Fig. 4 shows the arrangement of the handle of the locking mechanism shown in fig. 1 in a front view of the second part. For the purpose of illustration, the drawings show only the structures pertinent to the present invention.

As shown in fig. 1, 2 and 3, a locking mechanism provided in an embodiment of the present invention is used to assemble a first component 100a and a second component 100b located below the first component 100 a. The first member 100a and the second member 100b may be a case of the display device, or may be other members. The first member 100a and the second member 100b may have the same or different structures. That is, the structure and use of the first member 100a and the second member 100b are not limited to the display device.

In this embodiment, the locking mechanism includes a female lock 10, a male lock 20, and a handle 30. The female lock 10 is fixedly mounted to the first member 100 a. The male latch 20 includes a lock lever 21, and the lock lever 21 is movably connected to the second part 100b in the up-down direction. During the upward movement of the lock bar 21, the top end of the lock bar 21 can be inserted into the female lock 10 and be connected with the female lock 10 in a snap-fit manner. The bottom end of the lock rod 21 is provided with an abutting surface 212 (see fig. 5), and the abutting surface 212 can be abutted by the index finger and lift up the lock rod 21.

The handle 30 is fixedly connected to the second component 100b, a first operating channel is provided between the handle 30 and the lock rod 21 for the food fingers to extend to the abutting surface 212 and lift up the lock rod 21 when holding the handle, so that the handle 30 can be held by two hands, the male lock 20 and the female lock 10 are aligned and held, meanwhile, the abutting surface 212 at the bottom end of the lock rod 21 can be pressed by an index finger, the lock rod 21 is lifted up, the lock rod 21 is inserted into the female lock 10 and clamped with the female lock 10, and the second component 100b is hung on the first component 100 a.

The locking mechanism is configured to hold the handle 30 with both hands during use, and lift the second member 100b such that the male lock 20 mounted on the second member 100b is aligned with and retained by the female lock 10 mounted on the first member 100 a. Then, the holding surface 212 at the bottom end of the lock bar 21 of the male lock 20 is pressed by the index finger, so that the lock bar 21 moves upward, and is inserted into the female lock 10 and engaged with the female lock 10. At this time, the second member 100b is hung on the first member 100a by the engagement of the lock lever 21 and the female lock 10, and the male lock 20 is further operated to lock, thereby achieving the joining of the first member 100a and the second member 100 b.

The preset distance can be determined according to the length of the forefinger, so that when the handles are held by two hands, the forefinger can extend to the abutting surface at the bottom end of the lock rod, and the pressing operation is convenient. Alternatively, the preset distance may be 3cm to 20 cm. Preferably, the preset interval may be 3cm to 12 cm. Therefore, the abutting surface at the bottom end of the lock rod 21 can be pressed upwards by the index finger more conveniently, and the operation difficulty is further reduced. In one embodiment, the distance between the handle 30 and the lock lever 21 may be 6 cm.

Fig. 5 shows a cross-sectional structure of the male and female locks of the locking mechanism shown in fig. 1. FIG. 6 shows the configuration of the snap connection of the male and female locks of the locking mechanism of FIG. 1. Fig. 7 is an exploded view of the female lock of the locking structure shown in fig. 1.

Referring to fig. 5, 6 and 7, in an embodiment of the present invention, the female lock 10 includes an operating handle 12, and the female lock 10 is separated from the lock lever 21 by operating the operating handle 12;

the operating handle 12 is located above the handle 30, and a second operating channel is provided between the operating handle 12 and the handle 30 for the thumb to extend to the operating handle 12 and operate the operating handle 12 when the handle 30 is held.

In some embodiments, the female lock 10 further includes a lock base 13 fixedly mounted to the first member 100a, and a snap assembly (not shown).

The lock base 13 has an inner cavity and a lock hole 1302 communicated with the inner cavity, and a clamping assembly is disposed in the inner cavity and used for clamping and connecting with the lock rod 21 when the lock rod 21 moves upwards and is inserted into the inner cavity through the lock hole 1302. Thus, when the pressing surface 212 at the bottom end of the lock bar 21 is pressed by the index finger, the lock bar 21 is moved upward, and is inserted into the lock hole 1302 and connected with the clamping component in a clamping manner. When it is desired to disassemble the first part 100a from the second part 100b, the latch assembly is operable to disengage the latch assembly from the locking bar 21.

The operating handle 12 is located outside the lock base 13 and connected with the clamping assembly, and the clamping assembly can be separated from the lock rod 21 by operating the operating handle 12. Thus, when disassembly is required, the male lock 20 is first operated to change the locking state of the male lock 20 into the unlocking state. Then, the handle 30 is held by both hands to lift the second part 100b, and the operating handle 12 is operated by the thumb to separate the latch assembly from the lock lever 21, thereby detaching the first part 100a from the second part 100 b.

In one embodiment, the clip assembly includes a hanging plate 11 and a first elastic member 112. The hanging plate 11 is provided with a clamping hole 114 (see fig. 7). One end of the hanging plate 11 penetrates through the lock base 13 and is fixedly connected with the operating handle 12, and the first elastic member 112 abuts between the hanging plate 11 and the inner wall of the lock base 13 to provide a pretightening force for enabling the hanging plate 11 to have a moving trend towards the operating handle 12.

The top end of the lock rod 21 is provided with a clamping groove 210, when the top end of the lock rod 21 is inserted into the clamping hole 114 through the lock hole 1302, the hanging plate 11 can be clamped into the clamping groove 210 under the action of the first elastic piece 112, and therefore the clamping connection of the lock rod 21 and the hanging plate 11 is achieved.

Thus, when the handle is held by two hands and the index finger is used for pressing the abutting surface 212 at the bottom end of the lock rod 21, so that the lock rod 21 moves upwards, the top end of the lock rod 21 passes through the lock hole 1302 and then is inserted into the clamping hole 114 of the hanging plate 11, so that the hanging plate 11 is clamped into the clamping groove 210 of the lock rod 21, the clamping connection between the male lock 20 and the female lock 10 is realized, and the second part 100b is hung on the first part 100 a. At this time, even if the handle 30 is released, the second member 100b does not fall, so that the male lock 20 can be further operated to lock and fix the first member 100a and the second member 100 b.

When the operating handle 12 is pressed, the hanging plate 11 can compress the first elastic member 112 to move under the action of the pressing force, so that the hanging plate 11 is separated from the lock rod 21, and the first part 100a and the second part 100b are detached.

Alternatively, the first elastic member 112 may be a spring. In one embodiment, in order to ensure the stability of the motion of the peg board 11, a plurality of first elastic members 112 may be arranged side by side. In the embodiment shown in fig. 7, two first elastic members 112 are arranged side by side.

In one embodiment, the clamping assembly further includes a top sleeve 14 and a second elastic member 15.

The top sleeve 14 is movably installed in the cavity of the lock base 13 in the up-down direction and is located above the hanging plate 11. The second elastic element 15 is arranged between the top sleeve 14 and the top wall of the inner cavity to provide a pre-tightening force for enabling the top sleeve 14 to have a moving trend towards the hanging plate 11. One side of the top sleeve 14 facing the hanging plate 11 is provided with a limiting part 140, and the limiting part 140 can be inserted into the clamping hole 114 to limit the hanging plate 110, so that the lock rod 21 can be inserted into the clamping hole 114. Therefore, when the operating handle 12 is not pressed, the top sleeve 14 abuts against the hanging plate 11 under the elastic force of the second elastic piece 15, so that the limiting portion 140 is inserted into the clamping hole 114, the hanging plate 11 is positioned, the clamping hole 114 is ensured to correspond to the lock hole 1302, and the lock rod 21 can be inserted into the clamping hole 114 to realize clamping.

So, when needs realize the joint of locking lever 21 and link plate 11, and utilize the forefinger to press the face 212 of holding of supporting of locking lever 21 bottom, locking lever 21 upward movement inserts joint hole 114 when with the upward jacking of cover jacking 14 for spacing portion 140 deviates from joint hole 114, and link plate 11 blocks into draw-in groove 210 under the elastic force effect of first elastic component 112 this moment, thereby realizes that locking lever 21 is connected with the joint of link plate 11.

When needs realize locking lever 21 and link plate 11 and break away from, both hands grip the handle (prevent that locking lever 21 and joint spare 11 from breaking away from the back, second part 100b drops), and utilize the thumb to press handle 12, make link plate 11 deviate from draw-in groove 210, locking lever 21 moves down and breaks away from female lock 10 under the effect of gravity, and the while top cover 14 moves down under the elastic force of second elastic component 15, makes spacing portion 140 insert the joint hole, in order to carry on spacingly to link plate 11.

Specifically, in the embodiment, the lock base 13 includes a base 130 and an upper cover 132, the base 130 is fixedly installed on the first component 100a, the upper cover 132 is fixedly installed on the base 130 and encloses with the base 130 to form the inner cavity, and the lock hole 1302 is opened on the base 130.

Referring to fig. 1 to 4, in the embodiment of the present invention, the handle 30 includes a mounting portion 32 and a holding portion 34. The mounting portion 32 is fixedly connected to the second member 100b, and a mounting position 320 (see fig. 4) for mounting the male latch 20 is defined on the second member 100 b. The holding portion 34 is fixedly connected to one side of the mounting portion 32 and extends downward for easy holding.

Fig. 8 shows an exploded structure of a male lock of the locking mechanism shown in fig. 1. Fig. 9 shows a top view of the shank of the male lock shown in fig. 8. Figure 10 shows a cross-sectional view of the shank of the male lock shown in figure 8.

Referring to fig. 5-10, in some embodiments, the male lock 20 further includes a handle 23 (see fig. 8) and a locking sleeve 22. The lock lever 23 is rotatably attached to the second member 100b about the axis of the lock lever 21. The locking sleeve 22 is sleeved on the lock rod 21 and is in threaded connection with the lock rod 21, and the locking sleeve 22 and the lock handle 23 can rotate synchronously. The lock lever 23 is rotated to move the lock lever 21 along its axis (i.e., up and down direction) to lock or unlock the first member 100a and the second member 100 b.

The mounting portion 32 has an opening 322 (see fig. 2 and 4) above the holding portion 34, and the lock handle 23 extends from the opening 322 and is operable to rotate around the lock rod 21 in the opening 322, thereby moving the lock rod 21 up and down along the axis to lock or unlock the first component 100a and the second component 100 b.

When assembling the first and

second parts

100a and 100b, the handle 30 can be held by both hands, and the second part 100b is lifted so that the male lock 20 is aligned with and held by the female lock 10. Then, the pressing surface 212 at the bottom end of the lock rod 21 is pressed by the index finger, so that the lock rod 21 moves upwards and is inserted into the clamping hole 114, and is clamped with the hanging plate 11, thereby realizing that the second part 100b is hung on the first part 100 a. Then, the lock handle 23 is rotated by the thumb to drive the lock rod 21 to move downward to lock and fix the first component 100a and the second component 100 b.

When it is necessary to disassemble the first member 100a and the second member 100b, first, the lock lever 23 is unscrewed so that the first member 100a is loosened from the second member 100 b. Then, the handle 30 is held by both hands to lift the second member 100b, and the operating handle 12 of the female lock 10 is pressed by the thumb to disengage the lock lever 21 from the link plate 11, thereby separating the first member 100a from the second member 100 b.

Like this, the lock handle 23 is stretched out by opening 322 for lock handle 23 and the portion 34 of gripping are located the same one side of installation department 32, are convenient for rotate lock handle 23, and at this moment, the assembly and the dismantlement of first part 100a and second part 100b all only need an operating personnel can accomplish, and easy operation, swift.

It should be noted that in one embodiment, during rotation of lock handle 23, lock handle 23 includes a locked position and an unlocked position. When the lock handle 23 is pulled from the release position to the locking position, the lock sleeve 22 rotates to move the lock rod 21 downward relative to the lock sleeve 22, thereby locking the first member 100a and the second member 100 b. When the lock handle 23 is pulled from the locking position to the releasing position, the lock sleeve 22 rotates to drive the lock rod 21 to move upward relative to the lock sleeve 22, so as to release the first part 100a and the second part 100 b.

Alternatively, the internal thread of the locking sleeve 22 and the external thread of the locking rod 21 may adopt trapezoidal threads, thereby effectively preventing the connection between the locking sleeve 22 and the locking rod 21 from being loosened. It is understood that the internal thread of the locking sleeve 22 and the external thread of the locking rod 21 may be left-hand threads or right-hand threads, which is not limited herein.

In an embodiment, a third operation channel is provided between the holding portion 34 and the lock handle 23 for allowing a thumb to toggle the lock handle 23 to rotate when holding the holding portion 34. Thus, the lock handle 23 can be turned by the thumb to lock or unlock the first member 100a and the second member 100b while holding the grip portion of the handle with both hands, and the operation is convenient and quick.

In one embodiment, a rotating sleeve 230 is fixedly connected to one end of the lock handle 23. The rotating sleeve 230 is disposed outside the locking sleeve 22 and can rotate synchronously with the locking sleeve 22. In this way, the locking sleeve 22 can be driven to rotate around the axis of the locking rod 21 by rotating the locking handle 23, so as to drive the locking rod 21 to move in the up-and-down direction relative to the locking sleeve 22.

Referring to fig. 8, 9 and 10, in an embodiment, a strip-shaped groove 220 extending along an axis of the locking sleeve 22 is formed on an outer side wall of the locking sleeve 22, a limiting protrusion 2302 is convexly formed on an inner side wall of the rotating sleeve 230, and the limiting protrusion 2302 extends into the strip-shaped groove 220, so that the rotating sleeve 230 and the locking sleeve 22 can rotate synchronously. In this way, a synchronous rotation of the locking handle 23 and the locking sleeve 22 is achieved. Meanwhile, the bar-shaped groove 220 extending along the axis of the locking sleeve 22 is provided so that the restricting protrusion 2302 can move in the extending direction of the bar-shaped groove 220, that is, the locking sleeve 22 can move a certain distance in the direction along the axis of the locking rod 21 along with the locking rod 21. Namely, the pressing surface 212 at the bottom end of the lock rod 21 can be pressed by the forefinger, so that the lock rod 21 and the locking sleeve 22 move upwards together, and the lock rod 21 is clamped with the clamping piece 110. When the first part 100a and the second part 100b are disassembled, the lock bar 21 is separated from the clamping piece 110, and then the lock bar 21 and the locking sleeve 22 move downwards together under the action of self gravity, so that the lock bar 21 is separated from the lock hole 1302. More specifically, the upper end of the strip groove 220 is closed and the lower end is open. In this way, the upper end of the strip-shaped groove 220 is closed, thereby preventing the locking sleeve 22 from being released from the lower end of the rotating sleeve 230; the lower end of the strip-shaped groove 220 is open, so that the rotating sleeve 230 is sleeved outside the locking sleeve 22 from the lower end of the locking sleeve 22, and the assembly of the lock handle 23 and the locking sleeve 22 is realized. It will be appreciated that the locking lever 21, locking sleeve 22 and rotating sleeve 230 are coaxially disposed.
