DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] An embodiment of the present invention provides a floor tile screen, such as Figure 1 and Figure 2 As shown, it includes a display screen module 5 and a floor tile screen box, and the display screen module 5 is installed on the top surface of the box frame 1.

[0023] like Figures 3 to 6 As shown, the floor tile screen box includes a box frame 1 and an adjusting member 2. The box frame 1 is provided with an adjusting portion 14. The adjusting portion 14 is provided with an adjusting hole 11 that passes through the adjusting portion 14 along the height direction of the box frame 1. The adjusting member 2 is provided in the adjusting hole 11.

[0024] The adjusting hole 11 includes an internal threaded hole 112, and the adjusting member 2 includes an adjusting screw 21 and a support rod 22. The adjusting screw 21 is threadedly connected to the internal threaded hole 112, and the bottom end of the adjusting screw 21 and the top end of the support rod 22 are rotatably connected around the axis of the adjusting screw 21. The relative displacement of the adjusting screw 21 and the support rod 22 in the axial direction of the adjusting screw 21 is limited, and the bottom end of the support rod 22 can extend out of the box frame 1 through the bottom end opening of the adjusting hole 11 to abut the ground.

[0025] An operating portion is provided at the top of the adjusting screw 21 . The operating portion is exposed from the box frame 1 through the top opening of the adjusting hole 11 . By rotating the operating portion, the adjusting screw 21 can be rotated relative to the adjusting portion 14 .

[0026] Specifically, Figure 3 and Figure 4 The adjusting part 2 of the floor tile screen is in the initial state, and the adjusting screw 21 and the supporting rod 22 of the adjusting part 2 are adjusted to the adjusting hole 11 of the box frame 1. At this time, the adjusting part 2 does not occupy additional space outside the box frame 1, and the space occupied by the floor tile screen box is small, which is convenient for transporting the floor tile screen box.

[0027] Before the floor tile screen box is installed on the ground, since the adjusting screw 21 is threadedly connected to the internal threaded hole 112 of the adjusting portion 14, the adjusting screw 21 and the support rod 22 are rotatably connected around the axis of the adjusting screw 21, and the relative displacement of the adjusting screw 21 and the support rod 22 along the axial direction of the adjusting screw 21 is limited. Therefore, when the staff rotates the adjusting screw 21 through the operating portion, the adjusting screw 21 threadedly matched with the internal threaded hole 112 of the adjusting portion 14 can rotate downward, and the adjusting screw 21 drives the support rod 22 to extend downward from the box frame 1, as shown in FIG. Figure 5 The state shown by the adjusting member 2 of the floor tile screen is shown.

[0028] Floor tile screen box Figure 5 In the usage state shown, the floor tile screen is installed on the ground, with the bottom end of the support rod 22 abutting the ground to support the display screen module 5, so that the floor tile screen is laid on the ground and can withstand walking and stepping.

[0029] When the floor tile screen needs to be leveled upwards, the staff rotates the operating part, and the adjusting screw 21 threadedly engaged with the internal threaded hole 112 of the adjusting part 14 rotates relative to the adjusting part 14, and the adjusting screw 21 has a tendency to move downward. Since the bottom end of the support rod 22 always abuts the ground, the relative displacement of the adjusting screw 21 and the support rod 22 in the axial direction of the adjusting screw 21 is limited. Therefore, the adjusting screw 21 cannot move along its axial direction, and the force of the adjusting screw 21 on the adjusting part 14 causes the adjusting part 14 to move upward, thereby adjusting the horizontality of the top surface of the floor tile screen box.

[0030] When the floor tile screen needs to be leveled downward, the staff rotates the operating part in the opposite direction, and the adjusting screw 21 threadedly engaged with the internal threaded hole 112 of the adjusting part 14 rotates relative to the adjusting part 14, and the adjusting screw 21 moves upward along its axial direction. Since the relative displacement of the adjusting screw 21 and the support rod 22 in the axial direction of the adjusting screw 21 is restricted, the adjusting screw 21 drives the support rod 22 to move upward to reduce the length of the support rod 22 extending from the bottom end opening of the adjusting hole 11, thereby lowering the height of the corresponding adjusting part 14 from the ground, thereby adjusting the horizontality of the floor tile screen.

[0031] During the entire leveling process, since the bottom end of the adjusting screw 21 is rotatably connected to the top end of the support rod 22, when the adjusting screw 21 is rotated through the operating part, there is no relative rotational movement between the bottom end of the support rod 22 and the ground, thereby avoiding the problem of adjustment resistance caused by the rotational friction between the adjusting member 2 and the ground, reducing the resistance to rotating the adjusting screw 21, and facilitating the leveling of the floor tile screen.

[0032] In one embodiment, if Figure 7 As shown, a plurality of adjusting parts 14 are provided, a plurality of adjusting members 2 are provided, and each adjusting member 2 is provided in the adjusting hole 11 of the corresponding adjusting part 14 .

[0033] By selectively rotating the operating portion of the adjusting screw 21 of one or more adjusting members 2 , the adjusting screw 21 of one or more adjusting members 2 can be rotated relative to the corresponding adjusting portion 14 , thereby adjusting the horizontality of the top surface of the box frame 1 .

[0034] The multiple adjustment members 2 can adjust multiple positions of the box frame 1 respectively, so that the top surface of the box frame 1 can be finely adjusted, which is beneficial to improving the accuracy of leveling.

[0035] In one embodiment, if Figure 9 and Figure 10 As shown, the box frame 1 is square, and adjustment parts 14 are provided at the four corners of the box frame 1.

[0036] In one embodiment, two levels 6 are provided on opposite sides of the top surface of the box body, and the two levels 6 on each side are respectively provided close to the two adjusting portions 14 on the corresponding side.

[0037] In one embodiment, if Figures 3 to 6 As shown, it also includes a connecting screw 3. The bottom end of the adjusting screw 21 is provided with a connecting hole 211 and a locking threaded hole 212. The connecting hole 211 extends along the axial direction of the adjusting screw 21, and the locking threaded hole 212 extends along the radial direction of the adjusting screw 21 and is connected to the connecting hole 211.

[0038] The top end of the support rod 22 is inserted into the connecting hole 211, and an annular groove 221 extending along its circumference is provided on the outer wall of the support rod 22. One end of the connecting screw 3 is threadedly connected to the locking threaded hole 212, and the other end of the connecting screw 3 is inserted into the annular groove 221 so that the bottom end of the adjusting screw 21 is rotatably connected to the top end of the support rod 22.

[0039] The adjusting screw 21 and the support rod 22 are rotatably connected by the connecting screw 3, which has a simple structure and is easy to process and install. In addition, the adjusting screw 21 can radially limit the support rod 22 inserted into the connecting hole 211, so that the support rod 22 can only move along the axial direction of the adjusting screw 21, thereby preventing the support rod 22 from tilting axially and improving the stability of the support rod 22 when it contacts the ground.

[0040] In other embodiments, Figure 7 and Figure 8 As shown, the bottom end of the adjusting screw 21 and the top end of the support rod 22 can be connected through a bearing. Specifically, the inner ring of the bearing is fixed to the top end of the support rod 22, and the outer ring of the bearing is fixed to the bottom end of the adjusting screw 21.

[0041] In one embodiment, a limited rotation structure is provided between the support rod 22 and the box frame 1 , which limits the rotation of the support rod 22 to prevent the support rod 22 from rotating under the friction between the support rod 22 and the adjusting screw 21 .

[0042] In one embodiment, the rotation-limiting structure includes a baffle 12. A limiting plane 222 is provided on the outer wall of the support rod 22. The limiting plane 222 extends along the length of the support rod 22. The baffle 12 is fixed to the box frame 1 and has a stop surface that is flush with the limiting plane 222. The baffle 12 limits the rotation of the support rod 22. The stop surface and the limiting plane 222 are in surface contact, resulting in a large contact area and high limit reliability.

[0043] Specifically, a mounting groove is provided on the bottom surface of the box frame 1 , which is arranged opposite to the limiting plane 222 . The mounting groove has an opening facing away from the adjusting screw 21 and communicates with the adjusting hole 11 , and the baffle 12 is installed in the mounting groove.

[0044] In other embodiments, the limiting structure may include a limiting pin, and a limiting long groove extending along the length direction of the support rod 22 is provided on the outer wall thereof, one end of the limiting pin is fixed to the box frame 1, and the other end is inserted into the limiting long groove.

[0045] In one embodiment, the adjusting screw 21 includes a threaded rod 214 and an adjusting head 213, the cross-sectional area of ​​the adjusting head 213 is larger than the cross-sectional area of ​​the threaded rod 214, the top end of the threaded rod 214 is connected to the adjusting head 213, the threaded rod 214 is threadedly connected to the internal threaded hole 112, and the bottom end of the threaded rod 214 is rotatably connected to the support rod 22.

[0046] The adjustment hole 11 also includes a mounting hole 111, and the adjustment head 213 is installed in the mounting hole 111. A limiting table 15 is formed between the bottom end of the mounting hole 111 and the top end of the internal threaded hole 112. The limiting table 15 can abut against the bottom surface of the adjustment head 213 to remind the staff that the adjustment screw 21 has been rotated to the lowest position, which is conducive to adjusting all adjustment parts 2 connected to the box frame 1 to the same height.

[0047] Moreover, the cross-sectional area of ​​the regulating head 213 is relatively large and the structural strength is high, which facilitates the design of the operating portion on the regulating head 213 having a larger cross-sectional area.

[0048] In one embodiment, if Figure 9 and Figure 10 As shown, the adjusting head 213 is cylindrical, and the side wall of the adjusting head 213 is provided with a plurality of adjusting teeth 215 distributed along the circumferential direction. The side of the box frame 1 is provided with an adjusting window 13 connected to the mounting hole 111, and the adjusting tooth 215 is exposed from the box frame 1 through the adjusting window 13 so that the adjusting tooth 215 can be moved through the adjusting window 13.

[0049] When leveling the floor tile screen, the staff can rotate the adjusting screw 21 through the adjusting tooth 215 on the side of the box frame 1 without interfering with the display screen module 5 on the top surface of the box frame 1. Therefore, there is no need to remove the display screen module 5. Compared with rotating the adjusting screw 21 from the top of the box frame 1, it is necessary to remove the display screen module 5, which saves disassembly steps and improves leveling efficiency.

[0050] In one embodiment, if Figure 7 and Figure 8 As shown, both side walls of the box frame 1 adjacent to the adjustment portion 14 are provided with adjustment windows 13 , so that the operator can selectively adjust the adjustment teeth 215 on the screw of the corresponding adjustment hole 11 through any adjustment window 13 .

[0051] In one embodiment, a stopper 4 is further included. The stopper 4 is fixed to the box frame 1 and located above the adjustment hole 11. The stopper 4 is used to limit the adjustment member 2 from extending from the top of the adjustment hole 11. Because the display screen module 5 blocks the adjustment hole 11 when the adjustment screw 21 is rotated via the adjustment teeth 215, and the position of the adjustment screw 21 within the adjustment hole 11 cannot be seen, the adjustment head 213 is prone to extending from the top opening of the adjustment hole 11 and damaging the display screen module 5. Therefore, the stopper 4 is provided to limit the adjustment screw 21 from extending from the top opening of the adjustment hole 11, thereby avoiding damage to the display screen module 5 and improving the safety of the floor tile screen during leveling.

[0052] In one embodiment, if Figure 10As shown, the limiting member 4 is a disc head screw with a washer, which is screwed into the adjusting part 14 from the top surface of the adjusting part 14, and the washer of the disc head screw blocks the top opening of the adjusting hole 11.

[0053] Specifically, two disc head screws with washers are arranged in the radial direction of the adjusting hole 11.

[0054] In an embodiment, as shown in Figure 9 and Figure 10 As shown, the operation part is provided with an operation hole 216 and a plurality of grooves 217, which are located at the top end surface of the adjusting head 213, the operation hole 216 extends in the axial direction of the adjusting head 213, and the operation hole 216 is used for inserting a tool to rotate the adjusting screw 21.

[0055] Specifically, before adjusting, the display screen module 5 needs to be removed first, and then the operator inserts a tool into the operation hole 216 to rotate the adjusting screw 21. The top space of the box frame 1 is large, which is convenient for the operator to use the tool to quickly level.

[0056] The plurality of grooves 217 are arranged around the outside of the operation hole 216, the grooves 217 have openings facing away from the threaded rod 214, and the grooves 217 are used for the operator to rotate the adjusting screw 21 by fingers.

[0057] Since the adjusting screw 21 in the present application will not be subjected to the resistance of the ground when rotating, the resistance of the adjusting screw 21 when rotating is small, which is convenient for adjusting. Therefore, a plurality of grooves 217 are arranged on the top surface of the adjusting screw 21, and the operator can insert fingers into the grooves 217 to rotate the adjusting screw 21, so as to manually adjust without adjusting tools.

[0058] In an embodiment, the grooves 217 are provided with four, and the operation hole 216 is arranged at the center position of the top surface of the adjusting head 213, and the four grooves 217 are arranged around the outside of the operation hole 216.

[0059] In an embodiment, the bottom of the supporting rod 22 is provided with a mounting threaded hole 223 extending in the length direction thereof, which can be used as a connecting threaded hole when the floor tile screen is placed vertically, at this time, the bottom surface of the supporting rod 22 does not protrude from the bottom surface of the box frame 1.

[0060] In addition, an embodiment of the present application provides a floor tile screen box, which has the same structure as the floor tile screen box in any of the above embodiments, and details are not repeated here.

[0061] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention, and should all be included in the scope of protection of the present invention.
