Description

Technical Field

[0001] This utility model relates to the field of dome screen shell printing technology, specifically, to a clamping mechanism for dome screen shell printing. Background Technology

[0002] An LED dome screen is a special display technology that uses LEDs (light-emitting diodes) as display units to construct a spherical screen to display images or videos. This type of dome screen can provide an immersive viewing experience because it can display content from all angles, making the audience feel as if they are surrounded by images. Because the dome screen is spherical, its outer shell is also spherical or curved.

[0003] The printing and processing of the dome screen shell requires ensuring its stability. However, the commonly used clamping mechanisms are not suitable for dome screen shells, which can easily cause difficulties in clamping the shell or cause deformation due to improper clamping, thus affecting the quality of the dome screen shell. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a clamping mechanism for printing on the shell of a dome screen, so as to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] A clamping mechanism for printing on the shell of a dome screen includes a clamping base, a support rod mounted on the top of the clamping base, a pneumatic telescopic rod fixedly mounted on the top of the support rod, a sleeve fixedly connected to the top of the support rod, a linkage rod slidably mounted on the inner side of the sleeve, a first clamping plate evenly distributed on the sleeve, the first clamping plate being connected to an adjacent linkage rod, a second clamping plate fixedly mounted on the sleeve, and the output end of the pneumatic telescopic rod being fixedly connected to one end of the linkage rod.

[0007] The number of support rods is two, and the bottom of the clamping seat is provided with an annular groove. The bottom ends of the two support rods extend to the inner side of the annular groove and are slidably connected to the inner wall of the annular groove.

[0008] As a further description of the above technical solution:

[0009] The first clamping plate consists of a transmission wheel and a clamping rod fixedly connected to the transmission wheel. The transmission wheel has evenly distributed tooth grooves, and the linkage rod meshes with the transmission wheel through the tooth grooves.

[0010] As a further description of the above technical solution:

[0011] The support rod has a strip-shaped through groove, and an arc-shaped support bar is hinged to the inner side of the strip-shaped through groove. An adjusting screw is inserted through the support rod and is inserted through the inner side of the arc-shaped support bar.

[0012] As a further description of the above technical solution:

[0013] The arc-shaped support bar has an arc-shaped through groove, and the adjusting screw is located inside the arc-shaped through groove.

[0014] As a further description of the above technical solution:

[0015] A fixing screw is threaded onto the support rod, and the bottom end of the fixing screw contacts the clamping seat.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This solution utilizes the connection between the first clamping plate and the adjacent linkage rod to control the angle of the first clamping plate until the first clamping plate and the second clamping plate cooperate to clamp and fix the dome shell. The clamping devices on the two support rods can be used to fix different positions of the dome shell, thereby improving the clamping stability and reliability of the dome shell and facilitating subsequent processing of the dome shell.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0024] Please see Figure 1-3In this utility model, a clamping mechanism for printing on the shell of a dome screen includes a clamping base 1, a support rod 2 installed on the top of a support rod 2, a pneumatic telescopic rod 3 fixedly installed on the top of the support rod 2, a sleeve 4 fixedly connected to the top of the support rod 2, a linkage rod 5 slidably installed on the inner side of the sleeve 4, a first clamping plate 6 evenly distributed hinged on the sleeve 4, the first clamping plate 6 being connected to the adjacent linkage rod 5, a second clamping plate 7 fixedly installed on the sleeve 4, and the output end of the pneumatic telescopic rod 3 being fixedly connected to one end of the linkage rod 5.

[0025] There are two support rods 2. The bottom of the clamping seat 1 is provided with an annular groove 8. The bottom ends of the two support rods 2 extend to the inner side of the annular groove 8 and slide to connect with the inner wall of the annular groove 8.

[0026] In this invention, by placing the dome shell above the support rod 2 and inserting the first clamping plate 6 into the interior of the dome shell frame, the pneumatic telescopic rod 3 can move the linkage rod 5 and the sleeve 4 internally. By utilizing the connection between the first clamping plate 6 and the adjacent linkage rod 5, the angle of the first clamping plate 6 can be controlled until the first clamping plate 6 and the second clamping plate 7 cooperate to clamp and fix the dome shell.

[0027] The clamping devices on the two support rods 2 can be used to fix different positions of the dome shell, thereby improving the clamping stability and reliability of the dome shell and facilitating subsequent processing of the dome shell.

[0028] Please see Figure 1 and Figure 2 The first clamping plate 6 is composed of a transmission wheel 61 and a clamping rod 62 fixedly connected to the transmission wheel 61. The transmission wheel 61 has evenly distributed tooth grooves, and the linkage rod 5 meshes with the transmission wheel 61 through the tooth grooves.

[0029] In this invention, the linkage rod 5 slides through the tooth groove and the transmission wheel 61, which can drive the transmission wheel 61 to deflect, thereby adjusting the angle of the first clamping plate 6.

[0030] Please see Figure 1 The support rod 2 has a strip-shaped through groove 21, and an arc-shaped support bar 22 is hinged to the inner side of the strip-shaped through groove 21. An adjusting screw 23 is inserted through the support rod 2 and is inserted through the inner side of the arc-shaped support bar 22.

[0031] In this invention, the arc-shaped support bar 22 is fixed by adjusting the screw 23, and the protruding part of the arc-shaped support bar 22 on the arc-shaped through groove 24 supports the airborne part of the dome shell, thereby reducing the burden on the top clamping device.

[0032] Please see Figure 1Among them, the arc-shaped support bar 22 is provided with an arc-shaped through groove 24, and the adjusting screw 23 is located inside the arc-shaped through groove 24.

[0033] In this invention, the positions of the adjusting screw 23 and the arc-shaped through groove 24 can be adjusted according to needs, thereby changing the protruding height and shape of the arc-shaped support bar 22, so as to adaptably support the dome screen shell.

[0034] Please see Figure 1 and Figure 3 Among them, the support rod 2 is threaded with a fixing screw 9, and the bottom end of the fixing screw 9 is in contact with the clamping seat 1.

[0035] In this invention, the friction between the fixing screw 9 and the clamping seat 1 can fix the position of the support rod 2 on the clamping seat 1, preventing the support rod 2 from sliding freely inside the annular groove 8.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
