Description

Technical Field

[0001] The utility model relates to an electric valve actuator, in particular to an electric valve actuator with a locking mechanism. Background Technique

[0002] A valve electric actuator refers to a machine that uses electric energy as the main energy source to drive a valve. Since it is a precision electrical component, it generally has certain explosion-proof and protection level (waterproof and dustproof) requirements.

[0003] The utility model with the authorization announcement number CN211693705U relates to a valve electric actuator, including a housing. The housing fixedly connected includes an upper housing and a lower housing. A hexagonal wrench is provided on the lower housing, and a first groove for placing the hexagonal wrench is provided on the lower housing. A plurality of locking devices are provided in the first groove. It will not affect the installation and operation of the valve electric actuator, and it is more convenient to use. The locking device can effectively fix the hexagonal wrench in the first groove, and it is convenient to take and place, effectively improving the work efficiency. However, no shielding structure is provided on the first groove, resulting in rainwater flowing into it along the housing wall, making the hexagonal wrench prone to rust. Moreover, the hexagonal wrench is exposed to the environment, and impurities and dust in the air will accumulate in the first groove, making the first groove and the hexagonal wrench dirty, and it is particularly uncomfortable for the staff to use the hexagonal wrench. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electric valve actuator with a locking mechanism to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the utility model provides the following technical solution: An electric valve actuator with a locking mechanism includes an upper housing and a lower housing fixedly connected. A component groove for placing a hexagonal wrench is provided on the lower housing. The hexagonal wrench is locked in the component groove by a plurality of locking devices provided. A groove cover adapted to the structure of the component groove is installed on one side end of the component groove through a pin shaft.

[0006] Connection parts are provided on the peripheral sides of the component groove, and positioning parts are provided at the bottom of the groove cover. The groove cover is arranged on the component groove through the cooperation of the positioning parts and the connection parts.

[0007] A skirt plate is provided on the outer peripheral side of the groove cover.

[0008] A sealing gasket is provided at the bottom of the skirt plate.

[0009] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: on one side end of the component groove of the utility model, a groove cover adapted to the structure of the component groove is installed through a pin shaft. The groove cover can block rainwater from flowing into the component groove and also block impurities and dust in the air from entering the component groove, preventing rust and dirt on the hex wrench and in the component groove, and making it more comfortable for the staff to use the hex wrench.

[0015] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the utility model.

[0016] Please refer to Figures 1-3 , the utility model provides a technical solution: an electric valve actuator with a locking mechanism, including a fixedly connected upper shell 1 and a lower shell 2. A component groove 3 for placing a hex wrench is provided on the lower shell 2. The hex wrench is locked in the component groove 3 through a plurality of locking devices provided. A groove cover 4 adapted to the structure of the component groove 3 is installed on one side end of the component groove 3 through a pin shaft. The groove cover 4 can cover the component groove 3, so as to block rainwater or impurities in the air from flowing into or accumulating in the component groove 3, causing the hex wrench to rust and get dirty. Just pull the groove cover 4 hard to open it, and at this time, the hex wrench can be taken out.

[0017] A connecting portion 5 is provided on the peripheral side of the component groove 3, and a positioning portion 6 is provided at the bottom of the groove cover 4. The groove cover 4 is arranged on the component groove 3 through the cooperation of the positioning portion 6 and the connecting portion 5. Preferably, the connecting portion 5 is a magnet bar A, and the positioning portion 6 is a magnet bar B. The magnet bar B and the magnet bar A are firmly adsorbed to each other, so that the groove cover 4 is fastened to the component groove 3 by the magnetic adsorption between the magnet bars. At the same time, it is very convenient to open the groove cover 4, and only need to pull the groove cover 4 with force.

[0018] A skirt 7 is provided on the outer peripheral side of the groove cover 4. The presence of the skirt 7 can improve the effect of the groove cover 4 in blocking rainwater and sundries.

[0019] A sealing gasket 8 is provided at the bottom of the skirt 7. The sealing gasket 8 is preferably a silica gel gasket. Since the silica gel gasket has adhesiveness, it can be adhered to the outer side wall of the notch of the component groove 3, further improving the effect of the skirt 7 in blocking rainwater and sundries.
