Abstract
The utility model belongs to the technical field of locomotive maintenance, and provides an annular wrench (1) for locomotive rearview mirror cylinder maintenance; one end of the ring spanner (1) is an arc-shaped plate, a plurality of clamping grooves (2) matched with the piston rod (3) required to be loosened in shape are formed in the inner wall of the arc-shaped plate, and the clamping grooves are identical in shape and size. The utility model provides a ring spanner for locomotive rearview mirror cylinder overhauls, a plurality of draw-in grooves that have can make ring spanner can both become flexible piston rod in any position, do not receive the restriction of mounting panel and support, have saved maintenance time, have improved work efficiency to have simple structure, convenient and practical's characteristics.
Description
Technical field
The utility model belongs to the locomotive inspection and repair technical field, relates generally to a kind of ring spanner that is used for the maintenance of rearview mirror of motorcycle cylinder.
Background technology
Because piston rod and perimeter frame close in the assembling of rearview mirror cylinder; When needing to change cylinder in the maintenance; Need first loose-lifting piston bar; Be to adopt each clamping piston bar of nipper plier to move during the loose-lifting piston bar in the prior art, promptly waste time and energy, cause piston rod to scrap thereby be prone to form the piston rod catcher mark again.
Summary of the invention
For solving the problems of the technologies described above, the purpose of the utility model is to propose a kind of ring spanner that is used for the maintenance of rearview mirror of motorcycle cylinder, makes it can save the repair time, increase work efficiency, and has simple in structure, convenient and practical characteristics.
Adopt following technical scheme for accomplishing foregoing invention task the utility model:
A kind of ring spanner that is used for the maintenance of rearview mirror of motorcycle cylinder, an end of described ring spanner is an arc, has the draw-in groove that a plurality of and required loose-lifting piston rod-shape kissing is joined on the inwall of said arc, the shape of a plurality of draw-in grooves, measure-alike.
A kind of ring spanner that is used for the maintenance of rearview mirror of motorcycle cylinder that the utility model proposes; The a plurality of draw-in grooves that had can make the ring spanner can both the loose-lifting piston bar in any position; Do not receive the restriction of installing plate and support; Save the repair time, improved operating efficiency, and had simple in structure, convenient and practical characteristics.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the user mode figure of the utility model.
Among the figure: 1, ring spanner, 2, draw-in groove, 3, piston rod, 4, installing plate.
The specific embodiment
The structure of the utility model is explained with the embodiment that provides in conjunction with accompanying drawing:
As shown in Figure 1; A kind of ring spanner that is used for the maintenance of rearview mirror of motorcycle cylinder; One end of the ring spanner 1 that is processed by steel plate is an arc, has the draw-in groove 2 that a plurality of and required loose-lifting piston rod-shape kissing is joined on the inwall of said arc, the shape of a plurality of draw-in grooves, measure-alike.Among this embodiment, have four shapes, measure-alike draw-in groove on the inwall of arc.
As shown in Figure 2, when needing the assembling of maintenance cylinder, with ring spanner 1 can be in any position seized piston bar 3, loose-lifting piston bar easily, locomotive under repairing rearview mirror.
