In the figure, the device comprises a mounting column 1, a mounting column 2, a mounting body 3, a spring 4, a pressure ball 5, a mounting main body 6, an inclined plane structure 7, an arc-shaped bulge 8, an inner spacer 9 and a rotary sleeve.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
A quick release type high voltage dc contactor as shown in fig. 1 to fig. 3 is the preferred embodiment of the present invention, which is installed on the installation body 5, and includes an installation housing 2 and an installation post 1 fixed on the lower end surface of the installation housing 2. The surface of the mounting main body 5 is provided with a mounting cavity for the mounting column 1 to extend into, and the mounting cavity is internally and rotatably connected with a rotary sleeve 9. The rotating sleeve 9 is internally provided with a spring 3 and two pressing balls 4. The surface of the mounting main body 5 is provided with a mounting hole for the mounting column 1 to extend into and also provided with an annular groove for the top of the rotary sleeve 9 to protrude, and the surface of the mounting main body 5 is a sealing surface corresponding to other positions except the mounting hole and the annular groove, namely the spring 3 and the pressure ball 4 are limited in the mounting cavity.
The circumference inner wall of swivel mount sleeve 9 be the inclined plane structure 6 that the outer is big-end-up, the bottom surface of swivel mount sleeve 9 arc arch 7 that has two symmetrical designs, and the arc centre of a circle of arc arch 7 is concentric with swivel mount sleeve 9, arc arch 7 be middle high, along the structure that arc both sides direction gradually reduces for swivel mount sleeve 9 bottom surface, the face of being connected along the arc direction of arc arch 7 and swivel mount sleeve 9's bottom surface is transition inclined plane, is equipped with pressure ball 4 between two arc arch 7 both sides respectively, 4 tops of pressure ball and installation main part 5 between elastic connection have spring 3, erection column 1 circumference outer wall compress tightly with the contact of pressure ball 4 when pegging graft into the installation cavity. The elasticity of the spring 3 needs to be designed according to the pressure of the inclined surface structure 6 on the pressure ball 4, and the pressure ball 4 is pressed on the mounting column 1 to ensure that the mounting column 1 does not displace. Meanwhile, the force which can drive the pressing ball 4 to upwards press the spring 3 by rotating the rotary sleeve 9 is also considered, and the force can be implemented by an installer.
During the installation, erection column 1 corresponds the mounting hole position and inserts to end, pushes away the in-process, and erection column 1 can extrude pressure ball 4 gradually, makes pressure ball 4 and the contact of inclined plane structure 6 and locking, and when 3 elastic forces of spring acted on simultaneously, pressure ball 4 was fixed a position by the crimping, and pressure ball 4 compresses tightly on erection column 1 surface, realizes the firm fixed after 1 grafting of erection column. When the contactor is dismantled to needs, then rotate swivel sleeve 9, the arc arch 7 of swivel sleeve 9 bottom surface rotates and drives and press ball 4 upwards to extrude spring 3, presses ball 4 simultaneously under the effect of swivel sleeve 9's inclined plane structure 6, loosens from erection column 1 circumference, removes the locking to erection column 1, and erection column 1 can be extracted smoothly, realizes demolising of contactor, and the installation of contactor is dismantled swiftly conveniently.
In actual design, in order to avoid the installation column 1 to be pulled out, the pressing ball 4 cannot be stably controlled between the arc-shaped protrusions 7 of the rotary sleeve 9 by the spring 3 alone, the inner spacer 8 can be designed between the inner sides of the arc-shaped protrusions 7 correspondingly, the height of the inner spacer 8 needs to be reasonably set, the pressing ball 4 is guaranteed to be lower than the compression locking position of the installation column 1, and interference can not be caused to the dismounting locking of the installation column 1. So, when not installing the contactor, press ball 4 to be compressed tightly by spring 3, the probability of taking place the motion is very little, and simultaneously through spacing of interior spacer 8, can only take place little displacement between inclined plane structure 6, the arc arch 7 of interior spacer 8, swivel mount 9 again, press ball 4 can not drop and cause the influence.
The quick-release high-voltage direct-current contactor is reasonable in structural design, cooperation among the pressure ball 4, the spring 3 and the rotary sleeve 9 is ingeniously utilized, quick disassembly and assembly between the contactor mounting column 1 and the mounting main body 5 are achieved, and the mounting process is more convenient and rapid.
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.
