[0045] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the ceiling TV screen assembly tool provided by the embodiment of the utility model includes: a substrate 100, a first elastic clamping component 200, a second elastic clamping component 300, a first support component 400 and a second support component 500; the substrate 100 is provided with a positioning groove 101 adapted to the ceiling TV host; the first elastic clamping component 200 and the second elastic clamping component 300 are arranged opposite to each other and are respectively installed on the substrate 100, and the first elastic clamping component 200 and the second elastic clamping component 300 have a clamping tendency to approach each other; the first support component 400 and the second support component 500 are respectively installed at the bottom of the positioning groove 101, the first support component 400 has a first inclined surface 401 abutting against the first elastic clamping component 200, and the second support component 500 has a second inclined surface 501 abutting against the second elastic clamping component 300, and the first inclined surface 401 and the second inclined surface 501 are inclined from top to bottom in opposite directions.

[0046] In an optional embodiment, the first elastic clamping component 200, the second elastic clamping component 300, the first support component 400 and the second support component 500 can be respectively processed using elastic materials to form elastic devices with an integrated structure. The substrate 100 is unfolded along the xy plane and perpendicular to the z direction. The first elastic clamping component 200 and the second elastic clamping component 300 have a clamping tendency along the x direction, and the first support component 400 and the second support component 500 have an elastic supporting function along the z direction.

[0047] In the initial state, the first support component 400 and the second support component 500 protrude upward, the first inclined surface 401 pushes against the first elastic clamping component 200, and the second inclined surface 501 pushes against the second elastic clamping component 300 to expand the distance between the first elastic clamping component 200 and the second elastic clamping component 300. At this time, the screen assembly can be smoothly placed in the clamping area between the first elastic clamping component 200 and the second elastic clamping component 300.

[0048] In the clamped state, the first support assembly 400 and the second support assembly 500 are pressed down by the ceiling-mounted TV host, the first inclined surface 401 avoids the first elastic clamping assembly 200, and the second inclined surface 501 avoids the second elastic clamping assembly 300, so that the screen assembly is clamped between the first support assembly 400 and the second support assembly 500.

[0049] After the screen sub-assembly is placed in the clamping area between the first elastic clamping assembly 200 and the second elastic clamping assembly 300, the ceiling-mounted TV host is placed in the positioning groove 101, and the first support assembly 400 and the second support assembly 500 are pressed down by the gravity of the ceiling-mounted TV host. As the first support assembly 400 and the second support assembly 500 move downward, the first inclined surface 401 avoids the first elastic clamping assembly 200, and the second inclined surface 501 avoids the second elastic clamping assembly 300, and then the first elastic clamping assembly 200 and the second elastic clamping assembly 300 will approach each other, and then the screen sub-assembly will be clamped between the first support assembly 400 and the second support assembly 500, and the clamping operation will be more convenient.

[0050] like Figure 1 , Figure 2 As shown, in the embodiment of the utility model, the first elastic clamping component 200 includes: a first spring 210 and a first slider 220; the first spring 210 is installed between the first slider 220 and the substrate 100, and the first spring 210 has a tendency to drive the first slider 220 to approach the second elastic clamping component 300; the second elastic clamping component 300 includes: a second spring 310 and a second slider 320; the second spring 310 is installed between the second slider 320 and the substrate 100; the first spring 210 drives the first slider 220, and the second spring 310 drives the second slider 320, so as to generate a tendency for the first slider 220 and the second slider 320 to approach each other.

[0051] Specifically, the positioning groove 101 is located between the first slider 220 and the second slider 320. The first spring 210 and the second spring 310 both extend along the x direction. The first spring 210 drives the first slider 220 and the second spring 310 drives the second slider 320, so that the first slider 220 and the second slider 320 tend to approach each other along the x direction.

[0052] In an optional embodiment, the first elastic clamping assembly 200 also includes a first pressure plate 230 connected to the substrate 100, and the first pressure plate 230 has a first slide groove 231 adapted to the first slider 220; the second elastic clamping assembly 300 also includes a second pressure plate 330 connected to the substrate 100, and the second pressure plate 330 has a second slide groove 331 adapted to the second slider 320. The first slider 220 is limited by the first pressure plate 230, and the second slider 320 is limited by the second pressure plate 330, thereby preventing the first slider 220 and the second slider 320 from falling off relative to the substrate 100.

[0053] See also Figure 2 , Figure 4 and Figure 7 The first sliding block 220 is provided with a third inclined surface 221 which is in contact with the first inclined surface 401; see Figure 2 , Figure 5 andFigure 9 The second slider 320 is provided with a fourth inclined surface 321 that fits against the second inclined surface 501.

[0054] In the initial state, neither the first support assembly 400 nor the second support assembly 500 is pressed down. The first inclined surface 401 pushes the first slider 220 away from the second slider 320, and the second inclined surface 501 pushes the second slider 320 away from the first slider 220. At this time, the distance between the first slider 220 and the second slider 320 reaches the maximum state, facilitating the insertion of the screen sub-assembly. When the ceiling-mounted TV host is placed in the positioning groove 101 and the first support assembly 400 and the second support assembly 500 are pressed down, the first slider 220 and the second slider 320 approach each other to clamp the screen sub-assembly. The first inclined surface 401 abuts and slides against the third inclined surface 221, and the second inclined surface 501 abuts and slides against the fourth inclined surface 321. The surface contact makes the sliding smooth, more wear-resistant, and extends the service life.

[0055] As Figure 1 shown, the first elastic clamping assembly 200 and the second elastic clamping assembly 300 clamp the screen sub-assembly along the x direction; at one end of the positioning groove 101 in the y direction perpendicular to the x direction, there is a limiting end surface 102 for abutting against the ceiling-mounted TV host; at least one of the substrate 100, the first elastic clamping assembly 200, and the second elastic clamping assembly 300 is provided with a positioning and guiding portion opposite to the limiting end surface 102.

[0056] After the screen sub-assembly is inserted between the first elastic clamping assembly 200 and the second elastic clamping assembly 300, first abut one end of the ceiling-mounted TV host against the limiting end surface 102, and then release the other end of the ceiling-mounted TV host into the positioning groove 101 to make it fall along the positioning and guiding portion, thereby realizing the alignment installation of the ceiling-mounted TV host and ensuring the accurate relative position between the screen sub-assembly and the ceiling-mounted TV host.

[0057] As Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 shown, the positioning and guiding portion includes: a first guiding arc surface 201 provided on the first elastic clamping assembly 200 or a second guiding arc surface 301 provided on the second elastic clamping assembly 300. It is also possible that the positioning and guiding portion includes the first guiding arc surface 201 and the second guiding arc surface 301. The first guiding arc surface 201 and the second guiding arc surface 301 are deflected downward in the direction approaching the limiting end surface 102.

[0058] In addition, in the combinable embodiments, the positioning and guiding portion may further include a convex portion 110 provided on the substrate 100. The convex portion 110 extends into the positioning groove 101 and has a third guiding arc surface 103. The third guiding arc surface 103 is deflected downward and toward the direction approaching the limiting end surface 102.

[0059] At least one of the first guiding arc surface 201, the second guiding arc surface 301, and the third guiding arc surface 103 is provided, and the ceiling-mounted TV main unit can accurately fall into the positioning groove 101 along the arc surface.

[0060] As Figure 2 、 Figure 4 and Figure 5 shown, the first support assembly 400 includes: a first support spring 410 and a first support block 420, and the second support assembly 500 includes: a second support spring 510 and a second support block 520. The first support block 420 is provided with a first inclined surface 401, and the second support block 520 is provided with a second inclined surface 501. The bottom of the positioning groove 101 is provided with a first installation groove 104 and a second installation groove 105. The first support spring 410 and the first support block 420 are installed in the first installation groove 104, and the first support spring 410 is located below the first support block 420. The second support spring 510 and the second support block 520 are installed in the second installation groove 105, and the second support spring 510 is located below the second support block 520. In the initial state, both the first support block 420 and the second support block 520 are higher than the bottom surface of the positioning groove 101. When the ceiling-mounted TV main unit is placed in the positioning groove 101, the first support block 420 and the second support block 520 will be pressed down by the ceiling-mounted TV main unit. As the positions of the first support block 420 and the second support block 520 decrease, the first inclined surface 401 avoids the first elastic clamping assembly 200, and the second inclined surface 501 avoids the second elastic clamping assembly 300, so that the screen sub-assembly is clamped between the first support assembly 400 and the second support assembly 500.

[0061] Furthermore, the first support block 420 is connected to a first rod member 430 that slidably cooperates with the substrate 100 in the vertical direction, and the second support block 520 is connected to a second rod member 530 that slidably cooperates with the substrate 100 in the vertical direction. The x-direction, y-direction, and z-direction are perpendicular to each other in pairs. The substrate 100 extends along the xy plane. The first rod member 430 and the second rod member 530 respectively slidably pass through the substrate 100 along the z-direction, so as to ensure that the first support block 420 and the second support block 520 can smoothly move up and down relative to the substrate 100.

[0062] As Figure 1 and Figure 3As shown, a notch 106 is provided at the edge of the substrate 100. The notch 106 extends into the positioning groove 101, and the notch 106 is recessed downward relative to the bottom surface of the positioning groove 101. Through the notch 106, a finger or a tool can be inserted under the ceiling-mounted TV main unit and the screen sub-assembly, so as to take out the assembled product.

[0063] In addition, a handle 120 is installed on the substrate 100, and a plurality of support members 130 are installed at intervals at the bottom of the substrate 100. By supporting with the plurality of support members 130, it can be ensured that the substrate 100 can be placed stably on the ground or the operating table. Handles 120 can be installed on both sides of the substrate 100 respectively, and the ceiling-mounted TV screen assembly tooling can be carried by grasping the handles 120.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
