Referring to FIGS. 2, 3 and 4, an embodiment of the locking device of the present invention is suitable for locking a first frame 7 and a second frame 8. The first frame 7 has a surface 71 facing the second frame 8 and two positioning members 72 adjacent to the surface 71. The second frame body 8 has a first frame surface 81 facing the surface 71 and a second frame surface 82 opposite to the first frame surface 81.

The first frame 7 and the second frame 8 are buckled to each other by two locking devices, but the number of the locking devices can also be based on the size of the first frame 7 and the second frame 8 And adjust.

In this embodiment, the positioning members 72 of the first frame 7 are plate members. The positioning members 72 extend along a first direction D1 and are spaced apart in a second direction D2. The positioning members 72 The first frame body 7 is further provided with a sliding groove 73 formed between the surface 71 and the positioning elements 72 in a third direction D3. Each positioning element 72 has two edges along the surface 71. The gaps 721 spaced apart in the first direction D1, each gap 721 extends from the inside to the outside and is connected to the sliding groove 73. The first direction D1, the second direction D2, and the third direction D3 are substantially perpendicular to each other.

Referring to FIGS. 3, 4 and 5, the locking device includes a limiting member 2, a locking member 3, and an operating member 4.

In this embodiment, the limiting member 2 is fixed to the first frame surface 81 of the second frame 8 by two screws 5. The limiting member 2 includes a guide groove 211 surrounding and defining a The limit frame 21 and two stoppers 22 arranged on the limit frame 21.

The locking member 3 is located between the first frame body 7 and the second frame body 8 and passes through the guide groove 211 of the limiting member 2. The locking member 3 can move along the first frame with respect to the limiting member 2. Moving in a direction D1, the buckle member 3 includes a buckle body 31, a limiting block 32, two buckle portions 33, and several positioning portions 34.

The buckle body 31 faces the surface 71 of the first frame 7.

The limiting block 32 extends from the buckle body 31 toward the limiting member 2 and is movably received in the guide groove 211 along the first direction D1. The stopping blocks 22 of the limiting member 2 The limit block 32 used to stop the buckle 3. In this embodiment, the limiting block 32 has two grooves 321, the grooves 321 are respectively formed on two opposite sides in the second direction D2, the limiting frame 21 of the limiting member 2 has four The flanges 212, the flanges 212 are arranged in pairs in pairs and spaced in the first direction D1, each flange 212 extends inward, and the grooves 321 of the stop block 32 are used to engage two of them The flange 212 or the other two flanges 212 are used to position the buckle 3 in the limit frame 21 of the limit member 2.

5, 6 and 7, the buckle portions 33 respectively extend outward from the buckle body 31 on opposite sides of the second direction D2, and the buckle portions 33 are suitable for slidably disposed In the sliding groove 73 of the first frame 7, and used to join the positioning members 72. The width of each buckle portion 33 in the second direction D2 is smaller than the width of each notch 721 of the first frame 7 in the second direction D2.

The positioning portions 34 are arranged in pairs in pairs in the first direction D1 at intervals For the buckle body 31, each positioning portion 34 extends outward along the second direction D2 from the buckle body 31, and is spaced apart from the buckle portions 33 in the third direction D3, and the positioning portions 34 are located The sliding groove 73 of the first frame 7 is suitable for sandwiching the positioning members 72 of the first frame 7 with the buckle portions 33.

In this embodiment, the number of the positioning member 72 of the first frame 7 and the buckle portion 33 of the buckle member 3 are both two, and the number of the locating portion 34 of the buckle member 3 is several, but in other changes In an example, the number of the positioning member 72, the buckle portion 33, and the positioning portion 34 can also be only one, which can also achieve the effect of joining and limiting.

The operating member 4 is disposed on the second frame surface 82 of the second frame 8 and joined to the buckle member 3. The operating member 4 includes an operating portion 41 that can be operated, and an operating portion 41 facing the The first frame surface 81 extends and is connected to the connecting portion 42 of the limiting block 32 of the buckle 3. In this embodiment, the operating portion 41 of the operating member 4 has a rib 411 formed on the outer surface 71 to increase friction, but in other variations, the number of ribs 411 can also be two. the above. In this embodiment, the limiting block 32 of the buckle member 3 has a perforation 322, which is a key hole, and the connecting portion 42 of the operating member 4 has a connecting portion 42 that extends toward the buckle member 3 and penetrates therethrough. The protruding post 421 of the perforation 322 is fixedly connected to the locking member 3 and the operating member 4 by a bolt 6 passing through the limiting block 32 of the locking member 3 and the connecting portion 42 of the operating member 4 together.

Referring to FIGS. 8, 9 and 10, when the operating member 4 drives the buckle member 3 to move along the first direction D1, the buckle portions 33 are engaged with the positioning member of the first frame 7 72 and when it is covered by the positioning member 72, the second frame 8 is snap-locked to the first frame 7. At this time, the locking device is hidden and not exposed.

3, 6 and 7, when the operating member 4 drives the buckle member 3 to move in the first direction D1 so that the buckle portions 33 of the buckle member 3 face the first frame 7 When the notches 721 are formed, the locking member 3 can be separated from the sliding groove 73 of the first frame body 7 by the notches 721 along the third direction D3, so that the second frame body 8 and the first frame body 7 are released They can be separated from each other by locking them.

In this embodiment, the positioning member 72 of the first frame 7 is a plate, but in other variations, the positioning member 72 of the first frame 7 may also be open toward the second frame 8. Hole (not shown), the buckle portion 33 of the buckle member 3 may also be a hook (not shown) that extends from the buckle body 31 toward the opening and is used to engage the opening As long as the buckle portion 33 of the buckle member 3 can be used to buckle the first frame 7.

In the present invention, the buckle member 3 is located between the first frame body 7 and the second frame body 8, and the operating member 4 is disposed on the second frame surface 82 of the second frame body 8. When the buckle lock When the device buckles the second frame 8 to the first frame 7, the buckle member 3 and the operating member 4 can be hidden and not exposed, which is visually more beautiful. In this way, the purpose of the invention can indeed be achieved.

Referring to Figure 11, when the second frame 8 is provided with a foldable gauze 9, since the buckle member 3 is located between the first frame 7 and the second frame 8, and the operating member 4 is provided On the second frame surface 82 of the second frame 8, no matter if the operator is located in the first frame 7 The operating member 4 can be operated to lock the first frame 7 and the second frame 8 on the inside or outside of the second frame 8 in the second direction D2. It should be noted that The foldable gauze 9 is light, thin and flexible. Even if the operator is on the side where the operating element 4 is blocked by the foldable gauze 9, the operator can still press the foldable gauze 9 to operate the operating element 4. Thereby, when the second frame 8 is provided for the foldable gauze 9, the operating member 4 can be operated from the inside or the outside, which has the effect of better ease of use.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
