[0068] In some embodiments of the present application, the left support member body 110, the right support member body 210 and the transverse support member body 310 can be extruded metal profiles, such as aluminum profile pipes, etc.; the left end cover 320 and the right end cover 330 of the transverse support member 300 are non-main load-bearing components, which can be plastic parts.

[0069] In some embodiments of the present application, in order to ensure that the left end cover 320, the left support member body 110, the transverse support member body 310, the right support member body 210 and the right end cover 330 can be tightly and reliably fitted when they are fitted in sequence, the left end cover 320 and the left support member body 110 are in a planar fit, the left support member body 110 and the transverse support member body 310 are in a planar fit, the transverse support member body 310 and the right support member body 210 are in a planar fit, and the right support member body 210 and the right end cover 330 are in a planar fit.

[0070] In some embodiments of the present application, the contact surface of the left end cover 320 with the left support member body 110 is a plane, and correspondingly, the outer surface of the left side plate of the left support member body 110 is a plane; the outer surface of the right side plate of the left support member body 110 is a plane, and correspondingly, the left end surface of the transverse support member body 310 is a plane; the right end surface of the transverse support member body 310 is a plane, and correspondingly, the outer surface of the left side plate of the right support member body 210 is a plane; the outer surface of the right side plate of the right support member body 210 is a plane, and correspondingly, the contact surface of the right end cover 330 with the right support member body 210 is a plane.

[0071] The top surface of the lateral support member body 310 is a plane, so as to support and connect the upright column 2 so that the upright column 2 is stably supported on the top surface of the lateral support member body 310 .

[0072] In some embodiments of the present application, the number of the lateral support member 300 is one, the left support member body 110 and the right support member body 210 are symmetrically arranged, and the distance W between the left support member body 110 and the right support member body 210 gradually decreases from front to back, such as Figure 3As shown, the left support member body 110 and the right support member body 210 are both tilted, the left end cover 320 and the right end cover 330 are tilted, and the left and right end surfaces of the lateral support member body 310 have correspondingly tilted fitting plane portions.

[0073] The connection position between the left end of the lateral support body 310 and the left support body 110 is close to the rear end of the left support body 110, approximately at one-third of the length of the left support body 110, and the connection position between the right end of the lateral support body 310 and the right support body 210 is close to the rear end of the right support body 210, approximately at one-third of the length of the right support body 210.

[0074] By adopting the above-mentioned structural form, the three components of the left support member 100, the lateral support member 300 and the right support member 200 can form a stable and firm base 1, so that the entire base 1 has a simple structure and is easy to install.

[0075] In some embodiments of the present application, the left support member 100, the lateral support member 300 and the right support member 200 are specifically connected, such as Figures 2 to 8 As shown, a first left through hole 111 for avoiding the first screw 500 to pass through is provided on the left side plate of the left support member body 110, and a first right through hole 112 for avoiding the first screw 500 to pass through is provided on the right side plate of the left support member body 110; a screw mounting hole 321 is provided on the left end cover 320, and a threaded hole 311 cooperating with the first screw 500 is provided on the left end of the transverse support member body 310. After the first screw 500 passes through the left end cover 320 and the left support member body 110 in sequence through the screw mounting hole 321, the first left through hole 111, and the first right through hole 112, it is finally screwed on the left end threaded hole 311 of the transverse support member body 310, so that the same first screw 500 can be used to realize the threaded connection of the left end cover 320, the left support member body 110, and the left end of the transverse support member body 310.

[0076] Similarly, a second right through hole 211 for avoiding the second screw 600 to pass through is provided on the right side plate of the right support member body 210, and a second left through hole for avoiding the second screw 600 to pass through is provided on the left side plate of the right support member body 210; a screw mounting hole is provided on the right end cover 330, and a threaded hole matching with the second screw 600 is provided on the right end of the transverse support member body 310. After the second screw 600 passes through the right end cover 330 and the right support member body 210 in sequence through the screw mounting hole, the second right through hole 211, and the second left through hole, it is finally screwed on the right end threaded hole of the transverse support member body 310, so that the same second screw 600 can be used to realize the threaded connection of the right end cover 330, the right support member body 210, and the right end of the transverse support member body 310.

[0077] The connection structure of the left support member 100, the lateral support member 300 and the right support member 200 is simple in structure, reliable in connection and easy to install.

[0078] In some embodiments of the present application, the screw mounting holes 321 on the left end cover 320 and the screw mounting holes 321 on the right end cover 330 are both stepped holes, so that the head of the first screw 500 is sunk into the screw mounting hole 321 on the left end cover 320, and the head of the second screw 600 is sunk into the screw mounting hole on the right end cover 330, thereby realizing a hidden setting and making the appearance of the entire base 1 simple and beautiful.

[0079] In some embodiments of the present application, Figure 5 , Figure 7 and Figure 8 As shown, an inner rib 312 is extruded on the inner wall of the transverse support body 310, a threaded hole 311 threadedly connected to the first screw 500 is formed on the left end of the transverse support body 310, and a threaded hole threadedly connected to the second screw 600 is also formed on the inner rib 312 on the right end of the transverse support body 310.

[0080] The inner rib 312 can extend from one end of the transverse support member body 310 to the other end on the inner wall of the transverse support member body 310, or can be set at only one place at each end of the inner wall of the transverse support member 300, so as to tap the thread teeth on the inner rib 312 to form a threaded hole 311 threadedly connected to the first screw 500 and a threaded hole threadedly connected to the second screw 600, respectively.

[0081] The threaded holes 311 on the transverse support body 310 are directly tapped on its inner ribs 312, which will not cause any impact on the overall stability of the extruded profile transverse support body 310. The inner ribs 312 not only enhance the strength of the extruded profile transverse support body 310, but also provide a connection and fastening function.

[0082] In some embodiments of the present application, reference Fig. 9 and Fig.10 , while combining Figure 5 and Figure 6 The left end cover 320 includes a left end cover body 322 and a first screw guide portion 323 that passes through the cylindrical shape. The screw mounting hole 321 on the left end cover 320 is formed on the left end cover body 322. The first screw guide portion 323 extends horizontally and one end is connected to the left end cover body 322 as a whole. The first screw guide portion 323 is coaxially connected to the screw mounting hole 321 on the left end cover body 322; the other end of the first screw guide portion 323 penetrates into the left support member body 110 through the first left through hole 111 and abuts against the inner wall of the left end cover body side plate outside the first right through hole 112, as shown in FIG. Figure 5 shown.

[0083] The rod length of the first screw 500 is relatively large, which is greater than the length of the first screw guide portion 323. The first screw 500 passes through the screw mounting hole 321 on the left end cover body 322 and enters the first screw guide portion 323, and its threaded connection end is exposed on the outside of the first screw guide portion 323. After the threaded connection end of the first screw 500 passes through the first right through hole 112 of the left support member body 110, it is threadedly connected with the left end threaded hole 311 of the horizontal support member body 310.

[0084] The right end cover 330 has the same structure as the left end cover 320 and is symmetrically arranged, the left support member 100 has the same structure as the right support member 200 and is symmetrically arranged, the first screw 500 has the same structure as the second screw 600 and is symmetrically arranged, that is, the entire movable display device bracket base 1 is symmetrical on the left and right, and the assembly of the second screw 600 and the right end cover 330 and the threaded connection between the second screw 600 and the right end of the horizontal support member body 310 adopt the same structural form as mentioned above, which will not be repeated here.

[0085] In some embodiments of the present application, Figure 5 and Fig.10 As shown, taking the first screw guide portion 323 on the left end cover 320 as an example, the inner hole of the first screw guide portion 323 is a tapered hole 324 with a small left end and a large right end, and the inner hole diameter of the right end is not less than the hole diameter of the first right through hole 112, so that the right end of the first screw guide portion 323 does not block the first right through hole 112, and does not hinder the threaded connection end of the first screw 500 from passing through the first right through hole 112 and then being threadedly connected to the left end of the horizontal support member body 310.

[0086] The cylindrical first screw guide portion 323 can guide and limit the installation of the first screw 500, ensuring that the first screw 500 is aligned with the first right through hole 112, and then aligned with the left end threaded hole 311 of the transverse support member body 310, so that the first screw 500 can quickly and smoothly connect the left end cover 320, the left support member body 110 and the left end of the transverse support member 300.

[0087] In order to improve the connection reliability and thereby improve the stability and structural strength of the entire display device bracket base 1, in some embodiments of the present application, there are multiple first screw guide portions 323, and correspondingly, there are multiple first screws 500, which are arranged one-to-one corresponding to the first screw guide portions 323.

[0088] By providing a plurality of first screw guides 323, the left end cover 320, the left support member body 110, and the left end of the transverse support member body 310 can be simultaneously connected by a plurality of first screws 500, thereby improving the connection stability and reliability.

[0089] Similarly, since the right end cover 330 and the left end cover 320 are structurally symmetrical, the right support member body 210 and the left support member body 110 are structurally symmetrical, and the transverse support member body 310 is symmetrical on the left and right, the right ends of the right end cover 330, the right support member body 210, and the transverse support member body 310 are also connected simultaneously by multiple second screws 600, making the connection between the three more stable and reliable.

[0090] Thus, the entire display device support base 1 is more stable and reliable.

[0091] In some embodiments of the present application, Figure 5 , Fig. 9 and Fig.10 As shown, there are two first screw guides 323 on the left end cover 320, and the two first screw guides 323 are arranged at intervals in front and back, that is, arranged at intervals along the extension direction of the left support member body 110. Accordingly, two first left through holes 111 are correspondingly arranged on the left support member body 110, two first right through holes 112 are correspondingly arranged, and two threaded holes 311 are correspondingly arranged on the left end of the transverse support member body 310. Similarly, the right end cover 330 is also connected to the right end cover 330, the right support member body 210, and the right end of the transverse support member body 310 as a whole by two second screws 600.
