Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to an assembly structure of an intelligent air switch circuit breaker. Background Art

[0002] Air switch, also known as air circuit breaker, is a type of circuit breaker. It is a switch that will automatically disconnect as long as the current in the circuit exceeds the rated current. Air switch is a very important electrical appliance in low-voltage distribution network and electric traction system. It integrates control and multiple protection functions. In addition to contacting and disconnecting circuits, it can also protect circuits or electrical equipment from short circuits, severe overloads and undervoltages. It can also be used to start motors infrequently.

[0003] The utility model patent with announcement number CN 220382019 U proposes an assembly structure of an air-break circuit breaker, comprising an air-break circuit breaker body, a connection block fixedly connected to the surface of the air-break circuit breaker body, a through hole provided on the surface of the connection block, a first limiting groove provided on the inner wall of the through hole, a U-shaped fixing block inserted into the interior of the through hole, and a first limiting block fixedly connected to the surface of the U-shaped fixing block. The assembly structure of the air-break circuit breaker improves the overall assembly stability through the arrangement of the U-shaped fixing block and the first limiting block. When assembly is required, the connection block connected to the air-break circuit breaker body is clamped on the connecting plate, and then the U-shaped fixing block is pinched to shrink the second spring, and then the U-shaped fixing block is inserted into the slot provided at the bottom of the connecting plate through the through hole provided in the connection block, and the first limiting block enters the second limiting groove to fix the air-break circuit breaker body, thereby improving the overall assembly stability.

[0004] In the actual operation process of the above case, the operator is still required to adjust the assembly structure one by one during assembly, including clamping the connecting block on the connecting plate, pinching the U-shaped fixing block, inserting the U-shaped fixing block into the slot, etc. These steps require the operator to perform delicate operations and arrangements, which increases the complexity and time cost of the operation. Therefore, the utility model provides an assembly structure of an intelligent air switch circuit breaker to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an assembly structure of an intelligent air switch circuit breaker, which can solve the above problems by setting an assembly mechanism.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0010] Optionally, the assembling mechanism comprises assembling holes and assembling protrusions opened on both sides of the circuit breaker, and the assembling holes and the assembling protrusions have the same shape and are symmetrically distributed on both sides of each circuit breaker.

[0011] Optionally, an assembling sleeve is fixedly connected to one side of the top of each circuit breaker, and an assembling block is rotatably connected to the other side of the top of each circuit breaker, and the interior of the assembling sleeve is adapted to the exterior of the assembling block.

[0012] Optionally, a deformation cavity is provided inside the assembling block, a weakening groove is provided on the outer wall of the deformation cavity, and a No. 1 buffer cavity is provided in the inner wall of the assembling block.

[0013] Optionally, an assembling groove is provided inside one side of the assembling sleeve, a guiding arc surface is provided at the opening of the assembling groove, and a second buffer cavity is provided in the inner wall of the assembling sleeve.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] In the above scheme, by setting up the assembly structure, the air circuit breaker body and the leakage circuit breaker body can be pre-fixed by the assembly holes and the assembly protrusions during use, and the assembly of the two circuit breakers can be realized by plugging the assembly sleeve and the assembly block, without too much operation. This design not only reduces the tools and time required for installation, but also reduces the difficulty of operation, so that even non-professionals can easily complete the installation. At the same time, the design of the assembly structure also takes into account safety and stability, ensuring that after the assembly is completed, the two circuit breakers can be firmly connected together without loosening or falling off. In addition, the assembly structure also has certain versatility and scalability. Due to the use of standardized assembly holes and assembly protrusions, this structure can be applied to a variety of different models of circuit breaker bodies, thereby achieving more flexible combination and matching. At the same time, if more circuit breakers need to be added or expanded functions need to be added, only the corresponding assembly sleeves and assembly blocks need to be added, without large-scale changes to the entire system.

[0016] In the above scheme, by setting up the mounting mechanism, the circuit breaker can be easily connected or separated from the mounting plate through the design of the clamping groove and the clamping block in the mounting mechanism. This design not only improves the efficiency of installation and removal, but also makes the circuit breaker more convenient when it needs maintenance or replacement. The use of the spring between the clamping block and the circuit breaker ensures a stable connection between the circuit breaker and the mounting plate. Even under the action of external force, the circuit breaker can maintain a close fit with the mounting plate to prevent safety hazards caused by looseness. BRIEF DESCRIPTION OF THE DRAWINGS

A slidable clamping block 7 is provided at the bottom of the circuit breaker, and the clamping block 7 is connected to the circuit breaker through a spring. When the circuit breaker is placed on the mounting plate 1, the clamping groove is aligned with the mounting plate 1, and the force of the spring pushes the clamping block 7 to move upward, so that the top of the clamping block 7 contacts the mounting plate 1, thereby fixing the circuit breaker.

[0032] In this embodiment, if Figures 1 to 5As shown, the assembling mechanism is used to improve the stability of the connection between the air circuit breaker body 2 and the leakage circuit breaker body 3. The assembling mechanism is connected to each circuit breaker. The assembling mechanism includes assembling holes 6 and assembling protrusions opened on both sides of the circuit breaker, and the assembling holes 6 and the assembling protrusions have the same shape and are symmetrically distributed on both sides of each circuit breaker. An assembling sleeve 4 is fixedly connected to one side of the top of each circuit breaker, and an assembling block 5 is rotatably connected to the other side of the top of each circuit breaker. The interior of the assembling sleeve 4 is adapted to the exterior of the assembling block 5.
