Abstract
The utility model relates to a large-torque socket wrench. An internal rotation base is connected with an outer sleeve base into integration through a block medium element, and the mutual loosing or sliding between the internal rotation base and the outer sleeve base is prevented via the block medium element. Simultaneously, a bearing hole is arranged on the top hoop of the internal rotation base and used for enchasing a spring steel ball to make the steel ball arranged on one of two inlay arcs of the inner part of an upper sleeve body to select the direction of force application of the outside. The utility model has the advantages of simple and reasonable structure, easy manufacture, convenient use, no noise, no specific gap displacement, large transfer moment and high elasticity, and is suitable for being matched with the existing various socket wrenches.
Description
The utility model relates to a kind of box spanner, and refering in particular to is a kind of high pulling torque box spanner.
Traditional box spanner made from click apparatus, though have simple in structure, convenient processing and manufacture, advantages such as low torque condition result of use is better, but because due to its structure, in use exist the some shortcomings part, not high as cause spanner in use can not bear bigger torsion or intensity because of click intensity is lower, or because of being subjected to click backlash size restrictions, be awkward when causing spanner to be in some angle, and the utilization rate of box spanner in life is quite high, therefore, brings some inconvenience for people's use.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of rational in infrastructure, and processing and manufacturing is easy, high pulling torque box spanner easy to use.
The utility model is to adopt following proposal to realize: it is connected as a single entity by resistance Jie element by an inward turning seat and an outer casing seat, and by this resistance Jie element block inward turning seat and outer casing seat mutually pine please or slide so that spanner is not subjected to angle limits when having high strength, high torsion and operation; Simultaneously, on the apical ring of inward turning seat, be provided with one and hold the hole and can steel ball one of be supported in two embedding arcs of upper sleeve body inside, the direction of extraneous application of force when selective inward turning seat, the two turn of outer casing seat.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:

See accompanying drawing 1,2,3, the utility model is by inward turning seat (1), resistance Jie's element (2), bezel ring, (3), outer casing seat (4) is formed, the pedestal surface of described inward turning seat (1) is become by some equidistant side cuts (11) composite rim, the top then is the less apical ring of a diameter (12), apical ring (12) one sides then are equipped with can be for the lug (13) of handle pivot joint, the ring side face of apical ring (12) is provided with one and can supplies setting-in spring (15) in addition, steel ball (16) hold hole (14), resistance Jie's element (2) comprises one by two halves picture (21a), (the 21b)) upper sleeve body of Zu Chenging (21) and being installed on the inward turning seat (1), and a side of upper sleeve body (21) is extended with some equidistant corner posts (211), its skin is arranged with reed (22), then be situated between between each reed (22) and be equipped with roller (23), the inner wall of ring body of upper sleeve body (2) is provided with the two embedding arcs (212) that can supply steel ball (16) butted, (213), and upper sleeve body (21) outer surface is provided with a circular groove (214) that supplies a fastener (215) to be embedded, bezel ring, (3) is sleeved on the upper cover body (21), its ring wall is provided with one and can supplies latch (32) to insert the perforation (31) that articulates the perforation (216) on the upper sleeve body (21) admittedly, establish First Five-Year Plan annular groove (41) on the ring in the outer casing seat (4) and be sleeved on that upper sleeve body (21) is gone up and by fastener (215) snaps into position, outer casing seat (4) lower end extends one for the projection (42) that articulates sleeve.
See accompanying drawing 4,5, another embodiment of the utility model is with handle and the synthetic toggle (30) of outer casing seat (4), and makes the turn-knob (101) of the top end face formation one control turn application of force direction of inward turning seat (1).
See accompanying drawing 6,7, another embodiment of the utility model is provided with the top of inward turning seat (1) to be single lug (17) or recessed slot (18), so that articulate with handle.
See accompanying drawing 8,9,10, the further improvement of the utility model resistance Jie's element (21) is to make the corner post of upper sleeve body (21 ') (211 ') be the slotting solid combination of separate type, and reed then is provided with elastic gel (the 22 ') replacement of the arcuation of the through hole of planting for corner post (211 ') (221 ') with nearly centre.
See accompanying drawing 3, using method of the present utility model and operation principle are sketched in following: when spanner need be made the clockwise direction rotation application of force, make the steel ball (16) in it butted in embedding arc (213) upper sleeve body (21) rotation counterclockwise earlier, each roller this moment (23) will be resisted against the A end in equidistant side cut (11) and the interior garden of outer casing seat (4) slit between week on the inward turning seat (1), both are combined as a whole and make inward turning seat (1) and outer casing seat (4), can't produce relative slip, thereby outer casing seat (4) is rotated by application of force direction clockwise direction interlock with inward turning seat (1); Reach the purpose that moment is transmitted, in the time will making spanner counterclockwise do the return displacement, each roller (23) will be entered the B point in slit by the A end, and reed (22) is compressed, at this moment, inward turning seat (1) is separated with outer casing seat (4), and inward turning seat (1) counterclockwise rotation whole with the location of resistance Jie's element (2) invar pearl (16), drive outer cover for seat (4) and the synchronous function of rotating of inward turning seat (1) thereby lose, that is during reverse stroke, spanner forms idle running, and return rotation noiseless, do not have the displacement of specific gap, thereby be different from traditional pawl ratchet formula box spanner.
In sum, the utility model is simple and reasonable, and processing and manufacturing is easy, and is easy to use, and noiseless does not have the displacement of specific gap, and carry-over moment is big, bullet degree height, and wide accommodation is suitable for and the existing supporting use of all kinds of box spanners.
