Description

Technical Field

[0001] The utility model relates to the technical field of blind people's street crossing buttons, in particular to a blind people's street crossing button device. Background Art

[0002] A blind person refers to someone with visual impairment. Visually impaired people are mainly divided into two categories: total blindness and partial blindness. Total blindness means that they lose response to light, while amblyopia means that the activities of blind people will be restricted due to visual impairment.

[0003] For example, the patent document with the announcement number CN 214671086 U discloses a pedestrian crossing button, including an outer shell, on which a display panel for indicating a crossing signal and a touch button for triggering the display panel to switch the crossing signal are respectively arranged, the touch button is fixedly connected to a second switch unit arranged in the outer shell, and a first switch unit is also fixedly connected to the inner wall of the outer shell, and the second switch unit is pushed close to or in contact with the first switch unit by pressing the touch button to trigger the display panel to switch the crossing signal. The utility model has a simple structure and reliable functions, and can solve the problems of poor contact caused by water seepage, rust, oxidation and other problems of existing mechanical switches by realizing conduction triggering through a reed switch, and has a long service life.

[0004] However, due to the limitation of its own structure, this structure can only be used for fixed installation and operation at the position of the signal light pole, and it is impossible to perform rapid disassembly and maintenance operations on a daily basis. At the same time, the equipment is an integral fixed installation structure, and it is impossible to perform rapid separation and assembly and use operations between the switch and the internal equipment position, which cannot meet daily use needs. Therefore, it is urgent to design a blind crossing button device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a street crossing button device for the blind, so as to solve the problem that the existing structure proposed in the above background technology can only be fixedly installed and used at the position of the signal light pole due to its own structural limitations, and cannot be quickly disassembled and maintained in daily life. At the same time, the equipment is an integral fixed installation structure, and it is impossible to quickly separate and assemble the switch and the internal equipment position, and cannot meet the daily use needs.

[0006] To achieve the above object, the utility model provides the following technical solution: a blind person crossing button device, comprising a semi-arc holder, the front of the semi-arc holder is fixedly connected to a limit cover, the front of the limit cover is provided with a retractable button block, one end of the retractable button block is fixedly connected to a conical button, and the front of the conical button is provided with a button frame;

[0007] A wiring socket is provided at the inner center of the semi-arc socket, and a signal controller is provided inside the wiring socket.

[0008] Preferably, the front side of the wiring seat is fixedly connected to a limiting seat, and the front side of the limiting seat is provided with a first contact connector.

[0009] Preferably, shrink rubber pads are provided on both sides of the limit seat, limit clamping strips are provided on the sides of the shrink rubber pads, and limit clamping grooves are provided on both sides of the limit cover.

[0010] Preferably, contraction springs are provided at both ends of the back of the contraction button block, and a second contact joint is provided at the center of the back of the contraction button block.

[0011] Preferably, a stretchable rubber cover is provided inside the button frame, and a button body is provided at the center of the stretchable rubber cover.

[0012] Preferably, tightening belts are provided at the upper and lower ends of the back of the semi-arc holder, and tightening joints are provided at the upper and lower ends of one side of the inner wall of the semi-arc holder.

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

[0014] The blind person's street crossing button device can make the device more suitable for installation and use by means of the semi-arc holder, limit cover, retractable button block, conical button, button frame, wiring seat, retractable spring, stretch rubber cover, button body, tightening belt and tightening joint. In actual use, the staff first clamps the semi-arc holder as a whole from the side of the signal pole with the wiring seat, so that the semi-arc holder can quickly cover and connect the side of the wiring seat, and then clamp the tightening belts at the upper and lower ends of the wiring seat at the tightening joint of the semi-arc holder, so as to quickly carry out the docking installation operation between the semi-arc holder and the signal pole position, which is convenient for the subsequent rapid disassembly and maintenance operation of the faulty semi-arc holder as a whole. At the same time, the blind person can directly press the hand inside the button frame of the conical button, and then the retractable button block is pressed and started by the retractable springs at the upper and lower ends of the back, and the design of the stretch rubber cover and the button body inside the button frame can carry out rapid hand positioning operation, so as to ensure that the blind person can complete the use operation of the street crossing button more easily, which reflects the practicality of the equipment design.

[0015] The blind person crossing button device further improves the overall use effect of the device by arranging a semi-arc holder, a limit cover, a retractable button block, a terminal holder, a signal controller, a limit holder, a first contact joint, a retractable rubber pad, a limit card strip, a limit card slot and a second contact joint. In daily use, when the semi-arc holder and the terminal holder are docked, the limit holder on the side of the terminal holder can be adaptively plugged into the inside of the limit cover, and then the limit card strip is first retracted by the retractable rubber pad, and then quickly docked to the limit card slots on both sides of the limit cover to perform an extended limit operation, thereby ensuring the tightness of the connection between the semi-arc holder and the terminal holder after the connection. At the same time, when the retractable button block is pressed and contracted by the retractable spring, the second contact joint at the center of its back can be accurately positioned and docked with the first contact joint on the front of the limit holder, thereby ensuring the accuracy of the switch and avoiding the problem of accidental touch due to short-term pressing, which reflects the comprehensiveness of the device design.
