[0030] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] See also Figures 1 to 10As shown, this utility model provides a locking component 100, which includes: a base 10; a locking member 20 having a locked position and an unlocked position, the locking member 20 being movably disposed relative to the base 10 along a first direction to switch between the locked position and the unlocked position; and an operating part 30 having an operating state and an anti-accidental contact state, wherein when the operating part 30 is in the operating state, the operating part 30 can drive the locking member 20 to move along the first direction, and when the operating part 30 is in the anti-accidental contact state, the locking member 20 remains in the current position.

[0032] In this embodiment, the locking component 100 can be installed on a display device mounting bracket that enables height adjustment in the prior art. When the locking component 20 is in the locked position, it can lock the display device (e.g., a television) at the required height. When the locking component 20 is in the unlocked position, it can adjust the height of the display device.

[0033] When the operation unit 30 is in operation, the operation unit 30 can drive the locking member 20 to move along the first direction, thereby realizing the switching of the locking member 20 between the locked position and the unlocked position. At this time, the user can adjust the height of the display device as needed, and after adjusting to the ideal height, the locking member 20 can be locked to keep the display device at the ideal height position. When the operating unit 30 is in the anti-accidental contact state, the operating unit 30 cannot drive the locking member 20 to move along the first direction. At this time, the locking member 20 cannot switch between the locked position and the unlocked position. The locking member 20 remains in the current position. That is, when the operating unit 30 is in the anti-accidental contact state, if the locking member 20 is in the unlocked position, then the locking member 20 will remain in the unlocked position and cannot switch to the unlocked position. If the locking member 20 is in the locked position, then the locking member 20 will remain in the locked position. Even if a person or object accidentally touches the operating unit 30, the locking member 20 will not be affected and will not switch to the unlocked position. This can prevent accidental contact by personnel from causing the locking member 20 to switch to the unlocked position and threatening personal safety. This can solve the problem that the locking structure in the prior art is prone to safety hazards caused by accidental contact by personnel.

[0034] As can be seen from the above, the locking component 100 of this application can ensure that the locking component 20 will not be accidentally unlocked due to accidental contact. Even when facing children or users unfamiliar with the device, this anti-accidental contact state can effectively prevent accidental operation and improve the overall safety and reliability of the system.

[0035] See also Figures 1 to 10As shown, in one embodiment of the present invention, the operating part 30 is rotatably and movable along the first direction relative to the base 10. The locking assembly further includes a connecting structure 40, the first end of which is connected to the locking member 20. The connecting structure 40 is rotatably and movable along the first direction relative to the base 10. When the operating part 30 is in the operating state, the operating part 30 rotates and drives the connecting structure 40 to rotate, so that the connecting structure 40 drives the locking member 20 to move along the first direction. When the operating part 30 is in the anti-accidental contact state, the operating part 30 releases the transmission cooperation with the connecting structure 40.

[0036] In this embodiment, when the operating unit 30 is in the operating state, it can form a transmission engagement with the connecting structure 40. Rotating the operating unit 30 can drive the connecting structure 40 to rotate and move it along the first direction, thereby causing the connecting structure 40 to drive the locking member 20 to move along the first direction, thus switching the locking member 20 between the locked and unlocked positions. However, when the operating unit 30 is in the anti-accidental contact state, the operating unit 30 is disengaged from the connecting structure 40. At this time, even if the operating unit 30 is rotated, it cannot drive the connecting structure 40 to rotate. The connecting structure 40 cannot move relative to the base 10 along the first direction, nor can it drive the locking member 20 to move along the first direction, thus preventing the switching of the locking member 20 between the locked and unlocked positions.

[0037] In one embodiment, the first end of the connecting structure 40 is threaded into the base 10, and the second end of the connecting structure 40 is provided with a slot. The operating part 30 is movably disposed relative to the connecting structure 40 along the second direction. The operating part 30 is provided with a protrusion that can engage with the slot. The operating part 30 is moved along the second direction until the protrusion is engaged in the slot. Then, rotating the operating part 30 can drive the connecting structure 40 to rotate, thereby enabling the connecting structure 40 to drive the locking member to move along the first direction.

[0038] See also Figures 1 to 10 As shown, in one embodiment of the present invention, the operating part 30 is provided with a first mating structure, and the second end of the connecting structure 40 is provided with a second mating structure. When the operating part 30 is in the operating state, the first mating structure and the second mating structure are in transmission mating.

[0039] In this embodiment, when the operating unit 30 is in the operating state, the transmission engagement between the first and second mating structures enables the operating unit 30 to drive the connecting structure 40 to move along the first direction, thereby enabling the connecting structure 40 to drive the locking member 20 to move along the first direction, thus switching the locking member 20 between the locked and unlocked positions. However, when the operating unit 30 is in the anti-accidental contact state, the first and second mating structures cannot achieve transmission engagement. At this time, the connecting structure 40 cannot move relative to the base 10 along the first direction, nor can it drive the locking member 20 to move along the first direction, thus preventing the switching of the locking member 20 between the locked and unlocked positions.

[0040] See also Figures 1 to 10 As shown, in one embodiment of the present invention, the first mating structure includes a first annular rack 50, and the second mating structure includes a second annular rack 60. When the operating part 30 is in the operating state, the first annular rack 50 and the second annular rack 60 mesh.

[0041] In this embodiment, the user moves the operating part 30 along the first direction toward the connecting structure 40 by a specific action (e.g., pressing) until the first annular rack 50 engages with the second annular rack 60. At this time, the operating part 30 is in the operating state. The user continues to rotate the operating part 30, which can drive the connecting structure 40 to rotate synchronously, so that the connecting structure 40 moves along the first direction, and finally drives the locking member 20 to move along the first direction.

[0042] When the operating part 30 is in the anti-accidental contact state, the first annular rack 50 and the second annular rack 60 are separated. At this time, rotating the operating part 30 will not cause the connecting structure 40 to rotate synchronously. As can be seen from the above, the switching between the locking and unlocking positions of the locking member in this application is divided into two steps. It is necessary to press the operating part 30 in the first direction to make the first annular rack 50 and the second annular rack 60 engage, and at the same time rotate the operating part 30 to achieve this, thereby preventing accidental contact that would cause the locking member 20 to switch to the unlocking position.

[0043] See also Figures 1 to 10 As shown, in one embodiment of the present invention, the locking component 100 further includes an elastic element 70, which elastically abuts between the connecting structure 40 and the operating part 30. The elastic element 70 can provide an elastic force to separate the first mating structure from the second mating structure.

[0044] In this embodiment, when the first mating structure and the second mating structure are engaged in transmission, the elastic element 70 is compressed. When the force that keeps the first mating structure and the second mating structure engaged in transmission is removed, the first mating structure and the second mating structure separate under the action of the elastic restoring force of the elastic element 70, so that the operating part 30 can automatically switch to the anti-accidental contact state without the need for an additional mechanical reset mechanism, which simplifies the structure and reduces costs.

[0045] In one embodiment, the elastic element 70 is a compression spring.

[0046] See also Figures 1 to 10 As shown, in one embodiment of the present invention, one of the connecting structure 40 and the operating part 30 is provided with a mounting groove 41 extending in the first direction, and the other of the connecting structure 40 and the operating part 30 is provided with a guide rod 31 extending in the first direction. The mounting groove 41 and the guide rod 31 are provided correspondingly. One end of the elastic member 70 abuts against the bottom wall of the mounting groove 41, and the other end of the elastic member 70 is sleeved on the guide rod 31.

[0047] The above configuration enables the installation of the elastic element 70, and by setting the mounting groove 41 and guide rod 31 within a limited space, it reduces the occupation of external space, achieves a compact layout of the structure, and facilitates the miniaturization of the locking component 100.

[0048] See also Figures 1 to 10 As shown, in one embodiment of the present invention, the operating part 30 has a receiving cavity 32, and a slide groove 33 extending in a first direction is provided in the receiving cavity 32. The locking assembly 100 also includes a limiting structure. The end of the connecting structure 40 away from the locking member 20 is slidably disposed in the slide groove 33. The limiting structure is disposed in the receiving cavity 32 and located at the opening end of the slide groove 33 to limit the second end of the connecting structure 40 in the slide groove 33. The first mating structure and the second mating structure are both located in the slide groove 33.

[0049] In this embodiment, the combination of the slide groove 33 and the limiting structure ensures the precise sliding and positioning of the second end of the connecting structure 40 in the first direction, thereby improving the accuracy of the engagement between the first and second mating structures. The limiting structure prevents the second end of the connecting structure 40 from dislodging from the slide groove 33. The slide groove 33 simplifies the assembly process of the locking assembly 100; the connecting structure 40 only needs to be slid into the slide groove 33 and fixed by the limiting structure. Similarly, maintenance and adjustment become more convenient, eliminating the need for complex disassembly and reassembly steps. In addition, placing the first and second mating structures within the slide groove 33 reduces exposed parts and improves the aesthetic appearance.

[0050] See also Figures 1 to 10As shown, in one embodiment of the present invention, the limiting structure includes a baffle 80, which is fixedly installed in the receiving cavity 32. The baffle 80 is provided with a first through hole 81 for the first end of the connecting structure 40 to pass through. The side of the baffle 80 away from the locking member 20 can limit the second end of the connecting structure 40 in the slide groove 33.

[0051] In this embodiment, the first through hole 81 on the baffle 80 allows the first end of the connecting structure 40 to pass through, so as to connect the first end of the connecting structure 40 to the locking member 20. The side of the baffle 80 away from the locking member 20 can limit the second end of the connecting structure 40 within the slide groove 33, preventing the connecting structure 40 from accidentally coming out of the slide groove 33 during movement. During maintenance, the components in the slide groove 33 can be easily inspected or replaced simply by removing the baffle 80, improving maintenance efficiency.

[0052] In one embodiment, the limiting structure can also be a snap-fit ​​structure to prevent the second end of the connecting structure 40 from coming out of the slide groove 33.

[0053] See also Figures 1 to 10 As shown, in one embodiment of the present invention, the locking assembly 100 further includes a first rack 90 extending in a second direction, and a second rack 21 extending in a second direction is provided on the side of the locking member 20 opposite to the operating part 30. The first rack 90 is configured to be mounted on the movable part of the liftable mounting bracket, and the second rack 21 is correspondingly provided with the first rack 90. ​​When the locking member 20 is in the locked position, the first rack 90 and the second rack 21 are engaged. When the locking member 20 is in the unlocked position, the first rack 90 and the second rack 21 are disengaged.

[0054] In this embodiment, the movable part of the height-adjustable mounting bracket can move along a second direction. A display device (e.g., a television) is mounted on the movable part and can move along the second direction with the movable part, thus adjusting the position of the display device. The first rack 90 extends along the second direction, ensuring that it can engage with the second rack 21 during the movement of the movable part in the second direction, restricting the movement of the movable part in the second direction. At this time, the locking member 20 is in the locked position, causing the display device to stop at the desired position, thereby achieving height locking of the height-adjustable mounting bracket. When the locking member 20 is in the unlocked position, the first rack 90 disengages from the second rack 21. At this time, the movable part can move freely along the second direction to achieve height adjustment of the display device.

[0055] See also Figures 1 to 10As shown, in one embodiment of the present invention, the locking component 100 further includes a locking member 204. The locking member 20 is provided with a groove 23 and a second through hole 22 communicating with the groove 23. The first end of the connecting structure 40 includes a threaded section 42 and a smooth rod section 43. The threaded section 42 is threadedly engaged with the base 10. The smooth rod section 43 passes through the second through hole 22 and can rotate relative to the second through hole 22. The locking member 204 is locked at the end of the smooth rod section 43 away from the operating part 30 and forms a stop and limit on the locking member 20 in the first direction.

[0056] In this embodiment, the base 10 is configured to be fixedly connected to the fixing part of the liftable mounting bracket. The base 10 is stationary. Through the threaded engagement of the threaded section 42 with the base 10, when the connecting structure 40 rotates relative to the base 10, the connecting structure 40 can move relative to the base 10 in the first direction. The end face of the threaded section 42 away from the operating part 30 forms a stepped structure with the smooth rod section 43. The stepped structure cooperates with the end of the locking member 204 away from the operating part 30 to limit the locking member 20 in the first direction, preventing the locking member 20 from disengaging from the smooth rod section 43, and also preventing the locking member 20 from sliding on the smooth rod section 43 in the first direction.

[0057] In one embodiment, the locking device 204 is a screw.

[0058] See also Figures 1 to 10 As shown, in one embodiment of the present invention, the base 10 has a mounting cavity 11, and the locking member 20 is movably disposed in the mounting cavity 11 along a first direction.

[0059] In this embodiment, the mounting cavity 11 restricts the movement trajectory of the locking member 20 to the mounting cavity 11 of the base 10, which not only achieves a compact layout of the locking assembly 100 and saves external space, but also protects the locking member 20 and extends its service life.

[0060] See also Figures 1 to 10 As shown in one embodiment of the present invention, an annular plate 44 is provided at the second end of the connecting structure 40, and a second annular rack 60 is installed on the side of the annular plate 44 away from the locking member 20. A plurality of protrusions 45 are provided on the side of the annular plate 44 facing the baffle 80, and the plurality of protrusions 45 are spaced apart circumferentially along the annular plate 44. This arrangement reduces the friction between the baffle 80 and the connecting structure 40.

[0061] In one embodiment of this utility model, a plurality of protrusions 45 are provided on the side of the baffle 80 facing the connecting structure 40, and the plurality of protrusions 45 are spaced apart along the circumference of the baffle 80. This arrangement reduces the friction between the baffle 80 and the connecting structure 40.

[0062] See also Figures 1 to 10 As shown, in one embodiment of this utility model, the baffle 80 is provided with at least two first connecting holes 82, which are spaced apart circumferentially along the baffle 80. The receiving cavity 32 of the operating part 30 is provided with at least two pillars, each pillar having a second connecting hole 35. The locking assembly 100 further includes at least two connectors 206. The at least two first connecting holes 82 and at least two second connecting holes 35 are correspondingly arranged, and a connector 206 passes through the corresponding first connecting hole 82 and second connecting hole 35. Through the above arrangement, the baffle 80 can be installed.

[0063] See also Figures 1 to 10 As shown, in one embodiment of this utility model, a plurality of reinforcing ribs 34 are further provided inside the receiving cavity 32. The plurality of reinforcing ribs 34 are arranged at intervals along the circumference of the sliding groove 33. One end of the reinforcing rib 34 is connected to the inner wall of the receiving cavity 32, and the other end of the reinforcing rib 34 is connected to the outer wall of the sliding groove 33. Through the above arrangement, the structural strength of the operating part 30 can be enhanced.

[0064] In one embodiment, one of the first and second mating structures is a protrusion, and the other is a groove, with the protrusion and groove engaging in a mating fit. It should be noted that the groove here does not refer to a groove 23 on the locking member 20, but rather to a groove in the prior art, not limited to square grooves, cylindrical grooves, etc.

[0065] See also Figures 1 to 10 As shown, this utility model provides a liftable mounting bracket, including: the locking component 100 as described above.

A connector 206 is inserted into the corresponding third connecting hole 131 and the fourth connecting hole to realize the fixed connection between the base 10 and the outer tube 202.

[0070] Multiple pulleys 203 are fixedly installed at the top and bottom of the outer tube 202. The multiple pulleys 203 located at the top and bottom of the outer tube 202 are arranged along the circumference of the outer tube 202. The pulleys 203 roll in contact with the outer wall surface of the inner tube 201. This arrangement can reduce the frictional force when the inner tube 201 slides relative to the outer tube 202 in the second direction, making the sliding smoother. At the same time, it can also make the inner tube 201 slide relative to the outer tube 202 with basically no shaking.

[0071] In one embodiment, the connector 206 is a bolt or screw.

[0072] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: A base, a locking element, and an operating unit are provided. When the operating unit is in the operating state, it can drive the locking element to move along a first direction, thereby switching the locking element between the locked and unlocked positions. At this time, the user can adjust the height of the display device as needed, and after adjusting to the ideal height, the locking element can be locked to maintain the display device at the ideal height. When the operating unit is in the anti-accidental-touching state, it cannot drive the locking element to move along the first direction. Therefore, it cannot switch the locking element between the locked and unlocked positions, and the locking element remains in its current position. This ensures that the locking element will not be accidentally unlocked due to accidental contact. Even when facing children or users unfamiliar with the device, this anti-accidental-touching state can effectively prevent accidental operation, thereby solving the problem that the locking structure in the prior art is prone to safety hazards caused by accidental contact.
