Description
One, technical field
The utility model relates to spanner, particularly a kind of movable eave tile spanner.
Two, background technology
In the maintenance process of centrifugal pump, often need the back of the body cap and the axle sleeve of fixed disassembly axle.Existing a kind of eave tile spanner is a stationary structure, and it exists following shortcoming or deficiency: 1. can only be at back of the body cap and the axle sleeve of dismounting with a kind of pump.2. because the on-the-spot centrifugal pump that uses is varied, existing spanner can not adapt to existing maintenance, need the multiple dismantling device of preparation, when existing eave tile spanner is not used, just use screwdriver, flat chisel and hammer match and carry out dismounting, so often cause back of the body cap and axle sleeve damage, scrap.3. because not matching of instrument also can cause operating personnel's damage, there is hidden danger.
Three, summary of the invention
The purpose of this utility model provides a kind of movable eave tile spanner, the movable structure that adopts screw mandrel to match with nut, both can overcome or avoid the shortcoming or the deficiency that exist in the above-mentioned prior art, can finish the dismounting task of various model centrifugal pumps back of the body caps and axle sleeve again quickly and safely.
Movable eave tile spanner described in the utility model comprises support, screw mandrel, nut, tapered end nail and handle.Described tapered end nail is installed on the other end of support, and nut is installed on the other end of support, and an end of screw mandrel matches with nut, and the other end of screw mandrel is equipped with handle.
Wherein, described screw mandrel and nut are box and pin engagement, and turning handle can be adjusted the distance of screw mandrel top and tapered end screw top end exactly.
The utility model has following advantage compared with prior art:
1, wide adaptability can be used for the dismounting operation that is equipped with cap and axle sleeve of various models;
2, owing to adopt movable structure, so operate supporting, flexible, dismounting speed is fast, efficient is high;
3, easy to operate, safety.
Four, description of drawings
Accompanying drawing is a kind of example structure schematic diagram of the present utility model
Five, the specific embodiment:
Consult accompanying drawing, a kind of movable eave tile spanner comprises support, screw mandrel, nut, tapered end nail and handle.Tapered end nail 2 is installed on an end of support 5, and nut 3 is installed on the other end of support 5, and an end of screw mandrel 4 matches with nut 3, and the other end of screw mandrel 4 is equipped with handle 1.
Screw mandrel 4 is the box and pin engagement with nut 3, and turning handle 1 can be adjusted the distance that screw mandrel 4 tops and tapered end are followed closely 2 tops exactly.
Claims (2)
