Description

Technical Field

[0001] This utility model relates to the field of SF6 density controller technology, and in particular to an SF6 density controller with axial and radial dual mounting methods. Background Technology

[0002] An SF6 density controller is a device used to monitor the SF6 gas density in the gas chamber of SF6 high-voltage electrical equipment. Its main function is to issue a gas replenishment or lockout signal when a gas leak occurs in the gas chamber, so as to ensure the safe operation of the equipment.

[0003] The existing patent document with publication number CN222599443U discloses a micro-switch type SF6 density controller. Through the setting of a locking groove and locking component, it can realize the quick disassembly and assembly function between the interface and the mounting groove. Through the setting of a first arc-shaped guide groove, by rotating the SF6 density controller body at a certain angle, the locking head can move upward along the first arc-shaped guide groove, thereby moving the lower end of the interface downward, so that the first sealing ring is tightly pressed into the sealing step groove, ensuring the sealing of the connection between the mounting groove and the interface.

[0004] Although the aforementioned micro-switch type SF6 density controller can solve the corresponding technical problems, its locking component mainly relies on spring pressure to press the locking head into the locking groove. However, fixing the interface with a spring is prone to shaking due to the spring force, resulting in instability of the locking head, which in turn reduces the connection stability between the structure and the mounting groove.

[0005] To address this, an SF6 density controller with dual axial and radial mounting methods is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an SF6 density controller with axial and radial dual mounting methods to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] An SF6 density controller with axial and radial dual mounting methods includes:

[0009] The SF6 density controller body has a connector fixedly connected to its bottom. A connecting component is connected to the connector. The connecting component can be installed on a connecting pipe by means of a nut. A limiting component is provided on the connecting component.

[0010] The connecting assembly includes a hollow bolt connected to the bottom end of the connector, the hollow bolt being threadedly connected to a nut, the hollow bolt being provided with a locking element that mates with the connector, and the limiting assembly being provided on the hollow bolt and used to limit and fix the locking element.

[0011] The limiting component includes a limiting seat fixedly connected to the handle of the locking member. The inner cavity of the limiting seat is movably fitted with a pin. Both ends of the pin are fitted with supports. The supports are located on the locking member. The pin can move up and down within the supports to disengage from or engage with the limiting seat.

[0012] As a preferred technical solution, the inner cavity of the limiting seat has an arc-shaped structure, and the pin has a U-shaped structure.

[0013] As a preferred technical solution, the support is provided with a sliding hole for inserting the end of the pin, and the inner wall of the sliding hole is slidably connected to the surface of the pin.

[0014] As a preferred technical solution, a magnet is fixedly connected to the bottom of the inner cavity of the sliding hole, and an iron sheet is fixedly connected to the end of the pin. The iron sheet is magnetically attracted to the top of the corresponding magnet.

[0015] As a preferred technical solution, the limiting seat has an inclined surface on one side facing the central axis of the hollow bolt, and the horizontal line on the side of the inclined surface near the center of the limiting seat is higher than the horizontal line on the other side.

[0016] As a preferred technical solution, the surface of the hollow bolt is provided with a groove, and the handle, limit seat, pin and support of the locking member are all located in the groove, and the bottom of the support is fixedly connected to the bottom of the inner cavity of the groove.

[0017] As a preferred technical solution, the distance between the top of the groove cavity and the pin is less than the movable distance of the pin end in the sliding hole, and the distance between the top of the groove cavity and the pin is greater than the height of the limiting seat cavity.

[0018] This utility model has at least the following beneficial effects:

[0019] This application, by adding a limiting component to the connecting assembly, ensures the quick assembly and disassembly function between the connector and the connecting assembly. By locking the limiting seat into the pin, it works with the support to further secure the locking component, limiting the locking component from swaying freely on the hollow bolt. This prevents the spring from gradually losing its elasticity after prolonged use, thus avoiding the phenomenon of the locking component becoming loose. This effectively improves the connection stability between the connector and the connecting assembly. At the same time, when the locking component is pulled, the limiting seat can also act as an anti-slip component, increasing the friction between the hand and the handle of the locking component, thus providing an anti-slip effect.

[0027] 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.

[0028] Please see Figures 1-6This utility model provides an SF6 density controller with axial and radial dual installation methods, including an SF6 density controller body 100, a connector 200, a connecting component 300, and a limiting component 400, which are fixedly connected to the bottom of the SF6 density controller body 100. The connector 200 and the connecting component 300 are connected and cooperate to achieve quick assembly and disassembly. The connecting component 300 can be installed on the connecting pipe 1 by a nut 2. The limiting component 400 is provided on the connecting component 300. The connecting component 300 includes a hollow bolt 310 connected to the bottom end of the connector 200. 10 is threadedly connected to nut 2. Hollow bolt 310 is provided with locking member 320 for use with connector 200. Limiting component 400 is provided on hollow bolt 310 and is used to limit and fix locking member 320. Limiting component 400 includes limiting seat 410 fixedly connected to handle of locking member 320. The inner cavity of limiting seat 410 is movably fitted with pin 420. Both ends of pin 420 are fitted with support 430. Support 430 is provided on locking member 320. Pin 420 can move up and down in support 430 to disengage or engage in limiting seat 410.

[0029] It should be further noted that the working principles of the SF6 density controller body 100, connector 200 and connecting component 300 in this embodiment are the same as those of the SF6 density controller body, interface and connector in a micro-switch type SF6 density controller disclosed in Chinese Patent No. CN222599443U. It is prior art, so it will not be described in detail in this technical solution.

[0030] The inner cavity of the limiting seat 410 has an arc-shaped structure, and the pin 420 has a U-shaped structure.

[0031] The support 430 has a sliding hole 440 for inserting the end of the pin 420. The inner wall of the sliding hole 440 is slidably connected to the surface of the pin 420. The sliding hole 440 can guide the pin 420, so that the pin 420 can move up and down stably and avoid shaking or deviation, so as to ensure that the pin 420 can always be aligned with the inner cavity of the limit seat 410.

[0032] A magnet 450 is fixedly connected to the bottom of the inner cavity of the sliding hole 440, and an iron piece 460 is fixedly connected to the end of the pin 420. The iron piece 460 is magnetically attracted to the top of the corresponding magnet 450. Through the cooperation of the magnet 450 and the iron piece 460, when the pin 420 is inserted into the inner cavity of the limiting seat 410, the iron piece 460 and the magnet 450 are attracted together, so that the pin 420 can be stably locked into the limiting seat 410, preventing accidental disengagement.

[0033] The limiting seat 410 has an inclined surface 411 on one side facing the central axis of the hollow bolt 310. The horizontal line of the inclined surface 411 near the center of the limiting seat 410 is higher than the horizontal line of the other side. The inclined surface 411 allows the locking member 320 to be reset and engaged in the locking groove on the connector 200. When the locking member 320 is engaged in the locking groove, the inclined surface 411 on the limiting seat 410 will first contact the pin 420. Under the spring force of the locking member 320, the inclined surface 411 applies pressure to the pin 420, causing the pin to engage. Pin 420 can move upward on its own to avoid the limiting seat 410 until the locking member 320 is engaged in the locking groove on the connector 200. Then, pin 420 is unrestrained and pin 420 can move downward on its own by its own weight and the cooperation of magnet 450 and iron plate 460 until pin 420 is engaged in the limiting seat 410. Thus, when the locking member 320 is reset, there is no need to operate pin 420, thereby reducing the disassembly and assembly steps of connector 200 and connecting component 300.

[0034] The hollow bolt 310 has a groove 500 on its surface. The handle, limit seat 410, pin 420 and support 430 of the locking member 320 are all located in the groove 500. The bottom of the support 430 is fixedly connected to the bottom of the inner cavity of the groove 500. The handle of the locking member 320 and the limit component 400 can be hidden through the groove 500 to avoid excessive structural protrusion. This not only improves the connection stability between the connector 200 and the connecting component 300, but also improves the overall aesthetics.

[0035] The distance between the top of the inner cavity of the groove 500 and the pin 420 is less than the movable distance of the end of the pin 420 within the sliding hole 440. The distance between the top of the inner cavity of the groove 500 and the pin 420 is greater than the height of the inner cavity of the limiting seat 410. This distance difference ensures that after the pin 420 moves out of the limiting seat 410, the end of the pin 420 remains within the sliding hole 440, thus preventing the pin 420 from moving excessively and slipping out of the sliding hole 440.

[0036] The working principle of this utility model is as follows: By moving the pin 420 upward, the pin 420 drives the iron piece 460 to slide within the sliding hole 440, causing the iron piece 460 to separate from the magnet 450. This continues until the pin 420 moves to its maximum extent, disengaging from the inner cavity of the limiting seat 410. At this point, the limiting seat 410 can be used to pull the locking member 320 outward and release the pin 420 until the locking member 320 moves to its maximum extent. Then, the bottom end of the connector 200 can be quickly inserted into the hollow bolt 310 for connection. After connection, the locking member 320 is released, and it resets due to its spring force, thus locking... The fixed part 320 drives the limiting seat 410 and the inclined surface 411 to move towards the inner cavity of the groove 500. The limiting seat 410 applies pressure to the pin 420 through the inclined surface 411, causing the pin 420 to move upward on its own until the locking head of the locking part 320 is engaged in the locking groove of the connector 200. The pin 420 is then unrestrained and can move downward on its own until it is engaged in the limiting seat 410, thus completing the limiting and fixing of the locking part 320. Through the cooperation of the nut 2 and the hollow bolt 310, both axial and radial installation methods of the SF6 density controller body 100 can be realized, which can solve the problem of insufficient installation space on site.

[0037] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model 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 this utility model, the scope of which is defined by the appended claims and their equivalents.
