Abstract
The utility model relates to a vacuum sucking disc with magnetic attraction force. The utility model is designed for taxi sign lamps, particularly for sign lamps arranged and fixed on taxi roofs. A magnet, a magnetic conducting yoke plate and an iron core are arranged in a rubber vacuum sucking disc; when the sucking disc is sucked with a steel plate on a taxi roof to form a magnetic loop, a sucking surface lies in the state of vacuum negative pressure, and a fixing sucking disc has magnetic attraction force and vacuum attraction force. The increased adsorption force of the sucking disc rationally shares the stress of the sign lamps so as to enhance high speed driving safety of taxies.
Description
The utility model relates to installs the taxi sign lamp, particularly the vacuum cup of installation, fixed marker lamp on roof.
The monolateral fixed type marker lamp of public taxi adopts monolateral fixed support and vacuum cup aggregate erection usually, and monolateral fixed support and roof one side are fixed, and marker lamp is following to be supported by the rubber vacuum cup.Work as high vehicle speeds, marker lamp is subjected to wind effect, and vacuum cup suction is limited, can not guarantee the marker lamp location, and monolateral fixed support bears big load, often causes the failure, fractures, and causes marker lamp to come off.
For addressing this problem, take to strengthen monolateral fixed support usually, owing to be subjected to restrictions such as mounting means, vehicle are attractive in appearance, strengthen monolateral fixed support and often get half the result with twice the effort and be difficult to realize.
The purpose of this utility model provides a kind of sucker through improved sign supports lamp, and by increasing the adsorption affinity of this sucker, it is stressed to significantly reduce monolateral fixed support, and it can prevent effectively that fixed support from damaging even marker lamp comes off.
The utility model is to realize like this, pre-buried yoke plate, iron core in the rubber vacuum cup, add permanent magnetic iron again, magnet is close to yoke plate, transmits magnetic force by iron core, when sucker and roof adhesive, magnet, yoke plate and iron core are formed two and are hung down to by the magnetic pole of adhesive face (the S utmost point, the N utmost point), form magnetic loop with the roof steel plate, and make adhesive face be in vacuum negative pressure condition owing to got rid of air in the sucker, this just makes sucker have magnetic attraction and pull of vacuum concurrently, has strengthened the adsorption affinity of sucker greatly.
The utility model is with the combination of magnet and vacuum cup, and is simple in structure, processing, easy for installation, and cost of manufacture is cheap, and that the adsorption affinity that sucker increases has reasonably been shared marker lamp is stressed, has strengthened the high vehicle speeds safety.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the section-drawing according to the vacuum cup of the carrying magnetic suction that the utility model proposes.
The details and the service condition of the concrete device that foundation the utility model proposes are described below in conjunction with Fig. 1.
This device comprises a rubber suction cups (1), pre-buried one circular yoke plate (2) in the sucker, and yoke plate and iron core (3) connect, and circular ring magnet (4) is close to yoke plate (2).
Rubber suction cups (1) is made the vacuum cup pattern, when sucker is inhaled in roof, make adhesive face be in vacuum negative pressure condition owing to got rid of air in the sucker, at this moment magnet (4), yoke plate (2) and iron core (3) are formed two and are hung down to by the magnetic pole of adhesive face (the S utmost point, the N utmost point), form magnetic loop with the roof steel plate, thereby make sucker have magnetic attraction and pull of vacuum concurrently.
Claims (2)
1. be the taxi sign lamp, in particular for the sucker of installing, fixed marker lamp design-calculated has magnetic attraction and pull of vacuum concurrently, Here it is is provided with magnet, magnetic conduction yoke plate and iron core in the rubber vacuum cup, it is characterized in that adding in vacuum cup having put magnetic and inhaling the iron device.
2. device according to claim 1 is characterized in that sucker internal magnet, magnetic conduction yoke plate and two of iron core compositions hang down to by the magnetic pole of adhesive face (the S utmost point, the N utmost point), form magnetic loop when sucker and steel plate adhesive, and adhesive face are in vacuum negative pressure condition.
