Description

Lock structure

The present invention relates to a lock structure, and more particularly to a structure for a sliding release state.

With the development of the computer industry, computers have become an indispensable device for people. In recent years, the appearance of computers has become more diverse, and the design of computer casings has received more and more attention. In general, a cover is provided outside some of the specific sockets to prevent the socket from being damaged by external impact or to prevent dust from falling into these sockets. In addition, the cover can be placed outside the socket to make the overall appearance even smoother.

In the current design, when the user wants to open the cover body, a sliding member is usually used to slide against the cover body to open the cover body. However, such a method of opening the cover body is small, resulting in poor results. Therefore, how to design a structure that allows the user to open the cover body conveniently and effectively, and also increase the opening range of the cover body, is an important issue that the industry needs to solve.

In view of the above problems, the present invention relates to a lock structure for improving the problem that the opening width of the cover body is too small.

The locking structure of an embodiment of the invention is used for locking a casing and a cover. The cover body is movably disposed on the housing, and the cover body is displaceable relative to the housing and positioned in one of a closed position and an open position. The locking structure comprises a latching member, a stopping block, a first sliding member and a second sliding member. The snap member is disposed on the cover body. The fastening component has a first fastening portion and a pushing surface. The stop block is fixed to the housing. The first slider is translatably disposed to the housing. The first sliding member has a second fastening portion corresponding to the first fastening portion. The second sliding member is pivoted to the first sliding member. The second sliding member has an interference end corresponding to the stopping block and a pushing end corresponding to the pushing surface.

In the locking structure of the present invention, the second sliding member is pivotally disposed on the first sliding member, and the second sliding member has an interference end corresponding to the stopping block and a pushing end corresponding to the pushing surface. Thereby, the second sliding member can slide along with the first sliding member, and the second sliding member can also pivot relative to the first sliding member and push against the cover body to move the cover body to the open position. In this way, the user only needs to slide the first sliding member to effectively open the cover to a relatively large extent, thereby improving the problem that the opening width of the cover is too small in the prior art.

The above description of the present invention and the following description of the embodiments of the present invention are intended to illustrate and explain the principles of the invention.

The locking structure 10 is used for locking a housing 12 and a cover 14 . The cover 14 is movably disposed on the housing 12. In this embodiment, the cover 14 is pivotally disposed on the housing 12, but is not limited thereto. In other embodiments, the cover 14 can also be slidably disposed on the housing 12, for example.

The locking structure 10 includes a latching member 15, a stop block 16, a first sliding member 18 and a second sliding member 20.

The snap member 15 is disposed on the cover 14 . The latching member 15 has a first latching portion 151, a pushing surface 153 and a side surface 155. One end of the side surface 155 is connected to the first hooking portion 151, and the other end is connected to the pushing surface 153. In this embodiment, the pushing surface 153 is a concave arc surface and has a first end 1531 and a second end 1533. The angle between the first end 1531 and the side 155 is smaller than the angle between the second end 1533 and the side 155. In detail, in this embodiment, The angle between the one end 1531 and the side surface 155 is 25 degrees, and the angle between the second end 1533 and the side surface 155 is 46 degrees (as shown in FIG. 2), but not limited thereto. It should be noted that in the present embodiment, the pushing surface 153 is a concave arc surface, which is not intended to limit the present invention. In other embodiments, the pushing surface 153 may also be a flat surface, and the angle between the pushing surface 153 and the side surface 155 is, for example, 42 degrees. The stop block 16 is fixed to the housing 12.

The first slider 18 is translatably disposed to the housing 12. The first sliding member 18 has a second locking portion 181 , a first pivoting portion 183 and a reset end 185 . The second fastening portion 181 corresponds to the first fastening portion 151 . The reset end 185 is provided with a spring 19. In this embodiment, the reset end 185 is a rod, but is not limited thereto. In this embodiment, the spring 19 is a compression spring, but is not limited thereto. In other embodiments, the spring 19 can also be a tension spring.

The second sliding member 20 has an interference end 201 , a pushing end 203 and a second pivoting portion 205 . The interference end 201 corresponds to the stop block 16. The pushing end 203 corresponds to the pushing surface 153. The second pivoting portion 205 is pivotally disposed on the first pivoting portion 183 .

Please refer to Figure 1, Figure 3 and Figure 4. Figure 3 is a top view of the lock structure in accordance with an embodiment of the present invention and when the interference end contacts the stop block. Figure 4 is a top plan view of the lock structure in accordance with an embodiment of the present invention and when the cover is in the open position.

The cover 14 is movable relative to the housing 12 and is positionable in one of a closed position and an open position. In detail, when the cover 14 is in the closed position, the first fastening portion 151 is buckled to the second fastening portion 181 . Thereby, the cover 14 Firmly fixed in the closed position. When the first sliding member 181 slides toward a first direction D1, the first fastening portion 151 releases the snap-fit relationship with the second fastening portion 181, so that the cover 14 can be disengaged from the closed position. At this time, the pushing end 203 is pushed against the pushing surface 153, and the cover body is moved by a distance in a second direction D2. In the present embodiment, the angle between the first direction D1 and the second direction D2 is 90 degrees, but is not intended to limit the present invention. When the first slider 181 continues to slide toward the first direction D1, the interference end 201 contacts and interferes with the stopper 16 to pivot the second slider 20 toward the pushing surface 153 of the cover 14 and pushes the end 203 Continue to push against the push surface 153. Thereby, the lid body 14 can be moved to the open position (as shown in Fig. 4).

According to the locking structure of the above embodiment, the second sliding member is pivotally disposed on the first sliding member, and the second sliding member has an interference end corresponding to the stopping block and a pushing end corresponding to the pushing surface. Thereby, the second sliding member can slide along with the first sliding member, and the second sliding member can also pivot relative to the first sliding member and push against the cover body to move the cover body to the open position. In this way, the user only needs to slide the first sliding member to effectively open the cover to a relatively large extent, thereby improving the problem that the opening width of the cover is too small in the prior art.

In addition, in this embodiment and other embodiments, since the pushing surface is a concave arc surface, and the angle between the first end and the side surface is 25 degrees, the angle between the second end and the side surface is 46 degrees. Thereby, the user can use the structure to move the cover to the open position more effortlessly.

While the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the scope of the invention. The invention may be modified and modified, and the scope of the invention is defined by the scope of the patent application attached to the specification.
