[0038] As Figure 1 - Figure 2As shown in the figure, an embodiment of the present utility model provides a connecting mechanism for connecting a first component and a second component, including: a rotating part 11, a fixing part 12, and a connecting part 13. The rotating part 11 is connected to an inner side of the first component. The rotating part 11 is sleeved on the fixing part 12 and rotates around the axis direction of the fixing part 12. One end of the connecting part 13 is connected to the fixing part 12, and the other end is connected to an inner side of the second component.

[0039] By designing that the rotating part 11 is sleeved on the fixing part 12, and at the same time, the rotating part 11 is arranged on an inner side of the first component, the fixing part 12 is connected to one end of the connecting part 13, and the other end of the connecting part 13 is arranged on an inner side of the second component, thus connecting the first component and the second component together, that is, the rotating part 11 and the connecting part 13 are respectively arranged on an inner side of the first component and the second component. This kind of structural design is simple, without cumbersome installation steps, and is convenient for the staff to install; at the same time, the rotating part 11 can freely rotate around the axis direction of the fixing part 12, enabling the first component to freely open and close relative to the second component, which is convenient for subsequent opening of the first component and the second component for maintenance.

[0040] Exemplarily, in the initial installation state, the first component is vertically installed relative to the second component. The rotating part 11 is arranged on an inner side of the first component, and the connecting part 13 is arranged on an inner side of the second component, that is, the first component and the second component are connected together through the connecting mechanism 1. In this state, the first component is in a fully open state relative to the second component; move the first component closer to the second component. At this time, the first component drives the rotating part 11 to rotate 90° around the axis direction of the fixing part 12 until the first component fits the second component. In this state, the first component is in a fully closed state relative to the second component; move the first component away from the second component. At this time, the first component drives the rotating part 11 to rotate in the reverse direction around the axis direction of the fixing part 12, realizing the process of opening the first component relative to the second component. This kind of structural design can realize the opening and closing between the first component and the second component in a narrow space. During subsequent maintenance, there is no need to disassemble and inspect the whole device, and only need to open it to carry out maintenance work, which greatly facilitates subsequent maintenance operations.

[0041] Exemplarily, the rotating part 11 is welded to an inner side of the first component by welding.

[0042] Such as Figure 1As shown, in some embodiments of the present utility model, the fixing part 12 includes a first fixing block 121, a second fixing block 122 and a fixed shaft 123.

Both the first fixing block 121 and the second fixing block 122 are connected to the connecting part 13. The first fixing block 121, the rotating part 11 and the second fixing block 122 are all provided with through holes, and are sequentially sleeved on the fixed shaft 123 through the through holes. For example, the first fixing block 121 and the second fixing block 122 are fixed to the fixed shaft 123 by an open circlip. That is, the first fixing block 121 and the second fixing block 122 are immovable relative to the fixed shaft 123, and the rotating part 11 is capable of freely rotating relative to the fixed shaft 123.

[0043] As Figure 1 shown, in some embodiments of the present utility model, the connecting part 13 includes a first connecting piece 131 and a second connecting piece 132. The first connecting piece 131 and the second connecting piece 132 are orthogonally arranged. That is, the first connecting piece 131 is perpendicular to the second connecting piece 132. It should be noted that the first connecting piece 131 and the second connecting piece 132 can be designed as an integral structure or a split structure. If designed as a split structure, the first connecting piece 131 and the second connecting piece 132 are orthogonally fixedly connected to form an L-shaped opening.

[0044] As Figure 1 and Figure 2 shown, in some embodiments of the present utility model, a first through hole 14 is provided on the first connecting piece 131. A second through hole 15 is provided on the second connecting piece 132. The first connecting piece 131 is respectively connected to the first fixing block 121 and the second fixing block 122 by passing a first fastener 16 through the first through hole 14. The second connecting piece 132 is connected to the inner side of the second component by passing a second fastener 17 through the second through hole 15. Exemplarily, both the first fastener 16 and the second fastener 17 are screws.

That is, the first component is the mounting mechanism 2, and the second component is the box body 3.

[0046] The mounting mechanism 2 includes a frame body 21. The rotating part 11 is arranged on one inner side of the frame body 21.

One end of the connecting part 13 is connected to the fixed part 12, and the other end is connected to one inner side of the box body 1.

[0047] Since the rotating part 11 is arranged on one inner side of the frame body 21 and sleeved on the fixed part 12, the fixed part 12 is connected to one end of the connecting part 13, and the other end of the connecting part 13 is arranged on one inner side of the box body 1, the mounting mechanism 2 and the box body 3 are connected together. This kind of structural design is simple, without cumbersome installation steps, and is convenient for the staff to install; and the connecting mechanism 1 is arranged inside the mounting mechanism 2 and the box body 3, avoiding the risk of being easily damaged when placed outside, and improving the safety of the chassis during use; at the same time, the rotating part 11 can freely rotate around the axis direction of the fixed part 12, and the mounting mechanism 2 drives the rotating part 11 to rotate relative to the fixed part 12, so as to realize the opening and closing between the mounting mechanism 2 and the box body 3.

[0048] It should be noted that the number of the connecting mechanisms 1 can be used according to the specific sizes of the mounting mechanism 2 and the box body 3. For example, two connecting mechanisms 1 are selected to connect a mounting mechanism 2 and the box body 3.

[0049] As Figure 2 shown, in some embodiments of the present invention, two mounting mechanisms 2 are respectively arranged on both sides of the box body 3. Compared with the single-sided display of the prior art, two display mechanisms are respectively installed by using two mounting mechanisms 2 to realize double-sided display, which is very suitable for specific scenarios such as tunnels that require double-sided display, and expands the applicable range of scenarios.

Specifically, the upper frame 211, the left frame 212, the lower frame 213, and the right frame 214 are welded into a rectangular frame 21 by laser welding. The rotating part 11 is arranged inside the left frame 212. For the inner side of the left frame 212, it can be specifically designed according to specific situations. For example, the side of the left frame 212 is designed as a C shape, and the connecting mechanism 1 is placed in the inner cavity formed by the C shape, facilitating the opening and closing of the frame 21 relative to the box body main body 31. Exemplarily, the rotating part 11 is welded to the inner side of the left frame 212. It should be noted that the shape of the frame 21 is not specifically limited and should be specifically designed according to actual needs.

[0056] As Figure 2 and Figure 5 shown in the figure, in some embodiments of the present utility model, the chassis for a display device further includes a locking member 5. The locking member 5 is disposed on the other side of the box body 31. Specifically, the locking member 5 is fixedly installed on the left side plate 312 and / or the right side plate 314.

[0058] As Figure 1 - Figure 6As shown, the display device is, for example, a lane indicator, which is used to indicate road traffic information to drivers on the road. The chassis is installed on both sides of the box body 1 by two installation mechanisms 2 respectively, realizing double-sided display and expanding the usage scenarios of the chassis. Each installation mechanism 2 is connected to the box body 1 through a connection mechanism 1 to realize the opening and closing action. The specific installation steps are as follows, taking one of the installation mechanisms 2 as an example:

[0059] Step S1: Assemble the connection mechanism 1. Specifically, sequentially pass the first fixing block 121, the rotating part 11, and the second fixing block 122 into the fixed shaft 123. The rotating part 11 can rotate relative to the fixed shaft 123, and the first fixing block 121 and the second fixing block 122 are fixed relative to the fixed shaft 123; use the first fastener 16 to pass through the first through hole 14 to fasten the first connecting piece 131 to the first fixing block 121 and the second fixing block 122, thereby completing the assembly of the connection mechanism 1.

[0060] Step S2: Connect the assembled connection mechanism 1 to the box body 3. Specifically, use the second fastener 17 to pass through the second through hole 15 to fasten the second connecting piece 132 to the left side plate 312, thereby fixedly installing the connecting part 13 on the inner side of the left side plate 312 of the box body 3.

[0061] Step S3: Connect the assembled connection mechanism 1 to the installation mechanism 2. Specifically, weld the rotating part 11 to the inner side of the left frame 212 of the frame body 21, thereby connecting the connection mechanism 1 to the installation mechanism 2.

[0062] It should be noted that the above installation steps are only examples, and no specific limitation is made on the installation sequence.

[0063] It should be noted that the up, down, left, and right in this article correspond to the up, down, left, and right in the corresponding drawings.

[0064] To sum up, since most of the chassis of lane indicators are installed in the form of external hinges, it is easy to be damaged by the outside world, and the connection structure in the prior art is complex and difficult to install, and subsequent maintenance is also very inconvenient. At the same time, limited by single-sided display, it is difficult to be widely applicable. In view of the above technical problems, the utility model designs a connection mechanism with a simple structure, places the connection mechanism inside the installation mechanism and the box body respectively, which not only plays the role of connecting the installation mechanism and the box body, but also can realize the free opening and closing of the installation mechanism relative to the box body. The chassis for the display device provided by the utility model has a flat overall appearance and a simple structure. Compared with the previous lane indicators, it is more convenient to install and is convenient for subsequent maintenance, minimizing the impact on road traffic during the daily maintenance process of the lane indicator to the greatest extent. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0065] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model.
