The utility model provides a technical scheme that its technical problem adopted is:
a connecting structure of an electric operating mechanism of a plastic shell switch,
including the transfer line, the one end of transfer line forms the installation department, the installation department is provided with joint ball bearing, joint ball bearing includes ball seat and universal ball, form the handle hole that is used for moulded the shell switch handle tip to wear out in the universal ball.
Further, the transmission rod mounting part is provided with a mounting hole which is a through hole, the joint ball bearing is arranged in the mounting hole, the upper side and the lower side of the mounting part are respectively and fixedly provided with a press mounting ring, the ball seat is pressed between the two press mounting rings, and the universal ball is arranged in the annular hole of the press mounting ring.
Further, the transmission rod mounting portion is provided with a mounting hole, the mounting hole is a step hole, the joint ball bearing is arranged in the mounting hole, the mounting portion is fixedly provided with a press mounting ring, and the ball seat is pressed in the mounting hole by the press mounting ring.
The utility model has the advantages that: the joint ball bearing is adopted, the angle can be automatically adjusted according to the action of the plastic shell switch handle, so that the stress of the plastic shell switch handle is balanced, the plastic shell switch handle is more reliable and flexible in action, and the service life of the plastic shell switch handle is prolonged.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
FIG. 1 is a schematic view of a first type of transmission rod;
FIG. 2 is a schematic view of a second type of transmission rod;
FIG. 3 is a schematic view showing the connection relationship between the motor, the output shaft and the transmission rod according to the present invention;
fig. 4 is a schematic view of the usage state of the switch handle with plastic shell in the utility model.
In the figure, 1, output shaft; 2. a motor; 3. a transmission rod; 31. mounting holes, 4, press mounting rings; 5. A joint ball bearing; 51. a ball seat; 52. a universal ball; 521. a handle aperture; 6. a connecting member.
Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the connecting structure of the plastic casing switch electric operating mechanism comprises a transmission rod 3, wherein an installation part is formed at one end of the transmission rod 3, a joint ball bearing 5 is arranged on the installation part, the joint ball bearing 5 comprises a ball seat 51 and a universal ball 52, and a handle hole 521 for penetrating out of the end part of a plastic casing switch handle is formed in the universal ball 52.
The first connection mode between the joint ball bearing 5 and the transmission rod 3 is shown in fig. 1, a mounting hole 31 is formed in a mounting part of the transmission rod 3, the mounting hole 31 is a through hole, the joint ball bearing 5 is arranged in the mounting hole 31, press mounting rings 4 are fixedly arranged on the upper side and the lower side of the mounting part respectively, the ball seat 51 is pressed between the two press mounting rings 4, and the universal ball 52 is located in a ring hole of the press mounting ring 4. The two press-fitting rings 4 can be fixed by using a connecting piece 6, such as rivet or bolt fastening, so as to fixedly connect the upper and lower press-fitting rings 4.
The second connection mode between the joint ball bearing 5 and the transmission rod 3 is as shown in fig. 2, a mounting hole 31 is formed in a mounting part of the transmission rod 3, the mounting hole 31 is a step hole, the joint ball bearing 5 is arranged in the mounting hole 31, a press mounting ring 4 is fixedly arranged on the mounting part, the ball seat 51 is pressed in the mounting hole 31 by the press mounting ring 4, and the press mounting ring 4 can be fixed on the transmission rod 3 through riveting or a bolt.
The mounting ring can also be connected to the drive rod 3 in other ways, for example by welding.
The joint ball bearing 5 belongs to common parts in the mechanical field, and is not described herein.
As shown in fig. 3 and 4, the utility model discloses a connection structure sets up in electric operating mechanism, and the other end of transfer line 3 is connected with electric operating mechanism's output shaft 1, and output shaft 1 drives transfer line 3 motion, and output shaft 1 is driven by motor 2 through gear drive mechanism, because present transfer line 3 relies on joint ball bearing 5 to be connected with the handle of moulding the shell switch, consequently, universal ball 52 is according to the action automatically regulated angle who moulds the shell switch handle for mould shell switch handle atress is balanced, difficult fracture.
The specific implementation process comprises the following steps:
when the breaker needs to realize the opening or closing function, the motor 2 drives the output shaft 1 to rotate, the output shaft 1 drives the transmission rod 3 to move, and then the molded case switch handle is driven to move, and when the molded case switch handle moves, the universal ball 52 can automatically adjust the angle according to the action of the molded case switch handle, so that the stress of the molded case switch handle is more balanced, and the service life of the molded case switch handle is prolonged.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
