Controlling the included angle between cross tubes that are connected in the center, so as to control the shrinkage movement of the road gate handler in a horizontal direction, thereby controlling the length of the road gate handler.
Description
Technical field
The present invention relates to a kind of restrictor bar, concrete relate to a kind of restrictor bar with stretching structure.
Background technology
At present, the restrictor bar that is widely used in each vehicle in and out port, charge station and parking lot all is a regular length, is to select restrictor bar length according to the width at control crossing.When the reduced width at crossing or when widening, the previous restrictor bar that uses can be long or too short, can't satisfy existing requirement, can only buy restrictor bar again, and need the professional to carry out Installation and Debugging, like this, both caused the loss of user's certain economic, also brought very big inconvenience to the user.Existing restrictor bar all is to be the center of circle with the end, rotatablely moves in level with vertically.Because horizontal level restrictor bar gravity torque maximum, and the restrictor bar gravity torque is zero when the upright position, in order not make the suffered moment variations of dynamical system too big, must use the gravity of spring balancing restrictor bar, like this, the restrictor bar of different length will be equipped with different springs, and after spring use a period of time fatigue, must regulate or the replacing spring, bring very big inconvenience to the user.In addition, need the place of maximum height limit at some, the restrictor bar of regular length can not satisfy user's needs, thereby has limited its scope of application greatly.
Summary of the invention
The present invention aims to provide a kind of restrictor bar of stretching structure, solve the problem of the uncontrollable restrictor bar length of existing restrictor bar, restrictor bar along continuous straight runs contractile motion of the present invention does not need to use spring balancing restrictor bar gravity, is not subjected to the restriction of height.
The restrictor bar of stretching structure of the present invention is to realize by following scheme: the restrictor bar of constructing a kind of stretching structure, comprise many cross pipes and coupled a plurality of connectors, interconnect with connector between cross pipe and the cross pipe, thereby form the body of rod with mutual cross connecting structure, it also comprises motor and the screw mandrel that links to each other with described motor, described screw mandrel opposite end has positive pitch thread and anti-pitch thread respectively, and two cross pipe ends of the described body of rod one end are connected with anti-pitch thread with the positive pitch thread of described screw mandrel respectively and are connected.
The restrictor bar of stretching structure of the present invention, it further comprises driving gear and the driven gear that meshes with described driving gear, and described driving gear is fixed in the output shaft of described motor, and described driven gear is fixed in described screw mandrel.
The restrictor bar of stretching structure of the present invention, two cross pipe ends of the described body of rod one end are connected by corresponding the connection with anti-pitch thread with the positive pitch thread of described screw mandrel of positive tooth nut and anti-tooth nut respectively.
The restrictor bar of stretching structure of the present invention, the chute that it further comprises horizontal fixed, the connector along continuous straight runs that is positioned at two cross pipe middle parts of the described body of rod one end is arranged at described chute slidably.
The restrictor bar of stretching structure of the present invention, described screw mandrel is provided with limit switch.
The restrictor bar of stretching structure of the present invention, described limit switch are two, are arranged at the opposite end of described anti-pitch thread respectively.

Specific embodiment
Below in conjunction with specific embodiment, be further elaborated.
As shown in Figure 1 and Figure 2, the restrictor bar of stretching structure of the present invention comprises cross pipe 15, cross pipe 16, cross pipe 19, cross pipe 20 and connector 14, connector 17, connector 18, connector 21, connector 22, connector 23.The middle part of the middle part of cross pipe 15 and cross pipe 16 interconnects by connector 14; The middle part of the middle part of cross pipe 19 and cross pipe 20 interconnects by connector 21; The end of the end of cross pipe 16 and cross pipe 20 interconnects by connector 18; The end of the end of cross pipe 15 and cross pipe 19 interconnects by connector 17; In like manner, the middle part of back one-level links to each other, and the cross pipe assembly passes through connector 22, connector 23 is connected with previous stage, up to the length of needs.
As shown in Figure 1, when banister restrictor bar full extension, motor 1 output shaft counterclockwise rotates, and driving gear 2 is rotated counterclockwise, 3 clockwise direction rotations of driven gear, drive the rotation of screw mandrel 6 clockwise directions, the distance between positive tooth nut 7 and the anti-tooth nut 8 becomes big, makes that the angle between cross pipe 15 and the cross pipe 16 becomes big, it is connector 11, connector 14, the angle that connector is 12 3 become big, and connector 14 is towards shrinking near screw mandrel 6 directions.Again because connector 14, connector 18, connector 21 and connector 17 constitute parallelogram, so the angle between cross pipe 19 and the cross pipe 20 also becomes greatly, promptly connector 17, connector 21, it is big that the angle that connector is 18 3 becomes, and connector 21 is also towards shrinking near screw mandrel 6 directions.In like manner, also towards agreeing that a direction shrinks, restrictor bar shrinks and shortens the cross pipe assembly of back level cascade like this, runs to the position of limit switch 10 up to anti-tooth nut 8, stops contraction, as shown in Figure 2.
As shown in Figure 2, when the banister restrictor bar shrinks fully, the rotation of motor 1 output shaft clockwise direction, the rotation of driving gear 2 clockwise directions, 3 rotations counterclockwise of driven gear, drive screw mandrel 6 rotation counterclockwise, the distance between positive tooth nut 7 and the anti-tooth nut 8 becomes near, makes that the angle between cross pipe 15 and the cross pipe 16 diminishes, it is connector 11, connector 14, the angle that connector is 12 3 diminishes, and connector 14 is towards stretching away from screw mandrel 6 directions, again because connector 14, connector 18, connector 21 and connector 17 constitute parallelogram, so the angle between cross pipe 19 and the cross pipe 20 also becomes big, it is connector 17, connector 21, the angle that connector is 18 3 diminishes, and connector 21 is also towards stretching away from screw mandrel 6 directions.Equally, the cross pipe assembly of back level cascade also stretches in the same direction, and restrictor bar stretches elongatedly like this, runs to the position of limit switch 9 up to anti-tooth nut 8, stops contraction, as shown in Figure 1.
Comprehensively the above changes the distance between travel switch 9 and the travel switch 10, and promptly the angle between the cross pipe that links to each other in the middle part of the control just can be controlled the along continuous straight runs contractile motion of restrictor bar, thereby controls the length of restrictor bar.
