Abstract
The utility model relates to a gearshift box spanner, which provides a gearshift device arranged on the basis of the original box spanner. The spanner is composed of an external tooth, a middle tooth and an internal tooth, wherein, the internal tooth and an internal tooth shaft (11) are fixedly connected; a middle tooth frame and a middle tooth shaft (5) are fixedly connected. The original force slowing on definite number of turns can increase the intensity of output force after gearshift; when the input force is definite, the output force and the output speed are in inverse proportion. The gearshift box spanner has the advantages of labor saving, time saving and convenient carrying, and is suitable for mounting and dismounting various large middle small type screws.
Description
The utility model speed change box spanner belongs to the peace of screw and unloads instrument.
Motor vehicles in the prior art, machineries such as large ship all need to connect with screw, but unloading screw because of peace brings worry to the technical staff, and peace is unloaded trouble, and the screw wrench of prior art because body is short unable, and can not achieve the goal.Another kind is a box spanner, unloads very painstaking difficulty though this instrument, runs into big screw peace than screw wrench advanced person.
Below also have two kinds, a kind of is electric sleeve barrel, and another kind is a hydraulic-pressure sleeve, and these two kinds all need the energy, not portable.Road driving is broken down, and the screw maintenance is bad and get rusty, and has brought trouble to trained service personnel like this, and it is extremely inconvenient that peace is unloaded screw, twist sometimes motionless, more than two kinds of peaces unload instrument and have a lot of problems, incompatibility field work.
The purpose of the utility model speed change box spanner provides and a kind ofly is provided with a speed change gear on the basis of original sleeve, with original power after speed change, slowly go up certain number of turns, so just can increase its output intensity of force, input power is certain, and the speed of power output and output is inversely proportional to.It is certain promptly to import power, and when output accelerated, power output was less than input power, and when the speed of output was slow, the power of output was greater than input power.
The utility model speed change box spanner takes following method to realize.
The external tooth of speed change box spanner is one and is fixed on a certain position when peace unloaded screw, and internal tooth and internal tooth axle are fixedly connected, and middle braces and medium tooth shaft are fixedly connected, and is provided with a spring that back and forth promotes in internal tooth axle and middle braces chamber.The outer end joint of medium tooth shaft and internal tooth axle also can dock the sleeve of the multiple size of same model.All be provided with at the position of medium tooth shaft and internal tooth axle junction and the mutual pivoting frictions of parts such as external tooth and internal tooth axle and help sliding bearing.The butt joint of power rail and internal tooth axle, sleeve and middle braces have just constituted the sleeve of a quick slack-off speed when connecting, when sleeve when peace is unloaded cap nut, outer ratch adopts with ground and becomes 120 to spend angles, power rail counterclockwise rotates.When cap nut was installed, outer ratch can adopt with ground and become 60 degree angles, and the power rail clockwise direction rotates.When accelerating speed at a slow speed, power rail is through splicing position with its rightabout sleeve head, just sleeve and power rail are replaced mutually, the junction at two is very flexible, penetrating two, back all has down and blocks, this is to prevent from use to take off automatically, clicks the bar of falling cutting ferrule head or power rail and can both distinguish ejection automatically.
The utility model speed change box spanner will further describe in conjunction with the accompanying drawings.
Fig. 1 is the change-speed gearing cross-sectional view of the utility model speed change box spanner.
Fig. 2 is the internal tooth axle and the external tooth schematic diagram of the utility model speed change box spanner.
Fig. 3 is the middle braces and the medium tooth shaft schematic diagram of the utility model speed change box spanner.
Fig. 4 is the structural representation of the utility model speed change box spanner.
Fig. 5 is the work schematic diagram of the utility model speed change box spanner.
With reference to accompanying drawing 1,2,3,4,5, a kind of speed change box spanner be by external tooth (1) when peace is unloaded screw, be fixed on a certain position, make tooth (4) steamboat under the driving of the teeth of internal tooth (3), turn round along external tooth (1), after middle tooth (4) penetrates middle braces (2) location by medium tooth shaft (5), in tooth (4) self rotation when external tooth (1) rotates, it also revolves round the sun under the effect of internal tooth (3), middle gear is provided with more than three, be centered around on the middle tooth (4) with same distance, the number of turns that middle braces (2) rotates is the number of turns of middle tooth (4) revolution.When the utility model speed change box spanner peace was unloaded screw, power rail (9) and internal tooth axle (11) docked, and sleeve (8) and medium tooth shaft (5) are when connecting, and this has just constituted a speed change box spanner.When sleeve (8) was enclosed within on the cap nut that required peace unloads, outer ratch (12) became 120 degree angles with ground, and fixing with fixed bar screw (6), power rail (9) is rotation counterclockwise.Outer ratch (12) adopted with ground and becomes 60 degree angles when cap nut was installed, and power rail (9) clockwise direction rotates.
The utility model speed change box spanner when peace is unloaded king bolt, with king bolt cap peace unload loosening after, essentially no resistance when cap nut unloads rotation in peace, just there are few frictional force in cap nut and bolt, and be laborsaving when therefore rotating.At this moment can be with becoming function fast slowly, specific practice reverses first kind of installation method, and the two ends of speed change box spanner can be exchanged mutually, and power rail (9) is through splicing position with the head of its rightabout sleeve (8).Sleeve (8) is penetrated and its rightabout power rail (9) splicing position, just sleeve (8) and power rail (9) transposition mutually, the junction at two is very flexible, penetrating afterwards, two all has down card (7) and falls to block (10) and block, be to prevent from use to take off automatically, click down card (7) or (10) loop bar head or power rail (9) and can both distinguish ejection automatically, this is because be provided with a spring that back and forth promotes in internal tooth axle (11) and middle braces (2) chamber.The joint of medium tooth shaft (5) and internal tooth axle (11) can dock the sleeve (8) of the multiple size of same model again.Internal tooth axle (11) and internal tooth (3) are fixedly connected, and middle braces (2) and medium tooth shaft (5) are fixedly connected.All be provided with at the position of medium tooth shaft (5) and internal tooth axle (11) junction and external tooth (1) and internal tooth axle mutual pivoting frictions such as (11) and help sliding bearing, to prevent to consume unwanted power.It is time saving and energy saving that the speed change box spanner has, easy to carry, is applicable to that the screw peace of various large, medium and small models is unloaded.
