[0027] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0028] The present application embodiment provides a locking mechanism, such as Figure 1 , Figure 2 As shown, including:
[0029] The lock body is formed with a guide groove adapted to the lock tongue 6. In some embodiments, the lock body includes an upper lock body 4 and a lower lock body 5, wherein the upper lock body 4 is fixedly connected to the lower lock body 5 to form a guide groove adapted to the lock tongue 6. Figure 1 , Figure 2 As shown, the lower lock body 5 and the upper lock body 4 are fixed together, and the lock tongue 6 is sandwiched in the middle. The lock tongue 6 can move left and right in the space (guide groove) between the lower lock body 5 and the upper lock body 4.
[0030] The locking tongue 6 has a traction portion at one end, for example Figure 1 , Figure 2 The pull ring shown in the figure has no specific structure limitation, and the other end is connected to the lock tongue hole 7, and the middle part of the lock tongue 6 is connected to the lock body through a spring 8.
[0031] The guide groove is provided with a guide groove on its side wall, and a guide pin is provided at a corresponding position of the side wall of the lock tongue 6, so that when the lock tongue 6 is pulled, the spring 8 is pulled up and the lock tongue 6 moves along the direction of the guide groove based on the guide pin.
[0032] In some embodiments, the guide groove is provided on the side wall between the upper lock body 4 and the lower lock body 5, and a guide pin is provided at the corresponding position of the side wall of the lock tongue 6. The guide groove is used to guide the lock tongue 6, and the specific shape of the guide groove can be set according to actual needs.
[0033] The lock structure of the embodiment of the present application adopts a lock tongue in a specific example to achieve the purpose of locking the movable structure of the connecting rod. During the locking process, the lock tongue can automatically swing around the connecting rod, so as to achieve the effect of minimizing the installation height of the lock mechanism after locking.
[0034] For some specific examples, see Figure 3 As shown, the upper lock body 4 is designed with guide grooves 14 and 15, which can cooperate with guide pins 16 and 17 on the lock tongue 6, and the guide pins 16 and 17 can be inserted into the guide grooves 14 and 15, and the lock tongue 6 can slide left and right along the guide grooves. The guide grooves 14 and 15 are non-straight and irregular in shape. When the lock tongue 6 slides, the guide pins change the direction of the lock tongue 6 according to the shape of the guide grooves.
[0035] For some specific examples, see Figure 4 As shown, the lower lock body 5 is designed with guide grooves 9 and 10, which can cooperate with guide pins 11 and 12 on the lock tongue 6, and guide pins 12 and 13 can be inserted into the guide grooves 9 and 10, and the lock tongue 6 can slide left and right along the guide grooves. The guide grooves 9 and 10 are non-straight and irregular in shape. When the lock tongue 6 slides, the guide pins change the direction of the lock tongue 6 according to the shape of the guide grooves.
[0036] In some embodiments, Figure 5 , Figure 6 As shown, a first buckle 11 is provided on one end of the guide groove on the lower lock body 5 close to the lock tongue hole 7, and a second buckle 20 is provided at a position of the lock tongue 6 opposite to the first buckle 11, so as to access the spring based on the second buckle 20 and the first buckle 11.
[0037] A first buckle 11 is also provided on the lower lock body 5 , and the first buckle 11 can fix one end of the spring 8 .
[0038] In some embodiments, the number of the guide grooves and the guide pins is 4, which are respectively arranged on the two side walls of the guide groove and the two side walls of the locking tongue 6.
[0039] In some embodiments, the locking tongue 6 is linear as a whole, and there is an offset between the portion of the locking tongue 6 connected to the spring and the other end of the locking tongue 6 .
[0040] In some embodiments, the locking tongue hole 7 is provided with a groove 21, and the other end of the locking tongue 6 is provided with a tongue 18. Under normal conditions, the tongue 18 is inserted into the groove 21 on the locking tongue hole 7.
[0041] In a specific example, Figure 5 , Figure 6As shown, the lock tongue 6 is provided with guide pins 12, 13, 16 and 17, a total of 4 guide pins, which can be respectively inserted into the guide grooves 9 and 10 on the lower lock body 5 and the guide grooves 14 and 15 on the upper lock body 4. The lock tongue 6 can slide along the guide grooves, and when sliding, the guide grooves will guide the lock tongue 6 to change its direction.
[0042] like Figure 5 , Figure 6 As shown, a handle 19 is provided on the lock tongue 6, and the user can slide the lock tongue 6 to the left through the handle 19. A tongue 18 is provided on the lock tongue 6. When the lock tongue 6 slides to the rightmost end, the tongue 18 will be inserted into the groove 21 on the lock tongue hole 7. When the lock tongue 6 slides to the left, the tongue 18 will be out of the groove 21 on the lock tongue hole 7. A second buckle 20 is provided on the lock tongue 6, and the second buckle 20 can fix the other end of the spring 8. The spring has a specific length and has a tendency to pull the lock tongue 6 back to the rightmost side.
[0043] like Figure 7 As shown, the lock bolt hole 7 is provided with a groove 21. When the lock bolt 6 moves to the rightmost end, the tongue 18 on the lock bolt 6 will penetrate into the groove 21 and get stuck.
[0044] The lock mechanism of the present application adopts a lock tongue to lock the movable structure of the connecting rod, and is suitable for locking a movable connecting rod. During the locking process, the lock tongue can automatically swing around the connecting rod, so as to achieve the effect of minimizing the installation height of the lock mechanism after locking.
[0045] The embodiment of the present application also proposes a device that completes locking based on the locking mechanism as described above.
[0046] The exemplary use scenario proposed in this application is that the lock mechanism 3 is installed on the device surface 1 to lock the connecting rod 2 on the device surface 1 so that the connecting rod 2 cannot move along the rotation axis. Figure 8 , Fig. 9 As shown, when in use, the handle 19 on the lock tongue 6 of the lock mechanism 3 is pulled to the left, and the tongue 18 on the lock tongue 6 of the lock mechanism 3 leaves the groove 21 of the lock tongue hole 7 of the lock mechanism 3, and the connecting rod 2 is rotated to the space formed by the lock mechanism 3 and the device surface 1, so that the connecting rod 2 is close to the device surface 1, and then the handle 19 on the lock tongue 6 of the lock mechanism 3 is released, and the lock tongue 6 slides to the right under the pulling force of the spring 8. During the sliding process, the lock tongue 6 will move according to the guide path designed by the guide grooves 9 and 10 on the lower lock body 5 and the guide grooves 14 and 15 on the upper lock body 4. During the movement, the tongue 18 on the lock tongue 6 bypasses the connecting rod 2, and when it moves to the rightmost, it is inserted into the groove 21 of the lock tongue hole 7 of the lock mechanism 3, and the lock mechanism locks the connecting rod 2.
