Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to a novel electric actuator whose hand wheel is not easily touched by mistake. Background Art

[0002] Electric actuators are a commonly used automated mechanical device, often used to open and close valves. Existing electric actuators are usually equipped with a handwheel for manual control in emergencies or maintenance operations.

[0003] However, the handwheel on the existing electric actuator is exposed. When the electric mechanism inside the electric actuator is working, if a worker accidentally touches the handwheel, it is easy to damage the internal parts of the electric actuator and also easy to cause personal injury. Therefore, we propose a new electric actuator with a handwheel that is not easily touched by mistake, so as to protect the safety of the electric actuator and workers. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] As mentioned in the background art, the problem that the hand wheel is easily touched by mistake is addressed in the prior art.

[0024] The utility model provides a novel electric actuator with a hand wheel that is not easily touched by mistake.

[0025] Example 1

[0026] Reference Figures 1 to 3 A new electric actuator with a hand wheel that is not easily accidentally touched, comprising an electric actuator body 1, a mounting tube 2 provided at the bottom of the electric actuator body 1 for fixing the electric actuator body 1, and a hand wheel 3 provided at the top of the electric actuator body 1;

[0027] The rear side of the electric actuator body 1 is fixed with a mounting plate 4 by screws, and a guide rod 5 is provided on the top of the mounting plate 4;

[0028] A sleeve 6 is sleeved on the guide rod 5, and the sleeve 6 can be raised and lowered by the guide rod 5. A fixed cover 7 is provided on the front side of the sleeve 6. The fixed cover 7 is used to cover the hand wheel 3. The fixed cover 7 can be raised and lowered by the sleeve 6 to adjust the height. When it is at a low position, it just covers the hand wheel 3 to prevent the hand wheel 3 from being accidentally touched. When it is at a high position, it does not affect the use of the hand wheel 3.

[0029] The guide rod 5 is provided with two sockets 8;

[0030] The sleeve 6 is provided with a plug-in assembly for plugging into one of the sockets 8 .

[0031] The plug-in assembly includes a spring 9, which is connected to the sleeve 6. The front end of the spring 9 is connected to a T-shaped plug rod 10. The rear end of the plug rod 10 passes through the front side of the sleeve 6 and is inserted into one of the sockets 8. The plug rod 10 is located above the fixed cover 7 and does not affect the pulling of the plug rod 10.

[0032] By pulling the insertion rod 10 , the insertion rod 10 can be separated from the insertion hole 8 , and by loosening the insertion rod 10 , the insertion rod 10 can be driven to be inserted into another insertion hole 8 under the return elastic force of the spring 9 .

[0033] In order to facilitate lifting and lowering of the fixed cover 7 , a handle 11 is provided on the side of the fixed cover 7 .

[0034] A support sleeve 12 is provided on the guide rod 5, and a limiting sleeve 13 is provided on the sliding sleeve of the guide rod 5. The support sleeve 12 is located below the limiting sleeve 13. The limiting sleeve 13 is provided with a bolt 14 connected to the guide rod 5. The limiting sleeve 13 is fitly connected to the top of the sleeve 6. The limiting sleeve 13 can be disassembled through the bolt 14, thereby not affecting the disassembly and assembly of the sleeve 6 and the fixed cover 7.

[0035] When the fixed cover 7 is moved downward, when the sleeve 6 is blocked by the support sleeve 12 and cannot move further downward, the insertion rod 10 is aligned with the bottom socket 8. Similarly, when the sleeve 6 is blocked by the limit sleeve 13 and cannot move further upward, the insertion rod 10 is aligned with the top socket 8, thereby making it more convenient to adjust the height of the fixed cover 7.

[0036] Example 2

[0037] Reference Figures 1 to 3 A buffer cover 15 is sleeved on the outside of the fixed cover 7. The buffer cover 15 is made of rubber material, which can improve the strength of the fixed cover 7 when it is accidentally hit. The insertion rod 10 is located above the top of the buffer cover 15, which also does not affect the pulling of the insertion rod 10.

[0038] The rest of the structure is the same as that of Example 1.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
