Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1, referring to Figures 1 to 7 This is the first embodiment of the present utility model. This embodiment provides a connection device for an LCD liquid crystal display module, which includes a support body 1 and a connection plate 2 disposed at the end of the support body 1.

[0030] Specifically, the sliding adjustment assembly 3, which is located inside the connecting plate 2, includes a telescopic member 31 located at the end of the connecting plate 2;

[0031] Furthermore, the main body 1 of the bracket includes a telescopic arm, a wall-mounted plate and a back plate. The wall-mounted plate is fixed to the load-bearing wall by bolts, and the connecting plate 2 is fixed to the back plate by bolts. The connecting plate 2 is connected to the reserved hole on the back of the TV display screen by bolts. The sliding adjustment component 3 is located inside the connecting plate 2, and the telescopic component 31 is located at the lower end of the TV display screen to adjust the height position of the TV display screen.

[0032] Specifically, the telescopic component 31 includes two built-in grooves 311 disposed on the connecting plate 2, each of the two built-in grooves 311 being provided with a connecting rod 312, and each of the ends of the two connecting rods 312 being provided with a concave groove 313.

[0033] Furthermore, the connecting plate 2 is fixed to the end of the bracket body 1, and two built-in grooves 311 are located at both ends of the connecting plate 2. The cross-sections of the built-in grooves 311 and the connecting rod 312 are both rectangular. The connecting rod 312 slides up and down in the built-in grooves 311. The lower end of the connecting rod 312 is provided with a concave groove 313. The lower end of the TV display screen can be placed into the concave groove 313 to support the TV display screen. The concave groove 313 and the connecting rod 312 are fixed by bolts. After the reserved hole on the back of the TV display screen is fixed to the connecting plate 2 with bolts, the bolts between the concave groove 313 and the connecting rod 312 can be removed, making it convenient for users to use the TV display screen normally.

[0034] Specifically, a right-angle slot 314 is provided on one side of each of the two connecting rods 312;

[0035] Furthermore, the right-angle slot 314 is composed of multiple consecutive slots, and the cross-section of a single slot is right-angled, with the interior consisting of inclined plates and straight plates;

[0036] Specifically, the two connecting rods 312 are symmetrical about the middle of the connecting plate 2.

[0037] Furthermore, the two connecting rods 312 are symmetrical about the middle of the connecting plate 2, keeping the lower end of the TV display screen stable when it is placed in the concave groove 313;

[0038] Specifically, the telescopic component 31 also includes a first slide groove 315 and a second slide groove 316 symmetrically opened inside the connecting plate 2. A right-angle block 317 and a spring 318 are provided in both the first slide groove 315 and the second slide groove 316.

[0039] Furthermore, both sides of the connecting plate 2 are provided with a first groove 315 and a second groove 316, and the first groove 315 and the second groove 316 on both sides are at the same height. The first groove 315 and the second groove 316 on one side are respectively connected to the built-in groove 311 on the corresponding side. The first groove 315 is located at the upper end of the second groove 316. The right-angled block 317 is a right-angled triangle, and one end of the right-angled block 317 is a rectangular plate. The cross-section of the first groove 315 and the second groove 316 is rectangular, keeping the right-angled block 317 in the first groove 315 or the second groove 316. 16. In a straight-line sliding motion, the right-angled side of the right-angled block 317 is in positive pressure contact with the straight plate of the right-angled slot 314, and the oblique side of the right-angled block 317 is in sliding pressure contact with the right-angled slot 314. Two springs 318 are connected at both ends to the inner wall of the first slide groove 315 and one end of the right-angled block 317, and the other spring 318 is connected to the inside of the second slide groove 316 and one end of the right-angled block 317. When the spring 318 is in the initial state, it is in a stationary state. At this time, the right-angled block 317 is completely located in the first slide groove 315 or the second slide groove 316 and has not entered the inner slot 311.

[0040] Specifically, two circular grooves 319 are symmetrically arranged inside the connecting plate 2. The two circular grooves 319 are connected to the first sliding groove 315 and the second sliding groove 316 respectively. A circular rod 3110 is provided in each of the two circular grooves 319.

[0041] Furthermore, the two circular grooves 319 on one side of the connecting plate 2 are respectively connected to the first slide groove 315 or the second slide groove 316, and a circular rod 3110 is slidably connected in the circular groove 319. The cross-section of the circular rod 3110 and the circular groove 319 are both circular, and the two ends of the circular rod 3110 are rounded corners and rectangular plates, respectively. The rectangular plates of the circular rod 3110 are pressed and contacted with the protrusions at both ends of the connecting rod 321, pushing the rounded corners of the circular rod 3110 to drive the right-angle block 317 to contact the right-angle slot 314. The rounded corners of the circular rod 3110 are located in the middle of the spring 318 and contact one end of the right-angle block 317. The rounded corners of the circular rod 3110 push the right-angle block 317 to slide linearly in the first slide groove 315 or the second slide groove 316.

[0042] Specifically, the sliding adjustment component 3 also includes a contact member 32, which is provided inside the connecting plate 2, and a connecting member 34 is provided at the end of the contact member 32.

[0043] Furthermore, the contact 32 is located in the middle inside the connecting plate 2, and the connecting piece 34 is located on one side of the contact 32.

[0044] Specifically, the contact element 32 includes two connecting rods 321 disposed inside the connecting plate 2, and a gear element 33 is disposed between the two connecting rods 321.

[0045] Furthermore, the two connecting rods 321 are located inside the connecting plate 2, and the middle of each connecting rod 321 is rotatably connected to the inside of the connecting plate 2. Both ends of the connecting rod 321 are protrusions, and the included angle between the protrusions at both ends of the connecting rod 321 is an obtuse angle. The protrusions at both ends of the connecting rod 321 respectively press against the rectangular plates at one end of the two round rods 3110. When one end of the connecting rod 321 contacts the rectangular plate at one end of a round rod 3110, it pushes the rectangular plate to slide within the round groove 319, and the rounded corner at the other end of the round rod 3110 pushes the right-angle block 317 towards the inner groove 311, causing the right-angle side of the right-angle block 317 to make positive contact and press against the straight plate of the right-angle slot 314, restricting the movement of the connecting rod 312 within the inner groove 311. Due to the obtuse angle between the protrusions at both ends of the connecting rod 321, the connecting rod... The protrusion at the other end of 321 does not contact the rectangular plate of another round rod 3110. At this time, the spring 318 pulls the right-angle block 317 to prevent it from engaging with a single slot of the right-angle slot 314. That is, when the connecting rod 321 rotates, one right-angle block 317 is engaged with the right-angle slot 314 and then separated, while the other right-angle block 317 is separated from the right-angle slot 314 and then engages with it. During this process, the connecting rod 312 moves downward in the inner groove 311 under the action of gravity, and then restricts the movement of the connecting rod 312 in the inner groove 311 again. This makes the connecting rod 312 descend a certain distance in the inner groove 311 every time the connecting rod 321 rotates. This is beneficial when the concave groove 313 at the lower end of the connecting rod 312 engages with the TV display screen, the weight of the connecting rod 312 increases, and the orderly descent of the connecting rod 312 is controlled.

[0046] Specifically, the gear component 33 includes a helical gear 331 and a helical gear 332 respectively disposed at the ends of the two connecting rods 321, and a helical gear 333 disposed between the helical gear 331 and the helical gear 332.

[0047] Furthermore, helical gear 1 331 and helical gear 2 332 are located on one side of the two connecting rods 321 respectively. Helical gear 1 331 and helical gear 2 332 do not contact each other, and helical gear 1 331 and helical gear 2 332 respectively drive the middle part of the corresponding connecting rod 321 to rotate inside the connecting plate 2. Helical gear 333 is simultaneously meshed between helical gear 1 331 and helical gear 2 332. Helical gear 333 is rotatably connected to the inner wall of the connecting plate 2, keeping the rotation directions of helical gear 1 331 and helical gear 2 332 different, so that the rotation directions of the two connecting rods 321 are opposite. The right-angle blocks 317 at the same height on both sides of the connecting plate 2 are simultaneously connected to the right-angle slots 314 on the corresponding side, so that the two connecting rods 312 move downward in the built-in slots 311 at the same time.

[0048] Specifically, the connecting member 34 includes an L-shaped rod 341 disposed at one end of the connecting rod 321, a slide cylinder 342 disposed on the surface of the L-shaped rod 341, a long rod 343 disposed on one side of the slide cylinder 342, a rotating plate 344 disposed inside the connecting plate 2, and a handle 345 disposed at the end of the rotating plate 344.

[0049] Furthermore, one end of the L-shaped rod 341 is connected to the middle of a connecting rod 321, and the other end extends through to the outside of the connecting plate 2. The end of the L-shaped rod 341 outside the connecting plate 2 rotates around the other end, and a sliding cylinder 342 is fitted on the surface of the end of the L-shaped rod 341 outside the connecting plate 2. The end of the L-shaped rod 341 outside the connecting plate 2 has a certain length, and the sliding cylinder 342 slides on the surface of the L-shaped rod 341. A long rod 343 is provided on one side of the sliding cylinder 342. One end of the long rod 343 is located on the rotating plate 344, and the contact point with the rotating plate 344 is located on one side of the rotating plate 344 near the side edge. The rotating plate 344 is circular. When the rotating plate 344 rotates, it drives the long rod 343 to rotate. At the same time, the sliding cylinder 342 at the other end of the long rod 343 drives the L-shaped rod 341 to rotate while sliding on the surface of the L-shaped rod 341.

[0050] Specifically, a through groove 346 is provided on the surface of the rotating plate 344, and one end of the long rod 343 is located in the through groove 346. The inner diameter of the through groove 346 is larger than the diameter of the long rod 343.

[0051] Furthermore, the inner diameter of the through groove 346 on the surface of the rotating plate 344 is larger than the diameter of the long rod 343. When the rotating plate 344 rotates, the inner wall of the through groove 346 pushes the side of the long rod 343 to rotate. At the same time, the slide cylinder 342 at one end of the long rod 343 is sleeved on the surface of the L-shaped rod 341. When the long rod 343 rotates, one end of the L-shaped rod 341 rotates around the middle of the connecting rod 321. The rotation angle of the L-shaped rod 341 is related to the radius of the rotating plate 344 of the long rod 343, so that the rotation angle of the L-shaped rod 341 in the connecting plate 2 is left and right swinging, so that the connecting rod 321 reciprocates in the connecting plate 2, controlling the two right-angle blocks 317 to contact and dock with the right-angle slot 314 in turn.

[0052] When using the TV screen, the worker can place the lower end of the TV screen into the concave groove 313 at the lower end of the two connecting rods 312. At this time, one end of the connecting rod 321 is pressed into contact with the right-angle block 317 in the slide groove 315, so that the right-angle blocks 317 in the two slide grooves 315 on both sides of the connecting plate 2 are connected to the right-angle slots 314, restricting the two connecting rods 312 in the two built-in slots 311 and maintaining the stability of the two connecting rods 312 and the TV screen. When the reserved hole on the back of the TV is not connected to the bolt hole of the connecting plate 2 and the height of the TV screen needs to be lowered, the handle 345 can be turned so that the long rod 343 and the slide cylinder 342 on the rotating plate 344 move in a circle. At the same time, the inner wall of the slide cylinder 342 slides on the surface of the L-shaped rod 341, pushing the L-shaped rod 341 around the middle of the connecting rod 321. The rod is rotated to the side until the long rod 343 and the rotating plate 344 rotate half a turn. At this time, the connecting rod 321 completes the position change, and the protrusions at both ends of the connecting rod 321 complete the alternating contact with the round rod 3110. This causes the right-angle block 317 in the first slide groove 315 to separate from the right-angle slot 314 under the action of the spring 318. The right-angle block 317 in the second slide groove 316 is pushed by the round corner of the round rod 3110 and docks with the right-angle slot 314. During this process, the gravity of the connecting rod 312 and the concave groove 313 drives the connecting rod 312 to move downward a certain distance in the inner groove 311. This allows the two connecting rods 312 to drive the TV screen to adjust its height. At the same time, the worker rotates the handle 345 a fixed number of turns to control the TV screen to descend quickly. This helps to reduce the process of multiple workers manually lifting the TV screen and speeds up the docking of the reserved hole on the back of the TV with the bolt hole of the connecting plate 2.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
