The fixing block also compresses the second spring. When the fixing block aligns with the circular groove on the surface of the static conductive rod body, the rebound of the second spring fixes the static conductive rod body in place.

Description

Technical Field

[0001] This utility model relates to the field of static conductive rod installation technology, and in particular to a high-precision vacuum switch static conductive rod installation bracket. Background Technology

[0002] A vacuum switch is a high-voltage electrical device that uses a vacuum environment as the arc-extinguishing medium. Its core component is the vacuum interrupter chamber, which contains a contact system composed of moving and stationary conductive rods. The stationary conductive rod, as a fixed contact, directly affects the switch's contact performance, conductivity stability, and arc-extinguishing effect through its installation accuracy.

[0003] Existing static conductor rod mounting brackets typically employ rigid fixing structures, such as directly locking the static conductor rod to the arc-extinguishing chamber flange with bolts. However, such structures have the following drawbacks: the coaxiality of the static and moving conductor rods relies on manual adjustment, making it difficult to guarantee the required deviation during long-term operation. This can easily lead to uneven wear of the contacts or increased contact resistance. Furthermore, the mechanical vibration during switch opening and closing can easily loosen the bracket bolts, causing a drop in contact pressure and even arc reignition. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of insufficient installation accuracy and poor seismic performance in existing technologies by providing a high-precision vacuum switch static conductive rod mounting bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision vacuum switch static conductive rod mounting bracket, comprising a ceramic tube, a static conductive rod body provided on the inner wall of the ceramic tube, an annular frame fixedly connected to the inner wall of the ceramic tube, a crossbar fixedly connected to the outer surface of the annular frame, a column sleeved on the inner wall of the crossbar, a collar fixedly connected to one end of the column, a fixing block sleeved on the inner wall of the collar, a sliding rod fixedly connected to one end of the fixing block, a second spring sleeved on the outer surface of the sliding rod, a flange provided on one side of the annular frame, and bolts sleeved on the inner wall of the flange.

[0006] In a preferred embodiment, one end of the column is provided with a slider, a connecting rod is fixedly connected to the outer surface of the slider, a locking block is fixedly connected to one end of the connecting rod, a groove is provided on the inner wall of the column, a fixing rod is fixedly connected to the inner wall of the groove, and a first spring is sleeved on the outer surface of the fixing rod.

[0007] In a preferred embodiment, one end of the first spring is fixedly connected to the inner wall of the groove, the other end of the first spring is fixedly connected to one side of the locking block, and the inner wall of the locking block is slidably connected to the outer surface of the fixing rod.

[0008] In a preferred embodiment, the outer surface of the crossbar is provided with a locking hole, and the inner wall of the locking hole is engaged with the outer surface of the locking block.

[0009] In a preferred embodiment, a circular groove is formed on the outer surface of the static conductive rod body, and the outer surface of the fixing block is engaged with the inner wall of the circular groove.

[0010] In a preferred embodiment, one end of the second spring is fixedly connected to one side of the inner wall of the collar, and the other end of the second spring is fixedly connected to one side of the fixing block.

[0011] In a preferred embodiment, the outer surface of the slide rod is slidably connected to the inner wall of the collar, and the outer surface of the fixing block is slidably connected to the inner wall of the collar.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention uses a ceramic tube to seal the conductive rod, creating a vacuum area. The static conductive rod body ensures normal conductivity, while the ring frame provides an installation environment for other components and prevents the support from falling off. A crossbar slides between the crossbar and the column, allowing the column to move freely. A collar prevents the static conductive rod body from tilting. During installation, the static conductive rod body is first passed through the collar and moves inside it. This movement compresses a fixing block, causing it to move a sliding rod into the collar. The fixing block also compresses a second spring. Once the fixing block aligns with the circular groove on the surface of the static conductive rod body, the spring's rebound secures the rod body. Finally, a flange is connected to the static conductive rod body, and bolts are used to fix the flange to the ring frame, ensuring the static conductive rod body does not fall off.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a high-precision vacuum switch static conductive rod mounting bracket, including a ceramic tube 1, a static conductive rod body 2 provided on the inner wall of the ceramic tube 1, an annular frame 4 fixedly connected to the inner wall of the ceramic tube 1, a crossbar 5 fixedly connected to the outer surface of the annular frame 4, a column 6 sleeved on the inner wall of the crossbar 5, a collar 13 fixedly connected to one end of the column 6, a fixing block 14 sleeved on the inner wall of the collar 13, a sliding rod 16 fixedly connected to one end of the fixing block 14, a second spring 15 sleeved on the outer surface of the sliding rod 16, a flange 3 provided on one side of the annular frame 4, and a bolt 7 sleeved on the inner wall of the flange 3.

[0022] In this embodiment, the conductive rod is sealed by the ceramic tube 1 to form a vacuum area. The static conductive rod body 2 ensures normal conductivity. The ring frame 4 provides an installation environment for other components and ensures that the support will not fall off. The crossbar 5 is slidably connected to the column 6, allowing the column 6 to move normally. The collar 13 is used to ensure that the static conductive rod body 2 does not tilt. When installing the static conductive rod body 2, it is first passed through the collar 13 and moves inside the collar 13. When the static conductive rod body 2 moves, it will squeeze the fixing block 14, causing the fixing block 14 to drive the sliding rod 16 to move into the collar 13. The fixing block 14 will also compress the second spring 15. When the fixing block 14 is aligned with the circular groove on the surface of the static conductive rod body 2, the static conductive rod body 2 is fixed by the rebound of the second spring 15. Then, the flange 3 is connected to the static conductive rod body 2, and the flange 3 is fixed to the ring frame 4 by bolts 7, thus ensuring that the static conductive rod body 2 will not fall off. Example

[0023] like Figures 1-4 As shown, a slider 8 is provided at one end of the column 6, a connecting rod 9 is fixedly connected to the outer surface of the slider 8, a locking block 10 is fixedly connected to one end of the connecting rod 9, a groove is provided on the inner wall of the column 6, a fixing rod 11 is fixedly connected to the inner wall of the groove, a first spring 12 is sleeved on the outer surface of the fixing rod 11, one end of the first spring 12 is fixedly connected to the inner wall of the groove, and the other end of the first spring 12 is fixedly connected to one side of the locking block 10, and the inner wall of the locking block 10 is slidably connected to the outer surface of the fixing rod 11.

[0024] In this embodiment, when the static conductive rod body 2 needs to be installed, the operator first moves the connecting rod 9 by pressing the slider 8. As the connecting rod 9 moves, the locking block 10 moves, causing the locking block 10 to separate from the locking hole and compressing the first spring 12. Then, the column 6 rises above the ceramic tube 1, making it easier for the operator to connect the static conductive rod body 2 to the collar 13. After the static conductive rod body 2 and the collar 13 are fixed, the static conductive rod body 2 is retracted into the ceramic tube 1 by sliding the column 6. Then, the rebound of the first spring 12 causes the locking block 10 to reset along the fixing rod 11, thereby locking the locking block 10 into the locking hole, thus completing the fixation of the column 6 and ensuring that the column 6 will not shake, thereby achieving the purpose of preventing the static conductive rod 2 from shaking.

[0025] Working principle:

[0026] like Figures 1-4As shown, in this utility model, when the worker needs to install the static conductive rod body 2 using the mounting bracket, the worker first moves the connecting rod 9 by pressing the slider 8. Simultaneously, the moving connecting rod 9 moves the locking block 10, causing it to separate from the locking hole and compressing the first spring 12. Then, the column 6 rises above the ceramic tube 1, facilitating the worker to connect the static conductive rod body 2 to the collar 13. The static conductive rod body 2 passes through the collar 13 and moves inside it. During this movement, the static conductive rod body 2 presses against the fixing block 14, causing the fixing block 14 to move the sliding rod 16 into the collar 13. The fixing block 14 also presses against the second... When the spring 15 is compressed, and the fixing block 14 is aligned with the circular groove on the surface of the static conductive rod body 2, the static conductive rod body 2 is fixed by the rebound of the second spring 15. Then, the flange 3 is connected to the static conductive rod body 2, and the flange 3 is fixed to the ring frame 4 by the bolt 7, so as to ensure that the static conductive rod body 2 will not fall off. After the static conductive rod body 2 is fixed to the collar 13, the static conductive rod body 2 is retracted into the ceramic tube 1 by the sliding column 6. Then, the first spring 12 drives the locking block 10 to reset along the fixing rod 11, so that the locking block 10 engages with the locking hole, thereby completing the fixation of the column 6 and ensuring that the column 6 will not shake.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
