The first protruding hull is provided to accommodate the socket, which relatively reduces the overall volume of the calling box, and the water is guided to the side of the bottom plate through the first guide to flow away, so it has a waterproof function.

Description

Hall call box for elevator

technical field

The invention relates to an elevator hall call box, which belongs to the field of elevator equipment.

Background technique

At present, the existing calling box consisting of a panel and a built-in box is inconvenient to install, so more and more wall-mounted calling boxes are used. However, the thickness of the wall-mounted calling box is relatively thin, and the gap between the internal electronic components and the installation base is small, so when cleaning the wall or returning to the south to generate condensed water, the water on the wall can easily enter the product through the installation hole on the installation base Internally, when the well leaks, water droplets enter the interior of the summoning box along the cable through the outlet hole of the summoning box, causing the product function to fail.

Contents of the invention

Based on this, the present invention overcomes the defects of the prior art and provides an elevator hall call box with simple structure and convenient installation. overall volume of the box.

Its technical solution is as follows: a call box outside the elevator hall, including a base plate, the base plate has a first protruding hull, the first convex hull is provided with wiring holes, and the first convex hull is also There is a first flow guide connected to the side of the bottom plate.

Preferably, the first convex is located in the middle of the bottom plate, and can guide most of the water above to both sides of the first convex to flow away.

Preferably, the first deflector is a rib groove.

Preferably, the ribs are herringbone-shaped, and can guide the water on the first convex hull into the ribs, and be transported to the side of the bottom plate by the ribs.

Preferably, the wiring hole is opened on the lower end surface of the first protrusion, so that the socket is inserted into the wiring hole facing upwards, which can prevent the wires of the socket from diverting water into the wiring hole and then into the calling box.

Preferably, the bottom plate also has a concave second convex hull, and a mounting hole is opened on the second convex hull, and the mounting hole is concave, so that the mounting hole can be separated from the wall, and the water on the wall can be prevented from flowing into the wall. The mounting holes go into the summon box.

Preferably, the second protrusion has a second flow guide connected to the side of the bottom plate, and guides the water flowing to the installation hole to the side of the bottom plate through the groove connected thereto.

Preferably, the second deflector is a rib groove.

The principle and effects of the aforementioned technical solutions are explained below: the first convex hull is provided with a protruding first convex hull, which can accommodate the socket and relatively reduce the overall volume of the calling box, and the first convex hull has a The concave first deflector guides the water to flow away from the side of the bottom plate through the first deflector, so it has a waterproof function.

Detailed ways

Embodiments of the present invention are described in detail below:

As shown in Figures 1 to 2, a call box outside the hall for an elevator includes a bottom plate 1 with a first protruding hull 2 on the bottom plate 2, and a wiring hole is provided on the first convex hull 2. 21. The first convex hull 2 also has a first flow guide 5 connected to the side of the bottom plate 1, the first flow guide 5 is a rib groove, and the rib groove plays the role of water guide. A first protruding hull 2 is provided, the first convex hull 2 can accommodate the socket, relatively reducing the overall volume of the calling box, and the first convex hull 2 has a concave groove connected to the side of the bottom plate 1 , the water is directed to the side of the bottom plate 1 to flow away through the rib groove, so it has a waterproof function. Among them, "concave" means concave toward the inside of the calling box, and "convex" means convex toward the outside of the calling box.

The first convex hull 2 is located in the middle of the bottom plate 1 and can guide most of the water above to both sides of the first convex hull 2 to flow away. The rib groove is herringbone, and can guide the water on the first convex hull 2 into the rib groove, and be transported to the side of the bottom plate 1 by the rib groove. The wiring hole 21 is arranged on the lower end surface of the first convex hull 2, so that the socket is inserted into the wiring hole upwards, which can prevent the wires of the socket from diverting water to the wiring hole and then flow into the calling box. Described base plate 1 also has the second convex shell 3 of indentation, has mounting hole 31 on the second convex shell 3, and mounting hole 31 is concave, can make mounting hole 31 be separated from wall surface, can prevent wall surface The water enters in the summoning box by mounting hole 31. The second protrusion 3 has a second deflector 4 connected to the side of the bottom plate 1. The second deflector 4 is a rib groove, and the water flowing to the installation hole 31 is passed through the rib groove connected to it. Guide the side of bottom plate 1 to flow away.

The above-mentioned embodiments only express the specific implementation manner of the present invention, and the description thereof is relatively specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
