Abstract

The utility model is suitable for the technical field of supports, and provides a mounting frame which comprises a first mounting structure, a second mounting structure and a limiting structure. During use, to-be-mounted equipment is mounted on the first mounting structure, and the second mounting structure is mounted at the mounting position. A user can apply force to rotate the first support so as to drive the second transmission part to rotate by a certain angle. The second limiting parts on the second transmission piece can be alternately matched with the multiple first limiting parts of the limiting structure in a concave-convex mode, or the first limiting parts of the limiting structure can be alternately matched with the multiple second limiting parts on the second transmission piece in a concave-convex mode. After external force applied to the first support is removed, due to concave-convex matching of the first limiting part and the second limiting part, rotation of the second transmission piece relative to the limiting structure can be hindered, the first support is not prone to rotating relative to the second mounting structure, and the situation that equipment to be mounted instantly turns over under the action of gravity is avoided as much as possible; and the damage risk of the to-be-installed equipment is reduced.

Description

Technical Field

In the related art, the mounting bracket includes a bracket, a mounting structure, and a locking nut. The device to be installed is installed on the bracket, and the mounting structure is installed on the installation position. The user can tighten the locking nut to fix the bracket on the mounting structure, or the user can loosen the locking nut so that the bracket and the mounting structure can rotate relative to each other to adjust the use angle of the device to be installed.

[0044] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0045] It should be noted that the mounting bracket provided in the embodiments of the present application is used to mount a device to be mounted on a mounting location. The device to be mounted may be a television, tablet, or other device. The mounting location may be a desktop, a wall, or a ceiling. The following description assumes that the device to be mounted is a television and the mounting location is a wall.

[0046] See also Figures 1 to 4 The mounting frame includes a first mounting structure 10, a second mounting structure 20 and a limiting structure 40. The first mounting structure 10 includes a first bracket 11 and a first transmission member 12, and the first transmission member 12 is arranged on the first bracket 11. The second mounting structure 20 is rotatably connected to the first bracket 11. The second transmission member 30 is rotatably connected to the second mounting structure 20. The second transmission member 30 is also engaged with the first transmission member 12. The limiting structure 40 is arranged on the second mounting structure 20. When the first bracket 11 rotates relative to the second mounting structure 20, the first transmission member 12 is used to drive the second transmission member 30 so that the second transmission member 30 rotates around the first axis L1 relative to the limiting structure 40 and the second mounting structure 20. On the first axis L1, a first limiting portion 41 is provided on the side of the limiting structure 40 close to the second transmission member 30, and a second limiting portion 31 is provided on the side of the second transmission member 30 close to the limiting structure 40.

[0047] It should be noted here that when the first bracket 11 rotates relative to the second mounting structure 20, the second transmission member 30 can rotate around the first axis L1 relative to the limiting structure 40 and the second mounting structure 20 under the drive of the first transmission member 12, so that the first bracket 11 can also rotate roughly around the first axis L1 relative to the second mounting structure 20 and the limiting structure 40.

[0048] The limiting structure 40 and the second mounting structure 20 may at least be anti-rotationally engaged, so that the second transmission member 30 can rotate relative to the limiting structure 40 .

[0049] As an example, the limiting structure 40 can be set to be fixedly installed on the second mounting structure 20, so that when the second transmission member 30 rotates, the limiting structure 40 will not rotate, thereby realizing the relative rotation of the limiting structure 40 and the second transmission member 30, and then realizing the rotation of the first bracket 11 relative to the second mounting structure 20.

[0050] As an example, the limiting structure 40 can also be set to be anti-rotationally engaged with the second mounting structure 20, but the limiting structure 40 can move on the second mounting structure 20 along the first axis L1. For details, please refer to the relevant description of the embodiment of setting the support structure 50 below.

[0051] The first limiting portion 41 and the second limiting portion 31 can be configured as a mating structure of a protrusion and a groove. The first limiting portion 41 can be shaped like a rectangle, a sphere, etc., and accordingly, the second limiting portion 31 can be configured to match the shape of the first limiting portion 41.

[0052] In one implementation, a plurality of first limiting portions 41 are provided, and the plurality of first limiting portions 41 are spaced apart along the circumferential direction. The second limiting portion 31 can alternately engage with the plurality of first limiting portions 41 in a concave-convex manner. It is understandable that the plurality of first limiting portions 41 are arranged circumferentially around the first axis L1, so that when the second transmission member 30 rotates around the first axis L1 driven by the first transmission member 12, the plurality of first limiting portions 41 on the limiting structure 40 can alternately engage with the second limiting portion 31 in a concave-convex manner. In this way, when the second transmission member 30 rotates around the first axis L1 relative to the second mounting structure 20, the second transmission member 30 also rotates relative to the limiting structure 40.

[0053] Alternatively, in another embodiment, a plurality of second limiting portions 31 are provided, and the plurality of second limiting portions 31 are spaced apart along the circumferential direction. The first limiting portion 41 can alternately engage with the plurality of second limiting portions 31 in a concave-convex manner. The second transmission member 30 can rotate about the first axis L1 driven by the first transmission member 12, and at this time, the first limiting portion 41 alternately engages with the plurality of second limiting portions 31 in a concave-convex manner. Based on this, the plurality of second limiting portions 31 spaced apart along the circumferential direction are arranged around the first axis L1.

[0054] Alternatively, in another embodiment, a plurality of first limiting portions 41 are provided, and the plurality of first limiting portions 41 are spaced apart along the circumferential direction. A plurality of second limiting portions 31 are also provided, and the plurality of second limiting portions 31 are spaced apart along the circumferential direction. Each second limiting portion 31 can alternately engage with the plurality of first limiting portions 41 in a concave-convex manner. Each first limiting portion 41 can also alternately engage with the plurality of second limiting portions 31 in a concave-convex manner. The plurality of second limiting portions 31 and the plurality of first limiting portions 41 are both arranged around the first axis L1.

[0055] It should also be noted that the concave-convex fit between the first limiting portion 41 and the second limiting portion 31 can achieve circumferential limitation of the second limiting portion 31 and the first limiting portion 41 around the first axis L1. However, when a user applies a rotational driving force to the first bracket 11, the first transmission member 12 can drive the second transmission member 30 to rotate, resulting in alternating concave-convex fit between the first limiting portion 41 and the second limiting portion 31. It can be understood that this degree of concave-convex fit allows the user to rotate under the application of external force, while achieving circumferential limitation around the first axis L1 without the application of external force, allowing the mounting bracket to achieve both rotational and position limitation when rotated to a certain angle.

[0056] As an example, the degree of depression of the concave structures in the first limiting portion 41 and the second limiting portion 31 is relatively small, so that the convex structure can not only achieve circumferential limitation with the above-mentioned concave structure around the first axis L1, but also can drive the convex structure and the concave structure to rotate relative to each other around the first axis L1 under external force.

[0057] As an example, at least one of the first limiting portion 41 and the second limiting portion 31 is elastic, so that the first limiting portion 41 and the second limiting portion 31 can achieve circumferential limitation around the first axis L1, and can also drive the elastic parts of the first limiting portion 41 and the second limiting portion 31 to undergo elastic deformation under external force, thereby allowing the first limiting portion 41 and the second limiting portion 31 to rotate relative to each other around the first axis L1.

[0058] Among them, the first axis L1 is as follows Figure 1 The axis L1 indicated in the figure, along the first axis L1 refers to the extension direction along the first axis L1, that is, along the length direction of the first axis L1.

[0059] When the first limiting portion 41 alternately engages with the plurality of second limiting portions 31 in a concave-convex manner, the user can set the number of second limiting portions 31 as needed. The greater the number of second limiting portions 31, the greater the angle to which the first bracket 11 can be rotated. In other words, the first bracket 11 has a greater number of adjustable angles, thereby improving the range of adjustable angles and the smoothness of adjustment for the first bracket 11. Similarly, when the second limiting portion 31 alternately engages with the plurality of first limiting portions 41 in a concave-convex manner, the greater the number of second limiting portions 31, the greater the number of adjustable angles for the first bracket 11.

[0060] The mounting bracket provided in the embodiment of the present application, when in use, can be used to mount the device to be mounted on the first mounting structure 10 and to install the second mounting structure 20 in the mounting position. A user can drive the first bracket 11 to rotate relative to the second mounting structure 20, and the first transmission member 12 can drive the second transmission member 30 to rotate about the first axis L1 relative to the retaining structure 40 and the second mounting structure 20. The user can apply force to rotate the first bracket 11 to rotate the second transmission member 30 by a certain angle. During this rotation, the second retaining portion 31 on the second transmission member 30 can alternately engage with the multiple first retaining portions 41 of the retaining structure 40, or the first retaining portion 41 of the retaining structure 40 can alternately engage with the multiple second retaining portions 31 on the second transmission member 30. Thus, after the external force on the first bracket 11 is removed, the relative rotation between the second transmission member 30 and the retaining structure 40 is hindered due to the concave-convex engagement between the first retaining portion 41 and the second retaining portion 31. The second transmission member 30 is not easy to rotate relative to the limiting structure 40, which makes the first transmission member 12 not easy to rotate, and the first bracket 11 is not easy to rotate further relative to the second installation structure 20, avoiding the instantaneous flipping of the equipment to be installed under the action of gravity, and reducing the risk of damage to the equipment to be installed.

[0061] Furthermore, compared to existing manual adjustment methods, the present invention's retaining structure 40 and second transmission member 30 maintain a consistent concave-convex fit during use, ensuring that the first bracket 11 and second mounting structure 20 consistently experience resistance during relative rotation. This eliminates the need for users to manually adjust the damping between the first bracket 11 and second mounting structure 20 by tightening a locking nut, making the present invention's mounting bracket adjustment method simpler, more labor-saving, and more efficient.

[0062] In some embodiments, see Figures 1 to 4 The limiting structure 40 includes a mounting assembly 42 and a first ball 43. The mounting assembly 42 is arranged on the second mounting structure 20. The mounting assembly 42 and the second transmission member 30 are distributed along the first axis L1. Along the first axis L1, a first groove 421 is provided on the side of the mounting assembly 42 close to the second transmission member 30. The second limiting portion 31 is provided with a second groove 311. The first ball 43 is limited in the first groove 421 and can roll in the first groove 421. The first limiting portion 41 is a portion of the first ball 43 that protrudes outside the first groove 421. The first limiting portion 41 is used to match the second groove 311 in a concave-convex manner.

[0063] It should be noted that, in order to ensure the installation stability of the first ball 43 in the first groove 421, the depth of the first groove 421 is generally set to be greater than the radius of the first ball 43, but less than the diameter of the first ball 43. The first ball 43 can partially protrude from the first groove 421 while being stably installed in the first groove 421. In this way, the first ball 43 is not easily separated from the first groove 421 during rotation.

[0064] In one implementation, the number of first balls 43 can be multiple, distributed around the first axis L1. The mounting assembly 42 is provided with multiple first grooves 421 distributed around the first axis L1, with each first ball 43 mounted in a corresponding first groove 421. In this case, the number of second grooves 311 can be multiple, distributed sequentially around the first axis L1, with the number of second grooves 311 exceeding the number of first grooves 421. In this way, the portion of each first ball 43 protruding from the first groove 421 can engage with the second groove 311 in a concave-convex manner.

[0065] Alternatively, in another implementation, the number of first ball 43 is set to one, and accordingly, the mounting assembly 42 may be provided with a first groove 421 to accommodate the first ball 43. In this case, the number of second grooves 311 may be multiple, and the multiple second grooves 311 are sequentially distributed around the first axis L1. In this way, the portion of the first ball 43 protruding from the first groove 421 can be able to mate with each second groove 311 in a concave-convex manner.

[0066] During use, the user can drive the first bracket 11 to rotate relative to the second mounting structure 20 by manually pulling or other means, and the first transmission member 12 can drive the second transmission member 30 to rotate around the first axis L1 relative to the limiting structure 40 and the second mounting structure 20. During the rotation process, the first ball 43 of the limiting structure 40 switches among the multiple second grooves 311. When the external force on the first bracket 11 is removed, due to the concave-convex fit of the first ball 43 and the second groove 311, the concave-convex fit of the first ball 43 and the second groove 311 can provide damping for the rotation of the first bracket 11 and the second mounting structure 20, thereby hindering the rotation of the first transmission member 12, and the first bracket 11 is not easy to rotate further relative to the second mounting structure 20, thereby avoiding the situation where the equipment to be installed is instantly flipped under the action of gravity as much as possible, and reducing the risk of damage to the equipment to be installed.

[0067] In some embodiments, the mounting bracket further includes a second ball bearing. A third groove is defined along the first axis L1 on the side of the second transmission member 30 proximate to the retaining structure 40. The first retaining portion 41 is defined by a fourth groove. The second ball bearing is retained within the third groove and is capable of rolling therein. The second retaining portion 31 is the portion of the second ball bearing that protrudes from the third groove. The second retaining portion 31 is configured to engage with the fourth groove in a concave-convex manner.

[0068] It should be noted that to ensure the stability of the second ball's installation within the third groove, the depth of the third groove is typically greater than the radius of the second ball but less than its diameter. This allows the second ball to partially protrude from the third groove while remaining stably mounted within it, preventing it from dislodging during rotation.

[0069] In one implementation, the number of second balls can be multiple, distributed around the first axis L1. The second transmission member 30 is provided with multiple third grooves distributed around the first axis L1, with each second ball mounted in a corresponding third groove. In this case, the number of fourth grooves can be multiple, distributed sequentially around the first axis L1, with the number of fourth grooves exceeding the number of third grooves. This ensures that the portion of each second ball protruding from the third groove can engage with the fourth groove.

[0070] Alternatively, in another embodiment, the number of second balls is set to one, and accordingly, a third groove can be provided on the second transmission member 30 to accommodate the second balls. The number of fourth grooves can be set to multiple, and the multiple fourth grooves are sequentially distributed around the first axis L1, so that the portion of the second ball protruding from the third groove can be mated with the fourth groove in a concave-convex manner.

[0071] During use, the user can drive the first bracket 11 to rotate relative to the second mounting structure 20 by manually pulling or other means, and the first transmission member 12 can drive the second transmission member 30 to rotate around the first axis L1 relative to the limiting structure 40 and the second mounting structure 20. During the rotation process, the second ball of the second transmission member 30 switches between multiple fourth grooves. When the external force on the first bracket 11 is removed, the concave-convex fit of the second ball and the fourth groove can provide damping for the rotation of the first bracket 11 and the second mounting structure 20, making it difficult for the second transmission member 30 to rotate relative to the limiting structure 40, thereby hindering the rotation of the first transmission member 12, and the first bracket 11 is not easy to rotate further relative to the second mounting structure 20, thereby improving the problem of damage caused by the instantaneous flipping of the equipment to be installed under the action of gravity.

[0072] In some embodiments, see Figures 2 to 5, the second mounting structure 20 includes a second bracket 21 and a connecting shaft 22. The connecting shaft 22 is arranged on the second bracket 21. The limiting structure 40 is provided on the connecting shaft 22. The first bracket 11 can be rotatably mounted on the connecting shaft 22 around the first axis L1. The second transmission member 30 can also be rotatably mounted on the connecting shaft 22 around the first axis L1. The second transmission member 30 is limited between the first bracket 11 and the limiting structure 40 along the first axis L1. In this embodiment, the first bracket 11 and the second bracket 21 are rotatably connected through the connecting shaft 22, and the connecting shaft 22 serves as the center of rotation.

[0073] In one possible design, the second bracket 21 and the connecting shaft 22 can be configured to be mutually fixed about the first axis L1, that is, they cannot rotate relative to each other about the first axis L1. For example, the through-hole of the second bracket 21 can be configured to have a non-circular shape, such as a single-cut circle, a double-cut circle, a square, or a hexagonal shape, and the cross-section of the connecting shaft 22 perpendicular to the axial direction can be configured to be non-circular. This ensures that when the connecting shaft 22 is inserted into the through-hole of the second bracket 21, the connecting shaft 22 and the second bracket 21 are mutually fixed.

[0074] In one possible design, the connecting shaft 22 can be fixedly mounted on the second bracket 21 by means of a nut, a retaining spring, or the like, so that the connecting shaft 22 is limited relative to the first bracket 11 and the second bracket 21 along the first axis L1, thereby preventing the connecting shaft 22 from axially moving relative to the first bracket 11 and the second bracket 21. In some other embodiments, the second bracket 21 and the connecting shaft 22 can be integrally formed.

[0075] The retaining structure 40 can be configured to prevent rotation with the connecting shaft 22 about the first axis L1, that is, the two cannot rotate relative to each other about the first axis L1. For example, the through-hole in the retaining structure 40 can be configured as a non-circular shape, and the cross-section of the connecting shaft 22 perpendicular to the axial direction can be configured as a non-circular shape. When the connecting shaft 22 is inserted into the through-hole of the retaining structure 40, the connecting shaft 22 and the retaining structure 40 can be prevented from rotating relative to each other.

[0076] By limiting the second transmission member 30, the travel of the second transmission member 30 along the first axis L1 is limited, thereby ensuring that the second limiting portion 31 on the second transmission member 30 can cooperate with the concave and convex part of the first limiting portion 41 on the limiting structure 40, thereby avoiding the first limiting portion 41 from separating from the second limiting portion 31 as much as possible, and improving the stability of the first bracket 11 when adjusting the use angle.

[0077] In some embodiments, the second mounting structure 20 includes a swing arm, which can be rotatably connected to the second bracket 21. At the same time, the swing arm can also be rotatably mounted on a mounting seat or other structure on the wall, and drive the TV mounted on the mounting bracket to rotate relative to the wall.

[0078] Alternatively, in other embodiments, see Figure 5 The second mounting structure 20 includes a second bracket 21 and a connecting shaft 22. The connecting shaft 22 is arranged on the second bracket 21. The limiting structure 40 is provided on the connecting shaft 22. The second transmission member 30 is rotatably mounted on the connecting shaft 22 around the first axis L1. The second transmission member 30 is limited between the first bracket 11 and the limiting structure 40 along the first axis L1. The first bracket 11 is rotatably connected to the second bracket 21 around the third axis L3, that is, in this embodiment, the third axis L3 is used as the rotation center of the first bracket 11. The first bracket 11 is provided with an arc groove 111 extending around the third axis L3. The connecting shaft 22 is inserted into the arc groove 111. When the first bracket 11 rotates around the third axis L3 relative to the second bracket 21, the connecting shaft 22 slides along the arc groove 111. The third axis L3 is parallel to the first axis L1.

[0079] The first bracket 11 and the second bracket 21 can achieve relative rotation around the third axis L3 via a rotation shaft 70 such as a bolt.

[0080] The arcuate groove 111 is configured to limit the rotational travel of the first bracket 11 relative to the second bracket 21 through the cooperation between the connecting shaft 22 and the arcuate groove 111. That is, the maximum rotation angle of the first bracket 11 relative to the second bracket 21 is limited by the central angle corresponding to the arcuate groove 111.

[0081] The first axis is as follows Figure 1 The axis L1 shown in FIG. Figure 1 The axis L3 shown in FIG. 1 is parallel to the axis L1.

[0082] In this way, the rotation range of the first bracket 11 relative to the second bracket 21 is limited, so that the first bracket 11 can smoothly and accurately control the rotation angle when rotating, reducing the risk of the TV colliding with the wall or other locations due to excessive rotation of the TV when adjusting the first bracket 11.

[0083] In some embodiments, see Figures 2 to 8 , the mounting frame also includes a locking structure 60. The locking structure 60 is movably connected to at least one of the second bracket 21 and the connecting shaft 22. The locking structure 60 can move to a locked state or an unlocked state. In the locked state, the locking structure 60 is used to reduce the distance between the first limiting portion 41 and the second limiting portion 31 to limit the relative rotation between the limiting structure 40 and the second transmission member 30. In the unlocked state, the second transmission member 30 and the limiting structure 40 can move relative to each other, so that the distance between the second transmission member 30 and the limiting structure 40 can be increased. And when the distance between the limiting structure 40 and the second transmission member 30 reaches the farthest distance, the first limiting portion 41 and the second limiting portion 31 can still be matched in a concave and convex manner.

[0084] In the locked state, if Figure 5 and Figure 6 As shown, the distance between the first limiting portion 41 and the second limiting portion 31 is reduced, so that the pressure at the contact point between the first limiting portion 41 and the second limiting portion 31 increases, and the friction between the limiting structure 40 and the second transmission member 30 increases with the increase of the pressure therebetween. The above-mentioned friction hinders the relative transmission between the limiting structure 40 and the second transmission member 30, making it difficult for the user to drive the second transmission member 30 to rotate relative to the limiting structure 40 when applying force to drive the first bracket 11 to rotate, thereby achieving locking.

[0085] In the unlocked state, Figure 7 and Figure 8 As shown, the first limiting portion 41 and the second limiting portion 31 can move relative to each other, so that the distance between the two increases, so that the pressure at the contact point between the first limiting portion 41 and the second limiting portion 31 decreases, and the friction force between the limiting structure 40 and the second transmission member 30 decreases as the distance between the two increases. The second transmission member 30 can rotate relative to the limiting structure 40 when an external force is applied, and the first limiting portion 41 and the second limiting portion 31 are alternately concave and convex.

[0086] In this way, after the user has completed adjusting the use angle of the first bracket 11, the user can lock the above-mentioned second transmission member 30 and the limiting structure 40 through the locking structure 60, so that the first bracket 11 can be stably fixed at the angle after the adjustment is completed, and it is not easy to rotate again, thereby improving the stability and reliability of the mounting frame.

[0087] In some embodiments, see Figures 5 to 8 The locking structure 60 includes a toggle member 61 and a push member 62. The toggle member 61 is movably connected to at least one of the second bracket 21 and the connecting shaft 22. The toggle member 61 can be moved to a locked state or an unlocked state by rotation. The push member 62 is sleeved on the connecting shaft 22 and can move on the connecting shaft 22 along the first axis L1. The push member 62 is limited along the first axis L1 between the second transmission member 30 and the toggle member 61. The toggle member 61 is used to drive the push member 62 to move along the first axis L1 in the locked state, so that the push member 62 pushes the second transmission member 30 toward the limiting structure 40.

[0088] The toggle member 61 refers to a component that can be driven by a user to move. The toggle member 61 is configured to drive the push member 62 to move along the first axis L1 toward the second transmission member 30 or to disengage from the push member 62 along the first axis L1 when moving.

[0089] The push member 62 and the connecting shaft 22 can be mutually locked about the first axis L1, that is, they cannot rotate relative to each other about the first axis L1. As an example, a non-circular through-hole can be provided in the push member 62, and the connecting shaft 22 can be configured to have a non-circular shape along a cross section perpendicular to the axial direction, so that when the connecting shaft 22 is inserted into the through-hole of the push member 62, the connecting shaft 22 and the push member 62 can be mutually locked about the first axis L1.

[0090] During use, the user activates the toggle member 61, causing it to drive the push member 62 to move along the first axis L1. The push member 62 can push the second transmission member 30 along the first axis L1, causing the second transmission member 30 to approach the limiting structure 40, thereby hindering the relative rotation between the limiting structure 40 and the second transmission member 30 and locking the second transmission member 30. The user then activates the toggle member 61 again, causing the toggle member 61 to disengage from the push member 62. When the limiting structure 40 and the second transmission member 30 rotate relative to each other, the second transmission member 30 moves along the first axis L1 toward the push member 62, pushing the push member 62 toward the toggle member 61, thereby unlocking the second transmission member 30.

[0091] In this way, the user can lock or unlock the rotation of the limiting structure 40 and the second transmission member 30 by operating the toggle member 61. The structure is simple and the operation is convenient, making the locking structure 60 more convenient to use.

[0092] In some embodiments, see Figures 5 to 8 The toggle member 61 is rotatably connected to at least one of the second bracket 21 and the connecting shaft 22 about the second axis L2. The toggle member 61 is provided with a first abutting portion 611 and a second abutting portion 612. In the locked state, the first abutting portion 611 abuts against the push member 62. In the unlocked state, the push member 62 is limited between the second abutting portion 612 and the second transmission member 30. The distance between the first abutting portion 611 and the second axis L2 is greater than the distance between the second abutting portion 612 and the second axis L2.

[0093] The toggle member 61 may be, but is not limited to, an eccentric cam member. When the first abutting portion 611 and the second abutting portion 612 rotate about the second axis L2, the first abutting portion 611 is closer to the second transmission member 30 than the second abutting portion 612, so that the first abutting portion 611 has a greater pushing stroke on the push member 62. When the user drives the toggle member 61 to rotate, the toggle member 61 can alternately correspond to the push member 62 through the first abutting portion 611 and the second abutting portion 612 during the rotation process, so that the toggle member 61 switches between driving the push member 62 and disengaging from the push member 62.

[0094] The method of pushing the push member 62 to move by rotating the toggle member 61 is more labor-saving, and the movement stroke of the push member 62 can be adjusted within a certain adjustment range when the toggle member 61 rotates, which makes it easier for users to better grasp the adjustment scale of the push member 62, simplifies the adjustment operation, and improves the flexibility of the installation bracket.

[0095] In some embodiments, the toggle member 61 has a protruding handle 613, which allows the user to better drive the toggle member 61. To adjust the movement of the push member 62, the handle 613 only needs to be rotated a certain angle, and the handle 613 occupies a relatively small operating space. This allows the mounting bracket to be used in a wider range of scenarios, allowing for proper adjustment even when the space required to mount the television is limited.

[0096] In some embodiments, see Figures 5 to 8 The push member 62 includes a first connecting portion 621 and a second connecting portion 622 connected along the first axis L1. Both the first connecting portion 621 and the second connecting portion 622 are sleeved onto the connecting shaft 22. The first connecting portion 621 passes through the second bracket 21 and the first bracket 11 along the first axis L1. The second connecting portion 622 is positioned between the second bracket 21 and the toggle member 61 along the first axis L1. The toggle member 61 is used to push against the second connecting portion 622.

[0097] During use, the user manually rotates the toggle member 61, causing it to push against the second connection portion 622, thereby causing the second connection portion 622 to move along the first axis L1. Driven by the second connection portion 622, the first connection portion 621 moves along the first axis L1 and pushes against the second transmission member 30, causing the second transmission member 30 to approach the limiting structure 40, thereby hindering relative rotation between the limiting structure 40 and the second transmission member 30, thereby locking the locking structure 60. The user then manually rotates the toggle member 61 again, causing it to disengage from the second connection portion 622. When the limiting structure 40 and the second transmission member 30 rotate relative to each other, the second transmission member 30 moves along the first axis L1 toward the first connection portion 621, pushing the first connection portion 621 toward the toggle member 61. The first connection portion 621 then drives the second connection portion 622 toward the toggle member 61, thereby unlocking the locking structure 60.

[0098] The first connecting portion 621 is provided to facilitate installation through the holes on the first bracket 11 and the second bracket 21 . Meanwhile, the second connecting portion 622 can limit the movement of the push member 62 along the first axis L1 , thereby improving the stability of the second transmission member 30 .

[0099] In some embodiments, see Figures 1 to 5The first bracket 11 includes a mounting portion 112 and a plurality of fixing portions 113. The plurality of fixing portions 113 are spaced apart on the mounting portion 112. The mounting portion 112 has a mounting surface 1121. Each fixing portion 113 extends away from the mounting surface 1121. A first transmission member 12 is provided on each fixing portion 113. A plurality of second transmission members 30 are provided, and a plurality of limiting structures 40 are also provided. The second transmission member 30, the first transmission member 12 and the limiting structure 40 are provided in a one-to-one correspondence. The connecting shaft 22 passes through the plurality of fixing portions 113, the plurality of second transmission members 30 and the plurality of limiting structures 40. The fixing portion 113 and the second transmission member 30 are configured to be rotatable around the connecting shaft 22. The connecting shaft 22 and the limiting structure 40 are in a rotationally fixed engagement. Two second transmission members 30 and two limiting structures 40 are provided between two adjacent fixing portions 113. The mounting bracket also includes a support structure 50. The support structure 50 is sleeved on the connecting shaft 22. The support structure 50 is limited between two adjacent limiting structures 40. The second transmission member 30, the limiting structure 40 and the support structure 50 are configured to be movable along the first axis L1.

[0100] It can be understood that the second transmission member 30 is limited between the fixed part 113 and the limiting structure 40 along the first axis L1, and the support structure 50 is arranged between two adjacent limiting structures 40, so that the adjacent second transmission member 30 and the limiting structure 40 are limited between the support structure 50 and the fixed part 113 along the first axis L1, and the support structure 50 can provide support for the above-mentioned two limiting structures 40 respectively along the first axis L1.

[0101] In this way, the second transmission member 30, the limiting structure 40 and the supporting structure 50 can be movably mounted on the connecting shaft 22 along the first axis L1, which facilitates the disassembly and installation of the second transmission member 30, the limiting structure 40 and the supporting structure 50 on the connecting shaft 22, and has better maintenance convenience.

[0102] In addition, the support structure 50 can move along the first axis L1, so that the distance between the limiting structure 40 and the second transmission member 30 along the first axis L1 is adjustable, and the distance between the second transmission member 30 and the first bracket 11 is also adjustable, thereby improving the adjustment flexibility of the mounting frame.

[0103] In some embodiments, see Figure 2 The first transmission member 12 is an arc-shaped rack. A plurality of teeth are disposed sequentially around the first axis L1 on the side of the first transmission member 12 facing the second transmission member 30. The second transmission member 30 is a gear. The gear and the teeth mesh with each other to achieve relative transmission.

[0104] Based on this, the transmission between the first transmission member 12 and the second transmission member 30 is more stable and reliable, and has higher transmission efficiency and longer service life.

[0105] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
