Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of motor vehicle gate equipment, and particularly relates to a height adjustable barrier lever. BACKGROUND
[0002] In the motor vehicle gate equipment, the barrier lever as a core component is mainly used for controlling vehicle passing. The traditional barrier lever is usually composed of a front lever, a rear lever, a pull rod and a connecting piece, and the connecting structure thereof is mostly designed in a fixed mode. Specifically, the pull rod connecting piece rigidly connects the front lever, the rear lever and the pull rod through bolts, wherein the front lever and the rear lever are horizontally aligned, and the rear lever is fixedly connected with a driving motor or a transmission mechanism at the end thereof, and the lifting or rotation of the barrier lever is realized by the driving motor. This design can meet the basic requirements in the conventional scene, but gradually exposes the following problems in the special application scene:
[0003] 1. Poor adaptability due to fixed height
[0004] The front lever and the rear lever of the traditional barrier lever are fixed through the horizontally connected pull rod, and the installation height of the rear lever is limited by the fixed position of the driving motor. Therefore, the height of the front lever from the ground cannot be adjusted. For example, when temporary adjustment of vehicle height limit (such as special vehicle passing, construction area) or coping with different vehicle models (such as mixed driving of trucks and cars) is required, the barrier lever with fixed height cannot be flexibly adapted, and it is necessary to replace parts or adjust the whole device, which is cumbersome and costly.
[0005] 2. Limited application in special scene
[0006] In places where the ground height is uneven, such as slopes and parking lot entrances, the barrier lever with fixed height is prone to uneven gap between the front lever and the ground due to ground inclination, which may cause accidental collision or scratching. In addition, some places (such as logistics parks and airports) need to dynamically adjust the height of the barrier lever according to time period or task, and the traditional design cannot meet such requirements. SUMMARY
[0007] The utility model aims at providing a height adjustable barrier lever to solve the problems raised in the background.
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a height adjustable barrier lever, comprising a pull rod, a front lever, a rear lever and a pull rod connecting piece, the rear lever and the pull rod are connected with a device transmission mechanism for driving the rotation of the barrier lever.
[0009] The pull rod connecting piece is in a stepped shape, comprising a fixed connecting part and a front lever mounting part arranged left and right;
[0010] The waist hole vertically extends on the front rod mounting portion of the pull rod connector, the tail end of the front rod is adjustably connected with the pull rod connector through the bolt penetrating the waist hole, and the front rod can vertically move along the waist hole to adjust the height.
[0011] Preferably, the top between the two upper fixed connecting portions and the two front rod mounting portions is jointly connected with a reinforcing connecting plate.
[0012] Preferably, the tail end of the front rod is provided with a U-shaped mounting plate matched with the waist hole, the two side plate surfaces of the U-shaped mounting plate are locked through the double-side bolt penetrating the waist hole, the connection stability of the front rod and the waist hole is improved, and single-side stress loosening is prevented.
[0013] Preferably, the tail end of the rear rod is provided with a flange plate coaxially fixed with the driving shaft of the barrier equipment through the bolt, the rear rod is driven to rotate by the driving shaft, the power transmission efficiency is ensured, and the transmission loss is reduced.
[0014] Preferably, the lower surface of the front rod is provided with an antiskid rubber pad for buffering the contact with the ground when the rod is lowered.
[0015] Preferably, a scale mark is arranged beside the waist hole for indicating the adjusted height value of the front rod, the user experience and operation safety are improved, and more application scenarios are covered.
[0016] The technical effects and advantages of the utility model are as follows:
[0017] 1. Height adjustment is flexible, and the application scenarios are wide: through the waist hole structure of the L-shaped pull rod connector, the front rod can vertically move and be locked and fixed, without relying on external power (such as a hydraulic or electric device), the height of the rod can be quickly adjusted, and the utility model is suitable for complex scenes such as ramps and height-limited areas. Compared with the traditional fixed rod, the utility model solves the problem of uneven gap caused by uneven ground or different vehicle types, and reduces the collision risk.
[0018] 2. The structure is stable and durable: the pull rod connector is fixed with the U-shaped mounting plate through the double-side bolt, the connection strength is improved, and loosening after long-term use is avoided.
[0019] 3. The operation is simple and the cost is low: the manual adjustment design (such as loosening the bolt and sliding the front rod) does not need to additionally configure a power source or a control module, the manufacturing cost and maintenance difficulty are significantly reduced, and the utility model is suitable for low-cost scenes. Compared with the electronic rod or the hydraulic adjustment scheme, the utility model reduces the fault risk of complex circuit or power system.
[0020] 4. Safety protection and precision improvement: the scale mark beside the waist hole and the limiting protrusion provide visual height adjustment reference and limit the moving range to prevent structural dislocation caused by operation errors. The antiskid rubber pad on the lower surface of the front rod buffers the ground impact, reduces the equipment wear and noise.BRIEF DESCRIPTION OF DRAWINGS BRIEF DESCRIPTION OF DRAWINGS
