Description

Elevator calling box

Technical Field

The utility model relates to an elevator accessory technical field especially relates to an elevator calling board.

Background

In a building provided with elevators, at least one elevator calling box is required to be assembled on each building and used for calling the elevators to ascend and descend. Prior art's elevator calling board mainly includes the casing, the panel, have subassemblies such as circuit board and the backplate of display screen, because do not set up insulating barrier between prior art circuit board and the backplate, so after the installation is accomplished, the circuit board touches the backplate easily and takes place the short circuit phenomenon, the elevator calling board of this kind of structure of prior art can not play fine waterproof function yet, outside water flows inside the calling board from the erection joint department of backplate easily, and then causes the influence to the normal use of calling board.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: the elevator calling board is not easy to short circuit and good in waterproof effect.

The utility model adopts the technical proposal that: the utility model provides an elevator calling board, includes panel, casing, has circuit board and the backplate of display screen, panel and backplate are installed two sides around the casing respectively, the circuit board sets up inside the casing, still be equipped with the insulating piece between circuit board and the backplate, just the mounted position department at backplate top is equipped with waterproof buckle.

Preferably, the insulation sheet is arranged on one surface of the circuit board close to the back plate, and the area of the insulation sheet is larger than that of the circuit board.

Preferably, the top of the back plate is obliquely arranged, two notches are formed in the top of the back plate, two protruding locking portions used for being respectively embedded into the two notches are arranged inside the shell, and the waterproof buckle plate is installed at the oblique position of the top of the back plate.

Preferably, the upper edge of the waterproof buckle plate is tightly matched with the shell.

Preferably, the button fixing structure further comprises a button and a button buckle, the button buckle is fixed on the shell, and the button penetrates through a through hole in the panel to be connected with the button buckle in a buckling mode.

Preferably, the panel is made of glass material, and the panel is fixed on the shell by gluing.

Compared with the prior art in the structure more than adopting, the utility model has the advantages of it is following: set up an insulating piece between circuit board and backplate, can separate circuit board and backplate like this, after installing like this circuit board can not contact with the backplate, greatly reduced the short circuit risk to set up waterproof buckle on backplate upper portion, block the junction of backplate and casing, rivers can not follow the junction between backplate and the casing on the casing like this and flow into in the casing, play fine water-proof effects.

Install the insulating piece on the circuit board, insulating piece simple to operate like this to the area is bigger than the circuit board, and the circuit board is difficult to more like this and backplate contact, greatly reduced the short circuit risk.

The top of the back plate is obliquely arranged, so that the back plate is convenient to install and can be better waterproof.

With the upper portion edge and the casing of waterproof buckle closely cooperate, like this both leakproofness are better, and then water-proof effects is better.

Adopt the button buckle, directly pass the panel joint with the button on the button buckle during the installation, simple to operate.

Adopt glass material to make the panel, it is more pleasing to the eye, fix firmly and convenient through sticky fixation on the casing moreover.

Drawings

Fig. 1 is the explosion sketch map of the elevator calling box of the utility model.

As shown in the figure: 1. a panel; 2. a housing; 3. a circuit board; 4. a back plate; 5. an insulating sheet; 6. a waterproof gusset plate; 7. a notch; 8. a raised locking portion; 9. a button; 10. the button is buckled.

Detailed Description

The present invention will be further described below with reference to specific embodiments, but the present invention is not limited to the following specific embodiments.

An elevator calling board comprises a panel 1, a shell 2, a circuit board 3 with a display screen and a backboard 4 in sequence, wherein:

the panel 1 is made of glass material, the panel 1 is fixed on the front surface of the shell 2 by gluing, and two through holes for the buttons 9 to pass through are arranged on the panel 1;

the display screen is characterized in that a screen hole for installing the display screen and a button 9 hole for installing the button 9 are formed in the shell 2, the button 9 can be adhered in the button 9 hole of the shell 2 or locked in the button 9 hole in the shell 2 through a fastener, the display screen is fixed on the shell 2 through the fastener, the circuit board 3 is arranged on the back surface of the display screen, the PVC insulating sheet 5 is arranged on one surface, away from the back plate 4, of the circuit board 3, the area of the insulating sheet 5 is larger than that of the circuit board 3, two convex locking parts 8 are arranged on the inner wall of the upper end of the shell 2, and each convex locking part 8 is provided with a locking hole;

backplate 4, the upper end is the slope setting to the upper end has set up two breachs 7, these two breachs 7 supply protruding locking part 8 embedding then installation on the

casing

2, and 4 upper portions of backplate have still installed a waterproof buckle 6 moreover, after the installation, closely cooperate between buckle upper end edge and the 2 inner walls of casing turn on the water.

During this application installation, all install panel 1, button 9 buckle, casing 2, circuit board 3 and the insulating piece 5 that has the display screen earlier, form the call box of having assembled, then install backplate 4 on the wall, hang the call box of having assembled from the top to one side earlier again, detain the hypotenuse of backplate 4 top, press the call box again and make it laminate with the wall body, attach two screws at call box lower extreme lock at last. And (5) finishing the installation.

And the edge of the waterproof buckle 6 is tightly matched with the shell 2, when water is left from the upper part of the shell 2, the water flows down along the waterproof buckle 6 and then flows down along the mounting backboard 4 to call the box, and cannot flow into the shell 2.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
