Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, how to implement the present invention is further explained below with reference to the accompanying drawings and the detailed description.

In a first embodiment, as shown in fig. 1 to 6, a double-ended socket hardware includes a main shaft 1 and two sockets 13 with a plug interface, a transmission device is disposed between the main shaft 1 and the two sockets 13, the transmission device includes a gear set 4 connected to a driving shaft and a transmission shaft connected to the gear set 4, and an output shaft 3 is disposed between the transmission shaft and the sockets 13.

In this embodiment, the sleeves 13 are arranged in parallel in the same direction, so as to conveniently provide a transmission device, wherein the gear set 4 includes a driving gear 41 and two driven gears 42 engaged with the driving gear 41, the driving gear 41 is sleeved on the main shaft 1, and the driven gears 42 are sleeved on the transmission shaft 2.

Be provided with guide 5 between transmission shaft 2 and the output shaft 3, be provided with transmission shaft bayonet lock 9 on the transmission shaft 2, be provided with telescopic output shaft bayonet lock 10 on the output shaft 3, guide 5 is located telescopic edge towards the main shaft direction, is provided with the first draw-in groove 11 with transmission shaft bayonet lock 9 complex semi-closed, and guide 5 middle parts are provided with the second draw-in groove 12 with output shaft bayonet lock 10 complex confined. The output shaft 3 is sleeved with a spring 8, one end of the spring 8 abuts against the sleeve 13, the other end of the spring 8 abuts against the pin sleeve 5, the first clamping groove 11 is V-shaped, the second clamping groove 12 is in the shape of a right-angled triangle, and the axial lengths of the first clamping groove 11 and the second clamping groove 12 are equal. In addition, the groove walls of the first clamping groove and the second clamping groove are arranged to be cambered surfaces as shown in fig. 7, so that the clamping pins can slide conveniently, and the wall surface of the inclined edge of the second clamping groove is also arranged to be cambered surfaces as same as the first clamping groove, so that the clamping pins slide synchronously.

As protection, the main shaft 1 is sleeved with a main bearing 6, the main bearing 6 is sleeved with a main shaft sleeve 7, and a protective shell 14 is arranged, and the protective shell 14 is sleeved outside the gear set 4 and the two pin sleeves 5. And one side of the main shaft sleeve 7 facing the sleeve is provided with a coaming capable of sealing the end face of the protective shell 14.

When the quick-plugging type screw rod driving device is used, the input end of the main shaft 1 is connected with a motor, the output end of the main shaft is connected with the two transmission shafts 2 through the gear set 4, the two transmission shafts 2 are correspondingly connected with the two output shafts 3 through the two pin bushes 5, and the two output shafts 3 are correspondingly connected with the two quick-plugging type screw rods to be operated through the two sleeves 13 with quick plugging interfaces; when the motor rotates, the motor can drive main shaft 1 and rotate, and main shaft 1 drives two transmission shafts 2 through gear train 4 and rotates afterwards, and two transmission shafts 2 can drive two output shafts 3 through two cotter 5 and rotate, and at two output shaft 3 pivoted in-process, lie in 3 terminal sleeves 13 of every output shaft also can be along with rotating, and then reach the purpose that makes the automatic locking of the formula of inserting screw rod soon of treating the operation.

During operation, a bolt at one end is possibly locked first, at the moment, the output shaft at the end is overloaded, the rotation of the transmission shaft enables the pin bush to be subjected to the axial component of the friction force of the transmission shaft bayonet lock and the elastic force of the spring to be smaller than the axial component of the pressure of the transmission bayonet lock on the pin bush, so that the transmission shaft bayonet lock on the transmission shaft slides out of the first clamping groove on the pin bush, the output shaft bayonet lock synchronously slides in the first clamping groove to achieve the effect of disengaging from the transmission shaft, the sleeve at the other end can continuously work, the fact that the pin bush is disengaged from the transmission shaft after the bolt is screwed down is known, and the purpose of preventing the gear from slipping or being damaged by extrusion can be achieved;

when the next operation needs to be carried out at this moment, the guide pin is in the state of breaking away from with the transmission shaft, the output shaft is unloaded or loaded little, then still can be with behind the muffjoint screw rod, the starter motor, first draw-in groove when on the guide pin rotates transmission shaft bayonet lock department, because the rotation of transmission shaft will make the frictional force axial component that receives the transmission shaft bayonet lock on the guide pin and the elasticity of spring be greater than the axial component of transmission bayonet lock to the pressure of guide pin cover, lead to in the transmission shaft bayonet lock slides into first draw-in groove, the output shaft bayonet lock slides in first draw-in groove in step simultaneously, resume transmission effect. Therefore, the utility model discloses a two sleeves can realize the different effect of work but load simultaneously.

Finally, the above description is only the embodiments of the present invention, and not the scope of the present invention is limited thereby, and all the equivalent structures or equivalent processes that are made by the contents of the specification and the drawings of the present invention can be used directly or indirectly in other related technical fields, and all the same principles are included in the scope of the present invention.
