Locking mechanism, hanging assembly and television hanging rack

Abstract

The utility model discloses a locking mechanism, a hanging assembly and a TV hanging rack, aims at solving the technical problem of single unlocking mode and low safety of the prior art. The locking mechanism comprises: a fixed plate with first and second guide channels; a to-be-mounted member with first and second matching parts; and a rotatable rotary lock body. During installation, the to-be-mounted member moves along the guide channel, and the first matching part drives the rotary lock body to rotate, so that a part of the rotary lock body blocks the second matching part, thereby automatically realizing locking. When unlocking, a preset operation sequence containing movement in the unlocking direction and the installation direction needs to be performed on the to-be-mounted member, so that the second matching part and the first matching part act on the rotary lock body in turn, and drive the rotary lock body to rotate to the unlocking position. The utility model is convenient to install, and the unique unlocking mode can effectively prevent accidental falling and has very high safety.

Description

Technical Field

[0001] This utility model relates to the field of mounting component technology, and in particular to a locking mechanism for a TV wall mount, a mounting component including the locking mechanism, and a TV wall mount. Background Technology

[0002] Television wall mounts are widely used in modern homes and commercial displays. They typically consist of a mounting plate fixed to the wall and a mounting bracket (stand) to be installed on the back of the television. For safety, once the mounting bracket is attached to the mounting plate, a reliable locking mechanism must be in place to prevent it from accidentally falling off.

[0003] Currently, a common TV wall mount locking mechanism on the market involves a slot on a mounting plate, where the component to be installed is screwed into the slot. To prevent the screw from accidentally slipping out of the slot, the mount has a locking mechanism controlled by a spring and a pull cord. During installation, the screw slides into the bottom of the slot, and the locking mechanism automatically blocks the screw's path under the action of the spring, thus locking it in place. During disassembly, the pull cord needs to be manually pulled to swing the locking mechanism to the unlocked position before the TV can be lifted and removed. While this structure achieves automatic locking, its unlocking process relies entirely on the pull cord, an external component. Not only is the pull cord hanging below the TV unsightly, but under accidental, upward impact, the single component of the locking mechanism bears the force. If the impact is large enough or the structural strength is insufficient, there is still a risk of it being forcibly pried open. Furthermore, the slot is usually a single, angled groove, which has limited stability in terms of load-bearing and guiding.

[0004] In summary, existing TV wall mount locking mechanisms suffer from limitations such as a single unlocking method and insufficient security. There is an urgent need for a novel locking mechanism that is ingeniously designed, easy to install, has a unique unlocking method, and offers extremely high security. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a locking mechanism, a hanging component and a TV wall mount, aiming to solve the technical problems of the existing locking mechanism having a single unlocking method, being easily unlocked by accident, and having low security.

[0006] To achieve the above objectives, this utility model provides a locking mechanism, comprising:

[0007] A fixing plate is provided with a first guide channel and a second guide channel extending along the installation direction. The first guide channel is used for a first mating part on a component to be installed to enter and move along the installation direction, and the second guide channel is used for a second mating part on the component to be installed to enter and move along the installation direction.

[0008] A rotary lock body is rotatably mounted on the fixed plate for selective contact with the first mating part and the second mating part;

[0009] Furthermore, the rotary lock body, the first mating part, and the second mating part are configured in a cooperative manner as follows:

[0010] In response to the movement of the component to be installed along the installation direction, the first mating part drives the rotary lock body to rotate, so that a portion of the rotary lock body blocks the movement of the second mating part along the unlocking direction opposite to the installation direction, thereby locking the component to be installed;

[0011] In response to performing a preset unlocking sequence on the locked component to be installed, the second mating part and the first mating part act sequentially with the rotary lock body to drive the rotary lock body to the unlock position, thereby simultaneously releasing the first mating part and the second mating part.

[0012] Preferably, the preset unlocking operation sequence is a continuous operation, which includes at least one movement along the unlocking direction and one movement along the installation direction.

[0013] Preferably, the rotary lock body has a first engagement portion and a second engagement portion;

[0014] The first engagement portion is configured to contact the first mating portion when the component to be installed moves along the installation direction to drive the rotary lock body to rotate to a locked position, in which the second engagement portion is located on the unlocking direction path of the second mating portion;

[0015] The second engagement portion is configured to contact the second mating portion when the mounting member moves along the unlocking direction in the unlocking operation sequence, so as to drive the rotary lock body to rotate to a preset position, in which the first engagement portion is not on the mounting direction path of the first mating portion, so that when the mounting member moves along the mounting direction in the unlocking operation sequence, the first mating portion can drive the rotary lock body to rotate to the unlock position.

[0016] Preferably, the structure of the first and second joints is configured as a joint structure capable of selectively engaging with the first and second mating parts, wherein the joint structure includes at least a notch or a protrusion.

[0017] This utility model also provides a mounting component, including:

[0018] The component to be installed has a first mating part and a second mating part; and

[0019] Any of the locking mechanisms described above.

[0020] Preferably, the component to be installed also has a mounting part, and the fixing plate has a receiving part for the mounting part to be mounted.

[0021] Preferably, in the preset installation posture of the component to be installed, the position of the second mating part is lower than the position of the first mating part; the entrances of the first guide channel and the second guide channel are coordinated to allow the first mating part and the second mating part to enter the corresponding guide channel without interference during the initial stage of installation; and the path length of the second guide channel along the installation direction is greater than that of the first guide channel.

[0022] Preferably, the first guide channel and the second guide channel are slot structures formed on the fixing plate, and the first mating part and the second mating part are both protrusion structures on the surface of the part to be installed.

[0023] This utility model further provides a television wall mount, characterized in that it includes any of the aforementioned mounting components, wherein the component to be installed is a bracket for supporting a television.

[0024] Compared with the prior art, the present invention, through the above technical solution, has at least the following beneficial effects:

[0025] 1. During installation, the user simply hangs the component to be installed (TV bracket) and slides it down into place along two independent straight guide channels. The first mating part will automatically drive the rotating lock body, which rotates in place, to lock the device. No tools or additional parts such as ropes are required throughout the process, greatly simplifying the installation procedure and improving efficiency and user experience.

[0026] 2. Unlike existing technologies that can be unlocked by pulling a rope in one direction, this invention requires a pre-set sequence of operations that includes at least one upward and one downward movement to unlock. This means that accidental, one-way impact or lifting forces cannot unlock it, fundamentally eliminating the risk of accidental detachment. Compared to simple spring-pulled rope locking devices, safety is significantly improved. Attached Figure Description

Detailed Implementation

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] This specification and accompanying drawings are merely illustrative examples of this application and are intended to cover any and all modifications, variations, combinations, or equivalents within the scope of this application. Clearly, those skilled in the art can make various alterations and modifications to this application without departing from its scope. Therefore, if such modifications and modifications fall within the scope of this application and its equivalents, this application intends to include such modifications and modifications.

[0036] This embodiment provides a mounting assembly for a television wall mount, which includes a locking mechanism. For example... Figure 1 and Figure 6 As shown, the mounting assembly mainly includes a fixing plate 10 fixed to a mounting surface such as a wall and a mounting component 30 for supporting the television. To ensure load-bearing capacity and structural stability, the fixing plate 10 and the mounting component 30 are usually made of high-strength metal materials, such as cold-rolled steel plates that are integrally stamped and formed, and the surface can be treated with anti-rust treatment such as powder coating.

[0037] Please see Figure 1 and Figure 6 The fixed plate 10 is equipped with a locking mechanism, which includes a first guide channel 11 and a second guide channel 12 formed on the fixed plate 10, and a rotary lock body 20 rotatably mounted on the fixed plate 10. Both the first guide channel 11 and the second guide channel 12 are slotted structures formed on the fixed plate 10. As can be seen from the accompanying drawings, the rotary lock body 20 is mounted on the fixed plate 10 via a shaft (e.g., a screw or rivet), allowing it to rotate freely.

[0038] The rotary lock body 20 has a first engaging portion 21 and a second engaging portion 22 for interacting with corresponding components on the part to be installed 30. In this embodiment, the first engaging portion 21 and the second engaging portion 22 are configured with notches. A clever feature of this notch structure is that it allows for a precise interference fit with the corresponding mating parts, serving a positioning function.

[0039] In addition, the fixing plate 10 also has a receiving part 13 for supporting the part 30 to be installed. Preferably, there are two receiving parts 13, which are located on both sides of the fixing plate 10 respectively, forming a stable two-point support.

[0040] The component to be installed 30, such as a television bracket, has multiple structures on its surface that mate with a locking mechanism. Specifically, it includes a first mating part 31, a second mating part 32, and a hooking part 33. In a preferred embodiment, these mating parts and hooking parts are integrally formed by cutting and stamping a metal sheet as the base material. For example, the first mating part 31 and the second mating part 32 are protruding structures formed by cutting and bending, while the hooking part 33 is a hook structure formed by cutting and stamping. This integral molding manufacturing method not only simplifies the production process and reduces costs, but more importantly, it ensures the structural strength of the component and the overall reliability.

[0041] In the preset installation posture of the component to be installed 30, the position of the second mating part 32 is lower than the position of the first mating part 31. To ensure smooth installation, the entrance positions of the first guide channel 11 and the second guide channel 12 are coordinated to allow the first mating part 31 and the second mating part 32 to enter their respective guide channels without interference at the initial stage of installation. Simultaneously, the path length of the second guide channel 12 along the installation direction is greater than that of the first guide channel 11. Preferably, there are two hooking parts 33, each corresponding to one of the two receiving parts 13.

[0042] The following is combined Figures 1 to 5 The installation, locking, and unlocking process of this embodiment is described in detail.

[0043] Installation and locking process (refer to) Figure 1 and Figure 2 ):

[0044] During installation, the user first aligns the two mounting parts 33 of the component to be installed 30 with the two receiving parts 13 of the fixing plate 10, respectively. At this time, the first mating part 31 is aligned with the entrance of the first guide channel 11, and the second mating part 32 is aligned with the entrance of the second guide channel 12, as in the initial state. Figure 1 As shown.

[0045] Subsequently, the user moves the component to be installed 30 along the installation direction (usually the direction of gravity, i.e., downward). The first mating part 31 enters the first guide channel 11, and the second mating part 32 enters the second guide channel 12. As the component to be installed 30 slides downward, the first mating part 31 on it contacts the first engagement part 21 of the rotary lock body 20, driving the rotary lock body 20 to rotate around its axis.

[0046] When the component to be installed 30 slides to the installation endpoint, it is in the locked state. Figure 2 As shown, the component to be installed 30 is hooked onto the receiving part 13 of the fixing plate 10 via the hook part 33, while the rotary lock body 20 is driven to the locked position. At this time, the first mating part 31 is precisely embedded in the notch of the first engaging part 21. The first engaging part 21 and the first mating part 31 are in an interference-locked state, allowing the rotary lock body 20 to be accurately positioned at the locked position angle without over-rotating due to inertia. Simultaneously, the second engaging part 22 of the rotary lock body 20 has rotated to the position of the second guide channel 12 and is located on the moving path of the second mating part 32 along the unlocking direction (i.e., upward), thus effectively blocking the second mating part 32. Thus, the component to be installed 30 is automatically and accurately locked onto the fixing plate 10. The installation process requires no additional tools, making it convenient and reliable.

[0047] Unlocking process (refer to) Figure 2 , Figure 3 , Figure 4 and Figure 5 ):

[0048] The unlocking process of this invention requires the execution of a preset continuous operation sequence, which includes at least one upward (unlocking direction) movement and one downward (installation direction) movement, greatly improving security.

[0049] 1. First step: Move upwards. From Figure 2 The locked state is initiated, and the user needs to move the component 30 to be installed upwards (along the unlocking direction). At this time, the locked second mating part 32 will move upwards and contact the second engagement part 22 of the rotary lock body 20. This force will drive the rotary lock body 20 to continue rotating to a preset intermediate position, such as... Figure 3 As shown. In this intermediate position, the second mating part 32 will form an interference jam with the notch of the second joint part 22, so that the rotary lock body 20 is accurately positioned at this intermediate angle, ensuring the smooth progress of subsequent operations. In this intermediate position, the first joint part 21 of the rotary lock body 20 has rotated and is no longer located on the path of the first mating part 31 along the installation direction (downward).

[0050] 2. Second step: Moving downwards. Next, the user needs to perform the second movement in the unlocking sequence, that is, moving the part to be installed 30 downwards along the installation direction. Since the first engaging part 21 is no longer on the original path of the first mating part 31, the first mating part 31 can now contact other parts of the rotary lock body 20, thereby driving the rotary lock body 20 to rotate further to the final unlocked position, such as... Figure 4 As shown.

[0051] 3. Third step: Unlock and remove. When the rotating lock body 20 is rotated to... Figure 4 When the device is in the unlocked position as shown, both the first engagement portion 21 and the second engagement portion 22 have completely cleared the movement path of the first mating portion 31 and the second mating portion 32. At this time, as... Figure 5 As shown, neither the first mating part 31 nor the second mating part 32 is interfered with. The user can smoothly lift the part to be installed 30 completely along the unlocking direction (upward) and remove it from the fixing plate 10 to complete the unlocking and disassembly.

[0052] In summary, this invention achieves automatic locking during installation and a unique "up-down" operation sequence during unlocking through the coordinated action of the first mating part 31, the second mating part 32, and the first engaging part 21 and the second engaging part 22 on the rotary lock body 20. This design not only simplifies the installation process, but more importantly, it effectively resists accidental impacts from a single direction, fundamentally preventing the risk of the television set accidentally falling off, thus providing extremely high safety.

[0053] As an alternative implementation, the unlocking sequence can also be designed to be more complex, for example, including multiple reverse movements (such as "up-down-up"). By adjusting the shape and position of the upper engagement part of the rotary lock body 20, more diverse unlocking sequences can be achieved to meet higher security requirements in different scenarios.
