Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of upper cover, especially relate to the upper cover convenient to install. BACKGROUND

[0002] The line pressing cover is a component of the network information module, which is mainly used for pressing operation on the core wire and is a key component for ensuring the stability of network connection. In the network information module, the effective connection of the core wire is very important, and the line pressing cover undertakes this responsibility. However, the existing line pressing cover has a fixed size design when pressing the core wire, which means that it can only adapt to a specific size of core wire. For core wires of different sizes or other special requirements, the fixed size line pressing cover may not be able to complete the pressing task well, resulting in poor universality and limiting the application of the network information module in various complex network connection scenarios to some extent.

[0003] The Chinese patent with publication number "CN213584311U" discloses a line pressing cover, which includes an upper cover and a lower cover. The upper cover and the lower cover are fixed by buckling. The upper cover includes an upper cover body and an upper chuck movably connected to the right side of the upper cover body. The front end of the upper cover body is provided with a first rotating shaft, and the rear end of the upper cover body is provided with a slide with an inner recess structure. The left and right ends of the slide are respectively provided with left and right limiting grooves arranged along the vertical direction. The bottom ends of the left and right limiting grooves are open structures. The upper chuck slides in the slide. The upper chuck includes an upper slide plate and an upper pressing block extending outward from the rear side of the upper slide plate. The left and right sides of the upper slide plate are respectively provided with left and right limiting blocks which slide in the left and right limiting grooves. The line pressing cover provided by the utility model has an upper chuck which is movable and can be used for positioning different sizes of core wires in the line pressing cover. Then, the core wires are further fastened by a strap, and the line pressing cover has strong universality.

[0004] The upper cover mentioned above does have convenience to some extent during actual application, however, some obvious deficiencies are exposed in the specific use process. First, the overall structure adopts a hinged mode to assist in installing the upper cover, and this installation mode has a big problem in the use process, that is, when the upper cover is damaged, the disassembly and replacement will become extremely inconvenient. Due to the limitation of the hinged structure, the upper cover is difficult to be easily detached from the network information module, which undoubtedly brings great trouble to the maintenance and replacement work. Secondly, the upper cover adopts a fixed connection mode, which makes it impossible to quickly open the upper cover during the overall use process. When the core wire inside the network information module needs to be checked, adjusted or repaired, the fixed connection of the upper cover will hinder the smooth operation and reduce the work efficiency. It can be seen that the existing design of the upper cover has certain defects in actual use, and needs to be improved to improve the practicability and convenience of the network information module.

The upper cover body 4 is mounted on the bottom of the mounting mechanism 6. Therefore, as the mounting mechanism 6 moves up and down, the upper cover body 4 can be opened or closed very flexibly. This design makes the overall opening and closing of the upper cover body 4 more convenient, which can significantly improve the overall convenience of use of the device.

[0030] By setting the mounting mechanism 6, so that the device during use, when the upper cover body 4 down to fit on the top of the bottom shell 3, at this time the support arm 647 can be inserted into the inside of the support sleeve frame 648, the support arm 647 and the support sleeve frame 648 are limited to each other, that is, the left and right transverse of the upper cover body 4 can be stably limited, and the up and down of the upper cover body 4 is limited by the screw rod 52 and the sliding block 53, thereby enabling the upper cover body 4 to stably cover the top of the bottom shell 3. During use, if you need to open the upper cover body 4, you can adjust the pull bridge handrail 645 to drive the limiting block 649 to extrude the limiting spring 643 to shrink, and the limiting block 649 moves up to separate from the inside of the limiting groove 642. At this time, the sliding plate 62 can be pulled out from the inside of the horizontal rail 61, which facilitates the disassembly and assembly of the upper cover body 4. When you need to install the upper cover body 4, you only need to insert the horizontal plate into the inside of the horizontal rail 61. At this time, the sliding plate 62 will extrude the guide slope 646, and after the guide of the guide slope 646, the limiting block 649 will extrude the limiting spring 643 to shrink. When the sliding plate 62 is completely immersed in the inside of the horizontal rail 61, the limiting block 649 and the limiting groove 642 are in contact with each other. At this time, the limiting spring 643 resets to drive the limiting block 649 to move down and insert into the inside of the limiting groove 642. The limiting block 649 and the limiting groove 642 are limited to each other, thereby enabling the upper cover body 4 to be clamped and installed. It can be seen that the disassembly and assembly of the upper cover body 4 of the device during use are relatively convenient, which can further improve the practicality of the device during use.
