Description

Technical Field

[0001] The utility model relates to the technical field of barrier gates, and in particular to an extendable barrier gate device. Background Art

[0002] An extendable barrier device is an entrance and exit management device used to manage vehicle traffic. This device is generally widely used in roads, residential areas, parking lots and other occasions to achieve effective management of vehicle passages.

[0003] The existing patent CN214656604U discloses a horizontally retractable barrier railing, comprising: a box, a driving mechanism, an active rod, a driven rod, a first connecting rod and a second connecting rod, wherein the first connecting rod and the second connecting rod are cross-rotatably connected to define an X-shaped connecting rod assembly.

[0004] This patent solves the problem that due to the limitation of the narrow space height, the railing with constant length cannot smoothly complete the transition between prohibition and release when raising and lowering. The above technical solution sets up a driving mechanism and a connecting rod structure, and the driving assembly drives the main rod to move, thereby driving the entire connecting rod to retract, thereby avoiding the problem of failure to complete lifting due to insufficient upper and lower space.

[0005] The above scheme also has the problem that after the connecting rods complete the contraction work, they will gather together, resulting in the problem that vehicles cannot pass through well. Specifically, when using an extendable barrier gate in the horizontal direction, due to the structural problem of the connecting rods themselves, after the contraction is completed, the connecting rods will gather together. In the case of limited space, the vehicle travel distance will become narrower, resulting in the problem that vehicles cannot pass through well. Therefore, the utility model proposes an extendable barrier gate device. Utility Model Content

[0016] One end of the first bevel gear is fixedly connected to the inner wall of the box body, and the surfaces of the first bevel gear and the second bevel gear are provided with mutually meshing teeth. One end of the second bevel gear is fixedly connected to the telescopic rod, and the telescopic rod and the second bevel gear are movably connected to the threaded rod. The rotational force brought by the motor to the second bevel gear through the screw is transmitted to the first bevel gear, so that the second bevel gear can rotate.

[0028] Further, such as Figure 2 and Figure 4As shown: the inner cavity of the box body 1 is provided with a driving component 3, and the driving component 3 includes a second supporting block 31, and a motor 32 is provided at one end of the second supporting block 31, and the output end of the motor 32 is fixedly connected to the transmission rod 33, and a threaded rod 34 is provided at one end of the transmission rod 33, and a first slider 35 is provided on the surface of the threaded rod 34, and a third slider 38 is provided at one end of the first slider 35, and one end of the third slider 38 extends to the inner cavity of the first slide groove 11, and the third slider 38 is slidably connected with the inner cavity of the first slide groove 11, and an interception component 2 is provided at one end of the first slider 35, and the interception component 2 includes a first supporting block 21, a first A connecting block 22 is provided at the bottom of the support block 21, a first connecting rod 23 is provided in the inner cavity of the connecting block 22, a third connecting rod 25 is provided on the side of the first connecting rod 23 away from one end of the connecting block 22, a landing foot 28 is provided on the side of one end of the third connecting rod 25, a second connecting rod 24 is provided at one end of the first slider 35, a first supporting rod 26 is provided on the side of one end of the second connecting rod 24, and a second supporting rod 27 is provided on the other side of the second connecting rod 24. The second supporting block 31 is rotatably connected to the motor 32 through a bearing. By providing the motor 32, the transmission rod 33 can be driven to rotate, and when the transmission rod 33 rotates, it can be extended The retractable rod 37 drives the threaded rod 34 to rotate, and when the threaded rod 34 rotates, it can drive the first slider 35 to move. The third slider 38 cooperates with the first slide groove 11 to ensure the stability of the movement trajectory and avoid deviation during movement. When in use, after the vehicle passes, the motor 32 is restarted, and the output shaft of the motor 32 is reversed, so that the first slider 35 can be driven to move upward. When the first slider 35 rises, it can drive the second connecting rod 24 to move upward. When the second connecting rod 24 moves upward, it can simultaneously drive the first support rod 26 and the second support rod 27 to move upward. When the second support rod 27 moves upward, it can drive the third The first connecting rod 23 moves upward, and at the same time, the first support rod 26 can drive the third connecting rod 25 to move. Since the stroke is shortened during the rising process of the second connecting rod 24, an outward thrust is formed, which can push the landing foot 28 to move outward, thereby achieving the effect of intercepting the vehicle. When the second connecting rod 24 moves upward, the second support rod 27 cooperates with the first connecting rod 23 to limit the movement trajectory of the second connecting rod 24. When the landing foot 28 moves outward, the first support rod 26 and the third connecting rod 25 cooperate to limit the movement trajectory of the landing foot 28 to avoid deviation during operation.

[0029] After the first bevel gear 41 and the second bevel gear 43 are engaged to complete the rotation of the interception assembly 2, the interception assembly 2 cannot perform a reset action when the second bevel gear 43 is directly disengaged. Figure 3 and Figure 4As shown: a telescopic rod 37 is provided on the side of the first slider 35, and a threaded hole 36 is opened on the side of the first slider 35. This design makes it possible to reset the interception assembly 2 by starting the motor 32 after the rotation work is completed. Specifically, after the rotation work is completed, by starting the motor 32, the output shaft of the motor 32 is reversed, thereby driving the first slider 35 to move upward. When the first slider 35 moves upward, it will first drive the telescopic rod 37 to move upward. When the telescopic rod 37 is stretched, the first bevel gear 41 and the fixed block 42 cooperate to complete the reverse rotation of the interception assembly 2, thereby achieving the effect of resetting the interception assembly 2 and avoiding the problem that the interception assembly 2 cannot be reset when directly detached.

[0030] Working principle:

[0031] like Figure 1-4 As shown:

[0032] When in use: when encountering a vehicle, first start the motor 32, the output shaft of the motor 32 rotates forward, so that the threaded rod 34 can be driven to rotate through the transmission rod 33, and the threaded rod 34 cooperates with the threaded hole 36, so that the first slider 35 can be driven to move downward. When the first slider 35 moves downward, it can drive the second connecting rod 24 to move downward. When the second connecting rod 24 moves downward, it also drives the second support rod 27 and the first support rod 26 to move downward. The distance between the support rods is reduced, so that the landing foot 28 can be driven to move inward. At the same time, when the first slider 35 moves downward, the telescopic rod 37 will be telescoped. After the telescopic rod 37 is telescoped, it pushes the second bevel gear 43 to move downward. When the surfaces of the second bevel gear 43 and the first bevel gear 41 are meshed, the second slider 44 extends to the inner cavity of the second slide groove 45, so that the rotation force can be transmitted The motor 32 is then started and the output shaft of the motor 32 is reversed to drive the first slider 35 to move upward. When the first slider 35 moves upward, the first slider 35 drives the second connecting rod 24 to rise. Since the spacing is shortened during the rising process of the second connecting rod 24, an outward thrust is formed, thereby pushing the landing foot 28 to move outward. At the same time, when the first slider 35 moves upward, it will first drive the telescopic rod 37 to move upward. When the telescopic rod 37 is stretched, the first bevel gear 41 and the fixed block 42 cooperate to complete the reverse rotation of the interception assembly 2, thereby achieving the effect of resetting the interception assembly 2, and then achieving the effect of intercepting and releasing the vehicle.
