Abstract
The invention discloses a kind of ratchet spanner, including pulling body, gear ring and block, the front end pulling body is provided with installing hole, and gear ring is arranged in installing hole, and the outer circumference surface of gear ring has been wholely set the first ratchet, pull and body is provided with the inner chamber being connected with installing hole, block is arranged in the lumen, and block is wholely set the second ratchet being meshed with the first ratchet, is characterized as being to pull and internal is provided with inclined hole, being provided with spring in inclined hole, spring top is on the back bevel of block; Advantage is owing to being assemblied in the inclined hole pulling body by spring, and spring top is on the back bevel of block, greatly reduces the assembly difficulty of spring, improves production efficiency; Also make spring that the active force of block is stable simultaneously, it is ensured that when needing block to snap tight against with gear ring block be engaged with gear ring reliable and stable.
Description
Technical field
The present invention relates to a kind of spanner, particularly relate to a kind of one-way ratchet wrench.
Background technology
At present, ratchet spanner can be divided mainly into one-way ratchet wrench and reversible ratcheting tool two kinds, and have a kind of one-way ratchet wrench, it mainly includes gear ring, pull body, block and spring etc., gear ring is meshed with block, spring is arranged on the side of block, under the action of the spring, when pulling body and rotating to certain direction, spring withstands block, block and gear ring is made to snap tight against, thus driving gear ring to rotate together, in order to tighten or to unclamp nut, but current this one-way ratchet wrench, owing to spring is relatively fine, and its installation site is positioned at the side of block, cause that its assembling is extremely difficult, production efficiency is very low, and spring is after being subject to counteracting force, its bending direction is unrestricted, cause that it is unstable to the active force of block, thus easily there is gear ring skidding with gear ring when needs block snaps tight against.
Summary of the invention
The technical problem to be solved be to provide a kind of assemble simple, use reliable and stable one-way ratchet wrench.
This invention address that the technical scheme that above-mentioned technical problem adopts is: a kind of one-way ratchet wrench, including pulling body, gear ring and block, the described front end pulling body is provided with installing hole, described gear ring is arranged in described installing hole, the outer circumference surface of described gear ring has been wholely set the first ratchet, described pulling is provided with the inner chamber being connected with described installing hole on body, described block is arranged in described inner chamber, described block is wholely set the second ratchet being meshed with the first described ratchet, described pulling internal is provided with inclined hole, it is provided with spring in described inclined hole, described spring top is on the back bevel of described block.
In horizontal plane, the angle of the centrage of described inclined hole and the described centrage pulling body is 10��20 ��, the center of described gear ring is 3��15 �� to the angle of line and the described centrage pulling body of the central point of described inclined hole opening, and the angle of the centrage of described inclined hole and described block back bevel is 70��110 ��.
Being provided with spring catch in described inclined hole, described spring top is connected between described spring catch and described inclined hole, and described spring catch withstands on the back bevel of described block, and this structure makes spring that the active force of block is more reliable and more stable.
Being provided with spring eye in described spring catch, one end of described spring is inserted in described spring eye, and the other end of described spring withstands in described inclined hole.
Being wholely set gear step on the back bevel of described block, described gear step is positioned at the inner side of described spring catch, when can prevent spanner quick rotation, skids between block and spring catch, further ensures the reliable and stable of use.
The thickness of described gear step is more than 0.3mm.
Compared with prior art, it is an advantage of the invention that owing to spring is assemblied in the inclined hole pulling body, and spring top is on the back bevel of block, greatly reduces the assembly difficulty of spring, improves production efficiency; Also make spring that the active force of block is stable simultaneously, it is ensured that when needing block to snap tight against with gear ring block be engaged with gear ring reliable and stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the close-up schematic view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in the figure, a kind of one-way ratchet wrench, including pulling body 1, gear ring 2, block 3 and spring 5, the front end pulling body 1 is provided with installing hole (not marking in figure), gear ring 2 is arranged in installing hole, the outer circumference surface of gear ring 2 has been wholely set the first ratchet 21, pull and body 1 is provided with the inner chamber 11 being connected with installing hole, block 3 is arranged in inner chamber 11, block 3 is wholely set the second ratchet 31 being meshed with the first ratchet 21, pull and in body 1, be provided with inclined hole 12, spring catch 4 it is provided with in inclined hole 12, spring eye (not marking in figure) it is provided with in spring catch 4, one end of spring 5 is inserted in spring eye, the other end of spring 5 withstands in inclined hole 12, spring catch 4 withstands on the back bevel 32 of block 3, the back bevel of block 3 has been wholely set gear step 33, gear step 33 is positioned at the inner side of spring catch 4, in horizontal plane, the angle �� of the centrage of inclined hole 12 and the centrage pulling body 1 is 18 ��, the center of gear ring 2 is 10 �� to the angle �� of line and the centrage pulling body 1 of the central point of inclined hole 12 opening, the angle �� of the centrage of inclined hole 12 and block 3 back bevel 32 is 85 ��.
In above-described embodiment, can according to the size of spanner and being actually needed, the centrage of inclined hole 12 is selected in the scope of 10��20 �� with the angle �� of the centrage pulling body 1, the center of gear ring 2 is selected in the scope of 3��15 �� to the line of the central point of inclined hole 12 opening and the angle �� of the centrage pulling body 1, the centrage of inclined hole 12 and the angle �� of block 3 back bevel 32 are selected in the scope of 70��110 ��, and the thickness of gear step 33 is more than 0.3mm.
This one-way ratchet wrench realizes the process of one-directional rotation: as shown in the figure, gear ring 2 is enclosed within the nut needing to tighten or unclamp, when pulling body 1 and rotating counterclockwise, block 3 is driven to rotate counterclockwise, now, the spring catch 4 only small active force that even do not produce of active force to block 3, there is relative sliding between the second ratchet 31 on block 3 and the first ratchet 21 on gear ring 2, now, gear ring 2 is motionless; And when pulling body 1 and rotating clockwise, drive block 3 to rotate clockwise, now, block 3 is applied active force by spring catch 4, the second ratchet 31 on block 3 is made to be mutually twisted with the first ratchet 21 on gear ring 2, thus driving gear ring 2 to rotate clockwise together, by nut screwing clamping or unclamp.
