Description

Technical Field

[0001] The utility model relates to the technical field of electric actuator turntables, in particular to a detachable and installable turntable for an electric actuator. Background Art

[0002] An electric actuator refers to an electric actuator mechanism, which is a driving device that can provide linear or rotational motion. It uses electric energy as the driving energy and works under the action of a certain control signal. It converts electric energy into a driving effect through a motor. Its basic types include three driving methods: partial rotation, multi-rotation, and linear stroke.

[0003] The most important structure and working form of an electric actuator is generally to drive the motor to work through electric energy, and then the motor drives the output end of the electric actuator. Finally, the output end outputs the drive in a rotational manner to complete the function of the electric actuator. In order to avoid the situation that the electric actuator cannot work when there is no power, a turntable is generally provided. The turntable is used for manual rotation to drive the output end of the electric actuator by manual rotation for emergency.

[0004] However, the existing electric actuator turntables are generally fixed to the connecting shaft of the output end of the electric actuator by several bolts. When it is necessary to replace the damaged turntable, it is necessary to use tools to disassemble the bolts one by one. The operation is cumbersome, the disassembly efficiency is slow, and it is inconvenient to replace the turntable. Summary of the Utility Model

[0027] Embodiment 1

[0028] Referring to Figure 1-7 , the first embodiment of the present utility model provides a detachable and installable turntable for an electric actuator, which mainly includes:

[0029] The main body structure 100, the main body structure 100 includes a turntable body 101 and a first connecting sleeve 102 fixedly connected to the bottom of the turntable body 101;

[0030] The positioning structure 200, the positioning structure 200 is located at the bottom of the first connecting sleeve 102, the positioning structure 200 includes a second connecting sleeve 201 symmetrically arranged up and down with the first connecting sleeve 102 and a pair of arc-shaped plates 202 symmetrically fixed to the top of the second connecting sleeve 201, and both pairs of arc-shaped plates 202 are movably connected to the first connecting sleeve 102;

[0031] The fixing structure 300, the fixing structure 300 is used to fixedly connect the first connecting sleeve 102 and the second connecting sleeve 201 together by limiting a pair of arc-shaped plates 202.

[0032] Specifically, the first connecting sleeve 102 has an inverted "T" - shaped structure, the second connecting sleeve 201 has a "T" - shaped structure, and both the first connecting sleeve 102 and the second connecting sleeve 201 are adapted to the connecting shaft on the electric actuator. That is, when installing the turntable, the first connecting sleeve 102 and the second connecting sleeve 201 are nested outside the connecting shaft. A pair of arc - shaped through - grooves 103 communicating up and down are opened at the bottom of the first connecting sleeve 102, and a pair of arc - shaped plates 202 are respectively inserted into the pair of arc - shaped through - grooves 103 in a matching manner.

[0033] Specifically, a plurality of bolt holes 203 are arranged in a circumferential array on the circumferential side of the small - diameter section of the second connecting sleeve 201. The second connecting sleeve 201 is fixedly connected to the connecting shaft on the electric actuator through the bolt holes 203 and bolts. After the fixed connection, when replacing the turntable body 101 in the later stage, it is not necessary to disassemble the bolts here.

[0034] Specifically, arc-shaped slots 204 are provided at both ends of a pair of arc-shaped plates 202 above the arc-shaped through groove 103, and the fixing structure 300 is connected to the arc-shaped slots 204;

[0035] There are a pair of fixing structures 300, which are respectively arranged between the two ends of a pair of arc-shaped plates 202. The fixing structure 300 includes an arc-shaped tube 301 that is movably attached to the top of the large-diameter section of the first connecting sleeve 102, a pair of arc-shaped insertion rods 302 that are respectively slidably connected to the inner parts of both ends of the arc-shaped tube 301, and an elastic member 303 fixedly connected to the opposite side of the pair of arc-shaped insertion rods 302. The elastic member 303 is arranged inside the arc-shaped tube 301 and is slidably connected to the arc-shaped tube 301. The mutually remote ends of the pair of arc-shaped insertion rods 302 are respectively inserted into the arc-shaped slots 204 provided at the ends of the pair of arc-shaped plates 202. Through the insertion action of the arc-shaped insertion rods 302 and the arc-shaped slots 204, and the elastic force of the elastic member 303, and when the bottom of the arc-shaped tube 301 is in contact with the top of the large-diameter section of the first connecting sleeve 102, the arc-shaped plate 202 can be limited, making it not easy to be pulled out from the arc-shaped through groove 103, so as to ensure that the first connecting sleeve 102 and the second connecting sleeve 201 can be firmly connected together.

[0036] Furthermore, a pair of moving grooves 304 communicating with the inside of the arc-shaped tube 301 are provided on the side of the arc-shaped tube 301 away from the first connecting sleeve 102. A moving handle 305 is slidably penetrated through each of the pair of moving grooves 304. The inner ends of the pair of moving handles 305 are respectively fixedly connected to the pair of arc-shaped insertion rods 302. By providing the moving handle 305, it is convenient to drive the arc-shaped insertion rod 302 to move through the moving handle 305, so as to facilitate pulling out the arc-shaped insertion rod 302 from the arc-shaped slot 204, and further facilitate removing the limit on the arc-shaped plate 202, which is convenient for disassembling the first connecting sleeve 102, and thus convenient for replacing the turntable body 101.

[0037] In summary, when in use, when the turntable body 101 needs to be replaced, it is not necessary to disassemble the second connecting sleeve 201. Only the first connecting sleeve 102 needs to be disassembled from the second connecting sleeve 201. The specific operation is as follows: First, simultaneously drive the pair of arc-shaped insertion rods 302 to retreat through the pair of moving handles 305. The elastic member 303 is compressed, and the arc-shaped insertion rods 302 are pulled out from the arc-shaped slots 204. After being pulled out, the fixing structure 300 is removed from the first connecting sleeve 102 and reserved for later use. Then, pull the first connecting sleeve 102 upward through the turntable body 101, so that the first connecting sleeve 102 is removed from the arc-shaped plate 202 and the connecting shaft, completing the disassembly. The overall operation is simple, without the need to rely on other tools, and the disassembly efficiency is high, which is convenient for replacing the turntable body 101.
