Abstract
The utility model relates to an easily assembled ratchet spanner. A ratchet with straight teeth and a ratchet block are arranged in a ratchet hole of a spanner and an open arc-shaped counterbore. One omega-shaped leaf spring is arranged in a small circular slot of the arc-shaped counterbore and an arc-shaped slot of the ratchet block for pushing the small circular slot and the arc-shaped slot to be engaged with each other. The utility model avoids the defects that because of the complicated structure of the existing spanner, the space of the existing spanner is small, and the assembly of the existing spanner is difficult. The utility model has the advantages of labor saving for assembly, time saving for time saving, fast assembly, convenient assembly, simple structure, and easy production and manufacture.
Description
A kind of easy assembling ratchet spanner, it relates to the ratchet spanner combination, and particularly the ratchet wheel block groove is the ratchet spanner of unenclosed construction.
The structure of tradition ratchet spanner, it is crescent blind hole that inwardly concaves of system in the ratchet hole of ratchet spanner main body, in the ratchet hole, adorn an external surface and be the middle hyperboloid shape ratchet that inwardly concaves, a two-sided projection is housed in the crescent blind hole, and the volt end face has the ratchet wheel block that can be inserted in spring pushing and pressing and ratchet engaged, as shown in Figure 4, but the ratchet of this structure and ratchet wheel block project organization complexity, make difficulty, because adapted space is little, the assembling difficulty.And at practical medi-spring fatiguability, when ratchet and ratchet wheel block meshed when dark, spring easily produces the escape phenomenon.
The purpose of this utility model provides and a kind of ratchet is cooperated by the curved surface tooth with ratchet wheel block changes the straight-tooth cooperation into, changes the crescent blind hole into the open state counterbore, overcomes existing ratchet spanner, and the project organization complexity is made difficulty, not easy-to-assemble weak point.
The utility model realizes in the following way, in the ratchet hole and little spring groove of wrench body, adorns an arc inboard and has the ratchet wheel block that tooth outside band deep-slotted chip breaker, top have little garden groove.Card is put a Ω shape sheet spring that plays the pushing and pressing effect in the little garden groove of ratchet wheel block and the spring groove in the arc counterbore.
The advantage that the utlity model has is the labyrinth that its simplifies and improved ratchet, ratchet wheel block, blind hole shape arc counterbore.Provide convenience for producing, making.It utilizes Ω shape sheet spring pushing and pressing ratchet wheel block and ratchet one-way joggleword stably, and particularly gram has limit original need to be nested with the difficult problem of assembling in minimum position, need only put part in uncovered counterbore now and can finish assembly working quickly and easily.
Description of drawings:
Accompanying drawing 1, the utility model shaft side decomposition figure
Accompanying drawing 2, the utility model partial sectional view
Accompanying drawing 3, the utility model broken section enlarged drawing
Accompanying drawing 4, existing ratchet spanner axonometric exploded view
In conjunction with the accompanying drawings a kind of easy assembling ratchet spanner of the utility model is described in further detail below by embodiment: it is by wrench body, split circlip, compositions such as cover plate, in attached Fig. 1 and 2, close uncovered arc counterbore 12 of spanner bandle place system in ratchet 11 holes of the band platform of wrench body 10 and split ring groove, about 1/4th places are shaped on the spring groove 13 that can snap in Ω shape sheet spring in arc length, adorn in ratchet hole 11 that the garden circumference is a straight-tooth outside one, be shaped on a deep-slotted chip breaker 31 on the outer arcuate face, the top has to block in the little garden groove 13 puts a Ω shape sheet spring 40 that plays the pushing and pressing effect, one of buckle closure is by C shape elastic ring 50 on the garden platform of ratchet end face and wrench body 10, be embedded in the cover plate 60 in the annular groove, buckle closure is on the ratchet hole, and C shape elastic ring is stuck in the wrench opening C shape spring groove just.Its operation principle is: when ratchet clockwise rotates (referring to accompanying drawing 3), ratchet is taken to Ω shape sheet spring direction with ratchet wheel block, the deep-slotted chip breaker 32 of ratchet wheel block is pressed against on the sheet spring outer rim, make ratchet 20 and ratchet wheel block 30 be the maximal clearance state, spanner can rotate smoothly, can unscrew bolt or nut.When counter-rotation, ratchet 10 and ratchet wheel block 30 engagements also make ratchet wheel block move to front side, make it be tight against the side of arc counterbore 12 and prevent that ratchet from rotating, and can screw the bolt type nut.
