Specific embodiment

The utility model is described in more detail with reference to the accompanying drawings and examples.

The utility model discloses a kind of lock tongue executing agencies for automobile oil filler cap, in conjunction with shown in Fig. 4 to Fig. 9, It includes that the shell 1 is interior to be equipped with drive shaft 2 and slip pipe 3 there are two relatively-stationary shell 1, is formed with cunning in the shell 1 Slot 4, the slip pipe 3 is located in the sliding slot 4 and the two is slidably connected, the first end of the slip pipe 3 pass through the shell 1 and to Outer extension, the drive shaft 2 are inserted into the slip pipe 3 by the second end of the slip pipe 3, and the outer surface of the drive shaft 2 is formed There is external screw thread 5, the inner wall of the slip pipe 3 is equipped with internal screw thread 30, and every circle internal screw thread 30 is made of 3 thread segments 31, two neighboring The angle of the center line of thread segment 31 is 120 °, the 30 phase interworking of internal screw thread of the external screw thread 5 of the drive shaft 2 and the slip pipe 3 It closes.

In above-mentioned lock tongue executing agency, by being specifically designed for internal threads 30 and external screw thread 5, so that internal screw thread 30 and outer The screw thread quantity of screw thread 5 is less, thread density is smaller, and the contact area of internal and external threads is smaller in transmission process, to reduce Resistance between the drive shaft 2 and the slip pipe 3, so that lock tongue executing agency more easily drives, by actual test, The utility model lock tongue executing agency, user only use hand can slip pipe 3 described in pull, it can be seen that, the utility model is not only gram The problem for having taken transmission shaft stretching and return difficulty in the prior art also achieves the manual return unlock of the energy in without electric situation Function prevents the case where cannot opening filler cap under product energization failure generation, has better meet application requirement.

For the ease of motor driving, in the present embodiment, be arranged with driving wheel 6 in the drive shaft 2, the driving wheel 6 with The drive shaft 2 is fixedly connected.Further, the driving wheel 6 is gear.

In order to realize that drive shaft 2 rotates, in the present embodiment, bearing groove 7 is formed in the shell 1, the drive shaft 2 is worn It crosses the bearing groove 7 and the two is rotatablely connected.

To play position-limiting action, in the present embodiment, the first end of the slip pipe 3 is formed with baffle ring 8, when the drive shaft 2 When the slip pipe 3 being driven to retract into the shell 1, the baffle ring 8 is kept out in the outside of the shell 1.

The two sides of the slip pipe 3 are respectively formed with limited block 9 as a preferred method, and the inside of the sliding slot 4 opens up There is limiting slot 10, the limited block 9 is aligned one by one with the limiting slot 10, and the limited block 9 is inserted in the limiting slot 10 And the two is slidably connected.

In the present embodiment, the two sides of the drive shaft 2 offer side grain 20 respectively.Between every two adjacent rings external screw thread 5 Screw pitch be 10mm.

In practical application, the internal screw thread 30 is sequentially distributed along the length direction of the slip pipe 3, along the drive shaft 2 Length direction, the length of the external screw thread 5 are less than the length of the internal screw thread 30.Further, the driving wheel 6 passes through motor Driving operating.

Compared to existing technologies, existing executing agency is all the gear shaft of 2 screw threads, transmission resistance to the utility model Greatly, it is easy to appear clamping stagnation, transmission performance difference low efficiency, effect is undesirable.The utility model is passed using the gear shaft of 3 screw threads It is dynamic, deficiency in the prior art is efficiently solved, and be directed to two kinds of situations of energization movement and no power manual activity, to transmission shaft It is engaged with gear shaft assembly and carries out structural improvement, then the adjustment by parameter and confirmation of drawing a design, the action shaft of every 1PCS Quickly stretching and return, cooperate the lock tongue of front end that locking and unlock to filler cap can be completed, have better meet and answered Use demand.

The above is the utility model preferred embodiment, is not intended to limit the utility model, all practical at this Modification, equivalent replacement or the improvement etc. made in novel technical scope, should be included in the model that the utility model is protected In enclosing.
