Detailed Description

Fig. 1 is a schematic perspective view of a locking structure according to an embodiment of the present invention. Fig. 2 is a cross-sectional view of the locking arrangement of fig. 1. Referring to fig. 1 and fig. 2, the locking structure 100 of the present embodiment includes a metal component 110, a non-metal component 120, and a screw component 130. The metal member 110 has a screw hole 110 a. The hardness of the metal piece 110 is greater than that of the non-metal piece 120. The non-metal member 120 is made of, for example, plastic, and is disposed on the metal member 110 and has a through hole 120a, and the through hole 120a is aligned with the screw hole 110 a. The screw 130 is, for example, a screw, which passes through the through hole 120a of the non-metal member 120 and is screwed into the screw hole 110a of the metal member 110, so that the metal member 110 and the non-metal member 120 are fixed to each other by the screw of the screw 130.

Fig. 3 is a partial enlarged view of the locking structure of fig. 2. As shown in fig. 2 and 3, the thread 130a of the locking member 130 is configured to interfere with the inner wall of the through hole 120a of the non-metal member 120, in addition to being configured to be locked to the screw hole 110a of the metal member 110. Therefore, the screw locking member 130 can be more firmly fixed to the metal member 110 and the non-metal member 120, and the probability of loosening the screw locking member 130 can be reduced.

In the present embodiment, the screw threads 130a of the screw locking member 130 are, for example, mechanical threads suitable for being locked to the screw hole 110a of the metal member 110. By designing the aperture of the through hole 120a of the nonmetal member 120 to be the same as or slightly smaller than the aperture of the screw hole 110a, the screw teeth 130a of the screw member 130 may bite into the inner wall of the through hole 120a to interfere therewith as described above in the process that the screw member 130 passes through the through hole 120a and is screw-locked to the screw hole 110 a. That is, in the present embodiment, a partial section of the mechanical tooth for screwing on the metal member is locked and interfered with the plastic member, so as to achieve the above-mentioned effect of firmly fixing the metal member 110 and the non-metal member 120.

In the embodiment, the screw 130 includes a head 132 and a screw 134 connected to each other, the screw 134 passes through the through hole 120a of the non-metal component 120 and is screwed into the screw hole 110a of the metal component 110, and the non-metal component 120 is limited between the head 132 of the screw 130 and the metal component 110, so that the metal component 110 and the non-metal component 120 are fixed to each other. Further, the screw 134 of the screw 130 includes a first section S1 and a second section S2, the first section S1 is located in the through hole 120a of the non-metal element 120, and the second section S2 is located in the screw hole 110a of the metal element 110. The screw threads 130a are formed in the first section S1 and the second section S2, and can be screwed into the screw hole 110a of the metal member 110 and interfere with the inner wall of the through hole 120a of the nonmetal member 120.

The locking structure 100 of the above embodiment can be applied to a robot. That is, the metal part 110 and the nonmetal part 120 may be components included in the robot, so that the components of the robot can be firmly combined. In other embodiments, the locking structure can be applied to other kinds of devices, and the present invention is not limited thereto.

In summary, in the locking structure of the present invention, the screw threads of the screw locking member are used to lock the screw hole of the metal member, and further used to interfere with the inner wall of the through hole of the non-metal member. Therefore, the screw locking piece can be more stably fixed on the metal piece and the nonmetal piece, and the loosening probability of the screw locking piece can be reduced.

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 depart from the spirit and scope of the present invention.
