Abstract
The utility model provides a rapid transmission accessory for a manual operation socket wrench. The rapid transmission accessory for the manual operation socket wrench comprises a housing, a planetary gear train, a fastening handle, a transmission handle, a spring and splines. A sun gear and a square tenon are manufactured into a whole; a planet carrier and the transmission handle are installed into a whole; and the housing and the fastening handle are manufactured into a whole. The sun gear is installed in the housing; planet gears are installed on the planet carrier and between the inner wall of the housing and the sun gear; the upper portion of the housing is provided with an internal spline which is engaged with an external spline on a lower end shaft of the transmission handle; and a spring is installed between a transmission handle rod and an upper outer end face of the housing. The transmission handle can be pressed down; and the external spline on the lower end shaft of the transmission shaft can be engaged with or disengaged with the internal spline on the upper portion of the housing, and thus acceleration or locking of the planetary gear train can be realized. Upon acceleration, the transmission accessory can be used for rapid installing and dismounting of bolts that have been unscrewed, and, upon locking, the transmission accessory can be used for securing or loosening the bolts. The rapid transmission accessory can be directly used in combination with a conventional standard sleeve.
Description
Technical field
The utility model relates to a kind of driving parts for hand operated square drive socket wrenches, particularly a kind of quick driven accessary.
Background technology
The nut setter spanner is widely used in the mounting or dismounting of hex bolts and nut, and it mainly is comprised of sleeve, driven accessary and coupling.The all standardization of above-mentioned part and transmission side's tenon and square hole.Wherein driven accessary mainly contain swing handle, steering tiller, slide a handle, curved handle, fast seven types of rocking handles, ratchet spanner, convertible ratchet wrench.All these seven kinds of driven accessaries respectively have purposes, wherein quick rocking handle is fit to the rapid-assembling/disassembling of screw bolt and nut, but its fast reason only be that the design of its shape is beneficial to manual fast rotational, do not have acceleration mechanism, and this driven accessary is not suitable for tightening or unclamping fastening screw bolt and nut.
Summary of the invention
For overcoming above-mentioned deficiency, the utility model provides a kind of driving parts for hand operated square drive socket wrenches, particularly a kind of quick driven accessary.
For reaching fast and the fastening dual-purpose purpose of bolt and nut of unclamping, the technical solution adopted in the utility model is: utilize a cover planetary wheeling mechanism as acceleration mechanism, be comprised of shell, planet circular system, fastening handle, driving handle, spring and spline.In the planet circular system, sun gear and square tenon are made into one, and planet carrier and driving handle are installed one, and shell and fastening handle are made into one; Sun gear is cased, and planetary gear is contained on the planet carrier, and between wall and the sun gear, the outer casing inner wall tooth punching is as the planet circular system gear ring in the enclosure in the planetary gear position, and shell upper processing internal spline meshes with driving handle lower end axle external splines; Spring fitting is on driving handle bar and the shell between the outer face, utilize spring, driving handle can be depressed, thereby driving handle lower end axle external splines and shell upper internal spline can be thrown off, realize that planetary wheeling mechanism accelerates or locking, can the rapid-assembling/disassembling bolt and nut during acceleration, can tighten or loosen bolt and nut during locking.
Positive effect of the present utility model is, this driven accessary is can one multiplex, can realize tightening or loosening bolt or nut, the again quickly assembled and disassembled bolt of having unscrewed or nut, using method is simple, efficient is high, and is easy to carry, and can directly support the use with sleeve and the coupling of existing standard.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 side's of being tenon, 2 is sun gear, and 3 is shell, and 4 is fastening handle, and 5-1,5-2 are planetary gear, and 6 is planet carrier, and 7 is external splines, and 8 is spring, 9 is driving handle.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
GB 3390.2-2004-T standard is all adopted in pattern, basic size, the specification requirement of side's tenon 1, to realize and existing coupling and sleeve supporting.In the planet circular system: square tenon 1 and sun gear 2 are to be integrated, and can integral body process and get; Planet carrier 6 is fixed as one with driving handle 9 lower end axles; Sun gear 2 is contained in the shell 3, planetary gear 5-1,5-2 are contained on the planet carrier 6, planetary gear 5-1,5-2 position are between shell 3 inwalls and the sun gear 2, shell 3 inwall tooth punchings are as the effect of planet circular system gear ring, and shell 3 tops also are processed with internal spline and 7 engagements of driving handle 9 lower end axle external splines; Fastening handle 4 is to be integrated with shell 3, can weld or directly process as a whole and get.External splines 7 is fixed on the lower end axle of driving handle 9, also can directly process at driving handle 9 lower end axles, and its path equals the diameter of the axle of driving handle 9.In addition, external splines 7 is shaped as " L " shape, and the lower end ledge is used for preventing deviating from spring 8 effect underdrive handles 9 lower end axle splines.Spring 8 is installed on driving handle 9 bars and the shell 3 between the outer face, utilizes spring 8, and driving handle 9 can be depressed, thereby driving handle 9 lower end axle external splines 7 and shell 3 top internal splines can be thrown off.When driving handle 9 is not depressed, external splines 7 engagements of the internal spline on shell 3 tops and driving handle 9 lower end axles end shell 3 and driving handle 9 lower end shaft locks, because driving handle 9 lower end axles and planet carrier 6 are fixed as one, so planet carrier 6 and shell 3 also locking, whole planet circular system becomes one, apply moment, can be fastening or unscrew bolt.When overcoming the elastic force screwdown driving handle 9 of spring 8, driving handle 9 lower end axle external splines 7 are thrown off with shell 3 top internal splines.Rotate planet carrier 6 by driving handle 9, realize that the acceleration of sun gear 2 is rotated, can accelerate to twist and revolve bolt.
During actual use the utility model pine bolt, first fastening handle 4 is applied moment, unclamp bolt, then with the fixing fastening handle 4 of a hand, driving handle 9 is pressed and rotated to the another hand, the bolt of just can back-outing post.Otherwise process when bolting on.
Claims (1)
1. quick driven accessary of nut setter spanner, formed by shell, planet circular system, fastening handle, driving handle, spring and spline, it is characterized in that: in the planet circular system, sun gear and square tenon are made into one, planet carrier and driving handle are installed one, shell and fastening handle and be made into one; Sun gear is cased, and planetary gear is contained on the planet carrier, and the planetary gear position is in the enclosure between wall and the sun gear, and the outer casing inner wall tooth punching is as the planet circular system gear ring, shell upper processing internal spline, processing " L " shape external splines on the axle of driving handle lower end; Spring fitting utilizes spring on driving handle bar and the shell between the outer face, and driving handle can be depressed, thereby driving handle lower end axle external splines and shell upper internal spline can be thrown off.
