Abstract

The utility model discloses a portable alarm pole for training and examination of driver, which is composed of a base, a sound system, a pole, an on-off switch, a pile positioning line, etc. The utility model is characterized in that after the automobile touching and pressing pole, the pole can automatically recover erectility; the utility model has the advantages of time saving, labour saving, simple structure, low cost, and convenient operation; when the pole is in the state of tilting, falling down, or automobile wheel pressing line, the utility model can respectively make different alarm signal sound to remind driver; the utility model can conduct the information feedback in time, which can be good for improving training effect and examinatorial accuracy; can be convenient to conduct centralized control. The portable alarm pole for training and examination of driver can be used in process of automobile driving, training and examining.

Description

Portable alarm pole for training and examination of driver

The utility model relates to a kind of improved driver training examination mark post device.Particularly a kind of portable mark post device that can produce alerting signal.Be applicable to driver training of various motor vehicle style and examination.

Present domestic motor vehicle driving training and the used mark post of examination are reinforcing bar or bamboo (wood) bar mostly, and base also is a substitute miscellaneous, and the place needs to draw the stake bit line with lime.Behind the automobile depression bar, bar promptly is out of shape or damages, and need have that the special messenger sets upright, alignment, brings very big inconvenience to use.Simultaneously, the driver can not in time know the misoperation degree again, has influenced training effect.Recently the photoelectricity monitoring mark post that occurs is installed on the permanent type place, and inconvenience changes place shape and mobile mark post, and cost is higher, can't be widely used in driver training at ordinary times.

Task of the present utility model is that a kind of improved driver training examination mark post device will be provided, it not only is easy to carry, place arbitrarily, combination in any, and can bump, press mark post or line ball at vehicle the time, produce alerting signal immediately, bumped at mark post, after the compressive strain, mark post can recover erectility automatically.

The utility model is made up of base, sound system, open and shut valve, mark post and stake bit line.Base is turtle shell shape, in the seat sonification system, open and shut valve and mark post retaining element is housed.Mark post is made up of special nylon plastic(s) bar and joint, and the joint bottom is by retaining elements such as wire rope, and is tension-stretched by the pretension of spring, stands on the base.The stake bit line is made up of semicircle type hollow rubber band and the inner continuous contact switch of assembling thereof and lead, and each segment length is divided into 1 meter, 3 meters, 5 meters three kinds, is abutted against the plug-in unit connection between each section, and sound system links to each other with connector in a bit line and the base.Therefore, mark post can use separately, also can be used in combination with the stake bit line.Sound system is made up of power supply, circuit board (integrated circuit block and an amplifying circuit that can produce minimum three kinds of different sound) and loudspeaker etc.Open and shut valve is made of the conducting strip of mark post lower end and two conducting strips that are fixed on the plastic casing.When the vehicle collision mark post, mark post tilts to overcome spring tension, drives the lower end conducting strip by wire rope, connects in the open and shut valve end switch down, connects the sound system circuit, sends a kind of chimes of doom; When vehicle overwhelms mark post, connect again and go up end switch in the open and shut valve, send another kind of chimes of doom.After vehicle bumped, presses, mark post self-return under the pre-tensile force effect of preloading spring was upright.When wheel piling bit line somewhere, herein contact switch is promptly connected circuit on the stake bit line, sends the chimes of doom different with bumping, press mark post.

The utility model novel structure is compared with above-mentioned known mark post device, and easy to use, time saving and energy saving, information feedback is timely, helps improving training effect, is convenient to promote the use of.But and centralized control, realize the robotization of driving examination.

The utility model has following accompanying drawing:

Fig. 1 cuts open synoptic diagram for the master of this device

Fig. 2 is this device vertical view

There is shown the structural relation of the portable driver training examination mark post device of reporting to the police.Housing 2 is an ironcasting, is turtle shell shape, upright flexible mark post 1 on the platform.Plastic casing 3 by screw retention on housing 2, in adorn four batteries and spring 4 etc.There is spring-leaf retainer 8 spring 4 lower ends, adjusts packing ring 9,12 and insulating mat 10 and guide ring 11 etc.Circuit board 20 is fixed on the plastic casing outside.Loudspeaker is installed in the window place of housing 2.17 are handle slidably, and 16 is the centralized control line socket.Link into an integrated entity with lead by principle of work between power supply, loudspeaker, circuit board, open and shut valve, stake bit line socket and the centralized control line socket each several part.

When using automatic mark post, at first install power supply, have outside handle one side direction, place calibration position to come into operation.When need are used the stake bit line, connect a good stake bit line and place on the graticule position.In using, during the run-off the straight of vehicle collision mark post,, make on the insulating mat 10 and move by wire rope 5, and compression spring 4, contacting with conducting strip 7 on the plastic casing by conducting strip 12, loudspeaker 19 is sounded, and knows this vehicle touching lever; As continue to travel and overwhelm mark post, make wire rope 5 continue to move on the pulling insulating mats 10, conducting strip 12 contacts with another conducting strip 6, and loudspeaker sends another kind of sound, and the alerting driver mark post falls.After vehicle passed through, mark post was under the effect of spring 4, and the self-return state of being kept upright disconnects open and shut valve simultaneously.The pre-tensile force of spring 4 can be by adjusting nut 13 and lock bolt 14 adjustment.During as wheel piling bit line, under external force, make the rubber strip distortion, the closing of contact in the band is connected circuit, and loudspeaker sends the special alert signal, remind driver's wheel line ball, after wheel leaves, under the elastic reaction of rubber strip, recover virgin state automatically, the contact disconnects, and interrupts alerting signal.
