Description

Technical Field

[0001] The utility model relates to the technical field of display screen box accessories, and particularly relates to an arc locking mechanism applied to a display screen box. Background Art

[0002] LED screens have good energy-saving effects and longer service lives. When the lamp beads are well encapsulated and the lamps are well assembled, LED screens have good dustproof and waterproof effects and can adapt to outdoor working environments. Therefore, they are commonly used in outdoor lamps, light boxes, and advertising screens. In some large-size advertising screens, the length or width dimension can reach several meters or dozens of meters. For such LED screens, it is almost impossible to directly produce and manufacture them. Usually, the method is to splice small module display screen boxes into a large display screen. When the advertising plane is installed on urban streets and pedestrians watch the advertisement in front of the large screen, the distance from the person to the middle of the large screen is less than the distance from the person to the edge of the large screen, and there is a large distance gap, which easily causes the picture in the field of vision to be severely distorted or occasionally twisted, seriously reducing the viewing experience of pedestrians in front of the large screen and affecting the advertisement playback. In addition, in many cases, the places where the screens are installed vary in size, curvature, straightness, and even column structures, special-shaped structures, etc. The existing screen splicing methods are single, and there are deficiencies in installation adaptability. Therefore, an arc locking mechanism applied to a display screen box is provided to solve the above problems. Content of the Utility Model

The engaging component 14 movably passes through the fixed arm main body 111 through the through holes 1111, and the movement conditions of the first telescopic arm assembly 12 and the second telescopic arm assembly 13 in the fixed arm assembly 11 can be conveniently observed through the two observation holes 1112 respectively; at least one guide seat 1121 is arranged on the cover plate 112, and the movement of the engaging component 14 is guided through at least one guide seat 1121; the first connection seat 113 is fixed on the side of the fixed arm main body 111 through the first fastening screw 1131, and at least one first fixing hole 1132 is arranged through it, and the fixed arm assembly 11 is fixedly installed on the back of the flexible display screen box through at least one first fixing hole 1132.

[0030] Please refer to Figures 1-5 As shown, in this embodiment, the first telescopic arm assembly 12 includes a telescopic arm main body 121 and a second connection seat 122; one end of the telescopic arm main body 121 is slidably arranged in the fixed arm assembly 11 and can be detachably engaged with the engaging component 14, and one end of the telescopic arm main body 121 is fixedly arranged in the fixed arm assembly 11 through the engaging component 14; the second connection seat 122 is fixedly arranged on one side of the telescopic arm main body 121, and the first telescopic arm assembly 12 is fixedly installed on the back of the flexible display screen box through the second connection seat 122.

[0031] Please refer to Figure 5As shown, specifically, a guide cavity 1211 is provided through the telescopic arm body 121, and the engaging component 14 moves through the telescopic arm body 121 via the guide cavity 1211; multiple slots 1212 are evenly and equidistantly arranged on one side of the guide cavity 1211, and the engaging component 14 can be detachably engaged in the multiple slots 1212 respectively, thereby realizing the engaging and fixed connection of the first telescopic arm component 12 and the fixed arm component 11; the telescopic arm body 121 is also provided with a mark 1213, the position of the mark 1213 corresponds to the position of the corresponding observation hole 1112, and the user observes the number on the mark 1213 through the observation hole 1112, thereby facilitating the user to perform precise adjustment operation of the first telescopic arm component 12 relative to the fixed arm component 11.

[0032] Please see Figures 1-4 As shown, in this embodiment, the structure of the second telescopic arm assembly 13 is similar to that of the first telescopic arm assembly 12, so its specific structure will not be described in detail here.

[0033] Please see Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the engaging assembly 14 includes an engaging shaft structure 141 and a handle structure 142. The engaging shaft structure 141 is movably disposed in the fixed arm assembly 11 and can be detachably engaged with the first telescopic arm assembly 12 and the second telescopic arm assembly 13 simultaneously. The handle structure 142 is connected to the engaging shaft structure 141 through a through hole 1111 in the fixed arm assembly 11. The handle structure 142 drives the engaging shaft structure 141 to move, so that the engaging shaft structure 141 simultaneously disengages from the engaging connection with the first telescopic arm assembly 12 and the second telescopic arm assembly 13, thereby allowing the first telescopic arm assembly 12 and the second telescopic arm assembly 13 to slide relative to the fixed arm assembly 11, realizing the telescopic operation of the arc-shaped locking mechanism 10.

[0034] Please see Figure 4 and Figure 6As shown, in this embodiment, the engaging shaft structure 141 includes a movable shaft 1411, a first fixing pin 1412, a second fixing pin 1413, an elastic element 1414, a first locking pin 1415, and a second locking pin 1416. The movable shaft 1411 is movably mounted on at least one guide seat 1121, and the movement of the movable shaft 1411 is guided by the at least one guide seat 1121. The first fixing pin 1412 and the second fixing pin 1413 are respectively fixedly mounted through the movable shaft 1411, and the handle structure 142 is connected to the movable shaft 1411 via the first fixing pin 1412. The elastic element 1414 passes through... A spring is inserted through the movable shaft 1411, with its two ends respectively contacting and connecting to the second fixing pin 1413 and the corresponding guide seat 1121. Its function is to provide a restoring force to the movable shaft 1411 and a clamping force to the first locking pin 1415 and the second locking pin 1416. The first locking pin 1415 and the second locking pin 1416 are respectively fixedly inserted through both ends of the movable shaft 1411, and can respectively engage in the corresponding slots 1212 on the first telescopic arm assembly 12 and the second telescopic arm assembly 13, thereby allowing the first telescopic arm assembly 12 and the second telescopic arm assembly 13 to be synchronously engaged and fixedly connected to the fixed arm assembly 11. Specifically, the elastic element 1414 is a spring, with buffer elements 14141 at both ends, which are connected to the second fixing pin 1413 and the corresponding guide seat 1121 respectively.

[0035] Please see Figure 4 and Figure 6 As shown, specifically, the handle structure 142 includes a rotating shaft 1421 and a handle body 1422; the two ends of the rotating shaft 1421 are respectively disposed on the fixed arm assembly 11; the handle body 1422 is rotatably disposed on the fixed arm assembly 11 via the rotating shaft 1421 and is connected to the first fixed pin 1412 via the through hole 1111.

[0036] It should be noted that the specific working process of the arc-shaped locking mechanism 10 applied to the display screen cabinet of this utility model is as follows: When the arc-shaped locking mechanism 10 needs to be extended and retracted, the handle body 1422 is forcefully turned to drive the movable shaft 1411 to move upward, so that the first locking pin 1415 and the second locking pin 1416 fixedly set at both ends of the movable shaft 1411 disengage from the corresponding slots 1212, thereby allowing the first telescopic arm assembly 12 and the second telescopic arm assembly 13 to slide relative to the fixed arm assembly 11, realizing the extension and retraction operation of the arc-shaped locking mechanism 10. When the movable shaft 1411 moves upward, it will compress the elastic element 1414, so that the elastic element 1414 accumulates elastic restoring force.

[0037] When the positions of the first telescopic arm assembly 12 and the second telescopic arm assembly 13 are adjusted, the handle body 1422 is returned to its initial position. Under the combined action of the elastic restoring force of the elastic element 1414 and the force of the handle body 1422, the movable shaft 1411 returns to its initial position, thereby causing the first locking pin 1415 and the second locking pin 1416, which are fixedly disposed at both ends of the movable shaft 1411, to engage in the corresponding slots 1212. At the same time, under the action of the elastic element 1414, a clamping force is provided to the first locking pin 1415 and the second locking pin 1416, so that the first locking pin 1415 and the second locking pin 1416 are securely engaged in the corresponding slots 1212.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
