Detailed Description

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments in the present application may be combined with each other; the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left" and "right" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the indicated position or element must have a specific orientation, be constituted in a specific orientation, and be operated, and thus, are not to be construed as limitations of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Embodiment 1, refer to fig. 1, 2, 3, 4, the utility model provides a drain pan, including body 1, body 1 has four lateral walls 101, all is equipped with atress portion on four lateral walls 101, atress portion is used for accepting external force. Of course, the two opposite side walls may be provided with the force-receiving portions.

Further, the force-receiving portion is a first groove 1011 disposed on the side wall 101, the first groove 1011 is elongated, and the first groove 1011 is disposed along the length direction of the side wall 101.

After the bottom shell is installed on the external box body, the first grooves 1011 are formed in the four side walls 101 of the body 1, so that the external acting force is applied to the first grooves 1011 conveniently, acting points are provided, and the bottom shell is detached from the box body conveniently.

The above design can also bring the following effects:

it is assumed that the thickness of the side wall 101 of the conventional body 1 is 2 mm. If the thickness is 2.5mm, the resulting product will shrink and deform after injection molding.

By providing the first groove 1011, for example, the thickness of the sidewall 101 can be 2.5mm, and the depth of the first groove 1011 can be 0.5mm, i.e. the wall thickness of the first groove 1011 is 2 mm. The thickness of the circumference of the first recess 1011 increases. The weight of the whole bottom shell is not increased greatly, and the whole thickness is basically unchanged. Through being equipped with the setting, can no longer receive injection moulding's limitation, and then can improve the intensity, the roughness of drain pan, solved the contradiction relation between drain pan lateral wall 101 intensity, thickness, the weight. The phenomenon that the strength and the thickness of the original bottom shell are not enough is solved, and the strength and the flatness of the bottom shell of the LED display screen are improved.
