Description

Technical Field

[0001] The utility model relates to the field of power boxes, in particular to a lifting and pulling opening structure of a power box. Background Art

[0002] A power box is an electrical device that converts 220-volt alternating current into a constant, stable, low-volt direct current. It generally inputs 220v and outputs 24v, 36v, 12v, and 5v for use in small electrical appliances. Because different household appliances on the market currently use different input voltages, most household appliances are equipped with a power box to prevent damage to the appliance caused by excessive power voltage. The power box needs to be regularly inspected and maintained during use to ensure its normal use.

[0003] Most of the power boxes currently in use are fixed with bolts to protect the normal use of the electrical components inside the power box. However, when the electrical components inside the power box fail and need to be disassembled for maintenance, it is inconvenient to disassemble and assemble, and the box cover is easy to buckle on the box body by itself, resulting in reduced work efficiency of maintenance personnel.

[0041] See also Figure 1-8 The utility model provides a lifting and pulling opening structure of a power box, which comprises:

[0042] A box cover 1, wherein at least one through hole 2 is provided at one end of the box cover 1, and sliding holes 3 are respectively provided on both sides of the other end of the box cover 1;

[0043] A box body 4, one end of which is provided with at least one card block 5, which is carded in the corresponding through hole 2, and both sides of the box body 4 are respectively provided with limiting protrusions 6, which are located in the sliding hole 3, and both sides of one end of the box body 4 are respectively provided with step surfaces 7, which are lower than the surface of the box body 4, and at least one vertically arranged plug hole 8 is provided on the step surface 7, and when the box cover 1 is opened, one end of the box cover 1 is plugged into the plug hole 8.

[0044] The box body 4 includes a bottom plate 41, both sides of the bottom plate 41 are connected to the side plates 42, the two ends of the bottom plate 41 are connected to the first end plate 43 and the second end plate 44, the block 5 is arranged on the first end plate 43, and the step surface 7 is located at the end of the side plate 42. The bottom plate, the side plate, the first end plate and the second end plate are integrally bent and formed, and the connection is more stable. The bottom plate, the other side plate, the first end plate and the second end plate form a rectangular structure with an open upper end.

[0045] The block 5 is an elastic block, and has a bent portion at the top. A limit block 9 is provided on one side of the block 5, and the limit block 9 abuts against the surface of the box cover 1. When the block is subjected to external force, the elastic block can be easily changed in position, so that the block can be easily separated from the through hole; the bent portion can prevent the block from separating by itself, and the limit block can be used to fix the box cover more firmly.

[0046] The first bent plates 10 are respectively disposed at both ends of the second end plate 44, the first bent plates 10 are parallel to the side plates 42, a gap is left between the first bent plates 10 and the side plates 42, and the first bent plates 10 and the side plates 42 are connected by at least one rivet 11. The top of the second end plate 44 has a second bent plate 12, and the second bent plate 12 is parallel to the bottom plate 41. The first bent plate and the second bent plate can serve the purpose of shielding the ends of the box cover and improving the sealing performance.

[0047] The bottom of the box cover 1 has a raised portion 13, and the raised portion 13 forms a cavity inside the box cover 1. This can increase the space between the box body and the box cover.

[0048] like Figure 1 In one embodiment, the protrusion 13 is wedge-shaped.

[0049] like Figure 5 In another embodiment, the protrusion 13 is trapezoidal.

[0050] Working principle: when the box cover 1 is opened, the box cover 1 is first lifted upward to separate the blocking block 5 from the through hole 2. At this time, one end of the box cover 1 is separated from the box body 4, and then the box cover 1 continues to be lifted upward, and the box cover 1 rotates around the limiting protrusion 6, and the positions of the sliding hole 3 and the limiting protrusion 6 also change until the limiting protrusion 6 contacts the left end of the sliding hole 3. At this time, one end of the box cover 1 is inserted into the insertion hole 8, so that the box cover 1 is fully opened; when the box cover 1 is closed, the box cover 1 is first lifted upward to separate the box cover 1 from the insertion hole 8, and the end of the box cover 1 contacts the step surface 7, and then the box cover 1 is rotated downward to make the through hole 2 and the blocking block 5 engage, completing the closure of the box cover.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
