Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevator accessories, in particular to an elevator external calling plate with increased service life. Background Art
[0002] The elevator external call panel, also known as the elevator call button or elevator floor button, is a device installed outside the elevator car for passengers to call the elevator on each floor of the building. When the passenger presses the corresponding floor button, the elevator will receive the signal and stop at that floor so that the passenger can enter the car.
[0003] The micro switch on the elevator external call panel is an important control component, which ensures that when the passenger presses the call button, the elevator can respond and reach the designated floor. However, the micro switch is also one of the components most susceptible to pressure damage. The fundamental reason is that the micro switch of the elevator external call panel is the part that is frequently pressed during elevator use. With the increase in the number of uses, and if the passenger uses excessive force or maliciously damages it, the micro switch may be physically damaged. For this reason, we provide an elevator external call panel with a longer service life. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Example: See Figures 1 to 5 According to an embodiment of the utility model, a technical solution is provided: an elevator external call plate with improved service life, comprising a plate body 1, a micro switch 2 and a pressing assembly 3, wherein the plate body 1 can be installed on the wall outside the elevator entrance by bolts or bonding; the micro switch 2 is fixedly installed on the plate body 1 and has a pressure receiving part 20 that receives an external pressure signal; the pressing assembly 3 includes a rotating member 30 rotatably connected to the plate body 1 around a rotation axis and at least one pressing part 31 provided on the rotating member 30, and the at least one pressing part 31 is configured to be able to press the pressure receiving part 20 when the rotating member 30 rotates around the rotation axis to transmit a pressure signal to the pressure receiving part 20. It can be understood that the pressing portion 31 at least partially protrudes from the outside of the rotating member 30, so that the pressing portion 31 can press the pressure receiving portion 20 of the micro switch 2 when the rotating member 30 rotates. With the pressing assembly 3 of this structure, since the movement stroke of the pressing portion 31 toward the micro switch 2 is limited by the connection method between the rotating member 30 and the plate body 1, the pressing portion 31 on the rotating member 30 can be prevented from excessively pressing the micro switch 2, thereby extending the service life of the elevator external call plate.
[0028] In this exemplary embodiment, the pressing part 31 is a columnar body, and the pressing part 31 is rotatably connected to the rotating member 30 around a rotation axis 2, and the rotation axis 2 passes through the axis of the pressing part 31 and is parallel to the rotation axis 1. By rotating the pressing part 31 to the rotating member 30, the pressing part 31 and the pressure receiving part 20 of the micro switch 2 are in rolling contact when relative motion occurs. The use of rolling contact can effectively reduce the mutual wear between the two, and further extend the service life of the elevator external call plate.
[0029] In this exemplary embodiment, the rotating member 30 is provided with a mounting groove 300 inwardly concavely on its exterior, and the pressing portion 31 is rotatably connected to the mounting groove 300 via a rotating shaft 1 32 and partially protrudes from the mounting groove 300. The arrangement of the mounting groove 300 allows the pressing portion 31 to be embedded and installed on the rotating member 30, thereby making the structure of the pressing assembly 3 more compact. In addition, a hole for installing the rotating shaft 1 32 can be directly provided on the rotating member 30, which facilitates the assembly of the rotating shaft 1 32.
[0030] In this exemplary embodiment, the plate body 1 is provided with a mounting hole 10, and the rotating member 30 is rotatably connected in the mounting hole 10 through a rotating shaft 2 33 and partially protrudes from the mounting hole 10. The arrangement of the mounting hole 10 allows the rotating member 30 to be embedded and installed on the plate body 1, thereby making the structure of the elevator external call plate more compact. In addition, a hole for installing the rotating shaft 2 33 can be directly arranged on the plate body 1, which facilitates the assembly of the rotating shaft 2 33.
[0031] In this exemplary embodiment, an anti-skid structure is provided on the outside of the portion of the rotating member 30 protruding from the mounting hole 10 when the rotating member 30 is installed. By providing the anti-skid structure, the friction between the finger and the rotating member 30 can be increased when the user moves the rotating member 30 with a finger, thereby ensuring the normal use of the micro switch 2. Specifically in this embodiment, the anti-skid structure is an anti-skid pattern 301 provided on the outside of the portion of the rotating member 30 protruding from the mounting hole 10. In other embodiments, the anti-skid structure can also be rubber or other anti-skid materials provided on the rotating member 30.
[0032] In this exemplary embodiment, two pressing parts 31 are provided, and the two pressing parts 31 are respectively located on both sides of the pressure receiving part 20. In specific applications, when the user pushes the rotating member 30 upward, one of the pressing parts 31 can contact and trigger the micro switch 2, and when the user pushes the rotating member 30 downward, the other pressing part 31 can contact and trigger the micro switch 2. Whether the rotating member 30 is pushed upward or downward, the micro switch 2 can be triggered, which can ensure that the micro switch 2 is triggered smoothly.
[0033] In this exemplary embodiment, the rotating member 30 has a first position and a second position on the plate body 1. When the rotating member 30 is in the first position, the pressing portion 31 does not contact the pressure receiving portion 20. When the rotating member 30 is in the second position, the pressing portion 31 presses the pressure receiving portion 20. A torsion spring (not shown) suitable for elastically maintaining the rotating member 30 in the first position is provided between the rotating member 30 and the plate body 1. By providing the torsion spring, it can be ensured that after the force driving the rotating member 30 to rotate is withdrawn, the rotating member 30 can automatically reset to the first position, avoiding the accidental touch of the micro switch 2, and ensuring the normal use of the elevator external call plate.
[0034] Working principle: The plate body 1 of the elevator external call plate is installed in the reserved installation position on the wall outside the elevator entrance by bolts or bonding, and the electricity is connected. After that, the user drives the extrusion part 31 on the rotating member 30 on the pressing component 3 to move, and triggers the micro switch 2 of the elevator external call plate through the extrusion part 31, so as to control the position of the elevator. Since the rotating member 30 is connected to the plate body 1 by a rotational connection, the movement stroke of the extrusion part 31 in the direction of the micro switch 2 is limited, which can prevent the extrusion part 31 on the rotating member 30 from excessively squeezing the micro switch 2, so that the elevator external call plate of this structure has a longer service life.
[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
