Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a combined distribution box. Background Art

[0002] A distribution box is a closed or semi-closed metal box that is assembled with switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment according to electrical wiring requirements. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In the event of a fault or abnormal operation, the circuit can be cut off or an alarm can be sounded with the help of protective electrical appliances. Large distribution boxes usually adopt a modular design, in which the distribution equipment and the box are combined by mounting, thus forming a mounting connection method.

[0003] When performing combined mounting of the distribution box, the door of the distribution box needs to be kept open to facilitate the mounting operation of the staff. When the operator opens the distribution box door, he usually restricts the rotation of the door by using external objects to abut against it, thereby ensuring that the door is open. However, this setting has poor stability and is inconvenient to operate. Therefore, we propose a combined distribution box to solve the above problem. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a combined distribution box to solve the problem that the rotation of the door is restricted by abutting with external objects, thereby ensuring that the door is opened in an inconvenient manner.

[0006] The outer protective door rotates relative to the connecting hinge, and the limiting rod can be pushed horizontally to slide along the limiting rod sliding groove and extend outward, and the extended end portion limits the rotation of the outer protective door.

[0007] Preferably, the connecting hinge is fixed to the outer box surface of the distribution box by bolts, and the outer protective door is rotatably connected to the connecting hinge.

[0008] Preferably, a through hole is provided at the end of the connecting hinge for the restriction rod to move transversely therethrough, and the through hole has the same specifications as the restriction rod, and the opening positions of the through hole and the restriction rod sliding groove correspond to each other.

[0009] Preferably, the end of the limiting rod that contacts the outer protective door is designed with a rounded corner, and the limiting rod and the limiting rod sliding groove are fixed by friction.

[0010] Preferably, the opening of the limiting hole and the end of the limiting rod have the same diameter, and both the opening of the limiting hole and the end of the limiting rod are rounded.

[0018] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0019] Example:

[0020] See also Figure 1 - Figure 4 , a combined distribution box, including an outer box body 1 of the distribution box, an outer protective door 2 rotatably connected to the outer box body 1 of the distribution box, an inner protective door 3 rotatably connected to the inside of the outer box body 1 of the distribution box, the outer box body 1 of the distribution box and the outer protective door 2 are rotatably connected through the outer protective door rotation limiting assembly 4, the outer protective door rotation limiting assembly 4 includes a connecting hinge 41 respectively connecting the outer box body 1 of the distribution box and the outer protective door 2, the connecting hinge 41 is fixed to the surface of the outer box body 1 of the distribution box by bolts, the outer protective door 2 is rotatably connected to the connecting hinge 41, a limiting seat 42 provided on the surface of the connecting hinge 41, a limiting rod slide groove 43 provided inside the limiting seat 42, a limiting rod 44 sleeved inside the limiting rod slide groove 43, a limiting hole 45 provided at one end of the limiting rod 44, a limiting plug rod 46 provided in the middle of the limiting seat 42 to cooperate with the limiting hole 45 to form an embedded limiting structure, and a return spring 47 for driving the limiting plug rod 46 to move;

[0021] The outer protective door 2 rotates relative to the connecting hinge 41, and the limiting rod 44 can be pushed horizontally to slide along the limiting rod sliding groove 43 and extend outward. After extending, the end of the limiting rod 44 limits the rotation of the outer protective door 2.

[0022] A through hole is provided at the end of the connecting hinge 41 for the limiting rod 44 to move horizontally through, and the through hole has the same specifications as the limiting rod 44, and the opening position of the through hole corresponds to the limiting rod slide groove 43. The through hole can play a role in assisting in fixing the limiting rod 44 and ensuring the stability of the limiting rod 44 during the horizontal movement.

[0023] The end of the limiting rod 44 that contacts the outer protective door 2 is designed with a rounded corner. After the outer protective door 2 is rotated and opened relative to the outer box body 1 of the distribution box, the limiting rod 44 can be pushed to make the limiting rod 44 slide out along the limiting rod slide groove 43. After the end of the limiting rod 44 extends to the outside of the connecting hinge 41, it limits the rotation range of the outer protective door 2 to prevent accidental rotation of the outer protective door 2 from affecting the normal work of the staff. The limiting rod 44 is fixed to the limiting rod slide groove 43 by friction. In the retracted state, the limiting rod 44 can be fixed in the limiting rod slide groove 43 by friction, maintaining the relative stability of the set state.

[0024] The opening of the limiting hole 45 is consistent with the diameter of the end of the limiting rod 46, and the opening of the limiting hole 45 and the end of the limiting rod 46 are both rounded. When the limiting rod 46 on the limiting rod 44 moves horizontally to the position of the limiting hole 45, the limiting rod 46 moves and embeds into the limiting rod 44 under the elastic force of the return spring 47, forming an embedded fixed structure. Under the restriction of the limiting rod 46, the limiting rod 44 maintains its own position fixed, thereby limiting the maximum rotatable angle of the external protective door 2 and preventing the external protective door 2 from rotating.

[0025] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
