Description

Novel LED indoor bottom shell

Technical Field

The utility model relates to the technical field of LED accessories, in particular to a novel LED indoor bottom shell.

Background

In the existing LED display screen module product below the indoor Q3.0, the bottom shell and the PCB are installed and fixed through automatic locking screws from the back of the bottom shell. However, the general bottom case needs to lock 50 screws in 5 rows and 10 columns, and the number of screws is large, which results in high product cost and low assembly efficiency. Meanwhile, the bottom shell is generally made of plastic, so that the problem that the screws outside the module in the long axis direction are prone to deviation when the screws are locked is caused due to the influences of thermal expansion and cooling and tolerance deviation.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel LED indoor bottom shell which can reduce the number of locking screws and avoid the influences of thermal expansion and cooling and tolerance deviation when the screws are locked, so that the product cost is reduced, and the efficiency and the quality of screw locking are improved.

In order to achieve the above purpose, the solution of the utility model is:

the utility model provides a novel indoor drain pan of LED, includes the drain pan body, the drain pan body is provided with 36 locks and pays the hole, and 36 locks pay the hole edge the major axis direction of drain pan body is 4 rows of 9 and arranges, just the cross-section in 2 rows of locks of the major axis direction both ends outside of drain pan body is oval, oval lock pay the oval major axis in hole with the major axis direction of drain pan body parallels.

The bottom shell body comprises an outer frame and an inner frame, the outer frame is rectangular, the inner frame comprises 2 rows and 3 rows of crisscross connecting beams, and the end parts of the connecting beams are connected to the inner side of the outer frame.

In the locking holes, the outermost locking hole is arranged on the outer frame, the rest locking holes are arranged on the inner frame, and the distances among the locking holes are the same.

Reinforcing ribs are arranged on two sides of the connecting beam, and the reinforcing ribs surround the connecting beam in the transversely and longitudinally staggered positions to form a square.

After the technical scheme is adopted, the number and the positions of the locking holes of the bottom shell body are rearranged, and the bottom shell body is designed into 36 in 4 rows and 9 columns, so that the product can be manufactured and operated more quickly, the production efficiency is improved, and the production cost is reduced; meanwhile, the cross sections of the 2 rows of locking holes on the outermost sides of the two ends of the long axis of the bottom shell body are all oval, so that the adjusting space which is larger and moves left and right when the screw is aligned is formed, and the deviation of the screw caused by expansion with heat and contraction with cold and tolerance deviation of a plastic part is avoided, so that the quality of the locking screw is ensured.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

The utility model relates to a novel LED indoor bottom shell, which comprises a bottom shell body 1, wherein 36 locking holes 2 are formed in the bottom shell body 1, the 36 locking holes 2 are arranged in 4 rows and 9 rows along the long axis direction of the bottom shell body 1, the cross sections of the 2 rows of locking holes 2 on the outermost sides of the two ends of the bottom shell body 1 in the long axis direction are all oval, and the oval long axes of the oval locking holes 2 are parallel to the long axis direction of the bottom shell body 1.

Referring to fig. 1 and 2, a specific embodiment of the present invention is shown.

The bottom shell body 1 comprises an outer frame 3 and an inner frame 4, wherein the outer frame 3 is rectangular, the inner frame 4 comprises 2 rows and 3 rows of connecting beams 5 which are staggered transversely and longitudinally, and the end parts of the connecting beams 5 are connected to the inner side of the outer frame 3.

Furthermore, the locking hole 2 at the outermost ring is arranged on the outer frame 3, the other locking holes 2 are arranged on the inner frame 4, and the distances among the locking holes 2 are the same, so that the relatively balanced stress of all positions of the bottom shell is realized during the locking of the screw.

Furthermore, reinforcing ribs 6 are arranged on two sides of the connecting beam 5, and the reinforcing ribs 6 surround a square at the position where the connecting beam 5 is staggered transversely and longitudinally, so that the structural strength of the staggered position of the connecting beam 5 is enhanced.

Through the scheme, the number and the positions of the locking holes 2 of the bottom shell body 1 are rearranged, and the number of the locking holes is 36, namely 4 rows and 9 columns, so that the product can be manufactured and operated more quickly, the production efficiency is improved, and the production cost is reduced; meanwhile, the cross sections of the 2 rows of locking holes 2 on the outermost sides of the two ends of the long axis direction of the bottom shell body 1 are all oval, so that the adjusting space which is larger and moves left and right when the screw is aligned is formed, and the deviation of the screw caused by expansion with heat and contraction with cold and tolerance deviation of a plastic part is avoided, so that the quality of the locking screw is ensured.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
