DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1 , Figure 2 As shown, an electric actuator for a ball valve comprises an actuator body 1 and a mounting box 2. The upper end surface of the mounting box 2 is provided with a year display area 3, a month display area 4 and a date display area 5.

[0023] like Figure 2 , Figure 3 , Figure 4 As shown, a rotating shaft 21 is horizontally arranged in the installation box 2, and a plurality of rollers 22 are arranged on the rotating shaft 21. Display numbers 23 are evenly arranged on the outer walls of the rollers 22. A friction rod 24 located between two adjacent display numbers 23 is arranged on the surface of the rollers 22, so that the rotation process of the rollers 22 is more convenient.

[0024] like Figure 2 , Figure 3 , Figure 4 As shown, the outer edge positions of the plurality of rollers 22 pass through the year display area 3 , the month display area 4 and the date display area 5 , and a locking mechanism 6 for fixing the rollers 22 is provided in the installation box 2 .

[0025] like Figure 2 , Figure 3 , Figure 4 As shown, the locking mechanism 6 includes a locking rod 61, a pull ring 62, a tension spring 63, a vertical rod 64 and a locking block 65. The locking rod 61 is horizontally slidably connected to the installation box 2, the pull ring 62 is arranged at the outer end of the locking rod 61, and the tension spring 63 is arranged between the inner end of the locking rod 61 and the inner wall of the installation box 2.

[0026] like Figure 2 , Figure 3 , Figure 4 As shown, the number of vertical rods 64 is the same as the number of rollers 22, and they are vertically arranged on the locking rod 61 and located beside the roller 22. The locking block 65 is arranged on the side wall of the vertical rod 64, and the side wall of the roller 22 is provided with a circle of locking holes 66 for the locking block 65 to be embedded.

[0027] When it is necessary to record the maintenance time, the locking rod 61 is pulled to slide outward, and the locking rod 61 drives the vertical rod 64 and the locking block 65 to move synchronously, and the locking block 65 is disengaged from the locking hole 66. Then, the rollers 22 in the year display area 3, the month display area 4 and the date display area 5 are controlled to rotate, and the required display numbers 23 on the rollers 22 are exposed outside the installation box 2, so as to adjust the positions of the year display area 3, the month display area 4 and the date display area 5.

[0028] Finally, the pull ring 62 is loosened, and the locking rod 61 moves in the opposite direction under the tension of the tension spring 63. At this time, the locking rod 61 drives the vertical rod 64 and the locking block 65 to move synchronously, and the locking block 65 is inserted into the locking hole 66 to lock and fix all the rollers 22 to prevent accidental touch from affecting the recording time.

[0029] Therefore, by setting up a rotating display device, after the maintenance is completed, the roller 22 is controlled to rotate to achieve separate adjustment and recording of the year, month and date, so that the last maintenance time can be accurately known at the next maintenance without worrying about forgetting or losing, thereby achieving the effect of conveniently recording the maintenance time.

[0030] like Figure 2 As shown, the installation box 2 includes a bottom box 25 and a top box 26. The top box 26 is vertically provided with hooks 27 around it, and the bottom box 25 is provided with a hook hole 28 for the hook 27 to pass through. Therefore, by providing an installation box 2 that is easy to disassemble and assemble, the installation box 2 can be quickly processed, and the internal components of the installation box 2 can also be quickly repaired and replaced.

[0031] like Figure 2 , Figure 5 As shown, a pair of clamping plates 7 for clamping both sides of the actuator body 1 are provided on the lower end surface of the bottom box 25, and a suction cup 71 is provided on the inner side of the clamping plates 7. The clamping plates 7 are horizontally slidably connected to the bottom box 25, and a driving mechanism 8 for controlling the sliding movement of the clamping plates 7 is provided in the bottom box 25.

[0032] like Figure 5 As shown, the driving mechanism 8 includes a bidirectional screw 81, a driving block 82 and a hand wheel 83. The bidirectional screw 81 is horizontally rotatably connected to the bottom box 25. The driving block 82 is horizontally slidably connected to the bottom box 25 and connected to the upper end of the clamping plate 7. The hand wheel 83 is arranged at the outer end of the bidirectional screw 81.

[0033] When the installation box 2 needs to be installed and fixed, select any actuator body 1, wipe any two parallel surfaces of the actuator body 1, and then control the hand wheel 83 to drive the bidirectional screw 81 to rotate and move the pair of clamps 7 away from each other. Then place the installation box 2 on the actuator body 1, and make the clamps 7 on both sides of the two parallel surfaces, and then control the hand wheel 83 to drive the bidirectional screw 81 to rotate in the opposite direction and move the pair of clamps 7 closer to each other. Finally, under the attraction of the suction cup 71 and the clamping action of the clamp 7, the installation box 2 is firmly fixed on the actuator body 1, and can be adapted to different actuators, achieving the advantage of high practicality.

[0034] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
