Abstract

The utility model provides a ratchet sleeve structure, mainly comprising a body, a connecting hole which is formed at an end of the body, a dozen against top convexities which are arranged along the inner edge circle of the connecting hole and the convexities are adjacent to each other at intervals by concaves. By the convexities, the utility model can lock special screw and screw cap of gear type, ratchet type and planet type as well as ecumenical screw and screw cap. In addition, since the convexities are adjacent to each other at intervals by concaves, the ratchet sleeve can lock a metric screw and an inch screw of similar types and the operation is convenient.

Description

The ratchet tube-in-tube structure

Affiliated field

The utility model is that it belongs to the instrument class about a kind of ratchet tube-in-tube structure, is specially adapted to screw and twists solid class instrument.

Technical background

General sleeve in the use, only can lock at common four jiaos, hexagonal and anistree screw, if when desiring lock gear type, ratchet type and star-like special screw, then need to use specific purpose tool in addition, can lock and dismantle to gear type, ratchet type and star-like special screw; And screw is now divided into metric system and two kinds of standard specifications made in Great Britain, the user can't lock and dismantle with the screw of same group of sleeve to two kinds of standard specifications, so, the user often need purchase the sleeve of two kinds of specifications to carry out operation, not only cause and use inconvenience, also be difficult for and purchase the too high problem of instrument cost because of too much sleeve causes to take in; Therefore, the inventor is for improving the defective of existing sleeve, design a kind of ratchet tube-in-tube structure, except the lock that can be used in gear type, ratchet type and star-like special screw is established and is dismantled, also can lock and dismantle, and can be used in general four jiaos, hexagonal, anistree and bihexagonal screw simultaneously at the screw of metric system with two kinds of standard specifications made in Great Britain.

Goal of the invention

Goal of the invention of the present utility model is, utilizes this register hole inner ring to be provided with 12 and replaces protrudingly, makes it have lock and establishes gear type, ratchet type and star-like special screw and general screw.

Another goal of the invention of the present utility model is: mat has respectively to be replaced protrudingly at interval adjacent with recessed Kongxiang, it is reached can be used in metric system and two kinds of standard specification screws made in Great Britain simultaneously.

For reaching above-mentioned purpose, the utility model adopts and form a register hole in sleeve body, can by register hole and screw carry out fit and lock, unload operation, it is at register hole inner edge wall, ring is established and is formed 12 and replace protrudingly, and respectively this replaces between protruding at interval adjacent with recessed Kongxiang; This replaces protruding its circular-arc support surface of side moulding, and forms ramp structure in respectively replacing protruding outer end.

Specific embodiment

See also the 1st, shown in Figure 2, ratchet sleeve 10 structures of the present utility model mainly have a body 11, and an end of this body 11 forms a register hole 12; It is characterized in that: these register hole 12 inner rings are provided with 12 and replace protrudingly 13, and this is replaced protruding 13 outer end and forms an inclined-plane 14, and replace protruding 13 side systems and be provided with a circular-arc support surface 15, and between respectively replacing protruding 13 with recessed empty 16 adjacent spaces; The above is the correlation position of each associated component of the utility model and the general introduction of structure thereof.

Make flowing mode and effect in order to clearly demonstrate of the present utility model other, but enumerate a preferable embodiment and cooperate graphic detailed description as after, see also Fig. 3, shown in Figure 4, general gear type screw 20, lie in body 21 outer rims and be equipped with 12 tooth portions 22, and offer a storage tank 23 between each tooth portion 22, when desire is used 10 pairs of gear type screws 20 of ratchet sleeve to lock to establish and dismantle, replacing in the storage tank 23 that protruding 13 correspondences are arranged in this gear type screw 20 of this ratchet sleeve 10, and this replaces tooth portion 22 sides that protruding 13 support surface 15 is resisted against this gear type screw 20, by this, when ratchet sleeve 10 rotates, replace tooth portion 22 sides that protruding 13 support surface 15 is resisted against this gear type screw 20 via this, drive this gear type screw 20 and rotate, this ratchet sleeve 10 is reached lock the purpose of establishing with disengage gear type screw 20.

See also the 5th, shown in six figure, general ratchet type screw 30, lie in body 31 outer rims and be equipped with 12

ratchets

32, and 32 of each ratchets are interconnected to a resistance face 33, when desire is used 10 pairs of ratchet type screws 30 of ratchet sleeve to lock to establish and dismantle, protruding 13 the support surface 15 replaced of this ratchet sleeve 10 is resisted against on the resistance face 33 of this ratchet type screw 30, by this, when ratchet sleeve 10 rotates, be resisted against on the resistance face 33 of this ratchet type screw 20 via this support surface 15 of replacing protruding 13, drive this ratchet type screw 20 and rotate, make this ratchet sleeve 10 reach the purpose that ratchet type screw 30 was established and dismantled to lock.
