[0037] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] See also Figures 1 to 8 The support base 100 of the display bracket 1000 of the utility model includes a support body 110, a mounting base 120, a connecting shaft 130 and a roller 140; wherein the support body 110 includes a top plate 111 and a bottom plate 112 arranged opposite to each other in the up-down direction and a side plate 113 connecting the top plate 111 and the bottom plate 112, and the support body 110 is provided with a storage cavity located between the top plate 111 and the bottom plate 112; the material strength of the mounting base 120 is higher than that of the support body 110, and the mounting base 120 is C The mounting seat 120 is provided in a font and fixed to one side of the side plate 113, and has an upper mounting surface (not marked) that is in contact with the upper surface of the top plate 111 and a lower mounting surface (not marked) that is in contact with the lower surface of the bottom plate 112; the mounting seat 120 is provided with an assembly hole (not marked) extending in the up-down direction, and the assembly hole is used to cooperate with the fixing rod 200 of the display bracket 1000; the connecting shaft 130 is provided on the lower side of the mounting seat 120, and the roller 140 is connected to the connecting shaft 130, and the roller 140 partially extends from the lower surface of the bottom plate 112.

[0040] There are many materials for making the support body 110. The support body 110 can be made of plastic, metal and other materials, which are not listed here one by one. There are many shapes of the support body 110. The support body 110 can be a cube, a truncated cone and other shapes, which are not listed here one by one. The cross section of the support body 110 in the vertical direction of the utility model is set in a trapezoidal shape, that is, the support body 110 has a top plate 111 and a bottom plate 112 arranged relatively in the vertical direction and a side plate 113 connecting the top plate 111 and the bottom plate 112. A storage cavity is formed between the top plate 111 and the bottom plate 112. An injection port is provided on the top plate 111. The injection port can be used to inject fillers such as liquid and fine sand to increase the overall weight of the storage cavity. When it is necessary to carry it, it is only necessary to discharge the filler in the storage cavity. When it is necessary to stand the support body 110 on the ground or a support surface, it is only necessary to inject the filler into the storage cavity.

[0041] The C-shaped arrangement of the mounting seat 120 can be understood as the mounting seat 120 being roughly C-shaped, that is, the mounting seat 120 can be "∑"-shaped, the mounting seat 120 can also be "ㄈ"-shaped, or the mounting seat 120 can also be "C"-shaped. The specific shape of the mounting seat 120 is not limited here, as long as the mounting seat 120 has a lateral opening structure. The material strength of the mounting seat 120 is higher than the material strength of the supporting body 110. For example, the mounting seat 120 is made of metal material. The mounting seat 120 can be made of metal aluminum, metal iron, alloy and other metal materials with high strength, which are not specifically limited here; correspondingly, the supporting body 110 can be made of materials with relatively low material strength such as plastic. Taking plastic as an example, it is convenient to form complex shapes at a lower cost.

[0042] There are many ways to fix the mounting seat 120 and the support body 110. For example, the mounting seat 120 and the support body 110 can be fixedly connected by screws or bolts. Another example is that the mounting seat 120 and the support body 110 can be connected by a snap fastener. Another example is that the mounting seat 120 and the support body 110 can be fixedly connected by a clamp. The mounting seat 120 and the support body 110 can also be fixedly connected by other methods, which are not listed here one by one. It is worth noting that when the mounting seat 120 is fixedly connected to the support body 110, the upper mounting surface of the mounting seat 120 is in contact with the upper surface of the top plate 111 of the support body 110, and the lower mounting surface of the mounting seat 120 is in contact with the lower surface of the bottom plate 112 of the support body 110. This facilitates the installation of the mounting seat 120 and also increases the contact area between the mounting seat 120 and the support body 110, which helps to avoid the problem of excessive force concentration on the support body 110, causing deformation and even damage. In addition, since the roller 140 and the fixing rod 200 are both installed and connected to the mounting seat 120, the assembly is simplified, thereby making the use of the support seat 100 more convenient.

[0043] The connecting shaft 130 is arranged at the lower side of the mounting seat 120. There are two ways to connect the connecting shaft 130 and the mounting seat 120. One is that the connecting shaft 130 is fixedly connected to the mounting seat 120, that is, the connecting shaft 130 cannot rotate relative to the mounting seat 120 under the action of external force, and the other is that the connecting shaft 130 is rotationally connected to the mounting seat 120, that is, the connecting shaft 130 can rotate relative to the mounting seat 120 under the action of external force. There are also two ways to connect the roller 140 to the connecting shaft 130. When the connecting shaft 130 and the mounting seat 120 are fixedly connected, the roller 140 and the connecting shaft 130 are rotationally connected. When the connecting shaft 130 and the mounting seat 120 are rotationally connected, the roller 140 can be fixedly connected or rotationally connected to the connecting shaft 130. It is worth noting that after the roller 140 is assembled to the connecting shaft 130, the roller 140 is at least partially arranged to protrude from the lower surface of the base plate 112, so that the roller 140 can serve as a supporting point to support the entire support base 100, so that the support base 100 can slide smoothly on the ground or the supporting surface.

[0044] In the present invention, by setting the material strength of the mounting seat 120 to be stronger than the material strength of the supporting body 110, and at the same time, the mounting seat 120 is provided with an upper mounting surface that is in contact with the upper surface of the top plate 111 and a lower mounting surface that is in contact with the lower surface of the bottom plate 112, it is ensured that the contact area between the mounting seat 120 and the supporting body 110 is large enough, which can not only ensure that the positioning between the mounting seat 120 and the supporting body 110 is stable, but also ensure that the contact area between the mounting seat 120 and the supporting body 110 is large enough, thereby avoiding the problem of stress concentration caused by the small contact area between the supporting body 110 and the mounting seat 120, which in turn causes deformation or even damage of the supporting body 110.

[0045] See also Figure 2 and Figure 3 In some embodiments of the present invention, the mounting seat 120 includes an upper mounting plate 121, a lower mounting plate 122 and a connecting plate 123. The upper mounting plate 121 is located on the upper side of the top plate 111 and is fixedly connected to the top plate 111. The upper mounting plate 121 has an upper mounting surface (not marked) that fits the upper surface of the top plate 111. The lower mounting plate 122 is located on the lower side of the bottom plate 112 and is fixedly connected to the bottom plate 112. The lower mounting plate 122 has a lower mounting surface (not marked) that fits the lower surface of the bottom plate 112. The connecting plate 123 extends in the up-down direction and connects the upper mounting plate 121 and the lower mounting plate 122. This arrangement ensures that the mounting seat 120 is not easy to fall off from the supporting body 110.

[0046] Please also read Figure 4The surface of the connecting plate 123 facing away from the supporting body 110 is concavely provided with a mounting groove 120a, and the mounting groove 120a is also downwardly penetrated through the lower mounting plate 122, and the two ends of the connecting shaft 130 are respectively connected to the two groove walls of the mounting groove 120a that are opposite to each other, and the roller 140 is installed in the mounting groove 120a and connected to the connecting shaft 130, and the roller 140 also extends from the lower side of the mounting groove 120a. In this way, when carrying the supporting seat 100, the supporting body 110 can be tilted first and formed at a certain angle with the ground or the supporting surface, so that the center of gravity of the supporting body 110 is located above the roller 140, which not only facilitates the sliding of the supporting body 110, but also reduces the setting of the roller 140.

[0047] Further, two avoidance recesses 120b are concavely provided at the position where the connecting plate 123 is connected to the lower mounting plate 122, and the two avoidance recesses 120b are both arranged facing away from the side plate 113, and the two avoidance recesses 120b are respectively arranged at two opposite sides of the mounting groove 120a, and the positions of the two avoidance recesses 120b away from the mounting groove 120a are both concavely provided with mounting holes 120c, and the parts of the connecting shaft 130 located at both sides of the mounting groove 120a are respectively installed in the corresponding avoidance recesses 120b, and the two ends of the connecting shaft 130 are also respectively matched with the mounting holes 120c on the corresponding sides. Such a configuration not only facilitates the installation of the connecting shaft 130, but also constrains the two ends of the connecting shaft 130, especially when the support seat 100 stands on the ground or the support surface, the connecting shaft 130 fits more tightly with the two avoidance recesses 120b under the gravity of the supporting body 110.

[0048] See also Figure 1 , Figure 5 as well as Figure 6 The mounting seat 120 further includes a connecting column 124, which is disposed on the side of the connecting plate 123 facing the side plate 113, and the upper end of the connecting column 124 is connected to the upper mounting plate 121, and an assembly hole is disposed on the connecting column 124, and the assembly hole is disposed upwardly through the upper mounting plate 121. Such a configuration not only facilitates the connection between the mounting seat 120 and the fixing rod 200 of the display bracket 1000, but also ensures that the supporting body 110 is not directly connected to the fixing rod 200 of the display bracket 1000, thereby avoiding the problem of deformation of the supporting body 110 due to excessive force.

[0049] For further information, please also refer to Figure 7The surface of the side plate 113 facing the connecting plate 123 is concavely provided with a receiving groove 1131, which extends upward and penetrates the upper surface of the top plate 111, and extends downward and penetrates the lower surface of the bottom plate 112, and the receiving groove 1131 accommodates the connecting column 124. With such a configuration, on the one hand, the gap between the connecting plate 123 and the side plate 113 can be reduced, and when the receiving groove 1131 can completely accommodate the connecting column 124, the connecting plate 123 can be completely fitted with the side surface of the side plate 113, which can further improve the stability of the assembly between the mounting seat 120 and the supporting body 110; on the other hand, since the gap between the connecting plate 123 and the side plate 113 is reduced, the overall size of the supporting seat 100 in the horizontal direction can be reduced.

[0050] Furthermore, the mounting seat 120 further includes a reinforcing rib 125, which is disposed on the side of the connecting plate 123 facing the side plate 113, and the reinforcing rib 125 extends upward and is fixedly connected to the outer peripheral wall of the connecting column 124, and the reinforcing rib 125 is also respectively fixedly connected to the upper mounting plate 121 and the lower mounting plate 122. With such a configuration, on the one hand, the spacing between the upper mounting plate 121 and the lower mounting plate 122 can be limited by the configuration of the reinforcing rib 125, thereby ensuring that the upper mounting plate 121 and the lower mounting plate 122 are not easily deformed after being subjected to force; on the other hand, the strength of the connecting column 124 can also be improved.

[0051] Please refer to the figure, in some embodiments of the present invention, a plurality of first reinforcing ribs 126 are arranged at intervals along the axial direction of the connecting shaft 130 at the position where the upper mounting surface is connected to the connecting plate 123; and / or a plurality of second reinforcing ribs 127 are arranged at intervals along the axial direction of the connecting shaft 130 at the position where the lower mounting surface is connected to the connecting plate 123. Such a configuration can enhance the connection strength between the connecting plate 123 and the upper mounting plate 121 and the strength between the connecting plate 123 and the lower mounting plate 122, thereby ensuring that the mounting seat 120 as a whole is not easily deformed when subjected to external forces.

[0052] See also Figure 1 , Figure 7 as well as Figure 8In some embodiments of the utility model, the surface of the side plate 113 is recessed with a first avoidance groove 1132 extending in the up and down directions, the upper surface of the top plate 111 is recessed with a second avoidance groove 1111, and the lower surface of the bottom plate 112 is recessed with a third avoidance groove 1121. The upper end of the first avoidance groove 1132 is connected to the second avoidance groove 1111, and the lower end of the first avoidance groove 1132 is connected to the third avoidance groove 1121. The first avoidance groove 1132 is used to accommodate the connecting plate 123, the second avoidance groove 1111 is used to accommodate the upper mounting plate 121, and the third avoidance groove 1121 is used to accommodate the lower mounting plate 122. In this way, the upper surface of the upper mounting plate 121 can be flush with or lower than the upper surface of the top plate 111, the lower surface of the lower mounting plate 122 can be flush with or higher than the lower surface of the bottom plate 112, and the surface of the connecting plate 123 facing away from the side plate 113 is located in the first avoidance groove 1132 or is flush with the side surface of the side plate 113, thereby avoiding the mounting seat 120 protruding from the supporting body 110.

[0053] See also Figure 1 The utility model also provides a display stand 1000, which includes a fixing rod 200 of the display stand 1000 and a support base 100 of the display stand 1000, wherein the fixing rod 200 of the display stand 1000 is installed above the support base 100 of the display stand 1000. The specific structure of the support base 100 of the display stand 1000 refers to the above embodiment, and since the display stand 1000 adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0054] See also Figure 8 In some embodiments of the utility model, the support body 110 has two side plates 113 arranged opposite to each other, and one side plate 113 of the two side plates 113 is provided with two mounting parts 114, and the two mounting parts 114 are arranged at intervals in the extension direction of the corresponding side plates 113, and the two mounting parts 114 are respectively used to connect with the corresponding corners of the billboard; the number of the mounting seats 120 is two, and the two mounting seats 120 are fixedly connected to the support body 110 and are located on the same side of the side plates 113 away from the two mounting parts 114 in the two side plates 113, and the two mounting seats 120 are also arranged at intervals along the extension direction of the adjacent side plates 113; the fixed rod 200 of the display bracket 1000 includes two supporting vertical rods 210 and a supporting cross rod 220, the lower ends of the two supporting vertical rods 210 are connected to the corresponding mounting seats 120, and the upper ends of the two supporting vertical rods 210 are respectively connected to the supporting cross rod 220, and the supporting cross rod 220 is elastically and retractably arranged along the axial direction, and the two ends of the supporting cross rod 220 are used to connect with the corresponding corners of the billboard.

[0055] Based on the above technical solution, when hanging a billboard on the display bracket 1000, the two corners on the lower side of the billboard can be fixed on the corresponding mounting parts 114 respectively, and the two corners on the upper side of the billboard can be fixed on the corresponding ends of the supporting cross bar 220 respectively. Since the supporting cross bar 220 is elastically and retractably arranged along the axial direction, the entire billboard can be unfolded by adjusting the supporting cross bar 220, thereby ensuring that the billboard hung on the display bracket 1000 is fully unfolded, thereby improving the display effect of the billboard, and also making the display bracket 1000 adaptable to billboards of different sizes, expanding the scope of application of the display bracket 1000.

[0056] It is worth noting that there are many types of support crossbars 220. In some embodiments of the present invention, please refer to the figures. The support crossbar 220 includes a rod body 221, two sets of springs 222, two movable sleeves 223 and two limit members 224; wherein the rod body 221 is detachably connected to the support vertical rod 210 at a position between the left and right ends, and the left and right ends of the rod body 221 are both provided with movable grooves 2211, each movable groove 2211 includes a movable segment 2211a extending in the transverse direction and a limit segment 2211b connected to the movable segment 2211a and extending laterally; the two sets of springs 222 are respectively sleeved Provided at the end corresponding to the rod body 221, one end of the two sets of springs 222 is limited and kept relatively fixed with the rod body 221, and the other end of the two sets of springs 222 can move relative to the rod body 221 in the left and right directions; the two movable sleeves 223 are respectively sleeved on the outer sides of the corresponding ends of the rod body 221, and the two movable sleeves 223 can respectively rotate relative to the rod body 221, and the two movable sleeves 223 are also abutted against one end of the sleeve spring 222 that can move relative to the rod body 221; the two limiting members 224 are respectively installed on the corresponding movable sleeves 223, and the two limiting members 224 respectively pass through the corresponding movable sleeves 223 and cooperate with the corresponding movable grooves 2211.

[0057] Based on the above technical solution, the two movable sleeves 223 are respectively used to connect the hooks of the billboard. When the length of the supporting crossbar 220 needs to be increased, the two movable sleeves 223 only need to be rotated so that the limiting members 224 on the two movable sleeves 223 slide from the limiting segments 2211b of the corresponding movable grooves 2211 to the corresponding movable segments 2211a, respectively. The two movable sleeves 223 can move in the direction away from each other under the action of the corresponding sleeve springs 222 until the corresponding limiting member 224 abuts against a section of the corresponding movable segment 2211a away from the corresponding limiting segment 2211b, and the sleeve springs 222 still elastically support the corresponding movable sleeve 223.
