Abstract
The present invention relates to a kind of pawl lockers for ratchet spanner, it is made of fixing sleeve and pawl, fixation is set on the driving end of ratchet spanner, three pawls are along the circumferential direction uniformly arranged on the side wall of fixing sleeve, each pawl is that one be made of baffle and tabletting is similar to L-shaped structure, three mounting grooves are uniformly produced on fixing sleeve, hinge fills a pawl in each mounting groove, the baffle of pawl and the junction of tabletting and fixing sleeve hinge fill, baffle is located on the inside of fixing sleeve, and tabletting is located on the outside of fixing sleeve.The present invention efficiently solves the blocked up production problem for causing operating personnel to handle small part inconvenience of Working gloves, greatly facilitate the work of staff, it solves the operational inconvenient biggish security risk with existing for generated because dressing safety protective tools, is suitble to promote and apply.
Description
Technical field
The present invention relates to livewire work professional skill field, especially a kind of pawl locker for ratchet spanner.
Background technique
In current livewire work work, be frequently necessary in operation process equipment that nutting fastening is newly replaced or
Remove used equipment.But in operation, because operating personnel needs to dress mitten, insulating glove and kid gloves (altogether
Count three layers of gloves) as safety device, this results in the operating flexibility of the hand of operating personnel to substantially reduce, and easily occurs because taking
Pinch incessantly and caused by falling object from high altitude violation phenomenon, cause very big hidden danger to safety in production.
Summary of the invention
It is a kind of easy to use it is an object of the invention to provide in place of making up the deficiencies in the prior art, it can be avoided
Falling object from high altitude phenomenon and the high pawl locker for ratchet spanner of safety and reliability.
The purpose of the present invention is what is realized by following technological means:
A kind of pawl locker for ratchet spanner, it is characterised in that: the pawl locker is by fixing sleeve and spine
Pawl is constituted, and fixation is set on the driving end of ratchet spanner, and three spine are along the circumferential direction uniformly arranged on the side wall of fixing sleeve
Pawl, each pawl are that one be made of baffle and tabletting is similar to L-shaped structure, and three installations are uniformly produced on fixing sleeve
Slot, hinge fills a pawl, the baffle of pawl and the junction of tabletting in each mounting groove and fixing sleeve hinge fills, and baffle is located at solid
Fixed set inside, tabletting are located on the outside of fixing sleeve.
Moreover, the fixing sleeve and driving end are coaxially disposed.
The advantages and positive effects of the present invention are:
The present invention be it is a kind of design reasonable, easy to operate, manufacturing cost is low, high safety and reliability, be suitble to promote and apply
For the pawl locker of ratchet spanner, the present apparatus is mounted on ratchet spanner to can solve staff's wearing at this stage exhausted
In the case where edge gloves and kid gloves, it is affectedly bashful nut, spring ring and the very inconvenient problem of washer.
Detailed description of the invention
Fig. 1 is main view of the invention；
Fig. 2 is the assembling schematic diagram (broken section) of the present invention with ratchet spanner.
Specific embodiment
Describe the embodiment of the present invention in detail with reference to the accompanying drawing；It should be noted that the present embodiment be it is narrative, no
It is restrictive, this does not limit the scope of protection of the present invention.
A kind of pawl locker for ratchet spanner, the pawl locker are made of fixing sleeve 2 and pawl 1, Gu
Fixed set is co-axially located on the driving end 3 of ratchet spanner 7, is along the circumferential direction uniformly arranged multiple ratchets on the side wall of fixing sleeve.
The pawl described in the present embodiment is three, and it is L-shaped that each pawl is that one be made of baffle 5 and tabletting 4 is similar to
Structure uniformly produces three mounting grooves 6 on fixing sleeve, and hinge fills a pawl, the baffle of pawl and tabletting in each mounting groove
Junction and fixing sleeve hinge fill, baffle is located on the inside of fixing sleeve, and tabletting is located at fixing sleeve outside.
The present invention uses pawl lock in ratchet wrench head as the ratchet wrench head of core, pawl can be utilized effective
Nut, washer and spring pad disposable lock are buckled it is solid, solve operator dress insulating protection apparatus cause it is inconvenient
The problem of, the violation phenomenon for easily occurring falling object from high altitude caused by due to being affectedly bashful incessantly before this is avoided, security risk is eliminated,
And working efficiency can also be improved.
The operation principle of the present invention is that:
Using lever principle, end moment of shaking hands is far longer than spanner head end, when operating staff without lifting an eyebrow.Spanner
The pawl lock of end can be very good to latch in nut, washer and spring pad in spanner, and it is exhausted to solve operator's wearing
Edge safety device leads to inconvenient problem, avoids and easily occurs disobeying for falling object from high altitude caused by due to being affectedly bashful incessantly before this
Zhang Xianxiang.
Application method of the invention are as follows:
Before tightening nut, nut, spring ring, washer can be sequentially placed into spanner end, by the function of locker
Components can effectively be lockked, be directly screwed on corresponding screw；After unscrewing nut, the latching function for also relying on pawl makes
Nut, spring ring, washer will not fall off, and solve the security risk of falling object from high altitude.
