Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
As shown in fig. 1, the present embodiment provides a dual socket wrench which can be freely switched between a manual operation and an electric operation, including: the sleeve head 1 further comprises a mounting seat 2, a first bevel gear 3, a second bevel gear 4 and a locking pin 6. The mounting seat 2 is square or other shapes, and is internally provided with a mounting cavity and a fixing pipe 7 communicated with the mounting cavity is arranged on the side wall. The fixed pipe 7 and the mount 2 are integrally formed.
The first bevel gear 3 and the second bevel gear 4 are in mesh, and the first bevel gear 3 is in rotational connection with the mounting seat 2 via a first central shaft 8, and the second bevel gear 4 is in rotational connection with the mounting seat 2 via a second central shaft 9. Specifically, after the first central shaft 8 extends out of the mounting seat 2, the sleeve head 1 is fixedly connected, the second central shaft 9 extends out of the fixing tube 7 of the mounting seat 2, and the extending end of the second central shaft 9 is provided with the connector 5, so that the sleeve head 1 can rotate by rotating the second central shaft 9. The first bevel gear 3 and the second bevel gear 4 form a reduction gear set, so that the torque of the sleeve head 1 can be increased, and the requirement of a high-torque bolt or nut can be met. The angle between the first bevel gear 3 and the second bevel gear 4 is 90 ° and the diameter of the first bevel gear 3 is larger than the diameter of the second bevel gear 4.
In addition, a fixing rod 10 for supporting the second central shaft 9 is arranged in the mounting base 2, one end of the fixing rod 10 is fixedly connected in the mounting base 2, and the other end of the fixing rod is sleeved on the second central shaft 9 and is rotatably connected with the second central shaft 9. The part of the second central shaft 9 extending out of the fixing pipe 7 is limited through the fixing rod 10, so that the coaxiality of the second central shaft 9 is improved, and the phenomenon that the meshing of the first bevel gear 3 and the second bevel gear 4 is influenced due to overlarge amplitude shaking generated in the rotating process is avoided.
To further ensure the coaxiality, a bearing 11 is provided in the stationary tube 7 for rotational connection with the second central shaft 9. The number of the bearings 11 is two. For longer threaded bolts or nuts, which are screwed more times, the rotational speed of the socket head 1 is usually increased in order to increase the efficiency of the unscrewing or screwing. In order to meet the high speed rotation of the sleeve head 1, it is necessary to ensure that the second central shaft 9 can rotate stably. Two bearings 11 are arranged in the fixed pipe 7, and the two bearings 11 are respectively arranged at the upper part and the lower part of the fixed pipe 7. On the one hand, the stability of the second central shaft 9 in high-speed rotation is ensured, and on the other hand, the friction between the second central shaft 9 and the fixed pipe 7 is reduced, which is beneficial to prolonging the service life of the equipment.
The above structure is the electric mode of the equipment, and the specific rotation principle is as follows: the second central shaft 9 can rotate in the fixed pipe 7 and is connected with an electric drill or other external rotating equipment through the connector 5, so that the second central shaft 9 is driven to rotate, then the first bevel gear 3 and the second bevel gear 4 are in meshing transmission, and finally the sleeve head 1 is driven to rotate. In this mode, the equipment is equivalent to an electric socket wrench, and quick unscrewing or screwing is realized.
The following structure is a manual mode of the device, and the specific structure is as follows:
the second central shaft 9 and the fixed pipe 7 are provided with positioning holes, and the locking pin 6 is inserted into the positioning holes of the second central shaft 9 and the fixed pipe 7 to lock the sleeve head 1. The specific rotation principle is as follows:
the insertion of the locking pin 6 prevents the second central shaft 9 from rotating in the stationary tube 7, in which case the first bevel gear 3, the second bevel gear 4 and the socket head 1 cannot rotate, in which mode the device behaves as a manual socket wrench for manual operation.
This equipment has combined manual box spanner and electric socket spanner's advantage, satisfies multiple user demand. In addition, the two modes of the device can be switched at any time before or during use, and the switching mode is simple and convenient to use.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
