different types of equipment require inconsistent crank handles, some equipment has different requirements for the depth of the female crank handle and the length requirements for the referendum crank handle. Carrying multiple cranks at the same time, due to the large size and heavy weight of the cranks, brings a lot of physical burden to the staff, and often there is a phenomenon of carrying the wrong cranks, which leads to delays in work progress

Embodiment Construction

[0022] The present invention will be further explained below in conjunction with the drawings:

[0023] Such as Figure 1-9 As shown, the adjustable crank of this embodiment includes a handle part 1 and a handle head 2. The head 2 includes a sleeve 21 and a handle core 22 installed in the sleeve 21 and slidingly fitted with the sleeve 21, Match the shape of the core 22 with the shape of the opening inside the sleeve 21. In this embodiment, the core 22 is rectangular, such as Figure 5 As shown, an adjustment handle 23 is provided on the handle core 22, and an adjustment hole 211 that cooperates with the adjustment handle 23 to adjust the length of the core 22 is provided on the sleeve 21 and a fixing member for fixing the displacement position of the adjustment handle 23. The fixing member can be a buckle or a baffle that can fix the adjusting handle 23 on the sleeve. In this embodiment, the fixing member is composed of a plurality of grooves sequentially arranged along the axial...

Abstract

The invention relates to an adjustable crank handle. The adjustable crank handle comprises a handle part and a handle head part, wherein the handle part comprises a sleeve and a handle core which is mounted in the sleeve and is matched with the sleeve in a sliding manner; the shape of the handle core is matched with the shape of a hole formed in sleeve; an adjustable handle is arranged on the handle core; and the sleeve is provided with an adjusting hole which is matched with the adjustable handle and is used for adjusting length of the handle core, and a fixing part for fixing a displacement position of the adjustable handle. According to the adjustable crank handle provided by the invention, the depth and length of the crank handle can be adjusted through the adjustable handle, so that the crank handle can be suitable for almost equipment including a handcart switch, a hand-operated disconnecting link and the like; and a condition that a plurality of crank handles need to be carried in a working process is avoided, and the weight and size of tools needing to be carried can be greatly reduced.

Description

Technical field [0001] The invention relates to a crank, in particular to an adjustable crank. Background technique [0002] Crank handles are mainly used for handcart switches and hand-cranked guillotines in substations, and can also be used in other industries such as machine tools and hand-cranked diesel engines. At present, there is no unified standard for cradle handles in substations. Because different manufacturers and different types of equipment require different cradles, some equipment has different requirements for the depth of the female cradle and the length of the referendum cradle. Carrying multiple cradles at the same time, due to the large size and heavy weight of the cradles, brings a great physical burden to the staff, and the phenomenon of wearing the wrong cradles often occurs, resulting in delays in work progress. Summary of the invention [0003] The purpose of the present invention is to provide an adjustable crank, which is suitable for most handcart swit...
