Detailed Description

For fully understanding the objects, features and functions of the present invention, a detailed description will be given of the present invention through the following specific embodiments in conjunction with the accompanying drawings, which are described as follows:

please refer to fig. 1, which illustrates a first embodiment of a locking structure 1001 with grooves according to the present invention. The rotation locking structure 1001 sequentially includes a head 1100, a rod 1200 and a locking portion 1300 from top to bottom, the rod 1200 is connected to the bottom surface of the head 1100, and the locking portion 1300 is connected to the bottom surface of the rod 1200.

The locking portion 1300 has a first groove 1310 and a second groove 1320; the first groove 1310 is concavely arranged on the side surface of the fastening part 1300, and extends upwards for a certain distance from the bottom of the fastening part 1300, and the bottom of the first groove 1310 is communicated with the bottom surface of the fastening part 1300; the second groove 1320 is recessed in a side surface of the locking portion 1300, and extends a distance from a top end of the first groove 1310 to the right or left, and the first groove 1310 is communicated with the second groove 1320.

Next, please refer to fig. 2 to 4, which are schematic diagrams illustrating a process of combining the first embodiment of the twist-lock structure 1001 with two objects (i.e., a first object 10 and a second object 20).

First, as shown in fig. 2 and 3, a user first passes the twist-lock structure 1001 through a hole of the first object 10 and then passes through a hole of the second object 20; a protrusion 21 of the edge of the hole of the second object 20 corresponds to the first groove 1310 of the locking portion 1300 of the locking structure 1001.

Next, as shown in fig. 4, when the user moves the protrusion 21 of the second object 20 from the bottom of the first groove 1310 of the locking portion 1300 to the joint of the first groove 1310 and the second groove 1320, the rotation-locking structure 1001 is rotated, so that the protrusion 21 of the second object 20 moves to the second groove 1320 of the locking portion 1300 transversely. By this action, the locking portion 1300 of the locking structure 1001 can lock the second object 20 and fix the first object 10 at the same time.

As can be seen from the above and the accompanying drawings, the structure of the rotation-locking structure 1001 is simple, so that a user can easily fix the first object 10 and the second object 20 through the rotation-locking structure 1001; in addition, since the structure of the twist-lock structure 1001 is simple, the first object 10 and the second object 20 can be fixed by the twist-lock structure 1001, and therefore the structural strength of the first object 10 and the second object 20 is not damaged; furthermore, the second object 20 can be a very thin plate, so it should be understood that the twist-lock structure 1001 can be applied to a thinner object.

Referring to fig. 4 again, a first included angle θ 1 is formed between the first groove 1310 and the bottom surface of the locking portion 1300, the first included angle θ 1 is 60 ° to 120 °, and the first included angle θ 1 is preferably 90 °; in addition, the width W1 of the first groove 1310 is greater than the width W2 of the second groove 1320, so that the bump 21 of the second object 20 can move; furthermore, the depth of the first groove 1310 is greater than that of the second groove 1320, so that the bump 21 of the second object 20 can move.

In addition, as shown in fig. 1 to 4, the second groove 1320 extends a distance to the right from the top end of the first groove 1310, but is not limited thereto, and the second groove 1320 may also extend a distance to the left from the top end of the first groove 1310; furthermore, the second grooves 1320 may extend horizontally, or may extend slightly upward or downward; furthermore, the second groove 1320 may also extend a distance from the side of the first groove 1310, such that the first groove 1310 protrudes from the second groove 1320.

Furthermore, although not shown, the shaft 1200 may be an elongated cylinder to facilitate a user to pass the shaft 1200 through the hole of the first object 10.

Furthermore, although not shown, the locking portion 1300 further has a bump (not shown) protruding into the second groove 1320. Through the design of the bump, the bump 21 of the second object 20, which is already located in the second groove 1320, can be prevented from sliding out of the first groove 1310.

Moreover, when the second object 20 is made of an elastic material, the bottom of the first groove 1310 does not need to be communicated with the bottom surface of the locking portion 1300, and a user only needs to apply a large force on the rotation-locking structure 1001 to lock the protrusion 21 of the second object 20 into the first groove 1310.

Next, please refer to fig. 5, which is a schematic diagram of a second embodiment of the twist-lock structure 1002 according to the present invention and two objects.

The sleeve 1400 has a second limiting portion 1410 disposed on an inner sidewall of the sleeve 1400, preferably near the top of the sleeve 1400 or near the middle of the sleeve 1400; and an assembling portion 1420 disposed at the bottom of the sleeve 1400 for assembling the first object 10; the first position-limiting portion 1210 and the second position-limiting portion 1410 are movably interfered with each other, so that the sleeve 1400 is movably combined with the rod portion 1200 and cannot be separated from the rod portion. By this design, the sleeve 1400 can protect the rod portion 1200 and the fastening portion 1300. In addition, although not shown, the locking structure 1002 further includes an elastic element (not shown), two ends of which respectively abut against the bottom of the head 1100 and the top of the sleeve 1400, so that the sleeve 1400 elastically moves relative to the fastening portion 1300.

Next, please refer to fig. 6, which is a combination diagram of a third embodiment of the twist-lock structure 1003 according to the present invention and two objects. The design of the twist-lock structure 1003 is substantially the same as that of the twist-lock structure 1002, wherein the sleeve 1400 further has a hollow stop 1430 disposed inside the sleeve 1400 and located below the second position-limiting portion 1410, and the hollow stop 1430 and the second position-limiting portion 1410 are movably interfered with each other, so that the sleeve 1400 is movably combined with the rod 1200 and cannot be separated from each other.

In addition, it should be understood that the design of the sleeve 1400 of the twist-lock structure 1002 or the twist-lock structure 1003 allows the user to snap the first object 10 and the second object 20.

The two ends of the elastic component 1500 respectively abut against the bottom of the head 1100 and the abutting portion 1440, so that the sleeve 1400 performs an elastic motion relative to the cap body 1110. The elastic component 1500 is a spring, a spring washer, an elastic washer, or an elastic cylinder. Additionally, it should be understood that the abutting portion 1440 and the resilient element 1500 can be omitted by a user.
