[0004] In the above patent, by fixedly connecting the output end of the motor with the gearbox, the purpose of adjusting the height of the TV is achieved and it is convenient for the user to use. However, in the actual use process of the TV, it is difficult to accurately position the height during the height adjustment process of the TV, and at the same time, it is easy for the height of the TV to change due to accidental touch, thereby affecting the controllability during the use of the TV. Therefore, a TV bracket with a locking function is designed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a TV bracket with a locking function, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A TV bracket with a locking function includes a support base and a locking device. Among them, the locking device includes a rotating disk, a support column, a lifting block, a sliding plate, and a limiting rod. When adjusting the height of the TV set, first move the sliding plate in a direction away from the lifting block. The movement of the sliding plate drives the movement of the limiting rod. A first sliding groove is provided on the surface of the support base. The rotating disk is rotatably installed inside the first sliding groove. The support column is fixedly installed above the rotating disk. The lifting block is slidably installed on the surface of the support column. The sliding plate is slidably installed above the lifting block. The limiting rod is fixedly installed on the surface of the sliding plate. A limiting groove is provided on the surface of the support column. A first clockwork spring is provided between the sliding plate and the lifting block. Among them, a speed-limiting device for restricting the adjustment speed of the lifting block is provided on the surface of the lifting block. When the limiting rod moves out of the limiting groove on the surface of the support column and the locking state is released, after the locking state is released, the height of the TV set can be adjusted by moving the lifting block up and down.

[0007] According to the above technical solution, a baffle is slidably installed inside the limiting groove. The baffle is fixedly connected to the inner wall of the limiting groove through a telescopic elastic rod. When the limiting rod disengages from the limiting groove, the limit on the baffle is released. After the limit is released, the baffle pops out under the action of the telescopic elastic rod.

[0008] According to the above technical solution, the speed-limiting device includes a fixed rod, a roller, a convex strip, a connecting rod, a lifting rod, and a blocking rod. The movement of the sliding plate drives the movement of the connecting rod. The movement of the connecting rod drives the lifting rod to move downward. The downward movement of the lifting rod drives the blocking rod to move downward. A fixed groove is provided on the surface of the lifting block. The fixed rod is fixedly installed on the inner wall of the fixed groove. The roller is rotatably installed on the surface of the fixed rod. The convex strip is fixedly installed on the surface of the roller. A second sliding groove is provided on the surface of the sliding plate. The connecting rod is rotatably installed inside the second sliding groove. A third sliding groove is provided on the surface of the lifting block. The lifting rod is slidably installed on the inner wall of the third sliding groove. A fourth sliding groove is provided below the lifting rod. The blocking rod is slidably installed inside the fourth sliding groove. One end of the connecting rod away from the sliding plate is hinged to the lifting rod. When adjusting the lifting block up and down, the movement of the lifting block drives the roller to rotate. The rotation of the roller drives the convex strip to rotate. The rotation of the convex strip contacts and squeezes the blocking rod to move, realizing the restriction of the adjustment speed of the lifting block.

[0009] According to the above technical solution, a second clockwork spring is provided between the blocking rod and the fourth sliding groove. The second clockwork spring can drive the blocking rod to reset to achieve the effect of repeated extrusion. The lower part of the blocking rod is provided with a first arc surface. The rotation of the convex strip drives the blocking rod to move through contacting the first arc surface.

[0010] According to the above technical solution, it further includes a fixing device and a wire clamping device. The fixing device includes a receiving rod, a suction cup, a receiving plate, a turntable and a pressing rod. During the process of adjusting the height of the lifting block, the receiving rod is driven to rotate. The rotation of the receiving rod drives the turntable to rotate, and the rotation of the turntable drives the pressing rod to rotate. The receiving rod rotates through the upper and lower walls of the support column. The suction cup is fixedly installed inside the first chute. The receiving plate is fixedly installed above the suction cup. The turntable is fixedly installed below the receiving rod. The pressing rod is fixedly installed below the turntable. The surface of the pressing rod is formed as an inclined plane. The receiving rod slides through the upper and lower walls of the lifting block. A thread is fixedly installed on the surface of the receiving rod. The receiving rod is connected to the lifting block through the thread. A one-way valve is provided on the surface of the receiving plate. When the receiving plate moves downward, it drives the suction cup to move downward. The suction cup moves downward and discharges the air therein through the one-way valve, making the suction cup contact the tabletop more closely.

[0011] According to the above technical solution, a moving rod slidably penetrates through the surface of the rotating disk. A pressing plate is fixedly installed below the moving rod. A third clockwork spring is provided between the moving rod and the rotating disk. When the moving rod is pressed downward, the moving rod moves downward to drive the pressing plate to move downward, and the third clockwork spring can drive the moving rod to reset.

[0012] According to the above technical solution, the wire clamping device includes a support plate, a receiving column, a connecting rod, a traction wheel and a clamping column. The external wire is placed on the surface of the support plate, and then the traction wheel is rotated. After the traction wheel rotates, the clamping column is pressed downward to limit the traction wheel. The support plate is fixedly installed above the support base. The receiving column fixedly penetrates through the upper and lower walls of the support plate. The connecting rod is rotatably installed on the surface of the receiving column. The traction wheel is rotatably installed on the surface of the connecting rod. The clamping column slidably penetrates through the surface of the support plate. A clamping groove is provided at one end of the connecting rod away from the receiving column. A wire connection groove is provided on the surface of the support plate. When adjusting the high frequency of the TV, the traction wheel can effectively assist in stretching the external wire.

[0013] According to the above technical solution, the surface of the traction wheel is formed as a second arc surface. A fourth clockwork spring is provided between the connecting rod and the receiving column. The second arc surface on the surface of the traction wheel can effectively contact external wires of different sizes, improve the wire clamping effect, and maintain stability during the adjustment process.

[0014] The present invention provides a TV bracket with a locking function. It has the following beneficial effects: (1) When the height of the TV needs to be adjusted, the sliding plate is moved and the limit rod is driven to move under its action. The limit rod moves out of the limit groove on the surface of the support column and releases the locking state. Then, the height of the TV is adjusted by moving the lifting block up and down, thereby improving the safety and controllability of the TV and preventing the height of the TV from being changed due to accidental touch. At the same time, the baffle is popped out under the action of the telescopic spring rod to prevent foreign matter and dust from entering the limit groove and causing blockage, thereby affecting the adjustment of the height of the TV and reducing subsequent maintenance costs.

[0015] (2) During the adjustment process of the TV stand with a locking function, the sliding rod moves through the connecting rod and the lifting rod to drive the stop rod to move downward and enter the motion trajectory of the convex strip. At the same time, the movement of the lifting block drives the roller to contact the support column and rotate. The rotation of the roller drives the convex strip to contact the stop rod, thereby limiting the adjustment speed of the lifting block and preventing the lifting block from slipping instantly under the action of the gravity of the TV when adjusting, thereby causing the TV to collide with the desktop and be damaged, reducing subsequent maintenance costs and improving safety during the adjustment process.

[0016] (3) The TV stand with a locking function has a lifting block that moves through a thread to drive the receiving rod to rotate. The receiving rod rotates and squeezes the receiving plate and the suction cup downward through the turntable and the pressure rod, so that the suction cup is in closer contact with the desktop. This can effectively ensure the stability of the support column during the adjustment process and prevent the support column from tilting or tipping over during the adjustment process. At the same time, when in use, the moving rod is pressed and the suction cup is squeezed through the pressure plate, which improves the stability of the TV during use, prevents it from tipping over due to accidental touch, and reduces safety hazards.

[0017] (4) The TV stand with a locking function places the external wire into the wire groove on the surface of the support plate, and then rotates the traction wheel to contact the external wire and lock it into place. When adjusting the high frequency of the TV, the traction wheel can effectively assist in stretching the external wire to prevent the external wire from getting tangled and affecting the adjustment of the TV, thereby reducing subsequent maintenance costs. At the same time, the traction wheel can achieve effective contact with external wires of different sizes, improve the effect of locking the wire, and maintain stability during the adjustment process.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1-6 , an embodiment of the present invention is: a TV bracket with a locking function, including a support base 1 and further including a locking device; wherein, the locking device includes a rotating disk 2, a support column 3, a lifting block 4, a sliding plate 5 and a limiting rod 6. A chute one is opened on the surface of the support base 1, the rotating disk 2 is rotatably installed inside the chute one, the support column 3 is fixedly installed above the rotating disk 2, the lifting block 4 is slidably installed on the surface of the support column 3, the sliding plate 5 is slidably installed above the lifting block 4, the limiting rod 6 is fixedly installed on the surface of the sliding plate 5, a limiting groove is opened on the surface of the support column 3, and a first hairspring is arranged between the sliding plate 5 and the lifting block 4; wherein, a speed limiting device for restricting the adjustment speed of the lifting block 4 is arranged on the surface of the lifting block 4. After unlocking, the height of the TV can be adjusted by moving the lifting block 4 up and down, which can improve the safety and controllability of TV use and prevent the height of the TV from changing due to accidental touch.

[0022] A baffle 7 is slidably installed inside the limiting groove, and the baffle 7 is fixedly connected to the inner wall of the limiting groove through a telescopic spring rod 8, which can prevent foreign objects and dust from entering the inside of the limiting groove and causing blockage, thereby affecting the adjustment of the TV height and reducing the subsequent maintenance cost.

[0023] The speed limiting device includes a fixed rod 91, a roller 92, a rib 93, a connecting rod 94, a lifting rod 95 and a blocking rod 96. A fixed groove is formed on the surface of the lifting block 4, and the fixed rod 91 is fixedly installed on the inner wall of the fixed groove. The roller 92 is rotatably installed on the surface of the fixed rod 91, and the rib 93 is fixedly installed on the surface of the roller 92. A second sliding groove is formed on the surface of the sliding plate 5, and the connecting rod 94 is rotatably installed inside the second sliding groove. A third sliding groove is formed on the surface of the lifting block 4, and the lifting rod 95 is slidably installed on the inner wall of the third sliding groove. A fourth sliding groove is formed below the lifting rod 95, and the blocking rod 96 is slidably installed inside the fourth sliding groove. One end of the connecting rod 94 away from the sliding plate 5 is hinged to the lifting rod 95. The rib 93 rotates and contacts and presses the blocking rod 96 to move, so as to limit the adjustment speed of the lifting block 4, prevent the lifting block 4 from slipping instantaneously under the gravity of the TV set during adjustment, thereby causing the TV set to collide with the desktop and be damaged, reducing the subsequent maintenance cost, and improving the safety during the adjustment process.

[0024] A second clockwork spring is arranged between the blocking rod 96 and the fourth sliding groove. The second clockwork spring can drive the blocking rod 96 to reset to achieve the effect of repeated pressing. The lower part of the blocking rod 96 is formed as a first arc surface, and the rib 93 rotates and drives the blocking rod 96 to move through contacting the first arc surface.

[0025] When this embodiment works, the TV set is fixedly installed on the surface of the lifting block 4. When the height of the TV set needs to be adjusted, first move the sliding plate 5 in the direction away from the lifting block 4. The movement of the sliding plate 5 drives the limiting rod 6 to move. The limiting rod 6 moves out of the limiting groove on the surface of the support column 3 and releases the locked state. After the locked state is released, the height of the TV set can be adjusted by moving the lifting block 4 up and down, which can improve the safety and controllability of the TV set during use, prevent the height of the TV set from changing due to accidental touch. At the same time, when the limiting rod 6 moves out of the limiting groove, the limit on the baffle 7 is released. After the limit is released, the baffle 7 pops out under the action of the telescopic spring rod 8 and protects the limiting groove, preventing foreign objects and dust from entering the inside of the limiting groove and causing blockage, thereby affecting the height adjustment of the TV set and reducing the subsequent maintenance cost.

[0026] The sliding plate 5 moves to drive the connecting rod 94 to move. The movement of the connecting rod 94 drives the lifting rod 95 to move downward. The downward movement of the lifting rod 95 drives the blocking rod 96 to move downward. The blocking rod 96 moves downward into the movement track of the convex strip 93. At the same time, when the lifting block 4 is adjusted up and down, the movement of the lifting block 4 drives the roller 92 to contact and rotate with the support column 3. The rotation of the roller 92 drives the convex strip 93 to rotate. The rotation of the convex strip 93 contacts and squeezes the blocking rod 96 to move, realizing the limitation of the adjustment speed of the lifting block 4, preventing the lifting block 4 from slipping instantaneously under the gravity of the TV during adjustment, thereby causing the TV to collide with the tabletop and be damaged, reducing the subsequent maintenance cost, and improving the safety during the adjustment process.

[0027] Please refer to Figure 1-8 On the basis of the above embodiment, in another embodiment of the present invention, it further includes a fixing device and a wire clamping device. The fixing device includes a receiving rod 101, a suction cup 102, a receiving plate 103, a turntable 104 and a pressing rod 105. The receiving rod 101 rotatably penetrates the upper and lower walls of the support column 3. The suction cup 102 is fixedly installed inside the first chute. The receiving plate 103 is fixedly installed above the suction cup 102. The turntable 104 is fixedly installed below the receiving rod 101. The pressing rod 105 is fixedly installed below the turntable 104. The surface of the pressing rod 105 is provided with an inclined plane. The receiving rod 101 slidably penetrates the upper and lower walls of the lifting block 4. A thread is fixedly installed on the surface of the receiving rod 101. The receiving rod 101 is threadedly connected to the lifting block 4. A one-way valve is provided on the surface of the receiving plate 103. The suction cup 102 moves downward and discharges the air therein through the one-way valve, making the suction cup 102 contact the tabletop more tightly, effectively improving the stability of the support column 3 during this adjustment process, avoiding the support column 3 from tilting or toppling during adjustment, thereby damaging the TV and reducing the subsequent maintenance cost.

[0028] A moving rod 106 slidably penetrates the surface of the rotating disk 2. A pressing plate 107 is fixedly installed below the moving rod 106. A third clockwork spring is provided between the moving rod 106 and the rotating disk 2. The downward movement of the receiving plate 103 makes the suction cup 102 contact the tabletop more tightly, improving the stability during the use of the TV, avoiding accidental touch and causing toppling, and reducing potential safety hazards.

[0029] The wire clamping device includes a support plate 111, a receiving column 112, a connecting rod 113, a traction wheel 114 and a clamping column 115. The support plate 111 is fixedly installed above the support base 1. The receiving column 112 fixedly penetrates the upper and lower walls of the support plate 111. The connecting rod 113 is rotatably installed on the surface of the receiving column 112. The traction wheel 114 is rotatably installed on the surface of the connecting rod 113. The clamping column 115 slidably penetrates the surface of the support plate 111. A card slot is formed at one end of the connecting rod 113 away from the receiving column 112. A wiring slot is formed on the surface of the support plate 111. Pressing the clamping column 115 downward makes it contact the card slot and realizes the limitation of the traction wheel 114. When adjusting the high frequency of the TV set, the traction wheel 114 can effectively assist the external wiring to be stretched, avoiding the external wiring being entangled and affecting the adjustment of the TV set, and reducing the subsequent maintenance cost.

[0030] The surface of the traction wheel 114 is formed as a second arc surface. A spiral spring four is arranged between the connecting rod 113 and the receiving column 112. The second arc surface on the surface of the traction wheel 114 can effectively contact external wirings of different sizes, improve the wire clamping effect, and maintain the stability during the adjustment process.

[0031] When this embodiment works, during the process of the lifting block 4 adjusting the height, the receiving rod 101 is driven to rotate through the thread. The rotation of the receiving rod 101 drives the turntable 104 to rotate. The rotation of the turntable 104 drives the pressure rod 105 to rotate. The rotation of the pressure rod 105 contacts and squeezes the receiving plate 103 to move downward. The downward movement of the receiving plate 103 drives the suction cup 102 to move downward. The suction cup 102 moves downward and discharges the air therein through the one-way valve, making the suction cup 102 contact the desktop more tightly, effectively supporting the stability of the support column 3 during this adjustment process, avoiding the support column 3 tilting or toppling during the adjustment, thereby damaging the TV set and reducing the subsequent maintenance cost. At the same time, after the adjustment is completed, by pressing the moving rod 106 downward, the downward movement of the moving rod 106 drives the pressing plate 107 to move downward. The downward movement of the pressing plate 107 contacts and drives the receiving plate 103 to move downward. The downward movement of the receiving plate 103 makes the suction cup 102 contact the desktop more tightly, improving the stability during the use of the TV set, avoiding accidental touch and causing toppling, and reducing the safety hazard.

[0032] Put the external wiring into the wiring slot on the surface of the support plate 111. Then rotate the traction wheel 114. The rotation of the traction wheel 114 makes the card slot enter the movement track of the clamping column 115. Press the clamping column 115 downward to contact the card slot and realize the limitation of the traction wheel 114. When adjusting the high frequency of the TV set, the traction wheel 114 can effectively assist the external wiring to be stretched, avoiding the external wiring being entangled and affecting the adjustment of the TV set, and reducing the subsequent maintenance cost. At the same time, the traction wheel 114 can effectively contact external wirings of different sizes, improve the wire clamping effect, and maintain the stability during the adjustment process.
