Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission, and in particular to a hoop-type angle adjustable device that can adjust the horizontal angle of a gate arm. Background Technology

[0002] The length of the barrier arm varies depending on the usage environment (up to 8m). The arm is heavy and slender, and may bend and sag after installation. Furthermore, due to space constraints in the external housing, the angle error of the articulated arm linkage mechanism is magnified exponentially as the ratio of the arm's length to the swing arm's length increases. In actual installation, refer to... Figure 1 To achieve a basic horizontal position for the gate arm 1a, the angle between the gate arm 1a and the swing arm 3a must be adjusted. A common solution is to use a simple clamp-type (keyless) connection between the swing arm shaft 5a and the swing arm 3a. However, this method has drawbacks: the angle adjustment range is too large, there is no basic reference angle between the gate arm 1a and the swing arm 3a during assembly, installation and debugging are time-consuming and labor-intensive, and the clamp-type keyless connection poses certain safety hazards, as the clamp-type structure is prone to loosening and causing the gate arm to fall to the ground. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide a hoop-type angle adjustable device capable of adjusting the horizontal angle of the gate arm.

[0004] This utility model is achieved through the following technical measures: a hoop-type adjustable angle device, including a main unit and a gate arm. The main unit drives the gate arm to swing up and down through a swinging crank arm. A swing rod shaft is connected between the swinging crank arm and the gate arm. The two ends of the swing rod shaft are respectively inserted into the shaft holes of the swinging crank arm or the gate arm. An adjustable structure is provided between the swinging crank arm and the swing rod shaft or / and between the swing rod shaft and the gate arm. The adjustable structure includes at least one adjusting screw hole eccentrically disposed on the shaft hole wall. The adjusting screw hole passes through the shaft hole wall, and an adjusting screw is threaded in the adjusting screw hole. Rotating the adjusting screw causes it to eccentrically press against the swing rod shaft, thereby causing relative rotation between the swinging crank arm and the swing rod shaft or / and between the swing rod shaft and the gate arm.

[0005] As a preferred embodiment, the adjusting screw holes are two located on both sides of the rocker arm shaft.

[0006] As a preferred embodiment, the adjusting screw holes are two symmetrically arranged on both sides of the rocker arm shaft.

[0007] As a preferred embodiment, the rocker arm shaft is provided with a groove corresponding to the adjusting screw hole.

[0008] As a preferred embodiment, the groove is a plane.

[0009] As a preferred embodiment, the end of the adjusting screw that presses against the rocker arm shaft has an arc surface.

[0010] As a preferred embodiment, the adjustable structure includes an adjusting screw hole eccentrically disposed on the shaft hole wall and an elastic structure elastically disposed between the swing arm and the swing rod shaft and / or between the swing rod shaft and the gate arm.

[0011] As a preferred embodiment, the elastic structure is a spring.

[0012] In a preferred embodiment, the gate arm is connected to the handle, and the adjustable structure is disposed on the handle.

[0013] In a preferred embodiment, the motor of the main unit drives the active crank arm to rotate via a gearbox, and the active crank arm drives the swinging crank arm to swing via a connecting rod.

[0014] This invention features an adjustable structure between the swing arm and the swing rod shaft, and / or the swing rod shaft and the gate arm. When the gate arm forms a certain angle with the horizontal after lowering, the angle can be corrected by rotating the adjusting screw to make it eccentrically press against the swing rod shaft, causing relative rotation between the swing arm and the swing rod shaft, and / or the swing rod shaft and the gate arm. This adjustment device can adjust the gate arm's angle relative to the swing arm. This invention also prevents the gate arm from falling while adjusting its level. Attached Figure Description

The two ends of the swing rod shaft 3 are respectively inserted into the shaft holes of the swinging crank arm 4 or the gate arm 1. An adjustable structure is provided between the swinging crank arm 4 and the swing rod shaft 3 or / and between the swing rod shaft 3 and the gate arm 1. The adjustable structure includes at least one adjusting screw hole 201 or / and 401 eccentrically disposed on the shaft hole wall. The adjusting screw holes 201 and 401 pass through the shaft hole wall. An adjusting screw 5 is internally threaded in the adjusting screw holes 201 and 401. Rotating the adjusting screw 5 causes it to eccentrically press against the swing rod shaft 3, thereby causing the swinging crank arm 4 and the swing rod shaft 3 or / and the swing rod shaft 3 and the gate arm 1 to rotate relative to each other.

[0022] This adjustment device features an adjustable structure between the swing arm 4 and the swing shaft 3, or / and the swing shaft 3 and the gate arm 1. When the gate arm 1 forms a certain angle with the horizontal after being lowered, the adjusting screw 5 can be rotated to eccentrically press against the swing shaft 3, causing relative rotation between the swing arm 4 and the swing shaft 3, or / and the swing shaft 3 and the gate arm 1, thus correcting the angle and adjusting the angle between the gate arm 1 and the swing arm 4. This adjustment device can adjust the gate arm's level while preventing it from falling.
