Description

Technical Field

[0001] This utility model relates to the field of controller device technology, specifically to a detachable and rotatable dual-purpose cover plate mechanism. Background Technology

[0002] Controller modules (PLCs) are commonly used in industrial automation control. They generally include a base and side covers. The covers are usually pivotally connected to one side of the top surface of the base. When maintenance is required, the covers can be rotated to make room. The drawback is that the rotation of the covers requires space. When multiple controller modules are installed compactly or when the controller modules are in a narrow space, the rotation of the covers is easily restricted, making maintenance inconvenient and inconvenient to use. Improvements are needed. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a detachable and rotatable dual-purpose cover plate mechanism, including a cover plate and a bottom shell. A connecting plate for docking with the cover plate is provided on the top side of the bottom shell. The cover plate includes a transverse part and a connected longitudinal part. The two ends of the longitudinal part are pivotally connected to the grooves provided on the corresponding connecting plates through pivots and can rotate left and right relative to the bottom shell. The groove walls below the two ends of the longitudinal part are in the shape of downward-extending slopes.

[0005] This design improves the docking structure between the cover plate and the bottom shell. A pivot connection is formed at the groove in the longitudinal part through a pivot. Correspondingly, the groove wall of the lower groove is improved to be a downward-extending slope. When the mechanism covered by the cover plate needs maintenance, the cover plate can be rotated directly when its rotation is unrestricted. When the rotation of the cover plate is restricted, a screwdriver can be pressed against the slope and slid down to the end of the upward-curving longitudinal part, thereby releasing the pivot connection at the end of the longitudinal part. Then the cover plate can be moved up and removed for convenient use.

[0006] Furthermore, the longitudinal portion has outwardly protruding legs on both sides, which are pivotally connected to the grooves in the connecting plate via pivots for easy docking.

[0007] Furthermore, a pivot is provided at the groove, and a pivot groove that mates with the pivot is provided on the leg.

[0008] Furthermore, a slot is provided at the side end of the lateral portion of the cover plate, a support plate is provided on the connecting plate, and a protrusion is provided at the side end of the support plate. When the lateral portion of the cover plate rotates to the support plate, the protrusion is inserted into the slot to limit the cover plate. The protrusion and the slot can limit the cover plate and improve stability.

[0009] Furthermore, a boss is provided on the support plate below the protruding column. The boss is located on the path of the horizontal part moving downward to limit the downward movement of the horizontal part. A limiting block is provided on the inner side of the vertical part above the rotation center point. When the horizontal part abuts against the boss, the limiting block abuts against the top surface of the connecting plate simultaneously to improve the structural stability of the cover plate.

[0010] Furthermore, a slot is provided on the side of the transverse portion for the end of the support plate to be inserted, and a groove is provided on the groove wall of the slot to help limit the range of motion of the cover plate and improve stability.

[0011] Furthermore, a push plate is provided on the top surface of the transverse portion corresponding to the vertical portion, so that the cover plate can be rotated by pressing the push plate with a screwdriver, which is convenient to use.

[0012] Furthermore, the connection between the transverse portion and the longitudinal portion forms an L-shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model improves the docking structure between the cover plate and the bottom shell, which is rotatable and easy to disassemble, suitable for various occasions, and convenient to use. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 , Figure 2 As shown, this example illustrates a detachable and rotatable dual-purpose cover mechanism, comprising a cover plate 2 and a bottom shell 1. The bottom shell is typically rectangular, with a connecting plate 10 extending longitudinally along the top edge of the bottom shell 1 for docking with the cover plate. The cover plate 2 includes a transverse portion 21 and a connected longitudinal portion 22. The ends of the transverse portion 21 and the longitudinal portion 22 are connected to make the cover plate 2 L-shaped. The two ends of the longitudinal portion 22 are pivotally connected to corresponding grooves formed on the connecting plate 10 via pivots 12. The cover plate 2 can rotate left and right relative to the bottom shell. Preferably, the two sides of the longitudinal portion 22 have outwardly protruding legs 28, with pivot grooves 25 formed on the legs. A pivot 12 is formed on the bottom wall of the groove 16 of the connecting plate 10, and the pivot is pivotally connected to the pivot grooves on the legs.

[0023] Furthermore, in this example, the groove walls of the corresponding grooves 16 below the ends on both sides of the longitudinal portion 22 are shaped like downward-extending slopes 15, such as... Figure 1 , Figure 2 As shown, when using the screwdriver, place the screwdriver tip against the ramp and slide it down to the support leg. Then, lift the support leg to disengage the pivot from the pivot groove. At this point, the cover plate can be removed. Of course, if there are no other mechanisms limiting the bottom shell, the cover plate can also be rotated directly to facilitate maintenance of the mechanism at the bottom shell.

[0024] As a limiting cover, in this example, a slot 23 is formed at the side end of the lateral portion 21 of the cover 2, a support plate 11 is formed longitudinally at the top surface of the connecting plate 10, a protrusion 14 is formed at the side end of the support plate 11, and a slot 24 is formed at the groove wall of the slot 23. The lateral portion of the cover rotates and the end of the support plate is inserted into the slot, and the protrusion is inserted into the slot to limit the cover.

[0025] A boss 13 can also be formed on the support plate 11 below the protruding column 14. If the boss 13 is on the path of the side of the transverse part 21 moving downward, it can limit the downward movement of the transverse part. A limiting block 27 can be formed on the inner side of the longitudinal part above the rotation center point. When the side of the transverse part abuts against the boss 13, the limiting block abuts against the top surface of the connecting plate 10 simultaneously, thereby improving the structural stability of the cover plate.

[0026] To facilitate rotating the cover, a push plate 26 can be formed protruding outward at the top surface of the corresponding transverse portion 21 above the longitudinal portion 22. When in use, a screwdriver can be used to press against the push plate to rotate the cover.

[0027] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
