Description

Technical Field

[0001] The utility model relates to the technical field of TV cabinets, in particular to a TV cabinet with a positioning mechanism. Background Art

[0002] A TV cabinet is a cabinet used together with a television. There are three common types of TV cabinets, namely floor cabinets, combination cabinets, and integral cabinets. Floor cabinet-style TV cabinets are the most versatile of all TV cabinet styles, because the existence of floor cabinets is relatively independent and sets off the TV, so the proportion with the TV is very important. Usually the length should be two-thirds longer than the TV, so that the overall visual proportion will be good. However, the length of the current floor cabinet-style TV cabinets is fixed, which is inconvenient to adjust to adapt to and maintain a suitable proportion with different TVs. For this reason, we propose a TV cabinet with a positioning mechanism to solve the above problem. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-6 A TV cabinet with a positioning mechanism includes a fixed cabinet 1 and two expansion support platforms 2. The two expansion support platforms 2 both include top plates. Positioning mechanisms 4 are connected between the bottoms of the two top plates and the top of the fixed cabinet 1, and the positioning mechanism 4 includes a positioning piece and a locking piece 47. The positioning piece includes a limit slider 41, a support block 42 and an insert block 43 connected as a whole from top to bottom. A locking ring cover 44 is connected to the insert block 43 in a threaded manner. Two placement holes 6 for inserting the positioning piece are provided through the top of the fixed cabinet 1. Limiting grooves 3 for accommodating the limit slider 41 are provided at the bottoms of the two top plates, and the two limiting grooves 3 respectively penetrate the opposite ends of the two top plates.

[0026] Reference Figure 1-6, a TV cabinet with a positioning mechanism. The placement holes 6 include a connecting slot and a through hole. The slot is opened at the top of the fixed cabinet 1, and the through hole is opened at the inner bottom of the slot and communicates to the bottom of the fixed cabinet 1. The support block 42 is polygonal in top view, and the bottom end of the support block 42 is inserted into the matching slot. The insertion block 43 is inserted through the through hole. The limit chute 3 at the bottom of the top plate is an inverted "convex" shape. The limit slider 41 and the support block 42 are slidably matched in the limit chute 3. A retaining strip 5 is embedded at the end of the top plate and locked by screws. The retaining strip 5 covers the end of the limit chute 3.

[0027] Refer to Figure 1-6 , a TV cabinet with a positioning mechanism. The limit slider 41, the support block 42 and the insertion block 43 have accommodation holes, and a locking member 47 is provided in the accommodation holes. The accommodation holes include a through hole 45 and an embedded card hole 46. The embedded card hole 46 is opened at the bottom end of the insertion block 43. The through hole 45 is opened from the top of the limit slider 41, extends through the support block 42 and the insertion block 43 to the embedded card hole 46. The locking member 47 includes a pressing rod 472 rotatably located in the through hole 45. A hexagonal hole is opened at the bottom end of the pressing rod 472. A pressing block 471 is connected to the top of the pressing rod 472 and is located on the top of the limit slider 41. The locking member 47 further includes a threaded hole block 473 located in the embedded card hole 46. The threaded hole block 473 is threadedly sleeved on the surface of the pressing rod 472.

[0028] During assembly, insert the insertion block 43 into the through hole so that the bottom end of the support block 42 is located in the slot. Then place the threaded hole block 473 in the embedded card hole 46, and then threadedly connect the locking ring cover 44 to the surface of the insertion block 43 and cover the bottom end, which can limit the threaded hole block 473 in the embedded card hole 46. At the same time, the locking ring cover 44 presses against the bottom of the fixed cabinet 1, which can tighten the insertion block 43 in the through hole. The bottom end of the support block 42 located in the slot can prevent the insertion block 43 from rotating in the through hole when the locking ring cover 44 is turned. Then insert the pressing rod 472 into the through hole 45 from the top of the limit slider 41 until the bottom end of the pressing rod 472 is inserted into the middle position of the threaded hole block 473, and then rotate the pressing block 471 so that the pressing rod 472 is screwed into the threaded hole block 473 by thread. When the pressing block 471 is attached to the top of the limit slider 41, the staff cooperate to lift the fixed cabinet 1 and place the two ends of the fixed cabinet 1 in the relative positions of the two extended support platforms 2 respectively. The two extended support platforms 2 are in a "C" shape. At the same time, align the limit slider 41 with the end of the limit chute 3, and move the two extended support platforms 2 relatively horizontally, further making the pressing block 471 and the limit slider 41 and the position near the top of the surface of the support block 42 slide into the limit chute 3. Then connect the two retaining strips 5 to the end positions of the two top plates respectively. In this way, the two extended support platforms 2 can be used to support the fixed cabinet 1, and at the same time, moving relatively closer or farther apart can adjust the length of the entire TV cabinet, and the positioning mechanism 4 can prevent the two extended support platforms 2 from detaching from the fixed cabinet when adjusting the length of the entire TV cabinet;

[0029] When the length of the entire TV cabinet is adjusted, the staff inserts the hexagonal wrench tool into the hexagonal hole at the bottom of the extrusion rod 472, and then rotates it clockwise to make the extrusion rod 472 rotate in the screw hole block 473 through the thread and move upward, further making the top of the extrusion block 471 squeezed on the top of the limiting slide groove 3, so that the top plate is upward, the bottom of the limiting slide groove 3 is squeezed against the limiting slider 41, the extrusion block 471 and the slider 41 cannot slide in the limiting slide groove 3, and the expansion support platform 2 cannot be moved and adjusted, so as to lock and position the adjusted position distance.

[0030] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.

[0031] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
