Card lock structure

The present invention relates to a latch structure, and more particularly to a latch structure for locking a hard disk to an electronic product.

The hard disk of the prior electronic product is mostly disposed in the hard disk extracting device, and the hard disk extracting device is used to extract the hard disk from the electronic product when the user needs to replace or repair the hard disk. The front end of the hard disk extracting device is generally provided with a latching structure for fixing the hard disk extracting device to the frame of the electronic product. The latching structure generally includes a handle, a handle base, a tab slider and a button. The handle, the tab slider and the button are respectively mounted in the handle base. One end of the button is engaged with the handle to lock the tab slider by a handle to perform locking. When the user pulls the hard disk, the button needs to be pushed to retract the tab slider into the handle seat and eject the handle. Since the latch structure needs to control the movement of the handle and the tab slider by setting a button, the latch structure has many internal components and a complicated structure, which increases the manufacturing cost.

In view of this, it is necessary to provide a simple structure of the latch structure.

A latch structure includes a handle, a handle base and a latch slide. The handle includes a pressing tab. The handle base includes a receiving portion and a bump through hole and a tongue through hole formed on the handle base and communicating with the receiving portion. The handle is pivotally connected to the handle base. The pressing protrusion protrudes from the through hole of the bump into the receiving portion. The latch slide includes a tab. The latching slider is slidably received by the handle seat by a spring In the accommodating portion, the tab protrudes from the tab through hole. When the handle is turned away from the handle seat, the pressing protrusion drives the latching slider to slide away from the through hole of the tab, and the tab is retracted into the receiving portion of the handle seat to release the lock Hehe.

Compared with the prior art, the card lock structure provided by the present invention is configured to press the handle pivotally connected with the handle base to press the latch slider sliding in the handle seat, thereby controlling the tab on the latch slider to extend. Or retract into the handle to achieve the lock function. Because the card lock structure provided by the invention only needs to provide a handle and a latching slider, the locking function can be realized, the components are few, and the structure is simple, thereby reducing the manufacturing cost.

A bump through hole 120a is defined in the front cover 120 corresponding to the pressing protrusion 160 of the handle 10. A pair of second pivoting portions 123 are disposed corresponding to the first pivoting portion 104 at a position corresponding to the second through-holes 120a, and are disposed at the center of each of the second pivoting portions 123. There is a second mounting hole 123a. A pivotal notch 125 is defined in the outer side surface 122b of the second side wall 122 corresponding to the first pivoting portion 104 of the handle 10. The inner side surface 122a of the second side wall 122 extends perpendicularly outwardly from the protrusion through hole 120a, and a plurality of first limiting blocks 127 are disposed in parallel with each other. The first limiting block 127 is away from the front end of the front cover 120. Align. The inner side surface 122a of the second side wall 122 extends perpendicularly from the side of the front cover 10 to the pair of second limiting blocks 128 in a direction parallel to the front cover 120. A passage 129 is formed between the first limiting block 127 and the second limiting block 128, and the locking slider 14 is slidable along the passage 129. A latching through hole 124a is defined in the middle of the top cover 124. The top cover 124 extends from the two sides of the latching through hole 124a toward the receiving portion 126 to extend a pair of first hooks 124b.

The latching slider 14 includes a pair of third side walls 140, a top plate 142, a pressing side wall 144, a pair of guiding arms 146, a tab 148 and a pair of second hooks 149. The third side walls 140 are disposed in parallel with each other. The top plate 142 is perpendicularly connected to the third side wall 140. The pressing sidewalls 144 are respectively connected to the top plate 142 and the third sidewall 140, and are inclined to the top plate 142. angle. The pressing sidewall 144 includes a second abutting surface 144a. The guiding arm 146 is formed by extending perpendicularly in the opposite direction from the outer side surface of the third side wall 140. The tab 148 is formed by a central portion of the top plate 142 extending perpendicularly away from the top plate 142. The top plate 142 is respectively provided with the second hook 149 on both sides of the tab 148.

Referring to FIG. 3 and FIG. 5 together, the latching slider 14 is received in the receiving portion 126 of the handle base 12 during assembly. The tab 148 is extended by a tab through hole 124a on the top cover 124. The guiding arm 146 slides along the passage 129 between the first limiting block 127 and the second limiting block 128 to guide the sliding direction of the locking slider 14 . The first hook 124b on the handle base 12 and the second hook 149 on the latch slider 14 are connected by the spring 16. The pressing protrusion 106 on the handle 10 extends through the through hole 120a of the handle base 12 into the receiving portion 126 of the handle base 12, and the second pressing surface 144a and the first portion A pressing surface 106a matches. The first pivoting portion 104 of the handle 10 is received in the corresponding pivoting notch 125 of the handle base 12, and the first mounting hole 104a and the second pivotal portion of the first pivoting portion 104 are respectively The second mounting holes 123a of the connecting portion 123 are aligned with each other, and the positioning pins 18 are respectively fixed in the second mounting holes 123a through the first mounting holes 104a, thereby pivoting the handle 10 to the handle seat 12. on.

When the latching structure 1 is in the locked state, the latching slider 14 is suspended by the spring 16 on the top cover 124 of the handle base 12. The first pressing surface 106a of the pressing protrusion 106 and the second pressing surface 144a of the pressing side wall 144 cooperate with each other. The tab 148 is extended by the bump through hole 120a of the handle base 12 to be locked.

Referring to FIG. 6 together, when it is necessary to release the lock, the handle 10 is turned in a direction away from the handle base 12. At this time, the pressing protrusion 106 of the handle 10 presses against the pressing side wall 144 of the locking slider 14 to drive the locking slider 14 away from the passage 129 on the handle base 12 The direction of the top cover 124 slides while stretching the spring 16. The tab 148 is retracted into the receiving portion 126 of the handle base 12 in a direction away from the top cover 124 with the latching slider 14 to release the lock.

It can be understood that the latch structure 1 can be mounted on a sliding device such as a hard disk extracting device, a drawer, a door, a window or the like to lock the sliding device.

The latch structure provided by the present invention is configured to press a latch slidingly connected to the handle base to press the latch slider sliding in the handle seat, thereby controlling the tab on the latch slider to extend or retract into the handle seat To achieve the lock function. Because the card lock structure provided by the invention only needs to provide a handle and a latching slider, the locking function can be realized, the components are few, and the structure is simple, thereby reducing the manufacturing cost.
