Description

Technical Field

[0001] This utility model relates to the field of vacuum interrupter technology, specifically a shielding cylinder spinning and fixing clamp. Background Technology

[0002] In fields such as electronic communications, nuclear physics research, and medical equipment, shielding cylinders are key components primarily used to block electromagnetic interference, radioactive material leakage, or high-energy particle radiation, ensuring the normal operation of equipment and the safety of personnel. With the development of industry technology, higher requirements are being placed on the installation accuracy, fixation stability, and environmental adaptability of shielding cylinders. Currently, the main methods for fixing shielding cylinders include bolt fastening, snap-on fixing, and adhesive bonding. While bolt fastening can provide greater clamping force, it suffers from problems such as time-consuming installation and disassembly, potential damage to the shielding cylinder surface, and easy loosening of bolts due to vibration after long-term use. Adhesive bonding can achieve seamless fixing, but disassembly is difficult, and the fixing effect will decrease after the adhesive ages. In addition, some adhesives may release harmful substances, making them unsuitable for medical or precision instrument scenarios. Therefore, it is necessary to propose a shielding cylinder spinning fixing clamp. Utility Model Content

[0003] The purpose of this utility model is to provide a shielding cylinder spinning and fixing clamp to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shielding cylinder spinning and fixing clamp, comprising a ceramic shell and a push handle, wherein a shielding cylinder is slidably connected to the inner wall of the ceramic shell; The inner wall of the ceramic shell has a through groove, and a ring block is slidably connected to the inner wall of the groove. The ring block is fixedly connected to the shielding cylinder. An arc-shaped metal sheet is fixedly connected to the outer wall of one end of the shielding cylinder. One end of the push handle extends into the ceramic shell and is fixedly connected to a pressing block.

[0005] Preferably, a flexible gasket is fixedly connected to the outer wall of one end of the arc-shaped metal sheet, and the flexible gasket abuts against the ceramic shell.

[0006] Preferably, each of the arc-shaped metal sheets has an arc-shaped top block fixedly connected to its inner wall, and the arc-shaped top block abuts against the extrusion block.

[0007] Preferably, both the groove and the ring block are arranged in a circular shape.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the shielding cylinder is inserted into the ceramic shell, the ring block is moved to the bottom of the ceramic shell, the push plate is used to move the extrusion block into the ceramic shell, the extrusion block is rotated, the extrusion block pushes the arc-shaped metal sheet and the arc-shaped top block to rotate outward, the arc-shaped metal sheet drives the flexible pad to abut against the ceramic shell, the arc-shaped metal sheet and the arc-shaped top block are moved inward during disassembly, and the installation only requires pushing the push handle and rotating to complete the fixation, without the need for additional tools, reducing the operation threshold and improving the disassembly and assembly efficiency.

[0011] Please see Figure 1-4 This utility model provides a technical solution: Example 1: A shielding cylinder spinning and fixing clamp includes a ceramic shell 1 and a push handle 2, and a shielding cylinder 3 is slidably connected to the inner wall of the ceramic shell 1; A groove is provided through the inner wall of the ceramic shell 1. A ring block 4 is slidably connected to the inner wall of the groove. The ring block 4 is fixedly connected to the shielding cylinder 3. An arc-shaped metal sheet 5 is fixedly connected to the outer wall of one end of the shielding cylinder 3. One end of the push handle 2 extends into the ceramic shell 1 and is fixedly connected to a pressing block 6.

[0012] In use, insert the shielding cylinder 3 into the ceramic shell 1. The ring block 4 slides in the groove until it moves to the bottom of the groove. Use the push handle 2 to move the pressing block 6 into the ceramic shell 1. The pressing block 6 abuts against the shielding cylinder 3. Use the push handle 2 to drive the pressing block 6 to rotate. The pressing block 6 pushes the arc-shaped top block 8 and the arc-shaped metal piece 5 to rotate outward, so that the flexible pad 7 on the outside of the arc-shaped metal piece 5 abuts against the ceramic shell 1. The arc-shaped metal piece 5 and the flexible pad 7 fix the shielding cylinder 3 inside the ceramic shell 1. When disassembling, since the arc-shaped metal piece 5 and one end of the arc-shaped top block 8 are C-shaped, push the arc-shaped top block 8 inward to separate the arc-shaped metal piece 5 from the ceramic shell 1, and the shielding cylinder 3 can be taken out from the ceramic shell 1.

[0013] Example 2: This example differs from Example 1 in its technical solution; A flexible pad 7 is fixedly connected to the outer wall of one end of the arc-shaped metal sheet 5. The flexible pad 7 abuts against the ceramic shell 1, which facilitates the use of the flexible pad 7 to increase the friction of the arc-shaped metal sheet 5. Arc-shaped top blocks 8 are fixedly connected to the inner wall of the arc-shaped metal sheet 5. The arc-shaped top blocks 8 abut against the extrusion block 6, which facilitates the use of the extrusion block 6 to push the arc-shaped top blocks 8 and the arc-shaped metal sheet 5 to unfold outward. The groove and the ring block 4 are both arranged in a circular shape, which facilitates the sliding of the ring block 4 in the groove.

[0014] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
