[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an electric explosion-proof actuator mechanism, which has the following beneficial effects:

[0017] This electric explosion-proof actuator mechanism has the electric actuator body completely inside two explosion-proof shells. The limiting block contacts the explosion-proof shell and compresses the spring. Through the elastic force of the spring, the two explosion-proof shells can be connected to each other, making it difficult for the two explosion-proof shells to slide on the base.

[0018] When it is necessary to operate the main body of the electric actuator, move the stop lever to make multiple stop levers in a vertical position. At this time, pull the explosion-proof shell to make the slider slide in the slide groove, so that the two explosion-proof shells slide on the base, which exposes the main body of the electric actuator, making it convenient to operate or maintain the main body of the electric actuator.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 The present invention provides an electric explosion-proof actuator mechanism, including a base 1, an electric actuator body 2 fixedly mounted on the upper end of the base 1, and two explosion-proof shells 3 symmetrically mounted on the upper end of the base 1, wherein the electric actuator body 2 can be located inside the two explosion-proof shells 3.

[0026] Two sliding grooves 4 are symmetrically arranged in the middle part of the base 1. The inner wall of the sliding groove 4 is provided with a guide groove. The lower end of the explosion-proof shell 3 is provided with a slider 5 that slides in cooperation with the sliding groove 4. The two ends of the slider 5 are provided with guide blocks 7 that slide in cooperation with the guide groove.

[0027] The upper end of the base 1 is symmetrically provided with multiple support rods 12 for the electric actuator body 2. The top of the support rod 12 is rotatably provided with a stop rod 13. The inner side of the stop rod 13 is provided with a cavity. The cavity is provided with a spring. One end of the spring is provided with a limiting block 15. The limiting block 15 can limit the explosion-proof shell 3 on the base 1.

[0028] In this embodiment, when the electric actuator body 2 is in use, the base 1 is fixed on the designated equipment so that the control line on the electric actuator body 2 is connected to the line on the equipment.

[0029] At this time, the electric actuator body 2 is completely inside the two explosion-proof shells 3. The stop lever 13 will be in a horizontal state, and multiple stop levers 13 are located on the outside of the explosion-proof shells 3 respectively. The limiting block 15 will contact the explosion-proof shells 3 and compress the spring. Through the elastic force of the spring, the two explosion-proof shells 3 can be connected to each other, making it difficult for the two explosion-proof shells 3 to slide on the base 1. This provides a protective effect for the electric actuator body 2, so that the electric actuator body 2 will not be exposed to the outside for a long time. The explosion-proof effect is good. When this structure is subjected to external force, the electric actuator body 2 is not easily damaged.

[0030] When it is necessary to operate the electric actuator body 2, move the stop lever 13 to make multiple stop levers 13 in a vertical state. At this time, pull the explosion-proof shell 3 to make the slider 5 slide in the slide groove 4, so that the two explosion-proof shells 3 can slide on the base 1, which can expose the electric actuator body 2, making it convenient to operate or maintain the electric actuator body 2.

[0031] In this embodiment, the bottom of the slider 5 is arc-shaped, and the guide block 7 is a cylindrical structure. The cylindrical guide block 7 slides more smoothly in the guide groove, thereby improving the smoothness of the slider 5 during sliding.

[0032] When the explosion-proof shell 3 is damaged, it needs to be disassembled. Two positioning holes 6 are symmetrically arranged at the bottom of the slider 5. The guide block 7 is provided with a positioning rod 8 that is inserted into the positioning hole 6. The positioning rod 8 is threaded with the positioning hole 6. The guide block 7 is provided with a groove 9. The groove 9 can be a slotted groove 9 or a cross groove 9. The guide block 7 can be rotated easily with a screwdriver. Through the cooperation between the positioning rod 8 and the positioning hole 6, the guide block 7 can be easily assembled and disassembled at both ends of the slider 5.

[0033] When the explosion-proof housing 3 is opened, the electric actuator body 2 is not open, making it difficult to repair. The base 1 has two symmetrical sliding grooves 4 at both ends, with two limiting brackets 10. The limiting brackets 10 have limiting grooves 11, which are connected to the guide groove. The guide block 7 can rotate inside the limiting groove 11. When the explosion-proof housing 3 slides to both ends of the base 1, the guide block 7 will enter the limiting groove 11. At this time, the guide block 7 can rotate inside the limiting groove 11, which makes the explosion-proof housing 3 below the base 1, making the electric actuator body 2 more open and convenient for repair.

[0034] In this structure, the two stop rods 13 are connected by a bent rod. The top of the stop rod 13 is provided with a positioning seat 14. The positioning seat 14 is rotatably connected to both ends of the bent rod. The bent rod facilitates the synchronous operation of the two stop rods 13 on one side of the electric actuator body 2.
