Description

The electronic pin of built-in type folding arm structure

The utility model relates to the electronic pin of a kind of built-in type folding arm structure.

Electronic pin is a mechanical alley stopping device in road inspection Fare Collection System and parking charge system; Electronic pin is made up of cabinet and transverse arm, and motor, reducing gear and transmission device are arranged in the cabinet, makes transverse arm turn to the upright position by horizontal level, or turns back to horizontal level.At the toll on the road and bridge station, owing to be mostly that outdoor, there are enough spaces at the scene, transverse arm can high erecting, so transverse arm can be the straight-arm bar.But,,, do not allow long-armed erecting owing in building, do not have enough height space as the underground parking in certain occasion; In order to satisfy instructions for use, the electronic pin of a kind of fitted outside folding-jib has appearred, this pin is hinged by outer arm and inner arm and forms, arranged outside at outer arm has linkage, when inner arm rotates vertical or returns level, then outer arm remains horizontal level, can satisfy like this in the place of condition restriction such as underground parking and use; Though the electronic pin of this kind folding-jib can satisfy the service condition of certain occasion, but the linkage that it exposes, what then show is very in disorder, irregular, the user wishes to have and a kind ofly both can satisfy the electronic pin of folding-jib of underground parking instructions for use again as the beautiful and clean pin of straight-bar.

The purpose of this utility model provides and a kind of the folding arm transmission device is arranged in the folding arm inner chamber, makes external structure clean and tidy, the electronic pin of built-in type folding arm structure of internal construction compactness.

For achieving the above object, the utility model is taked following design scheme: the electronic pin of a kind of built-in type folding arm structure, by outer arm, inner arm, casing constitutes, it is characterized in that: in the rear end of outer arm, be fixedly connected with the outer arm hinged component, in the inner arm front end, be fixedly connected with the inner arm hinged component, this inner arm hinged component is hinged by rotating shaft and outer arm hinged component, be protruding with torque arm at outer arm hinged component middle part, in the inner chamber of inner arm, be provided with pull bar, the torque arm of the front end of this pull bar and outer arm hinged component is hinged, the rear end and the casing of this pull bar are hinged, and the power shaft that stretches out in the rear end of inner arm and the casing is connected.

The pull bar two ends are provided with the adjustment screw rod, this pull bar with adjust screw rod for being threaded.

Pull bar hinged place in the inner arm rear end is provided with arc notch.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 3 is the utility model operating principle schematic diagram

Fig. 4 is that the utility model outer arm, inner arm connect the sectional structure schematic diagram

Fig. 5 overlooks the sectional structure schematic diagram for Fig. 4

As shown in Figure 1 and Figure 2, the electronic pin of folding-jib, transverse arm is made up of for two sections outer arm and inner arm, and when transverse arm was positioned at lower position, outer arm and inner arm were in line, stop vehicle pass-through, and when transverse arm was kicked up, inner arm went to the upright position, and outer arm still keeps horizontal direction, the height that the height restriction that has so just adapted to building, outer arm are lifted can be decided according to the effective height of building.

As shown in Figure 3, the operating principle of built-in type folding arm is to have designed a parallel-crank mechanism in the rectangular tube of inner arm compactly, promptly is made of AB bar-constitute by the A on the inner arm, B two are point articulated AB bar, BC bar, CD bar, DA bar; BC bar-constitute by the B on the outer arm, C two are point articulated; CD bar one constitutes by the C on the pull bar, D two are point articulated; DA bar-constitute by the D on the casing, A two are point articulated, the A point is a driving shaft, promptly with the reductor interlock of cabinet built-in motor; Because ABCD is parallelogram, when rotating inner arm (being the AB bar), the BC bar promptly can lift, and can remain parallelly with AD, and promptly outer arm is in the process of lifting, and it is remaining horizontal level; This design wonderfully is designed to a rod member (being the AB bar) to inner arm itself ingeniously, and outer arm is the BC bar, and miscellaneous part all is installed in the cavity of inner arm, and structure is very compact, without any linkage, makes the people feel that structure is marvellous in the outside, and new meaning is arranged.

As Fig. 4, shown in Figure 5:, the electronic pin of a kind of built-in type folding arm structure, by outer arm 1, inner arm 2, casing 3 constitutes, be characterized in: in the rear end of outer arm 1, be fixedly connected with outer arm hinged component 5, in inner arm 2 front ends, be fixedly connected with inner arm hinged component 12, this inner arm hinged component 12 is hinged by rotating shaft 13 and outer arm hinged component 5, be protruding with torque arm 6 at outer arm hinged component 5 middle parts, in the inner chamber 8 of inner arm 2, be provided with pull bar 4, the torque arm 6 of the front end of this pull bar 4 and outer arm hinged component 5 is hinged, the rear end of this pull bar 4 and casing 3 are hinged, and the power shaft 11 that stretches out in the rear end of inner arm 2 and the casing is connected.

Be provided with at pull bar 4 two ends and adjust

screw rod

7,10, this pull bar 4 and

adjustment screw rod

7,10 are for being threaded.Wherein pull bar 4 can be adjusted its length by the left and right sides screw thread at its two ends, keeps outer arm to be in horizontal level.

Pull bar 4 hinged places in inner arm 2 rear ends are provided with arc notch 9, make the rear end of pull bar 4 and casing 3 hinged by this arc notch 9, do not rotate and do not influence inner arm.

The folding arm transmission device cooperates inner arm 2, casing 3 to form by pull bar 4, outer arm hinged component 5, inner arm hinged component 12.

The utility model has the advantages that: the folding arm transmission device is arranged in the folding arm inner chamber, makes external structure whole Clean, the internal structure compactness, and simple in structure, easy to use.
