The present invention generally relates to a latch structure, and more particular, to a removable self-unlocking structure.
Most electronics use multiple screws to lock frames to the case. Furthermore, electronic products using multiple screws to lock to the case is very time-consuming and laborious, and it is cumbersome and inconvenient when repairing or replacing.
In view of the above drawbacks, the Inventor proposes the present invention based on his expert knowledge and elaborate researches in order to solve the problems of prior art.
Accordingly, an object of the present invention is to provide a removable self-unlocking structure, in which the frame body is provided with an elastic arm and the elastic arm can be positioned at a latching portion of the case for combining with the case.
In order to achieve the object mentioned above, the present invention provides a removable self-unlocking structure for combining with a case having latching portions. The removable self-unlocking structure includes a case and a frame body. The case has a latching portion. The frame body includes a frame plate, and the frame plate is disposed with a positioning structure. The positioning structure includes a slot and an elastic arm exposed in the slot. When the frame body is exerted by an external force, and the elastic arm is capable of positioning at the latching portion or detaching from the latching portion, so that the frame body can slide relative to the case.
Comparing to the prior art, when the removable self-unlocking structure of the present invention is inserted in the case, the frame body can be engaged with the latching portion of the case through the elastic arm of the positioning structure; thereby, the frame body can be quickly positioned in the case without using screws. Moreover, the frame body can be driven to push the elastic arm away from the latching portion. Therefore, the frame body can be removed from the case, and the convenience of use is increased.
The features of the invention believed to be novel are set forth with particularity in the appended claims. The invention itself, however, may be best understood by reference to the following detailed description of the invention, which describes a number of exemplary embodiments of the invention, taken in conjunction with the accompanying drawings, in which:
In cooperation with attached drawings, the technical contents and detailed description of the invention are described thereinafter according to a number of preferable embodiments, not being used to limit its executing scope. Any equivalent variation or modification made according to appended claims is all covered by the claims claimed by the present invention.
Please refer to
The case 10 has a latching portion 11. Furthermore, the frame body 20 is combined in the case 10 in a removable manner and positioned in the case 10 through the latching portion 11. In the present embodiment, the latching portion 11 is a locking hole, but it is not restricted in actual implementation.
The frame body 20 includes a frame plate 21. In the present embodiment, the frame plate 21 is disposed with a positioning structure 22. The positioning structure 22 includes a slot 221 and an elastic arm 222 having at least one part thereof exposed in the slot 221. The frame body 20 is capable of sliding relative to the case 10 by an external force. Thereby, when the frame body 20 slides into the case 10, the elastic arm 222 can be positioned at the latching portion 11 of the case 10, and then the frame body 20 can be combined in the case 10. On the other hand, the elastic arm 222 can be disengaged from the latching portion 11 of the case 10 by an external force, so that the frame body 20 can be removed from the case 10.
In real practice, the removable self-unlocking structure 1 further includes a device body 50. In the present embodiment, the device body 50 is a fan. The frame body 20 covers the device body 50 and is fixed thereon. The device body 50 can be removed through the removable self-unlocking structure 1.
In one embodiment of the present invention, the removable self-unlocking structure 1 further includes a protection plate 30, and the protection plate 30 is provided with a plurality of ventilation holes 31. Specifically, the device body 50 has an air inlet side 51 and an air outlet side 52, and the protection plate 30 is arranged at an outer side of the air inlet side 51 for external air accessing therein and preventing external objects from entering the device body 50.
Preferably, the removable self-unlocking structure 1 further includes a holding assembly 40. The holding assembly 40 is disposed at an outer side of the frame body 20 and is fixed thereon.
It is worth of noting that, in the present embodiment, frame plates 21 located on opposite sides of the device body 50 are provided with a positioning structure 22 separately. Moreover, opposite sides of the case 10 is provided with a latching portion 11 separately corresponding to the positioning structure 22.

In more detail, a bottom of each of the support plates 42 is folded to form a pushing portion 421, and the pushing portion 421 is provided to push the elastic arm 222 away from the latching portion 11.
Please further refer to
It should be noted that, the positioning structure 22 is not limited to the structure aforementioned. In real implementation, the elastic arm 222 can also be directly formed on the frame plate 21 by stamping.
In the present embodiment, the frame plate 21 is disposed with at least one blocking post 23 on a side of the frame plate 21 facing the device body 50, and the at least one blocking post 23 abuts against an edge of the elastic arm 222. In addition, the disposition of the blocking post 23 can prevent the elastic arm 222 from being excessively deformed by an external force; thereby, the positioning effect can be maintained. In the present embodiment, the frame plate 21 is disposed with a plurality of blocking posts 23, and the blocking posts 23 are spaced apart on an outer side of the elastic arm 222.
Please further refer to
It is worth noting that, the pair of supporting plates 42 of the holding assembly 40 are attached to inner sides of the frame plates 21 on both sides, and the pushing portion 421 folded and formed at the bottom of the supporting plate 42 is located at a side of the positioning structure 22. Thereby, the pushing portion 421 can push the elastic arm 222 away from the latching portion 11 to disengage the frame body 20.
