Description

Technical Field

[0001] This utility model relates to the field of installation structure technology, specifically to an air switch installation structure. Background Technology

[0002] An air switch, also known as an air circuit breaker, is a type of circuit breaker. It is a switch that automatically disconnects when the current in the circuit exceeds the rated current. Air switches are a very important electrical appliance in low-voltage power distribution networks and electric drive systems, integrating control and multiple protection functions. In addition to connecting and disconnecting circuits, it can also protect against short circuits, severe overloads, and undervoltage in circuits or electrical equipment, and can also be used for infrequent starting of motors.

[0003] Nowadays, household circuit breakers are generally installed inside walls, with a mounting slot cut into the wall. An installation box is placed inside the slot to hold the circuit breaker. A clip is typically used to secure the circuit breaker to the mounting box. While this method ensures stability, if the circuit breaker is damaged, disassembly requires prying the bottom of the clip with a screwdriver, which is inconvenient. A related technology places the circuit breaker against the inner wall of the installation box, positioning it inside a pressure plate. The pressure plate presses against the circuit breaker, and a support member supports the upper pressure plate, making the two pressure plates a single unit that presses against the circuit breaker. Then, releasing the clip allows it to be pushed out by a spring, blocking the outer wall of the pressure plate and thus securing the circuit breaker. This achieves convenient installation. However, because the position of the support member and the length of the pressure plate are fixed, when the circuit breaker size is different, the support member may obstruct the circuit breaker's start button, causing inconvenience. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an air switch installation structure that facilitates the disassembly of the air switch and does not obstruct the start button due to different air switch sizes, thus solving the problem of existing air switches being difficult to disassemble.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air switch mounting structure, comprising: a mounting box, wherein a mounting rail is fixedly connected inside; an air switch body is mounted on one side of the mounting rail; an assembly assembly is provided between the mounting rail and the air switch body; the assembly assembly comprises: a fixing seat, fixedly connected to the bottom of one side of the air switch body; a locking block is slidably connected inside the fixing seat, and springs are provided between the two sides of the locking block and the fixing seat; a positioning slider is slidably connected inside the side of the locking block; side sliders are fixedly connected to both sides of the positioning slider; a guide rod is slidably connected inside the side slider, and a spring is sleeved on the outside of the guide rod; a limit post is fixedly connected inside the fixing seat and on one side of the positioning slider; an unlocking ring is slidably connected to the outside of the limit post.

[0008] In some embodiments, the fixing base and the card block are provided with auxiliary components; the auxiliary components include: an auxiliary handle, which is fixedly connected to the bottom of the card block, and the length of the auxiliary handle is greater than that of the card block; the fixing base has an auxiliary groove inside.

[0009] In some embodiments, a limiting block is provided on one side of the card block, and when the bottom of the limiting block abuts against the top of the auxiliary groove, the positioning slider is exactly below the unlocking ring.

[0010] In some embodiments, a groove is formed on the outside of the limiting post and on one side of the fixing base, the width of the groove being equal to that of the positioning slider, and one side of the unlocking ring extending out of the groove.

[0011] In some embodiments, the springs on both sides of the block are compressed when the block is pulled down.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an air switch installation structure, which has the following advantages:

[0017] When the air switch body needs to be disassembled, simply pull the auxiliary handle down slowly to insert the positioning slider on one side of the locking block into the grooves on both sides of the fixing base. The top of the groove will limit the positioning slider, preventing the springs on both sides of the locking block from pushing the locking block up, thus keeping the positioning slider detached from the mounting rail, facilitating the disassembly of the air switch body. When the air switch body needs to be installed, simply adjust the positioning slider to the disassembly position, place the air switch body on the mounting rail, pull the auxiliary handle down all the way and then release it. The positioning slider will then push the unlocking ring upward under the action of the springs on both sides of the locking block. After reaching the top of the groove, the arc surface at the bottom of the unlocking ring will push the positioning slider out of the groove, allowing the positioning slider to continue moving upward and locking onto the mounting rail for easy use.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0028] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly.

[0030] When in use, the operator connects the air switch to the wire, then installs it inside the mounting box via the clip, and flips the switch upwards to supply power.

[0031] In related technologies, the air switch is placed against the inner wall of the mounting box, and the air switch is located inside the pressure plate, so that the pressure plate squeezes the air switch. A support member is used to support the pressure plate above, so that the two pressure plates are integrated to squeeze the air switch. Then, the locking block is released, and the locking block is pushed out by the spring, so that the locking block blocks the outer wall of the pressure plate, thereby squeezing and fixing the air switch, achieving the effect of convenient installation. However, since the position of the support member and the length of the pressure plate are fixed, when the size of the air switch is different, the support member may block the air switch start button, causing inconvenience in use.

[0032] To address some of the problems in related technologies, this application provides an air switch installation structure. When the air switch body 13 needs to be disassembled, simply pull down the auxiliary handle 31 slowly to insert the positioning slider 23 on one side of the locking block 22 into the grooves on both sides of the fixing base 21. The top of the groove can limit the positioning slider 23, preventing the springs on both sides of the locking block 22 from pushing the locking block 22 up, thereby keeping the positioning slider 23 detached from the mounting rail 12, facilitating the disassembly of the air switch body 13. When the air switch body 13 needs to be installed, simply adjust the positioning slider 23 to the disassembly state, place the air switch body 13 on the mounting rail 12, pull down the auxiliary handle 31 all the way down and then release it. The positioning slider 23 will then push the unlocking ring 27 upward under the action of the springs on both sides of the locking block 22. After reaching the top of the groove, the arc surface at the bottom of the unlocking ring 27 will push the positioning slider 23 to slide out of the groove, thereby allowing the positioning slider 23 to continue to move upward and lock onto the mounting rail 12 for easy use.

[0033] This application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Combination Figures 1-4 This application provides an air switch mounting structure, including: a mounting box 11, with a mounting rail 12 fixedly connected inside; an air switch body 13 mounted on one side of the mounting rail 12; an assembly assembly 2 disposed between the mounting rail 12 and the air switch body 13; the assembly assembly 2 includes: a fixing seat 21, fixedly connected to the bottom of one side of the air switch body 13; a locking block 22 slidably connected inside the fixing seat 21, and springs disposed between the two sides of the locking block 22 and the fixing seat 21; a positioning slider 23 slidably connected inside the side of the locking block 22; side sliders 24 fixedly connected to the two sides of the positioning slider 23; a guide rod 25 slidably connected inside the side slider 24, and a spring sleeved on the outside of the guide rod 25; a limit post 26 fixedly connected inside the fixing seat 21 and located on one side of the positioning slider 23; and an unlocking ring 27 slidably connected to the outside of the limit post 26.

[0035] In use, connect the air switch body 13 to the power cord, mount it on the mounting rail 12, and push the switch on the air switch body 13 upwards to turn on the power. After that, close the door of the mounting box 11 for normal use. When the air switch body 13 needs to be disassembled, slowly pull down the auxiliary handle 31 to move the locking block 22 downwards and compress the springs on both sides of the locking block 22. When the positioning slider 23 reaches the grooves on both sides of the fixing seat 21, it is pushed into the grooves by the springs. The top of the grooves limits the positioning slider 23, preventing the springs on both sides of the locking block 22 from pushing the locking block 22 upwards, thus keeping the positioning slider 23 detached from the mounting rail 12 for easy disassembly of the air switch body 13. When the air switch body 13 needs to be installed, first adjust the positioning slider 23 to the disassembled position, and then install the air switch body 13. After the gas switch body 13 is aligned with the mounting rail 12 and inserted, pull down the auxiliary handle 31 all the way and then release it. The positioning slider 23 will then move upward under the action of the springs on both sides of the locking block 22, thereby pushing the unlocking ring 27 upward. When the unlocking ring 27 reaches the top of the groove, the arc surface at the bottom of the unlocking ring 27 will press against one side of the positioning slider 23, thereby pushing the positioning slider 23 towards the inside of the locking block 22, and then causing the positioning slider 23 to slide out of the groove. When the locking block 22 continues to move upward and the positioning slider 23 disengages from the unlocking ring 27, since one side of the unlocking ring 27 extends out of the groove, the sliding positioning slider 23 continues to move upward under the action of the springs on both sides of the locking block 22. Since the gap between the top of the unlocking ring 27 and the top of the groove is small, the sliding positioning slider 23 does not have time to re-insert into the groove, and thus continues to move upward until it is locked on the mounting rail 12 for easy use.

[0036] In some embodiments, an auxiliary component 3 is provided on the fixing base 21 and the locking block 22; the auxiliary component 3 includes: an auxiliary handle 31, which is fixedly connected to the bottom of the locking block 22, and the length of the auxiliary handle 31 is greater than that of the locking block 22; an auxiliary groove 32 is provided inside the fixing base 21 to prevent the auxiliary handle 31 from moving into the interior of the fixing base 21 along with the sliding groove outside the locking block 22. The auxiliary groove 32 is used to limit the sliding of the locking block 22 and also serves as an indicator. When the locking block 22 cannot be pulled down any further, it can be determined that the positioning slider 23 has been pulled below the unlocking ring 27.

[0037] In some embodiments, a limiting block is provided on one side of the card block 22. When the bottom of the limiting block abuts against the top of the auxiliary groove 32, the positioning slider 23 is located just below the unlocking ring 27, which facilitates the subsequent unlocking by pushing the upward-moving positioning slider 23 through the unlocking ring 27.

[0038] In some embodiments, a groove is formed on the outside of the limiting post 26 and on one side of the fixing base 21. The width of the groove is equal to that of the positioning slider 23, and one side of the unlocking ring 27 extends out of the groove, so that the positioning slider 23 can be inserted into the groove, thereby limiting the positioning slider 23 by the top of the groove.

[0039] In some embodiments, the springs on both sides of the locking block 22 are compressed when the locking block 22 is pulled down, so that the locking block 22 can remain engaged with the mounting rail when it is not pulled down, thereby enhancing the stability of the installation.

[0040] In some embodiments, one end of the positioning slider 23 extends to the outside of the block 22, and the extended portion of the positioning slider 23 is provided with a slope, so that when the block 22 is pulled down toward the unlocking ring 27, the slope on one side of the positioning slider 23 is pressed, thereby causing the positioning slider 23 to move toward the inside of the block 22, so that the positioning slider 23 passes the position of the unlocking ring 27.

[0041] In some embodiments, the positioning slider 23, the limiting post 26, and the unlocking ring 27 are a group, and the locking block 22 and the fixing seat 21 are provided with two groups inside, which are symmetrically arranged to enhance the stability of positioning.

[0042] In some embodiments, the top and bottom of the unlocking ring 27 are both curved discs, which facilitates the movement of the positioning slider 23.
