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.

Referring to fig. 1-5, an embodiment of the present utility model is provided: the mounting box for the circuit breaker comprises a box body 12, wherein the box body 12 comprises a bottom box 1 and a face box 3 connected with the bottom box 1; a first preformed hole 5 is formed in one side of the bottom box 1, a second preformed hole 9 is formed in the other side of the bottom box 1, and sealing covers 2 are arranged on the first preformed hole 5 and the second preformed hole 9; the face box 3 is also provided with a mounting area 10, and the mounting area 10 is connected with a box door 4 arranged on the face box and is closed by closing the box door 4 so as to seal the mounting area 10.

In summary, since the first preformed hole 5 and the second preformed hole 9 are directly formed on the case 12, the preformed holes can be formed in the bottom case 1 before the case 12 is manufactured, so as to reduce the problem of damage to the surface of the case 12 caused by forming the wire harness holes in the field; meanwhile, the first preformed hole 5 and the second preformed hole 9 are sealed by the sealing cover 2 in a normal state, so that dust in the transportation and storage processes of the box body 12 cannot enter the box body 12, and meanwhile, when the box body 12 is in use and does not need the used preformed holes, the dust can be prevented from entering the box body 12 by the sealing cover 2.

In addition, the number of the second preformed holes 9 is two, and the number of the first preformed holes 5 is one, so that the wire harness can enter the box body 12 from different preformed holes, and a user can conveniently access the wire harness into the box body 12 according to the trend of the wire harness.

Further, due to the arrangement of the reserved holes, the box body 12 is more convenient for inserting the wire harness, and meanwhile, the arrangement of the box door 4 is convenient for inserting the wire harness into the box body 12 and simultaneously can reduce dust entering the box body 12.

On the basis of the scheme, the installation area 10 is internally provided with the shaft pin seat 6, and the box door 4 is in shaft pin connection with the shaft pin seat 6 through the shaft pin hole 43; a first buckle 7 is further arranged in the installation area 10; after the door 4 is closed, the first buckle 7 is connected with a second buckle 41 provided on the door 4.

Through the mode, the box door 4 is convenient to open and close on the box body 12, and the box body 12 is closed and then under the action of the two buckles, the phenomenon that the box door 4 is automatically opened is avoided.

Furthermore, the installation area 10 is further provided with the lock column 8, and the lock column 8 passes through the slot 40 provided on the door 4 and is exposed outside the door 4, so that the lock can be hung on the lock column 8 to reliably fix the door 4 on the box 12, thereby avoiding the problem of safety accidents caused by the door 4 being opened by idle people.

In order to facilitate the opening of the door 4, the door 4 is further provided with a finger hole 42, when a finger is inserted into the finger hole 42, the door 4 is moved upwards to easily separate the first buckle 7 from the second buckle 41, so that the door 4 is opened conveniently, and conversely, after the first buckle 7 is connected with the second buckle 41, the door 4 can be fixed.

Based on the above, the box door 4 is convenient to open and close, and the phenomenon that the box door 4 is automatically opened can be effectively avoided after the box door is closed, so that the safety of the internal equipment of the box body 12 during use is ensured.

Further, since the middle part of the box door 4 is further provided with the see-through area 44, and the see-through area 44 is provided with the transparent plate, the user can know the working state of the electric components in the box body 12 conveniently in the state that the box door 4 is not opened.

In order to facilitate the assembly of the face box 3 and the bottom box 1 and the fixation after the assembly, through holes 11 are formed in four corners of the face box 3, and bolts penetrate through the through holes 11 and then are connected with threaded holes 13 formed in the bottom box 1, so that the face box 3 and the bottom box 1 are assembled.

Further, since the through hole 14 is provided in the bottom case 1, and the through hole 14 is connected with the reserved bolt, so that the case 12 is fixed on the supporting surface, the bottom case 1 can be fixed on the supporting surface, so that the whole fixing of the case 12 is realized, and in addition, the cross section of the through hole 14 is elliptical, so that the bottom case 1 is convenient to be connected with the reserved bolt on the wall surface.

Furthermore, since the bottom case 1 faces the insert plate 15 on the surface of the face case 3, the insert plate 15 is adapted to be connected with a slot (not shown) provided on the bottom case 1. So that the contact surface of the bottom case 1 and the face case 3 is more, to reduce the entry of dust into the case 12. In addition, the water flow direction inside the box body 12 can be reduced to improve the waterproof capability of the box body 12, and when the sealing ring is arranged in the slot, the waterproof performance of the device can be further improved after the face box 3 is connected with the bottom box 1.

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.
