Description

Technical Field

[0001] This invention belongs to the field of monitor bracket technology, specifically relating to a TV monitoring monitor bracket. Background Technology

[0002] A television monitoring monitor uses electronic imaging technology, signal transmission technology, and electronic display technology to display scenes that are invisible to the human eye due to distance or obstruction on a television screen. When installing a monitoring monitor, it is necessary to set up and assemble the monitor using a mounting bracket. Generally, there are two types: mobile and fixed. Fixed monitors are mounted on fixed structures such as pillars using brackets for fixed observation, while mobile monitors are moved using casters at the bottom of the brackets to be flexibly used in various scenarios.

[0003] When moving a support frame using casters, the frame is often equipped with feet to increase ground friction and thus help to fix the frame. The feet are usually set at the four corners or symmetrically, and are usually fixed by adjusting with bolts or studs. This means that when moving or fixing the frame, the feet need to be installed and removed first. Since the feet need to be installed and removed one by one, this has a certain impact on efficiency.

[0004] To address the aforementioned issues, this application proposes a television monitoring monitor bracket. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a television monitoring monitor bracket, which is convenient for fixing and adjusting.

Limiting blocks are welded to both sides of the screw, and the limiting blocks are slidably connected to a groove opened at a corresponding position on the inner wall of the connecting plate A. One end of the screw extending out of the connecting shaft A is inserted into the connecting plate B and is welded with a pressing block. The pressing block is abutted against by pressing plate B on both sides. The pressing plate B is slidably connected in the connecting plate B, and pressing plate A is welded to both sides of the pressing plate B. The pressing plate A is inserted into the horizontal plate at a corresponding position.

[0011] As a preferred embodiment of the TV monitoring display bracket of the present invention, a locking block A is welded to one side of the extrusion plate A extending from the surface of the horizontal plate, and the side of the locking block A away from the extrusion plate A is used to insert into a fixing groove opened at a corresponding position on the surface of the wheel.

[0012] As a preferred embodiment of the television monitoring display bracket of the present invention, it further includes an adjustment component installed between the bracket body and the mounting plate;

[0013] The adjustment assembly includes a mounting base fixedly disposed on one side of the mounting plate surface and a sleeve A fixedly disposed on one side of the mounting base surface. A collar is slidably fitted on the surface of the sleeve A, and the collar is fixedly disposed in a through groove opened at a corresponding position on the surface of the bracket body. A crossbeam is rotatably connected to both sides of the surface of the sleeve A at positions corresponding to the inner wall of the collar, and the side of the crossbeam away from the sleeve A is slidably connected to an annular guide groove opened in the inner wall of the collar. A semi-arc-shaped arc plate is slidably fitted on one side of the sleeve A extending out of the collar, and the arc plate is rotatably connected to the surface of the collar.

[0014] As a preferred embodiment of the TV monitoring display bracket of the present invention, a pulley is rotatably connected to one side of the crossbar inserted into the guide groove of the inner wall of the collar, and the surface of the pulley abuts against the inner wall of the guide groove.

[0015] As a preferred embodiment of the TV monitoring display bracket of the present invention, the sleeve A is divided into two sections along its axial direction, including a first section A located at the top and a second section A located at the bottom. A sliding rod is fixedly connected between the two sections. A sliding sleeve is slidably fitted on the surface of the sliding rod. The sliding sleeve is slidably connected in an arc-shaped movable groove opened at a corresponding position on the inner wall of the arc-shaped plate. A positioning screw is screwed to the lower end face of the second section A, and a locking rod is abutted and connected to the surface of the positioning screw and on both sides of the screw. The locking rod is inserted into the lower end face of the sleeve A, and the side of the locking rod inserted into the sleeve A abuts against the surface of the sliding sleeve.

[0016] As a preferred embodiment of the TV monitoring display bracket of the present invention, a connecting shaft B is rotatably connected to the surface of the sleeve A. A knob C is welded to one end of the connecting shaft B, and a gear A is welded to the end of the connecting shaft B that is inserted into the sleeve A. Gear B is meshed with the surface of gear A. A stud is fixedly installed in the through hole at the center of gear B. One end of the stud is rotatably connected to the inner wall of the sleeve A, and the sleeve B is screwed onto the surface of the stud and located on one side of gear B. Oppositely distributed locking blocks B are welded to the surface of the sleeve B, and the locking blocks B are slidably connected in a longitudinal groove opened in the inner wall of the sleeve A. The side of the sleeve B extending out of the surface of the sleeve A is fixedly connected to the mounting base by an external bolt.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] By setting up a fixed component, stepping on the pedal moves the connecting plate B via connecting plate A, which in turn moves the horizontal plate. This allows the horizontal plate to simultaneously contact the surface of the wheels, thereby increasing friction and assisting in the product's positioning and fixation. Furthermore, external fasteners further secure the pedal. Compared to traditional bracket installation and removal methods, this approach ensures fixation while requiring only stepping on the pedal, making it convenient for users and ensuring that work efficiency is not affected.

[0019] By setting up an adjustment component, the sleeve A is pushed to rotate the mounting plate through the crossbeam to a suitable angle, and the sleeve A is pushed to rotate the crossbeam along the collar, so that people can adjust the placement angle of the monitor according to their own needs.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figure 1-9 As shown;

[0036] The TV monitor bracket includes a base 1, casters 2 installed at the four corners of the bottom of the base 1, and a bracket body 3 installed on the base 1. A mounting plate 5 is installed on the side of the bracket body 3 away from the base 1.

[0037] In this implementation plan: the monitor is mounted on the mounting plate 5 and moved as a whole by the casters 2, thereby assisting people in moving the monitor. The bracket is usually equipped with feet to increase ground friction, thereby assisting in fixing the bracket. The feet are generally set at the four corners or symmetrically, and are usually fixed by adjusting with bolts or studs. This means that when moving or fixing the bracket, the feet need to be installed and removed first. The feet need to be installed and removed one by one, which has a certain impact on efficiency.

[0038] The TV monitor stand also includes a fixing component 4 installed in a slot at the center of the base 1;

[0039] The fixing component 4 includes a connecting plate A43 inserted into the slot of the base 1, a hollow pedal 41 welded to the top of the connecting plate A43, and a connecting plate B44 welded to the bottom of the connecting plate A43. A horizontal plate 45 is welded to both ends of the connecting plate B44 and between the wheels 2. The two ends of the horizontal plate 45 are respectively used to abut against the surface of the wheels 2 at the corresponding positions.

[0040] In this implementation plan: by stepping on the pedal 41, the connecting plate B44 is moved through the connecting plate A43, and the connecting plate B44 moves the horizontal plate 45, so that the horizontal plate 45 can simultaneously come into contact with the surface of the wheel 2. The pedal 41 is installed and fixed by external fasteners, thereby increasing friction to help people limit and fix the product. Compared with the traditional bracket installation and removal, this method ensures fixation, and the fixing method only requires people to step on it, thus making it convenient for people to use and ensuring that work efficiency is not affected.

[0041] In an optional embodiment, a groove is provided at the center of the upper surface of the pedal 41, and a connecting shaft A421 is rotatably connected in the groove. A knob A42 is welded to one end of the connecting shaft A421 located in the groove, and a torsion spring seat 422 is rotatably sleeved on the other end of the connecting shaft A421 inserted into the hollow structure of the pedal 41. The torsion spring seat 422 is fixedly connected to the inner wall of the hollow structure of the pedal 41. A turntable 423 is fixedly sleeved on the side of the connecting shaft A421 opposite to the torsion spring seat 422. A pin is welded to the surface of the turntable 423 and located on the side of the connecting shaft A421, and a connecting rod 424 is rotatably sleeved on the surface of the pin. A protrusion 425 is rotatably connected to the side of the connecting rod 424 away from the pin. The protrusion 425 is inserted into a slot opened on the surface of the pedal 41, and the side of the protrusion 425 away from the connecting rod 424 extends out of the surface of the pedal 41.

[0042] In this embodiment: In conjunction with the above, when the pedal 41 is inserted into the slot on the surface of the base 1, the turntable 423 rotates under force, and the connecting rod 424 can push the protrusion 425 to move, so that the protrusion 425 abuts against the inner wall of the slot of the base 1, thereby increasing the friction and thus assisting in fixing the horizontal plate 45.

[0043] In an optional embodiment, the inner walls of the base 1 slot are sloped inward on both sides, and the inner walls of the base 1 slot are provided with a fixing groove that matches the protrusion 425 below the slope.

[0044] It should be noted that this design allows the torsion spring inside the torsion spring seat 422 to push the connecting shaft A421 to rotate on its own elasticity when it is not under force, so that the turntable 423 is rotated under force, causing the protrusion 425 to abut against the inner wall of the slot of the base 1.

[0045] It should be noted that after the torsion spring seat 422 is set, the torsion spring seat 422 can drive the turntable 423 to rotate under force through its own elasticity, thereby assisting the protrusion 425 to move and complete the fixation of the pedal 41. At the same time, when it is necessary to separate the pedal 41 from the base 1, it is necessary to control the turntable 423 to reverse so as to separate the protrusion 425 from the base 1.

[0046] In this embodiment: This design allows the protrusion 425 to be inserted into the fixing groove of the base 1, thereby fixing the horizontal plate 45. At the same time, the horizontal plate 45 is affected by the downward movement and comes into contact with the surface of the wheel 2, increasing the friction between the wheel 2 and the wheel 2, making the wheel 2 less likely to rotate under force, and assisting people in limiting the wheel 2.

[0047] In an optional embodiment, a through hole is provided in the knob A42, and a knob B4214 is inserted into the through hole. The knob B4214 passes through the knob A42 and is rotatably connected to the connecting plate A43. A screw 4211 is screwed into one end of the knob B4214 located in the connecting plate A43. Limiting blocks 4213 are welded to both sides of the screw 4211, and the limiting blocks 4213 are slidably connected to the groove opened at the corresponding position on the inner wall of the connecting plate A43. One end of the screw 4211 extending out of the connecting shaft A421 is inserted into the connecting plate B44 and a pressing block 4212 is welded thereto. A pressing plate B453 is abutted to both sides of the pressing block 4212. The pressing plate B453 is slidably connected in the connecting plate B44, and a pressing plate A451 is welded to both sides of the pressing plate B453. The pressing plate A451 is inserted into the horizontal plate 45 at the corresponding position.

[0048] In this embodiment: by rotating the knob B4214, the screw 4211 is forced to push the extrusion block 4212 to extrude the extrusion plate B453, so that the extrusion plate B453 pushes the extrusion plate A451 to contact the wheel 2, further increasing the friction with the wheel 2, preventing the wheel 2 from rotating, and ensuring the fixing effect.

[0049] In an optional embodiment, a locking block A452 is welded to one side of the extrusion plate A451 extending from the surface of the transverse plate 45, and the side of the locking block A452 away from the extrusion plate A451 is used to insert into a fixing groove opened at a corresponding position on the surface of the wheel 2.

[0050] In this embodiment: In conjunction with the above, while the extrusion plate A451 moves, it can push the locking block A452 into the fixing groove of the wheel 2, further fixing the wheel 2. At this time, due to the limiting effect of the locking block A452, the wheel 2 cannot rotate, making the placement effect of this product more stable.

[0051] In conjunction with the aforementioned patents, the system also includes an adjustment assembly 6 installed between the bracket body 3 and the mounting plate 5;

[0052] The adjustment assembly 6 includes a mounting base 62 fixedly disposed on one side of the surface of the mounting plate 5 and a sleeve A61 fixedly disposed on one side of the surface of the mounting base 62. A collar 64 is slidably fitted on the surface of the sleeve A61, and the collar 64 is fixedly disposed in a through groove opened at a corresponding position on the surface of the bracket body 3. A crossbeam 65 is rotatably connected to both sides of the surface of the sleeve A61 at positions corresponding to the inner wall of the collar 64. The side of the crossbeam 65 away from the sleeve A61 is slidably connected to an annular guide groove opened in the inner wall of the collar 64. A semi-arc-shaped arc plate 66 is slidably fitted on one side of the sleeve A61 extending out of the collar 64, and the arc plate 66 is rotatably connected to the surface of the collar 64.

[0053] In this implementation plan: the sleeve A61 is pushed to rotate the mounting plate 5 to a suitable angle via the crossbeam 65, and the sleeve A61 is pushed to rotate the crossbeam 65 along the collar 64, so that people can adjust the placement angle of the monitor according to their own needs.

[0054] It should be noted that the crossbar 65 can rotate along the inner wall of the collar 64, thereby driving the mounting plate 5 to adjust its angle through the sleeve A61, so as to achieve placement at different angles.

[0055] In an optional embodiment, a pulley 651 is rotatably connected to one side of the guide groove inside the inner wall of the collar 64, and the surface of the pulley 651 abuts against the inner wall of the guide groove.

[0056] In this embodiment: This design is used to reduce friction during movement via pulley 651.

[0057] In an optional embodiment, the sleeve A61 is divided into two sections along its axial direction, including a first section A located at the top and a second section A located at the bottom. A sliding rod 612 is fixedly connected between the two sections. A sliding sleeve 611 is slidably fitted on the surface of the sliding rod 612. The sliding sleeve 611 is slidably connected in an arc-shaped movable groove opened at a corresponding position on the inner wall of the arc-shaped plate 66. A positioning screw 67 is screwed to the lower end face of the second section A, and a locking rod 671 is abutted and connected to the surface of the positioning screw 67 and on both sides of the screw. The locking rod 671 is inserted into the lower end face of the sleeve A61, and the side of the locking rod 671 inserted into the sleeve A61 abuts against the surface of the sliding sleeve 611.

[0058] In this embodiment: In conjunction with the above, after adjusting the position of the sleeve A61, the positioning screw 67 is moved by rotating the positioning screw 67, while pushing the locking rod 671 to contact the sliding sleeve 611, thereby completing the fixing of the sleeve A61 and thus completing the adjustment of the display.

[0059] It should be noted that when sleeve A61 is flipped, the arc plate 66 can use the sliding sleeve 611 to assist in limiting sleeve A61 and ensure smooth movement.

[0060] In an optional embodiment, a connecting shaft B631 is rotatably connected to the surface of sleeve A61. A knob C63 is welded to one end of the connecting shaft B631, and a gear A632 is welded to the end of the connecting shaft B631 that is inserted into sleeve A61. A gear B633 is meshed with the surface of gear A632. A stud 636 is fixedly installed in the through hole at the center of gear B633. One end of the stud 636 is rotatably connected to the inner wall of sleeve A61. Sleeve B635 is screwed onto the surface of stud 636 and located on one side of gear B633. Oppositely distributed locking blocks B634 are welded to the surface of sleeve B635, and the locking blocks B634 are slidably connected in a longitudinal groove opened in the inner wall of sleeve A61. One side of sleeve B635 extending out of the surface of sleeve A61 is fixedly connected to mounting base 62 by external bolts.

[0061] In this embodiment: by rotating the knob C63 to drive the gear A632 to rotate, the gear B633 drives the stud 636 to rotate, and at the same time, the sleeve B635 can be pushed by force to move the mounting plate 5, thereby adapting and adjusting the placement height of the display.

[0062] Working principle and usage process of this invention:

[0063] When the pedal 41 is pressed, the connecting plate A43, connecting plate B44, and horizontal plate 45 move downward as a whole, and the pedal 41 enters the slot of the base 1. The slot wall causes the protrusion 425 to retract, and the protrusion 425 drives the connecting rod 424 to move. The connecting rod 424 drives the turntable 423, connecting shaft A421, and knob A42 to rotate synchronously. When the connecting shaft A421 rotates, it will give a force to the torsion spring in the torsion spring seat 422. When this force disappears, the torsion spring will generate a rebound force. When fully pressed, the protrusion 425 matches the slope structure in the slot. At this time, the protrusion 425 has room to move, and the rebound force of the torsion spring begins to take effect, driving the connecting shaft A421 to rotate in the opposite direction, thereby causing the protrusion 425 to extend outward, and the pedal 41 is fixed.

[0064] Rotating knob B4214 causes screw 4211 to move down, pressing block 4212 to move down, pressing block 4212 pushes pressing plate B453 to both sides, pressing plate B453 pushes pressing plate A451 to both sides, so that pressing plate A451 fits against wheel 2, and wheel 2 is fixed; in addition, the locking block A452 on pressing plate A451 can be inserted into the corresponding fixing groove on wheel 2 for further fixation.

[0065] When the fixation is released, rotate knob B4214 in the opposite direction to move the extrusion block 4212 upward and the extrusion plate A451 away from the wheel 2, thus releasing the fixation of the wheel 2.

[0066] Rotate knob A42, which drives turntable 423 and connecting shaft A421 to rotate synchronously, causing protrusion 425 to retract, allowing pedal 41 to have space to come out of slot in base 1. At this time, connecting shaft A421 will exert a force on torsion spring. After releasing, the rebound force of torsion spring will take effect, causing block A425 to extend out again, preventing pedal 41 from entering slot in base 1.

[0067] When the adjustment component is used to adjust the left and right tilt angle of the display, the arc plate 66 can be rotated. The arc plate 66 drives the sliding sleeve 611 to rotate, the sliding sleeve 611 drives the sleeve A61 to rotate, and the sleeve A61 drives the cross frame 65 to rotate synchronously. The synchronous rotation of the sleeve A61 and the cross frame 65 ensures that the cross frame 65 can always be used as a pivot when adjusting the tilt angle later.

[0068] To adjust the pitch angle, manually rotate the positioning screw 67 along the movable groove of the arc plate 66. Once rotated to the appropriate angle, tighten the positioning screw 67, causing the locking rod 671 to press upward against the sliding sleeve 611. The sliding sleeve 611 then fits tightly against the inner wall of the movable groove, thus achieving fixation.

[0069] In addition, by rotating the knob C63, the gear A632 is rotated, which in turn causes the gear B633 to rotate the stud 636. At the same time, the sleeve B635 can be pushed by force to move the mounting plate 5, thereby adapting and adjusting the placement height of the monitor.

[0070] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
