Description
Technical Field
The utility model relates to a low-voltage apparatus field, in particular to air switch's track structure.
Background
An air switch, also known as an air circuit breaker, is one type of circuit breaker. The switch can be automatically switched off as long as the current in the circuit exceeds the rated current. The air switch is an important electric appliance in a low-voltage distribution network and an electric power dragging system, and integrates control and multiple protection functions. Besides the contact and breaking of the circuit, the protection of short circuit, severe overload and undervoltage, etc. of the circuit or electrical equipment can be realized, and the protection device can also be used for starting the motor infrequently.
The existing air switch and the track fixed by the air switch are easy to loosen in the long-time use process, so that the air switch is separated from the track, and the normal power supply safety is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve above-mentioned problem through following technical scheme:
a track structure of an air switch, comprising: the air switch, the poking block, the mounting rail, the abutting rod and the spring are arranged on the mounting rail;
the poking block is connected with the front part of the air switch;
the top of the back of the air switch is provided with a first groove; an arc-shaped convex edge is arranged on one inner wall surface of the first groove;
the mounting rail is of a C-shaped structure, an arc-shaped groove is formed in the inner wall surface of the top of the mounting rail, and a clamping strip is arranged at the end part of the bottom of the mounting rail;
the arc-shaped convex edges and the arc-shaped grooves are matched with each other;
a second groove is formed in the bottom of the back of the air switch;
the second groove extends upwards to form two jacks;
the spring is fixed in the jack;
one end of the abutting rod is connected with the spring;
further, the tip of butt joint pole is globular, and the card strip is provided with the chamfer structure, is favorable to the butt joint pole to pass through the card strip.
The utility model discloses beneficial effect as follows:
the utility model discloses an air switch and mounting rail's structure can make air switch firmly together fixed with the mounting rail, and it is also comparatively convenient to install and dismantle air switch simultaneously.

Detailed Description
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are easily implemented by those having ordinary skill in the art to which the present invention pertains. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In addition, for the purpose of more clearly describing the present invention, parts not connected with the present invention will be omitted from the drawings.
A track structure of an air switch, comprising: the air switch comprises an air switch 1, a toggle block 2, a mounting rail 3, a butting rod 4 and a spring 5;
as shown in fig. 1, the dial block 2 is connected with the front part of the air switch 1;
as shown in fig. 2, a first groove 11 is arranged at the top of the back of the air switch 1; an arc-shaped rib 111 is arranged on one inner wall surface of the first groove 11;
as shown in fig. 4, the mounting rail 3 is a C-shaped structure, an arc-shaped groove 31 is formed on the inner wall surface of the top of the mounting rail, and a clamping strip 32 is arranged at the end of the bottom of the mounting rail;
the arc-shaped convex ribs 111 and the arc-shaped grooves 31 are matched with each other;
as shown in fig. 5, the bottom of the back of the air switch 1 is provided with a second groove 12;
two insertion holes 121 extend upwards from the second groove 12;
the spring 5 is fixed in the jack 121;
one end of the abutting rod 4 is connected with the spring 5;
when the air switch is installed, as shown in fig. 1, the arc-shaped groove 31 of the installation rail 3 is located above the clamping strip 32, then the air switch 1 is held and inclined, the arc-shaped convex rib 111 is combined with the arc-shaped groove 31, then the bottom of the air switch 1 is pushed, and the abutting rod 4 passes through the clamping strip 32 and is tightly abutted with the installation rail 3; the dismounting of the air switch 1 is the reverse of the mounting process.
Further, the end of the butt-joint rod 4 is spherical, and the clamping strip 32 is provided with a chamfer structure, so that the butt-joint rod 4 can pass through the clamping strip 32.
In the description of the present technical solution, it should be specifically noted that, unless explicitly stated or limited otherwise, the terms "mounted," "connected," and "connected" used herein should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
