Abstract
The utility model relates to a one-way ratchet wrench which comprises a handle, a ratchet wheel and a double-sided toothed claw. The one-way ratchet wrench is particularly suitable for various handwheel valves, and the utility model has the advantages of simple appearance and structure and convenient operation. Workmen's labor strength can be reduced, and the damage of the handwheel valve can be reduced.
Description
The utility model is a kind of hand tools, the spanner of the various handwheel type of especially a kind of suitable locomotive valve class.
At present, on the rail traction equipment dong feng 4 locomotive the various valves of One's name is legion are arranged, they are respectively applied in each piping of locomotive Oil, Water, Gas and play blocking-up, open or corrective action, and these valve-operating stud great majority are the handwheel type, promptly with the open and close or the adjustment that turn handwheel mode control valve.This handwheel external form sub-circular directly through mostly being 50-90mm, is required great effort when twisting valve, when the installation of valve is comparatively hidden, the open and close of valve, adjustment be difficulty, and locomotive personnel cautious hammer commonly used, adjustable wrench, weight etc. knock handwheel easily to be made it to damage, and valve can not open and close or adjustment.Yet do not find the ratchet spanner of adjusting handle valve.
The purpose of this utility model is to provide a kind of ratchet spanner of suitable adjusting handle valve, and the valve that solves fully with handwheel open and close or adjustment uses bad situation, alleviates working strength of workers.
For achieving the above object, the utility model has adopted following manner: this spanner is by single direction ratchet, two-sided hock, and the handle that is fit to length is formed, and hock body and ratchet core are connected as one, and handle and ratchet shell are connected as a single entity.During use, entangle the spoke rib of wheel valve with hock wherein, moving handle can tight or loose valve, and hock is circular-arc to guarantee blocking handwheel spoke rib, outer scurrying when stressed.In the time of need oppositely turning handwheel, after only needing spanner turned over turnback, hock is inserted in handwheel and moves handle get final product.
Advantage of the present utility model is: simple in structure, easy to use, greatly reduced working strength of workers.
Below in conjunction with description of drawings structure of the present utility model and operation principle:
Fig. 1 is a front view of the present utility model
Fig. 2 is a left view of the present utility model.
As shown in Figure 1: the utility model is made up of two-sided hock 1, ratchet 2, handle 3, and handle 3 is connected as a single entity with the shell of ratchet 2.Appropriate length is adopted in the position of the wheel valve that handle can be regulated according to need.
As shown in Figure 2: two-sided hock 1 is connected as a single entity with the core of ratchet 2, and the external form of hock is curved.The quantity of the tooth of hock is generally more than 3, preferably selects 6 for use, and the size of two sides hock tooth, and the quantity of tooth is identical.During actual the use, be inserted in handwheel spoke rib with hock 1 wherein, moving handle can tight or loose valve, and when needing counter motion, counter-rotating spanner 180 is spent, and is inserted in handwheel spoke rib with the another side hock, moves handle and can realize counter motion.
Certainly, for increasing the function of this device, the convenient use also can be installed inner chamber at the afterbody of handle additional and be square or hexagonal bolt.
