Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1-3, an embodiment of the present utility model is provided: a miniature circuit breaker comprises a shell 1, wherein a mounting groove 12 is formed in the back surface of the shell 1; a buckle 11 is arranged above the mounting groove 12, and the lower part of the mounting groove 12 is in sliding fit with the locking piece 2; a spring 6 is arranged between the locking piece 2 and the shell 1, and a jack 5 is also arranged at the bottom of the locking piece.
Through the mode, the screw driver is connected with the jack 5, and the locking piece 2 is pried downwards, so that the locking piece 2 can be driven to slide downwards on the shell 1, and the spring 6 is compressed at the moment; thereby facilitating the separation of the mounting groove and the guide rail; conversely, when the buckle 11 on the mounting groove 12 is clamped above the guide rail, the screwdriver is pulled out, and at the moment, the spring 6 drives the locking piece 2 to slide towards the buckle 11, so that the shell 1 can be fixed on the guide rail by utilizing the mutual matching of the locking piece 2 and the buckle 11. Based on the above, the structure of the locking piece 2 is optimized, so that the casing 1 and the guide rail are convenient to assemble and disassemble, and a user can overhaul and maintain the casing conveniently.
In particular, because the locking piece 2 of the device has a simple integral structure, the locking piece is driven to move upwards by the spring 6, and is driven to move downwards by tools such as a screwdriver, the installation or disassembly task can be completed, compared with the prior art, the locking piece 2 has a more simplified structure, is convenient to produce and manufacture, and can thoroughly solve the problem that the circuit breaker loses the fixing capability due to the breaking of the clamping legs.
On the basis of the scheme, the bottom of the shell 1 is also provided with the supporting piece 3, so that the supporting piece 3 is conveniently used as a fulcrum for prying the locking piece 2 by a screwdriver, so that a user can conveniently drive the locking piece 2 to move, and meanwhile, the supporting piece 3 is movably connected with the shell 1, so that the supporting piece 3 is conveniently installed and replaced.
Specifically, since the support member 3 includes the support plate 9, the support plate 9 is in threaded engagement with the internally threaded hole 8 provided in the housing 1 through the externally threaded post 10 provided. Therefore, the rotation of the supporting plate 9 can be utilized to adjust the gap between the upper surface of the supporting plate 9 and the lower bottom surface of the shell 1, so that when the supporting piece 3 is used as a supporting point, the height of the supporting point can be adjusted, and the user can conveniently promote the locking piece 2 to slide. In addition, the external thread column 10 is in threaded fit with the internal thread hole 8, so that the phenomenon of vertical sliding of the rotated position of the supporting plate 9 can be avoided, and the position of the supporting point is stable and reliable.
On the basis of the scheme, the locking piece 2 is also provided with a supporting seat 4, and the bottom of the shell 1 is also provided with a fixing hole 13; wherein, one end of the spring 6 is installed in the supporting seat 4, and the other end of the spring 6 is installed in the fixing hole 13. Because the both ends of the spring 6 can be fixed by the support base 4 and the fixing hole 13, the problem that the lock 2 is reset and fails due to the displacement of the spring 6 when the lock 2 slides is avoided.
Further, in order to ensure smooth up and down of the locking member 2, a sliding groove 7 is further provided at the bottom of the housing 1, and the locking member 2 slides in the sliding groove 7, so that the sliding groove 7 can be used to stabilize the sliding position of the locking member 2.
Furthermore, since the surface of the locking member 2 facing the housing 1 is configured as an inclined surface, the locking member 2 can easily enter the guide rail, and the stability of the connection between the locking member 2 and the guide rail can be further enhanced.
The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to 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 utility model, and yet fall within the scope of the utility model.
