Abstract

The present disclosure provides a lockable case including a frame body, an upper cover, a lower cover and a locking mechanism. The locking mechanism includes a rotating module and a transmission bar. The locking module includes a rotating portion, an upper-cover-limiting portion, a lower-cover-limiting portion, and a pushing portion. The upper-cover-limiting portion is configured to restrict an upper-cover-limited portion. The pushing portion is connected to the rotating portion and is moved simultaneously with the rotating portion. The transmission bar is push by the pushing portion to switch from a first position to a second position. The transmission portion includes a lower-cover-limiting portion configured to restrict a lower-cover-limited portion. As the rotating portion is rotated, the upper-cover-limiting portion switches from a releasing position to a locking position for restricting the upper-cover-limited portion, and the pushing bar switches to a pushing position to push the transmission bar to a second position to allow the lower-cover-limiting portion to restrict the lower-cover-limited portion. Therefore, the using convenience can be increased.

Description

Lockable case

The present invention relates to a casing, and in particular to a lockable casing whose upper and lower covers can be opened.

A general casing includes a cover and a frame. The frame surrounds and forms an accommodating space to accommodate components. The cover covers the frame and closes the accommodating space, and can be further locked to prevent the cover from being opened arbitrarily. When the case is applied to electronic products, such as the main case of an electronic device, it is often configured with a structure in which the upper and lower covers can be opened, and in order to prevent the upper and lower covers from being opened, two sets of locks will be installed on the upper and lower covers respectively. It is cumbersome to operate, cannot be effectively utilized in space configuration, and has the disadvantages of high cost and low assembly efficiency.

In view of this, how to improve the structural configuration of the lockable casing with the upper and lower covers openable has become the goal of relevant industry players.

Thereby, when the rotating part 1411 rotates, the upper cover limiting part 1412 and the pushing part 1413 can be rotated in conjunction, so that the upper cover limiting part 1412 turns from the release position to the locking position, and the pushing part 1413 moves away from a position Switch to push-in position. Furthermore, the rotating part 1411 may include a lock hole 1411a for a key to be inserted, so that the upper cover 1100 and the lower cover 1200 can be opened or locked by the key.

The locking mechanism 1400 further includes a fixing frame 1430 , the fixing frame 1430 is disposed in the frame body 1300 and includes a track 1431 , and the transmission rod 1420 is limited to move in the track 1431 . The fixing frame 1430 includes two side frame parts 1432, 1433, wherein one side frame part 1432 is connected and locked to one side plate of the frame body 1300, and the other side frame part 1433 can abut against other components in the frame body 1300, and the side frame part Portion 1433 may be recessed to form track 1431 . The structure of the fixing frame 1430 is not limited thereto.

The transmission rod 1420 includes an inclined surface 1421 and a rod portion 1422 , the rod portion 1422 extends between the upper cover 1100 and the lower cover 1200 , and the rod portion 1422 is accommodated in the track 1431 . The inclined surface 1421 is disposed at an end of the rod portion 1422 adjacent to the upper cover 1100 , and the inclined surface 1421 is used for being pushed by the pushing portion 1413 . The lower cover limiting part 1423 can be disposed on one end of the rod part 1422 adjacent to the lower cover 1200 and has a hole structure, and the lower cover locking part 1210 can cooperate with it to have a protruding pin structure.

In addition, the transmission rod 1420 can further include a groove 1424 , the fixing frame 1430 can further include a protrusion 1434 , and the protrusion 1434 protrudes into the groove 1424 , and the locking mechanism 1400 can further include a spring 1440 , and the spring 1440 is located in the groove 1424 and is pressed against by the convex portion 1434 . In detail, the extending direction of the groove portion 1424 is parallel to the extending direction of the rod portion 1422 , and the protruding portion 1434 is protruded from the side frame portion 1433 and located in the track 1431 . Therefore, when the transmission rod 1420 is accommodated in the track 1431 , the protrusion 1434 can protrude into the groove 1424 , so that the spring 1440 can be clamped between the protrusion 1434 and an upper groove surface of the groove 1424 .

Please refer to Figures 5 and 6, and also refer to Figures 2 to 4, wherein Figure 5 shows a partial top view of the lockable casing 1000 of the embodiment in Figure 1, and Figure 6 A partial side view of the lockable casing 1000 of the embodiment shown in FIG. 1 is shown. In FIG. 5 and FIG. 6, the upper cover limiting portion 1412 and the pushing portion 1413 are located at the locked position and the distanced position respectively, and the transmission rod 1420 is located at the first position. Therefore, the upper cover limiting part 1412 does not hook the upper cover locking part 1110, and the pushing part 1413 does not push against the inclined surface 1421 of the transmission rod 1420, so the lower cover limiting part 1423 of the transmission rod 1420 does not limit the lower cover locking part. 1210, that is to say, the upper cover 1100 and the lower cover 1200 are in an unlocked state at this time.

Please refer to Figures 7 and 8, and also to Figures 2 to 4, wherein Figure 7 shows another partial top view of the lockable casing 1000 of the embodiment in Figure 1, and Figure 8 The figure shows another partial side view of the lockable casing 1000 of the embodiment in FIG. 1 . Slide the upper cover 1100 on the upper edge of the frame body 1300 to fasten the upper cover fastening part 1120 to the frame body 1300, and slide the lower cover 1200 to the lower edge of the frame body 1300 to make the lower cover fastening part 1220 fasten to the frame body 1300. After the slot 1310 on the lower edge of the frame body 1300, the key can be inserted into the lock hole 1411a, and the rotating part 1411 is rotated toward the locking direction R1. At this time, the upper cover limit part 1412 rotates to the locking position and hooks the upper cover lock part 1110 , which can prevent the upper cover 1100 from being pulled away in the opposite direction; at the same time, the pushing part 1413 is turned to the pushing position and contacts the inclined surface 1421 of the transmission rod 1420, and the rod part 1422 of the transmission rod 1420 is pressed down by the structure of the inclined surface 1421. At this time The groove part 1424 is moved downward by linkage and makes the spring 1440 compress and store force, and the lower cover lock part 1210 enters the lower cover limit part 1423, which can also prevent the lower cover 1200 from being pulled away in the opposite direction, and make the upper cover 1100 and the lower cover 1100 The cover 1200 is locked.

When the user intends to open the upper cover 1100 and the lower cover 1200, just insert the key into the lock hole 1411a, and turn the rotating part 1411 in the opposite direction, so that the upper cover limit part 1412 can be separated from the upper cover lock part 1110, so that the upper cover 1100 is not restricted by the upper cover. The position part 1412 is restricted, and the pushing part 1413 is switched back to the away position, the inclined surface 1421 of the transmission rod 1420 is not stressed, the spring 1440 can be released and the transmission rod 1420 can be pushed back to the first position, so that the lower cover lock part 1210 is disengaged from the lower The cover limiting portion 1423 and the lower cover 1200 are not restricted by the lower cover limiting portion 1423 , the upper cover 1100 and the lower cover 1200 can return to the unlocked state in FIG. 5 and FIG. 6 .

Although the present invention has been disclosed as above with the embodiments, it is not intended to limit the present invention. Anyone skilled in this art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection of the present invention The scope shall be defined by the appended patent application scope.
